The association between ulcerative colitis (UC) and erectile dysfunction (ED) has been previously reported. Numerous previous studies have also reported an association between gastrointestinal symptoms and ED. Constipation and diarrhea are common in patients with UC. However, the specific association between bowel movement frequency and ED remains unclear. The aim of this study is to investigate the association between bowel movement frequency and ED in 164 patients with UC. The definition of ED, moderate to severe ED, and severe ED was the Sexual Health Inventory for Men score <22, <12, and <8, respectively. Bowel movement frequency was divided into three categories: (1) high (More than once a day), (2) normal (once a day, reference), and low (less than one time/day). The definition of constipation was based on the Rome I criteria and/or medication for constipation. The prevalence of constipation and ED was 10.4% and 86.0%, respectively. The rate of high, normal, and low bowel movement frequency was 56.1%, 25.0%, and 18.9%, respectively. High bowel movement frequency was independently and positively associated with ED and moderate to severe ED (ED: adjusted odds ratio [OR] 4.42, 95% confidence interval [CI] 1.35-15.98; moderate to severe: adjusted OR 2.98, 95% CI 1.22-7.61). Low bowel movement frequency was independently and positively associated with moderate to severe ED and severe ED (moderate to severe: adjusted OR 3.96, 95% CI 1.27-13.08; severe: adjusted OR 3.20, 95% CI 1.08-9.86). No association between constipation and ED was found. In conclusion, in Japanese patients with UC, both high and low bowel movement frequency were independently and positively associated with ED.

BACKGROUND: Poor lifestyle habits may worsen nonalcoholic fatty liver disease (NAFLD), with progression to nonalcoholic steatohepatitis (NASH) and cirrhosis. This study investigated the association between glycemic control status and hepatic histological findings to elucidate the effect of glycemic control on NAFLD. METHODS: This observational study included 331 patients diagnosed with NAFLD by liver biopsy. Effects of the glycemic control status on histological findings of NAFLD were evaluated by comparing the following four glycemic status groups defined by the glycosylated hemoglobin (HbA1c) level at the time of NAFLD diagnosis: ≤5.4%, 5.5%-6.4%, 6.5%-7.4%, and ≥7.5%. RESULTS: Compared with the lowest HbA1c group (≤5.4%), the higher HbA1c groups (5.5%-6.4%, 6.5%-7.4%, and ≥7.5%) were associated with advanced liver fibrosis and high NAFLD activity score (NAS). On multivariate analysis, an HbA1c level of 6.5%- 7.4% group was significantly associated with advanced fibrosis compared with the lowest HbA1c group after adjusting for age, sex, hemoglobin, alanine aminotransferase, and creatinine levels. When further controlling for body mass index and uric acid, total cholesterol, and triglyceride levels, the higher HbA1c groups were significantly associated with advanced fibrosis compared with the lowest HbA1c group. On the other hand, compared with the lowest HbA1c group, the higher HbA1c groups were also associated with a high NAS in both multivariate analyses. CONCLUSION: Glycemic control is associated with NAFLD exacerbation, with even a mild deterioration in glycemic control, especially a HbA1c level of 6.5%-7.4%, contributing to NAFLD progression.

Socioeconomic status is a risk factor for poor disease prognosis. No studies of patients with ulcerative colitis (UC) have investigated the association between socioeconomic status and erectile dysfunction (ED), although UC is independently positively associated with ED. Therefore, the purpose of this survey to evaluate this issue in Japanese patients with UC. The study enrolled 165 patients with UC. Education status (low, middle, high) and household income (low, middle, high) were classified in three groups using self-administered surveys. The information regarding the Sexual Health Inventory for Men (SHIM) was obtained using self-administered questionnaires. The definition of mild to moderate or severe ED and severe ED was SHIM score <17 and SHIM score <8, respectively. The prevalence of mild to moderate or severe ED and severe ED was 64.9% and 47.9%, respectively. In crude analysis, household income was inversely associated with mild to moderate or severe ED and severe ED. After adjustment for age, current drinking, current smoking, exercise habit, body mass index, mucosal healing, and duration of UC, high household income was independently and inversely associated with mild to moderate or severe ED (adjusted odds ratio [OR] 0.23, 95% confidence interval [CI] [0.05, 0.93], p for trend = .038) and severe ED (adjusted OR 0.26, 95% CI [0.07, 0.85], p for trend = .024). In contrast, no association between education status and ED was found. In conclusion, household income was independently and inversely associated with ED in Japanese UC patients.

BACKGROUND AND AIM: Although diet is one of the potential environmental factors affecting ulcerative colitis (UC), evidence is not sufficient to draw definitive conclusions. This Japanese case-control study examined the association between the consumption of coffee, other caffeine-containing beverages and food, and total caffeine and the risk of UC. METHODS: The study involved 384 UC cases and 665 control subjects. Intake of coffee, decaffeinated coffee, black tea, green tea, oolong tea, carbonated soft drinks, and chocolate snacks was measured with a semiquantitative food-frequency questionnaire. Adjustments were made for sex, age, pack-years of smoking, alcohol consumption, history of appendicitis, family history of UC, education level, body mass index, and intake of vitamin C, retinol, and total energy. RESULTS: Higher consumption of coffee and carbonated soft drinks was associated with a reduced risk of UC with a significant dose-response relationship (P for trend for coffee and carbonated soft drinks were <0.0001 and 0.01, respectively), whereas higher consumption of chocolate snacks was significantly associated with an increased risk of UC. No association was observed between consumption of decaffeinated coffee, black tea, green tea, or oolong tea and the risk of UC. Total caffeine intake was inversely associated with the risk of UC; the adjusted odds ratio between extreme quartiles was 0.44 (95% confidence interval: 0.29-0.67; P for trend <0.0001). CONCLUSIONS: We confirmed that intake of coffee and caffeine is also associated with a reduced risk of UC in Japan where people consume relatively low quantities of coffee compared with Western countries.

INTRODUCTION: There is evidence regarding the association between dysmenorrhea and irritable bowel syndrome (IBS), although it is lacking in the Asian population. Therefore, the purpose of this study was to investigate the association between menstrual status and IBS in a young Japanese. METHODS: Overall, 4693 female college students were included in the analysis of this study. Information regarding lifestyle habits, menstrual status (irregularity, pain severity, and medication), and IBS (Rome III criteria) was obtained using a self-reported questionnaire. Age, body mass index, exercise habits, smoking, drinking habits, and anemia were analyzed as potential confounders. RESULTS: The prevalence of IBS was 6.1%. Moderate (adjusted odds ratio [OR]: 1.89 [95% confidence interval (CI): 1.27-2.91]) and heavy (adjusted OR: 2.14 [95% CI: 1.42-3.45]) menstrual pain was independently positively associated with IBS (p for trend = 0.001). Using medication sometimes (adjusted OR: 1.41 [95% CI: 1.09-1.84]) and often (adjusted OR: 1.60 [95% CI: 1.13-2.24]) was independently positively associated with IBS. There was no association between menstrual cycle and IBS. In subjects without functional dyspepsia, irregular menstrual cycle was independently positively associated with IBS. CONCLUSION: In the young Japanese population, menstrual pain and medications for menstrual pain may have a significant positive association with IBS.

Hepatitis B vaccine induces the production of antibodies against hepatitis B surface antigen (anti-HBs) and prevents hepatitis B virus (HBV) infection. However, 5-10% of individuals cannot develop anti-HBs even after multiple vaccinations (HB vaccine non-responders). We developed an intranasal vaccine containing both HBs antigen (HBsAg) and HB core antigen (HBcAg) and mixed it with a viscosity enhancer, carboxyl vinyl polymer (CVP-NASVAC). Here, we investigated the prophylactic capacity of CVP-NASVAC in HB vaccine non-responders. Thirty-four HB vaccine non-responders were administered three doses of intranasal CVP-NASVAC. The prophylactic capacity of CVP-NASVAC was assessed by evaluating the induction of anti-HBs and anti-HBc (IgA and IgG) production, HBV-neutralization activity of sera, and induction of HBs- and HBc-specific cytotoxic T lymphocytes (CTLs). After CVP-NASVAC administration, anti-HBs and anti-HBc production were induced in 31/34 and 27/34 patients, respectively. IgA anti-HBs and anti-HBc titers significantly increased after CVP-NASVAC vaccination. HBV-neutralizing activity in vitro was confirmed in the sera of 26/29 CVP-NASVAC-administered participants. HBs- and HBc-specific CTL counts substantially increased after the CVP-NASVAC administration. Mild adverse events were observed in 9/34 participants; no serious adverse events were reported. Thus, CVP-NASVAC could be a beneficial vaccine for HB vaccine non-responders.

OBJECTIVE: To investigate the association between nocturia and constipation in patients with ulcerative colitis (UC). Constipation has recently been recognized as an important symptom in patients with UC. Although nocturia has been associated with constipation in the general population, the association between nocturia and constipation in UC patients is uncertain. METHODS: Consecutive series of 290 Japanese patients with UC, Information on constipation, nocturia, and lifestyle habits was obtained using self-administered questionnaires. The definition of constipation was based on Rome I criteria and/or current medication for constipation. Patients were divided into three groups based on nighttime urination: 1) no nocturia, 2) mild nocturia (nocturnal urination - one), and 3) serious nocturia (nocturnal urination - two or more). Multivariate logistic regression was used to evaluate the association between nocturia and constipation. RESULTS: Among all of the UC patients, the prevalence of mild nocturia, serious nocturia, and constipation was 35.2%, 26.9%, and 12.4%, respectively. The prevalence of constipation in the none, mild, and serious nocturia groups was 8.2%, 10.8%, and 20.5%, respectively. After adjustment for confounders such as age, sex, current drinking, current smoking, body mass index, and steroid use, nocturia severity was independently and positively associated with constipation (adjusted odds ratio for mild nocturia: 1.55 [95% confidence interval: 0.57-4.28], serious nocturia: 3.19 [95% confidence interval: 1.09-9.81], p for trend = 0.035). CONCLUSIONS: The severity of nocturia is positively associated with constipation, and physicians should consider the interrelationships between nocturia and constipation in managing UC patients.

OBJECTIVE: Evidence regarding the association between exercise habits and irritable bowel syndrome (IBS) remains scarce in a young population. It is also unknown whether the existence of an exercise partner affects this issue. The purpose of this study was to explore the association between exercise habits that include an exercise partner and IBS in a young Japanese population. METHODS: This study enrolled 8923 Japanese university students and examined exercise frequency and intensity, and exercise partners using self-administered questionnaires. IBS and functional dyspepsia were defined according to the Rome III criteria. RESULTS: The prevalence of IBS in this survey was 6.5%. Moderate frequency exercise was inversely related with IBS [adjusted odds ratio (aOR): 0.65 (95% confidence interval, CI: 0.51-0.83), P for trend = 0.005]. Moderate and high exercise intensities were independently and inversely related with IBS, respectively [aORs were moderate: 0.76 (95% CI: 0.61-0.95) and high: 0.62 (95% CI: 0.48-0.78), P for trend = 0.001]. Exercising with a group or with friends instead of alone was independently inversely related with IBS [aOR with groups: 0.53 (95% CI: 0.40-0.70) and with friends: aOR 0.71 (95% CI: 0.54-0.93)]. After excluding subjects with overlapping IBS and functional dyspepsia, an inverse association between high intensity of exercise or exercise in a group and IBS remained significant. CONCLUSION: The frequency and intensity of exercise may be independently inversely related with IBS in a young Japanese population. Also, exercise with others may be important for preventing IBS.

AIM: Hepatitis C complicated by diabetes mellitus (DM) is considered a risk factor for the progression of fibrosis and development of hepatocellular carcinoma (HCC) and cardiovascular diseases. However, several studies may have lacked appropriate diagnosis of glucose intolerance. We aimed to examine the risk associated with abnormal glucose intolerance in the development of liver-related diseases, including HCC and complications of liver cirrhosis, such as ascites, esophageal and gastric varices, and hepatic encephalopathy, and cardiovascular diseases in patients with hepatitis C accurately diagnosed with impaired glucose tolerance. METHODS: This longitudinal retrospective study included 365 patients with chronic hepatitis C admitted to Ehime University Hospital for anti-hepatitis C therapy between September 1991 and January 2015. Patients were classified into normal glucose tolerance (NGT), prediabetes, and DM groups based on 75-g oral glucose tolerance test results. RESULTS: Both univariate and multivariate (adjusted for potential confounders) analyses revealed a significantly higher risk of developing HCC and cardiovascular events in the DM group than in the NGT group. However, in multivariate analysis, liver-related events, particularly liver cirrhosis complications, revealed no significant association. In addition, the prediabetes group had no significant risk of any outcome. CONCLUSIONS: Patients with hepatitis C complicated by DM, compared with patients with hepatitis C with NGT or complicated with prediabetes, have a higher risk of HCC and cardiovascular disease events, but not liver-related events, particularly in not developing liver cirrhosis complications. Therefore, appropriate follow-up is required for patients with hepatitis C based on their glucose tolerance status.

INTRODUCTION AND IMPORTANCE: When treating adrenocorticotropic hormone (ACTH)-producing adenoma, accurate tumor localization is critical. We report a case of Cushing's disease in which MRI with a spoiled-gradient echo 3D T1-weighted sequence was useful in precise localization of an ACTH-producing adenoma and deciding appropriate treatment strategy. CASE PRESENTATION: A 47-year-old woman was admitted to our hospital with signs and symptoms of Cushing's disease. Laboratory findings showed hypercortisolemia and suggested Cushing's disease. However, neuroimaging on conventional pituitary MRI using a spin-echo (SE) protocol did not confirm pituitary adenoma in the sella turcica. Inferior petrosal sinus sampling suggested a higher central/peripheral ratio of ACTH after corticotropin-releasing hormone (CRH) administration on the right side. Reviewing the dynamic MRI using an SE protocol from that perspective, we vaguely identified a 5.0 mm area of gradual contrast on the right side of the pituitary gland. In addition, pituitary MRI with a spoiled-gradient echo 3D T1-weighted sequence, a 2.0 mm hypo-enhancing region was identified on the right side within the anterior pituitary gland. The tumor was resected completely removing the right pituitary gland including the tumor. The histological diagnosis was ACTH-producing pituitary adenoma. Symptoms of Cushing's disease gradually improved and endocrinological function normalized. Follow-up neuroimaging after 1 year showed no signs of recurrence. CLINICAL DISCUSSION: In the treatment of Cushing's disease, accurate detection of ACTH-producing pituitary adenoma is crucial to maximizing curative rates. However, exact confirmation of the tumor location is very difficult. CONCLUSION: MRI with a spoiled-gradient echo 3D T1-weighted sequence may facilitate accurate tumor localization and appropriate treatment strategy.

BACKGROUND: The association between disease activity and erectile dysfunction (ED) in patients with inflammatory bowel disease (IBD) is inconsistent, although IBD, including ulcerative colitis (UC), is reported as a risk factor for ED. AIM: The purpose of this study was to explore this association in Japanese patients with UC. METHODS: In this study, we enrolled 165 Japanese male patients with UC. Information regarding the Sexual Health Inventory for Men (SHIM) score, medication, and severity of UC was obtained from medical records, self-administered questionnaires, and reports from physicians. The definition of ED and severe ED is a SHIM score <17 and <8, respectively. OUTCOMES: No association between severity of UC and ED was found in Japanese patients. Aging is independently positively associated with ED in patients with UC. RESULTS: The prevalence of severe ED and ED was 47.9% and 64.9%, respectively. In this study, mucosal healing, clinical remission, duration of UC, disease extent, and medication were not associated with the prevalence of ED. Older age (≥63 years of age) was independently positively associated with ED (adjusted odds ratio, 12.93; 95% CI: 4.51-43.00) and severe ED (adjusted odds ratio, 9.02; 95% CI: 3.66-23.91). CLINICAL IMPLICATIONS: Disease severity of UC might not be associated with the prevalence of ED in patients with UC. STRENGTHS AND LIMITATIONS: This is the first study to investigate the association between several factors regarding UC activity and ED. The limitation of this study is the definition of ED based on SHIM scores. CONCLUSION: No association between severity of UC and ED was found in Japanese patients. As expected, aging may be independently positively associated with ED in patients with UC.

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease all over the world. Therapeutic strategies targeting its multidirectional pathways are required. Particularly, fibrosis is closely associated with its prognosis. We previously found that B cell-activating factor (BAFF) is associated with severity of NAFLD. Here, we determined the direct in vivo role of BAFF in the development of liver fibrosis. Histological and biochemical analyses were performed using wild-type and BAFF-deficient mice. We established a murine model of non-alcoholic steatohepatitis (NASH) using carbon tetrachloride injection accompanied by high-fat/high-cholesterol diet feeding. Additionally, in vitro analysis using mouse macrophage-like cell line RAW264.7 and primary hepatic stellate cells was performed. Hepatic steatosis and inflammation, and most importantly, the progression of liver fibrosis, were ameliorated in BAFF-deficient mice compared to those wild-type mice in our model. Additionally, BAFF deficiency reduced the number of CD11c+ M1-type macrophages in the liver. Moreover, BAFF stimulated RAW264.7 cells to secrete nitric oxide and tumor necrosis factor α, which drove the activation of hepatic stellate cells. This indicates that BAFF plays a crucial role in NASH development and may be a promising therapeutic target for NASH.

Patients with viral hepatitis-related chronic liver disease (CLD) under surveillance for hepatocellular carcinoma (HCC) are often diagnosed with pancreatic cancer (PC) at an early stage. However, the long-term outcomes of these patients are unclear. We aimed to clarify the long-term outcomes of patients with PC with viral hepatitis-related CLD using a chart review. Data collection included the Union for International Cancer Control (UICC) stage at PC diagnosis, hepatitis B virus and hepatitis C virus status, and long-term outcomes. The distribution of the entire cohort (N = 552) was as follows: early stage (UICC 0-IB; n = 52, 9.5%) and non-early stages (UICC IIA-IV; n = 500, 90.5%). At diagnosis, the HCC surveillance group (n = 18) had more patients in the early stages than the non-surveillance group (n = 534) (50% vs. 8.0%), leading to a higher indication rate for surgical resection (72.2% vs. 29.8%) and a longer median survival time (19.0 months vs. 9.9 months). We confirmed that patients with viral hepatitis-related CLD under HCC surveillance were diagnosed with PC at an early stage. Because of the higher indication rate for surgical resection in these patients, they had favorable long-term outcomes for PC.

Results: Both univariate and multivariate (adjusted for potential confounders) analyses revealed a significantly higher risk of developing HCC and cardiovascular events in the DM group than in the NGT group. However, in multivariate analysis, liver-related events, particularly liver cirrhosis complications, revealed no significant association. In addition, the prediabetes group had no significant risk of any outcome. Conclusions: Patients with hepatitis C complicated by DM, compared with patients with hepatitis C with NGT or complicated with prediabetes, have a higher risk of HCC and cardiovascular disease events, but not liver-related events, particularly in not developing liver cirrhosis complications. Therefore, appropriate follow-up is required for patients with hepatitis C based on their glucose tolerance status.

INTRODUCTION: Recent meta-analysis showed that ulcerative colitis (UC) is a risk factor for cardiovascular disease (CVD). Dyslipidemia is a well-established risk factor for CVD. However, evidence regarding inflammatory bowel disease (IBD), including UC and lipid profiles, is limited. Additionally, no study has assessed the association between endoscopic activity and lipid profiles in patients with IBD. Therefore, we aimed to clarify the association between mucosal healing (MH) and lipid profiles in patients with UC. METHODS: A total of 221 Japanese patients with UC were enrolled in this analysis. Total cholesterol (T-chol), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) were divided into tertiles (high, moderate, and low) based on the distributions, respectively. Self-administered questionnaire was used to obtain information regarding medication for dyslipidemia. Complete MH and MH are based on Mayo endoscopic subscore 0 and 0-1, respectively. RESULTS: The percentage of complete MH was 30.8%. In patients without medication for dyslipidemia, high HDL-C (>66 mg/dL) was significantly positively associated with complete MH (adjusted odds ratio [OR] 2.58, 95% CI: 1.04-6.64, p for trend = 0.037). In patients with nonproctitis, a positive association between HDL-C and complete MH was found (adjusted OR 3.54, 95% CI: 1.22-11.01, p for trend = 0.020). T-chol and TG were not associated with MH, regardless of medication for dyslipidemia. CONCLUSIONS: Complete MH was significantly positively associated with HDL-C in UC patients without medication for lipid. The disease extent might affect the association between complete MH and HDL-C.

Restless legs syndrome (RLS) is a common sleep disorder in the Western population. The prevalence of restless legs syndrome in the Japanese population is 4.6%. Inflammatory and/or immune alteration might be associated with the development of restless legs syndrome. Ulcerative colitis is a chronic inflammatory bowel disease. Evidence regarding the association between ulcerative colitis and the prevalence of restless legs syndrome is limited. Herein, we investigated the association between clinical outcomes and the prevalence of restless legs syndrome in Japanese patients with ulcerative colitis. This was a cross-sectional study using baseline data from a prospective cohort study. Subjects in this study were 273 patients with ulcerative colitis. The definition of restless legs syndrome was achieved using a self-administered questionnaire based on the diagnostic criteria for restless legs syndrome in an epidemiological study approved by the Executive Committee of the International Restless Leg Syndrome Study Group in 2002. Clinical outcomes were clinical remission and mucosal healing. The association between clinical remission and mucosal healing and the prevalence of restless legs syndrome was assessed by multivariate logistic regression analyses. The percentage of clinical remission and mucosal healing was 58.4% and 63.1%, respectively. The prevalence of restless legs syndrome in this cohort was 4.7%. Clinical remission (adjusted odds ratio 0.23, 95% confidence interval 0.05-0.93) and mucosal healing (adjusted odds ratio 0.23, 95% confidence interval 0.05-0.90) were independently inversely associated with restless legs syndrome. No association between serum haemoglobin and restless legs syndrome was found. In conclusion, clinical remission and mucosal healing were independently and inversely associated with the prevalence of restless legs syndrome in Japanese patients with ulcerative colitis.

AIMS: HBsAg loss with anti-HBs acquisition is considered a functional cure and ideal treatment goal for patients with CHB. Our group have reported the efficacy of therapeutic vaccine with HBsAg and HBcAg (NASVAC) by intranasal and subcutaneous injection. In this study, we investigated the safety and efficacy of newly developed CVP-NASVAC, which contained NASVAC with mucoadhesive carboxyl vinyl polymer (CVP) in the dedicated device. METHODS: A single dose, open-label, phase IIa clinical trial of CVP-NASVAC was conducted. Patients with CHB treated with nucleoside/nucleotide analogs (NAs) and HBV carriers not undergoing anti-HBV treatment were enrolled. CVP-NASVAC was injected through the nose for, in total, 10 times. Participants were followed-up for 18 months, and their HBsAg reduction and anti-HBs induction assessed as endpoints. RESULTS: Among the patients with CHB treated with NAs (n = 27) and HBV carriers without NAs (n = 36), 74.1% and 75.0% exhibited reductions in their baseline HBsAg, and the mean reductions were -0.1454 log10  IU/ml (p < 0.05) and -0.2677 log10  IU/ml (p < 0.05), respectively. Anti-HBs antibody was detected in 40.7% and 58.3% of patients treated with and without NAs, respectively. Six of 71 (9.5%) patients were functionally cured after the CVP-NASVAC treatment. CONCLUSIONS: Anti-HBs induction and HBsAg reduction was observed after CVP-NASVAC treatment in some patients with CHB. The CVP-NASVAC is a safe treatment, which might expect to achieve functional cure for patients with CHB.

PURPOSE: The association between body mass index (BMI) and irritable bowel syndrome (IBS) has been inconsistent in the Asian population. Also, no evidence regarding this issue in the young population exists. The aim of the present study is to investigate the association between BMI and IBS based on the Rome III criteria in young Japanese people. METHODS: This study was a cross-sectional study consisted of 8923 Japanese university students. The definition of IBS was based on the Rome III criteria. BMI was divided into four categories (quartiles) on the basis of the study subjects' distribution (lowest, low, moderate, and high [reference]). The definition of lean, normal, and overweight was BMI < 18.5 kg/m2, 18.5 ≤ BMI < 25 kg/m2 (reference), and 25 ≤ BMI kg/m2, respectively. Age, sex, drinking, smoking, exercise habit, anemia, and sports injury were selected a priori as potential confounding factors. RESULTS: The prevalence of IBS was 6.5%, with females having a significantly higher prevalence than males (6.0% vs. 7.2%, p = 0.029). In females, being overweight was independently positively associated with IBS after adjustment (adjusted odds ratio [OR]: 1.81 [95% confidence interval (CI): 1.13-2.79]). In contrast, in males, no association between being lean or overweight and IBS was found. CONCLUSIONS: Among the young Japanese population, being overweight might be independently positively associated with prevalence of IBS in females but not in males.

The relationship between advanced nonalcoholic steatohepatitis (NASH) and plasma fatty acid composition remains unknown. We aimed to examine the plasma fatty acid composition in biopsy-confirmed nonalcoholic fatty liver disease (NAFLD) and evaluate the relationship between histological findings and fatty acid composition. Overall, 235 patients (134 women) with NAFLD were enrolled. Comprehensive blood chemistry tests and histological examinations of liver samples were conducted. Multivariate analyses adjusted for age, sex, body mass index, alanine aminotransferase, hemoglobin A1c, creatinine, total cholesterol, triglyceride, and NAFLD Activity Score values showed that lower levels of arachidic, behenic, α-linolenic, eicosatetraenoic, docosapentaenoic, and docosahexaenoic acids and higher levels of mead acid were associated with fibrosis stage 3-4. Furthermore, higher lauric acid, myristic acid, and palmitic acid levels and monounsaturated fatty acids such as palmitoleic acid and oleic acid were significantly associated with high NAS in analyses adjusted for the same factors and fibrosis stage. The plasma fatty acid composition was associated with the histological evidence of NASH. Increased synthesis of fatty acids is associated with NASH; insufficient intake of n-3 essential fatty acids and reduced elongation of fatty acids are associated with fibrosis in NASH. These features may help clinicians to understand and treat advanced NASH cases.

OBJECTIVE: Socioeconomic status is a risk factor for worse outcomes in many diseases. However, evidence on the association between socioeconomic status and clinical outcome in patients with ulcerative colitis (UC) is limited. In the clinical setting, the therapeutic goal for UC is to achieve mucosal healing (MH). Thus, the aim of this study is to examine the association between socioeconomic status and MH in patients with UC. METHODS: The study population consisted of 298 patients with UC. Education status and household income were divided into three groups based on a self-administered questionnaire. MH and complete MH were defined as a Mayo endoscopic subscore of 0-1 and 0, respectively. The association of socioeconomic status with MH and complete MH was assessed by multivariate logistic regression analysis. Patients with UC were divided into a younger group (<51 years old) and an older group (≥51 years old) based on median age. RESULTS: The percentage of MH and complete MH was 62.4% and 25.2%, respectively. In all patients, socioeconomic status was not associated with MH and complete MH, respectively. In the older group, education but not household income was independently positively associated with MH and complete MH. In contrast, in the younger group, no association between socioeconomic status and MH and complete MH was found. CONCLUSION: In older Japanese patients with UC, education status but not household income was independently positively associated with MH and complete MH.

Background/Aims: Functional dyspepsia (FD) may be a common digestive disease worldwide and reduces the quality of life of patients. However, only a few studies have investigated the association between eating behavior and FD. The purpose of this cross-sectional study is to examine the association between eating behavior and prevalence of FD in a young Japanese cohort. Methods: In this study, we enrolled 8923 Japanese university students. FD is diagnosed based on the Rome III criteria. Eating habits and frequency of meals were investigated using a self-administered questionnaire. Results: The FD subjects had a younger mean age, a lower body mass index, and a lower proportion of men compared to the non-FD subjects. An independent positive association between skipping breakfast and/or lunch and FD was found (adjusted ORs were 1.60 [95% CI, 1.10-2.32] for breakfast and 2.52 [95% CI, 1.04-5.18] for lunch). Skipping dinner, extra meals (snacks) or midnight snacks was not associated with FD. The prevalence of FD in subjects eating 1, 2, and 3 meals per day was 4.8%, 2.2%, and 1.7%, respectively. The frequency of meals was independently inversely associated with prevalence of FD (adjusted ORs were 1 per day: 2.72 [95% CI, 1.19-5.42], and 2 per day: 1.69 [95% CI, 1.16-2.43], P for trend = 0.001). Conclusions: In the young Japanese people, the frequency of meals may be independently inversely associated with prevalence of FD. In particular, skipping breakfast and/or lunch was associated with the prevalence of FD.

BACKGROUND: The interleukin (IL)-23/Th17 pathway plays a critical role in ulcerative colitis (UC). The IL-12p40 subunit, which is shared by IL-23 and IL-12, is encoded by the IL12B gene. The current case-control study investigated the association between IL12B SNP rs6887695 and the UC risk. METHODS: There were 384 cases within 4 years of UC diagnosis and 661 controls who were enrolled. Adjustments were made for sex, age, pack-years of smoking, alcohol consumption, history of appendicitis, family history of UC, education level, and body mass index. RESULTS: Subjects with the GG IL12B SNP rs6887695 genotype had a significantly increased risk of UC compared with those with the CC genotype (adjusted odds ratio [AOR], 1.60; 95% confidence interval [CI], 1.08-2.36). This positive association was also significant using the additive and recessive models (AOR, 1.25; 95% CI, 1.03-1.52; AOR, 1.50; 95% CI, 1.08-2.09, respectively). An independent inverse relationship was observed between ever alcohol consumption and the UC risk in those with the CC genotype while no significant association was found in those with at least one G allele (P for interaction = 0.0008). CONCLUSIONS: IL12B SNP rs6887695 was significantly associated with UC. The influence of alcohol consumption might rely on rs6887695.

OBJECTIVES: This retrospective analysis of patients treated with endoscopic endonasal transsphenoidal surgery (ETSS) alone or simultaneous combined surgery investigated imaging features suitable for surgical methods and pitfalls in simultaneous combined surgery for giant pituitary adenoma. PATIENTS AND METHODS: Ten patients with giant pituitary adenoma treated by ETSS alone or simultaneous combined endoscopic endonasal and transcranial surgery were enrolled. By analyzing tumor imaging features on magnetic resonance imaging (MRI), operative findings and clinical outcomes, we examined types of imaging features suitable for each surgical method. RESULTS: Four patients received ETSS alone and six patients underwent simultaneous combined endonasal and transcranial surgery. Four patients treated by ETSS alone and three patients treated by combined surgery had high resection rates and good outcomes. The remaining three patients with combined surgery achieved partial resection and visual deterioration in one patient. MRI features suitable for ETSS included an enlarged sella, upward tumor extension, and round surface, whereas those for combined surgery included normal/enlarged sella, anterior and/or unilateral tumor extension, and a multilobulated surface. Tumors extending extensively bilaterally or upward and encasing neurovascular structures could not be effectively resected even under combined surgery. CONCLUSION: Both ETSS alone and simultaneous combined endonasal and transcranial surgery showed good results for giant pituitary adenoma when the surgical methods matched suitable imaging features. Tumors with unilateral or anterior extension and a multilobulated surface were maximally resected without neurological deficit by combined surgery, but tumors showing extensive multi-directional extension and full encasement of neurovascular structures were not effectively resected even with combined surgery.

The potential health benefits of laughter are recognized in relation to several chronic diseases. However, no study has yet investigated the association between laughter and functional dyspepsia (FD). The purpose of this study was to investigate this issue in a young Japanese population. METHODS: This study was conducted on 8923 Japanese university students. Information on the frequency of laughter and types of laughter-inducing situations, digestive symptoms (Rome III criteria) were obtained through a self-administered, web-based questionnaire. RESULTS: The percentage of respondents who laughed out loud almost every day was 64.3%. On the other hand, 1.8% of the subjects reported that they rarely laughed. No association was found between the total frequency of laughter and FD. Laughing while talking with family and friends almost every day was significantly inversely associated with FD (adjusted odds ratio (OR): 0.47 (95% confidence interval (CI): 0.28-0.81); p for trend was 0.003). On the other hand, laughing while watching TV or videos and laughing while looking at comics or magazines independently showed a positive correlation with FD (TV or videos: adjusted OR, 1-5 times a week: 1.74 (95% CI: 1.16-2.60); comics or magazines: adjusted OR, 1-5 times a week: 1.78 (95% CI: 1.08-2.81)). CONCLUSION: In this young Japanese population, no association between laughter frequency and FD was observed although laughing while talking with friends and family was independently and inversely associated with FD.

INTRODUCTION: Luseogliflozin is a sodium-glucose cotransporter 2 (SGLT2) inhibitor. Unhealthy eating behavior is associated with diabetes, hypertension, and obesity. However, evidence regarding the effect of medications, including SGLT2 inhibitors, on unhealthy eating behavior is limited. This study investigated the association between unhealthy eating behavior and the laboratory and physical findings of Japanese patients with type 2 diabetes given luseogliflozin once daily for 24 weeks. METHODS: Twenty-nine patients with type 2 diabetes mellitus were enrolled in a 24-week prospective, open-label, single-arm pilot study. The information regarding unhealthy eating behaviors (eating fast, late dinner, nighttime snack, skipping breakfast, and eating until full) was obtained using self-reported questionnaires. RESULTS: The baseline rate of eating fast, late dinner, nighttime snack, skipping breakfast, and eating until full was 51.7%, 24.1%, 24.1%, 10.3% and 55.2%, respectively. After administration of luseogliflozin, fasting plasma glucose, HbA1c, aspartate aminotransferase (ALT), weight, body mass index, and waist measurement all decreased significantly. High-density lipoprotein cholesterol and hematocrit increased significantly. In the healthy eating behavior group, the improvements of fasting plasma glucose and ALT, but not other variables, were attenuated. HbA1c level was significantly improved in patients with eating fast, while other unhealthy eating behaviors attenuated the effect of luseogliflozin for HbA1c. The effect of leseogliflozin on the relationship between eating behavior and weight reduction was inconsistent after administration luseogliflozin. CONCLUSION: Luseogliflozin might be more effective for controlling plasma glucose in patients with type 2 diabetes who have a tendency to eat fast, but it might have less effect on those with other unhealthy eating habits.

AIMS: To investigate whether fibrosis-4 index can help stratify the risk of diabetes mellitus in subjects with fatty liver disease. METHODS: Based on fatty liver disease and fibrosis-4 index (cutoff value, 1.3), we retrospectively divided 9,449 subjects, who underwent at least two annual health checkups, into four groups stratified by gender: normal, high fibrosis-4 indexwithout fatty liver disease, low fibrosis-4 index with fatty liver disease, and high fibrosis-4 index with fatty liver disease groups. RESULTS: Onset rates for diabetes mellitus in the normal, high fibrosis-4 index without fatty liver disease, low fibrosis-4 index with fatty liver disease, and high fibrosis-4 index with fatty liver disease groups were 1.6%, 4.3%, 6.8%, and 10.2%, respectively, in men, and 0.6%, 0.9%, 5.3%, and 7.0%, respectively, in women. Compared with the normal group, the high fibrosis-4 index without fatty liver disease, low fibrosis-4 index with fatty liver disease, and high fibrosis-4 index with fatty liver disease groups were at a significant risk for diabetes mellitus onset in both male and female subjects. Moreover, in both genders, high fibrosis-4 index with fatty liver disease remained a significant risk factor on multivariate analysis (high fibrosis-4 index with fatty liver disease group: adjusted harzard ratio, 95% confidence interval: 4.03, 2.19-7.42 [men] and 6.40, 1.77-23.14 [women]). CONCLUSIONS: Subjects with fatty liver disease and high fibrosis-4 index had a higher risk of diabetes mellitus onset. Therefore, fibrosis-4 index can help stratify the risk of diabetes mellitus in patients with fatty liver disease and identify patients requiring intervention.

Purpose: The albumin-to-globulin ratio (AGR) is a recognized chronic inflammation marker. No evidence regarding the relationship between AGR level and ulcerative colitis (UC) exists. The aim of this study was to evaluate the association between AGR and clinical outcomes among Japanese subjects with UC. Methods: The study subjects consisted of 273 Japanese individuals with UC. AGR was divided into 4 categories (low, moderate, high, and very high). The definition of complete mucosal healing (MH) was based on the Mayo endoscopic subscore of 0. Clinical remission (CR) was defined as no rectal bleeding and no abnormally high stool frequency (<3 times per day). Results: The percentage of MH was 26.4%. High AGR and very high AGR were significantly positively correlated with CR (adjusted odds ratio [OR], 5.85; 95% confidence interval [CI], 2.52-14.18 and adjusted OR, 4.97; 95% CI, 2.14-12.04) and complete MH (adjusted OR, 4.03; 95% CI, 1.56-11.51 and adjusted OR, 5.22; 95% CI, 1.97-14.89), respectively after adjustment for confounding factors (P for trend=0.001). Only in the low C-reactive protein (CRP) group (≤0.1 mg/dL), very high AGR was significantly positively correlated with complete MH but not CR (adjusted OR, 4.38; 95% CI, 1.06-21.77; P for trend=0.017). In the high CRP group, no correlation between AGR and complete MH was found. Conclusion: Among Japanese patients with UC, AGR may be independently positively correlated with complete MH. In particular, among UC patients with low CRP, AGR might be a useful complementary marker for complete MH.

INTRODUCTION: Untreated nonalcoholic fatty liver may progress to nonalcoholic steatohepatitis (NASH) and cirrhosis and induce hepatocellular carcinoma and liver failure. Type 2 diabetes mellitus (T2DM), often complicated with nonalcoholic fatty liver disease (NAFLD), is a driver of NAFLD progression. Thus, efficacious treatment strategies for patients with coexisting NAFLD and T2DM are important for preventing NAFLD progression. Although previous studies have demonstrated that either sodium-glucose transporter 2 inhibitors (SGLT2is) or glucagon-like peptide 1 receptor agonists (GLP-1 RAs) benefit NASH patients with T2DM, the rate of NASH resolution has not sufficiently improved. Therefore, we developed a protocol for a randomized controlled trial to examine whether the addition of an SGLT2i to the treatment regimen of patients receving a GLP-1 RA (combination therapy), within the therapeutic dose range for T2DM, increases the rate of NASH resolution in patients with coexisting NASH and T2DM. METHODS: This open-label, randomized, parallel-group study commenced in June 2021, will conclude recruitment in May 2023, and will end by March 2025. Sixty patients with NASH complicated by T2DM are enrolled at the Ehime University Hospital in Toon, Japan. Participants will be randomized into: (1) an intervention group receiving combination therapy with the SGLT2i luseogliflozin 2.5 mg, once daily (Taisho Pharmaceutical, Tokyo, Japan) and the GLP-1 RA semaglutide 0.5 mg, once per week (Novonordisk, Copenhagen, Denmark); and (2) a control group receiving monotherapy with the GLP-1 analog semaglutide. The primary endpoints, which will be ascertained by liver biopsy, are: (1) NASH resolution rate from baseline without worsening of liver fibrosis after 52 weeks of intervention; (2) rate of improvement from baseline of at least 1 point in the NAFLD activity score without worsening of liver fibrosis after 52 weeks of intervention; and (3) rate of improvement from baseline of at least one fibrosis stage without worsening of NASH after 52 weeks of intervention. TRIAL REGISTRATION: University Hospital Medical Information Network Clinical Trial Registry (UMIN-CTR) number: UMIN000045003. Japan Registry of Clinical Trials registration number: jRCTs061210009.

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) is diagnosed after excluding other liver diseases. The pathogenesis of NAFLD when complicated by other liver diseases has not been established completely. Metabolic dysfunction-associated fatty liver disease (MAFLD) involves more metabolic factors than NAFLD, regardless of complications with other diseases. This study aimed to clarify the effects of fatty liver occurring with metabolic disorders, such as MAFLD without diabetes mellitus (DM), on the development of DM. MATERIALS AND METHODS: We retrospectively assessed 9,459 participants who underwent two or more annual health check-ups. The participants were divided into the MAFLD group (fatty liver disease with overweight/obesity or non-overweight/obesity complicated by metabolic disorders), simple fatty liver group (fatty liver disease other than MAFLD group), metabolic disorder group (metabolic disorder without fatty liver disease), and normal group (all other participants). RESULTS: The DM onset rates in the normal, simple fatty liver, metabolic disorder, and MAFLD groups were 0.51, 1.85, 2.52, and 7.36%, respectively. In the multivariate analysis, the MAFLD group showed a significantly higher risk of DM onset compared with other three groups (P < 0.01). Additionally, the risk of DM onset was significantly increased in fatty liver disease with overweight/obesity or pre-diabetes (P < 0.01). CONCLUSIONS: Fatty liver with metabolic disorders, such as MAFLD, can be used to identify patients with fatty liver disease who are at high risk of developing DM. Additionally, patients with fatty liver disease complicated with overweight/obesity or prediabetes are at an increased risk of DM onset and should receive more attention.

BACKGROUND: A simple serum biomarker for clinical outcome in patients with ulcerative colitis (UC) remains an unmet need. Some studies have shown an association between C-reactive protein (CRP)-albumin ratio (CAR) and prognosis in patients with inflammatory bowel disease (IBD), but evidence regarding the association between CAR and UC remains limited. We evaluated the association between CAR and clinical outcome in Japanese patients with UC. METHODS: Subjects were 273 Japanese patients with UC. Clinical remission was defined as absence of both abnormally high stool frequency (< 3 per day) and rectal bleeding. Mucosal healing (MH) was defined as Mayo endoscopic subscore (MES) 0. Moderate to severe endoscopic activity was defined as MES 2-3. Subjects were divided according to CAR into tertiles (low, moderate, and high). RESULTS: The proportions of patients with clinical remission, MH, and moderate to severe endoscopic activity were 57.9%, 26.0%, and 37.0%, respectively. High CAR was significantly positively associated with moderate to severe endoscopic activity but not MH or clinical remission after adjustment (adjusted odds ratio [OR] 2.18 [95% confidence interval (CI) (1.11-4.35)], p for trend 0.023), but only in patients with long disease duration (> 7 years) (adjusted OR 2.95 [95% CI (1.06-8.79)], p for trend 0.023). CAR was not associated with clinical remission or MH. CONCLUSIONS: CAR may be significantly positively associated with moderate to severe endoscopic activity but not clinical remission or MH in Japanese patients with UC. In patients with long UC duration, CAR might be a useful serum marker for disease activity.

BACKGROUND: Functional dyspepsia (FD) is a very common disease worldwide. Dysmenorrhea impairs quality of life among females of reproductive age. Although dysmenorrhea is associated with irritable bowel syndrome (IBS), no study has yet evaluated the association between dysmenorrhea and FD. METHODS: This study's subjects consisted of 4693 female Japanese university students. We defined FD according to the Rome III criteria. Subjects completed a self-reported questionnaire regarding menstrual irregularity, menstrual pain, and medication for menstrual pain. Age, body mass index, drinking, smoking, exercise habit, anemia, and first-year student status were selected as potential confounding factors. RESULTS: The prevalence of FD, epigastric pain syndrome (EPS), and postprandial distress syndrome (PDS) was 2.5%, 0.6%, and 2.1%, respectively. Heavy menstrual pain was independently positively associated with FD and PDS but not EPS (adjusted ORs: FD, 3.18 [95% CI: 1.60-6.89] and PDS, 2.93 [95% CI: 1.56-7.93] for heavy menstrual pain, p for trend = 0.001 and 0.004, respectively). Using medication for menstrual pain often was independently positively associated with FD, EPS, and PDS, respectively, (adjusted ORs: FD, 2.41 [95% CI: 1.50-3.83], EPS, 2.93 [95% CI: 1.04-7.93], PDS, 2.44 [95% CI: 1.46-4.01]). Irregular menstrual cycle was not associated with FD or with subtype of FD. CONCLUSION: Among the young female Japanese population, menstrual pain might be independently positively associated with FD and PDS but not EPS. The use of medication for menstrual pain might be independently positively associated with FD including subtype of FD.

BACKGROUND AND AIM: Although an inverse relationship between current smoking and the development of ulcerative colitis (UC) has been shown in North America and Europe, evidence is limited in Asian countries, where the incidence of UC is rapidly increasing. This Japanese case-control study examined the association between active and passive smoking and risk of UC. METHODS: A self-administered questionnaire was used to obtain information on smoking and potential confounding factors in 384 cases with a diagnosis of UC within the past 4 years and 665 controls. RESULTS: Compared with having never smoked, having ever smoked was associated with an increased risk of UC (adjusted odds ratio [OR] = 1.70, 95% confidence interval [CI]: 1.23-2.37). No association was observed between current smoking and risk of UC, but former smokers had a significant elevation in risk (adjusted OR = 2.40, 95% CI: 1.67-3.45). There was a positive dose-response relationship with pack-years smoked (P for trend = 0.006). Among never smokers, passive smoking exposure at home was significantly associated with an increased risk of UC (adjusted OR = 1.90, 95% CI: 1.30-2.79). A significant dose-response gradient was also observed between pack-years of passive smoking at home and risk of UC (P for trend = 0.0003). CONCLUSIONS: We confirmed that former smoking elevated the risk of UC, whereas an inverse association between current smoking and the risk of UC did not reach a statistically significant level. Passive smoking may be associated with an increased risk of UC.

INTRODUCTION: Monocytes play an important role in innate immunity. Some epidemiological evidence indicates an association between peripheral blood monocytes and ulcerative colitis (UC). The association between peripheral blood monocytes and mucosal healing (MH), however, remains unclear. We evaluated this issue in patients with UC. METHODS: Study subjects consisted of 272 Japanese patients with UC. Monocyte counts were taken in the morning after overnight fasting. Monocyte count was divided into tertiles based on the distribution of values among all study subjects. Information on clinical remission was obtained from medical records. MH was assessed using the Mayo endoscopic subscore. RESULTS: The mean monocyte count was 360.1 ± 155.3/mm3. Rates of clinical remission, MH, and complete MH were 61.0%, 66.2%, and 27.9%, respectively. High monocyte count was significantly inversely associated with clinical remission, MH, and complete MH (adjusted odds ratio [OR] 0.45 [95% confidence interval [CI]: 0.23-0.89], OR 0.45 [95% CI: 0.23-0.89], and OR 0.48 [95% CI: 0.23-0.97], respectively). Patients were also classified according to C-reactive protein (CRP) levels; in the low CRP group (<0.1 mg/dL), high monocyte count was independently inversely associated with complete MH but not with clinical remission or MH (OR 0.33 [95% CI: 0.10-0.92], P for trend = 0.027). In the high CRP group, there was no association between monocyte count and clinical outcomes. DISCUSSION: Our findings suggest that peripheral blood monocyte count can be used as a serum supplemental marker for MH in UC patients with low CRP levels.

OBJECTIVES: Oxidative stress is considered one of the etiologic factors involved in ulcerative colitis (UC), yet there is limited epidemiologic information regarding the relationship between antioxidant intake and the risk of UC. The aim of the present case-control study in Japan was to examine the association between intake of green and yellow vegetables, other vegetables, fruit, vitamin C, vitamin E, retinol, alpha-carotene, beta-carotene, and cryptoxanthin and UC risk. METHODS: A total of 384 cases within 4 y of diagnosis with UC and 665 controls were included in the study. Data on dietary intake and confounders were obtained using a self-reported questionnaire. Information on dietary factors was collected using a 169-item semiquantitative food-frequency questionnaire. Adjustment was made for sex, age, pack-y of smoking, alcohol consumption, history of appendicitis, family history of UC, education level, and body mass index. RESULTS: Higher intake levels of other vegetables, vitamin C, and retinol were independently associated with a reduced risk of UC. The adjusted odds ratio between extreme quartiles was 0.51 (95% confidence interval [CI], 0.34-0.76; P for trend ≤ 0.001) for other vegetables, 0.45 (95% CI, 0.30-0.69, P for trend ≤ 0.001) for vitamin C, and 0.64 (95% CI, 0.43-0.95, P for trend = 0.04) for retinol. There were no associations between intake of green and yellow vegetables, fruit, vitamin E, alpha-carotene, beta-carotene, or cryptoxanthin and UC risk (P for trend = 0.29, 0.56, 0.89, 0.20, 0.69, and 0.22, respectively). CONCLUSIONS: Intake of other vegetables, vitamin C, and retinol was inversely associated with UC risk.

ABSTRACT: Most patients with pancreatic cancer are ineligible for curative resection at diagnosis, resulting in poor prognosis. This study aimed to evaluate the prognostic factors in patients with unresectable pancreatic cancer.We retrospectively collected clinical data from 196 patients with unresectable pancreatic cancer who received palliative chemotherapy (N = 153) or palliative care alone (N = 43) from January 2011 to December 2013. Patients' background data and overall survival were analyzed using the Cox proportional hazard regression model.In patients receiving palliative chemotherapy (gemcitabine-based regimen, 88.2%) and palliative care alone, the median (range) ages were 68 (43-91) and 78 (53-90) years, and metastatic diseases were present in 80% (N = 123) and 86% (N = 37), respectively. Multivariate analysis in the palliative chemotherapy patients showed that liver metastasis (hazard ratio [HR] 2.25, 95% confidence interval [CI] 1.58-3.20, P < .001), neutrophil-to-lymphocyte ratio (>4.5 vs ≤4.5; HR 3.45, 95% CI 2.22-5.36, P < .001), and cancer antigen 19-9 (CA19-9) (≥900 vs <900 U/mL; HR 1.45, 95% CI 1.02-2.05, P = .036) were independent prognostic factors. In those receiving palliative care alone, lung (HR 3.27, 95% Cl 1.46-7.35, p = 0.004) and peritoneum (HR 2.50, 95% CI 1.20-5.18, P = .014) metastases and the C-reactive protein-to-albumin ratio (≥1.3 vs <1.3; HR 3.33, 95% Cl 1.51-7.35, P = .003) were independent prognostic factors. Furthermore, patients with multiple factors had worse prognosis in both groups. Median survival time of palliative chemotherapy patients with risk factors 0, 1, 2, and 3 were 13.1 (95% CI 8.0-16.9), 9.4 (95% CI 7.9-10.1), 6.6 (95% CI 4.9-7.8), and 2.5 (95% CI 1.7-4.0) months, respectively. Similarly, median survival time was 5.7 (95% CI 1.3 -8.0), 2.1 (95% CI 1.5-3.9), and 1.3 (95% CI 0.6-1.7) months, respectively, for palliative care alone patients with risk factor 0, 1, and 2 to 3.Prognostic markers for pancreatic cancer were neutrophil-to-lymphocyte ratio, liver metastasis, and CA19-9 in patients undergoing palliative chemotherapy and C-reactive protein-to-albumin ratio and lung/peritoneum metastases in patients undergoing palliative care alone. These simple markers should be considered when explaining the prognosis and therapeutic options to patients.

BACKGROUND: Evidence regarding the association between sleep disturbance and functional dyspepsia (FD) remains limited in the young population. AIMS: This study aimed to investigate the association between sleep disturbance and FD including subgroups among Japanese young people. METHODS: Study subjects were 8923 university students. FD was defined according to the Rome III criteria. Subjects with FD were further categorized as having postprandial distress syndrome (PDS) or epigastric pain syndrome (EPS). Subjects completed a self-reported questionnaire assessing self-reported sleep duration, sleep disturbance, difficulty falling asleep, deep sleep disorder, nocturnal awakening, early awakening, and daytime sleepiness. RESULTS: The prevalence of FD was 1.9%. After adjustment, all types of sleep disturbances were independently positively associated with FD (total sleep disturbance: OR 4.11 [95% CI: 2.89-5.78], difficulty falling asleep: OR 3.97 [95% CI: 2.53-6.01], deep sleep disorder: OR 4.85 [95% CI: 3.06-7.40], nocturnal awakening: OR 4.35 [95% CI: 1.90-8.67], early awakening: OR 4.50 [95% CI: 1.97-8.97], and daytime sleepiness: OR 2.83 [95% CI: 1.25-5.56]). While nocturnal awakening and daytime sleepiness were not associated with EPS, the other types of sleep disturbance were independently positively associated with EPS and PDS. No association between self-reported sleep duration and FD was found. CONCLUSIONS: Sleep disturbance may be independently positively associated with the prevalence of FD among Japanese young people. Nocturnal awakening and daytime sleepiness were not associated with EPS; the other types of sleep disturbance were independently positively associated with EPS and PDS.

INTRODUCTION: Fatty liver disease (FLD) is a surrogate condition for glucose intolerance development. FLD may involve normal or abnormal liver enzyme levels. Whether FLD is a risk factor for glucose intolerance, regardless of liver enzyme levels, remains unknown. We assessed relationships between the development of impaired fasting glucose (IFG) and FLD, liver enzyme abnormalities, and alcohol consumption. MATERIALS AND METHODS: We retrospectively evaluated 8,664 participants with more than two annual health check-ups. Participants were classified according to sex, alcohol consumption, alanine aminotransferase (ALT) levels, and fatty liver status. RESULTS: In univariate analyses, IFG onset among men was related to normal or high ALT levels with FLD in the nonalcoholic and alcoholic groups (P-trend < 0.01). In multivariate analyses, IFG onset among nonalcoholic men was associated with normal or high ALT levels with FLD, independent of potential confounding factors (P-trend < 0.01). However, IFG onset was non-independently associated with any condition among alcoholic men. In univariate analyses, IFG onset among women was related to normal or high ALT levels with FLD in the nonalcoholic group (P-trend < 0.01) and high ALT levels with FLD in the alcoholic group (P-trend < 0.05). In multivariate analyses, IFG onset was independently associated with only normal ALT levels in nonalcoholic FLD women. CONCLUSIONS: Among nonalcoholic men and women, FLD was a risk factor for IFG onset, including normal ALT concentrations. Care is needed for individuals with nonalcoholic FLD, regardless of liver injury, possibly helping reduce glucose intolerance risk.

BACKGROUND: Causes of non-alcoholic fatty liver disease and its progression include visceral fat accumulation and loss of muscle mass; however, which of the two phenomena is more critical is unclear. Therefore, we intended to examine the relationship between body composition and non-alcoholic fatty liver disease progression as indicated by fibrosis and the non-alcoholic fatty liver disease activity score. METHODS: This cross-sectional study comprised 149 patients (55 men; age, 20-76 years) treated for non-alcoholic fatty liver disease between December 2010 and January 2020. Body composition measurements, histological examinations of liver samples, and comprehensive blood chemistry tests were performed. The relationship between body composition and non-alcoholic fatty liver disease histology findings was analyzed using the logistic regression model. RESULTS: Fibrosis was significantly and inversely correlated with muscle mass and appendicular skeletal muscle mass and significantly and positively correlated with fat mass, fat mass/height squared, visceral fat area, and waist-hip ratio (P < 0.05). After adjustment for sex, blood chemistry measurements, and body composition indices, fibrosis remained associated with appendicular skeletal muscle mass, fat mass, fat mass/height squared, and visceral fat area (P < 0.05). Non-alcoholic fatty liver disease activity score ≥ 5 significantly correlated with fat mass and fat mass/height squared in a univariate but not multivariate analysis. CONCLUSIONS: Fibrosis in non-alcoholic fatty liver disease, an indicator of unfavorable long-term outcomes, is associated with more indices of fat mass than of those of muscle mass. Hence, fat mass should be controlled to prevent non-alcoholic fatty liver disease progression.

Hyperammonemia is an important stimulator of myostatin expression, a negative regulator of muscle growth. After splenectomy or partial splenic artery embolization (PSE), hyperammonemia often improves. Thus, we investigated changes in skeletal muscle index (SMI) in patients following an operation on the spleen and in patients who did not undergo an operation on their spleen. The study was designed retrospectively, in which we analyzed data collected between January 2000 and December 2015. Patients were assigned to the splenectomy/PSE or nontreatment group. Changes in SMI (ΔSMI), ammonia (Δammonia), myostatin (Δmyostatin), irisin (Δirisin), and branched-chain amino acids/tyrosine molar ratio (ΔBTR) were analyzed between baseline and 5-year follow-up both before and after inverse probability of treatment weighting adjustment (IPTW). Patients (102) were enrolled (splenectomy/PSE, n = 45; nontreatment group, n = 57) before IPTW adjustment: ΔSMI (2.6 cm2/m2 vs. -8.8 cm2/m2, respectively) (P < 0.001), Δmyostatin (-867 vs. -568, respectively) (P < 0.001), Δammonia (-34 and 16, respectively) (P < 0.001), and ΔBTR (0.89 and -0.665, respectively) (P < 0.001). There were no differences between splenectomy and PSE regarding these factors. Moreover, after IPTW adjustment, significant differences were observed between the splenectomy/PSE and nontreatment group for the median ΔBTR (0.89 and -0.64, respectively) (P < 0.001), Δammonia (-33 and 16, respectively) (P < 0.001), Δmyostatin (-894 and 504, respectively) (P < 0.001), and ΔSMI (1.8 cm2/m2 and -8.2 cm2/m2, respectively) (P < 0.001). Conclusions: Both splenectomy and PSE were associated with the prevention of secondary sarcopenia in patients with LC. Moreover, it can be expected that muscle volume loss is reduced by splenectomy or PSE in patients with hyperammonemia.

Objective: To determine whether severe kyphosis is one of the risk factors of umbilical trichophytosis in elderly people. Patients and Methods: Four cases with umbilical trichophytosis in the last 3 years and all 143 patients who visited to our clinic during from April 2018 to March 2019 were included in this study. The relationship between the condition of umbilical region and kyphosis was investigated. As regards the levels of senile kyphosis, simple visual classification of the kyphosis method was used (Level 0-4). Results: All four cases with umbilical trichophytosis were elderly women aged ≥80 years, had severe kyphosis, skin overlaps, filthy umbilical region, and lumps of dirt in the umbilical region and had nail tinea. Only two cases had umbilical trichophytosis among 143 patients who visited our clinic during the 1 year study period, with incidence is of 1.4%/year. About 65.7%, 60%, and 37.1% of 35 patients with kyphosis with forward-bent posture had skin overlap, moist, and filthy umbilical regions, respectively. However, these symptoms were not found in patients without severe kyphosis. Conclusion: Severe kyphosis with forward-bent posture could be one of the risk factors of umbilical trichophytosis in elderly people.

BACKGROUND AND AIMS: Lipoprotein(a) [Lp(a)] is an important independent cardiovascular risk factor. However, Lp(a) levels are lower in patients with chronic liver disease than in healthy subjects. Furthermore, Lp(a) levels decrease as residual liver function declines. Although non-alcoholic fatty liver disease (NAFLD), especially advanced non-alcoholic steatohepatitis (NASH), increases the risk of cardiovascular diseases, the relationship between serum Lp(a) level and NASH is unknown. Thus, we examined the relationship between serum Lp(a) levels and biopsy-proved NAFLD and clarified the significance of Lp(a) measurements for cardiovascular disease screening in patients with NAFLD. METHODS: A total of 176 patients with NAFLD were enrolled. Comprehensive blood chemistry tests and histological examinations of liver samples were conducted. The relationship between serum Lp(a) levels and NAFLD was analyzed. RESULTS: Serum Lp(a) levels in advanced fibrosis (stage 3-4) were lower than those in non-advanced fibrosis (stage 0-2) (p < 0.05). After adjustment for age, sex, body mass index, alanine aminotransferase (ALT), creatinine (Cre), HbA1c level, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and the use of lipid-lowering agents, the significant inverse association between advanced fibrosis and serum Lp(a) levels remained (p < 0.01). Although the Lp(a) level was inversely associated with an NAFLD Activity Score (NAS) of 5-8, there was no significant association between Lp(a) levels and NAS adjusted for age, sex, body mass index, ALT, Cre, HbA1c level, HDL-C, LDL-C, TG, and the use of lipid-lowering agents. CONCLUSIONS: Advanced NASH is associated with low serum Lp(a) levels; therefore, Lp(a) levels may not be useful in evaluating cardiovascular risk.

Objective The long-term effect of the ABO blood type on the clinical course of patients with pancreatic cancer (PC) is inconclusive. This study aimed to determine whether or not the ABO blood type influences the long-term outcomes of PC in Japanese patients. Methods The medical records of Japanese patients with PC were reviewed. Data, including the age, sex, and outcomes, from the Ehime Pancreato-Cholangiology Study Group were analyzed. Results The mean age of the 406 patients was 71.0±10.5 years, and 220 (54.2%) were men. A total of 44.6%, 20.7%, 22.4%, and 12.3% had blood type A, B, O, and AB, respectively. The median survival time (MST) of patients with A alleles was shorter than that of patients with non-A alleles (p=0.048), especially among those who underwent resection (p=0.031). In contrast, no marked difference in the MST was noted among those who underwent chemotherapy and palliative care. Finally, a multivariate analysis confirmed A alleles as an independent factor associated with the long-term outcome of PC (p<0.05 in 2 different models). Conclusion The ABO blood type influenced the long-term outcomes of Japanese patients with PC, presumably due to its impact on disease onset and tumor behavior.

OBJECTIVE: To evaluate whether patients with hepatitis B virus (HBV)- and hepatitis C virus (HCV)-related chronic liver disease were diagnosed as having pancreatic cancer (PC) at an early stage during abdominal imaging surveillance for hepatocellular carcinoma (HCC). PATIENTS AND METHODS: We retrospectively examined 447 patients with PC diagnosed at Ehime University Hospital and affiliated centers (2011-2013). Data were collected regarding HBV and HCV status, likelihood of PC diagnosis, and Union for International Cancer Control (UICC) stage. Intergroup comparisons were performed using the χ2 test. RESULTS: The UICC stage distribution in the HCC surveillance group (n=16) was stage 0 (n=2, 12.5%), stage IA (n=3, 18.8%), stage IB (n=2, 12.5%), stage IIA (n=2, 12.5%), stage IIB (n=2, 12.5%), stage III (n=1, 6.3%), and stage IV (n=4, 25%). The UICC stage distribution in the nonsurveillance group (n=431) was stage 0 (n=4, 0.9%), stage IA (n=28, 6.5%), stage IB (n=27, 6.3%), stage IIA (n=86, 20.0%), stage IIB (n=48, 11.1%), stage III (n=56, 13.0%), and stage IV (n=182, 42.2%). The HCC surveillance group had significantly more patients with stage 0 disease than with stages IA through IV (P=.02). Similar results were observed when including stages IA (P=.007) and IB (P=.004) as early stages but not stage IIA (P=.10). A dilated pancreatic duct led to a PC diagnosis in all 6 patients with stage 0 disease. CONCLUSION: Patients with HBV- and HCV-related chronic liver disease had an early PC diagnosis during HCC surveillance. Careful evaluation of the pancreas is warranted during HCC surveillance.

Lenvatinib has anti-tumor activity against advanced hepatocellular carcinoma (HCC). Hypothyroidism is also a frequent complication in patients treated with lenvatinib. However, studies on lenvatinib-induced thyroid toxicity and destructive thyroiditis are limited. Therefore, this study aimed to clarify the frequency and timing of thyroid abnormalities in lenvatinib for unresectable HCC. This retrospective study enrolled 50 patients with advanced HCC treated with lenvatinib. Patients were classified to have euthyroid, subclinical hypothyroidism, overt hypothyroidism, and thyrotoxicosis. The timing of thyroid dysfunction was assessed, and risk factors for incident hypothyroidism or thyrotoxicosis were evaluated using multivariate models. Subclinical hypothyroidism, overt hypothyroidism, and thyrotoxicosis occurred in 7 (14.0%), 26 (52.0%), and 5 (10.0%) patients, respectively. In the 33 patients with hypothyroidism, 27 (84.4%) developed the condition within 2 weeks of starting lenvatinib treatment. Of the 5 patients with thyrotoxicosis, 3 developed the condition within 8 weeks of starting lenvatinib administration. One patient developed thyrotoxicosis in only 1 week of the initiation of treatment. No correlation between the presence of antibodies and the incidence and severity of thyroid dysfunction due to the autoimmune mechanism was observed. The progression-free survival was significantly better in the hypothyroidism group. Lenvatinib treatment for unresectable HCC not only causes hypothyroidism, but also thyrotoxicosis. Moreover, these thyroid conditions develop within the early period of treatment at a higher prevalence. Patients with thyroid dysfunction had better prognosis. Based on these results, in patients administered with lenvatinib, there is need for careful assessment for the possibility of thyroid dysfunction from the onset of treatment.

OBJECTIVES: Dipeptidyl peptidase-4 inhibitors (DPP-4Is) can be classified into three categories according to their binding subsites. We wished to clarify the efficacy of switching between DPP-4Is according to their binding subsites. MATERIALS AND METHODS: We undertook a retrospective study of the medical records of patients who switched from one DPP-4I to another. RESULTS: Among 62 patients eligible for study inclusion, the mean change in the glycated hemoglobin (HbA1c) level between different categories of DPP-4I was -0.35 (95% CI, -0.12 to -0.58; n = 59). The mean change in the HbA1c level between each class of DPP-4I was calculated. From class 3 to class 2 it was -0.45 (n = 25); from class 3 to class 1 it was -0.36 (n = 17); from class 1 to class 2 it was -0.24 (n = 7); from class 1 to class 3 it was 0.33 (n = 4); from class 2 to class 1 it was -0.30 (n = 5); from class 2 to class 3 it was -1.30 (n = 1). CONCLUSIONS: When switching DPP-4Is because of insufficient efficacy, consideration of their DPP-4 binding site may be beneficial.

Gastrointestinal motility is regulated by neural factors and humoral factors. Both motilin and ghrelin improve gastrointestinal motility, but many issues remain unclear. We prepared human motilin receptor transgenic (Tg) mice and performed experiments evaluating the effects of motilin, erythromycin (EM), and ghrelin. EM and ghrelin promoted gastric emptying (GE) when administered either peripherally or centrally to Tg mice. Atropine (a muscarinic receptor antagonist) counteracted GE induced by centrally administered EM, but not that induced by peripherally administered EM. The administration of EM in this model promoted the effect of mosapride (a selective serotonin 5-hydroxytryptamine 4 (5-HT4) receptor agonist), and improved loperamide (a μ-opioid receptor agonist)-induced gastroparesis. The level of acyl-ghrelin was significantly attenuated by EM administration. Thus, we have established an animal model appropriate for the evaluation of motilin receptor agonists. These data and the model are expected to facilitate the identification of novel compounds with clinical potential for relieving symptoms of dyspepsia and gastroparesis.

Obesity-induced adipose-tissue dysfunction is a critical contributor to the pathogenesis of nonalcoholic fatty liver disease (NAFLD). B cell-activating factor (BAFF) is an adipokine related to impaired insulin sensitivity, and the serum BAFF concentration is associated with NAFLD severity. In this study, we aimed to determine the direct in vivo role of BAFF in the development of insulin resistance, adipocyte dysfunction, and hepatic steatosis using BAFF-/- mice fed a high-fat diet (HFD). HFD-fed BAFF-/- mice exhibited significantly improved insulin sensitivity despite their increased weight gain and adiposity relative to HFD-fed wild-type mice. Moreover, inflammation, especially the accumulation of CD11c+ adipose-tissue macrophages, and fibrosis of epididymal adipose tissue were reduced, contributing to healthy adipose-tissue expansion in obese BAFF-/- mice. In line with metabolically healthy obesity, hepatic steatosis also decreased, and we observed attenuated de novo lipogenesis in both the livers and hepatocytes of BAFF-/- mice. Our data revealed that BAFF serves as a potential stimulator of unhealthy adipose-tissue expansion by triggering inflammation and fibrosis and ultimately leading to enhanced insulin resistance and NAFLD. Therefore, these results suggest that BAFF is a promising target for diabetes and NAFLD treatment.

In several studies of patients with type 2 diabetes mellitus, a positive association between depressive symptoms and erectile dysfunction (ED) has been reported. No evidence exists, however, regarding the association between depressive symptoms and ED among Japanese patients with type 2 diabetes mellitus. Thus, we examined this issue among Japanese patients with type 2 diabetes mellitus. Study subjects were 469 male Japanese patients with type 2 diabetes mellitus, aged 19 years or over. ED, moderate to severe ED and severe ED were defined as present when a subject had a Sexual Health inventory for Men score &lt;22, &lt; 12 and &lt; 8, respectively. Depressive symptoms were defined as present when a subject had a Self-Rating Depression Scale (SDS) score &gt;49. Adjustment was made for age, body mass index, waist, duration of type 2 diabetes, current smoking, current drinking, hypertension, dyslipidemia, coronary artery disease, stroke, glycated hemoglobin and diabetic neuropathy. The prevalence values of depressive symptoms, moderate to severe ED and severe ED were 15.1%, 64.2% and 51.0%, respectively. Depressive symptoms were independently positively associated with moderate to severe ED and severe ED (adjusted odds ratios were 2.23 (95% confidence interval (CI): 1.17-4.43) and 1.86 (95% CI: 1.04-3.41), respectively). In Japanese patients with type 2 diabetes mellitus, depressive symptoms may be associated with ED.

Only limited epidemiological evidence exists regarding the relationship between diabetic neuropathy and erectile dysfunction (ED) among Japanese patients with type 2 diabetes mellitus. To investigate the relationship between diabetic neuropathy and ED among Japanese patients with type 2 diabetes mellitus, a multicenter cross-sectional study was conducted in 287 male Japanese patients with type 2 diabetes Mellitus, age (19-65 years). Diabetic neuropathy was diagnosed if the patients showed two or more of the following three characteristics: neuropathic symptoms, decreased or disappeared Achilles tendon reflex and/or abnormal vibration perception. ED, moderate to severe ED, and severe ED were defined as present when a subject had a Sexual Health Inventory for Men score &lt; 22, &lt; 12 and &lt; 8, respectively. The prevalenee values of diabetic neuropathy and severe ED were 47.0 and 39.0%, respectively. Diabetic neuropathy was independently positively associated with severe ED, but not ED and moderate ED: the adjusted odds ratio was 1.90 (95% confidence interval: 1.08-3.38). No relationships were found between diabetic retinopathy or diabetic nephropathy and ED. Diabetic neuropathy is positively associated with severe erectile dysfunction among Japanese type 2 diabetes mellitus patients aged &lt; 65 years.

AIMS: Diabetes was significantly positively associated with urgency incontinence in several epidemiological studies. We examine the association between diabetic neuropathy, which we defined based on neuropathic symptoms, the absence of the Achilles reflex, and/or abnormal vibration perception, and urgency incontinence among Japanese patients with type 2 diabetes mellitus. METHODS: Study subjects were 742 Japanese patients with type 2 diabetes mellitus, aged 19-70 years, who had undergone blood tests at our institutions. A self-administered questionnaire was used to collect information on the variables under study. Urgency incontinence was defined as present when a subject answered "once a week or more" to the question: "Within one week, how often do you leak urine because you cannot defer the sudden desire to urinate ?". Diabetic neuropathy was diagnosed if the patients showed two or more of the following three characteristics: neuropathic symptoms, the absence of the Achilles reflex, and/or abnormal vibration perception. Adjustment was made for sex, age, body mass index, duration of type 2 diabetes mellitus, current smoking, hypertension, dyslipidemia, glycated hemoglobin, stroke, coronary artery disease, insulin therapy, diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy. RESULTS: The prevalence of urgency incontinence was 8.6%. Diabetic neuropathy was independently positively associated with urgency incontinence: the adjusted OR was 2.20 (95%CI: 1.16-4.36). Associations between diabetic retinopathy or nephropathy and the prevalence of urgency incontinence were not significant. CONCLUSIONS: In Japanese patients with type 2 diabetes mellitus, only diabetic neuropathy was independently positively associated with urgency incontinence. Neurourol.

Multipuncture radiofrequency ablation is expected to produce a large ablated area and reduce intrahepatic recurrence of hepatocellular carcinoma; however, it requires considerable skill. This study evaluated the utility of a new simulator system for multipuncture radiofrequency ablation. To understand positioning of multipuncture electrodes on three-dimensional images, we developed a new technology by expanding real-time virtual ultrasonography. We performed 21 experimental punctures in phantoms. Electrode insertion directions and positions were confirmed on computed tomography, and accuracy and utility of the simulator system were evaluated by measuring angles and intersections for each electrode. Moreover, to appropriately assess placement of the three electrodes, puncture procedures with or without the simulator were performed by experts and non-experts. Technical success was defined as maximum angle and distance ratio, as calculated by maximum and minimum distances between electrodes. In punctures using 2 electrodes, correlations between angles on each imaging modality were strong (ultrasound vs. simulator: r = 0.991, p<0.001, simulator vs. computed tomography: r = 0.991, p<0.001, ultrasound vs. computed tomography: r = 0.999, p<0.001). Correlations between distances in each imaging modality were also strong (ultrasound vs. simulator: r = 0.993, p<0.001; simulator vs. computed tomography: r = 0.994, p<0.001; ultrasound vs. computed tomography: r = 0.994, p<0.001). In cases with 3 electrodes, distances between each electrode correlated strongly (yellow-labeled vs. red-labeled: r = 0.980, p<0.001; red-labeled vs. blue-labeled: r = 0.953, p<0.001; yellow-labeled vs. blue-labeled: r = 0.953, p<0.001). Both angle and distance ratio (expert with simulator vs. without simulator; p = 0.03, p = 0.02) were significantly smaller in procedures performed by experts using the simulator system. The new simulator system appears to accurately guide electrode positioning. This simulator system could allow multipuncture radiofrequency ablation to be performed more effectively and comfortably.

BACKGROUND: Accurately evaluating liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) is important for identifying those who may develop complications. The aims of this study were (1) to measure serum Wisteria floribunda agglutinin-positive Mac-2 binding protein (WFA(+)-M2BP) using the glycan sugar chain-based immunoassay and (2) to compare the results with clinical assessments of fibrosis. METHODS: Serum WFA(+)-M2BP values were retrospectively evaluated in 289 patients with NAFLD who had undergone liver biopsy. Histological findings were evaluated by three blinded, experienced liver-specific pathologists. RESULTS: For stages 0 (n = 35), 1 (n = 113), 2 (n = 49), 3 (n = 41), and 4 (n = 51) of liver fibrosis, the serum WFA(+)-M2BP cutoff indexes were 0.57, 0.70, 1.02, 1.57, and 2.96, respectively. Multivariate regression analysis showed that serum WFA(+)-M2BP values were associated with the stage of fibrosis (≥stage 2). The areas under the receiver operating characteristic curve (AUROC), sensitivity, and specificity of serum WFA(+)-M2BP were 0.876, 85.9, and 74.6%, respectively, for severe fibrosis (≥stage 3) and were 0.879, 74.6, and 87.0%, respectively, for cirrhosis. When compared with six non-invasive conventional markers, serum WFA(+)-M2BP had the greatest AUROC for diagnosing severe fibrosis and cirrhosis. CONCLUSIONS: Serum WFA(+)-M2BP values are useful for assessing the stage of liver fibrosis in patients with NAFLD.

BACKGROUND: Epidemiologic studies show an association between short sleep duration and the presence of nonalcoholic fatty liver disease (NAFLD). This study examined the association between short sleep duration and the onset of NAFLD. METHODS: This community-based, retrospective, longitudinal cohort study included 6,370 Japanese subjects who had undergone annual health check-ups more than twice at a single center between April 2003 and March 2010. After excluding 3,941 subjects, the records of 2,429 Japanese subjects were reviewed. RESULTS: Two groups comprised the study cohort: those with short (≤ 6 h) sleep durations (n = 1,543) and those with moderate (7-8 h) sleep durations (n = 886). During the observation period, 296 subjects developed NAFLD. Multivariate analysis identified an association between short sleep duration and the reduced onset of NAFLD in men (odds ratio: 0.551, 95% confidence interval 0.365-0.832, p = 0.005). There was no association between short sleep duration and NAFLD onset in women. The prevalence of NAFLD onset in men increased significantly as sleep duration increased, as follows: 12.5, 18.4, and 27.4% among subjects who had sleep durations of ≤ 4, 5-6, and 7-8 h, respectively (p = 0.02). CONCLUSIONS: This study demonstrates an association between sleep duration and NAFLD onset. Short sleep duration reduced the risk of NAFLD onset in men. Correct recognition is important to prevent disease progression and further complications.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a risk factor for diabetes and cardiovascular disease that could progress to nonalcoholic steatohepatitis, cirrhosis, and liver failure. We aimed to assess the relationship between NAFLD and lifestyle habits. METHODS: Using a community-based, cross-sectional design, the records of 11,094 Japanese subjects who had undergone at least 1 annual health checkup were reviewed. RESULTS: Of the 6,370 subjects who qualified for enrolment, 1,346 met the diagnostic criteria for NAFLD. The prevalence rate (PR) of NAFLD increased significantly to 36.6, 41.5, and 41.1 % with no snacking, snacking less than once/day, and snacking ≥2 times/day, respectively, in men (P = 0.0495) and to 10.8, 11.7, and 15.3 %, respectively, in women (P = 0.002). In men, the NAFLD PR decreased significantly to 48.8, 36.9, and 29.9 % with no exercise, exercise consciousness, and periodical exercise, respectively (P < 0.001). In women, the NAFLD PR decreased significantly to 19.3, 13.5, 11, and 8 % with sleep durations of ≤4, 5-6, 7-8, and ≥9 h, respectively (P = 0.003). Periodical exercise was identified as an independent factor associated with NAFLD in men (odds ratio 0.707, 95 % confidence interval 0.546-0.914; P = 0.008). CONCLUSIONS: Performing regular exercise was associated with a reduced risk for NAFLD in men. Men with a high risk for NAFLD can be identified using questionnaires on exercise in an outpatient setting. Disease progression and further complications may be prevented by educating high-risk NAFLD patients about the importance of exercise.

PURPOSE: To prospectively evaluate whether the characteristics of hepatic blood flow change during the early stages of fibrosis in patients with nonalcoholic fatty liver disease (NAFLD). MATERIALS AND METHODS: All participants provided written informed consent, and the study protocols were approved by the institutional ethics committee. A total of 121 patients with NAFLD that was diagnosed at histologic examination were enrolled. Hepatic blood flow was measured by means of Doppler ultrasonography (US), and the ratio of arterial to portal blood flow (arterioportal ratio) was calculated. Elasticity of the spleen was measured by means of real-time tissue elastography. The elastic ratio was measured as the value in the small splenic vessel divided by the value of the splenic parenchyma. The arterioportal ratio and splenic elasticity were compared in patients with all stages of fibrosis (F0-F4) and with all levels of platelet counts. Correlations among the resistive index of the hepatic artery and that of the splenic artery, the fibrosis 4 index, hepatic elasticity, arterioportal ratio, splenic elasticity, and platelet counts were analyzed. Univariate and multivariate logistic regression analyses were performed. Correlations in patients with platelet counts greater than 200 000/μL also were analyzed. RESULTS: The mean ± standard deviation arterioportal ratio was significantly higher at fibrosis stage 2 (2.4 ± 0.6) than at fibrosis stage 0 (1.8 ± 0.4) in patients with NAFLD (P < .01). Increased splenic stiffness at earlier stages of fibrosis also was observed in patients with NAFLD (fibrosis stage 2, 4.4 ± 2.3; fibrosis stage 0, 3.2 ± 1.9; P < .05). In patients with NAFLD with platelet counts higher than 200 000/μL, pericellular fibrosis was the only significant predictor of hepatic hemodynamic change at multivariate analysis (odds ratio, 7.17; 95% confidence interval: 1.33, 57.13; P = .021). CONCLUSION: Change in hepatic blood flow occurred during the earliest stage of hepatic fibrosis in patients with NAFLD because of outflow block in the sinusoidal area.

Subclinical hypothyroidism (SCH) has been associated with type 2 diabetes mellitus. However, it is unknown whether common complications of type 2 diabetes, such as diabetic nephropathy, are also present with SCH. Here, we investigated the association between SCH and diabetic nephropathy among Japanese patients with type 2 diabetes mellitus. In this multicenter cross-sectional study, we recruited 414 such patients who had no previous history of thyroid disease. Serum thyroid hormone levels and the urinary albumin:creatinine ratio were measured. SCH was defined as an elevated thyroid-stimulating hormone (TSH) level (>4.0 mIU/L), and diabetic nephropathy was defined as urinary albumin/creatinine ratio ≥300 mg/g. The prevalence of SCH was 8.7% (n = 36) among patients with type 2 diabetes mellitus. The SCH group had a higher prevalence of dyslipidemia (p = 0.008) and diabetic nephropathy (p = 0.014) than the euthyroid group. Multivariate analysis identified significant positive associations between diabetic nephropathy and SCH (odds ratio [OR], 3.51; 95% confidence interval [CI], 1.10-10.0; p = 0.034), hypertension (OR, 4.56; 95% CI, 1.69-14.7; p = 0.001), and smoking (OR, 3.02; 95% CI, 1.14-7.91; p = 0.026). SCH may be independently associated with diabetic nephropathy in Japanese patients with type 2 diabetes mellitus.

BACKGROUND: It is not clear whether elevated uric acid is a risk factor for the onset of impaired fasting glucose after stratifying by baseline fasting plasma glucose levels. We conducted a community-based retrospective longitudinal cohort study to clarify the relationship between uric acid levels and the onset of impaired fasting glucose, according to baseline fasting plasma glucose levels. METHODS: We enrolled 6,403 persons (3,194 men and 3,209 women), each of whom was 18-80 years old and had > 2 annual check-ups during 2003-2010. After excluding persons who had fasting plasma glucose levels ≥ 6.11 mM and/or were currently taking anti-diabetic agents, the remaining 5,924 subjects were classified into quartiles according to baseline fasting plasma glucose levels. The onset of impaired fasting glucose was defined as fasting plasma glucose ≥ 6.11 mM during the observation period. RESULTS: In the quartile groups, 0.9%, 2.1%, 3.4%, and 20.2% of the men developed impaired fasting glucose, respectively, and 0.1%, 0.3%, 0.5%, and 5.6% of the women developed impaired fasting glucose, respectively (P trend <0.001). After adjusting for age, body mass index, systolic blood pressure, triacylglycerols, high density lipoprotein-cholesterol, creatinine, fatty liver, family history of diabetes, alcohol consumption, and current smoking, uric acid levels were positively associated with onset of impaired fasting glucose in men with highest-quartile fasting plasma glucose levels (adjusted hazard ratio, 1.003; 95% confidence interval, 1.0001-1.005, P = 0.041). CONCLUSIONS: Among men with high fasting plasma glucose, hyperuricemia may be independently associated with an elevated risk of developing impaired fasting glucose.

In Japan, the prevalence of obesity in adult men has increased since the 1970s, while that in adult women has not changed. The prevalence of obesity in 5-, 8-, 11-, and 14-year-old boys and girls increased from the late 1980s to late 1990 s and has decreased since 2000, while that in 17-year-old girls increased in 2002, similar to that for boys, but has since decreased. In 2009, 33.3% of adult men and 25.0% of adult women were obese, and 8-10% of children (age, 5-17 years) were obese. The prevalence of visceral obesity in adults was 50.8% of men and 18.0% of women. Obesity, especially visceral obesity, affects insulin resistance and increases metabolic diseases (diabetes mellitus, dyslipidemia, hypertension, cardiovascular disease, and non-alcoholic fatty liver disease [NAFLD]) and various cancers. In Japan, with a body mass index (BMI) of 23-25 as the reference category, the hazard ratio of total mortality is 1.36 for a BMI of 30-40 in men and 1.37 with a BMI of 30-40 in women. The frequency of patients with NAFLD has gradually increased in proportion to the increase in the population with obesity. From recent studies in Japan, the number of NAFLD patients is estimated to be 10 million, and around 2 million are considered to have non-alcoholic steatohepatitis. Dietary and behavioral modification is effective for body weight loss and for improvement of obesity-related gastrointestinal liver diseases. If necessary, bariatric surgery is useful for obesity treatment.

Non-alcoholic fatty liver disease (NAFLD) may progress to cirrhosis, liver failure, and complicated hepatocellular carcinoma. In addition, NAFLD is a risk factor for the development of other serious diseases, such as diabetes or cardiovascular disease. Therefore, the detection of early-stage NAFLD is important. Many studies have described the factors that predict the presence of NAFLD and its onset, and several markers have been identified. These markers have enabled the identification of high-risk patients and have improved routine medical practice. To prevent advanced disease, clinicians need to have simple markers that predict the onset of NAFLD so that interventions can be started at much earlier stages of disease. This review summarizes the current state of knowledge regarding independent factors, as reported in large studies, that predict the presence of NAFLD and its onset, especially markers that can be used in daily medical practice, such as physical measurements and blood tests.

BACKGROUND: Although the outcomes of pancreatic cancer have been improved by gemcitabine, the changes in its characteristics and long-term outcomes within the gemcitabine era remain unclear. This study was conducted to identify clinical characteristics of pancreatic cancer patients within the gemcitabine era. METHODS: A retrospective chart review was performed at 10 centers for 1,248 consecutive patients who were ever considered to have a diagnosis of pancreatic cancer between 2001 and 2010. Data collected included demographics, diagnosis date, clinical stage, treatment, and outcome 1,082 patients met the inclusion criteria and were analyzed further. The chi-square test, Student's t-test, and Mann-Whitney U-test were used for statistical analysis. Outcomes were analyzed using the Kaplan-Meier method and Cox proportional hazards regression. Differences in survival analyses were determined using the log-rank test. RESULTS: The distribution of clinical stages was: I, 2.2% II, 3.4% III, 13% IVa, 27% and IVb, 55%. Chemotherapy alone was administered to 42% of patients and 17% underwent resection. The 1-, 3-, and 5-year survival rates were 39%, 13%, and 6.9%, respectively. The median survival time was 257 days, but differed considerably among treatments and clinical stages. Demographics, distribution of clinical stage, and cause of death did not differ between groups A (2001-2005, n=406) and B (2006-2010, n=676). However, group B included more patients who underwent chemotherapy (P<0.0001) and fewer treated with best supportive care (P=0.0004), mirroring improvements in this group's long-term outcomes (P=0.0063). Finally, factors associated with long-term outcomes derived from multivariate analysis were clinical stage (P<0.0001), location of the tumor (P=0.0294) and treatments (surgery, chemotherapy) (<0.0001). CONCLUSIONS: Long-term outcomes in pancreatic cancer has improved even within the gemcitabine era, suggesting the importance of offering chemotherapy to patients previously only considered for best supportive care. Most patients are still diagnosed at an advanced stage, making clinical strategy development for diagnosing pancreatic cancer at earlier stages essential.

OBJECTIVE: We estimated the prevalence of nocturnal intermittent hypoxia, a surrogate marker of obstructive sleep apnoea, among type 2 diabetes mellitus (T2DM) patients and examined the association between nocturnal intermittent hypoxia and microvascular diseases. DESIGN AND METHODS: We recruited 513 Japanese patients (292 men and 221 women) with T2DM. Nocturnal intermittent hypoxia was diagnosed using the 3% oxygen desaturation index, with less than five events per hour corresponding to normal and five events or more per hour corresponding to nocturnal intermittent hypoxia. RESULTS: The prevalence of nocturnal intermittent hypoxia was 45.4% among T2DM patients. The nocturnal intermittent hypoxia group was older and had a higher BMI, greater weight change since the age of 20 years, higher smoking rate and increased prevalence of hypertension, hyperlipidaemia, microalbuminuria and macroalbuminuria. Microalbuminuria (model 1: odds ratio (OR), 3.41; 95% CI, 1.85-6.40; model 2: OR, 3.69; 95% CI, 1.85-7.59 and model 3: OR, 3.12; 95% CI, 1.45-6.95) and nephropathy (model 1: OR, 4.51; 95% CI, 1.58-15.1; model 2: OR, 7.31; 95% CI, 2.11-31.6 and model 3: OR, 5.23; 95% CI, 1.45-23.8) were derived as factors from all the three statistical models and constantly associated with nocturnal intermittent hypoxia only in women. CONCLUSIONS: Nocturnal intermittent hypoxia was highly prevalent among T2DM patients and may be an independent associated risk factor for microalbuminuria in Japanese women with T2DM.

PURPOSE: B cell-activating factor (BAFF) is expressed in adipocytes and affects lipogenesis and insulin sensitivity. In addition, the BAFF receptor is expressed in visceral adipose tissue and liver. The aim of this study was to analyze serum BAFF levels in patients with nonalcoholic steatohepatitis (NASH) and simple steatosis (SS) and to compare their respective clinical and histological findings. METHODS: A total of 96 patients with nonalcoholic fatty liver disease (20 with SS and 76 with NASH) were enrolled and their serum BAFF levels were analyzed. Comprehensive blood chemistry analysis and histological examination of liver samples were also conducted. RESULTS: Serum BAFF levels were higher in patients with NASH than in those with SS (p = 0.016). NASH patients with ballooning hepatocytes and advanced fibrosis had higher levels of BAFF in sera (p = 0.016 and p = 0.006, respectively). In addition, the prevalence of NASH increased significantly as the serum BAFF level increased (p = 0.004). Higher serum BAFF levels were found to be an independent risk factor for development of NASH (OR 1.003, 95% CI 1.0003-1.006; p = 0.047). CONCLUSIONS: Nonalcoholic steatohepatitis patients had higher levels of serum BAFF than patients with SS, and higher levels were associated with the presence of hepatocyte ballooning and advanced fibrosis. The serum BAFF level may be a useful tool for distinguishing NASH from SS.

Chronic inflammation is an important contributor to the development and progression of metabolic syndrome. Recent evidence indicates that, in addition to innate immune cells, adaptive immune cells have an important role in this process. We previously showed that the serum level of B-cell-activating factor (BAFF) was increased in patients with nonalcoholic steatohepatitis. However, it is currently unknown whether BAFF and BAFF-R (BAFF-R) have a role in lipid metabolism in the liver. To address this issue, the role played by BAFF and BAFF-R signaling in the development of insulin resistance and hepatic steatosis was examined in BAFF-R(-/-) mice fed a high-fat diet (HFD). Furthermore, the effect of BAFF on lipid metabolism in hepatocytes was analyzed in vitro. BAFF-R(-/-) mice showed improvements in HFD-induced obesity and insulin resistance. In addition, the number of B cells, levels of serum IgG, and inflammation of visceral fat were reduced in these mice. However, the expression of steatogenic genes and fatty acid deposition in the liver was higher in these mice than in control mice. BAFF was also found to downregulate the expression of steatogenesis genes and enhance steatosis in hepatocytes through BAFF-R. Collectively, these data indicated that, in addition to its known functions in inflammation and glucose metabolism, BAFF has a protective role in hepatic steatosis by regulating lipid metabolism in the liver.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) can progress to advanced liver disease and non-liver-related diseases. To prevent NAFLD onset, clinicians must be able to easily identify high-risk NAFLD patients so that intervention can begin at an earlier stage. We sought to identify the predictive factors for NAFLD onset. METHODS: In a community-based, longitudinal design, the records of 6,403 Japanese subjects were reviewed to identify those meeting the criteria for NAFLD onset. Univariate and multivariate logistic regression analyses were used to identify predictive factors for NAFLD onset. The accuracy of different models was evaluated according to their areas under the receiver operating characteristic curves. Comparative risk analysis was performed using the Kaplan-Meier method. RESULTS: Multivariate analysis of 400 subjects who met the criteria for the onset of NAFLD during the observation period confirmed that body mass index (BMI) at baseline was the most useful predictive factor for NAFLD onset in both sexes. Cutoff levels of BMI for NAFLD onset were estimated at 23 kg/m2 for men and 22.2 kg/m2 for women. The cumulative onset rate of NAFLD was significantly higher in the high BMI group than in the low BMI group in both sexes (P < 0.001). CONCLUSION: BMI was confirmed as the most useful predictive factor for NAFLD onset in both sexes; its cutoff levels were similar to those recommended by the World Health Organization for helping to prevent metabolic disease. An accurate BMI cutoff level will enable clinicians to identify subjects at risk for NAFLD onset.

Adipose tissue functions as a key endocrine organ by releasing multiple bioactive substances, and plays a key role in the integration of systemic metabolism. We have previously shown that B cell activating factor is produced mainly in visceral adipose tissue and affects insulin sensitivity in obese individuals. In this study, we identified the signals that lead to production of B cell activating factor in adipocytes. 3T3-L1 and C3H/10T 1/2-clone 8 cells showed increased B cell activating factor expression upon exposure to hydrogen peroxide, and these changes were inhibited by treatment with the antioxidant N-acetyl-cysteine. B cell activating factor levels in both serum and visceral adipose tissue were increased in high fat diet-fed mice, and these increases were correlated with oxidative stress. In addition, serum BAFF levels in high fat diet-fed mice were reduced by N-acetyl-cysteine treatment. We also found that oxidative stress-induced B cell activating factor expression in adipocytes was regulated by NF-κB activation. These data indicate that control of the redox state in visceral adipose tissue is a potentially useful target for treating metabolic syndromes through regulation of adipokine production.

The motilin receptor belongs to a family of Class I G protein-coupled receptors, and is an important endogenous regulator of gastrointestinal motor function. Motilin and erythromycin, two chemically distinct full agonists of the motilin receptor, are known to bind to distinct regions of this receptor, based on previous systematic mutagenesis of extracellular regions that dissociated the effects on these two agents. The action of these different chemical classes of agonists likely yields a common activation state of the cytosolic face of this receptor that is responsible for interaction with its G protein. In the current work, we studied the predicted transmembrane (TM) domains of this receptor for functional responses to motilin and erythromycin. Motilin receptor constructs were prepared in which each residue in the TM domains was mutated to alanine or valine. Each construct was expressed in COS cells and characterized for motilin and erythromycin binding and intracellular calcium responses stimulated by both agonists. Constructs with mutations of residues, Asp94, Leu95, Arg97 and Trp99 in TM2, Ser169 in TM4, and Tyr321 and Glu325 in TM6, were responsible for the negative impact on biological activity stimulated by erythromycin, but had no effect on motilin responses. On the other hand, constructs with mutations of residues, Leu113 in TM3, Pro172 in TM4, Trp250 and Tyr255 in TM5, and Gln334 in TM7, were negatively responsive to both erythromycin and motilin. These data support important roles of new regions in the TM domains of the motilin receptor for erythromycin action, suggesting differential mechanisms of actions by peptidyl and non-peptidyl ligands.

We previously reported that serum interleukin-18 (IL-18) levels were significantly increased in hyperthyroid Graves' disease patients. The development of insulin resistance in hyperthyroidism has been documented. We investigated the relationship between IL-18 and insulin resistance in patients with hyperthyroid Graves' disease and in experimental hyperthyroid mice. Then, we examined whether IL-18 induces insulin resistance in mice injected with IL-18 for a week. A significant positive correlation was observed between serum IL-18 levels and parameters such as thyroid functions and homeostasis model assessment for insulin resistance in hyperthyroid Graves' disease. In experimental hyperthyroid mice, IL-18 was significantly elevated. Insulin resistance increased in experimental hyperthyroid mice and IL-18-injected mice. These findings suggest IL-18 to be an important factor inducing insulin resistance in hyperthyroidism.

Hepatitis C virus (HCV) infection alters fatty acid synthesis and metabolism in association with HCV replication. The present study examined the effect of serum fatty acid composition on interferon (IFN)-based therapy. Fifty-five patients with HCV were enrolled and received IFN-based therapy. Patient characteristics, laboratory data (including fatty acids), and viral factors that could be associated with the anti-HCV effects of IFN-based therapy were evaluated. The effects of individual fatty acids on viral replication and IFN-based therapy were also examined in an in-vitro system. Multivariate logistic regression analysis showed that the level of serum palmitic acid before treatment and HCV genotype were significant predictors for rapid virological response (RVR), early virological response (EVR), and sustained virological response (SVR). High levels of palmitic acid inhibited the anti-HCV effects of IFN-based therapy. HCV replication assays confirmed the inhibitory effects of palmitic acid on anti-HCV therapy. The concentration of serum palmitic acid is an independent predictive factor for RVR, EVR, and SVR in IFN-based antiviral therapy. These results suggest that the effect of IFN-based antiviral therapy in patients with HCV infection might be enhanced by treatment that modulates palmitic acid levels.

UNLABELLED: The aim of this study was to prospectively measure liver stiffness with real-time tissue elastography in patients with nonalcoholic fatty liver diseases (NAFLD) and to compare the result with the clinical assessment of fibrosis using histological stage. One hundred and eighty-one prospectively enrolled patients underwent real-time tissue elastography, with the first 106 being analyzed as the training set and the remaining 75 being evaluated as the validation set. Hepatic and splenic elastic ratios were calculated and compared with stage of histological fibrosis. Portal hypertension (PH) was assessed. Real-time tissue elastography cut-off values by stage in the training set were 2.47 for F1, 2.67 for F2, 3.02 for F3, and 3.36 for F4. Using these cut-off values, the diagnostic accuracy of hepatic fibrosis in the validation set was 82.6%-96.0% in all stages. Only portal fibrosis correlated with the hepatic elastic ratio by multivariate analysis. The area under the receiver operating characteristic curve of elastic ratio better correlated than serum fibrosis markers in both early and advanced fibrosis stages. Patients with PH, defined by splenic elasticity, had early fibrosis. Patients with severe PH were found only in the group with cirrhosis. CONCLUSION: Real-time tissue elastography is useful in evaluating hepatic fibrosis and PH in patients with NAFLD.

The motilin receptor (MR) belongs to a family of Class I G protein-coupled receptors that also includes growth hormone secretagogue receptor (GHSR). Their potentially unique structure and the molecular basis of their binding and activation are not yet clear. We previously reported that the perimembranous residues in the predicted extracellular loops and amino-terminal tail of the MR were important for responses to the natural peptide ligand, motilin, and the transmembrane domains of the MR were important for a non-peptidyl ligand, erythromycin. We also reported that the perimembranous residues in the second extracellular loop of the GHSR were critical for natural ligand ghrelin binding and activity. The MR is 52% identical to GHSR, with 86% sequence identity in the transmembrane domains. In the current work, to gain insight into a relationship between MR and GHSR, we studied functional responses to motilin, erythromycin and ghrelin of expression cells of chimeric constructs of MR and GHSR and co-expression cells of both MR and GHSR. We also generated human MR transgenic mice, and clarified a relationship between motilin and ghrelin. MR(1-62)/GHSR(68-366) construct responded only to ghrelin, MR(1-102)/GHSR(108-366) responded to ghrelin and erythromycin, and MR(1-129)/GHSR(135-366) and MR(1-178)/GHSR(184-366) responded to erythromycin, while GHSR(1-183)/MR(179-412) responded to neither motilin, erythromycin nor ghrelin. MR and GHSR co-expression cells have no additional responses to these ligands. Motilin or erythromycin administration to human MR transgenic mice resulted in a decrease of serum acyl-ghrelin levels, while MR and GHSR mRNA expression in the gastrointestinal tracts were not changed. These data suggested that in species expressing both motilin-MR and ghrelin-GHSR, there is a compensatory relationship in vivo.

BACKGROUND: Untreated nonalcoholic fatty liver disease (NAFLD) may progress to liver cirrhosis or failure and is associated with the development of hepatocellular carcinoma, diabetes, and cardiovascular disease. It is therefore essential to diagnose and treat NAFLD at an early stage. To assist in this effort, this retrospective study explored the risk factors for NAFLD, and derived new surrogates, a revised alanine aminotransferase (ALT) cutoff level and a novel NAFLD index, to identify previously undiagnosed cases of NAFLD. METHODS: Using a community-based, cross-sectional design, the records of 6,370 Japanese subjects who had undergone at least 1 annual health check-up were reviewed for the identification of subjects meeting the diagnostic criteria for NAFLD and the variables associated with NAFLD for the estimation of ideal ALT cutoff levels. RESULTS: The results of multivariate analysis of the 1,346 subjects who met the diagnostic criteria for NAFLD confirmed that metabolic disease markers and a novel NAFLD index, using the variables derived from multivariate analysis, were also markers of NAFLD. The ALT cutoff levels for NAFLD diagnosis were estimated at 25 U/L for males and 17 U/L for females. CONCLUSIONS: ALT level and the novel NAFLD index were confirmed to be surrogate markers for NAFLD in addition to metabolic disease markers. The ALT cutoff level used in NAFLD diagnosis should be revised downward to identify subjects at risk of NAFLD to prevent NAFLD progression and the development of associated diseases.

Dipeptidyl peptidase-4 (DPP-4) inhibitors are a newer class of oral hypoglycemic agents for the management of diabetes that elevate the plasma concentration of active glucagon-like peptide-1 via inhibition of DPP-4. They effectively lower not only glycosylated hemoglobin levels, but also fasting and postprandial plasma glucose levels. Patients with diabetes occasionally consume an overdose of oral hypoglycemic agents in suicide attempts: the prevalence of depression is high in patients with diabetes, and depression is a strong risk factor for suicide. We encountered an 86-year-old woman with type 2 diabetes and depression, who was transferred to the emergency room 4h after ingestion of 1,700 mg of the DPP-4 inhibitor sitagliptin (1,700 mg is 17 times greater than the approved maximum dose). Upon arrival, she was fully conscious, plasma glucose was 124 mg/dL, and serum immunoreactive insulin level was 5.81 µU/mL. Thereafter, the plasma concentration of sitagliptin rose to 3,793 nM, which is 4.5 times higher than the value found under regular treatment with the maximum dose. The patient did not suffer from hypoglycemia, suggesting that a single oral overdose of sitagliptin is unlikely to cause hypoglycemia. A literature review of oral anti-diabetic agents revealed that overdose of biguanides is occasionally fatal when immediate intensive care is not provided. In summary, sitagliptin is a good treatment option for diabetic elderly patients or patients with psychiatric disorders who are suicidal and do not require insulin.

Branched-chain amino acid (BCAA) supplements have mainly been administered as a nutritional intervention for decompensated liver cirrhosis. Several studies have shown that short-term BCAA supplementation improves insulin and glucose tolerance in patients with liver cirrhosis. However, the long-term effects of BCAA supplementation on glucose tolerance and in patients with nonalcoholic steatohepatitis (NASH)-related liver cirrhosis are unknown. Herein, we report 2 cases of NASH-related liver cirrhosis in which long-term BCAA supplementation improved glycemic control. We conclude that in the absence of an effective conventional therapy for NASH-related liver cirrhosis, BCAA supplementation should be considered as an alternative treatment.

Visceral adipose tissue (VAT) inflammation has been linked to the pathogenesis of insulin resistance and metabolic syndrome. VAT has recently been established as a new component of the immune system and is involved in the production of various adipokines and cytokines. These molecules contribute to inducing and accelerating systemic insulin resistance. In this report, we investigated the role of B cell-activating factor (BAFF) in the induction of insulin resistance. We investigated BAFF levels in the sera and VAT of obese mice. In obese mice, the BAFF levels were preferentially increased in VAT and sera compared to these levels in normal control mice. Next, we treated mice with BAFF to analyze its influence on insulin sensitivity. BAFF impaired insulin sensitivity in normal mice. Finally, we investigated the mechanisms underlying insulin resistance induced by BAFF in adipocytes. BAFF also induced alterations in the expression levels of genes related to insulin resistance in adipocytes. In addition, BAFF directly affected the glucose uptake and phosphorylation of insulin receptor substrate-1 in adipocytes. We propose that autocrine or paracrine BAFF and BAFF-receptor (BAFF-R) interaction in VAT leads to impaired insulin sensitivity via inhibition of insulin signaling pathways and alterations in adipokine production.

The Class A family of guanine nucleotide-binding protein (G protein)-coupled receptors that includes receptors for motilin, ghrelin, and growth hormone secretagogue (GHS) has substantial potential importance as drug targets. Understanding of the molecular basis of hormone binding and receptor activation should provide insights helpful in the development of such drugs. We previously reported that Cys residues and the perimembranous residues in the extracellular loops and amino-terminal tail of the motilin receptor are critical for peptide ligand, motilin, binding and biological activity. In the current work, we focused on the predicted extracellular domains of the human GHS receptor 1a, and identified functionally important residues by using sequential deletions ranging from one to twelve amino acid residues and site-directed replacement mutagenesis approach. Each construct was transiently expressed in COS cells, and characterized for ghrelin- and growth hormone releasing peptide (GHRP)-6-stimulated intracellular calcium responses and ghrelin radioligand binding. Cys residues in positions 116 and 198 in the first and second extracellular loops and the perimembranous Glu¹⁸⁷ residue in the second extracellular loop were critical for ghrelin and GHRP-6 biological activity. These results suggest that Cys residues in the extracellular domains in this family of Class A G protein-coupled receptor is likely involved in the highly conserved and functionally important disulfide bond, and that the perimembranous residues contribute peptide ligand binding and signaling.

BACKGROUND/AIMS: The magnitude of antigen-specific immunity was assessed in a murine model of nonalcoholic fatty liver diseases (NAFLD). Because antigen-specific immunity was diminished in NAFLD mice, the underlying mechanisms were evaluated through analysis of the functions of antigen-presenting dendritic cells (DC) and other immunocytes. METHODS: For 12 weeks, NAFLD mice received a high-fat (60%) and high-calorie (520 kcal/100 g) diet. C57BL/6 mice (controls) received a standard diet. NAFLD mice and control mice were immunized with hepatitis B vaccine containing hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg). Antibody to HBsAg (anti-HBs), HBsAg and HBcAg-specific cellular immune response and functions of whole spleen cells, T lymphocytes, B lymphocytes and spleen DCs of NAFLD and control mice were assessed in vitro. RESULTS: Levels of anti-HBs and the magnitude of proliferation of HBsAg and HBcAg-specific lymphocytes were significantly lower in NAFLD mice than control mice (P < 0.05). The spleen cells of NAFLD mice produced significantly higher levels of inflammatory cytokines (P < 0.05) and exhibited significantly increased T cell proliferation compared with control mice (P < 0.05). However, the antigen processing and presenting capacities of spleen DCs were significantly decreased in NAFLD mice compared with control mice (P < 0.05). Palmitic acid, a saturated fatty acid, caused diminished antigen processing and presenting capacity of both murine and human DCs. CONCLUSIONS: Nonalcoholic fatty liver disease mice exhibit decreased magnitudes of antigen-specific humoral and cellular immune responses. This effect is mainly, if not solely, due to impaired antigen processing and presentation capacities of DC.

BACKGROUND: Abundant amounts of natural killer (NK) cells are present in the liver, most of which are endowed with direct cytotoxic and inflammatory cytokine production capacities. However, the control of compromised immunity in the liver may be accomplished by a population of regulatory NK cells possessing suppressive or tolerogenic functions. AIMS: To identify and characterize regulatory NK cells in murine liver. METHODS: NK cells were isolated from the liver of C57BL/6 mice by magnetic-activated cells sorting (MACS). NK cells were stimulated with different agents and those cells that produced interleukin (IL)-10 were detected by flow cytometry and isolated by MACS. IL-10-producing NK cells were regarded as regulatory NK cells and the functional capacities of liver-derived regulatory NK cells were assessed in vitro. RESULTS: The frequencies of regulatory NK cells in the liver were 4.1 +/- 0.3% of hepatic NK cells and 0.45 +/- 0.02% of liver nonparenchymal cells. Regulatory NK cells produced abundant amounts of IL-10 in culture. These cells also suppressed the proliferative capacities of T cells and B cells in vitro. However, another population of NK cells that did not produce IL-10 (immunogenic NK cells) could not suppress lymphocyte proliferation. CONCLUSIONS: The presence of regulatory NK cells in the liver and their immunosuppressive capacities endowed these cells with the critical function of maintaining homeostasis under normal conditions. Exaggerated or impaired functions of these cells may also contribute to different pathological processes.

We describe laparoscopic findings of tuberculous peritonitis in a 68-year-old man and those at follow-up 8 months later. The initial laparoscopic findings revealed typical yellowish-white nodules on the liver surface, and histological findings showed granulomas with caseous necrosis. Laparoscopy 8 months later showed that anti-tubercular drugs had diminished the nodules and adhesions with a fibrin net appearance were evident. Laparoscopy and biopsy are useful for a rapid diagnosis of tuberculous peritonitis.

Fibrosing cholestatic hepatitis (FCH) is a serious disease in patients with recurrent hepatitis C after liver transplantation (LTx). Antiviral therapy is indicated in these patients; however, it is not always effective, and the prognosis of FCH is generally poor. Double filtration plasmapheresis (DFPP) has been shown to be effective at eliminating hepatitis C virus (HCV) in patients with chronic hepatitis C. We report a case of FCH with severe cholestasis (total bilirubin 34.2 mg/dl) after LTx. Combination therapy with interferon (IFN) and ribavirin (RBV) was unsuccessful for improving cholestasis; however, the addition of DFPP to IFN and RBV alleviated cholestasis and improved renal function. Although IFN and RBV with DFPP could not eliminate HCV, results of liver function tests improved and remained stable for several months. This treatment with DFPP combined with IFN and RBV would be useful for resolving cholestasis due to FCH. Moreover, treatment of DFPP could improve liver and renal function test results and could stop the worsening condition of patients with FCH.

N,N-dimethylformamide (DMF) is a solvent used extensively in the chemical industry. The main toxic effect reported after exposure to DMF is hepatotoxicity. We encountered four patients with liver injury due to DMF exposure; the severity of the liver injury was related to the exposure levels. After removal of exposure, all patients recovered without specific treatment. A careful evaluation of occupational history is necessary when liver dysfunction develops in industrial workers.

We examined whether antigen-specific immune responses are lower in mice with protein energy malnutrition (PEM mice) compared with nourished (control) mice. The mechanisms underlying reduced antigen-specific immune responses of PEM mice were evaluated through analysis of the functional capacities of antigen-presenting dendritic cells (DC). PEM mice were produced by subjecting male C57BL/6 mice for 52 wk to a daily food intake equivalent to 70% of the mean amount consumed by the control mice that consumed food ad libitum. PEM mice and control mice were immunized with hepatitis B vaccine containing hepatitis B surface antigen (HBsAg) at 52 wk and humoral and cellular immune responses to HBsAg were evaluated at 58 wk. Lymphoproliferative assays were performed to assess the functional capacities of lymphocytes and DC. After 52 wk of food restriction, PEM mice had a 49% lower body weight than controls, almost no subcutaneous fat, severe muscle wasting, and atrophied spleen. All control mice developed antibodies to HBsAg (anti-HBs) in the sera and HBsAg-specific lymphocytes in the spleen as a result of immunization with the hepatitis B vaccine. PEM mice, however, were almost unresponsive to immunization with the hepatitis B vaccine. In PEM mice, the numbers of spleen DC, the T lymphocyte stimulatory capacities of DC, and their production of IL-12p70 and IFN-gamma was less than those of control mice (P < 0.05). We suggest that chronic undernutrition disrupts antigen-specific immune responses and that this disruption can be attributed at least in part to reduced frequencies and impaired functions of DC.

BACKGROUND AND AIMS: Autoimmune hepatitis (AIH) is an inflammatory disease of the liver that usually develops in middle-aged women. However, due to the increasing aging of the population and better diagnostic facilities, AIH is now diagnosed in older patients as well. This analysis compared the clinical and pathologic characteristics of older and middle-aged patients with AIH. PATIENTS AND METHODS: Thirteen older patients with AIH (mean age, 75.0+/-5.3 years; range, 70-89 years) and 27 middle-aged patients (mean age, 51.3+/-5.8 years; range, 41-60 years) were included in this study. In addition, the use of different treatment regimens, including prednisolone therapy and ursodeoxycholic acid (UDCA), was examined. RESULTS: There were no significant differences in gender, complications of other autoimmune diseases, and liver function tests between groups. However, the degree of hepatic fibrosis was significantly higher in older patients compared with middle-aged patients (P<0.05). Four patients with AIH in the older age group were successfully managed by UDCA alone. CONCLUSION: This study shows that older patients with abnormal liver function should be checked for AIH. In addition, UDCA may be an effective drug for management of older patients with AIH.

A case of malignant thymoma presenting as an anterior neck mass is reported. The tumor extended from the thyroid gland to the superior mediastinum. It did not accumulate Tc-99m pertechnetate, but continued to accumulate Tl-201 at the late phase. A fine-needle aspiration cytology from the tumor showed tight clusters of epithelial cells with crowded ovoid nuclei. The tumor was initially diagnosed as thyroid carcinoma, clinically and cytologically. A thymoma with a dominant epithelial component has to be considered in the differential diagnosis of a suspected papillary carcinoma of the thyroid.

A 39-year-old man was diagnosed with hepatitis B virus-related cirrhosis, and because of hepatic exacerbations with icterus and ascites, he had been repeatedly hospitalized. He was treated with lamivudine. Several months later, his ascites disappeared and his liver function was improved from class C to A according to the Child-Pugh classification. Two years later, one small hepatocellular carcinoma was detected, and he underwent a successful hepatectomy. From this case, we consider lamivudine to be useful for improving hepatic function in decompensated liver cirrhosis type B and lamivudine might enable surgical resection of hepatocellular carcinoma.

A 42-year-old Japanese man was admitted to our hospital for investigation of abnormal liver function tests. He had no history of drug use, and drank little alcohol. Body mass index was 30. Serum was negative for viral markers and autoantibodies. Laparoscopy revealed diffuse small nodules on the liver surface. Liver biopsy revealed small nodules with pericellular fibrosis and macrovesicular fat deposition throughout the acini. Some inflammatory changes were observed. Liver cirrhosis due to non-alcoholic steatohepatitis (NASH) was diagnosed. NASH displays similar histological and laparoscopic characteristics to alcoholic liver diseases.

Eicosapentaenoic acid (EPA), but not its metabolites (docosapentaenoic acid and docosahexaenoic acid), stimulated nitric oxide (NO) production in endothelial cells in situ and induced endothelium-dependent relaxation of bovine coronary arteries precontracted with U46619. EPA induced a greater production of NO, but a much smaller and more transient elevation of intracellular Ca2+ concentration ([Ca2+]i), than did a Ca2+ ionophore (ionomycin), EPA stimulated NO production even in endothelial cells in situ loaded with a cytosolic Ca2+ chelator 1,2-bis-o-aminophenoxythamine-N',N',N'-tetraacetic acid, which abolished the [Ca2+]i elevations induced by ATP and EPA, The EPA-induced vasorelaxation was inhibited by N-omega-nitro-L-arginine methyl ester. Immunostaining analysis of endothelial NO synthase (eNOS) and caveolin-1 in cultured endothelial cells revealed eNOS to be colocalized with caveolin in the cell membrane at a resting state, while EPA stimulated the translocation of eNOS to the cytosol and its dissociation from caveolin, to an extent comparable to that of the eNOS translocation induced by a [Ca2+]i-elevating agonist (10 muM bradykinin). Thus, EPA induces Ca2+-independent activation and translocation of eNOS and endothelium-dependent vasorelaxation. (C) 2001 Federation of European Biochemical Societies.

Sphingosylphosphorylcholine (SPC), a sphingolipid, concentration-dependently (1-50 mu M) induced contraction and slight elevation of the cytosolic Ca2+ concentration ([Ca2+](i)) in smooth muscle of the pig coronary artery, the result being a marked increase in the force/[Ca2+](i) ratio. In alpha-toxin- or beta-escin-permeabilized, but not Triton X-100-permeabilized, vascular strips, SPC induced contraction at constant [Ca2+](i) (pCa 6.3) in the absence of GTP, whereas a G-protein-coupled receptor agonist, histamine, required the presence of GTP to induce the contraction. The Rho-kinase blocker, Y-27632 (10 mu M) abolished the SPC-induced Ca2+-sensitization, without affecting the Ca2+-induced contraction. These results suggest that SPC induces Ca2+-sensitization of force in vascular smooth muscle, presumably through the activation of Rho-kinase (or a related kinase), (C) 2000 Federation of European Biochemical Societies.

肝は吸収した栄養素が最初に流れ込む臓器であり、体内における代謝の中心的な役割を果たす。そのため肝が機能不全に陥ると代謝異常を発症し、全身の臓器に影響を及ぼす。一方、進行した肝疾患患者はエネルギー消費量が亢進し、グリコーゲンの貯蔵量が低下するため糖質の燃焼比率が減り蛋白質や脂質の異化が増加し、低栄養状態となっている。そのため、これらの患者では栄養アセスメントを行い、栄養設定をして適切な栄養療法を行うことが求められている。また、分岐鎖アミノ酸(BCAA)やカルニチンなどの栄養素の投与や、就寝前エネルギー投与(LES)などの工夫により、栄養療法の効果を高めることができる。近年、生活習慣の欧米化や人口の高齢化により肥満やサルコペニアを合併した肝硬変患者が増加しており、それぞれの病態に応じた栄養療法が求められている。(著者抄録)

症例は82歳女性で、バセドウ病のため抗甲状腺剤内服中であったが、内服開始1年6ヵ月後より左眼の視野異常を自覚し、近医を受診するも原因不明であった。受診1ヵ月後には左眼視力低下も出現し、精査加療目的で当科紹介入院となった。臨床所見、MRI所見より、外眼筋腫大により圧迫性視神経症を呈した最重症甲状腺眼症と診断し、ステロイドパルス療法および放射線療法を開始した。ステロイドパルス療法1クール終了した時点で視力の改善と著明な視野の改善を認めたが、ステロイド糖尿病を発症した。強化インスリン療法を開始したところ、血糖レベルは徐々に改善し、経口糖尿病薬でコントロール可能となった。ステロイドパルス療法3クール施行後、プレドニゾロンの経口投与を開始し、軽快退院となった。3ヵ月経過した時点で、外眼筋の腫大は軽減し、視力・視野は良好に保たれているものの、不可逆性視神経障害が残存している。

症例は56歳女性。高血圧、2型糖尿病で通院中。糖尿病はグリメピリド3mg、メトホルミン750mgでHbA1c8〜9%であった。2011年10月に頭痛、吐気、食欲不振が出現し当院受診。画像検査でラトケ嚢胞と診断。ACTH、コルチゾール低下があり、症候性ラトケ嚢胞による中枢性副腎機能低下症と考えた。ヒドロコルチゾン補充を行い、続発性副腎不全による低血糖の危険性を考慮し経口血糖降下薬は中止したが、食前血糖値は70〜80mg/dLで推移した。その後病態の改善と共に血糖値の上昇がみられたが、リラグルチド0.3mgの投与により血糖値は良好に推移した。症候性ラトケ嚢胞は再燃する症例もあり、続発性副腎不全による低血糖の危険性を考慮した治療法が有用であると思われた。(著者抄録)
