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: Constipation is a common gastrointestinal symptom in patients with ulcerative colitis (UC). Several studies on the general population have demonstrated a link between allergic diseases and constipation. However, evidence regarding the association between allergic diseases and constipation in UC is limited. This study aims to evaluate this issue in Japanese patients with UC. METHODS: This cross-sectional study recruited consecutive 387 patients with UC. We used a self-administered questionnaire to estimate the prevalence of physician-diagnosed allergic diseases. The definition of constipation was based on Rome I criteria and/or medication for constipation. RESULTS: The prevalence of constipation was 12.5%. The prevalence rates of asthma, atopic dermatitis, pollen allergy, food allergy, and drug allergy were 11.8%, 9.0%, 36.3%, 6.2%, and 8.3%, respectively. Allergic diseases were not associated with constipation (adjusted odds ratio [OR] with asthma (adjusted OR 0.98 [95% confidence interval [CI] 0.27-2.80]), atopic dermatitis (adjusted OR 0.67 [95% CI 0.10-2.56]), pollen allergy (adjusted OR 0.92 [95% CI 0.41-1.97]), food allergy (adjusted OR 0.76 [95% CI 0.11-2.95]), and drug allergy (adjusted OR 1.06 [95% CI 0.28-3.24]). Additionally, the number of allergic diseases was not associated with the prevalence of constipation. CONCLUSIONS: In Japanese UC patients, no association between allergic diseases and constipation was found.

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.

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.

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.

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: 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.

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 incidence of inflammatory bowel disease (IBD) is increasing; hence, effective treatments are warranted. The therapeutic effect of human carbonic anhydrase I (hCA I) in IBD remains unknown. Therefore, we investigated whether oral tolerization to hCA I would induce antigen-specific protection from intestinal inflammation in vivo. Severe combined immunodeficient mice received hCA I, keyhole limpet hemocyanin (KLH), or phosphate-buffered saline (PBS) orally for 7 days. Colons and mesenteric lymph nodes (MLNs) were collected 4 weeks after cell transfer. Additionally, the mechanisms underlying the therapeutic effects were investigated. The comparison between the effects of well-established drugs and hCA I oral administration was investigated. Oral administration of hCA I ameliorated colitis remarkably. hCA I reached the cecum and ameliorated colitis more effectively than mesalazine and similarly to prednisolone. Compared with PBS treatment, hCA I treatment reduced interleukin (IL)-17a, IL-6, and retinoic acid-related orphan receptor gamma t (RORγt) expression in the colon or MLNs; moreover, hCA I markedly reduced IL-6, IL-17, and interferon-gamma (IFN-γ) levels in the MLN. Oral administration of hCA I induced immune tolerance and suppressed colitis in vivo. Thus, hCA I administration could be proposed as a new treatment option for IBD.

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.

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.

Background/Aims: Evidence regarding the association between body mass index (BMI) and functional dyspepsia (FD) in the Asian population is limited. Further, no study has evaluated this issue in young people in Asian and Western populations. Thus, we aim to investigate this issue among young Japanese people. Methods: The study subjects comprised of 8923 Japanese university students. BMI was divided into 4 categories (quartiles) on the basis of the study subjects' distribution (lowest, low, moderate, and high [reference]). The definition of lean, normal, overweight, and obese was BMI < 18.5 kg/m2, 18.5 ≤ BMI < 25 kg/m2 (reference), 25 kg/m2 ≤ BMI < 30 kg/m2, and 30 kg/m2 ≤ BMI, respectively. The definition of FD was based on the Rome III criteria. Results: The prevalence of FD was 1.9% in this cohort. The lowest BMI was independently associated with FD after adjustment (adjusted odds ratio [OR], 2.88; 95% confidence interval [CI], 1.46-3.67); P for trend = 0.001). The lowest BMI was independently associated with FD in women but not in men (OR, 2.94; 95% CI, 1.59-5.77; P for trend = 0.001). Leanness was independently associated with FD in total and in women but not in men (total: adjusted OR, 2.01; 95% CI, 1.40-2.86) and women (OR, 2.19; 95% CI, 1.35-3.45). However, interaction analysis showed no significant difference for sex. Conclusions: Among young Japanese people, BMI may be independently inversely associated with FD. Leanness may be an independent associated factor for FD in the young Japanese women.

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.

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.

Dietary palmitic acid (PA) promotes liver fibrosis in patients with nonalcoholic steatohepatitis (NASH). Herein, we clarified the intestinal absorption kinetics of dietary PA and effect of trans-portal PA on the activation of hepatic stellate cells (HSCs) involved in liver fibrosis in NASH. Blood PA levels after meals were significantly increased in patients with NASH compared to those in the control. Expression of genes associated with fat absorption and chylomicron formation, such as CD36 and MTP, was significantly increased in the intestine of NASH model rats compared with that in the controls. Plasma levels of glucagon-like peptide-2, involved in the upregulation of CD36 expression, were elevated in NASH rats compared with those in the controls. Furthermore, portal PA levels after meals in NASH rats were significantly higher than those in control and nonalcoholic fatty liver rats. Moreover, PA injection into the portal vein to the liver in control rats increased the mRNA levels associated with the activation of HSCs. Increased intestinal absorption of diet-derived PA was observed in NASH. Thus, the rapid increase in PA levels via the portal vein to the liver may activate HSCs and affect the development of liver fibrosis in NASH.

Background

The gut microbiota has potential implications in the pathogenesis of primary biliary cholangitis (PBC). However, little is known about the significance of small intestinal mucosa-associated microbiota (MAM) in PBC. We aimed to investigate the ileal MAM profile and identify its association with liver pathology in patients with PBC.
Methods

Forty-three patients with PBC and 24 healthy controls who underwent colonoscopy at our hospital between March 2018 and January 2020 were enrolled in a cross-sectional study. We performed 16S ribosomal RNA gene sequencing of MAM samples obtained from the mucosa of the terminal ileum of all subjects. We also examined the relationship between the abundance of ileal MAM and chronic nonsuppurative destructive cholangitis using liver specimens from patients with PBC.
Results

Dysbiosis of ileal MAM was observed in patients with PBC, with a characteristic overgrowth of <italic>Sphingomonadaceae</italic> and <italic>Pseudomonas</italic>. Multivariate analysis showed that the overgrowth of <italic>Sphingomonadaceae</italic> and <italic>Pseudomonas</italic> is an independent association factor for PBC. Moreover, the abundance of <italic>Sphingomonadaceae</italic> was associated with chronic nonsuppurative destructive cholangitis in PBC.
Conclusions

Overgrowth of <italic>Sphingomonadaceae</italic> and <italic>Pseudomonas</italic> in ileal MAM is an independent association factor for diagnosing PBC. <italic>Sphingomonadaceae</italic> may be particularly associated with the pathological development of PBC.

OBJECTIVE: Serum albumin is used as a marker of acute inflammation. Several studies have addressed the association between serum albumin and clinical outcome in patients with ulcerative colitis (UC). While mucosal healing (MH) has been indicated as the therapeutic goal for UC, the association between serum albumin and MH remains unclear. We evaluated this issue in patients with UC overall and explored whether duration of UC affected this association. DESIGN: This cross-sectional study recruited consecutive patients with UC. Study subjects consisted of 273 Japanese patients with UC. Serum albumin was divided into tertiles based on its distribution in all study subjects. One endoscopy specialist was responsible for measuring partial MH and MH, which were defined as a Mayo endoscopic subscore of 0-1 and 0, respectively. The association between serum albumin and clinical outcomes was assessed by multivariate logistic regression. RESULTS: Rates of clinical remission, partial MH and MH were 57.9%, 63% and 26%, respectively. Only high serum albumin (>4.4 mg/dL) was significantly positively associated with MH (OR 2.29 (95% CI: 1.03 to 5.29), p for trend=0.043). In patients with short UC duration (<7 years) only, high serum albumin was significantly positively associated with MH and clinical remission. In patients with long UC duration (≥7 years), in contrast, no association between serum albumin and clinical outcomes was found. CONCLUSION: In Japanese patients with UC, serum albumin was significantly positively associated with MH. In patients with short UC duration, serum albumin might be a useful complementary marker for MH.

BACKGROUND: Functional dyspepsia (FD) has a high prevalence worldwide and reduces patients' quality of life. The etiology of FD is likely multifactorial. Although two studies showed an inverse association between exercise habits and FD, evidence regarding the association between exercise habits and FD remains scarce. AIMS: This study aimed to investigate the association between exercise habits and FD among the young Japanese population, taking the presence or absence of an exercise partner as an additional variable. METHODS: The study subjects consisted of 8923 Japanese university students. The definition of FD was based on the Rome III criteria. Information on exercise frequency, exercise intensity, and exercise partners was obtained from a self-administered questionnaire. RESULTS: The prevalence of FD was 1.9% in this cohort. Low, moderate, and high frequency of exercise was independently inversely associated with FD (adjusted odds ratio [OR] was low: OR 0.69 [95% confidence interval (CI) 0.47-0.997], moderate: OR 0.53 [95% CI 0.34-0.81] and high: OR 0.53 [95% CI 0.30-0.88], p for trend p = 0.002). Moderate and high intensity of exercise was independently inversely associated with FD (moderate: OR 0.56 [95% CI 0.36-0.84] and high: OR 0.49 [95% CI 0.30-0.76], p for trend p = 0.001). Exercise with groups and with friends was independently inversely associated with FD whereas the association between exercising alone and FD was not significant (groups: OR 0.28 [95% CI 0.14-0.50] and friends: OR 0.44 [95% CI 0.24-0.74]). CONCLUSION: Among the young Japanese population, frequency and intensity of exercise may be independently inversely associated with FD. Additionally, exercise with groups and with friends but not by oneself was inversely associated with exercise and FD, respectively.

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.

BACKGROUND: Although the association between eating habits which can be modified and digestive diseases has been reported, to date, no research has evaluated the association between eating habits and ulcerative colitis (UC). Thus, we investigate the association between eating behavior and clinical outcome in Japanese patients with UC. METHODS: Eating quickly, eating until full, and skipping breakfast data was obtained from a self-administered questionnaire. Information on clinical outcome was collected from medical records. Mucosal healing (MH) and partial MH was defined as a Mayo endoscopic subscore of 0 or 0-1, respectively. Age, sex, BMI, current smoking, current drinking, prednisolone use, and anti-TNFα monoclonal antibody use were selected a priori as potential confounding factors. RESULTS: Study subjects consisted of 294 Japanese patients with UC. Eating at speed moderate and eating quickly were independently inversely associated with MH: the adjusted odds ratios (ORs) were 0.38 (95% confidence interval [CI] 0.16-0.85) and 0.38 (95% CI 0.17-0.81) (p for trend = 0.033). Eating until full was independently inversely associated with MH: the adjusted OR was 0.38 (95% CI 0.27-0.86). MH in patients who skipped breakfast was marginally lower than that in patients who did not skip breakfast. No association between eating habits and clinical remission or partial MH was found. CONCLUSION: Among patients with UC, eating rate and eating until full may be independently inversely associated with MH but not clinical remission.

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: Serum globulin is an inflammation marker. To date, no evidence regarding the association between serum globulin and disease activity in patients with ulcerative colitis has been reported. AIMS: We evaluated the association between serum globulin and endoscopic activity in patients with ulcerative colitis. METHODS: Serum globulin was divided into tertiles based on the distribution of study subjects (low globulin, ≤ 2.7 g/dl (reference); moderate globulin, 2.7-3.1 g/dl; and high globulin, > 3.1 g/dl). A single endoscopic specialist evaluated the endoscopic findings, and mucosal healing was based on Mayo endoscopic subscore. RESULTS: A total of 277 patients with ulcerative colitis were included in the study. Serum globulin was independently positively associated with diminished or absent vascular markings [moderate: adjusted odds ratio (OR) 3.70 (95% confidence interval, CI: 1.82-7.88) and high: adjusted OR 2.40 (95%CI: 1.20-4.94), p for trend = 0.005]. A similar positive association between globulin and erosion was found [high: adjusted OR 2.00 (95%CI: 1.05-3.86)]. Serum globulin was independently inversely associated with mucosal healing [moderate: adjusted OR 0.37 (95%CI: 0.18-0.73) and high: adjusted OR 0.31 (95%CI: 0.14-0.64), p for trend = 0.001] and adjusted partial mucosal healing [moderate: OR 0.51 (95%CI: 0.26-0.98), p for trend = 0.048]. The inverse association between globulin and mucosal healing was significant in the low but not the high C-reactive protein group. CONCLUSIONS: In patients with ulcerative colitis, serum globulin was significantly positively associated with endoscopic activity, and was significantly inversely associated with mucosal healing, especially in the low C-reactive protein group.

PURPOSE: Bilirubin is known to have antioxidant effects. Several pieces of evidence regarding association between serum bilirubin and UC exist. Three studies found that serum bilirubin was inversely associated with severity of ulcerative colitis (UC), but no evidence regarding an association between serum bilirubin and mucosal healing (MH) has yet been shown. Thus, we evaluated this issue among Japanese patients with UC. METHODS: The study subjects consisted of 304 Japanese patients with UC. Serum total bilirubin and indirect bilirubin were divided into quartiles on the basis of the distribution of all study subjects (low, moderate, high, and very high). Several endoscope specialists were responsible for evaluating MH, which was defined as a Mayo endoscopic subscore of 0. The information on clinical remission was collected using medical records. RESULTS: The mean age was 49.9 years, the percentage of male patients was 59.2%, and the percentage of MH was 29.3%. High serum total bilirubin was independently positively associated with MH (OR 2.26 [95%CI 1.13-4.61]. However, after adjustment for confounding factors, the association between total bilirubin and MH disappeared. Very high serum indirect bilirubin was independently positively associated with MH (OR 2.31 [95%CI 1.10-5.00], p for trend = 0.026). No association between bilirubin and clinical remission was found. CONCLUSIONS: Among Japanese patients with UC, serum indirect bilirubin, but not total bilirubin, was significantly positively associated with MH but not clinical remission.

BACKGROUND: Epidemiological evidence on the association between physical activity (PA) and ulcerative colitis (UC) is limited, and the effect of PA on the prognosis of UC is currently unknown. We evaluated the association between PA and clinical outcomes, including clinical remission and mucosal healing (MH), in Japanese patients with UC. METHODS: The study subjects were 327 Japanese patients with UC. Subjects were asked about the average time spent per day on 4 types of PA (sedentary, standing, walking, and strenuous activity) and metabolic equivalents (METs) using a validated questionnaire. Clinical outcomes were complete MH, MH, and clinical remission. The association between PA, including hours spent on each type of PA and average daily METs, and clinical outcomes was assessed by multivariate logistic regression. RESULTS: Plentiful strenuous activity was significantly inversely associated with MH and complete MH after adjustment (MH: adjusted odds ratio [OR] 0.45, 95% confidence interval [CI] 0.23-0.89; complete MH: adjusted OR 0.24, 95%CI 0.07-0.62; P for trend=0.008). A very high daily MET total was significantly inversely associated with complete MH after adjustment (adjusted OR 0.37, 95%CI 0.16-0.80; P for trend=0.010). In contrast, no association between PA and clinical remission was found (plentiful strenuous activity: adjusted OR 1.10, 95%CI 0.55-2.23; very high daily total METs: adjusted OR 0.74, 95%CI 0.37-1.46). CONCLUSION: In Japanese patients with UC, time spent per day on strenuous activity and total PA per day may be significantly inversely associated with complete MH, but not with clinical remission.

BACKGROUND: Mucosal healing (MH) has been indicated as the therapeutic goal for ulcerative colitis (UC). Platelet count is known as an inflammation evaluation. However, the association between platelet count and MH among patients with UC is still scarce. We therefore assessed this issue among Japanese patients with UC. METHODS: The study subjects consisted of 345 Japanese patients with UC. Platelet count was divided into quartiles on the basis of the distribution of all study subjects (low, moderate, high, and very high). Several endoscope specialists were responsible for evaluating MH and partial MH, which was defined as a Mayo endoscopic subscore of 0 and 0-1, respectively. Estimations of crude odds ratios (ORs) and their 95% confidence intervals (CIs) for partial MH and MH in relation to platelet count were performed using logistic regression analysis. Age, sex, CRP, steroid use, and anti-Tumor necrosis factor α (TNFα) preparation were selected a priori as potential confounding factors. RESULTS: The percentage of partial MH and MH were 63.2 and 26.1%, respectively. Moderate and very high was independently inversely associated with partial MH (moderate: OR 0.40 [95%CI 0.19-0.810], very high: OR 0.37 [95%CI 0.17-0.77], p for trend = 0.034). Similarly, moderate, high, and very high were independently inversely associated with MH (moderate: OR 0.37 [95% CI 0.18-0.73], high: OR 0.41 [95% CI 0.19-0.83], and very high: OR 0.45 [95% CI 0.21-0.94], p for trend = 0.033) after adjustment for confounding factors. CONCLUSIONS: Among patients with UC, platelet count was independently inversely associated with MH.

Schistosomiasis infection is a major cause of morbidity and mortality in endemic areas. Developed countries have declared that schistosomiasis has been eradicated; however, residents of these countries may travel and stay in endemic areas and the number of foreign travelers is increasing in the recent years. Thus, schistosomiasis is regarded as an imported infection. Ultrasonography and serum antibody titer tests are well established as diagnostic methods for schistosomiasis. However, a definitive diagnosis cannot be obtained using these tests in some cases. We herein report a case in which schistosomiasis was confirmed based on laparoscopic liver biopsy without a definitive diagnosis by blood test, fecal examination, or imaging.

A 65-year-old woman was admitted with fever, abdominal pain, and laboratory markers indicating an inflammatory reaction. An abdominal ultrasound (US) showed a 60-mm hyperechoic lesion in the left lateral segment of the liver diagnosed as a liver abscess. Antibiotics were administered. Percutaneous drainage was attempted but was difficult because of poor liquefaction. On day 6, the abscess had enlarged and progressed to involve the medial segment. Hypermucoviscous Klebsiella pneumoniae was detected in blood and abscess cultures. Repeat US showed poor liquefaction, suggesting that percutaneous drainage would again fail. As the abscess was deemed resistant to medical treatment, a left hepatic lobectomy was performed. Postoperatively, the pa-tient’s general condition and inflammatory reaction quickly improved. Hypermucoviscous K. pneumoniae is often resistant to antibiotics because of the organism’s extremely mucoid capsule. Percutaneous drainage is also difficult, so surgical resection should be considered.

OBJECTIVES: In the general population, late-night dinner is positively associated with gastroesophageal reflux disease (GERD). No evidence exists regarding the relationship between eating behaviours and GERD in patients with type 2 diabetes mellitus, though the prevalence of GERD in patients with type 2 diabetes is higher than in those without diabetes. We conducted this study to investigate the association between eating behaviours and GERD in Japanese patients with type 2 diabetes. METHODS: The study's subjects were 817 Japanese patients with type 2 diabetes. GERD was defined as being present when a subject had a Quality of Life and Utility Evaluation Survey Technology (QUEST) score of 4 or higher. The assessment of eating behaviour was performed by self-administered questionnaire. Subjects were considered positive for late-night dinner if they answered yes to the question "Do you eat dinner within 2 hours before bedtime at least 3 times per week? RESULTS: The prevalence values of GERD, skipping breakfast, bedtime snacking, late-night dinner and fast eating were 32.0%, 13.7%, 27.1%, 28.8%, and 44.4%, respectively. Late-night dinner was independently positively associated with GERD in patients with type 2 diabetes; the adjusted odds ratio was 1.46 (95% CI 1.03 to 2.05). No relationships were found between skipping breakfast, bedtime snacking or fast eating and GERD. CONCLUSIONS: Late-night dinner may be positively associated with GERD in Japanese patients with type 2 diabetes.

Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) is often associated with type 1 autoimmune pancreatitis, and the frequency of isolated IgG4-SC seems to be quite low, making the diagnosis of isolated IgG4-SC challenging. A 63-year-old male was admitted to our hospital for frequent fever. Abdominal magnetic resonance cholangiopancreatography showed diffuse narrowing of the common bile duct and post-stenotic dilatation of the right posterior bile duct. Laboratory tests showed abnormalities in the levels of hepatobiliary enzymes and serum IgG4 levels. Endoscopic retrograde cholangiopancreatography showed diffuse narrowing of intrahepatic bile ducts and post-stenotic dilatation of the right posterior bile duct but no abnormalities in the pancreas. Intraductal ultrasonography showed symmetric circumferentially thickened walls of both narrowed and non-narrowed common bile ducts. Histologic examination of the common bile duct mucosa showed infiltration of IgG4-positive plasma cells. Laparoscopic observations showed discoloration with red lobular markings and multiple small depressed lesions. Liver histology showed mild cholangitis with infiltration of IgG4-positive plasma cells around the bile ducts. From these findings, the patient was diagnosed with isolated IgG4-SC. After treatment with a steroid, bile duct dilatations improved. Laparoscopy and intraductal ultrasonography were useful to diagnose isolated IgG4-SC.

We herein report a 55-year-old woman who presented with erythema and bilateral hilar lymphadenopathy 4 months prior to the detection of pancreatic lesions on an ultrasound. A skin biopsy showed evidence of sarcoidosis. The largest lesion in the tail of the pancreas was hypoechoic on endoscopic ultrasonography (EUS). The lesion was initially iso-enhanced on contrast enhanced-EUS (CE-EUS) but subsequently became hypoenhanced. The lesion revealed heterogeneous components of both soft and hard tissue on EUS elastography. She was ultimately diagnosed with pancreatic sarcoidosis based on the presence of noncaseating granulomas seen on pancreatic tissue retrieved through an EUS-guided fine needle aspiration biopsy.

AIM: Assessing disease progression in patients with primary biliary cholangitis (PBC) is necessary in order to evaluate therapeutic effectiveness. Therefore, the aims of this study were to evaluate both the diagnostic accuracy of both real-time tissue elastography (RTE) and vibration-controlled transient elastography (VCTE), and the usefulness of hepatic and splenic elasticity as predictive markers for the progression of symptomatic PBC. METHODS: The study participants were 44 patients with PBC. We assessed hepatic and splenic elasticity using RTE and VCTE and measured serum markers related to fibrosis and hepatic and splenic blood flow using Doppler ultrasonography. We then compared RTE and VCTE for diagnostic accuracy. Patients with asymptomatic PBC were followed every 1-3 months. RESULTS: Both RTE and VCTE performed well and had superior diagnostic accuracy compared with biochemical markers. The areas under the receiver operating characteristic curve for RTE and VCTE were 0.92 and 0.92, 0.95 and 0.91, and 0.97 and 0.91 for F ≥ 2, F ≥ 3, and F = 4, respectively. During follow-up, nine patients (25.0%) developed liver-related symptoms. Multivariate analysis revealed that splenic elasticity assessed using RTE was a significant independent factor for the development of liver-related symptoms (odds ratio, 2.19; P = 0.024). CONCLUSIONS: Real-time tissue elastography offered better diagnostic accuracy for severe fibrosis and cholangitis than VCTE. Splenic elasticity determined using RTE is a useful parameter for evaluating liver-related symptoms and an effective predictive marker of disease progression in patients with asymptomatic PBC.

BACKGROUND: Palmitic acid is an important risk factor for the pathogenesis of non-alcoholic steatohepatitis (NASH), but changes in palmitic acid intestinal absorption in NASH are unclear. The aim of this study was to clarify changes in palmitic acid intestinal absorption and their association with the pathogenesis of NASH. METHODS: A total of 106 participants were recruited to the study, of whom 33 were control subjects (control group), 32 were patients with NASH Brunt stage 1-2 [early NASH (e-NASH)], and 41 were patients with NASH Brunt stage 3-4 [advanced NASH (a-NASH)]. 13C-labeled palmitate was administered directly into the duodenum of all participants by gastrointestinal endoscopy. Breath 13CO2 levels were measured to quantify palmitic acid absorption, and serum Apolipoprotein B-48 (ApoB-48) concentrations were measured after a test meal to quantify absorbed chylomicrons. Expressions of fatty acid (FA) transporters were also examined. The associations of breath 13CO2 levels with hepatic steatosis, fibrosis and insulin resistance was evaluated using laboratory data, elastography results and liver histology findings. RESULTS: Overall, 13CO2 excretion was significantly higher in e-NASH patients than in the control subjects and a-NASH patients (P < 0.01). e-NASH patients had higher serum ApoB-48 levels, indicating increased palmitic acid transport via chylomicrons in these patients. Jejunal mRNA and protein expressions of microsomal triglyceride transfer protein and cluster of differentiation 36 were also increased in both NASH patient groups. The 13CO2 excretion of e-NASH patients was significantly correlated with the degree of hepatic steatosis, fibrosis and insulin resistance (P = 0.005, P < 0.001, P = 0.019, respectively). CONCLUSIONS: Significantly upregulated palmitic acid absorption by activation of its transporters was evident in patients with NASH, and clinical progression of NASH was related to palmitic acid absorption. These dietary changes are associated with the onset and progression of NASH.

A 58-year-old man was diagnosed with advanced hepatocellular carcinoma with portal vein tumor thrombosis (PVTT). The tumors were multiple and existed in both lobes. Drug-eluting beads transcatheter arterial chemoembolization (DEB-TACE) was performed for the tumors in the left lobe. Embosphere and Hepasphere were selected for embolization of the arterioportal shunt, followed by loaded epirubicin infusion into the left hepatic artery. Computed tomography showed reduction of PVTT. However, liver failure progressed, and the patient died 67 days after DEB-TACE. Autopsy showed that the beads reached the tumor thrombosis in the portal vein. The prognosis of hepatocellular carcinoma with PVTT is poor. Although there are no established treatments for unresectable PVTT, DEB-TACE might be a useful option for such cases.

BACKGROUND: It remains unclear whether fatty liver is a risk factor for the onset of abnormal glucose tolerance in any patient. The objective of this study was to clarify the relationship between fatty liver and the onset of impaired fasting glucose according to baseline fasting plasma glucose (FPG) levels. METHODS: This community-based longitudinal cohort study included 7,905 adults (3,863 men, 4,042 women; age range, 18-80 years) who had at least two annual checkups between 2003 and 2013. Those with FPG levels ≥110 mg/dl, taking anti-diabetic agents, and/or testing positive for hepatitis B surface antigen or anti-hepatitis C virus antibody were excluded, leaving 7,203 participants eligible for inclusion. All participants were divided into quartiles derived from their FPG levels at baseline. FPG ≥110 mg/dl during the observation period was defined as onset of IFG. RESULTS: Onset of IFG was found in 7.7 % of men and 2.1 % of women (p < 0.001). After adjusting for age, body mass index, systolic blood pressure, triacylglycerol, high-density lipoprotein cholesterol, uric acid, creatinine, family history of diabetes, alcohol consumption, and current smoking, a positive association was found between fatty liver and the onset of IFG in both sexes with the highest quartile of FPG levels [men: adjusted hazard ratio (aHR) 1.823, 95 % confidence interval (CI) 1.316-2.534, p < 0.001; women: aHR 2.016, 95 % CI 1.117-3.6, p = 0.02]. CONCLUSIONS: Our results suggest that fatty liver is independently associated with an increased risk of developing IFG in individuals with high FPG.

Fontan術後の長期経過中に、Fontan循環に起因し肝線維化の進展と肝細胞癌の発症をきたすFontan術後肝合併症(Fontan-associated liver disease:FALD)が近年注目されている。FALD症例で肝線維化診断のため肝生検を施行した報告は少数ながらみられるが、腹腔鏡を施行し、肝の形態と組織評価の両方を行っている報告は無い。今回我々は腹腔鏡検査を施行しFALDを診断しえた3例を経験した。症例は34歳男性、33歳男性、25歳女性で、それぞれFontan術後から23年、17年、17年であった。腹腔鏡検査にて全例結節肝の所見であった。鬱血肝に対する肝生検では術後出血に注意する必要があるが、腹腔鏡では腹腔内出血の有無を詳細に観察可能であり、今回肝生検を施行した全例で出血が無く終了できた。肝組織所見は、中心静脈周囲を中心とした線維形成がみられ、鬱血による線維化進展に矛盾しない所見であった。Fontan術後症例では安全かつ確実な診断を行うためには従来の超音波ガイド下生検よりも腹腔鏡検査での施行が望ましい。FALDは術後経過により肝線維化が進展し肝発癌の高危険群になると考えられ、定期的な画像検査が必要である。(著者抄録)

BACKGROUND: Only limited epidemiological evidence exists regarding the relationship between age and gastroesophageal reflux disease (GERD) among Japanese patients with type 2 diabetes mellitus. AIM: The purpose of the present study is to investigate this issue among Japanese patients with type 2 diabetes mellitus. METHODS: A multicenter cross-sectional study was conducted in 847 Japanese patients with type 2 diabetes mellitus. Subjects were divided into quartiles according to age: (1) 19 ≤ age < 56, (2) 56 ≤ age < 64, (3) 64 ≤ age < 71, and (4) 71 ≤ age < 89. GERD was defined as present when a subject had a Carlsson-Dent self-administered questionnaire (QUEST) score ≥4. RESULTS: The prevalence of GERD was 31.5 %. Younger age was independently associated with a higher prevalence of GERD: the adjusted odds ratios (95 % confidence intervals) for GERD in relation to age < 56, 56 ≤ age < 64, 64 ≤ age < 71, and ≥71 were 3.73 (2.16-6.53), 1.98 (1.21-3.27), 1.66 (1.05-2.68), and 1.00 (reference), respectively (P for trend = 0.001). Among 201 patients with PPI or histamine H2-receptor antagonist (H2RA), less than 56 years of age was independently positively associated with GERD: the adjusted OR was 5.68 (95 % CI 1.55-22.18) (P for trend = 0.02). CONCLUSIONS: Younger age may be independently positively associated with GERD among Japanese type 2 diabetes mellitus patients, regardless of the use of PPI or H2RA.

BACKGROUND: Fatty liver disease is associated with glucose intolerance and hepatic insulin resistance. However, there are distinct etiologies for alcoholic versus non-alcoholic fatty liver disease (NAFLD), and it is unknown whether alcohol consumption influences the onset of glucose intolerance in fatty liver disease patients. Therefore, we investigated the relationship between fatty liver disease and the onset of impaired fasting glucose (IFG) with respect to alcohol consumption. METHODS: The records of 6804 Japanese subjects were reviewed to identify those meeting the criteria for IFG. Male and female subjects were classified into five and four groups, respectively, based on average alcohol consumption (g/week). IFG onset was defined as fasting plasma glucose levels ≥110 mg/dl. RESULTS: In the non-drinker, >0-70 g/week, >70-140 g/week, >140-210 g/week (men only), and >210 g/week (men only) or >140 g/week (women only) groups, 7.3, 6.7, 6.4, 9, and 6.4 % of men and 2, 1.7, 3.1, and 3.2 % of women, respectively, developed IFG. Fatty liver was positively associated with the onset of IFG in men of the >0-70 g/week group (adjusted hazard ratio [aHR], 2.808; 95 % confidence interval [CI] 1.605-5.049, p < 0.001) and women of the >70-140 g/week group (aHR, 4.193; 95 % CI, 1.036-14.584, p = 0.045) after adjusting for previously reported IFG risk factors. No associations were observed in the other groups. CONCLUSIONS: A small amount of alcohol consumption is a significant risk factor for the onset of IFG in NAFLD patients; onset risk differs according to the amount of alcohol consumption.

BACKGROUND: Carbonic anhydrase I (CA I), a major cecal bacterial antigen, improves inflammatory bowel disease (IBD) symptoms in a murine model. The aim of this study was to identify the responsible epitope region within the CA I protein and evaluate its effect on inflammation using a murine IBD model. METHODS: Candidate peptides within the CA I protein sequence that interact with major histocompatibility complex class II were chosen and their immune responses were evaluated using mesentery lymph nodes (MLNs) from a CD4CD25 T-cell transfer murine colitis model. Mice were treated with regulatory dendritic cells (Reg-DCs)-pulsed CA I peptide. We assessed their clinical signs, histopathology, induction of cytokines and transcription factors, and generation of CD103CD11c dendritic cells and regulatory T cells (Tregs). RESULTS: We identified 4 candidate epitope peptides of CA I. Among these, Reg-DCs pulsed with CA I 58-73 peptide (Reg-DCsCA I 58-73) alone ameliorated colitis. Reg-DCsCA I 58-73-treated mice showed higher mRNA expression levels of forkhead box protein 3, aldehyde dehydrogenase family 1a2, transforming growth factor-β, and interleukin (Il)10, when compared with lower mRNA expression of retinoic acid-related orphan receptor gamma and Il17a in MLNs. Compared with control mice, these mice also showed higher numbers of Foxp3CD4CD25 Tregs and CD103CD11c dendritic cells in MLNs and colon. Administration of Reg-DCsCA I 58-73 induced antigen-specific Tregs in MLNs of colitic mice. CONCLUSIONS: CA I 58-73 peptide induces antigen-specific therapeutic effect in a murine IBD model using Reg-DCs, indicating that CA I 58-73 is a candidate epitope for IBD immunotherapy.

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.

A 50-year-old man with chronic HCV infection had been received the injections of 12MU of Consensus-Interferon (C-IFN) three times a week in a previous hospital. Six months later, C-IFN therapy was terminated because of fever and massive ascites. Diuretics and antibiotics had not been effective against these symptoms. In the meantime, skin symptoms of purpura and giant ulcers in the extremities developed, and he was transferred to our hospital. Because skin biopsy revealed vasculitis and serum MPO-ANCA was positive, the diagnosis of ANCA associated vasculitis was made. Methylpredonizoron pulse therapy improved skin symptoms and massive ascites, and the skin ulcers eventually disappeared. ANCA is suggested to be responsible for this rare complication.

Hepatitis-associated aplastic anemia (HAA) has been reported to show a successful outcome following immunosuppressive treatment. On the other hand, the long-term prognosis of HAA has not been sufficiently clarified. Herein we report a patient with HAA who had been treated with cyclosporine for one year, and maintained complete remission without treatment. Ten years later, acute non-A, non-B, and non-C hepatitis reccurred followed by bone marrow aplasia. A second immunosuppressive treatment with antithymocyte globulin and cyclosporine was effective. This case might provide useful information for the long-term follow-up of patients with HAA.

A 69 years old man was admitted to our hospital for further examinations of the liver tumor October, 2003. No underlying liver disease was found. Two tumors in the liver, 2cm in diameter respectively, were detected by abdominal ultrasonography and MRI scan. Ultrasonogram-guided needle biopsy from the liver tumor showed diffuse infiltration of CD20 positive, small lymphocytes. A distinct single band demonstrating clonal JH gene rearrangement was detected by southern blot analysis using tissues by needle biopsy. Thus, the patient was diagnosed with primary hepatic MALT lymphoma in the normal liver. These tumors were treated with percutaneus radiofrequency ablation (RFA), followed by Rituximab administration. No relapse has been noted until September, 2005.

BACKGROUND: Motilin and ghrelin have been recognized as important endogenous regulators of gastrointestinal motor function in mammals, mediated respectively by the motilin receptor and by the closely related ghrelin receptor. The aims of this study were to explore the distribution of motilin and ghrelin receptors along the human gastrointestinal tract and to establish the molecular nature of the human motilin receptor. METHODS: Post mortem and surgical human tissue specimens with no hemorrhage, necrosis, or tumor were obtained from various parts of the gastrointestinal tract. We analyzed levels of expression of mRNA for motilin and ghrelin receptors and examined their molecular identities. Portions of some specimens were also studied by immunohistochemistry for expression of the motilin and ghrelin receptor. RESULTS: The long form of the motilin receptor, but not the short form, was expressed in all parts of the gastrointestinal tract, and expressed at higher levels in muscle than in mucosa. Motilin receptor immunoreactivity was present in muscle cells and the myenteric plexus, but not in mucosal or submucosal cells. In contrast, ghrelin receptor mRNA was expressed equally in all parts of the gastrointestinal tract, with similar levels of expression in mucosal and muscle layers. CONCLUSIONS: Both the motilin and ghrelin receptors are expressed along the human gastrointestinal tract, but they have clearly distinct distributions in regard to both level and layer. The diffuse muscle expression of the motilin receptor, at both the levels of the gene and the protein product, along the entire gastrointestinal tract makes it a useful potential target for motilide drugs for dysmotility.

We investigated the alteration of nutritional status in 144 patients who were treated for the first time with endoscopic sclerotherapy or endoscopic variceal ligation during their therapies. The serum levels of albumin, cholinesterase and total cholesterol were compared before and after treatment. The serum level of cholinesterase declined significantly. To investigate the impact of aging on the changes of nutritional status we divided all patients into two groups: (1) under 65 years, and (2) over 65 years. The decline of serum albumin of elderly patients (n=65) was significantly greater than that of younger patients (n=79). A branched-chain amino acid (BCAA)-enriched nutrient mixture for nutritional treatment significantly suppressed the decline of serum albumin in elderly patients. Nutritional treatment with a BCAA-enriched nutrient mixture should be considered during endoscopic therapy for esophageal varices, especially in elderly patients.

BACKGROUND: Variceal bleeding is a common, life-threatening complication of primary biliary cirrhosis (PBC). Recently, several reports have suggested that the existence of esophageal varices in patients with PBC is a significant factor in the assessment of disease prognosis. However, there have been no reports on the recurrence of esophageal varices following treatment in patients with PBC. In this study, we investigated the recurrence of esophageal varices in PBC patients and attempted to identify predictive factors for the recurrence of esophageal varices. METHODS: Between April 1993 and August 2003, 138 patients with esophageal varices who had been treated by endoscopic variceal ligation (EVL; 96 men and 42 women; age, 33-83 years; mean, 62.6 +/- 10.1 years), were enrolled in the present study. The diagnosis of esophageal varices was made by upper gastrointestinal endoscopy, and the varices were graded according to the criteria of the Japanese Research Society for Portal Hypertension. The relationship between the recurrence of esophageal varices and factors such as biochemical and hematological parameters, as well as the etiology of the liver disease, was analyzed using the Kaplan-Meier method and the multivariate Weibull regression model. RESULTS: PBC patients had an earlier recurrence of esophageal varices compared to non-PBC patients, and two factors, prothrombin time and etiology (PBC/non-PBC), were indicative of significantly earlier recurrence of esophageal varices. CONCLUSIONS: We should be extra careful in the follow-up of patients with PBC after therapy for esophageal varices.

A 75-year-old male was diagnosed to have a gastric polyp by routine uppergastrointestinal endoscopy in 1985. The lesion was located on the greater curvature of the antrum of the stomach. Histological examination of biopsy specimens showed hyperplastic polyp. In 1995, polypectomy was performed, because histological examination of biopsy specimens revealed Group IV prior to the treatment. Pathologically, the lesion was diagnosed as well differentiated adenocarcinoma. In this study we report a case of early gastric cancer arising from a hyperplastic polyp.

Endoscopic injection sclerotherapy (EIS) is a very potent therapy for esophageal varices. However, its effect can only be achieved if done by an experienced endoscopist. It is difficult to ensure the placement of needle at varices for sufficient duration using the present therapeutic regimen. This is mainly due to an involuntary movement of the esophagus. As it is difficult to fix the endoscope at a variceal point, the needle may be fallen off even after entering into the varices. The aims of the study was to develop a new device for EIS so that the following purposes can be achieved
1) proper maintenance of expanded visual field, 2) fixation of the endoscope at a vaiceal point. We modified a commercially-available straight type of transparent hood. We made a concave groove in this hood measuring 6.5 x 5.0 mm. This groove was adjusted to the endoscope so that it remains at 8 O'clock position. The groove of the hood remain aligned to the variceal point perfectly after the entry of the endoscope. Then 5% ethanolamine oleate iopamidol (EOI) was injected into the varix. EIS using this new device showed better therapeutic effects. For example, it was possible to introduce EOI in 89% of the supplying vessels by this new device compared to 30% by the previous method (p&lt
0.05). This new device is cheap, easy to use, has no complication and ensures better EIS.

Background Primary biliary cirrhosis (PBC) is usually classified as either asymptomatic PBC (a-PBC) or symptomatic PBC (s-PBC). Although the proportion of a-PBC versus s-PBC patients has been consistently increasing, it is not clear whether the present criteria for the staging of PBC are optimal or not. We investigated the clinical stage of PBC patients from the standpoint of esophagogastric varices (EGV). Methods. One hundred and nine PBC patients were enrolled in this retrospective study. We investigated the clinical features of PBC based on laboratory data, histological stage, symptoms, and existence of EGV. In addition, the clinical course and prognosis in patients who were periodically followed up were also studied. Results. (1) EGV was detected in a-PBC patients, and there was no difference in the grade of EGV between a-PBC and s-PBC patients. (2) a-PBC patients with EGV had more liver damage than those without EGV, and a-PBC patients with EGV had a poorer prognosis than those without EGV. (3) Three of 11 patients who progressed from a-PBC to s-PBC within 3 years had EGV. (4) One of 3 a-PBC patients with EGV had progressed to s-PBC at 3-year follow-up. Conclusions. These results indicate that EGV is one of the most important factors for evaluating PBC. Therefore, we would like to propose that a-PBC patients with EGV should either be included in the presently defined s-PBC class, or that new prognostic classes of PBC be created that include EGV as a prognostic factor.

難治性腹水に対する治療法の一つにTransjugular intrahepatic portosystemic shunt(TIPS)がある。TIPSにおける短絡路は多くの場合、右肝静脈と門脈右枝もしくは後区域枝との間に作成される。今回、右肝静脈が低形成のため右肝静脈からのTIPSが困難な症例に対し、経大腿静脈アプローチで副肝静脈から門脈右枝に短絡路を作成するという方法でTIPSを行った。症例は50代男性で、短絡路作成は安全に施行でき成功したが、大量腹水の十分な減量にはつながらなかった。

A 21-year-old man with an 8-year history of acquired immunodeficiency syndrome (AIDS) presented with abdominal pain, jaundice and dark urine. Laboratory data on admission revealed cholestasis. The total bilirubin concentration was 10.0 mg/dL. Alanine transaminase and aspartate transaminase were 198 IU/L and 195 IU/L, respectively. The serum alkaline phosphatase level was 2724 IU/L. γ-Glutamyl transferase was 1770 IU/L. Abdominal ultrasonography and computed tomography revealed dilation of the common bile duct and intrahepatic ducts without gallstones. Endoscopic retrograde cholangiopancreatography showed dilation of the common bile duct up to the level of the ampulla of Vater with partial stenosis. Endoscopic sphincterotomy was performed. The abdominal pain and jaundice resolved immediately and the liver function tests were significantly improved. The patient developed a subarachnoid hemorrhage and died of respiratory arrest 2 months after the endoscopic sphincterotomy.

A 20-years-old female was admitted to our hospital with a history of fever for four weeks. She also complained of upper abdominal pain. Laboratory tests suggested the existence of severe inflamation. Abdominal ultrasonography revealed only a hyper echoic shadow between the liver and the abdominal wall. The patient was diagnosed to have Fitz-Hugh-Curtis syndrome due to the presence of Anti-Chlamydia trachomatis anti-body, a hyperechoic shadow between the liver and the abdominal wall by abdominal ultrasonography and abdominal pain. Even, after conservative therapy, her abdominal pain was not disappeared, so we decided to perform laparoscopy for assessing both the existence and the severity of the adhesion. Laparoscopic examination revealed the existence of, so called, &quot;violin string adhesions&quot; between the anterior wall of the liver capsule and the abdominal wall, and Chlamydia trachomatis antigen in ascitic fluid was positive. The clearance of adhesion let to relieve her abdominal pain. In conclusion, a diagnosis of Fitz-Hugh-Curtis syndrome should be considered in femele patients presenting with upper abdominal pain without any apparent causes. Laparoscopy appears to be beneficial not only for the diagnosis but also therapy in patients with Fitz-Hugh-Curtis syndrome.
