Background and Aim: Although oral mesalamine is the first‐choice drug for treating mild‐to‐moderate ulcerative colitis (UC), some patients show symptoms of intolerance, including exacerbation of diarrhea and abdominal pain. The present study clarified the current state and clinical courses of patients with mesalamine intolerance. Methods: Patients who were diagnosed with UC and administered oral mesalamine at eight hospitals in Japan with a follow‐up period exceeding 1 year were analyzed. Results: Sixty‐seven (11%) of 633 patients showed intolerance to at least one formulation of oral mesalamine. The frequency of mesalamine intolerance has increased in recent years, rising from 5.3% in 2007–2010 to 9.1% in 2011–2013 and 16.2% in 2014–2016. The most common complications were the exacerbation of diarrhea (n = 29), a fever (n = 25), and abdominal pain (n = 22). Readministration of mesalamine/sulfasalazine was attempted in 43 patients, mostly with other types of formulation of mesalamine, and more than half of these patients proved to be tolerant. The risk factors for mesalamine intolerance were female gender (odds ratio [OR] = 1.83; 95% confidence interval [CI], 1.08–3.12), age < 60 years old (OR = 2.82; CI, 1.19–8.33), and pancolitis (OR = 2.09; 95% CI, 1.23–3.60). There were no significant differences in the use of anti‐tumor necrosis factor‐α agents, colectomy, or steroid‐free remission at the last visit between patients with and without mesalamine intolerance. Conclusions: Mesalamine intolerance is not rare, and its frequency has been increasing recently. The prognosis of patients with mesalamine intolerance did not differ significantly from that of those without intolerance. [ABSTRACT FROM AUTHOR]

Background and Aim: Bleeding is an inevitable and often severe complication after endoscopic sphincterotomy (EST). We aimed to investigate the factors associated with post‐EST bleeding in patients treated with anticoagulants. Methods: The data of patients who underwent EST at 15 hospitals between July 2015 and June 2017 were extracted. We investigated the incidence of post‐EST bleeding and risk factors for bleeding in patients treated with anticoagulants. Results: One hundred forty‐nine patients undergoing EST who met the inclusion criteria were included in this study. The total‐EST bleeding (bleeding occurring during or after EST) rate did not differ between the heparin replacement (8.0%, 6/75) and continuation (16.6%, 2/12; P = 0.37) groups of warfarin users. The total‐EST‐bleeding rate in the heparin replacement group (12.9%, 4/31) was significantly higher than that in the continuation group (0%, 0/31; P = 0.016) in direct oral anticoagulant (DOAC) users. The rate of total‐EST bleeding with continuation of DOAC (0%, 0/31) was significantly lower with continuation of warfarin (16.6%, 2/12; P = 0.021). During‐EST bleeding (bleeding occurring during EST) (P = 0.0083) and precut (P = 0.033) were significant risk factors for post‐EST bleeding in all 149 patients. Heparin replacement was only a significant risk factor for total‐EST bleeding (P = 0.033) in DOAC users. Conclusion: Heparin replacement was a significant risk factor for post‐EST bleeding in DOAC users; however, there was no significant difference between the bleeding rate of heparin replacement and that of continuation groups in patients taking warfarin. During EST and precut were significant risk factors for post‐EST bleeding in all patients treated with anticoagulants. [ABSTRACT FROM AUTHOR]

We investigated the relationship between body mass index (BMI) and postoperative outcomes in 450 gallbladder cancer patients in Japan. We collected patient information, including sex, age, underlying disease, BMI, stage, surgery method, postoperative time to discharge, and postoperative Medicare fees, from the Japanese administrative database associated with the Diagnosis Procedure Combination system. We classified patient BMIs as underweight (BMI<18.5 kg/m2), normal (BMI≥18.5 kg/m2 and <25 kg/m2) or overweight/obese (BMI≥25 kg/m2), then investigated the relationship between these categories and two postoperative outcomes: time to discharge and postoperative Medicare fees. The median postoperative time to discharge was 12 days in all patients, and 12 days in each of the three weight groups (p=0.62, n.s.). The median postoperative Medicare fees from surgery until discharge were (USD): all patients, $5,002; underweight, $5,875; normal weight, $4,797; and overweight/obese, $5,179 (p=0.146, n.s.). A multivariate analysis with adjustment for competing risk factors revealed that BMI was not associated with increased risk of longer postoperative time to discharge (normal weight: HR 1.17, p=0.29; overweight/obese: HR 1.17, p=0.37) or higher postoperative Medicare fees (OR 0.99, p=0.86, n.s.). Thus, high BMI was not found to be a factor for poor postoperative outcomes in Japanese patients with gallbladder cancer., Competing Interests: No potential conflict of interest relevant to this article was reported.

Aim: The aim of the study was to assess the implication of Zonulin, a mediator protein synthesized by intestine and the liver,in patients with chronic liver diseases., Materials and Methods: Twenty-six patients with chronic liver diseases due to hepatitis C virus (HCV) and hepatitis B virus (HBV) were enrolled in this study. Out of total 26 patients, 17 were diagnosed as chronic hepatitis (CH) and 9 were patients with liver cirrhosis (LC). Twenty-four of these patients were infected with hepatitis C virus (HCV) and the rest two by hepatitis B virus (HBV). The study was conducted at Saiseikai-Imabari Hospital, Imabari, Ehime, Japan. Serum levels of Zonulin along with different parameters of liver function test were measured in all patients and comparative analyses were accomplished., Results: The serum levels of Zonulin were significantly lower in CH patients compared to controls (p<0.001). Also, the levels of Zonulin were significantly lower in patients with LC compared to CH and normal controls (p<0.001). Further analysis revealed that serum Zonulin was significantly lower in patients with LC having ascites than those without ascites (p <0.05). There was a significant correlation of serum levels of Zonulin with platelet count, cholinesterase, and albumin in patients with chronic liver diseases., Discussion: Decreased levels of Zonulin may be related to impaired production of this mediator in the diseased liver. It will be tempting to assess the regulation of Zonulin in the liver, a production site of the mediator., Abbreviations: LC: Liver cirrhosis, CH: Chronic hepatitis, HCV: Hepatitis C virus, HBV: Hepatitis B virus, LGS: Leaky gut syndrome How to cite this article: Akao T, Morita A, Onji M, Miyake T, Watanabe R, Uehara T, Kawasaki K, Miyaike J, Oomoto M.
