Screening for variants in TPMT did not reduce the proportions of patients with hematologic ADRs during thiopurine treatment for IBD. However, there was a 10-fold reduction in hematologic ADRs among variant carriers who were identified and received a dose reduction, compared with variant carriers who did not, without differences in treatment efficacy.

Gastroesophageal variceal bleeding in patients with cirrhosis is associated with significant morbidity and mortality, as well as a high rebleeding risk. Limited data are available on the role of transjugular intrahepatic portosystemic shunt (TIPS) with covered stents in patients receiving standard endoscopic, vasoactive, and antibiotic treatment. In this multicenter randomized trial, long-term endoscopic variceal ligation (EVL) or glue injection 1 b-blocker treatment was compared with TIPS placement in 72 patients with a first or second episode of gastric and/or esophageal variceal bleeding, after hemodynamic stabilization upon endoscopic, vasoactive, and antibiotic treatment. Randomization was stratified according to Child-Pugh score. Kaplan-Meier (event-free) survival estimates were used for the endpoints rebleeding, death, treatment failure, and hepatic encephalopathy. During a median follow-up of 23 months, 10 (29%) of 35 patients in the endoscopy 1 b-blocker group, as compared to 0 of 37 (0%) patients in the TIPS group, developed variceal rebleeding (P 5 0.001). Mortality (TIPS 32% vs. endoscopy 26%; P 5 0.418) and treatment failure (TIPS 38% vs. endoscopy 34%; P 5 0.685) did not differ between groups. Early hepatic encephalopathy (within 1 year) was significantly more frequent in the TIPS group (35% vs. 14%; P 5 0.035), but during longterm follow-up this difference diminished (38% vs. 23%; P 5 0.121). Conclusions: In unselected patients with cirrhosis, who underwent successful endoscopic hemostasis for variceal bleeding, covered TIPS was superior to EVL 1 b-blocker for reduction of variceal rebleeding, but did not improve survival. TIPS was associated with higher rates of early hepatic encephalopathy. (HEPATOLOGY 2016;63:581-589) G astroesophageal variceal bleeding (GEVB) is a severe complication of portal hypertension. Rebleeding is associated with significant morbidity and mortality. Hospitalization costs for rebleeding range between $6,600 and $23,000 in the United States.For these reasons, management should be directed at its prevention.1,2 Secondary prevention is first achieved by endoscopic treatment (endoscopic variceal ligation [EVL] for esophageal varices and N-butyl cyanoacrylate injection for gastric varices) in combination with bAbbreviations: CI, confidence interval; EVL, endoscopic variceal ligation; GEVB, gastroesophageal variceal bleeding; HCC, hepatocellular carcinoma; HR, hazard ratio; IQR, interquartile range; MELD, Model for End-Stage Liver Disease; PTFE, polytetrafluorethylene; TIPS, transjugular intrahepatic portosystemic shunt.From the Departments of

Although placement of SEMS (uncovered or partially covered) for palliation of extrahepatic bile duct obstruction initially is more expensive than placement of plastic stents, SEMS have longer functional time. The total costs after 1 year do not differ significantly with stent type. Dutch Clinical Trial Registration no: NTR1361.

BackgroundData on clinical characteristics of patients with inflammatory bowel disease (IBD)-related colorectal cancer (CRC) are scarce and mainly originate from tertiary referral centres. We studied patient and disease characteristics of IBD-related CRC in a nationwide IBD cohort in general hospitals. Main outcome parameters were time to develop CRC, and factors associated with early CRC development.MethodsAll IBD patients diagnosed with CRC between 1 January 1990 and 1 July 2006 were identified using a nationwide automated pathology database (PALGA). Patient charts were assessed to confirm diagnosis and collect clinical data. Early CRC was defined as CRC diagnosed less than 8 years after IBD diagnosis. Statistical analysis was performed using descriptive statistics, independent t tests, binary logistic regression and Cox-regression analysis.ResultsDiagnosis of IBD-related CRC was confirmed in 251 patients (171 ulcerative colitis, 77 Crohn’s disease, 3 unclassified colitis), 161 males (64 %). Median time from IBD diagnosis to CRC diagnosis was 12 years (IQR 4–20); 89 patients (35 %) developed early CRC. Type of IBD, gender, concomitant PSC, pseudopolyps, extent of inflammation, and medication use were not related to early CRC (p > 0.05). IBD diagnosis at older age (HR for 10 years older age 2.25; 95 % CI 1.92–2.63) was related to early CRC. Twenty-three patients (12 %) had been included in a surveillance programme prior to CRC diagnosis. Patients in the surveillance group had a significantly better tumor stage (p = 0.004).ConclusionsWe emphasize the problem of a high proportion of IBD-associated CRCs developing before the recommended start of surveillance. Therefore, we suggest that older age at IBD onset could be an additional factor to start surveillance in IBD patients.

The substituted benzimidazole derivatives omeprazole and lansoprazole selectively inhibit the proton pump (H + , K + -ATPase) of the gastric parietal cell, the ®nal step of gastric acid secretion. Methods: A randomized, investigator-blind, crossover study design was used. Intragastric pH was measured continuously with glass electrodes positioned in the gastric corpus. Sixteen H. pylori-negative subjects, whose intragastric acidity fell below pH 4 for 70% of a 24-h baseline period, were entered in the study.
