Results. The esophageal epithelium from GERD patients had lower electrical resistance and higher epithelial currents than controls. Claudin-1 and -4 were significantly decreased in GERD patients. The bile salt DCA in the low concentration of 1.5 mM and trypsin increased the resistance and claudin-1 expression, while the higher concentration of 2.5 mM DCA and trypsin decreased the resistance and the claudin-3, -4 and E-cadherin expressions. Conclusion. In addition to acidic reflux, duodenal reflux components, such as bile salts and trypsin, have the potential to disrupt the

esophageal barrier function, partly by modulating the TJ proteins. However, the expression of TJ is dependent on both the refluxed material as well as the concentration of the bile salt.”
“Objective. selleck screening library Meta-analyses have indicated effect of probiotics on irritable bowel syndrome (IBS). However, few long-term trials have been conducted and

uncertainty remains as to effectiveness and long-term effect in a primary care setting. We aimed to investigate the effect of probiotics compared with placebo in the management of IBS in primary care during a 6-month treatment period and AR-13324 with a 6-month follow-up. Material and methods. We randomized IBS patients fulfilling Rome III criteria to receive two capsules twice daily either containing placebo or a probiotic mixture of Lactobacillus paracasei ssp paracasei F19, Lactobacillus acidophilus L alpha 5 and Bifidobacterium Bb12 in

an amount of 1.3 x 10(10) CFU per capsule. Primary endpoint was proportion of responders defined as patients reporting adequate relief (AR) at least 50% of the time in the 6-month treatment period. Secondary outcomes were proportions of patients reporting AR at different time points, and change in gastrointestinal symptoms and health-related quality of life (HrQOL) from baseline to 6 and 12 months. 3-oxoacyl-(acyl-carrier-protein) reductase Results. A total of 131 patients were included in this study. The proportion of responders in the treatment period was 52% (35/67) in the probiotic group versus 41% (26/64) in the placebo group, p = 0.18. Overall we found no difference between the groups in change in gastrointestinal symptoms after treatment. Patients improved in HrQOL, but with no statistically significant difference between the groups. Conclusion. During a 6-month treatment period, we were not able to detect a positive effect of probiotic when compared with placebo.”
“Objective. The intestinal microbiota plays a substantial role in the pathogenesis of inflammatory bowel disease (IBD). Faecalibacterium prausnitzii (FP) is underrepresented in IBD patients and have been suggested to have anti-inflammatory effects in mice.
