Total parenteral nutrition (TPN) is essential for patients with impaired gut function but leads to parenteral nutrition-associated liver disease (PNALD). TPN disrupts the normal enterohepatic circulation of bile acids, and we hypothesized that it would decrease intestinal expression of the newly described metabolic hormone fibroblast growth factor-19 (FGF19) and also glucagon-like peptides-1 and -2 (GLP-1 and GLP-2). We tested the effects of restoring bile acids by treating a neonatal piglet PNALD model with chenodeoxycholic acid (CDCA). Neonatal pigs received enteral feeding (EN), TPN, or TPN + CDCA for 14 days, and responses were assessed by serum markers, histology, and levels of key regulatory peptides. Cholestasis and steatosis were demonstrated in the TPN group relative to EN controls by elevated levels of serum total and direct bilirubin and also bile acids and liver triglyceride (TG) content. CDCA treatment improved direct bilirubin levels by almost fourfold compared with the TPN group and also normalized serum bile acids and liver TG. FGF19, GLP-1, and GLP-2 were decreased in plasma of the TPN group compared with the EN group but were all induced by CDCA treatment. Intestinal mucosal growth marked by weight and villus/crypt ratio was significantly reduced in the TPN group compared with the EN group, and CDCA treatment increased both parameters. These results suggest that decreased circulating FGF19 during TPN may contribute to PNALD. Moreover, we show that enteral CDCA not only resolves PNALD but acts as a potent intestinal trophic agent and secretagogue for GLP-2.

Our results show that cyanoacrylate is more effective and achieves GV obliteration faster than injection sclerotherapy with alcohol. It also appears to be more useful in controlling acute GV bleeding, with less of a need for rescue surgery.

Both types of breathing exercises benefit patients with hypertension. However, improvement in both the sympathetic and parasympathetic reactivity may be the mechanism that is associated in those practicing the slow-breathing exercise.

Globally, around 150 million people are infected with hepatitis C virus (HCV). India contributes a large proportion of this HCV burden. The prevalence of HCV infection in India is estimated at between 0.5% and 1.5%. It is higher in the northeastern part, tribal populations and Punjab, areas which may represent HCV hotspots, and is lower in western and eastern parts of the country. The predominant modes of HCV transmission in India are blood transfusion and unsafe therapeutic injections. There is a need for large field studies to better understand HCV epidemiology and identify high-prevalence areas, and to identify and spread awareness about the modes of transmission of this infection in an attempt to prevent disease transmission.

Background & Aims No treatment for nonalcoholic fatty liver disease (NAFLD) has been approved by regulatory agencies. We performed a randomized controlled trial to determine whether 52 weeks of cysteamine bitartrate delayed release (CBDR) reduces the severity of liver disease in children with NAFLD. Methods We performed a double-masked trial of 169 children with NAFLD Activity Scores ≥ 4 at 10 centers. From June 2012 to January 2014, the patients were randomly assigned to receive CBDR or placebo twice daily (300 mg for ≤65 kg, 375 mg for >65–80 kg, 450 mg for >80 kg) for 52 weeks. The primary outcome from the intention to treat analysis was improvement in liver histology over 52 weeks, defined as a decrease in NAFLD Activity Score ≥ 2 points without worsening fibrosis; patients without biopsies from week 52 (17 in the CBDR group and 6 in the placebo group) were considered non-responders. We calculated relative risks (RR) of improvement using stratified Cochran-Mantel-Haenszel analysis. Results There was no significant difference between groups in the primary outcome (28% of children in the CBDR group vs 22% in the placebo group; RR, 1.3; 95% CI, 0.8–2.1; P=.34). However, children receiving CBDR had significant changes in pre-specified secondary outcomes: reduced mean levels of alanine aminotransferase (reduction of 53±88 U/L vs a reduction of 8±77 U/L in the placebo group; P=.02) and aspartate aminotransferase (reduction of 31±52 vs a reduction of 4±36 U/L in the placebo group; P=.008), and a larger proportion had reduced lobular inflammation (in 36% of patients in the CBDR group vs placebo 21% of patients in the placebo group; RR, 1.8; 95% CI, 1.1–2.9; P=.03). In a post-hoc analyses, of children ≤65 kg, those taking CBDR had a 4-fold better chance of histologic improvement (observed in 50% of children in the CBDR group vs 13% in the placebo group; RR, 4.0; 95% CI, 1.3–12.3; P=.005). Conclusions In a randomized trial, we found that 1 year of CBDR did not reduce overall histologic markers of NAFLD compared with placebo in children. Children receiving CBDR did, however, have significant reductions in serum levels of aminotransferase levels and lobular inflammation. ClinicalTrials.gov no: NCT01529268.
