Liraglutide changes postprandial responses of gut hormones involved in the regulation of gallbladder motility

Weight reduction and the risk of gallbladder and biliary disease: A systematic review and meta-analysis of randomized clinical trials

In this meta-analysis, we aim to evaluate the risk of gallbladder and biliary disease of weight management strategies and investigate the association between weight reduction and risk of gallbladder or biliary disease. Randomized controlled trials (RCTs) with a duration of at least 12 weeks that compare antiobesity medications (AOMs) with placebo or bariatric surgery with less intensive weight management strategy were concluded. Weight management strategy was associated with a significant increased risk of gallbladder or biliary disease (OR 1.361, 95% CI 1.147 to 1.614, P < 0.001, I2 = 3.5%), cholelithiasis, cholecystitis, and cholecystectomy compared with placebo or controls. The increased risk of gallbladder or biliary disease was observed both in pharmacotherapies subgroup and bariatric surgery subgroup. With regards of specific pharmacotherapies, an increased risk of gallbladder or biliary disease was observed in trials with glucagon-like peptide 1 receptor agonist (GLP-1 RA) treatments. In addition, trials with indication of obesity and overweight treatment and trials with higher doses showed significant higher risk of gallbladder or biliary disease compared with placebo or controls. In conclusion, weight management strategy was associated with an increased risk of gallbladder or biliary disease when compared with placebo or control groups.

Teduglutide improves liver chemistries in short bowel syndrome-associated intestinal failure: Post hoc analysis

BACKGROUND

Chronic hepatic complications are common in patients with short bowel syndrome-associated intestinal failure (SBS-IF). Teduglutide, a glucagon-like peptide-2 analogue, demonstrated efficacy in reducing parenteral nutrition and/or intravenous fluid dependence among patients with SBS-IF in phase 3 clinical studies.

METHODS

This was a post hoc analysis of pooled data from two separate randomized, double-blind, placebo-controlled, multinational phase 3 clinical studies. Adult patients with SBS-IF with parenteral nutrition and/or intravenous fluid dependence without liver disease at baseline were randomized to treatment with the glucagon-like peptide-2 analogue teduglutide (0.05 or 0.10 mg/kg/day) or placebo subcutaneously once daily for 24 weeks. Mixed-effects models assessed the baseline predictors of change in liver chemistries.

RESULTS

Between baseline and week 24, teduglutide treatment (n = 109) was associated with least squares mean reductions in aspartate aminotransferase (-7.51 IU/L; P = 0.014), alanine aminotransferase (-12.15 IU/L; P = 0.002), and bilirubin (-5.03 µmol/L [-0.057 mg/dl]; P < 0.001) compared with that of the placebo (n = 59). These values were independent of reductions in parenteral nutrition and/or intravenous fluid dependence.

CONCLUSION

Teduglutide treatment was associated with reductions in liver chemistries by week 24, which is beneficial for patients with SBS-IF beyond improvements in parenteral nutrition and/or intravenous fluid dependence. Future studies should examine how long-term teduglutide might mitigate the risk of liver disease in patients with SBS-IF.

How traditional Chinese medicine can prevent recurrence of common bile duct stones after endoscopic retrograde cholangiopancreatography?

Common bile duct stones, as a type of cholelithiasis, are a benign biliary obstruction that easily acute abdominalgia, and Endoscopic Retrograde Cholangiopancreatography (ERCP) is usually the first choice for clinical treatment. However, the increasing recurrence rate of patients after treatment is troubling clinicians and patients. For the prevention of recurrence after ERCP, there is no guideline to provide a clear drug regimen, traditional Chinese medicine however has achieved some result in the treatment of liver-related diseases based on the "gut-liver-bile acid axis". On the basis of this, this article discusses the possibility of traditional Chinese medicine to prevent common bile duct stones (CBDS) after ERCP, and we expect that this article will provide new ideas for the prevention of recurrence of CBDS and for the treatment of cholelithiasis-related diseases with traditional Chinese medicine in future clinical and scientific research.

What is the evidence regarding the safety of new obesity pharmacotherapies

The use of gut-hormone receptors agonists as new therapeutic options for obesity and some of its related comorbidities, such as type 2 diabetes, has resulted in an unprecedented efficacy in the medical management of people living with obesity (PLWO). Appraisal of the safety of these drugs is of utmost importance considering the large number of PLWO, and the potentially long exposure to these pharmacotherapies. In this narrative review we summarize the evidence on the safety of liraglutide, semaglutide, and tirzepatide as derived from randomized clinical trials conducted in adults living with obesity. Additionally, the safety of these drugs is put into perspective with that of other drugs currently approved for the treatment of PLWO. Overall, the available data support a favorable efficacy versus safety balance for gut-hormone hormone receptor analogues in the treatment of these subjects. Nonetheless, it should be acknowledged that in the context of a chronic disease that has reached epidemic proportions, data from randomized clinical trials aimed primarily at proving the efficacy of these drugs may have been insufficient to unveil all the safety issues. Thus, continuous surveillance on the adverse effects of liraglutide, semaglutide, and tirzepatide is required as we use these drugs in a broader population than that represented in currently available clinical trials.
