Aims:
Several randomized trials with metabolic outcomes have reported that glucagon like peptide-1 receptor agonists (GLP-1 RA) could be associated with an increased risk of pancreatitis. The present meta-analysis aimed to examine this hypothesis.
Methods:
An extensive Medline, Embase, and Cochrane Database search for "exenatide", "liraglutide", "albiglutide", "taspoglutide", "dulaglutide", "lixisenatide", and "semaglutide" was performed up to March 31st, 2013.
Inclusion Criteria:
(i) randomized trials, (ii) duration ≥12 weeks; (iii) on type 2 diabetes; and (iv) comparison of GLP-1RA with placebo or active drugs. Mantel-Haenszel odds ratio with 95% confidence interval (MH-OR) was calculated for pancreatitis.
Results:
80 eligible trials were identified. Of these, 39 had not disclosed their findings or did not report any information on pancreatitis. The remaining 41 trials enrolled 14,972 patients, with a total exposure of 14,333 patient × years (8353 and 5980 patient × years for GLP-1 receptor agonists and comparators, respectively). The overall risk of pancreatitis was not different between GLP-1RA and comparators (MH-OR: 1.01[0.37; 2.76]; p = 0.99).
Conclusions:
The present meta-analysis does not suggest any increase in the risk of pancreatitis with the use of GLP-1RA. However, it should be recognized that the number of observed cases of incident pancreatitis is very small and the confidence intervals of risk estimates are wide.

GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
