Background: Pancreatic safety remains a concern for diabetic patients using incretin-based medications. We aimed to determine if there was an association between incretin-based therapy and an increased risk for acute pancreatitis and pancreatic cancer in patients with type 2 diabetes mellitus (DM).

Methods: This retrospective population-based cohort study analyzed data from the Taiwan National Health Insurance Research Database. A total of 13 171 eligible type 2 DM patients who had received incretin-based treatment for a minimum of two months were matched 1:1 for age, gender, diabetes complications severity index, and inception date with DM patients who never used this pharmacotherapy. The cohorts were compared for occurrence of acute pancreatitis and pancreatic cancer. The association between incretin-based therapy and acute pancreatitis was assessed using a Cox proportional hazard model and stratified analyses.

Results: Acute pancreatitis occurred in 71 (0.54%) incretin users and 66 (0.50%) non-users, respectively (P = 0.67). The association remained insignificant (adjusted hazard ratio [HR], 1.06; 95% confidence interval [CI] = 0.72-1.55) after adjustment for cholelithiasis (adjusted HR, 2.76; 95% CI = 1.32-5.75) and alcohol-related disease (adjusted HR 9.14, 95% CI = 2.08-40.14) in the Cox model. Stratified analyses affirmed no association between incretin-based therapy and pancreatitis in any subgroup. Pancreatic cancer occurred in 6 (0.05%) and 10 (0.08%) patients in the user and non-user cohort, respectively (P = 0.32).

Conclusion: Incretin-based therapy is not associated with acute pancreatitis and short-term pancreatic cancer risk among ethnic Chinese patients with diabetes. This study supports the pancreatic safety of incretin-based pharmacotherapy.
