RF28 | PSUN182 Risk of Pancreatitis After Glp-1 Receptor Agonist in Individuals With Known History of Pancreatitis

Abstract

Abstract Introduction Randomized clinical trials identified a small increased risk of acute pancreatitis in patients using glucagon-like peptide-1 receptor agonist (GLP1- RA) therapy. As a result, GLP-1RA therapy is generally avoided in patients with a history of acute pancreatitis. The aim of this report was to evaluate the real-world experience of GLP-1RA therapy in patients with a history of acute pancreatitis. Methods A retrospective chart review was conducted (2010-2019) using the enterprise-wide electronic health record (EHR) system. Patients with a history of acute pancreatitis and a subsequent encounter diagnosis of acute pancreatitis (ICD-9/ ICD-10 codes), after exposure to GLP-1R, were identified. Exposure to GLP-1RA was defined as a documented prescription for GLP-1RA in the EHR. Patients were followed until the date of recurrent acute pancreatitis (RAP) or censoring. Categorical and continuous variables were summarized using N (%) and mean (SD), respectively. Results A total of 161 patients were identified, 50.9% were female, 56.6% Caucasian, with mean age (years) 54 (±13) and mean BMI 35 kg/m2 (±8). Type 2 diabetes, hypertension, and obesity were present in 92.5% (N=149), 86.3% (N=139), and 73.9% (N=119), respectively. The mean duration of follow-up for all patients was 28.2 months (±24.6). The etiologies of the first documented episode of pancreatitis prior to GLP-1RA exposure were gall stones (N=49, 30.4%), alcoholism (N=21, 13%), hypertriglyceridemia (N=9, 5.6%), medication-induced N=5 (3.1%), and the remaining cases (N=77, 47.8%) were classified as idiopathic. Among these 161 patients, N=16 (9.9%) had a second episode of pancreatitis after GLP1-RA exposure. The mean duration of exposure to GLP-1RA prior to RAP was 10.8 months (±7.2). RAP was attributed to GLP 1-RA exposure N=6 (37.5%), alcohol intake N=2 (12.5%), hypertriglyceridemia N=3 (18.8%), oral hypoglycemic agent N=1 (6.2%), ampulla stenosis N=1 (6.2%), and the remaining N=3 (18.8%) were considered idiopathic. Conclusions Among 161 patients with a history of acute pancreatitis exposed to GLP-1RA, a total of 16 (9.9%) cases of RAP were identified, but only N=6 (4%) of these were determined attributable to GLP-1RA exposure. The overall rate of RAP among our cohort of GLP-1RA exposed patients (9.9%) is similar to the overall rate of RAP reported in the literature (12.7%), regardless of the underlying etiology or drug exposure.1 Acute pancreatitis related to drug exposure is a diagnosis of exclusion; thus, it is certainly possible that some of the cases in our report considered idiopathic were actually related to GLP-1RA exposure. While caution needs to be exercised, our data would support the use of GLP-1RA in patients with a history of acute pancreatitis, on an individualized basis, where the benefits are considered to outweigh the risks.
