| Abstract BACKGROUND AND AIMS: Azathioprine (AZA) is recommended for maintenance of steroid-free remission in IBD. The aim of this study has been to establish the incidence and severity of AZA-induced pancreatitis, an idiosyncratic and major side effect, and to identify specific risk factors. METHODS: We studied 510 IBD patients (338 Crohn's disease, 157 ulcerative colitis, 15 indeterminate colitis) with initiation of AZA treatment in a prospective multicenter registry study. Acute pancreatitis was diagnosed in accordance with international guidelines. RESULTS: AZA was continued by 324 (63.5%) and stopped by 186 (36.5%) patients. The most common cause of discontinuation was nausea (12.2%). AZA-induced pancreatitis occurred in 37 patients (7.3%). Of these, 43% were hospitalized with a median inpatient time period of 5 days; 10% had peripancreatic fluid collections, 24% had to vomit and 14% had fever. No patient had to undergo nonsurgical or surgical interventions. Smoking was the strongest risk factor for AZA-induced acute pancreatitis (p<0.0002) in univariate and multivariate analyses CONCLUSIONS: AZA-induced acute pancreatitis is a common adverse event in IBD patients, but had a mild course in all patients. Smoking is the most important risk factor. |
