OBJECTIVES: Patients with inflammatory bowel diseases are suggested to have an increased risk of acute pancreatitis. Although azathioprine and glucocorticoids are risk factors for acute pancreatitis, the relation is poorly understood, in particular the role of 5-aminosalicylic acid and sulfasalazine treatment. To clarify these relations, we conducted a population-based case-control study. METHODS: We identified 1,590 incident cases of acute pancreatitis from the Hospital Discharge Registry of the North Jutland County of Denmark from 1991 to 2002, and selected 10 controls per case (N = 15,913) from the Central Personal Registry, matched by age and gender. Among cases and controls, we identified patients with inflammatory bowel diseases. Data on drug use were extracted from a Pharmaco-epidemiological Prescription Database. RESULTS: Adjusted odds ratios for acute pancreatitis in patients with Crohn's disease and ulcerative colitis were 3.7 (95% confidence interval (CI), 1.9-7.6) and 1.5 (95% CI, 0.7-3.6), respectively. In all patients treated with 5-aminosalicylic acid and sulfasalazine the adjusted odds ratios for acute pancreatitis were 0.7 (95% CI, 0.4-2.2) and 1.5 (95% CI, 0.4-5.2), respectively. Restricted to patients with inflammatory bowel diseases only, the adjusted odds ratios for acute pancreatitis in patients exposed to 5-aminosalicylic acid and sulfasalazine were 0.7 (95% CI, 0.1-3.8) and 0.6 (95% CI, 0.1-6.7), respectively. CONCLUSION: We found a nearly four-fold increased risk of acute pancreatitis in patients with Crohn's disease and a 1.5-fold increased risk for ulcerative colitis. In patients with inflammatory bowel diseases, the use of 5-aminosalicylic acid or sulfasalazine was not associated with increased risk of acute pancreatitis.
