Background: Hypercalcemia is a rare but well recognized cause of acute and chronic pancreatitis. Hypercalcemia-related pancreatitis is mainly caused by primary hyperparathyroidism. The prevalence of pancreatitis in hyperparathyroidism varies worldwide and additional disease-modifying factors may play a role in its development. In 1988 the prevalence of pancreatitis secondary to primary hyperparathyroidism at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (INCMNSZ), a referral center in Mexico City, was 12.1% (95% CI: 6.7-21). Objective: To describe the current prevalence of pancreatitis secondary to primary hyperparathyroidism at the INCMNSZ. Methods: We reviewed 385 cases of primary hyperparathyroidism seen at the hospital between 1987 and 2012. Results: 26 cases with acute or chronic pancreatitis associated with primary hyperparathyroidism were documented, with a prevalence of 6.7% (95% CI: 4.6-9.7), which was lower than the 12.1% previously reported. In the present study, 20% had a history of alcohol consumption, 10% of gallstones, and 20% of ureteral calculi, compared with the previously reported 32.0, 34.6, and 40.0%, respectively. The average calcium levels were 13.1 and 13.8 mg/dl in the previous and current series, respectively. Conclusions: We found a decrease in the prevalence of pancreatitis associated with primary hyperparathyroidism from 12.1% (95% CI: 6.7-21) to 6.7% (95% CI: 4.6-9.7).
