The association of primary hyperparathyroidism and pancreatitis

Abstract

The long-held tenet that a cause and effect relation exists between primary hyperparathyroidism and pancreatitis has recently been questioned. To clarify this association, records of 1475 patients seen with pancreatitis during a 10-year period were reviewed. Five patients (0.4%) were identified with primary hyperparathyroidism. The four men and one woman ranged in age from 31 to 57 years. Four had recurrent pancreatitis over a 2-10 yr period before hyperparathyroidism was diagnosed. One patient had hypercalcemia noted 1 year prior to developing pancreatitis. Four patients had associated potential causes of pancreatitis including alcohol abuse, gallstones, and hypotension. Pancreatitis was severe in each patient. Two patients had more than four admissions for acute pancreatitis, one patient underwent pseudocyst drainage and distal pancreatectomy for chronic pancreatitis, one patient underwent pancreaticojejunostomy for chronic pancreatitis, and one patient died from hemorrhagic pancreatitis. Four patients have undergone successful parathyroidectomy and have had no further attacks of pancreatitis on follow-up ranging from 1 to 4 years. Hyperparathyroidism is rarely associated with pancreatitis, but when this combination occurs, the pancreatitis is likely to be severe. Despite its rarity, a cause and effect relationship is still suggested by the fact that parathyroidectomy seems to prevent recurrence of pancreatitis.
