Pancreatitis Risk in Primary Hyperparathyroidism: Relation to Mutations in the SPINK1 Trypsin Inhibitor (N34S) and the Cystic Fibrosis Gene

Abstract

Pancreatitis risk is approximately 10-fold elevated in pHPT, but pancreatitis occurs infrequently. This indicates an existing but minor impact of pHPT-related hypercalcemia. If pancreatitis occurs, it seems associated with genetic risk factors such as mutations in the SPINK1 and CFTR genes. In contrast, a combination of both hypercalcemia and genetic variants in SPINK1 or CFTR increases the risk to develop pancreatitis in patients with pHPT.
