Hypercalcemia- An enigmatic cause of acute pancreatitis

Abstract

Background: Acute pancreatitis (AP) continues to be one of the common abdominal emergencies encountered in tertiary care hospitals. The majority of AP is caused by gall stones and alcohol. Hypercalcemia though uncommon has been reported to cause AP, recurrent AP, and chronic pancreatitis (CP). Aim: The aim of this study was to describe hypercalcemia-induced AP in different settings. Materials and Methods: In total 100 patients with AP, admitted from January 2021 to December 2021 at our center, etiologies were biliary (36%), alcohol (19%), idiopathic (21%), alcohol plus Biliary (5%), post-endoscopic retrograde cholangiopancreaticography (7%), drug-induced (6%), hypercalcemia (3%), and dengue infection (3%). Overall mortality was 11%. Results: In three patients with hypercalcemia-induced pancreatitis, causes of hypercalcemia were multiple myeloma, parathyroid adenoma leading to hyperparathyroidism, and hypervitaminosis D in association with hyperthyroidism. Conclusion: Hypercalcemia-induced AP is not a rare phenomenon and should be actively investigated to prevent further attacks of AP and progression to CP. Relevance for Patients: Hypercalcemia is a potentially treatable cause of AP and its identification will not only help to treat and prevent further episodes of pancreatitis but also to manage underlying diseases leading to hypercalcemia.
