Bortezomib-induced acute pancreatitis, an uncommon adverse event.

Acute pancreatitis is one of the main reasons for hospitalization, with an increasing incidence and associated non-negligible morbidity and mortality. Its most common causes are alcohol and gallstones, and medications are a rare cause. The pathogenesis of acute drug pancreatitis is not yet known exactly and the diagnosis is based on the evident temporal relationship, having excluded the rest of the possible known causes of acute pancreatitis. We present the case of a 71-year-old patient diagnosed with IgG multiple myeloma treated with the Daratumumab, Bortezomib and Dexamethasone regimen. After Bortezomib administration, he developed epigastric pain and elevated pancreatic enzymes in the range of acute pancreatitis. After ruling out common causes, the diagnosis of acute pancreatitis caused by Bortezomib was reached, which presents a favorable rapid evolution after its elimination.
