Hereditary pancreatitis in a young adult: Acute to chronic.

This report investigates an unusual case of recurrent pancreatitis. A 22-year-old female was admitted to the emergency room for severe abdominal pain, nausea, and weight loss. She reported having these symptoms since she was a toddler. The clinician ordered fecal pancreatic elastase-1, fat-soluble vitamins, molecular studies, and imaging of the pancreas by computed tomography. The screening test result for fecal pancreatic elastase-1 revealed severe pancreatic exocrine insufficiency, and the concentrations of fat-soluble vitamins were also low. Imaging showed scattered calcifications in the pancreas. These findings supported a diagnosis of chronic pancreatitis. Due to the rarity of chronic pancreatitis in young adults, molecular studies were performed. The patient was found to be homozygous for a mutation in the SPINK1 gene, which is associated with hereditary pancreatitis. This case report discusses hereditary pancreatitis and highlights data on the utilization of fecal pancreatic elastase-1 to assess pancreatic exocrine insufficiency.
