A 24-year-old woman admitted with fever and abdominal pain was found in laboratory tests to have elevated pancreatic enzyme.Abdominal ultrasonography and computed tomography showed diffuse pancreatic swelling.These findings indicated a diagnosis of acute pancreatitis.She was treated with gabexate mesilate and ulinastatin, and pancreatitis improved within a week.
On admission, urine sugar was negative, blood glucose 128mg/d
l, and HbA
1c4.5%, but blood glucose gradually elevated, developing into diabetes mellitus. Islet cell antibody and autoantibody to glutamic acid decarboxylase were negative. Virus antibody titers for mumps, rubella, Epstein-Barr virus, Coxsackie virus, and cytomegalovirus were also negative. Her insulin secretion severely impaired in the urinary C-peptide excretion and glucagon loading tests. This data suggested that her islet beta cells had been severely damaged by acute pancreatitis. The clinical course was interesting in that it was very similar to that of non autoimmune fulminant type 1 diabetes.
