ABSTRACT
Fulminant type 1 diabetes mellitus (FT1DM) is a clinical entity in which the process of beta-cell destruction and subsequent progression of hyperglycemia and ketoacidosis are extremely rapid. A 34-year-old woman without any known risk factor for diabetes mellitus experienced a sudden stillbirth at 30 weeks of gestation. She had normal oral glucose tolerance test during pregnancy. Her blood glucose level was 974 mg/dL. Her urine test for ketone bodies was positive. Her hemoglobin A1c level (6.8%) was near normal range at the first emergency room visit. These findings suggested a very recent onset of diabetes mellitus. Her serum C-peptide level was very low. Islet-related autoantibodies were undetectable. Her clinical course, biochemical, and immunological profiles were consistent with FT1DM. After fluid and insulin based management, beta-cell was rescued with insulin therapy during the evolution of FT1D. At 10 days after admission, maintenance dose of insulin was just 8 unit of insulin once daily. This is the first case of FT1DM with robust recovery in insulin secretion in a pregnant woman who had an initial manifestation of 3rd-trimester intrauterine fetal death in Korea.
