Background:
Ketoacidosis in pregnant women with previously undiagnosed diabetes is rare. Although insulin-dependent diabetes has recently been classified as either autoimmune (type 1A) or nonimmune (type 1B; "chronic" and "fulminant" subtypes), the clinical characteristics of diabetes in such settings are not fully understood.
Case:
We report two pregnant patients with previously undiagnosed diabetes. They presented with severe diabetic ketoacidosis characterized by an abrupt onset, normal, or slightly elevated level of glycosylated hemoglobin, absence of diabetes-related autoimmune antibodies, and features typical of the "fulminant" subtype of nonimmune diabetes. The fetuses died in utero, and the mothers became insulin dependent.
Conclusion:
The "fulminant" subtype of diabetes may be associated with fetal death.
