Abstract

Objectives

We present a case of immune-mediated diabetes mellitus, diagnosed in pregnancy upon presentation with diabetic ketoacidosis, found to have normal glucose control postpartum.

Case presentation

A 28-year-old medically uncomplicated G1P0 presented in diabetic ketoacidosis at 28.2 weeks gestation. Workup for pancreatic autoantibodies revealed indeterminate anti-islet cell antibodies and positive anti-glutamic acid antibodies. She was stabilized with intravenous fluids and insulin, and transitioned to long and short acting subcutaneous insulin. Her insulin requirements decreased over the course of her pregnancy. Spontaneous vaginal delivery occurred at 37 weeks. Her postpartum glucose control was normal without re-initiation of insulin.

Conclusions

The diagnosis of diabetic ketoacidosis during pregnancy should prompt further investigation into an underlying diagnosis of immune mediated diabetes. These patients should be followed closely in the postpartum period.
