title: Polycystic ovary disease. A risk factor for gestational diabetes?
abstract: We investigated the impact of pregestationally elevated insulin plasma levels on glycemic control in pregnant women with polycystic ovary disease (PCOD). Twelve patients with PCOD who became pregnant within six months following evaluation of their metabolic status were the study subjects. Four were obese and six (two obese) had a hyperinsulinemic response to the oral glucose tolerance test (OGTT). They were tested with the OGTT at 28-30 weeks of gestation. We also tested 12 normal patients and 10 consecutive patients with gestational diabetes; all were at the same gestational age. Plasma levels of insulin and glucose were determined in the samples collected for a period of four hours after glucose load (100 g). All PCOD patients significantly increased their insulin secretion in pregnancy. The hyperinsulinemic PCOD patients developed gestational diabetes (two patients) and impaired gestational glucose tolerance (three patients). The area under the insulin curve was greater in PCOD patients than in control and gestational diabetes patients (P < .01). In spite of their large increase in insulin secretion observed during pregnancy, patients with PCOD may develop a derangement of glycemic control, probably related to their pregestational insulinemic status.
