Evidence of high circulating testosterone in women with prior preeclampsia.

Women with prior preeclampsia are characterized by hyperinsulinemia and a 2- to 3-fold excess risk of hypertension and ischemic heart disease in later life. We therefore studied whether these women present changes in pituitary, ovarian, and endothelial factors that could also affect the risk of vascular disorders. Twenty-two women with prior preeclampsia and 22 control women matched by age and body mass index were studied an average of 17 yr after delivery. Women with prior preeclampsia had elevated serum free testosterone levels (20.6 +/- 2.2 vs. 15.0 +/- 1.3 pmol/L, mean +/- SE, P = 0.03), an elevated free androgen index (3.2 +/- 0.5 vs. 1.9 +/- 0.2, P = 0.04), and an elevated free testosterone estradiol ratio (0.089 +/- 0.017 vs. 0.046 +/- 0.006, P = 0.02). The levels of insulin-like growth factor binding protein-1 decreased as expected during a 3-h oral glucose tolerance test without differences between the groups. Levels of FSH, LH, androstenedione, dehydroepiandrosterone sulfate, and endothelin-1, as well as urinary output of prostacyclin and thromboxane A2 metabolites, showed no difference between study groups. A history of preeclampsia an average of 17 yr earlier thus appears to be associated with elevated levels of testosterone, which may contribute to the increased risk of vascular morbidity in such women.
