AIM: To assess the role of first trimester maternal testosterone and dehydroepiandrosterone sulfate (DHEA-S) levels in prediction of development of gestational diabetes mellitus (GDM).
METHODS: Four hundred and fifty pregnant women were included in this prospective cohort study. All pregnant women with a singleton pregnancy who were not diabetic, had no family history of diabetes, had no history of previous GDM, were of white race and non-smokers were enrolled. Total testosterone and DHEA-S were measured at 11-14 weeks of gestation. The patients were called for routine pregnancy visits and followed accordingly. Forty-two patients did not come to their visits and were excluded. During gestational weeks 24-28, the remaining 408 patients were screened for GDM. The total testosterone and DHEA-S levels were compared between patients with and without GDM. Regression and receiver-operator curve analysis were performed.
RESULTS: GDM developed in 22 women (5.7%). Compared with women without GDM, first trimester total testosterone levels were higher among women in whom GDM subsequently developed. The DHEA-S level did not differ. Age, total testosterone and body mass index were found to be independent predictors of GDM development. A total testosterone value of 0.45 ng/mL was found to predict development of GDM with a sensitivity of 63.6% and a specificity of 62.7%.
CONCLUSION: First trimester total testosterone has a low testing power for GDM screening with low sensitivity and specificity values and cannot be used as a marker alone. It may have a role in combination with other markers.
