    Abstract:
    OBJECTIVE: To describe lipid and lipoprotein perturbations in gestational diabetes mellitus (GDM) and to examine the potential consequences--e.g, increased birth weight and increased placental lipid transfer. STUDY DESIGN: Maternal and cord free fatty acids (FFAs) and total, very low density lipoprotein (VLDL), low density lipoprotein (LDL), high density lipoprotein (HDL) (and maternal HDL2 and HDL3), triglyceride (TG), and cholesterol and dietary intake were determined for women with diet-treated GDM and for healthy pregnant women with normal glucose tolerance. RESULTS: Women with GDM had higher hemoglobin A1c than controls, while body weight gain was significantly lower for women with GDM as compared to controls. Plasma and lipoprotein TG concentrations were greater for women with GDM, and although plasma FFAs were higher in women with GDM versus controls, the difference was not significant. No differences were observed between groups with respect to maternal plasma or lipoprotein cholesterol. Cord plasma and lipoprotein lipids were similar between groups; with the exception of VLDL + LDL TG, which was lower in women with GDM. In controls, there were significant correlations between maternal plasma TG and cord FFAs; maternal HDL2 cholesterol and cord plasma cholesterol; and maternal plasma TG, maternal HDL2 cholesterol, cord FFAs, and infant birth weight. In GDM, maternal plasma cholesterol and cord VLDL + LDL cholesterol correlated. There were no significant correlations between maternal or cord lipids and infant birth weight in women with GDM. CONCLUSION: Hypertriglyceridemia, rather than hypercholesterolemia, is a feature of GDM. However, elevations in maternal plasma and lipoprotein TGs in women with GDM were not related to fetal lipid concentrations or infant birth weight.
