OBJECTIVE: Preeclampsia (PE) is a serious complication of pregnancy, the pathogenesis of which is largely unknown. We hypothesize that adipocytokines may play a role in the pathogenesis of PE, particularly in obese women, and evaluate leptin and adiponectin as potential first trimester markers for predicting PE.

STUDY DESIGN: A cohort of 2503 pregnancies, containing 93 PE pregnancies, was divided into women with normal weight, moderate, or severe obesity. All pregnancies had serum adiponectin and leptin measured in first trimester. Logistic regression was used to model PE with maternal characteristics and concentrations of the biomarkers.

RESULTS: In obese women a lower concentration of adiponectin was found in PE pregnancies; the concentration was lowest in the severely obese (p?=?0.005). No association was found in normal weight women (p?=?0.72). Leptin concentration had no association with PE in normal weight and moderately obese (p?=?0.175-0.072), however in women with severe obesity a lower level of leptin was found (p?=?0.049). The AUC was 0.73 for the ROC curve of combined maternal characteristics and adiponectin. Using adiponectin in women with moderate to severe obesity the sensitivity was 72.9% and the specificity was 49%.

CONCLUSIONS: In severely obese women, PE is associated with low serum adiponectin and leptin concentrations in first trimester. This indicates that the inability of adipokine regulation to adapt to severe obesity may play a role in the pathogenesis of PE. Adipocytokines may contribute in identification of risk pregnancies among severe obese.
