title: The levels of leptin, adiponectin, and resistin in normal weight, overweight, and obese pregnant women with and without preeclampsia.
abstract: OBJECTIVE
  The purpose of this study was to compare adipokines' levels between women with and without preeclampsia based on maternal body mass index (BMI).
  
  
  METHODS
  This was a cross-sectional study among third-trimester pregnancies with preeclampsia (PIH) compared with normotensive controls. Serum levels of adiponectin, leptin, and resistin were measured before delivery by radioimmunoassay or enzyme-linked immunosorbent assay (ELISA).
  
  
  RESULTS
  The study included 22 normotensive and 77 PIH women. Leptin levels increased with maternal BMI. In patients with severe preeclampsia, overweight, and obese women had increased leptin levels (33.4 +/- 14.8 vs 23.0 +/- 10.8 ng/mL respectively, P = .02), and decreased adiponectin levels (8.4 +/- 5.3 vs 12.6 +/- 6.0 ng/mL, P = .03) compared with normal weight women. In women with BMI <25 kg/m2, adiponectin levels increased in patients with preeclampsia compared with controls (11.5 +/- 5.6 vs 9.6 +/- 4.6 and 7.0 +/- 3.2 ng/mL, respectively, P = .005). There was no association between resistin levels and preeclampsia or maternal BMI.
  
  
  CONCLUSIONS
  Women with severe preeclampsia and BMI > or = 25 kg/m2 have decreased adiponectin and increased leptin levels, while normal weight women with preeclampsia have increased adiponectin levels.
