title: Decreased paraoxonase and arylesterase activities in the pathogenesis of future atherosclerotic heart disease in women with gestational diabetes mellitus.
abstract: OBJECTIVE
  The aim of this study was to investigate serum paraoxonase, arlyesterase activities, and lipid hydroperoxide (LOOH) levels in patients with gestational diabetes mellitus (GDM).
  
  
  METHODS
  Paraoxonase and arylesterase activities, and LOOH levels were assessed for GDM cases (n = 55) and controls (n = 59). Serum basal and salt-stimulated paraoxonase and arylesterase activities were measured spectrophotometrically. LOOH levels were measured by ferrous oxidation with a xylenol orange assay.
  
  
  RESULTS
  Basal and salt-stimulated paraoxonase and arylesterase activities were significantly lower (p = 0.002, p = 0.004; and p = 0.013, respectively) in patients with GDM compared to controls, while LOOH levels were significantly higher (p < 0.001). Among gestational diabetes patients, serum paraoxonase and arylesterase activities were inversely correlated with LOOH levels (r = - 0.390, p = 0.003; and r = - 0.287, p = 0.034, respectively).
  
  
  CONCLUSIONS
  Findings of the present study have shown that serum paraoxonase and arylesterase activities are significantly reduced in women with GDM. Decreased serum paraoxonase and arylesterase activities might play a role in the potential early pathogenesis for atherosclerotic heart disease in GDM beyond their antioxidant properties.
