title: Decreased total antioxidant status and increased oxidative stress in women with polycystic ovary syndrome may contribute to the risk of cardiovascular disease.
abstract: OBJECTIVE
  To determine oxidative stress by the level of protein carbonyls and total antioxidant status (TAOS), and whether oxidative stress is associated with increased risk of cardiovascular disease in women with polycystic ovary syndrome (PCOS).
  
  
  METHODS
  Controlled clinical study.
  
  
  METHODS
  University hospital.
  
  
  METHODS
  Thirty women with PCOS and 31 healthy control women.
  
  
  METHODS
  Biometric measures and blood samples collection.
  
  
  METHODS
  C-reactive protein (CRP), lipid fractions, glucose, protein carbonyls, insulin, and other hormone (gonadotropins, androgens) levels and TAOS were measured. The estimate of insulin resistance was calculated by homeostasis model assessment (HOMA-R).
  
  
  RESULTS
  The women with PCOS had significantly higher serum fasting insulin, CRP, protein carbonyl levels, HOMA-R, LH levels, and LH/FSH ratios than healthy women. However, TAOS was significantly lower in women with PCOS. TAOS was negatively correlated with fasting insulin, HOMA-R, CRP, and protein carbonyls. Fasting insulin was positively correlated with protein carbonyls. High density lipoprotein (HDL) was inversely associated with fasting insulin, HOMA-R, and protein carbonyls.
  
  
  CONCLUSIONS
  Increased oxidative stress and decreased antioxidant capacity may contribute to the increased risk of cardiovascular disease in women with PCOS, in addition to known risk factors such as insulin resistance, hypertension, central obesity, and dyslipidemia.
