Oxidative Stress in Women with Polycystic Ovary Syndrome

OBJECTIVE: To determine if oxidative stress and endothelial dysfunction exist at the same time in a young, non-obese group of patients with polycystic ovary syndrome (PCOS).
DESIGN: Cross-sectional study.
SAMPLE: Thirty-one young, non-obese patients with PCOS and 23 age- and body mass index-matched controls.
METHODS: Following clinical and biochemical diagnosis, malonyldialdehyde (MDA), superoxide dismutase (SOD), von Willebrand Factor (vWF), and nitric oxide (NO) levels of patients and controls were measured and compared.
MAIN OUTCOME MEASURES: To find out oxidative stress and endothelial dysfunction parameters.
RESULTS: MDA ...view middle of the document...

After being measured, the patients with PCOS (PCOS group 1) took VE 0.1 qd x 3 months, VC 0.2 bid x 3 months and Diane-35 (Ethinylestradiol and Cyproterone Acetate Tablets) 1 # qd x 21 d/month x 3 months. The LPO, MDA, SOD, VE and VC were measured after three months. The other 30 patients with PCOS (PCOS group 2) were chosen to take Diane-35 (Ethinylestradiol and Cyproterone Acetate Tablets) 1 qd x 21 d/month x 3 months only. The menstrual cycles were viewed in PCOS group 1 and PCOS group 2 for three months

METHODS: Following clinical and biochemical diagnosis, malonyldialdehyde (MDA), superoxide dismutase (SOD), von Willebrand Factor (vWF), and nitric oxide (NO) levels of patients and controls were measured and compared.
MAIN OUTCOME MEASURES: To find out oxidative stress and endothelial dysfunction parameters.
RESULTS: MDA (0.12+/-0.03 vs 0.10+/-0.03, p=0.01) and SOD (8.0+/-0.7 vs 7.28+/-0.8, p=0.001) levels were significantly higher in PCOS group while there was no difference in vWF (527.2+/-280.1 vs 568.1+/-276.8, p>0.05) and NO levels (169.9+/-47.4 vs 168.9+/-80, p>0.05). When the results of the PCOS patients were divided into two subgroups in terms of insulin resistance (IR- and IR + ), the IR- subgroup had significantly higher MDA levels compared to the control (0.125+/-0.03 vs 0.101+/-0.03, p=0.03). Though IR+ group also had higher MDA than the control group, it did not reach to a significant level (0.117+/-0.05 vs 0.101+/-0.03, p>0.05). Both IR- and...
