Background: Polycystic ovary syndrome (PCOS) is a cardiornetabolic disorder whose features include dyslipidemia, increased oxidative stress (OS, oxy) and chronic inflammation. The aim of this study was to investigate the ability of a summary score for dyslipidemia, OS and inflammation (the DOI score) to discriminate PCOS patients from healthy individuals and to evaluate the effect of obesity on individual scores and the DOI score in patients. Methods: Lipid status parameters, OS status parameters (advanced oxidation protein products; total oxidative status; prooxidant-antioxidant balance; malondialdehyde; total protein sulphydryl groups and paraoxonase 1 activity) and CRP were measured in 114 patients and 50 controls using standardised assays. The DOI score was calculated as the sum of dyslipidemia, oxy and inflammation scores, determined as Z-score values for every subject in relation to the controls. Results: PCOS patients had significantly higher oxy-score compared to controls (P lt... 0.001). In addition, the DOI score was significantly higher in PCOS patients (P lt 0.001) as the dyslipidemia (P lt 0.05) and inflammatory scores (P lt 0.001) were greater. According to ROC analysis, the oxy-score showed better diagnostic accuracy in discriminating PCOS patients compared to the DOI score (AUC>0.9, P lt 0.01). Furthermore, obesity affected the risk scores in patients, especially the DOI score (significantly higher DOI scores in such patients, P lt 0.001). Conclusion: PCOS patients had greater dyslipidemia, chronic inflammation and OS compared to controls and could be segregated using all four scores. Our data suggest that weight gain could be the common factor responsible for induction and propagation of dyslipidemia, OS and inflammation in PCOS patients.
