    Abstract:
    OBJECTIVE: To investigate putative dyslipidemia in women with polycystic ovary syndrome (PCOS) with particular emphasis on specific parameters of atherosclerotic risk, and to assess the independent influence of obesity and hyperandrogenemia on these parameters. SUBJECTS: Women investigated were among those attending the infertility clinics. Three groups of women were studied: (I) a core study group consisting of oligomenorrhoeic, chronically anovulatory women with or without obesity in whom polycystic ovaries were confirmed through ultrasound evidence, and were established to be the cause of infertility; II) a control group of non-hirsute, non-obese women with regular menstrual cycles; and (III) a group of controls consisting of women with obesity, but with normal ovarian morphology and regular menstrual cycles. METHODS: All three study groups were investigated for androgen (total testosterone) and lipid-lipoprotein profile, including apolipoproteins, ApoA1 and ApoB. Retrospective analysis of the data was carried out to assess hyperandrogenism in the study group of women with PCOS as well as to investigate changes in the lipid-lipoprotein profile, particularly the measures of cardiovascular risk, ApoA1 and ApoB. RESULTS: Triglycerides showed a significant increase in the PCOS group compared to controls, whereas HDL-cholesterol as well as HDL-carrying ApoA1 showed a significant decrease (P < .05). Also a significant finding was the decrease in ApoA1/ApoB ratio among the women with PCOS compared to both controls and obese women. A direct negative correlation of this decrease in ApoA1/ApoB ratio with the Body Mass Index was also confirmed in the study. Hyperandrogenemia in terms of significantly raised total testosterone levels was found in 30% of the PCOS women. However, no direct correlation of this increase with changes in lipid-lipoprotein profile could be observed. CONCLUSION: The study confirms the trend toward dyslipidemia among women with PCOS, particularly in parameters associated with cardiovascular risk. A significant association of obesity rather than raised testosterone with this dyslipidemia was also confirmed by the study.
