Plasma visfatin level in lean women with PCOS: relation to proinflammatory markers and insulin resistance.

Objectives: The present study was undertaken to investigate the association between plasma visfatin concentrations and inflammatory markers such as interleukin-6 (IL-6) and high-sensitive C-reactive protein (hsCRP) in company with several metabolic parameters in lean women with polycystic ovary syndrome (PCOS).

Methods: The study group consisted of 21 lean women with PCOS (BMI 20.74 +/- 1.74 kg/m(2)) and 15 healthy, normally menstruating women (BMI 20.85 +/- 2.08 kg/m(2) control group). PCOS was defined according to the Rotterdam criteria. Visfatin, IL-6, hsCRP, hyperandrogenism markers and metabolic markers were examined in all PCOS and control women.

Results: Plasma visfatin level in the PCOS group was higher than that in the control group. Plasma hsCRP and IL-6 levels in PCOS group were similar with the control group. Plasma visfatin levels were positively associated with total cholesterol, high density lipoprotein, hirsutism score, total testosterone and FAI. Plasma visfatin level was negatively associated with SHBG. However, there were no correlation between plasma visfatin level and IL-6 and hsCRP. In multivariate regression analyses, only FAI and high density lipoprotein-cholesterol (HDL-C) showed a significant association with serum visfatin.

Conclusion: Our data indicates that plasma visfatin levels are associated with HDL-C and markers of hyperandrogenism, but it is not associated with proinflammatory markers and insulin resistance in lean women with PCOS.
