Circulating omentin-1 levels and inflammation in polycystic ovary syndrome.

OBJECTIVES
The aim of the study was to analyze interrelation between plasma omentin-1 levels and nutritional status and inflammation in PCOS.


MATERIAL AND METHODS
A cross-sectional study involving 86 PCOS (47 obese) and 72 Non-PCOS women (41 obese) determined anthropometric parameters and body composition. Serum glucose, insulin and omentin-1, TNF-α, sTNFRs, IL-6 and sR-IL6 were measured in the fasting state.


RESULTS
Plasma omentin-1 levels were significantly lower in the PCOS than in the Non-PCOS group and both corresponding normal weight and obese subgroups. In three analyzed least-angle regression (LARS) models the lower plasma omentin- 1 levels was associated with PCOS occurrence, higher circulating TNF-α and lower IL-6 levels.


CONCLUSIONS
Suppressed omentin-1 levels in PCOS are characteristic for this disturbance and proinflammatory cytokines are factors modifying secretion of this adipokine.
