Background: Our aim was to investigate levels of lipocalin-2 and its relationship with metabolic factors in women with polycystic ovary syndrome (PCOS).
Materials/subjects and methods: In this cross-sectional study, two groups of women were studied: group 1 consisted of women with PCOS (n=30), and group 2 consisted of control women with normal ovulatory function (n=30). The circulating levels of lipocalin were measured.
Results: Serum lipocalin was significantly higher in PCOS subjects. We found a close correlation between lipocalin and insulin, lipocalin and HOMA-IR, lipocalin and testosterone and lipocalin and DHEAS. A cut-off level of >39.54 ng/ml for serum lipocalin has a predictive value for insulin resistance of 81% sensitivity and 82.1% specificity.
Conclusion: In our study, lipocalin-2 levels were found to be significantly higher in women with PCOS compared to body mass index-matched controls. Serum lipocalin-2 may prove to be a useful marker for insulin resistance in patients with PCOS.
