Abstract

OBJECTIVE : The aim of this study was to study the effects of metformin therapy on serum chemerin levels in some phenotypes of polycystic ovarian syndrome cases, and to correlate chemerin levels with insulin resistance parameters and with hormonal profile.
METHODS : This study was carried on 100 polycystic ovary cases and 70 control women. These cases were further subdivided into obese and normal weight cases. Fasting serum chemerin was measured by Enzyme-Linked Immunosorbent Assay method. Data were analyzed using SPSS for Windows 7.
RESULTS : Before metformin therapy, the serum chemerin were significantly increased in PCOS cases as compared with the control cases. Also, a significantly higher chemerin levels were found in obese polycystic ovarian syndrome cases as compared with normal weight cases with polycystic ovarian syndrome. The serum chemerin levels were significantly positively correlated with glucose levels, insulin levels, and HOMA-IR in polycystic ovarian syndrome cases. After three months of metformin therapy, the serum chemerin, insulin, and HOMA-IR concentrations were significantly decreased in polycystic ovarian syndrome cases as compared with the levels before therapy.
CONCLUSIONS : The serum chemerin levels were significantly higher in cases of PCOS cases as compared with the controls. Metformin therapy resulted in a significant decrease in chemerin levels in polycystic ovarian syndrome cases. The analysis of Receiver Operation Characteristic curves of serum chemerin suggested that serum chemerin levels may be of value to evaluate the polycystic ovarian syndrome cases under various methods of treatments.
