Adropin in women with polycystic ovary syndrome
Abstract
Introduction: Women with polycystic ovary syndrome (PCOS) frequently develop metabolic complications. Among the newly found factors responsible for metabolic disorders, adropin seems to be of a great significance.
Material and methods: In total 134 women aged 17–45 years were enrolled. The PCOS group consisted of 73 women, diagnosed on the basis of Executive Committee of the European Society of Human Reproduction and Embryology — American Society for Reproductive Medicine (ESHRE-ASRM) criteria. All PCOS women presented phenotype A of PCOS. The control group consisted of 61 women with regular menstrual cycles, matched for nutritional status. All women underwent anamnesis, physical examination, anthropometric measurements, abdominal and transvaginal ultrasound, and dual-energy X-ray absorptiometry (DXA). Serum adropin levels were determined by ELISA. Biochemical [fasting glucose and insulin, oral glucose tolerance test, lipid and sex hormone-binding globulin (SHBG)] and hormonal (testosterone, androstenedione, luteinizing hormone, follicle-stimulating hormone and oestradiol) measurements were performed. Insulin resistance indices [(Homeostasis Model Assessment for Insulin Resistance (HOMA-IR), Quantitative Insulin Sensitivity Check Index (QUICKI), Matsuda] and free androgen index (FAI) were calculated according to the standard formula.
Results: Serum adropin levels were lower in the PCOS group (0.475 ± 0.200 vs. 0.541 ± 0.220, p = 0.069), but the results were not statistically significant. Positive correlations among adropin and androstenedione levels were observed in the PCOS group (r = 0.27, p = 0.025).
Conclusions: Women with PCOS have a different metabolic profile in comparison to women without this syndrome. We did not observe a statistically significant difference in adropin concentration between the PCOS and the healthy control group. Therefore, more studies regarding adropin in PCOS are needed.
