ABSTRACT
INTRODUCTION:
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in reproductive-age women. Irisin is considered to play a role in metabolic disorder and PCOS. However, correlation between irisin and metabolic disorder in PCOS is not clear. MATERIAL ANDMETHODS:
This is a prospective study. Forty patients with PCOS and thirty patients without PCOS were recruited for in vitro fertilization and embryo transfer (IVF-ET). All PCOS women fulfilled all three Rotterdam consensus criteria. In each group, patients were also divided into obese and nonobese patients, and patients with or without dyslipidaemia.RESULTS:
Serum irisin level in PCOS patients was significantly reduced. Irisin level in obese PCOS patients was significantly lower than in nonobese PCOS patients. Irisin level in PCOS patients with dyslipidaemia was significantly higher than in PCOS patients with normal blood lipid profile. In both PCOS and control patients, serum irisin level was negatively correlated with body weight and waist-hip ratio (WHR). Moreover, serum irisin level was positively correlated with body fat rate, BAI, fasting plasma glucose (FPG) and HOMA-IR in PCOS patients. In addition, serum irisin level was positively correlated with HOMA-IR in control patients. In PCOS patients, body weight and HOMA-IR could predict the level of irisin. In control patients, body mass index (BMI) could predict the level of irisin. Expression of irisin in PCOS patients was lower than that in control patients. However, there was no significant difference of irisin expression between the subdivided groups in PCOS and control patients.CONCLUSIONS:
Taken together, the present findings enriched the knowledge about the role of irisin in metabolic dysfunction in PCOS patients.Key words
