Abstract
Neuregulin 4 (NRG4) is an adipokine that is synthesized in many tissues and has been shown to be associated with the development of obesity and metabolic disorders in animals and humans. The aim of this study is to investigate the relationship between serum NRG4 levels and various metabolic parameters in women with PCOS. This cross-sectional study included 40 women with PCOS and 40 age- and BMI-matched controls without PCOS. NRG4, fasting blood glucose (FBG), insulin, hs-CRP, LDL-C, HDL-C, SHBG, DHEA-SO4 and total-testosterone levels were measured in all the participants. HOMA-IR was used to calculate the insulin resistance. Serum NRG4 levels were higher in women with PCOS than in healthy women (24.89 ± 9.32 [ng/mL] vs. 18.98 ± 6.40 [ng/mL], p = 0.002). FBG, LDL-C, HDL-C, LH, SHBG, FAI, DHEA-SO4, insulin, hs-CRP, HOMA-IR and total-testosterone levels were significantly higher in women with PCOS than controls. Circulating NRG4 levels were positively correlated with HOMA-IR, insulin and hs-CRP for both groups. There was a positive correlation between NRG4 and FBG in the PCOS group. HOMA-IR and hs-CRP were associated with NRG4. The high concentration of circulating NRG4 in PCOS may be associated with insulin resistance and low-grade chronic inflammation.
