Higher levels of serum chimerin levels in women with polycystic ovary syndrome (PCOS) may be associated with a higher risk for spontaneous abortion, according to a study published in Gynecological Endocrinology.
Researchers conducted a prospective study from May 2015 to December 2016 in China on 58 pregnant women with PCOS to evaluate whether there was a relationship between serum chemerin levels and the incidence of spontaneous abortions in women with PCOS.
The women were later placed into 1 of 2 groups (normal or abortion) on the basis of their clinical outcomes.
A total of 30 women had a normal pregnancy, and 28 had a spontaneous early abortion. The study did not find any significant differences between groups in fasting plasma glucose, total count, high-density lipoprotein, and triglyceride levels. There were also no differences observed in the mean serum level ratios of follicle-stimulating hormone, estradiol, progesterone, prolactin, luteinizing hormone, testosterone, and luteinizing hormone/follicle-stimulating hormone (P <.05).
Women with a higher body mass index later progressed to a spontaneous abortion compared with those who had a normal pregnancy (23.52±1.70 kg/m2 and 22.05±1.37 kg/m2; P <.05, respectively). There was a statistically significant association between higher levels of homeostasis model assessment for insulin resistance in women who experienced a spontaneous abortion compared with those with a normal pregnancy (P <.05). Finally, serum concentration levels in women who experienced an abortion were significantly higher than in women who experienced a normal pregnancy (247.01±80.04 ng/mL and 198.65±83.32 ng/mL; P <.05, respectively).
Researchers concluded that there was a positively associated risk with higher levels of chemerin and the risk for spontaneous abortion in women with PCOS (P <.001). Also, body mass index, fasting insulin, and homeostasis model assessment for insulin resistance were found to be positively associated with the risk for spontaneous abortion (P < .05). Clinicians should consider using chemerin as a potential predictability test to assess the subsequent risk for spontaneous abortion in women with PCOS.
