Serum chemerin level in women with PCOS and its relation with the risk of spontaneous abortion.

BACKGROUND AND AIM: Insulin resistance (IR) was recognized as a risk factor for the occurrence of abortion in patients with polycystic ovary syndrome (PCOS). Chemerin was an adipokine which could induce IR and associated with reproductive process closely. However, few studies have inquired the relativity between chemerin and the occurrence of abortion in patients with PCOS. The aim of this study was to evaluate the relationship between serum chemerin and the occurrence of abortion in women with PCOS. METHODS: We recruited 198 women with PCOS to participate in our study. On the third day of menstrual cycle or a random day in women with amenorrhea, we obtained their venous blood and measured the fasting insulin, fasting plasma glucose, total cholesterol, high density lipoprotein cholesterol, triglyceride, chemerin, and hormones including FSH, E2, P, PRL, LH, and T. Additionally, BMI, HOMA-IR and LH/FSH of each subject were calculated. Finally, 58 of them were included in the study, in which 30 of them had normal pregnancy and the other 28 had an early miscarriage. We compared the biochemical characteristics between the normal pregnancy group and abortion group by independent-samples t test. RESULTS: In our study, those with a normal pregnancy had a lower level of BMI, FINs, HOMA-IR, and chemerin compared to abortion patients (p < .05). After adjusted for BMI, only chemerin was associated with the occurrence of abortion in PCOS patients (p < .05). CONCLUSIONS: Serum chemerin level is associated with the occurrence of abortion in patients with PCOS. Thus, serum chemerin may serve as a biomarker to identify pregnant women with PCOS who are at particular risk for later abortion, and who may benefit from prevention strategies.
