RESUMO
AIM: To explore the serum levels of visfatin (VF) and tumor necrosis factor-alpha (TNF-α) in the patients with pre-eclampsia (PE) and their correlation with insulin resistance (IR).METHODS: The severe PE pa-tients (n =30), mild PE patients (n =30) and normal pregnant women (n =40) were selected according to the classifica-tion standard of PE.The serum levels of VF and TNF-αwere measured by ELISA.Fasting plasma glucose (FPG) and fasting insulin (FIns) were detected by glucose oxidase method and radioimmunoassay, respectively.Triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol ( HDL-C) and low-density lipoprotein cholesterol ( LDL-C) were measured by an automatic biochemical analyzer.According to calculating the mean arterial pressure (MAP), body mass index (BMI) and homeostatic model assessment for insulin resistance index (HOMA-IR), the correlation between IR and the levels of serum VF as well as TNF-αwere analyzed.RESULTS: The levels of VF and TNF-αin severe PE group and mild PE group were significantly lower than those in normal pregnancy group (P rum VF and TNF-α(P <0.05).CONCLUSION: Serum levels of VF and TNF-αare closely related to IR.
