Objective: We aimed to investigate the association between serum levels of ghrelin and brain-derived neurotrophic factor (BDNF) with MetS and its components in premenopausal women.
Methods: 43 patients with MetS and 43 healthy controls participated in this study. Participants' body mass index (BMI), waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP) were measured. Serum levels of total cholesterol (TC), triglyceride (TG), low and high density lipoprotein cholesterol (LDL-C and HDL-C), fasting blood sugar (FBS), insulin, BDNF and ghrelin determined. Homeostasis model assessment insulin resistance index (HOMA-IR) was also calculated.
Results: Participants in MetS group had higher waist-to-hip ratios, elevated SBP and DBP, and higher serum levels of TG, FBS and insulin when compared with the control group. Serum ghrelin and BDNF levels were significantly lower in participants with MetS than in the healthier control subjects. There was a strong, positive correlation between serum ghrelin and BDNF levels. Both proteins negatively correlated with TG, FBS, HOMA-IR and positively with HDL-C. Furthermore, serum BDNF levels negatively associated with insulin levels.
Conclusions: The findings indicate that variations occur in the circulating level of ghrelin and BDNF proteins in MetS patients. A strong correlation between serum ghrelin and BDNF suggests that production, release or practice of these 2 proteins might be related mechanically.
