Correlation between circulatory Kisspeptin and Adipokines in normal and over-weight Saudi females during menstrual cycle

Abstract

We analyzed the association between kisspeptin and plasma adipokines (leptin and adiponectin) in normal-weight and over-weight young females. Thirty young Saudi females, based on their body mass index (BMI), were divided into two groups (15 students/group) as (1) Normal weight (NW): BMI = 18.5–24.99 and (2) Over-weight/obese (OW): BMI ≥ 25. Serum adipokines (leptin, adiponectin) and kisspeptin levels were measured in early follicular, pre-ovulatory, and luteal phase in both groups with ELISA. Menstrual cycle phases were confirmed by serum estradiol levels. There was no association of kisspeptin with leptin in early follicular (r −0.34, P 0.31), pre-ovulatory (r −0.32, P 0.34) and luteal phase (r 0.21, P 0.54). Likewise, kisspeptin was not found to be correlated with adiponectin in early follicular (r 0.41, P 0.21), pre ovulatory (r 0.24, P 0.48), and luteal phase (r 0.40, P 0.23) when values recorded during different time points during the cycle were plotted with each other.
