Serum Level of Inhibin B and Kisspeptin, as well as Their Correlation with Biochemical Factors in Obese Adult Patients

Obesity is one of the most important global health problems causing serious health risks and early death in human. It is also associated with disturbance of homeostasis of hormones and immunological biochemical factors inside the human body. This study aimed to evaluate the serum level of inhibin B and kisspeptin among Iraqi obese adult people and other biochemical parameters correlated with obesity. Inhibin B and levels of kisspeptin were evaluated in the samples of serum from 40 Iraqi obese adult patients and 30 healthy non-obese individuals. A significant decrease (P<0.0001) was observed in the kisspeptin level in both males and females, compared to the control group. Moreover, inhibin B decreased significantly in obese females only (P<0.001), while there was no differences between males and the control group in this regard. Finally, body mass index, serum glutamic pyruvic transaminase (SGPT), and leptin showed negative correlation with kisspeptin (0.01, 0.5, and 0.01), respectively. However, a positive association was observed with the level of Ca in the serum. On the other hand, inhibin B confirmed a positive correlation with SGPT. The present study revealed a significant increase in inhibin B and kisspeptin, with SGPT and Ca in the serum of obese patients, which could lead to complications and health problems among these patients.
