Complement c1q tumor necrosis factor-related protein 3 a novel adipokine, protect against diabetes mellitus in young adult Egyptians

C1q/TNF-related protein-3 (CTRP3) is a novel adipokine with anti-inflammatory and a multitude of biological effects on glucose and lipid metabolism however, the influence of CTRP3 on incidence of diabetes mellitus remain unclear. This study investigated the effects of CTRP3 levels in obese and normal body weight young adults on insulin resistance and occurrence of diabetes mellitus. Subjects and methods: In this case control study, Serum levels of CTRP3, HbA1c, Lipid profile, glucose and insulin levels were determined in 75 obese and 68 normal body weight individuals. Results: In obese young adults CTRP3 concentrations were decreased compared to normal body weight young adults (NBW). The association between reduction of CTRP3 concentrations and the presence of diabetes is statistically significant. CTRP3 showed significant negative correlation with BMI, HOMA-IR and triglycerides as well as positive correlations with HDL - cholesterol while there is no association between CTRP3 and BMI within the NBW group. Higher HbA1C, HOMA-IR, and risk of diabetes development within obese subjects were related to lower CTRP3 concentration. Conclusions: This study shows that reduction of CTRP3 concentrations is likely to bring a concomitant increase in risk of diabetes in obese and normal body weight young adults. Decrease in CTRP3 concentration may have an essential role in the pathophysiology of metabolic disorders concomitant to obesity. (c) 2018 Diabetes India. Published by Elsevier Ltd.
