Little is known about its role in children. The current study aimed to investigate the potential role of CTRP3 in obese children and explore its relationships with insulin sensitivity, pancreatic β cell function, and obesity-related markers.Patients and methods: We studied the levels of serum CTRP3 in 48 obese and 36 normal weight pre-puberty children. The levels of blood pressure, lipids, glucose, and insulin were measured, and the values of HOMA-IR, HOMA-β and insulinogenic index were calculated. The correlations of these measurements with CTRP3 levels were analyzed.Results: In this study, we found that CTRP3 serum levels significantly decreased in obese children compared to controls, and insulin resistant obese subjects have lower CTRP3 levels in contrast with the non-insulin resistant obese subjects. Moreover, serum CTRP3 concentrations significantly decreased, while glucose and insulin concentrations significantly increased after a 3 hrs oral glucose tolerance test in obese children. Furthermore, Serum CTRP3 levels correlated negatively and significantly with BMI, triglycerides, systolic blood pressure, fasting insulin, glucose, HOMA-IR, HOMA-β and insulinogenic index in obese children.Conclusion: In summary, serum CTRP3 levels significantly decreased in obese children, and negatively correlated with insulin resistance and pancreatic β cell function indicators. Therefore, CTRP3 may play a protective role in the glucose homeostasis and tightly related to β cell function as well as obesity-related markers in obese children.Keywords: CTRP3, children, obesity, insulin resistance, pancreatic β cell function |
