Evaluation of the serum level of CTRP-3 and CTRP-6 in patients with Hashimoto's disease and correlation with thyroid hormones and lipid profile.

Objectives: Numerous studies show that the adipokines play a role in on the thyroid axis. The aim of this study was the evaluation of serum level of CTRP-3 and CTRP-6 as a member of the adipokines family in patients with Hashimoto's.

Methods: The levels of CTRP-3 and CTRP-6 were evaluated with enzyme-linked immunosorbent assay in 70 subjects (35 newly diagnosed Hashimoto's thyroiditis and 35 healthy subjects). Their relationship with the thyroid hormone and some biochemical factors was analyzed.

Results: The levels of CTRP3 and CTRP6 in patients with Hashimoto's disease were higher than those in the control group (p<0.05). There was a significant positive correlation between CTRP3 and TSH levels (r=0.286 and p=0.017). There was a significant relationship between CTRP3 and Fasting Blood Sugar (r=0.249 and p=0.038). There was a significant inverse negative correlation between CTRP6 levels and T3 (r=-0.269 and p=0.024), and T4 (r=-0.272 and p=0.023). Moreover, there was a significant positive correlation between CTRP6 serum levels and TSH serum levels (r=0.397 and p=0.001). There was a significant positive correlation between CTRP6 levels and Cholesterol (r=0.351 and p=0.003), and LDL (r=-0.244 and p=0.042).

Conclusions: Finally, our results demonstrated that serum levels of CTRP3 and CTRP6 are higher in patients with Hashimoto's compared to the control group and probably play a role in the pathogenesis of Hashimoto's thyroiditis.
