Abstract

Aims: Type 2 diabetes mellitus (T2DM) is a highly prevalence disease that has a close relation with secretory factors such as adipokines and myokines. C1q tumor necrosis factor-α (TNF-α)-related protein 15 (CTRP15) is a paralogue paralogue of adiponectin that has a close relation with insulin resistance and inflammation. The present study aimed to assess circulating levels of CTRP15 in patients with T2DM in comparison with controls and thier association with inflammatory cytokines. Methods: This case–control study was performed on 80 T2DM patients and 80 controls which diagnosed according to the criteria of American Diabetes Association (ADA). Serum levels of CTRP15, adiponectin, TNF-α, and interleukin- 6 (IL-6) were determined using ELISA kits. Results: The results indicated higher concentration of CTRP15 in T2DM patients (103.17 ± 27.99) compared to the controls (66.11 ± 20.46, p < 0.001), while adiponectin decreased considerably in the patients compared to the controls (p < 0.001). Moreover, circulating levels of IL-6 and TNF-α elevated in the patients compared to the controls (p < 0.001). CTRP15 indicated independent association with BMI and adiponectin in the controls while, in the patients it demonstrated independent association with HOMA-IR and TNF-α. Conclusions: Higher concentration of CTRP15 in the patients and its relation with insulin resistance and inflammation suggested a relation of CTRP15 with the pathogenesis of diabetes. In addition, it seems likely that patients with T2DM had a CTRP15 resistance; however, future studies are necessary to prove this concept. © 2021, Springer Nature Switzerland AG.
