Role of Betatrophin and Inflammation Markers in Type 2 Diabetes Mellitus, Prediabetes and Metabolic Syndrome.

Objective: To determine the association of betatrophin and inflammation factors in metabolic diseases such as diabetes, impaired fasting glucose, impaired glucose tolerance and metabolic syndrome.

Study Design: A cross-sectional, analytical study.

Place And Duration Of Study: Fırat University Medical School between April 2017 and December 2020.

Methodology: The study included 20 patients with type 2 diabetes mellitus, 20 patients with impaired fasting glucose (IFG), 20 patients with impaired glucose tolerance (IGT), 20 patients with metabolic syndrome (MetS), and a control group consisting of 20 healthy individuals. Anthropometric, fasting serum biochemical data were collected. Circulating betatrophin, and inflammation markers were measured by enzyme-linked immunosorbent assay (ELISA). The association of betatrophin, TNF-alpha, and IL-6 levels between groups were performed with One-way ANOVA and post-hoc Tukey HSD test.

Results: Significantly higher levels of circulating betatrophin were observed in IFG, IGT, And MetS groups compared to healthy controls (p=0.017). There were significantly difference TNF-α levels in IFG, IGT, and MetS groups compared to healthy controls (p<0.001). The levels of IL-6 were significantly higher in MetS group than healthy controls (p=0.007).

Conclusion: The circulating betatrophin and TNF-α levels were increased in MetS, IFG and IGT. IL-6 was decreased in MetS compared to the healty controls. Further studies are needed to elucidate the role of betatrophin and inflammatory parameters in the development of T2DM and prediabetic syndromes, whether betatrophin could have clinical applications in the development of new antidiabetic agents.
