Abstract:

Objective To explored the relationship between irisin and newly diagnosed type 2 diabetes mellitus (T2DM). Methods Forty newly diagnosed T2DM patients were collected as the T2DM group. During the same period, 40 healthy subjects in the physical examination center of the hospital were collected as the control (NC) group. Clinical indexes, metabolic indexes and serum concentrations of inflammatory cytokines interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and irisin were detected in the two groups. The differences of above indexes were analysed in the two groups. The correlation between irisin and the above indexes was analyzed. Logistic regression was used to analyze the relationship of irisin and newly diagnosed T2DM. Results Compared with the NC group, serum levels of cytokines IL-1β, IL-6, TNF-α and IFN-γ were significantly increased in the T2DM group (P<0.05), and the serum level of irisin was significantly decreased (P<0.05). The serum irisin was negatively correlated with FPG, 2 h PG, HbA1c, HOMA-IR, IL-1β and IFN-γ (P<0.05). The increased level of irisin was a protective factor for T2DM (P<0.01). Conclusion The serum level of irisin decreases in newly diagnosed T2DM patients. Irisin is closely related to glucose metabolism, insulin resistance and inflammation, which may have some protective effects on T2DM.
