<abstract xmlns="http://www.w3.org/1999/xhtml"> Objective. The aim of the present study was to determine the irisin levels in patients with the type 1 diabetes mellitus (T1DM) and to examine the relation of irisin levels with the inflammation and autoimmunity.Methods. This study included 35 cases diagnosed with T1DM and 36 healthy volunteers. Antiglutamic acid decarboxylase (anti-GAD), islet cell antibody (ICA), and insulin autoantibody levels were measured in patients at the time when they were included into the study and recorded from the patient files. Serum irisin levels were measured by ELISA kit.Results. The median irisin levels were determined higher in T1DM group compared to the control one (6.8 ng/ml vs. 4.8 ng/ml, p=0.022; respectively). Median irisin levels were higher in anti-GAD (p=0.022) and ICA (p=0.044) positive groups compared to negative groups. In T1DM group, irisin levels displayed positive correlation with glycosylated hemoglobin (HbA1c) (r=0.377, p&lt;0.001) and anti-GAD (r=0.392, p=0.020) and negative correlation with creatinine (r=-0390, p=0.021). In multivariate regression model, HbA1c (B±SE: 2.76±17683, p&lt;0.001), and anti-GAD (B±SE: 2.311±0.610, p=0.001) were determined as independent predictors for predicting the irisin levels.Conclusion. In patients with T1DM, which chronic inflammation and autoimmunity take part in their etiopathogenesis, anti-GAD levels were an independent risk factor for the irisin. Th is may suggest that factors such as inflammation and autoimmunity can be effective in the synthesis of irisin.</abstract>
