Immunological predictors of type 1 diabetes mellitus (literature review)

Background: Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease characterized by insulin deficiency due β-cell destruction and following hyperglycaemia. Specific markers of T1DM are pancreatic islet-targeting autoantibodies that are found months to years before symptom onset, and can be used to identify individuals who are at risk of developing T1DM. Aim: The study is aimed at the review of current knowledge of diabetes-related autoantibodies as biomarkers of T1DM. Materials and methods : Foreign and national clinical studies on this topic were included. PubMed, Medline and eLibrary were searched. Results: Modern ideas about known diabetes-specific autoantibodies as markers of autoimmune inflammation of β-cells of the pancreas were discussed. The analysis of their independent diagnostic value in predicting the occurrence of T1DM were carried out. Conclusion: There is no unified concept in the literature on this issue. Current data on autoantibodies in T1DM show a significant individual variability in the timing, dynamic changes and autoantibody composition in T1DM progression.
