Abstract:
Background: Diabetes mellitus type 1 (T1D) is an autoimmune organ-specific disease with a wide range of clinical manifestations, in which the β cells of the pancreatic islets of Langerhans are destroyed by the action of autoreactive T lymphocytes and the formation of autoantibodies against β cell components. Among used serological markers of T1D, anti-glutamic acid decarboxylase antibodies (GAD65), anti-tyrosine phosphatase antibodies (IA2), islet cell antibodies (ICA), insulin autoantibodies (IAA) and anti-zinc transporter antibodies (Zn-T8) are of great significance. Objective: This study aimed to analyze presence of type 1 diabetes-related autoantibodies (GAD65, IA2, ICA, IAA and Zn-T8 and effects of age and gender on their occurrence in pediatric population. Methods: Sixty seven (N=67) T1D pediatric patients were included in the study. The levels of immunological parameters such as anti-glutamic acid decarboxylase antibodies (GAD-Ab), anti-tyrosine phosphatase antibodies (IA2-Ab), islet cell antibodies (ICA) and insulin autoantibodies (IAA) were determined by chemiluminescence immunoassay (CLIA) and anti-zinc transporter antibodies (Zn-T8-Ab) were determined by enzyme-linked immunosorbent assay (ELISA). For statistical analysis, we used SPSS statistical program. Results: Our study revealed that among 67 patients with T1D (40 male and 27 female), with an average age of 12,1±3,9 years. The average age of diabetes diagnosis was 6,15±3,29 years. 24 (35,8%) cases were positive for GAD65, 15 (22,4%) for ICA, 34 (50,7%) for IAA, 16 (23,9%) for IA2 and 36 (53,7%) for Zn-T8. The largest number of patients had single positive antibody, the most dominated among them was IAA dominated (40,9%), then Zn-T8 (31,8%). According to Spearman correlation test Zn-transporter shows a significant positive correlation with age of the participants (p=0.027) and disease duration (p=0.006). Anti IA2 shows significant negative correlation with HbA1c (p=0.043). Zn-transporter is associated with patients age and duration of T1D. Conclusion: In most cases, patients with T1D are positive for at least one of the specific autoantibodies. Zn-T8 is the most frequently detected and is an important serological marker of type 1 diabetes mellitus. Gender effects on autoantibodies seems to be insignificant, while age alongside disease duration shows important effects.
