The association between anti-glutamic acid decarboxylase IgG and hemoglobin A1C among newly diagnosed type 1 diabetes of some Iraqi children in Karbala City
Abstract
Background: Type 1 diabetes mellitus (T1DM) is brought on by immune system dysfunction intolerance, invasion of beta cells by autoreactive immunological T cells, degradation of beta cell activity and survival, and extended exogenous insulin treatment. One of the circulation autoantibodies against antigens of pancreatic cell that produce insulin is glutamic acid decarboxylase (GAD IgG antibody) that indicate the stress and/or death of the islet cell in T1D. A blood glucose monitoring test called hemoglobin A1C (HbA1c) is used to determine the average blood sugar level over three months (February, March, and April of 2022). Objective: The purpose of this study is to assess the frequency of anti-GAD IgG and HbA1c in T1DM children, as well as their correlation. Materials and Methods: Seventy individuals with new-onset T1DM (confirmed by clinical signs, including increased urination, intense hunger, intense thirst, and abrupt weight loss, along with a random blood sugar test that is higher than 200 mg/dL and a fasting blood sugar test that is higher than 126 mg/dL) are male and female, ranging in age from 1 to 12 years. Blood was drawn for the biochemical and immunological tests (including HbA1c, fasting blood sugar, C-peptide, anti-islets antibodies, and anti-GAD antibodies). Results: Ninety-four percent of the T1DM patients had positive anti-GAD IgG with a mean concentration of 147 IU/mL, and 6% had negative anti-GAD IgG with a mean value of 9 IU/mL. At the same time, the findings of the current study’s calculation of HbA1c levels revealed that individuals with newly diagnosed T1DM had a total mean average of HbA1c of 10.53. Conclusion: Specifically in T1D that had arisen in extremely young children, autoimmunity was discovered to take part in the glycemic index expressed by glycated hemoglobin average.
