Objective:
To investigate the immunological features of fulminant type 1 diabetes.
Methods:
Twenty patients with fulminant type 1 diabetes (F1D) were recruited based upon the criteria proposed by Hanafusa, and 40 patients with classical type 1 diabetes were matched with age, gender and duration for comparison. GADA, IA2A and ZnT8A were determined with radioligand assay, and GAD-reactive T cells were measured by enzyme-linked immunospot (ELISPOT) assay. The HLA-DQ were analyzed by sequence-based genotyping (SBT).
Results:
Eight of 20 patients with F1D were antibody-positive, including 7 GADA positive, 4 ZnT8A positive, and 3 both GADA and ZnT8A positive. The index of 3 GADA positive patients were less than 0.4 at first visit, two turned to be negative by two or three years. While the GADA index of the patient was 0.343 at onset and increased to 1.467 three years later. Among subjects with F1D (3/6) and classical type 1 diabetes (3/6), were recorded significant GAD-stimulated responses by ELISPOT assay. The frequencies of HLA-DQA1*0102-DQB1*0601 and DQA1*03-DQB1*0401 were significantly higher in F1D than those in classical type 1 diabetes (P = 0.005, P = 0.035, respectively).
Conclusion:
Humoral and cellular immunoreactivity and susceptible HLA-DQ genotype existed in part of F1D patients, indicating autoimmunity may involve in the pathogenesis of F1D.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
