Clinical Features and HLA Genetics Differ in Children at Type 1 Diabetes Onset by Hispanic Ethnicity.
Context: Type 1 diabetes incidence continues to increase in children, especially among Hispanic Whites (HW).
Objective: We investigated the clinical, immunologic, and genetic characteristics of HW and Non-Hispanic White (NHW) children that presented at type 1 diabetes diagnosis.
Methods: In this single-center, observational study, children who were diagnosed with type 1 diabetes (<20 years old) and tested for islet autoantibodies within 1 year of diagnosis were included in the study and divided into two groups by Hispanic ethnicity.
Results: Of 1297 children, 398 HW children presented with a younger age at diabetes onset (10.2 ± 3.9 vs. 11.1 ± 4.1 years, p<0.001) and more diabetic ketoacidosis (62.4% vs. 51.9%, p<0.001) compared to NHW children (n=899). There was no difference in sex, A1c levels, or the number and prevalence of islet autoantibodies between the two cohorts. A subset of our cohort was HLA typed as specific alleles confer strong genetic risk for type 1 diabetes (e.g., HLA-DR4 and DQ8). Among 637 HLA-typed children, HW children had a significantly higher prevalence of the DR4-DQ8 haplotype compared to NHW children (79.1% vs. 60.1%, p<0.001), and this frequency was much higher than a reference Hispanic population (OR = 6.5, 95% CI 4.6-9.3).
Conclusions: Hispanic White children developing type 1 diabetes have a high prevalence of HLA DR4-DQ8, which can be utilized to select individuals for immune monitoring with islet autoantibodies to lessen diabetic ketoacidosis and potentially prevent diabetes onset.
