Brief communication: Early appearance of islet autoantibodies predicts childhood type 1 diabetes in offspring of diabetic parents.
Ann. Intern. Med. 140, 882-886 (2004)
BACKGROUND: The development of type 1 diabetes mellitus is preceded by autoimmunity against islet beta cells. OBJECTIVE: To determine the risk for islet autoimmunity and childhood diabetes in offspring of affected parents. DESIGN: Prospective cohort study. SETTING: German BABYDIAB study. PARTICIPANTS: 1610 offspring of parents with type 1 diabetes. MEASUREMENTS: Autoantibodies to islet autoantigens were measured at 9 months, 2 years, 5 years, and 8 years of age. RESULTS: By 5 years of age, the frequency of islet autoantibodies was 5.9% (95% CI, 4.6% to 7.2%), the frequency of multiple islet autoantibodies was 3.5% (CI, 2.5% to 4.5%), and the frequency of diabetes was 1.5% (CI, 0.9% to 2.1%). The risk for diabetes was highest in offspring with multiple autoantibodies (40% within 5 years vs. 3% in offspring with single autoantibodies; P = 0.005). Progression to multiple islet autoantibodies was fastest in children who were autoantibody positive by age 2 years (P < 0.001), and progression to diabetes was inversely related to the age of positivity for multiple autoantibodies (P = 0.02). LIMITATIONS: The findings are limited to childhood diabetes in affected families. CONCLUSIONS: Childhood autoimmune diabetes is associated with autoimmunity that starts before 2 years of age.
