Clinical Report: Prevalence of Autoimmune Disorders in Pediatric T1D
Overview
This study evaluated the prevalence and characteristics of autoimmune diseases in children and adolescents with type 1 diabetes mellitus (T1D). It found that 18.8% of subjects had at least one additional autoimmune disorder, with autoimmune thyroiditis and celiac disease being the most common.
Background
Children and adolescents with T1D are at an increased risk for additional autoimmune diseases, which can complicate their clinical management. Understanding the prevalence and timing of these comorbidities is crucial for early detection and improved long-term outcomes.
Data Highlights
Autoimmune Disease
Prevalence
Autoimmune Thyroiditis
12.7%
Celiac Disease
5.9%
Vitiligo
1.3%
Autoimmune Gastritis/Pernicious Anemia
0.15%
Autoimmune Hepatitis
0.15%
Key Findings
18.8% of children and adolescents with T1D had at least one additional autoimmune disease.
Autoimmune thyroiditis was the most prevalent comorbidity at 12.7%.
Celiac disease was identified in 5.9% of subjects.
Female sex was associated with a higher likelihood of additional autoimmune diseases (OR = 1.61).
Most autoimmune diseases were diagnosed concurrently with or after T1D onset, clustering within the first two years.
Age at diagnosis of T1D was positively correlated with the age at diagnosis of autoimmune thyroiditis and celiac disease.
Clinical Implications
The findings suggest that routine screening for autoimmune diseases, particularly thyroiditis and celiac disease, should be intensified in pediatric patients with T1D, especially in females. Early detection may facilitate better management of these comorbidities.
Conclusion
Autoimmune comorbidities are common in pediatric T1D.
