Early High-Dose Vitamin D and Residual β-Cell Function in Pediatric Type 1 Diabetes

The project aims to study the effect of early high-dose vitamin D supplementation on type 1 diabetes in children and adolescents receiving intensive insulin therapy. The results may lead to major changes in the early treatment of type 1 diabetes, with special emphasis on the use of vitamin D to improve the function of residual β-cells and maintain standardized insulin therapy for these patients. The overall goal is to reduce the long-term complications of type 1 diabetes.
