The Role of Imatinib in Pediatric Type 1 Diabetes.

We report the first case of imatinib use in an adolescent with diabetes and suggest that it impacts the natural course of disease. A 14-year-old male patient presented in diabetic ketoacidosis (DKA) and was diagnosed with presumed autoantibody-negative type 1 diabetes (T1D) as well as myeloid neoplasm with platelet-derived growth factor receptor beta (PDGFRB) rearrangement. After starting exogenous insulin and imatinib, he experienced a 1.7-point reduction in glycated hemoglobin (HbA1c) and a 71% reduction in insulin requirement with sustained partial diabetes remission. Our case suggests imatinib as a potential therapeutic agent for pediatric T1D.
