The Use of Dapagliflozin in the Treatment of Children With Severe Insulin Resistance.

Background: Managing severe insulin resistance (IR) is challenging, necessitating a multifaceted approach, including dietary restriction, exercise, and pharmacotherapy. This paper will detail our utilization of dapagliflozin in a series of cases involving patients with severe IR of various etiology and inadequate glycemic control. Case Studies: We describe six cases of extreme IR with distinct clinical diagnoses: four with Rabson-Mendenhall syndrome (RMS), one with IR type 1A, and a patient with type 1 diabetes mellitus (T1DM) and severe subcutaneous (SC) IR. These cases exhibit the observable characteristics of IR, characterized by an inability to effectively manage blood glucose (BG) with a standard treatment plan. Every case had a remarkable response to dapagliflozin. Subsequent assessment demonstrated improved HgbA1C, fasting glucose, insulin, and C-peptide concentrations. Furthermore, several cases demonstrated improvement in the clinical manifestations of IR following the administration of dapagliflozin, while others showed a reduction in the frequency of diabetic ketoacidosis (DKA). There were no documented adverse reactions with the use of dapagliflozin for a duration of 2-4 years in these patients. Conclusion: Dapagliflozin appeared both safe and effective as a standalone treatment or when used alongside other antidiabetes medications such as insulin in a case series of children with T1DM and severe IR or IR syndromes (IRS).
