Drug Induced Diabetes Mellitus in Pediatric Acute Lymphoblastic Leukemia: Approach to Diagnosis and Management

Corticosteroids and l-asparaginase used in the treatment of pediatric acute lymphoblastic leukemia (ALL) can cause drug-induced diabetes mellitus (DIDM). DIDM can lead to dyselectrolytemia, a higher risk of infections including cellulitis, bacteremia, fungemia, and a higher incidence of febrile neutropenia and may have an impact on the outcome of ALL. Literature on the management of DIDM among children with ALL is sparse and the diagnostic criteria for pediatric diabetes should be carefully applied considering the acute and transient nature of DIDM during ALL therapy. Insulin remains the standard of care for DIDM management and the choice of Insulin regimen (stand-alone Neutral Protamine Hagedorn or basal bolus) should be based on the type and dose of steroids used for ALL and the pattern of hyperglycemia. A modest glycemic control (postmeal 140 to 180 mg/dL, premeal <140 mg/dL) to prevent complications of hyperglycemia, as well as hypoglycemia, would be the general approach. This review is intended to suggest evidence-based practical guidance in the diagnosis and management of DIDM during pediatric ALL therapy.
