Nivolumab-Induced Diabetic Ketoacidosis: A Case Report.

Nivolumab, an investigational monoclonal antibody targeting a specific immune pathway, has shown promise in treating various autoimmune diseases. However, like other immunomodulatory agents, it has potential side effects. This case report describes a rare adverse event of nivolumab-induced diabetic ketoacidosis (DKA) in a patient with a history of adrenal insufficiency secondary to nivolumab. The patient presented with symptoms of hyperglycemia, metabolic acidosis, and ketosis after receiving nivolumab therapy for 12 cycles. Prompt recognition and management of nivolumab-induced DKA are crucial to prevent complications and ensure patient safety.
