Tipped Over the Edge: A Case of Diabetes Ketoacidosis Precipitated by High-Dose Steroids in the Setting of a Large Peritonsillar Abscess.

ABSTRACT

Peritonsillar abscess is an infection of tonsillar soft tissue which can spread into additional neck structures leading to symptoms of fever, sore throat, dysphagia, and airway compromise. We describe a case of diabetic ketoacidosis in a patient with a history of uncontrolled type II diabetes mellitus admitted for a peritonsillar abscess who received intravenous steroids for management of the abscess swelling. The patient was treated with an insulin drip, hydration, and electrolyte replacement with a resolution to his anion gap and metabolic acidosis. Diabetic ketoacidosis occurs during increased gluconeogenesis leading to ketosis and metabolic acidosis which can be a life-threatening condition if not quickly recognized and treated. This case highlights the importance of monitoring and treating elevated blood glucose in acutely ill patients receiving steroid therapy.
