New onset diabetes with diabetic ketoacidosis in a child with multisystem inflammatory syndrome due to COVID-19.

Introduction Multisystem inflammatory syndrome in children (MIS-C) is a unique clinical complication of SARS-CoV-2 infection observed in pediatric patients. COVID-19 is emerging as a potential trigger for the development of diabetes in children. Here, we report a patient presenting with MIS-C and new onset diabetes, and discuss the implication and clinical management of these concomitant conditions. Case presentation An eight-year-old female presented with hyperglycemia, ketosis and metabolic acidosis consistent with diabetic ketoacidosis (DKA) in the setting of fever, rash, respiratory distress, hemodynamic instability, reduced systolic function with dilation of the left anterior descending artery, and positive SARS-CoV-2 antibodies suggestive of MIS-C.
