RESUMO
OBJECTIVE: Diabetes mellitus has been recognized as one of the comorbidities that predict the severity of illness in patients infected with COVID-19. The characteristics of patients presenting with diabetic ketoacidosis (DKA) and COVID-19 infection have not been described. METHODS: We describe 5 patients with DKA and concomitant COVID-19 admitted to the intensive care unit of an academic medical center. Three patients had type 1 diabetes mellitus, and 2 patients had type 2 diabetes mellitus. RESULTS: While DKA with an infectious etiology is a common presentation, we observed that the patients with DKA precipitated by COVID-19 presented with atypical symptoms. COVID-19 infection was revealed during search for an etiology of DKA. CONCLUSION: It is prudent to have a low threshold to screen for COVID-19 infection in patients with DKA.
