Diabetic ketoacidosis is a life-threatening complication associated with type 1 diabetes (T1D). Recent evidence suggests that SARS-CoV-2 could trigger diabetic ketoacidosis in type 1 diabetes susceptibility and previous insulitis; however, the data on SARS-CoV-2-infected patients with diabetic ketoacidosis as their type 1 diabetes are still limited. We report a 13-year-old Latinamerican male with symptoms and laboratory tests diagnostic of diabetic ketoacidosis and positive SARS-CoV-2 reverse transcription polymerase chain reaction, who required mild COVID-19 care management, fluid resuscitation, and insulin infusion at a regular dose, without further complications after the acute infection. Clinical/biochemical improvement allowed outpatient endocrinology follow-up with insulin therapy and continuous glucose monitoring. To our knowledge, we report the first case of diabetic ketoacidosis as the debut of type 1 diabetes in a Colombian pediatric patient with concurrent SARS-CoV-2 infection. Therefore, this report aims to contribute to the global research on SARS-CoV-2 and diabetic ketoacidosis and discuss the approach to these concomitant pathologies.
