New onset of diabetes in a child infected with COVID-19: a case report

BACKGROUND: Diabetic ketoacidosis (DKA) is a serious complication of type 1 diabetes. A few studies have reported that COVID-19 is associated with the development of new-onset diabetes. Here, we present an infected child with new onset diabetes leading to DKA. CASE PRESENTATION: A 10-year-old patient with respiratory distress admitted to the Emergency Department of our center. The patient’s COVID-19 Polymerase Chain Reaction (PCR) test was positive and also biochemical analyses confirmed that he had DKA. Despite standard initial treatments, ketoacidosis remained resistant; hence we prescribed oral bicarbonate (40 cc every 8 h) to treat the patient's refractory acidosis. Due to the patient’s improvement, he was discharged after 10 days (7 days in the PICU), receiving outpatient enoxaparin (for a week) and ongoing subcutaneous insulin. CONCLUSION: We report an interesting case of a child with COVID-19 infection precipitating presentation with new onset diabetes. Due to refractory acidosis, starting oral bicarbonate treatment after 2 days improved acidosis and tachypnea in the patient. The patient’s medical team suggest close biochemical monitoring, prescribing enoxaparin for high level of D-dimer, and ordering oral bicarbonate acidosis persists.
