RESUMO
INTRODUCTION: Diabetic ketoacidosis is the most important metabolic emergency in children. Children mimic many syndromes with a combination of nonspecific symptoms during the COVID-19 pandemic. Many syndromes are triggered by changes in children's body conditions. Reporting specific cases can improve the diagnosis process. The present study reports an 18-month-old paediatric case of COVID-19 who presented ketoacidosis (DKA) symptoms. CASE PRESENTATION: The case is an 18-month-old child with fever and diarrhoea from 3 days before, who did not respond to outpatient treatment. On the day of the visit, he suffered from deep and abdominal breathing and decreased level of consciousness and sugar levels at admission of 420 mg/dl. He was then admitted with the initial diagnosis of DKA and had a positive PCR test result for COVID-19. CONCLUSIONS: Considering the non-specific symptoms of COVID-19, general practitioners and paediatricians are recommended that special attention be paid to these symptoms, especially those that are similar to life-threatening syndromes. They also should not easily ignore these symptoms and follow up patients and their recovery status and, if patients do not recover, consider the risk of COVID-19 given the current COVID-19 pandemic.
