New-Onset Diabetes with Ketoacidosis Precipitated by COVID-19 in Children: A Report of Two Cases

BACKGROUND AND AIMS: There is growing evidence that the 2019 coronavirus disease (COVID-19) is emerging as a potential trigger virus for the development of diabetes mellitus in children. This can occur even in patients without factors predisposing to impaired glucose metabolism. Here, we report two rare cases of diabetic ketoacidosis revealing new-onset diabetes and precipitated by COVID-19. These cases are reported in view of their rarity and originality. The relationship between type 1 diabetes mellitus and COVID-19 is discussed. RESULTS: Two children developed symptoms suggestive of diabetic ketoacidosis preceded by polyuria, polydipsia, and asbestos. There is a documented COVID-19 infection in the parents of the 2 children. An asymptomatic infection was detected in the 2 patients on the basis of a reverse transcription polymerase chain reaction (RT-PCR) test. Thoracic imaging and inflammatory workup were negative in both cases. Both patients responded well to treatment, including rehydration regimens and intravenous insulin. On the 2nd day of their hospitalization, they were transferred to several injections of subcutaneous insulin with therapeutic and nutritional education from the parents. After about 4 weeks, their insulin requirements probably decreased due to the diabetes honeymoon. CONCLUSION: COVID-19 can induce acute onset diabetes and diabetic ketoacidosis in children. More research data are needed to improve our knowledge of this constellation and to guide the most appropriate therapies.
