A Case Series of Follow-ups in COVID-Related Diabetes: Could the Damage in Beta Cells be Recovered?

SARS-CoV-2 infection may be related to new-onset diabetes and diabetic ketoacidosis (DKA). We describe a long-term follow-up of 3 cases presented in the Emergency Department with DKA and COVID-19. In 2 of them, the clinical course permitted withdrawal of insulin therapy during follow-up. The third case, a more serious one with pulmonary thromboembolism, continued to require bedtime insulin during the follow-up period. Such cases demonstrate that insulin treatment can control glucotoxicity and help beta cells recover after an acute insult such as COVID-19.
