Glucose control in type 1 diabetes and COVID-19.

Dear Editor,

We would like to share ideas on “Glucose control in home-isolated adults with type 1 diabetes affected by COVID-19 using continuous glucose monitoring [1].” Longo et al. concluded that “Young home-isolated patients with type 1 diabetes and COVID-19 showed a worsening of …infection [1].” In general, COVID-19 can affect glucose metabolism and it might result in elevation of blood glucose and hemoglobin A1C [2]. If there is no good diabetic care during COVID-19 illness, the DM patient under home isolation might have poor glucose control. In the present report, there are many confounding factors that might affect the observation on diabetic control. The severity of COVID-19 cases might be associated with outcome and there should be subgroup analysis. Additionally, medication used by patient should be mentioned. In our setting, Asia, many COVID-19 patients use alternative therapy and it can result in high blood glucose level. Furthermore, the use of telemedical care should be discussed. Whether the telemedicine care includes specific session on diabetic care is an interesting question.
