Abstract
Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2, poses a significant threat to public health worldwide, and diabetes is considered a risk factor for the rapid progression and poor prognosis of COVID-19. Limited immune function is a clinical feature of COVID-19 patients, and diabetes patients have defects in innate and adaptive immune functions, which may be an important reason for the rapid progression and poor prognosis of COVID-19 in patients with diabetes. We review the possible multiple effects of immune impairment in diabetic patients on the immune responses to COVID-19 to provide guidance for the diagnosis and treatment of diabetic patients with COVID-19.
Core Tip: Diabetes is an important predictor of coronavirus disease 2019 (COVID-19) morbidity and mortality. The immune response impairment presented by diabetes mellitus (DM) may be among the underlying mechanisms of the association between diabetes and COVID-19. DM patients with uncontrolled hyperglycemia are more prone to develop severe COVID-19 due to T cell dysfunction. Therefore, DM is often associated with impaired innate and adaptive immune function, thus greatly increasing the risk of severe acute respiratory syndrome coronavirus 2 infection in DM patients.
