SARS-CoV-2 infection in patients with inborn errors of immunity due to DNA repair defects

Acta Biochim Biophys Sin (Shanghai). 2022 Jun 25;54(6):836-846. doi: 10.3724/abbs.2022071.


Clinical information on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with inborn errors of immunity (IEI) during the current Coronavirus disease 2019 (COVID-19) pandemic is still limited. Proper DNA repair machinery is required for the development of the adaptive immune system, which provides specific and long-term protection against SARS-CoV-2. This review highlights the impact of SARS-CoV-2 infections on IEI patients with DNA repair disorders and summarizes susceptibility risk factors, pathogenic mechanisms, clinical manifestations and management strategies of COVID-19 in this special patient population.

Keywords: COVID-19; DNA repair mechanism; inborn errors of immunity; primary immunodeficiency.
