Abstract

Background: Manifestations and outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are not well documented in patients with common variable immunodeficiency disorder (CVID).

Methods: A Danish nationwide retrospective clinician-reported survey.

Results: Eleven patients with CVID and SARS-CoV-2 infection were identified. The median age was 50 years (range 22-72). All were on immunoglobulin replacement therapy. Eight patients had other pre-existing co-morbidities. Three patients were asymptomatic during the SARS-CoV-2 infection while seven developed mild coronavirus disease 2019 (COVID-19). One patient had more severe disease with hypoxia and required oxygen therapy. This patient had multiple co-morbidities including well known risk factors for severe COVID-19. All patients recovered.

Conclusions: The results suggest that CVID may not be a risk factor for severe COVID-19. However, further monitoring of this immunodeficient population is needed to confirm our observation.

Keywords: COVID-19; SARS-CoV-2; common variable immunodeficiency; inborn errors of immunity; primary immunodeficiency.
