Hypogammaglobulinemia is a heterogeneous group of innate and acquired antibody deficiency with variable disease severity, recurrent pneumonia, and bronchiectasis. The outcome of COVID in patients with hypogammaglobulinemia is variable depending on age, comorbidities, type of immunodeficiency, and use of immunoglobulins. We report the favorable outcome of two family members diagnosed with DNAJC17-related retinitis pigmentosa and hypogammaglobulinemia syndrome and infected with SARS-CoV-2 following contact with their mother who had COVID-19. We describe the different immune dysfunction in these patients and their impact on the course and management of SARS-CoV-2 infection.
Keywords: COVID-19; hypogammaglobulinemia; outcome; retinitis pigmentosa.
