Insights
Two patients with Chronic Granulomatous Disease (CGD) experienced severe Coronavirus Disease 2019 (COVID-19) infections. This challenges the assumption that CGD offers protection against severe viral illnesses, suggesting a unique COVID-19 pathogenesis.
Area of Science:
- Immunology
- Infectious Diseases
- Genetics
Background:
- Coronavirus Disease 2019 (COVID-19) is a global pandemic.
- Chronic Granulomatous Disease (CGD) involves impaired phagocyte function, leading to recurrent infections.
- CGD patients typically have normal viral immunity, and impaired neutrophil function was hypothesized to be protective against severe COVID-19.
Abstract:
A novel coronavirus disease known as Coronavirus Disease 2019 (COVID-19) has spread quickly throughout the world, and it was declared a pandemic in March 2022. Chronic granulomatous disease (CGD) is a diverse group of genetic disorders characterized by recurrent bacterial and fungal infections, resulting in granulomas due to the inability of phagocytes to destroy microbes. Even though it is thought that impaired neutrophil activity is a protective mechanism against severe COVID-19-induced cytokine storms and hyper-inflammatory responses, patients with CGD have normal immunity to most viruses. Here, we present two CGD patients who were hospitalized due to severe COVID-19 infections, which suggests that COVID-19 might have a different pathogenesis than other viruses.
