Abstract
Chronic granulomatous disease (CGD) is an inborn error of immunity. NADPH oxidase is an enzyme complex that produces various reactive oxygen species, such as superoxide anions and hydrogen peroxide. Mycobacterial infections in CGD are commonly observed in countries with a high prevalence of these microorganisms, such as those receiving the BCG vaccination at birth or having a high prevalence of tuberculosis. Non-tuberculous mycobacteria (NTM) infections are rare in CGD. The patient also presented with hemophagocytic lymphohistiocytosis, which resolved with gammaglobulin and cyclosporine. Herein, we describe the first case of M. chimaera infection in a female patient with autosomal recessive CGD caused by a pathogenic variant in CYBA.
