Mendelian susceptibility to mycobacterial disease: genetic, immunological, and clinical features of inborn errors of IFN-γ immunity

Mendelian susceptibility to mycobacterial disease (MSMD) is a rare condition characterized by predisposition to clinical disease caused by weakly virulent mycobacteria, such as BCG vaccines and environmental mycobacteria, in otherwise healthy individuals ...

Mendelian susceptibility to mycobacterial diseases: Specific defects

Mendelian susceptibility to mycobacterial diseases (MSMD, MIM #209950) is caused by genetic defects in the mononuclear phagocyte/T helper cell type 1 (Th1) pathway. Patients with MSMD have increased susceptibility to systemic infections with weakly v

Cheng-Lung Ku and colleagues report that anti-interferon (IFN)-[gamma] autoantibodies in patients with disseminated mycobacterial infections recognize the C-terminus of IFN-[gamma], and suggest that autoantibodies may arise by molecular mimicry. The authors propose a therapeutic strategy to treat pa...

People with acquired interferon-gamma deficiency/dysfunction can manifest with disseminated mycobacterial infections, including Tuberculosis. Even with appropriate anti-tuberculous antibiotics, they may not be able to clear the infection.

Rituximab as Successful Adjunct Treatment in a Patient With Disseminated Nontuberculous Mycobacterial Infection Due to Acquired Anti–Interferon-γ Autoantibody

An acquired immune deficiency due to interferon gamma (IFN-γ) autoantibodies was diagnosed in a 78-year-old Japanese man with treatment-refractory disseminated nontuberculous mycobacterial infection. In addition to standard antimycobacterial therapy, ...
