چکیده
BACKGROUND Nontuberculous mycobacteria (NTM) are found ubiquitously in the environment. Since exposure to NTM is universal, infection likely represents underlying host susceptibility factors. Anti-IFN-ɣ autoantibodies have been described previously in patients with NTM. Up to 88 % of patients with disseminated NTM or other opportunistic infections have high-titer anti-IFN-ɣ autoantibodies, compared with 2 % of patients with TB and healthy controls. FINDINGS We report a unique presentation of a patient with anti-IFN-ɣ autoantibodies with disseminated NTM infection who presents with panuveitis with multifocal retinitis and vasculitis. Treatment with systemic anti tubercular therapy resulted in complete clinical resolution with good visual recovery. CONCLUSIONS Patients with anti-IFN-ɣ autoantibodies present with a novel syndrome that links autoimmunity and immunodeficiency. This case emphasizes the importance of testing for anti-IFN-ɣ autoantibodies in patients with disseminated mycobacterial infection.

Anti-CD20 (rituximab) therapy for anti-IFN-γ autoantibody-associated nontuberculous mycobacterial infection.
Patients with anti-IFN-γ autoantibodies have impaired IFN-γ signaling, leading to severe disseminated infections with intracellular pathogens, especially nontuberculous mycobacteria. Disease may be severe and progressive, despite aggressive treatment. To address the underlying pathogenic IFN-γ autoantibodies we used the therapeutic monoclonal rituximab (anti-CD20) to target patient B cells. All...

We report a case of disseminated Mycobacterium genavense infection resulting from neutralizing anti-interferon-γ autoantibodies in the patient. We identified M. genavense targeting the hsp65 gene in an aspiration specimen of the lymph node. Adult-onset immunodeficiency caused by neutralizing anti-interferon-γ autoantibodies, in addition to HIV infection, can lead to disseminated nontuberculous ...

Adult patients with disseminated nontuberculous mycobacterial (dNTM) infections usually have severe immune system defects. Recently, several studies have shown that anti-IFN-γ autoantibodies may play an important role in the pathogenicity of dNTM infections. A considerable proportion of reported cases of anti-IFN-γ autoantibodies show either clinical or laboratory evidence of autoimmune disease...
