Abstrakt: We evaluated a patient with disseminated Mycobacterium tuberculosis and Mycobacterium chelonae infection, of which he died. He also developed autoimmune (type I) diabetes and primary hypothyroidism. His serum contained a high titer of immunoglobulin G autoantibody to interferon-γ (IFN-γ) capable of blocking in vitro responses to this cytokine by peripheral blood mononuclear cells from normal donors. These results suggest that autoantibodies to IFN-γ can induce susceptibility to disseminated mycobacterial infection, which may be refractory to chemotherapy. [ABSTRACT FROM AUTHOR]
