[Mycobacterium tuberculosis infection complicated by talaromycosis in a patient with positive anti-interferon-γ autoantibodies: a case report].

High-titer antibodies to interferon-gamma (IFN-γ) are strongly correlated with infections caused by intracellular pathogens, particularly non-tuberculous mycobacteria and Talaromyces marneffei (TM). However, cases of concurrent infections with TM and Mycobacterium tuberculosis (MTB) in non-immunosuppressed patients are extremely rare. We presented a clinical case of a patient with anti-IFN-γ autoantibodies who developed an MTB infection complicated by Talaromyces marneffei, which subsequently led to secondary hemophagocytic syndrome. This report aimed to raise clinicians' awareness of this rare association to minimize the risk of misdiagnosis and overdiagnosis.
