A Case of Mycobacterium gordonae Pulmonary Disease in a Patient with Ulcerative Colitis Treated with Infliximab / 대한내과학회지

ABSTRACT

Tumor necrosis factor-alpha (TNF-alpha) is a key component of the host defense against mycobacterial infection. Mycobacterium gordonae (M. gordonae) is one of the least virulent mycobacteria, and is generally considered non-pathogenic if detected from a clinical specimen. Here, we report a rare case of pulmonary M. gordonae infection in a patient with ulcerative colitis who had been treated with infliximab, a TNF-alpha antagonist. M. gordonae infection was treated successfully with clarithromycin, rifampin, and ethambutol. We believe this to be the first report of M. gordonae pulmonary disease associated with TNF-alpha antagonist treatment.
