title: Disseminated visceral infection with Mycobacterium fortuitum in a hemodialysis patient.
abstract: A 28-year-old patient with chronic renal failure on maintenance hemodialysis developed fever, granulomatous hepatitis, pulmonary infiltrates, sacroiliitis, and spondylitis which were unresponsive to conventional antituberculous treatment. Cultures of the sputum gave repeated growth of Mycobacterium fortuitum. This organism was resistant 'in vitro' to most antituberculous drugs and sensitive to some aminoglycosides and doxycycline. No mycobacteria were found in the water used for dialysis. The patient was successfully treated with amikacin and doxycycline. Nontuberculous mycobacterial infection should be considered in the differential diagnosis of febrile illnesses resembling tuberculosis in hemodialysis patients. Defective immune mechanisms could contribute to this complication. Since M. fortuitum is usually resistant to antituberculous drugs, precise identification and sensitivity testing are essential for optimal management.
