Kekkaku. 1997 Oct;72(10):573-7. Unique Identifier : AIDSLINE
A 43 year-old Japanese male was admitted to our hospital because of
productive cough and fever. He was diagnosed as acquired
immunodeficiency syndrome (AIDS) in 1994. Laboratory findings were as
follows: WBC was 3200/microliter, CD4+ T lymphocyte count was
22/microliter. His chest X-ray film taken on admission showed
infiltration with small cavity lesion in middle left lung field.
Tuberculin skin reaction was negative. He was treated with isoniazid 0.4
g, rifampicin 0.45 g, and ethambutol 0.75 g each daily. Sputum smear was
positive for acid fast bacilli. The cultured isolates were identified as
Mycobacterium kansasii (M. kansasii) and Mycobacterium avium complex
(MAC). Urine smear was also positive for acid fast bacilli. The cultured
isolates were identified as M. kansasii. He was diagnosed as
disseminated M. kansasii infection and suspected MAC infection. About
one hundred days later, his chest X-ray film showed reticular shadow.
His clinical symptoms improved and the sputum smear and culture
converted to negative for acid fast bacilli. Based on these findings,
his MAC discharge was considered not as MAC infection, but MAC
colonization. He returned to the former hospital for AIDS treatment, and
he died in August 1996.
