Clinical features and successful recovery from disseminated nocardiosis after BMT.

Nocardiosis has rarely been described after BMT. When the doses of immunosuppressive therapy were tapered, a 46-year-old BMT recipient developed chronic graft-versus-host disease (GVHD) and immunosuppressive drugs were increased. Sixteen days later the patient developed nocardiosis diagnosed by lung biopsy. Trimethoprim/sulfamethoxazole (TMP/SMZ) was initiated but the doses were reduced because of rising creatinine levels. Skin and cerebral dissemination of nocardiosis was observed and TMP/SMZ doses were increased. After 4 months, the brain lesion was unaltered despite resolution of pulmonary lesions. Clinical improvement was observed after drainage of the brain abscess. [ABSTRACT FROM AUTHOR]
