Cerebral mycobacterium avium infection in an HIV-infected patient following immune reconstitution and cessation of therapy for disseminated mycobacterium avium complex infection.
Reported here is a case of cerebral Mycobacterium avium complex infection that occurred in an HIV-infected patient, who had been treated for disseminated infection and had discontinued clarithromycin and ethambutol following a significant rise in his CD4+ T-cell count after starting highly active antiretroviral therapy. He responded well to excision of the lesion and reinstitution of multidrug therapy. Caution should be exercised when considering ceasing maintenance therapy for disseminated Mycobacterium avium complex infection in HIV-infected patients who demonstrate an apparently good immunologic response to highly active antiretroviral therapy, as this response may not necessarily restore protective immunity against all opportunistic pathogens.
