Recognizing and managing mycobacterial diseases in clients with AIDS.
Mycobacterial diseases are common in people infected with human immunodeficiency virus. Mycobacterium tuberculosis (MTB) and Mycobacterium avium intracellulare (MAI), the specific pathogens most frequently involved, cause pulmonary tuberculosis and disseminated MAI infections. Pulmonary tuberculosis incidence was on the decline from 1950 to 1985, but since 1985 has been on the rise worldwide. Prior to the onset of AIDS, MAI infections were rare in humans. However, disseminated MAI seems to be associated with the terminal stage of AIDS. The symptomatology of MTB and MAI infections is similar, yet diagnosis and treatment vary. Pulmonary TB can be treated effectively with chemotherapy and isolation to prevent transmission. Because MAI infection is not a communicable disease, isolation is not necessary. Effective treatment for disseminated MAI remains under investigation; currently, a regimen of four to five drugs is recommended. There are however, significant side effects associated with this therapy. Because the number of AIDS patients is increasing, it is imperative for clinicians to understand the mycobacterial diseases and how best to manage them.
