The Effects of Treatment for Mycobacterium Avium Complex (MAC) on the Cells of HIV-Infected Patients
Completed
Conditions studied: Mycobacterium Avium-Intracellulare Infection, HIV Infections
In brief
To determine if treatment of MAC infection in HIV-1 infected persons is associated with the decreases in plasma levels of TNF-alpha. Infection with MAC is a poor prognostic indicator in persons with AIDS. Evidence suggests that this poor outcome is not simply a reflection of greater immune impairment in AIDS patients with MAC infection, but rather may be a direct or indirect consequence of infection with mycobacterium. Survival of AIDS patients with MAC is shorter than those without MAC. Studies show that treatment for MAC improves the survival of MAC infected patients to nearly the survival of AIDS patients without MAC. Treatment of MAC with clarithromycin containing regimens is associated with decreased symptoms and prolonged survival. There is evidence, however, that mycobacterial infection may enhance propagation of the human immunodeficiency virus through mechanisms that may involve enhanced expression of pro inflammatory cytokines. It is unclear to what extent cytokine abnormalities contribute to this symptom complex and to what extent treatment of MAC infection will reverse these cytokine abnormalities.

You may qualify if…
- Concurrent Medication:
- Allowed:
- Patients should have successfully completed therapy or be on stable therapy for any acute infectious processes other than MAC prior to study entry.
- Patients must have:
- Documented HIV infection.
- Either symptomatic MAC disease as defined by a history of clinical signs and symptoms, plus one blood culture positive for MAC or AFB obtained within the previous 90 days, OR asymptomatic MAC disease as defined by 2 blood cultures positive for MAC or AFB obtained within 90 days of entry.
- Signed parental consent for patients less than 18 years of age.
- Prior Medication:
- Allowed:
- Patients who have received presumptive or empiric antimycobacterial therapy prior to study entry may be enrolled if they have been treated for no more than 72 hours prior to study entry.
- Patients who have been receiving prophylaxis with azithromycin, clarithromycin and/or rifabutin may be enrolled.
- Patients should have successfully completed therapy or be on stable therapy for any acute infectious processes other than MAC prior to study entry.
- Required:
- Patients must be on a stable antiretroviral regimen (same drug or combination drugs; dose modifications allowed) for at least 4 weeks prior to study entry.
- NOTE:
- Patients will be requested NOT to modify or add new drugs to their stable ARV regimen for the duration of this study. Patients who absolutely require ARV changes at any time prior to week 8 will continue on study, however, their data will be analyzed separately.

- Cytokine inhibitors.
- Corticosteroids.
- Thalidomide.
- Pentoxifylline or any other immunomodulator.
- Any interleukin.
