About this study

Official title: Effects of Treatment for MAC Infection on Cytokine Expression in HIV-Infected Persons.

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.

Studies show that treatment for MAC improves the survival of MAC infected patients to nearly the survival of AIDS patients without MAC.

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.

All patients diagnosed with MAC and who will initiate at least a 2 drug clarithromycin containing MAC treatment regimen will be eligible for participation. Blood and urine will be obtained from each patient at the following timepoints: Pre-Entry (within 7 days prior to study entry), week 4, and week 8. Sites will process and ship specific samples to Case Western Reserve University (CWRU). Various assays and analyses will be performed by CWRU. NOTE: Patients will receive no treatment on this study, however, all patients must be receiving at least a 2 drug clarithromycin containing treatment regimen for MAC either as part of participation in other studies or as prescribed by the subject's health care provider.

Questions about this trial

What is this clinical trial studying?

An observational study of Mycobacterium Avium-Intracellulare Infection and HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 11 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00000860, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2005.
