About this study

To evaluate adherence and safety of three regimens of chemoprophylaxis for tuberculosis (TB) in HIV-infected patients with positive tuberculin skin test.

Read the detailed description

DESINGS: We performed a randomised, comparative and open clinical assay carried out in 316 HIV-infected patients. The patients were randomly assigned to one of three regimens, 108 to isoniazid for six months (6H), 103 to rifampin and isoniazid for three months (3RH), and 105 to pyrazinamide and rifampin for two months (2RZ).

RESULTS: The TB rates (cases per 100 persons/year) in the three treatment groups were 3.4 in 6H, 4.5 in 3RH and 1.9 in 2RZ. The relative risk for TB with 6H as compared with 2RZ was 1.76, and with 3RH, 2.34. Twenty-seven percent of the patients voluntarily abandoned chemoprophylaxis and 9.7% were withdrawn due to adverse side-effects. Seven patients were withdraw due to hepatotoxicity (5 in 6H, 2 in 3RH and 0 in 2RZ). No appreciable differences were found among the three regimens.

CONCLUSION: In our study the 2RZ regimen was as safe as the 6H and 3RH regimens. We have nor observed a higher incidence of hepatotoxicity in patients who received 2RZ.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing isoniazid, rifampin + isoniazid or rifampin + pyrazinamide in people with HIV Infections, run by Sociedad Andaluza de Enfermedades Infecciosas at 1 site in Spain.

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 4 inclusion and 7 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 11 Jan 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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.

What does the primary outcome measure?

Development of Tuberculosis. The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Jan 2007.
