Active clinical trials for "Tuberculosis"

This study is designed to determine whether 6 months of anti-HIV drugs given along with tuberculosis treatment will delay the onset of AIDS in HIV infected African patients.

This was a clinical trial in HIV infected patients with tuberculosis. The study assessed whether the addition of prednisolone, a type of steroid medication, to the standard treatment for tuberculosis improved immune and viral outcomes in the patients. The study demonstrated that prednisolone increased the CD4 cell count as was hoped, but the beneficial effect was short-lived and was gone within 4 months of stopping therapy. Therefore, the use of prednisolone for tuberculosis in HIV infected patients is not recommended at this time.

PER 5/30/95 AMENDMENT: To compare the combined rate of failure during therapy and relapse after therapy between two durations of intermittent therapy (6 versus 9 months) for the treatment of pulmonary tuberculosis (TB) in HIV-infected patients. To compare toxicity, survival, and development of resistance in these two regimens. ORIGINAL: To compare the efficacy and safety of induction and continuation therapies for the treatment of pulmonary TB in HIV-infected patients who are either from areas with known high rates of resistance to one or more anti-TB drugs or from areas where TB is expected to be susceptible to commonly used anti-TB drugs. PER 5/30/95 AMENDMENT: In HIV-negative patients, intermittent anti-TB therapy has been shown to be as effective as daily therapy, but the optimal duration of therapy in HIV-infected patients has not been established. ORIGINAL: In some areas of the country, resistance to one or more of the drugs commonly used to treat TB has emerged. Thus, the need to test regimens containing a new drug exists. Furthermore, the optimal duration of anti-TB therapy for HIV-infected patients with TB needs to be determined.

CF patients are at risk for hepatic disease. Vaccination is recommended to all CF patients according to European consensus. The aim of the study is to vaccinate as many patients as possible and to follow up whether immunization has been complete.

Whether radical debridement is necessary for the treatment of thoracic and lumbar tuberculosis is still questionable. The objective of this prospective randomized study was to compare the outcomes of radical debridement versus no debridement under different surgical procedures for the treatment of thoracic and lumbar tuberculosis.

Evaluate the possibility of using an IGRA (Interferon-γ Release Assay) test for monitoring the response to anti-tuberculosis therapy by studying the correlation between the variation in the Interferon-gamma (IFN-γ) response to the QFT-Plus test in the two tubes containing antigens and the gold standard for monitoring TB therapy (culture conversion) in patients with slide positive/culture positive and slide negative/culture positive PTB. Evaluate the level of agreement between the results of the new QFT Access test and the results of the QFT plus and culture in patients diagnosed with active tuberculosis. To evaluate the level of agreement between QFT Access test results and QFT Plus results in healthy controls and contacts.

Evidence of the clinical diagnostic accuracy and operational characteristics of the Bioneer IRONqPCR ™ RFIA Kit is needed to comprehensively evaluate Bioneer RFIA validity and inform global and national policy decision-making. The rapid diagnosis and appropriate treatment of M/XDR-TB is essential to prevent significant morbidity, mortality and further transmission of disease. The FQ are key components of the new bedaquiline-containing 6-9 month regimen, and so it is necessary to rule-out resistance to these compounds prior to treating patients with the shorter regimen. Currently there are no WHO endorsed tests that can identify resistance to both first and second-line drugs in one reaction.

The trial will evaluate the extended bactericidal activity of 14 consecutive days of oral administration of TMC207 alone, TMC207 with pyrazinamide, TMC207 with PA-824, PA-824 with pyrazinamide and PA-824 with moxifloxacin and pyrazinamide, as determined by the rate of change of log CFU in sputum over the time period Day 0-14 in participants with smear positive pulmonary tuberculosis (TB). A control group will receive standard treatment.

This is a randomized, open-label study comparing three existing treatment strategies of ART initiation in HIV/TB co-infected patients: Group 1: early initiation of ART with TB treatment, Group 2: initiation of ART upon completion of the intensive phase of TB treatment, Group 3: initiation of ART upon completion of the continuation phase of TB treatment Approximately 700 men and women ≥ 18 years of age with documented HIV infection and smear-positive pulmonary TB patients will be enrolled. Eligible TB/HIV co-infected patients will be offered antiretroviral therapy (ART), starting at one of the three time points listed above through the CAPRISA AIDS treatment programme which includes extensive counselling and adherence support. The study participants will be followed for 18 months to assess the primary study endpoint of the optimal time to start antiretroviral therapy (ART) in patients on tuberculosis (TB) treatment by comparing clinical status (CD4+ cell count, viral load, opportunistic infections.

The purpose of this study is to determine if a relationship exists between the level of antituberculosis drugs (isoniazid, rifampin, ethambutol, and pyrazinamide) in the blood and the outcome of HIV-positive patients with tuberculosis. This study also evaluates how these drugs are absorbed and metabolized in the body.
