Filter by:Tuberculosis is currently treated with a 6-month course regimen. During this time many patients might fail to adhere to treatment and default, increasing the risk of recurrent disease which might be multidrug resistant. A shorter duration of treatment is expected to provide improved patient compliance and at least equal or better clinical outcome. The aim of the trial is to evaluate the efficacy and safety of a gatifloxacin-containing regimen of four months duration for the treatment of pulmonary tuberculosis,
The use of fixed-dose combined (FDC) drugs in the treatment of tuberculosis by National Tuberculosis Programmes has been recommended by both the International Union Against Tuberculosis and Lung Disease (The Union) and the World Health Organisation. The advantages of FDC drugs include preventing the emergence of drug resistance due to monotherapy, reducing the risk of incorrect dosage, simplifying procurement and prescribing practices, aiding adherence and facilitating directly observed treatment. Recent bioavailability studies of four-drug FDC tablets have demonstrated satisfactory results. In this study, we are testing the efficacy of this compound, when given in the initial intensive phase of treatment of patients with newly diagnosed smear positive pulmonary tuberculosis. This will be followed by four months treatment with a two-drug FDC of rifampicin and isoniazid.
A scale-up of public sector antiretroviral treatment (ART) programmes may divert scarce resources from other priority primary care programmes like tuberculosis and childhood immunization. The purpose of this study is to compare the performance of tuberculosis (TB) and childhood immunization programmes in primary care facilities participating in the South African national antiretroviral treatment programme with those which have yet to be included in the ART programme.
Recent studies revealed that the ex vivo enzyme-linked immunospot (ELISPOT) assay for gamma interferon is a specific method for contact tracing of Mycobacterium tuberculosis infection. However, its use in endemic area and bacillus Calmette-Guérin (BCG)-vaccinated hosts has not been proved. We hypothesize that the TB-ELISPOT assay can be a rapid and accurate diagnostic tool for active tuberculosis in clinical suspects in Taiwan.
The purpose of this study is to determine whether the monoclonal protein in patients with tuberculosis and monoclonal gammopathy has anti-tuberculous activity, and whether genes coding their monoclonal proteins show characteristic mutations.
To investigate the size of PPD and TB specific ELISPOT among children between 3m/o and 15 y/o . Calculate the normal range of age specific PPD size in children who recieved BCG at new-born period.
The primary objective of this multi-center sub-study of USPHS Study 23: "Intensive Pharmacokinetic Study of Intermittent Rifabutin and Isoniazid with Daily Efavirenz in Combination with Two Nucleoside Analogs for Treatment of HIV and Tuberculosis Co-infections," is to compare the pharmacokinetics of rifabutin at 600 mg twice a week in combination with efavirenz 600 mg daily to the pharmacokinetics of rifabutin 300 mg twice a week without efavirenz. Secondary objectives are: (1) To describe pharmacokinetics of both rifabutin and efavirenz in combination regimen, (2) To evaluate the safety of concomitant efavirenz and rifabutin, (3) To assess the effect on absolute neutrophil count by changing rifabutin dose and adding efavirenz to the regimen, (4) To develop models of optimal sampling times for rifabutin dosed twice a week, (5) To describe the pharmacokinetics of isoniazid in combination with efavirenz daily with two NRTIs, (6) To compare the pharmacokinetics of isoniazid with and without efavirenz.
