Filter by:This study will determine the differential cumulative mean number of isoniazid (INH) pills completed over 9 to 12 months for adolescents assigned to one of the following two groups: 1) peer adherence coaching, parent training, and self-esteem/life skills counseling; or 2) self-esteem/life skills counseling alone. The study will also estimate the costs and cost effectiveness of peer adherence coaching versus control procedures; this will be done from a provider and societal perspective.
In Cambodia the prevalence of both tuberculosis (TB) and Human Immunodeficiency Virus (HIV) infection is high. Data suggest that aggressive management of HIV infection, which includes Anti-Retroviral Therapy (HAART) during treatment of TB, decreases both morbidity and mortality. On the other hand, the use of HAART for patients with TB may cause severe complications due to drug-drug interactions, and occasionally a temporary exacerbation of symptoms. These reactions may be particularly severe when HAART is started soon after the start of TB treatment. The proposed study aims to determine the optimal time to initiate HAART in previously untreated HIV-infected adult patients with TB and low CD4 cell counts.
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.
This randomised controlled trial tests whether screening people registering with general practices cost-effectively increases the detection of tuberculosis. The study objectives are to: 1. recruit, and randomise with stratification, forty Hackney general practices to usual activity or screening for TB primarily during registration health checks (by practice nurses and GPs) and transfer-in visits for children (by health visitors) 2. implement a screening programme comprising education, resources and clinical support for intervention practices using proven behaviour change strategies 3. gather outcomes and costs 4. build research capacity within an ELENoR Primary Care Research Team and across a Primary Care Trust. The primary outcome is the proportion of TB cases identified in primary care. The study is powered to detect a 20% increase (from 55% to 75%) in the detection of new cases of TB in primary care with 80% power at the 5% significance level. Secondary outcomes are rates of prophylaxis for latent TB infection (LTBI), BCG immunisation, smear negative (early) TB and costs. Analyses will be by intention to treat.

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.
The purpose of this study is to assess lung immune responses in patients with active pulmonary tuberculosis (TB) and in healthy control persons who are exposed to Mycobacterium tuberculosis in households of patients with TB or who are unexposed.
This study will evaluate the lung's immune response to mycobacterium tuberculosis (Mtb) infection and will modulate that response with interferon-gamma.
The purpose of this study is to determine the efficacy of micronutrient supplementation among patients with active tuberculosis, half of who are co-infected with HIV-1
