Filter by:The Temprano trial is based on the following assumptions: - ART initiation at CD4 counts <800/mm3 could significantly reduce the probability of severe HIV-related morbidity or death in the medium term. - Tuberculosis and tuberculosis-related deaths are likely to represent a considerable proportion of morbidity and mortality among HIV-infected patients with high CD4 counts in sub-Saharan Africa. Therefore, 6-month Isoniazide Prophylaxis for Tuberculosis (IPT) and early ART could enhance each others efficacy.
Estimate of clinical and microbiological efficacy of Levofloxacin (Tavanic) in combine therapy of MDR TB. Estimate of safety of Levofloxacin (Tavanic) in combine therapy of MDR TB.
The purpose of this study is to determine whether the use of Nevirapine in HIV patients already treated against tuberculosis by Rifampicin is as efficient and as well tolerated as Efavirenz.
The purpose of this study is to evaluate the value of Quantiferon-TB Gold (QFT-G) assay in the screening for latent tuberculosis infection (LTBI) in rheumatologic patients due to start or on treatment with TNFα antagonists. The results of QFT-G will be compared to tuberculin skin testing (TST) and correlated to clinical and demographic data. The study hypothesis is that the inclusion of QTF-G in the screening strategy will allow a more accurate assessment of LTBI infection.
The randomized controlled trial is conducted among antiretroviral naive co-infected HIV and tuberculosis patients who receiving rifampicin-based antituberculous regimen fro at least 4 weeks butt not exceed 16 weeks before enrolment. All patients receive the same backbone regimen of stavudine (30 mg/40 mg twice daily)+ lamivudie 150 mg twice daily. They are randomized to receive nevirapine 400 mg/day twice daily vs efavirenz 600 mg/day at bed time. All patients are followed through 144 weeks after initiation of antiviral therapy. The primary objective are to compare the proportion of patient who achieve undetectable plasma HIV-1RNA<50 copies/ml at week 48. The previous reports demonstrated that the standard doses of both nevirapine and efavirenz coulde be used among co-infected HIV and tuberculosis patients who receiving rifampicin even though plasma levels are somewhat reduced by rifampicin. However, there have been not been a randomized control trial to compare these two regimens. Thus, this trial will provide the efficacy data between these two regimens.
A 48 week, randomized, open-label, two arm study to compare the efficacy, safety and tolerability of HAART containing nevirapine 400 mg/day versus nevirapine 600 mg/day in HIV-1 infected patients started at 2-6 weeks after initiating rifampicin containing antituberculosis therapy.
In this pilot study the pharmacokinetics and safety of the antiretroviral combination of co-formulated emtricitabine/tenofovir/efavirenz will be studied in HIV-positive patients with pulmonary tuberculosis (TB) who are concomitantly treated with a standard rifampin-containing tuberculostatic regimen. It is expected that this antiretroviral combination causes minimal drug interactions with the rifampin-containing anti-tuberculosis medication.
This study is designed as a cluster-randomized trial. The cluster unit is at the community level. Communities will be randomized to 1 of 2 study arms: DOTS+ACF or DOTS. Communities in the DOTS+ACF arm will receive door-to-door symptom screening of the entire population by health care workers between 2 and 4 times over a 9-month period. Those communities in the DOTS-arm will receive the current standard of care in those communities (PCF). All study communities will be receiving between 4 and 6 visits by community health workers annually as part of a program to assess and follow-up illnesses in each household. Households with ill residents will be visited more often. The intervention for this study is simply adding 3 to 5 simple questions to the current protocol. For subjects responding positively to these questions, results will be returned to the subject at their home and routine, standard of care follow-up diagnostic and treatment algorithms will be followed.
The purpose of this study is to document the efficacy and safety of intrapleural instillation of Activase vs Placebo in the management of complicated pleural effusions and empyemas
The dose of recombinant MVA used in the TB trials to date is relatively low compared with other trials using recombinant MVAs which have used up to 2.5 x 108pfu (A Hill, personal communication). Having demonstrated safety and immunogenicity of 5 x 107pfu of MVA85A, we now need to perform a dose optimization study, prior to commencing larger scale Phase II and III studies in South Africa. We will vaccinate 12 volunteers with a dose half a log lower than the dose we are currently using, i.e. 107pfu MVA85A, and 12 volunteers with a dose half a log higher, i.e. 108pfu.
