The need for a standardized treatment protocol for multidrug resistant tuberculosis (MDR-TB) in resource-limited countries is being increasingly recognized. This single center, double blind, randomized controlled trial was designed to compare the time required for sputum culture conversion and extent of radiological improvement in cases of MDR pulmonary tuberculosis when isoniazid was included (both at a regular dose and at a high dose) as an adjuvant to the standardized second line of treatment. The study was designed to test the hypothesis that inclusion of high-dose isoniazid will enhance the effectiveness of the second line of treatment in cases of MDR-TB without significantly increasing the toxicity.
Primary Objective: 1. To evaluate the performance of the new T-SPOT.TB test and the conventional TST for screening of Latent Tuberculosis infections in patients with cancer and those undergoing Hematopoietic Stem Cell Transplant. Secondary Objectives: 1. To examine the factors associated with positive response to T-SPOT.TB and the TST (tuberculin skin test) in patients with anergy. 2. To determine the impact of immunosuppressive and antineoplastic therapy on the screening performance of T-SPOT.TB and the TST in cancer patients.
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 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.
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
