Filter by:The objective of this study is to determine the long term safety and tolerability of an additional infusion of 10 billion VRX496 gene-modified CD4 T cells with a focus on evaluating additional therapeutic benefits with respect to viral load and CD4 counts.
There are increasing numbers of HIV-infected patients in sub-Saharan Africa receiving antiretroviral drugs and/or rifampicin based antituberculous therapy. HIV infected patients are at an increased risk of contracting malaria. Increasing resistance to anti-malarials such as chloroquine, amodiaquine, fansidar, sulphadoxine-pyrimethamine in East and West Africa has led the WHO to recommend artemether-lumefantrine (Coartem®- Novartis) as first line therapy for malaria for adults and children. As early as 2004, fourteen countries in sub-Saharan Africa had adopted this guideline as national policy. There are no data on the interaction between Coartem® and any of the antiretroviral agents. Both components of Coartem® are substrates for the 3A4 isoform of cytochrome P450. Despite the lack of data, antiretroviral drugs and/or antituberculous drugs in addition to Coartem® are of necessity co-prescribed daily in the African setting. Nevirapine, efavirenz and rifampicin are known inducers of cytochrome P450 3A4. A technical consultation convened by WHO in June, 2004 concluded that additional research on interactions between antiretroviral and antimalarial drugs is urgently needed. We propose to perform a suite of pharmacokinetic studies to evaluate these interactions in HIV infected Ugandan patients. The aim of these studies is to evaluate the pharmacokinetic interaction between Coartem® and commonly co-prescribed inducers of 3A4 i.e. nevirapine, efavirenz and rifampicin. 1. Comparison of steady state pharmacokinetics of Coartem® in HIV-infected patients prior to commencement of nevirapine and at nevirapine steady state 2. Comparison of steady state pharmacokinetics of Coartem® in HIV-infected patients prior to commencement of efavirenz and at efavirenz steady state 3. Comparison of steady state pharmacokinetics of Coartem® in Ugandan patients at rifampicin steady state and without rifampicin
The investigators are proposing that energy specific electromagnetic radiation of the central nervous system, the viscera and the endocrine system has the potential to enhance the immune system; thereby enhancing the production of killer cells to fight and destroy the human immunodeficiency virus.
The purpose of this study is to asses whether probiotics Lactobacillus rhamnosus (GR-1) and reuteri (RC-14) are able to prevent diarrhea, delay the decline of the immune system and prevent and/or cure bacterial vaginosis among HIV patients.
The use of a Bioject 2000 needle free injection device (NFID) and a compressed immunization schedule will be safely tolerated and will augment the immunogenicity of the HIV-1 CTL epitope DNA vaccine (EP1090) in HIV-1 infected individuals receiving potent combination antiretroviral therapy (ART) and who have undetectable levels of viral replication in plasma.
This study aims at correlating TNF-α, INF-γ, IL-2, IL-4, IL-10 and TGF-β values as dosed by ELISA and mRNA expression by real-time PCR with histopathological hepatic biopsy findings in individuals with HIV/HCV coinfection. This population will be divided into three groups (G1: with no HAART; G2: with detected HIV viral load (HIV VL); G3: with undetected HIV VL), which will be then compared to two control groups with monoinfection by HIV or by HCV, in addition to a third control group comprising normal blood donors.
To evaluate clinical and immunological outcome of children treated with HAART.
The optimal time to initiate antiretroviral therapy (ART) in HIV-associated tuberculous meningitis (TBM) unknown. There are concerns that immediate ART may worsen rather than improve outcome, because drug interactiond and toxicities or development of an intracerebral immune reconstitution inflammatory syndrome (IRIS). Conversely, delaying ART may result in increased HIV-related deaths. To answer this question, we are conducting a randomised, double-blind placebo-controlled trial comparing immediate and deferred ART in HIV-infected patients presenting with TBM, to assess effect on survival.
Title: Randomized clinical trial to assess the efficacy of short course intermittent regimens for the treatment of HIV-associated tuberculosis Phase: Phase III trial Population: 300 HIV positive patients with tuberculosis. Number of Sites:Four 1. Tuberculosis Research Centre, Chennai 2. Government General Hospital, Chennai 3. Government Hospital of Thoracic Medicine, Tambaram 4. Government Rajaji Hospital, Madurai Study Duration:36 months Study Objective:To study the efficacy of the standard RNTCP Category I regimen (2EHRZ3 / 4RH3) the control arm vs. an extended continuation phase regimen 2EHRZ3 / 7 RH3 in the treatment of pulmonary and extrapulmonary TB in the HIV positive patients. 2. To study the relationship between stage of HIV disease and response to anti-TB treatment. 3. To study recurrences and their nature (relapse/re-infection) in detail by using RFLP analysis. Study Design:It is a two armed prospective randomized open label controlled clinical trial with stratified random allocation based on CD4 count and sputum smear grade. All enrolled patients will be treated according to the RNTCP guidelines during the intensive phase. In the continuation phase, Cat I patients will be stratified by CD4 counts and by smear grade, and randomly allocated either to the standard RNTCP regimen, or to an alternative extended regimen (2EHRZ3/4RH3 or 2EHRZ3/7RH3).
Protocol Summary Title: Evaluation of safety and efficacy of two different once daily anti-retroviral treatment regimens along with anti-tuberculosis treatment in patients with HIV-1 and tuberculosis - Randomized Controlled Clinical Trial Phase: Phase III trial Population: 180 HIV-1 positive patients with tuberculosis Number of Sites: Four. 1. Tuberculosis Research Centre, Chennai 2. Government Medical College, Vellore 3. Government Hospital of Thoracic Medicine, Tambaram 4. Government Rajaji Hospital, Madurai Study Duration: 26 months including 24 months of ART. Study Objectives: Primary Objective To compare the efficacy and safety of two different once-daily anti-retroviral treatment regimens (along with standard anti-tuberculosis treatment) in patients with HIV-1 and tuberculosis, by using virologic end points. Secondary Objective To compare the efficacy of antiretroviral treatment given under partial supervision with unsupervised treatment (once a month supply).
