Filter by:This observational study is supposed to assess (under conditions of clinical practice in daily routine) whether treatment with Viramune (nevirapine) in combination with Truvada (tenofovir and emtricitabine) will durably suppress viral load below the limit of detection or will maintain suppression of viral replication (HIV-RNA below limit of detection) achieved under previous anti-retroviral combination therapy after switch to combination treatment of Viramune (nevirapine) and Truvada (tenofovir and emtricitabine).
The purpose of this trial is to compare the effectiveness, safety and tolerability of TMC278 given at a dose of 25 mg once daily versus efavirenz (EFV) at a dose of 600 mg once daily, when combined with a background regimen containing 2 nucleoside/nucleotide reverse transcriptase inhibitors ( investigator choice of ABC/3TC, TDF/FTC or AZT/3TC) in HIV-1 infected patients who have not yet taken any anti-HIV drugs. The following evaluations will be done: antiviral activity, immunologic changes, and viral geno-/phenotype evolution, relationship of Pharmacokinetics (PK) and PK/Pharmacodynamics and Medical resource utilization and treatment adherence.
Monitor the safety and tolerability of efavirenz oral solution in combination with Antiretroviral Therapy for the treatment of patients age 3 to 16 years who have failed therapy or who are intolerant to their current therapy. This is an early phase trial and some specific protocol information is in progress and not publicly available at this time. (Full information is available to trial participants).
This study will evaluate patients who have achieved virologic suppression (< 400 copies/mL) on any dual protease inhibitor (PI) combination, to determine whether patients can substitute both PIs with the single boosted PI darunavir given 600/100 ritonavir (RTV) twice daily (BID) and maintain comparable virologic suppression (% < 50 c/mL) for 24 weeks.
A study comparing Indinavir plus Ritonavir plus 2 NRTIs vs. Nelfinavir 1250 plus two nucleoside reverse transcriptase inhibitors (NRTIs) in the treatment of HIV positive patients who have not responded to or are intolerant to a non-nucleoside reverse transcriptase inhibitor (NNRTI) containing treatment.
Background: The TB and HIV epidemics are closely linked in developing countries, where 450,000 children die from HIV annually. TB is a major cause of death in HIV-infected children and is reversing gains made in child survival. The traditional tuberculin skin test (TST) has limited diagnostic accuracy for detecting TB infection. Adult studies suggest that new blood-based diagnostic TB testing offers a quicker, more accurate way to diagnose TB infection. Such diagnostic testing may directly guide clinical management and preventive strategies in immune-suppressed HIV-infected children, who are at high risk of becoming TB diseased following infection. Data regarding the usefulness of these tests in children is currently limited. Objective(s) and Hypothesis(es): The investigators hypothesize that blood-based TB diagnostic testing can accurately identify children with TB infection. In a community with high rates of TB and HIV infection, the following specific aims will be investigated in HIV-infected and uninfected children: 1. assess the agreement between the TST and blood-based diagnostic testing, 2. compare the performance of the TST and blood-based diagnostic testing to a standardized history of TB exposure, 3. measure the impact of age, nutritional and immune status on children's response to blood-based testing, 4. describe factors that might modify children's response to testing over time, and 5) examine the effect of environmental exposures and previous vaccination on the TST, blood-based testing and other measures of immune responses to TB. Potential Impact: The benefits of an accurate, rapid diagnostic test of TB infection in children include 1) timely institution of treatment for TB infection to prevent severe disease and mortality, and 2) preclusion of over diagnosis and treatment. Treatment of childhood TB infection also prevents future contagious adult disease, thus decreasing community transmission. Blood-based diagnostic testing may also be able to identify children that are more likely to become ill following TB infection. Therefore, blood-based diagnostic testing has great potential to improve TB control and the health of HIV-infected and uninfected children, their households and communities.
A new approach to HIV prevention currently being studied includes the use of topical microbicides, substances that kill microbes. The purpose of this study is to determine the levels of tenofovir, a microbicide in gel form, in HIV uninfected pregnant women who are expecting to deliver by cesarean.
The purpose of this trial is to compare the effectiveness, safety and tolerability of TMC278 given at a dose of 25 mg once daily versus efavirenz (EFV) at a dose of 600 mg once daily, when combined with a fixed background regimen consisting of emtricitabine (FTC) + tenofovir disoproxil fumarate (TDF), in HIV-1 infected patients who have not yet taken any anti-HIV drugs. The following evaluations will be done: antiviral activity, immunologic changes, and viral geno-/phenotype evolution, relationship of Pharmacokinetics (PK) and PK/Pharmacodynamics, medical resource utilization and treatment adherence.
The purpose of this study is to investigate the possibility of an association between changes in neurocognitive function, as measured by a computerised test battery, and the use of two different highly active antiretroviral therapy (HAART) regimens in treatment naïve HIV-1 infected subjects commencing antiretroviral therapy.
The purpose of this study was to assess the effect of soluble fiber® (partially hydrolyzed guar gum) supplementation on hypertriglyceridemia and immune profile in HIV-positive individuals on HAART.
