Filter by:The purpose of this study is to determine the bone mineral density in male and female patients with HIV infection according to age groups. This will enable a practical approach to screening for osteoporosis and the management and prevention of fragility fractures in people with HIV. In addition, all risk factors commonly associated with fragility fractures and osteoporosis are collected, as is HIV drug history. Hence, as secondary outcomes, the associations with reduced bone mineral density can be ascertained.
This study will evaluate the efficacy, safety, and tolerability of sofosbuvir (SOF; GS-7977) plus ribavirin (RBV) in adults with chronic genotypes 1, 2, and 3 HCV infection who are coinfected with HIV-1.
HIV-1 infection is characterized by progressive depletion of CD4+ T cells that eventually leads to clinically significant immunodeficiency. A chronic generalized immune activation is now being recognized to be the main driving force for T cell depletion, loss of anti-HIV-1 immunity and disease progression during chronic HIV-1 infection. However, it is still unknown whether reducing immune activation will restore CD4 T cell counts and leading to immune reconstitution in chronic HIV infection. Tripterygium Wilfordii Hook F (TwHF) has been demonstrated to decrease immune activation of the host, and can suppress inflammation in human diseases. Here, the investigators propose a hypothesis that TwHF can reduce immune over-activation which subsequently leads to the restoration of CD4 T-cell counts and immune reconstitution in HIV-infected immune non-responders.
The overall purpose of the study was to describe the real-life adherence, effectiveness and safety of the Kaletra Adherence Support Assistance (KASA) Program in human immunodeficiency virus (HIV)-positive patients who were receiving treatment with lopinavir / ritonavir (LPV/r; Kaletra®) in Canada.
This is a single-center, randomized, open-label, balanced, 3 way crossover study (3 periods) in healthy adult subjects. During each period, subjects will receive a single dose of GSK1265744 oral formulation in the fasted state and serial PK sampling for up to 168 hours (8 days) and safety assessments will be performed. Each period will be separated by a washout period of at least 14 days and a follow-up visit will occur 10 to 14 days after the last dose of study drug.
Although gains have been made in achieving the health-related Millennium Development Goals (MDG), much is still needed in countries affected by high levels of HIV/AIDS. Prevention of mother-to-child transmission (PMTCT) is a cornerstone strategy in reducing infant mortality from HIV. The study will employ a cluster randomized control trial (cRCT) with 26 health facilities randomized to two arms (intervention or control) to determine the effect of mobile phone technology on completion of key PMTCT milestones from antenatal to six weeks postpartum. The study will examine the acceptability, effectiveness, and cost of implementing a PMTCT-focused mHealth strategy among HIV-infected pregnant women, health workers, and male partners.
The study is designed to select a dose of GSK1265744 primarily on the basis of antiviral activity and tolerability in HIV-1 infected, antiretroviral naive subjects. This study consists of two parts: Induction Phase: Approximately 200 subjects will be randomized (50 subjects in each of the 4 treatment arms). The Induction Phase consists of a 24 week dose-ranging evaluation of GSK1265744 at blinded doses of 10 mg, 30 mg and 60 mg once-daily and a control arm of open-label efavirenz (EFV) 600 mg once daily. The background dual nucleoside reverse transcriptase inhibitor (NRTI) antiretroviral therapy (ART) for all arms will be either abacavir/lamivudine (ABC/3TC) or tenofovir/emtricitabine (TDF/FTC) as selected by the Investigator. Subjects randomized to a GSK1265744 containing arm, who successfully complete 24 weeks on study and demonstrate virologic suppression (defined as having a plasma HIV-1 ribonucleic acid [RNA] <50 copies per milliliter [c/mL] before Week 24, with no signs of virologic rebound) will become eligible for the Maintenance Phase of this study. Maintenance Phase: The background NRTIs will be discontinued and the subjects will continue their randomized dose of GSK1265744 in combination with rilpivirine (RPV) 25 mg once-daily for an additional 72 weeks. The Maintenance phase will evaluate the ability of this two drug ART regimen to maintain virologic suppression through Week 48, Week 72 and Week 96. Subjects randomized to the EFV arm will continue on their randomized regimen through Week 96. After completion of the maintenance phase, subjects could enroll in the Open-Label Phase to continue GSK1265744 + RPV treatment as long as they continue to derive clinical benefit and until it is locally approved and commercially available.
The overall aim of the BREATHER trial is to evaluate the role of Short-Cycle Therapy (SCT) in the management of HIV-infected young people who have responded well to antiretroviral therapy (ART) and to determine whether young people with chronic HIV infection undergoing Short-Cycle Therapy of five days on ART and two days off maintain the same level of viral load suppression as those on continuous therapy, over 48 weeks. To assess the advantages and disadvantages of the strategy, the incidence of toxicities, immunological control, resistance mutations, acceptability, quality of life and adherence to the randomised strategy will also be compared. Importantly, because of insufficient data on short-term viral load rebound after stopping ART in this population, the trial will incorporate an initial pilot phase in selected centres, to assess the safety of the SCT strategy by evaluating detailed HIV-1 RNA profiles of participants on the SCT strategy.
Highly active antiretroviral therapy (HAART) has considerably improved survival of HIV-infected patients. Opportunist diseases and cancers linked to immunodepression have largely regressed. Challenge is now the management of cardio-vascular diseases, nephrologic, neurologic, osteo-articular diseases, chronic hepatitis and cancer no linked to immunodepression. All this comorbidities are more reported in HIV-infected patients than in general non-HIV infected patients. Those are directly linked to the effect of chronic HIV-infection on ageing, metabolic effects of HAART, and way of life characterising this population. Chronic obstructive pulmonary disease (COPD) results from tobacco consumption. Bronchial chronic infection, immunity, and ageing are also involved in the physiopathology of COPD. This disease has never been evaluated in a large prospective cohort of HIV-infected patients whereas there is a known increase of tobacco consumption and pulmonary infection in this population regardless to the general population. Characterisation of COPD disease in HIV patients will allow us to make an hypothetic epidemiological link between HIV- HAART and COPD independently of tobacco consumption, and to study different physiopathologic hypothesis evocated in COPD genesis, like an accelerate pulmonary ageing.
This open-label study will evaluate the safety, pharmacokinetics and antiviral activity of a modified Invirase (saquinavir)/ritonavir regimen in treatment-naïve HIV-1 infected patients. Patients will receive Invirase 500 mg plus ritonavir 100 mg twice daily orally for the first week, followed by Invirase 1000 mg plus ritonavir 100 mg twice daily orally for the second week. The study treatment will be given in combination with two Nucleoside Reverse Transcriptase Inhibitors (NRTIs), in accordance with the current clinical HIV treatment guidelines. Anticipated time on study treatment is 14 days.
