exercise and physical activity can have an anti-inflammatory effect, while there is evidence that a sedentary lifestyle could be the basis for the development of systemic inflammation and increased cardiovascular risk. The primary objective is to assess whether regular physical activity is able to induce a decrease in systemic immune-activation in HIV positive patients.
This study evaluates the impact of Zimbabwe's program for the prevention of mother-to-child HIV transmission (PMTCT) on vertical transmission of HIV infection and HIV-free survival among infants exposed to HIV. The study will test the hypothesis that the accelerated PMTCT program in Zimbabwe will result in fewer new HIV infections in infants and will increase infant survival.
The investigators propose to utilize quantitative and qualitative methodology to better understand the impact of multiple drug use (polypharmacy) on medication adherence as well as the driving forces behind differential adherence in people living with HIV (PLWH) with comorbidities. Since the clinical relevance of differential adherence to antiretroviral therapy (ART) medication has already been demonstrated and associated with virologic failure and a more rapid progression to AIDS and death, it is imperative to understand the driving forces behind differential adherence (selective drug taking) and its impact on treatment outcomes in PLWH with comorbidities. Moreover, the use of technology to improve medication adherence is receiving much attention, and there are several smartphone applications that send medication reminders and generate personalized text messages to further motivate users. This type of technology could be particularly beneficial to patients who are managing multiple medications for multiple conditions. To this end, the investigators propose to use the medication adherence smartphone-based application, 'Technology for Engagement And Management of Health (TEAMH) to track both medication adherence and medication side effects in real-time among PLWH with comorbidities. TEAMH is an interactive health care information technology system that is not only patient-centered in that it encourages patient engagement in health care self-management, but also offers significant cost savings by directly connecting patients with their health care providers allowing providers to quickly address any health issue that may arise, thus potentially avoiding costly hospitalizations later on.
The purpose of this study is to evaluate the safety, tolerability, and serum concentrations of a human monoclonal antibody, VRC-HIVMAB075-00-AB (VRC07-523LS), administered in multiple doses, routes, and dosing schedules to healthy, HIV-uninfected adults.
The purpose of this study is to evaluate the pharmacokinetics, feasibility, acceptability, and safety of a fixed-dose combination of emtricitabine and tenofovir disoproxil fumarate (FTC/TDF) as oral daily pre-exposure prophylaxis (PrEP) to prevent HIV during pregnancy and postpartum in adolescents and young women and their infants.
Maternal infections affect the basal immune status of neonates. One of the possible mechanism is the fetomaternal microchimerism, in which some cells and active substances are exchanged bi-directionally between maternal and fetal circulation through placenta. Even in the absence of a direct (vertical) transmission of pathogens to fetuses, certain infections make the neonates more prone to allergies and some adverse events of early vaccinations. We postulate that the basal immune status of neonates born to HIV and LTBI infected mothers is primed by gestational exposure to immunological active molecules, which could results in an altered response to early BCG vaccination. Transcripts expression identified by RNA sequencing are compared between sets of mother-child and their respective umbilical cord blood, and between groups of infected and non-infected pairs.
This study will evaluate the effects of tamoxifen exposure in combination with vorinostat on viral reactivation among HIV-1 infected post-menopausal women with virologic suppression on antiretroviral therapy (ART), when compared to vorinostat alone.
The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of an HIV vaccine (gp145 C.6980) with aluminum hydroxide adjuvant in healthy, HIV-1-uninfected adults in the United States.
Efficacy of etravirin + raltegravir dual therapy was showed in the ANRS 153 ETRAL protocol, in HIV-1 seropositive patients. The use of these two drugs avoids the use of nucleoside reverse transcriptase inhibitors and protease inhibitors, with a real benefit in older patients, who increasingly present contraindications to these drugs' families. The disadvantage of this strategy is twice daily (BID). Pharmacological data suggest that etravirine once a day and raltegravir once a day may provide the same virological efficacy. The objective of our study is to evaluate the ability of ETRAL QD (etravirine 400 mg x1/day + raltegravir 800 mg x1/day) to maintain virologic success at week 48 (W48), after switch, in HIV-patients under ETRAL BID (etravirine 200 mg x2/day + raltegravir 400 mg x2/day). Virological success is defined as absence of virological failure, and virological failure is defined as two consecutive plasma viral loads >50 cp/ml over 2-4 weeks, or one plasma viral load >400 cp/ml. This study will be a multicentric data collection. Data will be collected at W0 (patient characteristics, plasma viral load) and then at W4, W12, W24 and W48 (plasma viral load). If stopping strategy, the reason for stopping will be documented. 125 patients will be included in the six participating centers. Data will be centralized at Pitié-Salpêtrière hospital, Paris, with an anonymized e-CRF.
In a multi-center study 200 patients co-infected with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) will be treated with a fixed-dose combination pill combined of 400 mg sofosbuvir and 30, 60, or 90 mg of daclatasvir - depending on the particular antiretroviral treatment (ART) being used by the patient. The treatment duration will be 12 weeks for subjects without cirrhosis and 24 weeks for those with cirrhosis.
