Active clinical trials for "HIV Infections"

Access to highly active antiretroviral therapy can improve maternal health outcomes for the 4000 HIV- infected women who give birth daily and nearly eliminate transmission of HIV to their infants. However, system inefficiencies, particularly CD4 testing to determine treatment eligibility, are barriers. The project aims to study the effectiveness of a programmatic intervention at improving antenatal access to treatment.

In this study we will use a multi-modal imaging approach of MRS and fMRI to comprehensively assess the biological changes in the brain associated with EFV-based regimen (EFV/FTC/TDF), specifically alterations in the brain circuitry, function and local neurochemistry, and their correlation with neuropsychological function. In a cohort of HIV-infected patients who are clinically stable on the commonly use regimen of EFV/emtricitabine (FTC)/truvada (TDF) or Atripla, we propose to replace the EFV component with a new integrase inhibitor, elvitegravir (EVG) boosted with cobicistat (COBI), given as the EVG/COBI/FTC/TDF Single Tablet Regimen (STR) to evaluate the EFV-related neural alterations. This is a multidisciplinary study which involves a team of infectious disease experts in the field of HIV, neuroradiologists with expertise in fMRI and MRS techniques to study various central nervous system and psychiatric disorders and a psychiatrist with experience and expertise in research on abnormalities of affective and motivational processing in the context of neuropsychiatric disorders. We will utilize the established clinical research platform in the Infectious Disease outpatient clinical practice at the Brigham and Women's Hospital, where there is currently have many ongoing HIV-related studies and a large panel of HIV-infected patients motivated to be involved in clinically relevant research. We propose to use advanced neuroimaging to measure biologically changes in the brain associated with long-term EFV use with the following specific aims: Determine changes in neurometabolites measured by MRS in the brain associated with long-term EFV use Assess for alterations in neural activity correlated with affective symptoms associated with EFV vs STR use using fMRI, and their associations with changes in neurometabolites assessed by MRS, and with changes in cognition assessed by Trail Making and Digit Substitution Tests. Determine changes in emotion, cognition and sleep quality after switching from EFV to STR, and how they correlate with subject treatment preference. This clinical study will extend our current understanding of EFV neurotoxicity by further defining the nature of these biological changes. Further elucidation of the neurobiological underpinnings of EFV-induced CNS toxicity will have clinical relevance in improving the quality of life and drug adherence of HIV-infected patients on ART, especially among older patients or those with baseline neuropsychiatric disorders, whom at baseline are more vulnerable to neurocognitive decline from long-term HIV infection.

This research project will study whether the drug telmisartan administered in conjunction with antiretroviral therapy (ART) will help reduce nervous system infection with HIV. The investigators are studying the effect of this treatment in people who have contracted HIV infection within the past three weeks, and thus have a form of HIV called acute HIV infection. The investigators will measure biological markers of immune activation in the blood and cerebrospinal fluid to see if telmisartan may reduce the spread of HIV reservoirs in affected patients.

The study aims to develop and evaluate the efficacy and causal mechanisms of an interactive SMS intervention to optimize individual health and secondary HIV prevention benefits of ART in HIV-positive FSWs.

This randomized clinical trial is an adolescent focused implementation science study directed at improved social support and prevention of both HIV/STI's and subsequent unplanned pregnancies. The study population is pregnant adolescents who are attending antenatal care in Kampala, Uganda The acceptability and effectiveness of two enhanced peer lead, reproductive health promotion interventions compared to routine health care will be studied. The study participants will be individually randomized to one of three arms.

The purpose of this study was to examine the safety, efficacy, and pharmacokinetics of different dosages of deferiprone in subjects with or without HIV infection.

The purpose of this study is to assess the impact of a light meal, a standard meal, and a high fat meal on the PK of BMS-955176 MC tablet at a dose of 180 mg, relative to fasted conditions.

Early accurate diagnosis is one of the first crucial steps in care for infants born to HIV-infected mothers. Early initiation of antiretroviral therapy (ART) relies upon early diagnosis and results in significant reductions in infant morbidity and mortality. There is little information on evidence-based interventions that specifically target improved attendance of postpartum clinic visits and subsequent infant HIV testing in the context of prevention of mother-to-child transmission of HIV (PMTCT) programs. The investigators propose a randomized controlled trial to examine the effect of text messages sent to women enrolled in PMTCT programs on adherence to postpartum clinic visits and uptake of early infant diagnosis by DNA polymerase chain reaction (PCR). This study seeks to test the hypotheses that (a) text messages sent to women enrolled in PMTCT will improve their attendance at the postnatal clinic within the first 6-8 weeks after childbirth; and (b) text messages sent to women enrolled in PMTCT programs will increase uptake of DNA PCR HIV testing at 6-8 weeks among infants exposed to HIV. This study will evaluate a novel strategy to improve adherence to postnatal clinic visits and increase the uptake of infant HIV testing. If proven superior to standard care, the proposed intervention can be easily scaled-up and integrated into existing healthcare systems in resource-limited settings. Findings from this study will provide randomized trial evidence to inform HIV prevention program planners and implementers. This study will also provide further information on the feasibility of using mobile phone-based technology for public health interventions in resource-limited settings.

The purpose of this trial is to determine if door-to-door is more effective than community gathering in providing voluntary HIV counseling and testing (VCT) in communities in rural Lesotho. The voluntary HIV counseling and testing will be proposed as an integrated part of a package of proposed services. The package consists of: Blood-pressure measurement, blood-glucose measurement, Body-mass-index (adults), weight for height (children), catch-up vaccinations, deworming (children) Vitamin A (children & young women), family planning for eligible women, Tuberculosis screening and HIV counseling and testing.

The purpose of this study is to determine whether there is a drug interaction between GSK1349572 and the HIV protease inhibitors Tipranavir/Ritonavir (TPV/RTV).
