Active clinical trials for "Acquired Immunodeficiency Syndrome"

This study aimed to investigate the effect of an exercise session with weights associated with glutamine dipeptide (GLD) supplementation on cognitive function of people living with HIV/ AIDS. The sample consisted of 10 HIV+ women, who used the Antiretroviral Therapy Highly Active. The participants were randomized in a double-blind procedure to receive seven days of supplementation GLD or placebo (PLA). At the end of this first period, the participants held a workout with weights with cognitive assessments before and immediately after the session. To evaluate oxidative stress markers blood samples were collected before and 1 hour and 2 hours after the session.Then the participants rested for 7 days for the initial stocks of glutamine return to baseline levels (washout). Following was realized the crossing of the groups, so those who had received the GLD in the first week spent extra for 7 days with PLA and vice versa, and then they repeated evaluations and exercise session. The exercise session consisted of seven resistance exercises involving different muscle groups, with three sets of 8-12 repetitions with an interval of 90 seconds between sets and 120 seconds between the exercises. Stroop test was used to cognitive assessments, which aims to assess selective attention and inhibitory control over the color of conflict and word, and the N-back test, responsible for evaluating the central executive component of working memory by stimuli visual. Oxidative stress markers (TBARS, FOX, GSH, GSSG, AOPP) were analyzed in plasma samples.

The study harnessed the multidisciplinary expertise of our research team to develop a brief, computer-based, alcohol reduction intervention tailored for HIV/HCV co-infected women and evaluate its efficacy. The intervention, if effective, may be an efficient and cost-effective alcohol reduction strategy, that is scalable and can be readily disseminated and integrated in clinical care at other AIDS Centres in Russia to enhance women's health and reduce HIV/HCV transmission risk.

The conventional way to control HIV infection is the usage of a drug cocktail capable of suppressing the viral replication cycle, commonly known as antiretroviral therapy (ART). Despite effective ART it is not possible to eradicate HIV. The virus hides in particular cells to form the latent HIV-reservoir.[1-9] Studies that emphasise on revealing hidden reservoirs would aid in designing novel therapeutic strategies for controlling HIV infection. Molecular imaging by SPECT/CT has the potential to reveal hidden reservoirs of HIV virus that are not eliminated by currently used drugs capable of suppressing and thereby controlling the viral replication cycle in HIV infected patients. New approaches, necessary to prevent and treat HIV-1 infection, are gradually emerging. A new generation of highly potent broadly neutralizing antibodies (bN/Abs) may represent a promising approach to combating HIV-1 infection.[10] The broadly neutralizing antibody 3BNC117 antibody that can mimic human CD4 binding targeted against the HIV gp120 envelope protein has been tested in various clinical trials.[11-14] It has found to be safe and effective in reducing viraemia and to improve host humoral responses in HIV-1 infected individuals, and to have effect on viral rebound in patients who are kept off antiretroviral treatment briefly for experimental purpose. Imaging of simian immunodeficiency virus (SIV) infection by PET/CT has been successfully performed in nonhuman primates with a 64Cu-labeled SIV gp120-specific antibody called 7D3.[15] This study aims to use a similar approach in human with the 3BNC117 antibody. The 3BNC117 antibody has been successfully radiolabeled with iodine 123. The half-life of this radioisotope is appropriate for antibody imaging in nuclear medicine. Radiolabeled 123I 3BNC117 was shown to keep a good immunoreactivity for gp120. By using state of the art SPECT scanner a semi-quantitative image will be obtained. In addition, the absence of any chelator and the well known use of iodine-123 in clinic make it suitable for human intervention. No HIV imaging in human has been achieved yet, which is however fundamental to understand some key steps in the pathogenesis of HIV-induced immunodeficiency. This research opens promising opportunities for drug and vaccine development. Indeed, identification of virus reservoirs in treated patients would facilitate the development of strategies for eradicating these reservoirs or for extending latency period.

Oral pre-exposure prophylaxis (PrEP) has been proven effective in reducing HIV infection in high-risk men who have sex with men, heterosexually active women and men, and injecting drug users. Despite its 2012 approval by the FDA and the development of Centers for Disease Control and Prevention (CDC) clinical guidelines, PrEP uptake has been limited. Significant impediments to PrEP implementation include: system barriers (lack of a medical "home" and of models for implementing PrEP); provider barriers (difficulty identifying those likely to benefit from PrEP, inexperience with PrEP, and concerns about adherence and risk compensation); and user barriers (lack of awareness of PrEP, inability to access providers comfortable with prescribing PrEP, and concerns about stigma and side effects). Cost is not a barrier in New York State, where PrEP is covered by many insurance plans, including Medicaid. Primary Care for PrEP (PC4PrEP) is a structural, multilevel intervention that will integrate PrEP into primary care practices that care for underserved communities in the Bronx, NY, an epicenter of continuing HIV infection in the US. PC4PrEP will develop an organizational protocol for prescribing PrEP in primary care; identify high-risk individuals in primary care clinics and community HIV testing sites using a new PrEP Eligibility Tool; link them to primary care providers (PCPs) who can provide PrEP; and counsel potential users about PrEP both before they receive a prescription (to enhance receptivity), and after they initiate PrEP (to enhance adherence). In the course of this study, investigator(s) will (1) develop and pilot PC4PrEP; (2) implement and evaluate it in "real-world" settings (Federally Qualified Health Centers; FQHCs) on objective outcomes as well as provider and patient reports; and (3) present a new model, the PrEP Cascade that - as with the HIV Care Cascade for HIV+ populations - may be used to evaluate the impact of PrEP programs in the US and other countries. PC4PrEP is consistent with CDC and New York State Department of Health (NYSDOH) Guidelines and the Affordable Care Act in integrating PrEP into primary care practices and is responsive to recent 2014 NYSDOH recommendations which now position PrEP as a first-line intervention for MSM and transgender women who engage in ongoing anal sex without condoms, HIV- partners in sero-discordant relationships, and high-risk heterosexual women in high seroprevalence areas.There are two Specific Aims: (1) Finalize the PC4PrEP intervention and, in a clinic-randomized Phase 2 futility trial, assess whether it shows promise for increasing PrEP prescription rates in the Bronx, NY; and (2) Identify strengths and limitations of PC4PrEP in two ways: (a) through a mixed-methods process evaluation PrEP-eligible patients and PCPs, counselors and navigators; and (b) by identifying "fall-off" at each step of the PrEP Cascade.

This is a Phase 1/2a open label study to evaluate the safety, tolerability, pharmacokinetics and anti-viral activity of PGT121, VRC07-523LS and PGDM1400 for HIV prevention and therapy.

The purpose of this study is to evaluate the feasibility, acceptability, clinical outcomes, affordability, and scalability of offering early antiretroviral treatment to all HIV-positive individuals in Swaziland's government-managed health system.

This is a randomized controlled trial of a new behavioral intervention designed to improve engagement in HIV care for couples. Investigators will compare the HIV viral load outcomes of couples randomized to a couples-based adherence intervention (DuoPACT) or to an individual adherence intervention (LifeSteps).

Ebola and HIV are found predominately in the same regions of the world and countries in sub-Saharan Africa are most affected by both diseases. For Ebola, no approved therapies exist. However, new investigational drugs are being evaluated to understand if they are effective against the Ebola virus. Remdesivir is an anti-Ebola investigational drug for the treatment of Ebola. Little is known about how the blood levels of remdesivir relate to how effective it is in patients with HIV taking antiretroviral therapy. This study will explore how commonly utilized ART (tenofovir/lamivudine and atazanavir/ritonavir) affect the drug levels of remdesivir.

This CDC-funded study sought to evaluate the effect of an adapted Community Score Card Approach on maternal retention in ART, maternal retention across the PMTCT service cascade, and the uptake of early infant diagnosis services in Malawi. The study also estimated the cost of the implementation of the Community Score Card Approach.

This study aims to improve maternal and child health (MCH) outcomes by implementing and evaluating a multidisciplinary "Integrated Management Team to Improve Maternal-Child Outcomes (IMPROVE)" intervention to increase MCH, antiretroviral therapy (ART), and HIV services uptake and retention in Lesotho. The proposed intervention will focus efforts to improve the effectiveness of existing village health workers (VHW) and HIV support organizations (Lesotho Network of AIDS Service Organizations [LENASO] and Mothers2Mothers [M2M]) based at the facility and coordination between the facility and community. The IMPROVE intervention includes: (1) Multidisciplinary integrated management teams to coordinate patient-focused and outcome-oriented PMTCT and MCH services; (2) Enhanced Positive Health, Dignity, and Prevention (PHDP)-focused counseling and skills-building training and job aids; and (3) Increased early community-based counseling and support for first (antenatal care clinic) ANC attendees with particular attention to HIV-positive women to minimize loss to follow-up. The study will be a cluster randomized design with facilities randomized to receive the IMPROVE intervention or routine services offering the national standard of care. A cohort of HIV-positive and HIV-negative pregnant women will be enrolled and prospectively followed every three months through pregnancy and until the participant's child reaches 24 months of age. The primary HIV objectives will be to evaluate the effect of the intervention on retention in HIV care, viral suppression, adherence to ART in HIV-positive women, and HIV retesting in HIV-negative women. The investigators will also assess the effect of the IMPROVE intervention on general MCH indices including antenatal care (ANC) attendance, facility delivery, family planning, and immunization coverage. Secondary objectives include evaluation of adherence self-efficacy (HIV positive) or prevention self-efficacy (HIV negative), depression and stigma as well as disclosure, knowledge of partner status, and identification of discordant couples in intervention versus control facilities. Analysis of the cost-effectiveness of the IMPROVE intervention will also be conducted. In addition, qualitative interviews and focus group discussions will be conducted with study women, health care workers (HCW), LENASO, and VHWs to evaluate the feasibility and acceptability of integrating this intervention into routine care.
