Active clinical trials for "Acquired Immunodeficiency Syndrome"

Cognitive deficits in HIV reflect degraded brain network functioning that may be amenable to remediation through cognitive training. In this sub-study, we will make use of Plasticity-based Adaptive Cognitive Remediation (PACR), which applies well-understood techniques derived from brain plasticity and implicit/procedural/perceptual learning to improve the speed and accuracy of information processing, with exercises that are designed to drive generalized improvements. Simultaneously, these exercises heavily engage neuromodulatory systems to re-establish their normal control over learning and memory. As an individual restores these degraded abilities through intensive procedural learning, the encoding of naturalistic information significantly improves, and all resulting declarative memory and cognitive functions based on the quality of that incoming information necessarily improve as well, leading to improvement that generalizes beyond the trained tasks. A subset of 80 HIV+ individuals will undergo eight weeks of PACR to determine its feasibility and appropriateness for people with mild cognitive difficulties related to HIV infection. The results of this study are expected to be pivotal in generating data to create an optimal training program aimed at stabilizing or improving brain function in HIV infected individuals experiencing cognitive decline.

This study examines the impact and cost associated with Suubi4Her, an innovative combination intervention that aims to prevent HIV risk behaviors among 15-17 year-old girls living in communities heavily affected by poverty and HIV/AIDS in Uganda. Participants will be randomly assigned at the school level into one of three study conditions: 1) Savings (Youth Development Accounts - YDA) - with a 1:1 incentive match rate - for education and microenterprise development; 2) Savings (YDA) + Multiple Family Groups intervention; 3) Control condition receiving standard health and sex education provided in schools. The intervention will last for 24 months. Assessments will be conducted at baseline, 12, 24 and 36 months. Assessments will include biologically confirmed STIs, proportion of HIV infections during the study period, and for HIV+ participants markers for ART adherence. The study aims to examine the impact of the Suubi4Her intervention on behavioral health functioning, and protecting adolescent girls against known HIV risk factors. The study will also examine the cost-effectiveness of each intervention condition.

African Americans have considerably higher rates of HIV infections than do White, Hispanic, Asian, and Native Americans. African Americans accounted for 59% of all diagnoses of HIV infection among youth (13-24 years of age) in the United States. Young African Americans also have disproportionately high rates of other sexually transmitted infections (STIs). Therefore, the broad, long-term objective of this research is to identify interventions to reduce the risk of HIV and other STIs among young African Americans. Entertainment-education refers to narrative interventions designed to change behavior while providing entertainment. Several studies have evaluated the impact of media content on HIV risk behavior. One study found that exposure to an entertainment-education based HIV testing campaign was associated with increases in HIV testing among sexually active teens 12 months post exposure. Similarly, a radio soap opera called "Twende na Wakati" became the most popular television show in Tanzania and was highly successful in reducing the number of sexual partners and increasing condom use. A narrative video intervention study in STI clinic waiting rooms in three U.S. cities found a significant reduction in STI re-infection among patients visiting during months when the video was shown compared with patients visiting during months when it was not shown. Although these studies show that entertainment-education can be a promising medium for behavior change, none of them evaluated the efficacy of a tailored online entertainment-education intervention specifically designed for African American youth. To address this gap in the literature, this study tested the preliminary efficacy of an innovative, theory-based HIV risk-reduction serial drama intervention, Reality Check, specifically tailored to young African Americans. We used a randomized controlled trial, allocating African Americans 18 to 24 years of age to Reality Check, or an attention-control intervention promoting physical activity. Each intervention was delivered as a series of videos streamed online and accessible via any Internet-capable device. Participants completed surveys online at baseline, immediately post intervention, and 3 months post intervention. We hypothesized that, Reality Check would reduce condomless sex during the 3-month post-intervention period compared with the attention-matched control group, adjusting for baseline of the criterion.

There is a theoretical possibility of a complete suppression of HIV viral replication, subject to the use of highly active associations of more than 25 antiretroviral drugs currently available and good treatment adherence. But a key question remains: whether it can persist viral replication low noise HAART, since several arguments suggest a subclinical escape of the virus to HAART at least in some individuals. The technique proposed in this research consists of the detection and quantification of the linear viral cDNA intra cytoplasmic, as persistent novo infection marker in order to highlight the subclinical replication active in treatment of HIV-1 and consider an optimized therapeutic management of patients. Main objective : Comparing the frequency of patients infected with HIV and treated effectively (HIV viral load undetectable plasma with conventional methods) having the HIV DNA into the cytoplasm of their CD4 + T cells from peripheral blood, as cellular infection marker novo persistent, among patients with a therapeutic regimen contains or not the viral integrase inhibitor raltegravir. Secondary objectives To evaluate the frequency of patients infected with HIV and treated effectively with the HIV DNA into the cytoplasm of their CD4 + T cells from peripheral blood Evaluate the causes of persistent infection in de novo virological responders to treatment with ART: presence of the HIV genome encoding strains resistant to treatment ART ongoing noncompliance to treatment, type of antiretroviral therapy, CD4 nadir , pretreatment level of plasma HIV RNA, total duration of ART Assess the impact of persistent novo infection virological responders: cell activation CD4 + and CD8 +, lack of immunological treatment response, changes in lymphocyte ratio T naïve / memory cells cells, the presence of transient increase viremia, residual viremia levels Identify virological responders may benefit from treatment intensification

PHAT Life: Preventing HIV/AIDS Among Teens, is a uniquely-tailored intervention designed for recently-arrested juvenile offenders on probation. The program will teach teens about HIV/AIDS, sexually transmitted infections, and safer decision-making. The PHAT Life Research Study is a 2-arm randomized controlled trial of the PHAT Life Intervention. The investigators will test and compare PHAT Life to the health promotion control group on adolescent risky sexual behavior, substance use, and theoretical mediators.

This study aims to assess and confirm the adequate immunogenicity and safety profile of the Sanofi Pasteur's DTaP-Hep B-IPV-PRP-T fully liquid combined hexavalent vaccine administered in HIV-exposed uninfected infants and in HIV-exposed infected infants. The primary objectives of the study are: To evaluate the immunogenicity of the study vaccine 1 month after the 3-dose primary series in HIV-exposed infected and in HIV-exposed uninfected infants. To describe the persistence of all antibodies before receipt of the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. To evaluate the immunogenicity of the study vaccine 1 month after the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. The secondary objectives of the study are: To describe the safety profile after each and all doses of the study vaccine administered as a 3-dose infant primary series in HIV-exposed infected and in HIV-exposed uninfected infants. To describe the safety profile of the study vaccine administered as a booster in HIV-exposed infected and in HIV-exposed uninfected infants.

The primary objective of the proposed phase I trial is to evaluate the safety and tolerability of DNA-HIV-PT123 and AIDSVAX®B/E combination regimen. Though both DNA-HIV-PT123 and AIDSVAX®B/E and the combination of the two vaccines have been evaluated in humans and have shown to be safe and well tolerated, this is the first time the combination regimen is being evaluated in HIV-1 uninfected African populations with and without S. mansoni. The secondary objective of the trial is to evaluate the effect of S. mansoni infection on the immunogenicity of the combination of DNA-HIV-PT123 and AIDSVAX® B/E vaccine regimen. Successful vaccination against most viruses requires efficient Th1 response. There is evidence that helminth infections skew the host immune system of human and animals to T-helper type 2 (Th2) and induce immunosuppression. Therefore, there is a potential that helminth infected populations may not generate the desired immune responses to vaccines designed to drive Th1-type and cytotoxic T-cell responses. Furthermore, the influence of helminth infections on the development of protective antibody responses remains unclear. Limited data in animal models suggests that worm infections reduced efficacy of vaccines. The proposed vaccine trial will generate safety, tolerability and immunogenicity data of a vaccination regimen with simultaneous administration of a candidate HIV DNA vaccine (DNA-HIV-PT123) and a gp120 protein vaccine (AIDSVAX®B/E). This will be the first HIV vaccine trial to prospectively evaluate the impact of the S. mansoni infection on safety and immune responses to HIV vaccines.

The purpose of the study is to develop and pilot-test a home-based intervention to facilitate sate HIV testing and disclosure within pregnant couples in order to increase use of prevention-of-mother-to-child-transmission (PMTCT) and family health services in Kenya.

This is a research study in Kenya that will examine the outcomes of participants aged 10-15 and 16 and older; and provider acceptability of the Shang Ring technique for male circumcision that would simplify use. The study will be in two phases: Phase 1 will explore the no-flip technique that has been used in China but will be used for the first time in Africa. Phase 2 will be a randomized trial comparing use of tropical vs. injectable anesthesia.
