STRIDE2 is a longitudinal, non-randomized study of individuals living with HIV who are dependent on opioids. This study is funded by the National Institute on Drug Abuse (R01DA030768, Altice, PI; Taxman \& Lawson, Co-PIs) and is being conducted by George Mason University, Yale University, and Howard University.
The purpose of this study is to test the effectiveness and implementation of a brief, integrated behavioral intervention for HIV medication adherence and substance use in the HIV care setting in South Africa. The intervention is specifically designed to be implemented by non-specialist counselors using a task sharing model in local HIV clinics. The behavioral intervention will be compared to usual care, enhanced with referral to a local outpatient substance use treatment program (Enhanced Standard of Care - ESOC) on study endpoints (as described in study endpoint section below).
The purpose of this study is to use technology to improve symptom status and ultimately improve patient centered outcomes in people living with HIV/AIDS (PLWHA). The primary purpose of the intervention (VIP-HANA) is to improve symptom status. The investigators hypothesize that VIP-HANA will improve symptom frequency and intensity.

The purpose of the study are the following: 1) Pilot test and conduct baseline and 3 month follow up assessments to evaluate the preliminary efficacy of the DVD-based HIV/HCV intervention by randomly assigning 210 Latino corrections-involved, outpatient abuse treatment clients to either the experimental intervention or to a wait list control group; and 2) to evaluate both participant and interventionist acceptability of this novel DVD-based intervention. They study hypothesis are the following: 1. participants in the intervention condition will report greater reductions in sexual risk behaviors (e.g., unprotected sexual contact) from baseline to 3 month follow-up compared to the control group; 2. participants will report greater reductions in drug risk behaviors (e.g., sharing injection equipment, drug use during sex) from baseline to 3 month follow-up compared to the control group; 3. participants who report more HIV prevention information, motivation, and behavioral skills will report fewer sexual risk behaviors.
Background: - The human immunodeficiency virus (HIV) causes acquired immune deficiency syndrome (AIDS). Combination antiretroviral therapy (ART) drugs treat HIV infection. They generally decrease the amount of HIV virus in the blood (called viral load) to very low levels. This happens only if the drugs still fight HIV and if taken every day exactly as prescribed. When not taken as directed, or if the ART drugs are not strong enough, the virus can become resistant to them, and the ART will not work to control the virus. Researchers want to know how to control HIV in people who can t lower their viral load with their current ART drugs. Objective: -\<TAB\>To better control HIV in people who can t get a lower viral load even with ART drugs and to learn more about why the HIV is not under control. Eligibility: * People at least 18 years old and with HIV. * People who have been on at least two combinations of ART drugs (including current ART). * People whose last two viral loads were greater than 1,000 copies/mL. Design: * Participants will be screened with medical history, physical exam, and blood tests. * Participants will then have a baseline visit. They will have another physical exam, blood tests, plus answer questions about what they know about HIV and ART, and how they take their ART. * Participants will arrange to stay in the NIH hospital for 7 8 days. * They will take their medications as usual. At the time to take the ART drugs, they will have to ask a nurse to bring them. If they forget, the nurse will bring them. * Participants will meet with a doctor, pharmacist, social worker and nurse to discuss ways to help participants remember to take their drugs. * Participants will have blood drawn about every other day. * Researchers will study the test results. Some participants will be put on different ART drugs. If that happens, participants will have another NIH hospital stay for 7-8 days. * Participants will have 4 follow-up visits over 12 weeks, then every 3 months for 2 years or more.
The primary objective of this project is to assess the study population's acceptance of two medication adherence support strategies: incentive-based programs and electronic medication monitoring. The study population is adolescents (ages 16 - 24) positive for human immunodeficiency virus (HIV) currently undergoing treatment with antiretrovirals at St. Jude's HIV clinic. Participation in the study will involve completion of a survey: an Audio Computer Assisted Self Interview (ACASI). The duration of the survey is anticipated to be 10-20 minutes. Patient identifiers will not be attached the survey.
The purpose of this project is to gather pilot data related to risk factors associated with suicide in Veterans with Human Immunodeficiency Virus (HIV)/ Acquired Immune Deficiency Syndrome (AIDS) and to develop an educational and interventional tool and instructional guide that can be utilized by local and national providers to increase understanding regarding suicide risk assessment. There are no hypotheses associated with this qualitative pilot study.
The aims of STRIDE were changed as of July, 2014. The revised project, called STRIDE2, has a longitudinal, non-randomized, observational study design. The population under study consists of individuals living with HIV who are dependent on opioids.
The principal goal of this research project is to evaluate the natural history of HCV and liver disease and its treatment in HIV-infected persons who use drugs. Research procedures will focus on determining liver disease prevalence and severity within this population. This is an observational study without study specific interventions.
The chief purpose of this research is to understand how antiretroviral therapy (ART) affects progression of liver disease in persons co-infected with HIV and hepatitis C virus (HCV). The investigators study liver disease progression in a cohort of dually infected persons according to the success of ART.
The chief purpose of this research is to evaluate interferon alpha sensitivity and cell type specific levels of interferon receptor and interferon stimulated genes and proteins in HIV/ HCV (hepatitis C virus) coinfected persons before and after administration of HIV medications (antiretroviral therapy).
This is a randomized controlled trial of injectable intramuscular naltrexone (XR-NTX) versus intramuscular placebo among HIV-infected prisoners meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for alcohol dependence or problem drinking, who are transitioning to the community and seeking treatment to prevent relapse to alcohol use. We hypothesize that extended release naltrexone (XR-NTX) will result in improved HIV outcomes (lower log10 HIV-1RNA levels and higher CD4 count) as well as improved alcohol treatment outcomes, and reduced drug/sex HIV related risk behaviors and decreased rates of reincarceration.
This phase 2b study is designed to assess the long-term efficacy (24 weeks) of MPC-4326 in combination with a 2-3 drug optimized background regimen (OBR) relative to the efficacy of a 3-4 antiretroviral (ARV) regimen in treatment experienced, HIV-1 infected subjects.
People infected with HIV are now living longer lives because of the use of highly active antiretroviral therapy (HAART). However, HAART medications have been shown to increase the risk of cardiovascular disease and metabolic dysfunction in adults. More research is needed on the effect of HAART in children. The purpose of this study is to assess cardiovascular risk factors in children infected with HIV who receive HAART medications and to determine the effectiveness of an exercise program on cardiovascular outcomes in these children.
Through a prospective observational cohort study enrolling patients newly diagnosed with Human immunodeficiency virus (HIV): Aim 1: Assess attitudes and beliefs about HIV disease and care over time and relate those attitudes and beliefs to success in following the Steps of HIV Care. Aim 2: Validate a simple visual analogue scale for assessing adherence to highly active antiretroviral therapy (HAART) in patients newly starting HAART in routine care. Aim 3: Implement latent growth curve analysis for modeling changes in attitudes and beliefs over time, and for assessing the impact of the components of the Steps of HIV Care model on health outcomes.
The main objective of this study is to observe the long-term safety of elvitegravir (EVG) boosted with ritonavir (RTV) in combination with other antiretroviral (ARV) agents in participants who have completed a prior EVG+RTV treatment study.
This study will identify genetic factors associated with the development of progressive multifocal leukoencephalopathy (PML) in patients with acquired immunodeficiency syndrome (AIDS). PML is a life-threatening infection of the brain that affects about 5 percent of untreated patients with AIDS. Its symptoms include mental deterioration, vision loss, speech disturbances, ataxia (inability to coordinate movements), paralysis, and coma. PML is caused by a polyomavirus called the JC virus. It is estimated that up to 80 percent of the human population has been exposed to the JC virus, but the disease is very rare. The virus only becomes active in people who have compromised immune systems, such as those undergoing immune suppressive chemotherapy for cancer and those with damaged immune systems due to HIV. Patients who have participated in the Multicenter AIDS Cohort Study may be eligible for this study, as well as healthy normal volunteers who will serve as controls. The study will review clinical information from patients and analyze genetic factors from both patients and control subjects to investigate genes associated with AIDS and JC virus infection.
Recent studies have shown that many drug-using minority women are vulnerable to HIV infection from their husbands or other intimate male partners. The goal of this study is to develop and evaluate two new HIV counseling and testing programs designed for drug-using women at risk for HIV from a primary male partner. It is predicted that HIV counseling and testing programs administered to couples rather than to women only, and programs that focus on intimate relationships in the context of HIV risk, will result in a reduction of risky sexual and drug-related behavior among drug-using women and their primary male partners. This four-year study employs a randomized clinical trial (RCT) design to test the effectiveness of two new HIV counseling and testing programs for women drug-users in Harlem and the South Bronx in New York City.
