Although poor antiretroviral (ART) adherence in HIV does not mean a complete lack of therapeutic results, the benefit of ART increases as adherence improves. Consequences of suboptimal ART adherence are viral rebound, development of drug-resistant HIV strains, and more rapid progression to AIDS. Moreover, HIV-infected persons tend to have numerous co-occurring conditions and therefore take many medications making adherence to multiple drug regimens more difficult. A mobile application capable of improving medication adherence among HIV-infected persons would be highly useful. The investigators propose an intervention study designed to address these potential mechanisms of nonadherence by utilizing the Care4Today v2.0 smartphone application (app). The current study is a small pilot Randomized Controlled Trial (RCT) comparing the smart phone application titled "Care4Today v2.0" versus standard of care to improve medication adherence to ART over a 4-week period with 60 HIV-infected participants. The pilot RCT consists of 60 HIV-infected persons who are at risk for ART medication nonadherence. Using random assignment, 30 HIV-infected participants will be assigned to medication adherence improvement via "Care4Today" app as compared to 30 HIV-infected participants assigned standard of care. The investigators will assess the effectiveness and acceptability of the app in improving objectively measured ART adherence (i.e., via medication event monitoring system caps) over a 4-week period via a pilot RCT with 30 HIV-infected persons assigned to the Care4Today intervention and 30 HIV-infected persons assigned to standard of care.
This trial will pilot test intervention strategies to increase utilization of HIV testing and gain knowledge for designing a clinical trial to evaluate prevention strategies to reduce HIV sexual transmission in the general population in Russia. The study will assess whether external (cost, convenience) or internal factors (low perception of own risk, reluctance to identify a partner as at-risk, fear of stigma) drive Russian women's reluctance to be tested and if peer support impacts their decision. A randomized experimental manipulation, comparing opt-in vs. bundled opt-out testing approaches, followed by focus group discussions, followed by a second-chance testing offer will be used to inform these questions. The answers will enable the international research team to engineer and then test an HIV testing promotion strategy in Russia. The project will collect preliminary data for a larger study to develop an evidence-based program to reduce the HIV transmission in this high risk population.
Investigators hypothesize that older HIV-infected individuals (i.e., >50 years old) on efavirenz (EFV)-containing antiretroviral therapy (ART) will have significantly worse neurocognitive function than older individuals on non-EFV-containing ART.
In this proposed study with People Living with HIV/AIDS (PLWHA), we will use a stepped care model called a Sequential Multiple Assignment Randomized Trial (SMART) to examine the efficacy of low- and high-intensity smoking cessation treatments for nicotine dependent PLWHA that incorporate the current standard of care and prize-based contingency management. Intervention will be administered in a community-based HIV integrated care clinic in downtown Detroit, which has the highest prevalence rates of HIV/AIDS and smoking in Michigan. Phase 1 will last 4 weeks, and will involve brief intervention to help participants stop smoking. For phase 2, participants will be assigned to different study arms depending on whether they are Responders (reduced their smoking) or Non-responders (continued to smoke). 1. Phase 1: We hypothesize that brief high-magnitude prize contingency management will result in greater reduction in smoking than standard of care alone. 2. Phase 2a: We hypothesize that non-responders who are assigned to contingency management will be more likely to reduce their smoking throughout treatment and to abstain from smoking at all follow-up points. 3. Phase 2b: We hypothesize that responders who are assigned to monitoring and low-magnitude prize contingency management will be more likely to maintain their reduced or abstinent smoking status at all follow-up time-points.
This pilot single arm, single site, open-labeled switch study seeks to enroll thirty (30) HIV positive patients infected with CCR5 tropic virus that have achieved an undetectable viral load on a non-Selzentry®-containing regimen [Protease Inhibitor (PI)/Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI)/Integrase Inhibitor plus 2 Nucleoside Reverse Transcriptase Inhibitor (NRTI)] and switch them to once-daily Selzentry® (600mg qd) plus the same 2 NRTIs.
Formative Research Phase (Months 1-6) The investigators will undertake qualitative formative studies to: (1) identify barriers to highly active antiretroviral therapy (HAART) and strategies currently used to engage PLH in care; (2) identify access points and ways to reach a diversity of PLH social networks; (3) gain an understanding of PLH views, motivations, barriers, and facilitators of care entry, maintenance, and adherence; (4) examine the structure and segments of the PLH community in St. Petersburg; and (5) elicit input from members of the PLH community and its stakeholders concerning the planned network recruitment, assessment, and intervention procedures and content. The investigators will refine protocols used in their intervention pilot study based on findings of the formative research phase. Main Trial Phase (Months 7-60) Overview of the main intervention outcome trial's experimental design. The main trial is a two-arm randomized outcome study. A total of 32 sociocentric social networks of PLH will be recruited by first identifying initial seeds—always PLH who are either out-of-care or treatment nonadherent—in multiple access points that were identified in the formative phase. The investigators will then enroll three rings of HIV+ friends outward beginning with each seed. Each sociocentric network is expected to consist of approximately 16 to 18 individuals (expected n=32x18=576 participants). This estimate is based on the size and density of participants' personal networks observed in our pilot studies. Each network member will be assessed at baseline using measures to be described shortly and will receive individual motivational counseling in care and adherence. This session will "prime" participants to an understanding about the availability, accessibility, and benefits of care. Members of the 16 PLH networks randomized to the experimental condition will then receive the network intervention. Cadres of empirically identified influence leaders within each network will be identified, trained, and engaged to reinforce network member engagement and adherence. At 6- and 12-month followup points, assessment data will again be collected to determine intervention impact on the primary and secondary outcomes.
Tat Oyi vaccination on seropositive patients could help their immune system to recognize and neutralize Tat. The neutralization of extra cellular Tat should help the cellular immune response to eliminate HIV-1 infected cells.
The overall goal of this project is to implement and evaluate a community-level, structured approach to enhance HIV care access and retention for drug users in San Juan, Puerto Rico. The "Enhanced HIV Care Access and Retention Intervention" will: 1) identify drug users living with HIV who either do not know their HIV status and/or are not engaged in HIV care; 2) provide direct HIV care services through a mobile health van; and 3) support identified HIV-infected drug users with patient navigators to enhance their ability to engage in HIV care and substance abuse treatment, to initiate antiretroviral therapy, and maintain adherence to their treatment regimens. The structural enhanced care approach will be evaluated through a randomized roll-out design, a refinement of the stepped-wedge design. The community-level success of the intervention will be assessed by evaluating virologic suppression (primary biological outcome), increased attendance to HIV care visits, uptake of antiretroviral therapy, adherence to HIV treatment regimens, and decreased substance use (as secondary behavioral outcomes) in an independent cohort of HIV-positive individuals drawn from each of the neighborhoods included in the intervention. The investigators will also evaluate the implementation process and cost of the enhanced care approach including implications for cost-effectiveness, feasibility of expansion, and sustainability.
This is a pilot, monocentric, prospective, randomized control trial looking at the use of rapid tests as a part of normal care. The investigators will be testing for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). Testing will be proposed to all persons seeking care at the Centre d'Accueil, de Soins et d'Orientation from the organization Médecin du Monde (CASO, MDM). Infection status of participants will be determined by either the standard test (ELISA) or rapid test. The choice between tests will be determined randomly. The overall goal is to determine the general acceptability and feasibility of rapid tests and to see if they can help individuals increase their awareness of infection status when compared to longer, routine methods of testing. In addition, results from these tests will allow the medical doctor to guide participants to appropriate care. All positive tests will be confirmed at a specialized hospital (Hôptial Saint-Antoine, Paris, France) and health-specific information will be obtained four months after testing.
