Antiviral Pharmacology and Adherence in Drug Users

HEPATITIS CVirus1 more

Approximately one half of all Americans living with Hepatitis C virus (HCV) are drug users, yet they are the least likely to receive HCV treatment. Drug users are presumed non-adherent and therefore denied potentially life-saving therapy. This assumption can only be confirmed or dispelled through prospective pharmacologic and adherence studies in this population. Such studies would be greatly enhanced by an objective, quantitative measure of adherence which does not currently exist in the HCV field. Through the work proposed in this application, sixty HIV/HCV co-infected drug users will be treated with direct acting antiviral agents (DAA) and randomized to receive directly observed DAA therapy (DOT) vs. no directly observed therapy (no-DOT). Patients randomized to no-DOT will have wirelessly observed therapy (WOT) which involves use of a portable medication dispenser that sends a signal to a server with the date and time when the dispenser is opened. In Aim 1, DAA concentrations will be compared in those randomized to DOT vs. no-DOT. DAA pharmacokinetics will also be defined accounting for clinical factors like degree of hepatic impairment and use of concomitant recreational and antiretroviral drugs. The goal is to quantify adherence in this population and the effect of variable adherence on drug concentrations. In Aim 2, DAA concentrations (plasma, cellular, hair) will be linked with adherence patterns identified using WOT and DOT. The goal is to identify a drug concentration biomarker that predicts adherence in this population. In Aim 3, the relationship between DAA adherence (as measured by WOT and DOT and drug concentrations) and rate of cure will be established. The goal is to define the degree of adherence needed for HCV cure.

WelTelOAKTREE: Text Messaging to Support Patients With HIV/AIDS in British Columbia

HIVMedication Adherence

WelTel Oak Tree is a repeated measures study that enrolled 85 HIV+ individuals from the Oak Tree Clinic at BC Women's Hospital. Participants were be provided with a cell phone and/or unlimited text messaging capability if they do not have it already, and for one year received a weekly text message stating "How are you". Participant problems and non-responses were be followed up by a nurse. Data on demographics, CD4 counts, HIV viral loads, HIV medication adherence and attendance at appointments was collected for the year prior to the intervention and during the intervention for comparison. Data assessing quality of life was also collected at three points during the one year study period. Cost effectiveness and cost benefit of the intervention is being studied to assess feasibility of transferring the intervention to a programmatically funded facet of patient care.

Interventions to Improve HIV Care Engagement After Hospital Discharge

HIV/AIDS

A quasi-experitmental study of the efficacy interventions, including additional HIV care team daily inpatient round and three telephone calls to remind the upcoming clinic appointment, in improving HIV care engagement within 30 days after hospital discharge among HIV-infected patients.

SMS as an Incentive To Adhere (SITA) - An Intervention Communicating Social Norms by SMS to Improve...

Human Immunodeficiency Virus

The purpose of this study 'SMS as an Incentive To Adhere' (SITA) is to test two novel approaches of using SMS messages (provision of information about electronically measured own adherence, as well as in combination with group adherence level) to improve adherence to anitretroviral (ART) and pre-ART prophylaxis among youth age 15-24 at an HIV clinic in Uganda.

BRIDGE: Improving HIV Service Delivery for People Who Inject Drugs

Human Immunodeficiency VirusSubstance Abuse1 more

Scaling up integrated, cost-efficient HIV services for people who inject drugs (PWID) in Needle Syringe Programs (NSPs) is urgently needed in Kazakhstan, where only one-third of the estimated 19,000 HIV-positive PWID are ever linked to HIV care and only 10% initiate ART with 4% achieving viral suppression. The study's aim is to evaluate the implementation, effectiveness, and sustainability of an integrated HIV service model in 24 NSPs located in 3 Kazakhstani city areas. This model will employ highly effective strategies that will include peer-driven recruitment of PWID in NSPs using social network strategies (SNS), integrating rapid HIV testing in NSPs with HIV Care Clinic nurses, and linking HIV positive PWID in NSPs to HIV care using the ARTAS (Anti-Retroviral Treatment and Access to Services) case management model. Findings will have important public health implications for improving HIV service delivery for PWID in the Central Asian region and other countries with injection driven epidemics.

mHealthPMTCT5 more

The investigators are conducting a 3-arm randomized trial comparing the effects of unidirectional SMS (ie: "push" messaging to participant) vs. bidirectional SMS dialogue between participant and provider vs. control (no SMS) among HIV-infected Kenyan mothers in Kenyan PMTCT-ART for outcomes of ART adherence and retention in care.

Human Immunodeficiency Virus (HIV)

The goal of this study is to determine if there is a difference in shedding (primary objective) and in immunogenicity and safety (secondary objectives) between HIV-positive and HIV-negative children and young adults who are receiving the quadrivalent live-attenuated influenza vaccine (QLAIV).

Hybrid STTR Intervention for Heterosexuals: Anonymous Testing and Confidential Care Linkage

HIV/AIDS

The Brooklyn Community United (BCU) study is a supplement to the main research study titled "Peer Driven Intervention to Seek, Test, & Treat Heterosexuals at High Risk for HIV." The main study's field name is Brooklyn Community Action Project (BCAP) (R01DA032083, R#: 11-01257). The main study is testing two approaches to seeking out undiagnosed HIV infection (Venue-based Sampling (VBS) and Confidential Two-Session Testing with Navigation (CTTN-RDS)). HIV prevalence rates in two previous heterosexual cycles of NHBS in the local area are: 7% in HET1 and 12.3% in HET2. The main study, BCAP, found lower prevalence rates of 3.45%, 35.14% of which were newly diagnosed in the RDS-CTTN sample and 1.89% newly diagnosed with HIV in the VBS sample. The primary aim of the Brooklyn Community United (BCU) study is to seek out individuals with undiagnosed HIV using a streamlined RDS-CTTN approach, and anonymous HIV Testing in Central Brooklyn. The supplement study hypotheses are: (H1): Compared with VBS and RDS-CTTN, and controlling for potential differences on key socio-demographic characteristics across the samples, RDS-ASTN participants will have less HIV testing experience. (H2) Controlling for potential differences on key socio-demographic characteristics across the samples, RDS-ASTN will yield higher rates previously undiagnosed HIV compared with VBS and RDS-CTTN. (H3): Most participants (> 70%) found to be HIV-infected in the RDS-ASTN intervention will engage in the Treat and Retain intervention phase. (H4): Most participants in the Treat and Retain phase of the RDS-ASTN intervention (> 70%), all of whom will be HIV infected, will be linked to care within 3 months.

First Study to Evaluate the Capacity of Maraviroc Drug to Protect Against HIV Infection in Samples...

HIV

Pre-exposure prophylaxis (PrEP) is a method of preventing HIV infection through the use of antiretroviral (ARV) medications before exposure to HIV. This study will assess the potential of MVC as a "on demand" pre-exposure prophylaxis, within a strategy for the prevention of HIV infection in men who have sex with men (MSM).
