Study of HIV, HCV, APS and Phylogenetics for PWID (SHARP)

17. november 2022 opdateret af: Carey Farquhar, University of Washington

Integrating Assisted Partner Services and Phylogenetics for HIV and HCV Prevention

This study will determine whether assisted partner notification services (APS) can identify and link to care, the sexual and needle-sharing partners of HIV-infected and HIV/hepatitis C (HCV) co-infected persons who inject drugs (PWID). It will also define the risk factors for onward HIV and HCV transmission among PWID using viral phylogenetics.

Detaljeret beskrivelse

Overview: This NIH-funded study uses assisted partner services (APS) to identify HIV-infected and HCV-infected persons who inject drugs (PWID) in Kenya and link them to care. In addition to determining the role of APS in HIV and HCV case-finding for this hard-to-reach key population, we leverage our experience with HIV and HCV phylogenetics in the US and South Africa to define modes and risk factors for onward viral transmission. The specific aims of the proposal are as follows:

AIM 1. To determine whether contact tracing and partner notification practices, known in Kenya as assisted partner services (APS), can identify and link to care, the sexual and injection partners of HIV-infected and HIV/ hepatitis C (HCV) co-infected persons who inject drugs (PWID).

AIM 2. To define the risk factors for HIV transmission among PWID, and to elucidate the role of PWID in the overall Kenyan HIV epidemic, using viral genetic sequencing techniques.

AIM 3. To characterize the modes and risk factors for onward HCV transmission among PWID using viral genetic sequencing.

Design: We will enroll 1000 HIV-infected PWID through a needle and syringe exchange program (NSP) in Nairobi, Kenya. Each index participant will undergo a structured questionnaire, a rapid HCV test, a blood draw, and will provide locator information regarding their sexual and injection partners from the past 3 years. Study staff will then attempt to locate all partners. Once located, partner participants will undergo rapid HIV and HCV testing, a structured questionnaire, and a blood draw. All blood samples will be sent to a central laboratory in Nairobi for processing. Dried blood spot samples will be created in Nairobi and will later be sent to the University of KwaZulu-Natal for quantitative viral loads for both HIV and hepatitis C, and follow-up phylogenetic testing. All participants who test positive for HIV or hepatitis C will be referred for counseling and treatment. HIV care and treatment will take place at multiple local centers offering these services.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Assisted Partner Services
All participants in this arm will be offered assisted partner services (APS) which involves outreach to sexual partners and to individuals with whom they use injection drugs. When partners are contacted they are offered HIV and HCV testing. There is no comparison arm.
Contact tracing for sexual and drug-sharing partners to notify about exposure to HIV and offer HIV and hepatitis C testing with linkage to care and partner services for those who test positive.

IPD-planbeskrivelse

The proposed studies will include the following data: self-reported demographic and behavioral data, medical/sexual histories, HIV/HCV test results, and HIV/HCV genetic sequences. To facilitate the data sharing process, we will consider the need for data sharing in the study design, creation of informed consent documents, and the structure of data collection. Release of completed viral gene sequences (on NCBI Genbank) shall occur during the project, if appropriate, or at the end of the project, consistent with normal scientific practices.
