Opioid Use Fueling HIV Transmission in an Urban Setting: An Outbreak of HIV Infection Among People Who Inject Drugs-Massachusetts, 2015-2018.

Objectives. To describe and control an outbreak of HIV infection among people who inject drugs (PWID).Methods. The investigation included people diagnosed with HIV infection during 2015 to 2018 linked to 2 cities in northeastern Massachusetts epidemiologically or through molecular analysis. Field activities included qualitative interviews regarding service availability and HIV risk behaviors.Results. We identified 129 people meeting the case definition; 116 (90%) reported injection drug use. Molecular surveillance added 36 cases to the outbreak not otherwise linked. The 2 largest molecular groups contained 56 and 23 cases. Most interviewed PWID were homeless. Control measures, including enhanced field epidemiology, syringe services programming, and community outreach, resulted in a significant decline in new HIV diagnoses.Conclusions. We illustrate difficulties with identification and characterization of an outbreak of HIV infection among a population of PWID and the value of an intensive response.Public Health Implications. Responding to and preventing outbreaks requires ongoing surveillance, with timely detection of increases in HIV diagnoses, community partnerships, and coordinated services, all critical to achieving the goal of the national Ending the HIV Epidemic initiative.

Project nGage: Network Supported HIV Care Engagement for Younger Black Men Who Have Sex with Men and Transgender Persons.

BACKGROUND: Young Black men who have sex with men and transgender persons (YBMSMT) aged 13-29 carry the nation's highest burden of new HIV infections. Studies indicate that YBMSMT have poor retention in care, which is associated with reduced medication adherence and increased virologic failure. OBJECTIVE: Project nGage is a randomized controlled (RCT) trial evaluating the feasibility and preliminary efficacy of a brief, dyadic intervention designed to promote adherence to HIV primary care in safety-net clinics. Network visualization is used to identify and engage a support confidant (SC) from participants' social networks. A social work interventionist then meets with the SC and SC-participant dyad to activate and maintain HIV-specific social support. METHODS: Project nGage is operating in two phases. In Phase I, the Team refined study protocols based on pilot testing. In Phase II, 94 HIV infected YBMSMT ages 16-29 will be recruited, enrolled and randomly assigned to receive Project nGage or treatment as usual (TAU). The primary outcome is appointment attendance; the secondary outcomes are medication adherence and viral load. RESULTS: Implementation challenges include coordinating sites, managing dyadic intervention logistics, and recruiting non-adherent patients or those who have fallen out of care. The team continues to address implementation issues as the study progresses. CONCLUSIONS: Project nGage is addressing a gap in HIV care-related research by focusing on supportive relationships as a mechanism through which to promote retention in care. Pending study results, a larger RCT would compare the relative effectiveness of the Project nGage intervention versus TAU over 18 to 24 months.
