A Cohort Approach to Real-Time Detection of Acute HIV Infections Among People Who Inject Drugs in St. Petersburg, Russia.

ABSTRACT: To detect acute HIV infections (AHIs) in real time among people who inject drugs (PWID) in St. Petersburg, Russia and to test the feasibility of this approach. Prospective cohort study. One hundred seronegative or acutely HIV-infected at screening PWID were enrolled and followed until the end of the 12-month pilot period. Each participant was evaluated, tested, and counseled for HIV monthly. Two HIV tests were used: HIV antibody and HIV RNA PCR. If diagnosed with AHI, participants were followed weekly for a month; then, monthly for 3 months; and then, quarterly for the duration of the follow-up period. HIV risk behavior was assessed at each study visit. Most enrolled PWID were 30-39 years old, male, completed high school or more, not employed full-time, heroin users, and frequently shared injection paraphernalia. AHI prevalence at screening was 1.8% [95% confidence interval (CI): 0.4, 5.5]. Three participants with AHI at enrollment represented 3% (95% CI: 0.6, 8.5) of the 100 participants who consented to enroll. Among the HIV-uninfected participants (n?=?97), the AHI incidence over time was 9.3 per 100 person-years. Persons with AHI were more likely to report alcohol intoxication within the prior 30 days. This was the first study to detect AHI using a cohort approach. The approach proved to be feasible: recruitment, retention, AHI detection, and virological endpoints were successfully reached. A cost analysis in a real-world setting would be required to determine if this strategy could be brought to scale. The study revealed continued high HIV incidence rate among PWID in St. Petersburg, Russia and the importance of prevention and treatment programs for this group.

Project description:BackgroundThe HIV epidemic is intertwined with substance use and incarceration in Russia. The relationships between incarceration history, HIV treatment history, and stigma experiences among people with HIV (PWH) who inject drugs in Russia have not been well described.MethodsWe conducted a cross-sectional study of a cohort of PWH with opioid use disorder who inject drugs (n=201) recruited at a narcology (substance use treatment) hospital in St. Petersburg, Russia from September 2018 to December 2020. The primary analysis evaluated the association between self-reported prior incarceration and prior antiretroviral therapy (ART) initiation using multivariable logistic regression to adjust for demographic, social, and clinical covariates. We used multivariable linear regression models to analyze associations between prior incarceration and two secondary outcomes: HIV stigma score (11-item abbreviated Berger scale) and substance use stigma score (21-item combination of Substance Abuse Self-Stigma Scale and Stigma-related Rejection Scale).ResultsMean age was 37 (SD 5) years; 58.7% were male. Participants had been living with HIV for a mean of 13 (SD 6) years. Over two thirds (69.2%) of participants reported prior incarceration. One third (35.3%) of participants reported prior ART initiation. Prior incarceration was not significantly associated with prior ART initiation (AOR 1.76; 95% CI: 0.81, 3.83). Prior incarceration was associated with a lower HIV stigma score (adjusted mean difference in z-score: -0.50; 95%CI: -0.81, -0.19) but was not significantly associated with substance use stigma score (adjusted mean difference in z-score: -0.10; 95%CI: -0.42, 0.21).ConclusionPrior incarceration was common, and rates of prior ART initiation were low even though most participants had been living with HIV for at least a decade. We did not find an association between prior incarceration and prior ART initiation, which suggests a need to explore whether opportunities to initiate ART during or after incarceration are missed.Clinical trial numberNCT03290391.

Project description:IntroductionPolice violence against people who inject drugs (PWID) is common in Russia and associated with HIV risk behaviours. Sexual violence from police against women who use drugs has been reported anecdotally in Russia. This mixed-methods study aimed to evaluate sexual violence from police against women who inject drugs via quantitative assessment of its prevalence and HIV risk correlates, and through qualitative interviews with police, substance users and their providers in St. Petersburg, Russia.MethodsCross-sectional analyses with HIV-positive women who inject drugs (N=228) assessed the associations between sexual violence from police (i.e. having been forced to have sex with a police officer) and the following behaviours: current drug use, needle sharing and injection frequency using multiple regression models. We also conducted in-depth interviews with 23 key informants, including PWID, police, civil society organization workers, and other stakeholders, to explore qualitatively the phenomenon of sexual violence from police in Russia and strategies to address it. We analyzed qualitative data using content analysis.ResultsApproximately one in four women in our quantitative study (24.1%; 95% CI, 18.6%, 29.7%) reported sexual violence perpetrated by police. Affected women reported more transactional sex for drugs or money than those who were not; however, the majority of those reporting sexual violence from police were not involved in these forms of transactional sex. Sexual violence from police was not significantly associated with current drug use or needle sharing but with more frequent drug injections (adjusted incidence rate ratio 1.43, 95% CI 1.04, 1.95). Qualitative data suggested that sexual violence and coercion by police appear to be entrenched as a norm and are perceived insurmountable because of the seemingly absolute power of police. They systematically add to the risk environment of women who use drugs in Russia.ConclusionsSexual violence from police was common in this cohort of Russian HIV-positive women who inject drugs. Our analyses found more frequent injection drug use among those affected, suggesting that the phenomenon represents an underappreciated human rights and public health problem. Addressing sexual violence from police against women in Russia will require addressing structural factors, raising social awareness and instituting police trainings that protect vulnerable women from violence and prevent HIV transmission.

Project description:Background and aimsHIV infection and mortality in Eastern Europe are driven by unsafe injection drug use. We sought to compare engagement in care from HIV testing through receipt of antiretroviral treatment among HIV-positive people who inject drugs (PWID) in St Petersburg, Russian Federation (RF) and Kohtla-Järve, Estonia and identify factors associated significantly with failure to progress at each stage of the HIV treatment cascade.DesignCross-sectional biobehavioral surveys of PWID with an analysis stratified by location-two Russian-speaking regions with similar HIV epidemic histories and current prevalence.SettingField-based surveys conducted in St Petersburg, RF and Kohtla-Järve, Estonia.ParticipantsWe recruited 452 HIV-positive PWID in St Petersburg (November 2012 to June 2013) and 370 HIV-positive PWID in Kohtla-Järve (June-August 2012) using respondent-driven sampling.MeasurementsParticipants were tested for antibodies to HIV, and administered a questionnaire focusing on participants' medical care histories. Engagement in care was categorized as a cascade of five transitional steps through six stages, ranging from HIV testing to current receipt of antiretroviral medications.FindingsProgress along the cascade was greater in Kohtla Järve (32.7% were receiving antiretroviral medications) than in St Petersburg (9.7%). In both locations, we found the steps with high failure rates were the transitions from being aware of one's HIV diagnosis to being in regular care and initiation of highly active antiretroviral therapy (HAART). Factors associated significantly with transition failure in both locations and across steps included high alcohol consumption, variables associated with drug choice and injection frequency and lack of basic medical insurance.ConclusionThe two steps in treatment cascade for HIV-positive PWID in St Petersburg, RF and Kohtla-Järve, Estonia requiring greatest improvement are retention in regular care and initiation of HAART. Both individual behavioral and structural factors are associated with failure to transition along the cascade.
