Dumchev K, Kovtun O, Salnikov S, Titar I, Saliuk T. Integrated biobehavioral surveillance among people who inject drugs in Ukraine, 2007-2020. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024:104319. [PMID: 38216437 DOI: 10.1016/j.drugpo.2024.104319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 12/16/2023] [Accepted: 01/02/2024] [Indexed: 01/14/2024]
Abstract
BACKGROUND Repeated integrated biobehavioral surveys (IBBS) have been implemented among people who inject drugs (PWID) in Ukraine to monitor the trends in key epidemiologic and programmatic indicators. METHODS The study analyzed seven PWID IBBS rounds from 2007 to 2020 in seven Ukrainian cities. Participants were recruited using respondent-driven sampling, tested for HIV and anti-HCV antibodies, and completed a structured questionnaire. Composite weights (based on individual sampling probability and population size) were applied to generate point estimates and confidence intervals for HIV and HCV prevalence, injection risk behaviors, prevention service coverage, and HIV treatment cascade. Multi-level regression assessed temporal trends in these indicators in 2007-2020. RESULTS The samples consisted of 1587 participants in 2007, 1905 in 2008/9, 3066 in 2011, 2846 in 2013, 2699 in 2015, 2798 in 2017, and 3651 in the 2020 rounds. HIV prevalence decreased from 27% to 19% overall, and among PWID younger than 25 from 10.5% to 5.5%. Anti-HCV prevalence increased from 50% to 73% overall but decreased from 58% to 27% in the younger subgroup. Past-30-days injection risk behaviors consistently decreased, reaching a minimum of 38% for any risk in 2020. HIV treatment cascade indicators and coverage with opioid agonist treatment substantially improved in the last three rounds. Harm reduction services coverage fluctuated, declining from 52% to 33% in the last three rounds. CONCLUSIONS This analysis demonstrates the potential of repeated IBBS for monitoring the HIV epidemic and program coverage. We confirmed a sustained decline in overall HIV and HCV transmission, likely driven by reduced risky injection practices among PWID. The impact of harm reduction services requires further study. HIV status awareness and treatment coverage among PWID markedly increased, reaching the national average, possibly indicating the success of case-finding and linkage-to-care interventions. The upcoming IBBS round in Ukraine will also assess the impact of the war on service provision, risk behavior, and HIV transmission among PWID.

"Maintaining HIV and HCV prevention and care for people who inject drugs despite COVID-19 in Hai Phong, Vietnam". THE INTERNATIONAL JOURNAL OF DRUG POLICY 2022; 110:103870. [PMID: 36244242 PMCID: PMC9489978 DOI: 10.1016/j.drugpo.2022.103870] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 08/31/2022] [Accepted: 09/15/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND After the emergence of COVID-19, a one-month strict lockdown was imposed in April 2020 in Vietnam, followed by lighter social distancing restrictions over the year. We investigated whether those measures affected people who inject drugs (PWID) in terms of risk behaviors for HIV and HCV and access to prevention and care in the city of Haiphong, a historic hotspot for HIV and drug use. METHODOLOGY We carried out a 'before-after' study from 2019 to 2020 using respondent-driven sampling method to enroll PWID. They were interviewed on their socioeconomic situation, drug use and sexual behaviors, relations to care services and tested for drugs and methadone in the urine, for HIV, HCV, and HIV plasma viral load when HIV-positive. Changes following the restrictions were assessed by comparing 'before' to 'after' data. RESULTS 780 PWID were enrolled. Mean age was 44 years; 94% were male. All were actively injecting heroin 'before', versus 56% 'after'. Among those, frequency of consumption decreased from 24 to 17 days per month. No changes were observed in the frequency and practices of methamphetamine smoking. The proportion of PWID on MMT increased from 68.7% to 75.3%, and that of PWID engaging in risky behaviors related to drug injection decreased from 6.0% to 1.5%. No HIV seroconversions were observed; HCV incidence was 2.6/100 person-years (95% CI [0.7-6.7]). 9% of PWID reported a monthly income of less than 130USD 'before' versus 53% 'after'. CONCLUSION The case of Hai Phong shows that it is possible, during times of COVID-19 pandemic, to maintain access to harm reduction and care and to prevent HIV and HCV transmission among PWID in a resource-limited setting where severe social distancing restrictions are implemented. Further research is needed to assess the consequences of long-term economic difficulties and the impact of actual spread of SARS-Cov2 that has since emerged in Haiphong.

Abstract
BACKGROUND In most low-to-middle-income countries, HIV control at the population level among people who inject drugs (PWID) remains a major challenge. We aimed to demonstrate that an innovative intervention can identify HIV-positive PWID in the community who are not treated efficiently, and get them treated efficiently. METHODS Between 2016 and 2020, we implemented an intervention consisting of mass HIV screening of PWID using three annual respondent-driven sampling surveys (RDSS) and a post-intervention evaluation RDSS in community-based organisation (CBO) sites, coupled with peer support to facilitate/improve access to antiretroviral and methadone therapy in Haiphong, Vietnam. The primary outcome was the proportion of identified uncontrolled HIV-positive PWID who achieved viral control. We also estimated the potential effect of the intervention on the proportion of PWID with HIV RNA >1000 copies/mL among all PWID during the study period. FINDINGS Over the three RDSS, 3150 different PWID were screened, i.e. two-thirds of the estimated population size. They all injected heroin, their median age was of 39 years, 95% were male, 26.5% were HIV-infected, and 78.6% of the latter had HIV RNA ≤1000 copies/mL. Among the 177 PWID identified with an unsuppressed viral load, 73 (41.2%) achieved viral suppression at the final visit. HIV viremia decreased from 7.2% at baseline to 2.9% at the final RDSS (p<0.001). Up to 42% of this observed reduction may be explained by the intervention, in the absence of any external intervention targeting PWID during the study period. INTERPRETATION Mass community-based screening using RDSS coupled with CBO support is a powerful tool to rapidly identify untreated HIV-positive PWID and (re)link them to care.

Drug Alcohol Depend 2022; 238:109573. [PMID: 35926301 PMCID: PMC9278993 DOI: 10.1016/j.drugalcdep.2022.109573] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 06/30/2022] [Accepted: 07/09/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND We explore injecting risk and HIV incidence among PWID in New York City (NYC), from 2012 to 2019, when incidence was extremely low, <0.1/100 person-years at risk, and during disruption of prevention services due to the COVID-19 pandemic. METHODS We developed an Agent-Based model (ABM) to simulate sharing injecting equipment and measure HIV incidence in NYC. The model was adapted from a previous ABM model developed to compare HIV transmission with "high" versus "low" dead space syringes. Data for applying the model to NYC during the period of very low HIV incidence was taken from the "Risk Factors" study, a long-running study of participants entering substance use treatment in NYC. Injecting risk behavior had not been eliminated in this population, with approximately 15 % reported recent syringe sharing. Data for possible transmission during COVID-19 disruption was taken from previous HIV outbreaks and early studies of the pandemic in NYC. RESULTS The modeled incidence rates fell within the 95 % confidence bounds of all of the empirically observed incidence rates, without any additional calibration of the model. Potential COVID-19 disruptions increased the probability of an outbreak from 0.03 to 0.25. CONCLUSIONS The primary factors in the very low HIV incidence were the extremely small numbers of PWID likely to transmit HIV and that most sharing occurs within small, relatively stable, mostly seroconcordant groups. Containing an HIV outbreak among PWID during a continuing pandemic would be quite difficult. Pre-pandemic levels of HIV prevention services should be restored as quickly as feasible.

Implementation of respondent driven sampling in Nairobi, Kenya, for tracking key family planning indicators among adolescents and youth: lessons learnt. BMC Res Notes 2022; 15:200.

Abstract
OBJECTIVE Adolescents and youth constitute a significant proportion of the population in developing nations. Conventional survey methods risk missing adolescents/youth because their family planning/contraception (FP/C) behavior is hidden. Respondent-driven sampling (RDS), a modified chain-referral recruitment sampling approach, was used to reach unmarried adolescents/youth aged 15-24 in Nairobi, Kenya to measure key FP/C indicators. Seeds were selected and issued with three coupons which they used to invite their peers, male or female, to participate in the study. Referred participants were also given coupons to invite others till sample size was achieved. We report on key implementation parameters following standard RDS reporting recommendations. RESULTS A total of 1674 coupons were issued to generate a sample size of 1354. Coupon return rate was 82.7%. Study participants self-administered most survey questions and missing data was low. Differential enrolment by gender was seen with 56.0% of females recruiting females while 44.0% of males recruited males. In about two months, it was possible to reach the desired sample size using RDS methodology. Implementation challenges included presentation of expired coupons, recruitment of ineligible participants and difficulty recruiting seeds and recruits from affluent neighborhoods. Challenges were consistent with RDS implementation in other settings and populations. RDS can complement standard surveillance/survey approaches, particularly for mobile populations like adolescents/youth.
