Stigma and other correlates of sharing injection equipment among people with HIV in St. Petersburg, Russia. Glob Public Health 2024; 19:2296009. [PMID: 38158724 PMCID: PMC10764055 DOI: 10.1080/17441692.2023.2296009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 12/11/2023] [Indexed: 01/03/2024]
Abstract
Stigma that people with HIV who inject drugs experience negatively impacts HIV and substance use care, but stigma's association with sharing injection equipment is not known. This is a cross-sectional analysis of data from two studies of people with HIV reporting drug injection (N = 319) in St. Petersburg, Russia (September 2018-December 2020). We used logistic regression to examine associations between HIV stigma and substance use stigma scores (categorised into quartiles) and past 30-day equipment sharing, adjusting for demographic and clinical characteristics. Secondary analyses examined associations of arrest history and social support with sharing equipment. Almost half (48.6%) of participants reported sharing injection equipment. Among groups who did and did not share, mean HIV stigma (2.3 vs 2.2) and substance use stigma (32 vs 31) scores were similar. Adjusted analyses detected no significant associations between HIV stigma quartiles (global p-value = 0.85) or substance use stigma quartiles (global p-value = 0.51) and sharing equipment. Neither arrest history nor social support were significantly associated with sharing equipment. In this cohort, sharing injection equipment was common and did not vary based on stigma, arrest history, or social support. To reduce equipment sharing, investments in sterile injection equipment access in Russia should be prioritised over interventions to address stigma.

Abstract
This study evaluated the association between impulsivity and linkage to HIV care among Russians living with HIV recruited from an inpatient narcology hospital. Linking Infectious and Narcology Care (LINC) study participants who completed the Barratt Impulsiveness Scale (BIS) were included in these analyses. The primary independent variable was impulsivity score which was categorized as high impulsivity (BIS score > 71) vs. low impulsivity (BIS score < = 71). The primary outcome, linkage to care post recruitment, was defined as one or more HIV medical care visits at 12-month follow-up. Multiple logistic regression models were used to evaluate the association between high impulsivity and linkage to HIV care controlling for potential confounders. Participants (N = 227) were adults with a mean age of 34 years (SD = 5), and the majority were male (74%). We did not detect a significant association between impulsivity and linkage to HIV care after adjusting for respondents' age, gender, CD4 cell count, and depression score. We also found that substance use and hazardous drinking did not appear to confound the relationship. Although our study was unable to detect an association between impulsivity and linkage to HIV care, it may provide direction for future research exploring the associations between impulsivity and HIV care.

Abstract
Since the beginning of the twenty first century, there has been an intensified political debate about drugs in Russia. The drug problem is now regarded as one of the country's most serious problems and as an issue of top priority for the Russian government. Objectives: The aim of this qualitative study is to explore how illegal drugs are discussed in Russian political discourse. Methods: The material includes an analysis of 177 speeches made in the lower house of the Russian parliament, the Russian State Duma, between 2014 and 2018. The data were analyzed using qualitative content analysis (CDA). Results: In general, the study found that the debate about the drug problem was characterized by consensus, and there were small differences between the Deputy members in their understanding of the problem. Three main understandings of the drug problem were identified: (1) Illegal drugs as an increasing problem in Russia, (2) Drugs as an external threat, and (3) A need for a more repressive drug policy. Conclusion: There was a general consensus about how the drug problem should be regarded among the politicians, with a focus on a war on drugs and an absence of harm reduction ideas.

Abstract
Objective: To determine whether the Linking Infectious and Narcology Care strengths-based case management intervention was more effective than usual care for linking people who inject drugs (PWID) to HIV care and improving HIV outcomes. Design: Two-armed randomized controlled trial. Setting: Participants recruited from a narcology hospital in St. Petersburg, Russia. Participants: A total of 349 HIV-positive PWID not on antiretroviral therapy (ART). Intervention: Strengths-based case management over 6 months. Main outcome measures: Primary outcomes were linkage to HIV care and improved CD4+ cell count. We performed adjusted logistic and linear regression analyses controlling for past HIV care using the intention-to-treat approach. Results: Participants (N = 349) had the following baseline characteristics: 73% male, 12% any past ART use, and median values of 34.0 years of age and CD4+ cell count 311 cells/μl. Within 6 months of enrollment 51% of the intervention group and 31% of controls linked to HIV care (adjusted odds ratio 2.34; 95% confidence interval: 1.49–3.67; P < 0.001). Mean CD4+ cell count at 12 months was 343 and 354 cells/μl in the intervention and control groups, respectively (adjusted ratio of means 1.14; 95% confidence interval: 0.91, 1.42, P = 0.25). Conclusion: The Linking Infectious and Narcology Care strengths-based case management intervention was more effective than usual care in linking Russian PWID to HIV care, but did not improve CD4+ cell count, likely due to low overall ART initiation. Although case management can improve linkage to HIV care, specific approaches to initiate and adhere to ART are needed to improve clinical outcomes (e.g., increased CD4+ cell count) in this population.

Potential impact of implementing and scaling up harm reduction and antiretroviral therapy on HIV prevalence and mortality and overdose deaths among people who inject drugs in two Russian cities: a modelling study. Lancet HIV 2018; 5:e578-e587. [PMID: 30033374 PMCID: PMC6188805 DOI: 10.1016/s2352-3018(18)30168-1] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Revised: 06/22/2018] [Accepted: 06/25/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Most new HIV infections among people who inject drugs (PWID) in eastern Europe and central Asia occur in Russia, where PWID have a high risk of overdose. In Russia, use of opioid agonist therapy (OAT) is prohibited, and coverage of needle and syringe programmes (NSPs) and antiretroviral therapy (ART) is poor. We aimed to assess the effects that scaling up harm reduction (ie, use of OAT and coverage of NSPs) and use of ART might have on HIV incidence and the frequency of fatal overdoses among PWID in two cities in the Ural Federal District and Siberian Federal District, where the prevalence of HIV is high or increasing in PWID. METHODS In this modelling study, we developed a dynamic deterministic model that simulated transmission of HIV through injection drug use and sex among PWID. We calibrated this model to HIV prevalence data among PWID in two Russian cities: Omsk (which has high but increasing prevalence of HIV among PWID) and Ekaterinburg (which has very high but stable prevalence of HIV). The source data were from research studies supported by the Global Fund to Fight AIDS, Tuberculosis, and Malaria and US Centers for Disease Control and Prevention and surveillance studies from WHO and regional AIDS centres. We modelled the effects of no intervention scale-up (no use of harm reduction measures and 30% of HIV-positive PWID receiving ART) versus combinations of scaling up of OAT, receipt of high coverage of NSPs, and use of ART on the incidence of HIV infections, mortality from HIV, and the frequency of fatal overdoses from 2018 to 2028. FINDINGS Without intervention, HIV prevalence among PWID in Omsk could increase from 30% in 2018 to 36% (2·5-97·5 percentile interval 22-52) in 2028 and remain high in Ekaterinburg, estimated at 60% (57-67) in 2028. Scaling up OAT to 50% coverage for a duration of 2 years could prevent 35% of HIV infections and 19% of deaths associated with HIV in Omsk and 20% (11-29) of HIV infections and 10% (4-14) of deaths associated with HIV in Ekaterinburg. Further, this scaling up could prevent 33% of overdose deaths over the next 10 years. Scaling up of NSPs and OAT to 50% coverage and tripling recruitment to ART (reaching about 65% of HIV-positive PWID) could prevent 58% (46-69) of HIV infections and 45% (36-54) of deaths associated with HIV in Omsk and 38% (26-50) of HIV infections and 32% (23-41) of deaths associated with HIV in Ekaterinburg by 2028. INTERPRETATION Legalisation of OAT and increased use of ART and NSPs for PWID are urgently needed to prevent HIV and fatal overdose among PWID in Russia.

The burden of disease in Russia from 1980 to 2016: a systematic analysis for the Global Burden of Disease Study 2016. Lancet 2018; 392:1138-1146. [PMID: 30173906 PMCID: PMC6172188 DOI: 10.1016/s0140-6736(18)31485-5] [Citation(s) in RCA: 48] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2018] [Revised: 06/16/2018] [Accepted: 06/25/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND Over the past few decades, social and economic changes have had substantial effects on health and wellbeing in Russia. We aimed to use data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) to evaluate trends in mortality, causes of death, years lived with disability (YLDs), years of life lost (YLLs), disability-adjusted life-years (DALYs), and associated risk factors in Russia from 1980 to 2016. METHODS We estimated all-cause mortality by use of a multistage modelling process that synthesised data from vital registration systems, surveys, and censuses. A composite measure of health loss due to both fatal and non-fatal disease burden (DALYs) was calculated as the sum of YLLs and YLDs for each age, sex, year, and location. Health progress was evaluated in comparison with patterns of change in similar countries by use of the Socio-demographic Index that was developed for GBD 2016. FINDINGS Following rapid decreases in life expectancy after the collapse of the Soviet Union, life expectancy at birth in Russia improved between 2006 and 2016. The all-cause mortality rate decreased by 16·6% (95% uncertainty interval 9·4-33·8) between 1980 and 2016. This overall decrease encompasses the cycles of sharp increases and plateaus in mortality that occurred before 2005. Child mortality decreased by 57·5% (53·5-61·1) between 2000 and 2016. However, compared with countries at similar Socio-demographic Index levels, rates of mortality and disability in Russia remain high and life expectancy is low. Russian men have a disproportionate burden of disease relative to women. In 2016, 59·2% (55·3-62·6) of mortality in men aged 15-49 years and 46·8% (44·5-49·5) of mortality in women were attributable to behavioural risk factors, including alcohol use, drug use, and smoking. INTERPRETATION Trends in mortality in Russia from 1980 to 2016 might be related to complicated patterns of behavioural risk factors associated with economic and social change, to shifts in disease burden, and to changes in the capacity of and access to health care. Ongoing mortality and disability from causes and risks amenable to health-care interventions and behaviour modifications present opportunities to continue to improve the wellbeing of Russian citizens.

Abstract
Estimating the size of stigmatized, hidden, or hard-to-reach populations is a major problem in epidemiology, demography, and public health research. Capture-recapture and multiplier methods are standard tools for inference of hidden population sizes, but they require random sampling of target population members, which is rarely possible. Respondent-driven sampling (RDS) is a survey method for hidden populations that relies on social link tracing. The RDS recruitment process is designed to spread through the social network connecting members of the target population. In this paper, we show how to use network data revealed by RDS to estimate hidden population size. The key insight is that the recruitment chain, timing of recruitments, and network degrees of recruited subjects provide information about the number of individuals belonging to the target population who are not yet in the sample. We use a computationally efficient Bayesian method to integrate over the missing edges in the subgraph of recruited individuals. We validate the method using simulated data and apply the technique to estimate the number of people who inject drugs in St. Petersburg, Russia.

Abstract
BACKGROUND Russia and Eastern Europe have one of the fastest growing HIV epidemics in the world. While countries in this region have implemented HIV testing within addiction treatment systems, linkage to HIV care from these settings is not yet standard practice. The Linking Infectious and Narcology Care (LINC) intervention utilized peer-led strengths-based case management to motivate HIV-infected patients in addiction treatment to obtain HIV care. This paper describes the protocol of a randomized controlled trial evaluating the effectiveness of the LINC intervention in St. Petersburg, Russia. METHODS/DESIGN Participants (n = 349) were recruited from the inpatient wards at the City Addiction Hospital in St. Petersburg, Russia. After completing a baseline assessment, participants were randomly assigned to receive either the LINC intervention or standard of care. Participants returned for research assessments 6 and 12 months post-baseline. Primary outcomes were assessed via chart review at HIV treatment locations. DISCUSSION LINC holds the potential to offer an effective approach to coordinating HIV care for people who inject drugs in Russia. The LINC intervention utilizes existing systems of care in Russia, minimizing adoption of substantial infrastructure for implementation. Trial Registration NCT01612455.

Abstract
Russian Federation’s (RF) HIV epidemic is the fastest growing of any country. This study explores factors associated with high HIV risk behavior in tuberculosis (TB) patients with alcohol use disorders in Tomsk, RF. This analysis was nested within the Integrated Management of Physician-delivered Alcohol Care for TB Patients (IMPACT, trial number NCT00675961) randomized controlled study of integrating alcohol treatment into TB treatment in Tomsk. Demographics, HIV risk behavior (defined as participant report of high-risk intravenous drug use and/or multiple sexual partners with inconsistent condom use in the last six months), clinical data, alcohol use, depression and psychosocial factors were collected from 196 participants (161 male and 35 female) at baseline. Forty-six participants (23.5%) endorsed HIV risk behavior at baseline. Incarceration history(Odds Ratio (OR)3.93, 95% confidence interval (CI) 1.95, 7.95), age under 41 (OR:2.97, CI:1.46, 6.04), drug addiction(OR: 3.60 CI:1.10, 11.77), history of a sexually transmitted disease(STD)(OR 2.00 CI:1.02, 3.90), low social capital (OR:2.81 CI:0.99, 8.03) and heavier alcohol use (OR:2.56 CI: 1.02, 6.46) were significantly more likely to be associated with HIV risk behavior at baseline. In adjusted analysis, age under 41(OR: 4.93, CI: 2.10, 11.58), incarceration history(OR: 3.56 CI:1.55, 8.17) and STD history (OR: 3.48, CI: 1.5, 8.10) continued to be significantly associated with HIV risk behavior. Understanding HIV transmission dynamics in Russia remains an urgent priority to inform strategies to address the epidemic. Larger studies addressing sex differences in risks and barriers to protective behavior are needed.

This study was designed to assess the characteristics of krokodile injectors, a recent phenomenon in Ukraine, and HIV-related risk factors among people who inject drugs (PWID). In three Ukraine cities, Odessa, Donetsk and Nikolayev, 550 PWID were recruited between December 2012 and October 2013 using modified targeted sampling methods. The sample averaged 31 years of age and they had been injecting for over 12 years. Overall, 39 % tested positive for HIV, including 45 % of krokodile injectors. In the past 30 days, 25 % reported injecting krokodile. Those who injected krokodile injected more frequently (p < 0.001) and they injected more often with others (p = 0.005). Despite knowing their HIV status to be positive, krokodile users did not reduce their injection frequency, indeed, they injected as much as 85 % (p = 0.016) more frequently than those who did not know their HIV status or thought they were negative. This behavior was not seen in non-krokodile using PWID. Although only a small sample of knowledgeable HIV positive krokodile users was available (N = 12), this suggests that krokodile users may disregard their HIV status more so than nonkrokodile users. In spite of widespread knowledge of its harmful physical consequences, a growing number of PWID are turning to injecting krokodile in Ukraine. Given the recency of krokodile use the country, the associated higher frequency of injecting, a propensity to inject more often with others, and what could be a unique level of disregard of HIV among krokodile users, HIV incidence could increase in future years.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2015; 25:1163-73. [PMID: 25449056 DOI: 10.1016/j.drugpo.2014.09.013] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2014] [Revised: 09/24/2014] [Accepted: 09/26/2014] [Indexed: 01/01/2023]
Abstract
BACKGROUND Although there is evidence of the effectiveness of needle and syringe programme (NSP), opioid substitution therapy (OST) and antiretroviral therapy (ART) in reducing HIV prevalence, most Central and Eastern European sub-regions still have low or no coverage of most or all of these interventions. METHODS We conducted a modelling analysis to consider the potential impact on HIV incidence and prevalence of OST, NSP and ART in three illustrative epidemic scenarios: Russia (St. Petersburg); Estonia (Tallinn) and Tajikistan (Dushanbe). For each intervention, we consider the coverage needed of each intervention separately or in combination to: (1) achieve a 30% or 50% relative reduction in HIV incidence or prevalence over 10 years; and (2) reduce HIV incidence to below 1% or HIV prevalence below 10% after 20 years. A sensitivity analysis for St. Petersburg considered the implications of greater on no risk heterogeneity, none or more sexual HIV transmission, like-with-like mixing, different injecting cessation rates and assuming a lower HIV acute phase cofactor. RESULTS For St. Petersburg, when OST, NSP and ART are combined, only 14% coverage of each intervention is required to achieve a 30% reduction in HIV incidence over 10 years. Similar findings are obtained for Tallinn and Dushanbe. In order to achieve the same reductions in HIV prevalence over 10 years, over double the coverage level is required relative to what was needed to achieve the same reduction in HIV incidence in that setting. To either reduce HIV incidence to less than 1% or HIV prevalence to less than 10% over 20 years, with all interventions combined, projections suggest that very high coverage levels of 74–85% are generally required for the higher prevalence settings of Tallinn and St. Petersburg, whereas lower coverage levels (23–34%) are needed in Dushanbe. Coverage requirements are robust to increased sexual HIV transmission, risk heterogeneity and like-with-like mixing, as well as to assuming a lower HIV acute phase cofactor or different injecting cessation rate. CONCLUSION The projections suggest that high but achievable coverage levels of NSP can result in large decreases (30%) in HIV incidence in settings with high HIV prevalence among PWID. Required coverage levels are much lower when interventions are combined or in lower prevalence settings. However, even when all three interventions are combined, the targets of reducing HIV incidence to less than 1% or prevalence to less than 10% in 20 years may be hard to achieve except in lower prevalence settings.

Abstract
AIMS This study assessed the effectiveness of HERMITAGE (HIV's Evolution in Russia-Mitigating Infection Transmission and Alcoholism in a Growing Epidemic), an adapted secondary HIV prevention intervention, compared with an attention control condition in decreasing sexually transmitted infections (STIs) and sex and drug risk behaviors among Russian HIV-infected heavy drinkers. DESIGN We conducted a single-blinded, two-armed, randomized controlled trial with 12-month follow-up. SETTING The study was conducted in St Petersburg, Russia. Participants were recruited from four HIV and addiction clinical sites. The intervention was conducted at Botkin Infectious Disease Hospital. PARTICIPANTS HIV-infected individuals with past 6-month risky sex and heavy alcohol consumption (n = 700) were randomized to the HERMITAGE intervention (n = 350) or an attention control condition (n = 350). INTERVENTION A Healthy Relationships Intervention stressing disclosure of HIV serostatus and condom use, adapted for a Russian clinical setting with two individual sessions and three small group sessions. MEASUREMENTS The primary outcome was incident STI by laboratory test at 12-month follow-up. Secondary outcomes included change in unprotected sex and several alcohol and injection drug use (IDU) variables. FINDINGS Participants had the following baseline characteristics: 59.3% male, mean age 30.1, 60.4% past year IDU, 15.4% prevalent STI and mean CD4 cell count 413.3/μl. Assessment occurred among 75 and 71% of participants at 6 and 12 months, respectively. STIs occurred in 20 subjects (8.1%) in the intervention group and 28 subjects (12.0%) in the control group at 12-month follow-up; logistic regression analyses found no significant difference between groups (adjusted odds ratio 0.63; 95% confidence interval = 0.34-1.18; P = 0.15). Both groups decreased unsafe behaviors, although no significant differences were found between groups. CONCLUSIONS The HERMITAGE HIV risk reduction intervention does not appear to reduce sexually transmitted infections and HIV risk behaviors in Russian HIV-infected heavy drinkers compared with attention controls.

Abstract
Background Behavioural surveillance among people who inject drugs (PWID) and testing for hepatitis C virus (HCV) and HIV is needed to understand the scope of both epidemics in at-risk populations and to suggest steps to improve their health. Methods PWID were recruited using respondent-driven sampling (RDS) in eight Russian cities. A standardized survey was administered to collect sociodemographic and behavioral information. Blood specimens were obtained for serological testing for HCV and HIV-1. Data across the eight sites were pooled to identify individual-, network-, and city-level factors associated with positive HCV serostatus. Results Among 2,596 PWID participating in the study, 1,837 tested positive for HCV (71%). The sample was 73% male and the mean age was 28. Very few PWID reported regular contact with harm reduction programs. Factors associated with testing positive for HCV were longer duration of injection drug use, testing positive for HIV-1, sharing non-syringe injection paraphernalia and water for rinsing syringes, and larger social network size. Factors negatively associated with HCV-positive serostatus were injecting with a used syringe and two city-level factors: longer mean RDS recruitment chain in a city and higher levels of injecting stimulants. Conclusions HCV prevalence in all eight Russian cities is at the higher end of the range of HCV prevalence among PWID in Europe, which provides evidence that more resources, better prevention programs, and accelerated treatment targeting PWID are needed to control the HCV epidemic.

Abstract
Overdoses and HIV infection are common among Russians who inject drugs, yet risk factors have not been studied. We analyzed baseline data of 294 participants with 30-day injection drug use from an HIV secondary prevention trial for persons reporting "heavy" alcohol use (National Institute on Alcohol Abuse and Alcoholism [NIAAA] risky drinking definition) and risky sex in the past 6 months. The outcome was any self-reported overdose in the previous 3 months. We examined demographic, HIV-related, criminal justice, mental health, substance use, and injection risk factors. Participants' characteristics included median age 29 years, 117/294 (40%) female, and median CD4 cell count 345/µl. Over three quarters 223/294 (76%) reported a history of overdose and 47/294 (16%) reported overdose in the past 3 months. Past month injection frequency (adjusted odds ratio [AOR] 4.77, 95% confidence interval [CI]: 1.63-14.0 highest vs. lowest quartile; AOR 3.58, 95% CI: 1.20-10.69 second highest vs. lowest quartile) and anti-retroviral therapy (ART) at time of interview (AOR 3.96 95% CI: 1.33-11.83) were associated with 3-month overdose. Nonfatal overdose among HIV-infected Russians who inject drugs is common. Risk factors include injection frequency and anti-retroviral therapy (ART), which warrant further study. Overdose prevention efforts are needed among HIV-infected Russians who inject drugs.

Abstract
While the global HIV incidence dropped about 20 % in the past 10 years, HIV incidences among people who inject drugs (PWID) in Asia and Europe continue to increase and to account for high proportions of new HIV infections among PWID globally. Great changes have been observed in this region, such as progressing from rejection to acceptance of harm reduction strategies in Asian countries, but no such change has occurred in Eastern European countries. China has quickly scaled up harm reduction activities nationwide, resulting in the decline of HIV incidence and HIV prevalence among PWID since 2006. However, insufficient scaling up of harm reduction programs in other countries has failed to slow down their HIV epidemics. In Eastern European countries where the spread of HIV among PWID is the most severe, only about 15 % of funding for harm reduction programs are from domestic sources. Strong political and financial commitment from countries in this region is urgently needed to quickly scale up evidence-based harm reduction strategies in order to prevent the HIV epidemic from spreading rapidly from PWID to the heterosexual general population.

Abstract
BACKGROUND HIV infection is prevalent among drug injectors in St. Petersburg and their non-injecting heterosexual partners (PIDUs). There are fears that sexual transmission of HIV from IDUs to PIDUs may portend a self-sustaining, heterosexual epidemic in Russia. METHODS Our model combines a network model of sexual partnerships of IDUs and non-IDUs to represent sexual transmission of HIV and a deterministic model for parenteral transmission among IDUs. Behavioural parameters were obtained from a survey of St. Petersburg IDUs and their sexual partners. We based our model fits on two scenarios for PIDU prevalence in 2006 (5.6% and 15.1%, calculated excluding and including HCV co-infected PIDUs respectively) and compared predictions for the general population HIV prevalence. RESULTS Results indicate that sexual transmission could sustain a non-IDU HIV epidemic. The model indicates that general population prevalence may be greater than current estimates imply. Parenteral transmission drives the epidemic and the PIDU bridge population plays a crucial role transferring infection to non-IDUs. The model indicates that the high PIDU prevalence is improbable because of the high risk behaviour this implies; the lower prevalence is possible. CONCLUSION The model implies that transmission through PIDUs will sustain a heterosexual epidemic, if prevalence among IDUs and PIDUs is as high as survey data suggest. We postulate that current estimates of population prevalence underestimate the extent of the HIV epidemic because they are based on the number of registered cases only. Curtailing transmission among injectors and PIDUs will be vital in controlling heterosexual transmission.

Abstract
Despite HIV prevention efforts over the past 10 years in Odessa, Ukraine, HIV rates among injection drug users (IDUs) remain high. We explored whether IDUs' experiences with the police and court system in Odessa were associated with HIV serostatus, after controlling for other factors. Qualitative methods, including semi-structured interviews with the police and members of court (N = 19), and focus groups with IDUs (N = 42), were employed to aid in developing a survey instrument for a larger quantitative phase and to assist in interpreting the findings from the quantitative phase, which included 200 participants who were interviewed and tested for HIV. Overall, 55 % tested positive for HIV. Negative experiences with the police were noted by 86 % and included having preloaded syringes taken (66 %), rushed injections due to fear of the police (57 %), police planting drugs (18 %), paying police to avoid arrest (61 %) and threatened by the police to inform on other IDUs (23 %). HIV positive participants were more likely than those who were negative to report these experiences. In a multiple logistic regression, the most significant correlate of HIV infection was rushed injections due to fear of the police. Police actions in Odessa may be contributing to the continued escalation of HIV among IDUs, underscoring the need for structural interventions.

Abstract
Background The HIV epidemic in Russia is concentrated among injection drug users (IDUs). This is especially true for St. Petersburg where high HIV incidence persists among the city’s estimated 80,000 IDUs. Although sterile syringes are legally available, access for IDUs may be hampered. To explore the feasibility of using pharmacies to expand syringe access and provide other prevention services to IDUs, we investigated the current access to sterile syringes at the pharmacies and the correlation between pharmacy density and HIV prevalence in St. Petersburg. Methods 965 pharmacies citywide were mapped, classified by ownership type, and the association between pharmacy density and HIV prevalence at the district level was tested. We selected two districts among the 18 districts – one central and one peripheral – that represented two major types of city districts and contacted all operating pharmacies by phone to inquire if they stocked syringes and obtained details about their stock. Qualitative interviews with 26 IDUs provided data regarding syringe access in pharmacies and were used to formulate hypotheses for the pharmacy syringe purchase test wherein research staff attempted to purchase syringes in all pharmacies in the two districts. Results No correlation was found between the density of pharmacies and HIV prevalence at the district level. Of 108 operating pharmacies, 38 (35%) did not sell syringes of the types used by IDUs; of these, half stocked but refused to sell syringes to research staff, and the other half did not stock syringes at all. Overall 70 (65%) of the pharmacies did sell syringes; of these, 49 pharmacies sold single syringes without any restrictions and 21 offered packages of ten. Conclusions Trainings for pharmacists need to be conducted to reduce negative attitudes towards IDUs and increase pharmacists’ willingness to sell syringes. At a structural level, access to safe injection supplies for IDUs could be increased by including syringes in the federal list of mandatory medical products sold by pharmacies.

Abstract
Substance use is highly prevalent among people living with HIV/AIDS, is often comorbid with other mental health problems, related to poor HIV medical outcomes, and, is associated with poor medication and treatment adherence. The current review reports on the recent state of the literature in terms of substance use and its relation to HIV medication and treatment adherence, and offers recommendations for advancing treatment and secondary HIV prevention efforts. Identifying substance users within HIV primary care and developing, evaluating, and refining integrative substance use-mental health-adherence interventions may be clinically important targets for effective disease management and may contribute to secondary HIV prevention efforts.

Abstract
OBJECTIVES We evaluated the effects of an individual intervention versus a network intervention on HIV-related injection and sexual risk behaviors among street-recruited opiate injection drug users in 5 Ukraine cities. METHODS Between 2004 and 2006, 722 opiate injection drug users were recruited to participate in interventions that were either individually based or based on a social network model in which peer educators intervened with their network members. Audio computer-assisted self-interview techniques were used to interview participants at baseline and follow-up. RESULTS Multiple logistic analyses controlling for baseline injection and sexual risks revealed that both peer educators and network members in the network intervention reduced injection-related risk behaviors significantly more than did those in the individually based intervention and that peer educators increased condom use significantly more than did those in the individual intervention. Individual intervention participants, however, showed significantly greater improvements than did network members with respect to reductions in sexual risk behaviors. CONCLUSIONS Social network interventions may be more effective than individually based interventions in changing injection risk behaviors among both peer educators and network members. The effectiveness of network interventions in changing sexual risk behaviors is less clear, probably owing to network composition and inhibitions regarding discussing sexual risk behaviors.

Abstract
The idea that HIV and AIDS gets too much attention and funding emerged in 2008 with a call to end 'AIDS exceptionalism.' This article outlines a short history of AIDS exceptionalism - the idea that HIV and AIDS require a response above and beyond 'normal' health interventions and is privileged in terms of attention and resources when compared with other diseases - and the reasons for the backlash to this idea. We argue that in some settings HIV and AIDS must be treated as exceptional. These are the hyperendemic countries of southern Africa, where HIV epidemics have shown substantial and lasting demographic and social impact, and parts of Eastern Europe where the epidemic is augmenting troubling demographic changes, such as declines in fertility rates and population growth, and impacting society in nuanced ways. Also included are resource-poor settings, mostly in Africa, where the combination of the high number of HIV infections and the cost of treatment have created issues concerning donor dependency and sustainable responses. An HIV epidemic must be seen as a long-wave event, with complex challenges to both HIV prevention and treatment responses. The article reviews the available data and literature to provide evidence for our arguments. We conclude that the perception that AIDS exceptionalism is outdated ignores the complexity of different HIV epidemics and obfuscates the challenges to effective responses.

Abstract
BACKGROUND Russia faces a worsening IDU/HIV epidemic. This paper examines the social and economic characteristics of injecting drug users in two cities in Russia and compares this with the general population to explore their social and economic needs and the wider implications of the epidemic for the economy and society. METHODS A cross sectional survey of 711 IDUs in two Russian cities (Volgograd and Barnaul) recruited by a modified chain referral sampling method. Respondents were asked about their education, work, living conditions, expenditure on goods and services and livelihoods. Their characteristics were compared with a random sample of the general population. RESULTS There are a number of characteristics, in which IDUs do not differ systematically from the general population. They have general education; live in the towns where they were born; and their monthly income is comparable with the Russian average. However, IDUs are more likely to have a vocational qualification than a university degree; less likely to have a permanent job; and those employed are skilled manual rather than professional workers. IDUs are less likely to be officially married and more likely to be living with their parents or on their own. The majority rely on financial help from relatives or friends; and much of their income is from illegal or semi-legal activities. CONCLUSION IDUs are not atypical or marginal to the Russian economy and society. However, their drug-dependency and related life-style make them particularly vulnerable to the impact of poverty, violence and social insecurity. A failure to effectively control the dual IDU/HIV epidemic can have a significant negative impact on the Russian labour force, health and social costs and overall economy.

Abstract
AIMS To review the evidence on the effectiveness of harm reduction interventions involving the provision of sterile injecting equipment in the prevention of hepatitis C virus (HCV) and human immunodeficiency virus (HIV) transmission among injecting drug users (IDUs). The interventions assessed were needle and syringe programmes (NSP), alternative modes of needle/syringe provision (pharmacies, vending machines and outreach) and the provision of injecting equipment other than needles/syringes. METHODS Systematic searches of the English language literature to March 2007 were undertaken to identify systematic, narrative or meta-analytical reviews (also known as a review of reviews) of the impact of interventions on HCV transmission, HIV transmission or injecting risk behaviour (IRB). Critical appraisal criteria classified the reviews as either high quality ('core') or supplementary: a framework based on the quality of reviews, the reviewers' conclusions and the designs/findings of the primary studies was used to derive evidence statements. RESULTS Three core and two supplementary reviews of injecting equipment interventions were identified. According to the proposed framework, this study found (a) insufficient evidence to conclude that any of the interventions are effective in preventing HCV transmission; (b) tentative evidence to support the effectiveness of NSP in preventing HIV transmission; (c) sufficient evidence to support the effectiveness of NSP (and tentative evidence of an additional impact of pharmacy NSP) in reducing self-reported IRB; and (d) little to no evidence on vending machines, outreach or providing other injecting equipment in relation to any of the outcomes. CONCLUSIONS The evidence is weaker than given credit for in the literature. The lack of evidence for effectiveness of NSP vis-à-vis biological outcomes (HCV and HIV incidence/prevalence) reflects the limitations of studies that have been undertaken to investigate these associations. Particularly for HCV, low levels of IRB may be insufficient to reduce high levels of transmission. New studies are required to identify the intervention coverage necessary to achieve sustained changes in blood-borne virus transmission.

Abstract
AIMS To understand the epidemiology and transmission patterns of hepatitis C virus (HCV), the predominant blood borne-pathogen infecting injection drug users (IDUs), in a part of the former Soviet Union. DESIGN Cross-sectional respondent-driven sample of IDUs. SETTING St Petersburg, Russia. PARTICIPANTS A total of 387 IDUs were recruited in late 2005 and throughout 2006. MEASUREMENTS Participants were surveyed to collect demographic, medical and both general and dyad-specific drug injection and sexual behaviors. A blood sample was collected to detect antibodies to hepatitis C and to amplify viral RNA for molecular analysis. The molecular data, including genotypes, were analyzed spatially and linkage patterns were compared to the social linkages obtained by respondent-driven sampling (RDS) for chains of respondents and among the injection dyads. FINDINGS HCV infection was all but ubiquitous: 94.6% of IDUs were HCV-seropositive. Among the 209 viral sequences amplified, genotype 3a predominated (n = 119, 56.9%), followed by 1b (n = 61, 29.2%) and 1a (n = 25, 11.9%). There was no significant clustering of genotypes spatially. Neither genotypes nor closely related sequences were clustered within RDS chains. Analysis of HCV sequences from dyads failed to find associations of genotype or sequence homology within pairs. CONCLUSIONS Genotyping reveals that there have been at least five unique introductions of HCV genotypes into the IDU community in St Petersburg. Analysis of prevalent infections does not appear to correlate with the social networks of IDUs, suggesting that simple approaches to link these networks to prevalent infections, rather than incident transmission, will not prove meaningful. On a more positive note, the majority of IDUs are infected with 3a genotype that is associated with sustained virological response to antiviral therapy.

Abstract
AIMS To assess the effectiveness of a brief human immunodeficiency virus (HIV) testing and counseling intervention compared to a more time-consuming and expensive street-based intervention with injection drug users (IDUs). DESIGN Cross-over experimental design in which 900 IDUs were recruited, followed by a 'wash-out' period with no recruitment, a reversal of intervention assignment areas and an additional recruitment of 900 IDUs with baseline and 6-month follow-up assessments. SETTING Kiev, Odessa and Makeevka/Donesk Ukraine. PARTICIPANTS A total of 1798 IDUs. MEASUREMENTS HIV testing and audio computer-assisted self-interview (ACASI) data on socio-demographics, drug use and injection and sex-related risk behaviors. FINDINGS Participants in both conditions reduced their injection and sex risks significantly; however, there was little difference in outcomes between conditions. IDUs who knew they were HIV-infected at baseline were significantly more likely to practice safe sex than those unaware or HIV-negative; those who first learned that they were infected at baseline changed their safe sex practices significantly more than those who already knew that they were infected at baseline and those who were HIV-negative. Younger IDUs and those injecting for a shorter period of time reported higher injection and sex risk behaviors following interventions. CONCLUSIONS Awareness of HIV infection by street-recruited drug injectors is associated with reduced sex risks. Additional interventions are required for younger IDUs and those injecting for shorter periods of time.

Abstract
Background The HIV epidemic in Russia has been driven by the unsafe injection of drugs, predominantly heroin and the ephedrine derived psychostimulants. Understanding differences in HIV risk behaviors among injectors associated with different substances has important implications for prevention programs. Methods We examined behaviors associated with HIV risk among 900 IDUs who inject heroin, psychostimulants, or multiple substances in 2002. Study participants completed screening questionnaires that provided data on sociodemographics, drug use, place of residence and injection- and sex-related HIV risk behaviors. HIV testing was performed and prevalence was modeled using general estimating equation (GEE) analysis. Individuals were clustered by neighborhood and disaggregated into three drug use categories: Heroin Only Users, Stimulant Only Users, and Mixed Drug Users. Results Among Heroin Only Users, younger age, front/backloading of syringes, sharing cotton and cookers were all significant predictors of HIV infection. In contrast, sharing needles and rinse water were significant among the Stimulant Only Users. The Mixed Drug Use group was similar to the Heroin Only Users with age, front/back loading, and sharing cotton significantly associated with HIV infection. These differences became apparent only when neighborhood of residence was included in models run using GEE. Conclusion The type of drug injected was associated with distinct behavioral risks. Risks specific to Stimulant Only Users appeared related to direct syringe sharing. The risks specific to the other two groups are common to the process of sharing drugs in preparation to injecting. Across the board, IDUs could profit from prevention education that emphasizes both access to clean syringes and preparing and apportioning drug with these clean syringes. However, attention to neighborhood differences might improve the intervention impact for injectors who favor different drugs.

The potential for bridging of HIV transmission in the Russian Federation: sex risk behaviors and HIV prevalence among drug users (DUs) and their non-DU sex partners. J Urban Health 2009; 86 Suppl 1:131-43.

Abstract
The HIV epidemic that began in Russia in the mid-1990s has been concentrated mostly among drug users (DUs). Recent evidence of increasing HIV cases among non-DUs attributed to sexual behavior raises potential concern about a more generalized epidemic. The purpose of this analysis is to examine the potential for HIV transmission from DUs to their non-DU sex partners. Analyses are conducted using data collected during 2005-2008 in St. Petersburg, Russia. A total of 631 DUs were recruited into the sample with an HIV prevalence of 45%. A majority (84%) of DUs reported being sexually active in the past 6 months, and the DU status of their sex partners was reported as follows: 54% DU, 40% non-DU, and 6% unknown DU status. In 41% of partnerships with an HIV-negative or unknown status partner not known to be DU (potential bridging partnerships), the last reported intercourse was unprotected. Female DUs with potential bridging partnerships were more likely than male DUs to be younger and report homelessness and to have multiple or new sex partners. Many non-DU sex partners of DUs enrolled in the study reported new sex partners in the past 6 months (66%), unprotected intercourse at last sex (60%), and multiple sex partners in the past 6 months (48%). HIV prevalence in this group was 15% (eight out of 53). The high prevalence of HIV among DUs, their sexual contact with non-DUs, and the high-risk sexual behaviors of this potential bridging population together indicate the real potential for an increasingly generalized epidemic. The degree to which there will be further transmission from non-DU sex partners of DUs who exhibit high levels of sex risk behaviors to other non-DU sex partners deserves further study.

Abstract
OBJECTIVE To describe and compare sexual and injecting risk behaviours and sexually transmitted infections (STI), hepatitis C virus (HCV) and HIV prevalence in injecting drug users (IDU) in six districts in three states of India: Manipur, Nagaland, and Maharashtra. METHOD The respondent-driven sample consisted of 2075 IDU. Consenting participants were administered a structured questionnaire and samples of blood and urine were collected to test for HIV and STI. Data were analysed using RDSAT. RESULTS In two districts in Manipur, 77 and 98% of IDU injected heroin, whereas the main injecting drug in Nagaland was dextropropoxyphene (99%). In Mumbai/Thane, Maharashtra, the majority of respondents reported using chlorpheniramine (87%) and heroin (99%). In all districts, almost half of IDU reported generally sharing needles and syringes; consistent condom use with non-paid female partners was also low. Approximately one-quarter of IDU in Mumbai/Thane visited a paid partner in the past year. IDU with reactive syphilis serology were higher in Nagaland (7 and 19%) than in Manipur and Maharashtra. HIV in two districts of Manipur (23%, 32%) and Mumbai/Thane (16%) was greater than Nagaland (<2%). HCV prevalence was more than 50% in Mumbai/Thane and Manipur. CONCLUSION Irrespective of regional differences, high-risk behaviour of needle sharing and low condom use makes IDU a critical subpopulation for HIV prevention interventions. Interventions need to address the differing drug use patterns in the regions and transmission prevention among non-paid regular and casual female partners of IDU in the northeast districts and paid female partners in Mumbai/Thane.

Abstract
Gender shapes the experience of drug use and its associated risks. In most parts of the world, however, harm reduction and drug treatment programmes that tailor their services to meet women's needs are rare or nonexistent. Many existing services inadvertently exclude women, and discriminatory policies and social stigma drive women drug users from care and expose them to human rights abuses. Women drug users often provide sex in exchange for housing, sustenance and protection, suffer violence from sexual partners and practise unsafe sex. This paper, drawing upon evidence from existing studies, examines ways in which gender-related factors can increase women drug users' vulnerability and decrease their access to harm reduction, drug treatment and sexual and reproductive health services. It recommends designing services with low-threshold access for women drug users that help them to become more independent, involving the women in designing services and policies, making programmes available for mothers, incorporating sexual and reproductive health into harm reduction services, providing gender-sensitive drug treatment and integrated harm reduction programmes for drug-using sex workers, connecting with domestic violence and rape prevention services and educating mainstream providers. Overall, investigating the circumstances women drug users face will help to formulate policies and programmes that better serve women who use drugs.

Abstract
OBJECTIVES In the Russian Federation, large sectors of the population regularly undergo mandatory occupational screening for sexually transmitted infections (STIs). Objectives of our study were to determine the prevalence of syphilis and gonorrhea in the screened occupational groups in Moscow and to conduct a cost-effectiveness evaluation of the occupational screening program. STUDY DESIGN Serum samples from 4 main occupational groups (food handlers and other food industry workers, market salespersons, education and health care providers, and hotel and other public utility workers) were tested for syphilis and gonorrhea. We conducted a cost-effectiveness analysis (in 2003 rubles) of the screening program using decision analysis models. RESULTS In the total sample of 1000 study participants, overall prevalence for syphilis was 1.2% with the highest rate in market salespersons (4.4%) and for gonorrhea 0.3%. The incremental cost per case of STI treated was 8409 rubles ($252) for syphilis screening (compared with no screening) with higher incremental costs associated with expanding the program to include gonorrhea screening. The relatively low STI prevalence in the screened groups and the poor performance of the diagnostic tests used were important factors in the estimated cost-effectiveness of occupation-based screening. CONCLUSIONS Modifications to occupation-based screening, including an increased focus on higher risk population and the adoption of more current diagnostic technologies, could help to use prevention resources more effectively.

Abstract
This study was designed to assess differences in drug and sex-related risk behaviors between injectors of opiates only, opiate/sedative mix only and stimulants only. Participants were current out-of-treatment injection drug users (IDUs), unaware of their HIV status, recruited through street outreach in Kiev, Odessa and Makeevka/Donetsk, Ukraine. Overall, 22% tested positive for HIV, including 39% among opiate/sedative injectors, 19% among opiate injectors and 17% among stimulant injectors. Despite these differences, stimulant injectors were at higher risk than other IDUs in sharing a used needle/syringe, always injecting with others, injecting a drug solution drawn from a common container, having an IDU sex partner, not using condoms during vaginal or anal sex and on composite measures of injection and sex risks. After controlling for age differences, stimulant injectors remained at higher risk in their needle and sex risk behaviors. Without intervention, it is likely that HIV will increase among stimulant injectors.

Abstract
INTRODUCTION The HIV/AIDS epidemic in St Petersburg, as in much of Russia, is concentrated among injection drug users (IDU) in whom prevalence reached 30% in 2003. Understanding the dynamics of the epidemic is important in developing appropriate responses in the resource-constrained context of Russian cities such as St Petersburg. METHODS IDU were contacted and screened to create a seronegative cohort for prevention and vaccine studies. At screening, individuals provided sociodemographic, drug use, and injection and sex-related risk behavior data. Seronegative individuals who enrolled in the cohort were followed for one year and tested for HIV semiannually. Residential addresses were entered into a geographical information system programme and analysed for spatial clustering using Moran's I and nearest-neighbor analysis. RESULTS We mapped 788 of the 900 study participants to discrete locations within St Petersburg; 236 (29.9%) were HIV seropositive at baseline. Although there was no clustering of the study population as a whole, HIV-infected individuals were tightly clustered and prevalence co-clustered with high frequency of heroin injection, receptive syringe sharing, being younger than 24 years, and living with parents. These clusters were restricted to 5% of populated areas of the city. We mapped 18 of 20 incident cases detected among the cohort, and more than half were located within or adjacent to the clusters. INTERPRETATION Spatial analysis identified linkages between disease prevalence and risky injection behaviors that were not evident using traditional epidemiological analysis. The analysis also identified where resources might be allocated geographically for maximum impact in slowing the HIV epidemic among IDU.

Abstract
Europe is currently experiencing the fastest rate of growth of HIV of any region of the world. An analysis of policy and health system responses to the HIV epidemic in Europe and central Asia (hereafter referred to as Europe) over the last 25 years reveals considerable heterogeneity. In general, while noting hazards of broad generalisations and the differences that exist across countries in a particular grouping, effective policies to control HIV have been implemented more widely in western than in central and eastern Europe. However, the evidence suggests persistence of inequalities in access to preventive and treatment services, with those at highest risk, such as commercial sex workers, prisoners, intravenous drug users, and migrants often particularly disadvantaged, despite many targeted programmes. Responses in individual countries, especially in the early stages of the epidemic, were influenced by specific cultural and political factors. Strong leadership and active involvement by civil society organisations emerge as important factors for success but also a limiting factor to the response observed in eastern Europe, where civil society or NGO culture is weak as compared to western Europe. Scaling up of effective responses in many countries in eastern Europe will be challenging-where increased financial resources will have to be accompanied by broader changes to health system organization with greater involvement of the civil society in planning and delivery of client-focused services.

Abstract
OBJECTIVE To assess gender differences in drug and sex risk behaviors and evaluate predictors of HIV-related sex risk behaviors among heterosexual injection drug users (IDUs) in Ukraine. DESIGN Street-recruited IDUs from Kiev, Odessa, and Makeevka/Donesk, Ukraine. METHODS From June 2004 through November 2006, outreach workers recruited 1557 IDUs, including 526 from Kiev, 494 from Odessa, and 537 from Makeevka/Donesk. Participants were administered a standardized computer-assisted interview assessing HIV-related drug and sex risk behaviors, self-efficacy for practicing safe sex, and HIV knowledge. RESULTS Overall, 80% of the participants were sexually active in the 30-day period before their interview. They also engaged in high-risk sex behaviors during this brief 30-day window: 53% reported anal or vaginal sex without a condom, 27% had sex with more than 1 partner, 41% had an IDU sex partner, and 37% had an HIV-positive sex partner or a partner whose HIV status they did not know. Overall, women were at higher risk than men and were more likely to have been told they were HIV-positive. CONCLUSION The extremely high HIV prevalence rate in Ukraine and in this cohort, combined with their recent high-risk sex behaviors, forecasts not only a continuance of the epidemic in the region but an escalation.

Abstract
OBJECTIVES to examine attitudes of Russian policy-makers and HIV stakeholders towards harm reduction (HR) scale up, focusing on the factors constraining the scale-up process. METHODS Semi-structured interviews with representatives of 58 government and non-governmental organisations involved in HIV policies and programmes in Volgograd Region, Russian Federation. RESULTS We found a considerable diversity of opinion on HR scale-up and suggest that Russia is experiencing the situation of power parity between HR supporters and opponents with many stakeholders being indecisive or cautious to express their views. We identified six main factors which constrain policy decisions in favour of HR scale-up: insufficient financial resources; lack of information on HR effectiveness; perception of HR as being culturally unacceptable; reluctance of IDUs to use the services; opposition from law enforcement agencies and the Russian Church; and unclear legal regulations. We demonstrate a complex interplay between these factors, policy-makers' attitudes and their choices on HR scale-up. CONCLUSIONS A number of actions are needed to achieve a successful scale-up of HR programmes in Russia and similar political contexts: (i) a strategic approach to HR advocacy, targeting neutral and indecisive stakeholders; (ii) more systematic evidence on HR effectiveness and cost-effectiveness in the local context; (iii) HR advocacy targeting law enforcement agencies and the Russian Church; and (iv) aligning best international HR practices with the objectives of local policy-makers, practitioners and service-users.

Abstract
The study of drug use by young people in the West has been transformed over the last decade by the development of sociological approaches to drug use which take serious account of the cultural context in which young people encounter drugs. One consequence is that the notion of 'peer pressure', as the primary articulation of the engagement between youth culture and drug use, has been displaced by that of 'normalisation', which envisages 'recreational' drug use as one expression of consumer-based youth cultural lifestyles. In stark contrast, academic discussion of drug use in Russia remains primarily concerned with the prevalence and health consequences of (intravenous) drug use while explanations of rising rates of drug use focus on structural factors related to the expansion of drugs supply and, to a lesser extent, post-Soviet social and economic dislocation. In this article, original empirical research in Russia is used to develop an understanding of young people's drug use that synthesises structural and cultural explanations of it. It does this by situating young people's narratives of their drugs choices in the context of local drugs markets and broader socio-economic processes. However, it attempts to go beyond seeing structural location as simply a 'constraint' on individual choice by adopting an understanding of 'youth culture' as a range of youth cultural practices and formations that simultaneously embody, reproduce and negotiate the structural locations of their subjects.

Abstract
OBJECTIVES We sought to determine the extent of HIV testing among urban injection drug users (IDUs) to assess whether an expansion of targeted testing programs would be consistent with national goals to identify previously undetected infections. METHODS IDUs in 5 US cities (Oakland, Calif; Chicago, Ill; Hartford and New Haven, Conn; and Springfield, Mass) were recruited either by chain referral or time-location sampling. The IDUs were questioned about HIV testing, and factors associated with HIV testing were analyzed. RESULTS Ninety-three percent of 1543 IDUs had been tested. Among those tested but who did not report having been told that they were HIV seropositive, 90% had been tested within the past 3 years. Women and syringe-exchange customers were more likely to have been tested ever and in the recent past. We estimated the number of undetected infections among urban IDUs in the United States to be less than 40000. CONCLUSIONS Testing for HIV has reached the vast majority of IDUs through the current options. Expending scarce prevention money to expand testing of IDUs is unlikely to be productive. Instead, resources should be used for proven HIV-prevention strategies including syringe exchange, drug treatment, and secondary prevention for those who are HIV positive.

Implementation of harm reduction in Central and Eastern Europe and Central Asia. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2006; 18:129-35.

Abstract
Harm reduction (HR) interventions began in Central-Eastern Europe and Central Asia in the mid-1980s with the establishment of substitution treatment (ST) in Yugoslavia. In the mid-1990s, the first needle and syringe programmes (NSPs) opened in selected countries following the outbreaks of HIV among injecting drug users (IDUs). The number of NSPs continues to increase via a combination of international and state funding with large expansions made possible via the Global Fund to Fight AIDS, Tuberculosis and Malaria. While ST is still unaccepted in several countries, others have made some progress which is especially visible in South Eastern and Central Europe and the Baltic States. Development of regional networking including Central and Eastern European HR Network and a number of national networks helped to coordinate joint advocacy effort and in some cases sustain HR services. Activism of drug users and people living with HIV (PLWH) increased in the region in the last several years and helped to better link HR with the affected communities. Still a number of challenges remain important for the movement today such as repressive drug policies; stigma and discrimination of IDUs, PLWH, sex workers and inmates, including poor access to prevention and treatment; lack of important components of HR work such as naloxone distribution and hepatitis B vaccination, prevention in prisons; issues of quality control; sustaining services after finishing of major international projects; reaching of adequate coverage and others.

Abstract
BACKGROUND Evidence highlights the prison as a high risk environment in relation to human immunodeficiency virus (HIV) and hepatitis C virus (HCV) transmission associated with injecting drug use. METHODS We undertook qualitative studies among 209 injecting drug users (IDUs) in three Russian cities: Moscow (n = 56), Volgograd (n = 83) and Barnaul in western Siberia (n = 70). RESULTS Over three-quarters (77%) reported experience of police arrest related to their drug use, and 35% (55% of men) a history of imprisonment or detention. Findings emphasize the critical role that penitentiary institutions may play as a structural factor in the diffusion of HIV associated with drug injection in the Russian Federation. While drugs were perceived to be generally available in penitentiary institutions, sterile injection equipment was scarce and as a consequence routinely shared, including within large groups. Attempts to clean borrowed needles or syringes were inadequate, and risk reduction was severely constrained by a combination of lack of injecting equipment availability and punishment for its possession. Perceptions of relative safety were also found to be associated with assumptions of HIV negativity, resulting from a perception that all prisoners are HIV tested upon entry with those found HIV positive segregated. CONCLUSION This study shows an urgent need for HIV prevention interventions in the Russian penitentiary system.

Abstract
OBJECTIVE To assess the effectiveness and cost-effectiveness of treating HIV-infected injection drug users (IDUs) and non-IDUs in Russia with highly active antiretroviral therapy HAART. DESIGN AND METHODS A dynamic HIV epidemic model was developed for a population of IDUs and non-IDUs. The location for the study was St. Petersburg, Russia. The adult population aged 15 to 49 years was subdivided on the basis of injection drug use and HIV status. HIV treatment targeted to IDUs and non-IDUs, and untargeted treatment interventions were considered. Health care costs and quality-adjusted life years (QALYs) experienced in the population were measured, and HIV prevalence, HIV infections averted, and incremental cost-effectiveness ratios of different HAART strategies were calculated. RESULTS With no incremental HAART programs, HIV prevalence reached 64% among IDUs and 1.7% among non-IDUs after 20 years. If treatment were targeted to IDUs, over 40 000 infections would be prevented (75% among non-IDUs), adding 650 000 QALYs at a cost of USD 1501 per QALY gained. If treatment were targeted to non-IDUs, fewer than 10 000 infections would be prevented, adding 400 000 QALYs at a cost of USD 2572 per QALY gained. Untargeted strategies prevented the most infections, adding 950 000 QALYs at a cost of USD 1827 per QALY gained. Our results were sensitive to HIV transmission parameters. CONCLUSIONS Expanded use of antiretroviral therapy in St. Petersburg, Russia would generate enormous population-wide health benefits and be economically efficient. Exclusively treating non-IDUs provided the least health benefit, and was the least economically efficient. Our findings highlight the urgency of initiating HAART for both IDUs and non-IDUs in Russia.

Abstract
OBJECTIVE To assess the HIV serostatus of injection drug users (IDU) in Ukraine, as well as associations between serostatus and selected demographic and risk factors. DESIGN AND METHODS IDU were recruited from the streets in Kiev, Odessa and Makeevka/Donesk. Participants were interviewed using an HIV risk behavior assessment and tested for HIV with a finger-stick rapid test. Multiple logistic regression was used to identify determinants of HIV infection. RESULTS Of the 891 IDUs surveyed, one-third came from each site and 22% were female. Their mean age was 29 years and on average they had been injecting for slightly more than 10 years. Seven hundred and seventy-eight of the total sample did not know their HIV status when first interviewed; they are the participants in this investigation. Overall, 33% tested positive for HIV, including 34% in Kiev, 51% in Odessa and 17% in Makeevka/Donesk. Independent predictors of HIV included injecting a sedative/opiate mixture, female sex, having sex with a person who was HIV positive or whose HIV status was unknown and injecting daily. HIV-negative IDU were significantly younger than those infected, they were more likely to be from Makeevka/Donesk and they were more likely to have been sexually active. CONCLUSIONS Rates of HIV infection among IDU vary considerably across Ukraine, although even in the site with the lowest rate nearly one in five was infected. The extent of drug and sex-related risk behaviors calls for interventions to reduce the spread of HIV and other infectious diseases.

Abstract
Injection drug users in Tirana, Albania and St. Petersburg, Russia were recruited into a study assessing HIV-related behaviors and HIV serostatus using Respondent Driven Sampling (RDS), a peer-driven recruitment sampling strategy that results in a probability sample. (Salganik M, Heckathorn DD. Sampling and estimation in hidden populations using respondent-driven sampling. Sociol Method. 2004;34:193-239). This paper presents a comparison of RDS implementation, findings on network and recruitment characteristics, and lessons learned. Initiated with 13 to 15 seeds, approximately 200 IDUs were recruited within 8 weeks. Information resulting from RDS indicates that social network patterns from the two studies differ greatly. Female IDUs in Tirana had smaller network sizes than male IDUs, unlike in St. Petersburg where female IDUs had larger network sizes than male IDUs. Recruitment patterns in each country also differed by demographic categories. Recruitment analyses indicate that IDUs form socially distinct groups by sex in Tirana, whereas there was a greater degree of gender mixing patterns in St. Petersburg. RDS proved to be an effective means of surveying these hard-to-reach populations.

Abstract
Respondent driven sampling (RDS) has been used in several counties to sample injecting drug users, sex workers (SWs) and men who have sex with men and as a means of collecting behavioural and biological health data. We report on the use of RDS in three separate studies conducted among SWs between 2004 and 2005 in the Russian Federation, Serbia, and Montenegro. Findings suggest that there are limitations associated with the use of RDS in SW populations in these regions. Findings highlight three main factors that merit further investigation as a means of assessing the feasibility and appropriateness of RDS in this high risk population: the network characteristics of SWs; the appropriate level of participant incentives; and lack of service contact. The highly controlled and hidden nature of SW organizations and weak SW social networks in the region can combine to undermine assumptions underpinning the feasibility of RDS approaches and potentially severely limit recruitment. We discuss the implications of these findings for recruitment and the use of monetary and non-monetary incentives in future RDS studies of SW populations in Eastern Europe.

Abstract
Evidence suggests rapid diffusion of injecting drug use and associated outbreaks of HIV among injecting drug users (IDUs) in the Russian Federation and Eastern Europe. There remains a need for research among non-treatment and community-recruited samples of IDUs to better estimate the dynamics of HIV transmission and to improve treatment and health services access. We compare two sampling methodologies "respondent-driven sampling" (RDS) and chain referral sampling using "indigenous field workers" (IFS) to investigate the relative effectiveness of RDS to reach more marginal and hard-to-reach groups and perhaps to include those with the riskiest behaviour around HIV transmission. We evaluate the relative efficiency of RDS to recruit a lower cost sample in comparison to IFS. We also provide a theoretical comparison of the two approaches. We draw upon nine community-recruited surveys of IDUs undertaken in the Russian Federation and Estonia between 2001 and 2005 that used either IFS or RDS. Sampling effects on the demographic composition and injecting risk behaviours of the samples generated are compared using multivariate analysis. Our findings suggest that RDS does not appear to recruit more marginalised sections of the IDU community nor those engaging in riskier injecting behaviours in comparison with IFS. RDS appears to have practical advantages over IFS in the implementation of fieldwork in terms of greater recruitment efficiency and safety of field workers, but at a greater cost. Further research is needed to assess how the practicalities of implementing RDS in the field compromises the requirements mandated by the theoretical guidelines of RDS for adjusting the sample estimates to obtain estimates of the wider IDU population.

Abstract
OBJECTIVES We examined risk factors for syphilis infection among injection drug users in 3 Russian Federation cities, focusing particular attention on the potential roles of gender and sex work. METHODS We conducted a cross-sectional survey of injection drug users in Moscow, Volgograd, and Barnaul, collecting behavioral data and testing for antibodies to Treponema pallidum. Associations between presence of antibodies to T pallidum and covariates were explored. RESULTS Overall, the prevalence of antibodies to T pallidum was 11% (95% confidence interval=9.7%, 13.1%). Syphilis was associated with involvement in sex work and with gender in Moscow and Barnaul but not in Volgograd. Female injection drug users not involved in sex work were more likely than men to be younger and to have recently begun to inject; female injection drug users involved in sex work were more likely than those not involved in sex work to inject daily. CONCLUSIONS Syphilis transmission dynamics varied by region. Sex work can increase syphilis risk among injection drug users, potentially feeding the momentum of sexually transmitted HIV and syphilis among noninjectors. Targeted interventions are needed to reduce both sexual and injection risk behaviors among injection drug users.
