Injection-related Risk Behaviors Research Articles

A cross-sectional assessment of injection of "salts" and HIV transmission-related behaviours among a cohort of people who inject drugs in Kyrgyzstan.

Despite the increasing availability of new psychoactive substances (hereafter referred to as "salts") in Eastern Europe and Central Asia, there is a dearth of epidemiological data on the relationship between injecting "salts" and HIV risk behaviours. This is particularly relevant in settings where injection drug use accounts for a substantial proportion of the HIV burden, such as in Kyrgyzstan, a former Soviet Republic. This study assessed whether injecting "salts" is associated with sexual and injection-related HIV risk behaviours among people who inject drugs in Kyrgyzstan. The Kyrgyzstan InterSectional Stigma Study is a cohort of people who inject drugs in Kyrgyzstan's capital of Bishkek and the surrounding rural administrative division of Chuy Oblast. We conducted a cross-sectional analysis using survey data collected from cohort participants between July and November 2021, which included information on injection drug use (including "salts") and HIV risk behaviours. To minimize confounding by measured covariates, we used inverse-probability-weighted logistic and Poisson regression models to estimate associations between recent "salt" injection and HIV risk behaviours. Of 181 participants included in the analysis (80.7% men, 19.3% women), the mean age was 40.1 years (standard deviation [SD] = 8.8), and 22% (n = 39) reported that they had injected "salts" in the past 6 months. Among people who injected "salts," 72% (n = 28) were men, and most were ethnically Russian 59% (n = 23), with a mean age of 34.6 (SD = 9.6). Injecting "salts" was significantly associated with a greater number of injections per day (adjusted relative risk [aRR] = 1.59, 95% confidence interval [CI] = 1.30-1.95) but lower odds of using syringe service programmes in the past 6 months (adjusted odds ratio [aOR] = 0.20, 95% CI = 0.12-0.32). Injecting "salts" was also significantly associated with lower odds of condomless sex in the past 6 months (aOR = 0.42, 95% CI = 0.24-0.76) and greater odds of having ever heard of pre-exposure prophylaxis (aOR = 4.80, 95% CI = 2.61-8.83). (PWID) people who inject drugs who inject "salts" are a potentially emergent group with increased HIV acquisition risk in Kyrgyzstan. Targeted outreach bundled with comprehensive harm reduction and pre-exposure prophylaxis services are needed to prevent transmission of HIV and other blood-borne viruses.

Injection Behaviors and Use of Syringe Service Programs over Time among People Who Inject Drugs in Baltimore, Maryland

Introduction: People who inject drugs (PWID) are at increased risk for infectious disease transmission, including hepatitis C and HIV. Understanding trends in injection risk behaviors and syringe service program (SSP) use over time can help improve infectious disease prevention and other harm reduction services. Methods: Using National HIV Behavioral Surveillance System data from Baltimore, Maryland, we examined changes in receptive sharing of (1) syringes, (2) injection equipment, (3) syringes to divide drugs; and (4) receipt of syringes from SSPs among PWID from 2009 to 2018 (n = 518 in 2009, n = 638 in 2012, n = 586 in 2015, and n = 575 in 2018) using unadjusted and adjusted logistic models calculated across time for the total sample. Results: The conditional probability of receptive sharing of syringes and receipt of syringes from SSPs remained relatively stable, while receptive sharing of injection equipment and receptive sharing of syringes to divide drugs dropped substantially after 2009. White race and daily injection frequency were positively associated with sharing syringes and injection equipment and negatively associated with SSP use over time. In 2015, there was a notable shift such that women were twice as likely as men to receive syringes from SSPs and less likely than men to report the use of shared syringes or equipment. Conclusion: Findings indicate overall steady or decreasing trends in injection risk and steady trends in SSP usage over time, with some notable improvements among women and indications of shifting drug market patterns. Injection-related risk behaviors remain high among White PWID and may require targeted outreach and interventions.

Evaluating the Mediating Role of Recall of Intervention Knowledge in the Relationship Between a Peer-Driven Intervention and HIV Risk Behaviors Among People Who Inject Drugs.

Peer-driven interventions can be effective in reducing HIV injection risk behaviors among people who inject drugs (PWID). We employed a causal mediation framework to examine the mediating role of recall of intervention knowledge in the relationship between a peer-driven intervention and subsequent self-reported HIV injection-related risk behavior among PWID in the HIV Prevention Trials Network (HPTN) 037 study. For each intervention network, the index participant received training at baseline to become a peer educator, while non-index participants and all participants in the control networks received only HIV testing and counseling; recall of intervention knowledge was measured at the 6-month visit for each participant, and each participant was followed to ascertain HIV injection-related risk behaviors at the 12-month visit. We used inverse probability weighting to fit marginal structural models to estimate the total effect (TE) and controlled direct effect (CDE) of the intervention on the outcome.The proportion eliminated (PE) by intervening to remove mediation by the recall of intervention knowledge was computed. There were 385 participants (47% in intervention networks) included in the analysis. The TE and CDE risk ratios for the intervention were 0.47 [95% confidence interval (CI): 0.28, 0.78] and 0.73 (95% CI: 0.26, 2.06) and the PE was 49%. Compared to participants in the control networks, the peer-driven intervention reduced the risk of HIV injection-related risk behavior by 53%. The mediating role of recall of intervention knowledge accounted for less than 50% of the total effect of the intervention, suggesting that other potential causal pathways between the intervention and the outcome, such as motivation and skill, self-efficacy, social norms and behavior modeling, should be considered in future studies.

Relapse Rate after Opioid Detoxification in Drug Addict Patients

Background: Drug addiction is widely regarded as a pathological condition that involves the continued abuse of drugs in the development of drug-seeking behavior and a decrease in the ability to respond to naturally rewarding stimuli.
 Objective: To determine the frequency of relapse after opioid detoxification in drug addict patients.
 Methods: A descriptive cross-sectional survey was performed in psychiatry department of Pakistan Institute of Medical Sciences, PIMS, Islamabad, from October 2017 to April 2018. All adult patients who were using cannabis for at least 1 year, irrespective of gender ages between 18 to 60 years were included in the study. For drug use characteristics about preferred choice of drugs and injection-related risk behaviors were noted and analyzed. All findings were entered in a structured Proforma. Data was entered in SPSS version 21 and analyzed. Effects modifiers like age, gender, marital status, types of drugs, etc., were controlled by stratification. Post stratification chi square test was applied. A p value ≤ 0.05 was considered significant.
 Results: Total 310 patients were included; 83% patients were male and 17% were females. The mean age of the patients was 39.02±21.42 years. 70% patients had relapse after opioid detoxification while 30% patients had NO relapse. The relapse rate after detoxification was more common in first month of detoxification (56%). After 3 months the relapse rate after detoxification was 12.5%. The statistical analysis showed that there was a very significant association between types of drugs, ages of patients, marital status and relapse rate (p ≤ 0.05). There was an insignificant association between gender and relapse rate (p ≥ 0.5).
 Conclusion: The study concluded that the relapse within six months of opioid detoxification in drug addicts is very common. Many factors contribute in relapse rate.

HIV Risk Among Urban and Suburban People Who Inject Drugs: Elevated Risk Among Fentanyl and Cocaine Injectors in Maryland.

Drug overdose remains a leading cause of death in the US, with growing rates attributable to illicit fentanyl use. Recent HIV outbreaks among people who inject drugs (PWID) and service disruptions from COVID-19 have renewed concerns on HIV resurgence. We examined the relationship between fentanyl use and three injection-related HIV risk behaviors among PWID in Baltimore City (BC) and Anne Arundel Country (AAC), Maryland. PWID (N = 283) were recruited to the study through targeted sampling at street-based locations in BC and AAC from July 2018 to March 2020. Receptive syringe sharing (RSS) [adjusted odds ratio (AOR): 2.8, 95% confidence interval (CI): 1.2–6.3] and daily injecting (AOR: 1.9, 95% CI: 1.0–3.6) were associated with injecting fentanyl and cocaine together. Fentanyl availability and COVID-19 bring new HIV prevention challenges, particularly among those who inject fentanyl with cocaine, highlighting the importance to expand and sustain harm reduction, prevention, and treatment services for PWID to reduce HIV and overdose burden.

Reduction in injection risk behaviors after implementation of a syringe services program, Miami, Florida

IntroductionSyringe services programs (SSPs) are evidence-based HIV prevention programs for people who inject drugs. However, not all SSPs operate evidence-based syringe distribution models, such as needs-based distribution. This study aims to provide preliminary evidence from the IDEA SSP on changes in injection risk behaviors over time, and to examine factors, including syringe coverage, associated with injection risk behavior trajectories over time under a one-for-one syringe distribution model. MethodsWe used a prospective observational study design to generate a cohort of SSP clients who completed three behavioral assessments at SSP service visits between December 2016 and January 2020 (N = 115). The study used generalized estimating equations (GEE) to examine the relationship between covariate measures and the primary outcomes. The primary outcomes were 1) sharing of any injection equipment (e.g. syringes, needles, cookers, cottons) in the previous 30 days (yes/no) and 2) reusing of needles/syringes in the previous 30 days (yes/no). ResultsMen were more likely to report reusing syringes (aRR = 1.15, 95% CI: 1.01–1.37) and those who reported injecting in public were less likely to report reusing syringes (aRR = 0.90, 95% CI: 0.82–0.99). HCV-positive clients had a 62% reduction in sharing injection equipment and those who reported public injection had a 62% increase in sharing injection equipment over time. Most importantly, increasing syringe coverage was associated with a decrease in both sharing injection equipment (aRR = 0.42, 95% CI: 0.25–0.72) and reusing syringes (aRR = 0.79, 95% CI: 0.66–0.95). ConclusionThis study provides preliminary evidence of reductions in injection-related risk behaviors from the IDEA SSP and highlights potential high priority groups, such as people experiencing homelessness, that may need additional intervention. In addition, improving syringe coverage among SSP clients may be an important factor in reducing behaviors that place individuals at risk for contracting HIV and HCV.

Baseline prevalence and correlates of HIV and HCV infection among people who inject drugs accessing a syringe services program; Miami, FL

BackgroundBlood-borne viral infections, such as HIV and hepatitis C (HCV), are common infections among people who inject drugs (PWID). This study aims to determine the prevalence of HIV and HCV infection among PWID accessing the first legal syringe services program (SSP) in the state of Florida, along with examining baseline correlates of HIV and HCV infection.MethodsBaseline behavioral enrollment assessments of 837 participants accessing an SSP for the first time were analyzed. Patients self-reporting or testing HIV or HCV positive at the enrollment visit were included. Socio-demographic, drug use, and injection-related risk behaviors in the last 30 days were compared across groups defined by all combinations of HIV and HCV serostatus.Bivariate and multivariable logistic regression models were used to assess correlates of baseline HCV and HIV infection independently.ResultsOverall prevalence for HCV and HIV infection were 44.4% and 10.2%, respectively. After adjusting for confounders, the most significant correlates of baseline HCV infection were age (aOR = 1.01), lower education level (aOR = 1.13), currently homeless (aOR = 1.16), injecting more than seven times a day (aOR = 1.14), reusing syringes (aOR = 1.18), and sharing injection equipment (aOR = 1.13). The most significant predictors of baseline HIV infection were age (aOR = 1.01), non-Hispanic Black race (aOR = 1.28), Hispanic ethnicity (aOR = 1.12), gay or bisexual orientation (aOR = 1.22), and methamphetamine injection (aOR = 1.22). In addition, heroin injection (aOR = 0.92) was significantly associated with a lower odds of HIV infection.Discussion/conclusionBaseline behavioral predictors differed between HIV infection and HCV infection among participants accessing syringe services. Understanding the risk factors associated with each infection should be considered when developing additional harm reduction interventions tailored for diverse PWID populations served at SSPs.

Policing Practices and HIV Risk Among People Who Inject Drugs - A Systematic Literature Review

Background: Laws and their enforcement act as structural determinants of health. Among people who inject drugs (PWID) in numerous global settings, police encounters (e.g. syringe confiscation, physical assault) have been associated with health harms. However, these relationships have not yet been systematically assessed. We conducted a systematic literature review to quantify the contribution of policing to HIV risk among PWID. Methods: We screened MEDLINE, sociological databases and grey literature for studies conducted from 1981-November 2018 that included estimates of HIV infection/risk behaviors and policing practices adversely related to PWID health. Abstracts containing valid associations were selected for further review. We extracted and summarized quantitative findings from eligible studies. Findings: We screened 8,201 abstracts, reviewed 175 full-text articles and included 27 eligible analyses from nine countries (Russia, Mexico, USA, Canada, Ukraine, Thailand, Malaysia, China and India). Heterogeneity in variable and endpoint selection precluded meta-analyses. In 6 (22%)% studies, HIV infection among PWID was significantly associated with policing, including syringe confiscation, reluctance to buy or carry syringes for fear of police, rushed injection due to police presence, fear of arrest, being arrested for planted drugs, and physical abuse. Examining injection-related HIV risk behaviors as analytical endpoints, 16 (59)% studies identified policing practices to be independently associated with syringe sharing, shooting gallery utilization, and seeking informal injection assistance. In 9 (33%), policing was associated with PWID avoidance of harm reduction services, including syringe exchange, methadone maintenance, and safe consumption facilities. Most studies focused on high-income settings. Interpretation: Globally, evidence suggests that policing substantially shapes the HIV risk environment for PWID, but lower-income settings are underrepresented in research. Curbing injection-related HIV risk may necessitate additional structural interventions. Methodological harmonization could facilitate knowledge generation on the role of police as a determinant of population health.

Identification of a Syndemic of Blood-Borne Disease Transmission and Injection Drug Use Initiation at the US-Mexico Border.

Efforts to prevent injection drug use (IDU) are increasingly focused on the role that people who inject drugs (PWID) play in the assistance with injection initiation. We studied the association between recent (ie, past 6 months) injection-related HIV risk behaviors and injection initiation assistance into IDU among PWID in the US-Mexico border region. Preventing Injecting by Modifying Existing Responses (PRIMER) is a multicohort study assessing social and structural factors related to injection initiation assistance. This analysis included data collected since 2014 from 2 participating cohorts in San Diego and Tijuana. Participants were 18 years and older and reported IDU within the month before study enrollment. Logistic regression analyses were conducted to assess the association between recent injection-related HIV risk behaviors (eg, distributive/receptive syringe sharing, dividing drugs in a syringe, and paraphernalia sharing) and recent injection initiation assistance. Among 892 participants, 41 (4.6%) reported recently providing injection initiation assistance. In multivariable analysis adjusting for potential confounders, reporting a higher number of injection-related risk behaviors was associated with an increased odds of recently assisting others with injection initiation (adjusted odds ratio per risk behavior: 1.3; 95% confidence interval: 1.0 to 1.6, P = 0.04). PWID who recently engaged in one or more injection-related HIV risk behavior were more likely to assist others in injection initiation. These results stress the syndemic of injection initiation and risk behaviors, which indicates that prevention of injection-related HIV risk behaviors might also reduce the incidence of injection initiation.

Risk behaviours and viral infections among drug injecting migrants from the former Soviet Union in Germany: Results from the DRUCK-study

BackgroundHigh prevalence of drug use and injection-related risk behaviours have been reported among former Soviet Union (FSU)-migrants. To investigate hepatitis C (HCV) and HIV seroprevalence and related risk behaviours in this subgroup in Germany, we compared first generation FSU-migrants and native Germans using data from a sero-behavioural survey of people who inject drugs (PWID). MethodsCurrent injectors were recruited using respondent-driven sampling in eight German cities in 2011–2014. Questionnaire-based interviews were conducted and dried blood spots collected and tested for anti-HCV, HCV-RNA, and anti-HIV1/2. Descriptive and multivariable analyses (MVA) were performed. ResultsA total of 208 FSU-born and 1318 native German PWID were included in the analysis. FSU-migrants were younger than Germans (median age: 33 vs. 39 years), and more often male (83.1% vs. 75.9%, p = 0.022). HCV seroprevalence was 74.5% in FSU-migrants vs. 64.6% in Germans (p = 0.006), HIV seroprevalence was 5.8% and 4.6%, respectively (p = 0.443). The proportion of FSU-migrants reporting injecting-related risk behaviours was higher than among Germans: injecting daily (39.4% vs. 30.2%, p = 0.015), with friends (39.2% vs. 31.2%, p = 0.038), cocaine (32.7% vs. 23.8%, p = 0.044), more than one drug (18.2% vs. 9.6%, p = 0.006), and sharing filters/cookers (35.5% vs. 28.0%, p = 0.045). No statistically significant differences were observed in HIV/HCV testing rates (range: 50.7%–65.6%), opioid substitution treatment (43.9% vs. 50.5%), and access to clean needles/syringes (89.8% vs. 90.3%). In MVA, risk for HCV-infection was increased in male FSU-migrants compared to German males (OR 3.32, p = 0.006), no difference was identified between female FSU-migrants and German females (OR: 0.83, p = 0.633). ConclusionMale FSU-migrants were at highest risk of being HCV infected. Therefore, targeted actions are needed to ensure access and acceptance of harm reduction measures, including HCV-testing and -treatment for this subpopulation of PWID.

Resilience, Distress, and Dependence Influence Injection Related Risk among People Who Inject Drugs

Substance use behavior, particularly injecting illicit substances, can lead to a variety of negative health outcomes. Psychological distress and substance dependence can contribute to injection-related risk behaviors, behaviors that can lead to transmission of bloodborne pathogens. This study examines how resilience (measured by the Conner Davidson Resilience Scale) might contribute to reducing risk, specifically in relation to psychological distress (measured by the Kessler 6 scale) and substance dependence (measured by the severity of dependence scale). The aim of this study was to examine the intersection between resilience, psychological distress, and severity of dependence, and how these psychosocial mechanisms might influence injection-related risk behaviors including sharing syringes and other injection equipment. A total of 622 people who inject drugs who live in New Orleans were recruited using respondent-driven sampling as part of the National HIV Behavioral Surveillance. In multiple binary logistic regression analyses, psychological distress was a significant predictor of syringe sharing behavior after controlling for resilience and dependence. Resilience and dependence are independent significant predictors of syringe sharing behavior, which warrants further investigation of how resilience, psychological distress, dependence, and injection-related risk are interrelated. These findings provide a foundation for further research that may inform prevention programs focused on reducing negative health outcomes associated with high-risk injection behaviors.

Reduction of Injection-Related Risk Behaviors After Emergency Implementation of a Syringe Services Program During an HIV Outbreak.

To describe injection-related HIV risk behaviors preimplementation and postimplementation of an emergency syringe services program (SSP) in Scott County, Indiana, after an HIV outbreak among persons who inject drugs (PWID). Mixed methods retrospective pre-post intervention analysis. We analyzed routine SSP program data collected at first and most recent visit among clients with ≥2 visits, ≥7 days apart from April 4 to August 30, 2015, to quantify changes in injection-related risk behaviors. We also analyzed qualitative data collected from 56 PWID recruited in Scott County to understand factors contributing to these behaviors. SSP clients included in our analysis (n = 148, 62% of all SSP clients) reported significant (P < 0.001) reductions over a median 10 weeks (range 1-23) in syringe sharing to inject (18%-2%) and divide drugs (19%-4%), sharing other injection equipment (eg, cookers) (24%-5%), and number of uses of the same syringe [2 (interquartile range: 1-4) to 1 (interquartile range: 1-1)]. Qualitative study participants described access to sterile syringes and safer injection education through the SSP, as explanatory factors for these reductions. Injection frequency findings were mixed, but overall suggested no change. The number of syringes returned by SSP clients increased from 0 at first visit to median 57. All qualitative study participants reported using sharps containers provided by the SSP. Analyses of an SSP program and in-depth qualitative interview data showed rapid reduction of injection-related HIV risk behaviors among PWID post-SSP implementation. Sterile syringe access as part of comprehensive HIV prevention is an important tool to control and prevent HIV outbreaks.

Do needle and syringe programs reduce risky behaviours among people who inject drugs in Kermanshah City, Iran? A coarsened exact matching approach.

In this study, we used a 'coarsened exact matching' method to evaluate the relationship between two levels of needle and syringe program (NSP) utilisation and HIV-related risk behaviours among people who inject drugs (PWID). Using snowball sampling, we recruited 500 PWID (all male) in Kermanshah City, Iran between September and December 2014 in a cross-sectional survey. We categorised participants into two groups, including high (i.e. receiving 60% or more of their syringes from an NSP) and low (i.e. receiving less than 60% of their syringes from NSP) NSP users. Then, we applied coarsened exact matching to match the two groups based on confounding covariates (age, place of residence, income, receiving methadone maintenance treatment) and made statistically equivalent comparison groups to estimate the effect of the NSP on injection risk behaviours. Participants with low NSP use were more likely to report borrowing syringes in past 2 months (odds ratio [OR] 1.71; 95% confidence interval [CI] 1.30, 1.86; P < 0.04), in comparison with participants with high NSP use. Regarding recent syringe lending, low NSP use was also significantly and positively associated with this outcome (OR 3.34; 95% CI 1.70, 5.20; P < 0.02). Reusing one's own syringe was reported more frequently in low NSP use group (OR 1.40; 95% CI 1.22, 3.97; P < 0.03). NSPs are a promising approach to reduce injection-related risk behaviours among PWID in Kermanshah, Iran. Expanded coverage of high-quality NSPs is recommended.

Injection-Related Risk Behavior and Engagement in Outreach, Intervention and Prevention Services Across 20 US Cities.

Monitoring the effects of HIV prevention efforts on risk behaviors among persons who inject drugs is a key to inform prevention programs and policy. Using data from the 2012 National HIV Behavioral Surveillance interviews with persons who inject drugs across 20 US cities (n = 10,171), we conducted latent class analysis to identify injection risk classes and assess the relationship between engagement in prevention services and injection-related risk behavior. We conducted stratified analyses to examine the consistency of these associations across different geographical regions. The latent class analysis identified 6 distinct classes of injection-related risk behavior. The class structure was consistent across regions of the United States, but the distribution of risk classes varied significantly across regions. With covariate adjustment, the South had the most high-risk behavior (21%) and the Midwest had the least (6%). Participation in syringe access services and other prevention services was the lowest in the South. Syringe access was associated with a significantly lower likelihood of membership in the highest risk class in all regions except the Midwest. Participation in individual or group intervention with a practical skills component was associated with less risky injection behavior in all regions except the Northeast. Interventions that featured only safer injection information and discussion had no relationship with risk class. Our findings support evidence of the effectiveness of syringe service programs and safer injection skills training in reducing high-risk injection behavior and underscore the need to improve access to these prevention interventions in the South of the United States.

Associations of place characteristics with HIV and HCV risk behaviors among racial/ethnic groups of people who inject drugs in the United States

PurposeInvestigate whether characteristics of geographic areas are associated with condomless sex and injection-related risk behavior among racial/ethnic groups of people who inject drugs (PWID) in the United States. MethodsPWID were recruited from 19 metropolitan statistical areas for 2009 National HIV Behavioral Surveillance. Administrative data described ZIP codes, counties, and metropolitan statistical areas where PWID lived. Multilevel models, stratified by racial/ethnic groups, were used to assess relationships of place-based characteristics to condomless sex and injection-related risk behavior (sharing injection equipment). ResultsAmong black PWID, living in the South (vs. Northeast) was associated with injection-related risk behavior (adjusted odds ratio [AOR] = 2.24, 95% confidence interval [CI] = 1.21–4.17; P = .011), and living in counties with higher percentages of unaffordable rental housing was associated with condomless sex (AOR = 1.02, 95% CI = 1.00–1.04; P = .046). Among white PWID, living in ZIP codes with greater access to drug treatment was negatively associated with condomless sex (AOR = 0.93, 95% CI = 0.88–1.00; P = .038). ConclusionsPolicies that increase access to affordable housing and drug treatment may make environments more conducive to safe sexual behaviors among black and white PWID. Future research designed to longitudinally explore the association between residence in the south and injection-related risk behavior might identify specific place-based features that sustain patterns of injection-related risk behavior.

Reduction in Injection Risk Behaviors After Institution of an Emergency Syringe Exchange Program During an HIV Outbreak Among Persons Who Inject Drugs, Indiana 2015

Background. On April 6, 2015, an emergency syringe exchange program (SEP) was implemented in response to an unprecedented HIV outbreak linked to injection drug use in a small rural Indiana community. To assess impact of the SEP, we compared injection-related risk behaviors reported over time. Methods. At each SEP visit, clients received sterile syringes, a wound kit, harm reduction education, and referrals to health and substance abuse services. Returned syringes were safely disposed and clients were surveyed about current risk behaviors. We analyzed data on clients with >2 SEP visits ≥7 days apart through June 6, 2015. Differences in medians and percentages between clients' first and most recent visit were assessed using the Kruskal-Wallis test, or χ2 or Fisher exact test. Results. We evaluated data from 100 qualifying SEP clients who contributed a total of 361 visits (median: 3) and received 19,376 syringes: 55% were male, median age was 33 years (interquartile range [IQR]: 26–40). The median interval between first and most recent visit was 27 days (IQR: 16–40). Sharing syringes to inject declined significantly by 85% between the first and most recent visits (table). The frequency of reusing the same syringe also declined significantly. The number of syringes returned and distributed both increased significantly. Decreases in sharing syringes to divide drugs and sharing other injection equipment were not statistically significant. Conclusion. Among clients enrolled during the first two months of an emergency SEP, many injection-related risk behaviors declined significantly. Emergency SEPs can rapidly reduce risk behaviors capable of transmitting HIV in an outbreak setting.

Patterns of substance use and correlates of lifetime and active injection drug use among women in Malaysia

ABSTRACTBackground: While drug use is associated with HIV risk in Southeast Asia, little is known about substance use behaviors among women, including drug injection. Objectives: To describe patterns of substance use among women using alcohol and drugs in Malaysia and identify correlates of lifetime and active drug injection, a risk factor for HIV transmission. Methods: A survey of 103 women who used drugs in the last 12 months assessed drug use history and frequency, including drug injection and drug use during pregnancy, self-reported HIV-status, childhood and adulthood physical and sexual abuse, and access to and utilization of harm reduction services, including needle-syringe exchange programs (NSEP) and opioid agonist maintenance therapy (OAT). Principal component analyses (PCA) were conducted to assess drug use grouping. Results: Amphetamine-type substances (ATS; 82.5%), alcohol (75.7%) and heroin (71.8%) were the most commonly used drugs across the lifetime. Drug injection was reported by 32.0% (n = 33) of participants with 21.4% (n = 22) having injected in the last 30 days. PCA identified two groups of drug users: opioids/benzodiazepines and club drugs. Lifetime drug injection was significantly associated with lower education, homelessness, prior criminal justice involvement, opioid use, polysubstance use, childhood physical and sexual abuse, and being HIV-infected, but not with prior OAT. Conclusion: Women who use drugs in Malaysia report high levels of polysubstance use and injection-related risk behaviors, including sharing of injection equipment and being injected by others. Low OAT utilization suggests the need for improved access to OAT services and other harm reduction measures that prioritize women.

Opioid Use Trajectories, Injection Drug Use, and Hepatitis C Virus Risk Among Young Adult Immigrants from the Former Soviet Union Living in New York City

Available evidence suggests that young former Soviet Union immigrants in New York City have high rates of non-medical prescription opioid and heroin use, drug injection and injection-related risk behavior, making them vulnerable to hepatitis C virus (HCV)/human immunodeficiency virus (HIV) infection, overdose and associated harms. This group has been the focus of little research, however. This paper presents quantitative and qualitative data from 80 former Soviet immigrants (ages 18-29) to characterize their opioid use trajectories, injection risk behavior, HCV/HIV testing histories and self-reported HCV/HIV serostatus, and provides clinically meaningful data to inform tailored education, prevention and harm reduction interventions.

Expanding substance use treatment options for HIV prevention with buprenorphine-naloxone: HIV Prevention Trials Network 058.

Injection opioid use plays a significant role in the transmission of HIV infection in many communities and several regions of the world. Access to evidence-based treatments for opioid use disorders is extremely limited. HIV Prevention Trials Network 058 (HPTN 058) was a randomized controlled trial designed to compare the impact of 2 medication-assisted treatment (MAT) strategies on HIV incidence or death among opioid-dependent people who inject drugs (PWID). HIV-negative opioid-dependent PWID were recruited from 4 communities in Thailand and China with historically high prevalence of HIV among PWID. A total of 1251 participants were randomly assigned to either (1) a 1-year intervention consisting of 2 opportunities for a 15-day detoxification with buprenorphine/naloxone (BUP/NX) combined with up to 21 sessions of behavioral drug and risk counseling [short-term medication-assisted treatment (ST-MAT)] or (2) thrice-weekly dosing for 48 weeks with BUP/NX and up to 21 counseling sessions [long-term medication-assisted treatment (LT-MAT)] followed by dose tapering. All participants were followed for 52 weeks after treatment completion to assess durability of impact. Although the study was stopped early due to lower than expected occurrence of the primary end points, sufficient data were available to assess the impact of the interventions on drug use and injection-related risk behavior. At week 26, 22% of ST-MAT participants had negative urinalyses for opioids compared with 57% in the LT-MAT (P < 0.001). Differences disappeared in the year after treatment: at week 78, 35% in ST-MAT and 32% in the LT-MAT had negative urinalyses. Injection-related risk behaviors were significantly reduced in both groups after randomization. Participants receiving BUP/NX 3 times weekly were more likely to reduce opioid injection while on active treatment. Both treatment strategies were considered safe and associated with reductions in injection-related risk behavior. These data support the use of thrice-weekly BUP/NX as a way to reduce exposure to HIV risk. Continued access to BUP/NX may be required to sustain reductions in opioid use.

Access to harm reduction programs among persons who inject drugs: Findings from a respondent-driven sampling survey in Tehran, Iran

BackgroundOver the past two decades, drug injection-related risk behaviors have been the major drivers of the HIV epidemic in Iran. This study assesses the access of people who injected drugs (PWID) to harm reduction services (needle-exchange programs [NEP] and methadone maintenance treatment [MMT]) in Tehran, Iran in 2007, almost five years after the large-scale implementation of these programs. Methods572 consenting PWID (>18 years old, ever injected in the past month, lived in Tehran or its suburbs) were recruited (24 seeds) into a sero-behavioral survey using respondent-driven sampling method. Participants completed a face-to-face interview about HIV-related risk behaviors and access to harm reduction services. We calculated adjusted population estimates using RDSAT. ResultsOverall, 99.2% of the participants were male, 41.6% aged between 30 and 39 years old, 55.4% lived alone in the past year, 83.2% were ever incarcerated, and 88.8% lived in the southern areas of Tehran. In terms of “awareness” and “use” of services among PWID, 62.8% and 54.8% reported for NEP (respectively) and 19.7% and 9.1% for drug treatment services (respectively). PWID who lived in Northwest and South-central Tehran were more likely to be aware (85.0% and 82.8%, respectively) of one or more services than PWID who lived elsewhere. Similarly, PWID who lived with friends were more likely to be aware of (88.6%) and use (85.9%) services (vs. other living partners). Overall, 11% of the participants were aware of but had not used any harm reduction services. ConclusionsDespite a relatively high level of access to NEP among PWID in Tehran, a sizable fraction of the population remains without access to other services five years after their implementation. The use of harm reduction may be affected by certain PWID characteristics (e.g., living partners and geographical location). Ongoing surveillance activities are necessary to track change in access over time.
