Abstract
IMPORTANCE Hepatitis C virus (HCV) reinfection after curative treatment remains a concern for people who inject drugs. OBJECTIVE To assess the incidence of HCV reinfection and associated risk factors. DESIGN, SETTING, AND PARTICIPANTS This cohort study is a secondary analysis of a randomized clinical trial that was conducted across opioid treatment programs and community health centers in the US between September 2016 and August 2018. The current analyses were performed in March 2022. People who inject drugs who achieved sustained virologic response (SVR) were followed for up to 42 months. Exposure Patients were randomly assigned to receive modified directly observed therapy or patient navigation. MAIN OUTCOMES AND MEASURES The primary outcome was rate of HCV reinfection. Change in reinfection rates over time was assessed using a Poisson regression model. RESULTS A total of 415 participants (mean [SD] age, 44.7 [11.5] years; 302 male [72.8%]) achieved a SVR and had 1 or more post-SVR assessments for HCV RNA. Overall, 302 (72.8%) reported recent injection drug use, 192 (46.3%) were living in unstable housing, and 313 (75.4%) had received recent methadone or buprenorphine for opioid use disorder. The overall reinfection rate was 11.4 per 100 person-years at risk (95% CI, 8.7-14.7 per 100 person-years at risk) over 518 person-years of follow-up. Reinfection rates varied significantly across sites, ranging from 2.9 per 100 person-years at risk (95% CI, 0.1-16.3 per 100 person-years) to 25.2 per 100 person-years at risk (95% CI, 15.6-38.5 per 100 person-years at risk) (P = .006). There was a significant decrease in incident reinfection with increasing post-SVR follow-up (weeks 0-24, 15.5 per 100 person-years; 95% CI, 10.3-22.3 per 100 person-years; weeks 73-144, 4.3 per 100 person-years; 95% CI, 0.9-12.5 per 100 person-years; P = .008). Reinfection rates were lower for participants aged 40 years or older than for younger participants (adjusted incidence rate ratio, 0.32; 95% CI, 0.18-0.57) and for participants for whom methamphetamine was not detected in urinary drug screening compared with participants for whom methamphetamine was detected (adjusted incidence rate ratio, 0.41; 95% CI, 0.21-0.82). Participants who reported injection drug use within the preceding 3 months had higher risk of reinfection than those who did not have recent injection drug use (adjusted incidence rate ratio, 3.33; 95% CI, 1.86-5.97). CONCLUSIONS AND RELEVANCE In this cohort study of people who injected drugs and were treated for HCV infection in community settings, reinfection was high in the period immediately after SVR but decreased significantly over time. These findings highlight the importance of early intervention to prevent reinfection. Trial Registration ClinicalTrials.gov Identifier: NCT02824640.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 128:104422. [PMID: 38703621 PMCID: PMC11213664 DOI: 10.1016/j.drugpo.2024.104422] [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: 08/30/2023] [Revised: 03/20/2024] [Accepted: 04/04/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND Personal syringe reuse (i.e., reuse of one's own syringes) can place people who inject drugs at increased risk for infectious disease but has received relatively little attention in published literature. The purpose of this study is to identify factors associated with syringe reuse among people who inject drugs in rural Kentucky. METHODS Participants (n = 238) completed interviewer-administered questionnaires on syringe reuse and demographic, behavioral, and service access characteristics. Unadjusted negative binomial regression with cluster-robust standard errors was used to model the associations with a logged offset for number of injections in the past 30 days. RESULTS The average age of the sample was 35 and 59.7 % were male. Most participants (77.7 %) reused syringes at least once in the past 30 days, using each syringe a median of three times. Reuse was higher among those who were older and reported a higher street price for syringes. Syringe reuse was lower among people who were within walking distance to a syringe service program (SSP) and who obtained most of their syringes from SSPs or pharmacies. CONCLUSION Syringe reuse among people who inject drugs in rural Kentucky is common. However, these data suggest that increased access to syringes from SSPs and pharmacies, as well as policy-level interventions that reduce street syringe price, might reduce syringe reuse and related harms.

Trends and correlates of abscess history among people who inject drugs in Massachusetts: A mixed methods exploration of experiences amidst a rapidly evolving drug supply. DRUG AND ALCOHOL DEPENDENCE REPORTS 2023; 8:100176. [PMID: 37753348 PMCID: PMC10518505 DOI: 10.1016/j.dadr.2023.100176] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 06/09/2023] [Accepted: 06/13/2023] [Indexed: 09/28/2023]
Abstract
Background Injection drug use poses significant risk for skin and soft tissue infections, such as abscesses. In places with endemic fentanyl and an increasingly contaminated drug supply, injecting and injection-related harms may be increasing, yet are understudied. We aimed to explore abscess prevalence, experiences, and themes among people who inject drugs (PWID) in the context of an evolving drug supply. Methods Between 2019 and 2022, we surveyed and interviewed Massachusetts- based PWID about current drug use behaviors and abscess experiences. Chi-square tests explored correlates of abscess history and trends for past-year abscess percentages over time. Transcribed interview data were analyzed to identify themes related to abscess risk and opportunities for intervention. Results Of the 297 PWID surveyed, 65.3% reported having an abscess at the injection site in their lifetime; 67.5% of these instances occurred within the last year. Reported past-year abscesses increased from 36.7% to 75.6% between 2019 and 2022. Correlates of past-year abscesses included frequent injection; methamphetamine, crack, or fentanyl use; and injection into the neck or calf. Methadone treatment was associated with significantly fewer recent abscesses. Interview data (n=151) confirmed the identified abscess risks, including syringe sharing and lack of hygienic supplies. Qualitative interviews provided additional data regarding healthcare provider stigma contributing to healthcare avoidance and the self-treatment of abscesses with adverse results. Conclusions Abscesses are an increasing concern among PWID residing in areas of high fentanyl prevalence and a contaminated drug supply. Community drug checking, overdose prevention sites, injection hygiene interventions, and improved access to care are indicated.

[PMID: 37476501 PMCID: PMC10354823 DOI: 10.1177/11782218231186065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 06/16/2023] [Indexed: 07/22/2023]
Abstract
Background Despite an increase in methamphetamine use and subsequent hospitalizations, the majority of Canadian hospitals currently lack harm reduction strategies for substance use. This can mean that people with lived experience of methamphetamine use are faced with a number of difficult decisions to make when admitted to hospital. Caring for people with lived experience of methamphetamine use can also be problematic with zero tolerance policies requiring abstinence to be maintained. This analysis set out to understand potential health care issues due to a lack of harm reduction strategies from the prospective of people with lived experience of methamphetamine use as well as health care/service professionals. Methods Based on a larger study, this secondary analysis explored issues discussed by people with lived experience of methamphetamine use and health care/service professionals regarding the challenges of providing harm reduction approaches in the hospital setting. A total of 108 individuals with lived experience of methamphetamine use completed a qualitative component of a mixed-method interview. In addition, 31 health care/service professionals participated in virtual focus groups and one-to-one interviews. Responses were analyzed using an ethnographic thematic approach. Results People with lived experience of methamphetamine use reported 3 choices upon admission: leave or avoid the hospital, stay but experience unsupported withdrawal, or stay but hide their substance usage from health care professionals. Health care/service professionals described 2 options: uphold zero tolerance that can lead to stigma and a lack of knowledge regarding addiction, or accept harm reduction but be unable to implement such strategies. This could lead to health being compromised due to policy and practice that requires abstinence. Neither group of participants described a good choice for them. Conclusion Current policy and education related to substance use needs to be revised.

Abstract
Importance US primary care practitioners (PCPs) are the largest clinical workforce, but few provide addiction care. Primary care is a practical place to expand addiction services, including buprenorphine and harm reduction kits, yet the clinical outcomes and health care sector costs are unknown. Objective To estimate the long-term clinical outcomes, costs, and cost-effectiveness of integrated buprenorphine and harm reduction kits in primary care for people who inject opioids. Design, Setting, and Participants In this modeling study, the Reducing Infections Related to Drug Use Cost-Effectiveness (REDUCE) microsimulation model, which tracks serious injection-related infections, overdose, hospitalization, and death, was used to examine the following treatment strategies: (1) PCP services with external referral to addiction care (status quo), (2) PCP services plus onsite buprenorphine prescribing with referral to offsite harm reduction kits (BUP), and (3) PCP services plus onsite buprenorphine prescribing and harm reduction kits (BUP plus HR). Model inputs were derived from clinical trials and observational cohorts, and costs were discounted annually at 3%. The cost-effectiveness was evaluated over a lifetime from the modified health care sector perspective, and sensitivity analyses were performed to address uncertainty. Model simulation began January 1, 2021, and ran for the entire lifetime of the cohort. Main Outcomes and Measures Life-years (LYs), hospitalizations, mortality from sequelae (overdose, severe skin and soft tissue infections, and endocarditis), costs, and incremental cost-effectiveness ratios (ICERs). Results The simulated cohort included 2.25 million people and reflected the age and gender of US persons who inject opioids. Status quo resulted in 6.56 discounted LYs at a discounted cost of $203 500 per person (95% credible interval, $203 000-$222 000). Each strategy extended discounted life expectancy: BUP by 0.16 years and BUP plus HR by 0.17 years. Compared with status quo, BUP plus HR reduced sequelae-related mortality by 33%. The mean discounted lifetime cost per person of BUP and BUP plus HR were more than that of the status quo strategy. The dominating strategy was BUP plus HR. Compared with status quo, BUP plus HR was cost-effective (ICER, $34 400 per LY). During a 5-year time horizon, BUP plus HR cost an individual PCP practice approximately $13 000. Conclusions and Relevance This modeling study of integrated addiction service in primary care found improved clinical outcomes and modestly increased costs. The integration of addiction service into primary care practices should be a health care system priority.

Abstract
Drug injection represents a major health problem in the US, with severe health consequences including the transmission of blood-borne infections. An examination of the most recent trends in drug injection is warranted by the fast-evolving drug epidemic and recent policy changes such as the federal funding ban on needle exchange programs. This research examines current drug injection trends, patterns, and socioeconomic and behavioral profiles of people who inject drugs (PWID). Data were derived from the 2002 to 2019 National Survey on Drug Use and Health (NSDUH). After examining the annual prevalence of drug injection since 2002, a latent class analysis was conducted to identify drug injection and other substance misuse patterns among PWID using the latest (2015-2019) NSDUH datasets. Associations between class membership and behavioral health comorbidities and treatment receipt were also assessed. The drug injection prevalence among US adults aged 18-64 increased from 0.21% in 2002/2004 to 0.36% in 2017/2019. Three distinctive groups were identified: the heroin injection group (45.2%), the methamphetamine injection group (28.0%), and the multi-drug injection group (26.8%). The methamphetamine injection group reported greater risks of experiencing serious psychological distress, suicidality, and limited substance use treatment. Special attention is needed for those who primarily injected methamphetamine. Programs to promote harm reduction and increase access to addiction treatment need to be expanded in at-risk communities while accounting for their distinct socioeconomic and drug use/misuse profiles.

Abstract
Background Outbreaks of new HIV transmission among people who inject drugs (PWID) are a major public health concern. Oral daily PrEP, has been identified as a critical addition to the biomedical toolkit for this population. However, limited research on the acceptability of long-acting injectable PrEP has been conducted with this population. Methods We conducted a cross sectional multi-site survey with 1127 participants from May 2019–February 2020 to assess the acceptability of novel PrEP regimens. We computed bivariate and multivariable logistic regressions to evaluate correlates of the outcome variable: acceptability of 3-month injectable-PrEP. SAS v.9.4 was used to conduct statistical analysis. Results Limited knowledge of or use of PrEP, past or present, was evident within the sample. Injection drug use in the past six months was significantly associated with LA injectable PrEP acceptability, with the odds of acceptability being 1.885 (CI: 1.376, 2.582) times greater than those who did not inject drugs. After adjusting for confounders, injection drug use was significantly associated with the outcome, such that the odds of acceptability of LA injectable PrEP were 1.705 (CI: 1.198, 2.427) times greater among PWID compared to those who did not inject drugs (p < 0.03). The results demonstrate acceptability (38.2%) in a durable (3-month) injectable PrEP modality among participants who also identified as PWID. Conclusions PrEP promotion efforts among PWID to increase access to long-acting injectable PrEP are necessary. Through efforts to increase acceptance and regular use of long-acting injectable PrEP, public health strategies may be able to effectively lessen chances of future HIV outbreaks among PWID.

Abstract
Purpose A reduction of 80% in new Hepatitis C virus (HCV) infection is expected by 2030. However, high HCV reinfection rates have been reported among the high-risk population. This meta-analysis aimed to assess the HCV reinfection rate after successful treatment of HIV-1 coinfected MSM populations. Methods Bibliographic databases were searched and a random-effect model was utilized to calculate the pooled HCV reinfection rate. Sub-group and meta-regression were used to explore heterogeneity among selected studies. A funnel plot and Egger's regression test were performed to estimate the publication bias. Results Sixteen studies with 9,017.2 person-years (PY) follow-up were included. The overall HCV reinfection rate following successful treatment among HIV-1-infected MSM was 5.27/100 PY (95% CI, 3.98, 6.96). Lower reinfection rates were observed in developed parts of Europe (5.28/100 PY; 95% CI, 3.73, 6.84) and North America (3.92/100 PY; 95% CI, 1.67, 6.17). Reinfection rates among people with HCV test intervals of fewer than 6 months (7.59/100 PY; 95% CI: 5.15, 10.03) were significantly higher than those with more than 6 months test interval (2.88/100 PY; 95% CI: 2.26, 3.50), with an adjusted RR of 1.86 (95% CI, 1.06, 3.13). The adjusted study factors explained 91.03% the of studies' heterogeneity. Conclusion HCV reinfection rate was high in successfully treated MSM who were coinfected with HIV-1. A shorter HCV test interval may help to explore more HCV reinfections. HCV reinfection rate studies from HIV-1 coinfected MSM in underdeveloped countries are urgently needed.

Long-term Infective Endocarditis Mortality Associated With Injection Opioid Use in the United States: A Modeling Study. Clin Infect Dis 2021; 73:e3661-e3669. [PMID: 32901815 PMCID: PMC8662770 DOI: 10.1093/cid/ciaa1346] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 09/07/2020] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND The expansion of the US opioid epidemic has led to significant increases in infections, such as infective endocarditis (IE), which is tied to injection behaviors. We aimed to estimate the population-level IE mortality rate among people who inject opioids and compare the risk of IE death against the risks of death from other causes. METHODS We developed a microsimulation model of the natural history of injection opioid use. We defined injection behavior profiles by both injection frequency and injection techniques. We accounted for competing risks of death and populated the model with primary and published data. We modeled cohorts of 1 million individuals with different injection behavior profiles until age 60 years. We combined model-generated estimates with published data to project the total expected number of IE deaths in the United States by 2030. RESULTS The probabilities of death from IE by age 60 years for 20-, 30-, and 40-year-old men with high-frequency use with higher infection risk techniques compared to lower risk techniques for IE were 53.8% versus 3.7%, 51.4% versus 3.1%, and 44.5% versus 2.2%, respectively. The predicted population-level attributable fraction of 10-year mortality from IE among all risk groups was 20%. We estimated that approximately 257 800 people are expected to die from IE by 2030. CONCLUSIONS The expected burden of IE among people who inject opioids in the United States is large. Adopting a harm reduction approach, including through expansion of syringe service programs, to address injection behaviors could have a major impact on decreasing the mortality rate associated with the opioid epidemic.

Addict Behav Rep 2021; 13:100331.

Abstract
Used an apathy composite T-score approach validated in methamphetamine-dependence. Apathy, above other factors, associated with poorer drug abstinence self-efficacy. Methamphetamine use characteristics unrelated to drug abstinence self-efficacy. Social peer pressure was riskiest situation for potential methamphetamine relapse.
Background Confidence in one’s ability to achieve and maintain drug abstinence (i.e., abstinence self-efficacy) is a strong predictor of substance use treatment outcomes. Neurobehavioral factors that may interfere with abstinence self-efficacy are less well established, particularly in methamphetamine (METH). This study investigated whether apathy, which is highly prevalent during active METH use and periods of abstinence, influences abstinence self-efficacy among METH dependent individuals. Methods Sixty-six participants with lifetime METH dependence and METH abuse/METH dependence diagnoses within the last 18 months (mean age [SD] = 39.5 years [10.7]), and no severe psychiatric or neurological diseases, completed the Methamphetamine Self-Efficacy Scale (MSES), alongside a comprehensive neurobehavioral evaluation. The MSES presents six situations that may lead to relapse and collects self-report ratings for two subscales: “Confidence” (i.e., confidence in one’s ability to abstain from using METH, or METH abstinence self-efficacy) and “Temptation” (i.e., how tempted one is to use METH) with regard to each situation. Apathy was measured using a composite T-score comprised of items and scales from three well-validated, self-report assessments. Results Multivariable linear regression found that higher Apathy T-scores were significantly associated with lower Confidence ratings (i.e., poorer METH abstinence self-efficacy; p < .05), independent of potentially relevant factors (e.g., Temptation to use METH, comorbid HIV disease, and neurocognitive impairment). Conclusions Elevated apathy may adversely impact one’s confidence to abstain from METH use. Findings highlight the importance of addressing apathy in order to improve METH abstinence self-efficacy, which may subsequently increase the likelihood of successful METH treatment outcomes.

Abstract
Persons who inject drugs are at high risk for skin and soft tissue infections. Infections range from simple abscesses and uncomplicated cellulitis to life-threatening and limb-threatening infections. These infections are predominantly caused by gram-positive organisms with Staphylococcus aureus, Streptococcus pyogenes, and other streptococcal species being most common. Although antimicrobial therapy has an important role in treatment of these infections, surgical incision, drainage, and debridement of devitalized tissue are primary. Strategies that decrease the frequency of injection drug use, needle sharing, use of contaminated equipment, and other risk behaviors may be effective in preventing these infections in persons who inject drugs.

Low Hepatitis C Reinfection Following Direct-acting Antiviral Therapy Among People Who Inject Drugs on Opioid Agonist Therapy. Clin Infect Dis 2020; 70:2695-2702. [PMID: 31346609 PMCID: PMC7456350 DOI: 10.1093/cid/ciz693] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Accepted: 07/19/2019] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Direct-acting antiviral (DAA) therapy is highly effective in people who inject drugs (PWID); however, rates, specific injection behaviors, and social determinants associated with hepatitis C virus (HCV) reinfection following DAA therapy among PWID on opioid agonist therapy (OAT) are poorly understood. METHODS PREVAIL was a randomized controlled trial that assessed models of HCV care for 150 PWID on OAT. Those who achieved sustained virologic response (SVR) (n = 141; 94%) were eligible for this extension study. Interviews and assessments of recurrent HCV viremia occurred at 6-month intervals for up to 24 months following PREVAIL. We used survival analysis to analyze variables associated with time to reinfection. RESULTS Of 141 who achieved SVR, 114 had a least 1 visit in the extension study (62% male; mean age, 52 years). Injection drug use (IDU) was reported by 19% (n = 22) in the extension study. HCV reinfection was observed in 3 participants. Over 246 person-years of follow-up, the incidence of reinfection was 1.22/100 person-years (95% CI, 0.25-3.57). All reinfections occurred among participants reporting ongoing IDU. The incidence of reinfection in participants reporting ongoing IDU (41 person-years of follow-up) was 7.4/100 person-years (95% CI, 1.5-21.6). Reinfection was associated with reporting ongoing IDU in the follow-up period (P < .001), a lack confidence in the ability to avoid contracting HCV (P < .001), homelessness (P = .002), and living with a PWID (P = .007). CONCLUSIONS HCV reinfection was low overall, but more common among people with ongoing IDU following DAA therapy on OAT, as well as those who were not confident in the ability to avoid contracting HCV, homeless, or living with a PWID. Interventions to mediate these risk factors following HCV therapy are warranted.

Abstract
BACKGROUND AND AIMS Men who have sex with men (MSM) and inject drugs are at risk for HIV infection. Although research exists on non-injection methamphetamine (meth) use and sexual risk among MSM, less is known about meth injection and its association with HIV infection among MSM who inject drugs. METHODS We analyzed data from men aged ≥18 years who reported injecting drugs and male-to-male sexual contact. Men were recruited using respondent-driven sampling, interviewed, and tested for HIV during the 2012 and 2015 cycles of National HIV Behavioral Surveillance among persons who inject drugs. We included data from 8 cities where ≥10 MSM reported meth as the primary drug injected. We assessed differences in demographic characteristics, past 12 months risk behaviors, and HIV infection between MSM who primarily injected meth and those who primarily injected another drug. RESULTS Among 961 MSM, 33.7% reported meth as the drug they injected most often. Compared to MSM who primarily injected other drugs, MSM who primarily injected meth were more likely to have had ≥5 condomless anal sex partners, have been diagnosed with syphilis, and were less likely to report sharing syringes. In multivariable analysis, injecting meth was associated with being HIV-positive (adjusted prevalence ratio 1.48; 95% confidence interval 1.08-2.03). Including number of condomless anal sex partners in mediation analysis rendered this association no longer significant. CONCLUSIONS HIV prevalence among MSM who primarily injected meth was almost 50% higher than among MSM who primarily injected other drugs, and this association was mediated by sexual risk.

Abstract
BACKGROUND People who inject drugs (PWID) take on significant risks of contracting blood-borne infection, including injecting with a large number of partners and acquiring needles from unsafe sources. When combined, risk of infection can be magnified. METHODS Using a sample of PWID in rural Puerto Rico, we model the relationship between a subject's number of injection partners and the likelihood of having used an unsafe source of injection syringes. Data collection with 315 current injectors identified six sources of needles. RESULTS Of the six possible sources, only acquisition from a seller (paid or free), or using syringes found on the street, was significantly related to number of partners. CONCLUSIONS These results suggest that sources of syringes do serve to multiply risk of infection caused by multi-partner injection concurrency. They also suggest that prior research on distinct forms of social capital among PWID may need to be rethought.

Abstract
BACKGROUND Psychiatric problems and cocaine use are associated with heightened vulnerability for HIV and Hepatitis C infections. Little is known regarding the relationship between psychiatric symptoms, psychiatric diagnoses and injection risk behaviors among cocaine users. We examined the association between psychological distress and injection material sharing among cocaine users, while accounting for comorbid anxious and mood disorders. METHODS Participants included cocaine users who inject drugs recruited in a prospective cohort study in Montreal, Canada. Diagnosis of mood and anxiety disorders in the year preceding baseline were established using the Composite International Diagnostic Interview (CIDI) questionnaire. Psychological distress based on the Kessler scale and injection material sharing in the past 3months were assessed at baseline and at each of the five follow-up visits at 3-month intervals. Statistical analyses were conducted using generalized estimation equation. RESULTS Of the 387 participants (84.5% male; 80.1%, ≥30y.o.), 35% reported severe psychological distress, 43% qualified for an anxiety disorder diagnosis and 29% for a mood disorder diagnosis at baseline. Psychological distress was not associated with any injection risk behavior when adjusting for socio-demographic and psychiatric disorders. Participants with anxiety disorders were more likely to share needle (adjusted odds ratio: 1.89, 95% CI: 1.17-3.03). Sharing of injection material other than needle was not associated with psychiatric disorders or with psychological distress in multivariate analyses. CONCLUSIONS Anxiety disorders are associated with needle sharing among cocaine users. Our results suggest the importance of screening for anxiety disorders as part of preventive interventions to decrease blood-borne viruses' transmission.

Abstract
BACKGROUND Effective treatments for cocaine use disorders remain elusive. Two factors that may be related to treatment failures are route of cocaine used and impulsivity. Smoked cocaine users are more likely to have poorer treatment outcomes compared to intranasal cocaine users. Further, cocaine users are impulsive and impulsivity is associated with poor treatment outcomes. While stimulants are used to treat Attention Deficit Hyperactivity Disorder (ADHD) and attenuate certain cocaine-related behaviors, few studies have comprehensively examined whether stimulants can reduce behavioral impulsivity in cocaine users, and none examined route of cocaine use as a factor. METHODS The effects of immediate release oral d-amphetamine (AMPH) were examined in 34 cocaine users (13 intranasal, 21 smoked). Participants had three separate sessions where they were administered AMPH (0, 10, or 20mg) and completed behavioral measures of impulsivity and risk-taking and subjective measures of abuse liability. RESULTS Smoked cocaine users were more impulsive on the Delayed Memory Task, the GoStop task and the Delay Discounting Task than intranasal cocaine users. Smoked cocaine users also reported more cocaine craving and negative mood than intranasal cocaine users. AMPH produced minimal increases on measures of abuse liability (e.g., Drug Liking). CONCLUSIONS Smoked cocaine users were more impulsive than intranasal cocaine users on measures of impulsivity that had a delay component. Additionally, although AMPH failed to attenuate impulsive responding, there was minimal evidence of abuse liability in cocaine users. These preliminary findings need to be confirmed in larger samples that control for route and duration of cocaine use.

Abstract
Hepatitis C virus (HCV) is primarily spread through risky injection practices, including sharing needles, cookers, cottons, rinse water, and the practice of backloading. An important aspect of harm reduction for people who inject drugs (PWID) is to identify factors that contribute to safer injection. Planning ability may influence risky injection practices and gender differences in factors that drive injection practices indicate a need to examine associations between planning and injection behaviors in men versus women. Data from the NEURO-HIV Epidemiologic Study was restricted to those who had ever injected in their lifetime (n=456). Impaired planning ability was assessed with the Tower of London and defined as a standardized total excess move score below the 10th percentile. We used logistic regression to estimate the gender-specific adjusted odds ratios (AOR) and 95% confidence intervals (CI) for associations between impaired planning, each injection practice, and biologically-confirmed HCV. Impaired planning ability was associated with sharing needles (AOR=2.93, 95% CI: 1.33, 6.47), cookers (AOR=3.13, 95% CI: 1.22, 8.02), cottons (AOR=2.89, 95% CI: 1.23, 6.78), rinse water (AOR=2.43, 95% CI: 1.15, 5.14), and backloading (AOR=2.68, 95% CI: 1.26, 5.70) and HCV (AOR=3.42, 95% CI: 1.03, 11.38) among men. Planning ability was not significantly associated with the injection behaviors or HCV among women, suggesting that other factors likely contribute to risky injection practices. Interventions to promote harm reduction among PWID should ascertain and strengthen planning ability. Women may have additional barriers to practicing safe injection beyond impaired planning abilities, which should also be addressed.

Abstract
Injection drug users (IDUs) are at increased risk of contracting HIV. From a clinical trial assessing an intervention to enhance the linkage of hospitalized patients to opioid treatment after discharge, we conducted multivariate analysis of baseline data from hospitalized IDUs with a history of opioid dependence (n = 104) to identify differences in factors predicting HIV drug and sex risk behaviors. Factors significantly associated with HIV drug risk were being non-Hispanic Caucasian and recent cocaine use. Being female, binge drinking, and poorer mental health were significantly associated with higher sex risk. Because factors predicting HIV sex risk behaviors differ from those predicting HIV drug risk, interventions aimed at specific HIV risks should have different behavioral and substance use targets.

Abstract
Unsafe injection practices significantly increase the risk of hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infection among injection drug users (IDUs). We examined individual and socio-environmental factors associated with unsafe injection practices in young adult IDUs in San Diego, California. Of 494 IDUs, 46.9 % reported receptive syringe sharing and 68.8 % sharing drug preparation paraphernalia in the last 3 months. Unsafe injection practices were associated with increased odds of having friends who injected drugs with used syringes, injecting with friends or sexual partners, and injecting heroin. Perceived high susceptibility to HIV and perceived barriers to obtaining sterile syringes were associated with increased odds of receptive syringe sharing, but not with sharing injection paraphernalia. Over half the IDUs reported unsafe injection practices. Our results suggest that personal relationships might influence IDUs' perceptions that dictate behavior. Integrated interventions addressing individual and socio-environmental factors are needed to promote safe injection practices in this population.

Abstract
Background There is an HIV epidemic among people who inject drugs (PWID) in Manipur and Nagaland, Northeast India. Approximately one-third of PWID across these two states are aged below 25 years, yet until now there has been no systematic investigation of the differences between the younger and older PWID. We sought to profile differences in drug use and sexual practices across age groups and to examine whether age is associated with injecting and sexual risk behaviours. Methods We used combined cross-sectional survey data collected in 2009 from two surveys involving a total of 3,362 (male) PWID in eight districts of Manipur and Nagaland. All data were collected using interviewer-administered questionnaires. Results Compared to PWID aged 35 years or older, PWID aged 18 to 24 years were more likely share needles/syringes in both Manipur (OR =1.8) and Nagaland (OR =1.6). Compared to PWID aged 35 years or older, PWID aged 18 to 24 years were almost two times as likely to draw up drug solution from a common container at their last injection in Manipur (OR =1.8). In Nagaland, PWID aged 18 to 24 years were more likely to use condoms consistently with both casual (OR =3.1) and paid (OR =17.7) female sexual partners compared to PWID aged 35 years or older. Conclusion Risky injecting practices were more common among younger PWID in both Manipur and Nagaland, while unprotected sex was more common among older PWID in Nagaland. There is a clear need to focus public health messages across different age groups.

Buckingham E, Schrage E, Cournos F. Why the Treatment of Mental Disorders Is an Important Component of HIV Prevention among People Who Inject Drugs. Adv Prev Med 2013; 2013:690386. [PMID: 23401785 PMCID: PMC3562640 DOI: 10.1155/2013/690386] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2012] [Revised: 11/06/2012] [Accepted: 12/18/2012] [Indexed: 11/17/2022] Open
Abstract
People who inject drugs are more likely to be HIV positive and to have a mental disorder than the general population. We explore how the detection and treatment of mental illness among people who are injecting drugs are essential to primary and secondary prevention of HIV infection in this population. Aside from opioid addiction, few studies have been conducted on the links between mental disorders and injection-drug use. However, independent of the injection-drug use literature, a growing number of studies demonstrate that untreated mental illness, especially depression and alcohol/substance use disorders, is associated with HIV-related risk behaviors, acquiring HIV infection, failure to access HIV care and treatment, failure to adhere to HIV care and treatment, and increased morbidity and mortality from HIV-related diseases and comorbidities. In our review of both the published literature and gray literature we found a dearth of information on models for providing care for both opioid addiction and other mental illnesses regardless of HIV status, particularly in low- and middle-income countries. We therefore make recommendations on how to address the mental health needs of HIV-positive people who inject drugs, which include the provision of opioid substitution therapy and integrated mental health, substance abuse, and HIV services.

Circular migration by Mexican female sex workers who are injection drug users: implications for HIV in Mexican sending communities. J Immigr Minor Health 2012; 14:107-15.

Abstract
Circular migration and injection drug use increase the risk of HIV transmission in sending communities. We describe female sex workers who are injection drug users' (FSW-IDUs) circular migration and drug use behaviors. Between 2008-2010, 258 migrant FSW-IDUs residing in Tijuana and Ciudad Juarez, Mexico responded to questionnaires. 24% of FSW-IDUs were circular migrants. HIV prevalence was 3.2% in circular migrants and 6.1% in non-circular migrants; 50% of circular and 75% of non-circular migrants were unaware of their HIV infection. Among circular migrants, 44% (n = 27) consumed illicit drugs in their birthplace; 74% of these (n = 20) injected drugs and one-half of injectors shared injection equipment in their birthplace. Women reporting active social relationships were significantly more likely to return home. Circular migrant FSW-IDUs exhibit multiple HIV risks and opportunities for bridging populations. Regular HIV testing and treatment and access to substance use services is critical for FSW-IDUs and their sexual/drug-using contacts.

Assessment of risky injection practices associated with hepatitis B, hepatitis C, and human immunodeficiency virus and using the blood-borne virus transmission risk assessment questionnaire.

Abstract
Risky injection practices among injection drug users (IDUs) contribute to the spread of blood-borne infections such as human immunodeficiency virus, hepatitis B, and hepatitis C. The Blood-borne Virus Transmission Risk Assessment Questionnaire (BBV-TRAQ). was developed in Australia to determine risk behaviors for specific infections. Blood testing for human immunodeficiency virus, hepatitis B, and hepatitis C was performed on all participants, and data on blood tests were linked to questionnaires. The BBV-TRAQ was administered to 242 current and former injection drug users in Long Beach, California, and the Long Beach data were compared with the original Australian data. In the comparison of the mean scores on the three subscales and total scores on the BBV-TRAQ between the samples, means for all three subscales and the total BBV-TRAQ score were significantly different, with Long Beach scores consistently lower than the Australian sample. The injecting and sexual risk subscales were significantly different across levels of AIDS risk perception for all three types of injectors; however, the other skin penetration practices subscale had no significant association with AIDS risk perception for any of the injection drug user groups. Despite recent efforts to educate injectors about the risks associated with practices captured by the other skin penetration practices subscale, such as tattooing and sharing razors, this subscale does not have an association with AIDS risk perception. injection drug users in Australia may have better access to health care, giving their self-report of infection greater validity than the California sample.

"A costly turn on": patterns of use and perceived consequences of mephedrone based head shop products amongst Irish injectors. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2012; 23:188-97. [PMID: 22342322 DOI: 10.1016/j.drugpo.2012.01.008] [Citation(s) in RCA: 71] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2011] [Revised: 01/16/2012] [Accepted: 01/19/2012] [Indexed: 11/22/2022]
Abstract
BACKGROUND Mephedrone injecting has recently been reported in Romania, Slovenia, Guernsey and Ireland. The research reported here aimed to describe the experiences of a group of Irish injecting drug users, who were injecting mephedrone based headshop products prior to the introduction of legislative controls in Ireland, with particular focus on pre- and post-legislative use, effects of injecting mephedrone, settings and contexts for injecting, polydrug use and serial drug injecting, risk perceptions and harm reduction practises. METHODS Following a predevelopment phase with a Privileged Access Interviewer, in-depth interviews using a phenomenological approach were conducted with eleven attendees of a low threshold harm reduction service. RESULTS The findings describe the abuse potential of these mephedrone based headshop products when used by intravenous injection. Although participants were aware of risks and safe injecting practises, compulsive re injecting with excessive binge use over long periods of time was common. Nasal to injection route transitions, intense paranoia, violent behaviour and aggression, emergence of Parkinson type symptomatologies (in the form of spasms and 'wobbling'), and permanent numbness in lower extremities were reported. Multi and serial drug injecting with heroin was used in efforts to manage the intense rush and avoid unpleasant comedown. Participants reported limb abscesses, vein clotting, damage and recession resulting from product toxicity, crystallisation of the products when diluted and flushing practises. Seven participants were homeless, with groin and street injecting common. Following legislative changes use of mephedrone products declined due to closure of headshops, increased street prices, concerns around contamination and the emergence of new street stimulant drugs. CONCLUSION Continued monitoring of drug displacement patterns in post legislative time frames is advised, alongside longitudinal ethnographic research to track the diffusion of mephedrone and other cathinone derivatives within injecting networks. Further investigation of the adverse health consequences of these drugs on injection is warranted.
