Patterns of and Rationale for the Co-use of Methamphetamine and Opioids: Findings From Qualitative Interviews in New Mexico and Nevada. Front Psychiatry 2022; 13:824940.

Abstract
INTRODUCTION Methamphetamine use and methamphetamine-involved deaths have increased dramatically since 2015, and opioid-related deaths now frequently involve methamphetamine. Nevada and New Mexico are states with elevated rates of opioid and methamphetamine use. In this paper, we report results from a qualitative analysis that examined patterns of methamphetamine and opioid co-use over participants' lifespan, factors that influence those patterns, and implications for health outcomes among users. METHODS Project AMPED was a multisite, mixed-methods study of methamphetamine use in Northern New Mexico and Northern Nevada. Between December 2019 and May 2020, qualitative interview participants were asked to describe their patterns of and reasons for co-administration of opioids and methamphetamine. RESULTS We interviewed 21 people who reported using methamphetamine in the past 3 months. Four primary patterns of methamphetamine and opioid co-use were identified: [1] using both methamphetamine and heroin, either simultaneously or sequentially (n = 12), [2] using methamphetamine along with methadone (n = 4), [3] using prescription opioids and methamphetamine (n = 1), and [4] using only methamphetamine (n = 4). Among those who used methamphetamine and heroin simultaneously or sequentially, motivations drew from a desire to enhance the effect of one drug or another, to feel the "up and down" of the "perfect ratio" of a goofball, or to mitigate unwanted effects of one or the other. Among those who used methamphetamine and methadone, motivations focused on alleviating the sedative effects of methadone. CONCLUSION To address the emergent trend of increasing methamphetamine-related deaths, researchers, health care professionals, and community health workers must acknowledge the decision-making processes behind co-use of opioids and methamphetamine, including the perceived benefits and harms of co-use. There is an urgent need to address underlying issues associated with drug use-related harms, and to design interventions and models of treatment that holistically address participants' concerns.

Health service utilization and experiences of stigma amongst people who inject drugs in Melbourne, Australia. J Viral Hepat 2021; 28:1738-1743.

Abstract
Whilst the testing and treatment of people who inject drugs (PWID) in Australia is a priority for local hepatitis C (HCV) elimination efforts, perceived stigma related to injecting drug use (IDU) has been identified as a major barrier for PWID engaging in health services. We used data from the EC Experience cohort study to explore associations between IDU-related perceived stigma and the number of different health services accessed by PWID in Melbourne, Australia. Data from the baseline questionnaire were used. Primary outcome was self-reported experience of stigma due to IDU (never, rarely, sometimes, often, always) in the previous 12 months. An ordinal logistic regression model assessed the association between stigma experienced and the number of different health services used (1-2, 3-4, 5-6, 7-10 different services) adjusted for recent IDU and key socio-demographics. Between September 2018 and February 2020, 281 participants were recruited from four health services. Sixty-nine per cent were male, median age was 42, 83% reported past-month IDU, 34% had never tested/tested >12 months, 8% tested negative <12 months, 43% were HCV-positive but not treated and 16% had been treated. Those accessing 5-6 services had 2.2 times greater odds of experiencing stigma (95% CI 0.86-6.65) compared with those using <5 services and those reporting 7-10 services had 2.43 times greater odds of experiencing stigma (95% CI 0.85-6.92) compared with those accessing <7 services. In conclusion, experiences of stigma may not necessarily be a barrier for PWID to access health services, but high rates of health service use may further expose, exacerbate or exaggerate stigma amongst PWID. Further examination of how stigma may be in/directly impact on hepatitis C treatment uptake is important and place-based interventions aimed at reducing stigma experienced by PWID may be needed.

J Viral Hepat 2021; 28:1744-1750. [PMID: 34525228 DOI: 10.1111/jvh.13614] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 09/06/2021] [Accepted: 09/08/2021] [Indexed: 01/03/2023]
Abstract
The efficacy of direct-acting antivirals (DAA) provides an excellent opportunity to scale up HCV diagnosis and treatment, achieving the WHO target of HCV elimination by 2030. However, HCV reinfection among people who inject drugs (PWID) remains a concern and may impede elimination efforts. We assessed reinfection rates among PWID across six specialized treatment pathways, following DAA-based and interferon-based therapies in Tayside, Scotland. Data were collected retrospectively for every treatment episode that resulted in a sustained viral response (SVR) after undergoing treatment. Reinfection rates were calculated for each treatment pathway: hospital outpatient clinic; community pharmacy; drug treatment outreach; prison clinic; nurse-led outreach clinic; and injection equipment provision site. Reinfection is defined as a positive RNA test result after SVR. Incidences of reinfection are expressed in 100 person-years (PYs). In total, 916 treatment episodes met selection criteria. Of these, 100 reinfections were identified, generating an overall reinfection rate of 5.27 per 100 PYs (95%CI: 4.36-6.38). The hospital outpatient clinic had the lowest reinfection incidence (1.81 per 100 PYs, 95%CI: 1.11-2.93), with the injection equipment provision site treatment pathway having the highest reinfection incidence (19.89 per 100 PYs, 95%CI: 14.91-26.54). The incidence of reinfection among those treated with interferon-based therapies and those treated with DAA-based therapies was 4.93 per 100 PYs (95%CI: 3.97-6.11) and 7.17 per 100 PYs (95%CI: 4.75-10.82), respectively. Specialized treatment pathways in Tayside yield varying reinfection incidence rates, with different subpopulations of patients at varying risk of reinfection post-SVR. Results suggest that resources should be targeted at the injection equipment provision site pathway in order to reduce the incidence of reinfection and achieve elimination targets. The study found comparable rates of reinfection following interferon-based and DAA-based therapies, providing support for widening access to treatment services.

Association Between Opioid Agonist Therapy and Testing, Treatment Uptake, and Treatment Outcomes for Hepatitis C Infection Among People Who Inject Drugs: A Systematic Review and Meta-analysis. Clin Infect Dis 2021; 73:e107-e118. [PMID: 32447375 PMCID: PMC8246796 DOI: 10.1093/cid/ciaa612] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Accepted: 05/20/2020] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND People who inject drugs (PWID) experience barriers to accessing testing and treatment for hepatitis C virus (HCV) infection. Opioid agonist therapy (OAT) may provide an opportunity to improve access to HCV care. This systematic review assessed the association of OAT and HCV testing, treatment, and treatment outcomes among PWID. METHODS Bibliographic databases and conference presentations were searched for studies that assessed the association between OAT and HCV testing, treatment, and treatment outcomes (direct-acting antiviral [DAA] therapy only) among PWID (in the past year). Meta-analysis was used to pool estimates. RESULTS Of 9877 articles identified, 22 studies conducted in Australia, Europe, North America, and Thailand were eligible and included. Risk of bias was serious in 21 studies and moderate in 1 study. Current/recent OAT was associated with an increased odds of recent HCV antibody testing (4 studies; odds ratio (OR), 1.80; 95% confidence interval [CI], 1.36-2.39), HCV RNA testing among those who were HCV antibody-positive (2 studies; OR, 1.83; 95% CI, 1.27-2.62), and DAA treatment uptake among those who were HCV RNA-positive (7 studies; OR, 1.53; 95% CI, 1.07-2.20). There was insufficient evidence of an association between OAT and treatment completion (9 studies) or sustained virologic response following DAA therapy (9 studies). CONCLUSIONS OAT can increase linkage to HCV care, including uptake of HCV testing and treatment among PWID. This supports the scale-up of OAT as part of strategies to enhance HCV treatment to further HCV elimination efforts.

Abstract
BACKGROUND People who inject drugs are at greater risk of hepatitis C virus (HCV) infection and hospitalisation, yet admissions are not utilised for HCV treatment initiation. We aimed to assess the extent to which people with HCV notification, including those with evidence of recent drug dependence, are hospitalised while eligible for direct-acting antiviral (DAA) therapy, and treatment uptake according to hospitalisation in the DAA era. METHODS We conducted a longitudinal, population-based cohort study of people living with HCV in the DAA era (March 2016-December 2018) through analysis of linked databases in New South Wales, Australia. Kaplan Meier estimates were used to report HCV treatment uptake by frequency, length, and cause-specific hospitalisation. RESULTS Among 57,467 people, 14,938 (26%) had evidence of recent drug dependence, 50% (n=7,506) of whom were hospitalised while DAA eligible. Incidence of selected cause-specific hospitalisation was highest for mental health-related (15.84 per 100 person-years [PY]), drug-related (15.20 per 100PY), and injection-related infectious disease (9.15 per 100PY) hospitalisations, and lowest for alcohol use disorder (4.58 per 100PY) and liver-related (3.13 per 100PY). 65% (n=4,898) of those hospitalised had been admitted >2 times and 46% (n=3,437) were hospitalised >7 days. By the end of 2018, DAA therapy was lowest for those hospitalised >2 times, for >7 days, and those whose first admission was for injection-related infectious disease, mental health disorders, and drug-related complications. CONCLUSIONS Among people who have evidence of recent drug dependence, frequent hospitalisation-particularly mental health, drug, and alcohol admissions-presents an opportunity for engagement in HCV care.

Abstract
INTRODUCTION This paper aims to describe cocaine use, markets and harms in Australia from 2003 to 2019. METHODS Outcome indicators comprised prevalence of use from triennial household surveys; patterns of use from annual surveys of sentinel samples who use stimulants; and cocaine-related seizures, arrests, hospitalisations, deaths and treatment episodes. Bayesian autoregressive time-series analyses were conducted to estimate trend over time: Model 1, no change; Model 2, constant rate of change; and Model 3, change over time differing in rate after one change point. RESULTS Past-year population prevalence of use increased over time. The percentage reporting recent use in sentinel samples increased by 6.1% (95% credible interval [CrI95% ] 1.2%,16.9%; Model 3) per year from around 2017 (48%) until the end of the series (2019: 67%). There was a constant annual increase in number of seizures (count ratio: 1.1, CrI95% 1.1,1.2) and arrests (1.2, CrI95% 1.1,1.2), and percentage reporting cocaine as easy to obtain in the sentinel samples (percent increase 1.2%, CrI95% 0.5%,1.8%; Model 2). Cocaine-related hospitalisation rate increased from 5.1 to 15.6 per 100 000 people from around 2011-2012 to 2017-2018: an annual increase of 1.3 per 100 000 people (CrI95% 0.8,1.8; Model 3). While the death rate was low (0.23 cocaine-related deaths per 100 000 people in 2018; Model 2), treatment episodes increased from 3.2 to 5.9 per 100 000 people from around 2016-2017 to 2017-2018: an annual increase of 2.9 per 100 000 people (CrI95% 1.6,3.7; Model 3). DISCUSSION AND CONCLUSIONS Cocaine use, availability and harm have increased, concentrated in recent years, and accompanied by increased treatment engagement.

Abstract
Injecting alone increases the risk of a fatal overdose. We examined the extent of such behavior in a sample of people who inject drugs (PWID) and the typical characteristics of those injecting alone at least once during the past four weeks. A cross-sectional study. PWID recruited from the street and from low-threshold services in seven Norwegian cities in September 2017 (n = 359). Associations between characteristics and injecting alone were examined using logistic regression analysis. The independent variables were gender (female/male), age, having received overdose-prevention education (no/yes), and, in the past four weeks; homelessness/shelter use (no/yes), in opioid substitution treatment (no/yes), injecting ≥ four days a week (no/yes), and substances injected (opioids only/opioids and other/other only/central stimulants (CS) only/CS and other/CS and opioids/CS, opioids and other). The adjusted odds ratios (aOR) and 95% Confidence Intervals (CI) were reported. Of the 359 PWID, 84.4% reported having injected alone. Males were more likely than females to inject alone (aOR = 1.88 95% CI 1.00-3.54). Furthermore, those injecting frequently (aOR = 1.99 95% CI 1.02-3.86) and those injecting multiple substances (CS, opioids and other) (aOR = 2.94 95% CI 1.01-8.58) were more likely to inject alone compared to those injecting less frequently and opioids only. Although not statistically significant, the effect sizes in the logistic regression models suggest that polysubstance use may be driven by CS use. Injecting alone was common in our sample of PWID, and male gender, frequent injecting and polysubstance injecting were associated with this behavior.

Abstract
Drugged bodies are commonly depicted as passive, suffering and abject, which makes it hard for them to be known in other ways. Wanting to get closer to these alternative bodies and their resourcefulness for living, I turned to body-mapping as an inventive method for telling different kinds of drug-using stories. Drawing on a research project with people who inject heroin and crack cocaine in London, UK, I employed body-mapping as a way of studying drugged bodies in their relation to others, human and non-human, in the injecting event. I invited participants to draw their bodies in describing these otherwise hard-to-articulate experiences. Following Donna Haraway, I conceptualise body-mapping as a more-than-human mode of storytelling where different kinds of bodies can be known. Here, I look at three such bodies - sensing-bodies, temporal-bodies and environment-bodies - and argue that it is through being able to respond to such bodies that more hospitable ways of living with drugs can become possible.

Abstract
BACKGROUND In many settings, recent or prior injection drug use remains a barrier to accessing direct-acting antiviral treatment (DAA) for hepatitis C virus (HCV) infection. We examined patterns of drug and alcohol use and injection equipment sharing among people with recent injecting drug use or receiving opioid agonist treatment (OAT) during and following DAA-based treatment. METHODS SIMPLIFY and D3FEAT are phase 4 trials evaluating the efficacy of DAA among people with past 6-month injecting drug use or receiving OAT through a network of 25 international sites. Enrolled in 2016-2017, participants received sofosbuvir/velpatasvir (SIMPLIFY) or paritaprevir/ritonavir/dasabuvir/ombitasvir ± ribavirin (D3FEAT) for 12 weeks and completed behavioral questionnaires before, during, and up to 2 years posttreatment. The impact of time in HCV treatment and follow-up on longitudinally measured longitudinally measured behaviors was estimated using generalized estimating equations. RESULTS At screening, of 190 participants (mean age, 47 years; 74% male), 62% reported any past-month injecting 16% past-month injection equipment sharing, and 61% current OAT. Median alcohol use was 2 (Alcohol Use Disorders Identification Test-Consumption; range, 1-12). During follow-up, opioid injecting (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.92-0.99) and sharing (OR, 0.87; 95% CI, 0.80-0.94) decreased, whereas no significant changes were observed for stimulant injecting (OR, 0.98; 95% CI, 0.94-1.02) or alcohol use (OR, 0.99; 95% CI, 0.95-1.04). CONCLUSIONS Injecting drug use and risk behaviors remained stable or decreased following DAA-based HCV treatment. Findings further support expanding HCV treatment to all, irrespective of injection drug use. CLINICAL TRIALS REGISTRATION SIMPLIFY, NCT02336139; D3FEAT, NCT02498015.

Abstract
Hepatitis C, caused by the hepatitis C virus (HCV), is a major public health issue in Russia. The aim of our study was to assess the seroprevalence of markers of HCV exposure and factors associated with HCV seropositivity among the general population aged 18–39 years in the city of Arkhangelsk, Northwest Russia. A social research agency applied a quota sampling method to recruit study participants using cell phone numbers. All participants (n = 1243) completed a self-administered questionnaire and provided a blood sample. Sixty-five participants (5.2%, 95% confidence interval [CI] 4.9–5.5) tested positive for HCV IgM+G antibodies, and of these, 55 (84.6%) did not know that they were exposed to HCV. In multivariable logistic regression analysis, HCV seropositivity was significantly associated with older age, a history of injecting drug use, and having ever received a blood transfusion. To reach the goal of the World Health Organisation’s Global Health Sector Strategy on Viral Hepatitis, regional preventive programmes should include measures to reduce injecting drug use as well as scaling up harm-reduction and treatment programs for drug addicts.

Abstract
OBJECTIVE Patients with a severe mental illness have higher rates of infection with blood-borne viruses (BBVs) but are less likely to access testing and treatment. Enhanced testing of this population is therefore warranted. METHODS In this single centre, prospective study, we sought to offer testing for BBVs to all patients who attended an appointment in the clozapine clinic (CC) over a six-month period. Those who consented were tested for HIV antigen/antibody, hepatitis C virus (HCV) antibody and hepatitis B virus surface antigen (HBsAg). RESULTS During the study period, 192 patients attended an appointment, of which 164 were offered testing. Of those, 134 (81.7%) accepted and 30 declined. Among patients who agreed to be tested, results were returned for 96 (71.6%). There were no positive results for HBsAg or HIV. Seven patients (7.2%) were positive for HCV antibody. Of those, three were newly identified exposures of which two were found to be chronically infected and were referred for treatment. CONCLUSION A routine offer of BBV testing for people with severe mental illness in the outpatient setting is feasible and may detect treatable infections.

Abstract
Background Chemsex, the use of select psychoactive drugs to enhance sexual experience, typically among men who have sex with men (MSM), is associated with sexual behaviours with higher STI risk. Understanding patterns of chemsex among MSM as well as the characteristics and sexual health service engagement of chemsex participants is important for developing interventions. Methods Between 5/2016 to 5/2017, 3933 MSM completed an online survey, recruited in sexual health clinics (SHCs) in England (n=421) and via four social networking/dating apps (n=3512). We described patterns of chemsex in the past year and used multivariable logistic regression to investigate differences in demographics and sexual behaviours by chemsex history. We described history of SHC attendance and STI test in the past year among app-recruited chemsex participants. Results Chemsex in the past year was reported by 10% of respondents; 19% of SHC-recruited and 9% of app-recruited. Among chemsex participants, 74% had used ≥2 chemsex drugs. In the multivariable model, MSM engaging in chemsex had a raised odds of being HIV-positive (adjusted OR (aOR): 3.6; 95% CI 2.1 to 6.1), aged 30–44 (aOR 1.5 vs <30 years; 95% CI 1.0 to 2.1), being born outside the UK and having engaged in higher risk sexual behaviours in the past 3 months. Chemsex participants also had higher odds of condomless anal sex with partners of different or unknown HIV status, but only among HIV-negative/untested. In the past year, 66% of app-recruited chemsex participants had attended a SHC and 81% had had an STI test. Conclusion One in 10 MSM recruited through community and clinical settings across England had engaged in chemsex in the past year. Those that did appear to be at greater STI risk but engaged more actively with sexual health services. This highlights the need and opportunity for chemsex-related services in SHCs and robust referral pathways to drug treatment services.

Abstract
INTRODUCTION AND AIMS Gay and bisexual men (GBM) who inject drugs are disproportionately affected by human immunodeficiency virus (HIV) because of dual transmission risks. New Zealand has a progressive history of harm reduction and was the first country to publicly fund needle exchange programs in 1988 for people who inject drugs (PWID). We combine national HIV epidemiological and bio-behavioural surveillance data to understand HIV risk among this subpopulation. DESIGN AND METHODS We examine trends in new HIV diagnoses 1996-2018 by mode of transmission, and compare HIV cases attributed to sex between men (MSM-only), MSM/injecting drug use (IDU) and IDU-only. IDU among GBM in a national HIV behavioural surveillance survey was also examined. We compare GBM by IDU status (never, 'recent', previous) and identified predictors of recent IDU. RESULTS Of 1653 locally-acquired HIV diagnoses 1996-2018, 77.4% were MSM-only, 1.5% MSM/IDU, 1.4% IDU-only and 14.2% heterosexual mode of transmission. On average, just one HIV diagnosis attributed to MSM/IDU and IDU, respectively, occurred per annum. MSM/IDU cases were more likely than MSM-only cases to be indigenous Māori ethnicity. Of 3163 GBM survey participants, 5.4% reported lifetime IDU and 1.2% were recent IDU. Among GBM, HIV positivity was 20% among recent IDU and 5.3% among never injectors. Predictors of recent IDU were: age under 30; more than 20 male partners; female partner; condomless intercourse; HIV positivity. DISCUSSION AND CONCLUSION New Zealand has averted high endemic HIV rates seen among GBM and PWID in other countries and results have been sustained over 30 years.

Blood donation amongst people who inject drugs in Australia: research supporting policy change. Vox Sang 2020; 115:162-170. [PMID: 32023663 DOI: 10.1111/vox.12891] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 12/23/2019] [Accepted: 01/07/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND OBJECTIVES Until recently, people in Australia with a history of injection drug use (IDU) were deferred indefinitely from donating blood. Knowledge gaps regarding policy non-compliance and the prevalence of blood donation practices amongst people who inject drugs (PWID) precluded changes to this policy. We sought to address these gaps and to estimate the additional risk to Australia's blood supply associated with changing the indefinite deferral policy to 1 or 5 years since last injecting episode. MATERIALS AND METHODS Data on blood donation amongst PWID were collected from 1853 interviews across two Australian studies of PWID conducted during 2015/16. Mathematical modelling was used to estimate the additional risk of hepatitis C (HCV)-infected window period collections as a result of changing the deferral policy. RESULTS A very few (2-4%) study participants reported ever donating blood after ≥1 IDU episode. Changing the deferral policy from indefinite to 1 or 5 years was estimated to result in an additional 0·00000070 (95%CI: 0·00000033-0·00000165) or 0·00000020 (95%CI: 0·00000008-0·00000041) HCV-positive window period collections per year, respectively. CONCLUSION Changing Australia's indefinite deferral period to 1 or 5 years since last injecting episode poses a negligible increase in the risk of HCV-infected window period collections from blood donors with a history of IDU. Our results informed a successful submission to the Australian regulator to change the deferral period from indefinite to 5 years since last injecting episode, a policy which came into effect in September 2018.

Abstract
Background: The bulk of research on adoption of injecting is from Europe and America, despite the existence of syndemics of drug injecting, HIV, and viral hepatitis globally. Objectives: This study explores adoption and continuation of injecting drug use. Methods: The study draws on in-depth interviews with 41 (n = 41) current male and female people who inject drugs recruited via snow-ball sampling in Uyo, Nigeria. A thematic and descriptive analysis was undertaken informed by the risk environment framework and focused on accounts of the factors influencing the process. Results: Accounts emphasized injecting adoption and continuation as a process influenced by individual, social, and structural factors within the risk environment, including concerns for pleasure/efficiency, prestige, exposure to/support for injecting within peer and sexual relationships, availability and purity of drugs, and dependence and increased cost of drug use. Conclusions/implications: Findings highlight the need to prevent adoption of injecting, reduce prevalence of injecting, and promote safe injecting through multi-level interventions, including peer-driven education, drug treatment services, needle and syringe distribution, oral drug substitution, and law enforcement targeting drug suppliers. The need for equivalent pleasure with minimal risk points to the strategic importance of peer interactions for inculcating new understandings of drug use and pleasure.

Abstract
BACKGROUND Intensive use of illicit drugs in general and drug injecting in particular are associated with higher somatic co-morbidity, especially of infectious aetiology. The treatment participation of drug users is complicated by a number of barriers. MATERIAL AND METHODS At the end of 2013, a cross-sectional questionnaire study was conducted on a non-random sample of 240 drug users (188 men and 52 women) recruited in low-threshold drug services in Prague based on their willingness to participate in the study. Drug injecting sometimes in their lifetime was reported by 237 respondents (98.8%), injecting drug use in the last 12 months by 232 (96.7%), and injecting drug use in the last 30 days by 228 (95.0%). The questionnaire included 38 of the 59 original items from the Barriers to Treatment Inventory (BTI). Factor analysis of these items was performed. In addition to the questionnaire survey, two focus groups with a total of 14 clients were carried out. RESULTS The factor analysis resulted in a 5-factor model that was fed with 23 BTI items. The factors identified can be interpreted as: (1) difficulty entering treatment due to additional responsibilities (e.g. children, family, work, etc.), (2) previous poor treatment experience, fear and concerns about the treatment or negative attitudes of staff, (3) financial difficulties and formal barriers (health insurance debts, problems with the law, etc.), (4) concerns that entering treatment will be too complicated and difficult, (5) distrust of the treatment's ability to improve the client's life situation. The results of the focus groups have shown that drug users face stigmatization and discrimination in healthcare facilities. CONCLUSION The access to treatment of infectious and other somatic co-morbidity in drug users is complicated by a number of barriers, which largely arise from the lifestyle and socio-economic situation associated with drug use and from negative experiences with the attitude of medical staff. Healthcare professionals should actively identify and respond to barriers to care among drug users by taking appropriate measures in the context of a multidisciplinary approach and cooperation.

Abstract
From July to August 2016, 4 homeless people who injected drugs (PWID) with acute or recent hepatitis C virus (HCV) infection were reported in Belfast. A multidisciplinary team including public health, homeless and addiction services undertook an investigation to identify risk behaviours and interrupt transmission chains. Recent HCV cases were defined as negative test within the previous year, or reported injecting for less than 1 year; acute cases had tested negative within the previous 6 months. Contacts in the injecting networks of cases were identified for testing. We undertook a cross-sectional survey using structured questionnaires to elicit risk behaviours for PWID and compare behaviours between self-reported hepatitis C positive and negative subjects. During the outbreak investigation until December 2017, 156 PWID were tested and 45 (29%) cases identified, including 7 (16%) recent and 13 (29%) acute infections. 68 PWID, including 12 cases, were interviewed. All respondents reported using heroin, with 76% injecting once or more daily. Sharing was reported for spoons (58%) and filters (53%), but also needles (27%) and syringes (29%). Hepatitis C positive individuals had higher odds to be injecting in public toilets (AOR 17, 95% CI 0.71-400, P < .05) when compared with hepatitis C negative individuals. Hepatitis C positive individuals were more likely to inject in public spaces, but all respondents indicated concerning risk behaviours. We recommend active surveillance with ongoing testing, expanding existing harm reduction programmes and access to bespoke services.

Abstract
INTRODUCTION AND AIMS Non-fatal opioid overdose (NFOO) predicts future fatal opioid overdose and is associated with significant morbidity. There is limited literature on the rates and risk factors for NFOO in people who inject drugs (PWID) from India. We aimed to study the rates of NFOO and documented risk factors for NFOO, as well as knowledge-level of NFOO among PWID from India. DESIGN AND METHODS Community-based, cross-sectional and observational study. We interviewed 104 adult male participants receiving HIV prevention services. Drug use patterns, rates of NFOO and opioid overdose risk factors, knowledge about opioid overdose and its management were assessed. RESULTS The mean age of the participants was 27.9 years. The most common opioid used for injecting was heroin followed by buprenorphine. About 45% (n = 47) participants had experienced an opioid overdose at least once in their lifetime. Around 25% (n = 26) participants had overdosed in the past year, while 21% (n = 22) participants had overdosed within the past 3 months. The majority had risk factors that could predispose them to NFOO. No participant was aware of the use of naloxone for opioid overdose. DISCUSSION AND CONCLUSION The rates of NFOO as well as risk factors for overdose among PWID from India are high, with poor knowledge on overdose management. There is urgent need for a program to prevent and manage opioid overdose among PWID in India.

Abstract
Hepatitis C virus (HCV) in the U.S. has tripled in the prior five years, and injecting drug use is the primary risk for HCV, with up to 90% of older and former people who inject drugs (PWIDs) testing positive. Laboratory testing of HCV for any PWIDs is the gold standard, however many PWIDs lack access to health treatment or services. Identifying risks of HCV via a data science approach would aid community health workers (CHW) to rapidly link those most at risk of infection with treatment. This study employed a data-science approach to determine the strongest risk factors of HCV in a sample of Mexican-Americans WIDs n = 221 (96 negative/125 positive). Data included 238 demographic and psychosocial predictors. A Random Forest machine learning algorithm demonstrated significant prediction improvement over baseline no information rate comparison. Strongest risks for positive HCV included sharing drug-use equipment and younger age at first heroin use; receiving drug-education during incarceration was protective. A ROC curve fit to the prediction yielded an area under the curve of 0.77. Predictive variables of HCV in the present analysis can be obtained via screening by CHW. Identification of patients most at risk of HCV within community settings can maximize treatment utilization.

Abstract
Background Unsafe injecting drug use is a documented risk factor for the transmission of human immunodeficiency virus infection. Harm reduction strategy aims at reducing this deleterious consequence. Objectives To study the prevalence and predictors of injecting as well as sexual risk behavior among male injecting drug users (IDUs). Methods A cross-sectional study was conducted among 250 male IDUs from January 2017 to March 2018. Risk behavioral data were collected after obtaining informed consent of the study participants. This included information on sharing, reusing needles/injections, and sexual behavior. Descriptive statistics and logistic regression model was run using the Epi Info software version 7.2 for Windows. Results In the past one month, 25.3% had shared needles/syringes by either borrowing or lending or both. Inconsistent condom use during sexual intercourse with a regular, casual, and paid sex partner was practiced by 64.7% (77/119), 65.8% (48/73), and 45.0% (18/40), respectively. The binary logistic regression analysis revealed that unsafe injecting drug behavior was higher among daily users: (OR = 3.0 [1.3-6.6]) and comparatively lower among those who preferred to avail needles/syringes from Needle Syringe Exchange Program (OR = 0.4 [0.2-0.9]); as compared to their counterparts. Conclusions The findings suggest that IDUs in the study area are engaging in risk behaviors. Behavior change communication and harm reduction strategy should be strengthened.

Abstract
PURPOSE Chemsex-related drug use (CDU) is an escalating public health issue among men who have sex with men (MSM), associated with significant physical, biomedical and psychosocial harm. Few interventions exist to help MSM engaging in chemsex and little data exist on which to build. This cross-sectional analysis, using data from Antidote, the UK's only lesbian, gay, bisexual, and transgender specialist drug service, aims to remedy this paucity of data. METHODS Modified Poisson regression was used to assess associations between CDU and a range of health outcomes; CDU+ subanalysis disaggregated MSM by primary chemsex drug of concern; and HIV+ subanalysis investigated whether CDU was associated with self-reported treatment adherence, HIV seroconversion and other HIV-specific issues. FINDINGS Compared with CDU- MSM, MSM presenting for CDU were more likely to be HIV+, current or previous injectors, to have used postexposure prophylaxis in the last year, and have had ≥6 sexual partners in the last 90 days, though less likely to be hazardous alcohol consumers or to have experienced previous suicidal ideation (all p<0.0005). CDU+ subanalysis revealed health outcome differences-those selecting mephedrone were less likely to be hepatitis C+, HIV+, current or previous injectors, or to have experienced previous suicidal ideation (all p<0.0005), whereas those selecting methamphetamine were more likely (all p<0.0005, except suicidal ideation p=0.009). IMPLICATIONS This analysis shows MSM presenting for CDU are a heterogeneous high-risk population with unmet health needs. There is a need for standardised chemsex surveillance and for improved intersectorial working between sexual health and drug treatment services. Future research should investigate typological differences between MSM presenting for CDU. ORIGINALITY/VALUE To date, this is the world's largest analysis of MSM seeking treatment for CDU. Further, the publication of 'real-world' service data is a valuable addition to the literature alongside surveys and recruited studies.

Abstract
To achieve WHO hepatitis C virus (HCV) elimination targets by 2030, mathematical models suggest there needs to be significant scale-up of treatment among people who inject drugs (PWID). We tested whether people who actively inject drugs can be recruited and treated successfully through a community needle and syringe programme (NSP), and assessed rates of re-infection. 105 HCV RNA positive participants were enrolled prospectively. Participants were recruited from the largest NSP in Dundee over 42 months. 94/105 individuals commenced treatment. Genotype 1 (G1) individuals (n = 37) were treated with peg-interferon+ribavirin+Simepravir/Telaprevir. Genotype 2/3 (G2/3) (n = 57) received peg-interferon+ribavirin. Weekly study visits took place within the NSP. Mean age of participants was 34.0 years (SD 6.9), 71.3% (61/94) were male. One in five (20/94) participants were homeless. 68.1% (64/94) were on OST (opiate substitution therapy) at enrolment; participants injected median 6.5 times/wk. In terms of clinical outcomes, >80% treatment adherence was 71.3% (67/94). There was no difference in SVR-12 rates by genotype: 81.0% (30/37) for G1 and 82.5% (47/55) for G2/3. At 18 months post-treatment, 15/77 participants were reinfected, followed up over 69.8 person-years, yielding a re-infection rate of 21.5/100 person-years (95% CI 13.00-35.65). This trial demonstrates that HCV treatment can be delivered successfully to the target population of treatment as prevention strategies. We report higher rates of re-infection than existing estimates among PWID. Scale-up of HCV treatment should be pursued alongside a comprehensive programme of harm reduction interventions to help minimize re-infection and reduce HCV transmission.

Abstract
Background: Ukraine's perinatally HIV-infected (PHIV) young people are ageing into adolescence/young adulthood and, alongside those with horizontally-acquired HIV infections, require transitional and other support services. We aimed to map this population and policies/service provision at specialist HIV centres, to inform future service development. Methods: A national survey was conducted of 28 HIV/AIDS centres on number, characteristics (age group, HIV acquisition mode) and care setting (paediatric/adult) of 10-24 year olds in HIV care in each of 24 regions in January 2016. Information was collected on policies/service provision at each centre. Results: Of 13,286 young people aged 10-24 years registered for HIV care nationally in Ukraine in January 2016, 1,675 were aged 10-18 years. Three-quarters of ≤19 year olds were PHIV, while 72% of 20-24-year-olds had sexually-acquired infection. Five regions accounted for two-thirds of 10-18 year olds in paediatric and 85% of 19-24 year olds in adult services. In 2015, 97 young people transitioned from paediatric to adult services nationally, typically at 18 years although with flexibility in timing at 17/28 centres. At 27/28 centres, horizontally HIV-infected young people aged <18 years began their HIV care in paediatric services sometimes (5) or always (22). Transition support most commonly consisted of a joint appointment with paediatrician and adult doctor, and support from a psychologist/social worker (both at 24/28 centres). Only 5/28 centres offered routine HIV care during the evening or weekend, and availability of integrated sexual/reproductive health and harm reduction services was uneven. Of 16/28 centres selectively following-up patients who did not attend for care, 15 targeted patients in paediatric services. Conclusions: Heterogeneity in the population and in service availability at the main regional/municipal HIV/AIDS centres has implications for potential structural barriers to HIV care, and development of services for this group.
