Excellent hepatitis C virus cure rates despite increasing complexity of people who use drugs: Integrated-Test-stage Treat study final outcomes.

Achieving hepatitic C virus (HCV) elimination requires linking people who use drugs (PWUD) into care. We report final direct-acting antivirals (DAAs)-based outcomes from the Integrated-Test-stage -Treat (ITTREAT) study. Project ITTREAT (2013-2021), based at an addiction centre, was a 'one-stop' service with innovative linkage to care strategies. Primary outcome was sustained virological response (SVR12) (intention to treat ITT) including whether individuals were recruited in first (period 1) versus last four (period 2 included the COVID-19 pandemic) years of the study. Number recruited were n = 765, mean age 40.9 ± 10.1 years, 78% males, history of current/past injecting drug use (IDU) and alcohol use being 77% and 90%, respectively. Prevalence of a positive HCV PCR was 84% with 19% having cirrhosis. Comparing those recruited in period 2 versus period 1, there was increasing prevalence of IDU, 90% versus 72% (p < .001); homelessness, 67% versus 50% (p < .001); psychiatric diagnosis, 84% versus 50% (p < .001); overdose history 71% versus 31% (p < .001), receiving opioid agonist treatment (OAT) 75% versus 52% (p < .001) and comorbidity 44% versus 25% (p < .001). Of those treated with DAAs (n = 272), ITT SVR rates were 86% (95% CI: 81%-90%), being similar in period 2 versus period 1. Predictors of non-SVR were receiving OAT (OR 0.33, 95% CI: 0.12-0.87, p = .025) and ≥80% adherence (OR 0.01, 95% CI: 0.003-0.041, p < .001). Reinfection rates period 2 versus period 1 (per 100 person-years) were 1.84 versus 1.70, respectively. In the treated cohort, mortality was 15%, being mostly drug-related. Despite increasing complexity of PWUD, high SVR12 rates are achievable with use of OAT and good adherence.

REPAIRS Delphi: A UK and Ireland Consensus Statement on the Management of Infected Arterial Pseudoaneurysms Secondary to Groin Injecting Drug Use.

OBJECTIVE: Consensus guidelines on the optimal management of infected arterial pseudoaneurysms secondary to groin injecting drug use are lacking. This pathology is a problem in the UK and globally, yet operative management options remain contentious. This study was designed to establish consensus to promote better management of these patients, drawing on the expert experience of those in a location with a high prevalence of illicit drug use. METHODS: A three round modified Delphi was undertaken, systematically surveying consultant vascular surgeons in the UK and Ireland using an online platform. Seventy five vascular surgery units were invited to participate, with one consultant providing the unit consensus practice. Round one responses were thematically analysed to generate statements for round two. These statements were evaluated by participants using a five point Likert scale. Consensus was achieved at a threshold of 70% or more agreement or disagreement. Those statements not reaching consensus were assessed and modified for round three. The results of the Delphi process constituted the consensus statement. RESULTS: Round one received 64 (86%) responses, round two 59 (79%) responses, and round three 62 (83%) responses; 73 (97%) of 75 units contributed. Round two comprised 150 statements and round three 24 statements. Ninety one statements achieved consensus agreement and 15 consensus disagreement. The Delphi statements covered sequential management of these patients from diagnosis and imaging, antibiotics and microbiology, surgical approach, wound management, follow up, and additional considerations. Pre-operative imaging achieved consensus agreement (97%), with computerised tomography angiography being the modality of choice (97%). Ligation and debridement without arterial reconstruction was the preferred approach at initial surgical intervention (89%). Multidisciplinary management, ensuring holistic care and access to substance use services, also gained consensus agreement. CONCLUSION: This comprehensive consensus statement provides a strong insight into the standard of care for these patients.

The influence of transformations in supply on methamphetamine initiation among people injecting opioids in the United States.

BACKGROUND: Co-use of methamphetamine (MA) and opioids (pharmaceutical pills, heroin and fentanyls) has increased in the United States and is represented in rising mortality. Although coinciding with the import of low cost, high potency and purity methamphetamine, the relationship between supply and demand in propelling this polydrug use is not well understood. We consider the influence of macro changes in supply on the uptake of opioid and methamphetamine co-use by injection at the level of individual drug and injection initiation in West Virginia, a state which leads the US in drug overdose mortality. METHOD: We recruited n = 30 people for semi-structured interviews who self-reported injecting heroin/fentanyl and using methamphetamine by any route at a West Virginia syringe service program and through snowball sampling. Interviews were recorded and transcripts analyzed using a thematic approach. Ethnographic observation was also conducted and recorded in fieldnotes. Sequence of substance and mode of use initiation and use trajectories for opioids and stimulants were charted for each participant. RESULTS: A clear pattern of individual drug initiation emerged that matched each successive supply wave of the US overdose epidemic: 25 participants had initiated opioid use with pills, followed by heroin, often mixed with/replaced by fentanyl, and subsequently added methamphetamine use. For participants, the supply and consumption of opioid analgesics had set in motion a series of steps leading to the addition of stimulant injection to existing opioid injecting repertoires. Unlike other studies that have found a birth cohort effect in patterns of initiation, participants showed the same sequence across age groups. Considerations of economy, availability, dependence, tolerance and the erosion of taboos that marked transitions from opioid pills to heroin injection influenced these subsequent trajectories in novel ways. The form, timing and extent of opioid and stimulant consumption was influenced by four stages of the changing drug supply, which in turn reflected back on demand. CONCLUSION: Transformations in the social meaning and supply of methamphetamine enabled these transitions while other desired, non-injectable drugs were difficult to obtain. We discuss policy implications of injectable drugs' market dominance at this location and possible interventions.

Measuring sustainability of opioid agonist therapy programs in the context of transition from global fund support.

BACKGROUND: Programmatic and financial sustainability of health responses dependent on donor funding has risen as a major concern. In the HIV field in particular, it generated a number of instruments and assessments on sustainability and processes related to donor transition planning. The authors aimed to develop an instrument specific to opioid agonist therapy (OAT) programs as they were addressed only marginally by the HIV-specific assessments. METHODS: The development of the OAT sustainability instrument used desk review of existing HIV sustainability concepts and tools, an International Advisory Board, and piloting to validate the instrument. RESULTS: The new OAT sustainability instrument is comprised of the three parts: the conceptual framework, methodological guidelines and a practical implementation tool for assessing the degree of OAT sustainability at the country level. It measures sustainability in the three broad areas for sustainability measuring-Policy & Governance; Finance & Resources; and Services. The selection of indicators and their composites for the three sustainability areas extensively used the United Nations and World Health Organization's guidance on health system building blocks, on care and HIV and viral hepatitis prevention among people using opioids and for opioid dependence, and the definition of access to health framed by the United Nations Convent on Economic, Social and Cultural Rights. The instrument's methodological guidelines require the engagement of a national consultant to conduct desk review, key informant interviews and focus groups for measuring discrete milestones and adding qualitative information for interpretation of the data, progress and opportunities. The guidelines advise engaging a country-specific multi-stakeholder advisory group for planning, validation and follow-up of the assessment. The pilot of the instrument in 3 countries in 2020 validated it and required minor adjustments in the instrument. By mid-2023, the instrument has been successfully applied in 5 countries. CONCLUSIONS: The developed instrument enables a comprehensive review of the resilience of OAT programs and their ability to scale up and to inform a roadmap for improved sustainability. While developed in the context of Eastern Europe and Central Asia, it has been reviewed by a global advisory panel and could be easily adapted outside this regional context.

"I Heard of PrEP-I Didn't Think I Needed it." Understanding the Formation of HIV Risk Perception Among People Who Inject Drugs.

Uptake of pre-exposure prophylaxis medication (PrEP) to prevent HIV among people who inject drugs (PWID) remains extremely low in the United States. West Virginia's rising HIV incidence and highest drug overdose rate in the nation makes it an important locus for opioid use and HIV risk interaction. In this pilot study we pioneered the use of Cultural Theory among PWID to understand HIV-related risk perception arising from four contrasting modes of social organization. Carried out during an HIV outbreak, we explored PrEP uptake qualitatively as a window onto risk perception. Of the 26 interviewees, 18 were HIV- and despite the medication's free availability from the health center where recruitment took place, none had taken PrEP, half considering they were not at risk. Intimate couples who showed characteristics of 'enclaves' considered the boundary around themselves protective against HIV, creating a safe space or 'invisible risk group'. Higher HIV risk was perceived among those who were housed compared to those living homeless. Beliefs about the causation of the local HIV outbreak and the validity of scientific research corresponded with characteristics of the contrasting modes of social organization and the approach is promising for informing public health interventions among PWID.

Impact of 5 years of hepatitis C testing and treatment in the North East of England prisons.

Hepatitis C virus infection (HCV) is prevalent in prisons. Therefore, effective prison HCV services are critical for HCV elimination programmes. We aimed to evaluate the efficacy of a regional HCV prison testing and treatment programme. Between July 2017 and June 2022, data were collected prospectively on HCV test offer and uptake rates, HCV Antibody (HCV-Ab) and HCV-RNA positivity, treatment starts and outcomes for new inmates incarcerated in three prisons. Rates of HCV-Ab and RNA positivity at reception, incidence of new HCV infections and reinfection following treatment were determined. From a total of 39,652 receptions, 33,028 (83.3%) were offered HCV testing and 20,394 (61.7%) completed testing. Including all receptions, 24.5% of tests (n = 4995) were HCV-Ab positive and 8.4% of tests (n = 1713) were HCV-RNA positive. When considering the first test for each individual (median age 34 years; 88.1% male), 14.8% (n = 1869) and 7.2% (n = 905) were HCV-Ab and HCV-RNA positive, respectively. The incidence of new HCV-Ab and RNA positivity was 5.1 and 3.3 per 100 person-years, respectively. Of 1145 HCV viraemic individuals, 18 died within 6 months and 150 were rapidly transferred out of area, leaving 977 individuals with outcomes. Of these, 835 (85.5%) received antivirals and 47 spontaneously cleared the infection, leaving 95 (9.7%) untreated. 607 (72.7%) achieved SVR. 95 patients had reinfection post-treatment (rate 10.1 cases per 100 person-years). Testing for HCV has increased in our prisons and the majority with viraemia are initiated on antiviral treatment. Reassuringly, a significant fall in frequency of HCV-RNA positivity at prison reception was observed suggesting progress towards HCV elimination.

What is the impact of a Hepatitis C 'test, trace and treat' pilot using peer workers?

Chronic Hepatitis C virus (HCV) infection is a major cause of morbidity and deaths worldwide. HCV treating teams are working toward the goal of eliminating HCV by 2030. People who inject drugs (PWIDs) are at high risk of HCV but contact tracing is not routine practice. Here, we present the outcomes of a HCV 'test, trace and treat' pilot using peer workers to test contacts of individuals with HCV. PWIDs with HCV were invited to participate when they presented for treatment. For those agreeing to participate, a peer approached them to invite potential contacts for HCV testing. Data were collected on uptake, HCV test results, treatment rates and reasons for declining. Overall, 295 individuals (162 recent HCV [<1 year], 69 reinfections, 64 known chronic HCV) were invited to participate, of whom 147 (50%) agreed and 30 (20% of those agreeing) brought forward 120 contacts for testing. Of these, 44 (37%) were HCV RNA positive, including 23 who were not known to services. 34 (77%) started antiviral treatment. HCV RNA positivity was highest in contacts of reinfections (45%) compared with recent HCV (33%) and known chronic HCV (25%). The most common reason for index individuals declining participation was that they reported no longer being in contact with individuals from their injecting network (65%). In conclusion, half of PWIDs with HCV agreed to participate in the pilot, but only 20% of these brought contacts forward. The frequency of active HCV was high in the contacts and the majority started antiviral treatment.

Field Testing the "Avoid the Needle" Intervention for Persons at Risk for Transitioning to Injecting Drug Use in Tallinn, Estonia and New York City, USA.

This study aimed to field tested the "Avoid the Needle" (AtN) intervention to reduce transitions from non-injecting to injecting drug use in two different epidemiological settings. Respondent driven sampling was used to recruit current non-injecting drug users (NIDUs) in Tallinn, Estonia in 2018-19 and in New York City (NYC) in 2019-20. Both persons who had never injected and persons who had previously injected but not in the last 6 months were eligible; a structured interview was administered, a blood sample collected, and the intervention administered by trained interventionists. We recruited 19 non-injectors from Tallinn and 140 from NYC. Participants in Tallinn were younger and had begun using drugs at earlier ages than participants in NYC. The primary drugs used in Tallinn were amphetamine, fentanyl, and opioid analgesics, while in NYC they were heroin, cocaine, speedball, and fentanyl. Six-month follow-up data were obtained from 95% of participants in Tallinn. The study was interrupted by COVID-19 lockdown in NYC, but follow-up data were obtained from 59% of participants. There were minimal transitions to injecting: 1/18 in Tallinn and 0/83 in NYC. There were significant declines in the frequencies of using readily injectable drugs (fentanyl, amphetamine, heroin, cocaine) from baseline to follow-up in both sites (Cochran-Armitage tests for trend, χ2 = 21.3, p < 0.001 for New York City; and χ2 = 3.9, p = 0.048 for Tallinn). Reducing transitions into injecting is a potentially very important method for reducing HIV transmission and other harms of drug use. Further investigation and implementation of AtN type interventions is warranted.

Injection drug use and sexually transmitted infections among men who have sex with men: A retrospective cohort study at an HIV/AIDS referral hospital in Tokyo, 2013-2022.

Men who have sex with men (MSM) who use injection drugs (MSM-IDU) are at high risk of sexually transmitted infections (STIs), but the long-term incidence is unclear. We conducted a single-centre retrospective cohort study using the clinical records of non-haemophilia men with human immunodeficiency virus (HIV) who visited the Institute of Medical Science, the University of Tokyo (IMSUT) Hospital, located in Tokyo, Japan, from 2013 to 2022. We analysed 575 patients including 62 heterosexual males and 513 MSM patients, of whom 6.8% (35/513) were injection drug use (IDU). Compared to non-IDU MSM, MSM-IDU had a higher incidence of hepatitis C virus (HCV) (44.8 vs 3.5 /1,000 person-years (PY); incidence rate ratio (IRR) [95% confidence interval (95% CI)], 12.8 [5.5-29.3], p < 0.001) and syphilis (113.8 vs 53.3 /1,000 PY; IRR, 2.1 [1.4-3.1], p < 0.001). The incidence of other symptomatic STIs (amoebiasis, chlamydia, and gonorrhoea infections) was <4/1,000 PY. In multivariable Poisson regression analysis, HCV incidence was associated with MSM (IRR, 1.8 × 106 [9.9 × 105-3.4 × 106], p < 0.001), IDU (IRR, 10.1 [4.0-25.6], p < 0.001), and syphilis infection during the study period (IRR, 25.0 [1.2-518.3]/time/year, p < 0.001). Among men with HIV, the prevalence of IDU in MSM and the long-term incidence of STIs in MSM-IDU were high. IDU and sexual contact are important modes of transmission of HCV among HIV-infected MSM in Tokyo.

The impact of COVID-19 public health measures on attendance and overdose at supervised injecting facilities in Australia.

OBJECTIVES: The COVID-19 pandemic disrupted service provision of harm reduction and drug treatment services for people who inject drugs in many countries. The two supervised injecting facilities (SIFs) in Sydney and Melbourne were differentially impacted by the pandemic, requiring local procedural changes in each service. We aimed to examine the impact of pandemic responses (including restrictions on movement, known as 'lockdowns') on service use and key parameters such as client reports of drug injected and recorded overdose rates. STUDY DESIGN: Time series analysis of weekly client visits and monthly overdoses occurring at each service. METHODS: Administrative client data from the two SIFs (Sydney data from 1 January 2018 to 30 April 2022; Melbourne data from 1 July 2018 to 30 April 2022) were examined using interrupted time series analyses with lockdown dates in each state entered as interruption terms. We analysed weekly SIF visits overall and by drug type, and monthly rates of opioid overdose at each service. RESULTS: Lockdowns resulted in decreased visits to both services. The number of weekly client visits decreased during the first national lockdown for both the Sydney (trend change = -57.9; 95% CI [-109.4, -6.4]) and Melbourne SIF (near sig trend change = -54.8 [-110.8, 1.05]). Trends in visit numbers increased after lockdowns were lifted in each city; however, visits in Sydney have not returned to the numbers recorded prior to the pandemic. Visits to the Melbourne SIF related to heroin use declined at each lockdown (trend 1 = -42.7 [-81.5, -3.9]; trend 2 = -56.1 [-94.6, -17.7]; trend 3 = -33.8 [-67.4, -0.2]); heroin visits to the Sydney SIF declined during the first lockdown and remained low (trend = -55.6 [-82.8, -28.3]). Methamphetamine visits to the Sydney SIF fluctuated, surpassing heroin visits at several timepoints. Rates of monthly opioid overdoses at both services declined immediately following the start of the first lockdown (Sydney = -16.6 [-26.1, -6.8]; Melbourne = -6.4 [-8.7, -4.1]), with increasing trends recorded at the end of the final lockdown in each jurisdiction (Sydney = 2.8 [0.6, 5.0]; Melbourne = 1.3 [0.72, 3.2]). CONCLUSIONS: Public health restrictions related to the COVID-19 pandemic were associated with reduced client visits to, and overdoses in, Australian SIFs. Variations were noted in the drugs injected, likely reflecting changes in local drug markets. Shifts to other drugs during these periods were evident: methamphetamine in Sydney; co-injection of heroin and diphenhydramine in Melbourne.

Is use of opioid agonist treatment associated with broader primary healthcare use among men with recent injecting drug use histories following release from prison? A prospective cohort study.

BACKGROUND: A precipitous decline in health status among people recently released from prison is common. In Victoria, Australia, opioid agonist treatment (OAT) in the community involves frequent contact with primary care, potentially facilitating broader use of primary healthcare services. Among a cohort of men who injected drugs regularly pre-imprisonment, we estimated differences in rates of primary healthcare use and medication dispensation between people who did and did not receive OAT post-release. METHODS: Data came from the Prison and Transition Health Cohort Study. Three-month post-release follow-up interviews were linked with primary care and medication dispensation records. Generalised linear models were fit with one exposure (OAT: none/partial/complete) for 13 outcomes relating to primary healthcare use, pathology testing, and medication dispensation, adjusted for other covariates. Coefficients were reported as adjusted incidence rate ratios (AIRR). RESULTS: Analyses included 255 participants. Compared to no OAT use, both partial and complete OAT use were associated with increased rates of standard (AIRR: 3.02, 95%CI: 1.88-4.86; AIRR: 3.66, 95%CI: 2.57-5.23), extended (AIRR: 2.56, 95%CI: 1.41-4.67; AIRR: 2.55, 95%CI: 1.60-4.07) and mental health-related (AIRR: 2.71, 95%CI: 1.42-5.20; AIRR: 2.27, 95%CI: 1.33-3.87) general practitioner (GP) consultations, total medication (AIRR: 1.88, 95%CI: 1.19-2.98; AIRR: 2.40, 95%CI: 1.71-3.37), benzodiazepine (AIRR: 4.99, 95%CI: 2.81-8.85; AIRR: 8.30, 95%CI: 5.28-13.04) and gabapentinoid (AIRR: 6.78, 95%CI: 3.34-13.77; AIRR: 4.34, 95%CI: 2.37-7.94) dispensations, respectively. Partial OAT use was also associated with increased after-hours GP consultations (AIRR: 4.61, 95%CI: 2.24-9.48) and complete OAT use? with increased pathology utilisation (e.g. haematological, chemical, microbiological or immunological tissue/sample testing; AIRR: 2.30, 95%CI: 1.52-3.48). CONCLUSION: We observed higher rates of primary healthcare use and medication dispensation among people who reported partial and complete OAT use post-release. Findings suggest that access to OAT post-release may have a collateral benefit in supporting broader health service utilisation, underscoring the importance of retention in OAT after release from prison.

Adverse health outcomes among people who inject drugs who engaged in recent sex work: findings from a national survey.

OBJECTIVES: This study explores trends in sex work among people who inject drugs (PWID) by gender and the relationship between sex work and adverse health outcomes including overdose, injection-site, and blood-borne virus (BBV) infections. STUDY DESIGN: The Unlinked Anonymous Monitoring Survey of PWID is an annual cross-sectional survey that monitors BBV prevalence and behaviours, including transactional sex, among PWID recruited through specialist services in England, Wales, and Northern Ireland. METHODS: Trends in sex work among PWID (2011-2021) were described. Data were analysed to assess differences between PWID who engaged in sex work in the past year (sex workers [SWs]) and those who did not (non-SWs) by gender (Pearson Chi2 tests) (2018-2021). Associations between sex work in the past year and adverse health outcomes were investigated using logistic regression. RESULTS: Between 2011 and 2021, sex work among PWID remained stable, with 31% of women and 6.3% of men who inject, reporting having ever engaged in sex work, and 14% of women and 2.2% of men engaging in sex work in the past year. Between 2018 and 2021, SWs had greater odds of reporting symptoms of an injection-site infection (adjusted odds ratio (aOR): 1.68 [95% confidence interval {CI}: 1.31-2.16], P < 0.001) and reporting overdose (aOR: 2.21 [CI: 1.74-2.80], P < 0.001) than non-SWs had in the past year. Among men, SWs had 243% greater odds of having HIV than non-SWs (aOR: 3.43 [CI: 1.03-11.33], P = 0.043). CONCLUSIONS: Our findings highlight disproportionate vulnerability and intersection of overlapping risk factors experienced by PWID SWs and a need for tailored interventions which are inclusive and low-threshold.

Little Evidence for the Role of Disgust Sensitivity in Implicit Disgust to Images of White People Engaged in Injecting Drug Use (IDU).

Background: Previous research has shown that People Who Inject Drugs (PWID) are subject to public stigma, which affects access to, and provision and quality of, treatment and support services. Less is known about the socio-cognitive processes that support the development and maintenance of public stigma toward PWID. The present study investigated the role of disgust sensitivity in implicit disgust to injecting drug use. Methods: 126 participants took part in an online Implicit Association Task (IAT) measuring implicit disgust to pictorial stimuli of injecting drug use or medical injecting. Participants also completed The Disgust Scale Revised, Injecting Phobia Scale (Short Form), Attitudes to People Who Use Drugs (PWUD) scale and a substance use inventory. Results: Average IAT score was negative indicating significantly higher implicit disgust to injecting drug use. Hierarchical linear regression found that injecting phobia predicted implicit disgust to injecting drug use. Questionnaire measures of disgust did not predict implicit disgust. While animal reminder disgust and injecting phobia were significantly correlated with each other, animal reminder disgust did not predict implicit disgust scores. Conclusions: On the basis of our findings, stigma toward PWID may not be a result of feelings of disgust toward injecting drug use. We discuss findings in the context of the underlying cortical processes supporting implicit and explicit representations of disgust. Future research should seek to investigate neurophysiological evidence for disgust to and stigmatization of injecting drug use and the potential role of domains of disgust in this.

Legal Minors Who Inject: Differences in Socio-Demographics and Treatment Needs Compared to Adults in a Swedish National Sample of People with Injecting Drug Use.

BACKGROUND: Injection drug use among legal minors is under-researched. Although the population may be small in absolute terms, treatment needs may be greater than for those who began injecting as adults. Such knowledge may help tailor services more effectively. Previous research tends to use selective samples or focuses solely on medical indicators. The present study uses a larger sample drawn from national register data in Sweden over a 9-year period (2013-2021) to analyze differences in medical and social treatment needs between people who began injecting as legal minors and their older counterparts. METHOD: Data on first-time visitors to needle and syringe programmes (n = 8225, mean age 37.6, 26% women) were used. Historical socio-demographics and presenting treatment needs were compared between those with a debut injecting age under 18, and those who began injecting as adults. RESULTS: The prevalence of injecting before 18 years was 29%. This group had more negative social circumstances, such as leaving school early, worse health, and greater service consumption, compared to those who began injecting as adults. In particular, they had been subjected to a greater level of control measures, such as arrest and compulsory care. CONCLUSIONS: The present study shows that there are important health and social differences between those who inject prior to 18 and those who begin injecting as adults. This raises important questions for both child protection services and harm reduction approaches for legal minors who inject, who still qualify as 'children' in a legal and policy sense.

'The High Five Club': Social Relations and Perspectives on HIV-Related Stigma During an HIV Outbreak in West Virginia.

In the United States, HIV outbreaks are occurring in areas most affected by the opioid epidemic, including West Virginia (WV). Cultural Theory contends that multiple cultures co-exist within societies distinguished by their differing intensities of rules or norms of behavior ('grid') or degree of group allegiance/individual autonomy ('group'). Accordingly, we would expect that perceptions about HIV, including stigma, correspond with individuals' grid/group attributes. To explore this, we conducted qualitative interviews with people who inject drugs (PWID) recruited from a WV syringe service program. This paper focuses on our unexpected findings on stigma during a coinciding HIV outbreak. PWID living homeless identified as belonging to a 'street family'. Its members were mutually distrustful and constrained by poverty and drug dependence but despite their conflicts, reported openness between each other about HIV + status. Interviewees living with HIV perceived little enacted stigma from peers since the local outbreak. Contrasting stigmatizing attitudes were attributed to the town's mainstream society. The 'High Five' (Hi-V) Club, expressing defiance towards stigmatizing behavior outside the street family, epitomized the tensions between a desire for solidary and mutual support and a fatalistic tendency towards division and distrust. Fatalism may hinder cooperation, solidarity and HIV prevention but may explain perceived reductions in stigma.

[Unsafe practices fostering cutaneous abscesses in people who inject substances : Results from the ANRS-OUTSIDER study]. / Des pratiques à risque favorisant la survenue d'abcès cutanés chez les personnes qui injectent des substances : résultats de l'étude ANRS-OUTSIDER.

INTRODUCTION: Cutaneous abscesses are a common complication of intravenous substance use. Although these skin and soft tissue infections represent one of the main causes of emergency room visits and hospitalizations in people who inject drugs (PWID), data on their prevalence and causes are scarce. The present study was part of the larger ANRS-OUTSIDER project and aimed to study the factors associated with skin abscesses in PWID, focusing in particular on the different stages of injection. METHOD: Analyses were based on data of the 164 persons who regularly injected psychoactive substances participating in the French ANRS-OUTSIDER project. A face-to-face questionnaire collected data on sociodemographics, substance use, injection practices, and experience of skin abscesses in the previous six months. Factors associated with skin abscesses were studied using a logistic regression model. RESULTS: Of the 140 participants for whom abscess data were recorded at inclusion, 35% reported having a skin abscess in the previous six months. Factors associated with skin abscesses were: benefiting from universal health coverage (PUMA/CMU/AME) (Odd ratio (OR) = 0.28, confidence interval (CI) à 95%=0.08-0.99), finding the vein to inject by touch (OR=3.44, 95% CI=1.41-8.43) and licking the needle before injection (OR=5.16, 95% CI=1.10-24.30). CONCLUSION: Our results highlight that skin abscesses were very frequent among the complications observed in our sample of French PWID, and that certain injection practices fostered their occurrence. These data will provide stakeholders with useful information to improve prevention and harm reduction messages for PWID.

Extensive subcutaneous needle fragment retention due to injecting drug use.

Deaths in those with a history of injecting drug use commonly come to the attention of forensic pathologists, and therefore, one must have knowledge of possible findings and hazards of performing autopsies in these cases. This case demonstrates the finding of extensive retained broken needles in the subcutis of the arms and femoral region in a man with a long history of injecting drug use. While few or single broken needles are not uncommonly encountered, the multiplicity of needles in this case is noteworthy. We have demonstrated the findings both radiologically with PMCT and by conventional autopsy.

Epidemiology of HIV infection and associated behaviours among people who inject drugs in England, Wales, and Northern Ireland: Nearly 40 years on.

INTRODUCTION: People who inject drugs are at high risk of blood-borne infections. We describe the epidemiology of HIV among people who inject drugs in England, Wales, and Northern Ireland (EW&NI) since 1981. METHODS: National HIV surveillance data were used to describe trends in diagnoses (1981-2019), prevalence (1990-2019), and behaviours (1990-2019) among people who inject drugs aged ≥15 years in EW&NI. HIV care and treatment uptake were assessed among those attending in 2019. RESULTS: Over the past four decades, the prevalence of HIV among people who inject drugs in EW&NI remained low (range: 0.64%-1.81%). Overall, 4978 people who inject drugs were diagnosed with HIV (3.2% of cases). Diagnoses peaked at 234 in 1987, decreasing to 78 in 2019; the majority were among white men born in the UK/Europe (90%), though the epidemic diversified over time. Late diagnosis (CD4 <350 cells/µl) was common (2010-2019: 52% [429/832]). Of those who last attended for HIV care in 2019, 97% (1503/1550) were receiving HIV treatment and 90% (1375/1520) had a suppressed viral load (<200 copies/ml). HIV testing uptake has steadily increased among people who inject drugs (32% since 1990). However, in 2019, 18% (246/1404) of those currently injecting reported never testing. The proportion of people currently injecting reporting sharing needles/syringes decreased from 1999 to 2012, before increasing to 20% (288/1426) in 2019, with sharing of any injecting equipment at 37% (523/1429). CONCLUSION: The HIV epidemic among people who inject drugs in EW&NI has remained relatively contained compared with in other countries, most likely because of the prompt implementation of an effective national harm reduction programme. However, risk behaviours and varied access to preventive interventions among people who inject drugs indicate the potential for HIV outbreaks.

Determining the frequency and characteristics of Hepatitis C reinfections in North East England.

Hepatitis C virus infection (HCV) is common, and injecting drug use is the major risk factor for acquisition. Understanding HCV reinfection following treatment is an important consideration for HCV elimination programmes. The aim of this work was to assess the frequency and patterns of HCV reinfection in our region to develop avoidance strategies. All individuals who completed anti-HCV treatment with a known outcome in Tyne and Wear, England between January 2016 and May 2021 were included. This was a retrospective analysis of prospectively collected data. HCV reinfection was defined as positive HCV RNA after achieving sustained virological response 12 (SVR12). 788 of 840 patients (76% male; mean age 45.7 ± 11.9 years; 47% Genotype 1; 11% Cirrhosis; 20% started in prison) achieved SVR (94%). 443 patients (56%) had HCV RNA testing post-SVR after a median 0.82 (range 0.1-5.2) years. 56 reinfections (7.1% of all SVRs and 12.6% of SVRs who had post-SVR testing) were diagnosed. The median time to reinfection was 1.37 (range 0.1-4.0) years and the rate of reinfection was 10.5 /100 person years. 45 (80%) reinfections became chronic, 17 of whom were retreated and achieved SVR. 5 individuals developed a second reinfection. Younger age was the only factor independently associated with reinfection (HR 0.91 [0.88-0.94] p < .001). In conclusion, HCV reinfection is common and may slow our HCV elimination efforts. In order to address high reinfection rates, harm minimization approaches need improved, and we have implemented an 'HCV track and trace' pilot to try to reduce onwards HCV transmission.

Psychiatric well-being among men leaving prison reporting a history of injecting drug use: A longitudinal analysis.

BACKGROUND: Community reintegration from prison is typically stressful, with several health and social outcomes impacting psychiatric well-being during this time, often exacerbated among individuals with histories of drug use. Longitudinal data was used to assess change in psychiatric well-being over 2 years following release from prison among men who reported a recent history of injecting drug use. METHODS: Data for this study come from the Prison and Transition Health cohort study of 400 men recruited in prison prior to release and followed up over three time points. Psychiatric well-being was assessed using the 12-item General Health Questionnaire. We calculated change in individual General Health Questionnaire scores between interviews and identified covariates associated with General Health Questionnaire score using linear mixed-effects regression. RESULTS: Data from 690 follow-up interviews among 326 participants were included in analyses. There was considerable variation in individuals' General Health Questionnaire scores. Moving accommodation frequently and frequent illicit drug injections were associated with an increase in General Health Questionnaire score (i.e. decline in psychiatric well-being). Two or more prior adult imprisonment episodes, social supports and past month primary healthcare attendance were associated with a decrease in General Health Questionnaire score. CONCLUSION: Our findings identify health, social and structural influences on psychiatric well-being after release from prison that can inform re-entry programmes to support community reintegration.
