Abstract
In 2016, the Global Health Sector Strategy, ratified by the 69th World Health Assembly, set the ambitious goal of eliminating hepatitis C virus (HCV) and hepatitis B virus infections by 2030, emphasizing the importance of national screening programmes. Achieving this goal depends on each country's ability to identify and treat 80% of chronic hepatitis C cases, a critical threshold set by the World Health Organization. Traditionally, estimates of HCV prevalence have been based on interferon era studies that focused on high-risk subgroups rather than the general population. In addition, the incomplete data available from national registries also limited the understanding of HCV prevalence. The 2016 report from the European Centre for Disease Prevention and Control highlighted that HCV rates varied across European counties, ranging from .1% to 5.9%. However, data were only available for 13 countries, making the overall picture less clear. Additionally, the epidemiological data may have underestimated the true burden of HCV due to lack of awareness among those with chronic infection. The main objective of this review is to provide a comprehensive summary of HCV epidemiology in Europe in the current era of direct-acting antivirals (DAAs). The data included in the analysis range from the end of 2013 to December 2023 and have been categorised according to the United Nations Geoscheme. The resulting synthesis underscores the noteworthy impact of DAA treatment on the epidemiological situation.

Åhman A, Karlsson A, Berge J, Håkansson A. Mortality, morbidity, and predictors of death among amphetamine-type stimulant users - a longitudinal, nationwide register study. Addict Behav Rep 2024; 19:100553. [PMID: 38800761 PMCID: PMC11127464 DOI: 10.1016/j.abrep.2024.100553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 05/10/2024] [Accepted: 05/13/2024] [Indexed: 05/29/2024] Open
Abstract
Introduction Use of amphetamine-type stimulants (ATS) contributes substantially to the global burden of disease. Large-scale follow-up studies of morbidity and mortality in ATS users are few. This study analysed morbidity, mortality, and potential predictors of all-cause mortality in a nationwide cohort of patients with ATS use disorder. Methods Data was acquired from national Swedish registers. All Swedish residents 18 years or older, with a registered ATS use diagnosis in 2013-2014 were included (N = 5,018) and followed until December 31, 2017. Comorbid diagnoses and causes of death were assessed and potential predictors of all-cause mortality were examined through Cox regression. Results Median age at inclusion was 36.6 years (interquartile range 27.4---48.1) and 70.5 % were men. The crude mortality rate was 24.6 per 1,000 person-years. The adjusted all-cause standardized mortality ratio was 12.4 (95 % CI [11.34-13.55]). The most common cause of death was overdose (28.9 %). Multiple drug use (hazard ratio 1.39, 95 % CI [1.14-1.70], p = 0.004), anxiety (hazard ratio 1.39, 95 % CI [1.11-1.72], p = 0.014), viral hepatitis (hazard ratio 1.85, 95 % CI [1.50-2.29], p = 0.004), and liver disease (hazard ratio 2.41, 95 % CI [1.55-3.74], p = 0.004) were predictors of all-cause mortality. Conclusions Multiple drug use, anxiety disorders, viral hepatitis and liver diseases were identified as risk factors for death. Our findings call for better screening, prevention, and treatment of somatic and psychiatric comorbidity among ATS users to reduce mortality.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 128:104433. [PMID: 38703622 DOI: 10.1016/j.drugpo.2024.104433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 03/28/2024] [Accepted: 04/16/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND The World Health Organization (WHO) has set a goal to eliminate hepatitis C virus (HCV) infection by 2030, including a 90% reduction of HCV incidence. With the introduction of a needle syringe program (NSP) in Stockholm, Sweden, and unrestricted availability of direct acting antiviral (DAA) treatment, we investigate the change of prevalence and incidence of HCV infection among people who inject drugs (PWID) over time. METHODS All persons attending the Stockholm NSP 2013-2021 (n=4,138) were included. The prevalence of viremic HCV infection was investigated yearly. For incidence analysis, PWID at risk with at least one follow-up test were included. Participants were divided into naive defined as anti-HCV negative (n=791), and exposed, defined as anti-HCV positive with a negative HCV RNA (n=1,030). Risk factors for HCV infection were analyzed using parametric exponential proportional hazards regression models. RESULTS The prevalence of viremic HCV infection decreased from 62% to 30% year 2013-2021 while the prevalence of cured after treatment increased from 0 to 22%, corresponding to 42% cured after treatment out of eligible in 2021. The overall incidence rate in naive was 16.9 (95% CI 15.0-19.0) and in exposed 12.8 (95% CI 11.6-14.2) per 100 person years (PY) and was not significantly reduced years 2013-2015 to 2020-2021 in either group. Risk factors for incident HCV infection in multivariable analysis were sharing needles/syringes, younger age, custody/prison past year, and homelessness, whereas opioid agonist treatment was protective. CONCLUSION The prevalence of HCV was halved in PWID as unrestricted DAA treatment became available and NSP was established in Stockholm. However, overall incidence was not reduced. To meet the WHO incidence goal, targeting PWID with high injection risk behaviors for testing and treatment is essential, along with engagement in harm reduction services.

Abstract
People who inject drugs (PWID) are exposed to serious health risks such as lethal overdoses, addiction and infections. The patterns of drug use and the prevalence of hepatitis C virus (HCV) infection vary greatly between and even within countries. Data on drugs used for injection are important to inform PWID of risks and adapt healthcare. This study aimed to determine which substances are injected in Gothenburg, Sweden, and estimate the risk of HCV transmission. A total of 150 syringes handed in at the needle and syringe exchange program (NEP) in Gothenburg over a week in November 2021 were analysed for drug content using liquid chromatography coupled with high-resolution mass spectrometry. Using a dose-adjusted comparison, the main drug(s) injected was distinguished from the impurities in the syringes containing several drugs. HCV RNA was quantified by real-time PCR in an additional set of 150 syringes. Drugs were detected in >99% of analysed syringes, and the most common drugs were amphetamine (81%), followed by buprenorphine (8.0%), heroin (6.7%) and alprazolam (4.6%). Less common findings were testosterone (2.7%), methylphenidate (2.0%), MDMA (0.7%), trenbolone (0.7%) and zopiclone (0.7%). Eleven syringes (7.3%) contained more than one drug. HCV RNA was detected in 13% of the syringes, and one in 10 contained enough to potentially transmit an infection. This study underlines the importance of access to NEPs for PWID to reduce the risks associated with drug injection.

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. Subst Use Misuse 2023; 58:1473-1482.

Abstract
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.

Abstract
BACKGROUND The World Health Organization has set a goal to reach world elimination of hepatitis C virus (HCV) by 2030. Needle and syringe programs (NSP) for people who inject drugs (PWID) are crucial to achieve this goal. The NSP in Uppsala, Sweden, was opened in 2016 and has since 2018 provided HCV treatment for PWID. The aim of this study was to investigate HCV prevalence, risk factors and treatment uptake and outcome in NSP participants. METHODS Data from 450 PWID registered at the Uppsala NSP between 2016-11-01 and 2021-12-31 were collected from the national quality registry InfCare NSP. Data from the 101 PWID treated for HCV at the Uppsala NSP were collected through patient journal review. Descriptive and inferential analysis was performed. Ethical approval was obtained from the Ethical Review Board in Uppsala (dnr 2019/00215). RESULTS The mean age was 35 years. 75% were males (336/450), and 25% were females (114/450). The overall HCV prevalence was 48% (215/450) with a declining trend over time. Factors associated with a higher risk of HCV were older age at registration (OR 1.025, 95% CI 1.004-1.046), lower age at injection drug debut (OR 0.963, 95% CI 0.932-0.996), lower education level (OR 1.829, 95% CI 1.185-2.821) and higher number of total visits at the NSP (OR 1.005, 95% CI 1.001-1.009). The overall HCV treatment uptake was 47% (101/215), of which 77% (78/101) completed HCV treatment. The HCV treatment compliance was 88% (78/89). 99% (77/78) were cured with a sustained virologic response 12 weeks after completed treatment. The reinfection rate over the study period was 9/77 (11.7%); all were male with mean age of 36. CONCLUSIONS HCV prevalence, treatment uptake and treatment outcome have improved since the opening of the Uppsala NSP. However, further measures are needed to reach the HCV elimination goal. Outreach HCV treatment programs for PWID should be explored and evaluated in combination with further implementation of low-threshold programs.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection has increased among persons who inject drugs (PWID) in the United States with disproportionate burden in rural areas. We use the Risk Environment framework to explore potential economic, physical, social, and political determinants of hepatitis C in rural southern Illinois. METHODS Nineteen in-depth semi-structured interviews were conducted with PWID from August 2019 through February 2020 (i.e., pre-COVID-19 pandemic) and four with key informants who professionally worked with PWID. Interviews were recorded, professionally transcribed, and coded using qualitative software. We followed a grounded theory approach for coding and analyses. RESULTS We identify economic, physical, policy, and social factors that may influence HCV transmission risk and serve as barriers to HCV care. Economic instability and lack of economic opportunities, a lack of physically available HCV prevention and treatment services, structural stigma such as policies that criminalize drug use, and social stigma emerged in interviews as potential risks for transmission and barriers to care. CONCLUSION The rural risk environment framework acknowledges the importance of community and structural factors that influence HCV infection and other disease transmission and care. We find that larger structural factors produce vulnerabilities and reduce access to resources, which negatively impact hepatitis C disease outcomes.

Abstract
PURPOSE Needle syringe programs (NSP) significantly reduce risk behavior and HIV and hepatitis transmission in people who inject drugs (PWID). However, PWID are underrepresented in studies on health-related quality of life (HRQoL), representing a barrier to evaluate effects of public health and preventive measures related to injecting drug use. In this study, we investigate how well the two questionnaires EQ-5D-3L and SF-6D measure health in PWID. We also estimate HRQoL in the PWID population. METHOD Data on demographics, injection drug use, HIV, hepatitis status, and self-reported HRQoL were collected from 550 PWID enrolled in the Stockholm NSP at enrollment and at 6-, 12-, and 24-month follow-up. Self-rated HRQoL was measured as QALY, using EQ-5D-3L and the SF-6D. Item response theory (IRT) was used to evaluate which of the two instruments that measure health most accurately in this population. Regression analysis was used to estimate population-specific QALYs. RESULTS The IRT analysis showed that SF-6D was better suited to measure health in PWID. More specifically, SF-6D to a larger extent discriminated between persons regardless of their health status, while EQ-5D was more suitable to detect persons with poorer health. Self-rated HRQoL showed that average QALY was lower among PWID compared to the general Swedish population. However, a general increase in self-reported health was noted over time among participants. CONCLUSION This study increase knowledge of what instruments are most suitable to measure health among PWID. This is of great importance when evaluating effects of public health and preventive measures in the PWID population.

Abstract
BACKGROUND New technologies and therapies allow the possibility of a single-visit test and treat model for hepatitis C virus (HCV), addressing some of the barriers to care faced by people who inject drugs. METHODS The TEMPO Pilot Study was an interventional cohort study evaluating a single-visit test and treat intervention among people with recent injecting drug use at a one peer-led needle and syringe program (NSP) in Sydney, Australia between September 2019 and February 2021. This analysis evaluated awareness of HCV status and agreement of self-report with HCV RNA test results. The analysis also assessed acceptability of: modality of result delivery, modality of blood sampling, site of treatment, and duration of treatment. RESULTS Among 101 participants (median age 43; 31% female), 100 had a valid HCV RNA test result and 27% (27/100) were HCV RNA detectable. Overall, 65% (65/100) were aware of their status. Among people with a positive HCV RNA result, 48% (13/27) were aware of their status. People preferred same-day HCV test results (95%, 96/101), and preferred to receive results in person (69%, 70/101). Receiving treatment at an NSP was acceptable (100%, 101/101) and 78% (79/101) were willing to discuss their health with a peer NSP worker. CONCLUSION Half of people with current HCV infection were aware of their status. The high acceptability of simplified testing and treatment pathways delivered at NSPs indicates that this is an appropriate strategy to improve HCV awareness and treatment uptake in this population.

INTRODUCTION Leveraging interpersonal communication among social networks of people who inject drugs (PWID) may be an innovative strategy to increase awareness and access to hepatitis C (HCV) care. However, little is known about HCV communication patterns among PWID and if these patterns vary by gender. METHODS Egocentric network data collected at baseline from HCV-infected PWID enrolled in a randomized HCV treatment intervention trial in Baltimore, Maryland were analyzed. Logistic generalized estimating models were conducted to identify predictors of HCV communication. RESULTS Among 227 PWID, the mean age was 43.8 (SD=10.3), 28.2% (n = 64) were women and 71.8% (n = 163) were men. Female participants reported 516 dyadic relationships and male participants 1139 dyadic relationships. While there were significant gender differences based on socio-demographics, risk behavior and network composition, there were few differences in HCV communication patterns. Both men and women had increased odds of HCV communication with alters who are currently enrolled in drug treatment (AOR 1.7, 95% CI: 1.3-2.4), alters with whom participants share drug preparation equipment (AOR 3.0, 95% CI: 1.9-4.6), alters who are sex partners compared to kin (AOR 3.0; 95% CI: 1.9-4.9) and alters with whom respondents have increased trust (AOR 1.1; 95% CI: 1.11.2) and daily/weekly interactions (AOR 1.7; 95% CI 1.3-2.1). CONCLUSION PWID engaged with trusted alters about HCV disclosure and information, highlighting the important role network interventions could play in this vulnerable population.

Abstract
INTRODUCTION The effectiveness of the hepatitis C virus (HCV) treatment seems to be lower in people who inject drugs (PWID). We analyze the influence of various factors as psychiatric disorders and opioid substitution therapy (OST) on the treatment with direct-acting antivirals (DAA) in this collective. PATIENTS AND METHODS Three hundred thirty-two PWID patients were treated with DAA in 12 Spanish hospitals between 2004 and 2020. They were catalogued in recent and former consumers (if the last consumption was in the last 3 years) and several variables were included, evaluating the effectiveness of the treatment according to the viral load 12 weeks after the end of the treatment with the parameter «sustained viral response» (SVR12). RESULTS 23.4% were recent consumers and 27.7% were on OST. The 41.5% had any diagnosis of psychiatric disorder. SVR12 was 84.04%, ascending to 96.21% when excluded from the analyses the patients lost to follow-up (12.7%). SVR12 was lower due to an increase in the loss to follow-up in recent consumers and other factors like OST, being in prison the last 5 years, naïve patients, generalized anxiety disorder and benzodiazepine consumption. CONCLUSIONS The effectiveness of the HCV treatment with DAA in PWID is similar than in general population in patients whit an appropriate follow-up. It is important to maintain a closer follow-up in patients on OST, recent consumers and those with psychiatric disorders.

Abstract
Aims To investigate liver-related and all-cause mortality among amphetamine users with hepatitis C virus (HCV) infection and compare this with opioid users with HCV infection and the uninfected general population. Methods In this national register study of mortality in persons notified with HCV infection 1990–2015 and a substance-related diagnosis in Sweden, amphetamine users (n = 6,509) were compared with opioid users (n = 5,739) and a matched comparison group without HCV infection/substance use (n = 152,086). Results Amphetamine users were observed for 91,000 years and 30.1% deceased. Crude liver-related mortality was 1.8 times higher in amphetamine users than opioid users (crude mortality rate ratio 1.78, 95% CI 1.45–2.19), but there was no significant difference when adjusting for age and other defined risk factors. An alcohol-related diagnosis was associated with liver-related death and was more common among amphetamine users. Crude and adjusted liver-related mortality was 39.4 and 5.8 times higher, respectively, compared with the uninfected group. All-cause mortality was lower than in opioid users (adjusted mortality rate ratio 0.78, 95% CI 0.73–0.84), but high compared with the uninfected group. External causes of death dominated in younger ages whereas liver-related death was more common among older individuals. Conclusions This national register study presents a higher crude risk of liver-related death among HCV-infected amphetamine users compared with opioid users or the uninfected general population. The higher risk of liver-related death compared with opioid users may be explained by lower competing death risk and higher alcohol consumption. Treatment of HCV infection and alcohol use disorders are needed to reduce the high liver-related mortality.

Health literacy and changes in pattern of drug use among participants at the Stockholm Needle Exchange Program during the COVID-19 pandemic. Harm Reduct J 2021; 18:52. [PMID: 33971892 PMCID: PMC8107802 DOI: 10.1186/s12954-021-00499-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2021] [Accepted: 04/29/2021] [Indexed: 02/06/2023] Open
Abstract
Background and aims People who inject drugs may be particularly vulnerable to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) due to underlying health problems, stigma and social vulnerabilities. Harm reduction services, including needle exchange programs (NEP), have been subjected to varying degrees of disruption in the world, especially in the beginning of the coronavirus disease 2019 (COVID-19) pandemic. Compared to responses in other countries, Sweden’s initial strategy toward limiting the spread and impact of COVID-19 was less restrictive to its citizens with no imposed general societal lockdown. In this study, we investigate changes in drug use patterns, utilization of NEP associated health services, COVID-19 health literacy and the prevalence of SARS-CoV-2 antibodies among NEP clients in Stockholm during the COVID-19 pandemic.
Methods NEP visits and services provided (needles/syringes, HIV and hepatitis C tests and treatment, naloxone distributed) and overall mortality among NEP clients between January 1 and October 31, 2020, were used for trend analyses in comparison with corresponding 2019 data. Between July 27 and October 2, 2020, NEP clients (n = 232) responded to a 27 item COVID-19 Health Literacy Questionnaire. SARS CoV-2 IgG antibody tests (n = 779) were performed between June 15 and October 31, 2020. Results During the COVID-19 pandemic number of clients, client visits, naloxone distribution and HCV tests remained stable compared to 2019, while distribution of needles/syringes increased (p < 0.0001); number of HIV tests and HCV treatments decreased (p < 0.05); and mortality decreased (< 0.01). Overall, the level of health literacy concerning transmission routes and protective measures was high. SARS-CoV-2 antibody prevalence was 5.4% (95% CI 4.0–7.2). Conclusions The Stockholm NEP managed to maintain a high level of clients and services during the pandemic. In general, COVID-19 health literacy was adequate and the overall SARS-CoV-2 antibody prevalence was low compared to the general population, which highlights a need for prioritized and targeted COVID-19 vaccination among PWID.

Concordance between self-reported and current hepatitis C virus infection status in a sample of people who inject drugs in Sydney and Canberra, Australia. Drug Alcohol Rev 2021; 40:1349-1353. [PMID: 33759276 DOI: 10.1111/dar.13282] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 02/10/2021] [Accepted: 02/28/2021] [Indexed: 01/07/2023]
Abstract
INTRODUCTION Awareness of hepatitis C virus (HCV) status among people who inject drugs is critical to ensure linkage to care and reduce transmission risk. Testing pathways, confusion about results and possible reinfection raise potential for discordance between perceived and actual HCV status among people who inject drugs. We evaluated self-reported and serologically confirmed HCV status concordance among a sample of Australian people who inject drugs. METHODS Data were collected in May-June 2018 from participants in Canberra and Sydney, Australia, who had injected drugs at least monthly in the past 6 months. Participants completed a structured interview assessing self-reported HCV status and provided a dried blood spot sample for HCV RNA testing. RESULTS Of 103 participants, 95% self-reported ever receiving antibody testing, 58% of whom reported having received RNA testing. Seventy-three percent of participants reported never having been told that they had HCV, 18% reported current infection and 9% did not know their current status. According to dried blood spot RNA testing, 20% were currently infected. Over a quarter of the sample (28%, n = 29) did not accurately report their HCV status, half of whom were unaware of a current infection. DISCUSSION AND CONCLUSIONS With over one-quarter of the sample in our study not accurately reporting their current HCV status, our findings reinforce the importance of regular testing for active infection, and the need for improved health literacy on HCV antibody and RNA test results, HCV status post-treatment and reinfection risk.

Abstract
BACKGROUND Hepatitis C is highly prevalent among people who use drugs (PWUD), and the hepatitis C virus (HCV) epidemic is less characterised in Norway. The aims of the study were to assess the prevalence and treatment willingness in high-risk populations by reaching out to frequently visited sites for high-risk populations. METHODS Individuals from high-risk populations were included from September 2015 to March 2017. Two dedicated study nurses frequently visited the local opioid substitution clinic, outpatient clinics, PWUD day centres, local prison, and refugee centre in Trondheim, Norway. Demographic data, risk behaviour, and clinical symptoms were obtained by study questionnaire. Subjects with anti-HCV+ rapid test were subsequently tested for HCV RNA and genotyped. Viraemic patients were offered referral for HCV treatment evaluation. RESULTS A total of 381 participants were included in the study: 52 immigrants, 62 prisoners, and 267 PWUD. The anti-HCV prevalence rates were 0% (n = 0) in immigrants, 40% (n = 25) in prisoners, and 61% (n = 164) in PWUD, with 24% (n = 15) of prisoners and 42% (n = 108) of PWUD being viraemic. Of those qualifying for treatment (n = 31), 30 wished to be evaluated. CONCLUSION This study showed high HCV prevalence in prisoners and PWUD and that infected high-risk patients were interested in treatment evaluation.

A prospective cohort study of risk behaviours, retention and loss to follow-up over 5 years among women and men in a needle exchange program in Stockholm, Sweden. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 90:103059. [PMID: 33360734 DOI: 10.1016/j.drugpo.2020.103059] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Revised: 11/09/2020] [Accepted: 11/18/2020] [Indexed: 01/05/2023]
Abstract
BACKGROUND Needle exchange programs (NEP) are important in reducing risk behaviours among people who inject drugs (PWID), also exposed to HIV and hepatitis C (HCV) through injecting drug use (IDU). Women (WWID) compared to men who inject drugs (MWID), are particularly vulnerable with complex needs, however less is known about their risk determinants and NEP outcomes. METHODS In an open prospective NEP cohort, 697 WWID and 2122 MWID were followed, 2013-2018. Self-reported socio/drug-related determinants for receptive injection (needle/syringe and paraphernalia) and sexual risk behaviours at enrolment, lost to follow-up (LTFU) and probability of retention, were assessed for both groups. Multivariable logistic regression (adjusted odds ratios, aOR) for enrolment and Poisson regression (adjusted incidence rate ratios, aIRR) for LTFU, were used. Cumulative NEP-retention probability was analysed using a six- and 12-month scenario. RESULTS At NEP enrolment, injection risk behaviours among WWID were associated with: younger age; homelessness; amphetamine-IDU; non-participation in opioid substitution therapy (OST); history of custody and among MWID: lower education level; cohabitation; homelessness, being a tenant; amphetamine-IDU; non-participation in OST; history of being sectioned, HIV-negative and HCV-positive. Condomless sex among WWID was associated with: younger age; lower education-level; cohabitation; having a partner; amphetamine-IDU; non-participation in OST; being HIV-negative and HCV-positive and among MWID: younger age; married; cohabitation; having a partner; amphetamine-IDU; non-participation in OST; history of custody, prison and being HIV-negative. WWID had higher NEP-retention levels compared to MWID over time. Being LTFU among WWID was associated with being HIV-negative and reporting injection risk behaviours and among MWID, younger age, non-participation in OST, being HIV-negative and having protected sex. CONCLUSIONS Despite better NEP compliance among WWID, high injection and sexual risk behaviours in both gender-subgroups, especially in intimate relationships, suggests ongoing HCV and HIV-infection risks. Subgroup-variation in the NEP continuum of care warrants more gender-disaggregated research and tailoring gender-sensitive services may improve prevention, health and retention outcomes.

Abstract
BACKGROUND Women who inject drugs (WWID) show higher levels of injecting risk behaviour compared to men, putting them at risk of contracting HIV and hepatitis C (HCV). Compared to men, WWID are also less present in harm reduction programs such as needle exchange programs (NEP). The aim of this study is to investigate reasons for, and barriers to, participation in NEP among WWID in Sweden, and to identify measures that could be taken to strengthen the program and increase participation among WWID. METHOD In-depth interviews (IDIs) were conducted with 20 WWID who had participated in the Stockholm NEP for at least six months and was over 18 years old. IDIs were audio recorded and transcribed et verbatim. Qualitative content analysis was used to identify themes. RESULTS The need for sterile injection equipment was identified as the main driver to join and remain in the NEP program. Continuous participation in the NEP was further driven by easy access to a multitude of health-related services. The most valued service was the sexual and reproductive health services (SRHR), allowing participants to access contraceptives, cervical cancer screening and sexually transmitted infections testing (STI-testing). NEP staffs' respectful treatment of participants further contributed to program participation. However, participants also expressed a number of concerns around NEP participation, which created barriers to joining. These included losing custody or visitation rights to children, male partner jealousy and violence, unwillingness to spend time in the waiting area and fear of receiving positive HIV/HCV test results. Practical barriers included limited opening hours and travel distance to the NEP. To strengthen the program, most participants requested additional SRHR services. Most participants also proposed some form of "women only" access to the NEP, to strengthen the feeling of the NEP as a safe space. CONCLUSION This study identified factors that may increase uptake of NEP among WWID. Additional SRHR services and "women only" access are recommended to be implemented and evaluated as part of NEP. These findings may inform and improve the current scale-up of NEPs in Sweden to ensure equal access to services.

Abstract
Background Treatment with direct-acting antiviral agents (DAAs) offers an opportunity to eliminate hepatitis C virus (HCV) endemic among people who inject drugs (PWID) and people enrolled in opioid agonist therapy (OAT) programs. The objective of this study was to estimate and to compare HCV treatment uptake after the introduction of DAAs among patients receiving OAT in Sweden and Norway. We also aimed to evaluate predictors of DAAs treatment among OAT patients in both countries. Methods This observational study was conducted with data from The Swedish Prescribed Drug Register and The Norwegian Prescription Database. We studied dispensed medications to calculate HCV treatment among OAT patients from 2014 to 2017 in Sweden and Norway. HCV prevalence was estimated from primary and secondary sources. Dispensations of medicines from different therapeutic areas, which served as proxy for co-morbidities in 2017, were conditionally adjusted for age, gender, and OAT medications. Logistic regression was used to evaluate these parameters. Results In total 3529 individuals were identified with dispensed OAT in the Swedish cohort and 7739 individuals in the Norwegian cohort. HCV treatment was utilized by 407 persons in Sweden and 920 in Norway during the study period. Annual HCV and DAA treatment uptake increased in both countries. The estimated cumulative HCV treatment uptake at the end of 2017 was 31% in Norway and 28% in Sweden. DAA treatment was associated with increased age (aOR 1.8; 95% CI 1.0–3.2) and the dispensation of drugs used for diabetes (aOR 3.2; 95% CI 1.8–5.7) in Sweden. In Norway, lipid modifying agents and antibacterials were associated with decreased odds (aOR 0.4; 95%CI 0.2–0.9, aOR 0.8; 95%CI 0.6–1.0). Conclusions An increase in DAA treatment and HCV treatment uptake was observed among Swedish and Norwegian OAT patients whilst introducing new direct-acting antiviral treatment regimens. However, more than two thirds of the OAT population in Norway and Sweden were untreated at the beginning of 2018. A further scale-up is crucial in order to control and eliminate the HCV endemic among OAT patients.

Systematic Review and Meta-Analysis of Global Prevalence of HBsAg and HIV and HCV Antibodies among People Who Inject Drugs and Female Sex Workers. Pathogens 2020; 9:pathogens9060432. [PMID: 32486342 PMCID: PMC7350380 DOI: 10.3390/pathogens9060432] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2020] [Revised: 05/01/2020] [Accepted: 05/29/2020] [Indexed: 02/06/2023] Open
Abstract
The main objective of this study was to evaluate the prevalence of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), hepatitis C virus (HCV) and hepatitis B virus (HBV) and their co-infections among people who inject drugs (PWID) and female sex workers (FSWs). Data sources were searched from January 2008 to October 2018 in different databases. Data were analyzed in Stata 16 software using the Metaprop command. The results showed that the prevalence of HIV, HCV and HBV among PWID was 15%, 60% and 6%, respectively. The prevalence of HIV, HCV and HBV among FSWs was 5%, 1% and 3%, respectively. The prevalence of HIV/HCV, HIV/HBV, HCV/HBV and HIV/HCV/HBV co-infections among PWID was 13%, 2%, 3% and 2%, respectively. The prevalence of HIV/HCV and HIV/HBV co-infections among FSWs was 3% and 1%, respectively. The results show that the prevalence of HCV and HIV infections in PWID and the prevalence of HIV in FSWs is higher than their prevalence in the general population. Interventions for the prevention of HIV and HCV in PWID appear to be poor, and may not be sufficient to effectively prevent HIV and HCV transmission.

Abstract
Aims: Hepatitis C virus (HCV) is a slowly progressive disease, often transmitted among people who inject drugs (PWID). Mortality in PWID is high, with an overrepresentation of drug-related causes. This study investigated the risk of death in patients with chronic hepatitis C virus (HCV) infection with or without illicit substance use disorder (ISUD).Methods: Patients with HCV were identified using the Swedish National Patient Registry according to the International Classification of Diseases-10 (ICD-10) code B18.2, with ≤5 matched comparators from the general population. Patients with ≥2 physician visits with ICD-10 codes F11, F12, F14, F15, F16, or F19 were considered to have ISUD. The underlying cause of death was analyzed for alcoholic liver disease, non-alcoholic liver disease, liver cancer, drug-related and external causes, non-liver cancers, or other causes. Mortality risks were assessed using the standardized mortality ratio (SMR) with 95% CIs and Cox regression analyses for cause-specific hazard ratios.Results: In total, 38,186 patients with HCV were included, with 31% meeting the ISUD definition. Non-alcoholic liver disease SMRs in patients with and without ISUD were 123.2 (95% CI, 103.7-145.2) and 69.4 (95% CI, 63.8-75.3), respectively. The significant independent factors associated with non-alcoholic liver disease mortality were older age, being unmarried, male sex, and having ISUD.Conclusions: The relative risks for non-alcoholic liver disease mortality were elevated for patients with ISUD. Having ISUD was a significant independent factor for non-alcoholic liver disease. Thus, patients with HCV with ISUD should be given HCV treatment to reduce the risk for liver disease.

Abstract
Background and aims: Sharing of unsterile injection equipment contributes to transmission of hepatitis C virus (HCV), HIV and hepatitis B virus (HBV) among people who inject drugs (PWID) but is largely preventable through needle exchange programmes (NEP). Sweden has been one of the last countries in Europe to scale up access to NEP for PWID, who consequently have high prevalence rates of HCV and HIV. The aim of the study was to investigate demographic and drug-related determinants of injection risk behaviours, sharing of needle/syringe and paraphernalia, and patterns of change over time in subgroups of PWID participating in the Stockholm NEP.Methods: The Stockholm NEP started in 2013 as the first formal NEP in the region. A total of 2860 PWID were included in this prospective open cohort study. The association between demographic and drug-related determinants and injection risk behaviours were analysed at baseline and followed up at 6, 12, 24, 36 and 48 months post-enrolment.Results: The following factors were associated with high levels of injection risk behaviours at inclusion: female gender, homelessness, low education level, younger age, amphetamine use, not in opioid substitution therapy (OST), being HIV negative and being HCV positive. We found an overall significant decrease in injection risk behaviours over time among participants. Not previously investigated in depth, we found that subgroups of participants varied in degrees of injection risk behaviour reduction over time and that women decreased injection risk behaviours faster than men. Enrolment in OST, HIV positive and age <25 years at inclusion were not associated with a decrease in injection risk behaviours over time.Conclusions: In this prospective cohort study over 4 years, we found that NEP participation was associated with a significant decrease in injection risk behaviours.

Abstract
To reach the WHO goal of hepatitis C elimination, it is essential to identify the number of people unaware of their hepatitis C virus (HCV) infection and to investigate the effect of interventions on the disease transmission dynamics. In many high-income countries, one of the primary routes of HCV transmission is via contaminated needles shared by people who inject drugs (PWIDs). However, substantial underreporting combined with high uncertainty regarding the size of this difficult to reach population, makes it challenging to estimate the core indicators recommended by the WHO. To support progress toward the elimination goal, we present a novel multi-layered dynamic transmission model for HCV transmission within a PWID population. The model explicitly accounts for disease stage (acute and chronic), injection drug use status (active and former PWIDs), status of diagnosis (diagnosed and undiagnosed) and country of disease acquisition (domestic or abroad). First, based on this model, and using routine surveillance data, we estimate the number of undiagnosed PWIDs, the true incidence, the average time until diagnosis, the reproduction numbers and associated uncertainties. Second, we examine the impact of two interventions on disease dynamics: (1) direct-acting antiviral drug treatment, and (2) needle exchange programs. As a proof of concept, we illustrate our results for a specific data set. In addition, we develop a web application to allow our model to be explored interactively and with different parameter values.

Prevalence of Viremic hepatitis C, hepatitis B, and HIV infection, and vaccination status among prisoners in Stockholm County. BMC Infect Dis 2019; 19:955. [PMID: 31706284 PMCID: PMC6842501 DOI: 10.1186/s12879-019-4581-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 10/21/2019] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND Identification and knowledge of settings with high prevalence of hepatitis C virus (HCV) infection is important when aiming for elimination of HCV. The primary aim of this study was to estimate the prevalence of viremic HCV infection among Swedish prisoners. Secondary aims were to estimate the prevalence of hepatitis B surface antigen (HBsAg), human immunodeficiency virus (HIV), and the proportion who have received hepatitis B virus (HBV) vaccination. METHODS A cross-sectional study of all incarcerated persons (n = 667) at all prisons (n = 9) in Stockholm County was conducted. All prisoners are routinely offered opt-in screening for HCV antibodies (anti-HCV), HCV RNA, HBsAg, anti-HBs, anti-HBc and HIV Ag/Ab at prison in Sweden. Data on the results of these tests and the number of received HBV vaccine doses were collected from the prison medical records. The parameters of HCV RNA, anti-HCV, and occurrence of testing for HCV were analysed in multiple logistic regression models in relation to age, sex and prison security class. RESULTS The median age was 35 (IQR 26-44) years, and 93.4% were men. Seventy-one percent (n = 471) had been tested for anti-HCV, 70% (n = 465) for HBsAg and 71% (n = 471) for HIV. The prevalence of anti-HCV, HCV RNA, HBsAg and HIV Ag/Ab was 17.0, 11.5, 1.9, and 0.2%, respectively among tested persons. The proportion of prisoners who had received full HBV vaccination was 40.6% (n = 271) among all study subjects. CONCLUSIONS The prevalence of viremic HCV infection among Swedish prisoners in Stockholm County was 11.5%, which is high in comparison to the general population. Therefore, when aiming for the WHO goal of HCV elimination, prisons could suit as a platform for identification and treatment of HCV infection. There is a need to increase testing for blood-borne viruses and to improve vaccination coverage against HBV in Swedish prisons.

Utility of a one-step screening and diagnosis strategy for viremic HCV infection among people who inject drugs in Catalonia. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2019; 74:236-245. [PMID: 31706159 DOI: 10.1016/j.drugpo.2019.10.012] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 10/21/2019] [Accepted: 10/21/2019] [Indexed: 12/23/2022]
Abstract
BACKGROUND In Catalonia (Spain), people who inject drugs (PWID) face numerous barriers to access to mainstream healthcare services for hepatitis C confirmatory diagnosis and treatment, so simplified testing strategies for viremic infection are urgently needed. Among PWID attending harm-reduction services in Catalonia, we aimed (i) to assess the utility of an in-house HCV-RNA detection assay on dried blood spots (DBS) as a one-step screening and confirmatory diagnosis strategy for hepatitis C, (ii) to estimate the prevalence of viremic HCV infection, and (iii) to identify factors associated with unawareness of viremic infection. METHODS A cross-sectional study of current PWID (N = 410) was performed in four harm-reduction services. All participants underwent HCV antibody point-of-care testing and parallel DBS collection for centralized RNA testing. An epidemiological questionnaire was administered. Paired EDTA-plasma samples were additionally collected for HCV viral load testing in 300 participants. RESULTS HCV-RNA testing from DBS was feasible and showed 97.2% sensitivity and 100% specificity for viral loads >3000 IU/mL in real-life conditions. No significant differences in the performance when detecting viremic infections were observed between this one-step testing strategy vs. the conventional two-step algorithm involving venepuncture. Overall HCV seroprevalence was 79.8%, and prevalence of viremic infection was 58.5%. Importantly, 35.8% of viremic HCV participants were unaware of their status, and no specific socio-demographic or bio-behavioral factors independently associated with unawareness of viremic infection were identified. Among participants reporting a past or current HCV infection, 29.0% stated having received HCV antiviral treatment. CONCLUSION The high viremic HCV infection burden among PWID attending HRS, estimated for the first time in Catalonia, together with the low levels of awareness of viremic status and access to treatment, suggest that scaling up this one-step screening and diagnosis strategy to the network of harm-reduction services would help to achieve HCV elimination targets set by the World Health Organization.

Abstract
Background Although significant improvement in efficacy measured by a sustained virological response, the high acquisition costs of direct-acting antivirals limit the access for patients and influence the costs of healthcare resource utilisation in hepatitis C. It is important to have the latest estimates of prevalence, especially in high-risk groups, for cost of illness, cost-effectiveness and budget impact studies. Methods Original studies on the estimates of the prevalence among general and high-risk groups in the European Union/European Economic Area (EU/EEA) were retrieved from Medline and Embase for the period from 2015 to 2018. All included studies were evaluated for risk of selection bias and summarised together in a narrative form. Results from previous reviews and updated searches were compared per country among different populations, respectively. Results Among the 3871 studies identified, 46 studies were included: 20 studies were used for the estimate of the general population; 3 for men who have sex with men (MSM); 6 for prisoners; and 17 for people who inject drugs (PWID). Compared with the results reported in previous systematic reviews, the updated estimates were lower than previously in most available countries. Anti-HCV general population prevalence estimates ranged from 0.54 to 1.50% by country. The highest prevalence of anti-HCV was found among PWID (range of 7.90–82.00%), followed by prisoners (7.00–41.00%), HIV-positive MSM (1.80–7.10%), HIV-negative MSM (0.20–1.80%), pregnant women (0.10–1.32%) and first-time blood donors (0.03–0.09%). Conclusions Our study highlights the heterogeneity in anti-HCV prevalence across different population groups in EU/EEA. The prevalence also varies widely between European countries. There are many countries that are not represented in our results, highlighting the need for the development of robust epidemiological studies.

Abstract
Hepatitis C has a relevant global impact in terms of morbidity, mortality and economic costs, with more than 70 million people infected worldwide. In the resolution, "Transforming our world: the 2030 Agenda for Sustainable Development" was included as a focus area in the health-related goal with world leaders pledging to "combat" it by 2030. In response, WHO drafted the Global Viral Hepatitis Strategy carrying the ambitious targets to reduce the number of deaths by two-thirds and to increase treatment rates up to 80%. Despite the availability of highly effective therapeutic regimens based on direct-acting antivirals many barriers to HCV eradication still remain. They are related to awareness of the infection, linkage to care, availability of the therapeutic drug regimens and reinfection. Overall, if an effective prophylactic vaccine will not be available, HCV eradication appears difficult to achieve in the future.

Abstract
Background and aims: Sharing of unsterile injection equipment among people who inject drugs (PWID) is the major transmission-route for hepatitis C (HCV). HCV is highly prevalent in PWID in the Stockholm needle exchange programme (NEP). The frequency of advanced liver fibrosis among the participants is, however, unknown. Methods: From December 2016 to April 2018, all participants with chronic hepatitis C infection (CHC) were offered liver fibrosis evaluation at the Stockholm NEP, including liver stiffness measurement (LSM), a medical history and expanded blood tests to evaluate APRI and FIB-4 scores. Results: A total of 2037 individuals were enrolled of whom 964 (47.3%) had CHC. LSM was performed in 203 (21.1%) of eligible participants of whom 85% had mild fibrosis (LSM ≤9.4 kPa) and 15% advanced fibrosis (LSM ≥9.5 kPa). APRI >1 and FIB-4 > 3.25 only identified 30% of participants with advanced fibrosis. However, all 31(100%) participants with advanced fibrosis were detected when APRI >1 was combined with an age of ≥40 years and an injection drug use (IDU) duration of ≥15 years. Conclusions: We found that the diagnostic work-up for advanced fibrosis can be simplified with this combination of easily available factors. This allows identification of PWID in need of immediate HCV treatment to prevent further disease progression. Furthermore, LSM can be avoided among PWID with mild fibrosis, identified by age <40 years combined with IDU duration of <15 years and APRI score <1. This strategy enhances the HCV care cascade where LSM is not easily available, and will thus facilitate HCV treatment initiation.

Abstract
The major transmission route for hepatitis C virus (HCV) is through sharing of unsterile injection equipment among people who inject drugs (PWID). The WHO strategy for HCV elimination by 2030 proposes increased efforts to treat PWID populations that drive the HCV epidemic. Among participants in the Stockholm needle exchange programme (NEP), the HCV prevalence is 60%. We aimed to study HCV incidence, spontaneous HCV clearance rate, and predictors associated with new HCV infections and reinfections in NEP participants. All 2320 patients enrolled in the programme between 8 April 2013 and 23 September 2016 were tested for HCV at baseline, and responded to a questionnaire regarding sociodemographic data and injection risk behaviour. Tests for HCV were repeated at an interval of 3-6 months. The anti-HCV prevalence in the NEP participants at baseline was 77%, and the prevalence of HCV RNA was 57%. 24% of the anti-HCV positive were HCV RNA negative with a spontaneously cleared HCV infection. The overall HCV incidence rate was 22/100 PY. The HCV incidence rate in the HCV naive group was 26/100 PY, and in the spontaneously cleared group 19/100. Although there were no significant differences in becoming HCV infected between the two groups (31% vs 29%), the rate of spontaneous HCV clearance was significantly lower in the HCV naive group, 20% vs 44%, (P < 0.05). A high HCV incidence rate was noted among the PWID indicating that treatment needs to be scaled up in conjunction with harm reduction measures to achieve HCV elimination goals set by WHO. This includes high coverage needle exchange programmes and effective addiction treatment for substance users, including opiate substitution treatment.
