Human rights and access to hepatitis C treatment for people who inject drugs

The experiences of people who use injection drugs with accessing hepatitis c testing and diagnosis in western countries: A scoping review

BACKGROUND

The purpose of this scoping review was to summarize the literature that reported on the experiences of people who use injection drugs' access to hepatitis C testing and diagnosis in Western countries.

METHODS

The initial search was conducted in 2020 and an updated review was completed in 2022. Seven electronic databases were searched using a peer-reviewed search strategy and included: full-text, peer-reviewed studies with people who inject(ed) drugs, hepatitis C testing or diagnosis, conducted in Western countries. Excluded were studies published prior to 2014 and intervention studies. Two-step screening was conducted in duplicate. Conventional content analysis was used.

RESULTS

Six studies were found from the search. The studies were published between 2014 and 2021 in Australia, United Kingdom, and United States. A total of 19 participant characteristics were extracted to contextualize their experiences, demonstrating a lack of demographic data. Four themes were found: Awareness and Knowledge, Stigma, Healthcare Service, and Psychological Responses. There were 58 occurrences of client quotes where participants described their experiences, 29 occurrences of quotes describing client-identified barriers, and 14 occurrences of quotes describing client-identified facilitators.

CONCLUSION

A scoping review was conducted to present the experiences, barriers, and facilitators of people who use injection drugs to hepatitis C testing. The lack of demographic data and connection to client quotes further exacerbates the inequities among the population by overlooking their intragroup identities. Understanding their experiences of accessing hepatitis C testing and collecting demographic data will help advance health policies and interventions targeting people who use injection drugs.

The effect of different types of migration on symptoms of anxiety or depression and experience of violence among people who use or inject drugs in Kachin State, Myanmar

BACKGROUND

Evidence on the social determinants of mental health conditions and violence among people who inject or use drugs (PWUD) is limited, particularly in conflict-affected countries. We estimated the prevalence of symptoms of anxiety or depression and experience of emotional or physical violence among PWUD in Kachin State in Myanmar and examined their association with structural determinants, focusing on types of past migration (migration for any reason, economic or forced displacement).

MATERIALS

A cross-sectional survey was conducted among PWUD attending a harm reduction centre between July and November 2021 in Kachin State, Myanmar. We used logistic regression models to measure associations between past migration, economic migration and forced displacement on two outcomes (1) symptoms of anxiety or depression (Patient Health Questionnaire-4) and (2) physical or emotional violence (last 12 months), adjusted for key confounders.

RESULTS

A total of 406, predominantly male (96.8%), PWUD were recruited. The median age (IQR) was 30 (25, 37) years, most injected drugs (81.5%) and more commonly opioid substances such as heroin or opium (85%). Symptoms of anxiety or depression (PHQ4 ≥ 6) were high (32.8%) as was physical or emotional violence in the last 12 months (61.8%). Almost one-third (28.3%) had not lived in Waingmaw for their whole life (migration for any reason), 77.9% had left home for work at some point (economic migration) and 19.5% had been forced to leave home due to war or armed conflict (forced displacement). A third were in unstable housing in the last 3 months (30.1%) and reported going hungry in the last 12 months (27.7%). Only forced displacement was associated with symptoms of anxiety or depression [adjusted odds ratio, aOR 2.33 (95% confidence interval, CI 1.32-4.11)] and recent experience of violence [aOR 2.18 (95% CI 1.15-4.15)].

CONCLUSION

Findings highlight the importance of mental health services integrated into existing harm reduction services to address high levels of anxiety or depression among PWUD, particularly among those who have been displaced through armed conflict or war. Findings reinforce the need to address broader social determinants, in the form of food poverty, unstable housing and stigma, in order to reduce mental health and violence.

Randomized clinical trial: Direct-acting antivirals as treatment for hepatitis C in people who inject drugs: Delivered in needle and syringe programs via directly observed therapy versus fortnightly collection

Hepatitis C virus (HCV) treatment in people who inject drugs (PWID) is delivered within settings frequented by PWID, such as needle and syringe programs (NSP). The optimal direct-acting antiviral (DAA) dispensing regimen among NSP clients is unknown. This study compared cures (Sustained virologic response 12 weeks post-treatment, [SVR₁₂ ]) across three dispensing schedules to establish non-inferiority of fortnightly dispensing versus directly observed therapy. The ADVANCE HCV study was a randomized, unblinded trial, recruiting PWID attending NSP in Tayside, Scotland, between January 2018 and November 2019. HCV-positive participants were randomized to receive DAAs via directly observed therapy, fortnightly provision or fortnightly provision with psychological intervention. A modified intention to treat analysis was used to identify differences in cures between the three treatment regimes. The study was registered with clinicaltrials.gov; NCT03236506. A total of 110 participants completed the study. 33 participants received directly observed therapy, with 90.91% SVR₁₂ ; 37 received fortnightly provision, with 86.49% SVR₁₂ and 40 received fortnightly provision and psychological intervention at treatment initiation, with 92.50% SVR₁₂ . Analysis showed no significant difference in SVR₁₂ (p = 0.67). This study did not demonstrate a statistically significant difference in cure rate between groups. This provides evidence of the non-inferiority of fortnightly dispensing of direct-acting antivirals (DAAs) compared to directly observed therapy among PWID. It suggests that tight control of adherence through directly observed therapy dispensing of DAAs among this population offers no therapeutic advantage. Therefore, less restrictive dispensing patterns can be used, tailored to patient convenience.

Exploring how hospitalization can alter hepatitis c virus treatment prioritization and trajectories in people who use drugs: A qualitative analysis

Background: People who use drugs (PWUD) have high rates of hepatitis C virus (HCV) infection. Hospitalization can be a time for PWUD to engage in addiction treatment, but little is known about how hospitalization shapes HCV treatment readiness. We aimed to describe how hospitalization and addiction medicine consult service (AMCS) can alter HCV prioritization of inpatient PWUD with HCV. Methods: We conducted a qualitative study consisting of semi-structured interviews (n = 27) of hospitalized adults with addiction and HCV infection seen by an AMCS at a single, urban, academic center. Interviews were audio-recorded, transcribed, and coded iteratively at the semantic level, and analyzed for themes. Results: Of the 27 participants, most identified as Caucasian (85%), male gender (67%), and they primarily used opioids (78%); approximately half (48%) reported HCV diagnosis over 5 years ago. We identified three main themes around hospitalization altering the prioritizations and HCV treatment preferences for PWUD: (1) HCV treatment non-engaged (2) HCV treatment urgency, and (3) HCV treatment in the future. Those wanting to treat HCV-whether urgently or in the future-shared the overlapping theme of hospitalization as a reachable moment for their addiction and HCV. These participants recognized the long-term benefits of addressing HCV and connected their hospitalization to substance use. Conclusion: In our study, PWUD with HCV expressed varying and competing priorities and life circumstances contributing to three main HCV treatment trajectories. Our results suggest ways hospitalization can serve as an HCV touchpoint for PWUD, especially in the context of addressing substance use, and could be used when designing and implementing targeted interventions to improve the HCV care continuum for PWUD.

"That was quick, simple, and easy": Patient perceptions of acceptability of point-of-care hepatitis C RNA testing at a reception prison

INTRODUCTION

Current diagnostic pathways require multiple healthcare provider visits and lead to a drop-off in the hepatitis C virus (HCV) testing and treatment care cascade. In prison settings, frequent transitioning between prisons and the community further reduces uptake of testing and treatment. The PIVOT study evaluated a 'one-stop-shop' intervention integrating point-of-care HCV RNA testing, Fibroscan®-based liver disease assessment, and treatment prescription at a reception prison in Australia. This qualitative sub-study was undertaken to assess patient acceptability of point-of-care HCV RNA testing in the reception prison setting.

METHODS

Twenty-four men in prison enrolled in the PIVOT study participated in semi-structured interviews; all of whom had undergone point-of-care HCV RNA testing in the PIVOT study. Patients were purposefully selected to ensure comparable representation of people with and without a history of injecting drug use and people with and without prior HCV testing experience (standard venepuncture). Sekhon's Theoretical Framework of Acceptability, consisting of seven components (affective attitude, burden, ethicality, intervention coherence, opportunity cost, perceived effectiveness, and self-efficacy), informed this qualitative analysis.

RESULTS

Acceptability of fingerstick point-of-care HCV RNA testing was evident across four components: affective attitude, burden, self-efficacy, and perceived effectiveness. Patients described point-of-care testing as "quick and easy" (affective attitude), while swift results were viewed as alleviating anxiety associated with long wait times for standard pathology (burden). Patients averse to venepuncture (e.g., fear of needles or poor vein health) found the fingerstick method accessible, thereby enabling participation in HCV screening (self-efficacy). Participants attributed confidence in test results predominantly due to trust in the healthcare system or trust in the personnel administering the test (perceived effectiveness).

CONCLUSION

People entering custody perceive fingerstick HCV RNA point-of-care testing to be an acceptable method and preferred this method to standard HCV testing via venepuncture. In light of these findings, prison health authorities should consider the role of opt-out point-of-care HCV RNA testing upon prison entry.

Eliminating hepatitis C in a rural Appalachian county: protocol for the Kentucky Viral Hepatitis Treatment Study (KeY Treat), a phase IV, single-arm, open-label trial of sofosbuvir/velpatasvir for the treatment of hepatitis C

OBJECTIVES

The overall goal of the Kentucky Viral Hepatitis Treatment Study (KeY Treat) is to eliminate hepatitis C transmission from a county in Appalachian Kentucky by removing the barriers to accessing hepatitis C virus (HCV) treatment.

METHODS/ANALYSIS

KeY Treat is a phase IV, open-label, single-arm clinical trial of sofosbuvir/velpatasvir (SOF/VEL) for the treatment of viraemic HCV infections. Those eligible for KeY Treat are at least 18 years of age, viraemic and are residents of the target county. Pregnant women are not eligible. Rapid HCV RNA screening is used to determine eligibility, and those with a quantifiable viral load (VL) consenting to participate initiate SOF/VEL on the same day. All pharmacologic treatment and related medical care is provided free of charge using a non-specialist provider model. Follow-up visits occur at 2, 6 and 12 weeks during treatment to assess medication adherence (measured via VL and self-report), side effects and engagement in risk behaviours. Post-treatment visits occur at 12 weeks (sustained virologic response (SVR12) visit), 6 months and 12 months post-treatment completion to assess re-infection. A control county has also been identified, and prevalence and incidence of chronic HCV infections will be compared with the target community longitudinally. The primary outcome to assess elimination is SVR12. However, several outcomes will be measured to assess the effectiveness of removing the barriers to HCV treatment, including treatment entry, completion and re-infection. Analyses will be conducted via a generalised linear model framework that can incorporate flexible covariate adjustment and multiple outcome types with a compatible link function. Mathematical modelling will be completed assessing the impact and cost-effectiveness of the intervention.

ETHICS AND DISSEMINATION

KeY Treat has been approved by the Institutional Review Board at the University of Kentucky. Results from KeY Treat will be presented at conferences and published in peer-reviewed journals.

Personal, provider and system level barriers and enablers for hepatitis C treatment in the era of direct-acting antivirals: Experiences of patients who inject drugs accessing treatment in general practice settings in Australia

Direct acting antiviral (DAA) treatment has made the elimination of hepatitis C virus (HCV) a realisable global public health goal and people who inject drugs are a key target population. This study investigates barriers and enablers to DAA treatment of HCV in general practice settings in Australia, from the patient perspective. Semi-structured interviews were conducted with 28 patients; of these patients, seventeen participants were currently on opioid agonist therapy, and four were currently injecting drugs. Thematic data analysis was undertaken and a personal, provider and systems framework was used to describe the barriers and enablers to DAA treatment. Results suggest a range of initiatives are required to support the uptake of DAA in general practice settings. These include the provision of formalised peer information and support, and increasing the accessibility of blood tests and liver assessment on-site. Further, there remains a need to address stigma and discrimination affecting people who inject drugs in community healthcare settings.

Prescribing direct-acting antivirals to treat hepatitis C virus in a general practice setting in Australia: 'so why not do it'?

BACKGROUND

The recent implementation of a scheme to provide universal access to direct-acting antiviral (DAA) medication to treat hepatitis C virus (HCV) places Australia in a unique position to reach global HCV elimination goals. To achieve this, increasing the uptake and success of DAA treatment in general practice settings is essential.

AIMS

To explore current enablers and residual barriers to HCV treatment in general practice settings in the post-interferon era from both general practitioner (GP) and patient perspectives.

METHODS

Semi-structured interviews with 11 GP and 27 patients were conducted to draw out both challenges and facilitators particularly relevant to DAA uptake and treatment journeys.

RESULTS

Key enablers for successful treatment identified by this study included peer-led GP support and skill development, utilisation of electronic reminder systems, trusting relationships with patients and engaging with patients' social and family networks. Barriers related to accessible testing facilities and knowledge and confidence with DAA treatment continue to limit GP-led treatment.

CONCLUSIONS

Despite a universal access scheme, barriers to DAA prescription in general practice settings remain. These include access to fibrosis testing and GP confidence in DAA prescription. Strengthening peer-led GP skill development and utilisation of electronic reminder systems may help GP prioritise HCV treatment. Access to fibrosis testing and pathology services with no out-of-pocket costs to patients, particularly in outer-metropolitan areas, should be urgently addressed.

Exploring and understanding HCV patient journeys- HEPCARE Europe project

Background

Hepatitis C Virus (HCV) is a leading cause for chronic liver diseases worldwide. The European Union and World Health Organization aspire to eliminate HCV by 2030. However, among at-risk populations, including, homeless people, prisoners and People Who Inject Drugs, access to diagnosis and treatment is challenging. Hepcare Europe is an integrated model of care developed to address this by assessing potential reasons for these restrictions and determining measures needed to improve HCV diagnosis, treatment and access to care within different communities.

Objectives

HepCare Europe is an EU-supported project involving collaboration between five institutions in: Ireland, United Kingdom, Spain and Romania. We aim to explore the journey of care experienced by those living with HCV with a focus on previous care disruptions (loss to follow up) and the new HepCare Europe Programme.

Methods

Research teams conducted semi-structured interviews with patients who accessed services through HepCare Europe thus, patients were recruited by purposeful sampling. Patients interviewed had received, or were in the final weeks of receiving, treatment. The interviews were audio recorded, transcribed and translated into English, and sent to the Dublin team for inductive thematic analysis. Researchers from the HepCare Europe research team coded the data separately, then together.

Results

Common themes are introduced to present similarities, following individual site themes to highlight the importance of tailored interventions for each country. Key themes are: 1) Hepatitis C patients lost to follow up 2) HepCare improved access to treatment and 3) the need for improved HCV education. Individual themes also emerged for each site. These are: Ireland: New opportunities associated with achieving Sustained Virologic Responses (SVR). Romania: HCV is comparatively less crucial in light of Human Immunodeficiency Viruses (HIV) coinfections. UK: Patients desire support to overcome social barriers and Spain: Improved awareness of HCV, treatment and alcohol use.

Conclusion

This study identified how the tailored HepCare interventions enabled improved HCV testing and linkage to care outcomes for these patients. Tailored interventions that targeted the needs of patients, increased the acceptability and success of treatment by patients. HepCare demonstrated the need for flexibility in treatment delivery, and provided additional supports to keep patients engaged and educated on new treatment therapies.

Innovations in Hepatitis C Screening and Treatment

New therapies offer hope for a cure to millions of persons living with hepatitis C virus (HCV) infection. HCV elimination is a global goal that will be difficult to achieve using the traditional paradigms of diagnosis and care. The current standard has evolved toward universal HCV screening and treatment, to achieve elimination goals. There are several steps between HCV diagnosis and cure with major barriers along the way. Innovative models of care can address barriers to better serve hardly reached populations and scale national efforts in the United States and abroad. Herein, we highlight innovative models of HCV care that aid in our progress toward HCV elimination.

Treatment outcomes and costs of a simplified antiviral treatment strategy for hepatitis C among monoinfected and HIV and/or hepatitis B virus-co-infected patients in Myanmar

Access to hepatitis C virus (HCV) testing and treatment is limited in Myanmar. We assessed an integrated HIV and viral hepatitis testing and HCV treatment strategy. Sofosbuvir/velpatasvir (SOF/VEL) ± weight-based ribavirin for 12 weeks was provided at three treatment sites in Myanmar and sustained virologic response (SVR) assessed at 12 weeks after treatment. Participants co-infected with HBV were treated concurrently with tenofovir. Cost estimates in 2018 USD were made at Yangon and Mandalay using standard micro-costing methods. 803 participants initiated SOF/VEL; 4.8% were lost to follow-up. SVR was achieved in 680/803 (84.6%) by intention-to-treat analysis. SVR amongst people who inject drugs (PWID) was 79.7% (381/497), but 92.5% among PWID on opioid substitution therapy (OST) (74/80), and 97.4% among non-PWID (298/306). Utilizing data from 492 participants, of whom 93% achieved SVR, the estimated average cost of treatment per patient initiated was $1030 (of which 54% were medication costs), with a production cost per successful outcome (SVR) of $1109 and real-world estimate of $1250. High SVR rates were achieved for non-PWID and PWID on OST. However, the estimated average cost of the intervention (under the assumption of no genotype testing and reduced real-world effectiveness) of $1250/patient is unaffordable for a national elimination strategy. Reductions in the cost of antivirals and linkage to social and behavioural health services including substance use disorder treatment to increase retention and adherence to treatment are critical to HCV elimination in this population.

Determinants of stigma among patients with hepatitis C virus infection

Stigma around hepatitis C virus (HCV) infection is an important and understudied barrier to HCV treatment and elimination. The determinants of HCV-related stigma, including the impacts of stage of HCV treatment (ie spontaneously cleared; diagnosed, untreated; previously treated, not cured; currently being treated; and treated, cured) and coinfection with human immunodeficiency virus (HIV), remain unknown. To address these gaps, we conducted a cross-sectional study among patients with a history of HCV infection (n = 270) at outpatient clinics in Philadelphia from July 2018 to May 2019. We evaluated stigma using the validated HCV Stigma Scale, adapted from the Berger HIV Stigma Scale. Associations among HCV-related stigma and hypothesized demographic, behavioural, and clinical risk factors were evaluated by multivariable linear regression. Most participants (95.5%) experienced HCV-related stigma. Mean stigma scores did not differ significantly between HCV-monoinfected and HIV/HCV-coinfected participants (P = .574). However, we observed significant interactions between HIV status and multiple determinants; therefore, we stratified analyses by HIV status. Among HIV/HCV-coinfected participants, previous HCV treatment without cure, female gender, Hispanic/Latinx ethnicity and some college education were significantly associated with higher HCV-stigma scores. An annual income of $10 000-$40 000 was associated with significantly lower stigma scores. No significant associations were observed among HCV-monoinfected participants. We found that most participants experienced stigma associated with HCV diagnosis. While stigma scores were similar between HCV-monoinfected and HIV/HCV-coinfected participants, the determinants associated with HCV stigma differed by HIV status. Understanding how experiences of stigma differ between HCV-monoinfected and HIV/HCV-coinfected patients may aid in the development of targeted interventions to address the HCV epidemic.

'There is no such thing as getting sick justly or unjustly' - a qualitative study of clinicians' beliefs on the relevance of personal responsibility as a basis for health prioritisation

BACKGROUND

Concerns have been raised regarding the reasonableness of using personal health responsibility as a principle or criterion for setting priorities in healthcare. While this debate continues, little is known about clinicians' views on the role of patient responsibility in clinical contexts. This paper contributes to the knowledge on the empirical relevance of personal responsibility for priority setting at the clinical level.

METHODS

A qualitative study of Norwegian clinicians (n = 15) was designed, using semi-structured interviews with vignettes to elicit beliefs on the relevance of personal responsibility as a basis for health prioritisation. Sampling was undertaken purposefully. The interviews were conducted in three hospital trusts in South-Eastern Norway between May 2018 and February 2019 and were analysed with conceptually driven thematic analysis.

RESULTS

The findings suggest that clinicians endorsed a general principle of personal health responsibility but were reluctant to introduce personal health responsibility as a formal priority setting criterion. Five main objections were cited, relating to avoidability, causality, harshness, intrusiveness, and inequity. Still, both retrospective and prospective attributions of personal responsibility were perceived as relevant in specific clinical settings. The most prominent argument in favour of personal health responsibility was grounded in the idea that holding patients responsible for their conduct would contribute to the efficient use of healthcare resources. Other arguments included fairness to others, desert and autonomy, but such standpoints were controversial and held only marginal relevance.

CONCLUSIONS

Our study provides important novel insights into the clinicians' beliefs about personal health responsibility improving the empirical knowledge concerning its fairness and potential applications to healthcare prioritisation. These findings suggest that although personal health responsibility would be difficult to implement as a steering criterion within the main priority setting framework, there might be clinical contexts where it could figure in prioritisation practices. Additional research on personal health responsibility would benefit from considering the multiple clinical encounters that shape doctor-patient relationships and that create the information basis for eligibility and prioritisation for treatment.

Accessibility of Needle and Syringe Programs and Injecting and Sharing Risk Behaviors in High Hepatitis C Virus Prevalence Settings

Background: Access to healthcare services is a basic human right. Objective: The main purpose of this study is to assess the association between accessibility of needle and syringe programs (NSP) and injecting and sharing risk behaviors. Methods: A cross-sectional study employed respondent-driving sampling (RDS) to recruit a sample of 634 people who inject drugs (PWID) from three provinces, Golestan, Ardabil, and Sistan and Baluchestan, in Iran between November 2018 and February 2019. Participants completed a questionnaire based on the WHO Drug Injecting Study Phase II survey. Results: Participants reported their accessibility of NSP services as low (6%), middle (19%), and high (75%) in the past 2 months at the time of the survey. PWID who had increased access to NSP services were less likely to report utilization of used cooker (aOR = 1.40; CI 95% 0.99-1.82), cotton (aOR = 1.30; CI 95% 0.79-1.81), and water (aOR = 1.07; CI 95% 0.89-1.26), receptive needle/syringe sharing (aOR= 1.86, 95% CI 1.69-2.03), and distributive needle/syringe sharing (aOR= 1.09, 95% CI 0.81-1.37). Conclusions/Importance: There is evidence of inequality in PWID's access to health care as they relate to the prevention of HCV transmission. An understanding of both the social determinants and prevention of injecting and sharing risk behaviors seeks to connect HCV risk reduction within the context of human rights and vulnerability.

Randomised controlled trial conducted in injecting equipment provision sites to compare the effectiveness of different hepatitis C treatment regimens in people who inject drugs: A Direct obserVed therApy versus fortNightly CollEction study for HCV treatment-ADVANCE HCV protocol study

INTRODUCTION

Hepatitis C is a blood-borne virus (HCV) that can seriously damage the liver and is spread mainly through blood-to-blood contact with an infected person. Over 85% of individuals who have HCV in Scotland became infected following injecting drug use. Since people who inject drugs (PWID) are the main source of new infections, theoretical modelling has suggested that treatment of HCV infection in PWID may effectively reduce HCV prevalence and accomplish elimination. This protocol describes a clinical trial delivering HCV treatment within injecting equipment provision sites (IEPS) in Tayside, Scotland.

METHODS AND ANALYSIS

PWID attending IEPS are tested for HCV and, if they are chronically infected with HCV and eligible, invited to receive treatment within the IEPS. They are randomised to one of three treatment regimens; daily observed treatment, treatment dispensed every 2 weeks and treatment dispensed every 2 weeks together with an adherence psychological intervention (administered before treatment begins). The primary outcome is comparison of the rate of successful treatment (SVR₁₂) in each treatment group. Secondary analyses include assessment of adherence, reinfection rates, viral resistance to treatment and interaction of the treatment with illicit drugs.

ETHICS AND DISSEMINATION

The ADVANCE (A Direct obserVed therApy versus fortNightly CollEction) HCV trial was given favourable opinion by East of Scotland Research Ethics Committee (LR/17/ES/0089) prior to commencement.

Elimination of hepatitis C virus infection among people who use drugs: Ensuring equitable access to prevention, treatment, and care for all

There have been major strides towards the World Health Organization goal to eliminate hepatitis C virus (HCV) infection as a global public health threat. The availability of simple, well-tolerated direct-acting antiviral therapies for HCV infection that can achieve a cure in >95% of people has provided an important tool to help achieve the global elimination targets. Encouragingly, therapy is highly effective among people receiving opioid agonist therapy and people who have recently injected drugs. Moving forward, major challenges include ensuring that new infections are prevented from occurring and that people who are living with HCV are tested, linked to care, treated, receive appropriate follow-up, and have equitable access to care. This editorial highlights key themes and articles in a special issue focusing on the elimination of HCV among people who inject drugs. An overarching consideration flowing from this work is how to ensure equitable access to HCV treatment and care for all. This special issue maps the field in relation to: HCV prevention; the cascade of HCV care; strategies to enhance testing, linkage to care, and treatment uptake; and HCV treatment and reinfection. In addition, papers draw attention to the 'risk environments' and socio-ecological determinants of HCV acquisition, barriers to HCV care, the importance of messaging around the side-effects of new direct-acting antiviral therapies, the positive transformative potential of treatment and cure, and the key role of community-based drug user organizations in the HCV response. While this special issue highlights some successful efforts towards HCV elimination among people who inject drugs, it also highlights the relative lack of attention to settings in which resources enabling elimination are scarce, and where elimination hopes and potentials are less clear, such as in many low and middle income countries. Strengthening capacity in areas of the world where resources are more limited will be a critical step towards ensuring equity for all so that global HCV elimination among PWID can be achieved.

Changes to the national strategies, plans and guidelines for the treatment of hepatitis C in people who inject drugs between 2013 and 2016: a cross-sectional survey of 34 European countries

Background

Hepatitis C virus (HCV) infection is the leading cause of cirrhosis, end-stage liver disease and hepatocellular carcinoma (HCC) worldwide. In Europe, people who inject drugs (PWID) represent the majority of HCV infections, but are often excluded from treatment. The aim of this study was to report on national HCV strategies, action plans and guidelines in European countries that include HCV treatment for the general population as well as for PWID. Data on access to direct-acting antivirals (DAAs) were also collected.

Methods

In 2016, 38 non-governmental organisations, universities and public health institutions that work with PWID in 34 European countries were invited to complete a 16-item online survey about current national HCV treatment policies and guidelines. Data from 2016 were compared to those from 2013 for 33 European countries, and time trends are presented. Differences in the data were analysed. Data from 2016 on general access to DAAs in PWID are presented separately.

Results

The response rate was 100%. Fourteen countries (42%) reported having a national HCV strategy covering HCV treatment; 12 of these addressed HCV treatment for PWID. Respondents from ten countries (29%) reported having a national HCV action plan. PWID were specifically included in seven of them. Twenty-nine countries (85%) reported having national HCV treatment guidelines. PWID were specifically included in 23 (79%) of them. Compared to 2013, respondents reported that an additional seven countries (25%) had national strategies, an additional eight countries (29%) had action plans and an additional six countries (19%) had HCV treatment guidelines. However, PWID were not included in two, four and six of those countries, respectively. DAAs were reported to be available in 91% of the study countries, with restrictions reported in 71% of them.

Conclusion

Respondents reported that fewer than half of the European countries in this study had a national HCV strategy and/or action plan, with even fewer including PWID. However, when compared to 2013, the number of such countries had slightly increased. Although PWID are often addressed in clinical guidelines, strategic action is needed to increase access to HCV treatment for this group and the situation should be regularly monitored.

Hepatitis C services at harm reduction centres in the European Union: a 28-country survey

Background

In the context of the WHO’s 2016 Viral Hepatitis Strategy and the introduction of treatment that can cure more than 95% of cases with hepatitis C virus (HCV) infection, the European Joint Action on HIV and Co-infection Prevention and Harm Reduction (HA-REACT) undertook a study in the member states of the European Union (EU). It aimed to determine service providers’ understanding of the current services in their respective countries and the barriers experienced by PWID in accessing HCV testing, care and treatment services in their country.

Methods

In 2017, 38 purposively selected harm reduction service providers completed a 26-item English-language online survey addressing the availability, accessibility and funding of HCV services at harm reduction centres. HCV-related data and reported findings were extracted by country or by responding organization.

Results

Responses were received from all EU member states. Respondents from 23 countries reported that HCV tests are offered by harm reduction services in their countries, and eight countries reported that addiction specialists in their countries are able to prescribe HCV therapy. Almost half of the respondents (45%) said that their respective organizations had established referral systems with centres providing HCV treatment.

Conclusions

Not all EU member states have harm reduction services that provide HCV tests, and many do not have established referral systems with treatment providers. Moreover, the inability of addiction specialists to prescribe HCV treatment points to missed opportunities to make treatment more accessible. Further, discrepancies were noted between the available HCV services and stakeholders’ knowledge about their availability.

Safety and efficacy of glecaprevir/pibrentasvir in patients with chronic hepatitis C genotypes 1-6 receiving opioid substitution therapy

BACKGROUND

International guidelines recommend treatment of hepatitis C virus (HCV) infection in people who inject drugs (PWID), including those on opioid substitution therapy (OST). The pangenotypic combination of glecaprevir and pibrentasvir has shown high sustained virologic response at post-treatment Week 12 (SVR12) in clinical trials. Herein, we evaluate the safety and efficacy of glecaprevir/pibrentasvir in patients receiving OST.

METHODS

Pooled data from patients with HCV genotypes 1-6 who were treated with glecaprevir/pibrentasvir for 8, 12, or 16 weeks in eight Phase 2 and 3 trials were categorized by use of OST. Treatment completion, treatment adherence, SVR12, adverse events (AEs), and laboratory abnormalities were evaluated for patients receiving and not receiving OST.

RESULTS

Among 2256 patients, 157 (7%) were receiving OST. Compared with patients not receiving OST, OST patients were younger (mean age, 46.8 vs 52.8 years), male (69% vs 54%), white (93% vs 80%), HCV treatment-naïve (86% vs 72%), had HCV genotype 3 (60% vs 26%), and had a history of depression or bipolar disorder (43% vs 19%). Most patients completed (OST: 98% [n/N = 154/157]; non-OST: 99% [n/N = 2070/2099]) and were adherent (received ≥90% of study drug doses) to glecaprevir/pibrentasvir treatment (OST: 98% [n/N = 121/123]; non-OST: 99% [n/N = 1884/1905] among patients with available data). In the intention-to-treat population, SVR12 rates in OST and non-OST patients were 96.2% (n/N = 151/157; 95% CI 93.2-99.2) and 97.9% (n/N = 2055/2099; 95% CI 97.3-98.5), respectively. For OST patients, reasons for nonresponse included virologic relapse (<1%; n = 1), premature study drug discontinuation (<1%; n = 1), and loss to follow-up (3%; n = 4). AEs occurring in ≥10% of OST patients were headache, fatigue, and nausea. Drug-related serious AEs, AEs leading to study drug discontinuation, and Grade 3 or higher laboratory abnormalities were infrequent in both groups (<1%). No HCV reinfections occurred through post-treatment Week 12.

CONCLUSION

Glecaprevir/pibrentasvir is highly efficacious and well tolerated in HCV-infected patients receiving OST.

Hepatitis C Testing, Status and Treatment among Marginalized People Who Use Drugs in an Inner City Setting: An Observational Cohort Study

BACKGROUND

Chronic hepatitis C virus (HCV) infection is common among people who inject drugs (PWID) and is associated with morbidity and premature death. Although HCV can be cured, treatment may be inaccessible. We studied HCV testing, status and treatment among marginalized people who use drugs in Ottawa, Canada, a setting with universal insurance coverage for physician services.

METHODS

We analyzed data from the Participatory Research in Ottawa: Understanding Drugs study, a cross-sectional, peer-administered survey of people who use drugs from 2012 to 2013. We linked responses to population-based health administrative databases and used multivariable Poisson regression to identify factors independently associated with self-reported HCV testing, self-reported positive HCV status, and database-determined engagement in HCV treatment.

RESULTS

Among 663 participants, 562 (84.8%) reported testing for HCV and 258 (45.9%) reported HCV-positive status. In multivariable analysis, HCV-positive status was associated with female gender (RR 1.27; 95%CI 1.04 to 1.55), advancing age (RR 1.03/year; 95%CI 1.02 to 1.04), receiving disability payments (RR 1.42; 95%CI 1.06 to 1.91), injecting drugs (RR 5.11; 95%CI 2.64 to 9.91), ever injecting with a used needle (RR 1.30; 95%CI 1.12 to 1.52), and ever having taken methadone (RR 1.26; 95%CI 1.05 to 1.52). Of HCV positive participants, 196 (76%) were engaged in primary care but only 23 (8.9%) had received HCV therapy. Conclusions/Importance: Although HCV testing and positive status rates are high among PWID in our study, few have received HCV treatment. Innovative initiatives to increase access to HCV treatment for PWID are urgently needed.

Change in injecting behaviour among people treated for hepatitis C virus: The role of intimate partnerships

Injecting behaviour in people who inject drugs is the main risk factor for hepatitis C virus (HCV) infection. Psychosocial factors such as having a partner who injects drugs and living with other drug users have been associated with increases in injecting risk behaviour. This study aimed to investigate changes in injecting behaviour during treatment for HCV infection whilst exploring the role of psychosocial factors on patients' injecting behaviour. Eradicate-C was a single-centred clinical trial (ISRCTN27564683) investigating the effectiveness of HCV treatment within the injecting drug-using population between 2012 and 2017. A total of 94 participants completed up to 24 weeks of treatment, with social and behavioural measures taken at different intervals throughout treatment. Data for 84 participants were analysed retrospectively to explore mechanisms of potential behavioural changes which had occurred during treatment. Injecting frequency reduced significantly between baseline (week 1) and every 4-weekly interval until week 26. Not being on opiate substitution therapy (OST) was associated with a statistically significant decrease in injecting frequency, χ² (1) = 10.412, P = 0.001, as was having a partner who also used drugs, in particular when that partner was also on treatment for HCV infection, Z = -2.312, P = 0.021. Treating a hard-to-reach population for HCV infection is not only possible, but also bears health benefits beyond treatment of HCV alone. Enrolling couples on HCV treatment when partners are sero-concordant has shown enhanced benefits for reduction in injecting behaviour. Implications for practice are discussed.

Variation in hepatitis C virus treatment uptake between Canadian centres in the era of direct-acting antivirals

BACKGROUND

Patients co-infected with HIV and hepatitis C virus (HCV) are a priority target for HCV treatment. The simplicity and efficacy of direct-acting antivirals (DAA) should help overcome patient, provider, and structural barriers to scaling up treatment.

METHODS

We estimated between-centre variation in DAA treatment uptake among 1734 patients enrolled at the 18 centres of the Canadian Co-Infection Cohort-a prospective cohort of adults co-infected with HIV and HCV. We then compared this variation to that observed during the interferon era. Time to treatment uptake was modeled using a Weibull time-to-event model adjusting for centre and patient characteristics thought to have an impact on treatment initiation in the DAA era.

RESULTS

At the time of administrative censoring (December 31, 2016), 981 cohort participants were eligible for second-generation DAA therapy (HCV RNA positive after November 21, 2013) of whom 278 initiated DAAs (16 patients per 100 person-years). Patients with low monthly income, Indigenous ethnicity, recent injection drug use, HCV genotype 3, or unknown HCV genotype were less likely to start treatment. After adjusting for patient characteristics, the estimated between-centre variance (σ²) was 0.29 (95% credible interval [CrI]: 0.09-0.89), considerably lower than during the interferon era (σ² = 0.87, 95% CrI: 0.49-1.5). This between-centre variance was further reduced by the addition of centre-level effects for jurisdiction (σ² = 0.15, 95% CrI: 0.02-0.60).

CONCLUSION

Much of the variation in treatment uptake between centres can now be attributed to regional differences. This suggests that after the introduction of DAAs, treatment barriers have shifted towards prescribing and reimbursement restrictions based on liver fibrosis, which vary by jurisdiction. The removal of these restrictions, however, will need to be paired with strategies to overcome patient-level barriers, which continue to prevent marginalized people and active substance users from accessing treatment.

Estimating HIV and HCV prevalence among people who inject drugs in 5 Ukrainian cities using stratification-based respondent driven and random sampling

BACKGROUND

Ukraine, a country of 45.5 million people, has one of the most volatile HIV and HCV epidemics in the world. In this paper, we estimate the prevalence of HIV and HCV among PWID in five Ukrainian cities.

METHODS

A cross-sectional study was conducted in 2014-2015, based on stratified hybrid sampling with random and respondent driven sampling in five cities: Kyiv, Odesa, Mykolaiv, Dnipro and Lviv. Using data on HIV and HCV antibody testing from 1613 respondents, we evaluate selection bias in the sampling methods by analyzing spatial and network patterns of sampling processes. We develop and apply inverse probability weights in order to estimate the HIV and HCV prevalence in each city, as well as in the overall sample.

FINDINGS

The aggregate HIV prevalence for the five cities is 35.1% (95% CI: 29.5%-38.5%) but this varied considerably by city: in Kyiv the HIV prevalence is 26.6% (95% CI: 20.3.8%-33.4%), in Odesa - 38.2% (95% CI: 29.8% and 47.1%), in Mykolaiv - 42.0% (95% CI: 34.3%-49.2%), in Dnipro - 58.8% (95% CI: 52.2%-65.8%), and in Lviv 24.6% (95% CI: 18.8%-30.8%). The aggregate HCV prevalence estimate for the five cities is 58.6% (95% CI: 54.9%-61.7%). The highest HCV prevalence is estimated in Kyiv - 84.8% (95% CI: 78.5%-90.1%). HCV prevalence in Odesa is the lowest and estimated to be 36.5% (95% CI: 29.5%-45.1%), in Mykolaiv - 49.1% (95% CI: 41.5%-57.0%), in Dnipro - 56.1% (95% CI: 50.3%-63.4%) and in Lviv 38.5% (95% CI: 31.8%-45.0%).

CONCLUSIONS

Monitoring behavioral and health outcomes of PWID on a regular basis is necessary for determining prevention and treatment priorities for HIV and HCV infections in Ukraine and elsewhere. The heterogeneity of the local epidemics provides insights into the best prevention and treatment strategies to be deployed in low-resource settings.

Direct acting antiviral-based treatment of hepatitis C virus infection among people who inject drugs in Georgia: A prospective cohort study

BACKGROUND

People who inject drugs (PWID) are often excluded from HCV treatment programs due to concerns about their ability to adhere to care. Georgia has a high prevalence of HCV infection (5.4% of chronic cases in general population) with an epidemic concentrated among PWID. We evaluated adherence to care and sustained virologic response (SVR) among PWID in Georgia.

METHODS

In this observational study, participants with recent injecting drug use (previous 6 months) and chronic HCV attending a needle- and syringe-program were included. Participants received sofosbuvir and ribavirin +/- pegylated interferon, with peer-based support during treatment. The primary endpoint was undetectable HCV RNA 12 weeks post-treatment (SVR12). Factors associated with SVR were assessed using logistic regression.

RESULTS

Among 244 participants [HCV genotype (GT) 3, 52%; GT2, 25%; GT1, 19%; mixed GT, 4%]; 55% had cirrhosis. Overall, 24% were receiving OST and 50% injected drugs in the previous month. 98% (239 of 244) completed treatment, with 88% (210 of 239) having never delayed a medical appointment and 79% (189 of 239) never missing a dose of medication. Overall, SVR was 84.8% (207 of 244). SVR was 88.5% (207 of 234) among participants who attended 12-week follow up appointment for HCV RNA testing. In multivariate analyses, SVR was significantly associated with adherence (no missed doses) to treatment [vs. missed doses; adjusted OR (aOR) 2.77; 95% confidence interval (95%CI), 1.01-7.51), and genotype (vs. GT1; GT2, aOR 0.27; 95%CI 0.06-1.21; GT3, aOR 1.09; 95%CI 0.27-4.50; and mixed GT, aOR 0.14; 95%CI 0.02-0.97).

CONCLUSION

In this real-life study in a middle-income country, PWID treated for HCV and receiving a simple peer-support intervention demonstrated an excellent treatment response and good adherence, not associated with injecting drug use during treatment and OST at treatment initiation.

Hepatitis C cascade of care among people who inject drugs in Vancouver, Canada

BACKGROUND

People who inject drugs (PWID) have high rates of hepatitis C virus (HCV) infection. Little is known about the rates of diagnosis and treatment for HCV among PWID. Therefore, this study aims to characterize the cascade of care in Vancouver, Canada, to improve HCV treatment access and delivery for PWID.

METHODS

Data were derived from 3 prospective cohort studies of PWID in Vancouver, Canada, between December 2005 and May 2015. The progression of participants was identified through 5 steps in the cascade of care: (1) chronic HCV; (2) linkage to HCV care; (3) liver disease assessment; (4) initiation of treatment; and (5) completion of treatment. Predictors of undergoing liver disease assessment for HCV treatment were identified using a multivariable extended Cox regression model.

RESULTS

Among 1571 participants with chronic HCV, 1359 (86.5%) had ever been linked to care, 1257 (80.0%) had undergone liver disease assessment, 163 (10.4%) had ever started HCV treatment, and 71 (4.5%) had ever completed treatment. In multivariable analyses, human immunodeficiency virus (HIV) seropositivity, use of methadone maintenance therapy, and hospitalization in the past 6 months were independently and positively associated with undergoing liver disease assessment (all P < .001), whereas daily heroin injection was independently and negatively associated with undergoing liver disease assessment (P < .001).

CONCLUSIONS

Among this cohort of PWID, few had been started on or completed treatment for HCV. These findings highlight the need to improve the prescribing of HCV treatment among PWID with active substance use.

Understanding hepatitis C intervention success-Qualitative findings from the HepCATT study

The United Kingdom has committed to eliminating viral hepatitis as a public health threat. Innovative interventions for marginalized populations are required to realize this goal. In 2016, the HepCATT study team implemented a complex hepatitis C (HCV) intervention in three English drug treatment services, with five controls. We report qualitative study findings from two intervention sites to explore intervention success and transferability potential. The intervention comprised multiple components, including a nurse facilitator, peer support and education initiatives. Qualitative data were generated at baseline (2014) and post-intervention (2016) at two sites through in-depth interviews, focus groups and observations. The 96 participants comprised drug service and intervention providers and clients with an injecting history. Data were triangulated and thematically analysed. Client engagement with a HCV treatment service rose from 16 at baseline to 147 in 2016. There was no comparable increase at the five control sites. Baseline testing and treatment barriers included the following: limited HCV knowledge; fear of diagnosis and treatment; precarious living circumstances and service-specific obstacles. Treatment engagement was aided by intervention timeliness; improved communication structures; personalized care; streamlined testing and treatment pathways; peer support. Multiple interrelated components influenced the increased levels of treatment engagement documented in HepCATT. The nurse facilitator, involved in implementation and innovation, was key to intervention success. Baseline barriers correspond with international literature-indicating transferability potential. Control data indicate that biomedical innovation alone is not sufficient to increase engagement among the most marginalized. Sustainable resourcing of community services is crucial to effect change.

Integrating hepatitis C and addiction care for people who inject drugs in the era of direct-acting antiviral therapy

As new, more tolerable and effective hepatitis C virus (HCV) treatments are available, there is a global need to consider how to maximize treatment access for groups who are most affected by HCV. A substantial number of people who inject drugs (PWID) are living with HCV, yet only a minority have received treatment. HCV treatment programs that are integrated into community-based addiction care may be a successful way to overcome barriers and increase access and uptake of HCV treatment for this population. Examples of successful HCV and addiction care integration in the community have been documented. However, potential challenges to integration exist and include changing healthcare provider roles, lack of stimulant use research and restrictive drug policies. Successful engagement of PWID in HCV care is critical step towards the elimination of HCV infection. Further research and efforts are needed in order to reach this goal.

Experiences with skin and soft tissue infections among people who inject drugs in Philadelphia: A qualitative study

OBJECTIVES

To understand how people who inject drugs (PWID) experience skin and soft tissue infections (SSTI) and make decisions to seek or delay medical treatment.

METHODS

We conducted semi-structured, in-depth interviews in 2015 with 19 PWID at a syringe exchange program in Philadelphia. We analyzed the data using standard qualitative techniques.

RESULTS

PWID described adequate knowledge about SSTI, although they could not always implement knowledge about SSTI prevention due to environmental constraints. Participants reported different experiences with incident SSTI. Some sought immediate medical care at initial presentation. Most, however, waited to seek care. Previous positive and negative healthcare experiences, both in general -including stigma and withdrawal- and specific to SSTI, influenced this decision. Among those who delayed medical care, some reported self-treatment, including increased drug use for pain control, and lancing and draining their own wounds.

CONCLUSION

Reducing the incidence of SSTI and promoting earlier treatment are important public health priorities. Both require ongoing attention and improvements to the environments in which PWID inject and receive care.

Short article: Alcohol and substance use, race, and insurance status predict nontreatment for hepatitis C virus in the era of direct acting antivirals: a retrospective study in a large urban tertiary center

OBJECTIVE

Direct acting antivirals (DAAs) have overcome many long-standing medical barriers to hepatitis C virus (HCV) treatment (i.e. host characteristics and medical contraindications) and treatment outcome disparities that were associated with interferon regimens. The public health and clinical benefit of current and forthcoming DAA discoveries will be limited if efforts are not made to examine racial, psychological, and socioeconomic factors associated with being treated with DAAs. This study examined racial, psychological, and socioeconomic factors that facilitate and inhibit patients receiving DAAs for HCV.

PATIENTS AND METHODS

This was a single-center retrospective cohort study at a large urban tertiary center of patients (n=747) who were referred for evaluation and treatment of HCV.

RESULTS

Sixty-eight percent of patients were non-Hispanic White, 31% were African American, and 1% were of other ethnicities. The majority of patients received treatment, but 29% (218/747) did not. Patients who were older [odds ratio (OR)=1.02, 95% confidence interval (CI): 1.01-1.04] and insured (OR=2.73, 95% CI: 1.12-6.97) were more likely to receive HCV treatment. Patients who were African American (OR=0.46, 95% CI: 0.46-1.06), used drugs (OR=0.09, 95% CI: 0.04-0.17), smoked (OR=0.55, 95% CI: 0.37-0.81), and used alcohol (OR=0.11, 95% CI: 0.06-0.20) were less likely to receive HCV treatment.

CONCLUSION

Though DAAs have eliminated many historically, long-standing medical barriers to HCV treatment, several racial, psychological and socioeconomic barriers, and disparities remain. Consequently, patients who are African American, uninsured, and actively use drugs and alcohol will suffer from increased HCV-related morbidity and mortality in the coming years if deliberate public health and clinical efforts are not made to facilitate access to DAAs.

Hepatitis C in a new therapeutic era: Recontextualising the lived experience

AIMS AND OBJECTIVES

To explore the experience of adults living with hepatitis C in a new era of interferon-free treatment.

BACKGROUND

Hepatitis C is a leading cause of morbidity and mortality worldwide, posing a significant challenge to global public health. Historically, the treatment of hepatitis C was poorly efficacious and highly demanding; however, more effective and tolerable therapies have become available in high-income nations in recent years. This is the first study to explore how these significant developments in the treatment of hepatitis C may have influenced the experience of those living with the virus, and their understanding of the disease.

DESIGN

A qualitative study underpinned by social phenomenological theory.

METHODS

Data were generated through semi-structured interviews with a purposive sample of 20 hepatitis C positive adults living in a large city in Scotland.

RESULTS

Thematic analysis identified three overriding themes. "Positioning hepatitis C" illustrated how the disease was understood within wider sociocultural, medical and politico-economic contexts. "Beyond a physical burden" emphasised the emotional aspect of infection, and "a new uncertainty" revealed participants' cautious response to the advances in hepatitis C therapy.

CONCLUSIONS

Interthematic discourse portrayed the new era of hepatitis C treatment as holding little sway over constructions of the illness, as narratives resonated with previous studies. Such unmoving "lay" understandings of hepatitis C may pose potential barriers to the new therapeutic era from reaching its full potential.

RELEVANCE TO CLINICAL PRACTICE

How people living with the virus perceive and understand hepatitis C can have an adverse impact on their engagement with care and treatment. Whilst global medical discourse eulogises the arrival of a new era of therapy, there remain significant challenges for nurses engaging those with hepatitis C in therapeutic pathways.

Perceived benefits of the hepatitis C peer educators: a qualitative investigation

BACKGROUND

Although opioid-dependent patients are disproportionately impacted by hepatitis C (HCV), many do not receive treatment. In addition to HCV treatment-access barriers, substance-using patients may be reluctant to pursue treatment because of wariness of the medical system, lack of knowledge, or stigma related to HCV treatment. Implementation of a formal peer education program is one model of reducing provider- and patient-level barriers to HCV treatment, by enhancing mutual trust and reducing stigma.

METHODS

We used thematic qualitative analysis to explore how 30 HCV patients and peer educators perceived a HCV peer program within an established methadone maintenance program in the USA.

RESULTS

Participants unanimously described the program as beneficial. Participants described the peer educators' normalization and dispelling of myths and fears around HCV treatment, and their exemplification of HCV treatment success, and reductions in perceived stigma. Peer educators described personal benefits.

CONCLUSIONS

These findings indicate that HCV peer educators can enhance HCV treatment initiation and engagement within opioid substitution programs.

Implementing and scaling up HCV treatment services for people who inject drugs and other high risk groups in Ukraine: An evaluation of programmatic and treatment outcomes

BACKGROUND

HCV prevalence estimates among people who inject drugs (PWID) in Ukraine is high (60-90%), yet barriers to HCV treatment and care remain substantial including limited access to direct acting antiviral (DAA) medications. A feasibility scale-up project implemented HCV treatment in community-based settings to improve access to DAA treatment for key populations in this context.

METHODS

Using program-level data and verified medical records, we describe the development, implementation processes and outcomes for HCV treatment for PWID and other risks groups. Most participants (76%) received a combination of sofosbuvir, pegylated interferon, and ribavirin for 12 weeks. Treatment enrollment started in June 2015; the first two waves are reported. Data on demographics, HIV characteristics, HCV genotype and RNA levels, including sustained virologic response (SVR) were obtained from verified medical records. We used logistic regression to examine the independent correlates of achieving a SVR.

RESULTS

The project was implemented in 19 healthcare institutions from 16 regions of Ukraine, mainly within AIDS specialty centers. Our analytical sample included 1126 participants who were mostly men (73%) and the majority were HIV co-infected (79%). Treatment retention was 97.7%; the proportions of participants who achieved SVR for the overall sample and for those with complete data (N=1029) were 86.2% (95% CI 84.08-88.19%) and 94.3% (95% CI 92.8-95.7%) respectively. The analysis of data restricted to only those with SVR data available showed that PWID who were currently injecting had comparable SVR rates (89.2%, 95% CI 81.5-94.5%) to PWID not injecting (94.4%, 95% CI 92.4-96.1), PWID on methadone (94.4%, 95%CI 92.4-96.1), and 'other' risk groups (95.2%, 95% CI 91.3-97.7). Independent factors associated with achieving a SVR were female sex (AOR: 3.44, 95% CI 1.45-8.14), HCV genotype 3 (AOR: 4.57, 95% CI 1.97-10.59) compared to genotype 1. SVR rates in PWID actively injecting did not differ significantly from any other group.

CONCLUSION

Both patient-level and structural factors influence HCV treatment scale-up in Ukraine, but patient-level outcomes confirm high levels of achieving SVR in PWID, irrespective of injection and treatment status.

Improvements in brain and behavior following eradication of hepatitis C

Despite recent advances in treatment, hepatitis C remains a significant public health problem. The hepatitis C virus (HCV) is known to infiltrate the brain, yet findings from studies on associated neurocognitive and neuropathological changes are mixed. Furthermore, it remains unclear if HCV eradication improves HCV-associated neurological compromise. This study examined the longitudinal relationship between neurocognitive and neurophysiologic markers among healthy HCV- controls and HCV+ adults following successful HCV eradication. We hypothesized that neurocognitive outcomes following treatment would be related to both improved cognition and white matter integrity. Participants included 57 HCV+ participants who successfully cleared the virus at the end of treatment (sustained virologic responders [SVRs]) and 22 HCV- controls. Participants underwent neuropsychological testing and, for a nested subset of participants, neuroimaging (diffusion tensor imaging) at baseline and 12 weeks following completion of HCV therapy. Contrary to expectation, group-level longitudinal analyses did not reveal significant improvement in neurocognitive performance in the SVRs compared to the control group. However, a subgroup of SVRs demonstrated a significant improvement in cognition relative to controls, which was related to improved white matter integrity. Indeed, neuroimaging data revealed beneficial effects associated with clearing the virus, particularly in the posterior corona radiata and the superior longitudinal fasciculus. Findings suggest that a subgroup of HCV+ patients experienced improvements in cognitive functioning following eradication of HCV, which appears related to positive changes in white matter integrity. Future research should examine whether any additional improvements in neurocognition and white matter integrity among SVRs occur with longer follow-up periods.

Nonprescription naloxone and syringe sales in the midst of opioid overdose and hepatitis C virus epidemics: Massachusetts, 2015

OBJECTIVES

To determine the prevalence of nonprescription naloxone and sterile syringe sales, factors associated with nonprescription sales, geospatial access to nonprescription naloxone and syringe-selling pharmacies, and targets for potential interventions.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

Massachusetts has experienced steep increases in reported opioid overdoses and hepatitis C virus cases in the past decade. Pharmacists have the potential to play a substantial role in increasing access to nonprescription naloxone and sterile syringes, which can reverse opioid overdoses and decrease hepatitis C virus transmission, respectively. We completed brief telephone surveys with 809 of 1042 retail pharmacies across Massachusetts (response rate = 77.6%) during 2015 to assess experience with nonprescription sales of naloxone and sterile syringes.

OUTCOME MEASURES

Our primary outcomes were the stocking and selling of naloxone in the pharmacy (yes or no) for nonprescription sales and nonprescription syringe sales (yes or no). We conducted multivariable regression analyses and created maps using a geographic information system to identify factors associated with nonprescription sales of naloxone and sterile syringes, and to improve our understanding of geospatial access to pharmacy-based naloxone and syringe sales.

RESULTS

More than 97% of pharmacies reported selling sterile syringes without requiring a prescription, and 45% of pharmacies reported stocking and selling naloxone. Factors associated with nonprescription sales included hours of operation, experience with and interest in harm reduction activities, and presence in an opioid overdose hotspot. Geographic access to nonprescription sale of sterile syringes is widespread, whereas geospatial access to naloxone is limited. Training to understand the benefits, applications, and distribution needs of naloxone is of interest to surveyed pharmacists.

CONCLUSION

Access to sterile syringes through nonprescription sales is strong across Massachusetts, and although more than 350 pharmacies (45%) reported stocking and selling naloxone to prevent opioid overdose deaths, there is much room for improvement in access and training among pharmacy staff members.

The lived experience of interferon-free treatments for hepatitis C: A thematic analysis

BACKGROUND

International discourse concerning the evolution in hepatitis C virus (HCV) therapy has tended to focus on improving outcomes, shortened treatment length and reduced side-effects of interferon-free regimens. How these treatments are being understood and experienced by the people receiving them has so far been overlooked. This study therefore aimed to explore the lived experience of individuals taking interferon-free HCV therapies.

METHODS

Data were generated through 16 semi-structured interviews with a purposive sample of eight participants, recruited from a university hospital in Scotland. The interviews took place between June 2015 and March 2016, before and after a period of interferon-free HCV treatment. The data were interrogated using a thematic analysis, underpinned by social phenomenological theory.

RESULTS

Three overriding themes were identified. 'Expectations and realisations' characterised the influence that interferon continued to cast over interferon-free treatment, contrasting the practicalities of taking interferon-free therapy with preconceived notions. 'An honour and a pleasure' portrayed a positive experience of an undemanding therapy, yet among those with a history of drug use, was also positioned as a privilege, associated with feelings of luck and guilt. 'Treatment needs' illustrated the strategies participants used to search for treatment efficacy, and the value those with a significant history of drug use placed on support. One nonconforming case is then discussed to enhance rigour and trustworthiness.

CONCLUSION

This is the first qualitative exploration of the experience of interferon-free HCV treatment reported globally. The results from this study suggest a cultural lag exists between the pharmacological developments which have been witnessed, and societal understandings of them. This has implications for the way services meet the needs of, and offer therapy to, HCV positive individuals.

Facilitators of HCV treatment adherence among people who inject drugs: a systematic qualitative review and implications for scale up of direct acting antivirals

Background

While the public health benefits of new HCV treatments depend on treatment adherence, particularly among people who inject drugs (PWID), several social and medical factors can jeopardize treatment adherence. The aim of this study is to examine the qualitative literature on facilitators to HCV treatment adherence among PWID.

Methods

We searched six databases to identify qualitative research studies on HCV treatment adherence facilitators among PWID. Two reviewers independently extracted and analyzed data using PRISMA guidelines and the CASP tool to evaluate study quality.

Results

From ten studies representing data from 525 participants, three major themes emerged across studies: logistical facilitators within health systems enhanced HCV treatment adherence, positive social interactions between PWID and staff provided positive feedback during treatment, and HCV treatment may complicate the addiction recovery process.

Conclusions

Although PWID face several barriers to adherence, we identified treatment adherence facilitators that could be incorporated into clinical practice.

Public health and international drug policy

In September 2015, the member states of the United Nations endorsed sustainable development goals (SDG) for 2030 that aspire to human rights-centered approaches to ensuring the health and well-being of all people. The SDGs embody both the UN Charter values of rights and justice for all and the responsibility of states to rely on the best scientific evidence as they seek to better humankind. In April 2016, these same states will consider control of illicit drugs, an area of social policy that has been fraught with controversy, seen as inconsistent with human rights norms, and for which scientific evidence and public health approaches have arguably played too limited a role.

The previous UN General Assembly Special Session (UNGASS) on drugs in 1998 – convened under the theme “a drug-free world, we can do it!” – endorsed drug control policies based on the goal of prohibiting all use, possession, production, and trafficking of illicit drugs. This goal is enshrined in national law in many countries. In pronouncing drugs a “grave threat to the health and well-being of all mankind,” the 1998 UNGASS echoed the foundational 1961 convention of the international drug control regime, which justified eliminating the “evil” of drugs in the name of “the health and welfare of mankind.” But neither of these international agreements refers to the ways in which pursuing drug prohibition itself might affect public health. The “war on drugs” and “zero-tolerance” policies that grew out of the prohibitionist consensus are now being challenged on multiple fronts, including their health, human rights, and development impact.

The Johns Hopkins – Lancet Commission on Drug Policy and Health has sought to examine the emerging scientific evidence on public health issues arising from drug control policy and to inform and encourage a central focus on public health evidence and outcomes in drug policy debates, such as the important deliberations of the 2016 UNGASS on drugs.

The Johns Hopkins-Lancet Commission is concerned that drug policies are often colored by ideas about drug use and drug dependence that are not scientifically grounded. The 1998 UNGASS declaration, for example, like the UN drug conventions and many national drug laws, does not distinguish between drug use and drug abuse. A 2015 report by the UN High Commissioner for Human Rights, by contrast, found it important to emphasize that “[d]rug use is neither a medical condition nor does it necessarily lead to drug dependence.” The idea that all drug use is dangerous and evil has led to enforcement-heavy policies and has made it difficult to see potentially dangerous drugs in the same light as potentially dangerous foods, tobacco, alcohol for which the goal of social policy is to reduce potential harms.

The promise of treatment as prevention for hepatitis C: Meeting the needs of people who inject drugs?

Treatment as prevention (TasP) is a concept common to the HIV sector. In this commentary we draw on the literature addressing HIV and HCV TasP, alongside qualitative HCV research, to critically appraise the promise of TasP for HCV and assess the needs of PWID in the future of HCV care. With the advent of highly effective direct-acting antiviral HCV treatments, TasP is now under consideration for HCV. A growing body of literature documents numerous social structural barriers to HCV treatment access and uptake for PWID, among whom HCV is highly prevalent. Yet these barriers - and suggestions for surmounting them - are rarely included in emergent literature on HCV TasP. Although HCV TasP has important advocacy potential for increasing treatment access among PWID, critical reflection on its implications are warranted. We outline potential limitations of TasP for HCV and the conditions under which it might be optimised. We argue that HCV treatment as a prevention strategy can only be realisable in a context of enhanced harm reduction access, meaningful community engagement, and enabling environment interventions informed by the needs and perspectives of PWID.
