HCV microelimination strategies: An interventional study in diagnosed patients without access to the system.

Hepatitis C virus (HCV) one-step diagnosis improves recovery in patients with active infection. However, patients with previous anti-HCV+ may be excluded. We aimed to identify and retrieve non-referred or lost-to-follow-up HCV-infected patients. All anti-HCV+ patients seen in our hospital between 2013 and 2018 were included. In the first phase, we identified anti-HCV+ patients who were not referred to the Gastroenterology Unit (GU) or lost-to-follow-up. In the second phase, recovered patients were invited for a one-step visit for liver evaluation. A total of 1330 anti-HCV+ patients were included: 21.7% had not been referred to GU, and 23.1% were lost-to-follow-up. In the second phase, 49.6% of patients were contacted, and 92.8% attended a medical consultation: 62.7% had active infection, 92.2% were treated, and 86.5% achieved SVR (ITT). We concluded that screening microbiological data and referring unidentified patients with active HCV infection directly to specialists is an effective tool in achieving HCV microelimination.

The impact of unrestricted access to direct-acting antiviral among incarcerated hepatitis C virus-infected patients.

Background/AimsDespite the disproportionally high prevalence rates of hepatitis C virus (HCV) amongst the incarcerated population, eradication remains challenging due to logistic and financial barriers. Although treatment prioritization based on disease severity is commonly practiced, the efficacy of such approach remained uncertain. We aimed to compare the impact of unrestricted access to direct-acting antiviral (DAA) among incarcerated HCV-infected patients in Singapore.MethodsIn this retrospective study, we reviewed all incarcerated HCV-infected patients treated in our hospital during the restricted DAA era (2013–2018) and unrestricted DAA access era (2019). Study outcomes included the rate of sustained virological response (SVR), treatment completion and treatment default. Subgroup analysis was performed based on the presence of liver cirrhosis, HCV genotype and HCV treatment types.ResultsA total of 1,001 HCV patients was followed-up for 1,489 person-year. They were predominantly male (93%) with genotype-3 HCV infection (71%), and 38% were cirrhotic. The overall SVR during the restricted DAA access era and unrestricted DAA access era were 92.1% and 99.1%, respectively. Unrestricted access to DAA exponentially improved the treatment access among HCV-infected patients by 460%, resulting in a higher SVR rate (99% vs. 92%, P=0.003), higher treatment completion rate (99% vs. 93%, P<0.001) and lower treatment default rate (1% vs. 9%, P<0.001).Conclusion: In this large cohort of incarcerated HCV-infected patients, we demonstrated that unrestricted access to DAA is an impactful strategy to allow rapid treatment up-scale in HCV micro-elimination.

HCV micro-elimination in individuals with HIV in the Netherlands 4 years after universal access to direct-acting antivirals: a retrospective cohort study

In the Netherlands, access to direct-acting antivirals (DAAs) against hepatitis C virus (HCV) has been unrestricted for chronic infection since 2015. We evaluated whether the nationwide incidence of HCV infections in individuals with HIV has changed since 2015. In this retrospective cohort study, data from the ATHENA cohort of people with HIV aged 18 years or older attending any of the 24 HIV treatment centres in the Netherlands between 2000 and 2019 were assessed. We used parametric proportional hazards models with a piecewise exponential survival function to model HCV primary infection and reinfection incidence per 1000 person-years. Of the 23 590 individuals without previous HCV infection, 1269 cases of HCV primary infection were documented (incidence 5·2 per 1000 person-years [95% CI 5·0-5·5]). The highest incidence was observed in men who have sex with men (MSM; 7·7 per 1000 person-years [7·3-8·2]) and was lower in people who inject drugs (PWID; 1·7 per 1000 person-years [0·7-4·1]) and other key populations (1·0 per 1000 person-years [0·8-1·2]). In MSM, incidence increased in 2007 to 14·3 per 1000 person-years and fluctuated between 8·7 and 13·0 per 1000 person-years from 2008 to 2015. In 2016, incidence declined to 6·1 cases per 1000 person-years and remained steady between 4·1 and 4·9 per 1000 person-years from 2017 to 2019. Of the 1866 individuals with a previous HCV infection, 274 reinfections were documented (incidence 26·9 per 1000 person-years [95% CI 23·9-30·3]). The highest incidence rate was observed in MSM (38·5 per 1000 person-years [33·9-43·7]) and was lower in PWID (10·9 per 1000 person-years [3·5-33·8]) and other key populations (8·9 per 1000 person-years [6·3-12·5]). In MSM, reinfection incidence fluctuated between 38·0 and 88·9 per 1000 person-years from 2006 to 2015, reaching 55·6 per 1000 person-years in 2015. In 2016, reinfection incidence declined to 41·4 per 1000 person-years, followed by further decreases to 24·4 per 1000 person-years in 2017 and 11·4 per 1000 person-years in 2019. The sharp decline in HCV incidence in MSM with HIV shortly after restrictions on DAAs were lifted suggests a treatment-as-prevention effect. HCV incidence was already low in PWID and other groups before unrestricted access. Ongoing HCV transmission is occurring in MSM, as illustrated by a declining but high rate of reinfection, stressing the need for additional preventive measures.

Increased case-finding and uptake of direct-acting antiviral treatment essential for micro-elimination of hepatitis C among people living with HIV: a national record linkage study.

Micro-elimination of hepatitis C virus (HCV) in people living with HIV (PLHIV) and co-infected with HCV has been proposed as a key contribution to the overall goal of HCV elimination. While other studies have examined micro-elimination in HIV-treated cohorts, few have considered HCV micro-elimination among those not treated for HIV or at a national level. Through data linkage of national and sentinel surveillance data, we examined the extent of HCV testing, diagnosis and treatment among a cohort of PLHIV in Scotland identified through the national database of HIV-diagnosed individuals, up to the end of 2017. Of 5018 PLHIV, an estimated 797 (15%) had never been tested for HCV and 70 (9%) of these had undiagnosed chronic HCV. The odds of never having been tested for HCV were the highest in those not on HIV treatment [adjusted odds ratio (aOR)=7.21, 95% confidence interval (CI): 5.15-10.10). Overall HCV antibody positivity was 11%, and it was at its highest among people who inject drugs (49%). Most of those with chronic HCV (91%) had attended an HCV treatment clinic but only half had been successfully treated (54% for those on HIV treatment, 12% for those not) by the end of 2017. The odds of never having been treated for HCV were the highest in those not on HIV treatment (aOR=3.60, 95% CI: 1.59-8.15). Our data demonstrate that micro-elimination of HCV in PLHIV is achievable but progress will require increased effort to engage and treat those co-infected, including those not being treated for their HIV.

What is needed to achieve HCV microelimination among HIV-infected populations in Andalusia, Spain: a modeling analysis

BackgroundScale-up of hepatitis C virus (HCV) treatment for HIV/HCV coinfected individuals is occurring in Spain, the vast majority (> 85%) with a reported history of injecting drug use and a smaller population of co-infected men who have sex with men (MSM). We assess impact of recent treatment scale-up to people living with HIV (PLWH) and implications for achieving the WHO HCV incidence elimination target (80% reduction 2015–2030) among PLWH and overall in Andalusia, Spain, using dynamic modeling.MethodsA dynamic transmission model of HCV/HIV coinfection was developed. The model was stratified by people who inject drugs (PWID) and MSM. The PWID component included dynamic HCV transmission from the HCV-monoinfected population. The model was calibrated to Andalusia based on published data and the HERACLES cohort (prospective cohort of HIV/HCV coinfected individuals representing > 99% coinfected individuals in care in Andalusia). From HERACLES, we incorporated HCV treatment among diagnosed PLWH of 10.5%/year from 2004 to 2014, and DAAs at 33%/year from 2015 with 94.8% SVR. We project the impact of current and scaled-up HCV treatment for PLWH on HCV prevalence and incidence among PLWH and overall.ResultsCurrent treatment rates among PLWH (scaled-up since 2015) could substantially reduce the number of diagnosed coinfected individuals (mean 76% relative reduction from 2015 to 2030), but have little impact on new diagnosed coinfections (12% relative reduction). However, DAA scale-up to PWLH in 2015 would have minimal future impact on new diagnosed coinfections (mean 9% relative decrease from 2015 to 2030). Similarly, new cases of HCV would only reduce by a mean relative 29% among all PWID and MSM due to ongoing infection/reinfection. Diagnosing/treating all PLWH annually from 2020 would increase the number of new HCV infections among PWLH by 28% and reduce the number of new HCV infections by 39% among the broader population by 2030.ConclusionTargeted scale-up of HCV treatment to PLWH can dramatically reduce prevalence among this group but will likely have little impact on the annual number of newly diagnosed HIV/HCV coinfections. HCV microelimination efforts among PWLH in Andalusia and settings where a large proportion of PLWH have a history of injecting drug use will require scaled-up HCV diagnosis and treatment among PLWH and the broader population at risk.

A Treatment-as-Prevention Trial to Eliminate Hepatitis C Among Men Who Have Sex With Men Living With Human Immunodeficiency Virus (HIV) in the Swiss HIV Cohort Study.

In 2016, the World Health Organization (WHO) introduced global targets for the elimination of hepatitis C virus (HCV) by 2030. We conducted a nationwide HCV micro-elimination program among men who have sex with men (MSM) living with human immunodeficiency virus (HIV) from the Swiss HIV Cohort Study (SHCS) to test whether the WHO goals are achievable in this population. During phase A (10/2015-06/2016), we performed a population-based and systematic screening for HCV-RNA among MSM from the SHCS. During phase B (06/2016-02/2017) we offered treatment with HCV direct-acting antiviral (DAA) agents to MSM identified with a replicating HCV infection. During phase C (03/2017-11/2017), we offered rescreening to all MSM for HCV-RNA and initiated DAA treatment in MSM with replicating infections. We screened 3715/4640 (80%) MSM and identified 177 with replicating HCV infections (4.8%); 150 (85%) of whom started DAA treatment and 149 (99.3%) were cured. We rescreened 2930/3538 (83%) MSM with a prior negative HCV-RNA and identified 13 (0.4%) with a new HCV infection. At the end of the micro-elimination program, 176/190 MSM (93%) were cured, and the HCV incidence rate declined from .53 per 100 patient-years (95% CI, .35-.83) prior to the intervention to .12 (95% CI, .03-.49) by the end of 2019. A systematic, population-based HCV micro-elimination program among MSM living with HIV was feasible and resulted in a strong decline in HCV incidence and prevalence. Our study can serve as a model for other countries aiming to achieve the WHO HCV elimination targets. NCT02785666.

Hépatite C en milieu psychiatrique : un réservoir oublié ?

Hepatitis C is a transmissible hepatic and extra-hepatic disease caused by the hepatitis C virus (HCV). HCV develops into a chronic infection among approximately 70% of the contaminated subjects. Chronic HCV infection is estimated to affect between 0.5% and 1 % of the general population in France, which causes an important burden of disease, in particular due to the occurrence of cirrhosis and liver cancer. New antiviral drugs now allow to cure more than 95% of patients in just a few weeks of treatment with very limited safety issues. This therapeutic revolution has led the World Health Organization and many national governments to aim for an elimination of HCV, which has been defined as a 90%-reduction of the incidence rate, and a 65%-reduction in the number of HCV-related deaths on the basis of the 2015 figures. In this respect, the French Ministry of Health has recently decided to extend the ability to prescribe the new antiviral drugs to any physician. However, the elimination campaign of HCV will also need to correctly identify, screen, and treat the main target populations. If people who inject drugs (PWIDs) certainly constitute the most important population concerned by the challenge of HCV elimination, more hidden reservoirs in which HCV transmission can insidiously evolve should be identified and specifically targeted as well. Inpatient psychiatric populations might constitute one of these hidden reservoirs. International data suggest that chronic HCV infection affects approximately 5% of psychiatric inpatients in Europe. This very high prevalence estimate can in part be due to the very frequent psychiatric disorders found among the current or former PWIDs. However, a part of the seropositive patients does not report a history of drug use, and other factors could contribute to the increased risk of contamination in this population including atypical routes of transmission related to institutional promiscuity. Exploring the general profile and risk-behaviors of the psychiatric inpatients found infected by the HCV is thus warranted for future studies. Screening and treating HCV in the specific population of psychiatric patients is part of the general public health objective of eliminating HCV at a national level. Moreover, it also directly fits into the individualized psychiatric care. Many recent data suggest that HCV also has a neural tropism, in particular within glial cells, such as astrocytes or oligodendrocytes. As such, HCV foments inflammatory processes in the brain and contributes to cognitive impairments and psychiatric symptoms such as anxiety or depression. At the individual level, treating HCV infection can improve the psychiatric state and increase patients’ outcomes in terms of well-being and quality of life. For all these reasons, the field of psychiatry needs local and national actions for informing and training professionals about HCV screening and treating modalities. Patient and family associations also need to be involved in this general effort of micro-elimination. A key role should be assigned to the general practitioners embedded within inpatient psychiatric units. They are the best fitted professionals to screen, treat, and empower patients, to inform and train other caregivers of the psychiatric field, and to act as a relay with hepatology teams if required. Hospital pharmacists are other important stakeholders. In a national context in which the funding of psychiatric care, including medications, is based on predefined funding envelops, innovative initiatives will have to be set up by local or national health authorities, in partnership with pharmacists, to allow for the treatment of psychiatric inpatients. In conclusion, the world of psychiatry is a possible hidden reservoir of HCV and, as such, a part of the challenge for eliminating the virus. Patients, families, and caregivers will have to be correctly sensitized and trained to play their role in the process. Specific investigations will be required to better understand why such an increased prevalence of HCV is observed in this population. Specific adaptations of the cascade of care within psychiatric settings, including access to treatment, will need to be designed, implemented, and evaluated for reaching micro-elimination of HCV in psychiatry.

Prevalence of Hepatitis C Virus in an Endemic Area of Thailand: Burden Assessment toward HCV Elimination.

Chronic hepatitis C virus (HCV) infection can lead to liver cirrhosis and hepatocellular carcinoma. To eliminate HCV infection in an endemic area, an epidemiological baseline of the current HCV infection in the population is required. We therefore aimed to evaluate the HCV burden in the Thai Province of Phetchabun, which has the highest HCV infection rate in the country. Toward this, a province-wide district-based representative sampling of 4,769 individuals ages 35-64 years previously shown to represent high-risk age-groups were tested for anti-HCV antibodies using the automated chemiluminescent microparticle assays. Active HCV infection and subsequent genotyping were determined from serologically reactive samples by amplification of the HCV core gene. We found that 6.9% (327/4,769) were anti-HCV positive, of which 75.8% (248/327) had detectable HCV RNA and 5.8% (19/327) were in the presence of hepatitis B virus coinfection. Nucleotide sequencing and phylogenetic analysis revealed that HCV genotype 6 was the most prevalent (41%, 101/248), followed by genotype 3 (31%, 78/248), and genotype 1 (28%, 69/248). Socioeconomic and demographic factors including male gender, education, and agricultural work were associated with HCV seropositivity. From these results, we defined the regional HCV genotypes and estimated the HCV burden necessary toward the implementation of pan-genotypic direct-acting antivirals, which may be appropriate and effective toward the diversity of genotypes identified in this study. Micro-elimination of HCV in Phetchabun may serve as a model for a more comprehensive coverage of HCV treatment in Thailand.

The role of prison-based interventions for hepatitis C virus (HCV) micro-elimination among people who inject drugs in Montréal, Canada

BackgroundIn Canada, hepatitis C virus (HCV) transmission primarily occurs among people who inject drugs (PWID) and people with experience in the prison system bare a disproportionate disease burden. These overlapping groups of individuals have been identified as priority populations for HCV micro-elimination in Canada, which is currently not on track to achieve its elimination targets. Considering the missed opportunities to intervene in provincial prisons, this study aims to estimate the population-level impact of prison-based interventions and post-release risk reduction strategies on HCV transmission among PWID in Montréal, a Canadian city with high HCV burden. MethodsA dynamic HCV transmission model among PWID was developed and calibrated to community and prison bio-behavioural surveys in Montréal. Then, the relative impact of prison-based testing and treatment or post-release linkage to care (both 90% testing and 75% treatment coverage), alone or in combination with strategies that reduce the heightened post-release transmission risk by 50%, was estimated from 2018 to 2030, and compared to counterfactual scenarios. ResultsPrison-based test-and-treat strategies could lead to the greatest declines in incidence (48%; 95%CrI: 38–57%) over 2018–2030 and prevent the most new first chronic infections (22%; 95%CrI: 16−28%) among people never exposed to HCV. Prison testing and post-release linkage to care lead to a slightly lower decrease in incidence and prevented fraction of new chronic infections. Combining test-and-treat with risk reduction measures could further its epidemiological impact, preventing 35% (95%CrI: 29−40%) of new first chronic infections. When implemented concomitantly with community-based treatment scale-up, prison-based interventions had synergistic effects, averting a higher fraction of new first chronic infections. ConclusionOffering HCV testing and treatment in provincial prisons, where incarcerations are frequent and sentences short, could change the course of the HCV epidemic in Montréal. Prison-based interventions with potential integration of post-release risk reduction measures should be considered as an integral part of HCV micro-elimination strategies in this setting.

Decline in Hepatitis C Virus (HCV) Incidence in Men Who Have Sex With Men Living With Human Immunodeficiency Virus: Progress to HCV Microelimination in the United Kingdom?

BackgroundModeling of the London hepatitis C virus (HCV) epidemic in men who have sex with men (MSM) and are living with human immunodeficiency virus (HIV) suggested that early access to direct-acting antiviral (DAA) treatment may reduce incidence. With high rates of linkage to care, microelimination of HCV within MSM living with HIV may be realistic ahead of 2030 World Health Organization targets. We examined trends in HCV incidence in the pre- and post-DAA eras for MSM living with HIV in London and Brighton, United Kingdom.MethodsA retrospective cohort study was conducted at 5 HIV clinics in London and Brighton between 2013 and 2018. Each site reported all acute HCV episodes during the study period. Treatment timing data were collected. Incidence rates and reinfection proportion were calculated.ResultsA total of378 acute HCV infections were identified, comprising 292 first infections and 86 reinfections. Incidence rates of acute HCV in MSM living with HIV peaked at 14.57/1000 person-years of follow-up (PYFU; 95% confidence interval [CI], 10.95–18.20) in 2015. Rates fell to 4.63/1000 PYFU (95% CI, 2.60 to 6.67) by 2018. Time from diagnosis to starting treatment declined from 29.8 (2013) to 3.7 months (2018).ConclusionsWe observed a 78% reduction in the incidence of first HCV episode and a 68% reduction in overall HCV incidence since the epidemic peak in 2015, which coincides with wider access to DAAs in England. Further interventions to reduce transmission, including earlier access to treatment and for reinfection, are likely needed for microelimination to be achieved in this population.

Interventions to reduce acute hepatitis C virus in HIV-positive MSM.

The WHO has set ambitious targets for hepatitis C virus (HCV) elimination by 2030. In this review, we explore the possibility of HCV micro-elimination in HIV-positive (+) MSM, discussing strategies for reducing acute HCV incidence and the likely interventions required to meet these targets. With wider availability of directly acting antivirals (DAAs) in recent years, reductions in acute HCV incidence have been reported in some cohorts of HIV+ MSM. Recent evidence demonstrates that treatment in early infection is well tolerated, cost effective and may reduce the risk of onward transmission. Modelling studies suggest that to reduce incidence, a combination approach including behavioural interventions and access to early treatment, targeting both HIV+ and negative high-risk groups, will be required. HCV vaccine trials have not yet demonstrated efficacy in human studies, however phase one and two studies are ongoing. Some progress towards the WHO HCV elimination targets has been reported. Achieving sustained HCV elimination is likely to require a combination approach including early access to DAAs in acute infection and reinfection, validated and reproducible behavioural interventions and an efficacious HCV vaccine.

A Path to Ending Hepatitis C in Ethiopia: A Phased Public Health Approach to Achieve Micro-Elimination.

Ethiopia's hepatitis C virus (HCV) prevalence is predicted to rise by 2030. To halt this increasing trend, a suitable approach to the elimination of HCV is needed. This review explores the current status, challenges, and opportunities and outlines a strategy for the micro-elimination approach in Ethiopia. I searched PubMed and EMBASE using combined Medical Subject Heading databases for the literature on HCV micro-elimination. A phased public health approach to HCV micro-elimination, including preparation/capacity building (phase I), implementation (phase II), and rollout and scale-up (phase III), targeting people living with HIV, prisoners, chronic hepatitis and cancer patients, blood donors, and pregnant women is a pragmatic strategy to Ethiopia. This can be implemented at general and tertiary care referral hospitals with a future scale-up to district hospitals through task-shifting by training general practitioners, nurses, laboratory technologists, and pharmacists. Availability of the highly effective direct-acting antivirals (DAAs) can be ensured by expanding the existing program that provides highly subsidized DAAs through an agreement with Gilead Sciences, Inc. and eventually aiming at domestic generic manufacturing. The significant enablers to HCV micro-elimination in Ethiopia include the control of healthcare-associated HCV infection, blood safety, access to affordable testing and pan-genotypic DAAs, task-shifting, multisectoral partnership, and regulatory support. General population-based HCV screening and treatment are not cost-effective for Ethiopia because of high cost, program complexity, and disease epidemiology.

298. Collocation of Hepatitis C Care Continuum with MAT for High-Prevalence, High-Risk Population

BackgroundThe hepatitis C virus (HCV) epidemic in the United States disproportionately impacts people who inject drugs (PWID) who account for 80% of new infections and have a high prevalence of chronic infection. Baltimore City has the highest case rate of HCV in the state of Maryland with over 25% of new cases statewide occurring in the city. Only 10% of PWID have access to directly acting antiviral (DAA) therapy and are cured of HCV. Medication-assisted treatment (MAT) is currently offered in isolated facilities with limited access to other specialty care. In this study, we collocated HCV care continuum in a MAT facility offering opioid agonist therapy and psychosocial interventionsMethodsCollocation of HCV care was initiated in an MAT (methadone and buprenorphine) clinic, the University of Maryland Drug Treatment Center (UMDTC) serving over 700 patients, for Opioid Use Disorder (OUD) in Baltimore City (Figure 1). Screening for HCV was expanded through health education of patients and staff and expanded testing. HCV antibody-positive patients were linked to care with an experienced HCV provider or referred to hepatologists (decompensated cirrhosis).ResultsMost of the attendees were African-American with an average age of 52 years. 354 out of 701 clients attending clinic for methadone/suboxone (50.5%) were screened for HCV. Of the 251 patients who were hepatitis C antibody positive (70% of tested), 54 had undetectable HCV RNA. 46 had no HCV RNA labs available. 151 of the remaining HCV Ab positive patients who had a detectable HCV RNA result were evaluated for treatment (Figure 2). At initial assessment, 45 (48%) with liver fibrosis staged greater than F3, including 25 (27%) with cirrhosis. Sixty-four patients initiated DAA therapy. Fifty-four patients completed treatment (84%). Forty patients achieved sustained virologic response (100%) and 14 patients who completed treatment await SVR labs.ConclusionCollocation of HCV care continuum in MAT setting is an effective way to achieve micro elimination of HCV. The follow-up of this marginalized population still remains challenging given the high rates of homelessness and incarceration. In this regard, coordinated care between MAT settings and prisons are likely to demonstrate successful elimination of hepatitis C. Disclosures All authors: No reported disclosures.

The HIPPOCRATES Project: A Proof of Concept Promoting HCV Microelimination Strategy Plan in Prisons

Background & Aims: In the last few years we have witnessed a revolution in the treatment of hepatitis C virus (HCV) infection. With the introduction of direct-acting antiviral agents (DAA), sustained virological response (SVR) is achieved in more than 95% of the patients. The focus is now being turned on to high-risk groups, with the aim of achieving HCV elimination by 2030. Prison inmates constitute one of the high-risk groups, and they receive treatment less frequently due to barriers in access to health care. The aim of this study is to describe the management and follow-up of a cohort of HCV monoinfected patients treated with DAA in the prison setting. Methods: A prospective observational study was performed including all prison inmates monoinfected with HCV, from April 2017 to March 2018 in a Portuguese prison. Demographic, clinical and laboratorial data, as well as transient elastography measurements, were collected onsite by the medical team and prospectively recorded. Patients were treated with DAA according to international guidelines. SVR rates and adverse events were analyzed. Results: 67 monoinfected HCV male inmates (mean age of 42,4 ±8,1 years) were enrolled. 72% reported history of injecting drugs or tattooing, with 44% of the latter being made in prison. 78% referred alcohol consumption of more than 30 g/day. The most prevalent genotype was 1a (54%), followed by 3 (30%) 4 (9%) and 1b (8%). Pretreatment fibrosis degree was mild-to-moderate (F0-F2) in 78% and severe in 22% (F3-F4). Treatment regimens chosen were: 52% elbasvir/grazoprevir, 30% sofosbuvir/velpatasvir and 18% sofosbuvir/ledispavir. No major adverse events were observed. SVR rate was 100%. Conclusions: In a population considered hard-to-access and a cornerstone for HCV elimination, the doctors' visits to the prison setting, as well as the assisted medication administration lead to a 100% rate of SVR.
