Abstract
Introduction: The effective and persistent suppression of hepatitis B surface antigen (HBsAg) in patients with chronic HBV infection (CHB) is considered to be a promising approach to achieve a functional cure of hepatitis B. In our previous study, we found that the antibody E6F6 can clear HBsAg through FcγR-mediated phagocytosis, and its humanized form (huE6F6 antibody) is expected to be a new tool for the treatment of CHB. Previous studies have shown that the glycosylation of Fc segments affects the binding of antibodies to FcγR and thus affects the biological activity of antibodies in vivo. Methods: To further improve the therapeutic potential of huE6F6, in this study, we defucosylated huE6F6 (huE6F6-fuc-), preliminarily explored the developability of this molecule, and studied the therapeutic potential of this molecule and its underlying mechanism in vitro and in vivo models. Results: huE6F6-fuc- has desirable physicochemical properties. Compared with huE6F6-wt, huE6F6-fuc- administration resulted in a stronger viral clearance in vivo. Meanwhile, huE6F6-fuc- keep a similar neutralization activity and binding activity to huE6F6-wt in vitro. Immunological analyses suggested that huE6F6-fuc- exhibited enhanced binding to hCD32b and hCD16b, which mainly contributed to its enhanced therapeutic activity in vivo. Conclusions: In summary, the huE6F6-fuc- molecule that was developed in this study, which has desirable developability, can clear HBsAg more efficiently in vivo, providing a promising treatment for CHB patients. Our study provides new guidance for antibody engineering in other disease fields.

Abstract
INTRODUCTION Evaluating progress towards hepatitis C virus (HCV) elimination among Aboriginal and Torres Strait Islander peoples is critical given the disproportionate burden of infection. We examined factors associated with current HCV infection and self-reported treatment among Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal peoples) and non-Aboriginal peoples who inject drugs (PWID) in Australia. METHODS ETHOS Engage is an observational cohort study of PWID attending drug treatment and needle and syringe programs in Australia. Participants underwent point-of-care HCV RNA testing (Xpert HCV RNA Viral Load Fingerstick) and completed a questionnaire including self-reported history of HCV treatment. RESULTS Between May 2018 and June 2021, 2395 participants were enrolled and 555 (23%) identified as Aboriginal (median age 42 years, 58% were men, 63% injected drugs in last month, 76% ever incarcerated). HCV RNA prevalence was 23% among Aboriginal PWID (24% in 2018-2019 and 21% in 2019-2021; p = 0.44), and 21% among non-Aboriginal PWID (24% in 2018-2019 and 16% in 2019-2021; p < 0.001). Self-reported HCV treatment was 65% among Aboriginal PWID (63% in 2018-2019 and 69% in 2019-2021; p = 0.30), and 70% among non-Aboriginal PWID (67% in 2018-2019 and 75% in 2019-2021; p < 0.001). Among Aboriginal PWID, current HCV infection was associated with recently injecting drugs and receiving opioid agonist treatment, and self-reported HCV treatment was negatively associated with younger age, homelessness and recently injecting drugs. DISCUSSION AND CONCLUSIONS Equitable access to HCV care and prevention is needed to ensure Australia meets its elimination targets among Aboriginal PWID.

Abstract
Hepatitis C virus (HCV) infection causes a substantial economic burden, not only in terms of healthcare costs, but also in labour productivity losses. The main objective of this study is to provide objective and comparable information about the trend in labour productivity losses caused by premature HCV-associated deaths in Spain in recent years (2009-2018). We used nationwide data from several official sources to create a simulation model based on the human capital approach and to estimate the flows in labour productivity losses due to deaths identified in the period considered. Based on a pessimistic scenario, the annual number of deaths due to HCV infections decreased by 19.7% between 2009 and 2018. The years of potential labour productive life lost (YPLPLL) decreased by 38.1%. That reduction led to a decrease in annual labour productivity losses from €236 million in 2009 to €156 million in 2018 (-33.8%). The aggregate HCV-related labour productivity losses between 2009 and 2018 ranged from €1742 million (optimistic scenario) to €1949 million (pessimistic scenario), with an intermediate estimation of €1846 million (moderately optimistic scenario). These results show a substantial reduction in annual deaths, working-age deaths, YPLPLL, and labour productivity losses associated with HCV infection over this period.

Abstract
OBJECTIVE Reinfection poses a challenge to hepatitis C virus (HCV) elimination. This analysis assessed incidence of, and factors associated with reinfection among people treated for recent HCV (duration of infection <12 months). METHODS Participants treated for recent HCV (primary infection or reinfection) in an international randomized trial were followed at 3-monthly intervals for up to 2 years to assess for reinfection. Reinfection incidence was calculated using person-time of observation. Factors associated with HCV reinfection were assessed using Cox proportional hazards regression analysis. RESULTS Of 222 participants treated for recent HCV, 196 (62% primary infection, 38% reinfection) were included in the cohort at risk for reinfection, of whom 87% identified as gay or bisexual men, 71% had HIV and 20% injected drugs in the month prior to enrolment. During 198 person-years of follow-up, 28 cases of HCV reinfection were identified among 27 participants, for an incidence of 14.2 per 100 person-years [95% confidence interval (CI) 9.8-20.5]. Reinfection was associated with prior HCV reinfection [adjusted hazards ratio (aHR) 2.42; 95% CI 1.08-5.38], injection drug use posttreatment (aHR 2.53; 95% CI 1.14-5.59), condomless anal intercourse with casual male partners (aHR 3.32; 95% CI 1.14-9.65) and geographic region (United Kingdom, aHR 0.21; 95% CI 0.06-0.75). Among gay and bisexual men (GBM), reinfection was also associated with sexualized drug use involving injecting posttreatment (aHR 2.97; 95% CI 1.10-8.02). CONCLUSION High reinfection incidence following treatment for recent HCV among people with ongoing sexual and drug use risk behaviour highlights the need for posttreatment surveillance, rapid retreatment of reinfection and targeted harm reduction strategies.

Abstract
BACKGROUND In 2016, the World Health Assembly adopted the resolution to eliminate viral hepatitis by 2030. This study aims to provide an overview of the burdens of hepatitis B virus (HBV) and hepatitis C virus (HCV) in Europe and their changes from 2010 to 2019 using estimates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. METHODS We used GBD 2019 estimates of the burden associated with HBV-related and HCV-related diseases: acute hepatitis, cirrhosis and other chronic liver diseases, and liver cancer. We report total numbers and age-standardised rates per 100 000 for mortality, prevalence, incidence, and disability-adjusted life-years (DALYs) from 2010 to 2019. For each HBV-related and HCV-related disease and each measure, we analysed temporal changes and percentage changes for the 2010-19 period. FINDINGS In 2019, across all age groups, there were an estimated 2·08 million (95% uncertainty interval [UI] 1·66 to 2·54) incident cases of acute hepatitis B and 0·49 million (0·42 to 0·57) of hepatitis C in Europe. There were an estimated 8·24 million (7·56 to 8·88) prevalent cases of HBV-related cirrhosis and 11·87 million (9·77 to 14·41) of HCV-related cirrhosis, with 24·92 thousand (19·86 to 31·03) deaths due to HBV-related cirrhosis and 36·89 thousand (29·94 to 45·56) deaths due to HCV-related cirrhosis. Deaths were estimated at 9·00 thousand (6·88 to 11·62) due to HBV-related liver cancer and 23·07 thousand (18·95 to 27·31) due to HCV-related liver cancer. Between 2010 and 2019, the age-standardised incidence rate of acute hepatitis B decreased (-22·14% [95% UI -35·44 to -5·98]) as did its age-standardised mortality rate (-33·27% [-43·03 to -25·49]); the age-standardised prevalence rate (-20·60% [-22·09 to -19·10]) and mortality rate (-33·19% [-37·82 to -28·13]) of HBV-related cirrhosis also decreased in this time period. The age-standardised incidence rate of acute hepatitis C decreased by 3·24% (1·17 to 5·02) and its age-standardised mortality rate decreased by 35·73% (23·48 to 47·75) between 2010 and 2019; the age-standardised prevalence rate (-6·37% [-8·11 to -4·32]), incidence rate (-5·87% [-11·24 to -1·01]), and mortality rate (-11·11% [-16·54 to -5·53]) of HCV-related cirrhosis also decreased. No significant changes were observed in age-standardised rates of HBV-related and HCV-related liver cancer, although we observed a significant increase in numbers of cases of HCV-related liver cancer across all ages between 2010 and 2019 (16·41% [2·81 to 30·91] increase in prevalent cases). Substantial reductions in DALYs since 2010 were estimated for acute hepatitis B (-27·82% [-36·92 to -20·24]), acute hepatitis C (-27·07% [-15·97 to -39·34]), and HBV-related cirrhosis (-30·70% [-35·75 to -25·03]). A moderate reduction in DALYs was estimated for HCV-related cirrhosis (-6·19% [-0·19 to -12·57]). Only HCV-related liver cancer showed a significant increase in DALYs (10·37% [4·81-16·63]). Changes in age-standardised DALY rates closely resembled those observed for overall DALY counts, except for HCV-liver related cancer (-2·84% [-7·75 to 2·63]). INTERPRETATION Although decreases in some HBV-related and HCV-related diseases were estimated between 2010 and 2019, HBV-related and HCV-related diseases are still associated with a high burden, highlighting the need for more intensive and coordinated interventions within European countries to reach the goal of elimination by 2030.

Abstract
Although current guidelines recommend that nearly all patients with chronic hepatitis C virus (HCV) infection receive treatment, a substantial proportion remain untreated. We conducted an administrative claims analysis to provide real-world data on treatment patterns and characteristics of treated versus untreated patients among individuals with HCV in the United States. Adults with an HCV diagnosis from 01 July 2016 through 30 September 2020 and continuous health plan enrolment for 12 months before and ≥1 month after the diagnosis date were identified in the Optum Research Database. Descriptive and multivariable analyses were conducted to evaluate the association between patient characteristics and the rate of treatment. Of 24,374 patients identified with HCV, only 30% initiated treatment during follow-up. Factors associated with increased rate of treatment included younger age versus age 75+ (hazard ratio [HR] 1.50-1.83 depending on age group), commercial versus Medicare insurance (HR 1.32), and diagnosis by a specialist versus a primary care physician (HR 2.56 and 2.62 for gastroenterology and infectious disease or hepatology, respectively) (p < .01 for all). Several baseline comorbidities were associated with decreased rate of treatment, including psychiatric disorders (HR 0.87), drug use disorders (HR 0.85) and cirrhosis (HR 0.42) (p < .01 for all). These findings highlight existing HCV treatment inequities, particularly among older patients and those with psychiatric disorders, substance use disorders or chronic comorbidities. Targeted efforts to increase treatment uptake in these populations could mitigate a considerable future burden of HCV-related morbidity, mortality and healthcare costs.

Abstract
INTRODUCTION Exploration of sexual and drug use behaviours following treatment for recent hepatitis C virus (HCV) is limited. This analysis modelled behavioural trajectories following treatment for recent HCV and assessed reinfection. METHODS Participants treated for recent HCV in an international trial (enrolled 2017-2019) were followed at 3-monthly intervals for up to 2 years to assess longitudinal behaviours. Population-averaged changes were assessed using generalized estimating equations. Distinct behavioural trajectories were identified using group-based trajectory modelling. HCV reinfection incidence was calculated using person-years (PY) of observation. RESULTS During the follow-up of 212 participants (84% gay and bisexual men [GBM]; 69% HIV; 26% current injecting drug use [IDU]), behavioural trajectories for IDU and stimulant use (past month) did not change. However, population-averaged decreases in the likelihood of daily IDU (adjusted odds ratio [AOR] 0.83; 95% CI 0.72, 0.95) and opioid use (AOR 0.84; 95% CI 0.75, 0.93) were observed. Among GBM, behavioural trajectories for chemsex did not change. Population-averaged decreases in condomless anal intercourse with casual male partners (CAI-CMP) (AOR 0.95; 95% CI 0.90, 0.99) and group-sex (AOR 0.86; 95% CI 0.80, 0.93) were observed, but masked distinct trajectories. While a proportion had a decreased probability of CAI-CMP (23%) and group-sex (59%) post-treatment, a substantial proportion retained a high probability of these behaviours. High HCV reinfection incidence was observed for the sustained high probability IDU (33.0/100 PY; 95% CI 17.7, 61.3) and chemsex (23.3/100 PY; 95% CI 14.5, 37.5) trajectories. CONCLUSIONS Limited sexual and drug use behavioural change was observed following treatment for recent HCV, supporting access to surveillance and (re)treatment.

METHODS We conducted a retrospective cohort study of HCV-infected patients who initiated OBOT treatment between December 2015 and March 2021 to characterize HCV treatment and assess associations with OBOT retention. HCV treatment was characterized as no treatment, early treatment (< 100 days since OBOT initiation) or late treatment (≥ 100 days). We evaluated associations between HCV treatment and cumulative days in OBOT. A secondary analysis using Cox Proportional Hazards regression was done to determine the rate of discharge over time when comparing those who did versus did not receive HCV treatment as a time-varying covariate. We also analyzed a subset of patients retained at least 100 days in OBOT care and evaluated whether HCV treatment during that period was associated with OBOT retention beyond 100 days. RESULTS Of 191 HCV-infected OBOT patients, 30% initiated HCV treatment, of whom 31% received early treatment and 69% received late treatment. Median cumulative duration in OBOT was greater among those who received HCV treatment (any: 398 days, early: 284 days and late: 430 days) when compared to those who did not receive treatment (90 days). Compared to no HCV treatment, there were 83% (95% CI: 33-152%, P < 0.001), 95% (95% CI: 28%-197%, p = 0.002 and 77% (95% CI: 25-153%, p = 0.002) more cumulative days in OBOT for any, early and late HCV treatment, respectively. HCV treatment was associated with a lower relative hazard for discharge/drop-out, although results did not meet statistical significance (aHR = 0.59;95% CI: 0.34-1.00; p = 0.052). Among the subset of 84 patients retained in OBOT at least 100 days, 18 received HCV treatment during that period. Compared to those who did not receive treatment within the first 100 days, those who received treatment had 57% (95% CI: -3%-152%, p = 0.065) more subsequent days in OBOT. CONCLUSIONS A minority of HCV-infected patients received HCV treatment after initiating OBOT treatment, but those who did had better retention. Further efforts are needed to facilitate rapid HCV treatment and evaluate whether early HCV treatment improves OBOT engagement.

Abstract
Chronic hepatitis C is a major health concern with high morbidity and mortality rates. The introduction of direct acting antivirals (DAAs) as a first-line treatment for hepatitis C virus (HCV) has significantly enhanced HCV eradication. However, DAA therapy is facing rising concerns regarding long-term safety, viral resistance, and reinfection. HCV is associated with different immune alteration mechanisms that can evade immunity and establish persistent infection. One of these suggested mechanisms is the accumulation of myeloid-derived suppressor cells (MDSCs), which is known to accumulate in chronic inflammatory conditions. Moreover, the role of DAA in restoring immunity after successful viral eradication is still unclear and needs further investigations. Thus, we aimed to investigate the role of MDSCs in chronic HCV Egyptian patients and its response to DAA in treated compared with untreated patients. Fifty untreated chronic hepatitis C (CHC) patients, 50 DAA-treated CHC patients, and 30 healthy individuals were recruited. We used flow cytometer analysis to measure MDSCs frequency and enzyme-linked immunosorbent assay analysis to evaluate the serum level of interferon (IFN)-γ. We found a significant elevation in MDSC% among the untreated group (34.5 ± 12.4%) compared with the DAA-treated group (18.3 ± 6.7%), while the control group had a mean of (3.8 ± 1.6%). IFN-γ concentration was higher in treated patients compared with untreated. We also found a significant negative correlation (rs -0.662) (p < 0.001) between MDSC% and IFN-γ concentration among treated HCV patients. Our results revealed important evidence of MDSCs accumulation in CHC patients and partial retrieval of the immune system regulatory function after DAA therapy.

Abstract
Aboriginal and Torres Strait Islander peoples experience a disproportionate burden of hepatitis C virus (HCV) infection. This study assessed the effectiveness of direct-acting antiviral (DAA) therapy among Aboriginal peoples in the three years following universal access in Australia. REACH-C, a national multicentre prospective cohort study, evaluated HCV treatment outcomes from sequential DAA initiations across 33 health services between March 2016 and June 2019. DAA effectiveness was assessed by sustained virological response (SVR) in the total (full analysis set) and effectiveness (modified analysis set excluding those lost to follow-up) populations. Overall, 915 (10%) Aboriginal and 8095 (90%) non-Indigenous people commenced DAA therapy, of whom 30% and 16% reported current injecting drug use and 73% and 42% were treated in primary care, respectively. SVR in the total and effectiveness populations was 74% and 94% among Aboriginal people and 82% and 94% among non-Indigenous people, with loss to follow-up contributing to lower SVR in the total population analysis (22% Aboriginal, 13% non-Indigenous). Among Aboriginal people, returning for follow-up was positively associated with older age (aOR 1.20; 95% CI 1.04, 1.39) and SVR was negatively associated with cirrhosis (aOR 0.39; 95% CI 0.19, 0.80) and prior DAA treatment (aOR 0.14; 95% CI 0.04, 0.49). Factors reflecting higher vulnerability or inequity were not associated with returning for testing or SVR. DAA therapy was highly effective among Aboriginal peoples with HCV treated through primary and tertiary services. Tailored community-led interventions are necessary to optimize follow-up and engagement. Sustained DAA uptake and equitable access to care, treatment and prevention are required for HCV elimination.

Abstract
The World Health Organization envisions the elimination of viral hepatitis by 2030 through reducing prevalence and transmission, increasing diagnostic screening, and expanding treatment coverage. Efforts to micro-eliminate hepatitis in Phetchabun province in Thailand, a region where the prevalence of hepatitis C virus (HCV) infection and liver cancer is higher than elsewhere in the country, began with evaluating the province-wide burden of HCV. Here, we describe a feasibility study to assess active HCV infection by screening Phetchabun residents ages 35 to 69 years for anti-HCV antibodies by using a rapid diagnostic test (RDT) at the point of care. Positive anti-HCV results were further evaluated for active infection using qualitative HCV RNA assay, followed by quantitative HCV viral load determination in a subset of samples. Currently, we have identified 6.2% (10,621/170,163) anti-HCV positive individuals, of whom 74.9% (3,930/5,246) demonstrated detectable viral RNA. Quantitative test found that 97.5% (1,001/1,027) had HCV viral load ≥5,000 IU/mL. Thus, primary screening with anti-HCV RDT followed by qualitative HCV RNA evaluation could identify active and chronic HCV infection in almost all individuals with a viral load ≥5,000 IU/mL, which is the current threshold for treatment dictated by Thailand's National Health Security Office. Our data suggest that qualitative HCV RNA evaluation may obviate the need for the more expensive quantitative HCV viral load test and reduce a significant barrier toward HCV elimination in a middle-income country.

Hepatitis C subtyping assay failure in UK patients born in sub-Saharan Africa: Implications for global treatment and elimination. J Med Virol 2023; 95:e28178. [PMID: 36168235 PMCID: PMC10092547 DOI: 10.1002/jmv.28178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 09/21/2022] [Accepted: 09/26/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND AND AIMS: The newly developed direct-acting antivirals have revolutionized the treatment of chronic hepatitis C virus (HCV), with cure rates as high as 98% in some cohorts. Although genome sequencing has demonstrated that some subtypes of HCV naturally harbor drug resistance associated substitutions (RAS), these are often overlooked as "rarities." Furthermore, commercial subtyping assays and associated epidemiological findings are skewed towards Western cohorts and whole-genome sequencing can be problematic to deploy without significant infrastructure and training support. We thus aimed to develop a simple, robust and accurate HCV subtyping pipeline, to optimize and streamline molecular detection and sequence-based typing of diverse RAS-containing subtypes. METHODS HCV serum derived from 146 individuals, whose likely source of infection was from sub-Saharan Africa (SSA) was investigated with a novel panel of single round polymerase chain reaction (PCR) assays targeting NS5B and NS5A genomic regions. Virus subtype assignments were determined by pairwise-distance analysis and compared to both diagnostic laboratory assignments and free-to-use online typing tools. RESULTS Partial NS5A and NS5B sequences were respectively obtained from 131 to 135 HCV-positive patients born in 19 different countries from SSA but attending clinics in the UK. We determined that routine clinical diagnostic methods incorrectly subtyped 59.0% of samples, with a further 6.8% incorrectly genotyped. Of five commonly used online tools, Geno2Pheno performed most effectively in determining a subtype in agreement with pairwise distance analysis. CONCLUSION This study provides a simple low-cost pathway to accurately subtype in SSA, guide regional therapeutic choice and assist global surveillance and elimination initiatives.

Modeling HCV elimination recovery following the COVID-19 pandemic in the United States: Pathways to regain progress. J Infect Public Health 2023; 16:64-70. [PMID: 36473359 PMCID: PMC9674561 DOI: 10.1016/j.jiph.2022.11.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 10/20/2022] [Accepted: 11/15/2022] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND As of 2019, the United States (US) was not on track to achieve targets for elimination, due to increasing incidence and treatment barriers. In 2020, the COVID-19 pandemic disrupted HCV services globally and in the US. As healthcare services normalize, there is an urgent need to reassess progress and evaluate scenarios that restore a pathway toward HCV elimination. METHODS We updated a validated Markov model to estimate HCV-related morbidity and mortality in the US. Five scenarios were developed to bookend possible HCV outcomes in the wake of the pandemic. These included 1) return to pre-COVID-19 treatment forecasts; 2) achieve elimination targets through treatment and harm reduction; 3) long-term treatment disruptions; 4/5) achieve elimination targets through increased treatment without increased harm reduction, starting in either 2022 or 2025. FINDINGS From 2014-2019, more than 1.2 million patients were treated for HCV in the US. Elimination targets in 2030 could be achieved in the US by treating an additional 3.2-3.3 million patients from 2020 to 2030, or by preventing new infections through expanded harm reduction programs and treating up to 2.7 million patients. Intervention scenarios could prevent over 30,000 HCC cases and over 29,000 liver-related deaths. INTERPRETATION The US has made strides toward HCV elimination, but gains could be lost in the wake of the pandemic. However, it is still possible to avert nearly 30,000 deaths through increased harm reduction and increased treatment rates. This requires a coordinated effort from the entire HCV community.

Abstract
Virological failure occurs in a small proportion of people treated for hepatitis C virus (HCV) with direct-acting antiviral (DAA) therapies. This study assessed retreatment for virological failure in a large real-world cohort. REACH-C is an Australian observational study (n=10843) evaluating treatment outcomes of sequential DAA initiations across 33 health services between March 2016 to June 2019. Virological failure retreatment data were collected until October 2020. Of 408 people with virological failure (81% male; median age 53; 38% cirrhosis; 56% genotype 3), 213 (54%) were retreated once; 15 were retreated twice. A range of genotype specific and pangenotypic DAAs were used to retreat virological failure in primary (n=56) and tertiary (n=157) settings. Following sofosbuvir/velpatasvir/voxilaprevir availability in 2019, the proportion retreated in primary care increased from 21% to 40% and median time to retreatment initiation declined from 294 to 152 days. Per-protocol (PP) sustained virological response (SVR12) was similar for people retreated in primary and tertiary settings (80% vs 81%; p=1.000). In regression analysis, sofosbuvir/velpatasvir/voxilaprevir (vs. other regimens) significantly decreased likelihood of second virological failure (PP SVR12 88% vs. 77%; adjusted odds ratio [AOR] 0.29; 95%CI 0.11-0.81); cirrhosis increased likelihood (PP SVR12 69% vs. 91%; AOR 4.26; 95%CI 1.64-11.09). Indigenous Australians had lower likelihood of retreatment initiation (AOR 0.36; 95%CI 0.15-0.81). Treatment setting and prescriber type were not associated with retreatment initiation or outcome. Virological failure can be effectively retreated in primary care. Expanded access to simplified retreatment regimens through decentralised models may increase retreatment uptake and reduce HCV-related mortality.

Abstract
Microelimination targets specific subpopulations and/or geographic settings for hepatitis C virus (HCV) elimination. This review reports on global HCV microelimination literature published from 2013 to 2020. Data were extracted from publications to report a score based on the four key components defining microelimination. Sustained virologic response (SVR) and treatment initiation proportions were calculated for each manuscript and grouped means of these estimates were compared depending on microelimination score and care setting. A total of 83% of the studies were from high-income settings and mainly included people who use drugs or those incarcerated. Among manuscripts, 18 had "low" microelimination scores, 11 had "high" scores, and the differences in mean proportion who initiated treatment and achieved SVR between low and high score groups were statistically significant. Microelimination can be a useful complementary strategy for driving engagement in HCV treatment and cure. Our analysis suggests that adhering to more of the core microelimination components can improve outcomes. This study is registered with Prospero, registration identification: CRD42020175211.

Abstract
Background This commentary explores the lessons learned during implementation of a peer-facilitated hepatitis C virus (HCV) testing and treatment access project called the Live Hep C Free (LHCF) project in contributing to micro-elimination efforts.
Case presentation The LHCF project aims to facilitate access to on-the-spot HCV testing, treatment, and care in priority settings through partnership between a peer worker (PW) and a clinical nurse. Since the start of the project in January 2018, 4515 people were engaged about HCV and encouraged to access on-site HCV health care, and over 1000 people were screened for HCV and liver health, while almost 250 people accessed HCV treatment through the project. This commentary is intended to prompt discussion about incorporating peer-centred HCV health programs into priority sites. HCV care-delivery models such as the LHCF project can continue to contribute to micro-elimination of HCV in key settings to increase treatment uptake amongst high prevalence and/or marginalised populations and support progress toward national elimination targets. Conclusions The LHCF project has been able to highlight the benefits of incorporating trustworthy, efficient, and convenient peer-centred health services to engage and support vulnerable populations through HCV testing and treatment, particularly individuals who have historically been disconnected from the health care system. Additional attention is needed to ensure ongoing funding support to sustain the project and deliver at scale and in expanding evaluation data to examine the operation and outcomes of the project in more detail.

Compositions of gut microbiota before and shortly after hepatitis C viral eradication by direct antiviral agents. Sci Rep 2022; 12:5481. [PMID: 35361930 PMCID: PMC8971444 DOI: 10.1038/s41598-022-09534-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Accepted: 03/08/2022] [Indexed: 12/24/2022] Open
Abstract
It is unclear whether dysbiosis in hepatitis C virus (HCV) infected patients results from the viral infection per se or develops as a result of hepatic dysfunction. We aimed to characterize compositions in gut microbiome before and shortly after HCV clearance. In this prospective cohort study, adult patients with confirmed HCV viremia were screened before receiving direct antiviral agents. Those with recent exposure to antibiotics or probiotics (within one month), prior abdominal surgery, or any malignancy were ineligible. Stool was collected before antiviral therapy started and at 12 weeks after the treatment completed. From the extracted bacterial DNA, 16 s rRNA gene was amplified and sequenced. Each patient was matched 1:2 in age and sex with uninfected controls. A total of 126 individuals were enrolled into analysis. The gut microbiome was significantly different between HCV-infected patients (n = 42), with or without cirrhosis, and their age-and sex-matched controls (n = 84) from the levels of phylum to amplicon sequence variant (all p values < 0.01 by principal coordinates analysis). All patients achieved viral eradication and exhibited no significant changes in the overall composition of gut microbiome following viral eradication (all p values > 0.5), also without significant difference in alpha diversity (all p values > 0.5). For the purpose of exploration, we also reported bacteria found differently abundant before and after HCV eradication, including Coriobacteriaceae, Peptostreptococcaceae, Staphylococcaceae, Morganellaceae, Pasteurellaceae, Succinivibrionaceae, and Moraxellaceae. Gut microbiota is altered in HCV-infected patients as compared with uninfected controls, but the overall microbial compositions do not significantly change shortly after HCV eradication.

A Digital Case-Finding Algorithm for Diagnosed but Untreated Hepatitis C: A Tool for Increasing Linkage to Treatment and Cure. Hepatology 2021; 74:2974-2987. [PMID: 34333777 PMCID: PMC9299620 DOI: 10.1002/hep.32086] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 06/29/2021] [Accepted: 07/22/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND AND AIMS Although chronic HCV infection increases mortality, thousands of patients remain diagnosed-but-untreated (DBU). We aimed to (1) develop a DBU phenotyping algorithm, (2) use it to facilitate case finding and linkage to care, and (3) identify barriers to successful treatment. APPROACH AND RESULTS We developed a phenotyping algorithm using Java and SQL and applied it to ~2.5 million EPIC electronic medical records (EMRs; data entered January 2003 to December 2017). Approximately 72,000 EMRs contained an HCV International Classification of Diseases code and/or diagnostic test. The algorithm classified 10,614 cases as DBU (HCV-RNA positive and alive). Its positive and negative predictive values were 88% and 97%, respectively, as determined by manual review of 500 EMRs randomly selected from the ~72,000. Navigators reviewed the charts of 6,187 algorithm-defined DBUs and they attempted to contact potential treatment candidates by phone. By June 2020, 30% (n = 1,862) had completed an HCV-related appointment. Outcomes analysis revealed that DBU patients enrolled in our care coordination program were more likely to complete treatment (72% [n = 219] vs. 54% [n = 256]; P < 0.001) and to have a verified sustained virological response (67% vs. 46%; P < 0.001) than other patients. Forty-eight percent (n = 2,992) of DBU patients could not be reached by phone, which was a major barrier to engagement. Nearly half of these patients had Fibrosis-4 scores ≥ 2.67, indicating significant fibrosis. Multivariable logistic regression showed that DBUs who could not be contacted were less likely to have private insurance than those who could (18% vs. 50%; P < 0.001). CONCLUSIONS The digital DBU case-finding algorithm efficiently identified potential HCV treatment candidates, freeing resources for navigation and coordination. The algorithm is portable and accelerated HCV elimination when incorporated in our comprehensive program.

Viruses 2021; 13:v13112140. [PMID: 34834947 PMCID: PMC8619706 DOI: 10.3390/v13112140] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 10/16/2021] [Accepted: 10/19/2021] [Indexed: 01/28/2023] Open
Abstract
Since 2020, the US Preventive Services Taskforce has recommended expanding hepatitis C virus (HCV) screening to include ages 18−79, in addition to baby boomers (born 1945−1965) and those at-risk for hepatitis C virus. This retrospective cohort analysis compared patients (18 years and above) tested for HCV through usual care versus a coordinator-supported program (HCV pathway) during 2015−2018 within Kaiser Permanente Mid-Atlantic States (KPMAS). In total, 131,176 patients were tested through the HCV pathway and 128,311 through usual care (non-standardized testing). Of those tested, 1.6% (HCV pathway) and 0.5% (usual care) had chronic HCV. Of those with chronic HCV, more patients tested within the HCV pathway completed hepatic transient elastography (82.6% HCV pathway vs. 45.6% usual care; p < 0.001) and a gastroenterology visit (72.2% HCV pathway vs. 46.5% usual care; p < 0.001), and had filled prescriptions for treatment (56.5% HCV pathway vs. 40.3% usual care; p < 0.001). The median time to complete each step was shorter for those tested through the HCV pathway (hepatic transient elastography (26 vs. 118 days), gastroenterology visit (63 vs. 131 days), and prescription fill (222 vs. 326 days)). More patients tested through a coordinator-supported, standardized testing pathway completed the necessary testing steps, in less time, compared to usual care. These findings may inform institutions seeking to create effective population-wide testing programs for HCV and other conditions.

Effectiveness of treatment for hepatitis C virus reinfection following direct acting antiviral therapy in the REACH-C cohort. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103422. [PMID: 34426040 DOI: 10.1016/j.drugpo.2021.103422] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 07/07/2021] [Accepted: 08/06/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND Direct acting antiviral (DAA) therapy is highly effective for hepatitis C virus (HCV) infection, but reinfection following treatment may compromise benefits of cure. This study assessed the real-world effectiveness of treatment for reinfection. METHODS Real-world effectiveness of antiviral therapy in chronic hepatitis C (REACH-C) is an observational study evaluating treatment outcomes following sequential DAA initiations across 33 health services in Australia between March 2016-June 2019. Reinfection was defined by post-treatment genotype switch or HCV viraemia after sustained virologic response (SVR12). RESULTS Of the 10,843 individuals initiating DAA therapy post-treatment viraemia was reported in 526 of whom 99 were reinfections. Treatment for reinfection occurred in 88 individuals. In those with available treatment outcomes, SVR12 was similar to initial treatment in the overall REACH-C cohort (95% vs 95%; p = 0.745) and comparable across primary, tertiary, and prison settings. Classifying unknown treatment outcomes as failures, SVR12 for treatment of reinfection was lower than initial treatment in REACH-C (67% vs 81%; p = 0.002), due to higher lost to follow-up. CONCLUSIONS Treatment of reinfection is highly effective and can be delivered in non-specialist settings. Access to treatment for reinfection in high-risk populations is crucial to HCV elimination.

'Treat my whole person, not just my condition': qualitative explorations of hepatitis C care delivery preferences among people who inject drugs. Addict Sci Clin Pract 2021; 16:52.

Abstract
Background The advent of direct-acting antivirals (DAAs)—a form of hepatitis C (HCV) treatment associated with shorter treatment course and greater efficacy—offers an unprecedented opportunity to eliminate HCV, but only if care delivery systems are developed to extend treatment to people who inject drugs (PWID). To support the design of a community-pharmacy program, we explored perspectives of PWID with chronic HCV with regard to barriers, motivators, preferences, and prior experiences related to HCV treatment and pharmacists. Methods We conducted semi-structured interviews with people living with HCV who reported active injection drug use. Participants were recruited from local community service and clinical organizations in the Seattle, Washington region, and focus groups and interviews were conducted in-person or via phone/video-conference. Rapid Assessment Process was used to analyze qualitative data. Dual coders used structured templates to summarize findings and engaged in iterative review to identify themes. Results Among the 40 participants, 65% were male, 52.5% were white, and 80% were not stably housed. On average, participants had been injecting drugs for 14 years and living with HCV for 6 years. Analyses revealed 3 themes: (1) limited knowledge regarding HCV and DAA treatments; (2) barriers/motivators for receiving treatment included fear of side effects, prior stigmatizing behaviors from physicians, and desire to protect relatives and the PWID community from HCV transmission; and (3) preferences for HCV care delivery, including a need for person-centered, low-barrier, and collaborative treatment integrated with other care (e.g. primary care and addiction treatment) for PWID. Participants were generally receptive to a community-pharmacy model for HCV treatment, but prior interactions with pharmacists were mixed and there were some concerns expressed that care delivered by pharmacists would not be equivalent to that of physicians. Conclusions Even in the direct-acting antivirals era, people who inject drugs still face major barriers to hepatitis C treatment which may be reduced by providing low-barrier points of access for care through pharmacists. Key recommendations for community-pharmacy design included providing care team training to reduce stigma and ensuring care team structures and culture target PWID-specific needs for education and engagement.

Ultrasensitive electrochemical detection of hepatitis C virus core antigen using terminal deoxynucleotidyl transferase amplification coupled with DNA nanowires. Mikrochim Acta 2021; 188:285.

Abstract
Early diagnosis of hepatitis C virus (HCV) infection is essential to prevent disease from spreading and progression. Herein, a novel electrochemical biosensor was developed for ultrasensitive detection of HCV core antigen (HCVcAg) based on terminal deoxynucleotidyl transferase (TdT) amplification and DNA nanowires (DNW). After sandwich-type antibody-antigen recognition, the antibody-conjugated DNA was pulled to the electrode surface and further extended into a long DNA sequence by robust TdT reaction. Then, large numbers of methylene blue-loaded DNW (MB@DNW) as signal labels are linked to the extended DNA sequence. This results in an amplified electrochemical signal for HCVcAg determination, typically measured at around -0.25 V (Ag/AgCl). Under the optimum conditions, the proposed biosensor achieved a wide linear range for HCVcAg from 0.1 to 312.5 pg/mL with a low limit of detection of 32 fg/mL. The good practicality of the biosensor was demonstrated by recovery experiment (recoveries from 98 to 104% with RSD of 2.5-4.4%) and comparison with enzyme-linked immunosorbent assay (ELISA). Given the highlighted performance, the biosensor is expected to act as a reliable sensing tool for HCVcAg determination in clinics. Schematic representation of the ultrasensitive electrochemical biosensor based on terminal deoxynucleotidyl transferase (TdT) amplification linked with methylene blue-loaded DNA nanowires (MB@DNW), which can be applied to the determination of hepatitis C virus core antigen (HCVcAg) in clinical samples. dTTPs, 2'-deoxythymidine 5'-triphosphate.

Abstract
BACKGROUND: The Canadian Liver Foundation recommends routine hepatitis C (HCV) screening for Canadians born between 1945 and 1975. This study aimed to determine the feasibility and outcomes of targeted birth cohort HCV screening during routine outpatient endoscopic procedures in a tertiary care hospital. METHODS: We conducted a prospective cohort study of individuals born between 1945 and 1975 who attended outpatient endoscopy procedures at Kingston Health Sciences Centre from 2017 to 2019. Patients who consented received the HCV OraSure point-of-care test for the HCV antibody (HCV Ab). If positive, serum for HCV RNA was sent, and patients were linked to care with a hepatologist. RESULTS: 2,179 patients met birth cohort criteria for HCV screening. Of those, 1,079 (49.5%) were approached for study inclusion, and 160 (15.0%) declined participation, leaving 912 patients who provided consent. The median age was 62 years (IQR 55–67). Overall, 6/912 (0.7%) of participants were HCV Ab positive and 5/912 (0.6%) were HCV RNA positive. Four were linked to care for consideration of direct-acting antiviral (DAA) therapy, 3 received DAA treatment, and all 3 achieved sustained virologic response (SVR). CONCLUSIONS: Birth cohort screening for HCV in an outpatient endoscopy unit identified an HCV prevalence similar to population estimates. In this model, however, 50% of eligible patients were not approached for screening. Linkage to care for assessment of treatment was high at 80%, and of those who received therapy, all achieved SVR. These results suggest this cohort is a suitable population for HCV screening; however, we need strategies to increase recruitment of all eligible individuals.

Abstract
Aim: HCV diagnosis will become the bottleneck in eliminating hepatitis C. Simple, accurate and cost-effective testing strategies are urgently needed to improve hepatitis C screening and diagnosis. Materials & methods: Performance of seven rapid diagnostic tests (RDT) have been assessed in a large series (n = 498) of serum or plasma specimens collected in France and in Cameroon. Results: Specificity varied from 96.1 to 100%. The clinical sensitivity, compared with immunoassays as the reference, was high for all seven RDT (97.2-100%). The Multisure HCV antibody assay and OraQuick HCV rapid antibody test reached sensitivity ≥99%. Conclusion: A number of RDT may be suitable for WHO prequalification and may be implemented in the framework of large-scale low-cost treatment programs to achieve the WHO viral hepatitis objectives by 2030.

Abstract
This Italian observational real-world study aims to assess in chronic hepatitis C virus (HCV) patients treated with pangenotypic direct acting agents (pDAAs) glecaprevir/pibrentasvir (GLE/PIB) or sofosbuvir/velpatasvir (SOF/VEL) the potential drug-drug interactions (DDIs) with concomitant medications prescribed, with a focus on cardiovascular and system nervous (CNS) co-medications. Data were collected from administrative databases covering 6.9 million health-assisted individuals. All patients prescribed SOF/VEL or GLE/PIB between 11/2017 and 12/2018 were included. Patients were analyzed while on DAA. DDIs were identified according to the Liverpool University tool. Overall, 3181 HCV patients were included: 1619 in the GLE/PIB cohort and 1562 in the SOF/VEL cohort. SOF/VEL patients were generally older than GLE/PIB ones (mean age 58.4 vs. 53.1, p < 0.001) and had more cardiovascular and CNS comorbidities (58% vs. 42%, p < 0.001 and 33% vs. 28%, p = 0.002, respectively). Contraindications due to DDIs in the GLE/PIB cohort affected 9.3% and 3.2% of patients before and on DAA, respectively, while the percentages in the SOF/VEL cohort were 3.2% before and 0.4% after pDAAs initiation. Among GLE/PIB patients, 2.7% had cardiovascular drugs (all statins) contraindicated while on DAA. The potential DDIs between cardiovascular drugs and SOF/VEL were mainly with statins (5%). SOF/VEL was prescribed in patients with older age and with more cardiovascular and CNS comorbidities. Despite this, a proportion of contraindicated drugs lower than that of GLE/PIB was registered.

Abstract
Background Direct-acting antivirals can cure hepatitis C virus (HCV). Persons with HCV/HIV and living with substance use are disadvantaged in benefiting from advances in HCV treatment. Methods In this randomized controlled trial, participants with HCV/HIV were randomized between February 2016 and January 2017 to either care facilitation or control. Twelve-month follow-up assessments were completed in January 2018. Care facilitation group participants received motivation and strengths-based case management addressing retrieval of HCV viral load results, engagement in HCV/HIV care, and medication adherence. Control group participants received referral to HCV evaluation and an offer of assistance in making care appointments. Primary outcome was number of steps achieved along a series of 8 clinical steps (eg, receiving HCV results, initiating treatment, sustained virologic response [SVR]) of the HCV/HIV care continuum over 12 months postrandomization. Results Three hundred eighty-one individuals were screened and 113 randomized. Median age was 51 years; 58.4% of participants were male and 72.6% were Black/African American. Median HIV-1 viral load was 27 209 copies/mL, with 69% having a detectable viral load. Mean number of steps completed was statistically significantly higher in the intervention group vs controls (2.44 vs 1.68 steps; χ 2 [1] = 7.36, P = .0067). Men in the intervention group completed a statistically significantly higher number of steps than controls. Eleven participants achieved SVR with no difference by treatment group. Conclusions The care facilitation intervention increased progress along the HCV/HIV care continuum, as observed for men and not women. Study findings also highlight continued challenges to achieve individual-patient SVR and population-level HCV elimination. Clinical Trials Registration NCT02641158.

Abstract
Safe and effective treatment with direct-acting antivirals (DAAs) has ushered in an era in which hepatitis C virus (HCV) elimination, as set out by the World Health Organization, is possible. However, alcohol use disorder (AUD) has the potential to reduce the benefits of prevention interventions and reduce access to and continuity of HCV care in at-risk populations, such as people who inject drugs (PWID). We review the literature on the consequences of AUD on the effectiveness of HCV prevention and the cascade of care in PWID and provide recommendations for future research in the field of alcohol use and HCV.

A Two-Year Outcome Evaluation of Government-Led Initiative to Upscale Hospital-based Hepatitis C Treatment Using a Standard Two-Drug Regimen in Malaysia. HEPATITIS MONTHLY 2021.

Abstract
Background: Malaysia has been fully committed to the global endeavor to eliminate hepatitis C virus (HCV) infection by 2030. In early 2018, the Ministry of Health (MOH) embarked on a “one-size-fits-all strategy” by introducing generic versions of sofosbuvir and daclatasvir as the standard treatment for HCV infection in public hospitals nationwide. Objectives: To evaluate the outcomes of such an initiative in multiple aspects, including the number and characteristics of patients treated, the extent of evidence-based drug use, the treatment completion status, individual responses to treatment, common side effects of treatment, and its economic implications. Methods: The findings were generated from the data compiled by the MOH, capturing the information regarding the treatment provided to adult HCV-infected patients in 16 selected hospitals between April 2018 and March 2020, along with the drug costs incurred. Results: A total of 1,797 patients were treated, nearly four times more than the patients receiving interferon-based treatment across the country in the preceding two years. Approximately one-third of them had liver cirrhosis, and the main HCV genotypes were 3 (46.9%) and 1a (20.0%). Dosing, treatment duration and the addition of ribavirin to the treatment generally agreed with the recommendations of the MOH. More than 90% of the patients completed the treatment course, and a sustained virologic response (SVR) rate of 95.4% (95% CI: 94.2, 96.7%) was recorded in those with a known treatment outcome (n = 1,163). The SVR achievement did not vary across HCV genotypes and cirrhosis status, but those ≥ 50 years of age (adjusted OR: 2.13; 95% CI: 1.16, 3.92) were more likely to fail the treatment. Side effects were rare. Anemia and fatigue caused treatment discontinuation in only 0.3% of the patients. The total drug expenditure reached US$678,258.20, and the mean cost of a 12-week treatment course of sofosbuvir and daclatasvir (US$235.16) was lower than the cost expected by the MOH (US$300). Conclusions: The findings demonstrate a high degree of real-world effectiveness, safety, and affordability of the standard treatment, suggesting that such a government-led initiative was reasonable and timely and could be extended to include more public health institutions.

Abstract
At the beginning of this decade, an estimated 71 million people were living with chronic hepatitis C virus (HCV) infection worldwide. After the acute stage of HCV infection, 18-34% of individuals exhibit spontaneous clearance. However, the remaining 66-82% of infected individuals progress to chronic HCV infection and are at subsequent risk of progression to hepatic fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Chronic hepatitis C progression is generally slow during the first two decades of infection, but can be accelerated during this time in association with advancing age and cofactors, such as heavy alcohol intake and human immunodeficiency virus (HIV) co-infection. Since acute HCV infection is generally asymptomatic, HCV goes undiagnosed in a significant percentage of infected individuals. In 2014, direct-acting antiviral (DAA) therapy for chronic HCV was developed, which has increased the cure rates to nearly 100%. DAA therapy is among the best examples of success in the fight against viral infections. DAAs have transformed HCV management and have opened the door for the global eradication of HCV.

Abstract
Background Injecting drug use is a major driver of hepatitis C virus (HCV) spread worldwide, and the World Health Organization (WHO) has identified people who inject drugs (PWID) as a key population to target for HCV screening and care. Point-of-care (POC) hepatitis C tests and dried blood spot (DBS) sampling offer benefits for the management of patients with HCV infection by increasing HCV testing and linkage to care in different nonclinical settings. The aims of this prospective study were to evaluate the feasibility and the acceptability of use HCV ribonucleic acid (RNA) POC and fingerstick DBS testing in social-medical risk-reduction centers and to describe the cascade of care among PWID in France. Methods Between June 2018 and February 2019, 89 consecutive HCV-seropositive PWID attending 2 drug treatment services and 1 supervised consumption room in inner Paris were invited to participate in further evaluation, undergoing a clinical review with a liver assessment and blood tests including fingerstick capillary whole blood POC HCV RNA testing and fingerstick DBS sampling. Results Of the 89 participants enrolled, HCV RNA was detected in 34 (38.6%) participants. Fingerstick whole blood POC RNA testing and HCV RNA detection from DBS sample were feasible and acceptable among PWID with no major difference in terms of HCV RNA detection rate. Overall, 16 participants received pan-genotypic antiviral treatment. The proportion of PWID with sustained virologic response at 12 weeks was 81.2%, with data for 3 patients still pending. Conclusions One-step screening strategy based on the detection of HCV RNA would engage people in care for treatment scale-up and HCV elimination.
