Abstract
OBJECTIVE If untreated, hepatitis C virus (HCV) leads to poor health outcomes, including liver disease and death, particularly among people with HIV (PWH). We describe trends over time in incidence rates of HCV diagnoses among PWH in the state of Georgia. METHODS We constructed a retrospective cohort of PWH in Georgia by using matched HIV and HCV case surveillance data from people diagnosed with HCV infection from January 1, 2014, through December 31, 2019. We calculated annual incidence rates per 1000 person-years and estimated trends over time in HCV diagnoses among the cohort of PWH by demographic characteristics and HIV care outcomes using Poisson regression analysis, with α = .05 considered significant. RESULTS From 2014 through 2019, among 49 530 PWH in Georgia, 1945 (3.9%) were diagnosed with HCV infection. During this period, overall incidence per 1000 person-years of newly diagnosed HCV infection among PWH decreased from 8.7 to 4.5 (P for trend < .001). However, from 2014 through 2019, the annual incidence rates of PWH who were newly diagnosed with HCV infection increased from 4.6 to 7.1 (P for trend = .003) among people born from 1980 through 1989 and from 3.3 to 12.8 (P for trend < .001) among people born in 1990 or later. CONCLUSION Strategies are needed to increase prevention, diagnosis, and treatment of HIV/HCV coinfection, particularly among PWH born in 1980 and later. Routine linkage of state surveillance data can inform prioritization of PWH at highest risk of HCV infection.

Tu Y, Tang X, Zhou D, Shao H, Liang L, Tang W. Is it time for China to prioritize pan-genotypic regimens for treating patients with hepatitis C? COST EFFECTIVENESS AND RESOURCE ALLOCATION 2024; 22:11. [PMID: 38321475 PMCID: PMC10848349 DOI: 10.1186/s12962-024-00519-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 01/24/2024] [Indexed: 02/08/2024] Open
Abstract
INTRODUCTION The treatment of hepatitis C has entered the pan-genotypic era, but the effectiveness is not good for the genotype 3b patients who have a large proportion in China. The guidelines for hepatitis C recommend the use of gene-specific regimens when the regional 3b prevalence rate greater than 5%. This study is to explore rationality of this proportion and the cost-effectiveness to implement pan-genotypic regimens in China. METHODS A decision Markov model was developed from the health system perspective to evaluate the effectiveness and cost-effectiveness between pan-genotypic and gene-specific treatment regimens for hepatitis C patients. Additionally, we set a regional genotype 3b patient proportion of 0-100% to explore at which proportion it is necessary to perform genotype identification and typing therapy on patients. Model parameters were derived from published literature and public databases. Effectiveness was measured by cured patient numbers, newly diagnosed cases of decompensated cirrhosis, hepatocellular carcinoma, need for liver transplantation, and quality-adjusted life years (QALYs). Cost-effectiveness outcomes included costs and the incremental cost-effectiveness ratio (ICER). The 1-3 times 2022 Chinese per capita gross domestic product was used as the willingness-to-pay threshold. One-way and probabilistic sensitivity analyses were performed to assess the uncertainty of the model parameters. RESULTS Compared with gene-specific regimens, pan-genotypic regimens resulted in an additional 0.13 QALYs and an incremental cost of $165, the ICER was $1,268/QALY. From the view of efficacy, the pan-genotypic regimens cured 5,868 more people per 100,000 patients than gene-specific regimens, avoiding 86.5% of DC cases, 64.6% of HCC cases, and 78.2% of liver transplant needs. Identifying 3b patients before treatment was definitely cost-effectiveness when their prevalence was 12% or higher. The results remained robust in sensitivity analyses. CONCLUSIONS In China, the prioritized recommendation of pan-genotypic therapeutics proves to be both cost-effective and efficacious. But, in regions where the prevalence of genotype 3b exceeds 12%, it is necessary to identify them to provision of more suitable therapies.

The impact of expanded access to direct acting antivirals for Hepatitis C virus on patient outcomes in Canada. PLoS One 2023; 18:e0284914. [PMID: 37552677 PMCID: PMC10409286 DOI: 10.1371/journal.pone.0284914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Accepted: 07/22/2023] [Indexed: 08/10/2023] Open
Abstract
BACKGROUND Hepatitis C virus (HCV) has high global prevalence and can lead to liver complications and death. Access to direct-acting antivirals (DAAs) in Canada increased following several policy changes, however the real-world impact of expanded DAA access and increased use of these drugs is unknown. OBJECTIVE We aimed to determine the early change in rates of HCV-related hospitalizations overall and HCV-related hospitalizations with hepatocellular carcinoma (HCC) after expanded DAA access. METHODS We conducted a population-based time series analysis using national administrative health databases in Canada. Rates of HCV-related hospitalizations and HCV-related hospitalizations with HCC were enumerated monthly between April 2006 and March 2020. We used Autoregressive Integrated Moving Average (ARIMA) models with ramp functions in October 2014 and January 2017 to evaluate the impact of policies to expand DAA access on hospitalization outcomes. RESULTS Rates of HCV-related hospitalizations in Canada increased between 2006 and 2014, and gradually declined thereafter. The decrease after October 2014, or the first policy change, was significant (p = 0.0355), but no further change was found after the second policy change in 2017 (p = 0.2567). HCV-related hospitalizations with HCC increased until end of 2013, followed by a plateau, before declining in 2016. No significant shifts were found after the first policy change in 2014 (p = 0.1291) nor the second policy change in 2017 (p = 0.6324). Subgroup analyses revealed that those aged 50-64 and males had observable declines in rates of HCV-related hospitalizations in the year prior to the first policy change. CONCLUSIONS Expanding DAA access was associated with a drop in HCV-related hospitalizations in the overall Canadian population coinciding with the 2014 policy change. In light of the time required for HCV-related complications to manifest, continued ongoing research examining the real-world effectiveness of DAAs is required.

Abstract
INTRODUCTION Chronic infection due to hepatitis C virus (HCV) is frequently asymptomatic even in advanced stages of liver disease. Implementation of a screening program based on different HCV tests may enable an earlier diagnosis of HCV liver disease and subsequent application of highly effective treatment. PATIENTS AND METHODS A Markov model which compares three different screening strategies for hepatitis C versus no screening in low-risk prevalence (general population) and high-risk prevalence population (people who inject drugs or prison population) was designed, taking into account age at the start of screening and participation. The three strategies were: 1) serological detection of antibodies against the HCV, 2) dried blood spot test (DBS) to detect antibodies against HCV and 3) detection of RNA from HCV. Quality-adjusted life-years (QALY) were taken as a measurement of effectiveness. The incremental cost-effectiveness ratio (ICER) was calculated and a deterministic and probabilistic sensitivity analysis was performed. RESULTS All three screening strategies were found to be cost-effective with an ICER of €13,633, €12,015 and €12,328/QALY for AntiHCV, DBS-AntiHCV and DBS-RNA HCV, respectively. There was a decrease in mortality due to liver disease in comparison to no screening for AntiHCV (40.7% and 52%), DBS-AntiHCV (45% and 80%) and DBS-RNA HCV (45.2% and 80%) for low-prevalence and high-prevalence populations, respectively. CONCLUSION All test interventions for HCV screening are cost-effective for the early detection of HCV infection, also achieving a reduction in mortality. Thus, implementation of screening programs for HCV should not be halted by decisions on monetary policy.

Efficacy and safety of direct-acting antiviral therapy for hepatitis C virus in elderly patients (≥65 years old): A systematic review and meta-analysis. J Viral Hepat 2022; 29:496-517. [PMID: 35357774 DOI: 10.1111/jvh.13679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 02/07/2022] [Accepted: 03/11/2022] [Indexed: 12/09/2022]
Abstract
Direct-acting agents (DAAs) have launched a new era of hepatitis C virus (HCV) treatment. As aged individuals comprise a large percentage of HCV-infected patients, the effectiveness and safety of DAAs in the elderly have come under scrutiny. This meta-analysis aimed to evaluate the efficacy and safety of DAAs in elderly patients. After a systematic search in PubMed (MEDLINE), Embase, OVID MEDLINE, the Cochrane Library and other databases, two investigators reviewed relevant abstracts and selected manuscripts for examination. The sustained virologic response (SVR) and adverse event (AE) rates were calculated with a random-effects model. Ninety studies evaluating SVR rates of elderly patients (≥65 years old) receiving DAAs were selected. DAAs in elderly patients exhibited a notable SVR rate of 96% (95% confidence interval [CI]: 95%-97%), accompanied by comparable rates in subgroup analyses. The comparison of SVR rates in elderly and non-elderly patients indicated no significant discrepancy (odds ratio [OR] 1.01, 95% CI: 1.00-1.01). The overall event rate of AEs was 45% (95% CI: 31%-60%), though AE rates varied by subgroups. Furthermore, AEs were comparatively more frequent (OR 1.15, 95% CI: 1.04-1.28) in the elderly than non-elderly, especially in subgroups such as SAE (OR 1.89, 95% CI: 1.52-2.36) and dose reduction in ribavirin (OR 1.90, 95% CI: 1.53-2.36). However, in the ribavirin (RBV)-free regimen, there was no significant difference in the incidence of AEs between the elderly and non-elderly groups. DAAs have high efficacy in elderly patients. Considering the possibility of AE, the RBV-free regimen should be given prior consideration for the treatment of elderly patients with HCV.

Abstract
OBJECTIVES Chronic hepatitis C (CHC) infection affects more than 70 million people worldwide and imposes considerable health and economic burdens on patients and society. This study estimated 2 understudied components of the economic burden, patient out-of-pocket (OOP) costs and time costs, in patients with CHC in a tertiary hospital clinic setting and a community clinic setting. METHODS This was a multicenter, cross-sectional study with hospital-based (n = 174) and community-based (n = 101) cohorts. We used a standardized instrument to collect healthcare resource use, time, and OOP costs. OOP costs included patient-borne costs for medical services, nonprescription drugs, and nonmedical expenses related to healthcare visits. Patient and caregiver time costs were estimated using an hourly wage value derived from patient-reported employment income and, where missing, derived from the Canadian census. Sensitivity analysis explored alternative methods of valuing time. Costs were reported in 2020 Canadian dollars. RESULTS The mean 3-month OOP cost was $55 (95% confidence interval [CI] $21-$89) and $299 (95% CI $170-$427) for the community and hospital cohorts, respectively. The mean 3-month patient time cost was $743 (95% CI $485-$1002) (community) and $465 (95% CI $248-$682) (hospital). The mean 3-month caregiver time cost was $31 (95% CI $0-$63) (community) and $277 (95% CI $174-$380) (hospital). Patients with decompensated cirrhosis bore the highest costs. CONCLUSIONS OOP costs and patient and caregiver time costs represent a considerable economic burden to patient with CHC, equivalent to 14% and 21% of the reported total 3-month income for the hospital-based and community-based cohorts, respectively.

Abstract
World Health Organization (WHO) calls for global hepatitis strategy to eliminate viral hepatitis by 2030. Yet many high-income countries were unable to achieve HCV elimination by 2030. Apart from the tremendous efforts and resources from the governments, many non-government organizations (NGOs) have been working very hard to contribute to HCV elimination. In Hong Kong, the Center for Liver Health of The Chinese University of Hong Kong (CUHK) has been working very closely with various NGOs to educate and screen subjects who previously use intravenous drugs. In this review article, we discussed in details the New Life New Liver Program, and the barriers to HCV elimination, with special highlight the role of NGOs in overcoming the barriers.

In Vitro Antiviral Activity of Tyrosinase from Mushroom Agaricus bisporus against Hepatitis C Virus. Pharmaceuticals (Basel) 2021; 14:ph14080759.

Abstract
Tyrosinases from a commercial Agaricus bisporus protein extract and directly isolated from white mushrooms were purified in order to obtaining the well-known tyrosinase from A. bisporus (TyrAB) of 45 kDa and a newly discovered 50 kDa tyrosinase isoform (Tyr50 kDa), and tested showing high antiviral activity against the hepatitis C virus for the first time. Cell toxicity and antiviral activity of tyrosinases were determined in cultured Huh 5-2 liver tumor cells transfected with a replicon system (a plasmid that includes all non-structural hepatitis C virus proteins and replicates autonomously). TyrAB was able to inhibit the replication of the hepatitis C virus without inducing toxicity in liver cells. In addition, the post-translational isoform Tyr50 kDa showed higher antiviral capacity than the former (up to 10 times greater), also exhibiting 10 times higher activity than the commercial drug Ribavirin®. This antiviral activity was directly proportional to the enzymatic activity of tyrosinases, as no antiviral capacity was observed in the inactive form of the enzymes. The tyrosinases approach could represent a new antiviral inhibition mechanism, through a plausible catalytic mechanism of selective hydroxylation of the key role of tyrosine residues in viral proteases.

Abstract
Objective This study aimed to estimate the cost-effectiveness of direct-acting antivirals (DAAs) among patients with non-genotype 1 for the eradication of hepatitis C virus (HCV) infection in China. Methods A decision-analytic Markov model was developed to estimate the lifetime costs, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs) for DAAs and pegylated interferon plus ribavirin (PEG-RBV) from a societal perspective. The model inputs were derived from the literature, a patient survey, HCV expert opinions and a specialised drug price database available in China. Sensitivity analysis was conducted to evaluate the model robustness and calculate reasonable prices of DAAs. Results For patients infected with HCV genotype 2, the pan-genotypic regimen sofosbuvir/velpatasvir (SOF/VEL) was the most cost-effective strategy compared with PEG-RBV, with an ICER of US$5653/QALY. For genotype 3, the combination of sofosbuvir plus daclatasvir (SOF-DCV) was the most cost-effective approach, with an ICER of US$3314/QALY. All DAA regimens for genotype 6 were cost-saving, and sofosbuvir plus ribavirin (SOF-RBV) was the optimal regimen. One-way sensitivity analysis demonstrated that the ICERs were most sensitive to the utility values, discount rate and drug costs. Probabilistic sensitivity analysis indicated that using a threshold equal to one time the gross domestic product (GDP) per capita in China (US$9769/QALY, 2018), the probability of SOF/VEL, SOF-DCV and SOF-RBV being cost-effective was 58%, 83% and 71% for genotype 2, 3 and 6, respectively. Threshold analysis showed that the price of DAAs should be reduced by some degree to achieve better affordability. Conclusions DAAs were cost-effective compared with traditional treatments. A reasonable reduction in the price of DAAs will increase drug affordability and is of great significance as a global strategy to eradicate viral hepatitis.

[PMID: 33051950 PMCID: PMC7821258 DOI: 10.1111/jvh.13422] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Revised: 09/07/2020] [Accepted: 09/28/2020] [Indexed: 12/13/2022]
Abstract
Despite the availability of effective direct-acting antiviral (DAA) treatments for Hepatitis C virus (HCV) infection, many people remain undiagnosed and untreated. We assessed the cost-effectiveness of a Médecins Sans Frontières (MSF) HCV screening and treatment programme within a primary health clinic in Karachi, Pakistan. A health state transition Markov model was developed to estimate the cost-effectiveness of the MSF programme. Programme cost and outcome data were analysed retrospectively. The incremental cost-effectiveness ratio (ICER) was calculated in terms of incremental cost (2016 US$) per disability-adjusted life year (DALY) averted from the provider's perspective over a lifetime horizon. The robustness of the model was evaluated using deterministic and probabilistic sensitivity analyses (PSA). The ICER for implementing testing and treatment compared to no programme was US$450/DALY averted, with 100% of PSA runs falling below the per capita Gross Domestic Product threshold for cost-effective interventions for Pakistan (US$1,422). The ICER increased to US$532/DALY averted assuming national HCV seroprevalence (5.5% versus 33% observed in the intervention). If the cost of liver disease care was included (adapted from resource use data from Cambodia which has similar GDP to Pakistan), the ICER dropped to US$148/DALY, while it became cost-saving if a recently negotiated reduced drug cost of $75/treatment course was assumed (versus $282 in base-case) in addition to cost of liver disease care. In conclusion, screening and DAA treatment for HCV infection are expected to be highly cost-effective in Pakistan, supporting the expansion of similar screening and treatment programmes across Pakistan.

Dig Dis Sci 2020; 65:3159-3174. [PMID: 31938995 PMCID: PMC7358122 DOI: 10.1007/s10620-019-06037-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Accepted: 12/30/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND Despite the high efficacy and safety associated with direct-acting antivirals (DAAs), access to HCV treatment has been frequently restricted because of the high DAA drug costs. OBJECTIVES To (1) compare HCV treatment initiation rates between HCV monoinfected and HCV/HIV coinfected patients before (pre-DAA period) and after (post-DAA period) all-oral DAAs became available; and to (2) estimate the HCV treatment costs for payers and patients. RESEARCH DESIGN AND METHODS A retrospective analysis of the MarketScan® Databases (2009-2016) was conducted for newly diagnosed HCV patients. Multivariable logistic regression was used to estimate the odds ratio (OR) of initiating HCV treatments during the pre-DAA and post-DAA periods. Kruskal-Wallis test was used to compare drug costs for dual, triple and all-oral therapies. RESULTS A total of 15,063 HCV patients [382 (2.5%) HIV coinfected] in the pre-DAA period and 14,896 [429 (2.9%) HIV coinfected] in the post-DAA period were included. HCV/HIV coinfected patients had lower odds of HCV treatment uptake compared to HCV monoinfected patients during the pre-DAA period [OR, 0.59; 95% confidence interval (CI), 0.45-0.78], but no significant difference in odds of HCV treatment uptake was observed during the post-DAA period (OR, 1.08; 95% CI, 0.87-1.33). From 2009 to 2016, average payers' treatment costs (dual, $20,820; all-oral DAAs, $99,661; p < 0.001) as well as average patients' copayments (dual, $593; all-oral DAAs $933; p < 0.001) increased significantly. CONCLUSIONS HCV treatment initiation rates increased, especially among HCV/HIV coinfected patients, from the pre-DAA to the post-DAA period. However, payers' expenditures per course of therapy saw an almost fivefold increase and patients' copayments increased by 55%.

Abstract
The United Kingdom is committed to eliminating hepatitis C virus (HCV) infection by 2025. The prison estate provides an opportunity to identify and treat HCV-positive individuals in a high-prevalence environment. We designed and implemented a pathway of care within a London prison to diagnose, stratify and link HCV-positive prisoners into care. This study was a two-phase case study of a HCV care pathway. New arrivals to the prison were offered blood-borne virus screening with dried blood spot testing at their secondary health check. Those with active infection completed disease stratification tests and were reviewed at a weekly hospital-based multidisciplinary team meeting to determine management. In Phase-2, the pathway was redesigned to improve testing and the referral of HCV-positive prisoners into treatment. Over the 30-month evaluation period, 12,946 people were received in the prison. During Phase-1, 19.6% of new arrivals completed blood-borne virus testing, with 7.3% identified as HCV-positive. Just 8.3% of HCV-positive individuals were treated or referred for treatment in Phase-1. During Phase-2, 30% of new receptions completed BBV testing and 3.9% were identified as HCV-positive. Linkage into care was improved, with 38.9% treated or referred during the second phase. Poor access to testing and referral to treatment limit the effectiveness of care provision for prisoners with HCV. Elimination of HCV in prisons requires local service configuration to ensure high uptake of testing, with all HCV-positive cases then offered treatment during custody or referral on to treatment after release.

Abstract
Background: Injectable interferon-based therapies have been used to treat hepatitis C virus (HCV) infection since 1991. International guidelines have now moved away from interferon-based therapy towards direct-acting antiviral (DAA) tablet regimens, because of their superior efficacy, excellent side-effect profiles, and ease of administration. Initially DAA drugs were prohibitively expensive for most healthcare systems. Access is now improving through the procurement of low-cost, generic DAAs acquired through voluntary licenses. However, HCV treatment costs vary widely, and many countries are struggling with DAA treatment scale-up. This is not helped by the limited cost data and economic evaluations from low- and middle-income countries to support HCV policy decisions. We conducted a detailed analysis of the costs of treating chronic HCV infection with interferon-based therapy in Vietnam. Understanding these costs is important for performing necessary economic evaluations of novel treatment strategies. Methods: We conducted an analysis of the direct medical costs of treating HCV infection with interferon alpha (IFN) and pegylated-interferon alpha (Peg-IFN), in combination with ribavirin, from the health sector perspective at the Hospital for Tropical Diseases, Ho Chi Minh City, Vietnam, in 2017. Results: The total cost of the IFN treatment regimen was estimated to range between US$1,120 and US$1,962. The total cost of the Peg-IFN treatment regimen was between US$2,156 and US$5,887. Drug expenses were the biggest contributor to the total treatment cost (54-89%) and were much higher for the Peg-IFN regimen. Conclusions: We found that treating HCV with IFN or Peg-IFN resulted in significant direct medical costs. Of concern, we found that all patients incurred substantial out-of-pocket costs, including those receiving the maximum level of support from the national health insurance programme. This cost data highlights the potential savings and importance of increased access to generic DAAs in low- and middle-income countries and will be useful within future economic evaluations.

Cost-Utility Analysis of Direct-Acting Antivirals for Treatment of Chronic Hepatitis C Genotype 1 and 6 in Vietnam. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2020; 23:1180-1190. [PMID: 32940236 PMCID: PMC7491253 DOI: 10.1016/j.jval.2020.03.018] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Revised: 02/05/2020] [Accepted: 03/23/2020] [Indexed: 05/12/2023]
Abstract
OBJECTIVE Very few cost-utility analyses have either evaluated direct-acting antivirals (DAAs) on hepatitis C virus (HCV) genotype 6 patients or undertaken societal perspective. Recently, DAAs have been introduced into the Vietnamese health insurance drug list for chronic hepatitis C (CHC) treatment without empirical cost-effectiveness evidence. This study was conducted to generate these data on DAAs among CHC patients with genotypes 1 and 6 in Vietnam. METHODS A hybrid decision-tree and Markov model was employed to compare costs and quality-adjusted life-years (QALYs) of available DAAs, including (1) sofosbuvir/ledipasvir, (2) sofosbuvir/velpatasvir, and (3) sofosbuvir plus daclatasvir, with pegylated-interferon plus ribavirin (PR). Primary data collection was conducted in Vietnam to identify costs and utility values. Incremental cost-effectiveness ratios were estimated from societal and payer perspectives. Uncertainty and scenario analyses and value of information analyses were performed. RESULTS All DAAs were cost-saving as compared with PR in CHC patients with genotypes 1 and 6 in Vietnam, and sofosbuvir/velpatasvir was the most cost-saving regimen, from both societal and payer perspectives. From the societal perspective, DAAs were associated with the increment of quality-adjusted life-years by 1.33 to 1.35 and decrement of costs by $6519 to $7246. Uncertainty and scenario analyses confirmed the robustness of base-case results, whereas the value of information analyses suggested the need for further research on relative treatment efficacies among DAA regimens. CONCLUSIONS Allocating resources for DAA treatment for HCV genotype 1 and 6 is surely a rewarding public health investment in Vietnam. It is recommended that the government rapidly scale up treatment and enable financial accessibility for HCV patients.

Abstract
Objective Patient-reported outcomes (PROs) are important measures of the quality of life (QOL) and symptoms in patients with hepatitis C virus (HCV). We evaluated the PROs at the beginning of direct-acting antiviral (DAA) treatment and three years later. A low QOL in patients with chronic liver disease suggested a low muscle mass. We compared the relationship between the QOL and muscle mass. Methods DAAs were administered to 100 patients with HCV infection. The PROs included the cirrhosis-related symptom score (CSS), presence of restless legs syndrome, Pittsburg sleep quality index (PSQI) to evaluate sleep disturbance, SF-36 to measure the QOL, and calculated body muscle mass (CBMM) measured at the beginning of treatment and three years later. Computed tomography (CT) was used to screen 82 patients for hepatocellular carcinoma at the beginning of treatment and three years later. Cross-sectional CT images of the third lumbar vertebrae were analyzed to evaluate the body composition. Results The general health perception (GHN) of SF-36 was better at three years after DAA administration than at the beginning. Changes in the GHN (dGHN) were related to an improved sleep quality on the PSQI and CSS and increased CBMM. The dGHN was positively related to changes in the skeletal muscle. The sleep quality, sleep latency, fatigue, and abdominal fullness were related to dGHN. Conclusion The QOL is related to sleep disturbance and several other symptoms. Furthermore, in patients with an increased muscle volume after DAA treatment, increased muscle mass is associated with an improvement in the QOL.

Abstract
BACKGROUND The Sustainable Development Goals (SDGs), adopted by all United Nations (UN) member states in 2015, established a set of bold and ambitious health-related targets to achieve by 2030. Understanding China's progress toward these targets is critical to improving population health for its 1.4 billion people. METHODS AND FINDINGS We used estimates from the Global Burden of Disease (GBD) Study 2016, national surveys and surveillance data from China, and qualitative data. Twenty-eight of the 37 indicators included in the GBD Study 2016 were analyzed. We developed an attainment index of health-related SDGs, a scale of 0-100 based on the values of indicators. The projection model is adjusted based on the one developed by the GBD Study 2016 SDG collaborators. We found that China has achieved several health-related SDG targets, including decreasing neonatal and under-5 mortality rates and the maternal mortality ratios and reducing wasting and stunting for children. However, China may only achieve 12 out of the 28 health-related SDG targets by 2030. The number of target indicators achieved varies among provinces and municipalities. In 2016, among the seven measured health domains, China performed best in child nutrition and maternal and child health and reproductive health, with the attainment index scores of 93.0 and 91.8, respectively, followed by noncommunicable diseases (NCDs) (69.4), road injuries (63.6), infectious diseases (63.0), environmental health (62.9), and universal health coverage (UHC) (54.4). There are daunting challenges to achieve the targets for child overweight, infectious diseases, NCD risk factors, and environmental exposure factors. China will also have a formidable challenge in achieving UHC, particularly in ensuring access to essential healthcare for all and providing adequate financial protection. The attainment index of child nutrition is projected to drop to 80.5 by 2025 because of worsening child overweight. The index of NCD risk factors is projected to drop to 38.8 by 2025. Regional disparities are substantial, with eastern provinces generally performing better than central and western provinces. Sex disparities are clear, with men at higher risk of excess mortality than women. The primary limitations of this study are the limited data availability and quality for several indicators and the adoption of "business-as-usual" projection methods. CONCLUSION The study found that China has made good progress in improving population health, but challenges lie ahead. China has substantially improved the health of children and women and will continue to make good progress, although geographic disparities remain a great challenge. Meanwhile, China faced challenges in NCDs, mental health, and some infectious diseases. Poor control of health risk factors and worsening environmental threats have posed difficulties in further health improvement. Meanwhile, an inefficient health system is a barrier to tackling these challenges among such a rapidly aging population. The eastern provinces are predicted to perform better than the central and western provinces, and women are predicted to be more likely than men to achieve these targets by 2030. In order to make good progress, China must take a series of concerted actions, including more investments in public goods and services for health and redressing the intracountry inequities.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection is highly prevalent among people who inject drugs but is often undiagnosed. The treatment paradigm for HCV patients has been changing since the availability of direct-acting antiviral (DAA) treatment. We aimed to evaluate the change in treatment paradigm of people who previously injected drugs (ex-PWID) in Hong Kong before and after the availability of DAA. METHOD Consecutive ex-PWID referred from various nongovernmental organizations attended education talks at rehabilitation centers and received point-of-care rapid test for HCV antibody (anti-HCV) at the same session. Subjects tested positive for anti-HCV were invited to undergo further assessment. Afterwards, the patients were referred to the regional hospitals for follow-up and/or treatment. RESULTS Three hundred sixty-five ex-PWID received HCV rapid test; 268 (73.4%) were found to be anti-HCV positive. Among these 268 HCV-positive ex-PWID, 234 (87.3%) attended the assessment session (mean age 52 years, 90.2% male, 45.5% genotype 1b, 41.1% genotype 6a, and median liver stiffness 5.9 kPa); 187 (69.8%) attended follow-up visits at regional hospitals. Seventy-one patients received antiviral treatment for HCV; 69 first received peginterferon and ribavirin (PegIFN/RBV), whereas 10 patients (eight PegIFN/RBV-treated patients) received DAA treatment. Fifty-two patients achieved sustained virologic response at 12 or 24 weeks. Treatment uptake rates of PegIFN/RBV and DAA treatment in the pre-DAA versus post-DAA era were 22.3% versus 48.5% and 0% versus 15.6%, respectively. CONCLUSIONS Targeted screening in ex-PWID is effective in identifying patients with HCV infection in the community. To improve treatment uptake, further improvements in the referral system and treatment regimens are needed.

Abstract
Aim: Hepatitis C virus (HCV) is the leading cause of hepatocellular carcinoma (HCC) in the United States. Achieving sustained viral response with interferon (IFN) treatment reduces the risk from 3%-5% to 0.5%-1% annually. Several studies reported unexpectedly high rates of HCC after treatment with direct-acting antivirals (DAAs). The aim of our study was to compare HCC rates in DAA-, IFN-treated and untreated populations. Methods: A literature search was conducted using ScienceDirect, Ovid®, Web of Science and MEDLINE through January 2019. Studies were included if they measured rates of de novo or recurrent HCC (following curative treatment) in HCV-infected persons. We included 138 studies (n = 177,512). Simple pooling of data and meta-analysis were performed, using the random effects method. Results: Mean age was higher in the DAA-treated vs. IFN-treated group (58.4 years vs. 52.6 years; P = 0.0073), as were diabetes prevalence (34.5% vs. 11.7%; P ≤ 0.001) and incident cirrhosis (47.8% vs. 34.2%, P = 0.0017). The incidence rate of de novo HCC was 2.01/100 person-years (py) (95%CI: 1.38, 2.67) in the DAA group and 1.45/100py (95%CI: 0.98, 1.94) in the IFN-treated group. HCC recurred at 16.76/100py (95%CI: 10.75, 22.91) in the DAA-treated group vs. 20.04/100py (95%CI: 2.58, 45.21) after IFN. After adjusting for factors such as age and cirrhosis, the hazard ratio was 0.58 (95%CI: 0.20, 1.07) for HCC occurrence and 0.59 (95%CI: 0.24, 1.03) for HCC recurrence after DAA treatment compared to IFN-based treatment. Conclusion: We did not find evidence for increased rates of HCC in DAA-treated compared with IFN-treated patients. Compared to those treated with IFN, older patients with additional risk factors for HCC were treated with DAAs. This imbalance appears to explain the higher numerical incidence of HCC among DAA-treated patients.

Abstract
OBJECTIVES Given the goal of hepatitis C virus elimination by 2030, World Health Organization guidelines recommend treatment of chronic hepatitis C (CHC) with pan-genotypic direct-acting antivirals, such as sofosbuvir/velpatasvir (SOF/VEL), SOF/VEL/voxilaprevir (VOX) or glecaprevir/pibrentasvir (GLE/PIB). The study evaluated the cost-effectiveness of pan-genotypic regimens in initial (SOF/VEL or GLE/PIB) and re-treatment (SOF/VEL/VOX or GLE/PIB+SOF+ribavirin (RBV)) of CHC. METHODS A Markov state-transition model projected lifetime CHC health and economic outcomes from the US payer perspective. Model inputs were sourced from clinical trials or published literature and validated by hepatologists. Model outcomes included numbers of advanced liver disease events, life-years and quality-adjusted life-years (QALYs) gained, and total lifetime costs. One-way sensitivity analyses were performed on model results. RESULTS SOF/VEL followed by SOF/VEL/VOX resulted in comparable cure rates to the GLE/PIB treatment pathway (99.94% vs. 99.93%, respectively). SOF-based regimens provided similar QALYs at a lower lifetime cost versus a GLE/PIB treatment pathway ($30,749 vs. $36,255), resulting in cost savings of $5,506 per patient. Results were robust in sensitivity analyses. CONCLUSION SOF/VEL followed by SOF/VEL/VOX leads to comparable cure rates in the overall CHC population relative to the GLE/PIB treatment pathway. Based on wholesale acquisition prices, the SOF/VEL treatment pathway led to lower lifetime costs.

Abstract
AIM Sofosbuvir is a key agent for HCV treatment. It is not recommended for patients with chronic kidney disease (CKD) and estimated glomerular filtration rate (eGFR) <30 mL/min. We report real-life experience of treating a cohort of CKD patients with eGFR <30 mL/min using daclatasvir and half-daily dose of sofosbuvir. METHODS Adults patients who (i) had eGFR<30 mL/min and detectable HCV RNA and (ii) were treated with interferon and ribavirin free, DAA based regimens were included. All patients were treated with daily doses of daclatasvir 60 mg and sofosbuvir 200 mg. The planned duration of treatment was 12 weeks, except for 24 weeks in those with either clinical evidence of cirrhosis or on immunosuppressive drugs. The end-points of the study were: (i) 12 weeks of follow-up after treatment completion, (ii) treatment discontinuation, or (iii) death or loss to follow-up. RESULTS Thirty-six (88%) among 41 included patients (median [range] age: 48 [19-75] years; 25 [61%] male; genotype 1/3/4 were 17/ 22/2; cirrhosis 5) completed the treatment, two discontinued and three died during treatment. On an intention-to-treat basis, HCV RNA were undetectable at 4 weeks of treatment, treatment completion and after 12 weeks of follow-up in 40/41 (97.6%), 37/41 (90.2%) and 37/41 (90.2%), respectively. None of the patients had a relapse. CONCLUSIONS Daclatasvir and half-daily dose of sofosbuvir was effective against genotype 1 and 3 HCV infection in patients with eGFR <30 mL/min. This combination could be a pangenotypic treatment option for such patients.

Abstract
OBJECTIVES Oral direct-acting antivirals (DAAs) for hepatitis C virus (HCV) have dramatically changed the treatment paradigm. Our aim was to project temporal trends in HCV diagnosis, treatment and disease burden in France, Germany, Italy, Spain and the UK. DESIGN A mathematical simulation model of natural history of HCV infection. PARTICIPANTS HCV-infected patients defined based on country-specific age, fibrosis and genotype distributions. INTERVENTIONS HCV screening practice and availability of different waves of DAA treatment in each country. OUTCOME MEASURES Temporal trends in the number of patients who achieve sustained virological response (SVR), fail treatment (by drug regimen) and develop advanced sequelae from 2014 to 2030 in each country. RESULTS We projected that 1 324 000 individuals would receive treatment from 2014 to 2030 in the five European countries and 12 000-37 000 of them would fail to achieve SVR. By 2021, the number of individuals cured of HCV would supersede the number of actively infected individuals in France, Germany, Spain and the UK. Under status quo, the diagnosis rate would reach between 65% and 75% and treatment coverage between 65% and 74% by 2030 in these countries. The number of patients who fail treatment would decrease over time, with the majority of those who fail treatment having been exposed to non-structural protein 5A inhibitors. CONCLUSIONS In the era of DAAs, the number of people with HCV who achieved a cure will exceed the number of viraemic patients, but many patients will remain undiagnosed, untreated, fail multiple treatments and develop advanced sequelae. Scaling-up screening and treatment capacity, and timely and effective retreatment are needed to avail the full benefits of DAAs and to meet HCV elimination targets set by WHO.

Cost-effectiveness and budgetary impact of HCV treatment with direct-acting antivirals in India including the risk of reinfection. PLoS One 2019; 14:e0217964.

Abstract
BACKGROUND HCV direct-acting antivirals (DAAs) are produced in India at low cost. However, concerns surrounding reinfection and budgetary impact limit treatment scale-up in India. We evaluate the cost-effectiveness and budgetary impact of HCV treatment in India, including reinfection. METHODS A closed cohort Markov model of HCV disease progression, treatment, and reinfection was parameterized. We compared treatment by fibrosis stage (F2-F4 or F0-F4) to no treatment from a health care payer perspective. Costs (2017 USD$, based on India-specific data) and health utilities (in quality-adjusted life years, QALYs) were attached to each health state. We assumed DAAs with 90% sustained viral response at $900/treatment and 1%/year reinfection, varied in the sensitivity analysis from 0.1-15%. We deemed the intervention cost-effective if the incremental cost-effectiveness ratio (ICER) fell below India's per capita GDP ($1,709). We assessed the budgetary impact of treating all diagnosed individuals. RESULTS HCV treatment for diagnosed F2-F4 individuals was cost-saving (net costs -$2,881 and net QALYs 3.18/person treated; negative ICER) compared to no treatment. HCV treatment remained cost-saving with reinfection rates of 15%/year. Treating all diagnosed individuals was likely cost-effective compared to delay until F2 (mean ICER $1,586/QALY gained, 67% of simulations falling under the $1,709 threshold) with 1%/year reinfection. For all scenarios, annual retesting for reinfection was more cost-effective than the current policy (one-time retest). Treating all diagnosed individuals and reinfections results in net costs of $445-1,334 million over 5 years (<0.25% of total health care expenditure over 5 years), and cost-savings within 14 years. CONCLUSIONS HCV treatment was highly cost-effective in India, despite reinfection. Annual retesting for reinfection was cost-effective, supporting a policy change towards more frequent retesting. A comprehensive HCV treatment scale-up plan is warranted in India.

Abstract
Background Direct-acting antivirals (DAAs) are effective in patients aged ≥65 years. However, little is known about the effects of DAAs on survival, liver decompensation and development of hepatocellular carcinoma (HCC). Objective To compare the incidence of liver-related events and mortality between patients aged ≥65 and <65 years. Methods Prospective study comparing patients aged ≥65 and <65 years treated with DAAs. The incidence of liver-related events and mortality, and HCC was compared between age groups. Results Five hundred patients (120 aged ≥65 and 380 aged <65 years) were included. The incidence of liver-related events was 2.62 per 100 patient-years (py) in older and 1.41/100 py in younger patients. All-cause mortality was 3.89 and 1.27/100 py in older and younger patients, respectively. The respective liver-related mortality rates were 1.12 and 0.31/100 py. In patients with cirrhosis (stage F4), all-cause mortality (P = 0.283) and liver-related mortality (P = 0.254) did not differ between groups. All five liver-related deaths were related to multifocal HCC. The incidence of HCC was 1.91 and 1.43 per 100 py in the older and younger groups, respectively (P = 0.747). The diagnosis of HCC was 8 months after the end of treatment. Conclusions The incidence of liver-related events and liver-related mortality was low in older people treated with DAAs and was similar to that in younger patients. The extra mortality in people aged ≥65 years treated with DAAs seems to be secondary to non-liver-related causes. These results support the utilization of DAAs in patients aged ≥65 years.

Abstract
OBJECTIVES To estimate the impact of cures for chronic hepatitis C (CHC) infection on organ donation in the United Kingdom. Curing CHC infection reduces the need for liver transplants and enables cured individuals to donate organs of all types. METHODS We adapted a double-queuing model of organ allocation to estimate the effects of CHC infection cures on liver, lung, heart, and kidney transplants in the United Kingdom. We assumed that cured individuals would donate organs at similar rates as the general population and no longer require liver transplants because of CHC infection. We estimated how curing CHC infection influences waitlist lengths for each organ and the annual net present value to society on the basis of quality-adjusted life-years gained through additional transplants under opt-in and opt-out organ donation policies. RESULTS Curing CHC generates the most value for patients on the liver waitlist, because it increases the number of transplantable livers and reduces the need for transplants. Under the current opt-in policy, liver waitlist length falls by 24%, generating £34.3 million of annual net present value. Growth in the number of uninfected lungs, hearts, and kidneys generates an additional £19.2 million annually, with £18.7 million from kidneys. Implementing the opt-out policy, liver waitlist length would decrease by 75%, implying that treating CHC eliminates one-third of the excess liver waitlist due to an opt-in policy. CONCLUSIONS Treating CHC has large positive spillovers to uninfected individuals by reducing the need for liver transplants and allowing cured individuals to donate organs. These spillovers have not been included in traditional value assessments of CHC treatment.

Abstract
BACKGROUND Because of the heterogeneity of hepatitis C virus (HCV) distribution of different genotypes, large-scale clinical trials on direct-acting antiviral (DAA) mainly included patients with genotype 1 and genotype 3 infection. Data on the efficacy of direct-acting antiviral agents in patients with chronic genotype 6 HCV infection are limited. METHODS The PubMed, Embase, and the Cochrane Libraries were searched comprehensively. All published clinical trials assessing the efficacy of DAA therapy for patients with chronic genotype 6 HCV infection were included. Sustained virological response (SVR) and rapid virological response (RVR) were pooled. Additional meta-analyses were also performed to compare the efficacy of DAA therapy in HCV-6 versus HCV-1 or HCV-3 patients. RESULTS Seventeen studies met the inclusion criteria and were included in our meta-analysis. The pooled SVR of all single arms was 95% [95% confidence interval (CI): 0.90-0.97]. The pooled RVR of all single arms was 97% (95% CI: 0.95-0.99). The SVR and RVR were both similar between HCV-6 and HCV-1 or HCV-3. Adverse events were common but rarely caused treatment interruption. CONCLUSION Based on the available data, our results indicate that DAA treatment is effective and safe for patients with genotype 6 HCV infection, and the efficacy was similar compared to patients with genotype 1 HCV or genotype 3 HCV infection.

Abstract
BACKGROUND Rotavirus causes morbidity and mortality in children particularly in low-income countries (LICs) and lower-middle-income countries (LMICs). This systematic review and meta-analysis aimed to assess cost-effectiveness of rotavirus vaccine in LICs and LMICs. METHODS Relevant studies were identified from PubMed and Scopus from their inception to January 2019. Studies were eligible if they assessed the cost-effectiveness of rotavirus vaccine in children in LICs and LMICs and reported incremental cost-effectiveness ratios. Risk of bias and quality assessment was assessed based on the Consolidated Health Economic Evaluation Reporting Standard checklist. Incremental net benefits (INBs) were estimated, and meta-analysis based on the DerSimonian and Laird method was applied to pool INBs across studies. RESULTS We identified 1614 studies, of which 28 studies (29 countries) were eligible and conducted using cost-utility analysis in LICs (n = 8) and LMICs (n = 21). The pooled INB was estimated at $62.17 (95% confidence interval, $7.12-$117.21) in LICs, with a highly significant heterogeneity (χ2 = 33.96; df = 6; P < .001; I 2 = 82.3%), whereas the pooled INB in LMICs was $82.46 (95% confidence interval, $54.52-$110.41) with no heterogeneity (χ2 = 8.46; df = 11; P = .67; I 2 = 0%). CONCLUSIONS Rotavirus vaccine would be cost-effective to introduce in LICs and LMICs. These findings could aid decision makers and provide evidence for introduction of rotavirus vaccination.

Economic evaluation of the hepatitis C elimination strategy in Greece in the era of affordable direct-acting antivirals. World J Gastroenterol 2019; 25:1327-1340. [PMID: 30918426 PMCID: PMC6429341 DOI: 10.3748/wjg.v25.i11.1327] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 02/20/2019] [Accepted: 02/23/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Hepatitis C virus (HCV) is a leading cause of worldwide liver-related morbidity and mortality. The World Health Organization released an integrated strategy targeting HCV-elimination by 2030. This study aims to estimate the required interventions to achieve elimination using updated information for direct-acting antiviral (DAA) treatment coverage, to compute the total costs (including indirect/societal costs) of the strategy and to identify whether the elimination strategy is cost-effective/cost-saving in Greece.
AIM To estimate the required interventions and subsequent costs to achieve HCV elimination in Greece.
METHODS A previously validated mathematical model was adapted to the Greek HCV-infected population to compare the outcomes of DAA treatment without the additional implementation of awareness or screening campaigns versus an HCV elimination strategy, which includes a sufficient number of treated patients. We estimated the total costs (direct and indirect costs), the disability-adjusted life years and the incremental cost-effectiveness ratio using two different price scenarios.
RESULTS Without the implementation of awareness or screening campaigns, approximately 20000 patients would be diagnosed and treated with DAAs by 2030. This strategy would result in a 19.6% increase in HCV-related mortality in 2030 compared to 2015. To achieve the elimination goal, 90000 patients need to be treated by 2030. Under the elimination scenario, viremic cases would decrease by 78.8% in 2030 compared to 2015. The cumulative direct costs to eliminate the disease would range from 2.1-2.3 billion euros (€) by 2030, while the indirect costs would be €1.1 billion. The total elimination cost in Greece would range from €3.2-3.4 billion by 2030. The cost per averted disability-adjusted life year is estimated between €10100 and €13380, indicating that the elimination strategy is very cost-effective. Furthermore, HCV elimination strategy would save €560-895 million by 2035.
CONCLUSION Without large screening programs, elimination of HCV cannot be achieved. The HCV elimination strategy is feasible and cost-saving despite the uncertainty of the future cost of DAAs in Greece.

Abstract
BACKGROUND Hepatitis C virus (HCV) genotype 6 (GT6) is predominantly encountered in Southeast Asia and data on GT6 response to direct-acting antiviral (DAA) therapy are relatively limited. AIM To review the epidemiology and virologic outcome of DAA regimens in HCV GT6 patients. METHODS Electronic literature search of PubMed, EMBASE, and The Cochrane Library databases were conducted. RESULTS Hepatitis C virus genotype 6 is the most genetically diverse, has a prevalence of 19.9%-95.6% in HCV infected patients in Southeast Asia and has been associated with a higher risk of HCC in those with cirrhosis. After an extensive literature review, a total of 20 studies were selected to assess study population and treatment outcomes (total of 938 GT6 patients were included); 12 were clinical trials and eight were observational studies. Sustained virologic response at week 12 (SVR 12) following glecaprevir/pibrentasvir (n = 4; 108 patients), ledipasvir/sofosbuvir (n = 8; 427 patients), sofosbuvir/velpatasvir with or without voxilaprevir (n = 5; 171 patients), sofosbuvir/daclatasvir (n = 3; 172 patients) and sofosbuvir with ribavirin (n = 3; 60 patients) was 98%-100%, 64%-100%, 100%, 88%-94% and 100%, respectively. Failure was mostly in those with cirrhosis and prior treatment experience. DAA therapy was well tolerated and with a serious adverse event rate of <5%. CONCLUSIONS Hepatitis C virus genotype 6 is genetically diverse and is highly prevalent in Asia. While SVR rates have been high, cirrhosis and prior treatment experience marginally compromise response to DAAs. Large scale and exclusive studies in HCV genotype 6 prevalent areas are needed, while the current evidence suggests that DAAs are highly effective and safe.

Abstract
An estimated 30% of Americans with hepatitis C virus (HCV) pass through a jail or prison annually. One in 7 incarcerated persons is viremic. Screening and treatment is cost-effective and beneficial to society as a whole. Yet at current (2018) levels of funding for HCV management, prisons are not aggressively seeking cases; few incarcerated persons with HCV actually receive treatment. This article explores barriers to screening for and treating hepatitis C in state prisons, and ways that states may overcome these barriers, such as nominal pricing. While high prices for direct-acting antivirals discourage treatment, potential strategies exist to lower prices.

Abstract
Today, one of the most important global public health challenges is represented by hepatitis C virus (HCV), which imposes relevant costs. Globally speaking, the median cost of HCV-related complications ranges from $280 for an uncomplicated hepatitis to $139,070 for a liver transplantation. There are effective therapies for HCV patients worldwide, which has increased the hope of improving the process of managing and curing these patients. The adherence of patients to the pharmacological treatment and the use of effective drugs in the management of HCV disease are of crucial importance for health policy- and decision-makers. Studies show that, globally, insurance coverage for patients with HCV is not adequate in that still many patients are not covered by insurance programs. This issue as well as the economic conditions of countries are very serious challenges for ensuring an effective treatment. The most important and greatest help currently available to ensure HCV treatment is to implement plans to reduce costs and support patients. Some studies have shown that the expansion of coverage by private payers seems able to generate positive spillover benefits to public insures. Insurers, in addition to maintaining and increasing their own interests, are trying to increase their social status as a sponsor of patients. In conclusion, HCV disease requires serious policies and affordable insurance coverage.

Low hepatitis C prevalence in Belgium: implications for treatment reimbursement and scale up. BMC Public Health 2019; 19:39.

Abstract
Background Prevalence data of chronic hepatitis C virus (HCV) infection are needed to estimate the budgetary impact of reimbursement of direct-acting antivirals (DAAs). In Belgium, the restricted reimbursement criteria are mainly guided by regional seroprevalence estimates of 0.87% from 1993 to 1994. In this first Belgian nationwide HCV prevalence study, we set out to update the seroprevalence and prevalence of chronic HCV infection estimates in the Belgian general population in order to guide decisions on DAA reimbursement. Methods Residual sera were collected through clinical laboratories. We collected data on age, sex and district. HCV antibody status was determined with ELISA and confirmed with a line-immunoassay (LIA). In specimens with undetermined or positive LIA result, HCV viral load was measured. Specimens were classified seronegative, seropositive with resolved infection, indicative of chronic infection and with undetermined HCV status according to the test outcomes. Results were standardized for age, sex and population per district, and adjusted for clustered sampling. Results In total 3209 specimens, collected by 28 laboratories, were tested. HCV seropositivity in the Belgian general population was estimated to be 0.22% (95% CI: 0.09–0.54%), and prevalence of chronic HCV infection 0.12% (95% CI: 0.03–0.41). In individuals of 20 years and older, these estimates were 0.26% (95% CI: 0.10–0.64%) and 0.13% (95% CI: 0.04–0.43), respectively. Of the total estimated number of HCV seropositive individuals in Belgium, 66% were between 50 and 69 years old. Conclusions Prevalence of HCV seropositivity and chronic infection in the Belgian general population were low and comparable to many surrounding countries. These adjusted prevalences can help estimate the cost of reimbursement of DAAs and invite Belgian policy makers to accelerate the scaling up of reimbursement, giving all chronically infected HCV patients a more timely access to treatment.

Abstract
Direct-acting antiviral (DAA) regimens are safe and effective at eradicating hepatitis C virus (HCV) infection. Unfortunately, DAAs remain expensive, so treatment of all HCV-infected patients would substantially affect health care costs. It is therefore important to continue to assess the hepatic and extrahepatic benefits of a DAA-induced sustained virologic response (SVR). A DAA-induced SVR reduces a patient's risk of cirrhosis and hepatocellular carcinoma and extrahepatic manifestations of HCV infection; there are also data to indicate that an SVR can reduce mortality. SVR is a relevant clinical end point, but further analyses are required to confirm its importance among diverse HCV-infected populations and to document the public health benefits of HCV elimination at the population level. We review the evidence for the benefits associated with SVRs in different clinical settings and challenges to data collection.

Clinical effectiveness of pharmacy-led versus conventionally delivered antiviral treatment for hepatitis C in patients receiving opioid substitution therapy: a study protocol for a pragmatic cluster randomised trial. BMJ Open 2018; 8:e021443.

Abstract
INTRODUCTION Hepatitis C virus (HCV) infection affects 0.7% of the general population, and up to 40% of people prescribed opioid substitution therapy (OST) in Scotland. In conventional care, less than 10% of OST users are tested for HCV and less than 25% of these initiate treatment. Community pharmacists see this group frequently to provide OST supervision. This study examines whether a pharmacist-led 'test & treat' pathway increases cure rates for HCV. METHODS AND ANALYSIS This protocol describes a cluster-randomised trial where 60 community pharmacies provide either conventional or pharmacy-led care. All pharmacies offer dried blood spot testing (DBST) for HCV. Participants have attended the pharmacy for OST for 3 months; are positive for HCV genotype 1 or 3; are not co-infected with HIV and/or hepatitis B; have no decompensated liver disease; are not pregnant. For conventional care, pharmacists refer HCV-positive participants to a local centre for assessment. In the pharmacy-led arm, pharmacists assess participants themselves in the pharmacy. Drug prescribing is by nurse prescribers (conventional arm) or pharmacist prescribers (pharmacy-led arm). Treatment in both arms is delivered as daily modified directly observed therapy in a pharmacy. Primary trial outcome is number of sustained virological responses at 12 weeks after treatment completion. Secondary trial outcomes are number of tests taken; treatment uptake; completion; adherence; re-infection. An economic evaluation will assess potential cost-effectiveness. Qualitative research interviews with clients and health professionals assess acceptability of a pharmacist-led pathway. ETHICS AND DISSEMINATION This protocol has been ethically approved by the East of Scotland Research Ethics Committee 2 (15/ES/0086) and complies with the Declaration of Helsinki and principles of Good Clinical Practice. Caldicott guardian approval was given on 16 December 2016 to allow NHS Tayside to pass information to the cluster community pharmacies about the HCV test status of patients that they are seeing to provide OST supervision. NHS R&D approvals have been obtained from each health board taking part in the study. Informed consent is obtained before study enrolment and only anonymised data are stored in a secured database, enabling an audit trail. Results will be submitted to international peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBER NCT02706223; Pre-results.

Abstract
High prices of second-generation direct-acting antivirals (DAAs) in the treatment of chronic hepatitis C virus (HCV) patients led to reimbursement decisions based on cost per quality-adjusted life year (QALY). Areas covered: We performed a systematic review of cost-utility analyses (CUA) comparing interventions with second-generation DAA therapies with no treatment, and with previous therapies for chronic HCV patients until July 2017. A total of 36 studies were included: 30 studies from the perspective of the healthcare payer, 3 from the societal perspective, and 3 did not report the perspective. For genotype 1, the highest number of ICER comparison corresponds to sofosbuvir (SOF) triple therapy and SOF-based combinations which reported a cost per QALY systematically ranging from negative to lower than US$100,000 when compared with no treatment or dual therapy or Simeprevir triple therapy. Expert commentary: Selected studies may be overestimating the true cost per QALY of second-generation DAAs in the treatment of HCV, mainly because of neglecting non-healthcare costs, using official list prices which are higher than actual transaction prices and not adopting the long run drug price in a dynamic approach. In addition, the impact of important price reductions of several DAAs in recent years on cost per QALY should be considered.

Abstract
Treatment of hepatitis C virus (HCV) infection has been revolutionized with the introduction of pangenotypic, interferon- and ribavirin-free regimens associated with high cure rates and a low side effect profile. Additionally, there is evidence that HCV cure reduces HCV complications, improves patient-reported outcomes and is cost-saving in most western countries in the long term. This is a review of the comprehensive burden of HCV and the value of eliminating HCV infection. With the introduction of the interferon-free all-oral, once a day pill treatment regimen for the cure of HCV, the potential to eliminate HCV by 2030 has become a possibility for some regions of the world. Nevertheless, there are barriers to screening, linkage to care, and treatment in many countries that must be overcome in order to reach this goal. In conclusion, globally, work must continue to ensure national policies are in place to support screening, linkage to care and affordable treatment in order to eliminate HCV.

Abstract
Direct-acting antiviral medications (DAAs) have revolutionized care for hepatitis C positive (HCV+) liver (LT) and kidney (KT) transplant recipients. Scientific Registry of Transplant Recipients registry data were integrated with national pharmaceutical claims (2007-2016) to identify HCV treatments before January 2014 (pre-DAA) and after (post-DAA), stratified by donor (D) and recipient (R) serostatus and payer. Pre-DAA, 18% of HCV+ LT recipients were treated within 3 years and without differences by donor serostatus or payer. Post-DAA, only 6% of D-/R+ recipients, 19.8% of D+/R+ recipients with public insurance, and 11.3% with private insurance were treated within 3 years (P < .0001). LT recipients treated for HCV pre-DAA experienced higher rates of graft loss (adjusted hazard ratio [aHR] 1.34 1.852.10 , P < .0001) and death (aHR 1.47 1.681.91 , P < .0001). Post-DAA, HCV treatment was not associated with death (aHR 0.34 0.671.32 , P = .25) or graft failure (aHR 0.32 0.641.26 , P = .20) in D+R+ LT recipients. Treatment increased in D+R+ KT recipients (5.5% pre-DAA vs 12.9% post-DAA), but did not differ by payer status. DAAs reduced the risk of death after D+/R+ KT by 57% (0.19 0.430.95 , P = .04) and graft loss by 46% (0.27 0.541.07 , P = .08). HCV treatment with DAAs appears to improve HCV+ LT and KT outcomes; however, access to these medications appears limited in both LT and KT recipients.

Aliment Pharmacol Ther 2018; 47:1023-1031. [PMID: 29377245 PMCID: PMC5842132 DOI: 10.1111/apt.14527] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2017] [Revised: 11/28/2017] [Accepted: 12/31/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND The introduction of oral direct-acting antivirals (DAAs) has dramatically changed the landscape of HCV treatment. However, a small percentage of patients fail to achieve sustained virologic response (SVR). Understanding the number of people who fail on DAAs and require re-treatment is important for budget impact and disease burden projections. AIM To quantify the number of HCV patients who fail to achieve SVR on oral DAAs (NS5A vs. non-NS5A) and require re-treatment. METHODS We used a mathematical model to simulate clinical management of HCV in the USA, which included the implementation of HCV screening, treatment, and disease progression. We simulated different waves of DAA treatment and used real-world data to extract SVR rates and market shares of available therapies. RESULTS Our model projected that the number of people living without viraemia (i.e. cured) would increase from 0.70 million in 2014 to 1.78 million by 2020. Between 2014 and 2020, 1.50 million people would receive treatment with DAAs, of whom 124 000 (8.3%) are projected to fail to achieve SVR. Among those treatment failures, 66 600 (53.7%) patients would fail treatment with NS5A inhibitors and 69 600 (56.1%) would have cirrhosis. During the same period, 34 200 people would progress to decompensated cirrhosis and 27 300 would develop hepatocellular carcinoma after failing to achieve SVR. CONCLUSIONS Even in the era of highly effective DAAs, a significant number of patients will fail to achieve SVR and will require re-treatment options. Timely and effective re-treatment is essential to prevent the long-term sequelae of HCV.

Abstract
Hepatitis C virus (HCV) infection is a major public health problem in the European Union (EU). An estimated 5.6 million Europeans are chronically infected with a wide range of variation in prevalence across European Union countries. Although HCV continues to spread as a largely "silent pandemic," its elimination is made possible through the availability of the new antiviral drugs and the implementation of prevention practices. On 17 February 2016, the Hepatitis B & C Public Policy Association held the first EU HCV Policy Summit in Brussels. This summit was an historic event as it was the first high-level conference focusing on the elimination of HCV at the European Union level. The meeting brought together the main stakeholders in the field of HCV: clinicians, patient advocacy groups, representatives of key institutions and regional bodies from across European Union; it served as a platform for one of the most significant disease elimination campaigns in Europe and culminated in the presentation of the HCV Elimination Manifesto, calling for the elimination of HCV in Europe by 2030. The launch of the Elimination Manifesto provides a starting point for action in order to make HCV and its elimination in Europe an explicit public health priority, to ensure that patients, civil society groups and other relevant stakeholders will be directly involved in developing and implementing HCV elimination strategies, to pay particular attention to the links between hepatitis C and social marginalization and to introduce a European Hepatitis Awareness Week.

Safety and efficacy of sofosbuvir-based treatment of acute hepatitis C in end-stage renal disease patients undergoing haemodialysis. Aliment Pharmacol Ther 2018; 47:526-532. [PMID: 29250808 DOI: 10.1111/apt.14429] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2017] [Revised: 07/24/2017] [Accepted: 10/31/2017] [Indexed: 12/27/2022]
Abstract
BACKGROUND Hepatitis C virus (HCV) infection in patients undergoing haemodialysis is prevalent and aggressive. The treatment of chronic hepatitis C has been revolutionised by the advent of direct-acting antivirals (DAAs). However, the safety, efficacy, and tolerance of DAAs in the treatment of acute HCV infection in patients with end-stage renal disease who are on haemodialysis are unknown. AIM To evaluate the safety and efficacy of sofosbuvir plus daclatasvir in this specific, difficult-to-treat population. METHODS We conducted a prospective and observational study of end-stage renal disease patients who were undergoing haemodialysis and were acutely infected with HCV. Patients received a half dose of sofosbuvir (200 mg) and a full dose of daclatasvir (60 mg) daily. The primary endpoint was the proportion of patients with sustained virological responses (SVRs); the other primary outcomes were safety and tolerability. RESULTS Thirty-three patients were enrolled in the study. The median HCV RNA viral load at baseline was 6.8 log10 IU/mL. Twenty-four patients were infected with HCV genotype 2a, seven patients with 1b, and two patients with 2a+1b. All patients achieved a SVR at 12 weeks after the end of treatment. The treatment was well tolerated, and there were no drug-related serious adverse events. CONCLUSION A half dose of sofosbuvir (200 mg once daily) plus a full dose of daclatasvir (60 mg once daily) were suitable for the treatment of acute HCV-infected patients who were undergoing end-stage renal disease and were on haemodialysis.

Generic daclatasvir plus sofosbuvir, with or without ribavirin, in treatment of chronic hepatitis C: real-world results from 18 378 patients in Egypt. Aliment Pharmacol Ther 2018; 47:421-431. [PMID: 29193226 DOI: 10.1111/apt.14428] [Citation(s) in RCA: 68] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Revised: 08/22/2017] [Accepted: 10/30/2017] [Indexed: 12/19/2022]
Abstract
BACKGROUND Treatment of chronic hepatitis C using combination of sofosbuvir (SOF) and daclatasvir (DCV) was used in several clinical trials and multicentre studies, which were somewhat limited to genotypes 1-3. The national program in Egypt is using SOF-DCV combination for large scale treatment. AIM To assess the efficacy and safety of combined SOF-DCV in treating patients with HCV-G4 in a real-world setting. METHODS Data and outcome of chronic HCV patients who were treated for 12 weeks with generic medications: DCV 60 mg plus SOF 400 mg ± ribavirin (RBV) within the national hepatitis C treatment program in Egypt are presented. Treatment-naïve patients without cirrhosis were treated without RBV, and those who had cirrhosis or were treatment-experienced (interferon experienced or SOF experienced) received RBV. Efficacy and safety were assessed, and baseline factors associated with sustained virological response at post-treatment week 12 (SVR12) were explored. RESULTS During the first 2 months of the programme, 18 378 patients with HCV-G4 started treatment with SOF-DCV with or without RBV. Overall, 95.1% achieved SVR12 (95.4% among patients treated without RBV and 94.7% for patients treated with RBV, P = .32). Treatment was prematurely discontinued in only 1.5% of patients. The most common events leading to discontinuation were patient withdrawal (n = 76) and pregnancy (n = 5). Five deaths occurred within this group. CONCLUSIONS Real-world experience of generic SOF-DCV in patients with chronic HCV-G4 proved to be safe and associated with a high SVR12 rate, in patients with different stages of fibrosis.
