Effectiveness of elbasvir/grazoprevir plus ribavirin for hepatitis C virus genotype 1a infection and baseline NS5A resistance. Ann Hepatol 2023; 28:100899. [PMID: 36632975 DOI: 10.1016/j.aohep.2023.100899] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 11/02/2022] [Accepted: 11/04/2022] [Indexed: 01/13/2023]
Abstract
INTRODUCTION AND OBJECTIVES In clinical trials, patients with hepatitis C virus (HCV) genotype (GT)1a infection and baseline resistance-associated substitutions (RASs) at amino acid positions 28, 30, 31, or 93 receiving elbasvir/grazoprevir for 12 weeks achieved lower rates of sustained virologic response (SVR) than those without baseline RASs. SVR rates in patients with RASs were improved when elbasvir/grazoprevir treatment duration was extended from 12 to 16 weeks and administered concomitantly with ribavirin. MATERIALS AND METHODS This was a retrospective, observational analysis using electronic health record abstraction. Patients with HCV GT1a infection and RASs at positions 28, 30, 31, or 93 who were prescribed 16 weeks of elbasvir/grazoprevir and ≥ 1 prescription for ribavirin were included. SVR was defined as HCV RNA below the lower limit of quantification ≥ 70 days after end of treatment. RESULTS The primary analysis included patients with baseline RASs at positions 30, 31, or 93 (n = 76); a secondary analysis included patients with RASs at positions 28, 30, 31, or 93 (n = 93). SVR was achieved by 77.6% (59/76) of patients in the primary analysis and 80.6% (75/93) of those in the secondary analysis. Of the 18 (19.4%) patients in the secondary cohort who failed to achieve SVR, 8 relapsed (4 with treatment-emergent NS5A substitutions) and 10 did not have viral sequencing to distinguish relapse from reinfection. CONCLUSIONS This analysis highlights the opportunities in leveraging real-world data to further understand treatment outcomes in smaller, discrete subgroups of patients with HCV infection who cannot be thoroughly evaluated in clinical trials.

A New Artificial Intelligence Approach Using Extreme Learning Machine as the Potentially Effective Model to Predict and Analyze the Diagnosis of Anemia. Healthcare (Basel) 2023; 11:healthcare11050697. [PMID: 36900702 PMCID: PMC10000789 DOI: 10.3390/healthcare11050697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 02/09/2023] [Accepted: 02/16/2023] [Indexed: 03/02/2023] Open
Abstract
The procedure to diagnose anemia is time-consuming and resource-intensive due to the existence of a multitude of symptoms that can be felt physically or seen visually. Anemia also has several forms, which can be distinguished based on several characteristics. It is possible to diagnose anemia through a quick, affordable, and easily accessible laboratory test known as the complete blood count (CBC), but the method cannot directly identify different kinds of anemia. Therefore, further tests are required to establish a gold standard for the type of anemia in a patient. These tests are uncommon in settings that offer healthcare on a smaller scale because they require expensive equipment. Moreover, it is also difficult to discern between beta thalassemia trait (BTT), iron deficiency anemia (IDA), hemoglobin E (HbE), and combination anemias despite the presence of multiple red blood cell (RBC) formulas and indices with differing optimal cutoff values. This is due to the existence of several varieties of anemia in individuals, making it difficult to distinguish between BTT, IDA, HbE, and combinations. Therefore, a more precise and automated prediction model is proposed to distinguish these four types to accelerate the identification process for doctors. Historical data were retrieved from the Laboratory of the Department of Clinical Pathology and Laboratory Medicine, Faculty of Medicine, Public Health, and Nursing, Universitas Gadjah Mada, Yogyakarta, Indonesia for this purpose. Furthermore, the model was developed using the algorithm for the extreme learning machine (ELM). This was followed by the measurement of the performance using the confusion matrix and 190 data representing the four classes, and the results showed 99.21% accuracy, 98.44% sensitivity, 99.30% precision, and an F1 score of 98.84%.

Abstract
Haemophilia is a rare, hereditary bleeding disorder. Clotting factor concentrates were a revolutionary treatment which changed the life of people with haemophilia. However, early generation of clotting factor concentrates, without viral inactivation procedures in the manufacturing process, led to an increased risk of transmission of blood-borne viral infections, mainly due to hepatitis C virus and human immunodeficiency virus. As only 20% of HCV-infected patients clear the infection naturally, chronic HCV infection constitutes a serious health problem and a major cause of chronic liver disease in this group of patients. Fortunately, the use of viral inactivation procedures in the plasma-derived factor concentrates manufacturing process and the availability of alternative treatment options, led to a significant reduction of transfusion-associated viral infections. The advent of multiple, orally administrated, highly effective direct-acting antivirals (DAAs) is changing the natural history of HCV infection in patients with haemophilia as these drugs have an excellent safety profile and achieve very high sustained virological response rates, similar to the general population. Eradication of HCV-infection in patients with haemophilia is feasible via micro-elimination projects.

Abstract
BACKGROUND In people with chronic hepatitis C virus (HCV) infection, viral eradication is associated with improved health-related quality of life (HRQOL). OBJECTIVE To assess changes in HRQOL among participants receiving opioid agonist therapy undergoing treatment for HCV infection. METHODS COSTAR (NCT02251990) was a randomized, double-blind, placebo-controlled study. Adults with HCV infection on opioid agonist therapy received elbasvir (50 mg)/grazoprevir (100 mg) or placebo for 12 weeks. HRQOL was evaluated using the Medical Outcomes Study 36-Item Short Form Health Survey version 2 (SF-36v2) Acute Form. Participants remained blinded until 4 weeks after end of treatment. RESULTS Overall, 201 participants received elbasvir/grazoprevir and 100 participants received placebo. Treatment difference mean change from baseline scores (elbasvir/grazoprevir minus placebo) indicated an improvement in HRQOL at 4 weeks after end of treatment in participants receiving elbasvir/grazoprevir versus those receiving placebo, driven by declining HRQOL in those receiving placebo and improved HRQOL in certain domains among participants receiving elbasvir/grazoprevir. Notable differences in SF-36v2 scores were evident in the general health (mean treatment difference [MTD], 6.00; 95% CI, 1.37-10.63), vitality (MTD, 6.81; 95% CI, 1.88-11.75), and mental health (MTD, 5.17; 95% CI, 0.52-9.82) domains and in the mental component summary score (mean, 2.83; 95% CI, 0.29-5.37). No notable between-treatment differences were evident at treatment weeks 4 or 12. CONCLUSION HRQOL in patients receiving medication for opioid dependence was improved following treatment for HCV infection with elbasvir/grazoprevir, suggesting that eradication of HCV infection with direct-acting antivirals is associated with improved HRQOL. TRIAL REGISTRATION NUMBER ClinicalTrials.gov, NCT02251990.

Abstract
Background: Hepatitis C virus (HCV) infections in the United States have increased in recent years, with the most rapid rise among people who inject drugs (PWIDs). Historically, there have been concerns regarding treatment adherence among PWIDs with HCV infection, leading to undertreatment of this population and increased HCV transmission. Elbasvir (EBR)/grazoprevir (GZR) has demonstrated high rates of virologic cure (sustained virologic response [SVR]) in clinical trials enrolling PWIDs with HCV infection. Objective: To evaluate the real-world effectiveness of EBR/GZR in HCV genotype (GT) 1-infected patients with a diagnosis of opioid use disorder. Methods: A retrospective analysis of electronic medical records from the US Department of Veterans Affairs Corporate Data Warehouse. Adults with chronic HCV GT1 infection, ≥1 prescription for EBR/GZR, and ≥1 clinic visit were included. All patients had ≥1 ICD-9/10 code of opioid use disorder. SVR was the primary outcome. Results: 419 patients were included; 97.1% had a history of any illicit drug use and 40.8% were receiving medication for opioid use disorder (MOUD). SVR was achieved by 96.9% (406/419) of all patients, 97.0% (350/361) of those receiving EBR/GZR for 12 weeks, and 95.3% (163/171) of those receiving MOUD. SVR in patients receiving psychiatric medications ranged from 96.1% (221/230) in those taking antidepressant medications to 98.5% (128/130) in those taking mood stabilizers. Conclusion: In this real-world setting, high rates of virologic cure were achieved in patients with HCV GT1 infection on MOUD receiving EBR/GZR for 12 weeks, including patients with multiple comorbidities and high rate of psychiatric medication use.

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
BACKGROUND Chronic hepatitis C virus (HCV) infection represents a crucial health problem in children that greatly influences their quality of life. Many efforts have been directed toward investing in effective drugs with a high safety profile and oral administration for better compliance. OBJECTIVES This study aims to assess the safety of a fixed-dose combination of ledipasvir/sofosbuvir plus drug efficacy and sustained virologic response (SVR) at 12 weeks after treatment discontinuation. METHOD One tablet (90 mg ledipasvir, 400 mg sofosbuvir) was administered to treatment-naïve children aged 12-18 years weighing at least 35 kg with chronic HCV infection for 6 months, genotype 4. Patients were divided into 2 groups, (1) without comorbidities (24 patients) and (2) with comorbidities (26 patients). RESULTS At the end of the therapy, all patients (100%) had SVR and a significant reduction of liver enzymes with mild tolerable side effects. CONCLUSION Ledipasvir/sofosbuvir fixed-dose combination is a safe and highly effective therapeutic option in Egyptian children aged ≥ 12 years, with chronic HCV infection, genotype 4, either without or with comorbidities.

Abstract
BACKGROUND Patients with inherited blood disorders (IBLD) have a high risk of hepatitis C virus (HCV) infection. The aim of this work was to assess the efficacy and safety of HCV direct-acting antiviral (DAA)-based treatment in patients with IBLD and chronic HCV infection. METHODS Twenty-seven patients (25 with sickle cell disease, 1 with β-thalassemia and 1 with hemoglobin D-Punjab), including 3 with compensated cirrhosis, were included. They were treated with sofosbuvir in combination with ribavirin, daclatasvir, ledipasvir, or velpatasvir or with grazoprevir/elbasvir for 8 or 12 weeks. In the case of treatment failure, in-vitro assessment of resistance-associated substitutions (RASs) and full-length genome sequence analysis by means of deep sequencing were performed. RESULTS Treatment was safe and well-tolerated and there were no drug discontinuations due to DAA-related adverse events. Twenty-five out of the 27 patients (93%) achieved sustained virological response 12 weeks post-treatment. One patient discontinued after 18 days due to adverse events unrelated to the antiviral treatment. One patient infected with 'unusual' genotype 2 subtype 2m relapsed. Subtype 2m naturally carries the NS5A L31M RAS. In a genotype 2a subgenomic replicon model, L31M increased daclatasvir effective concentration 50% (EC50) by 97-fold, but velpatasvir EC50 by only 3-fold, without altering the replication capacity. This patient was successfully retreated with sofosbuvir/velpatasvir for 12 weeks. CONCLUSION DAA-based regimens are well tolerated and highly efficacious in patients with chronic hepatitis C and IBLD in the real-world setting. Thus, DAA-based antiviral treatment should be prioritized in this thus far neglected population of HCV-infected patients.

Abstract
Abstract
Background
Patients with chronic hemolytic anemias (CHA) are at a high risk for transfusion-transmitted infections. Various studies in Egypt have shown a prevalence of hepatitis C virus (HCV) infection in 24–37% of those patients. Elimination of hepatitis C virus (HCV) in patients with CHA would prevent early progression of liver disease. In this study, we aimed to assess the efficacy, safety, and tolerability of sofosbuvir (SOF) and daclatasvir (DAC) in the special population of HCV-infected patients with CHA. In this prospective study, 21 consenting hepatitis C patients were recruited and treated using ribavirin-free SOF/DAC regimen for either 12 or 24 weeks according to categorization of patients into easy or hard-to-treat in accordance with the national protocols. Sustained virological response was assessed by RT-PCR for HCV-RNA at 12 weeks post-treatment (SVR12). Any treatment-related adverse events were noted.
Results
All patients were adherent to treatment with no discontinuation of therapy. SVR12 was achieved in 19 out of 21 patients (90.5%). There was a significant improvement in levels of ALT (p<0.009) after completion of therapy. On the other hand, the hemoglobin, total bilirubin, and ferritin levels showed a non-significant difference (p<0.501, p<0.542, and p<0.339, respectively). Moderate adverse events were observed in 2 out of 21 patients (9.5%), including sickling crisis and hepatic decompensation.
Conclusion
The results of this study substantiate the favorable efficacy, safety, and tolerability of ribavirin-free direct-acting antivirals (DAAs) in the special population of HCV-infected patients with CHA. Micro-elimination of HCV in special patient populations allows for pragmatic delivery of care to patients with co-morbid conditions who are in most need for treatment and allows for achievement of global elimination of HCV worldwide.

Abstract
Abstract
Background
Hepatitis C virus (HCV) infection is a major cause of liver-related morbidity and mortality among thalassemic patients. Direct-acting antiviral agents (DAAs) are highly effective and well-tolerated by chronic HCV patients.
Results
The mean age of our patients was 29 years. Sustained virologic response (SVR) at 12 and 24 weeks was achieved in all patients (100%). The most common side effects were fatigue (18%), anemia (13.63%), and headache (4.5%). There was no statistically significant difference in the hemoglobin level before and after treatment (p = 0.48). There was a significant improvement in serum bilirubin and mean ALT levels after treatment compared to baseline data (p < 0.0005 each).
Conclusions
DAAs, namely, sofosbuvir plus daclatasvir or sofosbuvir plus ledipasvir, are effective and well-tolerated regimens in thalassemic patients with chronic HCV.

Abstract
The introduction of clotting factor concentrates has substantially improved the lives of people with clotting factor deficiencies. Unfortunately, the transmission of blood-borne viral infections through these plasma-derived products led to a huge epidemic of human immunodeficiency virus and viral hepatitis in people with haemophilia (PWH). In a significant proportion of PWH exposed to these viruses, the ensuing decades-long chronic infection resulted in excess morbidity and mortality. Fortunately, developments in the safety of blood products, as well as vaccination and highly effective antiviral treatments have improved the prospects of PWH. The present article reviews the background of the viral hepatitis epidemic in PWH, the natural history of hepatitis B and C infections and their long-term management.

Utilization and effectiveness of elbasvir/grazoprevir and adoption of resistance-associated substitutions testing in real-world treatment of hepatitis C virus genotype 1A infection: results from the German Hepatitis C-Registry. Eur J Gastroenterol Hepatol 2021; 33:415-423.

Abstract
BACKGROUND For treatment of genotype 1a (GT1a) infection with elbasvir/grazoprevir, the German guidelines recommend a differentiated approach depending on baseline viral load (BVL). For low BVL ≤800 000 IU/mL, treatment with 12 weeks elbasvir/grazoprevir should be considered, whereas for high BVL >800 000 IU/mL, this regimen is only recommended in nonstructural protein 5A (NS5A) resistance-associated substitutions (RAS) absence. With present NS5A RAS or when RAS-testing is not available, 16 weeks elbasvir/grazoprevir + ribavirin is preferred. Here, we investigated the adherence to these recommendations and the effectiveness of elbasvir/grazoprevir in a large German Hepatitis C-Registry GT1a cohort. METHODS From September 2016 until July 2018, 195 GT1a-infected patients were treated with elbasvir/grazoprevir ± ribavirin for 12-16 weeks. The primary outcome was per protocol SVR12 or SVR24. RESULTS Mean age was 50 years, 89% were male, 19% had cirrhosis, 72% were treatment-naïve. Forty-five percent had low BVL ≤800 000 IU/mL, 55% high BVL >800 000 IU/mL, of whom 49 vs. 42% were baseline RAS-tested. Four patients with high (7.7%) and two with low BVL (5%) had NS5A RAS of whom 50% received elbasvir/grazoprevir+ribavirin, respectively. Ninety-four percent of patients with low and 65% with high BVL received elbasvir/grazoprevir without ribavirin. Thirty-five percent of patients with high BVL received ribavirin, mostly without prior RAS-testing. Per protocol sustained virologic response (SVR) by low vs. high BVL was 98.8 and 95.1%. All patients with NS5A RAS achieved SVR. CONCLUSIONS In German, real-world most patients received elbasvir/grazoprevir without ribavirin. Ribavirin was mainly added in GT1a patients >800 000 IU/mL, who were not NS5A RAS tested. SVR rates were consistently high and comparable to clinical trial results.

Abstract
Background&Aims:Patients with thalassemia have lifelong need for blood transfusion, makes them more risky to hepatitis C virus (HCV). Iron overload and chronic HCV are considered risk factors for patients with thalassemia to develop liver insults. The aim of the present study is to investigate the safety and efficacy of sofosbuvir/ledipasvir in treatment of chronic HCV infection in Egyptian adult patients with β- thalassemia major. METHODS Aretrospective study included 53 patients with β-thalassemia major with chronic HCV treated with sofosbuvir (400 mg) and ledipasvir (90 mg) as a single pill fixed dose combination once daily for 12 weeks. The effectiveness of treatment was assessed by sustained virologic response (SVR) at 12 weeks after the end of treatment. RESULTS SVR was achieved in 96.23% of patients. 47.17% of patients had minor side effects. There was a significant reduction in ALT, AST, and serum ferritin 12 weeks post-therapy. There was insignificant change in hemoglobin level, or blood transfusion requirement 12 weeks post-therapy. There was no change in iron chelators doses throughout the study period. CONCLUSION Sofosbuvir/ledipasvir regimen seems to be safe and highly effective in treatment of chronic HCV in patients with β-thalassemia major.

Abstract
Direct-acting antiviral treatments for chronic hepatitis C virus (HCV) infection are generally safe; however, understanding the safety profile of each regimen is essential for their continued use. Safety data were pooled from 12 clinical trials of elbasvir/grazoprevir (EBR/GZR) that enrolled adult participants with HCV infection. Pooled analyses are presented for participants receiving EBR/GZR for 12 weeks and those receiving EBR/GZR plus ribavirin (RBV) for 16-18 weeks. Safety data are also presented for participants with comorbidities receiving EBR/GZR for 12 weeks in individual clinical trials (chronic kidney disease [CKD] stage 4/5, inherited blood disorders [IBLD] or receiving opioid agonist therapy [OAT]). Among 1743 participants receiving EBR/GZR for 12 weeks, 1068 (61.3%) reported ≥1 adverse event (AE) and 491 had AEs (28.2%) considered drug-related. The most frequent AEs were headache (10.6%), fatigue (8.7%), nasopharyngitis (5.8%), nausea (5.1%) and diarrhoea (5.0%). Serious AEs were reported by 37 participants (2.1%), and 12 (0.7%) discontinued treatment due to an AE. In populations with CKD 4/5 or IBLD or receiving OAT, safety was similar in participants receiving EBR/GZR for 12 weeks and those receiving placebo. Some AEs occurred at higher frequencies in participants receiving RBV compared with those receiving EBR/GZR alone: fatigue (32.7% vs 8.7%); headache (21.6% vs 10.6%); and nausea (15.8% vs 5.1%). Safety was similar in participants with and those without cirrhosis. Grade 3/4 alanine aminotransferase elevations were reported in 0.7% participants. EBR/GZR is a safe treatment option for individuals with HCV genotype (GT) 1 or GT4 infections, even those with challenging comorbidities such as CKD or IBLD and those receiving OAT.

Abstract
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease, with approximately 71 million chronically infected individuals worldwide. Clinical care for patients with HCV-related liver disease has advanced considerably thanks to an enhanced understanding of the pathophysiology of the disease, as well as developments in diagnostic procedures and improvements in therapy and prevention. These therapies make it possible to eliminate hepatitis C as a major public health threat, as per the World Health Organization target, although the timeline and feasibility vary from region to region. These European Association for the Study of the Liver recommendations on treatment of hepatitis C describe the optimal management of patients with recently acquired and chronic HCV infections in 2020 and onwards.

Abstract
Although persons with nonsevere hemophilia A (NSHA) account for about one-half of the hemophilia A population, epidemiological data in this subset of individuals are scarce. We set out to describe the clinical characteristics of persons with NSHA with inhibitors, and to determine mortality rates, predictors of mortality, and primary causes of death in persons with NSHA in the United States over a 9-year period (2010-2018). We queried the American Thrombosis and Hemostasis Network dataset (ATHNdataset) for information on demographics, inhibitor status, and date and cause of death. A total of 6624 persons with NSHA (86.0% men; 14.0% women) were observed for an average of 8.5 years; total 56 119 person-years . The prevalence of inhibitors was 2.6% (n = 171), occurring at a median age of 13 years. At the end of follow-up, 136 persons died at a median age of 63 years; an age-adjusted mortality rate of 3.3 deaths per 1000 person-years. Three deaths occurred in inhibitor participants. Presence of inhibitors was not associated with increased mortality risk (hazard ratio [HR], 0.7, 95% confidence interval [CI], 0.2-2.3). Factors independently associated with increased risk of death (HR, 95% CI) were the following: age (10-year increase) (2.1, 2.0-2.4); male (2.6, 1.0-6.4); hepatitis C (2.2, 1.5-3.1); and HIV (3.6, 2.2-6.0). The most common primary cause of death was malignancy (n = 27, 20.0%). In persons with NSHA, the development of inhibitors occurred at an early age and was not associated with increased mortality.

Abstract
BACKGROUND The combination of elbasvir and grazoprevir (EBR/GZR) has been approved for treating HCV infection. This study aimed to evaluate the efficacy of EBR/GZR in terms of sustained virological response (SVR) and improvement of liver fibrosis in Thai patients with HCV genotype-1 (GT1). The utility of serum HCV core antigen (HCVcAg) as an alternative to HCV RNA in assessing SVR was also investigated. METHODS A total of 101 HCV GT1-infected patients (65 monoinfection and 36 HIV coinfection) who received EBR/GZR for 12-16 weeks were included. Liver stiffness (LS) and controlled attenuation parameter (CAP) were measured by transient elastography. Serum HCVcAg was measured in parallel with HCV RNA. RESULTS The overall SVR12 and SVR24 rates in the cohort were 98.0% and 95.0%, respectively. SVR24 rates were consistently high (90.0% to 100%) across all subgroups of patients. A significant LS decline ³30% was observed more frequently in cirrhotic than non-cirrhotic individuals who achieved SVR (63.3% versus 30.3%; P=0.003). The magnitude of LS decline following HCV eradication was comparable between HCV monoinfection and HCV-HIV coinfection. The reduction of CAP was also observed in responders who had significant steatosis at baseline. Compared with HCV RNA, HCVcAg testing displayed high sensitivity (100%) and specificity (99.0-100%) in determining SVR12 and SVR24. CONCLUSIONS This study confirms that EBR/GZR is effective for HCV GT1-infected Thai patients with or without HIV infection. HCV eradication is associated with LS and CAP improvement regardless of HIV status. HCVcAg testing could be a potential replacement for HCV RNA for assessing SVR in resource-limited settings.

Abstract
Background: In the United States, the number of new cases of hepatitis C virus infection has risen in recent years, driven largely by transmission among young white adults in their 20s and 30s. Herein, we report an integrated analysis of participants with hepatitis C virus infection aged ≤35 years from 12 phase II/III clinical trials of elbasvir/grazoprevir.Methods: Treatment-naive and -experienced adults with hepatitis C virus genotype 1 or 4 infection received elbasvir (50 mg/day)/grazoprevir (100 mg/day) for 12 weeks without ribavirin. Analyses were stratified according to participant age (≤35 years vs >35 years). The primary endpoint was sustained virologic response (hepatitis C virus RNA < lower limit of quantitation at 12 weeks after completion of therapy).Results: Sustained virologic response was achieved by 98.9% (271/274) of participants aged ≤35 years and by 96.9% (2093/2160) aged >35 years. Three participants aged ≤35 years with genotype 1b infection relapsed. Eight participants with genotype 1a infection and baseline non-structural protein 5 A resistance-associated substitutions achieved sustained virologic response. Similarly, all 85 participants aged ≤35 years with genotype 1a infection and no baseline non-structural protein 5 A resistance-associated substitutions achieved sustained virologic response. Safety was favorable, with the incidence of drug-related adverse events similar in younger and older participants (30.1% vs 30.6%). One participant (0.4%) aged ≤35 years and 15 participants (0.7%) aged >35 years discontinued treatment owing to adverse events.Conclusions: Elbasvir/grazoprevir for 12 weeks was safe and highly effective in participants aged ≤35 years with hepatitis C virus genotype 1 or 4 infection.

Abstract
Hepatitis C is a global public health threat. The introduction of direct-acting antivirals (DAAs) brings the prospect of curing the 71 million people living with the disease, dramatically changing the landscape of hepatitis C. The World Health Organization developed a roadmap for the elimination and cure of hepatitis C by 2030 with a clear goal with measurable targets. However, there is a lack of a well-defined strategy to tackle the hepatitis C virus (HCV) problem in children and adolescents vis-à-vis the adult population. Hepatitis C in children and adolescents can be addressed as part of a national policy for elimination in the whole population, namely macroelimination, or could be fragmented into a microelimination approach targeting the high-risk population groups. Children born to HCV-infected mothers, adolescents who are injecting drugs, migrants, and those suffering from inherited blood diseases are important target populations. After the U.S. Food and Drug Administration approval for the use of DAAs in children aged 3 years and above, evidence from clinical trials and real-world experience was accumulated using brand and generic medicines, with sustained virological response rates exceeding 95%. The evidence created should guide policies on the management of hepatitis C in children and adolescents. There are many challenges in managing HCV in this left-behind marginalized population. The lack of awareness and epidemiological data, consent age, prohibitive prices of medicines, and absence of policies on access to diagnostics, treatment, and linkage to care are among the many barriers to service delivery that should be addressed to achieve the elimination goal by 2030.

Abstract
Background and Aim In China, clinical experience with direct‐acting antiviral treatments for hepatitis C virus (HCV) infection is still emerging. C‐CORAL is a phase 3, multinational, placebo‐controlled, double‐blind trial of elbasvir/grazoprevir (EBR/GZR) in participants with HCV infection from the Asia‐Pacific region and Russia. Here, we report the data from participants enrolled in China. Methods Treatment‐naive participants with chronic HCV genotype (GT) 1, GT4, or GT6 infection were randomly assigned to receive 50 mg EBR/100 mg GZR for 12 weeks (immediate‐treatment group, ITG) or placebo followed by deferred treatment with EBR/GZR (deferred‐treatment group, DTG). The primary efficacy end‐point was sustained virologic response at 12 weeks after completing treatment (SVR12), and the primary safety end‐point was a comparison of safety between participants receiving EBR/GZR and placebo (NCT02251990; Protocol PN‐5172‐067). Results A total of 152 participants in China were randomly assigned (ITG, n = 115; DTG, n = 37). SVR12 was achieved in 96.7% (146/151) participants overall and in 97.3% (142/146) of those with GT1b infection. Four participants relapsed (GT1b, n = 3; GT6a, n = 1). Drug‐related AEs were reported in 25 (21.7%) and 9 (24.3%) participants receiving EBR/GZR and placebo, respectively; no drug‐related serious adverse events (AEs) occurred. Two (1.7%) participants receiving EBR/GZR had late hepatic transaminase elevations. Patient‐reported outcomes indicate improved quality of life at follow‐up week 4 in participants receiving EBR/GZR compared to placebo. Conclusion EBR/GZR administered for 12 weeks represents a highly effective and safe treatment option for Chinese individuals with HCV GT1 infection.

Abstract
Hepatitis C virus (HCV) infection is a silent killer that leads to rapid progression of liver cirrhosis and hepatocellular carcinoma (HCC). High prevalence of HCV infection has been reported in Taiwan, especially in high-risk populations including people who inject drugs (PWID) and patients requiring dialysis. Besides, certain populations merit special considerations due to suboptimal outcome, potential drug-drug interaction, or possible side effect. Therefore, in the second part of this 2-part consensus, the Taiwan Association for the Study of the Liver (TASL) proposes the treatment recommendations for the special population in order to serve as guidance to optimizing the outcome in the direct-acting antiviral (DAA) era. Special populations include patients with acute or recent HCV infection, previous DAA failure, chronic kidney disease, decompensated cirrhosis, HCC, liver and other solid organ transplantations, receiving an HCV viremic organ, hepatitis B virus (HBV) and HCV dual infection, HCV and human immunodeficiency virus (HIV) coinfection, active tuberculosis infection, PWID, bleeding disorders and hemoglobinopathies, children and adolescents, and pregnancy. Moreover, future perspectives regarding the management of hepatitis C are also discussed and summarized in this consensus statement.

Abstract
AUTHOR CONTRIBUTION FN performed the literature review and wrote the manuscript; STZ coauthored, edited, and reviewed the manuscript. ABSTRACT Treatment response in Hepatitis C virus (HCV) has generated varied effects in patients. Recently, nonresponsive and relapse patients related to host and genotype variabilities have been reported in clinical trials. However, these trials included minimal sample sizes of patients with genotype 4, the most prevalent genotype in Egypt and the Middle East, compared with genotypes 1 and 2. The genetic variabilities that have been detected within the HCV genes, especially the ones associated with genotype 4, and are linked to treatment response, will be the focus of this review with emphasis on direct acting antiviral agents. In addition, the major studies and clinical trials performed globally and their inclusivity of genotype 4 are reported. This review also delineates future study areas and missing data that need further investigation when it comes to genotype 4.

Abstract
INTRODUCTION Real-world treatment of hepatitis C virus (HCV) infection is complicated by many factors that are controlled for in the rigorous clinical trial setting. The aim of the present study was to assess the efficacy of elbasvir/grazoprevir in a Veterans Affairs population with chronic HCV genotype 1b infection. METHODS This was a retrospective analysis of a cohort of patients aged ≥ 18 years with chronic HCV genotype 1b infection and ≥ 1 prescription of elbasvir/grazoprevir between February 1, 2016, and August 31, 2017. The primary analysis was conducted in the per-protocol population, which included all patients who had at least 11 weeks of treatment and had an available assessment for sustained virologic response (SVR) based on virologic data post-follow-up week 4. RESULTS The per-protocol population included 3371 patients. Overall, 97.3% of patients were male, 60.3% were black, and 85.5% were HCV treatment-experienced. Comorbidities in this population included hypertension (74.4%), history of alcohol use (55.7%), and depression (54.8%). In total, 97.5% of patients (3288/3371) achieved SVR. Among patient sub-groups, SVR was achieved by 96.0% (290/302) of those with chronic kidney disease stage 4/5, 97.8% (1527/1561) of those with a history of drug use, and 96.6% (831/860) of those with cirrhosis. No statistically significant differences were observed in the proportions of patients achieving SVR, regardless of age, race, HCV treatment history, viral load level, treatment regimen/duration, history of drug or alcohol use, HIV co-infection, or chronic kidney disease. CONCLUSION Elbasvir/grazoprevir was highly effective in individuals with HCV genotype 1b infection in a large national Veterans Affairs clinical setting.

Abstract
Elbasvir/grazoprevir with or without ribavirin has excellent efficacy and safety for the treatment of hepatitis C virus (HCV) genotype 1 and 4 patients. The real-world experience has been reported but the detailed analysis of liver and renal adverse effects is lacking. This study evaluated the real-world experience relating to the effectiveness and liver/renal safety of elbasvir/grazoprevir in HCV genotype 1 patients with compensated liver disease. In the four medical centres of Chang Gung Medical System, 350 HCV genotype 1 patients with compensated liver disease who were treated with elbasvir/grazoprevir were enrolled. Clinical characteristics and laboratory data were collected. The effectiveness (sustained virologic response 12 weeks after end of treatment, SVR12) and safety were assessed. A consecutive series of 350 patients with a mean age of 68.8 ± 10.0 years old were enrolled. The majority were treatment-naïve (72.3%), genotype 1b (97.7%) and advanced fibrosis/cirrhosis (94.3%). Seventy-nine (22.6%) had hepatocellular carcinoma and 23 (6.6%) had coinfection with hepatitis B. The effectiveness of SVR12 was 94.6% (95% CI: 92.2%-97.0%) in the full analysis set and 99.1% (95% CI: 98.1%-100.1%) in the per-protocol set. There were two relapses and one nonresponder. Seven (2.0%) patients had adverse events resulting in premature discontinuation of treatment. Five of them were considered drug-related. One was due to autoimmune hepatitis. Contrary to previous reports, around 49% of ALT elevation was observed after 8 weeks, and in two patients was due to hepatitis B flares. As to the renal function during the course of therapy, a minor deterioration of eGFR was observed in patients with baseline eGFR ≥60 mL/min/1.73 m2 , but not in those with baseline eGFR <60, <60-30 or <30 mL/min/1.73 m2 . In this real-world data, elbasvir/grazoprevir was effective with few liver/renal adverse effects. One patient developed autoimmune hepatitis.

Abstract
BACKGROUND AND AIMS Chronic hepatitis C is the main co-morbidity in adult patients with haemophilia (PwH). It causes progressive liver damage leading to end-stage liver disease and/or hepatocellular carcinoma. Eradication of HCV was possible with interferon (IFN)-based regimens in the past and direct-acting antivirals (DAAs) more recently. PwH have been considered "difficult-to-treat" because of several bad predictors of response. The advent of DAAs has provided high rates of sustained virological response (SVR) despite bad prognostic factors. Here, we present the results of antiviral treatment with DAAs in PwH treated in 2 large Italian Hemophilia Treatment Centers. METHODS PwH and chronic hepatitis C sustained by any HCV genotype were eligible for therapy with DAAs, including those with compensated cirrhosis, HIV infection and/or previous failure to IFN-based antiviral therapy. Patients received DAAs for 8-24 weeks according to existing guidelines. SVR was defined as persistent negative serum HCV-RNA at 12 weeks after treatment completion (SVR12). RESULTS Between January 2015 and November 2018, 200 patients aged 21-84 years (median: 50.5) received DAAs. HCV genotype 1 was the most prevalent (158, 79%). Forty patients (20%) were HIV positive, 56 (28%) had cirrhosis and 91 (46%) previously failed interferon-based treatment. Ribavirin was used in 70 (35%). HCV-RNA was undetectable at week 4 in 124/192 (65%) and SVR12 was achieved in 193/195 (99%). No patient had serious side effects related to DAAs. CONCLUSIONS DAAs were safe and highly effective in PwH irrespective of HIV status, stage of liver disease severity and/or previous failure to IFN-based therapy.

Abstract
BACKGROUND & AIMS Hepatitis C virus (HCV) genotype (GT) 4 infection is prevalent in sub-Saharan Africa and the Middle East, particularly in Egypt. This study evaluated the safety and efficacy of elbasvir/grazoprevir administered for 8 and 12 weeks in participants with HCV GT4 infection. METHODS In this partially randomized, open-label multicentre study conducted in France (NCT03111108; Protocol MK5172-096), treatment-naive participants with GT4 infection and F0-F2 fibrosis were randomized 2:1 to elbasvir (50 mg)/grazoprevir (100 mg) for 8 or 12 weeks. Treatment-naive participants with F3-F4 fibrosis and all treatment-experienced participants (F0-F4) were assigned to elbasvir/grazoprevir for 12 weeks. The primary endpoint was sustained virologic response (SVR) 12 weeks after the end of therapy. RESULTS One hundred and seventeen participants were enrolled. Among treatment-naive participants with F0-F2 fibrosis, SVR was achieved by 94% (50/53) and 96% (26/27) of those receiving elbasvir/grazoprevir for 8 or 12 weeks, respectively, and four participants relapsed. In the 12-week arm, 95% (35/37) achieved SVR and two participants relapsed. NS5A resistance-associated substitutions were present at baseline and virologic failure in five of the participants with relapse. Drug-related adverse events occurred in 42% (n = 22) and 50% (n = 32) of participants receiving 8 and 12 weeks of treatment, respectively. No participant discontinued treatment owing to an adverse event. CONCLUSION These data confirm the efficacy of elbasvir/grazoprevir administered for 12 weeks in treatment-experienced individuals with HCV GT4 infection and those with advanced fibrosis. Treatment-naive individuals with mild fibrosis can be treated effectively with an 8-week regimen.

Abstract
BACKGROUND & AIMS Randomized controlled trials of EBR/GZR have reported high treatment efficacy, safety and tolerability in patients undergoing dialysis. However, real world effectiveness data for EBR/GZR in this population is lacking. We evaluated the effectiveness of EBR/GZR in an HCV-infected population with all stages of CKD including dialysis compared with control patients with estimated glomerular filtration rate (eGFR) ≥60 in the US Department of Veterans Affairs (VA). METHODS We conducted a retrospective cohort study of patients with chronic HCV genotype 1 infection with EBR/GZR prescriptions dispensed during February 1, 2016-August 31, 2017 in 128 VA Medical Centers. We collected patient information regarding history of dialysis, end stage renal disease (ESRD), and/or eGFR values. We measured SVR based on undetectable HCV RNA at least 4 weeks after the completion of treatment. We examined SVR rates by CKD stage compared to control patients and within patient subgroups using logistic regression models. RESULTS We identified 5961 patients (42.5% genotype 1a, 55.0% genotype 1b) who met eligibility criteria and completed a EBR/GZR treatment course (≥11 weeks). Approximately 73.2% (n = 4361) had eGFR ≥60 who served as control patients, 14.4% (n = 860) had Stage 3 CKD, and 12.4% (n = 740) had Stage 4-5 CKD or ESRD. Of patients with Stage 4-5 CKD/ESRD, 76.1% underwent dialysis (n = 563). The overall SVR was 96.7% in all patients, 96.4% for eGFR≥60, 98.3% in Stage 3 CKD, and 96.5% in Stage 4-5 CKD/ESRD. No statistically significant differences were found in the SVR rates in patients with or without dialysis in the Stage 4-5 CKD/ESRD patients (adjusted OR 0.91; 95% CI 0.56-1.47 and OR 1.74; 95% CI 0.63-4.81) compared with those with eGFR≥60. CONCLUSION We found EBR/GZR was effective in patients with HCV GT1 infection regardless of CKD severity or receipt of dialysis in the US VA population.

Abstract
Liver disease is an important cause of morbidity and mortality in patients with sickle cell disease (SCD). Despite this, the natural history of liver disease is not well characterized and the evidence basis for specific therapeutic intervention is not robust. The spectrum of clinical liver disease encountered includes asymptomatic abnormalities of liver function; acute deteriorations in liver function, sometimes with a dramatic clinical phenotype; and decompensated chronic liver disease. In this paper, the pathophysiology and clinical presentation of patients with acute and chronic liver disease will be outlined. Advice will be given regarding initial assessment and investigation. The evidence for specific medical and surgical interventions will be reviewed, and management recommendations made for each specific clinical presentation. The potential role for liver transplantation will be considered in detail.

Abstract
Introduction Some direct-acting antiviral regimens for hepatitis C virus (HCV) infection pose safety or efficacy concerns if coadministered with drugs containing ethinyl estradiol. The present analysis was conducted to examine the impact of concomitant oral contraceptive pills (OCP) or hormone replacement therapy (HRT) during treatment with elbasvir (EBR)/grazoprevir (GZR) in women with HCV genotype (GT)1 or GT4 infection. Methods This is a post hoc, integrated retrospective analysis of female participants with HCV GT1 or GT4 infection who received EBR 50 mg/GZR 100 mg once daily for 12 weeks in phase 2/3 clinical trials. The primary end point was sustained virologic response at 12 weeks after therapy completion (SVR12). For this analysis, participants were stratified according to whether they received OCP or HRT during the original treatment study. Results A total of 1,022 women with HCV GT1 or GT4 infection were included (receiving OCP/HRT, n=81; not receiving OCP/HRT, n=941). Most participants receiving OCP/HRT were treatment-naive (79%), noncirrhotic (91.4%), and aged >35 years (71.6%). SVR12 rates were similar in women receiving OCP/HRT and those not receiving OCP/HRT (95.1% vs 96.3%). SVR12 rates remained high across all subgroups within the population receiving OCP/HRT: SVR12 rates were 94.6%, 100%, and 100% in participants with GT1a, GT1b, and GT4 infection, and all women aged 18-35 years achieved SVR (21/21). Treatment-related adverse events occurred in 40.7% (33/81) and 30.1% (283/941) of women receiving and those not receiving OCP/HRT, respectively. Conclusion The efficacy and safety of EBR/GZR administered for 12 weeks was similar in women receiving OCP/HRT and those not on OCP/HRT. These data indicate that EBR/GZR can be safely used for the treatment of HCV GT1 or GT4 infection in women receiving concomitant OCP/HRT.

Abstract
It has been estimated by the World Health Organization (WHO) that over 71 million people were infected with the hepatitis C virus (HCV) in 2015. Since then, a number of highly effective direct-acting antiviral (DAA) regimens have been licensed for the treatment of chronic HCV infection: sofosbuvir/daclatasvir, sofosbuvir/ledipasvir, elbasvir/grazoprevir, sofosbuvir/velpatasvir, glecaprevir/pibrentasvir, and sofosbuvir/velpatasvir/voxilaprevir. With these treatment regimens, almost all chronic HCV-infected patients, even including prior DAA failures, can be treated effectively and safely. It is therefore likely that further development of DAAs will be limited. In this descriptive review we provide an overview of the clinical pharmacokinetic characteristics of currently available DAAs by describing their absorption, distribution, metabolism, and excretion. Potential drug-drug interactions with the DAAs are briefly discussed. Furthermore, we summarize what is known about the pharmacodynamics of the DAAs in terms of efficacy and safety. We briefly discuss the relationship between the pharmacokinetics of the DAAs and efficacy or toxicity in special populations, such as hard to cure patients and patients with liver cirrhosis, liver transplantation, renal impairment, hepatitis B virus or HIV co-infection, bleeding disorders, and children. The aim of this overview is to educate/update prescribers and pharmacists so that they are able to safely and effectively treat HCV-infected patients even in the presence of underlying co-infections or co-morbidities.

Abstract
BACKGROUND AND AIM Estimates suggest that in Asia, more than 31 million individuals have hepatitis C virus infection. The present analysis was conducted to assess the efficacy and safety of elbasvir/grazoprevir in Asian participants enrolled in the elbasvir/grazoprevir phase 2/3 clinical trials. METHODS This is an integrated analysis of data from 12 international phase 2/3 clinical trials. Asian participants with chronic hepatitis C virus genotype 1 or 4 infection who received elbasvir 50 mg/grazoprevir 100 mg once daily for 12 weeks or elbasvir/grazoprevir plus ribavirin for 16 weeks were included in this analysis. The primary end point was sustained virologic response at 12 weeks after completion of therapy (SVR12). RESULTS Seven hundred eighty Asian participants from 15 countries were included in this analysis. SVR12 was achieved by 756/780 (96.9%) of all participants, including 748/772 (96.9%) of those who received elbasvir/grazoprevir for 12 weeks and 8/8 (100%) of those who received elbasvir/grazoprevir plus ribavirin for 16 weeks. In the genotype 1b-infected population, the SVR12 rate was 691/709 (97.5%), and there was no impact of age, high baseline viral load, or presence of cirrhosis. The most frequently reported adverse events were nasopharyngitis (8.0%), upper respiratory tract infection (5.4%), and diarrhea (5.2%). Twenty participants receiving elbasvir/grazoprevir for 12 weeks reported a total of 25 serious adverse events, and 7 (0.9%) discontinued treatment because of an adverse event. CONCLUSION Elbasvir/grazoprevir administered for 12 weeks is an effective and generally well-tolerated treatment option for Asian individuals with hepatitis C virus genotype 1b infection.

Abstract
Patients with sickle cell disease can develop liver disease as a result of intrahepatic sickling of erythrocytes, viral hepatitis and iron overload secondary to multiple blood transfusions, and gallstone disease as a result of chronic hemolysis. The spectrum of clinical liver disease is wide and often multifactorial. Some patients develop cirrhosis that may progress to end-stage liver failure. Limited evidence exists for medical treatments. Exchange blood transfusions may improve outcomes in the acute liver syndromes. Liver transplantation may be an option for chronic liver disease. The role for prophylactic cholecystectomy in preventing complications of gallstone disease is controversial.

Abstract
BACKGROUND AND AIMS Direct antiviral agents (DAAs) have revolutionised the standard of care for the treatment of hepatitis even in patients with hemoglobinopathies. The aim of this study is to show how, thanks to DAAs, HCV infection has been substantially eradicated in one of the biggest Centres for the management of Thalassemia in Europe. METHODS Thalassemia major patients regularly transfused and iron chelated in Cagliari (Italy) who were HCV-RNA positive were evaluated for the potential prescription of antiviral therapy. RESULTS A total of 99 patients, 26 of whom had been diagnosed with cirrhosis, were treated with at least one dose of DAAs, which proved to be safe and well tolerated. Two of the patients died during the treatment after becoming HCV-RNA negative while another voluntarily interrupted the therapy. The final SVR in the patients who completed the treatment was 100%, while measuring 97% (96/99) in the Intention-to-Treat analysis. After DAAs, no new cases of hepatocellular carcinoma have been reported. CONCLUSIONS The use of DAAs in patients suffering from beta-Thalassemia major with chronic hepatitis C or cirrhosis can be considered safe and effective. Close monitoring for hepatocellular carcinoma development is, in any case, recommended indefinitely post-SVR.

Abstract
European treatment guidelines for hepatitis C virus (HCV) infection recommend that people with genotype (GT) 1a infection and baseline viral load ≤800 000 IU/mL receive elbasvir/grazoprevir (EBR/GZR) for 12 weeks, and those with baseline viral load >800 000 IU/mL receive EBR/GZR plus ribavirin for 16 weeks. This analysis was conducted to clarify whether baseline viral load can serve as an accurate, sensitive or specific stratification factor for defining EBR/GZR regimens. In this post hoc, integrated analysis, participants with GT1a infection who received EBR 50 mg/GZR 100 mg for 12 weeks were stratified according to baseline viral load. Sustained virologic response at 12 weeks post-treatment was achieved by 95.2% (911/957) of participants and was higher among participants with baseline viral load ≤800 000 IU/mL vs >800 000 IU/mL (98.5% vs 93.9%). The 800 000 IU/mL threshold had a positive predictive value of 98.5%, a negative predictive value of 6.1%, a specificity of 91.3%, a sensitivity of 28.4% and an overall accuracy of 31.5%. A baseline viral load cutpoint of 800 000 IU/mL had high positive predictive value and specificity but poor negative predictive value, sensitivity and accuracy in predicting treatment outcomes in this population. Baseline NS5A resistance-associated substitutions (RASs) were detected in 25% (1/4) of virologic failures with baseline viral load ≤800 000 IU/mL and 59.5% (25/42) of those with baseline viral load >800 000 IU/mL. Overall, these data suggest that, compared with the use of a baseline viral load cutpoint, baseline testing for NS5A RASs enables more individuals to receive the 12-week EBR/GZR regimen without compromising the opportunity for SVR.

Abstract
Background: In elderly individuals aged ≥65 years with hepatitis C virus (HCV) infection, efficacious and safe HCV therapy is complicated by frequent comorbidities and concomitant medications. The aim of this analysis was to evaluate the efficacy and safety of elbasvir/grazoprevir (EBR/GZR) in people aged ≥65 years. Methods: This is an integrated retrospective analysis of EBR/GZR administered for 12 weeks in participants with HCV genotype 1 or 4 infection enrolled in 12 Phase 2/3 clinical trials. The primary end point was sustained virologic response 12 weeks after completing therapy (SVR12; HCV RNA below the lower limit of quantification). Results: Most participants aged ≥65 years were receiving ≥1 concomitant medication (322/339; 95.0%) and had ≥1 comorbidity (334/339; 99%). SVR12 rates were 95.3% (323/339) in participants aged ≥65 years and 95.4% (2,041/2,139) in those aged <65 years. Rates of adverse events, drug-related adverse events, serious adverse events, and discontinuations were similar in participants aged ≥65 years and those aged <65 years. In participants aged ≥65 years, median estimated glomerular filtration rate was similar at baseline and at the end of treatment. Conclusion: The efficacy and safety of EBR/GZR were similar in participants with HCV infection aged ≥65 years and those aged <65 years.

Abstract
BACKGROUND AND AIM Although treatment with direct-acting antivirals has dramatically improved morbidity and mortality attributable to chronic hepatitis C virus infection, universal access to these medicines has been slow in the Asia-Pacific region and Russia. This study evaluated efficacy and safety of elbasvir/grazoprevir in participants with hepatitis C virus infection from Asia-Pacific countries and Russia (C-CORAL). METHODS C-CORAL was a phase 3, randomized, placebo-controlled study (NCT02251990). Treatment-naive, HIV-negative, cirrhotic and non-cirrhotic participants with chronic hepatitis C genotype 1, 4, or 6 infection were randomized to elbasvir 50 mg/grazoprevir 100 mg once daily for 12 weeks (immediate-treatment group) or placebo followed by deferred treatment with elbasvir/grazoprevir (deferred-treatment group). The primary efficacy outcome was sustained virologic response at 12 weeks, and the primary safety outcome was a comparison between the immediate-treatment group and placebo phase of the deferred-treatment group. RESULTS A total of 489 participants were randomized (immediate-treatment group, n = 366; deferred-treatment group, n = 123). Sustained virologic response at 12 weeks in the combined immediate/deferred-treatment groups was 94.4% (459/486; 95% confidence interval = 92.4-96.5%). Sustained virologic response at 12 weeks was 98.2% in participants with genotype 1b, 91.9% with genotype 1a, and 66.7% with genotype 6 infection. Similar rates of adverse events and drug-related adverse events were seen in the immediate-treatment group versus placebo phase of the deferred-treatment group (51.0% vs 50.4% and 21.4% vs 21.1%). CONCLUSIONS Elbasvir/grazoprevir for 12 weeks represents an effective and well-tolerated treatment option for treatment-naive people with genotype 1 infection from Asia-Pacific countries and Russia.

Abstract
Context Patients with thalassaemia are at risk of infections such as hepatitis C virus (HCV) due to their repeated blood transfusions; meanwhile, the treatment of thalassaemia patients who had developed HCV infection is a controversial issue. Aims Although the effectiveness of direct-acting antivirals on HCV infection has been confirmed, their side-effects as well as effects on haematological factors due to the resultant need for blood transfusion remain to be further understood. Materials and Methods In this study, 61 patients with major beta thalassaemia and HCV infection, and who had a history of interferon treatment failure were examined. The patients underwent a 24-week treatment with sofosbuvir (SOF) and daclatasvir (DAC). Sustained virological response 12 was used to assess response to treatment. At the end of the study, the need for blood transfusion and serum ferritin was evaluated. Results About 98.4% of the patients responded to the treatment, and only one patient with genotype 1b did not respond positively. No significant complications necessitating treatment cessation were observed, and all the patients tolerated the treatment well. The level of liver enzymes showed a significant reduction 12 weeks after the treatment. The need for blood transfusions in patients before treatment was averagely 1.595 ± 0.65 bag per month, in which 1.593 ± 0.64 bags were received after treatment (P = 0.9). This regimen did not affect the amount of anaemia in patients and did not differentiate the need for blood transfusions. The rate of haemoglobin before treatment was 9.5 ± 1.42 g/dl, which reached 9.6 ± 1.6 g/dl after treatment (P = 0.54). Ferritin levels decreased significantly (from 1948.08 ± 1539.54 to 1315.73 ± 1207.67 ng/ml) (P = 0.001) in the patients after the treatment. Conclusion Combination of SOF and DAC is an effective and tolerable treatment regimen without affect on the amount of anaemia in patients and did not differentiate the need for blood transfusions.

Abstract
The advent of oral direct-acting antiviral agents (DAAs) has dramatically improved the hepatitis C virus (HCV) treatment landscape in the last 4 years, providing cure rates over 95% with a shorter duration of treatment and a very good safety profile. This has enabled access to treatment in nearly all HCV infected patients. The launch of two pangenotypic fixed dose combinations (FDCs) in 2017 made a new step forward in HCV treatment by slightly increasing efficacy and more importantly allowing the treatment of patients without HCV genotyping, and in some cases without fibrosis assessment. However, retreatment of the few DAA failure patients was still an issue for some HCV genotypes. The launch of the triple regimen FDC, sofosbuvir/velpatasvir/voxilaprevir, solves this issue by providing a cure rate over 96% regardless of HCV genotype. In this review, we describe the current HCV treatment landscape and focus on the development of this triple FDC either in treatment-naïve or treatment-experienced patients with previous failure on a DAA regimen.

Abstract
Elbasvir/grazoprevir (EBR/GZR) is an all-oral direct-acting antiviral agent (DAA) with high sustained virologic response (SVR) in clinical trials. This study's primary objective was to evaluate effectiveness of EBR/GZR among HCV-infected patients in a real-world clinical setting. We conducted a nationwide retrospective observational cohort study of HCV-infected patients in the US Department of Veterans Affairs (VA) using the VA Corporate Data Warehouse. The study population included patients with positive HCV RNA who initiated EBR/GZR from February 1 to August 1, 2016. We calculated the 95% confidence interval for binomial proportions for SVR overall and by demographic subgroups. Clinical and demographic characteristics were also evaluated. We included 2436 patients in the study cohort. Most were male (96.5%), African American (57.5%), with mean age of 63.5 (SD = 5.9) and 95.4% infected with genotype (GT) 1 [GT1a (34.7%), GT1b (58.6%)]. Other comorbidities included diabetes (53.2%), depression (57.2%) and HIV (3.0%). More than 50% had history of drug or alcohol abuse (53.9% and 60.5%, respectively). 33.2% of the cohort had cirrhosis. A total of 95.6% (2,328/2,436; 95% CI: 94.7%-96.4%) achieved SVR. The SVR rates by subgroups were: male, 95.5% (2245/2350); female, 96.5% (83/86); GT1a, 93.4%, GT1b, 96.6%, GT4, 96.9%, African American, 95.9% (1,342/1,400); treatment-experienced, 96.3% (310/322); cirrhosis, 95.6% (732/766); stage 4-5 CKD, 96.3% (392/407); and HIV, 98.6% (73/74). SVR rates were high overall and across patient subgroups regardless of gender, race/ethnicity, cirrhosis, renal impairment or HIV. This study provided important data regarding the effectiveness of EBR/GZR in a large clinical setting.

Abstract
OBJECTIVES There is limited data on the efficacy and safety of directly acting antiviral therapy (DAA) for chronic hepatitis C in pediatric population. The aim was to assess the efficacy and safety of DAA in chronic hepatitis C β-thalassemic major pediatric patients. METHODS Prospective study was conducted from September 2015 to January 2017. All β-thalassemic major chronic hepatitis C pediatric patients with age between 5 and 14 years were included in this study. Data related to demography, laboratory parameters, hepatitis C viral load, genotype and outcome of antiviral therapy was analyzed. DAA was planned according to EASL guidelines 2015 for chronic hepatitis C therapy in adults. OBSERVATIONS Fourteen β-thalassemic major patients (median age was 9.5 y, 12 male) were studied. All patients were of genotype 3, received DAA (sofosbuvir 400 mg+daclatasvir 80 mg) for 12 weeks. The median viral load was 2.5×10 IU/mL. End of treatment response and sustained virological response at 12 weeks was achieved in all the patients. Serum alanine aminotransferase, aspartate aminotransferase, ferritin, and albumin significantly reduced after DAA. CONCLUSIONS DAA in adult dosage are safe and effective for treatment of chronic hepatitis C (genotype 3) in pediatric β-thalassemic major population.

Abstract
Treatments for hepatitis C virus (HCV) have advanced greatly, becoming more efficacious with fewer adverse events, due to the availability of direct-acting antiviral agents, which target specific steps in the HCV life cycle. Recently, a combination regimen consisting of the HCV nonstructural protein 5A inhibitor elbasvir (EBR) and the HCV NS3/4A protease inhibitor grazoprevir (GZR) was approved for the treatment of patients with chronic HCV and genotypes (Gts) 1 and 4 in various countries. In Phase III trials, the combination of EBR/GZR (fixed-dose combination table or single agent) for 12 or 16 weeks of treatment with or without ribavirin resulted in a high sustained virological response at 12 weeks in treatment-naïve and treatment-experienced patients with HCV Gt 1a, 1b, 4, or 6, including special populations, such as individuals with advanced chronic kidney disease, HCV-HIV coinfection, and compensated cirrhosis. In this review, we focus on the mode of action, pharmacokinetics, clinical applications, efficacy, and safety profile of EBR/GZR, including special populations who have been considered refractory from the extensive evidence of clinical trials.

Abstract
BACKGROUND In HCV-infected people who fail to achieve sustained virological response after receiving a direct-acting antiviral regimen, virological failure is almost always accompanied by the presence of resistance-associated substitutions (RASs) in the target protein(s). The aim of this long-term observational study was to evaluate the persistence of NS3/4A and NS5A RASs in participants with genotype (GT) 1 infection who relapsed following treatment with a grazoprevir-containing treatment regimen. METHODS RASs were evaluated at baseline (that is, pre-dose on day 1 of the original treatment), at the time of virological failure, and up to follow-up week 96. A total of 58 participants were included. RESULTS In participants treated with elbasvir/grazoprevir ± ribavirin, observed baseline NS3 RASs included 56F, 80K/L, 122N and 170V/I, and observed treatment-emergent NS3 RASs included 36M, 56F/H, 122G, 132I, 156G/I/L/P/T, 168A/E/G/V/Y and 170T. Observed baseline NS5A RASs included 28M/T/V, 30H/R, 31M/V and 93H/N, and treatment-emergent NS5A RASs included 28A/G/S/T, 30H/R, 31M/V and 93H/N/S. Baseline NS3 and NS5A RASs present at time of failure tended to persist during follow-up, and most were detectable for more than 2 years following virological failure. Treatment-emergent NS5A RASs present at time of failure also tended to persist for more than 2 years following virological failure (93%). By contrast, >80% of treatment-emergent NS3 RASs detected at failure had been supplanted by wild type by week 36. CONCLUSIONS Treatment-emergent NS5A RASs can persist for extended periods of time. Retreatment strategies should take account of the presence of these RASs.
