Abstract
Background and Aims Sofosbuvir (S), daclatasvir (D), ledipasvir, or velpatasvir (V) containing first-line hepatitis C virus (HCV) treatment regimens fail to cure viremia in 5-10%. We report our experience of HCV retreatment using these first-line drugs, in a setting where second-line anti-HCV drugs are not available. Methods Adults, who had relapsed after first complete course of a sofosbuvir-containing first-line, pegylated interferon free, anti-HCV treatment regimen with or without ribavirin (Riba) were included. Retreatment regimen, tailored to the failed anti-HCV regimen, was based on principle of using first-line drugs for 24 weeks with ribavirin and swapping between pangenotypic and genotype-specific regimens. Retreatment outcome was categorized as successful (achieved undetectable HCV RNA at the end of treatment [ETR] and sustained viral response at week 12 [SVR12]), non-responder (failed to achieve ETR), or relapse (achieved ETR but not achieved SVR12). Results Twelve patients (9 male; 7 cirrhosis; all genotype 3) who had relapsed to prior anti-HCV treatment (4 SD12, 4 SD24, 1 SDRiba12, 1 SDRiba24, 2 SV12) were included. Following retreatment (2 SDRiba24, 10 SVRiba24), all achieved ETR but only 9 (75%) achieved SVR12. Two among three, in whom retreatment failed, achieved SVR12 following another course of sofosbuvir/velpatasvir/ribavirin for 24 weeks. Overall, 11/12 (92%) patients achieved SVR12 following retreatment with the first-line anti-HCV drugs. Conclusion HCV retreatment could be a treatment option if second-line anti-HCV drugs are not available. Successful retreatment could be achieved, in a large proportion, with the use of first-line drugs for 24 weeks with ribavirin and swapping of pangenotypic/genotype-specific regimens (NCT03483987).

Abstract
BACKGROUND Large-scale real-world data of the 8-week glecaprevir/pibrentasvir (GLE/PIB) therapy for treatment-naïve patients of chronic hepatitis C virus (HCV) infection with compensated cirrhosis is scarce. METHODS The TASL HCV Registry (TACR) is an ongoing nationwide registry program that aims to set up a database and biobank of patients with chronic HCV infection in Taiwan. In this study, data were analyzed as of 31 October 2021 for treatment-naïve HCV patients with compensated cirrhosis receiving 8-week GLE/PIB therapy. Effectiveness reported as sustained virologic response at off-therapy week 12 (SVR12) and safety profiles were assessed. Patient characteristics potentially related to SVR12 were also evaluated. RESULTS Of the 301 patients enrolled, 275 had available SVR12 data. The SVR12 rate was 98.2% (270/275) in the modified intention-to-treat (mITT) population and 89.7% (270/301) in the ITT population. For those mITT patients with genotype 3, FibroScan > 20 kPa, platelet < 150,000/µl, and FibroScan > 20 kPa and platelet < 150,000/µl, the SVR12 rates were 100% (6/6), 100% (12/12), 98.0% (144/147), 100% (7/7), respectively. Overall, 24.9% (75/301) patients experienced adverse events (AEs). The most frequent AEs (> 5%) included fatigue (9.0%) and pruritus (7.0%). Seven (2.3%) patients experienced serious AEs and two (0.7%) resulted in permanent drug discontinuation. None of them were considered as GLE/PIB-related. CONCLUSIONS In this large-scale real-world Taiwanese cohort, 8-week GLE/PIB therapy was efficacious and well tolerated for treatment-naïve compensated cirrhosis patients. SVR12 rates were similarly high as in the clinical trials, including those with characteristics of advanced liver disease.

Factors Associated with Large Renal Function Decline in Patients with Chronic Hepatitis C Successfully Treated with Direct-Acting Antiviral Therapy. Diagnostics (Basel) 2023; 13:diagnostics13030473. [PMID: 36766578 PMCID: PMC9914858 DOI: 10.3390/diagnostics13030473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2022] [Revised: 01/09/2023] [Accepted: 01/16/2023] [Indexed: 02/01/2023] Open
Abstract
The findings regarding changes in renal function in patients with hepatitis C virus (HCV) infection treated with direct-acting antivirals (DAAs) are controversial. This study attempted to identify the factors associated with the large decline in renal function following DAA treatment. This retrospective cohort study included patients treated with DAAs at Chiayi and Yunlin Chang Gung Hospitals, Taiwan, from 1 January 2017 to 31 October 2020. Estimated glomerular filtration rate (eGFR) data were collected within 90 days prior to DAA therapy and 2 years after the confirmation of a sustained virologic response (SVR). We performed multiple logistic regression to evaluate the clinical or laboratory parameters associated with a large eGFR decline (≥10%). Among the enrolled 606 patients, the mean eGFR at the baseline and endpoint were 84.11 ± 24.38 and 78.88 ± 26.30 mL/min/1.73 m2, respectively (p < 0.001). The factors associated with a large eGFR decline 2 years after the SVR included hypertension (OR: 1.481; 95% CI: 1.010-2.173, p = 0.044) and a higher baseline eGFR (OR: 1.016; 95% CI: 1.007-1.024, p < 0.001). A higher albumin level reduced the risk of a large eGFR decline (OR: 0.546; 95% CI: 0.342-0.872, p = 0.011). In the patients with HCV treated with DAAs, a larger renal function decline was more commonly observed in those with hypertension, a lower (but within normal range) albumin level, and a higher baseline eGFR, while DAA treatment had no effect. The clinical significance of these findings has to be further defined. Although some risk factors associated with chronic kidney disease may be alleviated after DAA treatment, the regular control and follow-up of risk factors and renal function are still recommended in at-risk patients after HCV eradication.

SVR achievement in triple therapy treated hepatitis C induced cirrhosis: A dual center retrospective cohort study. Ann Med Surg (Lond) 2022; 80:104193. [PMID: 36045815 PMCID: PMC9422198 DOI: 10.1016/j.amsu.2022.104193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 07/10/2022] [Accepted: 07/10/2022] [Indexed: 11/29/2022] Open
Abstract
Background and objective Multiple prospective and retrospective cohort studies from the West have demonstrated the conflicting results about the efficacy of direct-acting antivirals (DAAs) by sustained virologic response (SVR) achievement rate in hepatitis C virus (HCV) infected patients. But there is limited to no data about the effectiveness of triple therapy ribavirin-sofosbuvir-daclatasvir in cirrhotic hepatitis C infected patients from Pakistan. Methods We conducted a retrospective cohort study by retrieving records of 359 hepatitis C infected patients treated with triple therapy from two tertiary care hospitals in Pakistan [Cirrhotic = 187 (53%); non-cirrhotic = 172 (47%)] from February 18, 2018, to June 29, 2019. We lost the follow-up of 158 (44.1%) patients due to death (n = 24, 6.68%), non-responding/wrong contact number (n = 43, 9.63%), and whom consented to study but didn't complete follow-up/refused to participate in the study (n = 91, 25.34%). Only 201 (45.9%) completed follow up, and of these 87 (43.2%) were cirrhotic patients based on Liver Stiffness Index. Analysis was run by dividing groups into subgroups; who achieved SVR/who didn't achieve SVR. Results We analyzed the data of 201 (45.9%) who completed follow-up including cirrhotic patients (n = 87, 43.2%). Mean age was 50.6 + 10.65 years. 81 (94.18%) did achieve SVR while 5 (5.81%) did not achieve SVR. Achievement of SVR was statistically associated with low platelet count, higher total bilirubin, and lower albumin (p < 0.05) while other demographic and disease-related characteristics of patients were not statistically significant (p > 0.05). Conclusion Triple therapy (ribavirin-sofosbuvir-daclatasvir) achieves over 94% SVR in the Pakistani population, so proved to be highly effective against hepatitis C infection. Triple therapy (ribavirin-sofosbuvir-daclatasvir) achieves over 94% SVR in the Pakistani population. Hence, proven to be highly effective against hepatitis C infection. Achievement of SVR was statistically associated with low platelet count, higher total bilirubin, and lower albumin.

Abstract
An estimated 4.1 million people in the United States are infected with hepatitis C virus (HCV). In 2014, the Hepatitis C Community Alliance to Test and Treat (HepCCATT) collaborative was formed to address hepatitis C in Chicago. From 2014 to 2017, the HepCCATT Case Management Program case managed 181 HCV-infected people and performed on-site capacity building at a 6-site community health center (CHC) that produced codified protocols, which were translated into a telehealth program to build capacity within CHCs to deliver hepatitis C care. HepCCATT's innovative approach to addressing multilevel barriers is a potential model for increasing access to hepatitis C care and treatment.

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
BACKGROUND Direct-acting antivirals (DAA) have dramatically increased HCV cure rates with minimal toxicity in HIV-HCV co-infected patients. This study aimed to compare the socio-behavioral characteristics of patients initiating pegylated-interferon (PEG-IFN)-based HCV treatment with those of patients initiating DAA-based treatment. METHODS ANRS CO13 HEPAVIH is a national multicenter prospective cohort started in 2005, which enrolled 1,859 HIV-HCV co-infected patients followed up in French hospital outpatient units. Both clinical/biological and socio-behavioral data were collected during follow-up. We selected patients with socio-behavioral data available before HCV treatment initiation. RESULTS A total of 580 patients were included in this analysis. Of these, 347 initiated PEG-IFN-based treatment, and 233 DAA-based treatment. There were significant differences regarding patient mean age (45 years±6 for the PEG-IFN group vs. 52 years±8 for the DAA group, p<0.001), unstable housing (21.4% vs. 11.2%, p = 0.0016), drug use (44.7% vs. 29.6%, p = 0.0003), regular or daily use of cannabis (24.3% vs. 15.6%, p = 0.0002), a history of drug injection (68.9% vs 39.0%, p<0.0001) and significant liver fibrosis (62.4% vs 72.3%, p = 0.0293). In multivariable analysis, patients initiating DAA-based treatment were older than their PEG-IFN-based treatment counterparts (aOR = 1.17; 95%CI [1.13; 1.22]). Patients receiving DAA treatment were less likely to report unstable housing (0.46 [0.24; 0.88]), cannabis use (regular or daily use:0.50 [0.28; 0.91]; non-regular use: 0.41 [0.22; 0.77]), and a history of drug injection (0.19 [0.12; 0.31]). CONCLUSION It is possible that a majority of patients who had socio-economic problems and/or a history of drug injection and/or a non-advanced disease stage were already treated for HCV in the PEG-IFN era. Today, patients with unstable housing conditions are prescribed DAA less frequently than other populations. As HCV treatment is prevention, improving access to DAA remains a major clinical and public health strategy, in particular for individuals with high-risk behaviors.

Abstract
Young people in the USA who inject drugs, particularly those at a risk of residence instability, experience the highest incidence of hepatitis C (HCV) infections. This study examined associations between geographic mobility patterns and sociodemographic, behavioral, and social network characteristics of 164 young (ages 18-30) persons who inject drugs (PWID). We identified a potential bridge sub-population who reported residence in both urban and suburban areas in the past year (crossover transients) and higher-risk behaviors (receptive syringe sharing, multiple sex partners) compared to their residentially localized counterparts. Because they link suburban and urban networks, crossover transients may facilitate transmission of HIV and HCV between higher and lower prevalence areas. Interventions should address risk associated with residential instability, particularly among PWID who travel between urban and suburban areas.

Abstract
Approximately three per cent of the world's population (170-200 million people) is chronically infected with hepatitis C virus (HCV) and almost 500,000 people die each year (mostly in lower middle-income countries) from complications secondary to HCV infection. In India, HCV infection imposes a considerable burden of mortality, morbidity and healthcare costs. In the last two decades, the treatment of HCV has evolved from interferon (IFN)-based therapies with or without ribavirin (RBV) to pegylated-IFN (PEG-IFN) and RBV-based therapies that were better tolerated by patients. However, the introduction of oral drugs, which specifically target virus-specific proteins, has now revolutionized the treatment of chronic HCV. These agents are known as direct-acting antivirals (DAAs). These drugs have resulted in very high HCV cure rates even with reduced treatment duration and an excellent tolerability by the patients compared to PEG-IFN- and RBV-based therapies. In India, sofosbuvir (SOF), one of the most effective DAAs, has been made available at a compassionate price; thus only those DAA-based management strategies, which contain SOF are adopted in India. Here, we review different DAAs and their possible roles in different genotypes and stages of liver disease, stressing upon the role of SOF. An attempt has also been made to devise strategies using SOF for the most prevalent genotypes in our country (genotypes 3 and 1) and cirrhosis.

Abstract
BACKGROUND Direct-acting antiviral drugs (DAAs) are favored for the treatment of hepatitis C virus (HCV) infection. However, the experience with the DAAs currently available in India in the treatment of genotype-3 HCV is limited. We therefore reviewed our experience with these drugs in treating patients with chronic genotype-3 HCV infection, including those with cirrhosis. METHODS We prospectively followed adult patients with genotype-3 HCV infection who had received treatment regimens containing sofosbuvir with/without daclatasvir. Patients were categorized as chronic hepatitis C (CHC), compensated cirrhosis (CC), and decompensated cirrhosis (DC). They received either (i) sofosbuvir and ribavirin, with or without pegylated interferon (Peg-IFN) for 12 or 24 weeks, or (ii) sofosbuvir and daclatasvir, with or without ribavirin for 12 or 24 weeks. Response was assessed using HCV RNA testing after 2 or 4 weeks of treatment (rapid virological response [RVR]), at treatment completion (end-of-treatment response [ETR]) or 12 weeks after treatment completion (sustained virological response [SVR12]). RESULTS Of the 160 patients (90% treatment-naïve; CHC 49%, CC 32%, and DC 19%), 39 (24%) received Peg-IFN, sofosbuvir and ribavirin, 21 (13%) received sofosbuvir and ribavirin, and 100 (63%) received sofosbuvir and daclatasvir, with or without ribavirin. On intention-to-treat basis, RVR, ETR, and SVR12 in the entire cohort were 146/160 (91.3%), 151/160 (94.4%), and 147/160 (91.9%), respectively. Seven patients died (CC 2, DC 5) during treatment; four (2 CHC, 2 DC) patients discontinued treatment; and two patients with CC relapsed. CONCLUSIONS Dual-DAA-based regimens were safe and highly effective in treating genotype-3 HCV infection in CHC and CC patients.

Abstract
In recent years, great progress has been made in the field of new therapeutic options for hepatitis C virus (HCV) infection. The new direct-acting antiviral agents (DAAs) represent a great hope for millions of chronically infected individuals because their use may lead to excellent cure rates with fewer side effects. In Latin America, the high prevalence of HCV genotype 1 infection and the significant association of Native American ancestry with risk predictive single-nucleotide polymorphisms (SNPs) in IFNL4 and ITPA genes highlight the need to implement new treatment regimens in these populations. However, the universal accessibility to DAAs is still not a reality in the region as their high cost is one of the major, although not the only, limiting factors for their broad implementation. Therefore, under these circumstances, could the assessment of host genetic markers be a useful tool to prioritize DAA treatment until global access to these new drugs can be achieved? This review will summarize the scientific evidences and the potential implications of HCV pharmacogenomics in this rapidly evolving era of anti-HCV drug development.

Abstract
The aim of the study was to characterize HCV infection in Northwest Spain and assess the impact of the Spanish Strategic Plan to cure HCV infection. Overall, 387 patients were included (60.9% HIV/HCV coinfected and 28.2% cirrhotic). Of these, 72.9% of patients that were recognized as priority for HCV treatment according to the Spanish Strategic Plan (≥F2, transplant or extrahepatic manifestations), initiated treatment during 2015. Globally, SVR12 was achieved in 96.5% of patients. The implementation of the Spanish Strategic Plan has been critical to advance in HCV cure, but 27.1% of priority patients still remain awaiting HCV treatment initiation.

Abstract
BACKGROUND Molecular testing at the point-of-care may turn out to be game changer for HCV diagnosis and treatment monitoring, through increased sensitivity, reduced turnaround time, and ease of performance. One such assay GeneXpert® has recently been released. OBJECTIVES Comparative analysis between performances of GeneXpert® and Abbott HCV-RNA was done. STUDY DESIGN 174 HCV infected patients were recruited and, one time plasma samples from 154 patients and repeated samples from 20 patients, obtained at specific treatment time-points (0, 4, 12 and 24) weeks were serially re-tested on Xpert®. RESULTS Genotype 3 was the commonest, seen in 80 (66%) of the cases, genotype 1 in 34 (28.3%), genotype 4 in 4 (3.3%) and genotypes 2 and 5 in 1 (0.8%) each. Median HCV RNA load was 4.69 log10 (range: 0-6.98log10) IU/ml. Overall a very good correlation was seen between the two assays (R2=0.985), concordance of the results between the assays was seen in 138 samples (89.6%). High and low positive standards were tested ten times on Xpert® to evaluate the precision and the coefficient of variation was 0.01 for HPC and 0.07 for the LPC. Monitoring of patients on two different regimes of treatment, pegylated interferon plus ribavirin and sofosbuvir plus ribavirin was done by both the systems at baseline, 4, 12 and 24 weeks. Perfect correlation between the assays in the course of therapy at different treatment time- point in genotypes 3 and 1 was seen. CONCLUSION The study demonstrates excellent performance of the Xpert® HCV assay in viral load assessment and in treatment course monitoring consistency.

Abstract
Hepatitis C virus (HCV) NS3 protease inhibitors have been primarily designed against genotype 1, the one with the lowest response to dual therapy. However, less evidence of their efficacy on non-1 genotypes is available, and any such information is mostly concentrated on genotypes 2-4. This study evaluated HCV protease resistance profiles in the major six HCV genotypes and identified genetic barrier (GB) profiles to each available protease inhibitor across HCV strains from different locations worldwide. We obtained 15 099 HCV sequences from treatment-naïve subjects retrieved at the Los Alamos HCV Sequence Database. The wild-type codons of different HCV genotypes were used to analyse the smallest number of nucleotide substitution steps required for changing that codon to the closest one associated with drug resistance. The 36L and 175L RAVs were found as genetic signatures of genotypes 2-5, while the 80K RAV was found in all genotype 5 sequences. Genotypes 4 and 6 showed a higher GB to RAV mutations conferring resistance to telaprevir, while genotypes 2-5 presented baseline resistance to that drug, carrying the 36L mutation. Genotype 4 had a higher GB to simeprevir resistance, requiring three substitutions to acquire the 155K mutation. Subtype 1b showed a higher GB than subtype 1a to resistance for most PIs, with RAVs at codons 36 and 155. Geographic disparities were also found in frequencies of certain RAVs in genotypes 2 and 3. Under a scenario of unprecedented evolution of anti-HCV direct-acting agents, the genetic composition of the circulating HCV sequences should be evaluated worldwide to choose the most appropriate/feasible therapeutic schemes with the highest genetic barriers to resistance.

Abstract
Chronic hepatitis C virus (HCV) infection is one of the most common etiologies of liver-related mortality throughout the world. Traditionally, therapy has been focused on pegylated interferon in combination with ribavirin, with clinical trials demonstrating that HCV genotype 1 had the lowest response rate (40-50%), while genotype 3 had an intermediate response rate (60-70%). Recently, significant advances have been made with all-oral direct-acting antiviral (DAA) therapy, which have significantly improved cure rates for HCV genotype 1. Accordingly, HCV genotype 3 is now potentially the most difficult to treat. One of the most potent DAA medications is sofosbuvir, a pan-genotypic nucleotide analogue that inhibits the NS5B polymerase of HCV. Daclatasvir, a pan-genotypic inhibitor of the HCV NS5A replication complex, was recently approved in the United States for treatment of HCV genotype 3 in conjunction with sofosbuvir. This combination may provide a powerful tool in the treatment of HCV genotype 3.

Abstract
Chronic hepatitis C virus (HCV) infection is one of the most common etiologies of liver-related mortality throughout the world. Among the six HCV genotypes, genotype 1 was significantly more aggressive when utilizing the combination of pegylated interferon and ribavirin, as genotype 1-infected patients had the lowest likelihood of achieving cure (40%-50%) and required twice as long duration of treatment, as compared to genotypes 2 and 3. Recently, however, significant advances have been made with the advent of all-oral direct-acting antiviral agents, which have significantly improved the safety, efficacy, and tolerability of the treatment of HCV genotype 1. Among the available treatments for HCV genotype 1, the combination therapy of ledipasvir/sofosbuvir provides several advantages compared to other regimens, including use of a single-pill regimen, possibility to shorten the duration of treatment to 8 weeks, efficacy in patients exposed to protease inhibitors, safety in decompensated cirrhosis, and potential to avoid ribavirin. In this review, we discuss the pharmacotherapy of the combination of ledipasvir/sofosbuvir therapy and summarize the results of the Phase III clinical trials for this treatment in HCV genotype 1 patients. We will also discuss the data for special populations, including decompensated cirrhosis, human immunodeficiency virus (HIV) coinfected patients, African-Americans, the elderly, and those who failed sofosbuvir-containing regimens.

[PMID: 26966547 PMCID: PMC4780041 DOI: 10.1136/bmjgast-2015-000056] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2015] [Revised: 11/24/2015] [Accepted: 12/17/2015] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND High sustained virological response at 12 weeks after end of treatment (SVR12) with 12 weeks of simeprevir and sofosbuvir±ribavirin (SMV+SOF±RBV) has been demonstrated in hepatitis C virus genotype 1 (HCV-1) but is based on limited data. Therefore, we performed a meta-analysis of available data evaluating the effectiveness of SMV+SOF±RBV in HCV-1. METHODS We performed a comprehensive literature search in June 2015 to identify randomised controlled trials (RCTs) and observational studies of HCV-1 patients treated with 12 weeks of SMV+SOF±RBV. Original studies with SVR12 data in ≥5 HCV-1 patients were included. We excluded studies on liver transplant recipients and/or patients co-infected with HIV or hepatitis B/D. We estimated pooled effect sizes using a random-effects model and evaluated heterogeneity with Cochrane Q-test, p≤0.10 and I(2) statistic ≥50%. RESULTS Pooled SVR12 was 85.6% (CI 81.3% to 89.0%) in 1389 HCV-1 patients from 15 studies. On subgroup analysis, SVR12 was 83.9% (CI 79.4% to 87.5%) in observational studies, which was lower than 93.5% (CI 85.7% to 97.2%) in RCTs. A trend showed SVR12 was higher in mild fibrosis, 93.0% (CI 86.2% to 96.6%) compared with advanced fibrosis, 81.5% (CI 75.7% to 86.1%), OR 2.22 (CI 0.79 to 6.25, p=0.131). There was no significant difference in SVR12 rates between HCV-1a, 89.9% (CI 81.9% to 94.6%) and HCV-1b, 89.0% (CI 78.9% to 94.6%) with OR 1.35 (CI 0.75 to 2.42, p=0.322). The most common pooled side effects were: headache 15.2% (n=55/361), fatigue 12.1% (n=78/646), nausea 9.5% (n=50/527) and rash 9.3% (n=68/728). CONCLUSIONS SMV+SOF±RBV is an effective regimen in HCV-1 patients. The SVR12 rate in observational studies was lower than that in RCTs, which may reflect the more diverse patient population in real-world settings.

World J Hepatol 2016; 8:331-339. [PMID: 26962399 PMCID: PMC4766261 DOI: 10.4254/wjh.v8.i6.331] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2015] [Revised: 10/07/2015] [Accepted: 12/23/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate addition of boceprevir to peginterferon/ribavirin (PR) in Russian patients with chronic hepatitis C virus (HCV).
METHODS: Treatment-naive (TN) and treatment-experienced (TE) patients (who had failed prior treatment with PR for ≥ 12 wk) with chronic HCV genotype 1 infection were enrolled in this placebo-controlled, double-blind study. All patients initially received PR for 4 wk. Patients randomized to control treatment then received PR for an additional 44 wk. TN patients randomized to triple therapy received boceprevir (800 mg three times daily) plus PR for 24 wk and then further therapy according to treatment week 8 (TW8) HCV RNA levels. TE patients received boceprevir plus PR for 32 wk and then further therapy according to TW8 HCV RNA levels. Treatment was discontinued for TN patients with detectable HCV RNA at TW24 and TE patients with detectable HCV RNA at TW12 because of futility. The primary efficacy end point was sustained virologic response (SVR) defined as undetectable HCV RNA 24 wk after completing all study therapy.
RESULTS: SVR was 74.8% in the boceprevir plus PR arm compared with 46.2% in the control arm, with a stratification-adjusted treatment difference of 29.2% (95%CI: 16.4-41.5; P < 0.0001). Rates of SVR were higher in the boceprevir arm in both TN and TE patient groups (TN 78.4% vs 56.3%; TE 69.4% vs 30.0%). Within TE patients, the rates of SVR were higher with boceprevir plus PR compared with PR, regardless of treatment failure type (null responder, partial responder, and relapser). Most patients receiving boceprevir plus PR in both TN (86%) and TE (71%) populations were eligible for reduced treatment duration. Anemia was increased in patients receiving boceprevir plus PR vs PR alone (47.2% vs 24.4%); there was a corresponding increase in ribavirin dose reduction and erythropoietin use. Among patients receiving boceprevir plus PR, SVR rates were similar in patients with anemia (< 10 g/dL) and those without anemia (71.2% vs 77.4%).
CONCLUSION: Regulatory approval has been obtained for boceprevir plus PR in Russian patients with HCV genotype 1 infection based on the results of this study.

Abstract
Hepatitis C is a global epidemic. Worldwide, 185 million people are estimated to be infected, most of whom live in low- and middle-income countries. Recent advances in the development of antiviral drugs have produced therapies that are more effective, safer and better tolerated than existing treatments for the disease. These therapies present an opportunity to curb the epidemic, provided that they are affordable, that generic production of these medicines is scaled up and that awareness and screening programmes are strengthened. Pharmaceutical companies have a central role to play. We examined the marketed products, pipelines and access to medicine strategies of 20 of the world's largest pharmaceutical companies. Six of these companies are developing medicines for hepatitis C: AbbVie, Bristol-Myers Squibb, Gilead, Johnson & Johnson, Merck & Co. and Roche. These companies employ a range of approaches to supporting hepatitis C treatment, including pricing strategies, voluntary licensing, capacity building and drug donations. We give an overview of the engagement of these companies in addressing access to hepatitis C products. We suggest actions companies can take to play a greater role in curbing this epidemic: (i) prioritizing affordability assessments; (ii) developing access strategies early in the product lifecycle; and (iii) licensing to manufacturers of generic medicines.

Abstract
Hepatitis C virus (HCV) chronically infects 0.5–3% of the world population. A large group of patients develop cirrhosis and its complications. Since 2011, telaprevir and boceprevir are used, improving the disease evolution. One of the main side effects of these drugs is skin eruption. We report a 53-year-old patient with cirrhosis due to HCV who started the classic treatment associated with telaprevir. In the ninth week, he presented a severe rash that required the interruption of this drug. We emphasize the importance of early recognition and appropriate management of adverse skin reaction.

Validation and Application of a Liquid Chromatography-Tandem Mass Spectrometry Method To Determine the Concentrations of Sofosbuvir Anabolites in Cells. Antimicrob Agents Chemother 2015; 59:7671-9.

Abstract
Sofosbuvir (SOF) is a highly efficacious and well-tolerated uridine nucleotide analog that inhibits the hepatitis C virus (HCV) NS5B polymerase enzyme. SOF is administered as a prodrug, which undergoes intracellular phosphorylation by host enzymes to a monophosphate, diphosphate, and finally a pharmacologically active triphosphate. In order to fully understand the clinical pharmacology of SOF, there is a great need to determine the intracellular phosphate concentrations of the drug. We describe the validation and utilization of a method to characterize SOF's disposition into various in vivo cell types, including hepatocytes, peripheral blood mononuclear cells (PBMC), and red blood cells (RBC). Standard bioanalytical validation criteria were applied to lysed cellular matrices, with a validated linear range of 50 to 50,000 fmol/sample for each phosphate moiety. The assay was utilized to collect the first data demonstrating concentrations of phosphorylated anabolites formed in PBMC, hepatocytes, and RBC in vivo during SOF therapy. Median concentrations in PBMC were 220 (range, 51.5 to 846), 70.2 (range, 25.8 to 275), and 859 (range, 54.5 to 6,756) fmol/10(6) cells in the monophosphate, diphosphate, and triphosphate fractions, respectively. In contrast, RBC triphosphate concentrations were much lower than those of PBMC, as the median concentration was 2.91 (range, 1.14 to 10.4) fmol/10(6) cells. The PBMC triphosphate half-life was estimated at 26 h using noncompartmental approaches, while nonlinear mixed-effect modeling was used to estimate a 69 h half-life for this moiety in RBC. The validated method and the data it generates provide novel insight into the cellular disposition of SOF and its phosphorylated anabolites in vivo.

Abstract
Hepatitis C infection can lead to cirrhosis and hepatocellular carcinoma and it is an important cause of mortality and morbidity. Achieving a sustained virological response has been the major aim for decades. Interferon treatment was the primarily developed therapy against the infection. Addition of the guanosine analog ribavirin to stop viral RNA synthesis increased the response rates as well as the adverse effects of the treatment. The increasing demands for alternative regimens led to the development of direct-acting antivirals (DAAs). The approval of sofosbuvir and simeprevir signaled a new era of antiviral treatment for hepatitis C infection. Although the majority of studies have been performed with DAAs in combination with interferon and resulted in a decrease in treatment duration and increase in response rates, the response rates achieved with interferon-free regimens provided hope for patients ineligible for therapy with interferon. Most DAA studies are in phase II leading to phase III. In the near future more DAAs are expected to be approved. The main disadvantage of the therapy remains the cost of the drugs. Here, we focus on new treatment strategies for hepatitis C infection as well as agents targeting hepatitis C virus replication that are in clinical development.

Abstract
Progress in medicine goes along with an exponential growth of the cost of drugs and devices. While any person has the right to obtain the best possible benefit from medical care, a state needs to strike a balance between granting the optimal personal benefit to each individual and the needs of the society as a whole. Health systems in all countries therefore are facing a huge problem of distributive justice, as while they should guarantee individual rights, among which the right to health in its broader sense, including physical, psychological and social well-being (therefore not limited to healing, but extending to compliance and quality of life), they must also grant equal access to the healthcare resources and keep the distribution system sustainable.

Abstract
Aims. To measure the expression of activin βA-subunit, activin IIA and IIB receptors, Smad4, Smad7, and follistatin in the liver and the liver and serum concentrations of mature activin-A and follistatin in normal rat following treatment with pegylated interferon-α (Peg-INF-α) and ribavirin (RBV). Materials and Methods. 40 male Wistar rats were divided equally into 4 groups: “control,” “Peg-only” receiving 4 injections of Peg-INF-α (6 µg/rat/week), “RBV-only” receiving ribavirin (4 mg/rat/day) orally, and “Peg & RBV” group receiving both drugs. The expression of candidate molecules in liver was measured by immunohistochemistry and quantitative PCR. The concentrations of mature proteins in serum and liver homogenate samples were measured using ELISA. Results. Peg-INF-α ± RBV altered the expression of all candidate molecules in the liver at the gene and protein levels (P < 0.05) and decreased activin-A and increased follistatin in serum and liver homogenates compared with the other groups (P < 0.05). There were also significant correlations between serum and liver activin-A and follistatin. Conclusion. Peg-INF-α modulates the hepatic production of activin-A and follistatin, which can be detected in serum. Further studies are needed to explore the role of Peg-INF-α on the production of activins and follistatin by the liver and immune cells.

Abstract
Pegylated-interferon-α based therapy for the treatment of chronic hepatitis C (CHC) is considered suboptimal as not all patients respond to the treatment and it is associated with several side effects that could lead to dose reduction and/or termination of therapy. The currently used markers to monitor the response to treatment are based on viral kinetics and their performance in the prediction of treatment outcome is moderate and does not combine accuracy and their values have several limitations. Hence, the development of new sensitive and specific predictor markers could provide a useful tool for the clinicians and healthcare providers, especially in the new era of interferon-free therapy, for the classification of patients according to their response to the standard therapy and only subscribing the novel directly acting antiviral drugs to those who are anticipated not to respond to the conventional therapy and/or have absolute contraindications for its use. The importance of activins and follistatin in the regulation of immune system, liver biology, and pathology has recently emerged. This review appraises the up-to-date knowledge regarding the role of activins and follistatin in liver biology and immune system and their role in the pathophysiology of CHC.
