Abstract
Direct-acting antiviral (DAA)-induced HCV clearance conceivably leads to improved outcomes at all stages of liver disease. However, available data suggest that the maximum measurable benefit is obtained by treating patients before they reach the stage of compensated advanced chronic liver disease (cACLD). Ideally, all patients with chronic hepatitis C should be treated before they develop advanced fibrosis or cirrhosis, since even if sustained virologic response (SVR) reduces the risk of hepatic events (e.g. decompensation and hepatocellular carcinoma [HCC]) and improves survival, further progression of liver disease and adverse outcomes, including hepatic deaths, cannot be entirely avoided. The hepatic venous pressure gradient (HVPG) correlates closely with the stage of liver disease. Measurements of HVPG in patients with severe fibrosis or cirrhosis treated with DAAs show that those with the highest degree of portal hypertension have the lowest probability of a meaningful reduction of portal pressure after SVR, and remain at significant risk of decompensation. Reduced liver stiffness is commonly observed in patients with cACLD but its role in predicting prognosis is yet to be demonstrated. In patients with decompensated cirrhosis, prevention of further decompensation and of HCC is only weakly associated with SVR. Overall, the main clinical predictors of a high risk of HCC in patients who obtain SVR on DAAs are all indexes strongly reflecting advanced fibrosis and impaired hepatic function. Long-term follow-up of large real-life cohorts of patients treated at all stages of liver disease, but mainly those with mild to moderate fibrosis, will be needed to confirm the impact of SVR among diverse HCV-infected populations and, more importantly, to better stratify patients at higher risk of complications in order to define their correct surveillance.

Hepatic Fat-Genetic Risk Score Predicts Hepatocellular Carcinoma in Patients With Cirrhotic HCV Treated With DAAs. Hepatology 2020; 72:1912-1923. [PMID: 32762045 DOI: 10.1002/hep.31500] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 05/28/2020] [Accepted: 07/07/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS Genetic factors and steatosis predispose to hepatocellular carcinoma (HCC) in patients with chronic hepatitis C virus; however, their impact in patients with cirrhosis cured by direct-acting antivirals (DAAs) is still undefined. We assessed the association between a genetic risk score (GRS) of hepatic fat accumulation, combining variants in PNPLA3 (patatin-like phospholipase domain containing 3), MBOAT7 (membrane bound O-acyltransferase domain containing 7), TM6SF2 (transmembrane 6 superfamily member 2), GCKR (glucokinase regulator), and HCC in patients treated with DAAs. APPROACH AND RESULTS We considered 509 consecutive patients with HCV cirrhosis (defined histologically or when liver stiffness ≥12 kPa) treated with DAAs. HCC was diagnosed according to international recommendations. GRS was calculated from the weighted impact of single variants on hepatic fat content quantified by H1 spectrometry in the general population (Dallas Heart Study). During a median follow-up of 43 (3-57) months after DAA start, 36 of 452 (8%) patients developed de novo HCC, 4-year cumulative probability being 9% (95% confidence interval 7%-12%). Male sex (hazard ratio [HR] 2.54, P = 0.02), diabetes (HR 2.39, P = 0.01), albumin (HR 0.35, P = 0.001), and GRS score >0.597 (HR 2.30, P = 0.04) were independent predictors of de novo HCC. In contrast, single genetic risk variants were not useful in stratifying HCC risk. The proportion of patients who developed HCC according to the combination of the independent risk factors ranged from 11% to 67%. HCC recurred in 28 of 57 (49%) patients with previous history; diabetes and ethnicity were the only independent predictors of HCC recurrence. CONCLUSIONS In a large cohort of DAA-treated patients with cirrhotic HCV, GRS was associated with de novo HCC independently of classical risk factors, including liver disease severity. These data suggest that hepatic fat (i.e., lipotoxicity) promotes HCC in this setting and may represent a target for chemoprevention. Combination of clinical and genetic predictors may improve HCC risk stratification.

Abstract
Emerging hepatocellular carcinoma (HCC) has been sequentially reported in chronic hepatitis C virus (HCV) treated with direct-acting antivirals (DAAs). Homeobox transcript antisense RNA (HOTAIR), an oncogene, has been reported to be associated with cancer. We investigated the predictive value of lnc-HOTAIR for HCC surveillance in chronic HCV patients following DAAs therapy. The expression levels of lnc-HOTAIR and ATG-7 genes were measured in 220 with chronic HCV, following a DAAs based therapy for 12 weeks, the patients were followed-up for attentive surveillance of HCC for 12 months after starting DAAs. In terms of lnc-HOTAIR, patients with HCC and high viral load had significantly higher median expression levels of HOTAIR of (68 vs. 24; p = .001) and (94 vs. 52; p = .001), respectively. Moreover, the median expression level of ATG-7 was higher in those who developed HCC (114 vs. 51; p = .001). The expression of lnc-HOTAIR and ATG-7 are significant predictors of the development of HCC in HCV-4 infected patients treated with DAAs, with a cut-off value of 37 and 86, respectively. The increased expression levels of lnc-HOTAIR more than 68 in HCC patients following DAAs were correlated with poorer disease outcomes compared to those with lower expression levels; however, ATG-7 expression levels more than 114 were correlated with worse overall survival but not the progression-free one. We suggest that high expression levels of lnc-HOTAIR could serve as a risk assessment biomarker for HCC before and during DAAs course therapy in Chronic HCV-4 patients, and should be rigorously taken into consideration before DAAs.

Hepatitis C-related cirrhosis will be a marginal cause of hospital admissions by 2025. J Hepatol 2020; 73:1360-1367. [PMID: 32697948 DOI: 10.1016/j.jhep.2020.07.018] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 07/03/2020] [Accepted: 07/14/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND & AIMS Complications of cirrhosis are the main cause of hospital admissions in liver units. In areas where HCV is prevalent, most of these admissions are attributable to HCV-related cirrhosis (HCV-cirrhosis). This study assessed the impact of direct-acting antivirals (DAA) in the profile of patients with liver disease admitted to a referral liver unit from a university hospital. METHODS We registered hospital admissions resulting from cirrhosis to the Liver Unit of the Hospital Clinic of Barcelona, from 2011 to 2014 (pre-DAA period) and from 2015 to 2019 (post-DAA period). RESULTS From a total of 14,865 hospital admissions, 10,053 resulted from cirrhosis (corresponding to 6,272 patients). The number and proportion of hospital admissions because of HCV-cirrhosis remained stable during the period 2011-2014 (525 per year, 48.8% of the total), but decreased progressively after 2015 (p <0.001), reaching <300 (27.1%) admissions in 2019. Similarly, HCV-cirrhosis accounted for 3,885 inpatient days per year (44.9%) during the pre-DAA period and decreased steadily after 2015 (p >0.001), reaching only 1,909 inpatient days (22%) in 2019. The figures for intensive care unit admissions followed a similar pattern. By means of a slope analysis (binomial regression model), we predicted that HCV-cirrhosis hospital admissions will be residual by 2025 (2.3%, 95% CI 0-10.9%). By contrast, we observed a significant increase in hospital admissions because of metabolic-associated fatty liver disease (5-fold) and autoimmune hepatitis (4-fold) during the study period. CONCLUSIONS In summary, our data showed a profound reduction in HCV-cirrhosis hospitalisation burden since 2015, coincident with the wide use of DAAs in Spain. Our predictions suggest that, by 2025, HCV-cirrhosis will be a marginal cause of hospital admissions for patients with liver disease. LAY SUMMARY Over the past few years, the wide use of antiviral drugs that cure HCV has had a significant effect on patients being admitted to hospital. Most patients with HCV and cirrhosis are treated (and often cured) in the community and, thus, the number of hospital admissions because of severe forms of HCV has decreased drastically. HCV is no longer the first cause of admission into liver units and, in only a few years from now, it is likely to be only a residual cause of hospitalisation.

Abstract
BACKGROUND Despite efficacy in HCV eradication, direct-acting antiviral (DAA) therapy has raised controversies around their impact on hepatocellular carcinoma (HCC) incidence. Herein we reported the first Australian data on HCC incidence in DAA-treated HCV patients with advanced fibrosis/cirrhosis. METHODS We conducted a retrospective single center study of DAA-treated HCV patients with advanced fibrosis/cirrhosis from April 2015 to December 2017. Patients with prior HCC were included if they had complete response to HCC treatment. RESULTS Among 138 patients who completed DAA therapy, 133 (96.4%) achieved sustained virologic response (median follow-up 23.8 months). Ten had prior HCC and 5/10 (50.0%) developed recurrence, while de novo HCC developed in 7/128 (5.5%). Median time from DAA to HCC diagnosis was 34 weeks in recurrent HCC vs. de novo 52 weeks (P = 0.159). In patients with prior HCC, those with recurrence (vs. without) had shorter median time between last HCC treatment and DAA (12 vs. 164 weeks, P < 0.001). On bivariate analysis, failed sustained virologic response at 12 weeks (SVR12) (P = 0.011), platelets (P = 0.005), model for end-stage liver disease (MELD) score (P = 0.029), alpha fetoprotein (AFP) (P = 0.013), and prior HCC (P < 0.001) were associated with HCC post-DAA. On multivariate analysis, significant factors were prior HCC (OR = 4.80; 95% CI: 1.47-48.50; P = 0.010), failed SVR12 (OR = 2.83; 95% CI: 1.71-16.30; P = 0.016) and platelets (OR = 0.97; 95% CI: 0.95-0.99; P = 0.009). CONCLUSIONS Our study demonstrates a high incidence of recurrent HCC in HCV patients with advanced fibrosis/cirrhosis treated with DAA. Factors associated with HCC development post-DAA were more advanced liver disease, failed SVR12 and prior HCC, with higher rates of recurrence in those who started DAA earlier.

World J Gastroenterol 2020; 26:6770-6781.

Abstract
Direct acting antivirals (DAAs) have revolutionized the treatment of hepatitis C virus (HCV) infection, achieving high rates (≥ 95%) of sustained virological response, with a good safety profile and high compliance rates. Consequently, it had been expected that viral clearance will reduce morbidity and mortality rates, as well as the risk of hepatocellular carcinoma (HCC). However, since 2016, concerns have been raised over an unexpected high rate of HCC occurrence and recurrence after DAA therapy, which led to an avalanche of studies with contradictory results. We aimed to review the most recent and relevant articles regarding the risk of HCC after DAA treatment and identify the associated risk factors.

Hepatocellular Carcinoma Risk According to Regimens for Eradication of Hepatitis C Virus; Interferon or Direct Acting Antivirals. Cancers (Basel) 2020; 12:E3414. [PMID: 33217965 PMCID: PMC7698608 DOI: 10.3390/cancers12113414] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 11/09/2020] [Accepted: 11/16/2020] [Indexed: 12/11/2022] Open
Abstract
By pegylated interferon (PegIFN)-free direct-acting antivirals (DAAs) against hepatitis C virus (HCV) infection, a sustained virological response (SVR) rate >95% can be attained with a satisfactory tolerability and shorter treatment duration. However, it remains controversial whether there is any difference in prognosis depending on regimens-PegIFN or DAAs. We compared the probabilities of hepatocellular carcinoma (HCC) development between patients achieving an SVR by PegIFN/ribavirin (PegIFN group, n = 603) and DAAs (DAAs group, n = 479). The DAAs group was significantly older and had a higher proportion of cirrhosis than the PegIFN group. Before adjustment, the DAAs group had a higher HCC incidence than the PegIFN group (p < 0.001). However, by multivariate analyses, the DAAs (vs. PegIFN) group was not associated with HCC risk (adjusted hazard ratio 0.968, 95% confidence interval 0.380-2.468; p = 0.946). Old age, male, higher body mass index, cirrhosis, and lower platelet count were associated with increased HCC risk (all p < 0.05). After propensity score matching (PSM), a similar HCC risk between the two groups was observed (p = 0.372). We also compared HCC incidences according to sofosbuvir (SOF)-based and SOF-free DAAs, showing a similar risk in both groups before adjustment (p = 0.478) and after PSM (p = 0.855). In conclusion, post-SVR HCC risks were comparable according to treatment regimens; PegIFN- vs. DAA-based regimens and SOF-based vs. SOF-free DAA regimens. Further studies with a longer follow-up period are required.

MTHFR rs1801133 Polymorphism Is Associated With Liver Fibrosis Progression in Chronic Hepatitis C: A Retrospective Study. Front Med (Lausanne) 2020; 7:582666. [PMID: 33304912 PMCID: PMC7691664 DOI: 10.3389/fmed.2020.582666] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Accepted: 10/12/2020] [Indexed: 12/26/2022] Open
Abstract
Background: The MTHFR (methylenetetrahydrofolate reductase) rs1801133 polymorphism leads to higher circulating levels of homocysteine, which is related to several liver diseases. We aimed to evaluate the relationship between MTHFR rs1801133 polymorphism and liver fibrosis progression in HCV-infected patients. Methods: We conducted a preliminary retrospective cohort study in 208 non-cirrhotic HCV-infected patients. These subjects had at least two liver stiffness measurements (LSM), which were assessed using transient elastography, and no patient had cirrhosis at baseline. We analyzed the association between MTHFR rs1801133 and outcome variables using Generalized Linear Models. Results: HCV-infected patients were 47 years old, around 54% were males, a low frequency of high alcohol intake (13.5%) or prior use of intravenous drugs (10.1%). A total of 26 patients developed cirrhosis (LSM1 ≥ 12.5) during a median follow-up of 46.6 months. The presence of the rs1801133 C allele showed an inverse association with the LSM2/LSM1 ratio (adjusted AMR = 0.90; 95%CI = 0.83-0.98; p = 0.020) and the cirrhosis progression (adjusted OR = 0.43; 95%CI = 0.19-0.95; p = 0.038). Besides, rs1801133 CT/CC genotype had an inverse association with the LSM2/LSM1 ratio (adjusted AMR = 0.80; 95%CI = 0.68-0.95; p = 0.009) and the cirrhosis progression (adjusted OR= 0.21; 95%CI = 0.06-0.74; p = 0.015). Conclusions: MTHFR rs1801133 C allele carriers presented a diminished risk of liver fibrosis progression and development of cirrhosis than rs1801133 T allele carriers. This statement supports the hypothesis that MTHFR rs1801133 polymorphism appears to play a crucial role in chronic hepatitis C immunopathogenesis.

Abstract
Background Direct-acting antivirals (DAAs) have revolutionized the treatment of hepatitis C virus (HCV). The impact of DAAs on recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) remains uncertain. Objective We aimed to evaluate the risk of HCC recurrence in LT recipients cleared of HCV with DAAs at the time of LT compared to a control group of LT recipients who were viremic at the time of LT. Methods The study was a single-center, retrospective cohort study of patients undergoing LT for HCV-related HCC from 2002 to 2017. We compared time to post-LT HCC recurrence in patients with a sustained virological response (SVR) from DAAs prior to LT (DAA group) to patients who were viremic at LT (HCV+ group) using Kaplan-Meier analysis. We performed a secondary analysis comparing post-LT HCC recurrence in the DAA group to LT recipients with SVR from interferon-based treatment prior to LT (IFN group). Results One hundred fifty-one patients underwent LT for HCC related to HCV: 34 patients in DAA group, 95 patients in HCV+ group, and 22 in IFN group. Kaplan-Meier estimates of being HCC free were 96.2, 96.2, and 78.8% at 6, 12, and 24 months in DAA group, respectively, and 100, 98.6, and 95.8% at 6, 12, and 24 months in the HCV+ group, respectively; p = 0.08. There was no difference observed for HCC recurrence between the DAA and IFN groups. In a multivariate Cox proportional hazards model, DAA use increased the risk of post-LT HCC recurrence (HR 5.2, 95% CI 0.9-29.81, p = 0.07). Conclusions A strong trend was observed on both Kaplan-Meier and multivariate analyses toward increased post-LT HCC recurrence in patients who achieved SVR prior to LT with DAAs compared to patients who were viremic at LT. Caution is required when considering pre-LT treatment of HCV with DAAs in patients with HCC.

Abstract
Suspect has been directed towards some direct acting antivirals (DAAs) due to their reported association with hepatocellular carcinoma (HCC) development in chronic hepatitis C (CHC) patients. The mechanisms behind HCC development, following CHC treatment, were not well understood and may be linked to genetic variabilities in different patients which affect several cytokine productions involved in angiogenesis and inflammation. Of these variabilities, is the genetic polymorphisms in the interleukin-17 (IL-17) A receptor gene. Being an important pleiotropic cytokine, this study aimed to investigate the association between haplotypes in IL-17A receptor rs2275913 and rs3819024 and development of HCC in CHC patients treated with either triple therapy (sofosbuvir (SOF), pegylated interferon-alpha-2a (Peg-IFNα-2a) & ribavirin(RBV)) or with dual therapy (Peg-IFNα-2a&RBV). A cohort of 100 CHC patients was recruited in this study. Samples were tested for single nucleotide polymorphism (SNPs) in IL-17A receptor (rs2275913 and rs3819024) using TaqMan Genotyping assay. Our results showed that the presence of G-G haplotype in IL-17A (rs2275913& rs3819024) is inversely associated with HCC development in patients receiving triple therapy. While, high serum AFP levels are directly associated with HCC development in patients receiving triple therapy. However, in patients receiving dual therapy, HCC development was only associated with high serum alpha fetoprotein (AFP) levels and was not correlated to any specific allele in our studied SNPs. Such results highlight the importance of IL17A receptor gene haplotyping in the prediction of HCC development in patients receiving triple therapy. These results will aid in performing tailored, personalized strategy for CHC treatment.

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
BACKGROUND/PURPOSE De novo and early recurrent hepatocellular carcinoma (HCC) have been observed in clinical practice after direct antiviral agents (DAA) treatment. The study aims to investigate the change of cytokines and growth factors after hepatitis C virus (HCV) clearance by DAAs and their impact on the risk of HCC development. METHODS The chronic hepatitis C (CHC) patients with or without HCC who received DAA treatment were prospectively enrolled. The cytokines and growth factors were measured using Bio-Plex Pro™ Human Cytokine 27-plex Assay before and 12 weeks off DAA treatment. RESULTS A total of 37 patients were enrolled for final analysis. There were 11 males (29.7%) and 26 females (70.3%). The mean age was 67.39 ± 10.48 years. 11 (29.7%) patients were HCV-related HCC patients. The HCV genotype included genotype 2 in 26 patients and genotype 1b in 10 patients, and genotype 6 in 1. Among them, 35 (94.6%) patients achieved sustained virologic response (SVR). Two patients with HCC failed to DAA treatment. In HCV-related HCC patients, serum IP-10 level significantly declined after HCV clearance, but no difference in five growth factors including G-CSF, GM-CSF, basic FGF, PDGF-BB, and VEGF. Several cytokines including IP-10 significantly declined after HCV clearance in CHC patients. CONCLUSION This study showed only serum IP-10 level, a risk factor of HCC, was significantly declined after HCV clearance and no change in the markers of growth factors in HCV-related HCC patients, suggesting no promotion of HCC using DAA treatment for HCV-related HCC patients.

Abstract
BACKGROUND This 5-year follow-up of the CCgenos cross-sectional study aimed to observe real-life outcomes in a cohort of 997 Han Chinese patients with chronic HCV infection and to explore the impacts of HCV genotype, patient characteristics and treatment status. METHODS Clinical information and centralized HCV RNA measures were collected every 6/3 months for untreated/treated patients. Overall disease progression was defined as ≥1 of: de novo development of cirrhosis, Child-Turcotte-Pugh score increased by ≥2 points (if cirrhosis at baseline), progression to decompensated cirrhosis, hepatocellular carcinoma (HCC), liver transplant or death. Cox regression assessed risk factors for the time from estimated infection to cirrhosis or HCC. Logistic regression assessed risk factors for incidence rates of cirrhosis and overall disease progression. RESULTS 281 of 514 patients enrolled across China completed 5 years of follow-up. Overall disease progression occurred in 36/364 (9.9%) treated patients and 35/148 (23.6%) untreated patients (odds ratio = 0.35; 95% CI 0.21, 0.59; P<0.0001). Overall disease progression occurred in 6/231 (2.6%) patients achieving sustained virological response at 24 weeks (SVR24) versus 11/82 (13.4%) who did not (P=0.0002). Cirrhosis development was significantly associated with abnormal aspartate aminotransferase (AST), age ≥40 years, body mass index ≥28 kg/m2, HCV GT1, platelet count <100×109/l, and AST to platelet ratio index (APRI) ≥2 (multivariate Cox regression, P<0.05). HCC was significantly associated with HCV GT1 and platelet count <100×109/l (multivariate Cox regression, P<0.05). CONCLUSIONS Achieving SVR24 significantly reduced the probability of overall disease progression but no significant difference was seen for both cirrhosis and HCC during 5 years of follow-up.

Abstract
Hepatitis C virus (HCV) is a global viral widespread without an available vaccine to prevent infection. HCV infection can cause serious liver diseases such as hepatocellular carcinoma (HCC). Current treatment of HCV infection depends on the FDA approved direct-acting antivirals (DAAs) which have side effects and expensive. Thus, development of a novel, more efficient, along with affordable pricing anti-HCV agents is still required. The purpose of the present study is to evaluate the antiviral effects of bee venom (BV) from the honeybee Apis mellifera on the HCV replication life cycle. The crude venom and its components were examined for their anti-HCV activities using Huh7it-1 cultured cells and the JFH1 strain of HCV genotype 2a. Results revealed that BV inhibited HCV infection with 50% inhibitory concentration (IC50) of 0.05 ng/ml, while the 50% cytotoxic concentration (CC50) being 20,000 ng/ml. The venom directly blocked HCV/cell entry by acting on virus particles in a dose dependent manner, whereas no interference on the host cells. Furthermore, venom showed no inhibitory effect on HCV replication and release. Interestingly, none of the main BV components including the mast cell degranulating peptide (MCD), mpamin, or the small peptides melittin (MLT) showed anti-HCV activity up to 5 μg/ml. In conclusion, these results suggest that BV has a direct virucidal activity against HCV and may exert its antiviral effect through a non-common peptide(s) or toxin complex within the crude venom. Therefore, the crude BV can be considered as a promising candidate for characterization and development of new and natural anti-HCV therapeutic agents.

Decrease in Chitinase 3-Like Protein 1 Levels Reflects Improvement in Liver Fibrosis after HCV Eradication. DISEASE MARKERS 2020; 2020:8539804. [PMID: 33082884 PMCID: PMC7556050 DOI: 10.1155/2020/8539804] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/22/2019] [Revised: 08/20/2020] [Accepted: 09/05/2020] [Indexed: 12/13/2022]
Abstract
Aim The success of direct-acting antivirals (DAAs) against hepatitis C virus is a major breakthrough in hepatology. Previous studies have shown that chitinase 3-like protein 1 (CHI3L1) was a marker for staging of liver fibrosis caused by HCV. In this investigation, we used CHI3L1 as a surrogate marker to compare dynamic hepatic fibrosis variations following the elimination of HCV among cases receiving sofosbuvir (SOF)-based regimens and pegylated interferon/ribavirin (PR) treatments. Methods The study enrolled 105 patients, including 46 SOF-based regimens treated patients, 34 PR-experienced patients, and 25 untreated patients. Serum samples and clinical data were obtained at the baseline, the end of treatment, and at weeks 24 and 48 after treatments. Results First, we found that serum level of CHI3L1 correlated moderately but significantly with LSM (r = 0.615, P < 0.001) at the baseline, and diagnosed liver cirrhosis at baseline with high accuracy (AUC = 0.939) by ROC analysis. So we explored CHI3L1 as a sensitive biomarker to monitor the regression of liver fibrosis after HCV eradication. We found that the serum CHI3L1 level of CHC cases receiving SOF-based regimen treatments was markedly reduced immediately after treatment compared with that at the baseline (123.79 (118.55) vs. 118.20 (103.68), P = 0.001). For cases undergoing PR treatment, the serum CHI3L1 decreased significantly at week 24 posttreatment compared with that at the baseline (69.98 (51.44) vs 89.15 (110.59), P = 0.016). For the untreated cirrhotic patients, CHI3L1 levels increased at week 96 follow-up compared with that at the baseline (194.73 (172.46) vs. 89.50 (242.97), P = 0.048), reflecting continued worsening of liver fibrosis. Conclusion CHI3L1 is suggested to be the sensitive marker to monitor fibrosis variations in weeks during treatments and after achieving SVR. It has the potential to allow the identification of early treatment failure for a timely switch to alternative treatment and to allow monitoring progression of fibrosis as a risk factor for liver cirrhosis.

Abstract
AIM It remains unclear how direct-acting antiviral (DAA) treatments influence hepatocellular carcinoma (HCC) recurrence and survival in comparison with interferon (IFN). METHODS In total, 338 patients with chronic hepatitis C virus (HCV) infection and previous HCC treatments who initiated IFN (N = 88, IFN group) or DAA treatment (N = 250, DAA group) from January 2005 to November 2017 at 23 hospitals and achieved sustained virologic response (SVR) were analyzed. Cumulative HCC recurrence and survival rates were compared between the two groups using propensity score (PS) matching. RESULTS After PS matching, 63 patients were selected for each group. The cumulative HCC recurrence rates at 1 and 3 years were 20.6% and 34.6% in the IFN group and 19.2% and 43.0% in the DAA group, respectively; the difference in cumulative HCC recurrence rates between the two groups was not significant (P = 0.332). No significant differences in HCC recurrence patterns were observed between the two groups. Overall survival rates at 1 and 3 years were 100% and 96.6% in the IFN group and 100% and 96.4% in the DAA group, respectively; the difference in overall survival rates between the two groups was not significant (P = 0.132). No significant differences in HCC recurrence and overall survival rates were observed between the two groups in subgroup analyses of patients receiving curative treatment (liver resection or radiofrequency ablation) for the most recent HCC before HCV treatment. CONCLUSIONS The recurrence rates and patterns of HCC and overall survival rates do not differ between SVR patients receiving IFN and DAA treatments.

Clinical efficacy of direct-acting antiviral therapy for recurrent hepatitis C virus infection after liver transplantation in patients with hepatocellular carcinoma. World J Hepatol 2020; 12:628-640. [PMID: 33033569 PMCID: PMC7522560 DOI: 10.4254/wjh.v12.i9.628] [Citation(s) in RCA: 2] [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: 03/09/2020] [Revised: 06/03/2020] [Accepted: 08/16/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Recurrent hepatitis C virus (HCV) infection of transplanted liver allografts is universal in patients with detectable HCV viremia at the time of transplantation. Direct-acting antiviral (DAA) therapy has been adopted as the standard of care for recurrent HCV infection in the post-transplant setting. However, there are insufficient data regarding its efficacy in liver transplant (LT) recipients with a history of hepatocellular carcinoma (HCC), and the risk of HCC recurrence after DAA therapy is unknown.
AIM To demonstrate predictors of DAA treatment failure and HCC recurrence in LT recipients.
METHODS A total of 106 LT recipients given DAAs for recurrent HCV infection from 2015 to 2019 were identified (68 with and 38 without HCC). Descriptive statistics and logistic regression models were used to estimate the multivariate odds ratios and respective 95% confidence intervals for predictors of treatment failure and HCC recurrence.
RESULTS Six patients (6%) experienced DAA therapy failure post-LT and 100 (94%) had a sustained virologic response at follow-up week 12. A high alanine transaminase level > 35 U/L at treatment week 4 was a significant predictor of treatment failure. Relapse to pre-LT DAA therapy is a predictor of post-LT HCC recurrence, P = 0.04. DAA relapse post-LT was also associated with post-transplantation HCC recurrence, P = 0.05.
CONCLUSION DAAs are effective and safe in the treatment of recurrent HCV infection in LT recipients with history of HCC. Relapse to pre- and post-LT DAA therapy is associated with post-transplantation HCC recurrence.

Direct Antiviral Treatments for Hepatitis C Virus Have Off-Target Effects of Oncologic Relevance in Hepatocellular Carcinoma. Cancers (Basel) 2020; 12:cancers12092674. [PMID: 32961688 PMCID: PMC7565876 DOI: 10.3390/cancers12092674] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 09/14/2020] [Accepted: 09/15/2020] [Indexed: 12/25/2022] Open
Abstract
Simple Summary Hepatitis C virus (HCV) eradication by direct-acting antiviral agents (DAAs) reduces de novo hepatocellular carcinoma incidence in cirrhosis; however, contrasting evidence on higher incidence of hepatocellular carcinoma (HCC) was reported in patients previously treated for HCC. Here, we showed that sofosbuvir and daclatasvir can modulate cell proliferation, invasion capability and gene expression in HCC-derived cell lines, suggesting that off-target effects of these drugs might be responsible for both the increase and reduction of cell proliferation and migration capability. Off-target gene modulation, mainly affecting mitochondrial functions, ribosomal genes and histones, was consistent with matched phenotypic changes and might account either for pro-oncogenic or tumor-suppressive functions of DAAs, that seemed to be dictated by the molecular background. Abstract Background and Aims: HCV eradication by direct-acting antiviral agents (DAAs) reduces de novo hepatocellular carcinoma (HCC) incidence in cirrhosis; however, contrasting evidence about beneficial or detrimental effects still exists in patients who have already developed HCC. Methods: we investigated whether sofosbuvir and daclatasvir modulate cell proliferation, invasion capability and gene expression (RNA-seq) in HCC-derived cell lines, hypothesizing possible off-target effects of these drugs. Results observed in HCC cell lines were validated in non-HCC cancer-derived cell lines and a preliminary series of human HCC tissues by qPCR and IHC. Results: DAAs can affect HCC cell proliferation and migration capability by either increasing or reducing them, showing transcriptomic changes consistent with some unexpected drug-associated effects. Off-target gene modulation, mainly affecting ribosomal genes, mitochondrial functions and histones, points to epigenetics and proliferation as relevant events, consistent with matched phenotypic changes. A preliminary validation of in vitro findings was performed in a restricted cohort of HCC patients previously treated with DAAs, with immunohistochemical correlations suggesting DAA-treated HCCs to be more aggressive in terms of migration and epidermal-to-mesenchymal transition. Conclusions: Our findings suggested the possible occurrence of off-target effects ultimately modulating cell proliferation and/or migration and potentially justified previous findings showing some instances of particularly aggressive HCC recurrence as well as reduced incidence of recurrence of HCC following treatment with DAAs.

Abstract
El Virus de la Hepatitis C (VHC) codifica la proteína Core. Core, además de ser la subunidad de la cápside, participa en diferentes mecanismos de patogénesis de la infección por VHC. Dado que el sistema de replicación in vitrodel VHC presenta limitaciones, el uso de vectores virales podría ser una herramienta útil para estudiar las propiedades de la proteína Core. Con el fin de validar el vector con el Virus del Bosque de Semliki (SFV) para el estudio de Core en células HepG2, se evaluó la expresión de la proteína verde fluorescente (GFP) y la proteína Core utilizando este vector viral. Las expresiones de GFP y Core se detectaron en células HepG2 transducidas con rSFV de 24 a 96 horas postransducción. La expresión de la proteína Core fue inferior a la expresión de GFP en las células HepG2. Teniendo en cuenta que la proteína Core del VHC puede regular la actividad del gen p53, se evaluó el nivel transcripcional de este gen. Se observó una disminución en el nivel de mARN de p53 en las células luego de la transducción, comparado con las células control. Aunque las células transducidas con rSFV-Core presentaron el menor nivel de mARN de p53,la diferencia no fue significativa comparada con las células transducidas con rSFV-GFP. Los resultados confirman que rSFV permite la expresión transitoria de proteínas heterólogas en líneas celulares de hepatoma humano. Se necesitan estudios adicionales para determinar si la expresión disminuida de Core puede deberse a degradación de la proteína viral.

Abstract
BACKGROUND & AIM An unexpected early increase in incidence, recurrence and clinical aggressiveness of hepatocellular carcinoma (HCC) has been reported (and refuted) in patients with HCV-related cirrhosis following direct-acting antiviral (DAA) treatment. To address this controversy, we performed a prospective multicenter study on consecutively enrolled cirrhotic patients, with or without a history of HCC, undergoing DAA therapy. PATIENTS AND METHODS A total of 1,161 HCC-free cirrhotics (group 1) and 124 cirrhotics who had received a curative treatment for an HCC (group 2) were enrolled. Clinical features, including presence of undefined/non-malignant liver nodules (UNMNs), were analyzed with respect to HCC incidence and recurrence. RESULTS During a median study time of 17 months in group 1 and 16 months in group 2, de novo HCC developed in 48 patients (yearly incidence 3.1/100 patient-years, 75% BCLC 0-A) and recurred in 40 (mean yearly incidence 29.9/100 patient-years, 83% BCLC 0-A). A peak of HCC instant incidence was observed at 4.2 months in group 1 patients with UNMNs, and at 7.7 months in group 2. By multivariable Cox regression models, UNMNs (hazard ratio [HR] 3.11; 95% CI 1.47-6.57: p = 0.003), ascites detected any time before enrolment (HR 3.04; 95% CI 1.23-7.51; p = 0.02), and alpha-fetoprotein log-value (HR 1.90; 95% CI 1.05-3.44; p = 0.03) were the variables independently associated with the incidence of de novo HCC, while history of alcohol abuse (HR 2.10; 95% CI 1.08-4.09; p = 0.03) and history of recurrence of HCC (HR 2.87; 95% CI 1.35-6.09; p = 0.006) were associated with HCC recurrence. CONCLUSION An early high incidence of both de novo HCC, in patients with UNMNs, and recurrent HCC was observed in DAA-treated patients; this was not accompanied by increased tumor aggressiveness. LAY SUMMARY This prospective study focuses on the risk of developing de novo or recurrent hepatocellular carcinoma (HCC) after direct-acting antiviral (DAA) treatment in patients with hepatitis C-related cirrhosis. We found that DAA treatment was associated with an early high HCC incidence in patients with undefined or non-malignant nodules, as well as in those with a history of complete response to HCC treatment. Whether this is related to the presence of clinically undetectable nests of cancer cells or to precancerous lesions that may progress to overt HCC upon DAA treatment remains unanswered. No evidence of increased clinical aggressiveness was reported in de novo or recurrent HCC.

Abstract
The recommendations set out the principles of diagnosis and treatment of hepatitis C virus (HCV) infections according to the most recent knowledge. The main goal of therapy for HCV infection is to eliminate the virus from the body, which consequently leads to arrest of progress or regression of changes in the liver. Current version of the recommendations prioritise pangenotypic regimens and provide guidelines in special populations of patients, such as children, cirrhotics, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) coinfected, those with renal failure, hepatic decompensation and non-responders to previous therapies.

Abstract
The feasibility and safety of microwave ablation in elderly hepatocellular carcinoma (HCC) patients remains unknown. The aim of this study was to evaluate the feasibility and safety of surgical microwave ablation for HCC in patients older than 80 years of age. This retrospective study enrolled consecutive 114 patients older than 80 years of age who underwent surgical microwave ablation for HCC between July 1994 and December 2017. We analyzed perioperative outcomes and long-term outcomes to clarify the prognostic factors. The 1-, 3-, 5-year overall survival and recurrence-free survival rates were 97.3%, 76.0%, 49.2% and 84.2%, 44.7%, and 32.5%, respectively. The overall major morbidity rates (Clavien–Dindo grade IIIA or above) were 2.6%. There were no cases of mortality. Multivariate analysis showed that hepatitis C virus antibody (HCV-Ab) positivity and the presence of multiple tumors were independent prognostic factors for long-term outcomes. The overall survival rate of patients with HCV-Ab negative and single tumor was better than that of other patients (p = 0.026). Surgical microwave ablation was feasible and safe for elderly patients with HCC. Elderly patients with HCV-Ab negative and single tumor would be expected to have better long-term outcomes after surgical microwave ablation.

Abstract
Chronic hepatitis C virus (HCV) infection increases the risk for several types of cancer, including hepatocellular carcinoma (HCC) and B-cell non-Hodgkin lymphoma, as primary and second primary malignancies. HCV-infected patients with cancer, particularly those undergoing anticancer therapy, are at risk for development of enhanced HCV replication, which can lead to hepatitis flare and progression of liver fibrosis or cirrhosis. Risk factors for HCV infection include injection drug use, blood transfusion, or solid organ transplantation before 1992, receipt of clotting factor concentrates before 1987, long-term hemodialysis, chronic liver disease, HIV positivity, and occupational exposure. Widely available direct-acting antivirals are highly effective against HCV and well tolerated. Identification of HCV-infected individuals is the essential first step in treatment and eradication of the infection. One-time screening is recommended for persons born from 1945 to 1965; screening is also recommended for persons with risk factors. Recently, a public health recommendation has been drafted to screen all adults age 18 to 79 years. Two oncology organizations recommend screening all patients with hematologic malignancies and hematopoietic cell transplant recipients, and a recently published multicenter prospective study supports universal HCV screening for all patients with cancer. HCV screening entails testing for anti-HCV antibodies in serum and, when results are positive, HCV RNA quantitation to confirm infection. Direct-acting antiviral therapy eradicates HCV in almost all cases. Virologic cure of HCV prevents chronic hepatitis and progression to liver fibrosis or cirrhosis. HCV eradication also decreases the risk of developing HCV-associated primary and second primary malignancies, and it may allow HCV-infected patients access to important cancer clinical trials. Patients with HCV-related cirrhosis require lifelong surveillance for HCC, even after viral eradication.

Abstract
BACKGROUND AND AIMS Direct-acting antivirals (DAAs) against hepatitis C virus (HCV) exert high anti-HCV activity and are expected to show anti-inflammatory effects associated with HCV elimination. Furthermore, hepatocellular carcinoma (HCC) is known to dedifferentiate from hypovascular tumors, such as dysplastic nodules or well-differentiated HCC, to hypervascular tumors. We therefore explored whether or not DAAs can suppress the growth and hypervascularization of hypovascular tumors. METHODS We enrolled 481 patients with HCV genotype 1 infection who were treated with Daclatasvir and Asunaprevir therapy. Of these, 29 patients had 33 hypovascular tumors, which were confirmed by contrast-enhanced MRI or CT before therapy. We prospectively analyzed the cumulative incidence of HCC, i.e. the growth or hypervascularization of hypovascular tumors, and compared the HCC development rates between patients with hypovascular tumors and those without any tumors. RESULTS The mean size of the hypovascular tumors was 11.3 mm. Twenty seven of 29 patients who achieved an SVR had 31 nodules, 19 of 31 nodules (61.3%) showed tumor growth or hypervascularization, and 12 (38.7%) nodules showed no change or improvement. The cumulative incidence rates of tumor growth or hypervascularization were 19.4% at 1 year, 36.0% at 2 years, 56.6% at 3 years, and 65.3% at 4 years. Among the patients who achieved a sustained virologic response, the cumulative HCC development rates of patients with hypovascular tumors was significantly higher than in those without any tumors. A Cox proportional hazard analysis showed that a history of HCC therapy, the presence of a hypovascular tumor, and AFP >4.6 ng/mL at the end of treatment were independent risk factors for HCC development. CONCLUSION Hypovascular tumors developed into HCC at a high rate despite the elimination of HCV by DAAs. As patients with hypovascular tumors were shown to have a high risk of HCC development, they should undergo strict HCC surveillance.

Abstract
The development of hepatocellular carcinoma (HCC) after a sustained virologic response (SVR) due to interferon (IFN) therapy for hepatitis C virus infection remains a serious problem. We herein report 2 cases of HCC that developed more than 20 years after SVR with IFN therapy for chronic hepatitis C. The patients were 89- and 72-year-old men with HCC that developed 24-25 years after an SVR with IFN therapy. These patients regularly underwent imaging examinations; therefore, the HCC was detected in the early stage, when it was still curable. Both cases suggest that long-term surveillance after an SVR is effective for the detection of HCC, and radical treatment is possible.

Abstract
BACKGROUND AND AIMS Chronic hepatitis C virus (HCV) infection is one of the major causal factors for hepatocellular carcinoma (HCC). The treatment options for HCC are limited for lack of a convenient animal model for study in HCV infection and liver pathogenesis. This study aimed to develop a patient-derived xenograft (PDX) tumor in mice by using a tumor from a patient with HCV-associated HCC and evaluating this model's therapeutic potential. APPROACH AND RESULTS After resection of the primary tumor from the patient liver, excess viable tumor was implanted into highly immunodeficient mice. A mouse xenograft tumor line was developed, and the tumor was successfully passaged for at least three rounds in immunodeficient mice. The patient's primary tumor and the mouse xenografts were histologically similar. Genetic profiling by short-tandem-repeat analysis verified that the HCC-PDX model was derived from the HCC clinical specimen. HCV RNA present in the patient liver specimen was undetectable after passage as xenograft tumors in mice. Human albumin, α1 -antitrypsin, glypican-3, α-smooth muscle actin, and collagen type 1A2 markers were detected in human original tumor tissues and xenograft tumors. Both the patient primary tumor and the xenograft tumors had a significantly higher level of receptor tyrosine kinase (c-Kit) mRNA. Treatment of HCC-PDX xenograft tumor-bearing mice with the c-Kit inhibitor imatinib significantly reduced tumor growth and phospho-Akt and cyclin D1 expression, as compared with untreated control tumors. CONCLUSIONS Our results demonstrated establishment of an HCV-associated HCC-PDX model as a powerful tool for evaluating candidate drugs. Information on molecular changes in cancer-specific gene expression facilitates efficient targeted therapies and treatment strategies.

Abstract
Noninvasive diagnostics for portal hypertension include imaging and functional tests, as well as blood-based biomarkers, and capture different features of the portal hypertensive syndrome. Definitive conclusions regarding their clinical utility require assessment of their diagnostic value in specific clinical settings (i.e., diagnosing a particular hemodynamic condition within a well-defined target population). Several noninvasive methods are predictive of clinically significant portal hypertension (CSPH; hepatic venous pressure gradient [HVPG] ≥ 10 mm Hg; the threshold for complications of portal hypertension); however, only a minority of them have been evaluated in compensated advanced chronic liver disease (i.e., the target population). Importantly, most methods correlate only weakly with HVPG at high values (i.e., in patients with CSPH). Nevertheless, selected methods show promise for diagnosing HVPG ≥ 16 mm Hg (the cut-off for increased risks of hepatic decompensation and mortality) and monitoring HVPG changes in response to nonselective beta-blockers or etiological treatments. Finally, we review established and potential future clinical applications of noninvasive methods.

Abstract
The introduction of direct-acting antiviral agents (DAA) has revolutionized management and care of patients with chronic hepatitis C virus (HCV) infection, leading to cure rates higher than 90% in patients with advanced liver disease as well. Viral eradication has been associated with longer survival, reduced mortality from both hepatic and extrahepatic causes, improvement in liver function, and reduced incidence of HCV-related extrahepatic diseases. While patients with mild fibrosis can safely be discharged after achievement of a sustained virological response, patients with advanced fibrosis and cirrhosis remain at risk of developing complications of liver disease, thus requiring regular and life-long surveillance. Major complications of cirrhosis that need to be monitored are hepatocellular carcinoma onset and development or progression of clinically significant portal hypertension.

Abstract
The long-term consequences of T cell responses’ impairment in chronic HCV infection are not entirely characterized, although they may be essential in the context of the clinical course of infection, re-infection, treatment-mediated viral clearance and vaccine design. Furthermore, it is unclear whether a complete reinvigoration of HCV-specific T cell response may be feasible. In most studies, attempting to reverse the effects of compromised immune response quality by specific blockades of negative immune regulators, a restoration of functional competence of HCV-specific T cells was shown. This implies that HCV-induced immune dysfunction may be reversible. The advent of highly successful, direct-acting antiviral treatment (DAA) for chronic HCV infection instigated investigation whether the treatment-driven elimination of viral antigens restores T cell function. Most of studies demonstrated that DAA treatment may result in at least partial restoration of T cell immune function. They also suggest that a complete restoration comparable to that seen after spontaneous viral clearance may not be attained, pointing out that long-term antigenic stimulation imprints an irreversible change on the T cell compartment. Understanding the mechanisms of HCV-induced immune dysfunction and barriers to immune restoration following viral clearance is of utmost importance to diminish the possible long-term consequences of chronic HCV infection.

Abstract
With liver-directed gene therapy, congenital haemophilia has the potential to progress from an incurable to a phenotypically curable condition. However, the proportion of haemophilia population likely to benefit from gene therapy remains to be established. Achieving a phenotypic curative goal is presently hampered by: 1) availability of effective treatments (e.g. extended half-life products, non-factor therapies) that address major unmet needs in haemophilia; 2) key differences between hope and reality that patients undergoing gene therapy face (e.g. unknown risks and long-term follow-up, durability of the therapeutic effect, possibility of re-administering the vector), 3) lack of expertise of health care professionals (HCP) in managing/monitoring unexpected side effects in patients, and 4) lack of expertise of HCP in advising payers on key issues for cost-effectiveness analyses of gene therapy (e.g., eligibility criteria, predictability of response, unknown risks, long-term complications). There is also uncertainty about the possibility to absorb the cost of the "one-time, one-dose cure" by payers that are used to different payment models. An active partnership between regulators, payers, patients and health care professionals is key to identify patient sub-populations that might benefit the most from gene therapy, and to align the interests of patients (needing effective disease correction and improved quality of life) and pharma companies (reluctant to lose the profitability of lifelong repeated treatments). Educational programs will provide the healthcare chain with information on the strategy that is expected to transform morbidity and mortality patterns and how it should be regarded as part of the future therapeutic options in haemophilia.

Abstract
Microvascular invasion (MVI) is an important predictor of metastatic tumour recurrence and is associated with adverse outcomes and poor prognosis in Hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients. The association between varying regimens of anti-viral drugs with the incidence of MVI in HBV-related HCC has been demonstrated, however, no meta-analysis of the available data has been conducted. Therefore, the current study sought to evaluate the association of preoperative antiviral therapy with incidence of microvascular invasion in HCC hepatitis virus patients. A systematic search of the literature was performed in MEDLINE/PubMed, Web of Science (WoS), and Scopus, up to January 2020. A random-effects model was used to estimate pooled odds ratios (ORs). Overall, six studies, with 4988 patients, met our inclusion criteria. The pooled OR of MVI in the patients who had preoperative antiviral therapy versus the patients who did not have antiviral therapy was; OR: 0.60, 95% Confidence Interval (CI): 0.49-0.73; I2 = 25%. In this study, a significant reduction in the OR of MVI was evident in patients who had anti-viral therapy.

Abstract
Abstract
Background
The impact of direct-acting antivirals (DAAs) remains a debate, whether they accelerate the recurrence rate of hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) after curative therapy. We evaluated the impact of direct-acting antiviral therapy on the rate of recurrence of HCV-related hepatocellular carcinoma following intervention in Egyptian patients.
Results
The results of the study represented an HCC recurrence rate of 38% in patients who received direct-acting antiviral therapy after HCC intervention versus 62% in those who did not receive antiviral therapy. In group I, according to the Barcelona Clinic of Liver Cancer (BCLC) staging, a higher recurrence rate was observed (57.9%) among patients who were classified as BCLC stage B.
Conclusions
HCC patients who did not receive direct-acting antiviral therapy after HCC intervention had a greater risk of HCC recurrence. DAAs did not increase the risk of HCC recurrence following HCC treatment; however, it did not abolish it. Close monitoring of patients after antiviral therapy is recommended.

Viral vectored hepatitis C virus vaccines generate pan-genotypic T cell responses to conserved subdominant epitopes. Vaccine 2020; 38:5036-5048.

Abstract
BACKGROUND Viral genetic variability presents a major challenge to the development of a prophylactic hepatitis C virus (HCV) vaccine. A promising HCV vaccine using chimpanzee adenoviral vectors (ChAd) encoding a genotype (gt) 1b non-structural protein (ChAd-Gt1b-NS) generated high magnitude T cell responses. However, these T cells showed reduced cross-recognition of dominant epitope variants and the vaccine has recently been shown to be ineffective at preventing chronic HCV. To address the challenge of viral diversity, we developed ChAd vaccines encoding HCV genomic sequences that are conserved between all major HCV genotypes and adjuvanted by truncated shark invariant chain (sIitr). METHODS Age-matched female mice were immunised intramuscularly with ChAd (108 infectious units) encoding gt-1 and -3 (ChAd-Gt1/3) or gt-1 to -6 (ChAd-Gt1-6) conserved segments spanning the HCV proteome, or gt-1b (ChAd-Gt1b-NS control), with immunogenicity assessed 14-days post-vaccination. RESULTS Conserved segment vaccines, ChAd-Gt1/3 and ChAd-Gt1-6, generated high-magnitude, broad, and functional CD4+ and CD8+ T cell responses. Compared to the ChAd-Gt1b-NS vaccine, these vaccines generated significantly greater responses against conserved non-gt-1 antigens, including conserved subdominant epitopes that were not targeted by ChAd-Gt1b-NS. Epitopes targeted by the conserved segment HCV vaccine induced T cells, displayed 96.6% mean sequence homology between all HCV subtypes (100% sequence homology for the majority of genotype-1, -2, -4 sequences and 94% sequence homology for gt-3, -6, -7, and -8) in contrast to 85.1% mean sequence homology for epitopes targeted by ChAd-Gt1b-NS induced T cells. The addition of truncated shark invariant chain (sIitr) increased the magnitude, breadth, and cross-reactivity of the T cell response. CONCLUSIONS We have demonstrated that genetically adjuvanted ChAd vectored HCV T cell vaccines encoding genetic sequences conserved between genotypes are immunogenic, activating T cells that target subdominant conserved HCV epitopes. These pre-clinical studies support the use of conserved segment HCV T cell vaccines in human clinical trials.

Cancer Manag Res 2020; 12:5323-5330. [PMID: 32753950 PMCID: PMC7345970 DOI: 10.2147/cmar.s254580] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Accepted: 06/15/2020] [Indexed: 12/12/2022] Open
Abstract
Background Hepatocellular carcinoma (HCC) caused by hepatitis C virus (HCV) infection has become less and less due to the use of direct-acting antiviral agents (DAAs). Although it may be common to assume that eradication of the virus should improve the survival of HCC patients, large-scale randomized clinical data to support the correlation between viral load and prognosis are still lacking in China. The aim of the study was to evaluate the efficacy of antiviral therapy for HCC patients with active HCV infection. Patients and Methods We retrospectively enrolled 80 HCC patients with active HCV infection. Active HCV infection was defined as positive for HCV antibody with detectable HCV RNA by polymerase chain reaction. Results Forty-four patients (55.0%) received interferon combined with ribavirin treatment and 23 patients achieved sustained virological response (SVR). The 1-year survival rate in patients who achieved SVR was the highest, followed by those with non-SVR after antiviral treatment, and those without antiviral therapy (1-year survival rate were 91.3%, 88.4%, and 73.1%, respectively, P = 0.012). In the univariate analysis, alcohol intake and alpha-fetoprotein >20 ng/mL were associated with lower overall survival (OS) (P = 0.025 and P = 0.044, respectively), while SVR after antiviral treatment was associated with longer OS (P = 0.016). In the multivariate analysis, only SVR after antiviral treatment was significantly associated with OS (P = 0.014). Conclusion Our results ensured that the elimination of HCV substantially improved OS in HCC patients with active HCV infection, and the prognosis of those patients without antiviral therapy was poor.

Abstract
The Drafting Committee for Hepatitis Management Guidelines established by the Japan Society of Hepatology (JSH) drafted the first version of the clinical practice guidelines for the management of hepatitis C virus (HCV) infection in 2012. Since then, we have been publishing updates as new drugs for hepatitis C become available and new indications for existing drugs are added. The new approval of sofosbuvir/velpatasvir prompted us to publish the seventh version of the guidelines in Japanese in March 2019. We also published the first English-language version of the JSH guidelines in 2013 and English versions of updates made to the Japanese-language guidelines in 2014 and 2016. In 2020, the committee has decided to publish a new English version, covering general information about treatment for hepatitis C, drugs used, recommended treatments for chronic hepatitis and cirrhosis, and special populations, such as patients who have renal impairment, are on dialysis, or have developed recurrence of hepatitis C after liver transplantation. Furthermore, the committee has released a separate publication covering the protective effect of antiviral therapy against hepatocarcinogenesis.

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.

Incidence of HCC in chronic hepatitis C patients with advanced hepatic fibrosis who achieved SVR following DAAs: A prospective study. J Viral Hepat 2020; 27:671-679. [PMID: 32050037 DOI: 10.1111/jvh.13276] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2019] [Revised: 11/03/2019] [Accepted: 01/13/2020] [Indexed: 12/11/2022]
Abstract
Liver cirrhosis is an important risk factor for hepatocellular carcinoma. The reported annual incidence of HCC is about 3%-8% in CHC cirrhotic patients. Based on the Cochrane systematic review, there was no clear evidence, on the long-term clinical effects of DAAs in patients achieving SVR, as regard liver cirrhosis-related HCC incidence. The aim of the study was to determine the incidence of HCC in chronic hepatitis C patients genotype IV with liver cirrhosis and advanced liver fibrosis after achieving SVR following DAA treatment in a prospective large cohort of HCV patients with long follow-up. This was a prospective observational cohort study including 2372 CHC patients with advanced liver fibrosis or cirrhosis receiving DAA therapy in outpatient clinics at the Egyptian Liver Research Institute and Hospital since January 2015. Liver fibrosis was assessed using transient elastography. Abdominal ultrasonography and AFP measurement were done at baseline and follow-up visits every 6 months, in addition to triphasic abdominal MSCT when needed. Patients were followed up after achieving SVR12 for at least 12 months. HCC developed in 109 cases during the follow-up period (mean 23.60 ± 8.25 months). Overall HCC incidence was 2.338/100 PY, 95% CI = 1.942-2.814. In patients with cirrhosis, the incidence of HCC was 2.917/100 PY, 95% CI = 2.407-3.535, while in patients with advanced liver fibrosis the incidence of HCC was 0.664/100 PY, 95% CI = 0.333-1.326. In conclusion, the incidence of HCC was reduced in chronic hepatitis C genotype 4 patients with liver cirrhosis (F4) and advanced hepatic fibrosis (F3) who achieved SVR following DAA therapy.

Risk Factors Contributing to the Occurrence and Recurrence of Hepatocellular Carcinoma in Hepatitis C Virus Patients Treated with Direct-Acting Antivirals. Biomedicines 2020.

Abstract
Although hepatitis C virus (HCV) RNA may be eliminated from blood circulation by direct-acting antivirals (DAA) therapy as assessed by real-time polymerase chain reaction (PCR), HCV RNA can still be present in liver tissue, and this is known as occult HCV. There has been a lot of controversy surrounding the recurrence of hepatocellular carcinoma (HCC) after DAA treatment of hepatic cells infected with chronic HCV. One of the main risk factors that leads to de novo HCC is the chronicity of HCV in hepatic cells. There are many studies regarding the progression of HCV-infected hepatic cells to HCC. However, there is a lack of research on the different molecular mechanisms that lead to the progression of chronic HCV infection to HCC, as well as on the effect of HCV on the alteration of DNA ploidy, which eventually leads to a recurrence of HCC after DAA treatment. In this review article, we will address some risk factors that could lead to the development/recurrence of HCC after treatment of HCV with DAA therapy, such as the role of liver cirrhosis, the alteration of DNA ploidy, the reactivation of hepatitis B virus (HBV), the role of cytokines and the alteration of the immune system, concomitant non- alcoholic fatty liver disease (NAFLD), obesity, alcohol consumption and also occult HCV infection/co-infection. Clinicians should be cautious considering that full eradication of hepatocarcinogenesis cannot be successfully accomplished by anti-HCV treatment alone.

Abstract
We aimed to evaluate the association of plasma biomarkers linked to inflammation (bacterial translocation, inflammatory response, and endothelial dysfunction), coagulopathy, and angiogenesis with the severity of liver cirrhosis (assessed by the Child-Pugh-Turcotte score, CTP) and Child-Pugh B cirrhosis (CTP 7–9) in patients with advanced hepatitis C virus (HCV)-related cirrhosis. We carried out a cross-sectional study in 97 patients with advanced HCV-related cirrhosis (32 HCV-monoinfected and 65 HIV/HCV-coinfected). Plasma biomarkers were measured by ProcartaPlex multiplex immunoassays. The outcome variable was the CTP score and the Child-Pugh B cirrhosis (CTP 7–9). HIV/HCV-coinfected patients and HCV-monoinfected patients with advanced HCV-related cirrhosis had near-equivalent values of plasma biomarkers. Higher values of plasma biomarkers linked to an inflammatory response (IP-10, IL-8, IL-6, and OPG), endothelial dysfunction (sVCAM-1 and sICAM-1), and coagulopathy (D-dimer) were related to higher CTP values. The most significant biomarkers to detect the presence of Child-Pugh B cirrhosis (CTP 7–9) were IP-10 (p-value= 0.008) and IL-6 (p-value=0.002). The AUC-ROC values of IP-10, IL-6, and both biomarkers combined (IP-10+IL-6) were 0.78, 0.88, and 0.96, respectively. In conclusion, HIV infection does not appear to have a significant impact on the analyzed plasma biomarkers in patients with advanced HCV-related cirrhosis. However, plasma biomarkers linked to inflammation (inflammatory response and endothelial dysfunction) were related to the severity of liver cirrhosis (CTP score), mainly IP-10 and IL-6, which discriminated patients with Child-Pugh B concerning Child-Pugh A.

Abstract
Purpose In interferon-free era, direct-acting antiviral agents (DAAs) have achieved high eradication rates with an excellent safety profile since revolutionized the management of hepatitis c virus (HCV) patients. Published papers have suggested a possible increased incidence of hepatocellular carcinoma (HCC) after successful DAAs treatment. Other papers have been published about the problem but without conclusive results. Because of this debate, we aim to evaluate the effects of antiviral therapy (Sofosbuvir plus Daclatasvir with or without Ribavirin) on the de novo occurrence of HCC in patients with liver cirrhosis (LC). Patients and Methods A prospective cohort study has included 350 patients who have visited our center for HCV treatment. Pretreatment history, examination, complete blood picture, liver function tests, kidney function tests, HA1C for diabetic patients, HCV PCR, HBsAg, alpha-fetoprotein (AFP), and abdominal ultrasound have been done, also Child-Pogh (CP) and Model for End-Stage Liver Disease (MELD) score before treatment. These investigations have been repeated for 3 months after the end of treatment. Abdominal ultrasound (US) has been done for 3 months after treatment and every 4 months for 2 years after the end of treatment to detect HCC occurrence. Results Patients age (58.11 ± 7.48), 55.4% of patients were males, 30.3% of patients were diabetic, 84.3% of them were treatment naïve and sustained virological response (SVR) occured in 94% of them. HCC occurrence after treatment was 6.7% in patients with SVR and 23.8% in patients with non-SVR (P value=0.016) during follow-up period. There is significant improvement of CP score. No significant changes in MELD score. Conclusion Treatment of HCV-related LC patients with sofosbuvir and daclatasvir with or without ribavirin for 3 or 6 months showed high SVR and significant improvement in CP score, but still at risk of HCC even if treated and should be followed up regularly according to screening programs with special meticulous attention to those with non-SVR.

Laursen TL, Sandahl TD, Kazankov K, George J, Grønbæk H. Liver-related effects of chronic hepatitis C antiviral treatment. World J Gastroenterol 2020; 26:2931-2947. [PMID: 32587440 PMCID: PMC7304101 DOI: 10.3748/wjg.v26.i22.2931] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 03/26/2020] [Accepted: 05/29/2020] [Indexed: 02/06/2023] Open
Abstract
More than five years ago, the treatment of hepatitis C virus infection was revolutionized with the introduction of all-oral direct-acting antiviral (DAA) drugs. They proved highly efficient in curing patients with chronic hepatitis C (CHC), including patients with cirrhosis. The new DAA treatments were alleged to induce significant improvements in clinical outcome and prognosis, but the exact cause of the expected benefit was unclear. Further, little was known about how the underlying liver disease would be affected during and after viral clearance. In this review, we describe and discuss the liver-related effects of the new treatments in regards to both pathophysiological aspects, such as macrophage activation, and the time-dependent effects of therapy, with specific emphasis on inflammation, structural liver changes, and liver function, as these factors are all related to morbidity and mortality in CHC patients. It seems clear that antiviral therapy, especially the achievement of a sustained virologic response has several beneficial effects on liver-related parameters in CHC patients with advanced liver fibrosis or cirrhosis. There seems to be a time-dependent effect of DAA therapy with viral clearance and the resolution of liver inflammation followed by more discrete changes in structural liver lesions. These improvements lead to favorable effects on liver function, followed by an improvement in cognitive dysfunction and portal hypertension. Overall, the data provide knowledge on the several beneficial effects of DAA therapy on liver-related parameters in CHC patients suggesting short- and long-term improvements in the underlying disease with the promise of an improved long-term prognosis.

Long-Term Follow-Up of the First in Human Intravascular Delivery of AAV for Gene Transfer: AAV2-hFIX16 for Severe Hemophilia B. Mol Ther 2020; 28:2073-2082. [PMID: 32559433 DOI: 10.1016/j.ymthe.2020.06.001] [Citation(s) in RCA: 119] [Impact Index Per Article: 29.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Revised: 05/26/2020] [Accepted: 06/03/2020] [Indexed: 12/26/2022] Open
Abstract
Adeno-associated virus (AAV) vectors are a leading platform for gene-based therapies for both monogenic and complex acquired disorders. The success of AAV gene transfer highlights the need to answer outstanding clinical questions of safety, durability, and the nature of the human immune response to AAV vectors. Here, we present longitudinal follow-up data of subjects who participated in the first trial of a systemically delivered AAV vector. Adult males (n = 7) with severe hemophilia B received an AAV2 vector at doses ranging from 8 × 1010 to 2 × 1012 vg/kg to target hepatocyte-specific expression of coagulation factor IX; a subset (n = 4) was followed for 12-15 years post-vector administration. No major safety concerns were observed. There was no evidence of sustained hepatic toxicity or development of hepatocellular carcinoma as assessed by liver transaminase values, serum α-fetoprotein, and liver ultrasound. Subjects demonstrated persistent, increased AAV neutralizing antibodies (NAbs) to the infused AAV serotype 2 (AAV2) as well as all other AAV serotypes tested (AAV5 and AAV8) for the duration of follow-up. These data represent the longest available longitudinal follow-up data of subjects who received intravascular AAV and support the preliminary safety of intravascular AAV administration at the doses tested in adults. Data demonstrate, for the first time, the persistence of high-titer, multi-serotype cross-reactive AAV NAbs for up to 15 years post- AAV vector administration. Our observations are broadly applicable to the development of AAV-mediated gene therapy.

Direct-Acting Antiviral Agents Reduce the Risk of Malignant Transformation of Hepatobiliary Phase-Hypointense Nodule without Arterial Phase Hyperenhancement to Hepatocellular Carcinoma on Gd-EOB-DPTA-Enhanced Imaging in the Hepatitis C Virus-Infected Liver. Liver Cancer 2020; 9:261-274. [PMID: 32647630 PMCID: PMC7325122 DOI: 10.1159/000504889] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Accepted: 10/26/2019] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND AND AIMS Hepatobiliary phase-hypointense nodules without arterial phase hyperenhancement (HHNs without APHE) on gadolinium-ethoxybenzyl-diethylenetriamine-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI) are considered to be dysplastic nodules or early hepatocellular carcinoma (HCC) and have high risk of undergoing malignant transformation and progression to hypervascular HCC. The aim of this study was to evaluate the clinical outcome of HHNs without APHE diagnosed by Gd-EOB-DTPA-enhanced MRI before the eradication of HCV by direct-acting antiviral agents (DAAs). METHODS We retrospectively investigated 221 consecutive patients with HCV infection who were treated with DAAs. Thirty patients with 65 HHNs without APHE were enrolled in a sustained virologic response (SVR) cohort and 22 with 43 HHNs without APHE who did not receive DAAs or had failed HCV eradication therapy were enrolled in a non-SVR cohort. Fifty-seven percent of patients in the SVR group and 64% of those in the non-SVR group had a history of HCC. The primary endpoint of this study was the development of hypervascular HCC from HHNs without APHE detected on imaging. The cumulative incidence and relative risk of progression to hypervascular HCC in relation to clinical characteristics were compared between the two cohorts. RESULTS The 2-year cumulative incidence of progression to hypervascular HCC was 8.5 and 21.9% in the SVR and non-SVR cohorts, respectively. There was a significant reduction in progression of HHNs without APHE to HCC after the eradication of HCV (p = 0.022, log-rank test). Multivariate Cox regression analysis identified hyperintensity on T2-weighted images (relative risk 14.699, p < 0.001) and achieving SVR (relative risk 0.290, p = 0.043) as independent factors associated with the risk of HCC. During follow-up, 6 (9.2%) of the HHNs without APHE in the SVR cohort became undetectable on hepatocyte-phase images. CONCLUSIONS Eradication of HCV by DAAs could reduce the hypervascularization rate of HHNs without APHE, and some of these nodules disappeared.

Abstract
The cure of chronic hepatitis C infection has a major impact on the morbidity and mortality of infected patients. It is now clear that sustained virologic response improves overall survival and significantly reduces the risk of liver failure, fibrosis progression, need of liver transplantation, and incidence of hepatocellular carcinoma. Moreover, hepatitis C eradication improves a broad range of extrahepatic manifestations, such as dermatologic, neoplastic, cardiovascular, and endocrine, and improves quality of life.
