Abstract
BACKGROUND There have been increasing reports of HBV reactivation in HBV and HCV coinfected patients with direct-acting antiviral (DAA) treatment. The potential risk of HBV reactivation in patients undergoing haemodialysis has also been noted. There is a lack of data pertaining to the reactivation risk during DAA treatment in those coinfected patients with end-stage renal disease who are undergoing haemodialysis. METHODS HBV-HCV-coinfected patients were screened from 178 persons at two blood purification centres in China and received sofosbuvir (200 mg) combined with daclatasvir (60 mg) daily. The risk and pattern of HBV reactivation during DAA treatment was retrospectively analysed. RESULTS HBV reactivation occurred in 45.5% (5/11) of the HBV-HCV-coinfected patients undergoing haemodialysis during DAA treatment, which was much higher than the reported rates in the general population of coinfected patients. Five patients with HBV reactivation were all positive for hepatitis B surface antigen (HBsAg) before DAA treatment. Three patients (27.3%) had mild hepatitis flares due to HBV reactivation, but no patients had severe hepatitis or hepatic failure. Compared with the four patients who were HBsAg- at the baseline, the risk of HBV reactivation in HBsAg+ patients was greater (71.4% versus 0; χ2=5.238; P=0.061), although the difference was not statistically significant. CONCLUSIONS A significant proportion of HBV-HCV-coinfected patients undergoing haemodialysis developed HBV reactivation after DAA therapy. The risk of HBV reactivation was greater in HBsAg+ patients than in those patients who were HBsAg- but anti-HBc+ or HBV DNA+.

J Hepatocell Carcinoma 2020; 7:45-76. [PMID: 32346535 PMCID: PMC7167284 DOI: 10.2147/jhc.s221187] [Citation(s) in RCA: 42] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2019] [Accepted: 03/06/2020] [Indexed: 12/12/2022] Open
Abstract
Hepatitis C virus (HCV) infection is the major risk factor for liver cirrhosis and hepatocellular carcinoma (HCC). The mechanisms of HCC initiation, growth, and metastasis appear to be highly complex due to the decade-long interactions between the virus, immune system, and overlapping bystander effects of host metabolic liver disease. The lack of a readily accessible animal model system for HCV is a significant obstacle to understand the mechanisms of viral carcinogenesis. Traditionally, the primary prevention strategy of HCC has been to eliminate infection by antiviral therapy. The success of virus elimination by antiviral treatment is determined by the SVR when the HCV is no longer detectable in serum. Interferon-alpha (IFN-α) and its analogs, pegylated IFN-α (PEG-IFN-α) alone with ribavirin (RBV), have been the primary antiviral treatment of HCV for many years with a low cure rate. The cloning and sequencing of HCV have allowed the development of cell culture models, which accelerated antiviral drug discovery. It resulted in the selection of highly effective direct-acting antiviral (DAA)-based combination therapy that now offers incredible success in curing HCV infection in more than 95% of all patients, including those with cirrhosis. However, several emerging recent publications claim that patients who have liver cirrhosis at the time of DAAs treatment face the risk of HCC occurrence and recurrence after viral cure. This remains a substantial challenge while addressing the long-term benefit of antiviral medicine. The host-related mechanisms that drive the risk of HCC in the absence of the virus are unknown. This review describes the multifaceted mechanisms that create a tumorigenic environment during chronic HCV infection. In addition to the potential oncogenic programming that drives HCC after viral clearance by DAAs, the current status of a biomarker development for early prediction of cirrhosis regression and HCC detection post viral treatment is discussed. Since DAAs treatment does not provide full protection against reinfection or viral transmission to other individuals, the recent studies for a vaccine development are also reviewed.

Abstract
Background Hepatitis C virus (HCV) coinfection among people with human immunodeficiency virus (HIV) might perturb immune function and HIV persistence. We aimed to evaluate the impact of HCV clearance with direct-acting antivirals (DAAs) on immune activation and HIV persistence in HIV/HCV-coinfected individuals on antiretroviral therapy (ART). Methods In a prospective observational study, ART-treated participants with HIV/HCV coinfection received sofosbuvir/daclatasvir ± ribavirin (n = 19). Blood samples were collected before DAA therapy, at the end of treatment, and 12 months after DAA termination (12MPT). T- and natural killer (NK)-cell phenotype, soluble plasma factors, cell-associated (CA)-HIV deoxyribonucleic acid (DNA) forms (total, integrated, 2LTR), CA-unspliced (US) and multiple-spliced ribonucleic acid (RNA), and plasma HIV RNA were evaluated. Results Hepatitis C virus clearance was associated with (1) a downmodulation of activation and exhaustion markers in CD4+, CD8+ T, and NK cells together with (2) decreased plasma levels of Interferon gamma-induced protein 10 (IP10), interleukin-8 (IL-8), soluble (s)CD163 and soluble intercellular adhesion molecule (sICAM). Cell-associated US HIV RNA was significantly higher at 12MPT compared to baseline, with no change in HIV DNA or plasma RNA. Conclusions Elimination of HCV in HIV/HCV-coinfected individuals alters immune function and the transcriptional activity of latently infected cells. This report provides insights into the effects of HCV coinfection in HIV persistence and regards coinfected subjects as a population in which HIV remission might prove to be more challenging.

Human genetics of HCV infection phenotypes in the era of direct-acting antivirals. Hum Genet 2020; 139:855-863.

Abstract
The recent introduction of direct-acting antivirals (DAAs) has revolutionized hepatitis C virus (HCV) therapy by improving virus eradication rates to over 90% in most patient groups. However, the impact of DAAs on global disease burden is currently limited, and a large number of chronically infected individuals remain at risk of developing liver complications, such as liver cirrhosis and hepatocellular carcinoma (HCC). The identification of patients at risk of liver complications and a greater understanding of the biological mechanisms involved in HCV disease progression might improve disease control. Recent genome-wide association and exome sequencing studies have identified several host genetic variants influencing the progression of liver fibrosis and the development of HCC associated with HCV infection and are reviewed here. Interestingly, some of the genetic variants associated with those HCV-associated liver complications were also associated with the clinical course of non-viral chronic hepatitis. Future challenges include the incorporation of this genetic information into clinical risk models for personalized disease management and the study of emerging phenotypes such as liver fibrosis regression and HCC development after HCV eradication.

Abstract
Background Sparse population-based data are available on the prevalence and etiology of chronic liver disease (CLD) in Italy. The study aims to assess the role of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in CLD according to age, gender and ethnicity. Methods Clinically diagnosed CLD in the general population aged 20–59 years in the Veneto Region (North-Eastern Italy) were identified through the Adjusted Clinical Groups System, by record linkage of the archive of subjects enrolled in the Regional Health System with Hospital Discharge Records, Emergency Room visits, Chronic disease registry for copayment exemptions, and the Home care database. Age-standardized prevalence rates (PR) were computed in Italians and immigrants, based on country of citizenship. Results Overall 22,934 subjects affected by CLD in 2016 were retrieved, 21% related to HBV and 43% to HCV infection. The prevalence of HCV-related CLD was higher in males, peaking at 50–54 years (males = 11/1000; females = 4/1000). The PR of HBV-related CLD was almost negligible in the Italian population (1/1000), and higher among immigrants, especially from East Asia (males = 17/1000; females = 11/1000) and Sub-Saharan Africa (males = 13/1000; females = 10/1000). Conclusion Specific population sub-groups identified by age, gender, and ethnicity, were demonstrated to be at increased risk, and these trends are in line with global epidemiological patterns of viral hepatitis.

Abstract
BACKGROUND The sustained virological response (SVR) rate for the 12-week sofosbuvir (SOF)/ledipasvir (LVD) treatment of adolescent genotype-4 patients is high. The aim of this study is to evaluate 8 versus 12-week treatment efficacy and safety in adolescent genotype-4 patients. PATIENTS AND METHODS In total, 157 chronic hepatitis C-infected adolescent patients (mean age 14±2 years, 62% males) were included in this study. All patients received a morning dose of SOF (400 mg)/LVD (90 mg) as a single tablet for 8 and 12 weeks. Laboratory and biochemical monitoring were performed at weeks 4 and 8, end of treatment (8/12) and 12 weeks after the end of treatment (SVR12). RESULTS In total, SVR12 was 98% [95% confidence interval (CI): 96-100] for all treated patients. For patients treated for 12 weeks, SVR12 was 97.6% (95% CI: 96-101) (82/84 patients), and 98.6% (95% CI: 93-101) (72/73) patients for those treated for 8 weeks. For both regimens, no serious adverse effects, treatment discontinuation or cases of death were detected. The main adverse effects for the 8-week patient group were fatigue (2.8%), headache (1.4%), nausea (1.4%) and epigastric tenderness (1.4%). For the 12-week-treated group, adverse events were epigastric tenderness (1.2%), nausea (1.2%), diarrhoea (2.4%) and rash (2.4%). Three patients were lost to follow-up: two were in the 12-week treatment group and one was in the 8-week group. All of them reached end of treatment but were lost before SVR12. No relapsers were observed in either group. CONCLUSION Eight weeks of treatment of SOF/LVD combination is equally effective and safe as 12 weeks in adolescent genotype-4 patients.

Abstract
BACKGROUND AND AIMS The World Health Organization recently called for the elimination of hepatitis C virus (HCV) and has identified people who inject drugs (PWID) as a key target population. Clinical trials analyzing currently available all-oral regimens have demonstrated a high degree of efficacy in this population, with a relatively low reinfection rate. There is an urgent need to confirm these data in a harm reduction and active consumption setting. The primary aim of this study was to evaluate the HCV reinfection rate in people with recent drug use followed at low-threshold mobile harm reduction units. METHOD We included people with recent drug use (smoked or injected heroin/cocaine in the previous 6 months) who received HCV treatment and were attended at two low-threshold mobile harm reduction units over 19 months. Sustained virologic response was assessed 12 weeks after therapy (SVR12). The incidence density of HCV reinfection was defined as the number of reinfections per 100-person years (PY) using person-time of observation and was stratified by drug consumption at initiation of HCV treatment. Cox proportional hazard regression analysis was used to assess factors associated with reinfection. RESULTS During the study period, 160 people who used drugs in the past 6 months completed HCV therapy. 122 (73.9%) and 88 (53.3%) reported injecting drug use in the 6 months and 30 days prior to HCV treatment, respectively. The overall SVR12 was 68% in the ITT analysis (reinfection = failure) and 90.7% in the modified intent-to-treat analysis (considering reinfections as response and removing people who were missing SVR data). The cohort at-risk for reinfection (n = 121) included 47 (39.2%) people who initiated HCV treatment with recently reported abstinence. Reinfection was identified in 10 persons (8.3%), and the median time to reinfection was 7.2 (IQR 4.2-18) months. Total follow-up time at-risk was 101.1-PY (median 0.6 years, IQR 0.3-1.3). The overall incidence of reinfection was 9.8 per 100-PY (95% CI 4.7,18.2). The incidence of reinfection was higher amongst those who had injected drugs in the previous 6 months (16.7 [95%CI 8.0; 30.7] per 100-PY) and in the previous 30 days (18.9 [95% CI 8.1; 37.2] per 100-PY). In the adjusted analysis, only injecting drugs use in the month prior to initiation of HCV therapy was associated with reinfection (aHR 8.7, 95%CI 1.0; 73.6; p 0.04). CONCLUSION High efficacy of HCV treatment, was found in people with recent drug use attended and followed at low-threshold mobile harm reduction units. The high rate of early HCV reinfections in this setting should promote surveillance for reinfection at 7-month intervals after ending the treatment or earlier.

Abstract
Elimination of the three blood-borne viruses-human immunodeficiency virus (HIV), hepatitis B (HBV) and hepatitis C (HCV)-as public health issues may be plausible in the near future. Spectacular advances have been made with the introduction of highly effective antiviral agents into clinical practice, and prevention strategies are available for all three infections. Effective disease control, laid out by WHO global strategies, is currently feasible for all three viruses. However, for worldwide elimination of these viruses, effective vaccines are required that are currently only available for HBV. In this review differences and parallels among HIV, HCV and HBV will be discussed with a focus on virologic and therapeutic issues, and prospects for the future of HBV will be presented.

Abstract
BACKGROUND Treatment with direct-acting antivirals (DAA) eradicates hepatitis C virus (HCV) from most chronic carriers. Information on regression of liver fibrosis and the influence of HIV is scarce in cured patients. METHODS All consecutive HCV-infected individuals treated with DAA at our institution were examined. Hepatic elastography was performed at baseline and at the time of SVR12. Liver fibrosis regression was defined as a shift from advanced fibrosis (Metavir F3-F4) to null-mild fibrosis (F0-F2) and/or a reduction greater than 30% kPa. AST to platelet ratio index (APRI) and fibrosis 4 (FIB-4) scores were calculated in parallel. RESULTS A total of 260 patients were treated with DAA. All but 14 achieved SVR12 and represented the study population. HIV confection was present in 42%. At baseline, 57.2% had advanced liver fibrosis with a median of 11 kPa, FIB-4 of 2.4, and APRI of 0.95. At the time of SVR12, a median reduction of 2.1 kPa (P < 0.001) was recognized using elastography. A significant fibrosis regression was seen in 40%, being more frequent in patients with baseline advanced fibrosis than in those with null-mild fibrosis (52.3 vs. 22.5%; P < 0.001). Even so, 41.2% of patients with baseline F3-F4 kept within cirrhotic scores. In multivariable analysis, only baseline stiffness was significantly associated with the extent of liver fibrosis regression. CONCLUSION HCV cure with DAA is associated with regression of liver fibrosis in most patients treated with DAA, as measured using elastography, FIB-4 and APRI. This benefit is more pronounced in patients with baseline advanced fibrosis and cirrhosis. The dynamics of liver fibrosis regression are not influenced by HIV coinfection.
