Combined Liver Stiffness and Α-fetoprotein Further beyond the Sustained Virologic Response Visit as Predictors of Long-Term Liver-Related Events in Patients with Chronic Hepatitis C. Can J Gastroenterol Hepatol 2022; 2022:5201443. [PMID: 35837486 PMCID: PMC9273470 DOI: 10.1155/2022/5201443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 05/26/2022] [Accepted: 06/16/2022] [Indexed: 11/17/2022] Open
Abstract
AIMS Long-term risk stratification using combined liver stiffness (LS) and clinically relevant blood tests acquired at the baseline further beyond the sustained virologic response (SVR) visit for chronic hepatitis C (CHC) has not been thoroughly investigated. This study retrospectively investigated the prognostics of liver-related events (LREs) further beyond the SVR visit. METHODS Cox regression and random forest models identified the key factors, including longitudinal LS and noninvasive test results, that could predict LREs, including hepatocellular carcinoma, during prespecified follow-ups from 2010 to 2021. Kaplan-Meier survival analysis estimated the significance of between-group risk stratification. RESULTS Of the entire eligible cohort (n = 520) of CHC patients with SVR to antiviral therapy, 28 (5.4%) patients developed post-SVR LREs over a median follow-up period of 6.1 years (interquartile range = 3.5-8.7). The multivariate Cox regression analysis identified two significant predictors of LREs after the year 3 post-SVR (Y3PSVR) baseline (LRE, n = 15 of 28, 53.6%, median follow-up = 4.1 [1.6-6.4] years after Y3PSVR): LS at Y3PSVR (adjusted hazard ratio [aHR] = 3.980, 95% confidence interval [CI] = 2.085-7.597, P < 0.001), and α-fetoprotein (AFP) at Y3PSVR (aHR = 1.017, 95% CI = 1.001-1.034, P=0.034). LS ≥1.45 m/s and AFP ≥3.00 ng/mL for Y3PSVR yielded positive likelihood ratios of 4.24 and 2.62, respectively. Kaplan-Meier analysis revealed that among the stratified subgroups, the subgroup with concurrent LS ≥1.45 m/s and AFP ≥3.00 ng/mL at Y3PSVR exhibited the highest risk of LREs after Y3PSVR (log-rank P < 0.001). CONCLUSION We recommend the combined use of concurrent LS and AFP in future prediction models for LREs in CHC. Patients with concurrently high LS and AFP values further beyond the SVR visit may require a recall policy involving intense surveillance.

Cost-Effectiveness Analysis of Pan-Genotypic Sofosbuvir-Based Regimens for Treatment of Chronic Hepatitis C Genotype 1 Infection in China. Front Public Health 2021; 9:779215. [PMID: 34957030 PMCID: PMC8695807 DOI: 10.3389/fpubh.2021.779215] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Accepted: 11/18/2021] [Indexed: 11/21/2022] Open
Abstract
Background: Hepatitis C virus (HCV) genotype 1 is the most prevalent HCV infection in China. Sofosbuvir-based direct antiviral agent (DAA) regimens are the current mainstays of treatment. Sofosbuvir/velpatasvir (SOF/VEL) and sofosbuvir/ledipasvir (SOF/LDV) regimens became reimbursable in China in 2020. Thus, this study aimed to identify the optimal SOF-based regimen and to inform efficient use of healthcare resources by optimizing DAA use in treating HCV genotype 1. Methods and Models: A modeling-based cost-utility analysis was conducted from the payer's perspective targeting adult Chinese patients with chronic HCV genotype 1 infection. Direct medical costs and health utilities were inputted into a Markov model to simulate lifetime experiences of chronically infected HCV patients after receiving SOF/LDV, SOF/VEL or the traditional strategy of pegylated interferon (pegIFN) + ribavirin (RBV). Discounted lifetime cost and quality adjusted life years (QALYs) were computed and compared to generate the incremental cost utility ratio (ICUR). An ICUR below the threshold of 31,500 $/QALY suggests cost-effectiveness. Deterministic and probabilistic sensitivity analyses were performed to examine the robustness of model findings. Results: Both SOF/LDV and SOF/VEL regimens were dominant to the pegIFN + RBV regimen by creating more QALYs and incurring less cost. SOF/LDV produced 0.542 more QALYs but cost $10,390 less than pegIFN + RBV. Relative to SOF/LDV, SOF/VEL had an ICUR of 168,239 $/QALY which did not meet the cost-effectiveness standard. Therefore SOF/LDV was the optimal strategy. These findings were robust to linear and random variations of model parameters. However, reducing the SOF/VEL price by 40% would make this regimen the most cost-effective option. Conclusions: SOF/LDV was found to be the most cost-effective treatment, and SOF/VEL was also economically dominant to pegIFN + RBV. These findings indicated that replacing pegIFN + RBV with DAA regimens could be a promising strategy.

Genetic variants associated with serum alanine aminotransferase levels among patients with hepatitis C virus infection: A genome-wide association study. J Viral Hepat 2021; 28:1265-1273. [PMID: 34003538 DOI: 10.1111/jvh.13550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 03/12/2021] [Accepted: 04/17/2021] [Indexed: 12/09/2022]
Abstract
Information on genetic variants associated with elevated serum alanine aminotransferase (ALT) levels remains limited. A genome-wide association study was performed to identify single-nucleotide polymorphisms (SNPs) associated with ALT levels. The ALT-associated SNP was further evaluated for hepatocellular carcinoma (HCC) risk. A cohort of 892 anti-HCV seropositive patients was used for genome-wide SNP array to examine the associations with baseline ALT levels. SNPs <10-5 were further tested for associations with serial ALT levels then validated in 486 anti-HCV seropositives. Multinomial logistic regressions were used to estimate odds ratios (ORs) and 95% confidence intervals of SNPs associated with ALT. The SNP was evaluated for HCC risk by using Cox's proportional hazards models. After quality control, 803 participants with 564,464 SNPs were included in the analysis. Of these, 12 SNPs were associated with ALT (p < 10-5 ). Among the participants, 158 (19.7%) had ALT persistently ≤15 U/L, 327 (40.7%) ever >15 U/L but never >45 U/L, and 318 (39.6%) ever >45 U/L during follow-up. The rs568800 was associated with serial ALT levels, and this was replicated in the external population significantly (p < .05). The A allele (vs C) of rs568800 was associated with ALT >15 U/L but ≤45 U/L and ALT >45 U/L, with the adjusted ORs of 1.41 (1.11-1.78) and 1.86 (1.34-2.60), respectively. The adjusted HRs for HCC were 2.09 (0.90-4.89) for AC and 2.64 (1.13-6.17) for AA (CC as a reference). In conclusion, the rs568800 was associated with serum ALT levels and HCC risk. Clinical utility should be evaluated among patients who have received antivirals.

Abstract
OBJECTIVES The impact of viral eradication on hepatic angiogenesis is unknown. This study aimed to analyze the correlations of liver angiogenesis with liver fibrosis progression or regression in chronic hepatitis C (CHC) after viral eradication. METHODS From 2003 to 2020, a cohort of 130 eligible participants underwent paired percutaneous liver biopsies (median = 48 months apart; range = 46-62) at the treatment baseline and after sustained virological response to CHC treatment at the tertiary referral center. The collagen proportionate area (CPA) of liver tissue sections was determined using picrosirius red staining through digital image analysis. CD34 and α-smooth muscle actin (α-SMA) phenotypically quantitated liver angiogenesis and myofibroblasts, respectively, through immunohistochemistry staining, to correlate the total, portal, and extraportal liver angiogenesis with fibrogenesis. RESULTS Paired histology manifested significant regressions in fibrosis stages, and necroinflammatory grades (both P < 0.001). The median of changes in CPAs (follow-up minus baseline) was -6.12% (interquartile range = -12.35 to -2.05%). The median of CPA changes per year was -1.38%/year (interquartile range = -2.98 to -0.51%/year). The significance of declines in total CD34 [coefficient (95% confidence interval), 5.577 (3.286-7.868); P < 0.001] outweighed α-SMA declines, when explaining (R2 = 0.522; adjusted R2 = 0.502) the CPA declines through multiple regression analysis adjusting for other histological variables. CONCLUSION Through viral eradication in CHC, the downregulated liver angiogenesis significantly explains the CPA regression.

Abstract
IFNL3/IFNL4 polymorphisms are inversely associated with the risk of chronic hepatitis C virus (HCV) infection and cirrhosis, two major risk factors for developing hepatocellular carcinoma (HCC). To further explore these inverse associations and their molecular underpinnings, we analyzed IFNL3/IFNL4 polymorphisms represented by the IFNL4 genotype (presence of rs368234815-dG or rs12979860-T alleles) in HCV patients: 2969 from Japan and 2931 from Taiwan. IFNL4 genotype was associated with an increased risk of HCV-related HCC (OR=1.28, 95%CI=1.07-1.52, P=0.0058) in the general population of Japanese patients, but not in Taiwanese patients who achieved treatment-induced viral clearance. IFNL4 genotype was also associated with a decreased risk of cirrhosis (OR=0.66, 95%CI=0.46-0.93, P=0.018, in Taiwanese patients). We then engineered HepG2 cells to inducibly express IFN-λ4 in the presence or absence of interferon lambda receptor 1 (IFNLR1). Induction of IFN-λ4 resulted in its intracellular accumulation, mainly in lysosomes and late endosomes, and increased ER stress, leading to apoptosis and reduced proliferation. We identified the very-low-density lipoprotein receptor (VLDLR), which facilitates HCV entry into hepatocytes, as a transcript induced by IFN-λ4 but not IFN-λ3. Our results suggest that the molecular mechanisms underlying the anti-cirrhotic but pro-HCV associations observed for IFNL3/IFNL4 polymorphisms are, at least in part, contributed by intracellular accumulation of IFN-λ4 causing ER stress in hepatic cells.

Abstract
Seven viruses including the Epstein-Barr virus (EBV), hepatitis B virus (HBV), hepatitis C virus (HCV), Kaposi's sarcoma herpes virus (KSHV), human immunodeficiency virus, type-1 (HIV-1), human T cell lymphotrophic virus, type-1 (HTLV-1), and human papillomavirus (HPV) have been classified as Group 1 human carcinogens by the International Agency for Research on Cancer (IARC). The conclusions are based on the findings of epidemiological and mechanistic studies. EBV, HPV, HTLV-1, and KSHV are direct carcinogens; HBV and HCV are indirect carcinogens through chronic inflammation; and HIV-1 is an indirect carcinogen through immune suppression. Some viruses may cause more than one cancer, while some cancers may be caused by more than one virus. However, only a proportion of persons infected by these oncogenic viruses will develop specific cancers. A series of studies have been carried out to assess the viral, host, and environmental cofactors of EBV-associated nasopharyngeal carcinoma, HBV/HCV-associated hepatocellular carcinoma, and HPV-associated cervical carcinoma. Persistent infection, high viral load, and viral genotype are important risk predictors of these virus-caused cancers. Risk calculators incorporating host and viral risk predictors have been developed for the prediction of long-term risk of hepatocellular carcinoma, nasopharyngeal carcinoma and cervical cancer. These risk calculators are useful for the triage and clinical management of infected patients. Both clinical trials and national programs of immunization, antiviral therapy and screening have demonstrated a significant reduction in the incidence of cancers caused by HBV, HCV, and HPV. Future research on gene-gene and gene-environment interactions of oncogenic viruses and the human host using large-scale longitudinal studies with serial measurements of biosignatures are in urgent need.

Abstract
Hepatitis C virus (HCV) infection is the leading cause of chronic liver diseases worldwide. Monitoring its epidemiology, diagnosis, and treatment patterns are important for the management of patients with chronic HCV infection from both individual and public health perspectives. The MOSAIC study was an observational study conducted in 20 countries, including Taiwan; its primary objective was to describe epidemiology and treatment initiation patterns in patients seeking HCV care. Of the 111 chronic HCV patients enrolled from Taiwan, 58 (52.3%) had not previously received treatment. HCV genotype 1 was reported in 58 (52.3%) patients, of whom the majority (n = 47; 81.0%) were identified as having subtype 1b. Sixty-two (55.9%) patients had HCV RNA level > 800 000 IU/mL. Liver cirrhosis was found in 35 (29.3%) patients and was more prevalent in patients who previously received treatment (71.0%). Interferon (IFN)-based treatment was started within 12 weeks from study inclusion in 12 (10.8%) patients, of whom 11 (91.7%) who had not previously received treatment. Anti-HCV treatment was not recommended by physicians in 70 (71.4%) and was refused by 23 (23.5%) patients. The MOSAIC study provides data on the epidemiology of HCV infection and IFN-based treatment decision patterns in Taiwan. Further studies are needed to observe the impact of IFN-free treatment on the treatment selection pattern.

Abstract
About 10 million people in China are infected with hepatitis C virus (HCV), with the seroprevalence of anti-HCV in the general population estimated at 0.6%. Delaying effective treatment of chronic hepatitis C (CHC) is associated with liver disease progression, cirrhosis, hepatocellular carcinoma, and liver-related mortality. The extrahepatic manifestations of CHC further add to the disease burden of patients. Managing CHC-related advanced liver diseases and systemic manifestations are costly for both the healthcare system and society. Loss of work productivity due to reduced well-being and quality of life in CHC patients further compounds the economic burden of the disease. Traditionally, pegylated-interferon plus ribavirin (PR) was the standard of care. However, a substantial number of patients are ineligible for PR treatment, and only 40%-75% achieved sustained virologic response. Furthermore, PR is associated with impairment of patient-reported outcomes (PROs), high rates of adverse events, and poor adherence. With the advent of direct acting antivirals (DAAs), the treatment of CHC patients has been revolutionized. DAAs have broader eligible patient populations, higher efficacy, better PRO profiles, fewer adverse events, and better adherence rates, thereby making it possible to cure a large proportion of all CHC patients. This article aims to provide a comprehensive evaluation on the value of effective, curative hepatitis C treatment from the clinical, economic, societal, and patient experience perspectives, with a focus on recent data from China, supplemented with other Asian and international experiences where China data are not available.

Abstract
OBJECTIVE Direct-acting antiviral agents (DAAs) have been approved for treating hepatitis C virus (HCV) infection in China. However, they are substantially more expensive. The current analysis will investigate the cost-effectiveness of novel regimens compared with pegylated interferon and ribavirin (PR) therapies for informing Chinese decision-makers. METHODS A Markov model was developed to measure economic and health outcomes of novel regimens for genotype 1b, 2, 3, and 6 HCV infections compared with PR treatment. Clinical, cost, and utility inputs were gathered from published sources. Discounted quality-adjusted life-years (QALYs), costs, and incremental cost-effectiveness ratios (ICERs) are shown. The uncertainty was facilitated by one-way and probabilistic sensitivity analyses. RESULTS For genotype 1b HCV infection, the combination of paritaprevir, ritonavir, ombitasvir and dasabuvir was cost-saving compared with four competing alternatives. The ICERs of sofosbuvir plus ribavirin for genotypes 2 and 3 were lower than the threshold ($18,234/QALY). Among available strategies for patients with genotype 6, sofosbuvir in combination with ribavirin was the cost-saving alternative compared with PR. The results were robust to sensitivity analyses. CONCLUSIONS For both genotype 1b and 6 HCV infections in the context of Chinese patients, there were combinations of DAAs that were cost-saving compared with the usual PR treatment, and cost-effective for genotypes 2 and 3.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common cancer and the second leading cause of cancer-related deaths worldwide. Sarcomatoid HCC is a rare histological subtype of HCC with largely unclear clinical manifestations and outcomes. We evaluated the clinical manifestations and outcomes of patients with sarcomatoid HCC. We identified 5,047 patients with histologically proven HCC from the Cancer Registry Database (1996-2016) of National Taiwan University Hospital. Among them, 40 patients with sarcomatoid HCC were identified from the pathology database of National Taiwan University Hospital. We included 160 patients with nonsarcomatoid HCC through propensity score matching according to sex, age, and Barcelona Clinic Liver Cancer stage. The majority of these patients with sarcomatoid HCC were men (75%); their median age was 58 years. Only 47.5% of the patients with sarcomatoid HCC presented with typical image patterns of HCC. The pathological grading of sarcomatoid HCC was more advanced compared with that of nonsarcomatoid HCC (42.5% vs. 23.8% in grade III and IV, P < 0.0001). The sarcomatoid group had significantly shorter median recurrence-free (13.3 vs. 84.2 months, log-rank P < 0.0001) and overall (8.3 vs. 69.3 months, log-rank P < 0.0001) survival than did the nonsarcomatoid group. The results of the multivariable Cox proportional hazard model revealed histological sarcomatoid subtype as an independent factor for all-cause mortality (hazard ratio [HR], 6.47; 95% confidence interval [CI], 3.12-13.43; P < 0.0001) and tumor recurrence (HR, 4.08; 95% CI, 1.72-9.66; P = 0.001). Conclusion: Compared with nonsarcomatoid HCC, sarcomatoid HCC was associated with more advanced histological grades and atypical image patterns. Histological sarcomatoid subtype is an independent predictor of tumor recurrence after curative treatment and all-cause mortality in patients with HCC.

Abstract
BACKGROUND AND OBJECTIVES Daclatasvir plus asunaprevir has shown superior efficacy and safety for treating hepatitis C virus genotype 1b infection in comparison with pegylated interferon and ribavirin. The objective of this analysis is to investigate the cost effectiveness of daclatasvir plus asunaprevir compared with interferon-α-based therapies from the perspective of the Chinese healthcare system. METHODS A Markov model was established to measure economic and health outcomes of daclatasvir plus asunaprevir compared with general interferon-α plus ribavirin and pegylated interferon plus ribavirin for hepatitis C virus genotype 1b infection. We also considered the two following scenarios: 24 weeks of daclatasvir plus asunaprevir used as a second-line treatment for ineligible/intolerant and non-responding patients with HCV during 48 weeks of first-line interferon-α plus ribavirin (interferon-α plus ribavirin and daclatasvir plus asunaprevir) or pegylated interferon plus ribavirin (pegylated interferon plus ribavirin and daclatasvir plus asunaprevir) treatment. Clinical costs and utility inputs were derived from the published literature. The incremental cost-effectiveness ratio was shown as costs in US dollars per quality-adjusted life-years gained. Uncertainty was examined by one-way and probabilistic sensitivity analyses. RESULTS Compared with interferon-α plus ribavirin, pegylated interferon and ribavirin, interferon-α plus ribavirin plus daclatasvir plus asunaprevir, and pegylated interferon plus ribavirin plus daclatasvir plus asunaprevir strategies, daclatasvir plus asunaprevir gained an additional 0.62, 0.32, 0.20, and 0.15 quality-adjusted life-year with increasing costs of US$11,950, US$671, US$8366, and -$3783, respectively. The incremental cost-effectiveness ratios of pegylated interferon and ribavirin, daclatasvir plus asunaprevir, interferon-α plus ribavirin and daclatasvir plus asunaprevir, and pegylated interferon plus ribavirin and daclatasvir plus asunaprevir against the baseline interferon-α plus ribavirin strategy were US$37,930, US$19,233, US$8495, and US$33,031 per quality-adjusted life-year gained. Daclatasvir plus asunaprevir and interferon-α plus ribavirin plus daclatasvir plus asunaprevir were presented as the cost-effective alternatives, and pegylated interferon plus ribavirin and pegylated interferon plus ribavirin and daclatasvir plus asunaprevir strategies dominated. The model outputs were sensitive to a patient's age, discount rate, and the risk ratio between pegylated interferon plus ribavirin and interferon-α plus ribavirin. CONCLUSIONS Daclatasvir plus asunaprevir in the Chinese setting is likely to be cost effective for treating hepatitis C virus genotype 1b infection.
