BACKGROUND: Few comprehensive reviews on the pa- thogenesis of hepatitis C virus (HCV)-related liver diseases have been presented to the present. This article was to re- view the pathogenesis and treatment of HCV-related liver diseases. DATA SOURCES: Data presented here are mostly taken from Japanese studies. RESULTS: HCV infection is characterized by persistent in- flammation of the liver and frequent development of hepa- tocellular carcinoma (HCC) in most cases. These charac- teristic evidences could be explained by immunological al- terations and oxidative stress in the hepatocyte caused by HCV infection. Interferon (IFN) treatment is carried out, at present, not only for the elimination of infected HCV for the treatment of chronic liver diseases, but also for both the prevention of HCC and the treatment of advanced HCC with chemotherapy. The treatment for oxidative stress is al- so important for non-responders to IFN. CONCLUSION: It is important to understand the pathoge- nesis of HCV-related liver diseases for a successful treat- ment. 展开更多

In Japan,liver biopsies were previously crucial in evaluating the severity of hepatitis caused by the hepatitis C virus(HCV)and diagnosing HCV-related hepatocellular carcinoma(HCC).However,due to the development of effective antiviral treatments and advanced imaging,the necessity for biopsies has significantly decreased.This change has resulted in fewer chances for diagnosing liver disease,causing many general pathologists to feel less confident in making liver biopsy diagnoses.This article provides a comprehensive overview of the challenges and potential solutions related to liver biopsies in Japan.First,it highlights the importance of considering steatotic liver diseases as independent conditions that can coexist with other liver diseases due to their increasing prevalence.Second,it emphasizes the need to avoid hasty assumptions of HCC in nodular lesions,because clinically diagnosable HCCs are not targets for biopsy.Third,the importance of diagnosing hepatic immune-related adverse events caused by immune checkpoint inhibitors is increasing due to the anticipated widespread use of these drugs.In conclusion,pathologists should be attuned to the changing landscape of liver diseases and approach liver biopsies with care and attention to detail. 展开更多

At present chronic liver disease(CLD),the third commonest cause of premature death in the United Kingdom is detected late,when interventions are ineffective,resulting in considerable morbidity and mortality.Injury to the liver,the largest solid organ in the body,leads to a cascade of inflammatory events.Chronic inflammation leads to the activation of hepatic stellate cells that undergo transdifferentiation to become myofibroblasts,the main extra-cellular matrix producing cells in the liver;over time increased extra-cellular matrix production results in the formation of liver fibrosis.Although fibrogenesis may be viewed as having evolved as a“wound healing”process that preserves tissue integrity,sustained chronic fibrosis can become pathogenic culminating in CLD,cirrhosis and its associated complications.As the reference standard for detecting liver fibrosis,liver biopsy,is invasive and has an associated morbidity,the diagnostic assessment of CLD by non-invasive testing is attractive.Accordingly,in this review the mechanisms by which liver inflammation and fibrosis develop in chronic liver diseases are explored to identify appropriate and meaningful diagnostic targets for clinical practice.Due to differing disease prevalence and treatment efficacy,disease specific diagnostic targets are required to optimally manage individual CLDs such as non-alcoholic fatty liver disease and chronic hepatitis C infection.To facilitate this,a review of the pathogenesis of both conditions is also conducted.Finally,the evidence for hepatic fibrosis regression and the mechanisms by which this occurs are discussed,including the current use of antifibrotic therapy. 展开更多

The secosteroid hormone vitamin D has, in addition to its effects in bone metabolism also functions in the modulation of immune responses against infectious agents and in inhibiting tumorigenesis. Thus, deficiency of vitamin D is associated with several malignancies, but also with a plethora of infectious diseases. Among other communicable diseases, vitamin D deficiency is involved in the pathogenesis of chronic liver diseases caused by hepatitis B and C viruses(HBV, HCV) and high prevalence of vitamin D deficiency with serum levels below 20 mg/mL in patients with HBV and HCV infection are found worldwide. Several studies have assessed the effects of vitamin D supplementation on the sustained virological response(SVR) to interferon(IFN) plus ribavirin(RBV) therapy in HBV and HCV infection. In these studies, inconsistent results were reported. This review addresses general aspects of vitamin D deficiency and, in particular, the significance of vitamin D hypovitaminosis in the outcome of HBVand HCV-related chronic liver diseases. Furthermore,current literature was reviewed in order to understand the effects of vitamin D supplementation in combination with IFN-based therapy on the virological response in HBV and HCV infected patients. 展开更多

Delving into the immunological crossroads of liver diseases,this editorial explores the dynamic interplay between hepatitis C virus(HCV)and autoimmune hepatitis(AIH).While HCV primarily manifests as a viral infection impacting the liver,previous studies unveil a captivating connection between HCV and the emergence of AIH.The dance of the immune system in response to HCV appears to set the stage for an intriguing phenomenon-an aberrant autoimmune response leading to the onset of AIH.Evidence suggests a heightened presence of autoimmune markers in individuals with chronic HCV infection,hinting at a potential overlap between viral and autoimmune liver diseases.Navigating the intricate terrain of viral replication,immune response dynamics,and genetic predisposition,this editorial adds a layer of complexity to our understanding of the relationship between HCV and AIH.In this immunological crossroads,we aim to unearth insights into the complex interplay,using a compelling case where AIH and primary sclerosing cholangitis overlapped following HCV treatment with direct-acting antivirals as background. 展开更多

BACKGROUND Hepatitis C is the leading cause of chronic liver disease worldwide and it significantly contributes to the burden of hepatocellular carcinoma(HCC).However,there are marked variations in the incidence and mortality rates of HCC across different geographical regions.With the advent of new widely available treatment modalities,such as direct-acting antivirals,it is becoming increasingly imperative to understand the temporal and geographical trends in HCC mortality associated with Hepatitis C.Furthermore,gender disparities in HCC mortality related to Hepatitis C are a crucial,yet underexplored aspect that adds to the disease's global impact.While some studies shed light on gender-specific trends,there is a lack of comprehensive data on global and regional mortality rates,particularly those highlighting gender disparities.This gap in knowledge hinders the development of targeted interventions and resource allocation strategies.DISCUSSION The results of our study show an overall decline in the mortality rates of patients with hepatitis C-related HCC over the last two decades.Notably,females exhibited a remarkable decrease in mortality compared to males.Regionally,East Asia and the Pacific displayed a significant decline in mortality,while Europe and Central Asia witnessed an upward trend.Latin America and the Caribbean also experienced an increase in mortality rates.However,no significant difference was observed in the Middle East and North Africa.North America exhibited a notable upward trend.South Asia and Sub-Saharan Africa significantly declined throughout the study period.This raises the hope of identifying areas for implementing more targeted resources.Despite some progress,multiple challenges remain in meeting the WHO 2030 goal of eliminating viral hepatitis[24]. 展开更多

More than 90%of cases of hepatocellular carcinoma(HCC)occurs in patients with cirrhosis,of which hepatitis B virus and hepatitis C virus are the leading causes,while the tumor less frequently arises in autoimmune liver diseases.Advances in understanding tumor immunity have led to a major shift in the treatment of HCC,with the emergence of immunotherapy where therapeutic agents are used to target immune cells rather than cancer cells.Regulatory T cells(Tregs)are the most abundant suppressive cells in the tumor microenvironment and their presence has been correlated with tumor progression,invasiveness,as well as metastasis.Tregs are characterized by the expression of the transcription factor Foxp3 and various mechanisms ranging from cell-to-cell contact to secretion of inhibitory molecules have been implicated in their function.Notably,Tregs amply express checkpoint molecules such as cytotoxic T lymphocyte-associated antigen 4 and programmed cell-death 1 receptor and therefore represent a direct target of immune checkpoint inhibitor(ICI)immunotherapy.Taking into consideration the critical role of Tregs in maintenance of immune homeostasis as well as avoidance of autoimmunity,it is plausible that targeting of Tregs by ICI immunotherapy results in the development of immune-related adverse events(irAEs).Since the use of ICI becomes common in oncology,with an increasing number of new ICI currently under clinical trials for cancer treatment,the occurrence of irAEs is expected to dramatically rise.Herein,we review the current literature focusing on the role of Tregs in HCC evolution taking into account their opposite etiological function in viral and autoimmune chronic liver disease,and we discuss their involvement in irAEs due to the new immunotherapies. 展开更多

Hepatitis C virus(HCV) is a global health problem with an estimated 170-200 million peoples(approximately3% of world population) are chronically infected worldwide and new infections are predicted to be on rise in coming years. HCV infection remains categorized as a major risk factor for chronic hepatitis,liver cirrhosis and hepatocellular carcinoma worldwide. There has been considerable improvement in our understanding of virus life cycle since,the discovery of HCV two-decades ago.MicroRNAs(miRNAs) are important players in establishment of HCV infection and their propagation in infected hepatocytes. They target crucial host cellular factors needed for productive HCV replication and augmented cell growth.Very first anti-miRNA oligonucleotides,miravirsen has been tested in clinical trial and shown promising results as therapeutic agent in treatment against chronic HCV infection.Deregulated expression of miRNAs has been linked to the pathogenesis associated with HCV infection by controlling signaling pathways such as,proliferation,apoptosis and migration. Circulating miRNAs emerging as growing field in identification of biomarkers in disease progression and their potential as a means of communication between cells inside the liver is an exciting area of research in future.This review focuses on recent studies enforcing the contribution of miRNAs in HCV life cycle and coordinated regulation in HCV mediated liver disease progression. 展开更多

Alcohol consumption and hepatitis C virus(HCV) infection have a synergic hepatotoxic effect, and the coexistence of these factors increases the risk of advanced liver disease. The main mechanisms of this effect are increased viral replication and altered immune response, although genetic predisposition may also play an important role. Traditionally, HCV prevalence has been considered to be higher(up to 50%) in alcoholic patients than in the general po pulation. However, the presence of advanc e d alcoholic liver disease(ALD) or intravenous drug use(IDU) may have confounded the results of previous studies, and the real prevalence of HCV infection in alcoholic patients without ALD or prior IDU has been shown to be lower. Due to the toxic combined effect of HCV and alcohol, patients with HCV infection should be screened for excessive ethanol intake. Patients starting treatment for HCV infection should be specifically advised to stop or reduce alcohol consumption because of its potential impact on treatment efficacy and adherence and may benefi t from addi tionalsupport during antiviral therapy. This recommendation might be extended to all currently recommended drugs for HCV treatment. Patients with alcohol dependence and HCV infection, can be treated with acamprosate, nalmefene, topiramate, and disulfiram, although baclofen is the only drug specifically tested for this purpose in patients with ALD and/or HCV infection. 展开更多

AIM: To study the significance and clinical implication of hepatic lipogranuloma in chronic liver diseases, including fatty liver disease and hepatitis C. METHODS: A total of 376 sequential, archival liver biopsy specimens were reviewed. Lipogranuloma, steatosis and steato-fibrosis were evaluated with combined hematoxylin and eosin and Masson’s trichrome staining. RESULTS: Fifty-eight (15.4%) patients had lipogranuloma, including 46 patients with hepatitis C, 14 patients with fatty liver disease, and 5 patients with other diseases. Hepatic lipogranuloma was more frequently seen in patients with hepatitis C (21%) and fatty liver disease (18%), and its incidence was significantly higher than that in control group (P < 0.0002 and P < 0.007, respectively). In addition, 39 out of the 58 patients with lipogranuloma were associated with steatosis and/or steato-fibrosis. Of the 18 lipogranuloma patients with clinical information available for review, 15 (83%) had risk factors associated with fatty liver disease, such as alcohol use, obesity, hyperlipidemia, and diabetes mellitus. Although the incidence of these risk factors was greater in patients with lipogranuloma than in control group (60%), it did not reach statistical significance. CONCLUSION: Hepatic lipogranuloma is not limited to mineral oil use and commonly associated with hepatic steatosis, hepatitis C and fatty liver disease. With additional histological features of steato-fibrosis, lipogranuloma can also be used as a marker of prior hepatic steatosis. 展开更多

AIM: To assess the prevalence of the two mutations, C282Y and H63D of HFE gene, in healthy subjects, patients with chronic hepatitis C (CHC), and patients with nonalcoholic fatty liver disease (NAFLD) in Taiwan and to explore the contribution of the HFE mutation on serum iron stores in CHC and NAFLD groups.METHODS: We examined C282Y and H63D mutations of HFE gene in 125 healthy subjects, 29 patients with CHC,and 33 patients with NAFLD. The serum iron markers,including ferritin, iron, and total iron binding capacity (TIBC),were assessed in all patients.RESULTS: All of the healthy subjects and patients were free from C282Y mutation. The prevalence of H63D heterozygosity was 4/125 (3.20%) in healthy subjects, 2/29(6.90%) in CHC group, and 1/33 (3.03%) in NAFLD group.The healthy subjects showed no significant difference in the prevalence of H63D mutation as compared with the CHC or NAFLD group. Increased serum iron store was found in 34.48% of CHC patients and 36.36% of NAFLD patients.In three patients of H63D heterozygosity, only one CHC patient had increased serum iron store. There was no significant difference in the prevalence of HFE mutations between patients with increased serum iron store and those without in CHC or NAFLD group.CONCLUSION: The HFE mutations may not contribute to iron accumulation in the CHC or NAFLD group even when serum iron overload is observed in more than one-third of these patients in Taiwan. 展开更多

AIM:To examine trends in and correlates of liver disease and viral hepatitis in an human immunodeficiency virus (HIV)-infected cohort. METHODS:The multi-site adult/adolescent spectrum of HIV-related diseases (ASD) followed 29 490 HIVinfected individuals receiving medical care in 11 U.S. metropolitan areas for an average of 2.4 years,and a total of 69 487 person-years,between 1998 and 2004. ASD collected data on the presentation,treatment,and outcomes of HIV,including liver disease,hepatitis screening,and hepatitis diagnoses. RESULTS:Incident liver disease,chronic hepatitis B virus (HBV),and hepatitis C virus (HCV) were diagnosed in 0.9,1.8,and 4.7 per 100 person-years. HBV and HCV screening increased from fewer than 20% to over 60% during this period of observation (P < 0.001). Deaths occurred in 57% of those diagnosed with liver disease relative to 15% overall (P < 0.001). Overall 10% of deaths occurred among individuals with a diagnosis of liver disease. Despite care guidelines promoting screening and vaccination for HBV and screening for HCV,screening and vaccination were not universally conducted or,if conducted,not documented. CONCLUSION:Due to high rates of incident liver disease,viral hepatitis screening,vaccination,and treatment among HIV-infected individuals should be a priority. 展开更多

Alcoholic liver disease(ALD) and hepatitis C virus(HCV) infection represent, either alone or in combination, more than two thirds of all patients with liver disease in the Western world.This review discusses the epidemiology and combined impact of ALD and HCV on the progres sion of liver disease.ALD and HCV affect the progres sion of liver disease to liver cirrhosis and hepatocellular carcinoma(HCC) in a synergistic manner.Thus, the risk for HCC increases f ive times with a daily alcohol con sumption of 80 g;in the presence of HCV it is increased 20fold, and a combination of both risk factors leads to a more than 100fold risk for HCC development.Alcohol consumption also decreases the response to interferon treatment which is probably due to a lack of compliance than a direct effect on HCV replication.Several molecu lar mechanisms are discussed that could explain the synergistic interaction of alcohol and HCV on disease progression.They include modulation of the immune response and apoptosis, increased oxidative stress via induction of CYP2E1 and the hepatic accumulation of iron.Thus, both HCV and alcohol independently cause hepatic iron accumulation in > 50% of patients probably due to suppression of the liversecreted systemic iron hormone hepcidin.A better understanding of hepcidin regulation could help in developing novel therapeutic approaches to treat the chronic disease in the future.For now, it can be generally concluded that HCVinfect ed patients should abstain from alcohol and alcoholicsshould be encouraged to participate in detoxification programs. 展开更多

AIM: Clinical and experimental data suggest that gut-derived endotoxins are an important pathogenic factors for progression of chronic liver disease. Recently, a C-T (-159)polymorphism in the promoter region of the CD14 gene was detected and found to confer increased CD14 expression and to be associated with advanced alcoholic liver damage. Here, we investigated this polymorphism in patients with less advanced alcoholic liver disease (ALD)and chronic hepatitis C virus (HCV) infection.METHODS: CD14 genotyping was performed by PCR-RFLP analysis in (a) 121 HCV patients, (b) 62 patients with alcohol-associated cirrhosis (Alc-Ci), (c) 118 individuals with heavy alcohol abuse without evidence of advanced liver damage (Alc-w/o Ci), and (d) 247 healthy controls.Furthermore, serum levels of soluble CD14 (sCD14) and transaminases were determined.RESULTS: The TT genotype was significantly more frequent in Alc-Ci compared to Alc-w/o Ci or controls (40.3% vs 23.7% or 24.0%, respectively). In Alc-w/o Ci,serum levels of transaminases did not differ significantly between patients with different CD14 genotypes. In HCV patients, TT-homozygotes had significantly higher sCD14 levels and sCD14 serum levels were significantly higher in patients with advanced fibrosis or cirrhosis. However,no association was found between CD14 genotypes and histological staging or grading.CONCLUSION: Considering serum transaminases as surrogate markers for alcoholic liver damage, the CD14 polymorphism seems to exhibit different effects during the course of ALD. Differences in genotype distribution between cirrhotic HCV patients and alcoholics and the known functional impact of this polymorphism on CD14 expression levels further indicate differences in the pathophysiological role of CD14 and CD14-mediated lipopolysaccharides signal transduction with regard to the stage as well as the type of the underlying liver disease. 展开更多

AIM To assess liver fibrosis(LF) in hepatitis C virus(HCV) and alcoholic liver disease(ALD), estimate health outcomes and costs of new noninvasive testing strategies METHODS A Markov model was developed to simulate LF progression in HCV and ALD for a cohort of 40-yearold men with abnormal levels of transaminases. Three different testing alternatives were studied: a single liver biopsy; annual Enhanced liver fibrosis(ELF?) followed by liver stiffness measurement(LSM) imaging as a confirmation test if the ELF test is positive; and annual ELF test without LSM. The analysis was performed from the perspective of a university hospital in Spain.Clinical data were obtained from published literature. Costs were sourced from administrative databases of the hospital. Deterministic and probabilistic sensitivity analyses were performed.RESULTS In HCV patients, annual sequential ELF test/LSM and annual ELF test alone prevented respectively 12.9 and 13.3 liver fibrosis-related deaths per 100 persons tested, compared to biopsy. The incremental costeffectiveness ratios(ICERs) were respectively €13400 and €11500 per quality-adjusted life year(QALY). In ALD, fibrosis-related deaths decreased by 11.7 and 22.1 per 100 persons tested respectively with sequential ELF test/LSM and annual ELF test alone. ICERs were €280 and €190 per QALY, respectively.CONCLUSION The use of the ELF test with or without a confirmation LSM are cost-effective options compared to a single liver biopsy for testing liver fibrosis in HCV and ALD patients in Spain. 展开更多

AIM: The significance of hepatitis C virus (HCV) serum titers has been examined in several clinical situations.There is much evidence that patients with a lower viral load have better response rates to anti-viral therapy compared to those with higher levels. Moreover, a direct association has been observed between serum titers of HCV and transmission rates of the virus. The aim of the present study was to determine if there was any correlation between HCV viral load and the severity of liver disease.METHODS: Fifty patients with HCV infection were includedin the study. These comprised of 34 subjects with a history of alcohol use and 16 non-alcoholics. Quantitative serum HCV RNA assay was carried out using the branched DNA (bDNA) technique. Linear regression analysis was performed between serum viral titers and liver tests. In addition, for the purpose of comparison, the subjects were divided into two groups: those with low viral titers (≤50 genome mEq/mL)and high titers (>50 mEq/mL).RESULTS: All subjects were men, with a mean±SD ageof 47±7.8 years. The mean HCV RNA level in the blood was 76.3×10^5±109.1 genome equivalents/mL. There was no correlation between HCV RNA levels and age of the patients (r = 0.181), and the history or amount (g/d) of alcohol consumption (r = 0.07). Furthermore, no correlation was observed between serum HCV RNA levels and the severity of liver disease as judged by the values of serum albumin (r= 0.175), bilirubin (r = 0.217), ALT (r= 0.06) and AST(r = 0.004) levels. Similarly, no significant difference was observed between patients with low viral titers and high titers with respect to any of the parameters.CONCLUSION: Our results indicate that the severity of liver disease is independent of serum levels of hepatitis C virus. These findings are important since they have a direct impact on the current debate regarding the role of direct cytopathic effect of hepatitis C virus versus immune-mediated injury in the pathogenesis of HCV-related liver damage. 展开更多

AIM: To determine the prevalences of TTV and HGV infections among blood donors and patients with chronic liver disease in Korea, to investigate the association of TTV and HGV infections with blood transfusion, and to assess the correlation between TTV and HGV viremia and hepatic damage.METHODS: A total of 391 serum samples were examined in this study. Samples were obtained from healthy blood donors (n= 110), hepatitis B surface antigen (HBsAg)-positive donors (n=112), anti-hepatitis C virus (anti-HCV)-positive donors (n=69), patients with type B chronic liver disease (n=81), and patients with type C chronic liver disease (n= 19).TTV DNA was detected using the hemi-nested PCR. HGV RNA was tested using RT-PCR. A history of blood transfusion and serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were also determined.RESULTS: TTV DNA was detected in 8.2 % of healthy blood donors, 16.1% of HBsAg-positive donors, 20.3 % of antiHCV-positive donors, 21.0 % of patients with type B chronic liver disease, and 21.1% of patients with type C chronic liver disease. HGV RNA was detected in 1.8 % of healthy blood donors, 1.8 % of HBsAg-positive donors, 17.4 % of anti-HCV-positive donors, 13.6% of patients with type B chronic liver disease, and 10.5% of patients with type C chronic liver disease. The prevalence of TTV and HGV infections in HBV- or HCV-positive donors and patients was significantly higher than in healthy blood donors (P<0.05),except for the detection rate of HGV in HBsAg-positive donors which was the same as for healthy donors. There was a history of transfusion in 66.7% of TTV DNA-positive patients and 76.9% of HGV RNA-positive patients (P<0.05). No significant increase in serum ALT and AST was detected in the TTV- or HGV-positive donors and patients.CONCLUSION: TTV and HGV infections are more frequently found in donors and patients infected with HBV or HCV than in healthy blood donors. However, there is no significant association between TTV or HGV infections and liver injury. 展开更多

Chronic infections with the hepatitis B and C viruses have significant worldwide health and economic impacts.Previous treatments for hepatitis C such as interferon and ribavirin therapy were ineffective and poorly tolerated by patients.The introduction of directly acting curative antiviral therapy for hepatitis C and the wider use of nucleos(t)ide analogues for suppression of chronic Hepatitis B infection have resulted in many positive developments.Decreasing the prevalence of hepatitis B and C have concurrently reduced transmission rates and hence,the number of new infections.Antiviral treatments have decreased the rates of liver decompensation and as a result,lowered hospitalisation and mortality rates for both chronic hepatitis B and C infection.The quality of life of chronically infected patients has also been improved significantly by modern treatment.Antiviral therapy has stopped the progression of liver disease to cirrhosis in certain patient cohorts and prevented ongoing hepatocellular damage in patients with existing cirrhosis.Longer term benefits of antiviral therapy include a reduced risk of developing hepatocellular carcinoma and decreased number of patients requiring liver transplantation.This review article assesses the literature and summarises the impact of modern antiviral therapy of chronic hepatitis B and C on clinical outcomes from liver disease. 展开更多

Background: Post hepatitis C virus chronic liver disease (CLD) is prevalent among the Egyptian population with a bad impact upon their quality of life (QOL). Hepatocellular carcinoma (HCC) is one of the long term and fatal complications of CLD and it also has its negative impact on patient’s quality of life. Aim: To assess impact of CLD and HCC on the quality of life of group of hospitalized elderly patients. Methodology: Ninety elderly patients were divided into three groups: 30 elderly with post hepatitis C virus CLD, 30 elderly with HCC and 30 others free of liver disease as control group (Cn), all were recruited from the in-patient ward and the outpatient clinic of the Geriatric Department, Ain-Shams University Hospital. After giving consent, comprehensive geriatric assessment was done with assessment of their quality of life by using the Short Form-36 health survey (SF-36). Investigations including liver enzymes, serum albumin, serum bilirubin and abdominal ultrasound were done. Results: All QOL domains were the highest among control group, followed by HCC group and the least among CLD group. The differences were statistically significant in most subscales and total score [Mean of Cn = 81.9 ± 12.4, Mean of CLD = 47.5 ± 21.9, Mean of HCC = 62.3 ± 16.1;P Cn/CLD ≤ 0.001, P Cn/HCC ≤ 0.001, P CLD/HCC = 0.004]. Albumin was the only biochemical marker correlated positively with total SF score and two subscales (PF and EF) [r = 0.408;P = 0.025]. Conclusion & Recommendation: Our study showed a decrease in the QOL of Egyptian post hepatitis C virus CLD and HCC patients compared with Egyptian population norms. The results showed that CLD were more affected than HCC patients. This had a particularly serious negative impact on their life. The findings indicate a need for updated counseling and educational materials designed to provide adequate information and consistent healthcare service to this patient setting. 展开更多
