[PMID: 38675732 PMCID: PMC11054513 DOI: 10.3390/vaccines12040349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Revised: 03/11/2024] [Accepted: 03/21/2024] [Indexed: 04/28/2024] Open
Abstract
Vaccines prevent a significant number of deaths annually. However, certain populations do not respond adequately to vaccination due to impaired immune systems. Cirrhosis, a condition marked by a profound disruption of immunity, impairs the normal immunization process. Critical vaccines for cirrhotic patients, such as the hepatitis A virus (HAV), hepatitis B virus (HBV), influenza, pneumococcal, and coronavirus disease 19 (COVID-19), often elicit suboptimal responses in these individuals. The humoral response, essential for immunization, is less effective in cirrhosis due to a decline in B memory cells and an increase in plasma blasts, which interfere with the creation of a long-lasting response to antigen vaccination. Additionally, some T cell subtypes exhibit reduced activation in cirrhosis. Nonetheless, the persistence of memory T cell activity, while not preventing infections, may help to attenuate the severity of diseases in these patients. Alongside that, the impairment of innate immunity, particularly in dendritic cells (DCs), prevents the normal priming of adaptive immunity, interrupting the immunization process at its onset. Furthermore, cirrhosis disrupts the gut-liver axis balance, causing dysbiosis, reduced production of short-chain fatty acids (SCFAs), increased intestinal permeability, and bacterial translocation. Undermining the physiological activity of the immune system, these alterations could impact the vaccine response. Enhancing the understanding of the molecular and cellular factors contributing to impaired vaccination responses in cirrhotic patients is crucial for improving vaccine efficacy in this population and developing better prevention strategies.

Abstract
OBJECTIVE We aimed to compare the response rates between two different hepatitis B virus vaccination schedules for cirrhotic subjects who were non-responders to the first three 40 µg doses (month 0-1-2), and identify factors associated with the final response. DESIGN A total of 120 cirrhotic patients (72.5% decompensated) were randomised at a 1:1 ratio to receive a single 40 µg booster vaccination at month 6 (classical arm) versus an additional round of three new 40 µg doses administered at monthly intervals (experimental arm). The main outcome was the rate of postvaccinal anti-hepatitis B surface antibodies levels ≥10 mIU/mL. RESULTS Efficacy by ITT analysis was higher in the experimental arm (46.7%) than in the classical one (25%); OR 2.63, p=0.013. The experimental arm increased response rates compared with the classical one from 31% to 68% (OR 4.72; p=0.007), from 24.4% to 50% (OR 3.09; p=0.012) and from 24.4% to 53.8% (OR 3.62; p=0.007), in Child A, Model for End-Stage Liver Disease (MELD) <15 and MELD-Na<15 patients, respectively. Patients with more advanced liver disease did not benefit from the reinforced scheme. Both regimens showed similar safety profiles. Multivariable analysis showed that the experimental treatment was independently response associated when adjusted across three logistic regression models indicating equivalent cirrhosis severity. CONCLUSION For cirrhotic patients, the revaccination of non-responders to the first three dose cycle, with three additional 40 µg doses, achieved significantly better response rates to those obtained with an isolated 40 µg booster dose. TRIAL REGISTRATION NUMBER NCT01884415.

Abstract
In endemic areas, hepatitis C virus (HCV)/hepatitis B virus (HBV) coinfection is common, and patients with coinfection have a higher risk of developing liver disease such as hepatocellular carcinoma, liver fibrosis and cirrhosis. In such cases, HCV predominates, and HBV replication is suppressed by HCV. HCV core proteins and interferons that are activated by HCV are responsible for the suppression of HBV. Immunosuppression is also seen in patients with HCV and HBV coinfections. A decrease in HCV-neutralizing antibody response and circulation of Th1-like Tfh cells is observed in patients with HCV and HBV coinfection. Both viruses interacted in the liver, and treatment of HCV/HBV coinfection is genotype-based and complex due to the interaction of both viruses. In HCV-dominant cases, direct-acting antiviral drugs and peg interferon plus ribavirin are used for the treatment, with continuous monitoring of AST and ALT. HBV-dominant cases are less common and are treated with peg interferon and nucleoside nucleotide analogues with monitoring of AST and ALT. The SVR rate in HCV-HBV coinfection is higher than that in monoinfection when treated with direct-acting antiviral drugs. But there is a risk of reactivation of HBV during and after therapy. The rate of reactivation is lower in patients treated with direct-acting antiviral drugs as compared to those treated with peg interferon plus ribavirin. Biomarkers of HBV such as HBcrAg, HBV DNA and HBVpg RNA are not effective in the prediction of HBV reactivation; only the hepatitis B surface antigen titre can be used as a biomarker for HBV reactivation. HCV can also be reactive, but this is found in very rare cases in which HBV is present and is treated first.

Abstract
The interest in vaccination efficacy and toxicity has surged following the Covid-19 pandemic. Immune responses to several vaccines have been shown to be suboptimal in patients with chronic liver disease (CLD) or post-liver transplant (LT), as a consequence of cirrhosis-associated immune dysfunction (CAID) or post-LT immunosuppression respectively. Accordingly, vaccine-preventable infections may be more common or severe than in the general population. The Covid-19 pandemic has greatly accelerated research and development into vaccination technology and platforms, which will have spillover benefits for liver patients. The aims of this review are: (i) to discuss the impact of vaccine-preventable infections on CLD and post-LT patients, (ii) to appraise current evidence supporting vaccination strategies, and (iii) to provide some insight into recent developments relevant for liver patients.

Clinical study on the efficacy of hepatitis B vaccination in hepatitis C virus related chronic liver diseases in Egypt. Virus Res 2023; 323:198953. [PMID: 36209916 PMCID: PMC10194353 DOI: 10.1016/j.virusres.2022.198953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 06/28/2022] [Accepted: 09/30/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Chronic hepatitis B (HBV) and C virus (HCV) infections represent significant public health issues internationally. HBV vaccination has high sero-conversion rates in patients with mild to moderate chronic liver disease but has reduced efficacy in advanced stages. AIM to evaluate the efficacy of hepatitis B vaccination in HCV-related chronic liver disease and identify possible factors that may contribute to hypo-responsiveness in those patients. METHODS Our study was a retrospective observational clinical study carried out at the tropical medicine department. It was conducted on 500 individuals (400 chronic HCV patients and 100 healthy controls). Individuals were divided into 5 groups: A (control group), B (cirrhotic patient not receiving treatment), C (chronic hepatitis patients receiving treatment), D (cirrhotic patients receiving treatment), and E (HCC patients receiving treatment). All individuals were subjected for comprehensive history taking, clinical examination, laboratory investigations, and assessment of anti-HBs titer. RESULTS There is an inverse relationship between the level of anti-HBs Abs and the duration of vaccine. Diabetes and presence of cirrhosis have statistically significant relationship with serum anti-HBs Abs titer (P = 0.007). Oral DAAs therapy is associated with reduced response to HBV vaccine (only 31.75% of the patients were protected). CONCLUSION HCV infection and its complications significantly impair HBV vaccine response. Levels of anti-HBs Abs decline progressively with increasing duration from the last dose in immunization schedule of HBV vaccine. Diabetes and presence of cirrhosis being the main risk factors for vaccine hypo-responsiveness, also oral DAAs therapy is associated with reduced response to HBV vaccine.

Abstract
Patients with chronic liver disease (CLD) with or without cirrhosis remain at risk of developing hepatic decompensation when infected with viral or bacterial pathogens. The Advisory Committee on Immunization Practices (ACIP) currently recommends vaccination in CLD against hepatitis A virus (HAV), hepatitis B virus (HBV), influenza, pneumococcus, herpes zoster, tetanus, diphtheria, pertussis, and SARS-CoV-2. Inactivated vaccines are preferred over live attenuated ones, especially in transplant recipients where live vaccines are contraindicated. As the severity of the liver disease progresses, vaccine efficacy declines, and therefore, vaccines should be ideally administered early in the disease course for optimal immune response. Despite the strong recommendations, overall vaccination coverage in CLD remains poor; however, it is encouraging to note that in recent years coverage against influenza and pneumococcus has shown some improvement. Inadequate access to healthcare, lack of information on vaccine safety, poor financial reimbursement for healthcare providers, and vaccine misinformation are often responsible for low immunization rates. This review summarizes the impact of vaccine-preventable illness in those with CLD, updated vaccine guidelines, seroconversion rates in the vaccinated, and barriers faced by healthcare professionals in immunizing those with liver disease.

Abstract
BACKGROUND & AIMS Although HBV vaccine has a 95% seroconversion rate in the general population, patients with chronic liver disease have reduced seroconversion rates (16-79%). The aim of the study was to describe seroconversion rates with HBV vaccines in patients with chronic liver disease. APPROACH & RESULTS Retrospective chart review was performed among 652 patients who received a complete HBV vaccine series in the hepatology clinic. Of those, 126 patients that were included, 111 received a single dose series, and 15 patients received a double dose series. The seroconversion rate was overall low at 35%, and stayed the same at 35% with double dose and at 33% with single dose. Patients who received a single dose series were further analyzed to review risk factors for seroconversion. Overall, 65% of patients had cirrhosis. Patients were more likely to seroconvert if no cirrhosis (51% vs 72%, P=.04), higher aminotransferase levels, intermediate anti-HBs (2.5-11.9 mIU/mL) at baseline (87.5% vs 14%). CONCLUSION Patients with chronic liver disease had a low rate (35%) of response to HBV vaccination. The response rates did not improve in patients that received double dose series. Patients with cirrhosis, lower aminotransferase levels and with a lower baseline anti-HBs had decreased response rates.

Abstract
BACKGROUND There is an unmet need to improve the HBV vaccination status in patients with chronic liver diseases. Primary care physicians and outpatient hepatologists often fail to vaccinate as recommended. Thus, new strategies to improve the HBV vaccination rate are required. MATERIAL AND METHODS This study was performed in a cohort of patients with chronic liver diseases evaluated for liver transplantation. Vaccination status was taken from the patients' vaccination cards. HBsAg-, anti-HBc-, and anti-HBs-negative individuals were vaccinated against HBV at hospital discharge, and subsequent outpatient completion of the standard vaccination protocol was recommended in detail in the discharge letter. At months 2 and 8, titer controls were performed, and completion of vaccination was evaluated. RESULTS We prospectively recruited 37 patients. At baseline, the vaccination rate against HBV was 24% (N=9/37), and 3/9 HBV vaccinated patients presented with an anti-HBs-titer >10 IU/L. Thus, N=34 were vaccinated with Engerix® or Twinrix®. We evaluated 26/34 patients at month 2 and 10/26 again at month 8. The second vaccine dose was obtained by 21/26 (80%) of the patients seen at month 2, and 9/10 (90%) seen at month 8 obtained the third vaccine dose by primary care physicians or ambulant hepatologists. Only 2 patients presented with an anti-HBs-titer >10 IU/L at month 8. CONCLUSIONS Initiation of HBV vaccination during hospitalization and detailed recommendations on subsequent vaccinations in the discharge letter improve previously inadequate vaccination rates in the outpatient setting. Similar measures should be implemented at earlier time points of chronic liver diseases to achieve higher immune response rates.

Abstract
Almost all patients with hepatocellular carcinoma (HCC), a major type of primary liver cancer, also have liver cirrhosis, the severity of which hampers effective treatment for HCC despite recent progress in the efficacy of anticancer drugs for advanced stages of HCC. Here, we review recent knowledge concerning the molecular mechanisms of liver cirrhosis and its progression to HCC from genetic and epigenomic points of view. Because ~70% of patients with HCC have hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infection, we focused on HBV- and HCV-associated HCC. The literature suggests that genetic and epigenetic factors, such as microRNAs, play a role in liver cirrhosis and its progression to HCC, and that HBV- and HCV-encoded proteins appear to be involved in hepatocarcinogenesis. Further studies are needed to elucidate the mechanisms, including immune checkpoints and molecular targets of kinase inhibitors, associated with liver cirrhosis and its progression to HCC.

Here, we review recent knowledge concerning the molecular mechanisms of liver cirrhosis and its progression to HCC from genetic and epigenomic points of view. Because ~70% of patients with HCC have hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infection, we focused on HBV- and HCV-associated HCC. The literature suggests that genetic and epigenetic factors, such as microRNAs, play a role in liver cirrhosis and its progression to HCC, and that HBV- and HCV-encoded proteins appear to be involved in hepatocarcinogenesis. Further studies are needed to elucidate the mechanisms, including immune checkpoints and molecular targets of kinase inhibitors, associated with liver cirrhosis and its progression to HCC.

Abstract
Hepatitis B virus (HBV) and hepatitis C virus (HCV) coinfection is a complex clinical entity that has an estimated worldwide prevalence of 1-15%. Most clinical studies have shown that progression of disease is faster in HBV-HCV coinfected patients compared to those with monoinfection. Hepatocellular carcinoma development appears to have higher rate in coinfections. Viral replication in coinfected cells is characterized by a dominance of HCV over HBV replication. There are no established guidelines for treatment of HBV-HCV coinfection. Studies on interferon-based therapies and direct-acting antivirals have shown varying levels of efficacy. Clinical reports have indicated that treatment of HCV without suppression of HBV increases the risk for HBV reactivation. In this review, we appraise studies on both direct-acting antivirals and interferon-based therapies to evaluate the efficacy and rates of reactivation with each regimen. Screening for and prevention of coinfection are important to prevent serious HBV reactivations.

Abstract
The aim of the Mexican Consensus on the Treatment of HepatitisC was to develop clinical practice guidelines applicable to Mexico. The expert opinion of specialists in the following areas was taken into account: gastroenterology, infectious diseases, and hepatology. A search of the medical literature was carried out on the MEDLINE, EMBASE, and CENTRAL databases through keywords related to hepatitisC treatment. The quality of evidence was subsequently evaluated using the GRADE system and the consensus statements were formulated. The statements were then voted upon, using the modified Delphi system, and reviewed and corrected by a panel of 34 voting participants. Finally, the level of agreement was classified for each statement. The present guidelines provide recommendations with an emphasis on the new direct-acting antivirals, to facilitate their use in clinical practice. Each case must be individualized according to the comorbidities involved and patient management must always be multidisciplinary.

Hepatitis B virus reactivation during direct-acting antiviral therapy for hepatitis C: a systematic review and meta-analysis. Lancet Gastroenterol Hepatol 2018; 3:172-180. [PMID: 29371017 DOI: 10.1016/s2468-1253(18)30002-5] [Citation(s) in RCA: 113] [Impact Index Per Article: 18.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2017] [Revised: 12/03/2017] [Accepted: 12/04/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND Direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection might pose a risk for hepatitis B virus (HBV) reactivation in patients coinfected with chronic or resolved HBV infection. The need for HBV antiviral prophylaxis during DAA treatment remains controversial. We aimed to analyse the absolute risk of HBV reactivation in patients with active or resolved HBV infection treated with DAAs for HCV infection. METHODS For this systematic review and meta-analysis, we searched PubMed, Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and Web of Science from Oct 1, 2010, to Sept 30, 2017, to identify studies of patients with chronic or resolved HBV infection at baseline treated with DAAs for chronic HCV infection. Conference proceedings, abstract books, and references from relevant reviews were also examined for potential studies. Two independent researchers extracted data and assessed quality and risk of bias. Data were pooled by use of random-effects models. The primary outcome was HBV reactivation defined by standardised nomenclature. This study is registered with PROSPERO, number CRD42017065882. FINDINGS We identified 17 observational studies involving 1621 patients with chronic (n=242) or resolved (n=1379) HBV infection treated with different DAAs. The pooled proportion of patients who had HBV reactivation was 24% (95% CI 19-30) in patients with chronic HBV infection and 1·4% (0·8-2·4) in those with resolved HBV infection. In patients with chronic HBV infection, the pooled proportion of patients with HBV-reactivation-related hepatitis was 9% (95% CI 5-16) and the relative risk (RR) of HBV-reactivation-related hepatitis was significantly lower in patients with HBV DNA below the lower limit of quantification at baseline than in those with quantifiable HBV DNA (RR 0·17, 95% CI 0·06-0·50; p=0·0011). Three major clinical events related to HBV reactivation in patients with chronic HBV infection were reported (one patient had liver decompensation and two had liver failure, one of whom required liver transplantation). In patients with resolved HBV infection, no HBV-reactivation-related hepatitis was reported. INTERPRETATION HBV reactivation occurs frequently in patients with chronic HBV and HCV coinfection receiving DAA therapy but is rare among patients with resolved HBV infection. Use of antiviral prophylaxis might be warranted in patients who test positive for hepatitis B surface antigen (HBsAg), particularly those with quantifiable HBV DNA. FUNDING None.

Abstract
BACKGROUND & AIMS Exercise in overweight patients with liver disease has improved liver enzymes, insulin levels and quality of life. Scientific evidence is incomplete regarding the role of exercise in the prevention of cirrhosis. We investigated the effect of exercise on the occurrence of cirrhosis in obese and overweight adults. METHODS Exercise was assessed using the 2012 Adult Preventive Medical Service dataset while cirrhosis was identified using the National Health Insurance Research Database. All participants were aged 40 years and older. Unconditional logistic regression was used to estimate the odds ratios for cirrhosis. RESULTS Overall, 1586 overweight and 1525 obese adults were identified with cirrhosis. Weekly exercise >150 min was significantly protective for cirrhosis in obese men and women. However, exercise <150 min/wk was significantly protective only in men compared to women. For weekly exercise >150 mins, the odds ratio for cirrhosis in obese men and women was 0.701 (95% CI: 0.584-0.841) and 0.736 (95% CI: 0.562-0.964) respectively. The adjusted odds ratios in overweight men and women were 0.734 (95% CI: 0.622-0.866) and 0.503 (CI: 0.37-0.684). For weekly exercise <150 min/wk, overweight and obese men had odds ratios of 0.879 (CI: 0.0.788-0.98) and 0.874 (CI: 0.782-0.977) compared to 0.918 (95% CI: 0.778-1.083) and 0.916 (95% CI: 0.780-1.075) in overweight and obese women respectively. CONCLUSIONS Moderate exercise might significantly prevent obese and overweight adults from developing cirrhosis. The benefits appear to be greater for persons who exceed the minimum recommendations of 150 min/wk.

Abstract
This study aimed to explore crucial genes, transcription factors (TFs), and microRNAs (miRNAs) associated with the effects of curcumin against hepatocellular carcinoma (HCC). We downloaded data (GSE59713) from Gene Expression Omnibus to analyze differentially expressed genes (DEGs) between curcumin-treated and untreated HCC cell lines. Then, we identified the disease ontology (DO) and functional enrichment analysis of these DEGs and analyzed their protein-protein interactions (PPIs). Additionally, we constructed TF-target gene and miRNA-target gene regulatory networks and explored the potential functions of these DEGs. Finally, we detected the expression of CDKN1A, CTGF, LEF1 TF and MIR-19A regulated by curcumin in PLC/PRF/5 cells using RT-PCR. In total, 345 upregulated and 212 downregulated genes were identified. The main enriched pathway of upregulated genes was the TNF signaling pathway. The downregulated genes were significantly enriched in TGF-beta signaling pathway. In addition, most DEGs were significantly enriched in DO terms such as liver cirrhosis, hepatitis, hepatitis C and cholestasis (eg., CTGF). In the constructed PPI network, CDKN1A and CTGF were the key proteins. Moreover, LEF1, CDKN1A, and miR-19A that regulated CTGF were highlighted in the regulatory networks. Furthermore, the expression of CDKN1A, CTGF, LEF1 TF and miR-19A regulated by curcumin in PLC/PRF/5 cells was consistent with the aforementioned bioinformatics analysis results. To conclude, curcumin might exert its protective effects against HCC tumorigenesis by downregulating LEF1 and downregulating CTGF regulated by MIR-19A and upregulating CDKN1A expression.

Abstract
Background and Objective We characterize the burden of liver disease in a cohort of PWID in Chennai, India, with a high prevalence of HCV. Materials and Methods 1,042 PWID were sampled through community outreach in Chennai. Participants underwent fasting blood draw, questionnaire and an examination that included liver stiffness assessment using transient elastography (Fibroscan) and assessment of steatosis via ultrasound. Results The median age was 39 years, all were male, 14.8% were HIV infected and 35.6% were HCV antibody positive, of whom 78.9% were chronically infected (HCV RNA positive). Median liver stiffness was 6.2 kPA; 72.9% had no evidence of or mild stiffness, 14.5% had moderate stiffness, and 12.6% had evidence of severe stiffness/cirrhosis. Prevalence of severe stiffness/cirrhosis was significantly higher among persons who were older, had a longer duration of injecting drugs, higher body mass index, higher prevalence of insulin resistance, higher prevalence of steatosis, higher HCV RNA levels and evidence of alcohol dependence. An estimated 42.1% of severe stiffness/cirrhosis in this sample was attributable to HCV. 529 (53.0%) had some evidence of steatosis. Prevalence of steatosis was higher among those who had larger waist circumference, insulin resistance, higher HDL cholesterol and a history of antiretroviral therapy. Conclusions We observed a high burden of liver disease in this relatively young cohort that was primarily driven by chronic HCV infection, metabolic factors (insulin resistance and steatosis) and heavy alcohol use. Interventions to improve access to HCV treatment and reduce alcohol use are needed to prevent further progression of liver disease.

Microarray profiling shows distinct differences between primary tumors and commonly used preclinical models in hepatocellular carcinoma. BMC Cancer 2015; 15:828. [PMID: 26520397 PMCID: PMC4628260 DOI: 10.1186/s12885-015-1814-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2015] [Accepted: 10/16/2015] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Despite advances in therapeutics, outcomes for hepatocellular carcinoma (HCC) remain poor and there is an urgent need for efficacious systemic therapy. Unfortunately, drugs that are successful in preclinical studies often fail in the clinical setting, and we hypothesize that this is due to functional differences between primary tumors and commonly used preclinical models. In this study, we attempt to answer this question by comparing tumor morphology and gene expression profiles between primary tumors, xenografts and HCC cell lines. METHODS Hep G2 cell lines and tumor cells from patient tumor explants were subcutaneously (ectopically) injected into the flank and orthotopically into liver parenchyma of Mus Musculus SCID mice. The mice were euthanized after two weeks. RNA was extracted from the tumors, and gene expression profiling was performed using the Gene Chip Human Genome U133 Plus 2.0. Principal component analyses (PCA) and construction of dendrograms were conducted using Partek genomics suite. RESULTS PCA showed that the commonly used HepG2 cell line model and its xenograft counterparts were vastly different from all fresh primary tumors. Expression profiles of primary tumors were also significantly divergent from their counterpart patient-derived xenograft (PDX) models, regardless of the site of implantation. Xenografts from the same primary tumors were more likely to cluster together regardless of site of implantation, although heat maps showed distinct differences in gene expression profiles between orthotopic and ectopic models. CONCLUSIONS The data presented here challenges the utility of routinely used preclinical models. Models using HepG2 were vastly different from primary tumors and PDXs, suggesting that this is not clinically representative. Surprisingly, site of implantation (orthotopic versus ectopic) resulted in limited impact on gene expression profiles, and in both scenarios xenografts differed significantly from the original primary tumors, challenging the long-held notion that orthotopic PDX model is the gold standard preclinical model for HCC.

Abstract
Immunotherapy for cancer continues to gain both momentum and legitimacy as a rational mode of therapy and a vital treatment component in the emerging era of personalized medicine. Gliomas, and their most malignant form, glioblastoma, remain as a particularly devastating solid tumor for which standard treatment options proffer only modest efficacy and target specificity. Immunotherapy would seem a well-suited choice to address such deficiencies given both the modest inherent immunogenicity of gliomas and the strong desire for treatment specificity within the confines of the toxicity-averse normal brain. This review highlights the caveats and challenges to immunotherapy for primary brain tumors, as well as reviewing modalities that are currently used or are undergoing active investigation. Tumor immunosuppressive countermeasures, peculiarities of central nervous system immune access, and opportunities for rational treatment design are discussed.

Abstract
PURPOSE Alcohol is a confirmed risk factor of liver cancer. Yet, its dose-response function and synergistic effects with other risk factors remain unclear. METHODS We performed a meta-analysis on publications up to May 2014. A total of 112 publications were identified. The meta-relative risk (mRR) and the dose-response trend were calculated. Tests for heterogeneity, publication bias, and sensitivity analyses were performed. The synergy index (SI) was recorded or calculated, whenever possible. RESULTS Compared to individuals who never drank or drank at very low frequencies, the mRR for ever drinkers was 1.29 (95% confidence interval, CI 1.16-1.42) and 1.46 (95% CI 1.27-1.65) for case-control studies, and 1.07 (95% CI 0.87-1.27) for cohort studies. Being a current drinker was associated with an increased liver cancer risk in case-control studies (mRR = 1.55, 95% CI 0.38-2.73), but not in cohort studies (mRR = 0.86, 95% CI 0.74-0.97). The dose-response relation between alcohol and liver cancer was apparent with RR = 1.08 (95% CI 1.04-1.11) for 12 g/day (~1 drink), 1.54 (95% CI 1.36-1.74) for 50 g/day, 2.14 (95% CI 1.74-2.62) for 75 g/day, 3.21 (95% CI 2.34-4.40) for 100 g/day, and 5.20 (95% CI 3.25-8.29) for 125 g/day of alcohol consumption. There were synergistic effects of alcohol consumption with hepatitis (S = 2.14, 95% CI 1.31-2.98) and with diabetes (S = 3.57, 95% CI 2.29-4.84) on the risk of liver cancer, although this may be subject to publication bias. CONCLUSION Overall, one alcoholic drink per day (~12 g/day) may be associated with a 1.1 times higher liver cancer risk. Further studies on the synergistic effects of alcohol consumption and other major risk factors are warranted.

Abstract
Liver cancer is the fifth most common cancer, but the second leading cause of cancer death, in the world, with more than 700,000 fatalities annually. The major etiology of liver cancer is infection with an hepatotropic virus such as hepatitis B virus or hepatitis C virus infection. While chronic viral infection remains the main cause of liver disease and risk of hepatocellular carcinoma (HCC), rates of nonviral-associated HCC are occurring at an alarmingly increasing rate. Like many cancers, survival rates are closely associated with time of detection. If HCC is caught early, survival rates can be as high as 50%. Regrettably, most cases of HCC are caught late where survival rates can be as low as 2-7%. Thus, there has been great interest in discovering serum biomarkers that could be used to identify those with HCC. To this end, many groups have examined the N-linked glycans to identify changes that occur with HCC. As the liver secretes the vast majority of proteins into the serum, this has often been a starting point for study. In serum, alterations in core fucosylation, outer-arm fucosylation, increased sialylation, and glycan branching have been observed in patients with HCC. Similar findings have been found directly in HCC tissue suggesting that these glycan changes may play a role in tumor formation and development.

Abstract
BACKGROUND AND AIM Hepatocellular carcinoma (HCC) diagnosis could be made with one typical imaging study in a cirrhotic liver by the guideline of the American Association for the Study of Liver Diseases (AASLD) in 2010. Patients with hepatitis B who may not have fully developed cirrhosis could be applied. We aim to retrospectively analyze and validate the diagnostic power of the 2010 guideline in an HCC endemic area (Taiwan). METHODS From January 2006 to December 2010, a total of 648 patients with liver tumor post-surgical resection were reviewed. The fibrotic scores were verified by METAVIR score 4. Among the 648 patients, 569 (87.8%) were HCC patients. Hepatitis B accounts for 54.5%, hepatitis C 21.9%, hepatitis B + C 2.8%, and non-hepatitis B or C 20.7% of patients. Two hundred eighty-eight of 648 (44%) patients were with cirrhotic liver. RESULTS The diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value, and accuracy of the 2010 AASLD guideline f are 99.1%, 36.7%, 91.9%, 85.3%, and 91.5%, respectively. Cirrhotic liver exhibited a higher PPV (P < 0.001) but lower specificity (P = 0.0479) than non-cirrhotic liver. In both cirrhotic and non-cirrhotic condition, no difference existed in patients with hepatitis B or hepatitis C (P > 0.05). CONCLUSIONS Similar sensitivity of HCC diagnosis existed between cirrhotic and non-cirrhotic liver, and across different fibrotic stages. But cirrhotic liver exhibited a higher PPV. Hepatitis B or C has no decisive effect in HCC diagnosis.

Abstract
Hepatocellular carcinoma (HCC) is a development of severe liver disease frequently due to HBV and/or HCV infection. The aim of this retrospective study was to evaluate the development of HCC in patients with HBV-HCV chronic infection compared with patients with single HBV or HCV infection and the viral and host factors correlated to HCC in co-infected patients. We studied 268 patients with histology proven chronic hepatitis: 56 had HBV-HCV co-infection (HBV-HCV group), 46 had HBV infection (HBV group) and 166 had HCV infection (HCV group). Patients were followed up for at least 3 years. Viral and host factors were studied. HCC was more frequent in HBV-HCV group (14%) compared with HBV (2%, p = 0.006) and HCV monoinfected (4%, p = 0.006). The Mantel-Haenszel test used to investigate the relationship between HBV-HCV co-infection and development of HCC indicated an association between development of HCC and HBV-HCV co-infection (p < 0.001). In the HBV-HCV group, patients with HCC were significantly older (p = 0.000), had longer disease duration (p = 0.001), higher blood glucose levels (p = 0.001), lower levels of steatosis (p = 0.02), higher levels of fibrosis (p = 0.000), higher HCV RNA (p = 0.01) than those without HCC. ALT, lipid profile, PNPLA3 variant distribution and HBV viral load did not differ among co-infected patients with or without HCC. In conclusion HCC was more frequent in our patients with HBV-HCV co-infection, than in those with HBV or HCV mono-infection; possible associated risk factors for HCC development seem a long duration of disease, high levels of fibrosis and carbohydrate intolerance.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. Local metastasis is common but metastasis to the jaw is rare with 40 reported cases in the English language literature. REPORT OF CASE We describe a case of a 54-year-old man who, for the past two months, had noticed a rapidly growing facial mass in the posterior mandibular area. The patient was known to be a hepatitis C virus carrier and suffered from liver cirrhosis but the presence of HCC was unknown. METHODS AND RESULTS The English language literature was searched for documented cases of HCC metastasis to the jaw, applicable data was evaluated. The literature analysis revealed 41 reported cases (including the present case). In most cases (81%) the jaw lesion was the only known metastasis at the time of HCC diagnosis. Clinical presentation occurred up to 2 years before discovery of the jaw metastasis. Patients with HCC jaw metastasis have a poor survival rate with an average of 6.1 months between diagnosis and death. CONCLUSIONS This study shows that an isolated jaw mass may be the initial presentation of HCC and therefore must be considered in the differential diagnosis, especially in the presence of known liver cirrhosis or chronic viral hepatitis.

Abstract
UNLABELLED In patients with chronic hepatitis C (CHC), cirrhosis is associated with age, gender, diabetes, alcohol abuse, and coinfection with human immunodeficiency virus (HIV) or hepatitis B virus (HBV). The effect of these factors on the outcome of cirrhosis is unknown. This study in CHC patients with cirrhosis aimed to assess the influence of these factors on decompensation, liver transplantation, and death. Consecutive patients with CHC and cirrhosis hospitalized between January 1, 2006 and December 31, 2008 were followed up until death, transplantation, or study closure in March 2013. Gender, age, Model for End-Stage Liver Disease (MELD) score, diabetes, alcohol abuse, HIV, or HBV coinfection were collected at inclusion. The complications of cirrhosis, death, and liver transplantation were recorded at inclusion and during follow-up. The association between baseline factors and liver-related outcomes at inclusion and during follow-up were tested using logistic regression and Cox's model, respectively. A total of 348 patients with CHC and cirrhosis (68% men; median age: 59 years; median MELD: 10) were included. At baseline, 40% of the patients had diabetes, 29% alcohol abuse, and 6% HIV or HBV coinfection. Baseline MELD≥10 (P<0.001), diabetes (P=0.027), and HBV coinfection (P=0.001) were independently associated with transplantation-free survival. Baseline diabetes was independently associated with ascites (P=0.05), bacterial infections (P=0.001), and encephalopathy (P<0.001) at inclusion. Baseline diabetes was independently associated with development of ascites (P=0.057), renal dysfunction (P=0.004), bacterial infections (P=0.007), and hepatocellular carcinoma (P=0.016) during the follow-up. CONCLUSION In patients with CHC and cirrhosis, diabetes is an independent prognostic factor. Improving diabetes control may improve the outcome of cirrhosis.

Abstract
Hepatitis B and C (HBV and HCV) are hepatotropic viruses in humans with approximately 350 and 170 million chronic carriers respectively. Since both viruses have similar modes of transmission, many people are co-infected. Co-infection is common in intravenous drug users, HIV-positive individuals, and transplant recipients. Compared to mono-infected patients, co-infected patients exhibit exacerbated liver cirrhosis, hepatocellular carcinoma, and liver failure. Some of the pathogenic effects may be attributed in part to the structural core proteins of both viruses-ones that have displayed immunomodulatory properties. Yet, the effects of their combined interaction on the human immune system remain a mystery. We aimed to elucidate the combined effects of HBV and HCV core proteins on human dendritic cells' (DCs) ability to present antigens and stimulate antigen-specific T-cells. We observed that when DCs, differentiated from human peripheral blood monocytes, were co-incubated with both core proteins, IL-10 production was dramatically enhanced, IL-6, TNF-α, and IL-12 production was significantly reduced, and HLA-DR expression was downregulated. This instant functional and phenotypic modulation of DCs induced by a combination of HBV and HCV core proteins can allow them to behave like tolerizing DCs, inefficiently presenting antigens to CD4+ T-cells and even suppressing induction of the cellular immune response. These results reveal an important mechanism by which HBV and HCV synergistically induce immune tolerance early in infection that may be instrumental in establishing chronic, persistent infections.

Abstract
BACKGROUND There have been progressive increases in both the incidence and death rates of female patients with hepatocellular carcinoma (HCC). Our objective was to investigate the clinicopathologic characteristics and prognostic factors influencing the recurrence and survival of female patients with HCC. METHODS We performed a retrospective analysis of 459 consecutive female and 2,936 male patients with HCC who underwent curative resection. Multivariate competing risks analyses with Bonferroni correction were used to evaluate independent prognostic factors. RESULTS Female patients had a better overall survival rate (P = .001) than male patients, but a survival benefit was only observed in female patients with tumor-node-metastasis stage I diseases compared with male patients of the same stage (P = .023). Female patients less often had multiple tumors, vascular invasion, and larger tumors. Although female patients had a greater prevalence of increased serum alpha-fetoprotein (AFP), AFP and tumor number had prognostic significance only for male but not for female patients. The incidence of recurrence in female patients was not different than male patients (P = .130). Vascular invasion and serum γ-glutamyl transpeptidase level were independent risk factors for early recurrence of female patients, whereas AFP and γ-glutamyl transpeptidase level were independent risk factors for late recurrence. After curative treatment for recurrence, female patients still had a better overall survival than male patients (P = .025). CONCLUSION Female patients had a less invasive tumor phenotype and different prognostic factors from male patients. AFP had no prognostic value in female patients. Estrogen may have a protective effect against early- but not late-stage HCC. Female patients have a better outcome after curative resection of recurrent HCC.

Abstract
INTRODUCTION Patients with chronic hepatitis B virus (HBV)/hepatitis C virus (HCV) coinfection are at a high risk of developing liver cirrhosis and hepatocellular carcinoma, and consequently, warrant effective treatment. AREAS COVERED Effective treatment should eradicate HCV infection and inhibit HBV replication but without serious adverse reactions. Careful evaluation of disease progression, predominance of one virus over another, comorbidities and concomitant hepatitis delta virus and/or HIV infection are essential for better therapy choices. In the case of HCV predominance, Peg-interferon plus ribavirin with or without a first-generation directly acting antiviral (DAA) should be the first choice, but future treatments will be DAA-based and interferon-free. In the case of HBV predominance, tenofovir or entecavir should be part of treatment. Patients should be closely monitored for early identification and treatment of HCV or HBV reactivation. EXPERT OPINION High potency and high genetic barrier nucleos(t)ide analogues to inhibit HBV replication have been used for years, with no urgency for new drugs. Several DAAs for interferon-free therapy for HCV eradication will be available in the near future. We hope that the high cost of these drugs will not be a limitation to their use in developing countries. Further investigation of HBV/HCV interaction is needed before and during the administration of new therapies.

Abstract
Many studies have suggested that occult HBV infection has a substantial clinical relevance to hepatocellular carcinoma (HCC). Occult HBV infection is an important risk factor for the development of cirrhosis and HCC in patients without HBsAg. As a matter of fact, occult HBV infection is one of the most common causes of crytogenic HCC in endemic areas of HBV. However, there still are controversial issues about the association between occult HBV infection and HCC according to the underlying liver disease. In alcoholic cirrhosis, occult HBV infection may exert synergistic effect on the development of HCC. However, there is insufficient evidence to relate occult HBV infection to hepatocarcinogenesis in non-alcoholic fatty liver disease. In cryptogenic HCC, occult HBV infection may play a direct role in the development of HCC. In order to elucidate the assocciation between occult HBV infection and HCC, underlying liver disease must be specified and larger number of cases must be included in future studies.

Abstract
The purpose of this investigation was to evaluate the role of IL28-B polymorphism in the clearance of hepatitis C virus (HCV) in chronic hepatitis B virus (HBV)/HCV coinfection during a long-term follow-up. Thirty-four consecutive patients with HBV surface antigen (HBsAg)-positive/anti-HCV-positive chronic hepatitis were retrospectively enrolled at their first liver biopsy (LB). For all patients, a documented clinical, serological and virological follow-up of at least 3 years (range 3-16 years) after LB and a sample of whole blood for genetic evaluation were available. Of the 24 patients with detectable serum HBV-DNA and HCV-RNA at their first observation, three cleared both HBV-DNA and HCV-RNA, 12 HCV-RNA and five HBV-DNA. Of the seven HBV DNA-positive/HCV RNA-negative patients at enrolment, three cleared HBV-DNA and one remained HBV DNA-positive and became HCV RNA-positive. All three HBV DNA-negative/HCV RNA-positive patients remained unchanged. Compared with the 12 patients with HCV persistence, the 15 patients who cleared HCV were younger, had lower serum alanine aminotransferase (ALT), HCV load, and histological activity index (HAI) and fibrosis score, more frequently had IL28-B CC variant, had been receiving an interferon-based treatment and less frequently cleared serum HBV-DNA. To investigate the relationship between the IL28-B variants and clearance of HCV, excluding the confounding effect of interferon-based treatment, the Mantel-Haenszel test was used, which indicated an association between HCV clearance and IL28-B variants (p = 0.009). In chronic HBV/HCV coinfection, a long-term follow-up showed a frequent spontaneous or treatment-related clearance of active replication of one or both viruses and identified the IL28-B CC genotype as an independent predictor of HCV clearance.

Abstract
BACKGROUND/AIM To investigate the clinical features and treatment response in patients with hepatitis B (HBV) and hepatitis C virus (HCV) co-infection receiving anti-HCV therapy. PATIENTS AND METHOD Patients with HBV/HCV co-infection, who were eligible for anti-HCV therapy, were included in the study. Patients had detectable HBsAg for at least 6 months and detectable HCV-RNA before the initiation of therapy. Primary end-point was the proportion of patients achieving sustained virological response (SVR). HBV serology and HBV-DNA results obtained during the follow-up were assessed to determine HBV clearance or reactivation after anti-HCV therapy. RESULTS There were 612 patients in the HCV cohort and 52 (8.5%) of them were HBV/HCV co-infected. Twenty-eight patients (20 male, mean age: 47 ± 12) received anti-HCV treatment and followed-up for a mean duration of 53 months (12-156). Fifteen patients received peginterferon/ribavirin combination while the remaining patients received standard interferon/ribavirin combination (n=6) or standard interferon monotherapy (n=7). Patients receiving interferon monotherapy were under chronic hemodialysis therapy. SVR was achieved in 14 (50%) patients at the end of follow-up. The proportion of patients with SVR in three treatment arms were not significantly different (P=0.78). Eight of 11 patients with detectable HBV-DNA cleared HBV-DNA during treatment. Seven (25%) patients experienced a rebound in HBV-DNA, and one patient experienced an acute hepatitis flare which was controlled by tenofovir therapy. Two (7%) patients cleared HBsAg and one of them was seroconverted to anti-HBs. CONCLUSION Co-infection with HBV does not have a negative impact on the efficacy of anti-HCV treatment, but HBV-DNA should be monitored to overcome the risk of HBV exacerbation.

Abstract
Introduction. Patients with chronic liver disease (CLD) are more likely to have severe morbidity and fatality rate due to superimposed acute or chronic hepatitis B (HBV) infection. The literature has shown that hepatitis B vaccines are safe and effective in patients with CLD, but the data in cirrhosis liver is lacking. We assessed the safety and immunogenicity of HBV vaccine in patients with cirrhosis liver. Methods. CTP classes A and B CLD patients negative for hepatitis B surface antigen and antibody to hepatitis B core antigen were included. All patients received three doses of hepatitis B vaccine 20 mcg intramuscularly at 0, 30, and 60 days. Anti-HBs antibody was measured after 120 days. Results. 52 patients with mean age 47.48 ± 9.37 years were studied. Response rates in CTP classes A and B were 88% and 33.3%. We observed that the alcoholic chronic liver disease had less antibody response (44%) than other causes of chronic liver disease such as cryptogenic 69% and HCV 75%. Conclusions. Patients with cirrhosis liver will have low antibody hepatitis B titers compared to general population. As the age and liver disease progress, the response rate for hepatitis B vaccination will still remain to be weaker.

Abstract
BACKGROUND Chronic hepatitis C (CHC) infection is a risk factor for both the development of end-stage liver disease and hepatocellular carcinoma (HCC). Globally, approximately 170 million people are chronically infected with the hepatitis C virus (HCV), and the majority of these individuals come from the western Pacific and Southeast Asia regions (94.6 million persons combined). CHC is an understudied and underappreciated health problem in many Asian countries and in the US, where Asians represent one of the fastest growing groups of new Americans. AIM To perform a systematic review of the current literature on the epidemiology, diagnosis and screening, clinical characteristics and response to anti-viral therapy of Asians with CHC. METHODS Using a PubMed search of 'hepatitis C' and 'Asia,' 341 original manuscripts published in peer-reviewed journals were identified, and 99 were selected based on their relevance. RESULTS Many Asian CHC patients do not have easily identifiable risk factors and may be underdiagnosed. Rates of HCV infection in Asians on community screening in the US are unexpectedly high, and there is a high prevalence of HCV genotype 6 in Southeast Asia and Southern China. HCV-infected Asians tend to present at older age and may have higher risk of HCC; however, they respond better to anti-viral therapy than non-Asians across all HCV genotypes. CONCLUSIONS Given the high HCV endemicity in Asia, lack of identifiable risk factors and favourable treatment response rates in Asians, we advocate the screening for HCV infection of all Asians who come from areas where HCV prevalence is ≥2%.

Abstract
Chronic hepatitis B (CHB) is a dynamic disease that is influenced by host and virological factors. The management of CHB has become more complex with the increasing use of long-term oral nucleos⁄tide analogue antiviral therapies and the availability of novel diagnostic assays. Furthermore, there is often a lack of robust data to guide optimal management such as the selection of therapy, duration of treatment, potential antiviral side effects and the treatment of special populations. In November 2011, the Canadian Liver Foundation and the Canadian Association for the Study of the Liver convened a consensus conference to review the literature and analyze published data, including other international expert guidelines on CHB management. The proceedings of the consensus conference are summarized and provide updated clinical practice guidelines to assist Canadian health care providers in the prevention, diagnosis, assessment and treatment of CHB.

Abstract
INTRODUCTION Portal vein thrombosis is frequently associated with hepatocellular carcinoma (HCC). Tumor invasion into the portal vein by direct venous extension or metastasis occurs in up to 70% of HCC patients (Cedrone et al., Liver 16:94-8, 1996). However, presentation as an isolated malignant portal vein thrombosis without any evidence of obvious hepatoma-like lesions in the liver by imaging studies is extremely uncommon. We present an unusual case of HCC presenting as a malignant portal vein thrombus, proven on biopsy of the thrombus without any evidence of primary liver lesion. This, to our knowledge, is the first case of HCC presenting as an incidental isolated malignant portal vein thrombosis. The importance of doing delayed enhancement imaging studies to rule out malignant portal vein thrombosis is emphasized. CASE REPORT A 60-year-old man presented with acute substernal chest pain. Physical examination revealed icterus. Examination of the abdomen did not reveal any organomegaly. Liver function test revealed a predominantly conjugated bilirubinemia. Abdominal sonogram revealed thrombosis and occlusion of the posterior right portal vein. Liver parenchyma was homogenous with no intrahepatic mass. Computed tomography (CT) of the abdomen and pelvis after administration of oral and intravenous contrast with delayed views revealed arterial enhancement of the right portal vein thrombus with delayed washout. MRI of the abdomen with gadolinium confirmed the right portal vein thrombus without focal hepatic mass. Aspiration of the right portal vein thrombus under CT guidance revealed hepatocellular carcinoma which was confirmed by immunohistochemistry. Serum alpha-fetoprotein level was very high. Patient was started on sorafenib with subsequent decrease in alpha-fetoprotein level. He was doing well till the date of this report. DISCUSSION This unusual case of hepatocellular carcinoma presenting as an incidental malignant portal vein thrombosis without any primary liver lesion is extremely rare. Other reported cases of malignant portal vein thrombosis have been in patients with underlying hepatoma, cirrhosis, or with intrabiliary hepatocelluar carcinoma. In the clinical setting of portal vein thrombosis, imaging studies showing enhancement of the thrombus in the arterial phase are important in leading to the diagnosis of malignancy.

Abstract
Hepatitis B virus and hepatitis C virus are the two most common causes of chronic liver disease in the world. Dual infection with hepatitis B virus and hepatitis C virus, whose prevalence is underestimated, is characterized by a more severe liver injury, a higher probability of liver cirrhosis and a higher incidence of hepatocellular carcinoma. Treatment of these patients represents a therapeutic challenge. We report the case of an hepatitis B virus-hepatitis C virus co-infected patient, which particularly illustrates the interactions between these two viruses and therapeutic problems caused by the dual infection. HCV was initially dominant, which indicated a combination therapy by pegylated interferon and ribavirin. This treatment was associated with an early virological response of the HCV but an increase of HBV DNA occurred, requiring the use of a nucleoside analogue. A good response was obtained for the HBV but a relapse of HCV was noted, posing a problem for therapeutic decision.

Abstract
We evaluated tolerability and virological and clinical impact of anti-Hepatitis B Virus (HBV) nucleos(t)ide analogues in cirrhotic patients with HBV/Hepatitis C Virus (HCV) coinfection. The virological and clinical course of 24 consecutive HBsAg/HBV-DNA/anti-HCV-positive patients with cirrhosis was compared with that of 24 HBsAg/HBV-DNA-positive, anti-HCV-negative cirrhotic patients, pair-matched for age (±5 years), sex, HBeAg/anti-HBe status and Child-Pugh class. Patients in both groups were previously untreated with oral antiviral agents at enrollment and were treated for at least 24 months (range 24-54). At the 12th and 18th month of treatment, HBV-DNA was negative in 21 (87.5%) and 23 (95.8%) patients with hepatitis B and C and in 20 (83.3%) and 22 (91.6%) in patients with isolated HBV; all patients in both groups were HBV-DNA-negative at month 24 and at subsequent observations. Treatment was well tolerated by all patients in both groups. At the last observation (for co-infected patients, median 44 months and range 24-54; for mono-infected patients, median 40 months and range 24-54), a deterioration in Child class was observed in eight (47%) of 17 patients in patients with both HBV and HCV who were HCV-RNA-positive at baseline, but in none of seven HCV-RNA-negative patients in the same group, and in one patient (4.2%) in the mono-infected patients. Reactivation of HCV infection was relatively infrequent (12.5% of cases) and never associated with a clinical deterioration. Treatment with nucleotides in HBsAg/HBV-DNA/anti-HCV-positive patients with cirrhosis showed a favourable virological effect in all cases, but a favourable clinical result only in the HCV-RNA-negative at baseline.

Abstract
BACKGROUND AND AIMS The National Cancer Screening Program (NCSP) for liver cancer was initiated in 2003 in Korea. The objective of this study was to evaluate the participation rate of the program and to provide preliminary information on its results based on data collected by the NCSP in 2009. METHODS The target population of the NCSP for liver cancer in 2009 was comprised of 373,590 adults aged ≥40 years at high risk for liver cancer. Participation rates and positivity rates were assessed in this population. Multivariate logistic regression analysis was performed to determine the factors associated with participation in the NCSP for liver cancer. RESULTS The overall participation rate was 37.9% and 1,126 participants were positive at screening. The highest participation rates were observed in women, those in their 60s, National Health Insurance beneficiaries, and individuals positive for hepatitis B surface antigen. Positivity rates for men, those in their 70s, Medical Aid Program recipients and individuals with liver cirrhosis were the highest in the respective categories of gender, age, health insurance type, and risk factor for liver cancer. CONCLUSIONS The participation rates of the NCSP for liver cancer are still low, despite the fact that the program targets a high-risk group much smaller than the general population. Efforts to facilitate participation and to reduce disparities in liver cancer screening among Korean men and women are needed. These results provide essential data for evidence-based strategies for liver cancer control in Korea.

Single nucleotide polymorphisms and risk of hepatocellular carcinoma in cirrhosis. J Hepatol 2012; 57:663-74.

Abstract
Liver carcinogenesis is a complex and multi-factorial process, in which both environmental and genetic features interfere and contribute to malignant transformation. Patients with cirrhosis are particularly exposed and justify periodical screenings in order to detect the early development of hepatocellular carcinoma (HCC). The risk of HCC is, however, not identical from one patient to another. The identification of host factors that may also play an important role in HCC development may improve our understanding of the implications of the various biological pathways involved in liver carcinogenesis; such progress may as well help refine the selection of patients who could benefit from specific preventative measures or could be given adapted screening policies. Numerous candidate-gene studies have reported associations between single nucleotide polymorphisms (SNPs) and the presence of HCC. Some of these publications unfortunately suffer from major methodological drawbacks because of their case-control, retrospective and monocentric aspect. Prospective cohort studies conducted in large homogeneous populations and comprising a sufficient number of events during follow-up may overcome these pitfalls, but require a long time to be conducted and are still scarce. More recently, the first Genome Wide Association studies (GWAs) have enabled the identification of unsuspected loci that may be involved in various steps implicated in liver tumourigenesis. Taken together, these studies highlight variants that modulate oxidative stress, iron metabolism, inflammatory and immune responses, DNA repair mechanisms or systems involved in cell-cycle regulation as genetic traits susceptible to modify the natural history of cirrhotic patients and partly explain the observed differences in the risk of HCC occurrence. However, large genetic epidemiology studies in the field of cancer diseases have suggested the limited ability of polymorphic traits, alone, to refine individual prognosis. The integration of various panels of genes into clinical scores may in the near future define a "genomic risk prediction" specific to liver cancer developed in cirrhotic patients.

Abstract
Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections cause a wide range of liver diseases including hepatocellular carcinoma (HCC). Because of the similar modes of transmission, HBV HCV co-infections are found in approximately 7-20 million people globally. Compared with HBV or HCV mono-infections, co-infections are associated with more severe liver diseases and higher risk of HCC. Abnormal lipid biosynthesis and metabolism has been increasingly recognized as a cause for cancer. While HBV infection does not seem to significantly increase the risk of developing hepatic steatosis, steatosis is a prominent feature of chronic hepatitis C (CHC). In addition, steatosis in HBV or HCV mono-infections is a significant and independent risk factor for HCC. However, whether and how HBV HCV co-infections synergistically increase the risk of HCC development through modulating lipid metabolism is not well understood. Possible mechanisms by which steatosis causes HCC include: activation of sterol regulatory element-binding protein-mediated lipogenesis through the PI3K-Akt pathway, abnormal activation of peroxisome proliferator-activated receptors and endoplasmic reticulum stress. Here, we review the potential mechanisms by which HBV HCV co-infections may increase HCC risk through modulation of lipogenic gene expression. We begin with reviewing the impact of HBV and HCV on host lipogenic gene expression and carcinogenesis. We then discuss the potential mechanisms by which HBV and HCV can increase carcinogenesis through synergistically activating lipid biosynthesis and metabolism. We end by sharing our thoughts on future research directions in this emerging paradigm with an ultimate goal of developing effective therapeutics.

Abstract
UNLABELLED The guideline on the management of chronic hepatitis B (CHB) was first developed in 2004 and revised in 2007 by the Korean Association for the Study of the Liver (KASL). Since then there have been many developments, including the introduction of new antiviral agents and the publications of many novel research results from both Korea and other countries. In particular, a large amount of knowledge on antiviral resistance--which is a serious issue in Korea--has accumulated, which has led to new strategies being suggested. This prompted the new guideline discussed herein to be developed based on recent evidence and expert opinion. TARGET POPULATION The main targets of this guideline comprise patients who are newly diagnosed with CHB and those who are followed or treated for known CHB. This guideline is also intended to provide guidance for the management of patients under the following special circumstances: malignancy, transplantation, dialysis, coinfection with other viruses, pregnancy, and children.

Abstract
Dual and triple infections with hepatitis virus C (HCV), B (HBV) and D (HDV) frequently lead to severe liver damage. Hereby we describe a 38-year-old Caucasian male coinfected with HCV (genotype 3a), HBV [positive hepatitis B surface antigen (HbsAg) and antibody to hepatitis B core antigen; negative hepatitis B e antigen (HbeAg) and antibody to hepatitis B e antigen (anti-HBe)] and HDV. Laboratory diagnostics revealed increased liver enzymes and histological examination of the liver showed signs of fibrosis with moderate inflammation. On therapy with pegIFN-α2b and ribavirin HCV-RNA was undetectable at week 8. After week 24 the antiviral therapy was stopped because of a HBs-seroconversion, the loss of HbeAg and the detection of anti-HBe. Furthermore the HCV-RNA was negative. Six months after successful treatment of the triple-infection, HCV- and HDV-RNA and HbsAg remained negative and the liver enzymes had been completely normalized. In conclusion, pegylated-interferon plus ribavirin may be an effective therapy for HCV, HBV and HDV-coinfected patients.

Abstract
BACKGROUND Recent studies have indicated that interferon (IFN) or pegylated interferon (PEG-IFN) plus ribavirin therapy can achieve sustained virological response (SVR) against HCV equally in dual HBV-HCV infection and in HCV monoinfection. Whether these therapies can reduce hepatocellular carcinoma (HCC) development in dual HBV-HCV infection remains unclear. METHODS A total of 135 dually-infected patients with active hepatitis C receiving IFN or PEG-IFN plus ribavirin therapy were enrolled. The cumulative incidence of HCC was compared to that in 1,470 HCV-monoinfected patients. RESULTS Based on the Cox proportional hazards model, dual infection was an independent factor for HCC development in all 1,605 chronic hepatitis C patients with or without positive hepatitis B surface antigen receiving IFN or PEG-IFN plus ribavirin (hazard ratio (HR)=1.864, 95% CI 1.052-3.303; P=0.033). In dually-infected patients, HCC developed in 4 of 96 with HCV SVR and 11 of 39 without HCV SVR (P < 0.001) after a median follow-up of 4.6 years. Age (HR=1.175, 95% CI 1.070-1.291; P=0.001) and non-HCV-SVR (HR=7.874, 95% CI 2.375-26.32; P=0.001) were independent factors for HCC development. Subgroup analysis showed that HCC occurrence was lower in patients with HCV SVR and HBV DNA levels < 2,000 IU/ml at the end of treatment or follow-up compared to those with HCV SVR and HBV DNA levels ≥ 2,000 IU/ml (P=0.034) and those without HCV SVR (P<0.001). CONCLUSIONS Sustained HCV clearance by IFN or PEG-IFN plus ribavirin therapy may significantly reduce HCC in HBV-HCV dually-infected patients, whereas persistence or reactivation of HBV decreases the benefit of HCV SVR.
