Abstract
BACKGROUND Vaccine hesitancy and lack of access remain major issues in disseminating COVID-19 vaccination to liver patients globally. Factors predicting poor response to vaccination and risk of breakthrough infection are important data to target booster vaccine programs. The primary aim of the current study was to measure humoral responses to 2 doses of COVID-19 vaccine. Secondary aims included the determination of factors predicting breakthrough infection. METHODS COVID-19 vaccination and Biomarkers in cirrhosis And post-Liver Transplantation is a prospective, multicenter, observational case-control study. Participants were recruited at 4-10 weeks following first and second vaccine doses in cirrhosis [n = 325; 94% messenger RNA (mRNA) and 6% viral vaccine], autoimmune liver disease (AILD) (n = 120; 77% mRNA and 23% viral vaccine), post-liver transplant (LT) (n = 146; 96% mRNA and 3% viral vaccine), and healthy controls (n = 51; 72% mRNA, 24% viral and 4% heterologous combination). Serological end points were measured, and data regarding breakthrough SARS-CoV-2 infection were collected. RESULTS After adjusting by age, sex, and time of sample collection, anti-Spike IgG levels were the lowest in post-LT patients compared to cirrhosis (p < 0.0001), AILD (p < 0.0001), and control (p = 0.002). Factors predicting reduced responses included older age, Child-Turcotte-Pugh B/C, and elevated IL-6 in cirrhosis; non-mRNA vaccine in AILD; and coronary artery disease, use of mycophenolate and dysregulated B-call activating factor, and lymphotoxin-α levels in LT. Incident infection occurred in 6.6%, 10.6%, 7.4%, and 15.6% of cirrhosis, AILD, post-LT, and control, respectively. The only independent factor predicting infection in cirrhosis was low albumin level. CONCLUSIONS LT patients present the lowest response to the SARS-CoV-2 vaccine. In cirrhosis, the reduced response is associated with older age, stage of liver disease and systemic inflammation, and breakthrough infection with low albumin level.

Abstract
Mongolia has one of the highest viral hepatitis infection (B, C, and D) rates in the world. The aims of this study were to increase awareness of this disease and promote viral hepatitis screening in the Mongolian community living in Spain. Through a native community worker, Mongolian adults were invited to a community program consisting of an educational activity, an epidemiological questionnaire, and rapid point-of-care testing for hepatitis B and C. In those testing positive, blood extraction was performed to determine serological and virological parameters. In total, 280 Mongolians were invited to the program and 222 (79%) attended the event: 139 were women (63%), mean age was 42 years, and 78 (35%) had viral hepatitis risk factors. Testing found 13 (5.8%) anti-HCV-positive individuals, 1 with detectable HCV RNA (0.5%), 8 HBsAg-positive (3.6%), and 7 with detectable HBV DNA (3.1%). One additional individual had HBV/HCV co-infection with detectable HBV DNA and HCV RNA. Two subjects had hepatitis B/D co-infection (0.9%). The knowledge questionnaire showed a 1.64/8-point (20.5%) increase in correct answers after the educational activity. In summary, a viral hepatitis community program was feasible and widely accepted. It increased awareness of this condition in the Mongolian community in Spain and led to linkage to care in 22 participants, 50% of whom were unaware of their infection.

Abstract
IntroductionCellular epigenetic modifications occur in the course of viral infections. We previously documented that hepatitis C virus (HCV) infection of human hepatoma Huh-7.5 cells results in a core protein-mediated decrease of Aurora kinase B (AURKB) activity and phosphorylation of Serine 10 in histone H3 (H3Ser10ph) levels, with an affectation of inflammatory pathways. The possible role of HCV fitness in infection-derived cellular epigenetic modifications is not known.MethodsHere we approach this question using HCV populations that display a 2.3-fold increase in general fitness (infectious progeny production), and up to 45-fold increase of the exponential phase of intracellular viral growth rate, relative to the parental HCV population.ResultsWe show that infection resulted in a HCV fitness-dependent, average decrease of the levels of H3Ser10ph, AURKB, and histone H4 tri-methylated at Lysine 20 (H4K20m3) in the infected cell population. Remarkably, the decrease of H4K20m3, which is a hallmark of cellular transformation, was significant upon infection with high fitness HCV but not upon infection with basal fitness virus.DiscussionHere we propose two mechanisms ─which are not mutually exclusive─ to explain the effect of high viral fitness: an early advance in the number of infected cells, or larger number of replicating RNA molecules per cell. The implications of introducing HCV fitness as an influence in virus-host interactions, and for the course of liver disease, are warranted. Emphasis is made in the possibility that HCV-mediated hepatocellular carcinoma may be favoured by prolonged HCV infection of a human liver, a situation in which viral fitness is likely to increase.

Abstract
BACKGROUND Spontaneous HDV-RNA fluctuations, assessed by nonstandardised in-house assays, have been reported during the course of chronic hepatitis delta (CHD). AIMS To evaluate changes in serum HDV-RNA concentrations in untreated CHD patients and correlate these changes with other HBV markers. METHODS A total of 323 consecutive serum samples from 56 CHD patients (detectable HDV-RNA) followed for >3 years were retested for HDV-RNA levels by a sensitive technique using the first WHO international HDV-RNA standard. Quantitative HBsAg, HBV-DNA, and HBV-RNA were also determined. RESULTS Most participants were male, middle-aged, white European, and HBeAg-negative (82%). Almost half had liver cirrhosis and 64% were receiving nucleos(t)ide analogues. At inclusion, median-HDV-RNA was 5.3 (4.2-6.5) log10 IU/mL, HBsAg 4.0 (3.5-4.3) log10 IU/mL, and HBV-DNA 1.6 (1.0-2.6) log10 IU/mL; ALT values were normal in 13 (23%). During a mean follow-up of 5.6 (3-16) years, 14 (25%) showed ≥2log10 HDV-RNA decline, including 11 (20%) who spontaneously achieved undetectable HDV-RNA. Four patients (7%) lost HBsAg, with undetectable HDV-RNA. The remaining 42 (75%) had persistently detectable HDV-RNA. During follow-up, patients with a ≥2log10 HDV-RNA decline showed a greater HBsAg drop (-0.7 ± 1.1 vs -0.09 ± 0.9 log IU/mL; P = 0.039) than those with a <2 log10 HDV-RNA decline. Overall, ALT and HBV-DNA levels decreased over time. There were no differences in clinical outcomes between groups. CONCLUSIONS One-quarter of untreated CHD patients showed a ≥2log10 decline in HDV-RNA and 20% reached HDV-RNA undetectability during a mean follow-up of 5.6 years. The decline was associated with ALT decrease. These findings have implications for designing new therapies for CHD.

Abstract
Background COVID-19 is a potentially severe disease caused by the recently described SARS-CoV-2. Whether liver fibrosis might be a relevant player in the natural history of COVID-19 is currently unknown. We aimed to evaluate the association between FIB-4 and the risk of progression to critical illness in middle-aged patients with COVID-19. Methods In this multicenter, retrospective study with prospective follow-up of 160 patients aged 35–65 years with COVID-19, FIB-4, clinical, and biochemical variables were collected at baseline. FIB-4 ≥2.67 defined patients with risk for advanced liver fibrosis. Results Risk for advanced fibrosis was estimated in 28.1% of patients. Patients with FIB-4 ≥2.67 more frequently required mechanical ventilation (37.8% vs 18.3%; P = .009). In multivariate analysis, FIB-4 ≥2.67 (odds ratio [OR], 3.41; 95% confidence interval [CI], 1.30–8.92), cardiovascular risk factors (OR, 5.05; 95% CI, 1.90–13.39), previous respiratory diseases (OR, 4.54; 95% CI, 1.36–15.10), and C-reactive protein (OR, 1.01; 95% CI, 1.01–1.02) increased significantly the risk of ICU admission. Bootstrap confirmed FIB-4 as an independent risk factor. Conclusions In middle-aged patients with COVID-19, FIB-4 may have a prognostic role. The link between liver fibrosis and the natural history of COVID-19 should be evaluated in future studies.

Abstract
A percentage of hepatitis C virus (HCV)-infected patients fail direct acting antiviral (DAA)-based treatment regimens, often because of drug resistance-associated substitutions (RAS). The aim of this study was to characterize the resistance profile of a large cohort of patients failing DAA-based treatments, and investigate the relationship between HCV subtype and failure, as an aid to optimizing management of these patients. A new, standardized HCV-RAS testing protocol based on deep sequencing was designed and applied to 220 previously subtyped samples from patients failing DAA treatment, collected in 39 Spanish hospitals. The majority had received DAA-based interferon (IFN) α-free regimens; 79% had failed sofosbuvir-containing therapy. Genomic regions encoding the nonstructural protein (NS) 3, NS5A, and NS5B (DAA target regions) were analyzed using subtype-specific primers. Viral subtype distribution was as follows: genotype (G) 1, 62.7%; G3a, 21.4%; G4d, 12.3%; G2, 1.8%; and mixed infections 1.8%. Overall, 88.6% of patients carried at least 1 RAS, and 19% carried RAS at frequencies below 20% in the mutant spectrum. There were no differences in RAS selection between treatments with and without ribavirin. Regardless of the treatment received, each HCV subtype showed specific types of RAS. Of note, no RAS were detected in the target proteins of 18.6% of patients failing treatment, and 30.4% of patients had RAS in proteins that were not targets of the inhibitors they received. HCV patients failing DAA therapy showed a high diversity of RAS. Ribavirin use did not influence the type or number of RAS at failure. The subtype-specific pattern of RAS emergence underscores the importance of accurate HCV subtyping. The frequency of "extra-target" RAS suggests the need for RAS screening in all three DAA target regions.

Abstract
BACKGROUND Antiviral treatment of patients with chronic hepatitis B (CHB) in the grey zone of treatment comands risk management in order to optimize the health outcome. In this sense, the identification of HBV mutants related with an increased risk of hepatocellular carcinoma (HCC) could be useful to identify subpopulations with potential indication of antiviral treatment.
AIM To analyze the prevalence/persistence of hepatitis B virus (HBV) preS and basal core promoter (BCP)/precore/core variants associated to HCC development in CHB patients in the grey zone.
METHODS Work was designed as a longitudinal retrospective study, including 106 plasma samples from 31 patients with CHB in the grey zone of treatment: Hepatitis B e antigen negative, HBV-DNA levels between 12-20000 IU/mL, normal or discordant transaminase levels during follow up and mild/moderate necro-inflammatory activity in liver biopsy or Fibroscan (up to 9.5 kPa). Serum HBV-DNA was tested using the Abbott Real Time HBV Assay and the BCP/precore/core and the hepatitis B surface antigen (HBsAg) coding regions were analyzed in positive samples by PCR/bulk-sequencing to identify the HCC-related HBV mutants.
RESULTS High-risk HCC related mutants were detected in 24 (77%) patients: 19 (61%) in the BCP/precore/core, and 7 (23%) in the HBsAg coding region (2 preS1 and 5 preS2 deletions). The prevalence of preS deletions was genotype-dependent: 3/5 (60%) patients with preS2 deletions and 1/2 with preS1 deletions were infected with the HBV-E genotype. Since HBV-E was the most prevalent in sub-Saharan patients, a correlation between preS deletions and ethnicity was also found: 6/8 (75%) sub-Saharan vs 1/19 (5%) Caucasian patients had preS deletions (P = 0.00016). Remarkably, this correlation was maintained in those patients infected with HBV-A, a minor genotype in sub-Saharan patients: 2/2 patients infected with HBV-A from West Africa vs 0/6 of Caucasian origin had preS deletions. The HCC related variants were the major strains and persisted over time (up to 48 mo). Patients with preS deletions had a significant higher prevalence of F2 fibrosis stage than the negatives (57% vs 10%, P = 0.0078).
CONCLUSION HBV genetic analysis of selected populations, like sub-Saharans infected with HBV-E/A genotypes, will allow identification of subpopulations with risk of HCC development due to accumulation of high-risk HBV variants, thus commanding their increased clinical surveillance.

Abstract
OBJECTIVE Recently approved direct acting antivirals provide transformative therapies for chronic hepatitis C virus (HCV) infection. The major clinical challenge remains to identify the undiagnosed patients worldwide, many of whom live in low-income and middle-income countries, where access to nucleic acid testing remains limited. The aim of this study was to develop and validate a point-of-care (PoC) assay for the qualitative detection of HCV RNA. DESIGN We developed a PoC assay for the qualitative detection of HCV RNA on the PCR Genedrive instrument. We validated the Genedrive HCV assay through a case-control study comparing results with those obtained with the Abbott RealTime HCV test. RESULTS The PoC assay identified all major HCV genotypes, with a limit of detection of 2362 IU/mL (95% CI 1966 to 2788). Using 422 patients chronically infected with HCV and 503 controls negative for anti-HCV and HCV RNA, the Genedrive HCV assay showed 98.6% sensitivity (95% CI 96.9% to 99.5%) and 100% specificity (95% CI 99.3% to 100%) to detect HCV. In addition, melting peak ratiometric analysis demonstrated proof-of-principle for semiquantification of HCV. The test was further validated in a real clinical setting in a resource-limited country. CONCLUSION We report a rapid, simple, portable and accurate PoC molecular test for HCV, with sensitivity and specificity that fulfils the recent FIND/WHO Target Product Profile for HCV decentralised testing in low-income and middle-income countries. This Genedrive HCV assay may positively impact the continuum of HCV care from screening to cure by supporting real-time treatment decisions. TRIAL REGISTRATION NUMBER NCT02992184 .

Abstract
Despite new treatments for hepatitis C virus (HCV) infection, IFNα-based regimens still have clinical relevance in special populations of patients and remain the only therapeutic option for many patients. We sought to elucidate the interplay between two relevant factors (IL28B polymorphism and T cell immune responses) involved in the outcome of this therapy in HCV-infected patients. We evaluated 38 patients infected with HCV genotype 1-17 coinfected with HIV-who were undergoing a full course of pegIFNα/RBV therapy. The interdependence and roles of T cell-mediated immune responses and IL28B rs12979860 single-nucleotide polymorphism genotype as predictors of virological response to anti-HCV treatment in patients with chronic hepatitis C were evaluated using nonparametric tests. Factors associated with rapid virological response (RVR) in univariate analysis were presence of CD4 T cell response against NS3 HCV protein, low baseline HCV-RNA, and IL28B CC genotype. Factors associated with sustained virological response (SVR) in univariate analysis were IL28B CC genotype, low baseline HCV-RNA, and presence of CD4 response against NS2. In the multivariate analysis, low baseline HCV-RNA and NS3-specific CD4 response showed a clear trend toward association with RVR (P = 0.09 and P = 0.07, respectively). Regarding SVR, IL28B CC genotype was the strongest predictor (P = 0.02), with presence of NS2-specific CD4 response showing a clear trend (P = 0.09). HCV-specific T cell response influences the outcome of pegIFNα/RBV therapy regardless of IL28B genotype. HCV-specific T cell responses (adaptive immunity) seem to influence viral clearance both in the short and long term during therapy (RVR and SVR), whereas the influence of the IL28B genotype (innate immunity) may be more relevant to the long-lasting therapeutic effect (SVR).

Abstract
BACKGROUND & AIMS Chronic hepatitis C is a leading cause of chronic liver disease, cirrhosis and hepatocellular carcinoma. DNA methylation and histone covalent modifications constitute crucial mechanisms of genomic instability in human disease, including liver fibrosis and hepatocellular carcinoma. The present work studies the consequences of HCV-induced histone modifications in early stages of infection. METHODS Human primary hepatocytes and HuH7.5 cells were transiently transfected with the core protein of hepatitis C virus (HCV) genotypes 1a, 1b, and 2a. Infectious genotype 2a HCV in culture was also used. RESULTS We show that HCV and core protein inhibit the phosphorylation of Serine 10 in histone 3. The inhibition is due to the direct interaction between HCV core and Aurora B kinase (AURKB) that results in a decrease of AURKB activity. HCV and core significantly downregulate NF-κB and COX-2 transcription, two proteins with anti-apoptotic and proliferative effects implicated in the control of the inflammatory response. AURKB depletion reduced HCV and core repression of NF-κB and COX-2 gene transcription and AURKB overexpression reversed the viral effect. AURKB abrogation increased HCV specific infectivity which was decreased when AURKB was overexpressed. CONCLUSIONS The core-mediated decrease of AURKB activity may play a role in the inflammatory pathway during the initial steps of viral infection, while ensuring HCV infectivity.

Abstract
BACKGROUND Soluble CD36 (sCD36) clusters with insulin resistance, but no evidence exists on its relationship with hepatic fat content. We determined sCD36 to assess its link to steatosis in nonalcoholic fatty liver disease (NAFLD) and chronic hepatitis C (CHC) patients. MATERIALS AND METHODS Two hundred and twenty-seven NAFLD, eighty-seven CHC, and eighty-five patients with histologically normal liver (NL) were studied. Steatosis was graded by Kleiner's histological scoring system. Serum sCD36 and hepatic CD36 expression was assessed by immunoassay and immunohistochemistry, respectively. RESULTS In NAFLD, serum sCD36 levels were significantly higher in simple steatosis than in NL (361.4 ± 286.4 vs. 173.9 ± 137.4 pg/mL, respectively; P < 0.001), but not in steatohepatitis (229.6 ± 202.5 pg/mL; P = 0.153). In CHC, serum sCD36 levels were similar regardless of the absence (428.7 ± 260.3 pg/mL) or presence of steatosis (387.2 ± 283.6 pg/mL; P = 0.173). A progressive increase in serum sCD36 values was found in NAFLD depending on the histological grade of steatosis (P < 0.001), but not in CHC (P = 0.151). Serum sCD36 concentrations were independently associated with advanced steatosis in NAFLD when adjusted by demographic and anthropometric features [odds ratio (OR), 1.001; 95% confidence interval (CI), 1.000 to 1.002; P = 0.021] and by metabolic variables (OR, 1.002; 95% CI, 1.000 to 1.003; P = 0.001). Interestingly, a significant correlation was observed between hepatic CD36 and serum sCD36 (ρ = 0.499, P < 0.001). CONCLUSIONS Increased serum sCD36 is an independent factor associated with advanced steatosis in NAFLD.

Abstract
A total of 1,220 subjects from Equatorial Guinea living in Spain (median age = 41 years; 453 male and 767 female) was examined for antibodies to human immunodeficiency virus (HIV) and Hepatitis B (HBV), C (HCV), and D (HDV) viruses. Extracted RNA and DNA from the positive samples were used to quantify viral load. The prevalence of HIV antibodies, HCV RNA, and HBV surface antigen (HBsAg) was 10.8% (N = 132), 11.6% (N = 141), and 7.9% (N = 96), respectively. The most prevalent HIV variant was CRF02_AG (38.5%; N = 40). HCV genotype 4 (60%; N = 36) and HBV genotype A3 (32%; N = 8) were the hepatitis variants most frequently found. Superinfection with HDV was seen in 20.9% (N = 24) of HBsAg carriers. A control group of 276 immigrants from other sub-Saharan countries showed similar rates of HIV and HBsAg, although no HCV cases were found. Immigrants constitute a major source of HIV and hepatitis viruses in Spain; therefore, it is important that control measures are intensified.

Abstract
BACKGROUND Direct acting antivirals (DAA) targeting the HCV serine protease and RNA polymerase have recently entered clinical development. Information about primary resistance to these compounds in HIV-HCV-coinfected patients is scarce. METHODS All individuals newly diagnosed with HIV-1 at several clinics in Madrid between 2000 and 2010 were tested for serum HCV antibody and HCV RNA. The NS3 protease and NS5B polymerase genes were sequenced in all HCV viraemic patients with genotype 1 (G1). RESULTS From 1,684 individuals newly diagnosed with HIV-1 during the 10-year study period, 141 (8.4%) were positive for serum HCV RNA. Overall, 58% were infected with G1, being 1a in 64.2% of them. Altogether, 62% of G1a and 30% of G1b harboured HCV drug-resistant changes, with the most common being prQ80K (n=9), prV55A (n=2), polC316Y/N (n=3) and polV499A (n=24). Although no primary resistance mutations were identified for HCV protease inhibitors or nucleoside analogues, mutations C316Y/N and V499A conferring resistance to some non-nucleoside analogues were found in 6% and 51% of G1 patients, respectively. CONCLUSIONS Natural DAA resistance-associated mutations are frequently seen in HIV-HCV-coinfected individuals. Changes polV499A and prQ80K seem to be natural polymorphisms and their effect on treatment outcomes warrants further examination. However, drug resistance testing in HCV drug-naive individuals coinfected with HIV currently does not seem to be warranted before using HCV protease inhibitors and nucleoside analogues. More information is needed for HCV non-nucleoside analogues.

Abstract
The efficacy of current hepatitis C therapy in HIV/HCV-coinfected patients is largely dependent on HCV genotype. The annual prevalence of HCV genotypes/subtypes and their influence on HCV clearance with antiviral treatment were examined in a dynamic cohort of HIV/HCV-coinfected patients followed up in Madrid since 2000. Patients entered the cohort at first visit and left the cohort when HCV clearance was achieved with HCV therapy or when follow-up was interrupted for any reason, including death. A total of 672 HIV/HCV-coinfected patients constituted the cohort. The mean follow-up time was 5.5 years, corresponding to 4108 patient-years. Mean age at entry was 37 years, and 73% were men and 86% were intravenous drug users. Overall distribution of HCV genotypes was as follows: 57.1% HCV-1 (1a: 29.2%, 1b: 20.4%, unknown: 7.6%), 1.3% HCV-2, 25.4% HCV-3 and 15.9% HCV-4. A total of 274 (40.8%) patients were treated with peginterferon-ribavirin, of whom 116 (42.3%) achieved HCV clearance following 1-3 courses of therapy. The proportion of HCV-1/4 rose from 71.7% in 2000 to 76.8% in 2008, whereas the proportion of HCV-2/3 fell from 28.1% in 2000 to 23.2% in 2008. The yearly prevalence increased for HCV-1 (R(2) : 0.92, b: 0.59, P < 0.001) and HCV-4 (R(2) : 0.77, b: 0.33, P < 0.005) and conversely diminished for HCV-3 (R(2) : 0.94, b: -0.82, P < 0.001). In summary, the prevalence of HCV-1 and HCV-4 has increased over the last decade in HIV/HCV-coinfected patients, whereas conversely it has declined for HCV-3, in association with the wider use of HCV therapy (41%) in this population.

Abstract
Occult hepatitis B virus (HBV) infection (OBI) is defined as the presence of HBV DNA in the liver (with or without detectable HBV DNA in serum) for individuals testing HBV surface antigen negative. Until recently, the clinical effect of OBI was unclear on the progression of liver disease; on the development of hepatocellular carcinoma; and on the risk for reactivation or transmission of HBV infection. Several studies suggest a high prevalence of OBI among patients with cryptogenic chronic liver disease, but its role in the progression to cirrhosis remains unclear. Although OBI has been well documented in human immunodeficiency virus (HIV)-positive patients, especially among those coinfected with hepatitis C virus, further studies are needed to determine its current clinical impact in HIV setting.

Abstract
BACKGROUND Universal vaccination and antiviral therapy have reduced chronic hepatitis B virus (HBV) in natives in the Western world. However, immigration from high HBV endemic areas continues to maintain a relatively stable prevalence of chronic hepatitis B in most developed countries. METHODS All foreigners attending a referral infectious diseases department in Madrid, Spain, from January 2007 to December 2008, were evaluated for serum HBV surface antigen (HBsAg). Positive cases underwent further virological characterization. RESULTS A total of 1718 foreigners were examined, of whom 1322 (77%) were sub-Saharan Africans. Serum HBsAg was positive in 121 (7%), HIV in 135 (7.9%) and hepatitis C virus antibodies in 212 (12.3%). HBV subgenotype A3, which so far had only been reported in people originating from Cameroon, was found in nearly half (14/29) of the tested specimens with detectable serum HBV-DNA. Interestingly, the lamivudine resistance mutation rtM204V was found in two Africans (6.9%), one infected with HBV-A3 and the other with HBV-E. Lack of prior exposure to antiviral therapy in these two patients was confirmed retrospectively. CONCLUSIONS Circulation of uncommon HBV variants, including strains with primary drug resistance, may follow large immigrant flows from HBV endemic regions to Western countries. Close surveillance of this population is warranted, as early diagnosis and early antiviral therapy may reduce transmission and prevent clinical complications.

Abstract
BACKGROUND Longitudinal assessment of liver fibrosis with transient elastometry (TE) in patients with chronic viral hepatitis is becoming routine clinical practice in many clinics, as this procedure is non-invasive, easy to perform and relatively inexpensive, allowing early detection of cirrhosis. Herein, we examine the incidence of cirrhosis, using TE assessment, in HIV-infected individuals with chronic hepatitis B or C receiving highly active antiretroviral therapy (HAART). METHODS A longitudinal study was performed on a cohort of HIV-infected patients with chronic hepatitis B or C who were followed since 2004 at Hospital Carlos III (Madrid, Spain) with periodic TE assessments. The primary outcome was the development of cirrhosis, defined as liver stiffness >12.5 KPa. RESULTS A total of 508 HIV-infected patients were examined, of whom 54 developed liver cirrhosis during a mean ±(SD) follow-up of 2.6 ±1.0 years (overall incidence was 41.13 cases per 1,000 person-years). The risk of developing cirrhosis was significantly higher in 297 HCV-RNA-positive patients (either untreated or non-responders to hepatitis C therapy) compared with 55 patients who had cleared HCV with therapy (odds ratio 3.73, 95% confidence interval 1.06-13.17; P=0.04). By contrast, the risk of developing cirrhosis was low and similar in 24 HIV-HBV-coinfected patients under long-term suppressive HBV therapy (mainly tenofovir disoproxil fumarate), 132 HIV-infected patients without chronic liver disease and those who had cleared HCV with therapy. CONCLUSIONS Development of liver cirrhosis in HIV-infected individuals in the HAART era is mainly associated with active HCV coinfection. The risk of developing cirrhosis is negligible in patients who cleared HCV with therapy, as well as in HIV-HBV-coinfected patients on long-term suppressive tenofovir disoproxil fumarate therapy.

Abstract
The equilibrative nucleoside transporter 1 (ENT1) is the main protein involved in ribavirin cellular uptake. Polymorphisms at the ENT1 gene may influence ribavirin activity as part of hepatitis C virus (HCV) therapy. A retrospective study was conducted in 109 human immunodeficiency virus (HIV)-infected patients who were infected with HCV genotypes 1 or 4 who had received pegylated interferon (pegIFN)-ribavirin. Single nucleotide polymorphisms (SNPs) at the ENT1 gene were examined using TaqMan 5'-nuclease assays. In the study population, allelic frequencies at rs760370 were as follows: A3 (43 [39%] of 109 patients), AG (50 [46%] of 109 patients), and GG (16 [15%] of 109 patients). Achievement of rapid virological response was more frequent in GG carriers than in AA/AG carriers (50% vs 17%, respectively; P = .007). In multivariate analysis, the GG genotype (odds ratio [OR], 15.9; 95% confidence interval [CI], 2.8-92.2; P < .002), a baseline serum HCV-RNA level <600,000 IU/mL (OR, 45.7; 95% CI, 8.7-240.5; P <.001) and a serum ribavirin trough concentration >2.5 μg/mL (OR, 4.8; 95% CI, 1.3-17.1; P < .016) were associated with rapid virological response. When 2 or more of these factors were present, positive and negative predictive values of rapid virological response were 65% and 91%, respectively. In summary, a SNP rs760370A→G at the ENT1 gene influences the chance of rapid virological response to pegIFN-ribavirin therapy in HIV-infected patients with chronic HCV infection due to HCV genotypes 1 or 4, most likely modulating intracellular ribavirin exposure within hepatocytes.

Abstract
Information on the rate and timing of hepatitis C virus (HCV) relapse after treatment with pegylated interferon plus ribavirin is scarce. Among 604 patients treated for chronic hepatitis C, the 386 who were human immunodeficiency virus (HIV) positive attained an end-of-treatment response less frequently and experienced relapse more often than did the 218 who were HIV negative. However, episodes of HCV relapse occurred before week 12 in most cases, regardless of HIV status.

Abstract
Hepatitis E virus (HEV) is an enterically transmissible RNA agent that causes self-limited acute hepatitis. Recent reports have highlighted that organ-transplant recipients may develop chronic hepatitis E and progress to cirrhosis. Similar cases could occur in HIV patients. We have investigated 50 HIV-infected individuals with CD4 counts <200 cells/mm(3) and 43 with cryptogenic hepatitis. None of them showed HEV viremia. Thus, HEV infection does not seem to be prevalent in the HIV population and accordingly universal HEV vaccination is not warranted in these patients.

Abstract
Raman spectroscopy is applied in this work to study the adsorption of poly(ethyleneimine) (PEI) on Ag nanoparticles obtained by reduction with citrate, as well as to the study of the interaction between PEI and a plasmid. The surface-enhanced Raman spectroscopy (SERS) affords important information about the interaction and orientation of the polymer on the particles. In particular we have found that this polymer interacts with the surface through their amino groups in an interaction which also involves a change in the protonation state of amino groups as well as an increase of the chain order. This interaction implies a charge-transfer effect as deduced from the strong resonant effect in Raman spectra obtained at different excitation wavelengths. The complex formed by PEI and a plasmid, obtained by encoding the HBV (hepatitis B virus) genome inside the EcoRI restriction site of pGEM vector, was also studied by SERS. The interaction between both polymers leads to a conformational change affecting both macromolecules that can be detected by Raman at different excitation wavelengths. PEI undergoes a change to a more disordered structure as well as an increase of the number of protonated amino groups. The plasmid undergoes a structural change from A-DNA structure to B-DNA, along with a change in the superhelicity resulting in a more lineal structure when the plasmid interacts with PEI.

Abstract
BACKGROUND/AIMS There are no data about the influence of handling conditions of liver biopsies on the integrity of viral RNAs. We studied the influence of the time delay between obtaining and freezing the liver biopsy on the stability of intrahepatic positive and negative hepatitis C virus RNA (HCV-RNA) strands. METHODS Liver samples from 30 anti-HCV patients were included. For each case, one portion of the liver biopsy (first sample) was immediately frozen (20-28 s), while the other section (second sample) was kept at room temperature (1-30 min) before freezing. Each experimental time point was performed in triplicate using liver samples from three different patients. Semi-quantitative analysis of the positive and negative HCV-RNA strands and of the al-antitrypsin mRNA was performed by a Tth-based reverse-transcription polymerase chain reaction. RESULTS A significant time-related decrease in both positive (r=-0.8412, p=0.001) and negative (r=-0.8539, p=0.001) HCV-RNA strand titres was found in the second liver fractions. There were no appreciable changes in RNA titres in those samples frozen after less than 3 min. The RNA titres decreased in all but two samples incubated for 4-30 min. Thus, 3/15 (20%) and 7/11 (64%) of these samples lost positive and negative HCV-RNA strands, respectively. Alpha-1-antitrypsin mRNA titres decreased significantly (r=-0.8935, p=0.01) in those samples kept at room temperature for more than 4 min. CONCLUSION Freezing of liver samples immediately after extraction is crucial to avoid false negative HCV-RNA detection results, especially for the antigenomic RNA strand.

Abstract
BACKGROUND/AIMS In this study, the inhibition of hepatitis delta virus replication mediated by trans-ribozyme and antisense probes, alone or in combination with recombinant interferon alpha-2a, has been assayed. METHODS A 60-nucleotide-long designed trans-ribozyme, which contains the catalytic core of the hammerhead ribozyme, and a 163-nucleotide-long antisense probe were directed against the same region of the viral genome in in vitro and cell culture systems. RESULTS The ribozyme activity, assayed in a chemically isolated system, resulted in the trans-cleavage of 10-20% of the 40-nucleotide-long RNA substrate. A 5-nucleotide deletion in one of the flanking arms, obtained by random mutagenesis, resulted in enhancement of the trans-cleavage activity in as many as 40-60% of the substrate molecules. The efficiency of the optimized trans-ribozyme and antisense probes against the complete viral genome was assayed in a cell culture system. The inhibitory efficacy (25%) of the trans-ribozyme is lower than that of the antisense probe (35%) or interferon at 1000 U/ml (47%). An enhancement of the interferon efficacy was achieved when it was administered in cells having a previous basal expression of ribozyme (70%) or antisense probes (83%). CONCLUSIONS These results suggest that the combination of ribozyme or antisense probes with interferon could be a promising approach to the treatment of RNA virus infections.

Abstract
BACKGROUND & AIMS No conclusive data about GB virus C (GBV-C) tropism are available. We have studied the presence of genomic and antigenomic GBV-C RNA in serum, liver, and peripheral blood cells of 56 patients with chronic hepatitis B, C, or D virus infection. METHODS Genomic and antigenomic GBV-C RNA were detected by reverse-transcription nested polymerase chain reaction. Specificity was confirmed by sequencing, by chemical modification of the RNA, and by using tagged primers. RESULTS Genomic GBV-C RNA was found in 10 of 56 (18%) of the sera. In contrast, antigenomic strand was not detected. The sequence of the amplified GBV-C RNA from 3 patients showed a 96% homology among them and from 83% to 88% with previously described isolates. Genomic GBV-C RNA was found in 7 of 7 liver samples of the patients with serum GBV-C RNA. In 6 of these 7 patients (85%), antigenomic strand was found. Genomic RNA was found in 7 of 7 of the peripheral blood cell samples of the same 7 patients. Antigenomic GBV-C RNA was not found in these cells. CONCLUSIONS These results suggest that GBV-C is a hepatotropic virus that replicates in the human liver. The data do not support a role for GBV-C in chronic liver disease.

Abstract
Long-term effects after blood or bone marrow transplantation (BMT) are emerging as an important issue, as more patients are included in BMT programmes and as this procedure becomes more successful. Long-term liver dysfunction, mainly due to chronic graft-versus-host disease or hepatitis C virus infection, is a well-known complication. Nevertheless, the diagnosis of liver disease in this patient group is sometimes difficult and, despite adequate studies, it may remain undetected. A novel hepatitis-associated virus, hepatitis G virus (HGV), has recently been identified. The virus belongs to the Flaviviridae family and is known to be parenterally transmitted, although there is no clear evidence to implicate this agent in causing acute or chronic hepatitis. We report a patient who developed mild, but persistent, abnormalities in transaminases for 2 years after an autologous BMT. HGV RNA was detected in both serum and liver. HGV RNA persisted in serum for at least 8 months. No other known hepatitis virus was found. This report provides the first direct evidence of a patient with long-term liver abnormalities after a BMT in whom the only known hepatitis virus isolated was the HGV.

Abstract
Hepatitis B and hepatitis D viral genomes were tested by nested polymerase chain reaction in the serum and liver of 69 hepatitis B surface antigen (HBsAg) negative, anti-hepatitis C virus (HCV) positive patients (47 with HCV RNA and 22 without HCV RNA). Serum hepatitis B virus (HBV) DNA-was detected in 49% of the patients with HCV-RNA and in 64% of those without HCV-RNA. Furthermore, intrahepatic HBV-DNA was found in four of five (80%) of the biopsies analysed. Delta genome was found in 72% and 73%, respectively, of the anti-HCV positive patients with or without HCV-RNA. In addition, intrahepatic delta virus genome was detected in another four liver biopsies studied. In the group of patients with HCV-RNA, the simultaneous presence of hepatitis B and D genomes was statistically higher in transfused patients than in drug addicts, or in those with an unknown infection route (P < 0.001). These results show a high percentage of B and D genomes in HBsAg negative patients with anti-HCV, irrespective of the presence or absence of the HCV genome. However, the clinical implications of this finding should be examined in future studies.

Abstract
We examined the efficacy of decreasing high doses (beginning at 18 MU/day) of interferon-alpha 2a vs. that of daily low doses (3 MU) in the treatment of chronic hepatitis delta virus infection. Patients treated with 18 MU had a somewhat higher frequency of normalization of serum ALT levels than patients treated with low doses (31% and 12%, respectively, on an intention-to-treat basis). A decrease in the percentage of hepatitis D virus RNA positivity was observed in both groups at the end of treatment. Thus, whereas in baseline samples 10 (62%) of the patients in each group were positive for hepatitis D virus RNA in serum on slot-blot hybridization, these numbers decreased to 5 (31%) and 4 (25%) patients in groups 1 and 2, respectively, at the end of therapy. However, hepatitis D virus RNA, detected by means of nested polymerase chain reaction, remained in all but two (one in each group) patients who completed the treatment. Finally, during posttreatment follow-up, hepatitis D virus RNA levels returned to baseline values, and only one patient remained negative for this marker. The beneficial effect of interferon-alpha was only transient. Only two patients (one from each treatment group) had persistently normal serum ALT levels after 18 mo of follow-up. Finally, the presence of serum hepatitis D virus RNA at the end of therapy, detected with nested polymerase chain reaction, might be a good marker for the prediction of viral replication relapse.

Abstract
Hepatitis delta virus is a defective human infectious agent which causes severe hepatic damage in hepatitis B virus-infected patients. Although prophylactic steps and the development, in certain countries, of efficient vaccination programs against hepatitis B virus have led to a diminution of the incidence rate of this disease, hepatitis D is still an important health problem. Hepatitis D infection is therefore associated with a worse clinical evolution than hepatitis B infection alone. On the other hand, the different therapeutic strategies being assayed at present including the use of interferon, have shown to be inefficient in the treatment of this disease. In this article, different aspects of the molecular biology and natural history of the infection, specially focused on those unknown aspects of this virus, are discussed. Finally, we have included a revision of the current state of hepatitis D treatment, as well as a comment of the new experimental strategies, like the use of antisense probes and trans-ribozyme activities.

Abstract
The use of genetic amplification of the hepatitis delta virus (HDV) genome reveals the existence of different HDV replicative behaviours during the natural history of chronic HDV infection. While some of the patients (8/19, 42%) presented high and long-term maintained levels of HDV replication, as detected by slot-blot hybridization, others showed fluctuations from positive to negative, and in 5/7 (71%) polymerase chain reaction (PCR) demonstrated the presence of the HDV genome. Finally, 4 patients were persistently slot-blot-negative and in 3 of them HDV-RNA was detected by PCR in all samples tested. The correlation observed between the low levels of HDV replication and the ALT values, as well as the reactivation observed in one of the patients, suggests that PCR is useful in the virological surveillance of HDV infection, and indicates its usefulness in evaluating the effectiveness of antiviral therapy for chronic hepatitis D.

Abstract
Hepatitis delta virus (HDV) RNA detection was carried out, using a full-length HDV RNA probe, in serum of 43 patients with chronic HDV infection. Among them, 30 cases (70%) were HDV RNA-positive. With respect to other HDV markers, serum HDAg (detected by immunoblot) was found in 33 patients (77%) and IgM anti-HD in 29 (67%). A similar percentage of HDV RNA-positive patients with and without circulating hepatitis B virus (HBV) DNA (32.5 vs. 37%, respectively) was found. Antibodies against the human immunodeficiency virus (HIV) were detected in 15/43 subjects studied. The presence of HDV RNA was significantly higher (p less than 0.05) in anti-HIV-seropositive cases (93%) than in the HIV-seronegative ones (57%). Moreover, simultaneous HDV and HBV replication was found more frequently (60 vs. 18%, p less than 0.05) and at higher levels among the anti-HIV-positive patients than in the rest. In addition, in most of the anti-HIV-positive subjects, HDV RNA and HBV DNA were constantly positive during a whole year of follow-up.

Abstract
In this paper, we studied the usefulness of polymerase chain reaction (PCR) in HDV-RNA detection. Using serial dilutions of serum samples of known concentrations of HDV-RNA, PCR was 10,000-times more sensitive than slot-blot hybridization. PCR was used for the detection of HDV-RNA in 33 serum samples negative to HDV-RNA by conventional slot-blot hybridization. HDV-RNA was detected in 18/33 (54%) of the samples included in this study using PCR. When positivity to a viral genome was related to other viral replication markers, it was found that among the 18 patients positive to the viral genome, 13 (72%) had hepatitis delta antigen in the liver, and five (28%) were negative. In conclusion, HDV-RNA detection by gene amplification is 10,000-times more sensitive than slot-blot hybridization, and allows the detection of viral replication in patients without other viral replication markers.
