Background & Aims: Clinically significant portal hypertension (CSPH), defined as a hepatic venous pressure gradient (HVPG) >= 10 mmHg, persists 24 weeks after sustained virological response (SVR) in up to 78% of patients with HCV-related cirrhosis treated with direct-acting antivirals. These patients remain at risk of decompensation. However, long-term paired clinical and hemodynamic data are not available for this population. Methods: We conducted a prospective multicenter study in 226 patients with HCV-related cirrhosis and CSPH who achieved SVR after antiviral therapy. Patients with CSPH 24 weeks after end of treatment (SVR24) were offered another hemodynamic assessment 96 weeks after end of treatment (SVR96). Results: All patients were clinically evaluated. Out of 176 patients with CSPH at SVR24, 117 (66%) underwent an HVPG measurement at SVR96. At SVR96, 55/117 (47%) patients had HVPG = 16 mmHg) diminished from 41% to 15%. Liver stiffness decreased markedly after SVR (median decrease 10.5 +/- 13 kPa) but did not correlate with HVPG changes (30% of patients with liver stiffness measurement = 16 mmHg and history of ascites. Conclusions: Patients achieving SVR experienced a progressive reduction in portal pressure during follow-up. However, CSPH may persist in up to 53-65% of patients at SVR96, indicating persistent risk of decompensation. History of ascites and high-risk HVPG values identified patients at higher risk of de novo or further clinical decompensation. Lay summary: As a major complication of cirrhosis, clinically significant portal hypertension (CSPH) is associated with adverse clinical outcomes. Herein, we show that CSPH persists at 96 weeks in just over half of patients with HCV-related cirrhosis, despite HCV elimination by direct-acting antivirals. Despite viral cure, patients with CSPH at the start of antiviral treatment remain at long-term risk of hepatic complications and should be managed accordingly.

Background & Aims The interferon-free regimen paritaprevir/ritonavir, ombitasvir + dasabuvir (PTV/r/OBV/DSV) has shown high efficacy in patients with hepatitis C virus (HCV) genotype 1b infection when administered for 8 or 12 weeks, but data regarding the 8-week treatment are scarce. The aim of our study was to assess the efficacy and safety of the 8-week administration of PTV/r/OBV/DSV in a real-world cohort. Methods We performed a multicentre observational study from Spanish Hepa-C database including patients receiving 8 weeks of PTV/r/OBV/DSV (October 2016-November 2017). Those with advanced fibrosis, with non-genotype 1b or who were treatment-experienced were excluded. Results A total of 211 patients were registered from 23 Spanish centres; eleven were excluded. At baseline, 42.5% (n = 85) were male, median (range) age was 57 (23-86), ALT was 45 (11-494) IU/mL, viral load was 6.1 (3.3-8.2) log10 IU/mL, and 74.5% had mild liver fibrosis (F0-F1) and 25.5% moderate fibrosis (F2). At the end of treatment (EOT), HCV viral load was undetectable in 100% (200/200). Seven patients relapsed after treatment discontinuation. Sustained virological response (SVR12) rates by intention-to-treat analysis were 96% (192/200). Regarding treatment safety, 2 patients developed ALT elevation >5x ULN, but there were no treatment discontinuations. One patient died 7 weeks after EOT. Conclusion Treatment with PTV/r/OBV/DSV in genotype 1b-infected treatment-naive patients with mild-moderate fibrosis shows excellent efficacy and safety in real life, similarly to clinical trials.

Patients admitted with acute variceal bleeding (AVB) and Child-Pugh C score (CP-C) or Child-Pugh B plus active bleeding at endoscopy (CP-B+AB) are at high risk for treatment failure, rebleeding, and mortality. A preemptive transjugular intrahepatic portosystemic shunt (p-TIPS) has been shown to improve survival in these patients, but its use in clinical practice has been challenged and not routinely incorporated. The present study aimed to further validate the role of preemptive TIPS in a large number of high-risk patients. This multicenter, international, observational study included 671 patients from 34 centers admitted for AVB and high risk of treatment failure. Patients were managed according to current guidelines, and use of drugs and endoscopic therapy (D+E) or p-TIPS was based on individual center policy. p-TIPS in the setting of AVB is associated with a lower mortality in CP-C patients compared with D+E (1 year mortality 22% vs. 47% in D+E group; P = 0.002). Mortality rate in CP-B+AB patients was low, and p-TIPS did not improve it. In CP-C and CP-B+AB patients, p-TIPS reduced treatment failure and rebleeding (1-year cumulative incidence function probability of remaining free of the composite endpoint: 92% vs. 74% in the D+E group; P = 0.017) and development of de novo or worsening of previous ascites without increasing rates of hepatic encephalopathy. Conclusion: p-TIPS must be the treatment of choice in CP-C patients with AVB. Because of the strong benefit in preventing further bleeding and ascites, p-TIPS could be a good treatment strategy for CP-B+AB patients. ispartof: HEPATOLOGY vol:69 issue:1 pages:282-293 ispartof: location:United States status: published

Background Clinical decompensation of cirrhosis is associated with poor prognosis. Clinically significant portal hypertension (CSPH), defined by a hepatic venous pressure gradient (HVPG) >= 10 mm Hg, is the strongest predictor of decompensation. This study aimed at assessing whether lowering HVPG with beta blockers could decrease the risk of decompensation or death in compensated cirrhosis with CSPH. Methods This study on beta blockers to prevent decompensation of cirrhosis with portal hypertension (PREDESCI) was an investigator-initiated, double-blind, randomised controlled trial done in eight hospitals in Spain. We enrolled patients with compensated cirrhosis and CSPH without high-risk varices. All participants had HVPG measurements with assessment of acute HVPG-response to intravenous propranolol. Responders (HVPG-decrease >= 10%) were randomly assigned to propranolol (up to 160 mg twice a day) versus placebo and non-responders to carvedilol (

BACKGROUND & AIMS: In phase 3 trials and real-world settings, smaller proportions of patients with genotype 3 hepatitis C virus (HCV) infection and cirrhosis have a sustained virologic response 12 weeks after treatment (SVR12) with the combination of sofosbuvir and velpatasvir than in patients without cirrhosis. It is unclear whether adding ribavirin to this treatment regimen increases SVRs in patients with genotype 3 HCV infection and cirrhosis. METHODS: We performed a phase 2 trial of 204 patients with genotype 3 HCV infection and compensated cirrhosis (mean age 51 +/- 7.4 years) at 29 sites in Spain from August 19, 2016 through April 18, 2017. Patients were assigned to groups given sofosbuvir and velpatasvir for 12 weeks (n = 101) or sofosbuvir and velpatasvir plus ribavirin for 12 weeks (n = 103). The primary efficacy end point was SVR12. RESULTS: The overall rates of SVR12 were 91% (92 of 101; 95% CI 84-96) for the sofosbuvir-velpatasvir group and 96% (99 of 103; 95% CI 90-99) for the sofosbuvir-velpatasvir plus ribavirin group. In the sofosbuvir-velpatasvir group, a smaller proportion of patients with baseline resistance-associated substitutions (RASs) in nonstructural protein 5A (NS5A) achieved an SVR12 (84%) than did patients without (96%). In the sofosbuvir-velpatasvir plus ribavirin group, baseline RASs had less effect on the proportion of patients with an SVR12 (96% for patients with baseline RASs; 99% for patients without). The most common adverse events (which occurred in >= 10% of patients) were asthenia (12%) in the sofosbuvir-velpatasvir group and asthenia (27%), headache (24%), and insomnia (12%) in the sofosbuvir-velpatasvir plus ribavirin group. CONCLUSIONS: Consistent with findings from previous studies, a high rate of patients (91% and 96%) with genotype 3 HCV infection and compensated cirrhosis achieved an SVR12 with sofosbuvir and velpatasvir, with or without ribavirin. Of patients treated with sofosbuvir and velpatasvir without ribavirin, fewer patients with baseline NS5A RASs achieved an SVR12 compared with patients without baseline NS5A.

ObjectiveTo evaluate the safety, tolerability and efficacy of a probiotic supplementation for Helicobacter pylori (H.pylori) eradication therapy. DesignConsecutive adult naive patients with a diagnosis of H.pylori infection who were prescribed eradication therapy according to clinical practice (10-day triple or nonbismuth quadruple concomitant therapy) randomly received probiotics (1x10(9) colony-forming units each strain, Lactobacillus plantarum and Pediococcus acidilactici) or matching placebo. Side effects at the end of the treatment, measured through a modified De Boer Scale, were the primary outcome. Secondary outcomes were compliance with therapy and eradication rates. ResultsA total of 209 patients (33% triple therapy, 66% non-bismuth quadruple therapy) were included [placebo (n=106) or probiotic (n=103)]. No differences were observed regarding side effects at the end of the treatment between groups ( -0.023, P 0.738). Female gender (P90% in all cases) between triple and quadruple concomitant therapy. ConclusionProbiotic supplementation containing Lactobacillus Plantarum and Pediococcus acidilactici to H.pylori treatment neither decreased side effects nor improved compliance with therapy or eradication rates.

OBJECTIVES: Interferon-free therapies have an improved safety and efficacy profile. However, data in elderly patients, who have frequently advanced liver disease, associated comorbidities, and use concomitant medications are scarce. The im of this study was to assess the effectiveness and tolerability of all-oral regimens in elderly patients in real-life clinical practice. METHODS: Retrospective analysis of hepatitis C virus (HCV) patients aged >= 65 years receiving interferon-free regimens within the Spanish National Registry (Hepa-C). RESULTS: Data of 1,252 patients were recorded. Of these, 955 (76%) were aged 65-74 years, 211 (17%) were aged 75-79 years, and 86 (7%) were aged >= 80 years at the start of antiviral therapy. HCV genotype-1b was predominant (88%) and 48% were previous non-responders. A significant proportion of patients had cirrhosis (922; 74%), of whom 11% presented decompensated liver disease. The most used regimens were SOF/LDV (33%), 3D (28%), and SOF/SMV (26%). Ribavirin was added in 49% of patients. Overall, the sustained virological response (SVR12) rate was 94% without differences among the three age categories. Albumin = 75 years (2.59 (1.16-5.83); P = 0.02) and albumin = 75 years) or those with advanced liver disease (albumin

Background & Aims: Clinical trials evaluating second-generation direct-acting antiviral agents (DAAs) have shown excellent rates of sustained virologic response (SVR) and good safety profiles in patients with chronic hepatitis C virus (HCV) genotype 1 infection. We aimed to investigate the effectiveness and safety of two oral DAA combination regimens, ombitasvir/paritaprevir/rito navir plus dasabuvir (OMV/PTV/r + DSV) and ledipasvir/sofosbuvir (LDV/SOF), in a real-world clinical practice. Methods: Data from HCV genotype 1 patients treated with either OMV/PTV/r + DSV +/- ribavirin (RBV) (n = 1567) or LDV/SOF +/- RBV (n = 1758) in 35 centers across Spain between April 1, 2015 and February 28, 2016 were recorded in a large national database. Demographic, clinical and virological data were analyzed. Details of serious adverse events (SAEs) were recorded. Results: The two cohorts were not matched with respect to baseline characteristics and could not be compared directly. The SVR12 rate was 96.8% with OMV/PTVr/DSV +/- RBV and 95.8% with LDV/SOF +/- RBV. No significant differences were observed in SVR according to HCV subgenotype (p = 0.321 [OMV/PTV/r + DSV +/- RBV] and p = 0.174 [LDV/SOF]) or degree of fibrosis (c0.548 [OMV/PTV/r/DSV +/- RBV] and p = 0.085 [LDV/SOF]). Only baseline albumin level was significantly associated with failure to achieve SVR (p < 0.05) on multivariate analysis. Rates of SAEs and SAE-associated treatment discontinuation were 5.4% and 1.7%, in the OMV/PTV/r + DSV subcohort and 5.5% and 1.5% in the LDV/SOF subcohort, respectively. Hepatocellular carcinoma (HCC) recurred in 30% of patients with a complete response to therapy for previous HCC. Incident HCC was reported in 0.93%. Conclusions: In this large cohort of patients managed in the real-world setting in Spain, OMV/PTV/r + DSV and LDV/SOF achieved high rates of SVR12, comparable to those observed in randomized controlled trials, with similarly good safety profiles. Lay summary: In clinical trials, second-generation direct-acting antiviral agents (DAAs) have been shown to cure over 90% of patients chronically infected with the genotype 1 hepatitis C virus and have been better tolerated than previous treatment regimens. However, patients enrolled in clinical trials do not reflect the real patient population encountered in routine practice. The current study, which includes almost 4,000 patients, demonstrates comparable rates of cure with two increasingly used DAA combinations as those observed in the clinical trial environment, confirming that clinical trial findings with DAAs translate into the real-world setting, where patient populations are more diverse and complex.

Patients with hepatitis C virus (HCV) genotype 4 infection are poorly represented in clinical trials of second-generation direct-acting antiviral agents (DAAs). More data are needed to help guide treatment decisions. We investigated the effectiveness and safety of DAAs in patients with genotype 4 infection in routine practice. In this cohort study, HCV genotype 4-infected patients treated with ombitasvir/paritaprevir/ritonavir (OMV/PTVr) + ribavirin (RBV) (n=122) or ledipasvir/sofosbuvir (LDV/SOF) +/- RBV (n=130) included in a national database were identified and prospectively followed up. Demographic, clinical and virologic data and serious adverse events (SAEs) were analyzed. Differences between treatment groups mean that data cannot be compared directly. Overall sustained virologic response at Week 12 post treatment (SVR12) was 96.2% with OMV/PTVr+RBV and 95.4% with LDV/SOF +/- RBV. In cirrhotic patients, SVR12 was 91.2% with OMV/PTVr+RBV and 93.2% with LDV/SOF +/- RBV. There was no significant difference in SVR12 according to degree of fibrosis in either treatment group (P = .243 and P = .244, respectively). On multivariate analysis, baseline albumin 2 mg/dL (both cohorts) were significantly associated with failure to achieve SVR (P < .05). Rates of SAEs and SAE-associated discontinuation were 5.7% and 2.5%, respectively, in the OMV/PTVr subcohort and 4.6% and 0.8%, respectively, in the LDV/SOF subcohort. DAA-based regimens returned high rates of SVR12, comparable to limited data from clinical trials, in cirrhotic and non-cirrhotic HCV genotype 4 patients managed in a realworld setting. Safety profiles of both regimens were good and comparable to those reported for other HCV genotypes.

Background & Aims: The development of direct-acting antiviral agents (DAAs) is a major step forward in the treatment of hepatitis C (HCV). The aims of the study were to evaluate the efficacy and tolerability of DAAs in kidney transplant (KT) recipients. Methods: Hepa-C is a Spanish registry of patients treated with DAAs in which clinical, virological and analytical data were prospectively included. We report on the data from 103 KT recipients who received DAAs. Results: The most commonly used DAAs combinations were sofosbuvir/ledipasvir (n = 59, 57%) and sofosbuvir + daclatasvir (n = 18, 17%). Ribavirin was used in 41% of patients. Sustained viral response after 12 weeks (SVR12) rate was 98%. Grade 2 or 3 anemia appeared in 14 (33%) of patients receiving ribavirin and in 9 (15%) without (p = 0.03). There were three episodes of acute humoral graft rejection. No patient discontinued therapy due to adverse events. Importantly, 57 (55%) patients required immunosuppression dose adjustment. Overall, there were no statistically significant differences in the mean level of serum creatinine, eGFR and proteinuria before and after treatment. Nonetheless, seventeen (16%) patients experienced renal dysfunction (increase in serum creatinine >25%) during antiviral therapy, of whom 65% were cirrhotic in comparison with only 29% cirrhotic patients who did not develop significant renal dysfunction (p = 0.004). Conclusions: Antiviral therapy with DAAs was highly efficacious and safe in KT recipients. Nevertheless, a non-negligible number of patients, most of them cirrhotic, developed mild allograft dys-function and a significant proportion of patients required immunosuppression dose adjustment, warranting a close follow-up during therapy. Lay summary: Infection by hepatitis C virus is often found in kidney transplant patients and its presence increases mortality and graft failure. We investigated the efficacy and safety of the new direct-acting hepatitis C antivirals in this population, in which previous information is scarce. Our data shows that, as occurs in the non-transplant setting, new anti-HCV antivirals are highly efficacious kidney transplant patients. Overall, this therapy is also quite safe, although worsening of renal function is observed in 16% of patients warranting a close follow-up observation of graft function during antiviral therapy.

Over the last 5 years, therapies for hepatitis C virus (HCV) infection have improved significantly, achieving sustained virologic response (SVR) rates of up to 100% in clinical trials in patients with HCV genotype 1. We investigated the effectiveness and safety of ombitasvir/paritaprevir/ritonavir +/- dasabuvir in an early access programme. This was a retrospective, multicentre, national study that included 291 treatment-naive and treatment-experienced patients with genotype 1 or 4 HCV infection. Most patients (65.3%) were male, and the mean age was 57.5years. The mean baseline viral load was 6.1 log, 69.8% had HCV 1b genotype, 72.9% had cirrhosis and 34.7% were treatment-naive. SVR at 12 weeks posttreatment was 96.2%. Four patients had virological failure (1.4%), one leading to discontinuation. There were no statistical differences in virological response according to genotype or liver fibrosis. Thirty patients experienced serious adverse events (SAEs) (10.3%), leading to discontinuation in six cases. Hepatic decompensation was observed in five patients. Four patients died during treatment or follow-up, three of them directly related to liver failure. Multivariate analyses showed a decreased probability of achieving SVR associated with baseline albumin, bilirubin and Child-Pugh score B, and a greater probability of developing SAEs related to age and albumin. This combined therapy was highly effective in clinical practice with an acceptable safety profile and low rates of treatment discontinuation.

BACKGROUND & AIMS: The combination of beta-blockers and band ligation is the standard approach to prevent variceal rebleeding, but bleeding recurs and mortality is high. The lipid-lowering drug simvastatin decreases portal pressure, improves hepatocellular function, and might reduce liver fibrosis. We assessed whether adding simvastatin to standard therapy could reduce rebleeding and death after variceal bleeding in patients with cirrhosis. METHODS: We performed a multicenter, double-blind, parallel trial of 158 patients with cirrhosis receiving standard prophylaxis to prevent rebleeding (a beta-blocker and band ligation) in Spain from October 2010 through October 2013. Within 10 days of bleeding, subjects were randomly assigned, but stratified by Child-Pugh class of A or B vs C, to groups given simvastatin (20 mg/d the first 15 days, 40 mg/d thereafter; n = 69) or placebo (n = 78). Patients were followed for as long as 24 months. The primary end point was a composite of rebleeding and death, and main secondary end points were the individual components of the composite (death and rebleeding). RESULTS: The primary end point was met by 30 of 78 patients in the placebo group and 22 of 69 in the simvastatin group (P = .423). Seventeen patients in the placebo group died (22%) vs 6 patients in the simvastatin group (9%) (hazard ratio for adding simvastatin to therapy = 0.39; 95% confidence interval: 0.15-0.99; P = .030). Simvastatin did not increase survival of patients with Child-Pugh class C cirrhosis. Rebleeding occurred in 28% of patients in the placebo group and 25% in the simvastatin group (P = .583). Serious adverse events occurred in 53% of patients in the placebo group and 49% in the simvastatin group (P = .752); the percentages of serious adverse events related to therapy were 11% in the placebo group vs 8% in the in the simvastatin group (P = .599). Two patients in the simvastatin group, each with advanced liver disease, developed rhabdomyolysis. CONCLUSIONS: In a randomized controlled trial, addition of simvastatin to standard therapy did not reduce rebleeding, but was associated with a survival benefit for patients with Child-Pugh class A or B cirrhosis. Survival was not the primary end point of the study, so these results require validation. The incidence of rhabdomyolysis in patients receiving 40 mg/d simvastatin was higher than expected.

Introduction: Most discontinuations due to lack of virological response occur during the first few weeks of hepatitis c virus (HCV) triple therapy. Improved knowledge of baseline factors and their correlation with boceprevir decision points may predict treatment success. Methods: An observational, retrospective study was conducted to describe the lead-in period as a clinical decision tool in HCV genotype 1 patients treated with boceprevir. Data were collected from the medical records of 186 consecutive patients distributed across 20 Spanish general hospitals. Results: This study included 171 patients. A total of 80% had fibrosis F3/F4, 74% were previously treated, and 26% were treatment-naive. After the lead-in period, 54.5% of the patients had a reduction of >= 1 log(10); this reduction occurred in 52.5% of those with advanced fibrosis. Boceprevir therapy was started in 94% of the patients. Discontinuations at week 4 were limited to null responders with cirrhosis. The baseline factors associated with virological response at week 4 were IL28B, previous response, and fibrosis score. At week 8, HCV-RNA was undetectable in 48.8% of the patients. The correlation between responses at weeks 8 and 12 was 88%. Conclusion: In the Spanish clinical setting, lead-in was mainly used as a clinical decision point for non-responders with cirrhosis. The good correlation between stopping rules at weeks 8 and 12 could be used to anticipate discontinuation, thus saving adverse events and costs. (C) 2015 Elsevier Espana, S.L.U. and AEEH y AEG.

BACKGROUND: Helicobacter pylori is associated with benign and malignant diseases of the upper gastrointestinal tract, and increasing antibiotic resistance has made alternative treatments necessary. Our aim was to assess the efficacy and safety of a new, single-capsule treatment versus the gold standard for H pylori eradication. METHODS: We did a randomised, open-label, non-inferiority, phase 3 trial in 39 sites in Europe, comparing the efficacy and safety of 10 days of quadruple therapy with omeprazole plus a single three-in-one capsule containing bismuth subcitrate potassium, metronidazole, and tetracycline (quadruple therapy) versus 7 days of omeprazole, amoxicillin, and clarithromycin (standard therapy) in adults with recorded H pylori infection. Patients were randomly assigned treatment according to a predetermined list independently generated by Quintiles Canada (Ville St-Laurent, QC, Canada). Our study was designed as a non-inferiority trial but was powered to detect superiority. Our primary outcome was H pylori eradication, established by two negative (13)C urea breath tests at a minimum of 28 and 56 days after the end of treatment. Our assessment for non-inferiority was in the per-protocol population, with subsequent assessment for superiority in the intention-to-treat population (ie, all participants randomly assigned treatment). This study is registered with ClinicalTrials.gov, number NCT00669955. FINDINGS: 12 participants were lost to follow-up and 101 were excluded from the per-protocol analysis. In the per-protocol population (n=339), the lower bound of the CI for treatment with quadruple therapy was greater than the pre-established non-inferiority margin of -10% (95% CI 15·1-32·3; p

Mericitabine is a nucleoside analog polymerase inhibitor of hepatitis C virus (HCV). Treatment-naive HCV genotype 1 or 4 patients were randomized to double-blind treatment with oral mericitabine at a dosage of 500 mg twice-daily (BID) for 12 weeks (A), 1,000 mg BID for 8 (B) or 12 weeks (C and D), or placebo BID for 12 weeks (E). All patients received pegylated interferon alpha-2a (Peg-IFNα-2a; 40 kD)/ribavirin (RBV) at standard doses for 24 or 48 weeks during and after mericitabine/placebo therapy. Patients in arms A-C who maintained a virologic response (VR) (HCV RNA

The addition of protease inhibitors, boceprevir or telaprevir, to peginterferon+ribavirin (PegIFN/RBV) increases the frequency as well as the severity, and hence, clinical relevance of anemia, which has now become one of the major complications associated with triple therapy. Most significant factors associated with anemia in patients receiving triple therapy include older age, lower body mass index (BMI), advanced fibrosis, and lower baseline hemoglobin. The variability in inosine triphosphate pyrophosphatase (ITPA) gene, which encodes a protein that hydrolyses inosine triphosphate (ITP), has been identified as an essential genetic factor for anemia both in dual and triple therapy. The correct management of anemia is based on anticipation, characterization and therapeutic management. Basically, anemia can be characterized in 3 types: ferropenic (mostly in fertile women), thalassemic type hemolytic anemia, and anemia from chronic processes. Functional deficit of iron should also be excluded in patients with normal ferritin and lower saturation of transferrin. Ribavirin dose reduction and epoetin, sequentially, are indicated in the management of anemia. Epoetin non-response can be caused by lack of time, type of anemia, functional iron deficit or erythropoietin resistance. In the transplantation setting, adding a protease inhibitor to PegIFN/RBV results in a significant increase in the incidence and severity of anemia and, as a consequence, a greater need for epoetin, transfusions, and ribavirin dose reductions. Packed red cell transfusions are utilized when hemoglobin decreases to less than 7.5g/dl and/or there are clinical symptoms and/or there is no response to other therapeutic measures.

Chronic viral hepatitis infection affects an estimated 325 million people globally. People who initiate treatment after significant disease progression face increased risk of severe liver complications and death. Data are scarce on the characteristics and risk factors of people who present late to care in Spain and globally. Data were collected from January 2018 to December 2019 to report late presentation (LP) to specialist care at 11 large university hospitals in Spain to assess related risk factors using a multivariable logistic regression model. 2290 (CHB = 505, CHC = 1785) patients were analysed, with 581 (25.2%) presenting late. Hepatitis C patients more frequently reported LP compared to hepatitis B patients (28.1% vs 15.0%; p, AP, TMW, JVL acknowledge support to ISGlobal from the Spanish Ministry of Science, Innovation and Universities through the “Centro de Excelencia Severo Ochoa 2019–2023” Programme (CEX2018-000806-S), and support from the Government of Catalonia through the CERCA Programme.

[Background & Aims] Non-alcoholic fatty liver disease (NAFLD) has become a major public health problem, but the prevalence of fibrosis associated with non-alcoholic steatohepatitis (NASH) is largely unknown in the general population. This study aimed to provide an updated estimation of the prevalence of NASH fibrosis in Spain., [Methods] This was an observational, retrospective, cross-sectional, population-based study with merged data from two Spanish datasets: a large (N = 12 246) population-based cohort (ETHON), including transient elastography (TE) data, and a contemporary multi-centric biopsy-proven NASH cohort with paired TE data from tertiary centres (N = 501). Prevalence for each NASH fibrosis stage was estimated by crossing TE data from ETHON dataset with histology data from the biopsy-proven cohort., [Results] From the patients with valid TE in ETHON dataset (N = 11 440), 5.61% (95% confidence interval [95% CI]: 2.53-11.97) had a liver stiffness measurement (LSM) ≥ 8 kPa. The proportion attributable to NAFLD (using clinical variables and Controlled Attenuation Parameter) was 57.3% and thus, the estimated prevalence of population with LSM ≥ 8 kPa because of NAFLD was 3.21% (95% CI 1.13–8.75). In the biopsy-proven NASH cohort, 389 patients had LSM ≥ 8 kPa. Among these, 37% did not have significant fibrosis (F2-4). The estimated prevalence of NASH F2-3 and cirrhosis in Spain's adult population were 1.33% (95% CI 0.29–5.98) and 0.70% (95% CI 0.10–4.95) respectively., [Conclusions] These estimations provide an accurate picture of the current prevalence of NASH-related fibrosis in Spain and can serve as reference point for dimensioning the therapeutic efforts that will be required as NASH therapies become available., JC is a receptor of a grant of Fondo Investigaciones Sanitarias (FIS): PI18/01304.

Este documento refleja la posición de la AEEH respecto a la eliminación del virus de la hepatitis C (VHC), estableciendo una amplia serie de recomendaciones que se pueden agrupar en cinco categorías: 1) cribado del VHC en función de la edad, de la existencia de factores de riesgo clásicos de adquisición de la infección, búsqueda activa de pacientes diagnosticados con anterioridad y desarrollo de estrategias de microeliminación en poblaciones vulnerables; 2) simplificación del diagnóstico del VHC (diagnóstico en un solo paso y diagnóstico en el punto de atención del paciente); 3) simplificación del tratamiento de los pacientes y mejora de los circuitos asistenciales; 4) medidas de política sanitaria, y, finalmente, 5) establecimiento de indicadores de eliminación del VHC. The Spanish Association for the Study of the Liver (AEEH) is convinced that the elimination of hepatitis C virus (HCV) in Spain is possible as long as we are able to use the resources and tools necessary for it. This document reflects the position of the AEEH regarding the elimination of HCV, establishing a wide range of recommendations that can be grouped into five categories: 1) Screening of HCV according to age, of the existence of classic acquisition risk factors of infection, active search of previously diagnosed patients and development of microelimination strategies in vulnerable populations; 2) Simplification of HCV diagnosis (onestep diagnosis and diagnosis at the point of patient care); 3) Simplification of patient treatment and improvement of care circuits; 4) Health policy measures, and, finally, 5) Establishment of HCV elimination indicators.

There is a need, in NAFLD management, to develop non-invasive methods to detect steatohepatitis (NASH) and to predict advanced fibrosis stages. We evaluated a tool based on optical analysis of liver magnetic resonance images (MRI) as biomarkers for NASH and fibrosis detection by investigating patients with biopsy-proven NAFLD who underwent magnetic resonance (MR) protocols using 1.5T General Electric (GE) or Philips devices. Two imaging biomarkers (NASHMRI and FibroMRI) were developed, standardised and validated using area under the receiver operating characteristic curve (AUROC) analysis. The results indicated NASHMRI diagnostic accuracy for steatohepatitis detection was 0.83 (95% CI: 0.73–0.93) and FibroMRI diagnostic accuracy for significant fibrosis determination was 0.85 (95% CI: 0.77–0.94). These findings were independent of the MR system used. We conclude that optical analysis of MRI has high potential to define non-invasive imaging biomarkers for the detection of steatohepatitis (NASHMRI) and the prediction of significant fibrosis (FibroMRI) in NAFLD patients., The research leading to these results has received funding from the European Community’s Seventh Framework Programme (FP7/2007–2013) under grant agreement #HEALTH-F2-2009-241762 for the project Fatty Liver Inhibition of Progression (FLIP) and from Consejería de Salud de la Junta de Andalucía under grant agreement #PI-0488-2012/2012. Imaging biomarkers (NASHMRI and FibroMRI) are protected by a European patent #EP15382118.

Background and Aims: To maximize cost/efficay of boceprevirbased triple therapy (BOC) in patients with HCV-related advanced fibrosis/cirrhosis. Methods: ITT SVR12, safety and futility rules value were evaluated in the multicenter national Italian and Spanish early access Name- Patient-Program which includes treatment-experienced patients with HCVG1-related advanced fibrosis/cirrhosis (Metavir F3/4) treated with BOC in both countries. Results: 402 patients (mean age 55 years; range 22–75), 316 (78.6%) G1b, 255 (63.4%) F4, 60 (30.9%) with oesophageal varices, 137 (34.1%) relapsers, 95 (23.6%) partial and 168 (41.8%) null responders were enrolled.
