Significant human and material resources have been diverted to coronavirus disease 2019 (COVID-19). Healthcare workers are at high risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We assess the impact of the COVID-19 pandemic on gastroenterology and hepatology departments and specialists in Spain.This study involves a nationwide survey addressing the impact of COVID-19 on resources, procedures, and physicians of gastroenterology and hepatology departments in 81 hospitals representative of the Spanish National Health Service.Overall, 41.8% of hospital beds and 40.7% of gastroenterology and hepatology beds were allocated to COVID-19 patient care, as well as 24.8% of gastroenterologists and 58.3% of residents. Outpatient visits, abdominal ultrasounds, and endoscopies were reduced by 81.8-91.9%. Nine large university hospitals had 75% and 89% reductions in therapeutic endoscopies and hepatocellular carcinoma surgery, respectively, with cancelation of elective liver transplant and transjugular intrahepatic portosystemic shunt. Prevalence of infected physicians was 10.6% and was dependent on regional population incidence (r = 0.74, P = 0.001), with 11% hospitalized and one physician dying. Up to 63.4% of physicians may have been infected before or shortly after Spain entered lockdown, 57% of them having recently performed endoscopies. Adequate protection was acknowledged in 80% hospitals, but only 2.9% performed regular SARS-CoV-2 testing.The impact of the COVID-19 pandemic on healthcare delivery has been massive. A wave of gastroenterology-related complications is expected because of resource diversion. Gastroenterologists have a high prevalence of infection, although they may have been infected during a first phase of lower awareness and protection. Regular SARS-CoV-2 screening, adequate protection, and quick reorganization of healthcare resources are still needed.

The global pandemic of coronavirus disease‐2019 (COVID‐19) has led to significant disruptions in healthcare delivery. Patients with chronic liver diseases require a high level of care and are therefore particularly vulnerable to disruptions in medical services during COVID‐19. Recent data have also identified chronic liver disease as an independent risk factor for COVID‐19 related hospital mortality. In response to the pandemic, national and international societies have recommended interim changes to the management of patients with liver diseases. These modifications included the implementation of telehealth, postponement or cancelation of elective procedures, and other non‐urgent patient care‐related activities. There is concern that reduced access to diagnosis and treatment can also lead to increased morbidity in patients with liver diseases and we may witness a delayed surge of hospitalizations related to decompensated liver disease after the COVID‐19 pandemic has receded. Therefore, it is paramount that liver practices craft a comprehensive plan for safe resumption of clinical operations while minimizing the risk of exposure to patients and health‐care professionals. Here, we provide a broad roadmap for how to safely resume care for patients with chronic liver disease according to various phases of the pandemic with particular emphasis on outpatient care, liver transplantation, liver cancer care, and endoscopy.

Background & Aims Glecaprevir/pibrentasvir is approved for treating adults infected with HCV genotypes 1–6. In clinical trials, glecaprevir/pibrentasvir was associated with high rates of sustained virologic response at post-treatment week 12 (SVR12) and was well tolerated. A systematic review and meta-analysis of the real-world effectiveness and safety of glecaprevir/pibrentasvir were undertaken. Methods Real-world studies reporting SVR12 in adults with HCV infection (n ≥20) treated with glecaprevir/pibrentasvir were identified in journal publications from January 1, 2017, to February 25, 2019, and congress presentations through April 14, 2019. Random-effects meta-analysis was used to determine SVR12 rates using data from ≥2 cohorts; intention-to-treat (ITT) analyses included patients treated with glecaprevir/pibrentasvir who had SVR12 data available, discontinued early, or were lost to follow-up; modified ITT (mITT) analyses excluded those with non-virologic failure. Naive pooling was used to calculate adverse event (AE) rates. Results Overall, 12,531 adults were treated with glecaprevir/pibrentasvir (18 cohorts). Of patients with post-treatment week 12 data, SVR12 rates were 96.7% (95% CI 95.4–98.1) in the ITT population (n = 8,583, 15 cohorts) and 98.1% (95% CI 97.1–99.2) in the mITT population (n = 7,001, 14 cohorts). SVR12 rates were ≥95% across subgroups (HCV genotype, cirrhosis status, treatment history, treatment duration, on-label treatment, and subgroups of interest). AEs were reported in 17.7% (1,271/7,199) of patients (8 cohorts). Serious AEs were reported in 1.0% (55/5,522) of patients (6 cohorts). The most frequent AEs were pruritus, fatigue, and headache. AE-related treatment discontinuations were reported in 0.6% (33/5,595) of patients (6 cohorts). Conclusions Consistent with clinical trials, real-world evidence indicates that glecaprevir/pibrentasvir is a well-tolerated and highly effective pangenotypic treatment for a broad range of HCV-infected patients. Lay summary It is important to assess treatments for hepatitis C virus (HCV) in the real world, as patient populations tend to be more diverse and potentially less adherent to treatment compared to those in clinical trials. Results from 18 studies performed in real-world clinics were pooled and analyzed to investigate the effectiveness and safety of a direct-acting antiviral combination (glecaprevir/pibrentasvir) in routine clinical practice. This analysis showed that glecaprevir/pibrentasvir is highly effective and well tolerated across all HCV genotypes and patient groups studied. It also showed that results seen in the real world are similar to the results seen in clinical trials, even in patients historically considered more challenging to treat.

[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 (SVR 12) 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.

[Background and Aim] Histological score systems may not fully capture the essential nonalcoholic steatohepatitis (NASH) features, which is one of the leading causes of screening failure in clinical trials. We assessed the NASH distribution and its components across the fibrosis stages and their impact on the prognosis and their relationship with the concept of metabolic-associated fatty liver disease (MAFLD)., [Methods] Spanish multicenter study including 1893 biopsy-proven nonalcoholic fatty liver disease (NAFLD) patients from HEPAmet registry. NASH was diagnosed by NAS score ≥4 (including steatosis, ballooning and lobular inflammation) and fibrosis by Kleiner score. The presence of MAFLD was determined. Progression to cirrhosis, first episode of decompensated cirrhosis and death were collected during the follow-up (4.7 ± 3.8 years)., [Results] Fibrosis was F0 34.3% (649/1893), F1 27% (511/1893), F2 16.5% (312/1893), F3 15% (284/1893) and F4 7.2% (137/1893). NASH diagnosis 51.9% (982/1893), and its individual components (severe steatosis, ballooning and lobular inflammation), increased from F0 (33.6%) to F2 (68.6%), and decreased significantly in F4 patients (51.8%) (P = .0001). More than 70% of non-NASH patients showed some inflammatory activity (ballooning or lobular inflammation), showing a similar MAFLD rate than NASH (96.2% [945/982] vs. 95.2% [535/562]) and significantly higher than nonalcoholic fatty liver (NAFL) subjects (89.1% [311/349]) (P < .0001). Progression to cirrhosis was similar between NASH (9.5% [51/539]) and indeterminate NASH (7.9% [25/316]), and higher than steatosis (5% [14/263]) (logRank 8.417; P = .015). Death and decompensated cirrhosis were similar between these., [Conclusions] The prevalence of steatohepatitis decreased in advanced liver disease. However, most of these patients showed some inflammatory activity histologically and had metabolic disturbances. These findings should be considered in clinical trials whose main aim is to prevent cirrhosis progression and complications, liver transplant and death., This project has been partially funded by the ‘Consejería de Salud de la Junta de Andalucía’ (PI-0075-2014) and the ‘Spanish Ministry of Economy, Innovation and Competition, Instituto de Salud Carlos III’ (PI19/01404, PI16/01842, PI17/00535 and GLD19/00100).

[Background & Aims] Non-alcoholic fatty liver disease (NAFLD) could play a catalytic role in the development of metabolic comorbidities, although the magnitude of this effect in metabolically healthy patients with NAFLD remains unclear. We assessed the role of biopsy-proven NAFLD on the risk of developing type 2 diabetes mellitus (T2DM) and other metabolic comorbidities (arterial hypertension [AHT], and dyslipidemia) in metabolically healthy patients., [Methods] We included 178 metabolically healthy—defined by the absence of baseline T2DM, AHT, dyslipidemia—patients with biopsy-proven NAFLD from the HEPAmet Registry (N = 1,030). Hepamet fibrosis score (HFS), NAFLD fibrosis score, and Fibrosis-4 were calculated. Follow-up was computed from biopsy to the diagnosis of T2DM, AHT, or dyslipidemia., [Results] During a follow-up of 5.6 ± 4.4 years, T2DM occurred in 9% (16/178), AHT in 8.4% (15/178), low HDL in 9.6% (17/178), and hypertriglyceridemia in 23.6% (42/178) of patients. In multivariate analysis, significant fibrosis predicted T2DM and AHT. Independent variables related to T2DM appearance were significant fibrosis (HR 2.95; 95% CI 1.19–7.31; p = 0.019), glucose levels (p = 0.008), age (p = 0.007) and BMI (p = 0.039). AHT was independently linked to significant fibrosis (HR 2.39; 95% CI 1.14–5.10; p = 0.028), age (p = 0.0001), BMI (p = 0.006), glucose (p = 0.021) and platelets (p = 0.050). The annual incidence rate of T2DM was higher in patients with significant fibrosis (4.4 vs. 1.2 cases per 100 person-years), and increased in the presence of obesity, similar to AHT (4.6 vs. 1.1 cases per 100 person-years). HFS >0.12 predicted the risk of T2DM (25% [4/16] vs. HFS, [Conclusion] Metabolically healthy patients with NAFLD-related significant fibrosis were at greater risk of developing T2DM and AHT. HFS >0.12, but not NAFLD fibrosis score or Fibrosis-4, predicted the occurrence of T2DM., [Lay summary] Patients with biopsy-proven non-alcoholic fatty liver disease and significant fibrosis were at risk of developing type 2 diabetes mellitus and arterial hypertension. The risk of metabolic outcomes in patients with significant fibrosis was increased in the presence of obesity. In addition to liver biopsy, patients at intermediate-to-high risk of significant fibrosis by Hepamet fibrosis score were at risk of type 2 diabetes mellitus., This project has been partially funded by the “Consejería de Salud de la Junta de Andalucía” (PI-0075-2014), the “Spanish Ministry of Economy, Innovation and Competition, Instituto de Salud Carlos III” (PI19/01404, PI16/01842 and PI17/00535) and “Gilead” (GLD19/00100).

Background and aims: Achieving sustained virological response (SVR; cure) in hepatitis C patients using a simple regimen is key to making elimination by 2030 possible. In the largest real-world analysis to date, the effectiveness of pangenotypic, panfibrotic, single-tablet, sofosbuvir/velpatasvir (SOF/VEL) once-daily for 12weeks was assessed in 12 clinical real-world cohorts from various geographical areas, settings and treatment practices. Factors affecting risk of not achieving SVR were assessed. Methods: Adults treated with SOF/VEL 400/100mg, without ribavirin, were included. All HCV patients reaching Week 12 or 24 post-treatment were assessed for SVR12/24. Factors associated with not achieving SVR12/24 for virological reasons were evaluated using logistic regression analysis. Results: Overall, 5552 patients were included: 13.3% treatment-experienced; 20.7% compensated cirrhotic; 30.2% genotype 1; 29.5% genotype 2; 32.9% genotype 3; 4.7% genotype 4; 3.7% HIV coinfection; 13.4% current/former intravenous drug use. Of the 5196 patients evaluated for effectiveness, 98.9% achieved SVR12/24. High SVR12/24 rates occurred in all genotypes including genotype 3 (98.3%; 1649/1677) and in those with compensated cirrhosis (97.9; 1055/1078). Only 55 patients did not achieve SVR12/24 due to a virological reason; the only factor statistically significantly associated with an increased risk of not achieving SVR12/24 was compensated cirrhosis (P=.002). Overall, 6% (332/5552) of patients did not achieve SVR12/24 for non-virological reasons (67% lost to follow-up; 26.5% early treatment discontinuation). Conclusions: In this large cohort, representative of clinical practice, a simple 12-week regimen of SOF/VEL without ribavirin resulted in high SVR12/24 rates in diverse patient populations, even among those with compensated cirrhosis.

Introduction: The appropriate selection of hepatocellular carcinoma (HCC) patients who are eligible for transarterial chemoembolization (TACE) remains a challenge. The ART score has recently been proposed as a method of identifying patients who are eligible or not for a second TACE procedure. Objective: To assess the validity of the Assessment for Retreatment with TACE (ART) score in a cohort of patients treated with drug-eluting bead TACE (DEB-TACE). Secondary objective: to identify clinical determinants associated with overall survival (OS). Method: A retrospective, multicentre study conducted in Spain in patients with HCC having undergone two or more DEB-TACE procedures between January 2009 and December 2014. The clinical characteristics and OS from the day before the second DEB-TACE of patients with a high ART score (ART >= 2.5) and a low ART score (ART 0-1) were compared. Risk factors for mortality were identified using Cox's proportional hazards model. Results: Of the 102 patients included, 51 scored 0-1.5 and 51 scored >= 2.5. Hepatitis C was more frequent in patients scoring >= 2.5. Median OS from the day before the second DEB-TACE was 21 months (95% CI, 15-28) in the group scoring 0-1.5, and 17 months (95% CI, 10-25) in the group scoring >= 2.5 (P=0.3562). Platelet count and tumour size, but not the ART score, were independent baseline predictors of OS. Conclusions: The ART score is not suitable for guiding DEB-TACE retreatment according to Spanish clinical practice standards. (C) 2017 Elsevier Espana, S.L.U., AEEH y AEG. All rights reserved.

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.

Direct-acting antiviral agents (DAAs) are highly effective and well tolerated in patients with chronic hepatitis C virus infection, including those with compensated cirrhosis. However, fewer data are available in patients with more advanced liver disease. Our retrospective, noninterventional, national, multicenter study in patients from the Spanish Hepa-C registry investigated the effectiveness and safety of interferon-free DAA regimens in patients with advanced liver disease, including those with decompensated cirrhosis, in routine practice (all currently approved regimens were registered). Patients transplanted during treatment or within 12 weeks of completing treatment were excluded. Among 843 patients with cirrhosis (Child-Turcotte-Pugh [CTP] class A, n = 564; CTP class B/C, n = 175), 90% achieved sustained virologic response 12 weeks after treatment (SVR12). Significant differences in SVR12 and relapse rates were observed between CTP class A and CTP class B/C patients (94% versus 78%, and 4% versus 14%, respectively; both P < 0.001). Serious adverse events (SAEs) were more common in CTP class B/C versus CTP class A patients (50% versus 12%, respectively; P < 0.001). Incident decompensation was the most common serious adverse event (7% overall). Death rate during the study period was 16/843 (2%), significantly higher among CTP class B/C versus CTP class A patients (6.4% versus 0.9%; P < 0.001). Baseline Model for End-Stage Liver Disease (MELD) score alone (cut-off 18) was the best predictor of survival. Conclusion: Patients with decompensated cirrhosis receiving DAAs present lower response rates and experience more SAEs. In this setting, a MELD score ≥18 may help clinicians to identify those patients with a higher risk of complications and to individualize treatment decisions. (Hepatology 2017;65:1810-1822).

HEPAmet Registry., [Background & Aims] Fibrosis affects prognoses for patients with nonalcoholic fatty liver disease (NAFLD). Several non-invasive scoring systems have aimed to identify patients at risk for advanced fibrosis, but inconclusive results and variations in features of patients (diabetes, obesity and older age) reduce their diagnostic accuracy. We sought to develop a scoring system based on serum markers to identify patients with NAFLD at risk for advanced fibrosis., [Methods] We collected data from 2452 patients with NAFLD at medical centers in Italy, France, Cuba, and China. We developed the Hepamet fibrosis scoring system using demographic, anthropometric, and laboratory test data, collected at time of liver biopsy, from a training cohort of patients from Spain (n = 768) and validated the system using patients from Cuba (n = 344), Italy (n = 288), France (n = 830), and China (n = 232). Hepamet fibrosis score (HFS) were compared with those of previously developed fibrosis scoring systems (the NAFLD fibrosis score [NFS] and FIB-4). The diagnostic accuracy of the Hepamet fibrosis scoring system was assessed based on area under the receiver operating characteristic (AUROC) curve, sensitivity, specificity, diagnostic odds ratio, and positive and negative predictive values and likelihood ratios., [Results] Variables used to determine HFS were patient sex, age, homeostatic model assessment score, presence of diabetes, levels of aspartate aminotransferase, and albumin, and platelet counts; these were independently associated with advanced fibrosis. HFS discriminated between patients with and without advanced fibrosis with an AUROC curve value of 0.85 whereas NFS or FIB-4 did so with AUROC values of 0.80 (P = .0001). In the validation set, cut-off HFS of 0.12 and 0.47 identified patients with and without advanced fibrosis with 97.2% specificity, 74% sensitivity, a 92% negative predictive value, a 76.3% positive predictive value, a 13.22 positive likelihood ratio, and a 0.31 negative likelihood ratio. HFS were not affected by patient age, body mass index, hypertransaminasemia, or diabetes. The Hepamet fibrosis scoring system had the greatest net benefit in identifying patients who should undergo liver biopsy analysis and led to significant improvements in reclassification, reducing the number of patients with undetermined results to 20% from 30% for the FIB-4 and NFS systems (P < .05)., [Conclusions] Using clinical and laboratory data from patients with NAFLD, we developed and validated the Hepamet fibrosis scoring system, which identified patients with advanced fibrosis with greater accuracy than the FIB-4 and NFS systems. the Hepamet system provides a greater net benefit for the decision-making process to identify patients who should undergo liver biopsy analysis.

Background & Aims: Around 5% of patients with chronic hepatitis C virus (HCV) infection treated with direct-acting antiviral (DAA) agents do not achieve sustained virological response (SVR). The currently approved retreatment regimen for prior DAA failure is a combination of sofosbuvir, velpatasvir, and voxilaprevir (SOF/VEL/VOX), although there is little data on its use in clinical practice. The aim of this study was to analyse the effectiveness and safety of SOF/VEL/VOX in the real-world setting. Methods: This was a prospective multicentre study assessing the efficacy of retreatment with SOF/VEL/VOX in patients who had experienced a prior DAA treatment failure. The primary endpoint was SVR 12 weeks after the completion of treatment (SVR12). Data on safety and tolerability were also recorded. Results: A total of 137 patients were included: 75% men, 35% with liver cirrhosis. Most were infected with HCV genotype (GT) 1 or 3. The most common prior DAA combinations were sofosbuvir plus an NS5A inhibitor or ombitasvir/paritaprevirtr +dasabuvir. A total of 136 (99%) patients achieved undetectable HCV RNA at the end of treatment. Overall SVR12 was 95% in the 135 patients reaching this point. SVR12 was lower in patients with cirrhosis (89%, p = 0.05) and those with GT3 infection (80%, p

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.

Background Metabolically healthy obesity (MHO) shows a reduced risk compared with obese patients with adverse metabolic conditions. Lean people suffering some metabolic derangements also have non-alcoholic fatty liver disease (NAFLD)-related outcomes compared with non-obese subjects with a few metabolic risks. Aim To define the impact of the metabolic status on the NAFLD-related outcomes, beyond the presence of obesity. Methods We designed a multicentre cross-sectional study, including 1058 biopsy-proven NAFLD patients. Metabolically healthy status was strictly defined by the lack of metabolic risk factors (diabetes mellitus, low HDL, hypertriglyceridemia, arterial hypertension). Non-alcoholic steatohepatitis (NASH) and significant fibrosis (F2-F4) were identified by liver biopsy. Chronic kidney disease epidemiology collaboration equation was calculated for kidney function and the atherogenic index of plasma (AIP) for cardiovascular risk. Results Metabolically healthy (OR 1.88; P = 0.050) and unhealthy obesity (OR 3.47: P < 0.0001), and unhealthy non-obesity (OR 3.70; P < 0.0001) were independently associated with NASH together with homeostatic model assessment (HOMA), ALT, and platelets. Significant fibrosis was more frequently observed in the presence of adverse metabolic conditions in obese (OR 3.89; P = 0.003) and non-obese patients (OR 3.92; P = 0.002), and independently associated with platelets, albumin, ALT, HOMA, and age. The number of metabolic factors determined the risk of NASH and significant fibrosis. Glomerular filtration rate was lower in unhealthy (91.7 +/- 18) than healthy metabolism (95.6 +/- 17) (P = 0.007). AIP was higher in adverse metabolic conditions (P = 0.0001). Metabolically unhealthy non-obesity showed higher liver damage (NASH 55.8% vs 42.4%; P P < 0.0001) and cardiovascular risk (P < 0.0001) than healthy obesity. Conclusions Metabolic unhealthy status showed a greater impact on NASH, significant fibrosis, kidney dysfunction, and atherogenic profile than obesity. However, metabolically healthy obesity was not a full healthy condition. We should focus our messages especially on patients with adverse metabolic conditions.

The Barcelona Clinic Liver Cancer (BCLC) classification of hepatocellular carcinoma (HCC) has proved useful in the management of HCC patients. However, BCLC-recommended first-line treatment is not always applicable in clinical practice.We performed a multicentre retrospective analysis of reasons for deviation from first-line treatment in 2008-2012.One to three-year survival data were analysed using Kaplan-Meier method.A total of 407 consecutive HCC patients (66.6 ± 3 years, 83% male) with cirrhosis were included. Tumours were detected during surveillance in 53% of patients, grouped as Child-Pugh A (67%), B (25%) and C (8%); and BCLC A (including stage 0, 44%), B (26%), C (15%) and D (15%). In 31% of patients, first-line treatment was not feasible (51% in early stages) due to: technical reasons (74%); patient non-conformity (20%); medical decision (3%); and disease progression (3%). One to three-year survival of patients not receiving the recommended first-line treatment was similar to that of patients treated according to BCLC recommendations (log-rank, p = 0.229).In real-life practice one-third of HCC patients could not receive first-line BCLC treatment. In our cohort of patients, similar short and medium-term survival was observed. Long-term prospective studies are required to determine the best alternative treatment option when BCLC first-line treatment is not feasible.

[Abstract] Background and Aims. Hepatitis C (HCV) therapy with Sofosbuvir (SOF)/Simeprevir (SMV) in clinical trials and real‐world clinical practice, showed high rates of sustained virological response (SVR) in non‐cirrhotic genotype (GT)‐1 and GT‐4 patients. These results were slightly lower in cirrhotic patients. We investigated real‐life effectiveness and safety of SOF/SMV with or without ribavirin (RBV) in a large cohort of cirrhotic patients. Methods. This collaborative multicentre study included data from 968 patients with cirrhosis infected with HCV‐GT1 or 4, treated with SOF/SMV±RBV in 30 centres across Spain between January‐2014 and December‐2015. Demographic, clinical, virological and safety data were analysed. Results. Overall SVR was 92.3%; the majority of patients were treated with RBV (62%) for 12 weeks (92.4%). No significant differences in SVR were observed between genotypes (GT1a:94.3%; GT1b:91.7%; GT4:91.1%). Those patients with more advanced liver disease (Child B/C, MELD≥10) or portal hypertension (platelet count≤100×109/L, transient elastography≥21 Kpa) showed significantly lower SVR rates (84.4%‐91.9%) than patients with less advanced liver disease (93.8%‐95.9%, P

Patients with HCV genotype 3 (GT3) infection and cirrhosis are currently the most difficult to cure. We report our experience with sofosbuvir+daclatasvir (SOF+DCV) or sofosbuvir/ledipasvir (SOF/LDV), with or without ribavirin (RBV) in clinical practice in this population. This was a multicenter observational study including cirrhotic patients infected by HCV GT3, treated with sofosbuvir plus an NS5A inhibitor (May 2014-October 2015). In total, 208 patients were included: 98 (47%) treatment-experienced, 42 (20%) decompensated and 55 (27%) MELD score >10. In 131 (63%), treatment was SOF+DCV and in 77 (37%), SOF/LDV. Overall, 86% received RBV. RBV addition and extension to 24 weeks was higher in the SOF/LDV group (95% vs 80%, P=.002 and 83% vs 72%, P=.044, respectively). A higher percentage of decompensated patients were treated with DCV than LDV (25% vs 12%, P=.013). Overall, SVR12 was 93.8% (195/208): 94% with SOF+DCV and 93.5% with SOF/LDV. SVR12 was achieved in 90.5% of decompensated patients. Eleven treatment failures: 10 relapses and one breakthrough. RBV addition did not improve SVR (RR: 1.08; P=.919). The single factor associated with failure to achieve SVR was platelet count 10. In 131 (63%), treatment was SOF+DCV and in 77 (37%), SOF/LDV. Overall, 86% received RBV. RBV addition and extension to 24 weeks was higher in the SOF/LDV group (95% vs 80%, P=.002 and 83% vs 72%, P=.044, respectively). A higher percentage of decompensated patients were treated with DCV than LDV (25% vs 12%, P=.013). Overall, SVR12 was 93.8% (195/208): 94% with SOF+DCV and 93.5% with SOF/LDV. SVR12 was achieved in 90.5% of decompensated patients. Eleven treatment failures: 10 relapses and one breakthrough. RBV addition did not improve SVR (RR: 1.08; P=.919). The single factor associated with failure to achieve SVR was platelet count

Background & Aims The combination of β-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 β-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.

Background & Aims Simvastatin improves liver generation of nitric oxide and hepatic endothelial dysfunction in patients with cirrhosis, so it could be an effective therapy for portal hypertension. This randomized controlled trial evaluated the effects of continuous simvastatin administration on the hepatic venous pressure gradient (HVPG) and its safety in patients with cirrhosis and portal hypertension. Methods Fifty-nine patients with cirrhosis and portal hypertension (HVPG ≥12 mm Hg) were randomized to groups that were given simvastatin 20 mg/day for 1 month (increased to 40 mg/day at day 15) or placebo in a double-blind clinical trial. Randomization was stratified according to whether the patient was being treated with β-adrenergic blockers. We studied splanchnic and systemic hemodynamics and variables of liver function and safety before and after 1 month of treatment. Results Simvastatin significantly decreased HVPG (−8.3%) without deleterious effects in systemic hemodynamics. HVPG decreases were observed in patients who were receiving β-adrenergic blockers (−11.0%; P = .033) and in those who were not (−5.9%; P = .013). Simvastatin improved hepatic, fractional, and intrinsic clearance of indocyanine green, showing an improvement in effective liver perfusion and function. No significant changes in HVPG and liver function were observed in patients receiving placebo. The number of patients with adverse events did not differ significantly between groups. No patient was withdrawn from the study based on adverse events. Conclusions Simvastatin decreased HVPG and improved liver perfusion in patients with cirrhosis. These effects were additive with those of β-adrenergic blockers. The beneficial effects of simvastatin should be confirmed in long-term clinical trials for portal hypertension.

Background & Aims Acute portal vein thrombosis (APVT) is a rare disorder that causes chronic portal hypertension if recanalization is not obtained. However, response to anticoagulation and long-term prognosis of APVT are not well-defined. Methods Thirty-eight patients diagnosed with APVT between 1995 and 2003 from 5 Spanish referral hospitals, in whom cirrhosis and malignancy were specifically excluded, were included in this retrospective study. The response to anticoagulation therapy and development of portal hypertension–related complications during follow-up were evaluated. Results Mean follow-up was 43 months (range, 6–112 months). Recanalization occurred in 12 of 27 patients receiving anticoagulation versus 0 of 11 patients who did not receive anticoagulation ( P = .008). Rates of recanalization were influenced by the precocity of heparin administration and the number of underlying prothrombotic conditions. Follow-up upper endoscopy performed in 29 patients disclosed gastroesophageal varices in 16 (55%). Varices appeared as early as 1 month after APVT. However, in most patients varices were detected in successive endoscopies, mainly during the first year. Two-year actuarial probability of variceal bleeding was 12% and for ascites 16%. Five-year survival was 87%. Mortality was related to the APVT episode in 2 cases and to an underlying hematologic disorder in one. Conclusions Anticoagulation achieved recanalization in about 40% of patients. Most patients not achieving recanalization will develop gastroesophageal varices during follow-up. However, development of variceal bleeding and ascites is infrequent, and survival is satisfactory.

SUMMARY Aims: To evaluate sorafenib dosing and safety in the Global Investigation of therapeutic GIDEON study's European subpopulation. Patients & methods: Patient demographics, disease characteristics and treatment history were recorded at enrollment; dose, adverse events and efficacy were recorded at follow-up. Results: Of 1113 evaluable patients, 82% started on 800 mg/day sorafenib; patients starting on 400 mg/day were slightly older, had baseline characteristics indicative of greater disease progression and higher adverse events incidences (96 vs 88%). Treatment duration (18.0 vs 13.0 weeks) and median overall survival (12.1 vs 9.4 months) were longer in patients receiving 800 mg/day. Conclusion: Imbalances in independent predictive factors may have led to longer survival in patients receiving 800 mg/day sorafenib; nonetheless, results suggest that the majority can start on this dose.

Background Virological response to peginterferon + ribavirin (P+R) at week 4 can predict sustained virological response (SVR). While patients with rapid virological response (RVR) do not require triple therapy, patients with a decline

Budd-Chiari syndrome (BCS) causes postsinusoidal portal hypertension, which leads to complications similar to those observed in cirrhosis. However, no studies have investigated whether patients with BCS develop the hyperdynamic circulatory syndrome present in patients with cirrhosis who have portal hypertension. We evaluated systemic and cardiopulmonary hemodynamics, plasma renin activity, aldosterone and norepinephrine levels, and plasma volume in patients with BCS admitted for complications of portal hypertension. BCS patients had mean systemic and cardiopulmonary pressures and cardiac indices that were within the normal range but were significantly different from those of a group of patients with cirrhosis matched by sex, body surface, and liver function (cardiac index 3.1 +/- 0.7 vs. 4.9 +/- 1.2 L.min(-1).m(-2); P < .001; systemic vascular resistance [SVR] index, 2,189 +/- 736 vs. 1,377 +/- 422 dyne.s.cm(-5).m(-2), P < .001). Despite normal systemic vascular resistance, BCS patients had activation of the neurohumoral vasoactive systems, as evidenced by increased plasma renin activity, aldosterone and norepinephrine levels (15.0 +/- 21.5 ng/mL . h, 76.7 +/- 106.8 ng/dL, 586 +/- 868 pg/mL; respectively) and plasma volume expansion. The analysis of individual BCS patients identified that 7 of the 21 patients actually had reduced SVR index. These patients had the greatest plasma volume expansion. A significant inverse correlation between plasma volume and SVR index was observed. In conclusion, patients with BCS had activation of vasoactive neurohumoral systems and expanded plasma volume. This outcome was observed even though most of these patients did not exhibit systemic vasodilation and cardiac output was not increased, in marked contrast with what is observed in patients with cirrhosis.

The beta-2-adrenergic receptor (beta(2-)-AR) has several single-nucleotide polymorphisms. These influence the functional response to adrenergic stimulation; genotypes homozygous for Gly16-Glu27 or Gly16-Gln27 alleles (Gly16-Glu/Gln27 haplotypes) are associated with enhanced response, whereas genotypes homozygous for Arg16-Gln27 alleles (Arg16-Gln27) show a decreased response. We hypothesized that gene polymorphisms at the beta2-AR may influence the hemodynamic response to propranolol in patients with cirrhosis. The beta2-AR gene polymorphisms were determined by direct sequencing of the polymerase chain reaction (PCR) products in 48 patients with cirrhosis. All patients also had hepatic and systemic hemodynamic studies before and after propranolol administration. Prevalence of Gly16-Glu/Gln27 haplotypes was 29.1%, Arg16-Gln27 haplotype was 16.7%, and 54.2% were compound heterozygotes. Patients with cirrhosis with Gly16-Glu/Gln27 haplotypes had a greater decrease in heart rate, cardiac index, and hepatic blood flow after propranolol administration than those with Arg16-Gln27 haplotype. However, the HVPG response to propranolol was similar in both groups, whereas estimated hepatic sinusoidal resistance increased significantly in Gly16-Glu/Gln27 haplotypes but not in Arg16-Gln27 (+27.1 +/- 17.8% vs -17.9 +/- 13.9%, P = .042), suggesting that unopposed vasoconstrictive activity at the intrahepatic circulation hinders the fall in HVPG despite enhanced hemodynamic response to propranolol in Gly16-Glu/Gln27 haplotypes. In conclusion, beta2-AR gene polymorphisms influence the response to beta-blockade. However, HVPG reduction cannot be predicted from polymorphism analysis. Patients with the Gly16-Glu/Gln27 haplotypes may benefit from the association of hepatic vasodilators to propranolol therapy.

Background An independent meta-analysis of randomized comparative trials of peginterferons alfa-2a and alfa-2b, both combined with ribavirin, analyzed the probability of achieving a sustained virological response (SVR). Objective To estimate the long-term cost-effectiveness of treatment of patients with chronic hepatitis C with peginterferon alfa-2a (180 μg/week) plus ribavirin (800–1200 mg/day) vs. alfa-2b (1.5 μg/kg/week) plus ribavirin (800–1400 mg/day), from the perspective of the Spanish National Health System. Methods A Markov model was developed with 7 health states to simulate lifetime disease progression. SVR was calculated from the meta-analysis data. Transition probabilities and health state utilities were obtained from published literature. Direct healthcare costs were obtained from the drug catalog, while costs of disease-related complications were obtained from published studies and healthcare cost database. Costs were expressed in 2010€. The annual discount rate applied was 3.5% for both costs and benefits. Results SVR rate for treatment with alfa-2a was higher than with alfa-2b; the differences were 6.0%, 7.6% and 8.7% for all genotypes, genotypes 1/4 and genotypes 2/3, respectively. Each patient would gain 0.469, 0.600 and 0.685 life-years and 0.155, 0.198 and 0.227 quality-adjusted life-years with alfa-2a vs. alfa-2b, for the respective genotypes. The cost saving per patient treated with alfa-2a would be €705, €672 and €1900, for all genotypes and for genotypes 1/4 and 2/3, respectively, alfa-2a being dominant. Conclusions According to the present model, treatment of patients with chronic hepatitis C with peginterferon alfa-2a is cost-effective compared with peginterferon alfa-2b, both combined with ribavirin.

Summary Background A Cochrane meta-analysis established that pegylated interferon α-2a is more effective than peginterferon α-2b in terms of sustained virological response (SVR) in the treatment of chronic hepatitis C. Rapid virological response (RVR) and early virological response (EVR) are crucial to reach SVR and to make clinical decisions. Aim To compare RVR and EVR rates of peginterferon α-2a vs. peginterferon α-2b through a meta-analysis of previously published randomised control trials (RCT). Methods MEDLINE, EMBASE and LILACS databases were systematically searched up to September 2011. Seven RCT that reported complete early virological response (cEVR) were selected. A meta-analysis focusing on RVR and cEVR outcomes was conducted and Relative Efficacy (RE) was calculated. Results Meta-analysis of cEVR included seven trials (n = 4359), and yielded an estimated effect in favour of peginterferon α-2a: Crude Efficacy (CEf) was 53.3% vs. 43.8%, RE = 1.118 (CI 95% = 1.039–1.203; P = 0.0028), heterogeneity Q = 8.959; I2 = 33.0% (P = 0.1759). A sub-analysis of three studies with 3409 genotype-1 patients yielded CEf: 49.4% vs. 40.2%, RE = 1.151 (CI 95% = 0.968–1.369; P = 0.1124), Q = 9.802; I2 = 79.6% (P = 0.0074). Meta-analysis of RVR included five trials (n = 3833) with an estimated effect in favour of peginterferon α-2a: CEf = 25.0% vs. 16.8%, RE = 1.151 (CI 95%:1.042–1.272; P = 0.0056), Q = 1.461; I2 = 0.0% (P = 0.8335). Analysis of four studies reporting RVR including 3499 patients with genotypes 1 and 4 resulted in CEf: 18.3% vs. 12.7% RE = 1.206 (CI 95% = 1.059–1.374; P = 0.0048), Q = 1.116; I2 = 0.0% (P = 0.7733). Conclusions Peginterferon α-2a may be associated with a higher cEVR and RVR than peginterferon α-2b. These findings could help to achieve higher SVR rates and support clinical decision-making in the present scenario of triple combination therapy.

We present the case of a cirrhotic patient with ascites and an albumin gradient of less than 1.1 g/dl. After endoscopic tests, including upper gastrointestinal endoscopic ultrasound-guided fine-needle aspiration, exploratory laparoscopy was performed to provide the diagnosis, revealing mucin throughout the peritoneal cavity and nodules on the parietal and visceral peritoneum. Histopathological analysis established the diagnosis as peritoneal pseudomyxoma. This uncommon entity, which has a poor prognosis without treatment, is most frequently associated with mucinous tumors of the appendix, and secondly, with tumors of the ovary.

Objetivo: conocer la incidencia, forma de presentación, localización y resultados del tratamiento endoscópico en la hemorragia digestiva causada por lesión de Dieulafoy. Material y métodos: se revisaron de forma retrospectiva todos los casos de hemorragia digestiva por lesión de Dieulafoy entre los años 2000 y 2006. Se recogieron los principales datos clínicos y endoscópicos, tipo de tratamiento empleado, eficacia del mismo, recidiva, complicaciones y mortalidad durante el ingreso. Resultados: se encontraron 41 pacientes, 26 varones y 15 mujeres, con edad media de 71,19 años. La lesión de Dieulafoy fue la causa del 1,55% de los casos de hemorragia digestiva aguda en el periodo estudiado. La incidencia de hemorragia digestiva por lesión de Dieulafoy fue de 2,2 casos por cada 100.000 habitantes y año. La mayoría de los pacientes presentaban hemorragia activa en el momento de la endoscopia (85,36%) y comorbilidad (92,68%). La localización más frecuente fue el estómago (60,97%), seguida del duodeno (29,26%). El tratamiento endoscópico logró la hemostasia inicial en el 100% de los casos. Tres pacientes (7,31%) presentaron recidiva hemorrágica, todos ellos habían sido tratados inicialmente con esclerosis con adrenalina y respondieron adecuadamente a un segundo tratamiento endoscópico. Ningún paciente precisó cirugía. La mortalidad durante el ingreso fue del 4,87%. Conclusiones: la lesión de Dieulafoy es una causa poco frecuente, pero potencialmente grave, de hemorragia digestiva y puede aparecer en cualquier punto del tracto gastrointestinal. El tratamiento endoscópico es eficaz y presenta pocas complicaciones. La esclerosis única con adrenalina se asocia a un mayor riesgo de recidiva hemorrágica.

A reduction in hepatic venous pressure gradient (HVPG) ofor =20% of baseline or toor =12 mmHg (responders) is associated with a reduced risk of first variceal bleeding. The aim of this study was to evaluate whether this protective effect is maintained in the long term and if it extends to other portal hypertension complications.Seventy-one cirrhotic patients with esophageal varices and without previous variceal bleeding who entered into a program of prophylactic pharmacological therapy and were followed for up to 8 yr were evaluated. All had two separate HVPG measurements, at baseline and after pharmacological therapy with propranolol +/- isosorbide mononitrate.Forty-six patients were nonresponders and 25 were responders. Eight-year cumulative probability of being free of first variceal bleeding was higher in responders than in nonresponders (90% vs 45%, p= 0.026). The lack of hemodynamic response and low platelet count were the only independent predictors of first variceal bleeding. Additionally, reduction of HVPG was independently associated with a decreased risk of spontaneous bacterial peritonitis (SBP) or bacteremia. No significant differences in the development of ascites, hepatic encephalopathy, or survival were observed.The hemodynamic response in cirrhotic patients is associated with a sustained reduction in the risk of first variceal bleeding over a long-term follow-up. Reduction of HVPG also correlate with a reduced risk of SBP or bacteremia.

Background & Aims: In cirrhosis, an insufficient release of nitric oxide contributes to increased hepatic resistance and portal pressure and enhances the postprandial increase in portal pressure. We hypothesized that simvastatin, which enhances Akt-dependent endothelial nitric oxide synthase phosphorylation, may increase hepatic nitric oxide release and decrease hepatic resistance in patients with cirrhosis and portal hypertension. Methods: In protocol 1, 13 patients had measurements of the hepatic venous pressure gradient, hepatic blood flow, mean arterial pressure, cardiac output, and nitric oxide products before and 30 and 60 minutes after 40 mg of simvastatin. In protocol 2, 17 patients were randomized to receive placebo or simvastatin (40 mg) 12 hours and 1 hour before the study. After baseline measurements of the hepatic venous pressure gradient, hepatic blood flow, and nitric oxide products, a standard liquid meal was given, and measurements were repeated at 15, 30, and 45 minutes. Results: In protocol 1, acute simvastatin did not modify the hepatic venous pressure gradient but increased the hepatic blood flow (21% ± 13% at 30 minutes; P = 0.01) and decreased hepatic sinusoidal resistance by 14% ± 11% ( P = 0.04). Nitric oxide product levels significantly increased in hepatic venous blood (from 31.4 ± 12.3 nmol · mL −1 to 35.8 ± 10.7 nmol · mL −1 ; P = 0.04), but not in peripheral blood. Systemic hemodynamics were not modified. In protocol 2, simvastatin pretreatment significantly attenuated the postprandial increase in hepatic venous pressure gradient (mean peak increase, 10% ± 9% vs. 21% ± 6% in placebo; P = 0.01). Hepatic blood flow increased similarly in the 2 groups. Hepatic nitric oxide products increased in the simvastatin group but not in the placebo group. Conclusions: Simvastatin administration increases the hepatosplanchnic output of nitric oxide products and decreases hepatic resistance in patients with cirrhosis.

Available evidence supports the concept that repeat measurements of hepatic venous pressure gradient (HVPG) adequately predict the effectiveness of drug therapy for portal hypertension1, 2, 3, 4, 5, 6, 7. The HVPG response to continued pharmacologic therapy correlates well with the risk of first variceal bleeding3, 8 or rebleeding2, 4. Patients who experienced a decrease in HVPG to < 12 mmHg have an extremely low risk of rebleeding (“optimal” hemodynamic response). Even if the final HVPG is not reduced < 12 mmHg, a decrease of over 20% of baseline values is also associated with a marked reduction in the risk of bleeding of about 19.5% vs 45% in non-responders (“good” hemodynamic response) (Table 1). Unfortunately such hemodynamic responses are achieved in only about 30–60% of patients receiving non-selective beta-blockers. Lack of achievement of these targets constitutes the strongest independent predictor of variceal bleeding or rebleeding2, 3, 4, 10. Therefore, ideally, the treatment of portal hypertension should be guided by measuring the individual portal pressure response to therapy. This allows us to predict whether the treatment is likely to offer optimal or adequate protection from the risk of bleeding on follow-up10, 11.

In cirrhotic patients under pharmacologic treatment for portal hypertension, a reduction in hepatic venous pressure gradient (HVPG) of ≥20% of baseline or to ≤12 mm Hg markedly reduces the risk of variceal rebleeding. This study was aimed at evaluating whether these hemodynamic targets also prevent other complications of portal hypertension and improve long-term survival. One hundred five cirrhotic patients included in prospective trials for the prevention of variceal rebleeding were studied. Seventy-three of the patients had 2 separate HVPG measurements, at baseline and under pharmacologic therapy with propranolol ± isosorbide mononitrate. Patients were followed for up to 8 years. Survival and risk of developing portal hypertension-related complications were compared between responders and nonresponders. Twenty-eight patients showed a reduction of HVPG ≥20% of baseline or to ≤12 mm Hg (responders), and 45 patients were nonresponders. Nonresponders had a significantly greater risk of developing variceal rebleeding (P = .013), ascites (P = .025), spontaneous bacterial peritonitis (P = .003), hepatorenal syndrome (P = .026), and hepatic encephalopathy (P = .024) than responders. Eight-year cumulative probability of survival was significantly lower in nonresponders than in responders (52% vs. 95%, respectively, P = .003). At multivariate analysis, being a nonresponder was independently associated with the risk of developing rebleeding, ascites, spontaneous bacterial peritonitis, and lower survival. In conclusion, in cirrhotic patients receiving pharmacologic treatment for prevention of variceal rebleeding, a decrease in HVPG ≥20% or to ≤12 mm Hg is associated with a marked reduction in the long-term risk of developing complications of portal hypertension and with improved survival.

4088 Background: The global, prospective, non-interventional GIDEON study recruiting >3,000 patients with unresectable hepatocellular carcinoma treated with sorafenib is complete. We report the fin...

Introduction GIDEON (Global Investigation Of Therapeutic Decisions In Hepatocellular Carcinoma (HCC) And Of Its Treatment With Sorafenib) is an ongoing, global, prospective, non-interventional study of patients with HCC eligible for and receiving sorafenib under real-life practice conditions. It aims to assess safety and efficacy of sorafenib in different settings and patient subgroups where data are limited. Findings from the second interim analysis (1571 patients treated for ≥4 months) have been reported. Here we report details of AEs in the European subset. Methods Patient demographics, medical, disease and treatment history are recorded at enrolment; sorafenib dose, performance status, liver function, AEs and efficacy are recorded at follow-up. Results 588 of the 1571 patients were treated in Europe: 59.4% aged ≥65 years, ECOG performance status (PS) 0/1, 45.9/38.9%, and BCLC stage A/B/C/D, 9.0/24.3/52.9/4.9%. Treating physicians’ predominant specialty was hepatology/gastroenterology (56.5% of patients) and medical oncology (32.1%). Most patients (80.6%) were started on sorafenib 800mg daily. Sorafenib dose was modified for 40.8% of patients; 29.8% due to AEs. The dose was increased in 13.8% of patients and decreased in 33.7%. Treatment was interrupted in 20.1% of patients; 16.2% due to AEs. Median treatment duration was 14.3 weeks. Median daily dose was 746mg. A total of 84.5% of patients experienced a treatment-emergent AE. The overall incidence was similar in patients aged Conclusion The results did not reveal any unexpected AEs and indicate that the incidence of AEs among patients treated with sorafenib in routine clinical practice appears similar to those treated in randomized clinical trials. Furthermore, these data suggest that a modified dosing strategy did not improve upon the incidence of AEs associated with the standard 800mg daily dose of sorafenib.
