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: Despite secondary-prophylaxis with beta-blockers and endoscopic-variceal-ligation rebleeding is frequent, particularly within the first-6-weeks. Early-rebleeding may have greater impact on death-risk than late rebleeding, which may affect therapy. We assessed whether the influence of rebleeding on long-term survival of patients on secondary-prophylaxis is greater in patients with early-rebleeding. Methods: 369 patients with cirrhosis were consecutively included once recovered from first variceal-bleeding. The impact of rebleeding on survival was investigated according to whether it occurred within 6-weeks (early-rebleeding) or later (late-rebleeding). Results: During 46-months of follow-up (IQR: 14-61), 45 patients (12%) had early-rebleeding, 74(20%) had late-rebleeding and 250(68%) had not rebleeding. Mortality risk was higher in early-rebleeding group vs. late-rebleeding (HR = 0.476, 95%CI = 0.318-0.712, p < 0.001) and was similar in late-rebleeding group vs. no-rebleeding (HR = 0.902, 95%CI = 0.749-1.086, p = 0.271). Adjusting for baseline risk-factors, early-rebleeding was independently associated with mortality-risk (HR = 1.58, 95%CI = 1.02-2.45; p = 0.04). Child-Pugh&MELD scores improved at 3rd-4th-week only in patients without early-rebleeding (p < 0.05). Presence of ascites or encephalopathy, MELD-score>12 and HVPG>20 mmHg identified patients at risk of early-rebleeding. Conclusions: Patients with early-rebleeding have higher risk of death than patients without rebleeding and even than those rebleeding later. Our results suggest that patients at risk of early rebleeding might benefit from preemptive therapies such as early-TIPS. (C) 2020 Editrice Gastroenterologica Italiana S.r.l.

Background & Aims: Whether the effect of beta-blockers on arterial pressure and/or cardiac function may offset the benefit of reducing portal pressure in advanced cirrhosis is controversial. Herein, we aimed to evaluate the systemic and splanchnic hemodynamic effects of beta-blockers in decompensated vs. compensated cirrhosis and to investigate the influence of systemic hemodynamic changes on survival times in decompensated cirrhosis. Methods: Patients with cirrhosis and high-risk esophageal varices, without previous bleeding, were consecutively included and grouped according to the presence or absence of decompensation (ascites with or without overt encephalopathy). Systemic and hepatic hemodynamic measurements were performed before starting beta-blockers and again after 1 to 3 months of treatment (short-term). Results: Four hundred and three patients were included (190 decompensated and 213 compensated). At baseline, decompensated patients had higher portal pressure than compensated patients and were more hyperdynamic, with higher cardiac output (CO) and lower arterial pressure. Under -blockers, decompensated patients had lower portal pressure decrease (10 +/- 18% vs. 15 +/- 12%; p

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.

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.

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 & AimsDrug-drug interactions (DDIs) with ombitasvir/paritaprevir/ritonavir with or without dasabuvir and with or without ribavirin (OBV/PTV/rDSVRBV) are common in clinical trials. Our aim was to analyze the prevalence and management of potential DDIs and adverse events (AEs) related to DDIs in patients with chronic hepatitis C (CHC) receiving OBV/PTV/rDSV +/- RBV in clinical practice. Methods177 CHC patients started OBV/PTV/r +/- DSV +/- RBV in 4 Spanish hospitals and were screened for potential DDIs using the University of Liverpool database. Patients were classified according to the most serious potential DDIs at baseline and AEs during therapy. ResultsAt least one potential DDI was found in 110 (62.1%) patients: 100 (56.5%) had at least one manageable potential DDI and 10 (5.6%) at least one contraindicated. Patients with potential DDIs were receiving a higher number of concomitant drugs (4 vs. 2, P

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.

The most reliable indicators for post-ERCP acute pancreatitis are elevated amylase levels and abdominal pain 24 hours after ERCP. As ERCP is often performed on an outpatient basis, earlier diagnosis is important. We aimed to identify early predictors of post-ERCP pancreatitis. We prospectively analyzed IL-6, IL-10, TNF alpha, CRP, amylase and lipase before and 4 hours after ERCP, and studied their association with abdominal pain. We included 510 patients. Post-ERCP pancreatitis occurred in 36 patients (7.1%). IL-6, IL-10, TNF alpha and CRP were not associated with post-ERCP pancreatitis. Levels of amylase and lipase were higher in patients with pancreatitis (522 U/L and 1808 U/L vs. 78 U/L and 61 U/L, respectively; p < 0.001). A cut-off of 218 U/L for amylase (x2.2 ULN) and 355 U/L for lipase (x6 ULN) had a negative predictive value of 99.2% and 99.5%, respectively. Amylase and lipase present a good correlation (Pearson coefficient 0.912). Among 342 (67.1%) patients without abdominal pain at 4 hours, post-ERCP pancreatitis was diagnosed in 8 (2.3%). Only 4 of these patients presented amylase or lipase > 3 ULN. Amylase and lipase were the only markers of post-ERCP pancreatitis 4 hours after the procedure.

Falls are frequent among patients with debilitating disorders and can have a serious effect on health status. Mild cognitive disturbances associated with cirrhosis may increase the risk for falls. Identifying subjects at risk may allow the implementation of preventive measures. Our aim was to assess the predictive value of the Psychometric Hepatic Encephalopathy Score (PHES) in identifying patients likely to sustain falls. One hundred and twenty-two outpatients with cirrhosis were assessed using the PHES and were followed at specified intervals. One third of them exhibited cognitive dysfunction (CD) according to the PHES (

OBJECTIVES: In compensated cirrhosis, a threshold value of hepatic venous pressure gradient (HVPG) >= 10 mm Hg is required for the development of decompensation. However, whether the treatment of portal hypertension (PHT) can prevent the transition into development of ascites once this level has been reached is unclear. Our aim was to assess the relationship between changes in HVPG induced by beta-blockers and development of ascites in compensated cirrhosis with severe PHT. METHODS: Eighty-three patients without any previous decompensation of cirrhosis, with large esophageal varices and HVPG >= 12 mm Hg were included. After baseline hemodynamic measurements nadolol was administered and a second hemodynamic study was repeated 1-3 months later. RESULTS: During 53 +/- 30 months of follow-up, decompensation occurred in 52 patients (62%) and in 81% of them ascites was the first manifestation. Using receiver operating characteristic curve analysis a decrease in HVPG >= 10% was the best cutoff to predict ascites. As compared with nonresponders, patients with an HVPG decrease >= 10% had a lower probability of developing ascites (19% vs. 57% at 3 years, P= 10% significantly reduces the risk of developing ascitic decompensation and other related complications such as refractory ascites or hepatorenal syndrome.

Hepatic venous pressure gradient (HVPG) monitoring of therapy to prevent variceal rebleeding provides strong prognostic information. Treatment of nonresponders to beta-blockers +/- nitrates has not been clarified. To assess the value of HVPG-guided therapy using nadolol + prazosin in nonresponders to nadolol + isosorbide-5-mononitrate (ISMN) compared with a control group treated with nadolol + ligation. Cirrhotic patients with variceal bleeding were randomized to HVPG-guided therapy (n = 30) or nadolol + ligation (n = 29). A Baseline haemodynamic study was performed and repeated within 1 month. In the guided-therapy group, nonresponders to nadolol + ISMN received nadolol and carefully titrated prazosin and had a third haemodynamic study. Nadolol + prazosin decreased HVPG in nonresponders to nadolol + ISMN (P < 0.001). Finally, 74% of patients were responders in the guided-therapy group vs. 32% in the nadolol + ligation group (P < 0.01). The probability of rebleeding was lower in responders than in nonresponders in the guided therapy group (P < 0.01), but not in the nadolol + ligation group (P = 0.41). In all, 57% of nonresponders rebled in the guided-therapy group and 20% in the nadolol + ligation group (P = 0.05). The incidence of complications was similar. In patients treated to prevent variceal rebleeding, the association of nadolol and prazosin effectively rescued nonresponders to nadolol and ISMN, improving the haemodynamic response observed in controls receiving nadolol and endoscopic variceal ligation. Our results also suggest that ligation may rescue nonresponders.

BACKGROUND & AIMS: Studies of variceal bleeding have shown that a hemodynamic response to treatment of portal hypertension is appropriate when the hepatic venous pressure gradient (HVPG) decreases below 12 mmHg or by >20% from baseline. However, in primary prophylaxis, many nonresponders do not bleed and 2 invasive procedures are needed to assess response. We investigated the long-term prognostic value of an acute response to beta-blockers and whether the target reduction in HVPG can be improved in primary prophylaxis. METHODS: An initial hemodynamic study was performed in patients with large varices and without previous bleeding. After baseline measurements were made, propranolol was administered intravenously and measurements were repeated 20 minutes later. Patients were given nadolol daily and a second hemodynamic study was performed. RESULTS: Of 105 patients, 15% had variceal bleeding. Using receiver operating characteristic curve analysis, a decrease of HVPG >= 10% was the best value to predict bleeding. In the initial study, 75 patients (71%) were responders (HVPG decreased to = 10%) and had a lower probability of first bleeding than nonresponders (4% vs 46% at 24 months; P < .001). Acute responders also had a lower risk of developing ascites (P = .001). Chronic responders had a lower probability of bleeding than nonresponders (P < .001). There was a correlation between acute and chronic changes in HVPG (r = 0.62; P = .01). CONCLUSION: The acute hemodynamic response to beta-blockers can be used to predict the long-term risk of first bleeding. An HVPG reduction > 10% from baseline is the best target to define response in primary prophylaxis. To view this article's video abstract, go to the AGA's YouTube Channel.
