Validation of the new 2021 EASL algorithm for the noninvasive diagnosis of advanced fibrosis in NAFLD.

BACKGROUND AND AIMS: The European Association for the Study of the Liver (EASL) has recently proposed an algorithm for the diagnosis of advanced liver fibrosis. We aimed to evaluate the diagnostic accuracy of this algorithm in nonalcoholic fatty liver disease (NAFLD). APPROACH AND RESULTS: One thousand fifty-one patients with NAFLD, liver biopsy, and four noninvasive tests (NITs; Fibrosis-4 [FIB4], vibration controlled transient elastography [VCTE], FibroMeter, Fibrotest) were included. The enhanced liver fibrosis (ELF) score was available in 396 patients. A cohort of 230 patients from primary care/diabetes clinics had FIB4, VCTE, and ELF. Compared with the performance of single NITs, agreement between two NITs (FIB4 and VCTE, VCTE and patented serum tests) increased specificity and positive predictive value by 20%, thus justifying the sequential use proposed in the EASL algorithm. The FIB4/VCTE/FibroMeter and FIB4/VCTE/Fibrotest algorithms performed similarly, providing 85% diagnostic accuracy and a liver biopsy requirement rate of only 10%. The FIB4/VCTE/ELF algorithm performed similarly in the subgroup where ELF was available. Simulations of algorithm accuracies at different prevalence showed that positive predictive values rapidly increased, reaching a plateau above 75% starting at 15% prevalence. Negative predictive values remained higher than 90% up to 25% prevalence. The rate of liver biopsy requirement remained stable, increasing by only 5% between low and high prevalence settings. When the EASL algorithm was applied in the primary care/diabetes clinic cohort, liver biopsy requirement was only 3%, and the agreement among the three steps provided 75% positive predictive value. CONCLUSIONS: Our study validates the algorithm proposed by the EASL in its latest 2021 guidelines for the diagnosis of advanced fibrosis in the setting of NAFLD.

French guidelines on TIPS: Indications and modalities.

Transjugular intrahepatic portosystemic shunt (TIPS) has become essential in the treatment or prevention of portal hypertension-related complications. In the early 1990s, the primary indication was refractory bleeding. It is now proposed for the treatment of ascites for the prevention of bleeding and in patients with vascular diseases of the liver. Thus, there are a growing number of patients being treated with TIPS all over the world. The broadening of indications, the involvement of multiple stakeholders, the need for an accurate selection, the positioning in relation to transplantation and the lack of standardization in pre-therapeutic assessment, in the procedure itself and in the follow-up have led the board of the French Association for the Study of the Liver to establish recommendations.

Low alcohol consumption influences outcomes in individuals with alcohol-related compensated cirrhosis in a French multicenter cohort.

BACKGROUND & AIMS: The harmful impact of heavy alcohol consumption and recurrence in patients with alcohol-related cirrhosis is long-established, although this is based on old studies. However, the drivers of long-term outcome still need to be clearly investigated. METHOD: All patients with biopsy-proven compensated alcohol-related cirrhosis included in the CIRRAL cohort (22 centers) were prospectively studied. Prognostic variables of survival and liver event-free survival were assessed using multivariable Cox models with stepwise selection. The prognostic impact of alcohol recurrence during follow-up (computed in glass-years in the same way as pack-years for tobacco) was assessed using a time-dependent covariable. RESULTS: From 2010 to 2016, 650 patients were included. The median age at baseline was 58.4 years, 67.4% were men and the median BMI was 27.8 kg/m2, 63.8% had a history of liver decompensation, and 70.2% had discontinued alcohol. At 5 years, recurrence occurred in 30.9% of abstinent patients and this risk was higher in patients with a history of drug abuse and in those with shorter alcohol discontinuation times. Median survival was 97 months. Age, alcohol consumption at baseline, platelet count and Child-Pugh score >5 were associated with overall and liver event-free survival on multivariate analysis. Alcohol consumption of more than 25 glass-years during follow-up was independently associated with lower survival and with a trend toward lower liver event-free survival, with the risk increasing from 1 glass-year, though not significantly. Simon & Makuch plots confirm the benefit of no alcohol consumption (<1 glass/week) on both outcomes and the dose-dependent impact of alcohol over time. CONCLUSION: This prospective study in patients with compensated alcohol-related cirrhosis identifies factors predictive of alcohol recurrence during follow-up and shows that moderate alcohol consumption during follow-up negatively impacts outcomes. Patients with alcohol-related cirrhosis should be advised to completely stop drinking alcohol. REGISTRATION: CIRRAL (NCT01213927) cohort was registered at ClinicalTrials.gov and the full protocol is available at the following link: https://clinicaltrials.gov/ct2/show/NCT01213927. IMPACT AND IMPLICATIONS: In patients with alcohol-related cirrhosis, data are lacking about the impact of the amount of alcohol consumed on both survival and liver-related events. The present study based on the CIRRAL cohort demonstrates that alcohol recurrence occurs in more than 30% of patients with compensated cirrhosis and that even a moderate recurrence strongly influences outcomes. Patients with compensated alcohol-related cirrhosis should be advised to completely discontinue alcohol consumption, even in small amounts, as the present study shows that no alcohol consumption can be regarded as safe when cirrhosis has developed.

Impact of Type 2 Diabetes on the Accuracy of Noninvasive Tests of Liver Fibrosis With Resulting Clinical Implications.

BACKGROUND & AIMS: Noninvasive tests (NITs) of liver fibrosis have been suggested to be less accurate in type 2 diabetes mellitus (T2DM). We aimed to compare the accuracy of 6 NITs between patients with or without T2DM, explain any differences, and adapt diagnostic algorithms for clinical practice accordingly. METHODS: We included 1051 patients with nonalcoholic fatty liver disease with liver biopsy, blood fibrosis tests (Nonalcoholic Fatty Liver Disease Fibrosis Score, FIB4, Fibrotest, FibroMeter), vibration-controlled transient elastography (VCTE), and the combinatory elasto-blood test FibroMeterVCTE. The study endpoint was advanced fibrosis on liver biopsy. RESULTS: NIT areas under the receiver operating characteristic curve were significantly lower in patients with T2DM, mostly because of a decrease in specificity. For FIB4, this decrease in specificity was only related to the higher age of patients with T2DM enrolled. For Fibrotest, FibroMeter, and FibroMeterVCTE, the decrease in specificity was related to age but also to higher alpha2-macroglobulin level, which is known to increase in T2DM. Sensitivity was unaffected by T2DM, but it masked a doubled raw number of false negatives because of the 2-fold higher prevalence of advanced fibrosis in that setting. The sequential algorithm FIB4-vibration-controlled transient elastography had 90.3% accuracy in patients without T2DM vs 79.0% in those with (P < .001). Algorithms using first-line specialized tests maintained a low rate of false negatives and false positives in T2DM. CONCLUSIONS: The decrease in NIT accuracy observed in T2DM is partly biased by the different characteristics of the groups studied, but also linked to T2DM itself through modification of the levels of some NIT biomarkers. Specialized tests should be used first-line to diagnose advanced liver fibrosis in T2DM.

Efficacy and safety of intravenous bevacizumab on severe bleeding associated with hemorrhagic hereditary telangiectasia: A national, randomized multicenter trial.

BACKGROUND: Bevacizumab-a humanized monoclonal antibody-has been widely used to treat patients with hereditary hemorrhagic telangiectasia (HHT), but no randomized trial has yet been conducted. METHODS: This study is a double-blind multicenter randomized phase 2 trial with a 1:1 active-treatment-to-placebo ratio. We included patients over the age of 18 with a confirmed diagnosis and the need for at least four red blood cell (RBC) units transfused in the 3 months before study enrollment. Bevacizumab was administered at a dose of 5 mg/kg every 14 days with a total of six injections. The primary efficacy criterion was a decrease of at least 50% in the cumulative number of RBC units transfused in a 3-month period before and after treatment. RESULTS: A total of 24 patients (12 in each group) were included and randomized at 4 different centers. In intention-to-treat analysis, 63.6% of patients (7/11) in the bevacizumab group versus 33.3% of patients (4/12) in the placebo group decreased the number of blood transfusions by at least 50% (p = 0.22). Hemoglobin levels significantly improved at 6 months in the bevacizumab versus placebo group (p = 0.02). The pharmacokinetics study revealed that patients with high exposure to bevacizumab had a significant decrease in RBC transfusions (p = 0.03). Fifty-nine adverse events were observed, 34 in the placebo arm versus 25 in the bevacizumab arm. CONCLUSION: Though the present trial was underpowered, patients with HHT receiving bevacizumab required numerically fewer red blood cell transfusions than those receiving placebo, particularly those with high exposure.

Diagnosis and management of hepatic encephalopathy: The French recommendations.

Hepatic encephalopathy (HE) is a frequent and severe complication of liver disease with poor patient outcomes. However, it is a poorly understood complication, with no consensus for diagnosis. Therefore, HE is often underdiagnosed. Differential diagnosis may be cumbersome because of non-specific symptoms, such as confusion, cognitive disorders, the aetiological factors of cirrhosis and comorbidities, which are often observed in cirrhotic patients. Therefore, an overt or covert form of HE should be systematically investigated. Advice is provided to drive patient work-up. Effective treatments are available to prevent or treat HE bouts, but the issue of single or combination therapy has not been resolved. Transjugular intrahepatic portosystemic shunt (TIPS) placement largely improved the prognosis of cirrhotic patients, but HE occurrence of HE is often a fear, even when post-TIPS HE can be avoided by a careful selection of patients and preventive treatment. HE is an indication of liver transplantation. However, its reversibility post-transplantation and the consequences of transplantation in patients with other causes of neurological disorders remain controversial, which supports the performance of an extensive work-up in expert centres for this subset of patients. The present guidelines assist clinicians in the diagnosis of the overt or covert form of HE to implement curative and preventive treatments and clarify which patients require referral to expert centres for consideration for liver transplantation. These guidelines are very clinically oriented and address different frequent clinical issues to help physicians make bedside decisions.

Effect of Prophylactic Antibiotics on Mortality in Severe Alcohol-Related Hepatitis: A Randomized Clinical Trial.

Importance: The benefits of prophylactic antibiotics for hospitalized patients with severe alcohol-related hepatitis are unclear. Objective: To determine the efficacy of amoxicillin-clavulanate, compared with placebo, on mortality in patients hospitalized with severe alcohol-related hepatitis and treated with prednisolone. Design, Setting, and Participants: Multicenter, randomized, double-blind clinical trial among patients with biopsy-proven severe alcohol-related hepatitis (Maddrey function score ≥32 and Model for End-stage Liver Disease [MELD] score ≥21) from June 13, 2015, to May 24, 2019, in 25 centers in France and Belgium. All patients were followed up for 180 days. Final follow-up occurred on November 19, 2019. Intervention: Patients were randomly assigned (1:1 allocation) to receive prednisolone combined with amoxicillin-clavulanate (n = 145) or prednisolone combined with placebo (n = 147). Main Outcome and Measures: The primary outcome was all-cause mortality at 60 days. Secondary outcomes were all-cause mortality at 90 and 180 days; incidence of infection, incidence of hepatorenal syndrome, and proportion of participants with a MELD score less than 17 at 60 days; and proportion of patients with a Lille score less than 0.45 at 7 days. Results: Among 292 randomized patients (mean age, 52.8 [SD, 9.2] years; 80 [27.4%] women) 284 (97%) were analyzed. There was no significant difference in 60-day mortality between participants randomized to amoxicillin-clavulanate and those randomized to placebo (17.3% in the amoxicillin-clavulanate group and 21.3% in the placebo group [P = .33]; between-group difference, -4.7% [95% CI, -14.0% to 4.7%]; hazard ratio, 0.77 [95% CI, 0.45-1.31]). Infection rates at 60 days were significantly lower in the amoxicillin-clavulanate group (29.7% vs 41.5%; mean difference, -11.8% [95% CI, -23.0% to -0.7%]; subhazard ratio, 0.62; [95% CI, 0.41-0.91]; P = .02). There were no significant differences in any of the remaining 3 secondary outcomes. The most common serious adverse events were related to liver failure (25 in the amoxicillin-clavulanate group and 20 in the placebo group), infections (23 in the amoxicillin-clavulanate group and 46 in the placebo group), and gastrointestinal disorders (15 in the amoxicillin-clavulanate group and 21 in the placebo group). Conclusion and Relevance: In patients hospitalized with severe alcohol-related hepatitis, amoxicillin-clavulanate combined with prednisolone did not improve 2-month survival compared with prednisolone alone. These results do not support prophylactic antibiotics to improve survival in patients hospitalized with severe alcohol-related hepatitis.

Transient Elastography Accurately Screens for Compensated Advanced Chronic Liver Disease in Patients With Ongoing or Recent Alcohol Withdrawal.

BACKGROUND & AIMS: Liver stiffness measurement by transient elastography (TE) is a promising method for staging fibrosis in alcohol-related liver disease, but uncertainties remain regarding the influence of alcohol consumption and thus the ideal timing for TE performance. We evaluated the performance of TE compared with liver biopsy to exclude compensated advanced chronic liver disease (cACLD) in patients hospitalized for alcohol detoxification. METHODS: Patients were recruited prospectively at 6 in-patient addiction centers in France. Eligible patients had increased aspartate aminotransferase levels, and no history or signs of overt cirrhosis. TE, histology, and biochemistry measurements were obtained within a median of 6 days after alcohol withdrawal. TE and biochemistry were repeated 1 and 2 months later. RESULTS: The study included 259 patients for per-protocol analysis, of whom 45 (17%) had cACLD. TE identified patients with high accuracy at inclusion and at the 1- and 2-month follow-up evaluation, with area under the curve values of 0.96 (95% CIs, 0.94-0.99), 0.96 (95% CIs, 0.92-0.99), and 0.93 (95% CIs, 0.85-1.00), respectively. In 84% of patients, cACLD was ruled out when liver stiffness was less than 10 kPa (negative predictive value, 99% (95% CIs, 98%-100%)) or ruled in when greater than 25 kPa (positive predictive value, 93% (95% CI, 83%-102%)). Algorithms based on aminotransferase levels and/or bilirubin did not add to the diagnostic performance of TE in this period. Among patients with initial liver stiffness of 10 to 25 kPa, more than half of those with no cACLD showed liver stiffness of less than 10 at 1- and 2-month follow-up testing. CONCLUSIONS: TE performed during the first 2 months after alcohol cessation is an excellent method for excluding alcohol-related cACLD. CLINICAL TRIAL NUMBER: NCT01789008.

ABO blood group does not influence Child-Pugh A cirrhosis outcome: An observational study from CIRRAL and ANRS CO12 CIRVIR cohorts.

BACKGROUND AND AIMS: Non-O blood group promotes deep vein thrombosis and liver fibrosis in both general population and hepatitis C. We aimed to evaluate the influence of Non-O group on the outcome of Child-Pugh A cirrhotic patients. METHODS: We used two prospective cohorts of Child-Pugh A cirrhosis due to either alcohol or viral hepatitis. Primary end point was the cumulated incidence of 'Decompensation' at 3 years, defined as the occurrence of ascites , hydrothorax, encephalopathy, gastrointestinal bleeding related to portal hypertension, or bilirubin >45 µmol/L. Secondary end points were the cumulated incidences of (1) 'Disease Progression' including a « decompensation¼ or « the occurrence of one or more parameters ¼ among: prothrombin time (PT) <45%, albumin <28 g/L, Child-Pugh worsening (B or C vs A or B, C vs B), hepatorenal syndrome, and hepato-pulmonary syndrome, (2) other events such as non-malignant portal vein thrombosis (nmPVT), and (3) overall survival. RESULTS: Patients (n = 1789; 59.9% Non-O group; 40.1% group O) were followed during a median of 65.4 months. At 3 years cumulated incidence of Decompensation was 8.3% in Non-O group and 7.2% in group O (P = .27). Cumulated incidence of Disease Progression was 20.7% in Non-O group and 18.9% in group O (P = .26). Cumulated incidence of nmPVT was 2.7% in Non-O group and 2.8% in group O (P = .05). At 3 years overall survival was 92.4% in Non-O group and 93.4% in group O (P = 1). CONCLUSION: Non-O group does not influence disease outcome in Child-Pugh A cirrhotic patients. Clinicals trial number NCT03342170.

The Use of Rifaximin in the Prevention of Overt Hepatic Encephalopathy After Transjugular Intrahepatic Portosystemic Shunt : A Randomized Controlled Trial.

BACKGROUND: The efficacy of rifaximin in the secondary prevention of overt hepatic encephalopathy (HE) is well documented, but its effectiveness in preventing a first episode in patients after transjugular intrahepatic portosystemic shunt (TIPS) has not been established. OBJECTIVE: To determine whether rifaximin prevents overt HE after TIPS compared with placebo. DESIGN: Randomized, double-blind, multicenter, placebo-controlled trial. (ClinicalTrials.gov: NCT02016196). PARTICIPANTS: 197 patients with cirrhosis undergoing TIPS for intractable ascites or prevention of variceal rebleeding. INTERVENTION: Patients were randomly assigned to receive rifaximin (600 mg twice daily) or placebo, beginning 14 days before TIPS and continuing for 168 days after the procedure. MEASUREMENTS: The primary efficacy end point was incidence of overt HE within 168 days after the TIPS procedure. RESULTS: An episode of overt HE occurred in 34% (95% CI, 25% to 44%) of patients in the rifaximin group (n = 93) and 53% (CI, 43% to 63%) in the placebo group (n = 93) during the postprocedure period (odds ratio, 0.48 [CI, 0.27 to 0.87]). Neither the incidence of adverse events nor transplant-free survival was significantly different between the 2 groups. LIMITATIONS: The study's conclusion applies mainly to patients with alcoholic cirrhosis, who made up the study population. The potential benefit of rifaximin 6 months after TIPS and beyond remains to be investigated. CONCLUSION: In patients with cirrhosis treated with TIPS, rifaximin was well tolerated and reduced the risk for overt HE. Rifaximin should therefore be considered for prophylaxis of post-TIPS HE.

Non-selective beta-blockers increase overall and liver mortality in alcoholic cirrhosis with MELD ≥ 12 over 5 years of follow-up.

BACKGROUND & AIMS: Non-cardioselective beta-blocker (NSBB) effects on mortality in cirrhosis are controversial. We evaluated the impact of NSBBs on mortality according to liver severity and mortality cause. METHODS: Two hundred and fifty-eight patients with alcoholic cirrhosis were included in a retroprospective cohort: 129 NSBB-treated and 129 controls. The NSBB group had the following significant baseline differences: higher MELD, more frequent previous gastrointestinal bleeding, large oesophageal varices (OV) and lower heart rate. Propranolol dose was 160 mg/d in 81% of NSBB patients. RESULTS: (i) Liver function: during 5.3 ± 2.6 years of follow-up, MELD progression was higher in NSBB patients: 1 (-1-4) than in controls: 0 (-1-1) (P = .017). (ii) Overall survival: no significant differences were observed between NSBBs and controls (Kaplan-Meier curves: P = .291). In multivariate Cox analysis, baseline MELD interacted with NSBB (P = .011). Thus, the NSBB hazard ratio (HR) was 0.99 (0.50-1.98) in MELD < 12 vs 3.17 (1.19-8.42) in MELD ≥ 12. (iii) Liver survival: NSBB decreased liver survival (Kaplan-Meier: P = .031). In multivariate Cox analysis, baseline MELD interacted with NSBB (P < .001). The NSBB HR was 0.81 (0.30-2.19) in MELD < 12 vs 6.23 (1.94-20.0) in MELD ≥ 12. In competing risk multivariate analysis for liver mortality, the MELD-NSBB interaction was significant (P < .001): the NSBB HR was 1.02 (0.36-2.91) in MELD < 12 vs 9.24 (3.18-26.9) in MELD ≥ 12. 4) Non-liver survival: contrastingly, non-liver survival was increased by NSBBs, especially in MELD ≥ 12 (competing Kaplan-Meier: P = .044). These results were confirmed in propensity risk score (PRS)-matched patients. CONCLUSION: In alcoholic cirrhosis with rather high propranolol doses, overall and liver survival are significantly aggravated when MELD is ≥12.

Comparison of extracellular and hepatobiliary MR contrast agents for the diagnosis of small HCCs.

BACKGROUND & AIMS: The aim of this study was to use a head-to-head nodule comparison to compare the performance of extracellular contrast agent MRI (ECA-MRI) with that of hepatobiliary contrast agent MRI (HBA-MRI) for the non-invasive diagnosis of small hepatocellular carcinomas (HCCs). METHODS: Between August 2014 and October 2017, 171 patients with cirrhosis, each with 1 to 3 nodules measuring 1-3 cm, were enrolled across 8 centers. All patients underwent both an ECA-MRI and an HBA-MRI within a month. A non-invasive diagnosis of HCC was made when a nodule exhibited arterial phase hyper-enhancement (APHE) with washout at the portal venous phase (PVP) and/or delayed phase (DP) for ECA-MRI, or the PVP and/or HB phase (HBP) for HBA-MRI. The gold standard was defined by using a previously published composite algorithm. RESULTS: A total of 225 nodules, of which 153 were HCCs and 72 were not, were included. The sensitivites of both MRI techniques were similar. Specificity was 83.3% (95% CI 72.7-91.1) for ECA-MRI and 68.1% (95% CI 56.0-78.6) for HBA-MRI. In terms of HCC diagnosis on ECA-MRI, 138 nodules had APHE, 84 had washout at PVP, and 104 at DP; on HBA-MRI, 128 nodules had APHE, 71 had washout at PVP, and 99 at HBP. For nodules 2-3 cm in size, sensitivity and specificity were similar between the 2 approaches. For nodules 1-2 cm in size, specificity dropped to 66.1% (95% CI 52.2-78.2) for HBA-MRI vs. 85.7% (95% CI 73.8-93.6) for ECA-MRI. CONCLUSIONS: HBA-MRI specificity is lower than that of ECA-MRI for diagnosing small HCCs in patients with cirrhosis. These results raise the question of the proper use of HBA-MRI in algorithms for the non-invasive diagnosis of small HCCs. LAY SUMMARY: There are 2 magnetic resonance imaging (MRI)-based approaches available for the non-invasive diagnosis of hepatocellular carcinoma (HCC), using either extracellular or hepatobiliary contrast agents. The current results showed that the sensitivity of MRI with hepatobiliary contrast agents was similar to that with extracellular contrast agents, but the specificity was lower. Thus, hepatobiliary contrast agent-based MRI, although detailed in international guidelines, should be used with caution for the non-invasive diagnosis of HCC. CLINICAL TRIAL NUMBER: NCT00848952.

New sequential combinations of non-invasive fibrosis tests provide an accurate diagnosis of advanced fibrosis in NAFLD.

BACKGROUND & AIMS: Advanced liver fibrosis is an important diagnostic target in non-alcoholic fatty liver disease (NAFLD) as it defines the subgroup of patients with impaired prognosis. The non-invasive diagnosis of advanced fibrosis is currently limited by the suboptimal positive predictive value and the grey zone (representing indeterminate diagnosis) of fibrosis tests. Here, we aimed to determine the best combination of non-invasive tests for the diagnosis of advanced fibrosis in NAFLD. METHODS: A total of 938 patients with biopsy-proven NAFLD were randomized 2:1 into derivation and validation sets. All patients underwent liver stiffness measurement with vibration controlled transient elastography (VCTE) and blood fibrosis tests (NAFLD fibrosis score, Fibrosis-4 [FIB4], Fibrotest, Hepascore, FibroMeter). FibroMeterVCTE, which combines VCTE results and FibroMeter markers in a single test, was also calculated in all patients. RESULTS: For the diagnosis of advanced fibrosis, VCTE was significantly more accurate than the blood tests (area under the receiver operating characteristic curve [AUROC]: 0.840 ±â€¯0.013, p ≤0.005). FibroMeter was the most accurate blood test (AUROC: 0.793 ±â€¯0.015, p ≤0.017). The combinatory test FibroMeterVCTE outperformed VCTE and blood tests (AUROC: 0.866 ±â€¯0.012, p ≤0.005). The sequential combination of FIB4 then FibroMeterVCTE (FIB4-FMVCTE algorithm) or VCTE then FibroMeterVCTE (VCTE-FMVCTE algorithm) provided an excellent diagnostic accuracy of 90% for advanced fibrosis, with liver biopsy only required to confirm the diagnosis in 20% of cases. The FIB4-FMVCTE and VCTE-FMVCTE algorithms were significantly more accurate than the pragmatic algorithms currently proposed. CONCLUSION: The sequential combination of fibrosis tests in the FIB4-FMVCTE and VCTE-FMVCTE algorithms provides a highly accurate solution for the diagnosis of advanced fibrosis in NAFLD. These algorithms should now be validated for the diagnosis of advanced liver fibrosis in diabetology or primary care settings. LAY SUMMARY: The evaluation of liver fibrosis is mandatory in non-alcoholic fatty liver disease (NAFLD), as advanced fibrosis identifies the subgroup of patients with impaired prognosis. FibroMeterVCTE is a new fibrosis test combining blood markers and the result of vibration controlled transient elastography (VCTE) into a single diagnostic test. Our results show that FibroMeterVCTE outperforms other blood fibrosis tests and VCTE alone for the diagnosis of advanced fibrosis in a large multi-centric cohort of 938 patients with biopsy-proven NAFLD. Sequential algorithms using a simple blood test or VCTE as a first-line procedure, then FibroMeterVCTE as a second-line test accurately classified 90% of patients.

Criteria to Determine Reliability of Noninvasive Assessment of Liver Fibrosis With Virtual Touch Quantification.

BACKGROUND & AIMS: Virtual Touch Quantification (VTQ) evaluates liver fibrosis in patients with chronic liver diseases by measuring shear wave speed in the liver. We aimed to determine the reliability criteria of VTQ examination. METHODS: We performed a prospective study of 1094 patients with chronic liver disease from November 2009 through October 2016 at Angers University Hospital, and between April 2010 and May 2015 at Bordeaux University Hospital, in France. All patients underwent liver biopsy analysis (reference standard), and VTQ examination was made by experienced operators on the same day, or no more than 3 months before or afterward. Advanced liver fibrosis was defined as fibrosis stage F ≥ 3 according to the scoring system of the Nonalcoholic Steatohepatitis Clinical Research Network, or fibrosis stage F ≥ 2 according to the Metavir scoring system. The diagnostic accuracy of VTQ in detection of advanced fibrosis or cirrhosis was assessed using the area under the receiver operating characteristic (AUROC) and the rate of correctly classified patients. Reliability criteria were defined from the intrinsic characteristics of VTQ examination, which were shown to influence the diagnostic accuracy. RESULTS: VTQ identified patients with advanced fibrosis with an AUROC of 0.773 ± 0.014 and correctly classified 72.0% of patients using a diagnostic cut-off value of 1.37 m/s. VTQ identified patients with cirrhosis with an AUROC value of 0.839 ± 0.014 and correctly classified 78.4% of patients using a cut-off value of 1.87 m/s. The reliability of VTQ decreased with an increasing ratio of interquartile range/median (IQR/M) in patients with intermediate-high VTQ results. We defined 3 reliability categories for VTQ: unreliable (IQR/M ≥0.35 with VTQ result ≥1.37 m/s), reliable (IQR/M ≥0.35 with VTQ result <1.37 m/s or IQR/M 0.15-0.34), and very reliable (IQR/M <0.15). For advanced fibrosis, VTQ correctly classified 57.8% of patients in the unreliable group, 73.7% of patients in the reliable group, and 80.9% of patients in the very reliable group (P < .001); for cirrhosis, these values were 50.0%, 83.4%, and 92.6%, respectively (P < .001). Of the VTQ examinations made, 21.4% were unreliable, 55.0% were reliable, and 23.6% were very reliable. The skin-liver capsule distance was independently associated with an unreliable VTQ examination, which occurred in 52.7% of patients with a distance of 30 mm or more. CONCLUSIONS: In a study to determine the reliability of VTQ findings, compared with results from biopsy analysis, we assigned VTQ examinations to 3 categories (unreliable, reliable, and very reliable). VTQ examinations with IQR/M ≥0.35 and ≥1.37 m/s had very low diagnostic accuracy. Our reliability criteria for liver fibrosis assessment with VTQ will help physicians to accurately evaluate the severity of chronic liver diseases and monitor their progression.

Idarubicin-loaded Beads for Chemoembolization of Hepatocellular Carcinoma: The IDASPHERE II Single-Arm Phase II Trial.

Background A prior in vitro study showed that idarubicin was the most cytotoxic agent for hepatocellular carcinoma (HCC) cell lines. Idarubicin-loaded beads for transarterial chemoembolization (TACE) were previously evaluated for the appropriate dose in a phase I dose-escalation study. Purpose To evaluate objective response rate (ORR), safety, and survival after TACE by using idarubicin-loaded beads for unresectable HCC. Materials and Methods This prospective single-arm phase II study was conducted between January 2015 and January 2017. Participants with unresectable HCC were included in the trial and underwent TACE with idarubicin-eluting beads. The primary end point was 6-month ORR assessed with independent central review by using modified Response Evaluation Criteria in Solid Tumors. Secondary end points were best ORR during the first 6 months, overall survival, progression-free survival, time to progression, and safety. A two-stage Fleming statistical design was used. Results Forty-six study participants (mean age, 71.2 years ± 10.2; six women and 40 men) were included; 44 participants underwent at least one TACE session. The 6-month ORR was 52% (23 of 44). The best ORR achieved was 68% (30 of 44). Fourteen of 44 (32%) participants underwent a curative treatment after TACE. Median progression-free survival, time to progression, and overall survival were 6.6 months, 9.5 months, and 18.6 months, respectively. TACE was discontinued for toxicity in four of 44 (9%) participants. The most frequent grade 3-4 adverse events were elevated aspartate aminotransferase (14 of 44, 32%), elevated γ-glutamyl transpeptidase (eight of 44, 18%), hyperbilirubinemia (seven of 44, 16%), elevated alanine aminotransferase (seven of 44, 16%), and pain (seven of 44, 16%). Conclusion Idarubicin-eluting beads showed a good safety profile and promising objective response rate and time to progression when used as part of a transarterial chemoembolization regimen for unresectable hepatocellular carcinoma. © RSNA, 2019 See also the editorial by Padia in this issue.

Macrotrabecular-massive hepatocellular carcinoma: A distinctive histological subtype with clinical relevance.

We recently identified a histological subtype of hepatocellular carcinoma (HCC), designated as "macrotrabecular-massive" (MTM-HCC) and associated with specific molecular features. In order to assess the clinical relevance of this variant, we investigated its prognostic value in two large series of patients with HCC treated by either surgical resection or radiofrequency ablation (RFA). We retrospectively included 237 HCC surgical samples and 284 HCC liver biopsies from patients treated by surgical resection and RFA, respectively. Histological slides were reviewed by pathologists specialized in liver disease, and the MTM-HCC subtype was defined by the presence of a predominant (>50%) macrotrabecular architecture (more than six cells thick). The main clinical and biological features were recorded at baseline. Clinical endpoints were early and overall recurrence. The MTM-HCC subtype was identified in 12% of the whole cohort (16% of surgically resected samples, 8.5% of liver biopsy samples). It was associated at baseline with known poor prognostic factors (tumor size, alpha-fetoprotein level, satellite nodules, and vascular invasion). Multivariate analysis showed that MTM-HCC subtype was an independent predictor of early and overall recurrence (surgical series: hazard ratio, 3.03; 95% confidence interval, 1.38-6.65; P = 0.006; and 2.76; 1.63-4.67; P < 0.001; RFA series: 2.37; 1.36-4.13; P = 0.002; and 2.19; 1.35-3.54; P = 0.001, respectively). Its prognostic value was retained even after patient stratification according to common clinical, biological, and pathological features of aggressiveness. No other baseline parameter was independently associated with recurrence in the RFA series. CONCLUSION: The MTM-HCC subtype, reliably observed in 12% of patients eligible for curative treatment, represents an aggressive form of HCC that may require more specific therapeutic strategies.

Pregnancy in idiopathic non-cirrhotic portal hypertension: A multicentric study on maternal and fetal management and outcome.

BACKGROUND & AIMS: A total of 15% of patients with idiopathic non-cirrhotic portal hypertension (INCPH) are women of childbearing age. We aimed to determine maternal and fetal outcome of pregnancies occurring in women with INCPH. METHODS: We retrospectively analyzed the charts of women with INCPH followed in the centers of the VALDIG network, having had ≥1 pregnancy during the follow-up of their liver disease. Data are represented as median (interquartile range). RESULTS: A total of 24 pregnancies occurred in 16 women within 24 (5-66) months after INCPH diagnosis. Four women had associated partial portal vein thrombosis before pregnancy. At conception, 2 out of the 16 women had detectable ascites and others were asymptomatic. Out of these 24 pregnancies, there were four miscarriages, one ectopic pregnancy, and one medical termination of pregnancy at 20 weeks of gestation. Out of the 18 other pregnancies reaching 20 weeks of gestation (in 14 patients), there were nine preterm and nine term deliveries. All infants were healthy at delivery, but one died at day 1 of unknown cause and one at day 22 of infectious meningitis; both were preterm. Concerning mothers, two had worsening of ascites, two had variceal bleeding despite non-selective betablockers during pregnancy and one developed a main portal vein thrombosis in early postpartum. Genital bleeding occurred in three patients, including two receiving anticoagulation. All 16 women were alive and asymptomatic after a median follow-up of 27 (9-93) months after last delivery. CONCLUSION: The overall outcome of women with INCPH who become pregnant is favorable despite a significant incidence of complications related to portal hypertension. Fetal outcome is favorable in most pregnancies reaching 20 weeks of gestation. LAY SUMMARY: About 15% of patients with idiopathic non-cirrhotic portal hypertension are women of childbearing age, who can become pregnant. As available reports on pregnancy in these women are scarce and heterogeneous, it is unclear whether or not pregnancy should be contraindicated in this setting. We provide detailed data showing that, regardless of the associated conditions, the overall outcome of women with idiopathic non-cirrhotic portal hypertension becoming pregnant is good despite a significant incidence of complications related to portal hypertension, and that fetal outcome is favorable in most pregnancies reaching 20 weeks of gestation.

Estimate of hepatocellular carcinoma incidence in patients with alcoholic cirrhosis.

BACKGROUND & AIMS: More than 90% of cases of hepatocellular carcinoma (HCC) occur in patients with cirrhosis, of which alcohol is a major cause. The CIRRAL cohort aimed to assess the burden of complications in patients with alcoholic cirrhosis, particularly the occurrence of HCC. METHODS: Patients with biopsy-proven compensated alcoholic cirrhosis were included then prospectively followed. The main endpoint was the incidence of HCC. Secondary outcomes were incidence of hepatic focal lesions, overall survival (OS), liver-related mortality and event-free survival (EFS). RESULTS: From October 2010 to April 2016, 652 patients were included in 22 French and Belgian centers. During follow-up (median 29 months), HCC was diagnosed in 43 patients. With the limitation derived from the uncertainty of consecutive patients' inclusion and from a sizable proportion of dropouts (153/652), the incidence of HCC was 2.9 per 100 patient-years, and one- and two-year cumulative incidences of 1.8% and 5.2%, respectively. Although HCC fulfilled the Milan criteria in 33 cases (77%), only 24 patients (56%) underwent curative treatment. An explorative prognostic analysis showed that age, male gender, baseline alpha-fetoprotein, bilirubin and prothrombin were significantly associated with the risk of HCC occurrence. Among 73 deaths, 61 had a recorded cause and 27 were directly attributable to liver disease. At two years, OS, EFS and cumulative incidences of liver-related deaths were 93% (95% CI 90.5-95.4), 80.3% (95% CI 76.9-83.9), and 3.2% (95% CI 1.6-4.8) respectively. CONCLUSION: This large prospective cohort incompletely representative of the whole population with alcoholic cirrhosis showed: a) an annual incidence of HCC of up to 2.9 per 100 patient-years, suggesting that surveillance might be cost effective in these patients; b) a high proportion of HCC detected within the Milan criteria, but only one-half of detected HCC cases were referred for curative treatments; c) a two-year mortality rate of up to 7%. LAY SUMMARY: Cirrhosis is a risk factor for primary liver cancer, leading to recommendations for periodic screening. However, for alcohol-related liver disease the rational of periodic screening for hepatocellular carcinoma (HCC) is controversial, as registry and databased studies have suggested a low incidence of HCC in these patients and highly competitive mortality rates. In this study, a large cohort of patients with biopsy-proven alcoholic cirrhosis prospectively screened for HCC demonstrated a high annual incidence of HCC (2.9%) and a high percentage of small cancers theoretically eligible for curative treatment. This suggests that patients with liver disease related to alcohol should not be ruled out of screening.

Transjugular Intrahepatic Portosystemic Shunts With Covered Stents Increase Transplant-Free Survival of Patients With Cirrhosis and Recurrent Ascites.

BACKGROUND & AIMS: There is controversy over the ability of transjugular intrahepatic portosystemic shunts (TIPS) to increase survival times of patients with cirrhosis and refractory ascites. The high rate of shunt dysfunction with the use of uncovered stents counteracts the benefits of TIPS. We performed a randomized controlled trial to determine the effects of TIPS with stents covered with polytetrafluoroethylene in these patients. METHODS: We performed a prospective study of 62 patients with cirrhosis and at least 2 large-volume paracenteses within a period of at least 3 weeks; the study was performed at 4 tertiary care centers in France from August 2005 through December 2012. Patients were randomly assigned to groups that received covered TIPS (n = 29) or large-volume paracenteses and albumin as necessary (LVP+A, n = 33). All patients maintained a low-salt diet and were examined at 1 month after the procedure then every 3 months until 1 year. At each visit, liver disease-related complications, treatment modifications, and clinical and biochemical variables needed to calculate Child-Pugh and Model for End-Stage Liver Disease scores were recorded. Doppler ultrasonography was performed at the start of the study and then at 6 and 12 months after the procedure. The primary study end point was survival without a liver transplant for 1 year after the procedure. RESULTS: A higher proportion of patients in the TIPS group (93%) met the primary end point than in the LVP+A group (52%) (P = .003). The total number of paracenteses was 32 in the TIPS group vs 320 in the LVP+A group. Higher proportions of patients in the LVP+A group had portal hypertension-related bleeding (18% vs 0%; P = .01) or hernia-related complications (18% vs 0%; P = .01) than in the TIPS group. Patients in LVP+A group had twice as many days of hospitalization (35 days) as the TIPS group (17 days) (P = .04). The 1-year probability of remaining free of encephalopathy was 65% for each group. CONCLUSIONS: In a randomized trial, we found covered stents for TIPS to increase the proportion of patients with cirrhosis and recurrent ascites who survive transplantation-free for 1 year, compared with patients given repeated LVP+A. These findings support TIPS as the first-line intervention in such patients. ClinicalTrials.gov ID: NCT00222014.
