RESUMEN

BACKGROUND AND AIMS: A recent single-center study reported a significant increase in acute myeloid leukaemia (AML) cases, including mixed-phenotype acute leukaemia (MPAL), after exposure to direct acting agents (DAA). We investigated whether DAA use increased the risk of AML in patients with chronic hepatitis C virus (HCV) infection. METHODS: We conducted a disproportionality analysis of the WHO Pharmacovigilance database Vigibase up to 2020. Queries focused on all DAAs, subclasses, combinations or each DAA separately as well as interferon and ribavirin as negative controls. The primary outcome was AML. Secondary outcomes were AML without MPAL, MPAL, acute lymphoid leukemia (ALL) and acute leukemia (AL, high-level term encompassing AML, ALL, MPAL and unspecified acute leukemia [UAL]). The information component (IC0.25) and proportional reporting ratio (PRR0.25) were computed to assess a potential pharmacovigilance signal. RESULTS: We identified 49 notifications reporting any AL occurrence after anti-HCV treatments from June 1997 to December 2020: 23 (47%) involved a DAA, 24 (49%) interferon and 12 (24%) ribavirin. The DAAs sofosbuvir and ledipasvir were suspected in 74% (n = 17) and 39% (n = 9) of cases. The events reported were AML (n = 22), ALL (n = 11), AML and ALL (n = 1) and UAL (n = 15) and no MPAL. DAA, interferon or ribavirin were not significantly associated with AML, ALL or AL. CONCLUSION: This study did not find any association between DAA exposure and the occurrence of AML. Nevertheless, vigilance should remain, particularly for MPAL, which may not have been well captured in our study because of its rareness and high risk of misclassification.

RESUMEN

BACKGROUND AND AIMS: Gilbert syndrome (GS) is genotypically predetermined by UGT1A1*28 homozygosity in Europeans and is phenotypically defined by hyperbilirubinemia using total bilirubin (TB) cutoff ≥1mg/dL (17 µmol/L). The prevalence of illnesses associated with GS and hypobilirubinemia has never been studied prospectively. As TB varies with UGT1A1*28 genotyping, sex, and age, we propose stratified definitions of TB reference intervals and report the prevalence of illnesses and adjusted 15 years survival. METHODS: UK Biobank with apparently healthy liver participants (middle-aged, n=138,125) were analyzed after the exclusion of of nonhealthy individuals. The stratified TB was classified as GS when TB >90th centile; <10th centile indicated hypobilirubinemia, and between the 10th and 90th centile was normobilirubinemia. We compared the prevalence and survival rates of 54 illnesses using odds ratio (OR), logistic regression, and Cox models adjusted for confounders, and causality by Mendelian randomizations. RESULTS: In women, we identified 10% (7,741/76,809) of GS versus 3.7% (2,819/76,809) using the historical cutoff of ≥1 mg/dL (P<0.0001). When GS and hypobilirubinemia participants were compared with normobilirubinemia, after adjustment and Mendelian randomizations, only cholelithiasis prevalence was significantly higher (OR=1.50; 95% CI [1.3-1.7], P=0.001) in men with GS compared with normobilirubinemia and in causal association with bilirubin (P=0.04). No adjusted survival was significantly associated with GS or hypobilirubinemia. CONCLUSIONS: In middle-aged Europeans, the stratified TB demonstrates a careless GS underestimation in women when using the standard unisex 1 mg/dL cutoff. The prevalence of illnesses is different in GS and hypobilirubinemia as well as survivals before adjusting for confounding factors. With the exception of cholelithiasis in men, these differences were no more significant after adjustment and Mendelian randomization.

RESUMEN

The European Liver and Intestine Transplant Association, ELITA, promoted a Consensus Conference involving 20 experts across the world which generated updated guidelines on HBV prophylaxis in liver transplant candidates and recipients. This study explores the economic impact associated with the implementation of the new ELITA guidelines. To this aim, a condition-specific cohort simulation model has been developed to compare new and historical prophylaxis, including only pharmaceutical cost and using the European perspective. The target population simulated in the model included both prevalent and incident cases, and consisted of 6,133 patients after the first year, that increased to 7,442 and 8,743 patents after 5 and 10 years from its implementation. The ELITA protocols allowed a cost saving of around € 235.65 million after 5 years and € 540.73 million after 10 years; which was mainly due to early HIBG withdrawal either after the first 4 weeks or after the first year post Liver Transplantation (LT) depending on the virological risk at transplantation. Results were confirmed by sensitivity analyses. The money saved by the implementation of the ELITA guidelines would allow healthcare decision makers and budget holders to understand where costs could be reduced and resources re-allocated to different needs.

RESUMEN

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.

RESUMEN

INTRODUCTION: Hepatitis C virus (HCV) may recur after liver transplantation (LT) in the severe form of fibrosing cholestatic hepatitis (FCH). The prognosis dramatically improved by the use of direct acting antivirals (DAAs). The aim of the present study was to describe the change in histological features of FCH after virological eradication. METHODS: From the ANRS CUPILT cohort we included 17 patients who presented FCH and at least two graft biopsies, one before DAA-treatment and one after. A single expert pathologist, blinded for clinical outcome, retrospectively confirmed the diagnosis of FCH and progression of fibrosis. RESULTS: Diagnosis of FCH was made after a median [IQR] 6.0 [3.1-11.8] months after LT, and the median interval between diagnosis and onset of treatment was 1.2 [0.7-6.1] months. The rate of viral eradication was 94.1%. The median delay between the pre-treatment and the treatment biopsies was 12.5 [11.1-20.0] months. Between the end of treatment and the second biopsy, the delay was 5.3 [0.6-7.4] months. Fibrosis stage worsened in 10 patients (58.8%); 6 patients had cirrhosis (35.3%). Chronic rejection appeared in 4 (23.5%) patients. CONCLUSION: Our results suggest that, despite viral eradication in patients presenting FCH after LT, fibrosis progression was observed in half of patients. This should encourage monitoring fibrosis progression despite HCV cure.

RESUMEN

BACKGROUND: After several cases of peculiar hematological malignancies following introduction of new oral anti-hepatitis C virus (HCV) treatments in our recent practice, we aimed to systematically identify all cases of hematological malignancies (HM) in patients with chronic HCV infection and to compare them according to the prescription of oral anti-HCV Direct Acting Antivirals (DAA) treatment or not. MATERIAL/METHODS: In this single-center retrospective observational study, we included all patients with confirmed HM and chronic HCV infection managed between 2010 and 2019 in the Pitié-Salpêtrière hospital, Paris. Non-inclusion criteria were a benign hematological disorder, an HM preceding chronic HCV infection and HCV acute infection. We compared characteristics of patients who received DAA before HM diagnosis to those with no DAA before HM. RESULTS: Over the 10 years, 61 cases of HM among HCV infected patients were identified (female 29%, median age of 58.0 years [IQR 17]). Twenty-one received DAA before the onset of HM (Group DAA+) and 40 did not (Group DAA-) including 22 having received DAA after HM. In the DAA+ group, oral NS5B, NS5A and NS3A inhibitors were used in 90, 76 and 29% respectively. HM developed in the two years following DAA initiation in 76%. Eight (38%) had Non-Hodgkin Lymphoma, 5 (24%) had an Acute Myeloid Leukaemia (AML) including two with a mixed phenotype, 2 each had Hodgkin Lymphoma, Multiple Myeloma or a myeloproliferative disorder and one each had a chronic Lymphocytic Leukaemia or AL Amyloidosis. In the Group DAA-, HM were NHL in 20(50%) patients, Myeloproliferative neoplasms in 7 (17%), Multiple Myeloma in 5, Hodgkin Lymphoma in 3, Myelodysplastic syndrome and AML in 2 (5%) each and Acute Lymphoblastic Leukaemia in one. No significant difference between the groups DAA + and - was found according to age, sex, HCV genotype, viral load, co-infection or type and exposition of previous HCV treatments. AML, liver transplantation and cirrhosis were significantly more frequent in the DAA+ group (p = 0.020, 0.045 and 0.032, respectively). CONCLUSION: AML seemed more frequent after using DAA treatments, notably in severe HCV patients including cirrhotic and/or liver transplanted patients. A multicentric observational study is ongoing to confirm and explore the results.

RESUMEN

We report a rare and very late case of de novo cholangiocarcinoma in a patient transplanted for primary sclerosing cholangitis. An exhaustive analysis of the literature and of our case highlight the very poor prognosis of this type of tumor due to the delay in diagnosis and the potential value of a six-monthly MRI surveillance as soon as cholangitis recurs, but also in the presence of chronic digestive inflammation, whatever the mechanism.

RESUMEN

BACKGROUND: Direct-acting antiviral (DAA) agents for the treatment of hepatitis C virus (HCV) infection have been proven safe and effective in cirrhotic patients awaiting liver transplantation (LT). However, in the long term, data remain minimal regarding the clinical impact of viral eradication on patients listed for decompensated cirrhosis or hepatocellular carcinoma (HCC). We aimed to elucidate the clinical outcomes of patients regarding delisting and the evolution of HCC during the long-term follow-up. METHODS: An observational, multicenter, retrospective analysis was carried out on prospectively collected data from HCV-positive patients treated with an interferon-free regimen while awaiting LT in 18 French hospitals. RESULTS: A total of 179 patients were included in the study. The indication for LT was HCC in 104 (58.1%) patients and cirrhosis in 75 (41.9%) patients. The sustained virological response was 84.4% and the treatment was well tolerated. At five years, among 75 patients with cirrhosis treated for HCV, 19 (25.3%) were delisted following improvement after treatment. Predictive factors for delisting highlighted an absence of ascites, MELD score ≤ 15, and Child-Pugh score ≤ 7. No patients with refractory ascites were delisted. Among patients with HCC, 82 (78.9%) were transplanted. The drop-out rate was low (6.7%) and few recurrences of HCC after LT were observed. CONCLUSIONS: DAAs are safe and effective in patients awaiting LT for cirrhosis or HCC. A quarter of patients with cirrhosis can be delisted because of clinical improvement. Predictive factors for delisting, as a result of improvement, may assist prescribers, before initiating HCV infection therapy in the long-term perspective.

RESUMEN

BACKGROUND: Prophylaxis of HBV recurrence is critical after liver transplantation in HBV patients. Despite new prophylactic schemes, most European LT centres persist on a conservative approach combining hepatitis B immunoglobulin (HBIG) and nucleos(t)ides analogues (NA). AIM: This setting prompted the European Liver Intestine Transplantation Association (ELITA) to look for a consensus on the prevention of HBV recurrence. METHODS: Based on a 4-round Delphi process, ELITA investigated 16 research questions and established 50 recommendations. RESULTS: Prophylaxis should be driven according to 3 simplified risk groups: Low and high virological risk patients, with undetectable and detectable HBV DNA pre-LT, respectively, and special populations (HDV, HCC, poorly adherent patients). In low-risk patients, short-term (4 weeks) combination of third-generation NA+ HBIG, or third generation NA monotherapy can be considered as prophylactic options. In high-risk patients, HBIG can be discontinued once HBV DNA undetectable. Combined therapy for 1 year is advised. HBV-HCC patients should be treated according to their virological risk. In HDV/HBV patients, indefinite dual prophylaxis remains the gold standard. Full withdrawal of HBV prophylaxis following or not HBV vaccination should only be attempted in the setting of clinical trials. Organs from HBsAg+ve donors may be considered after assessment of risks, benefits, and patient consent. They should not be used if HDV is present. In poorly adherent patients, dual long-term prophylaxis is recommended. Budget impact analysis should be taken into account to drive prophylactic regimen. CONCLUSIONS: These ELITA recommendations should stimulate a more rational and homogeneous approach to HBV prophylaxis across LT programs.

RESUMEN

Heart failure and liver disease often coexist because of systemic disorders and diseases that affect both organs as well as complex cardio-hepatic interactions. Heart failure can cause acute or chronic liver injury due to ischaemia and passive venous congestion, respectively. Congestive hepatopathy is frequently observed in patients with congenital heart disease and after the Fontan procedure, but also in older patients with chronic heart failure. As congestive hepatopathy can evolve into cirrhosis and hepatocellular carcinoma, screening for liver injury should be performed in patients with chronic cardiac diseases and after Fontan surgery. Fibrosis starts in the centro-lobular zone and will extend progressively to the portal area. Chronic liver injury can be reversible if heart function improves. However, in the case of terminal heart failure, uncontrolled by medical resources or by assistive device support, the combination of heart and liver transplants must be discussed in patients with chronic advanced liver fibrosis. In this review of the literature, we will focus on congestive hepatopathy and its complications, such as liver fibrosis and hepatocellular carcinoma, with the aim of improving the management and surveillance of patients experiencing these complications.

RESUMEN

BACKGROUND: After liver transplantation (LT),de novo malignancies are one of the leading causes of late mortality. The aim of the present retrospective study was to identify the risk factors of de novo malignancies in a large cohort of LT recipients in France, using Fine and Gray competing risks regression analysis. METHODS: The study population consisted in 11004 adults transplanted between 2000 and 2013, who had no history of pre-transplant malignancy, except primary liver tumor. A Cox model adapted to the identification of prognostic factors (competitive risks) was used. RESULTS: From the entire cohort, one (or more)de novo malignancy was reported in 1480 L T recipients (13.45%). The probability to develop a de novo malignancy after LT was 2.07% at 1 year, 13.30% at 5 years, and 28.01% at 10 years. Of the known reported malignancies, the most common malignancies were hematological malignancy (22.36%), non-melanoma skin cancer (19.53%) and lung cancer (12.36%). According to Fine and Gray competing risks regression multivariate analysis, were significant risk factors for post-LT de novo malignancy: recipient age (Subdistribution Hazard Ratio (SHR) = 1.03 95%CI 1.03-1.04), male gender (SHR = 1.45 95%CI 1.27-1.67), non-living donor (SHR = 1.67 95%CI 1.14-2.38), a first LT (SHR = 1.35 95%CI 1.09-1.69) and the type of initial liver disease (alcohol-related liver disease (SHR = 1.63 95%CI 1.22-2.17), primary sclerosing cholangitis (SHR = 1.98 95%CI 1.34-2.91), and primary liver tumor (SHR = 1.88 95%CI 1.41-2.54)). Initial immunosuppressive regimen had no significant impact. CONCLUSION: The present study confirms that LT recipient characteristics are associated with the risk ofde novo malignancy and this underlines the need for personalized screening in order to improve survival.

RESUMEN

BACKGROUND & AIMS: Histological classifications used to diagnose/stage non-alcoholic fatty liver disease (NAFLD) are based on morphology, with undetermined clinical correlates and relevance. We assessed the clinical relevance of the fatty liver inhibition of progression (FLIP) algorithm and the steatosis, activity, and fibrosis (SAF) scoring system. METHODS: One hundred and forty consecutive patients with suspected NAFLD and a separate validation cohort of 78 patients enrolled in a therapeutic trial, all with central reading of liver biopsy, were included. FLIP and SAF were used to categorize patients with non-alcoholic steatohepatitis (NASH), non-NASH NAFLD (NAFL), or non-NAFLD. The SAF activity score assessed hepatocyte ballooning and lobular inflammation; a histologically severe disease was defined as a SAF activity score of ≥3 and/or bridging fibrosis or cirrhosis. Clinical, biochemical, and metabolic data were analyzed in relation to histology. RESULTS: Patients with NASH according to the FLIP algorithm had a clinical profile distinct from those with NAFL, with a higher prevalence of metabolic risk factors (increased body mass index [BMI], central obesity, serum glucose, and glycated hemoglobin), more severe insulin resistance (fasting insulin and homeostasis model assessment for insulin resistance [HOMA-IR] values), and higher levels of aminotransferases. Similar findings were documented for patients with severe disease vs. those without. Positive linear trends existed between NASH or severe disease and increasing BMI and HOMA-IR. There was a strong association between liver fibrosis and NASH or SAF-defined scores of activity. Patients with either significant or bridging fibrosis overwhelmingly had NASH, and bridging fibrosis most often coexisted with severe activity. CONCLUSIONS: The FLIP algorithm/SAF score, although based on purely morphological grounds, are clinically relevant, as they identify patients with distinct clinical and biological profiles of disease severity. Disease activity in NAFLD is associated with fibrosis severity. LAY SUMMARY: The examination of liver tissue under the microscope (histology) serves to define the type and severity of non-alcoholic fatty liver disease morphologically, and is also used to determine improvement in therapeutic or natural history clinical trials. The FLIP algorithm/SAF classification is a new histological classification well validated on morphological but not clinical grounds. Here, we demonstrate that different disease categories defined by the FLIP/SAF classification correspond to entities of different clinical and biological severity. We also show a strong association between the activity of steatohepatitis (defined histologically) and the amount of fibrotic scar.

RESUMEN

BACKGROUND: Ribavirin is currently recommended for treating chronic hepatitis E virus (HEV) infection. This retrospective European multicenter study aimed to assess the sustained virological response (SVR) in a large cohort of solid organ transplant (SOT) recipients with chronic HEV infection treated with ribavirin monotherapy (N = 255), to identify the predictive factors for SVR, and to evaluate the impact of HEV RNA mutations on virological response. METHODS: Data from 255 SOT recipients with chronic HEV infection from 30 European centers were analyzed. Ribavirin was given at the median dose of 600 (range, 29-1200) mg/day (mean, 8.6 ± 3.6 mg/kg/day) for a median duration of 3 (range, 0.25-18) months. RESULTS: After a first course of ribavirin, the SVR rate was 81.2%. It increased to 89.8% when some patients were offered a second course of ribavirin. An increased lymphocyte count at the initiation of therapy was a predictive factor for SVR, while poor hematological tolerance of ribavirin requiring its dose reduction (28%) and blood transfusion (15.7%) were associated with more relapse after ribavirin cessation. Pretreatment HEV polymerase mutations and de novo mutations under ribavirin did not have a negative impact on HEV clearance. Anemia was the main adverse event. CONCLUSIONS: This large-scale retrospective study confirms that ribavirin is highly efficient for treating chronic HEV infection in SOT recipients and shows that the predominant HEV RNA polymerase mutations found in this study do not affect the rate of HEV clearance.This large-scale retrospective study that included 255 solid organ transplant recipients confirms that ribavirin is highly efficient for treating chronic hepatitis E virus (HEV) infection and shows that HEV RNA polymerase mutations do not play a role in HEV clearance.

RESUMEN

Various types of liver impairment have been described in patients with end-stage heart failure who are awaiting heart transplantation. The liver impairment may be severe, characterized by a high model for end-stage liver disease (MELD) Score and/or the presence of ascites, both of which are associated with a high risk of failure after single heart transplantation. A liver function assessment is therefore necessary before registration on the heart transplant list, moreover in case of long-developing heart failure, such as with congenital heart disease or in the presence of risk factors for chronic liver disease including excessive alcohol consumption, metabolic syndrome or chronic viral hepatitis B or C. In these instances, screening for cirrhosis with liver biopsy and for hepatocellular carcinoma through imaging must be systematic and when present, the indication for combined heart-liver transplantation must be considered. Its benefits, however, in case of liver failure with a high MELD score or multi-organ failure remains to be demonstrated. An exception in which the liver shows no morphological or functional alteration is with familial amyloid neuropathy, during which moderate to severe heart failure implies surgical treatment consisting of a liver or even heart-liver transplantation. These must be done early and are mainly contraindicated according to the level of neurological damage.

RESUMEN

More data on resistance of HCV genotype (GT) 3 and 4 to direct-acting antivirals (DAAs) are still needed. Here we investigated the presence of resistance-associated substitutions (RASs) pre- and post-treatment and their emergence under DAAs in HCV GT3- and GT4-infected patients failing DAA regimens by next-generation sequencing (NGS). Sanger sequencing and NGS were performed on NS5B and NS5A in plasma samples prior to and post treatment of 13 patients. Positions implicated in resistance to anti-NS5A and anti-NS5B in the literature were analysed. No baseline RASs was detected in NS5B but one GT4r virus developed the mutation S282T at failure. In NS5A, pre-existing RASs or polymorphisms were detected in viruses of 6/10 patients (L28M for a GT4a, M28V for a GT4r, L30R for a GT4a, 2 GT4d and 1 GT4r, and T58P for a GT4d) by Sanger sequencing and in viruses of 7/10 patients by NGS. Additional baseline minority substitutions detected by NGS were Y93H in a GT3a, L28M in a GT4a and GT4d, and L28F in a GT4d virus. At failure, these substitutions were found at a frequency of 100%. Y93H was detected alone at baseline, whilst L28M and L28F were accompanied by polymorphisms L30R or L30R + T58P. Use of NGS in patients failing DAAs and infected by HCV GT3 and GT4 revealed the emergence of specific patterns of substitutions in NS5A and NS5B, in particular substitutions at position 28 in NS5A in GT4 virus, highlighting the need to list these substitutions in guidelines for resistance interpretation.

RESUMEN

BACKGROUND: No blood test has been shown to be effective in the prediction of primary liver cancer in patients without cirrhosis. AIM: To construct and internally validate two sequential tests for early prediction of liver cancer. These tests enable an algorithm which could improve the performance of the standard surveillance protocol recommended (imaging with or without AFP), limited to patients with cirrhosis. METHODS: We performed a retrospective analysis in prospectively collected specimens from an ongoing cohort. We designed an early sensitive high-risk test (LCR1) that combined (using Cox model) hepatoprotective proteins (apolipoproteinA1, haptoglobin) with known risk factors (gender, age, gammaglutamyltranspeptidase), and a marker of fibrosis (alpha2-macroglobulin). To increase the specificity, we then combined (LCR2) these components with alpha-fetoprotein. RESULTS: A total of 9892 patients, 85.9% without cirrhosis, were followed up for 5.9 years [IQR: 4.3-9.4]. LCR1 and LCR2 time-dependent AUROCs were not different in construction and validation randomised subsets. Among 2027 patients with high-LCR1 then high-LCR2, 167 cancers (113 with cirrhosis, 54 without cirrhosis) were detected, that is 12 patients needed to screen one cancer. The negative predictive value was 99.5% (95% CI 99.0-99.7) in the 2026 not screened patients (11 cancers without cirrhosis) higher than the standard surveillance, which detected 113 cancers in 755 patients screened, that is seven patients needed to screen one cancer, but with a lower negative predictive value 98.0% (97.5-98.5; Z = 4.3; P < 0.001) in 3298 not screened patients (42 cancers without cirrhosis). CONCLUSIONS: In patients with chronic liver disease the LCR1 and LCR2 tests identify those with a high risk of liver cancer, including in those without cirrhosis. NCT01927133.

RESUMEN

BACKGROUND: Although the FibroTest has been validated as a biomarker to determine the stage of fibrosis in non-alcoholic fatty liver disease (NAFLD) with results similar to those in chronic hepatitis C (CHC), B (CHB), and alcoholic liver disease (ALD), it has not yet been confirmed for the prediction of liver-related death. AIM: To validate the 10-year prognostic value of FibroTest in NAFLD for the prediction of liver-related death. METHOD: Patients in the prospective FibroFrance cohort who underwent a FibroTest between 1997 and 2012 were pre-included. Mortality status was obtained from physicians, hospitals or the national register. Survival analyses were based on univariate (Kaplan-Meier, log rank, AUROC) and multivariate Cox risk ratio taking into account age, sex and response to anti-viral treatment as covariates. The comparator was the performance of the FibroTest in CHC, the most validated population. RESULTS: 7082 patients were included; 1079, 3449, 2051, and 503 with NAFLD, CHC, CHB, and ALD, respectively. Median (range) follow-up was 6.0 years (0.1-19.3). Ten year survival (95% CI) without liver-related death in patients with NAFLD was 0.956 (0.940-0.971; 38 events) and 0.832 (0.818-0.847; 226 events; P = 0.004) in CHC. The prognostic value (AUROC / Cox risk ratio) of FibroTest in patients with NAFLD was 0.941 (0.905-0.978)/1638 (342-7839) and even higher than in patients with CHC 0.875 (0.849-0.901; P = 0.01)/2657 (993-6586). CONCLUSIONS: The FibroTest has a high prognostic value in NAFLD for the prediction of liver-related death. (ClinicalTrials.gov number, NCT01927133).
