RESUMEN

BACKGROUND: Portal hypertension (PHT) often complicates hepatocellular carcinoma (HCC) treatment and prognosis. We aimed to assess PHT's impact on AtezoBev outcomes and identify predictors of acute variceal bleeding (AVB) and clinical ascites occurrence. METHODS: A prospective cohort of 200 HCC patients treated with AtezoBev was studied alongside a retrospective cohort of 123 patients treated with Sorafenib. We assessed factors influencing progression-free survival (PFS), overall survival (OS), AVB and clinical ascites development, focusing on PHT parameters, and comparing outcomes within and between the two cohorts (time-dependent Cox model and adjusted survival curves). RESULTS: Among the AtezoBev cohort, 10% experienced AVB, 24% had high-risk esophageal varices (EV) and 46% vascular invasion. Median PFS and OS in the AtezoBev cohort was 5.13 and 12.2 months. AVB (HR=1.81;[95%CI:1.03-3.17]) and clinical ascites occurrence (HR=2.29;[95%CI:1.52-3.45]) were independently associated with mortality. AVB incidence was 12% at 12 months in AtezoBev patients and EV, history of AVB<6months and vascular invasion were independently associated with AVB. The Sorafenib cohort had shorter median PFS and OS, with similar AVB incidence and only EV were associated with AVB. CONCLUSIONS: PHT-related events significantly affect not only liver decompensation but also OS in AtezoBev-treated patients. We suggest a more widespread use of NSBB to prevent liver decompensation, with intensified prophylaxis for high-risk patients.

RESUMEN

BACKGROUND AND AIMS: A previous individual patient data meta-analysis (IPD-MA) showed that compared with drugs+endoscopy, the placement of transjugular portosystemic shunt within 72 hours of admission (pre-emptive transjugular intrahepatic portosystemic shunt: p-TIPS) increases the survival of high-risk patients (Child-Pugh B+ active bleeding and Child-Pugh C<14 points) with cirrhosis and acute variceal bleeding. However, the previous IPD-MA was not a two-stage meta-analysis, did not consider the potential risk of selection bias of observational studies, and did not include the most recent randomized clinical trial. We performed an updated and revised IPD-MA to reassess the efficacy of p-TIPS, addressing all previous issues. APPROACH AND RESULTS: We included all studies from the previous IPD-MA and searched for other possible eligible publications until September 2022. We performed a two-stage IPD-MA of data from 8 studies (4 randomized clinical trials and 4 observational). In addition, we performed a sensitivity analysis excluding those patients dying up to the first 72 hours after admission in the Drugs+Endoscopy arms of the 4 observational studies. The primary end point was the effects of p-TIPS versus Drugs+Endoscopy on 1-year survival.We identified 1389 patients (342 p-TIPS and 1047 Drugs+Endoscopy). The two-stage IPD-MA showed that p-TIPS significantly reduced the mortality in the overall population (HR=0·43, 95% CI: 0.32-0.60, p <0.001. This effect was observed in both subgroups of patients with Child-Pugh. The sensitivity analysis confirmed the survival benefit of p-TIPS. CONCLUSIONS: The updated two-stage IPD-MA confirms the significant survival advantage of p-TIPS in high-risk patients with cirrhosis and acute variceal bleeding. As a result, we recommend p-TIPS as the preferred first-choice treatment for these patients.

RESUMEN

BACKGROUND: Baveno VI and VII criteria are used in patients with cirrhosis to rule out large size oesophageal varices (EV) and rule in/out clinically significant portal hypertension (CSPH). AIM: To evaluate their diagnostic performance in these patients. METHODS: We retrospectively included all patients with Child-Pugh A cirrhosis and HCC who had endoscopy, liver stiffness measurement (LSM) and platelet count within 6 months. They were classified according to the BCLC stage. Favourable Baveno VI criteria were defined by LSM < 20 kPa and platelets > 150 G/L (to rule out large EV), favourable Baveno VII criteria if LSM ≤ 15 kPa and platelets ≥ 150 G/L (to rule out CSPH, which was defined by a HVPG ≥ 10 mm Hg. RESULTS: We included 185 patients; 46% were BCLC-0/A, 28% BCLC-B and 26% BCLC-C. EV were present in 44% (23% large), and HVPG ≥ 10 mm Hg in 42% (mean 8 mm Hg). In patients with favourable Baveno VI criteria, 8% of the whole cohort (Se 93%, NPV 92%), 11% of BCLC-0-A (Se 89%, NPV 89%) and 10.0% of BCLC-C patients (Se 91%, NPV 90%) had large EV. Among patients with HVPG < 10 mm Hg, 6% had large EV and 17% small. CSPH was present in 23% of patients with favourable Baveno VII criteria among the whole cohort, and in 25% of those with BCLC-0/A. The specificity of LSM ≥ 25 kPa to rule in CSPH was 48%. CONCLUSIONS: Favourable Baveno VI criteria are not appropriate to rule out the presence of high-risk EV, or Baveno VII criteria to rule CSPH in/out in patients with HCC.

RESUMEN

Despite the slow, progressive nature of NAFLD, the number of patients with NAFLD-related cirrhosis has significantly increased. Although the management of patients with cirrhosis is constantly evolving, improving the prognosis of patients with NAFLD-related cirrhosis is a challenge because it is situated at the crossroads between the liver, the metabolic, and the cardiovascular diseases. Therefore, the therapeutic interventions should not only target the liver but also the associated cardiometabolic conditions and should be adapted accordingly. The objective of the current review is to critically discuss the particularities in the management of patients with NAFLD-related cirrhosis. We relied on the recommendations of scientific societies and discussed them in the specific context of NAFLD cirrhosis and the surrounding cardiometabolic milieu. Herein, we covered the following aspects: (1) the weight loss strategies through lifestyle interventions to avoid sarcopenia and improve portal hypertension; (2) the optimal control of metabolic comorbidities in particular type 2 diabetes aimed not only to improve cardiovascular morbidity/mortality but also to lower the incidence of cirrhosis-related complications (we discussed various aspects related to the safety of oral antidiabetic drugs in cirrhosis); (3) the challenges in performing bariatric surgery in patients with cirrhosis related to the portal hypertension and the risk of cirrhosis decompensation; (4) the particularities in the diagnosis and management of the portal hypertension and the difficulties in managing patients awaiting for liver transplantation; and (5) the difficulties in developing drugs and conducting clinical trials in patients with NAFLD-related cirrhosis. Moreover, we discussed the emerging options to overcome these obstacles.

RESUMEN

BACKGROUND: Atezolizumab-bevacizumab is the new standard for advanced hepatocellular carcinoma (HCC) but its impact on portal hypertension (PHT) is unknown. We aimed to identify predictive factors of acute variceal bleeding (AVB) and to monitor PHT parameters under treatment. METHODS: We conducted a prospective study including all cirrhotic patients treated with atezolizumab-bevacizumab since 2020. We performed monitoring of PHT using upper endoscopy at inclusion and at 6 months and hepatic venous pressure gradient (HVPG) at inclusion, 3 and 6 months after the beginning of treatment. We also included a retrospective series of patients treated with sorafenib. Time-to-events data were estimated by Kaplan-Meier with the log-rank test, along with Cox models. RESULTS: Forty-three patients treated with atezolizumab-bevacizumab were included (male 79.1%, Child-Pugh A 86%). At baseline, 48.8% were treated with curative anticoagulation, 16.3% already experienced AVB and 25.6% had large oesophageal varices (EV). Sorafenib group characteristics were similar. Vascular invasion was present in 60.5% and median was HVPG 8.5 mm Hg. No significant modification in HVPG and EV size was observed at 6 months in the whole cohort but also when considering vascular invasion and radiological response. 14% presented AVB within a median time of occurrence of 3 months, without bleeding-related death. In multivariate analysis, history of AVB (HR = 10.58, p = .03) was associated with AVB. AVB incidence was higher in atezolizumab-bevacizumab compared to sorafenib group (21% vs. 5% at 1 year, p = .02). CONCLUSIONS: Atezolizumab-bevacizumab treatment was associated with a higher risk of AVB compared to sorafenib. A history of AVB was associated with AVB during follow-up, which questions the use of bevacizumab in this setting.

RESUMEN

BACKGROUND AND AIMS: Apolipoprotein A1 (A1) and haptoglobin (HP) serum levels are associated with the spread and severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We have constructed and validated a multivariable risk calculator (A1HPV6) integrating A1, HP, alpha2-macroglobulin, and gamma glutamyl transferase to improve the performances of virological biomarkers. METHODS: In a prospective observational study of hospitalized patients with nonsevere SARS-CoV-2 infection, A1HPV6 was constructed in 127 patients and validated in 116. The specificity was assessed in 7482 controls representing the general population. The primary diagnostic endpoint was the area under the receiver operating characteristic curve in patients with positive SARS-CoV-2 PCR. The primary prognostic endpoint was the age-and sex-adjusted risk of A1HPV6 to predict patients with WHO-stage > 4 (W > 4) severity. We assessed the kinetics of the A1HPV6 components in a nonhuman primate model (NHP), from baseline to 7 days (D7) after SARS-CoV-2 infection. RESULTS: The area under the receiver operating characteristic curve for A1HPV6 was 0.99 (95% CI 0.97-0.99) in the validation subset, which was not significantly different from that in the construction subset, 0.99 (0.99-0.99; P = .80), like for sensitivity 92% (85-96) vs 94% (88-97; P = .29). A1HPV6 was associated with W > 4, with a significant odds ratio of 1.3 (1.1-1.5; 0.002). In NHP, A1 levels decreased (P < .01) at D2 and normalized at D4; HP levels increased at D2 and peaked at D4. In patients, A1 concentration was very low at D2 vs controls (P < .01) and increased at D14 (P < .01) but was still lower than controls; HP increased at D2 and remained elevated at D14. CONCLUSION: These results validate the diagnostic and prognostic performances of A1HPV6. Similar kinetics of apolipoprotein A1, HP, and alpha-2-macroglobulin were observed in the NHP model.

RESUMEN

BACKGROUND: Combination of liver stiffness measurement and platelets count is a tool to safely rule out varices needing treatment (VNT) in patients with compensated advanced chronic liver disease (cACLD). AIMS: to evaluate 4-year liver-related complications and survival in low-risk patients according to Baveno VI criteria. METHODS: we conducted a monocentric retrospective analysis of prospectively collected data of all consecutive patients, with cirrhosis (LSM≥12.5 kPa) and without previous complication, evaluated between 2012 and 2015. Liver-related complications and survival were compared between 2 groups of patients: favourable (LSM< 20 kPa and platelet count>150.000/mm3) and unfavourable Baveno VI status patients (LSM ≥ 20 kPa or platelet count ≤150.000/mm3). RESULTS: 455 patients with cACLD were analysed. Two hundred patients had favourable Baveno VI criteria, 3.6% with VNT. The 4-year probability of being free of acute decompensation was higher in low-risk patients (94.4 ± 1.8% vs. 85.7%±2.6%, p = 0.018). Unfavourable Baveno status was independently associated with acute decompensation. The probability of being free of HCC was significantly higher in low-risk patients (94.2 ± 1.8% vs. 87.6 ± 2.4%, p = 0.048). Liver-related mortality was not different between the 2 groups (p = 0.56). CONCLUSION: The Baveno VI criteria could predict clinical outcome in cACLD.

RESUMEN

BACKGROUND: Pathophysiology of acute encephalopathy in cirrhotic patients is not completely understood. Factors implicated include ammonia, inflammation, various metabolic disorders and drug toxicity. Recent studies have evidenced an increased permeability of the blood-brain barrier (BBB) in models of chronic liver disease and encephalopathy, either to solutes, or to leukocytes. A modification of the expression of BBB ATP-Binding Cassette (ABC) transporters, actively transporting endogenous and exogenous components through the BBB, has been described in models of acute liver failure. We hypothesized that a modification of ABC transporters expression may contribute to drug-induced acute encephalopathy in cirrhosis. MATERIEL AND METHODS: A rat model of cirrhosis induced by Bile Duct Ligation (BDL) was studied, and compared to a SHAM rat model. Rats were sacrificed and brains studied after decapitation. Genic expression of ABC transporters, including P-gp, BCRP, MRP1, MRP2, MRP4 and MRP5 was evaluated by RT-qPCR on isolated brain microvessels. Encephalopathy was assessed 6 weeks after surgery by a trail suspension test and an Open Field Test. RESULTS: BDL rats developed a histologically proven cirrhosis and displayed a higher ammonemia than SHAM rats (183 µmol/L vs 53 µmol/L, p = 0.0003). BDL rats presented with encephalopathy shown by neurobehavioral tests. MRP2 was not detected neither in BDL nor in SHAM rats. There was a decrease in the genic expression of MRP5 6 weeks after surgery. Expressions of P-gp, BCRP, MRP1 and MRP4 were not different between the 2 groups. CONCLUSION: We suggest that acute encephalopathy in cirrhotic BDL rats may be associated to a modification of ABC transporter MRP5 on the BBB, that could be responsible for a decrease clearance of neurotoxic agents.

RESUMEN

Portal hypertension (PHT) and hepatocellular carcinoma (HCC) are complications of cirrhosis which often coexist, rending the management more complex. HCC is generally considered as a contraindication for transjugular intrahepatic portosystemic shunt (TIPS). We studied the outcome of 8 patients treated by TIPS after HCC diagnosis between 2010 and 2020. TIPS wasn't associated with worsening of liver function or tumor spreading and all patients underwent liver transplantation. TIPS should be considered in case of HCC, especially for variceal bleeding or as a bridge to HCC treatments that are discarded due to PHT levels/ascites by improving liver function before liver transplantation.

RESUMEN

Compensated advanced chronic liver disease (cACLD) describes the spectrum of advanced fibrosis/cirrhosis in asymptomatic patients at risk of developing clinically significant portal hypertension (CSPH, defined by a hepatic venous pressure gradient (HVPG) ≥10 mmHg). Patients with cACLD are at high risk of liver-related morbidity and mortality. In patients at risk of chronic liver disease, cACLD is strongly suggested by a liver stiffness (LSM) value >15 kPa or clinical/biological/radiological signs of portal hypertension, and ruled out by LSM <10 kPa, or Fibrotest® ≤0.58, or Fibrometer® ≤0.786. Patients with chronic liver disease (excluding vascular diseases) with a LSM <10 kPa are at low risk of developing portal hypertension complications. The presence of CSPH can be strongly suspected when LSM is ≥20 kPa. In a patient without clinical, endoscopic or radiological features of portal hypertension, measurement of the HVPG is recommended before major liver or intra-abdominal surgery, before extra-hepatic transplantation and in patients with unexplained ascites. Endoscopic screening for oesophageal varices can be avoided in patients with LSM <20 kPa and a platelet count >150 G/L (favourable Baveno VI criteria) at the time of diagnosis. There is no non-invasive method alternative for oeso-gastroduodenal endoscopy in patients with unfavourable Baveno criteria (liver stiffness ≥20 kPa or platelet count ≤50 G/l). Platelet count and liver stiffness measurements must be performed once a year in patients with cACLD with favourable Baveno VI criteria at the time of diagnosis. A screening oeso-gastroduodenal endoscopy is recommended if Baveno VI criteria become unfavourable.

RESUMEN

BACKGROUND AND AIMS: Portal hypertension (PHT) and hepatocellular carcinoma (HCC) are major complication of cirrhosis which significantly contribute to morbidity and mortality. In this review, we aim to describe the consequences of both angiogenesis and inflammation in the pathogenesis of PHT and HCC, but also the difficulty to propose adapted treatment when PHT and HCC coexist in the same patients. METHODS: Studies for review in this article were retrieved from the PubMed database using literature published in English until March 2021. RESULTS: Portal hypertension occurs secondary to an increase of intrahepatic vascular resistances, the opening of portosystemic collateral vessels and the formation of neovessels, related to vascular endothelial growth factor (VEGF). Recently, bacterial translocation-mediated inflammation was also identified as a major contributor to PHT. Interestingly, VEGF and chronic inflammation also contribute to HCC occurrence. As PHT and HCC often coexist in the same patient, management of PHT and its related complications as well as HCC treatment appear more complex. Indeed, PHT-related complications such as significant ascites may hamper the access to HCC treatment and the presence of HCC is also independently associated with poor prognosis in patients with acute variceal bleeding related to PHT. Due to their respective mechanism of action, the combination of Atezolizumab and Bevacizumab for advanced HCC may impact the level of PHT and its related complications and to date, no real-life data are available. CONSLUSIONS: Appropriate evaluation and treatment of PHT remains a major issue in order to improve the outcome of HCC patients.

RESUMEN

Transjugular intrahepatic portosystemic shunt is a percutaneous radiologic-guided procedure that aims to reduce portal hypertension by creating a shunt between the portal venous system and the hepatic venous system. The most common cause of portal hypertension is liver cirrhosis in Western countries. Two main indications of transjugular intrahepatic portosystemic shunt are validated by randomised controlled studies in patients with cirrhosis and variceal bleeding (salvage transjugular intrahepatic portosystemic shunt, early transjugular intrahepatic portosystemic shunt or rebleeding despite an optimal secondary prophylaxis) or refractory ascites. Careful selection of the patients is crucial in order to prevent posttransjugular intrahepatic portosystemic shunt complications, including liver failure, posttransjugular intrahepatic portosystemic shunt encephalopathy occurrence and cardiac decompensation, for a better long-term outcome. In this review, we will discuss transjugular intrahepatic portosystemic shunt indications in 2020 in patients with cirrhosis and portal hypertension, with a special focus on variceal bleeding and refractory ascites. Then, we will describe transjugular intrahepatic portosystemic shunt-related complications, the contraindications and the current knowledge on patient's selection.

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

OBJECTIVE: No efficient medical treatment is available for severe acute hepatitis (SAH) except N-acetylcysteine for acetaminophen-induced acute liver failure. The human C-type lectin Reg3α, referred to as ALF-5755, improved survival in an animal model of acute liver failure and was well tolerated in a phase 1 trial in humans. We performed a phase 2a trial of ALF5755 in non-acetaminophen induced SAH. DESIGN: double-blind, randomized, placebo-controlled study. The primary end-point was the improvement in the coagulation protein synthesis assessed by the change of Prothrombin (PR) during the 72 hours following treatment initiation calculated as PRH0 minus PRH72 divided by 72 (PR slope H0H72). Intention to treat (ITT) and per-protocol (PP) analysis of the entire group and the Hepatitis B virus (HBV)/AIH (auto-immune hepatitis) sub-group were done separately. RESULTS: 57 patients were included. Twenty-eight received ALF-5755, 29 the placebo. Etiologies were: Hepatitis A (n = 10), HBV (n = 13), AIH (n = 9), drug-induced (n = 8), other (n = 17). On the whole group, nor the PR slope H0H72 (0.18±0.31 vs 0.25±0.32), nor the transplant-free survival rate at day 21 (75 vs 86%) differed between groups. Conversely, in the HBV-AIH subgroup, in which ALF was more severe, PR slope H0-H72 was higher in the ALF-5755 arm, the difference being significant in PP analysis (0.048±0.066 vs -0.040±0.099, p = 0.04); the median length of hospitalization was lower in the ALF-5755 group (8 vs 14 days, p = 0.02). CONCLUSION: ALF-5755 was not efficient in a ITT analysis performed on the whole sample; however it led to a significant, although moderate, clinical benefit in a PP analysis of the sub-group of patients with HBV or AIH related SAH. As HBV is the major cause of SAH in Asia and Africa and AIH a growing cause, this study emphasizes the need to pursuit the evaluation of this novel medical treatment of SAH.

RESUMEN

BACKGROUND/AIMS: According to guidelines, the histological diagnosis of severe alcoholic steatohepatitis (ASH) can require liver biopsy if a specific treatment is needed. The blood test AshTest (BioPredictive, Paris, France) has been initially validated for the non-invasive diagnosis of ASH in a large population of heavy drinkers. The aim was to validate the AshTest accuracy in the specific context of use of patients with suspected severe ASH, in order to reduce the need for transjugular biopsy before deciding treatment. METHODS: The reference was liver biopsy, performed using the transjugular route, classified according to its histological severity as none, minimal, moderate or severe. Biopsies were assessed by the same experienced pathologist, blinded to simultaneous AshTest results. RESULTS: A total of 123 patients with severe clinical ASH (recent jaundice and Maddrey function greater or equal to 32) were included, all had cirrhosis and 80% had EASL histological definition of ASH. 95% of patients received prednisolone; and the 2-year mortality was 63%. The high AshTest performance was confirmed both for the binary outcome [AUROC = 0.803 (95%CI 0.684-0.881)] significantly higher than the AST/ALT AUROC [0.603 (0.462-0.714); P<0.001], and for the severity of ASH-score system by the Obuchowski measures for [mean (SE) 0.902 (0.017) vs. AST/ALT 0.833 (0.023); P = 0.01], as well as for the diagnosis and severity of ballooning, PMN and Mallory bodies. According to attributability of discordances, AshTest had a 2-7% risk of 2 grades misclassification. CONCLUSION: These results confirmed the diagnostic performance of AshTest in cirrhotic patients with severe clinical ASH, in the specific context of use of corticosteroid treatment. AshTest is an appropriate non-invasive alternative to transjugular liver biopsy.

RESUMEN

BACKGROUND: One study has suggested that markers of acute hepatitis E virus (HEV) infection are present in 3.6% of patients with severe alcoholic hepatitis (AH). However, validation of these preliminary results is lacking, as well as the impact of HEV infection on the 6-month survival. AIMS: The aims of this study were to evaluate the prevalence of HEV infection markers in an external cohort of patients with histologically proven severe AH and to assess the impact of markers of acute HEV infection on the 6-month survival and the need for liver transplantation (LT). PATIENTS AND METHODS: Patients admitted for severe AH from January 2008 to June 2014 were analysed. HEV serology (IgM and IgG) was retrospectively performed. RESULTS: Ninety-three patients were analysed (male sex 77.4%, age 53±9 years, Maddrey discriminant function 65±32, MELD score 24±6). Six patients (6.5%) had markers of acute HEV infection (IgM+and IgG+), 11 (11.8%) of past HEV infection (IgG+and IgM-) and 76 (81.7%) had a negative serology (IgM- and IgG-). Initial presentation and biological characteristics were not different between IgM+ and IgM- patients, except for the aspartate aminotransferase level (P<0.001). Markers of acute HEV infection had no impact on response to corticosteroids, 1-, 3- or 6-month survival, and the need for LT. Three patients showed symptomatic acute HEV at onset of acute AH: two were treated with ribavirin during the acute phase: one patient died and one patient underwent LT. CONCLUSION: Markers of acute HEV infection were present in 6.5% of patients in our cohort of cirrhotics with histologically proven severe AH, without any impact on short-term or long-term outcome. Whether systematic screening of acute HEV infection in this population should be performed remains an unsolved question.

RESUMEN

BACKGROUND & AIMS: Many patients with alcohol-associated cirrhosis also have diabetes, obesity, or insulin resistance-mediated steatosis, but little is known about how these disorders affect the severity of liver disease. We analyzed the prevalence and prognostic implications of metabolic risk factors (MRFs) such as overweight, diabetes, dyslipidemia, and hypertension in patients with alcohol-associated cirrhosis awaiting liver transplants. METHODS: We performed a retrospective study of 110 patients with alcohol-associated cirrhosis (77% male; mean age, 55 y; 71% with >6 mo of abstinence) who received liver transplants at a single center in Paris, France, from 2000 through 2013. We collected data on previous exposure to MRFs, steatosis (>10% in the explant), and histologically confirmed hepatocellular carcinoma (HCC). RESULTS: HCC was detected in explants from 29 patients (26%). Steatosis was detected in explants from 47 patients (70% were abstinent for ≥6 mo); 50% had a history of overweight or type 2 diabetes. Fifty-two patients (47%) had a history of MRFs and therefore were at risk for nonalcoholic fatty liver disease. A higher proportion of patients with MRF had HCC than those without MRF (46% vs 9%; P < .001). A previous history of overweight or type 2 diabetes significantly increased the risk for HCC (odds ratio, 6.23; 95% confidence interval [CI], 2.47-15.76, and odds ratio, 4.63; 95% CI, 1.87-11.47, respectively; P < .001). MRF, but not steatosis, was associated with the development of HCC (odds ratio, 11.76; 95% CI, 2.60-53; P = .001) independent of age, sex, amount of alcohol intake, or severity of liver disease. CONCLUSIONS: Patients with alcohol-associated cirrhosis who received transplants frequently also had nonalcoholic fatty liver disease. MRFs, particularly overweight, obesity, and type 2 diabetes, significantly increase the risk of HCC.

RESUMEN

BACKGROUND & AIMS: All trials on severe alcoholic hepatitis (AH) have included patients with "pure" AH, i.e., without concomitant gastrointestinal bleeding (GIB). Severe AH is often suspected in cirrhotic patients with GIB. We aimed at (1) assessing the prevalence of AH in patients with GIB and Maddrey discriminant function (DF) ⩾32; (2) comparing the outcome in AH patients with or without GIB (AH-GIB+, AH-GIB-); and (3) assessing the performance of the Lille model for survival in AH-GIB+ patients. METHODS: We retrospectively included all patients with alcoholic cirrhosis admitted between January 2005 and March 2011 with the following: (1) jaundice <3 months; (2) DF ⩾32 at admission; (3) bilirubin level >50 µmol/L; and (4) active drinking. Exclusion criteria were advanced hepatocellular carcinoma, other etiology of cirrhosis, severe comorbidities and DF <32 after stabilization. In our centre, we systematically plan a liver biopsy for these patients. Patients with severe AH received prednisolone. RESULTS: We screened 161 patients (86 GIB+, 75 GIB-), and analyzed data for 58 and 47 patients in each group, respectively. The 2 groups did not differ in prevalence of AH (77.3% vs. 81%), demographic data, MELD/Child-Pugh score, or DF. The 2 groups were similar in 6-month probability of survival (73.9 ± 6.0% vs. 69.9 ± 7%, p=0.49). The probability of developing infection was lower for AH-GIB+ patients (24.1% vs. 44.7%, p=0.04). The AUC for the Lille model in predicting 6-month survival was 0.71 ± 0.06 for all patients and 0.74 ± 0.06 for AH-GIB+ patients (p>0.05). CONCLUSIONS: Prevalence of AH is 80% for patients with cirrhosis and GIB, recent jaundice and DF ⩾32. Infection was lower for AH-GIB+ patients, which suggests a beneficial role of antibiotic prophylaxis treatment. Survival among subjects with GIB was the same as among subjects without GIB.
