Endoscopic resection of early esophageal tumors in patients with cirrhosis or portal hypertension: a multicenter observational study.

BACKGROUND: Liver cirrhosis and esophageal cancer share several risk factors, such as alcohol intake and excess weight. Endoscopic resection is the gold standard treatment for superficial tumors. Portal hypertension and coagulopathy may increase the bleeding risk in these patients. This study aimed to assess the safety and efficacy of endoscopic resection for early esophageal neoplasia in patients with cirrhosis or portal hypertension. METHODS: This retrospective multicenter international study included consecutive patients with cirrhosis or portal hypertension who underwent endoscopic resection in the esophagus from January 2005 to March 2021. RESULTS: 134 lesions in 112 patients were treated, including by endoscopic submucosal dissection in 101 cases (75 %). Most lesions (128/134, 96 %) were in patients with liver cirrhosis, with esophageal varices in 71 procedures. To prevent bleeding, 7 patients received a transjugular intrahepatic portosystemic shunt, 8 underwent endoscopic band ligation (EBL) before resection, 15 received vasoactive drugs, 8 received platelet transfusion, and 9 underwent EBL during the resection procedure. Rates of complete macroscopic resection, en bloc resection, and curative resection were 92 %, 86 %, and 63 %, respectively. Adverse events included 3 perforations, 8 delayed bleedings, 8 sepsis, 6 cirrhosis decompensations within 30 days, and 22 esophageal strictures; none required surgery. In univariate analysis, cap-assisted endoscopic mucosal resection was associated with delayed bleeding (P = 0.01). CONCLUSIONS: In patients with liver cirrhosis or portal hypertension, endoscopic resection of early esophageal neoplasia appeared to be effective and should be considered in expert centers with choice of resection technique, following European Society of Gastrointestinal Endoscopy guidelines to avoid undertreatment.

The PRSS3P2 and TRY7 deletion copy number variant modifies risk for chronic pancreatitis.

BACKGROUND: PRSS1 and PRSS2 constitute the only functional copies of a tandemly-arranged five-trypsinogen-gene cluster (i.e., PRSS1, PRSS3P1, PRSS3P2, TRY7 and PRSS2) on chromosome 7q35. Variants in PRSS1 and PRSS2, including missense and copy number variants (CNVs), have been reported to predispose to or protect against chronic pancreatitis (CP). We wondered whether a common trypsinogen pseudogene deletion CNV (that removes two of the three trypsinogen pseudogenes, PRSS3P2 and TRY7) might be associated with CP causation/predisposition. METHODS: We analyzed the common PRSS3P2 and TRY7 deletion CNV in a total of 1536 CP patients and 3506 controls from France, Germany, India and Japan by means of quantitative fluorescent multiplex polymerase chain reaction. RESULTS: We demonstrated that the deletion CNV variant was associated with a protective effect against CP in the French, German and Japanese cohorts whilst a trend toward the same association was noted in the Indian cohort. Meta-analysis under a dominant model yielded a pooled odds ratio (OR) of 0.68 (95% confidence interval (CI) 0.52-0.89; p = 0.005) whereas an allele-based meta-analysis yielded a pooled OR of 0.84 (95% CI 0.77-0.92; p = 0.0001). This protective effect is explicable by reference to the recent finding that the still functional PRSS3P2/TRY7 pseudogene enhancers upregulate pancreatic PRSS2 expression. CONCLUSIONS: The common PRSS3P2 and TRY7 deletion CNV was associated with a reduced risk for CP. This finding provides additional support for the emerging view that dysregulated PRSS2 expression represents a discrete mechanism underlying CP predisposition or protection.

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.

Infected pancreatic necrosis complicating severe acute pancreatitis in critically ill patients: predicting catheter drainage failure and need for necrosectomy.

BACKGROUND: Recent guidelines advocate a step-up approach for managing suspected infected pancreatic necrosis (IPN) during acute pancreatitis. Nearly half the patients require secondary necrosectomy after catheter drainage. Our primary objective was to assess the external validity of a previously reported nomogram for catheter drainage, based on four predictors of failure. Our secondary objectives were to identify other potential predictors of catheter-drainage failure. We retrospectively studied consecutive patients admitted to the intensive care units (ICUs) of three university hospitals in France between 2012 and 2016, for severe acute pancreatitis with suspected IPN requiring catheter drainage. We assessed drainage success and failure rates in 72 patients, with success defined as survival without subsequent necrosectomy and failure as death and/or subsequent necrosectomy required by inadequate improvement. We plotted the receiver operating characteristics (ROC) curve for the nomogram and computed the area under the curve (AUROC). RESULTS: Catheter drainage alone was successful in 32 (44.4%) patients. The nomogram predicted catheter-drainage failure with an AUROC of 0.71. By multivariate analysis, catheter-drainage failure was independently associated with a higher body mass index [odds ratio (OR), 1.12; 95% confidence interval (95% CI), 1.00-1.24; P = 0.048], heterogeneous collection (OR, 16.7; 95% CI, 1.83-152.46; P = 0.01), and respiratory failure onset within 24 h before catheter drainage (OR, 18.34; 95% CI, 2.18-154.3; P = 0.007). CONCLUSION: Over half the patients required necrosectomy after failed catheter drainage. Newly identified predictors of catheter-drainage failure were heterogeneous collection and respiratory failure. Adding these predictors to the nomogram might help to identify patients at high risk of catheter-drainage failure. CLINICALTRIALS: gov number: NCT03234166.

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.

Common genetic variation in alcohol-related hepatocellular carcinoma: a case-control genome-wide association study.

BACKGROUND: Hepatocellular carcinoma is a frequent consequence of alcohol-related liver disease, with variable incidence among heavy drinkers. We did a genome-wide association study (GWAS) to identify common genetic variants for alcohol-related hepatocellular carcinoma. METHODS: We conducted a two-stage case-control GWAS in a discovery cohort of 2107 unrelated European patients with alcohol-related liver disease aged 20-92 years recruited between Oct 22, 1993, and March 12, 2017. Cases were patients with alcohol-related hepatocellular carcinoma diagnosed by imaging or histology. Controls were patients with alcohol-related liver disease without hepatocellular carcinoma. We used an additive logistic regression model adjusted for the first ten principal components to assess genetic variants associated with alcohol-related hepatocellular carcinoma. We did another analysis with adjustment for age, sex, and liver fibrosis. New candidate associations (p<1 × 10-6) and variants previously associated with alcohol-related hepatocellular carcinoma were evaluated in a validation cohort of 1933 patients with alcohol-related liver disease aged 29-92 years recruited between July 21, 1995, and May 2, 2019. We did a meta-analysis of the two case-control cohorts. FINDINGS: The discovery cohort included 775 cases and 1332 controls. Of 7 962 325 variants assessed, we identified WNT3A-WNT9A (rs708113; p=1·11 × 10-8) and found support for previously reported regions associated with alcohol-related hepatocellular carcinoma risk at TM6SF2 (rs58542926; p=6·02 × 10-10), PNPLA3 (rs738409; p=9·29 × 10-7), and HSD17B13 (rs72613567; p=2·49 × 10-4). The validation cohort included 874 cases and 1059 controls and three variants were replicated: WNT3A-WNT9A (rs708113; p=1·17 × 10-3), TM6SF2 (rs58542926; p=4·06 × 10-5), and PNPLA3 (rs738409; p=1·17 × 10-4). All three variants reached GWAS significance in the meta-analysis: WNT3A-WNT9A (odds ratio 0·73, 95% CI 0·66-0·81; p=3·93 × 10-10), TM6SF2 (1·77, 1·52-2·07; p=3·84×10-13), PNPLA3 (1·34, 1·22-1·47; p=7·30 × 10-10). Adjustment for clinical covariates yielded similar results. We observed an additive effect of at-risk alleles on alcohol-related hepatocellular carcinoma. WNT3A-WNT9A rs708113 was not associated with liver fibrosis. INTERPRETATION: WNT3A-WNT9A is a susceptibility locus for alcohol-related hepatocellular carcinoma, suggesting an early role of the Wnt-ß-catenin pathway in alcohol-related hepatocellular carcinoma carcinogenesis.

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.

Phase 2 trial comparing sorafenib, pravastatin, their combination or supportive care in HCC with Child-Pugh B cirrhosis.

BACKGROUND AND AIMS: There is limited data regarding the role for systemic treatment in patients with Hepatocellular Carcinoma with Child-Pugh B cirrhosis. METHODS: PRODIGE 21 was a multicentric prospective non-comparative randomized trial. Patients were randomized to receive sorafenib (Arm A), pravastatin (Arm B), sorafenib-pravastatin (Arm C) combination, or best supportive care (Arm D). Primary endpoint was time to progression (TTP), secondary endpoints included safety and overall survival (OS). RESULTS: 160 patients were randomized and 157 patients were included in the final analysis. 86% of patients were BCLC C and 55% had macrovascular invasion. The safety profiles of the drugs were as expected. Median TTP was 3.5, 2.8, 2.0 and 2.2 months in arms A, B, C and D, respectively, but analysis was limited by the number of patients deceased without radiological progression (59%). Median OS was similar between the four arms: 3.8 [95% CI: 2.4-6.5], 3.1 [95% CI: 1.9-4.3], 4.0 [95% CI: 3.2-5.5] and 3.5 months [95% CI: 2.2-5.4] in arms A, B, C and D, respectively. Median OS was 4.0 months [95% CI: 3.3-5.5] for patients treated with sorafenib, vs 2.9 months [95% CI: 2.2-3.9] for patients not treated with sorafenib. In patients with ALBI grade 1/2, median OS was 6.1 months [95% CI: 3.8-8.3] in patients treated with sorafenib vs 3.1 months [95% CI: 1.9-4.8] for patients not treated with sorafenib. CONCLUSION: In the overall Child-Pugh B population, neither sorafenib nor pravastatin seemed to provide benefit. In the ALBI grade 1/2 sub-population, our trial suggests potential benefit of sorafenib. CLINICAL TRIAL REGISTRATION: The study was referenced in clinicaltrials.gov (NCT01357486).

Selective SIRPα blockade reverses tumor T cell exclusion and overcomes cancer immunotherapy resistance.

T cell exclusion causes resistance to cancer immunotherapies via immune checkpoint blockade (ICB). Myeloid cells contribute to resistance by expressing signal regulatory protein-α (SIRPα), an inhibitory membrane receptor that interacts with ubiquitous receptor CD47 to control macrophage phagocytosis in the tumor microenvironment. Although CD47/SIRPα-targeting drugs have been assessed in preclinical models, the therapeutic benefit of selectively blocking SIRPα, and not SIRPγ/CD47, in humans remains unknown. We report a potent synergy between selective SIRPα blockade and ICB in increasing memory T cell responses and reverting exclusion in syngeneic and orthotopic tumor models. Selective SIRPα blockade stimulated tumor nest T cell recruitment by restoring murine and human macrophage chemokine secretion and increased anti-tumor T cell responses by promoting tumor-antigen crosspresentation by dendritic cells. However, nonselective SIRPα/SIRPγ blockade targeting CD47 impaired human T cell activation, proliferation, and endothelial transmigration. Selective SIRPα inhibition opens an attractive avenue to overcoming ICB resistance in patients with elevated myeloid cell infiltration in solid tumors.

Impact of prior antibiotics on infected pancreatic necrosis microbiology in ICU patients: a retrospective cohort study.

BACKGROUND: Recent guidelines advise against prophylactic antibiotics in patients with necrotizing pancreatitis, advocating instead a step-up drainage and necrosectomy strategy with antibiotics as dictated by microbiological findings. However, prompt antibiotic therapy is recommended in patients with sepsis or septic shock, a possible presentation of infected pancreatic necrosis (IPN). Consequently, in many critically ill patients with IPN, pancreatic samples are collected only after broad-spectrum antibiotic therapy initiation. Whether this prior antibiotic exposure alters the microbiological findings is unknown. The main objective was to determine whether prior antibiotic exposure sterilized the samples collected during procedures for suspected IPN in patients admitted to the intensive care unit (ICU) for acute pancreatitis with suspected IPN. We retrospectively studied 56 consecutive ICU patients admitted with suspected IPN. We collected details on the microbiological samples and antimicrobials used. A definite diagnosis of IPN was given when bacteria were identified in pancreatic samples. RESULTS: In all, 137 pancreatic samples were collected, including 91 (66.4%) after antibiotic therapy initiation. IPN was confirmed in 48 (86%) patients. The proportion of positive samples was 74 (81.3%) in antibiotic-exposed patients and 32/46 (69.5%) in unexposed patients (p = 0.58). Of the 74 positive samples from exposed patients, 62 (84%) had organisms susceptible to the antibiotics used. One-third of samples contained more than one organism. Among patients with IPN, 37.5% had positive blood cultures. Multidrug- or extensively drug-resistant bacteria were identified at some point in half the patients. Enterobacter cloacae complex was more frequent in the exposed group (p = 0.02), as were Gram-negative anaerobic bacteria (p = 0.03). CONCLUSION: Antibiotic exposure before sampling did not seem to affect culture positivity of pancreatic samples to confirm IPN, but may affect microbiological findings. Our results suggest that, in patients with sepsis and suspected IPN, antibiotics should be started immediately and pancreatic samples obtained as soon as possible thereafter. In other situations, antibiotics can be withheld until the microbiological results of pancreatic samples are available, to ensure accurate targeting of the spectrum to bacterial susceptibility patterns.

Nivolumab-induced celiac-like enteropathy in patient with metastatic renal cell carcinoma: Case report and review of the literature.

Nivolumab may induce severe celiac-like enteropathy, that may appear very rapidly, after only two injections of nivolumab, and may be successfully treated with corticosteroids. This observation underlines the importance of histological analysis of duodenal biopsies and the necessity to rule out a real celiac disease in patients with nivolumab-induced diarrhea.

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.

Immune Alterations in Patients With Type 1 Autoimmune Hepatitis Persist Upon Standard Immunosuppressive Treatment.

Autoimmune hepatitis (AIH) is a rare disease characterized by an immune attack of the liver. This study consists of a comprehensive analysis of immune alterations related to AIH at diagnosis, and during remission phase under treatment. A total of 37 major lymphocyte populations were analyzed from the peripheral blood of new-onset AIH patients (AIHn; n = 14), AIH patients with controlled disease (n = 11), and healthy subjects (n = 14). Liver biopsy analyses were performed to complete the blood phenotypic analysis. Four blood lymphocyte populations were significantly altered in AIHn patients at diagnosis compared with healthy subjects. Levels of mucosal-associated invariant T cells (MAIT), Type 1/Type 17 helper (Th1/ Th17) cells, clusters of differentiation (CD4) T cells, and invariant natural killer T cells were decreased, whereas MAIT granzyme B+ (GrB) cells were increased. A trend toward an increase of CD8+CD161+GrB+ cells was also observed. These alterations were not restored with standard immunosuppressive treatments. In the liver of AIHn patients, CD4, forkhead box P3 (Foxp3), and MAIT cell markers were enriched in the portal tract, and CD8, CD161, and GrB markers were enriched in the hepatic lobule. During remission, the hepatic lobule was clear of infiltrating T cells, but residual CD4 and MAIT cells were found in the portal tract, where Foxp3 was decreased, as previously described. In vitro, MAIT cells were functionally altered in AIH patients. Ex vivo MAIT cell activity (GrB) was linked to severe fibrosis. Conclusion: Our work proposes a global view of the lymphocyte alterations from diagnosis to remission phase in AIH patients. The absence of blood immune homeostasis restoration and the persistence of a CD4 infiltrate in the liver under standard immunosuppression could form the basis of the high risk of relapse observed in AIH.

Risk factors and outcomes of infected pancreatic necrosis: Retrospective cohort of 148 patients admitted to the ICU for acute pancreatitis.

OBJECTIVE: The primary objective of this article is to identify risk factors for infected pancreatic necrosis (IPN) in patients admitted to the intensive care unit (ICU) for severe acute pancreatitis. We also described outcomes of IPN. BACKGROUND: Acute pancreatitis is common and associated with multiple, potentially life-threatening complications. Over the last decade, minimally invasive procedures have been developed to treat IPN. METHODS: We retrospectively studied consecutive patients admitted for severe acute pancreatitis to the ICUs of the Nantes University Hospital in France, between 2012 and 2015. Logistic regression was used to evaluate potential associations linking IPN to baseline patient characteristics and outcomes. RESULTS: Of the 148 included patients, 26 (17.6%) died. IPN developed in 62 (43%) patients and consistently required radiological, endoscopic, and/or surgical intervention. By multivariate analysis, factors associated with IPN were number of organ failure (OF) (for ≥ 3: OR, 28.67 (6.23-131.96), p < 0.001) and portosplenomesenteric venous thrombosis (OR, 8.16 (3.06-21.76)). CONCLUSION: IPN occurred in nearly half our ICU patients with acute pancreatitis and consistently required interventional therapy. Number of OFs and portosplenomesenteric venous thrombosis were significantly associated with IPN. Early management of OF may reduce IPN incidence, and management of portosplenomesenteric venous thrombosis should be investigated.

The epidemiology of Budd-Chiari syndrome in France.

INTRODUCTION: Epidemiological data is lacking on primary Budd-Chiari syndrome (BCS) in France. METHODS: Two approaches were used: (1) A nationwide survey in specialized liver units for French adults. (2) A query of the French database of discharge diagnoses screening to identify incident cases in adults. BCS associated with cancer, alcoholic/viral cirrhosis, or occurring after liver transplantation were classified as secondary. RESULTS: Approach (1) 178 primary BCS were identified (prevalence 4.04 per million inhabitants (pmi)), of which 30 were incident (incidence 0.68 pmi). Mean age was 40 ±â€¯14 yrs. Risk factors included myeloproliferative neoplasms (MPN) (48%), oral contraceptives (35%) and factor V Leiden (16%). None were identified in 21% of patients, ≥2 risk factors in 25%. BMI was higher in the group without any risk factor (25.7 kg/m2 vs 23.7 kg/m2, p < 0.001). Approach (2) 110 incident primary BCS were admitted to French hospitals (incidence 2.17 pmi). MPN was less common (30%) and inflammatory local factors predominated (39%). CONCLUSION: The entity of primary BCS as recorded in French liver units is 3 times less common than the entity recorded as nonmalignant hepatic vein obstruction in the hospital discharge database. The former entity is mostly related to MPN whereas the latter with abdominal inflammatory diseases.

Cirrhotic patients with portal hypertension-related bleeding and an indication for early-TIPS: a large multicentre audit with real-life results.

BACKGROUND: The Baveno VI consensus meeting concluded that an early TIPS must be considered in high-risk cirrhotic patients presenting with variceal bleeding (VB) (Child B + active bleeding at endoscopy or Child C10-13 patients). Whether this therapeutic approach is feasible in a real-life setting remains unclear. AIMS: To determine (1) the proportion of patients eligible for early-TIPS among cirrhotic patients with VB, (2) the proportion of these patients who underwent early-TIPS placement and the main reasons for discarding TIPS, and (3) the outcomes of patients who experienced early-TIPS placement in a large, national, prospective, multicentre audit including academic and non-academic centres. MATERIALS AND METHODS: All French centres recruiting gastrointestinal bleeding were invited to participate. All consecutive patients with cirrhosis and PHT-related bleeding were included. RESULTS: 964 patients were included (58 centres: 26 academic, 32 non-academic; patient characteristics: male sex, 77%; age, 59.6 ± 12.1 years; aetiologies of cirrhosis (alcoholic,viral/other, 67%/15%/18%); source of bleeding (EV/GV/other, 80/11/9%); active bleeding at endoscopy 34%; Child A 21%/B 44%/C 35%. Overall, 35% of the patients were eligible for early-TIPS, but only 6.8%, displaying less severe cirrhosis underwent early-TIPS placement. The main reason for discarding TIPS was a lack of availability. The actuarial probability of survival at one year was significantly increased in early-TIPS patients (85.7±0.07% vs 58.9±0.03%, p=0.04). The severity of liver disease was the only parameter independently associated with improved one-year survival. CONCLUSION: In this real-life study, one-third of the cirrhotic patients admitted for VB fulfilled the criteria for early-TIPS placement, whereas only 7% had access to TIPS. TIPS was restricted to patients displaying less severe cirrhosis. The severity of liver disease was the only parameter that influenced survival.
