Abstract
BACKGROUND Acute kidney injury (AKI) is common in patients with cirrhosis. In 2015, the International Club of Ascites (ICA) proposed new definitions of AKI in order to improve the prediction of outcomes. Our aim was to assess the prevalence and prognostic value of ICA 2015 - AKI criteria in hospitalised patients with cirrhosis. METHODS We prospectively collected data from 405 consecutive cirrhotic patients admitted to the hospital between November 2016 and November 2017. AKI was diagnosed at inclusion according to ICA 2015 criteria, and was assessed to predict 30-day and 90-day in-hospital mortality. RESULTS AKI was diagnosed in 78 (19.3%) patients. AKI was independently associated with 90-day death (HR 7.61; 95% CI 4.75-12.19; p < 0.001). In hospital, 30-day and 90-day survival was lower in the group of patients with AKI compared to the group with no AKI (72% vs. 98%, p < 0.001; 64% vs. 96%, p < 0.001; and 49% vs. 81%, p < 0.001, respectively). Patients with stage 1a AKI had a lower 30-day and 90-day survival compared to the group of patients who did not develop AKI (71% vs. 96%, p < 0.001, and 71% vs. 91%, p < 0.01, respectively) and better survival than patients with more severe AKI (71% vs. 40%, p < 0.01). CONCLUSIONS AKI was independently associated with mortality in patients with cirrhosis, even at the very early 1a stage. Response to treatment improved survival, and was inversely proportional to the stage of AKI, which suggests that treatment should be started at the earliest stage of AKI.

Abstract
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.

Abstract
Considering the poor prognosis, severe and refractory ascites is a milestone in cirrhotic patients. Liver transplantation must be considered first. In the case of contraindication to liver transplantation or when the waiting period is estimated to be more than 6 months, transjugular intrahepatic portosystemic shunt should be discussed in eligible patients. Regardless of the type of treatment, a careful selection of patients is crucial to avoid further decompensation and specific complications of each treatment.

Abstract
BACKGROUND & AIMS Compared with drugs plus endoscopy, placement of transjugular portosystemic shunt within 72 hours of admission to the hospital (early or preventive transjugular intrahepatic portosystemic shunt [TIPS], also called preemptive TIPS) increases the proportion of high-risk patients with cirrhosis and acute variceal bleeding who survive for 1 year. However, the benefit of preemptive TIPS is less clear for patients with a Child-Pugh score of B and active bleeding (CP-B+AB). We performed an individual data meta-analysis to assess the efficacy of preemptive TIPS in these patients and identify factors associated with reduced survival of patients receiving preemptive TIPS. METHODS We searched publication databases for randomized controlled trials and observational studies comparing the effects of preemptive TIPS versus endoscopy plus nonselective beta-blockers in the specific population of high-risk patients with cirrhosis and acute variceal bleeding (CP-B+AB or Child-Pugh C, below 14 points), through December 31, 2019. We performed a meta-analysis of data from 7 studies (3 randomized controlled trials and 4 observational studies), comprising 1327 patients (310 received preemptive TIPS and 1017 received drugs plus endoscopy). We built adjusted models to evaluate risk using propensity score for baseline covariates. Multivariate Cox regression models were used to assess the factors associated with survival time. The primary endpoint was effects of preemptive TIPS versus drugs plus endoscopy on 1-year survival in the overall population as well as CP-B+AB and Child-Pugh C patients. RESULTS Overall, preemptive TIPS significantly increased the proportion of high-risk patients with cirrhosis and acute variceal bleeding who survived for 1 year, compared with drugs plus endoscopy (hazard ratio [HR] 0.443; 95% CI 0.323-0.607; P < .001). This effect was observed in CP-B+AB patients (HR 0.524; 95% CI 0.307-0.896; P = .018) and in patients with Child-Pugh C scores below 14 points (HR 0.374; 95% CI 0.253-0.553; P < .001). Preemptive TIPS significantly improved control of bleeding and ascites without increasing risk of hepatic encephalopathy in Child-Pugh C and CP-B+AB patients, compared with drugs plus endoscopy. Cox analysis of patients who received preemptive TIPS showed that patients could be classified into 3 categories for risk of death, based on age, serum level of creatinine, and Child-Pugh score. In each of these risk categories, preemptive TIPS increased the proportion of patients who survived for 1 year, compared with drugs plus endoscopy. CONCLUSIONS In a meta-analysis of data from 1327 patients with cirrhosis, acute variceal bleeding, and Child-Pugh score between 10 and 13 points or CP-B+AB, preemptive TIPS increased the proportion who survived for 1 year, in both subgroups separately, compared with drugs plus endoscopy.

Abstract
BACKGROUND AND AIMS Transjugular intrahepatic portosystemic shunt (TIPS) is now a standard for the treatment of portal hypertension-related complications. After the TIPS procedure, incidence and risk factors of cardiac decompensation are poorly known. The main objectives were to measure the incidence of the onset of cardiac decompensation after TIPS and identify the predictive factors. APPROACH AND RESULTS All patients with cirrhosis treated with TIPS between May 2011 and June 2016 were considered for inclusion. They received a cardiac assessment by standard biological parameters, transthoracic echocardiography, and right heart catheterization. Patients were followed for 1 year after TIPS insertion. The main endpoint was the incidence of cardiac decompensation requiring hospitalization. One hundred seventy-four patients were treated by TIPS during the period. One hundred patients who underwent a complete cardiac evaluation were included. A cardiac decompensation occurred in 20% of the patients. The parameters associated with the occurrence of severe cardiac decompensation were a prolonged QT interval corrected (462 vs. 443 ms; P = 0.05), an elevated pre-TIPS brain natriuretic peptide (BNP) or N-terminal pro-brain natriuretic peptide (NT-proBNP) level, an elevated E/A ratio (1.5 vs. 1.0; P = 0.001) and E/e' ratio (11 vs. 7; P < 0.001), and a left atrial dilatation (40 vs. 29 mL/m2 ; P = 0.011). The presence of aortic stenosis was also associated with cardiac decompensation. A level of BNP <40 pg/mL and NT-proBNP <125 pg/mL allowed identifying patients without risk of cardiac decompensation. Additionally, absence of diastolic dysfunction criteria at echocardiography ruled out the risk of further cardiac decompensation. CONCLUSIONS Hospitalization for cardiac decompensation is observed in 20% of patients in the year after TIPS insertion. Combining BNP or NT-proBNP levels and echocardiographic parameters should help improve patient selection.

Abstract
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.

Abstract
BACKGROUND & AIMS Hepatitis E virus (HEV) genotypes 3 and 4 cause sporadic cases of infection in developed countries. Being elderly and having an underlying liver disease are the main risk factors for death in this population. Chronic infection has been described in immunocompromised patients. Ribavirin is now the antiviral treatment of choice in solid-organ-transplant recipients with chronic HEV infection. We hypothesized that early short-term treatment of acute HEV infection may be useful for patients with risk factors or undergoing chemotherapy. METHODS Between July 2010 and January 2014, 21 patients diagnosed with acute HEV infection were treated with ribavirin, at 600-800 mg/day for up to 3 months. All serum samples were positive for HEV RNA. RESULTS Nine patients were treated for severe hepatitis. Six patients were aged >70 years. Four patients were receiving an immunosuppressive therapy for an autoimmune disease and two patients were undergoing chemotherapy for a malignancy. Two patients received a fixed-dose regimen. For all other patients, ribavirin was stopped when HEV became undetectable in the serum. The median duration of ribavirin treatment was 26 days. Two patients developed severe anaemia. Two patients with encephalopathy died. One patient relapsed transiently. All patients were cleared of HEV and regained normalized liver-enzyme levels. Immunosuppressive treatment and chemotherapy could be resumed. CONCLUSIONS Treatment of acute HEV infection using ribavirin seems safe and effective. Short-term treatment tailored to viraemia may be the best regimen for this indication.

Abstract
BACKGROUND & AIMS 30-40% of portal vein thrombosis (PVT) remains of unknown origin. An association between metabolic syndrome (MetS) and peripheral vein thrombosis has been reported but not with PVT, to date. The aim of this study was to investigate the association between MetS and PVT. METHODS Between 2003 and 2014, all consecutive patients with non-cirrhotic PVT were prospectively included. Patient's characteristics and risks factors were recorded at the time of inclusion. Controls were selected by random in the general population and were matched 1/1 according to age and sex. RESULTS Seventy-nine patients with PVT were included: 40 present with at least one risk factor for PVT (SPVT) and 39 were found to be idiopathic (IPVT). The prevalence of MetS was 25.6% in SPVT group vs. 47.4% in IPVT group and 17.9% in controls from the general population (C-IPVT: p=0.01). The waist circumference and body mass index were higher in the IPVT group than in the SPVT group (105 vs. 93cm, p=0.004 and 29.4 vs. 25.0kg/m(2), p=0.004) and in the C-IPVT group (105 vs. 92cm, p=0.001 and 29.4 vs. 25.8kg/m(2), p=0.003). Overweight was observed in 82.0% of patients in the IPVT group vs. 44% in the SPVT group (p=0.002) and 51% in the C-IPVT group (p=0.01). The mean visceral fat area was higher in IPVT than in SPVT (18,223mm(2)vs. 12,690mm(2), p=0.02). In multivariate analyses, an increase in waist circumference was the strongest parameter associated with idiopathic PVT. CONCLUSION Central obesity is associated with PVT and could become one of the main risk factors for digestive thromboses.

Abstract
BACKGROUND AND STUDY AIM Esophageal video capsule endoscopy (ECE) is a new technique that allows examination of the esophagus using a noninvasive approach. The aim of this study was to compare ECE with esophagogastroduodenoscopy (EGD) for the diagnosis of esophageal varices in patients with cirrhosis. PATIENTS AND METHODS A total of 330 patients with cirrhosis and with no known esophageal varices were prospectively enrolled. Patients underwent ECE first, followed by EGD (gold standard). The endoscopists who performed EGD were blind to the ECE result. Patient satisfaction was assessed using a visual analog scale (maximum score 100). RESULTS A total of 30 patients were excluded from the analysis because they did not undergo any endoscopic examinations. Patients (mean age 56 years; 216 male) had mainly alcoholic (45 %) or viral (27 %) cirrhosis. The diagnostic indices of ECE to diagnose and correctly stage esophageal varices were: sensitivity 76 % and 64 %, specificity 91 % and 93 %, positive predictive value 88 % and 88 %, and negative predictive value 81 % and 78 %, respectively. ECE patient satisfaction scored significantly higher than EGD (87 ± 22 vs. 58 ± 35; P < 0.0001). CONCLUSIONS ECE was well tolerated and safe in patients with liver cirrhosis and suspicion of portal hypertension. The sensitivity of ECE is not currently sufficient to replace EGD as a first exploration in these patients. However, due to its excellent specificity and positive predictive value, ECE may have a role in cases of refusal or contraindication to EGD. ECE might also improve compliance to endoscopic follow-up and aid important therapeutic decision making in the prophylaxis of bleeding.

Abstract
BACKGROUND The diagnostic performance of biochemical scores and artificial neural network models for portal hypertension and cirrhosis is not well established. AIMS To assess diagnostic accuracy of six serum scores, artificial neural networks and liver stiffness measured by transient elastography, for diagnosing cirrhosis, clinically significant portal hypertension and oesophageal varices. METHODS 202 consecutive compensated patients requiring liver biopsy and hepatic venous pressure gradient measurement were included. Several serum tests (alone and combined into scores) and liver stiffness were measured. Artificial neural networks containing or not liver stiffness as input variable were also created. RESULTS The best non-invasive method for diagnosing cirrhosis, portal hypertension and oesophageal varices was liver stiffness (C-statistics=0.93, 0.94, and 0.90, respectively). Among serum tests/scores the best for diagnosing cirrhosis and portal hypertension and oesophageal varices were, respectively, Fibrosis-4, and Lok score. Artificial neural networks including liver stiffness had high diagnostic performance for cirrhosis, portal hypertension and oesophageal varices (accuracy>80%), but were not statistically superior to liver stiffness alone. CONCLUSIONS Liver stiffness was the best non-invasive method to assess the presence of cirrhosis, portal hypertension and oesophageal varices. The use of artificial neural networks integrating different non-invasive tests did not increase the diagnostic accuracy of liver stiffness alone.

Abstract
UNLABELLED Transjugular intrahepatic portosystemic shunts (TIPS) is a second-line treatment because of an increased incidence of overt hepatic encephalopathy (OHE). A better selection of patients to decrease this risk is needed and one promising approach could be the detection of minimal hepatic encephalopathy (MHE). The aim of the present prospective study was to determine whether pre-TIPS minimal hepatic encephalopathy was predictive of post-TIPS OHE and to compare Psychometric Hepatic Encephalopathy Sum Score(PHES) and the Critical Flicker Frequency (CFF) in this setting. From May 2008 to January 2011, 54 consecutive patients treated with TIPS were included. PHES and CFF were performed 1 to 7 days before and after TIPS at months 1, 3, 6, 9, and 12 or until liver transplantation or death. Before TIPS, MHE was detected by PHES and CFF in 33% and 39% of patients, respectively. After the TIPS procedure, 19 patients (35%) experienced a total of 64 episodes of OHE. OHE developed significantly more often inpatients for whom an indication for TIPS had been refractory ascites, with a history of OHE or of renal failure, lower hemoglobin level, or MHE as diagnosed by CFF. Post-TIPS OHE was more accurately predicted by CFF than by PHES. Absence of MHE at CFF had a good negative predictive value (91%) for the risk of post-TIPS recurrent OHE, defined as the occurrence of three or more episodes of OHE or of one episode which lasted more than 15 days. The absence of pre-TIPS history of OHE and a CFF value equal to or greater than 39 Hz had a 100% negative predictive value for post-TIPS recurrent OHE. CONCLUSION Aiming to decrease the rate of post-TIPS HE, the use of CFF could help selecting patients for TIPS.

Abstract
BACKGROUND & AIMS In a recent randomized international clinical trial (RCT) in high-risk cirrhotic patients with acute variceal bleeding, the early use of transjugular intrahepatic portosystemic shunt (TIPS) was associated with marked and significant reductions in both treatment failure and mortality. The aim of this study was to confirm these results in clinical practice in the same centers of the RCT study. METHODS We retrospectively reviewed patients admitted for acute variceal bleeding and high risk of treatment failure (Child C <14 or Child B plus active bleeding), treated with early-TIPS (n=45) or drugs+endoscopic therapy (ET) (n=30). RESULTS Patients treated with early-TIPS had a much lower incidence of failure to control bleeding or rebleeding than patients receiving drug+ET (3 vs. 15; p <0.001). The 1-year actuarial probability of remaining free of this composite end point was 93% vs. 53% (p <0.001). The same was observed in mortality (1-year actuarial survival was 86% vs. 70% respectively; p=0.056). Actuarial curves of failure to control bleeding+rebleeding and of survival were well within the confidence intervals of those observed in the RCT. CONCLUSIONS This study supports the early use of TIPS in patients with cirrhosis and a high-risk variceal bleeding.

Abstract
BACKGROUND & AIMS Refractory ascites in patients with cirrhosis is associated with poor survival. TIPS is more effective than paracentesis for the prevention of recurrence of ascites but increases the risk of encephalopathy while survival remains unchanged. A more accurate selection of the patients might improve these results. The aim of the present study was to identify parameters of prognostic value for survival in patients with refractory ascites treated with TIPS. METHODS One hundred and five consecutive French patients with cirrhosis and refractory ascites treated with TIPS were used to assess parameters associated with 1-year survival. The model was then tested in two different cohorts: a local and prospective one including 40 patients from Toulouse, France, and an external one including 48 patients from Barcelona, Spain. RESULTS The actuarial rate of survival in the first 105 patients was 60% at 1 year. Using multivariate analysis, only lower bilirubin levels and higher platelet counts were independently associated with survival. The actuarial 1-year survival rate in patients with both a platelet count above 75×10(9)/L and a bilirubin level lower than 50 μmol/L [3mg/dl] was 73.1% as compared to 31.2%, in patients with a platelet count below 75×10(9)/L or a bilirubin level higher than 50 μmol/L. These results were confirmed in the two different validation cohorts. CONCLUSIONS The combination of a bilirubin level below 50 μmol/L and a platelet count above 75×10(9)/L is predictive of survival in patients with refractory ascites treated with TIPS. This simple score could be used at bedside to help choose the best therapeutic options.

Abstract
BACKGROUND Patients with cirrhosis in Child-Pugh class C or those in class B who have persistent bleeding at endoscopy are at high risk for treatment failure and a poor prognosis, even if they have undergone rescue treatment with a transjugular intrahepatic portosystemic shunt (TIPS). This study evaluated the earlier use of TIPS in such patients. METHODS We randomly assigned, within 24 hours after admission, a total of 63 patients with cirrhosis and acute variceal bleeding who had been treated with vasoactive drugs plus endoscopic therapy to treatment with a polytetrafluoroethylene-covered stent within 72 hours after randomization (early-TIPS group, 32 patients) or continuation of vasoactive-drug therapy, followed after 3 to 5 days by treatment with propranolol or nadolol and long-term endoscopic band ligation (EBL), with insertion of a TIPS if needed as rescue therapy (pharmacotherapy-EBL group, 31 patients). RESULTS During a median follow-up of 16 months, rebleeding or failure to control bleeding occurred in 14 patients in the pharmacotherapy-EBL group as compared with 1 patient in the early-TIPS group (P=0.001). The 1-year actuarial probability of remaining free of this composite end point was 50% in the pharmacotherapy-EBL group versus 97% in the early-TIPS group (P<0.001). Sixteen patients died (12 in the pharmacotherapy-EBL group and 4 in the early-TIPS group, P=0.01). The 1-year actuarial survival was 61% in the pharmacotherapy-EBL group versus 86% in the early-TIPS group (P<0.001). Seven patients in the pharmacotherapy-EBL group received TIPS as rescue therapy, but four died. The number of days in the intensive care unit and the percentage of time in the hospital during follow-up were significantly higher in the pharmacotherapy-EBL group than in the early-TIPS group. No significant differences were observed between the two treatment groups with respect to serious adverse events. CONCLUSIONS In these patients with cirrhosis who were hospitalized for acute variceal bleeding and at high risk for treatment failure, the early use of TIPS was associated with significant reductions in treatment failure and in mortality.

Abstract
BACKGROUND Hepatic venous pressure gradient (HVPG) is a prognostic marker in patients with cirrhosis. Transient elastography measures liver stiffness (LS). AIM To assess the correlation between LS and HVPG and to investigate the performance of transient elastography for the diagnosis of significant portal hypertension (PHT). METHODS Liver stiffness was measured by Fibroscan in 150 consecutive patients who underwent a liver biopsy with haemodynamic measurements. Usual clinical and biological data were collected. Significant PHT was defined as a HVPG > or = 10 mmHg. RESULTS Hepatic venous pressure gradient was found to be > or = 10 mmHg in 76 patients. Cirrhosis was diagnosed in 89 patients. HVPG was found to be correlated with: LS (rho = 0.858; P < 0.001) and inversely correlated with prothrombin index (rho = -0.718; P < 0.001). Regarding significant PHT, AUROC for LS and prothrombin index were 0.945 [0.904-0.987] and 0.892 [0.837-0.947] respectively. The cut-off value of 21 kPa accurately predicted significant PHT in 92% of the 144 patients for whom LS was successful. CONCLUSION Liver stiffness measurement is correlated with HVPG and transient elastography identifies patients with significant PHT.

Abstract
Up to 70% of the patients treated to prevent rebleeding will experience a bleeding episode within 2 years. The response should be adapted to the delay after the index bleed, the source and the severity of the haemorrhage, the underlying liver disease and the initial treatment to prevent rebleeding. Bleeding can be caused by endoscopic techniques themselves, which should incitate to complete obliteration rather than to switch to another therapy. Failure of drug therapy can be secondary to ineffectiveness, to a lack of compliance, or to an insufficient dosage. The two latter conditions may be corrected. Whenever a patient rebleeds in spite of optimal treatment, liver transplantation should be considered. When such a procedure is contra-indicated and in patients on the waiting list, a Transjugular intra-hepatic porto-systemic shunt (TIPS) should be performed.

Abstract
BACKGROUND AND AIMS Macronodules (MN) occurring in cirrhosis are considered to be precursor lesions for hepatocellular carcinoma (HCC). However, early molecular events in hepatocellular carcinogenesis are poorly understood. The aim of this study was to compare gene expression profiling between cirrhotic tissues, MN, and HCC, to identify genes early involved in liver carcinogenesis. METHODS Tissues were obtained from explanted livers: nine cirrhosis, 10 MN, and seven HCC. Total RNAs were extracted by RNeasy and reverse transcribed with labelled [(33)P]-alpha ATP. Hybridations were performed on Atlas Human Cancer 1.2 membranes (1176 genes). RESULTS A two-way hierarchical clustering algorithm successfully isolated specific gene expression profiles when comparing MN, cirrhosis, and HCC. A total of 16 and 14 genes were up- and down-expressed, respectively, in HCC as compared to cirrhotic tissues. The molecular signature of MN was characterized by the down-expression of 23 and 42 genes as compared to cirrhosis and HCC, respectively. Among them, Klf6 was down-expressed in all MN samples whereas it was over-expressed in cirrhosis and HCC. This result was confirmed at RNA level by quantitative real time-polymerase chain reaction and at protein level by Western blotting. However, no mutation in the exon 2 of Klf6 was detected. CONCLUSION We identified a molecular signature of MN characterized by a down-expression of several genes. One of them, Klf6 was found to be down-expressed in all MN without evidence of somatic mutations in the exon 2. This gene could be involved at an early stage of hepatocarcinogenesis.

Abstract
An 80% dysfunction rate at 2 years limits the use of transjugular intrahepatic portosystemic shunts (TIPS) in the treatment of complications of portal hypertension. The use of covered stents could improve shunt patency; however, long-term effect and safety remain unknown. Eighty patients randomized to be treated by TIPS either with a covered stent (Group 1) or an uncovered prosthesis (Group 2) were followed-up for 2 years. Doppler US was performed every 3 months. Angiography and portosystemic pressure gradient measurement were performed every 6 months or whenever dysfunction was suspected. Actuarial rates of primary patency in Groups 1 and 2 were 76% and 36% respectively (P=0.001). Clinical relapse occurred in four patients (10%) in Group 1 and 12 (29%) in Group 2 (P<0.05). Actuarial rates of being free of encephalopathy were 67% in Group 1 and 51% in Group 2 (P<0.05). Probability of survival was 58% and 45% at 2 years, respectively, in Groups 1 and 2 (NS). The mean Child-Pugh score improved only in Group 1 (from 8.1+/-1.6 to 7+/-2.2 at 2 years -P<0.05). We also compared the Doppler-US parameters between patent and dysfunctioning shunts. In patent shunts, the mean velocity within the portal vein was significantly higher but the performance of Doppler-US was not accurate enough to predict shunt dysfunction. In conclusion, the improvement in TIPS patency by using covered prostheses is maintained over time with a decreased risk of encephalopathy, while the risk of death was not increased.

Abstract
Fulminant hepatitis E has not been well characterized in industrialized countries. The aim of this study was to prospectively describe patients with acute hepatitis E presenting as fulminant hepatic failure, i.e. with encephalopathy and prothrombin index <50%. Between February 1997 and April 2005, seven patients with encephalopathy were diagnosed with acute hepatitis E using viral RNA detection. These patients were compared with 33 patients diagnosed with a mild form (absence of encephalopathy) of acute hepatitis E during the same time period. Patients were 65 +/- 11 years old. Five were active drinkers and six had chronic liver disease. All hepatitis E virus sequences evaluated (5/7) were of genotype 3. All patients but two died (71%). Four patients had no travel history. When compared with patients with a mild form of acute hepatitis E, active alcohol abuse and chronic liver disease were more frequent in patients with the severe form. Duration of hospitalization was longer. Aspartate transferase and bilirubin levels were significantly higher. Prothrombin index and accelerin levels were lower and death was more frequent. Acute nontravel-associated hepatitis E can appear as fulminant hepatitis with encephalopathy and coagulation disorders. Prognosis is severe and this may be due to the age at which it occurs and frequent underlying chronic liver disease.

Abstract
Hepatocellular carcinoma (HCC) is a major public health concern because of the absence of early diagnosis and effective treatments. Efficient diagnosis modalities and therapies to treat HCC are needed. Kruppel-like factor (KLF) family members, such as KLF6, are involved in cell proliferation and differentiation. KLF6 is inactivated in solid tumors, which may contribute to pathogenesis. However, KLF6 status in HCC is controversial. Thus, we undertook the characterization of KLF6 expression and function in HCC and HCC-derived cell lines. We found that HCC, HepG2 and HuH7 cells expressed KLF6 messenger ribonucleic acid and protein. Next, using RNA interference, we demonstrated that inhibiting KLF6 expression in vitro strongly impaired cell proliferation-induced G1-phase arrest, inhibited cyclin-dependent kinase 4 and cyclin D1 expression, and subsequent retinoblastoma phosphorylation. Finally, KLF6 silencing caused p53 upregulation and inhibited Bcl-xL expression, to induce cell death by apoptosis. Taken together, these data demonstrated that KLF6 is essential for HCC-derived cells to evade apoptosis.

Abstract
BACKGROUND Peritoneal carcinomatosis from pancreatic cancer has a poor prognosis with a median survival of 3.1 months. This is mainly due to lack of effective treatment. Interleukin 12 (IL12) is a proinflammatory cytokine that has a potent antitumoral effect by stimulating innate and adoptive immunity. AIM To examine the antitumoral effect and toxicity of intraperitoneal delivery of IL12 using an ex vivo gene therapy approach in a murine model of pancreatic peritoneal carcinomatosis. METHODS Peritoneal carcinomatosis was generated by direct intraperitoneal inoculation of the pancreatic cancer cell line Capan-1 in athymic mice. Syngenic fibroblasts were genetically modified in vitro to secrete IL12 using a polycistronic TFG murine IL12 retroviral vector coding for both p35 and p40 murine IL12 subunits. Ex vivo gene therapy involved injection of the genetically modified fibroblasts intraperitoneally twice a week for 4 weeks. RESULTS Treatment of pre-established peritoneal carcinomatosis with fibroblasts genetically modified to express IL12 induced a marked inhibition of tumour growth as measured by comparison of the weights of the intraperitoneal tumour nodules in the treated and control animals (3.52 (SD 0.47) v 0.93 (SD 0.21) g, p<0.05) and improved survival. This effect was associated with infiltration of the peritoneal tumour nodules with macrophages. Peritoneal lavage confirmed enhancement of the innate peritoneal inflammatory activity, with an increased number of activated macrophages and natural killer cells. Moreover, macrophages harvested from animals with peritoneal carcinomatosis and treated with IL12-expressing fibroblasts expressed an activated proinflammatory antitumoral M1 phenotype that included strongly enhanced reactive oxygen species and nitric oxide production. There was no treatment-related toxicity. CONCLUSION Multiple injections of genetically modified fibroblasts to express IL12 is an effective and well-tolerated treatment for experimental murine pancreatic peritoneal carcinomatosis via activated innate immunity and in particular activated M1 macrophages.

Abstract
Hepatitis C Virus (HCV) is classified into six genotypes. Genotype 4 is now spreading in Europe, especially among drug users, who are often infected with both HCV and the human immunodeficiency virus (HIV). Previous studies have shown that HCV-4 responds poorly to interferon. Pegylated interferon (peg-IFN) associated with ribavirin is now the most effective treatment for eradicating the virus. We have now studied the response of HCV-4 to peg-IFN and ribavirin and investigated the influence of HIV infection on anti-HCV therapy. Twenty-eight patients infected with HCV-4 were given peg-IFN plus ribavirin for 48 weeks. Patients infected with HCV alone tended to have a better initial response (66%) than patients infected with both HCV and HIV (30%, P = 0.06) and eradication was better (50%) than in doubly infected patients (15%, P = 0.06). After controlling for major factors influencing virus response, the virus response 12 weeks after the beginning of treatment in patients infected with HCV-4 (50%) was similar to that of patients infected with genotype 1 (53%) and lower than that of patients infected with genotypes 2 or 3 (82%, P < 0.05). The response 24 weeks after the end of therapy in patients infected with HCV-4 (32%) was similar to that of patients infected with HCV-1 (28%) and lower than that of patients with HCV-2 or HCV-3 (62% P < 0.05). These results indicate that HCV-4 patients should be considered to be difficult-to-treat.

Abstract
A total of 431 consecutive patients from the Midi Pyrenees area with acute hepatitis with unknown etiology in 2001-2002 were tested for the presence of immunoglobulin G-class (IgG) anti-hepatitis E virus (HEV) antibodies. Forty-six (10.7%) had anti-HEV IgG, and the results were questionable for a further 17 (3.9%). Real time PCR based on TaqMan detection was used to identify HEV genome fragments in the serum of patients with positive or questionable anti-HEV serology. HEV RNA was found in 25.4% of cases. All amplification products were sequenced and analyzed. Phylogenetic analysis revealed that all the strains were genotype 3. In conclusion, virological and epidemiological data indicate that genotype 3 viruses are circulating in the south west part of France (Midi-Pyrenees) in patients with acute hepatitis and who have not visited recently areas in which HEV is endemic.

Abstract
Hepatitis E is an acute and self-limiting hepatitis, and the causative agent, hepatitis E virus, is excreted in feces and orally transmitted. The disease is common in Asia and Africa, causing outbreaks or sporadic cases. In Europe, the infection is generally observed after a history of travel in an area of endemicity. We report on an autochthonous case in southwestern France in which the diagnosis was based on molecular tools rather than serological testing.

Abstract
Twenty-six patients living in the Midi-Pyrenees region of France who were infected with hepatitis C virus (HCV) genotype 5 were investigated. Most of these patients were of advanced age and had been infected nosocomially or by blood transfusion. Our case-control study, in which we treated patients with interferon- alpha plus ribavirin, indicated that, 24 weeks after the beginning of treatment, the virus response in patients infected with HCV genotype 5 was better than that in patients infected with HCV genotype 1 (100% of patients negative for detectable HCV RNA vs. 36.3%, respectively; P < .01); furthermore, 48 weeks after the end of treatment, the virus response in patients infected with HCV genotype 5 was better than that in patients infected with HCV genotype 1 (63.6% vs. 22.7%, respectively; P < .05) and was similar to that in patients infected with HCV genotype 2 or 3 (66.6%). These results show that HCV genotype 5 might have good intrinsic sensitivity to combination therapy with interferon- alpha plus ribavirin.

Abstract
BACKGROUND & AIMS A 50% dysfunction rate at 1 year is one of the main drawbacks of the transjugular intrahepatic portosystemic shunt procedure. Preliminary experimental and clinical studies suggest that the use of stents covered with polytetrafluoroethylene could tremendously decrease this risk. METHODS Eighty patients with cirrhosis and uncontrolled bleeding (n = 23), recurrent bleeding (n = 25), or refractory ascites (n = 32) were randomized to be treated by transjugular intrahepatic portosystemic shunts with either a polytetrafluoroethylene-covered stent (group 1; 39 patients) or a usual uncovered prosthesis (group 2; 41 patients). Follow-up Doppler ultrasound was scheduled at day 7, at 1 month, and then every 3 months for 2 years. Angiography and portosystemic pressure gradient measurements were performed 6, 12, and 24 months after the transjugular intrahepatic portosystemic shunt procedure and whenever dysfunction was suspected. Dysfunction was defined as a >50% reduction of the lumen of the shunt at angiography or a portosystemic pressure gradient >12 mm Hg. RESULTS After a median follow-up of 300 days, 5 patients (13%) in group 1 and 18 (44%) in group 2 experienced shunt dysfunction (P < 0.001). Clinical relapse occurred in 3 patients (8%) in group 1 and 12 (29%) in group 2 (P < 0.05). Actuarial rates of encephalopathy were 21% in group 1 and 41% in group 2 at 1 year (not significant). Estimated probabilities of survival were 71% and 60% at 1 year and 65% and 41% at 2 years in groups 1 and 2, respectively (not significant). CONCLUSIONS The use of polytetrafluoroethylene-covered prostheses improves transjugular intrahepatic portosystemic shunt patency and decreases the number of clinical relapses and reinterventions without increasing the risk of encephalopathy.

Abstract
OBJECTIVES Reactive oxygen species may be involved in the pathogenesis of chronic hepatitis C virus infection. Metallothionein (MT) is an essential protein for the protection of cells against reactive oxygen species. The aim of this prospective study was to assess the influence of the hepatic level and cellular distribution of MT in hepatitis C virus (HCV) infection and in the liver disease outcome. METHODS In liver biopsy samples of 32 patients with chronic HCV infection and of 12 control subjects, quantification of MT was performed by radioimmunoassay, MT, interleukin (IL)-1 and -6, and tumor necrosis factor (INF)-alpha mRNA by reverse transcription-polymerase chain reaction (PCR) and cellular distribution by immunohistochemistry. RESULTS In HCV-infected patients, MT liver protein level was 3-fold lower than in control specimens. A significant inverse linear regression between MT protein or mRNA expression and the Histological Activity Index, the necroinflammatory grade, and the stage of fibrosis was observed. MT immunostaining was located in the nucleus and cytoplasm in hepatocytes of control subjects, whereas it was mainly cytoplasmic in HCV-infected patients. Before interferon (IFN) therapy, the hepatic MT level in patients that were nonsustained responders was half that of sustained responders. Intrahepatic IL-6 and MT were simultaneously down-regulated, but no correlation was found between MT and intrahepatic cytokine mRNA expression in patients with chronic HCV infection. CONCLUSIONS This study shows that hepatic MT expression could reflect the severity of chronic HCV infection and could be one of the factors associated with a favorable clinical outcome in the response to interferon therapy.

Abstract
BACKGROUND One third of French elite road cyclists were found to have hyperferritinemia on antidoping control tests performed during the Tour de France in 1998. PURPOSE This study was undertaken to determine whether hyperferritinemia corresponded to elevated body iron stores or not and, affirmatively, what were its mechanism, its clinical consequences, and its spontaneous course. METHODS 83 elite road male cyclists presenting with hyperferritinemia, defined as serum ferritin level greater than 300 microg.L-1, were studied with respect to consumption of iron and other drugs, serum iron tests, HFE mutations, and hepatic iron concentration (HIC; N < 35 micromol.g-1 dry weight). RESULTS All cyclists were asymptomatic and had normal physical and cardiac examination. Their median (range) serum ferritin, serum iron, and transferrin saturation levels were 504 microg.L-1 (306-1671), 20 micromol.L-1 (8.5-36.3), and 39% (20-76), respectively. HIC was increased in 24/27 up to 187 micromol.g-1. Allelic frequency of the H63D mutation was increased in cyclists when compared to controls (P = 0.04). However, iron tests did not differ according to HFE genotypes. Most cyclists (89%) had been supplemented with iron. The median iron supplementation was 25.5 g (range: 1.4-336) and correlated well (P = 0.002) with serum ferritin. Evolution of serum ferritin levels did not differ whether cyclists had been continuing iron supplementation or not. CONCLUSION Hyperferritinemia in elite road cyclists accounted for increased body iron stores caused by and persisting after cessation of excessive iron supplementation. Even when mild, iron excess may expose to long-term complications and should be removed, at least at the time when professional cyclists retire. To prevent iatrogenic iron overload, supplementation with iron must be done according to serum ferritin follow-up and not either blindly or on the basis of serum iron determination only.

SUBJECTS AND METHODS Twenty cirrhotic patients (57 +/- 11 years old) admitted with a history of esophageal variceal bleeding (n = 11), refractory ascites (n = 5), or both (n = 4) were included. Five of the patients were treated for TIPS revision, and 15 as de novo TIPS placements. The endoprostheses used were composed of a 2-cm noncovered nitinol stent and a 4- to 8-cm expanded-polytetrafluoroethylene graft covering, and were placed from the portal vein to the ostium of the hepatic vein. Patients underwent Doppler sonography at discharge and again at 1, 3, 6, 9, 12, and 15 months and underwent venography with portosystemic pressure gradient measurement at 6 months and whenever necessary. RESULTS At the time of this writing, complications included three TIPS restenoses and one recurrent ascites successfully treated by balloon dilation, two cases of segmentary liver ischemia, and one patient with encephalopathy that required shunt reduction. After TIPS placement, the portosystemic pressure gradient dropped from 18 +/- 5 to 5 +/- 4 mm Hg. Primary and secondary patency rates were 80% and 100%, respectively, at 387 days. CONCLUSION These results clearly show the feasibility of TIPS placement with the Gore TIPS endoprosthesis stent-graft and its improved patency compared with results in the literature for bare stents. These preliminary results must be certified further with randomized comparative trials between covered and noncovered TIPS stents.

Abstract
BACKGROUND/AIMS Our aim was to assess whether histological response was improved by continuing interferon-alpha (IFN) treatment in patients with chronic hepatitis C (HCV) with a biochemical response and no viral clearance after a usual IFN treatment. METHODS Fifty-seven patients with normal alanine aminotransferase (ALAT) levels and positive HCV RNA at the end of a 1 year IFN treatment were randomly assigned to either group 1 (n = 28) where IFN was stopped, or group 2 (n = 29) where IFN was continued for 1 more year with gradual reduction of the dose to keep serum ALAT activity below the upper limit of normal. Liver biopsies were obtained before, and then 6 months after the end of treatment. RESULTS Knodell's index improved between paired biopsies in group 2 (8.2+/-2.4 vs. 5.5+/-2.1), but not in group 1 (8+/-2.3 vs. 6.5+/-2). In post-treatment biopsies, the METAVIR activity score was significantly lower in group 2 than in group 1 (0.7+/-0.2 vs. 1.1+/-0.3, P < 0.05). In group 2, an improvement of the METAVIR fibrosis score was observed (1.3+/-0.4 vs. 1.1+/-0.2), whereas fibrosis progressed in group 1 (1.3+/-0.4 vs. 1.6+/-0.4). CONCLUSIONS Maintenance therapy by the minimal dose of IFN able to maintain biochemical response prevents histological progression in the sub-group of patients without virological response.

Abstract
It has been shown that oxidative stress occurs in chronic hepatitis C. Release of reactive oxygen species (ROS) from sequestered phagocytes and activated resident macrophages represents the predominant component of oxidative stress in the liver. However, little is known about the ability of the monocyte to produce ROS in response to protein of hepatitis C virus. In this study, we investigated the ROS production in human monocytes stimulated by several viral proteins of hepatitis C virus. Human monocytes from healthy blood donors were incubated with recombinant viral protein: Core, NS3, NS4, and NS5. ROS production was measured by chemiluminescence. Only NS3 triggered ROS production in human monocytes. Generated ROS were mainly the anion superoxide. NS3 also induced a rapid and transient increase in intracellular calcium concentration measured by a video digital microscopy technique. By using different metabolic inhibitors, we showed that ROS production requires calcium influx, tyrosine kinases, and the stress-activated protein kinase, p38. The study of p47(PHOX) phosphorylation and translocation showed that NADPH oxidase was activated and involved in ROS production induced by NS3. In a second experiment, NS3 inhibited the oxidative burst induced by phorbol 12-myristate 13-acetate. These results indicate that NS3 activates NADPH oxidase and modulates ROS production, which may be involved in the natural history of hepatitis C infection.

Abstract
OBJECTIVE AND DESIGN The aim of the present study was to characterize during acute and chronic liver injury induced by CCl4, macrophage phenotypes and whether a change in reactive oxygen intermediates (ROI) and eicosanoids production by Kupffer cells (KC) was observed. MATERIAL AND METHODS Liver steato-necrosis and cirrhosis were induced in rats after 3 weeks and 9 weeks of CCl4 intoxication, respectively. Monocytes and tissue macrophages were identified by immunohistochemical study using monoclonal antibodies ED-1 and tissue macrophages using the antibody ED-2. The release of ROI and eicosanoids in response to the phorbol ester TPA (protein kinase activator) and to the calcium ionophore A23187 was assessed in cultivated cells. RESULTS As compared to healthy controls, livers of rats with steato-necrosis or cirrhosis exhibited a significant increase of ED-1 and ED-2 positive cells. Only KC from rats with liver steato-necrosis were found to have higher A23187, TPA + A23187 or opsonized zymosan induced ROI production than healthy controls (p < 0.01). After TPA + A23187 or opsonized zymosan stimulation, KC from both rats with steato-necrosis or cirrhosis produced more TxB2 and leukotrienes and less PGE2 as compared to healthy controls (p <0.05). CONCLUSIONS These results suggest an influx of monocytes into the liver during acute and chronic injury induced by CCl4. Functional changes of this inflammatory infiltrate have been demonstrated with an increase of ROI production only in the early stage of liver injury whereas a rise in KC leukotriene production and an imbalance between cytoprotective and cytotoxic prostanoids were observed at all stages of liver disease.

Abstract
BACKGROUND/AIMS This study aimed to evaluate the Baveno II criteria defining key events in variceal bleeding. METHODS These criteria were applied to 196 patients with cirrhosis admitted for upper gastrointestinal bleeding due to portal hypertension and enrolled in a trial. Blood pressure, heart rate, hematocrit and clinical signs of upper digestive tract hemorrhage were recorded for 5 days. The blind overall clinical judgment of hemodynamic stability was recorded separately by the Steering Committee. RESULTS The evaluation of several hemodynamic criteria was left to the judgment of the clinician. The first time point for the control of bleeding, fixed at 6 h after admission, was impractical since 13% of the patients had not yet received specific treatment. The independent judgment did not agree in 38% of 82 cases without control of bleeding. In 15% of cases this was due to tachycardia. Calculation of several judgment criteria was not defined in the Baveno II criteria: survival without bleeding at 5 days, transfusion rate, and length of hospital stay. CONCLUSIONS Although the Baveno II criteria have improved the definitions of key events, the criteria are hampered by limits such as false positive criteria of failure to control bleeding. We make several proposals for improvement.

Abstract
PURPOSE To assess the efficacy, morbidity, and mortality involved in the creation of transjugular intrahepatic portosystemic shunts (TIPS) in the treatment of patients with refractory ascites in Child-Pugh classes B and C. MATERIALS AND METHODS Forty-eight consecutive patients with refractory ascites were treated with TIPS creation in a tertiary care institution. They were followed for a median of 337 days (range, 3-1376 d). RESULTS TIPS significantly decreased the portohepatic pressure gradient (20.7 +/- 5.9 mm Hg vs. 6.8 +/- 4.1 mm Hg; P < .0001). Seventy-three percent of patients had complete or partial response. One year after TIPS creation, survival was 73% in Child class B patients and 56% in Child class C patients. Thirteen patients experienced procedural complications (portal vein thrombosis, peritoneal bleeding, acute renal failure, pneumothorax, hemoptysis, spontaneous bacterial peritonitis, and heart failure) and TIPS creation was considered the cause of death in five patients (10.4%). Primary patency was 65% at 3 months and 23% at 1 year, but shunt obstruction was accessible for a second intervention. Ten patients (21%) had de novo encephalopathy after TIPS creation. CONCLUSIONS This series suggests that TIPS is an effective treatment for refractory ascites; however, it is a challenging procedure and serious complications--usually renal and heart failure--can be seen. A careful selection of patients is mandatory.

Abstract
Failure to control bleeding and early rebleeding account for the high mortality associated with variceal hemorrhage in cirrhosis. We compared endoscopic sclerotherapy to terlipressin, a drug that effectively controls acute bleeding while reducing in-hospital mortality. This multicenter randomized controlled trial included 219 cirrhotic patients admitted for endoscopy-proven acute variceal bleeding and randomized to receive repeated injections of terlipressin during 6 days (n = 105) or emergency sclerotherapy (n = 114). Success was defined as obtaining control of bleeding (24-hour bleeding-free period during the first 48 hours) and lack of early rebleeding (any further bleeding from initial control to 5 days later) and survival during the study. Both groups were similar at inclusion. Failure rate for terlipressin was 33% and 32% for sclerotherapy (not significant [NS]). Early rebleeding was responsible for 43% and 44% of failures, respectively. This high efficacy was observed in both Child-Pugh class A + B and Child-Pugh class C patients. Both treatments were similar regarding transfusion requirements, in-hospital stay, and 6-week mortality (26 vs. 19 patients). Side effects appeared in 20% of patients receiving terlipressin and in 30% of those on sclerotherapy (P =.06); being serious in 4% and 7%, respectively (NS). In conclusion, terlipressin and sclerotherapy are equally highly effective therapies achieving the initial control of variceal bleeding and preventing early rebleeding. Both treatments are safe, but terlipressin is better tolerated. Therefore, terlipressin may represent a first-line treatment in acute variceal bleeding until the administration of elective therapy, especially in hospitals where a skilled endoscopist is not available 24 hours a day.

Abstract
Epidemiologic parameters, virologic characteristics and frequency of HLA class II DR and DQ antigens were compared between 63 subjects with spontaneous hepatitis C virus clearance (group 1) and 282 patients with chronic active hepatitis C virus infection (group 2). DRB1*1101 and moreover DQB1*0301 alleles were more frequent in group 1 than in group 2 (33.8% vs. 14.7% and 64.4% vs. 28.6%; P=0.012 and P=0.003, respectively). The frequency of DQB1*02 was lower in group 1 than in group 2 (25.4% vs. 49%; P=0.04). No difference was observed in viral genotype distribution between group 1 and group 2. Univariate analysis showed that female sex and contamination by intravenous drug use were associated with self limited infection. However, by multivariate analysis, the only independent factor associated with hepatitis C virus RNA clearance was female sex (P=0.004). In conclusion, spontaneous hepatitis C virus RNA clearance is determined by class II antigens (mainly DQB1*0301) and female sex, while viral genotype plays no role.

Abstract
Hepatitis C virus (HCV) populations persist in vivo as a mixture of heterogeneous viruses called quasispecies. The relationship between the genetic heterogeneity of these variants and their responses to antiviral treatment remains to be elucidated. We have studied 26 virus strains to determine the influence of hypervariable region 1 (HVR-1) of the HCV genome on the effectiveness of alpha interferon (IFN-alpha) therapy. Following PCR amplification, we cloned and sequenced HVR-1. Pretreatment serum samples from 13 individuals with chronic hepatitis C whose virus was subsequently eradicated by treatment were compared with samples from 13 nonresponders matched according to the major factors known to influence the response, i.e., sex, genotype, and pretreatment serum HCV RNA concentration. The degree of virus variation was assessed by analyzing 20 clones per sample and by calculating nucleotide sequence entropy (complexity) and genetic distances (diversity). Types of mutational changes were also determined by calculating nonsynonymous substitutions per nonsynonymous site (K(a)) and synonymous substitutions per synonymous site (K(s)). The paired-comparison analysis of the nucleotide sequence entropy and genetic distance showed no statistical differences between responders and nonresponders. By contrast, nonsynonymous substitutions were more frequent than synonymous substitutions (P </= 0.05) in responders, but there was no significant difference in nonresponders. Nonsynonymous substitutions tended to be more frequent than synonymous substitutions in women (P = 0.06) but not in men. Nucleotide entropy and genetic distances were significantly related to serum RNA concentration (P </= 0.01). Our findings suggest that after controlling for the major determinants of interferon response, neither complexity nor diversity of the HVR-1 region is associated per se with virus eradication. Because a higher proportion of nonsynonymous substitutions than synonymous substitutions was found only in responders, host anti-HCV-specific immune response rather than viral factors may be playing an important role in the interferon response.

Abstract
The optimal management of ruptured gastric varices in patients with cirrhosis has not been codified yet. The present study reports the use of transjugular intrahepatic portosystemic shunt (TIPS) in patients with refractory gastric variceal bleeding. Thirty-two consecutive patients were included. All had been unresponsive to vasoactive agents infusion, sclerotherapy, and/or tamponade and were considered poor surgical candidates. They were followed-up until death, transplantation, or at least 1 year (median: 509 days; range 4 to 2,230). Hemostasis was achieved in 18 out of 20 patients actively bleeding at the time of the procedure. In the whole sample of 32 patients, rebleeding rates were 14%, 26%, and 31%, respectively at 1 month, 6 months, and 1 year. De novo encephalopathy was observed in 5 (16%) patients. Seven patients experienced complications and consequently 4 of these patients died. TIPS primary patency rates were 84%, 74%, and 51%, respectively, at 1 month, 6 months, and 1 year. For the same periods of time, survival rates were 75%, 62%, and 59%. These results suggest that TIPS can be used in cirrhotic patients with refractory gastric variceal bleeding and are effective in achieving hemostasis as well as in preventing rebleeding.

Abstract
In liver injury induced by carbon tetrachloride, secondary hepatic injury occurs from inflammatory processes originating from products released by activated Kupffer cells, which play a central role in hepatic inflammation. The purpose of our study was to demonstrate, in rats, the relationships between a function of the hepatic macrophages, TNF-alpha production and the state of activation of these cells, characterized by their phenotype, in the different phases of the process and development of fibrosis in a carbon tetrachloride-induced cirrhosis model. The immunohistochemical localization of proinflammatory cytokine TNF-alpha and surface surface makers (ED1 and ED2) was studied in hepatitis and cirrhosis in response to 3 and 9 weeks ingestion of carbon tetrachloride. After carbon tetrachloride ingestion, accompanying the increased necrosis, immunohistochemical analysis of liver tissue sections demonstrated the significantly increased number of cells expressing ED1, ED2 and TNF-alpha, compared to normal. The number of cells expressing the surface phenotypic markers of liver macrophages increased and this change was concomitantly associated with an increased cellular expression of TNF-alpha. Local macrophage proliferation and influx of newly recruited blood monocytes resulted in an increase of the macrophage population. The populational changes involved difference in functional activity and enhanced TNF-alpha expression. This cytokine expressed in the carbon tetrachloride-induced inflammatory process is associated with the development of fibrosis and may contribute to disease severity.

Abstract
OBJECTIVE The aim of the study was to determine the influence of HLA class II genes on the response to interferon-alpha (IFN-alpha) in patients with chronic hepatitis C. METHODS The distribution of HLA DRB1 and DQB1 alleles was assessed in 170 caucasoïd patients treated with IFN-alpha for chronic hepatitis C. 50 patients had a long term sustained response to treatment whereas 120 patients were nonresponders. RESULTS Female sex, non-1 HCV genotype particularly genotype 2 and pretreatment low serum HCV RNA level were associated with long-term sustained response to IFN-alpha. A trend towards a higher prevalence of DRB1*07 allele in non responders than in patients with sustained response (45% vs. 28%, odds ratio 2.1; P < 0.05) on the one hand and of DQB1*06 allele in HCV genotype 1 patients with sustained response than in HCV genotype 1 nonresponders (75% vs 27.3%, odds ration 7.9; P < 0.02) on the other hand, were observed. However, none of these two differences remained significant after Bonferroni's correction. CONCLUSION Accordingly, we conclude that the response to IFN-alpha therapy is more tightly related to virus factors than to host's HLA class II genes.

Abstract
PURPOSE To assess whether the use of a prosthesis covered by a Dacron sheath might prevent pseudointimal hyperplasia in a transjugular intrahepatic portosystemic shunt (TIPS). MATERIALS AND METHODS A TIPS procedure was performed in nine pigs, after creation of a portal vein microembolization model of portal hypertension, by using a Dacron-covered nitinol stent. The first centimeter on the lower extremity of this specially made prototype was uncovered, to avoid portal vein thrombosis. Three weeks later, the seven surviving animals underwent transjugular hemodynamic and angiographic follow-up and were then killed for gross and histologic evaluation. RESULTS Shunt insertion was possible in all pigs; two died of complications of the procedure. After 3 weeks only two shunts were patent, although a 50%-60% narrowing of the initial portion of the shunt was present; the remaining shunts were occluded. Histologic examination showed pseudointimal hyperplasia associated, in the cases of occlusion, with a luminal thrombosis. CONCLUSION This Dacron-covered stent did not prevent pseudointima formation over the stent and resulted in a high early occlusion rate, probably related to a pronounced tissue fibrotic response likely due to Dacron-induced inflammation.

Abstract
Ascites and hepatocellular carcinoma are frequently associated. We evaluated the usefulness of alpha-fetoprotein assay in ascitic fluid versus the serum assay, for the diagnosis of hepatocellular carcinoma, in 125 patients with peritoneal effusions (31 patients with hepatocellular carcinoma, 14 with extra-hepatic malignancies and 80 with a benign effusion). Albumin and total protein were also assayed and cytological analysis of the ascitic fluid performed. Alpha-fetoprotein appeared to be lower in ascitic fluid than in serum. For a diagnostic specificity of 95%, the thresholds were 18.9 microg/l in serum and 4 microg/l in ascitic fluid and the diagnostic sensitivity of alpha-fetoprotein was identical in serum and ascitic fluid (67.7%). Various ratios between alpha-fetoprotein and albumin or total protein did not enhance the diagnostic performance. Thus alpha-fetoprotein concentration in ascitic fluid reflected the serum concentration and proved to be of similar value for the diagnosis of hepatocellular carcinoma, providing that the appropriate thresholds are considered.
