Abstract
BACKGROUND Liver iron deposits are frequent in viral C cirrhotic patients but their role is not well defined. AIMS To investigate the effect of liver iron excess on the prevalence of hepatocellular carcinoma (HCC) in patients with viral C cirrhosis. METHODS Hepatic iron was evaluated retrospectively using a semiquantitative method in liver biopsies of 104 viral C cirrhotic patients, 48 with HCC and 56 controls (HCC free). Corrected total iron score (0-60) was defined by the sum of three scores: hepatocytic iron score (0-36), sinusoidal iron score (0-12), and portal iron score (0-12), multiplied by 3/3, 2/3, or 1/3 according to the heterogeneous iron localisation in the nodules. RESULTS After adjustment for known risk factors for HCC, regression analysis showed that iron deposits (corrected total iron score >0) were more frequent in HCC patients than in controls (odds ratio 4.94; 95% confidence interval 1.59-15. 32; p=0.0056). The median of corrected total iron score was significantly higher in HCC patients than in controls (odds ratio 1. 092; 95% confidence interval 1.01-1.13; p=0.021). This liver iron overload was sinusoidal (odds ratio 5.2; 95% confidence interval 1. 82-15.11; p=0.0022). CONCLUSIONS Liver iron deposition was more frequent and more important in viral C cirrhotic patients with HCC than in HCC free controls. Liver iron overload seems to contribute to the development of HCC in patients with viral C cirrhosis.

Abstract
Drug-induced liver injuries make up a persisting and challenging problem for physicians, health agencies and pharmaceutical firms. The clinical expression is polymorphous, acute hepatitis being predominant. The diagnosis is frequently difficult because of the absence of specific signs in most cases and mainly relies on the exclusion of other causes. The diagnosis should be particularly evoked in patients over 50 yr who are taking many drugs, after viral infections have been ruled out. Acute hepatocellular hepatitis is particularly severe because of the risk of fulminant hepatitis or of a more insidious course leading to cirrhosis. Cross hepatotoxicity can sometimes occur. One should avoid re-administration of not only the causative agents but also of other drugs belonging to the same family or having a related chemical structure. The prediction of the hepatotoxicity of new drugs must be improved. Investigations would be particularly useful for drugs having critical chemical structures and belonging to families with an established history of hepatotoxicity.

Abstract
OBJECTIVES To report the validation of 2 questionnaires of quality of life in chronic hepatitis C and the first results in 100 patients. METHODS The questionnaire included 118 items and took 30 to 45 minutes to answer. It included a general index, the Nottingham Health Profile, with 38 items in 6 themes (physical mobility, social isolation, emotional reactions, pain, sleep and energy) and a specific index, the Montpellier Specific Index, with 80 items in 7 themes: symptoms, food, alcohol and tobacco, work, relations with other people, perception of disease. RESULTS The questionnaires were self-administered to the 100 first patients with chronic hepatitis C without cirrhosis before treatment; 55 men, 45 women, average age 40 year-old, median Knodell's score 8 and median METAVIR score A2 F1. Reduction in the quality of life was frequent and was not highly correlated with biological, virological and histological parameters; it was associated with psychological disorders, reduced sexuality and apprehension of the future. CONCLUSION This study showed the feasibility, validation, sensitivity and agreement of a quality of life questionnaire, which included a general index and a specific index of chronic hepatitis C in France. These initial results must be confirmed in studies during antiviral treatment of patients.

Abstract
BACKGROUND/AIMS Alcoholic cirrhosis remains a controversial indication for liver transplantation, mainly because of ethical considerations related to the shortage of donor livers. The aim of this study was to review experience to date, focusing on survival rates and complications, and the effect of alcohol relapse on outcome and alterations in marital and socioprofessional status. METHODS The results for 53 patients transplanted for alcoholic cirrhosis between 1989 and 1994 were compared with those for 48 patients transplanted for non-alcoholic liver disease. The following variables were analysed: survival, rejection, infection, cancer, retransplantation, employment and marital status, alcoholic recurrence. The same variables were compared between alcohol relapsers and non-relapsers. RESULTS Recovery of employment was the only significantly different variable between alcoholic (30%) and non-alcoholic patients (60%). Two factors influenced survival in the absence of alcohol recidivism: age and abstinence before transplantation. For all other variables, there were no differences between alcoholic and non-alcoholic patients, and, within the alcoholic group, between relapsers and non-relapsers. The recidivism rate was 32%. CONCLUSION The data indicate that liver transplantation is justified for alcoholic cirrhosis, even in cases of recidivism, which did no affect survival and compliance with the immunosuppressive regimen. These good results should help in educating the general population about alcoholic disease.

Abstract
BACKGROUND/AIM Fifty percent of patients infected with hepatitis C virus (HCV) show no response to alpha-interferon, and no alternative therapy has thus far proven to be effective. Therapeutic combination with ribavirin and alpha-interferon has shown promising results in naive patients and in relapsers, but based on limited series, it was reported to be inefficient in non-responders. The aim of our study was therefore to explore and compare, in a randomized trial, the tolerance and potential efficacy of alpha-interferon alone with a sequential combination of ribavirin and the same alpha-interferon regimen in those patients. METHODS Sixty-four non-responder patients were randomized in the alpha2b-interferon group (a 6-month course at a dosage of 6 MU followed by a 6-month course of 3 MU three times weekly subcutaneously) and 62 in the "combination" group (sequential combination of the same alpha2b-interferon therapy preceded by a 2-month course of ribavirin which was then associated for 2 months with alpha2b-interferon at a daily dosage of 1.0 or 1.2 g). RESULTS Treatment withdrawal was necessary for six patients from the alpha-interferon and eight patients from the combination group. Normalization of aminotransferase activities was significantly more frequent after the 4-month course of ribavirin with 2 months of interferon than after 2 months of interferon alone (52.8 vs. 26.2%, p<0.01), but this difference was not maintained after ribavirin withdrawal. Disappearance of serum HCV RNA (PCR) was significantly more frequent at the end of treatment in the combination group (24.5 vs. 7.7%, p=0.02), but did not differ 6 months after the end of therapy (9.8 and 8.3%, respectively). The long-term response was not associated with liver status (cirrhosis vs. absence of cirrhosis) or genotype. Mean viremia was significantly lower in long-term responders than in non-responders or relapsers in both groups (p<0.001 for the interferon group and p<0.05 for the combination group), but the large extent of viral load precluded reliable prediction. The pre- and post-treatment hepatitis activity index did not differ between the two groups. While a crude histopathological improvement in the hepatitis activity index for a given patient was more frequently observed in the combination group (69.2 vs. 35.9%, p<0.01), improvement as defined by a decrease of at least 2 in the hepatitis activity index was significant only for lobular necrosis and degeneration. CONCLUSIONS This study demonstrates the efficacy of the combination of ribavirin/alpha-interferon in non-responders. Indeed, (i) it is fairly tolerated; (ii) it increases the rate of the initial biological response, and of the virological response by decreasing breakthrough, though this benefit is not sustained; and (iii) it induces a significant histological improvement in necrosis. A simultaneous and prolonged combination of ribavirin/alpha-interferon should be further evaluated in non-responders.

Abstract
OBJECTIVES To study the frequency of tumor seeding after percutaneous biopsy of hepatocellular carcinoma and to evaluate the impact on long-term survival. METHODS Records of 150 patients with cirrhosis who underwent ultrasound-guided aspiration biopsy for hepatocellular carcinoma between 1989 and 1996 were reviewed in June 1998. Liver transplantation was performed in 7 patients. One to three needle passes were performed with 18 to 20 gauge needles. Follow-up included regular clinical examinations and ultrasonography or computerized tomography. RESULTS Four cases (2.66%) of subcutaneous metastasis were noted at the needle insertion site; none in transplanted patients. All patients had viral cirrhosis, Okuda class I. Nodules were detected 4, 12, 22 and 24 months after biopsy. The second patient is alive 24 months after tumor seeding. For other patients, survival time was 4, 24 and 60 months respectively, without local tumor extension after surgical resection or radiotherapy. During a mean 11.8 months of follow-up, 127 patients died without tumor seeding. Eleven patients are still being followed and have no signs of needle tract implantation of hepatocellular carcinoma (mean follow-up 34.7 months). CONCLUSION The prevalence of tumoral seeding after percutaneous biopsy of hepatocellular carcinoma was 2.66%, which is higher than in previous studies. After liver transplantation, no evidence of needle tract seeding was identified. Survival did not seem to be influenced by local evolution.

Abstract
Riluzole is a new drug representing the first active treatment for amyotrophic lateral sclerosis. We report the cases of two patients who developed acute hepatitis after taking riluzole at the recommended dose (100 mg daily) for 7 and 4 weeks, respectively. In both cases, liver histology showed hepatocellular damage with inflammatory infiltration and microvesicular steatosis without fibrosis. Liver enzymes returned to normal 4 and 8 weeks, respectively, after riluzole withdrawal. In one case, the readministration of riluzole was followed by the relapse of hepatitis. These two observations strongly suggest that riluzole can induce acute hepatitis with associated hepatocellular damage and microvesicular steatosis. They also suggest that liver enzymes should be monitored during treatment with riluzole.

Abstract
BACKGROUND/AIMS Bacterial infections, specially Staphylococcus aureus (S. aureus) septicemia, remain a leading cause of death following liver transplantation. It has been demonstrated that nasal carriage of S. aureus is associated with invasive infections in patients undergoing hemodialysis and could be decreased by use of antibiotic nasal ointment. However, in cirrhotic patients, the frequency of nasal carriage is unknown. The aims of this study were to determine the prevalence of S. aureus nasal carriage in cirrhotic patients and to assess nosocomial contamination. METHODS One hundred and four patients were included in a prospective study, 52 cirrhotic and 52 control (hospitalized patients without cirrhosis or disease which might increase the rate of nasal carriage of S. aureus). On admission and after a few days of hospitalization, nasal specimens from each anterior naris were obtained for culture. S. aureus was identified by the gram strain, positive catalase and coagulase reactions; antibiotic susceptibility was determined using a disk-diffusion test. RESULTS Both groups were similar with regard to age and sex. The prevalence of nasal colonization on hospital admission was 56% in cirrhotic patients and 13% in control patients (p = 0.001). After an average of 4 days, 42% of cirrhotics and 8% of control patients were colonized (p = 0.001), without any nosocomial contamination. Three strains out of 29 were oxacillin-resistant in cirrhotic patients, and none in controls (p>0.05). There was no statistical difference in carriage rate according to sex, age, cause of cirrhosis and Child-Pugh score. Previous hospitalization (OR, 6.3; 95% CI, 2.3 to 19.9; p = 0.0006) and cirrhosis (OR, 4.4; 95% CI, 1.5 to 13.4; p = 0.0048) were independent predictors of colonization. CONCLUSION Cirrhotic patients had a higher S. aureus nasal carriage rate than control subjects. Previous hospitalization and cirrhosis diagnosis were correlated to nasal colonization. Further studies are necessary to determine if nasal decontamination could reduce S. aureus infections after liver transplantation.

Abstract
The reasons for wide variations in the severity of recurrent hepatitis C after liver transplantation are unclear. We studied liver transplant recipients to assess the effect of hepatitis C virus (HCV) genotype and HCV RNA quantification on histologic progression of recurrent hepatitis C after transplantation. Twenty-five patients underwent transplantation for HCV cirrhosis and were followed up with virologic and histologic assessments for a mean of 51 months. HCV genotype was determined by line probe assay. HCV RNA was quantitated in serum samples by nested polymerase chain reaction. The HCV genotype 1 was detected in 17 patients and other genotypes in 8. Acute lobular hepatitis developed in 17 patients 162 days posttransplantation on average. Long-term biopsy specimens (mean, 51 months after the date of liver transplantation; range, 24-86 months) showed chronic hepatitis in 19 patients (mild, 5; moderate, 9; and severe, 5, 2 with extensive scarring). The serum alanine aminotransferase level was correlated with hepatocyte necrosis (piecemeal and lobular) but not with portal inflammation or fibrosis. Patients infected with genotype 1 had a higher Knodell score, and the 5 patients with severe hepatitis C all were infected with genotype 1. HCV RNA levels were significantly higher in patients with genotype 1 than in patients with other genotypes, as were the severity of histologic recurrence and levels of viral replication.

Abstract
In vitro infection of adult normal human hepatocytes in primary culture has been performed for investigating the replication cycle of hepatitis C virus (HCV) in differentiated cells. Hepatocytes were prepared from liver tissue resected from donors who tested negative for HCV, and inoculation was performed 3 days after plating with 33 HCV serum samples of different virus load and genotype. The presence of intracellular HCV RNA, detected by a strand-specific rTth RT-PCR assay, was used as evidence of infection. A kinetics analysis of HCV replication revealed that intracellular negative-strand RNA appeared at day 1 post-infection with a maximum level at days 3 and 5, followed by a decrease until day 14. At day 5, we estimated that the copy level of viral RNA was amplified at least 15-fold in infected cells. The level of intracellular HCV RNA in response to different serum samples was reproducible from one hepatocyte culture to another, suggesting that there is no inter-individual variability in the susceptibility of hepatocytes to HCV infection. These findings indicate that adult human hepatocytes in primary culture retain their susceptibility to in vitro HCV infection and support HCV RNA replication. This model should represent a valuable tool for the study of initial steps of the HCV replication cycle and for the evaluation of antiviral molecules.

Abstract
To determine the relationship between quantitative Doppler parameters of portal, hepatic, and splanchnic circulation and hepatic venous pressure gradient (HVPG), variceal size, and Child-Pugh class in patients with alcoholic cirrhosis, we studied forty patients with proved alcoholic cirrhosis who underwent Doppler ultrasonography, hepatic vein catheterization, and esophagoscopy. The following Doppler parameters were recorded: time-averaged mean blood velocity, volume flow of the main portal vein flow, and resistance index (RI) of the hepatic and of the superior mesenteric artery. Doppler findings were compared with HVPG, presence and size of esophageal varices, and Child-Pugh class. There was a significant inverse correlation between portal velocity and HVPG (r = -.69), as well as between portal vein flow and HVPG (r = -.58). No correlation was found between RI in the hepatic artery or superior mesenteric artery and HVPG. No correlation was found between portal vein measurements and presence and size of varices. Severe liver failure was associated with lower portal velocity and flow. In patients with alcoholic cirrhosis, only portal vein blood velocity and flow, but neither hepatic nor mesenteric artery RI, are correlated to the severity of portal hypertension and to the severity of liver failure.

Abstract
BACKGROUND/AIM The risk of adverse drug interactions with interferon-alpha has been poorly assessed. The aim of our study was to establish whether administration of interferon-alpha at therapeutic doses in patients with chronic hepatitis C may have significant inhibitory effects on other drug metabolism. The study was focused on cytochromes P-450 1A2 and 3A, two major isoforms involved in the metabolism of numerous substrates. METHODS Eighteen patients with chronic active hepatitis C requiring an interferon-alpha treatment were studied. Cytochrome P-450 1A2 activity was determined on the basis of an in vivo caffeine metabolism study. Cytochrome P-450 3A activity was determined according to in vivo cortisol metabolism into 6-beta-hydroxycortisol. Both activities were determined 1 month before, at initiation and 1 month after interferon-alpha therapy (3 x 10(6) units, three times a week). RESULTS There were no significant differences in the caffeine index (CYP 1A2) and in the 6-beta-hydroxycortisol/free cortisol urinary ratio (CYP 3A) before and after alpha interferon treatment CONCLUSION Chronic administration of interferon-alpha at therapeutic doses does not change in vivo cytochrome P-450 1A2 and 3A activities. These results support the suggestion that drugs metabolized by these isoenzymes may be used together with interferon-alpha in patients with chronic hepatitis C without significant risks of drug interactions.

Abstract
Amiodarone is an antiarrhythmic drug widely used to treat a variety of supraventricular and ventricular arrhythmias. However its drawback is a very slow elimination and very frequent adverse effects (thyroid, pulmonary, neurologic, ocular, dermatologic, hepatic disorders). We describe a patient who developed a pseudoalcoholic liver disease and a cirrhosis after use of Amiodarone for a long period of time.

Antiphospholipid antibodies (APAs) have been reported in various clinical conditions. However, the pathogenesis and clinical significance of these antibodies are still unclear. The objective of this study was to assess the prevalence of APAs in patients with chronic alcohol- or hepatitis C virus (HCV)-related liver disease and to evaluate their relation to the underlying liver disease. We prospectively studied 201 patients referred to an hepato-gastroenterology department, including 77 patients with a history of alcohol abuse (group I) and 124 with chronic HCV infection (group II), and 107 healthy subjects (control population). Liver biopsy was performed in all patients. In cirrhotic patients, the severity of the liver disease was assessed with the use of Child's classification, as modified by Pugh. Several biologic parameters, including lupus anticoagulant and anticardiolipin antibodies, were determined. Forty-eight percent of patients in group I and 33% of those in group II had APAs. Among cirrhotic patients, APAs were more frequent in patients with Child grade B or C than in those with grade A severity. In patients with chronic HCV-related liver disease, a correlation was found between APA levels and liver fibrosis (P = 0.009); no relation was found between APA levels and histologic liver disease activity (P = 0.25). In the control group, one subject was APA-positive. None had lupus anticoagulant. APAs seem to be frequently associated with chronic liver disease of various causes. These results suggest further investigations on the potential role of these antibodies in fibrosis or liver injury.

Abstract
BACKGROUND A high incidence of serum monoclonal immunoglobulins (mIgs) has been described after solid organ transplantation. For transplant recipients, the prevalence of posttransplant lymphoproliferative disorders (PTLDs) has been reported to be between 2% and 6%. The relationship between the finding of serum mIg in transplant recipients and the subsequent development of PTLDs is not clearly documented. METHODS We retrospectively analyzed all cases of mIg and PTLD that occurred in 86 liver transplant recipients who survived more than 3 months. Patients were characterized by protein electrophoresis, immunofixation electrophoresis, pre- and post-liver transplantation Epstein-Barr virus (EBV) serology, EBV presence in lymphoproliferative tissues by in situ hybridization, type of infection episodes, rejection episodes, and immunosuppressive treatment. RESULTS Thirty-eight patients (44%) had abnormal immunofixation electrophoresis with an electrophoretic Ig peak. Twelve patients had a polyclonal Ig peak, and 26 patients had mIgs (30%). These 26 patients were divided into two groups: 13 patients had a transient mIg peak with a mean delay for normalization of electrophoresis of 2 months, and 13 patients had a permanent mIg peak. No correlation could be demonstrated between the appearance of abnormal banding and indications for transplantation, age of patients, and acute rejection rate. There was a strong correlation between occurrence of viral infections and presence of permanent mIg. Three patients with permanent mIg (23%) developed PTLD and died. CONCLUSIONS We concluded that the prevalence of mIg after liver transplantation was 30%. Viral infections increase the risk of developing mIg. Persistence of mIg beyond 7 months may be regarded as prelymphomas necessitating a careful follow-up in these patients.
