Abstract: Infection with the hepatitis C virus (HCV) represents an important public health problem and is a leading cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma. Chronic hepatitis C is a heterogeneous disease. Many patients have mild disease at presentation but not all of them will develop advanced liver disease. However, the identification of these patients with mild hepatitis C who will show progressive disease is difficult and is based on histological criteria and the assessment of co-factors (age, alcohol intake, steatosis). In addition, serum transaminases that are persistently normal on several occasions during 18 months may point to a more benign course. Patients with mild hepatitis C should not be excluded "a priori" from the possibility of being treated, as treatment with pegylated interferon and ribavirin is safe and effective in this group. Overall, the decision to initiate therapy should be individualized and based on the severity of the disease by liver biopsy, the potential of serious side effects, the probability of response and the motivation of the patient.

Abstract: Results of treatment for chronic hepatitis C have improved substantially during the last decade. Combination treatment with interferon alpha 3 MU tiw and ribavirin 1000-1200 mg daily during 24 to 48 weeks leads to sustained virologic response (SVR) in approximately 40% of patients, two to three times more than interferon alpha monotherapy. It was considered standard therapy at the EASL Consensus Conference of February 1999. Recently, results have been published on treatment with pegylated interferons alone and in combination with ribavirin. Pegylated interferon treatment leads to almost doubling of SVR rate as compared with standard interferon monotherapy. Combination of pegylated interferon alpha with ribavirin is most promising, leading to a SVR rate of 54 to 56%. It is to be expected that this treatment will become the new standard. Selected patients with geno-type 2 or 3 have now a SVR rate of almost 80%. Response to treatment also leads to significant improvement of quality of life and survival, probably by reducing the risk of developing hepatocellular carcinoma. Recent data suggest that early interferon alpha treatment of patients with acute hepatitis C largely prevents the development of chronicity.

Abstract: The standard treatment for patients with chronic hepatitis C is a 6-12-month combination therapy with interferon alpha and ribavirin. Induction treatment could result in a faster early decline of the hepatitis C virus (HCV) load and a better response rate. Naive chronically infected HCV patients (n = 454) were randomized into two arms to receive either induction treatment with interferon alpha 2b 5 million units (MU) subcutaneously (s.c.) daily during a period of 8 weeks (arm A); or treatment with interferon alpha 2b 5 MU s.c. three times a week (TIW) for a period of 8 weeks (arm B). After week 8, interferon treatment in both arms was 3 MU s.c. TIW for a total period of 12 months. In both arms, ribavirin (1000-1200 mg orally per day) was added at week 4. Induction treatment resulted in a higher virological response at week 8 of treatment (66%vs 47%; P < 0.01). However, response at the end of treatment and at 6 months follow-up was not different (53%vs 50%, 41%vs 33%). The occurrence of adverse events and the drop-out rate were similar in both arms. Although an early virological response is observed more frequently in the induction treatment, end of treatment response and sustained responses did not differ.

Abstract: BACKGROUND AND STUDY AIMS: The combination of Pegylated (PEG)interferon alpha-2b and ribavirin is considered to be the standard treatment for naïve chronic hepatitis C patients. Study aims are to evaluate the differences between standard interferon and PEG-interferon by conducting a multi-centre, controlled randomized trial comparing 3 groups. Group A : daily interferon alfa-2b at a dose of 4 MIU + ribavirin, Group B : PEG-interferon alfa-2b at a dose of 100 mcg/week + ribavirin; Group C: interferon alfa-2b at a dose of 3 MIU TIW + ribavirin PATIENTS AND METHODS: Multicentrer, open label study including naïve chronic Hepatitis C Virus patients randomised in three groups with a ratio of 2:2:1. Group A: daily interferon alpha-2b (4 MIU s.c. for patients > 65 kg or 0.06 MIU/kg < 65 kg) and ribavirin, group B: PEG-interferon alpha-2b (100 microg s.c. weekly for patients > 65 kg or 1.5 microg/kg weekly for patients < 65 kg) and ribavirin and group C (reference arm) : interferon alpha-2b (3MIU s.c. TWI) and ribavirin. The duration of the treatment was 48 weeks for all 3 groups, with a 6 month follow-up period. 336 patients were enrolled in the study and included in the intention-to-treat analysis; 78 never started treatment (35 in group A, 28 in group B and 15 in group C): 101 in group A, 98 in group B and 59 in group C. RESULTS: Demographic data, PCR results and reasons for early withdrawal have been statistically analysed. At baseline, the 3 groups did not show any statistical difference regarding age, gender, race, genotypes and METAVIR score. At week 24 on treatment, HCV ribonucleic acid RNA was undetectable in 87% in group A, in 79% in group B and in 69% in group C. At the end of treatment, 73% 74% and 58% respectively, had a negative PCR result. At week 24 of follow-up, these results were 71%, 64% and 48%, respectively. When comparing the efficacy of the daily interferon (+ ribavirin) and the PEG-interferon (+ ribavirin) regimen, no statistical difference was found (p = 0.32). In group A, 38% of drop-outs were due to adverse events compared to 37% in group B and 58% in group C. No statistical differences were observed regarding safety. CONCLUSION: Daily weight based interferon alpha-2b dosing and PEG interferon alpha-2b weighed based dosing once weekly both in combination with Ribavirin offer the same efficacy and safety rates.

Abstract: Prior to the introduction of virally inactivated clotting factor concentrates, the majority of patients with haemophilia became infected with the hepatitis C virus. Although transjugular liver biopsy can be safely performed in these patients, the procedure is associated with a significant financial burden mainly related to replacement therapy with clotting factor. The purpose of this study was to evaluate the feasibility and safety of transjugular liver biopsy in patients with haemophilia substituted with clotting factor concentrates for major surgical procedures. Over the last 5 years, transjugular liver biopsy was performed in nine patients with haemophilia within 1-10 days after orthopaedic (7), thoracic (1) or abdominal surgery (1). All patients had abnormal liver function tests and persistent hepatitis C viraemia. At the time of the biopsy, patients received recombinant factor VIII delivered by dose-adjusted continuous infusion through a central catheter inserted preoperatively in the left internal jugular (n = 8) or in an ante-cubital vein (n = 1). Before the biopsy, basal FVIII levels were raised to 80-100% by a bolus infusion and maintained above 80% for 24 h. The biopsy was informative in all cases. Only one patient developed an episode of supraventricular dysrhythmia. No bleeding or infectious complications were observed. When compared with elective liver biopsy performed outside the postsurgical period, the cost-savings per biopsy were 19 875 +/- 2660 euro. This study shows that intensive replacement therapy required by surgical procedures provides a safe and cost-effective opportunity for transjugular liver biopsy in patients with haemophilia and active hepatitis C.

Abstract: AIMS: To estimate viral seroprevalences for HCV, HBV and HIV among belgian intravenous (IVDU) and non intravenous (non-IVDU) drug users; to assess risk factors for HCV infection in IVDU; to assess feasibility of chronic hepatitis C follow-up in this population. DESIGN: Cross-sectional study. Demographic and behavioural characteristics were obtained by a standardized questionnaire. Serum samples were tested for HCV, HBV and HIV. SUBJECTS AND SETTING: 329 patients (244 IVDU and 85 non-IVDU) attending ten general practitioners in 1995. RESULTS: HCV seroprevalence was 78.3%; it was 35.7% for HBV and 0.9% for HIV in IVDU, vs 2.4%, 8.3% and 0%, respectively, in non-IVDU. In logistic regression analysis, independent risk factors for HCV infection were: 1/sharing of syringes and/or of "cottons" used as filters (adjusted prevalence odds ratio [POR] = 31.7; 95% confidence interval [CI] = 9.8-102.5), 2/duration of injecting upper than one month (adjusted POR = 8.6; CI = 3.0-24.7) and 3/age (adjusted POR = 1.2 by year of difference; CI = 1.0-1.3). A biochemical follow-up was obtained in 70% of HCV seropositive users; 79.5% of them had chronic hepatitis C (mean value of ALT = 3.5 times upper normal value, range 1.1-23.0). Among these, 24.7% went through liver biopsy during the three years follow-up period of the study. CONCLUSIONS: HCV seroprevalence is very high among belgian IVDU. Prevention strategies have to focus on neophytes injectors. They must be urgently revisited for what concern needles/syringes exchange programs: "cottons" must be included. Follow-up and treatment of chronic hepatitis C seem to be poorly effective among drug users.

Abstract: BACKGROUND & AIMS: Drug-induced immunoallergic hepatitis typically affects a minority of patients exposed to a particular drug. Its rarity is believed to be due to metabolic or immunologic idiosyncrasy. The presence of an immunologic idiosyncrasy might imply an HLA association. Previous studies reporting an HLA association of drug-induced hepatitis included only small numbers of patients and used serological HLA typing. METHODS: We studied 35 patients with biopsy-documented amoxicillin-clavulanate-induced hepatitis. HLA-A and -B were typed using alloantisera and compared with those of 300 controls (volunteer bone marrow donors). HLA-DRB and -DWB were typed by polymerase chain reaction-line probe assay, with 60 volunteer bone marrow donors serving as controls. RESULTS: The study group was characterized by a higher frequency of DRB1*1501-DRB5*0101-DQB1*0602 haplotype (57.1% vs. 11.7% in controls, P < 0.000005; after correction for the large number of comparisons, P < 0.0002). Patients with DRB1*1501-DRB5*0101-DQB1*0602 haplotype were more likely than patients without it to have a cholestatic (70% vs. 60%) or mixed (30% vs. 13%) than a hepatocellular pattern of hepatitis (0% vs. 27%) (P < 0.05). CONCLUSIONS: Amoxicillin-clavulanate-induced hepatitis is associated with the DRB1*1501-DRB5*0101-DQB1*0602 haplotype. The data support the view that an immunologic idiosyncrasy, mediated through HLA class II antigens, plays a role in the pathogenesis of drug-induced immunoallergic hepatitis. HLA association has a limited impact on the expression of hepatitis.

Abstract: BACKGROUND: Transjugular intrahepatic portosystemic shunting (TIPS) has become an effective treatment for the complications of portal hypertension. We assessed the feasibility and outcome of TIPS in liver transplant recipients. METHODS: During the period from December 1992 to January 1998, eight adults presenting recurrent hepatitis C virus (five patients) and hepatitis B virus (one patient) infection, veno-occlusive disease (one patient), and secondary biliary cirrhosis (one patient) had TIPS because of refractory ascites (five patients), bleeding esophageal varices (one patient), refractory hepatic hydrothorax (one patient), retransplantation (two patients), and redo-biliary surgery (one patient). RESULTS: In two patients, the procedure was difficult due to cavo-caval implantation. Ascites, hydrothorax, and variceal bleeding were controlled in all patients. Moderate to severe encephalopathy developed in four patients; two patients had worsening of their existing encephalopathy. Three of five patients treated with cyclosporine needed a drastic dose reduction due to the development of severe side effects. No long-term survivor developed shunt stenosis or occlusion. Two patients did moderately well at 6 and 14 months, respectively; the former died due to chronic rejection while waiting for a retransplantation. Three did well at 14, 36, and 28 months, respectively; the latter patient died of liver failure 32 months after TIPS. One jaundiced patient died after 1.5 months due to necrotic pancreatitis. Two patients died after 4 and 8.5 months, respectively, due to liver failure; the latter was doing well until 7 months after TIPS. CONCLUSIONS: TIPS is feasible in transplant recipients in cases of decompensated allograft cirrhosis, of allograft veno-occlusive disease or when retransplantation or redo-biliary surgery are scheduled in the presence of portal hypertension. At transplantation, the surgeon should keep in mind the eventuality of a later TIPS procedure. Close immunosuppression monitoring is warranted because modified metabolization of cyclosporine (and probably tacrolimus) may cause serious side effects.
