Abstract: An ad hoc committee appointed by the Italian Association for the Study of the Liver (AISF) proposed these Practice Guidelines for the management of HCV carriers with persistently normal aminotransferase levels. Only stringent ALT determinations will make it possible to distinguish these subjects from those in temporary biochemical remission. The overall prevalence in Italy has been estimated between 1.5 and 10.6%. HCV RNA quantitation and genotype determination are not predictors of the presence and severity of liver damage nor correlate with the outcome of the disease, and should not be used in clinical practice for the management and surveillance of HCV carriers with normal ALT. Only a minority of HCV carriers with normal ALT levels show a normal morphological picture (true 'healthy carriers'). Disease activity is mild in most cases; fibrosis is generally mild and cirrhosis is very rare. Histological activity, as monitored by sequential liver biopsies, seems to have very slow evolution. HCV carriers should not undergo liver biopsy on a routine basis. Liver biopsy can be reasonably proposed only in selected cases. Until the results of studies with PEG interferon plus ribavirin are available, HCV carriers should not receive antiviral treatment outside controlled experimental studies.

Abstract: BACKGROUND AND AIMS: A deranged metabolic status and alcohol intake may trigger induction and progression of chronic hepatitis C virus (HCV) liver disease. The aim of this study was to evaluate whether dietary composition affects the severity of liver damage and response to therapy in patients with HCV-related chronic hepatitis. METHODS: We enrolled 1,084 patients with biopsy-proven HCV-related chronic hepatitis (432 treated with interferon plus ribavirin) and 2,326 healthy subjects in this prospective study conducted in a university hospital. Dietary habits were recorded in enrolled individuals, and their alcohol consumption was evaluated with a questionnaire (AUDIT). Body mass index, and plasma levels of blood glucose, nitrogen, creatinine, cholesterol, and triglycerides were also measured. All individuals underwent routine liver tests and HCV genotyping. RESULTS: At study onset, there were no differences in metabolic status or alcohol consumption between patients and controls. About 50% of each group was overweight, and about 60% consumed alcohol. Patients and controls had similar dietary habits. Intake of carbohydrates, lipids and polyunsaturated fatty acids, and alcohol consumption were independent factors of liver damage at histology (logistic regression analysis). Some dietary components (unsaturated fatty acids, iron, zinc, vitamin A, and niacin) and alcohol intake differed significantly (P < 0.05 and P 0.01, respectively; univariate analysis) between responders and nonresponders to interferon therapy. Genotype, age, body mass index, steatosis, and fibrosis were independent predictors of therapy outcome (P < 0.02; multivariate analysis). CONCLUSIONS: The severity of HCV-related chronic hepatitis depends on a variety of factors. Our results show that dietary composition is related to the extent of liver damage. Although traditional risk factors independently affected treatment response, some dietary components were associated with nonresponse to therapy in our patients. This suggests that HCV patients may benefit from instructions regarding their diet.

Abstract: BACKGROUND: We hypothesized that in patients with hepatitis C virus (HCV) genotype 2 or 3 in whom HCV RNA is not detectable after 4 weeks of therapy, 12 weeks of treatment is as effective as 24 weeks. METHODS: A total of 283 patients were randomly assigned to a standard 24-week regimen of peginterferon alfa-2b at a dose of 1.0 mug per kilogram weekly plus ribavirin at a dose of 1000 mg or 1200 mg daily, on the basis of body weight. Of these, 70 patients were assigned to the 24-week regimen (standard-duration group) and 213 patients to a variable regimen (variable-duration group) of 12 or 24 weeks, depending on whether tests for HCV RNA were negative or positive at week 4. The primary end point was HCV that was not detectable by polymerase-chain-reaction (PCR) assay 24 weeks after the completion of therapy. RESULTS: In the standard-duration group, 45 (64 percent) patients had HCV that was not detectable by PCR assay at week 4, as compared with 133 (62 percent) in the variable-duration group (difference [the rate in the standard-duration group minus that in the variable-duration group], 2 percent; 95 percent confidence interval, -11 to 15 percent). Fifty-three patients (76 percent) in the standard-duration group and 164 patients (77 percent) in the variable-duration group had a sustained virologic response (difference, -1 percent; 95 percent confidence interval, -13 to 10 percent). Fewer patients in the variable-duration group receiving the 12-week regimen had adverse events and withdrew than in the group receiving the 24-week regimen (P=0.045). The rate of relapse (defined as HCV not detectable at the end of treatment but detectable at the end of follow-up) was 3.6 percent in the standard-duration group and 8.9 percent in the variable-duration group (P=0.16). Overall, the rate of sustained virologic response was 80 percent among patients with HCV genotype 2 and 66 percent among those with genotype 3 (P<0.001). CONCLUSIONS: A shorter course of therapy over 12 weeks with peginterferon alfa-2b and ribavirin is as effective as a 24-week course for patients with HCV genotype 2 or 3 who have a response to treatment at 4 weeks.

Abstract: We determined whether triple therapy comprising amantadine (AMA), ribavirin (RBV) and either peginterferon (PEG-IFN) alpha-2a or conventional IFN alpha-2a would improve sustained virological response (SVR) rates over dual therapy with IFN alpha-2a and RBV in patients with chronic HCV infection. A total of 362 treatment-naïve patients were randomized to 48 weeks of treatment with: PEG-IFN alpha-2a 180 microg/week (group A) or IFN alpha-2a 3 MU tiw (groups B and C). All patients received RBV 1000 or 1200 mg/day and those in groups A and B received AMA 200 mg/day. SVR was defined as an undetectable HCV RNA after 24 weeks of untreated follow-up. At the end of therapy, 74.4% (95% CI 0.66-0.82) of patients in group A were HCV RNA-negative compared with 42.5% (95% CI 0.33-0.50) of those in group B (P = 0.0001) and 48.8% (95% CI 0.40-0.56) of those in group C. SVR was achieved in a significantly greater proportion of patients in group A compared with groups B and C: 65.3% (95% CI 0.53-0.56), 33.3% (95% CI 0.25-0.41) and 44.6% (95% CI 0.36-0.53; P = 0.0001) respectively. In patients with genotype 1, SVR rates were 55.2, 22.8 and 28.8% with the three regimens respectively. Factors independently associated with SVR were HCV genotype 2 or 3, therapy with PEG-IFN, female gender and age. In treatment-naive patients with chronic hepatitis C, triple therapy with PEG-IFN alpha-2a, RBV and AMA produces higher SVR than dual or triple therapy with conventional IFN alpha-2a.

Abstract: OBJECTIVE: To assess the incidence, cofactors, and excess risk of development of non-alcoholic fatty liver disease, including non-alcoholic steatohepatitis, attributable to tamoxifen in women. DESIGN: Prospective, randomised, double blind, placebo controlled trial. SETTING AND PARTICIPANTS: 5408 healthy women who had had hysterectomies, recruited into the Italian tamoxifen chemoprevention trial from 58 centres in Italy. INTERVENTION: Women were randomly assigned to receive tamoxifen (20 mg daily) or placebo for five years. MAIN OUTCOME MEASURE: Development of non-alcoholic fatty liver disease in all women with normal baseline liver function who showed at least two elevations of alanine aminotransferase (> or = 1.5 times upper limit of normal) over a six month period. RESULTS: During follow up, 64 women met the predefined criteria: 12 tested positive for hepatitis C virus, and the remaining 52 were suspected of having developed non-alcoholic fatty liver disease (34 tamoxifen, 18 placebo)--hazard ratio = 2.0 (95% confidence interval 1.1 to 3.5; P = 0.04). In all 52 women ultrasonography confirmed the presence of fatty liver. Other factors associated with the development of non-alcoholic fatty liver disease included overweight (2.4, 1.2 to 4.8), obesity (3.6, 1.7 to 7.6), hypercholesterolaemia (3.4, 1.4 to 7.8), and arterial hypertension (2.0, 1.0 to 3.8). Twenty women had liver biopsies: 15 were diagnosed as having mild to moderate steatohepatitis (12 tamoxifen, 3 placebo), and five had fatty liver alone (1 tamoxifen, 4 placebo). No clinical, biochemical, ultrasonic, or histological signs suggestive of progression to cirrhosis were observed after a median follow up of 8.7 years. CONCLUSIONS: Tamoxifen was associated with higher risk of development of non-alcoholic steatohepatitis only in overweight and obese women with features of metabolic syndrome, but the disease, in both the tamoxifen and the placebo group, after 10 years of follow up seems to be indolent.

Abstract: Expert consensus recommends liver biopsy before therapy for chronic hepatitis C. A cost effectiveness analysis suggested that the best strategy in the management of patients was to treat without biopsy. We compared therapy in patients who did, or did not undergo biopsy. Hepatitis C virus (HCV)-positive patients (78) who did not agree to (n = 57) or with contraindications to liver biopsy (n = 21) (group A) were matched for age, sex and genotype with those who consented (group B). Before therapy (interferon/ribavirin for 12 months), a clinical diagnosis of chronic hepatitis, on the basis of standard biochemical and ultrasonographic parameters. The two groups showed similar baseline characteristics. A noninvasive, diagnosis of chronic hepatitis was made in 75.6% of group A, and in 83.3% of group B (P = 0.26). Concordance between clinical and histological diagnosis in group B amounted to 91%. End-of-therapy virological response was 52.6% in group A, and 57.7% in group B (P = 0.63). Sustained virological response was 41.0% [95% confidence interval (CI) 30.1-51.9] and 43.6% (95% CI 32.6-54.6) in the two groups (P = 0.87). Predictors of sustained response were noninvasive diagnosis of chronic hepatitis (P = 0.006), lack of portal hypertension (P = 0.037), platelets >10(5)/mm3 (P = 0.007), prothrombin >70% (P = 0.02), and genotype 2 or 3 (P < 0.0001). At multivariate analysis, genotype (P < 0.0001) and platelets (P = 0.004) maintained their predictive power. In most patients with HCV infection, virological clearance after therapy can be achieved irrespective of whatever a liver biopsy might show.

Abstract: AIM: To investigate the prevalence of the clinical parameters of insulin resistance and diabetes in patients affected by chronic hepatitis C (CHC) or chronic hepatitis B (CHB). METHODS: We retrospectively evaluated 852 consecutive patients (726 CHC and 126 CHB) who had undergone liver biopsy. We recorded age, sex, ALT, type 2 diabetes and/or metabolic syndrome (MS), body mass index (BMI), and apparent disease duration (ADD). RESULTS: Age, ADD, BMI, prevalence of MS and diabetes in patients with mild/moderate liver fibrosis were significantly higher in CHC. However, the degree of steatosis and liver fibrosis evaluated in liver biopsies did not differ between CHC and CHB patients. At multivariate analysis, age, sex, BMI, ALT and diabetes were independent risk factors for liver fibrosis in CHC, whereas only age was related to liver fibrosis in CHB. We also evaluated the association between significant steatosis (>30%) and age, sex, BMI, diabetes, MS and liver fibrosis. Diabetes, BMI and liver fibrosis were associated with steatosis >30% in CHC, whereas only age and BMI were related to steatosis in CHB. CONCLUSION: These data may indicate that hepatitis C virus infection is a risk factor for insulin resistance.

Abstract: BACKGROUND/AIMS: Prevalence of HCV infection in non-Hodgkin's lymphoma is high. The impact of antiviral therapy on the natural history of this subgroup of lymphomas after a successful chemotherapy regimen is still an argument of debate. METHODS: We retrospectively examined 343 chemotherapy-treated patients referred to our centre for five consecutive years. Clinical and histological characteristics, disease free-survival (DFS) and overall-survival (OS) were compared in HCV-positive (69/343) and HCV-negative (274/343) patients. Twenty-five HCV-positive patients received antiviral treatment following chemotherapy discontinuation. Uni- and multivariate analyses were performed. RESULTS: 20% of lymphomas were HCV-positive. Indolent histology was prevalent in the HCV-positive group (p<0.05); no significant differences in OS or DFS were found between the two groups; in HCV-positive subjects, antiviral therapy, was associated with a longer DFS (p<0.05); none of the HCV-positive subjects who achieved a virological response experienced any lymphoma relapse; 29% of non responders did; at multivariate analysis, the independent factors related to a better clinical outcome were: indolent histology at the onset of lymphoma and antiviral therapy. CONCLUSIONS: Antiviral treatment in HCV-positive non-Hodgkin's lymphoma may be an important strategy to reinforce the results of a successful chemotherapy regimen; further studies are needed to validate this combined approach.

Abstract: BACKGROUND: While the likelihood of developing hepatocellular carcinoma (HCC) in patients coinfected with both HBV and HCV is increased, the role of previous exposure to HBV as a risk factor associated with tumor occurrence in subjects with HCV-related cirrhosis has not been fully investigated. AIM: To assess whether serum anti-HBc positivity, as a marker of previous HBV exposure, is associated with HCC development in HCV-related positive, hepatitis B surface antigen (HBsAg) negative patients with cirrhosis treated with alfa-interferon (IFN) monotherapy. PATIENTS AND: A database including 883 consecutive patients (557 men, mean age 54.7 yr) with histologically METHODS: proven cirrhosis treated with IFN between 1992 and 1997 was analyzed. All subjects have been surveilled every 6 months by ultrasound. Independent predictors of HCC were assessed by Cox multiple regression analysis. RESULTS: Mean follow-up was 96.1 months. Anti-HBc testing was available in 693 cases and, among them, 303 patients (43.7%) were anti-HBc seropositive. Anti-HBc positive patients were more often men (67.0%vs 58.7%, P= 0.03), had lower transaminase levels (3.3 +/- 2.0 vs 3.8 +/- 2.5 u.l.n., P= 0.004), and had higher rate of alcohol intake (38.3%vs 22.5%, P < 0.001) than anti-HBc negative patients. Overall, the incidence rates of HCC per 100 person-years were 1.84 (95% CI 1.34-2.47) in the anti-HBc positive patients and 1.86 (95% CI 1.41-2.42) in anti-HBc negative ones. By Cox multiple regression, there was no association of serum anti-HBc with HCC development (HR 1.03, 95% CI 0.69-1.52) or liver-related deaths incidence (HR 1.21; 95% CI 0.76-1.95). CONCLUSIONS: In comparison with anti-HBc negative subjects, serum anti-HBc positive patients with HCV-related/HBsAg negative cirrhosis treated with IFN monotherapy did not show a greater risk of HCC.

Abstract: BACKGROUND: Primary Hepatic (PHL) and Primary Splenic (PSL) non-Hodgkin's Lymphoma are rare entities. Small series of PHL and PSL have been reported, suggesting a non-fortuitous association with Hepatitis C Virus (HCV) infection. The prognosis is believed to be dismal, with early recurrence and short survival. PATIENTS: We retrospectively reviewed all PHL and PSL patients diagnosed at our institution between 1990 and 2005. RESULTS: Twenty-five adult patients were identified, six with PHL and 19 with PSL. Twenty-four patients had a B-cell lymphoma, defined as Diffuse Large B-cell lymphoma in 18. The prevalence of HCV infection was 68% among PSL and 66% among PHL. Combination chemotherapy was the mainstay of treatment for PHL and PSL; all but one patient with PSL underwent splenectomy before chemotherapy. Complete remission was achieved in all the cases after frontline therapy; only four patients relapsed but responded to additional chemotherapy courses. Most patients presented with aggressive histological subtypes; 92% were alive at a median follow up of 79 months. HCV infection did not appear to influence the results of therapy. CONCLUSION: Our study confirms the rarity of PHL and PSL, shows a high prevalence of HCV infection, and demonstrates that the outcome of patients with PHL and PSL may be favourable.

Abstract: Hepatitis C virus (HCV) infection is associated with a significant reduction of health related quality of life (QOL), the causes and mechanisms of which are still unknown. To explore whether treatment history could affect QOL, we examined patients with detectable HCV viraemia who had a different therapeutic background. Two hundred sixty-four consecutive subjects with chronic HCV infection and detectable viraemia were enrolled. Of these, 163 were untreated patients, 43 were relapsers, 58 were nonresponders (NR) to nonpegylated interferon (IFN) therapy. To assess QOL, three self-report instruments were employed: the Short Form-36 (SF-36), the Chronic Liver Disease Questionnaire (CLDQ-I) and the World Health Organization Quality of Life assessment (WHOQOL-BREF). Clinical and demographic data were collected, and the QOL scores of HCV-positive patients were compared with those of an Italian normative sample and healthy controls. Further antiviral treatment was offered to untreated and relapsed patients but not to NR. All patient groups displayed lower QOL scores compared with the normative sample and controls. NR displayed lower QOL scores in several areas compared with untreated patients and relapsers. In multivariate regression analyses, being NR and having a physical comorbidity were significantly associated with poorer QOL. Conclusions: Treatment history and expectations and physical comorbidity may affect QOL in HCV-positive patients. Untreated and relapsed patients have comparable levels of QOL and higher scores than NR.

Abstract: BACKGROUND: The response to antiviral therapy of chronic hepatitis C virus (HCV) infection is determined by virological, environmental and genetic factors. OBJECTIVE: The hypothesis was tested that the expression of specific genes and their haplotype frequencies can differentiate between non-responders (NRs) and sustained virological responders (SVRs) to antiviral treatment. METHODS: A methodological approach based on molecular marker discovery and validation was used to study the genes influencing the antiviral treatment in lymphoblastoid cell lines from 74 genotype 1b HCV patients (44 from Southern Italy and 30 from Northern Italy) treated with pegylated interferon (IFN) alpha and ribavirin. Furthermore, an association study was performed, testing three single nucleotide polymorphisms (SNPs) of suppressor of cytokine signalling 3 (SOCS3) in 162 NR and 184 SVR subjects (SOCS3 -8464 A/C (rs12952093), -4874 A/G (rs4969170) and 1383 A/G, (rs4969168)). RESULTS: SOCS3 basal expression levels were significantly increased in two independent sets of NR groups (p<0.05). A highly significant association was found between NRs and both the positively associated haplotype (OR = 2.01, 95% CI 1.45 to 2.79, p = 0.0002) and the negatively associated haplotype (OR = 0.56, 95% CI 0.42 to 0.76, p = 0.0014). In particular, the SOCS3 -4874 AA genotype was strongly associated with failure of antiviral therapy (OR = 4.00, 95% CI 2.09 to 7.66, p = 0.0003) and the AA genotype carriers had significantly higher SOCS3 mRNA and protein levels (p<0.05). CONCLUSIONS: Basal levels of SOCS3, an inhibitor of the IFN alpha-induced Janus kinase-signal transducer and activator of transcription pathways, and its genetic polymorphisms influence the outcome of antiviral treatment. SOCS3 thus represents a novel blood biomarker for the a priori prediction of treatment response.

Abstract: Liver steatosis, diabetes mellitus and hepatitis C virus (HCV) genotype have been implicated in liver fibrosis in HCV-related chronic active hepatitis (CAH). The aim of this study was to evaluate whether steatosis and diabetes were associated with more severe liver fibrosis in patients with genotype 1b HCV-related CAH. One-hundred and eighty patients (98 men, 82 women; age range 17-68 years; median 51) infected with genotype 1b HCV underwent ultrasound examination and liver biopsy because of elevated levels of serum alanine transaminase. Based on liver histology, patients were divided into three steatosis classes: 1 (involving <33% of hepatocytes), 2 (34-66%) and 3 (>66%). Fibrosis was graded with the Ishak score (range: 0-6). Virological and epidemiologic characteristics, biochemical data, body mass index, and apparent duration of disease were recorded. Diabetes was identified according to American Diabetes Association criteria. The median fibrosis grade was 2 (23 patients had liver cirrhosis) in the three steatosis classes, with no significant differences between classes. At multivariate analysis, fibrosis was significantly related to age, alanine transaminase, diabetes, hepatitis B core antibody, steatohepatitis and grading. At binary logistic regression analysis, only diabetes and fibrosis stage were significantly associated with steatohepatitis. Steatosis was not an independent risk factor for liver disease severity in our CAH/genotype 1b HCV-infected patients. Steatohepatitis was associated as well as diabetes and affected the severity of liver fibrosis.

Abstract: The response to antiviral therapy is lower in hepatitis C virus (HCV) patients with genotype 1 than in those with genotype 2. Overexpression of the suppressor of cytokine signaling 3 (SOCS3) gene in liver tissue is associated with a poorer treatment outcome in patients with chronic hepatitis C viral genotype 1. Also, insulin resistance has been implicated in nonresponse to an anti-HCV treatment. To understand why HCV genotype 1 patients respond differently, we investigated SOCS3 gene expression, metabolic syndrome (MS), and the response to therapy in a cohort of patients with HCV-related hepatitis. A total of 198 patients (108 with genotype 1 and 90 with genotype 2) treated with pegylated interferon plus ribavirin were consecutively enrolled in the study. We measured SOCS3 expression in Epstein-Barr virus-transformed lymphoblastoid cell lines derived from peripheral lymphocytes of a subset of 130 patients. MS was more frequent in genotype 1 patients than in genotype 2 patients (P < 0.01). Nonresponders (P < 0.01), MS (P < 0.001), and genotype 1 (P < 0.001) were significantly related to SOCS3 overexpression. However, SOCS3 levels were higher in nonresponders also, regardless of the genotype (P < 0.01). In a univariate analysis, the genotype (P < 0.001), age (P < 0.001), SOCS3 (P < 0.001), and MS (P < 0.001) were significantly related to the response to therapy. However, in a multivariate analysis, SOCS3 was the only independent predictor of the response (odds ratio = 6.7; P < 0.005). CONCLUSION: We speculate that SOCS3 expression per se may influence the response to antiviral therapy and that the genotype 1b virus might induce its up-regulation. This may account for the different responses to therapy between genotype 1-infected and genotype 2-infected patients.

Abstract: The effect of achieving a sustained virological response (SVR) following interferon-alpha (IFNalpha) treatment on the clinical outcomes of patients with HCV-related cirrhosis is unknown. In an attempt to assess the risk of liver-related complications, HCC and liver-related mortality in patients with cirrhosis according to the response to IFNalpha treatment, a retrospective database was developed including all consecutive patients with HCV-related, histologically proven cirrhosis treated with IFNalpha monotherapy between January 1992 and December 1997. SVR was an undetectable serum HCV-RNA by PCR 24 weeks after IFNalpha discontinuation. HCC was assessed by ultrasound every 6 months. Independent predictors of all outcomes were assessed by Cox regression analysis. Of 920 patients, 124 (13.5%) were classified as achieving a SVR. During a mean follow-up of 96.1 months (range: 6-167) the incidence rates per 100 person-years of liver-related complications, HCC and liver-related death were 0, 0.66, and 0.19 among SVR and 1.88, 2.10, and 1.44 among non-SVR (P<0.001 by log-rank test). Multivariate analyses found that non-SVR was associated with a higher risk of liver-related complications (hazard ratio, HR, not applicable), HCC (HR 2.59; 95% CI 1.13-5.97) and liver-related mortality (HR 6.97; 95% CI 1.71-28.42) as compared to SVR. CONCLUSION: Thus, in patients with HCV-related, histologically proven cirrhosis, achievement of a SVR after IFNalpha therapy was associated with a reduction of liver-related mortality lowering both the risk of complications and HCC development. Irrespective of SVR achievement, all patients should continue surveillance because the risk of occurrence of HCC was not entirely avoided.

Abstract: BACKGROUND/AIMS: In this study, we determined the genotypic and allelic frequencies of the Interleukin (IL)-10(-1082G/A) IL-10(-592A/C), and IL-10(-819C/T) polymorphisms, and their association with the risk to develop B cell Non Hodgkin Lymphoma (NHL) in hepatitis virus C (HCV) carriers. RESULTS: Genetic polymorphisms in the IL-10 gene promoter were studied in 250 consecutive patients with B-cell NHL with no clinical and/or laboratory findings of cryoglobulinemia, 142 NHL/HCV- and 108 NHL/HCV+ with chronic hepatitis (CH), 120 consecutive subjects with HCV-related CH, and 110 age, sex-matched healthy blood donors. The frequency of the IL-10(-1082GG) genotype vs remaining genotypes (IL-10(-1082GA/AA)) was higher in NHL/HCV+ patients than HCV-related CH patients (P=0.0002, OR=2.89, CI: 1.62-5.15) and in NHL/HCV+ than NHL/HCV- patients (P=0.0001, OR=2.99, CI: 1.72-5.19). Moreover, the IL-10(-1082GG) genotype was more prevalent in indolent NHL/HCV+ cases than aggressive NHL/HCV+ (P=0.0004, OR=4.97, CI: 2.10-11.79). Finally, we confirmed that IL-10(-1082GG) genotype is associated with higher IL-10 production compared to AA homozygous (P=0.037). CONCLUSIONS: The high IL-10 production, due to IL-10(-1082GG) genotype, influences the clinical expression of the HCV infection by increasing susceptibility to develop NHL and might contribute to the indolent form of the disease.

Abstract: Some chronic hepatitis C (CHC) patients exhibit persistently normal alanine aminotransferase (ALT) levels (PNAL). Patients with PNAL experience significantly milder disease. In order to understand the differences between CHC patients with elevated ALT levels compared with those with PNAL better, we compared epidemiological, immunological and histological findings, in particular, the value of proliferating hepatocyte activity (PCNA) between the two groups of patients. We studied 40 chronic hepatitis C virus (HCV) carriers with increased ALT who underwent liver biopsy for histological diagnosis and determination of clinical prognosis, and 24 PNAL patients under follow-up for 10 years. Immunological response to different HCV genomic epitopes was tested in both the control group and in PNAL subjects. PCNA values from liver specimens of all patients as well as liver biopsies of PNAL patients at time points 0 and 5 years were calculated according to Hall et al.Age, sex and body mass index (BMI) were not significantly different between the two groups. The median liver histology stage was significantly higher in HCV carriers vs the PNAL group (2.5, range = 2-6 vs 1.5, range = 1-2; P < 0.01). Among PNAL patients, histological stage was not statistically different at the three time points considered. Interferon (IFN)-gamma production was comparable in the two groups. PCNA was significantly higher in the group with elevated ALT levels vs the PNAL group (8%, range = 4-15%vs 5% range = 3-8%; P < 0.05) and no statistically significant differences were found in PNAL patients at time points 0, 5 and 10 years. This study confirms that progression to cirrhosis is slow or absent in PNAL patients after 10 years of follow-up. Accordingly, the hepatic proliferative activity index is low and seems to be stable over time.

Abstract: BACKGROUND: The Chronic Liver Disease Questionnaire is a specific health-related quality of life assessment designed for patients with liver diseases. AIM: The aim of this paper is to report on the validity, reliability and sensitivity to change of the Italian version (Chronic Liver Disease Questionnaire-I) in subjects with HCV infection. SUBJECTS: The Chronic Liver Disease Questionnaire-I was administered to 350 subjects with HCV infection together with the World Health Organization Quality of Life Assessment, abbreviated version, a generic quality of life assessment. METHODS: The instrument was translated from English, backtranslated and reviewed in focus groups in the framework of a large multicentre study. Exploratory factor analysis identified five factors accounting for 65% of the variance of Chronic Liver Disease Questionnaire-I items and only partially overlapping with those found in the original version. RESULTS: The Chronic Liver Disease Questionnaire-I proved to discriminate between subjects with and without comorbid diseases at baseline (t-test = 3.59, p < 0.001). Test-retest reliability was moderate (ICC = 0.60). The Chronic Liver Disease Questionnaire-I was sensitive to change in patients who deteriorated after one month of treatment. Change in the overall Chronic Liver Disease Questionnaire-I score in deteriorated patients was correlated with changes in World Health Organization Quality of Life Assessment, abbreviated version scores in the physical, psychological and environment, but not in the social area. CONCLUSIONS: The Italian version of Chronic Liver Disease Questionnaire is a valid and reliable instrument to be used in cross-sectional and longitudinal studies.

Abstract: Hepatitis C virus (HCV) infection is an emerging global epidemic, and no effective cure is yet available. Interferon-alpha (INFalpha) and pegylated INFs, in combination or otherwise with ribavirin, have proven to be effective in no more than 50% of chronically infected patients. New and better therapeutic strategies are therefore needed. HCV nonstructural protein 3 (NS3) RNA helicase (h) is a promising target for developing new therapeutics. QU663 was discovered as a potent new selective inhibitor of the helicase reaction of HCV NS3 (K(i) = 0.75 microM), competing with the nucleic acid substrate without affecting ATPase function, even at high concentrations. QU663 is one of a new generation of small-molecule nucleotide-mimicking inhibitors which are potential anti-HCV agents. A thorough molecular modeling study was carried out to explain the molecular basis of NS3h inhibition by QU663. The resulting three-dimensional interaction model is discussed.

Abstract: BACKGROUND AND OBJECTIVES: Chemotherapy can cause hepatitis flare-up through viral reactivation in patients who have had contact with hepatitis viruses. Few data are available on the genotype of the reactivated viruses. DESIGN AND METHODS: In 40 consecutive adult patients with indolent non-Hodgkin's lymphoma (NHL) receiving fludarabine-based front-line chemotherapy, we performed a prospective study on viral hepatitis reactivation and analyzed the genotype of the reactivated viruses. Before chemotherapy, 4 patients were healthy carriers of hepatitis B surface antigen (HBsAg), 2 had HB core antigen antibodies (anti-HBc), 6 anti-HBs and 6 anti-HCV; 22 were seronegative. RESULTS: Hepatitis flare-up occurred in the 4 HBsAg-positive patients and in 1 anti-HBc-positive patient at a median of 1 month (range 1-4) after chemotherapy, when the CD4/CD8 ratio was still inverted. HBV reactivation was documented in all 5 instances (HBV-DNA 2-8 x 10(6) copies/mL). Two of the 5 patients responded to lamivudine, whereas 1 died of acute liver failure and 2 had persistent severe hepatitis. HBV genome sequencing at hepatitis flare-up showed that deviation from the closest related published sequences was 1.0% and 1.1% in the 2 lamivudine-responsive patients, and 1.5%, 1.8% and 1.7% in the 3 lamivudine-resistant patients. The polymerase open reading frame (ORF) and the HBs ORF of lamivudine-resistant strains contained several novel amino acid substitutions. INTERPRETATION AND CONCLUSIONS: These results suggest that fludarabine treatment of HBV-infected patients is frequently associated with acute hepatitis due to viral reactivation, and that lamivudine may be less effective in this situation than in other settings of immunocompromised hosts because of the emergence of resistant mutant strains.

Abstract: OBJECTIVE: A high prevalence of cryoglobulins has been reported in patients with hepatitis C virus (HCV)-related liver disease. The aim of this study was to evaluate the prevalence and the incidence of cryoglobulins and their association with clinical symptoms in chronic hepatitis and cirrhosis patients. METHODS: The prevalence of cryoglobulins and cryoglobulinemic syndrome was investigated at enrollment in 237 patients (213 with chronic hepatitis and 24 with cirrhosis). A 7-yr follow-up was conducted evaluating the occurrence of cryoglobulins and/or cryoglobulinemic syndrome every 6 months. Rheumatoid factor was also tested in all patients. RESULTS: Prevalence of rheumatoid factor, cryoglobulins, and cryoglobulinemic syndrome in chronic hepatitis patients were 2%, 0.8%, and 0%, respectively. In cirrhosis patients the prevalence was 4%, 8%, and 0%, respectively. No statistically significant differences were found between the two groups. During the follow-up only one patient for each group abruptly developed cryoglobulinemic syndrome, and none of the patients who showed signs of cryoglobulinemia developed the syndrome or showed signs of evolution of the disease. CONCLUSIONS: Our data demonstrate that the presence of cryoglobulins and/or cryoglobulinemic syndrome in HCV-related liver disease is unusual, as is the occurrence of cryoglobulinemia over time in these patients. This leads us to think that HCV-related cryoglobulinemic syndrome and HCV-related liver disease are independent diseases. This supports new and indirect evidence for an independent and direct role of HCV in liver and blood disorders.

Abstract: Patients with persistently normal ALT affected with HCV-related chronic hepatitis exist. The natural history of liver disease in these patients was demonstrated to be very slow and progression to cirrhosis likely absent. The case we report describes the occurrence of hepatocellular carcinoma (HCC) in a patient with persistently normal ALT affected with mild chronic hepatitis. This observation suggests that asymptomatic carriers of HCV may develop HCC that is not related to underlying liver cirrhosis.

Abstract: BACKGROUND AND OBJECTIVES: During the last decade an epidemiological association between hepatitis C virus (HCV) and B-cell lymphoproliferative disorders (B-LPD) has been reported; the same association has not been observed for Hodgkin's disease (HD). Hepatitis G virus (HGV) shares genetic and biological features with HCV, thus it might also be involved in lymphomagenesis. DESIGN AND METHODS: The aim of this study was to compare the prevalence of HCV and HGV infection in patients at diagnosis of B-LPD or HD. RESULTS: We tested 227 consecutive untransfused patients (127 with B-LPD and 100 with HD) and 110 healthy controls. The prevalence of HCV infection was significantly higher in B-LPD patients than in controls (17.3% vs. 1.8%, p<0.002 ), whereas it was the same in HD patients as in controls. In contrast, the prevalence of HGV was significantly higher in patients, both those with B-LPD (7.8% vs. 0.9%, p<0.03) and those with HD (13% vs. 0.9%, p<0.002), than in controls. Among the various B-LPD tested, HGV infection was more frequent in B-NHL (11.5%). INTERPRETATION AND CONCLUSIONS: Our data support the hypothesis that HGV infection may play a role in lymphomagenesis and that this role is different and separate from that of HCV.

Abstract: BACKGROUND AND OBJECTIVES: The optimal method for liver biopsy in patients with simultaneous bone marrow and liver impairment has not yet been established. New approaches (e.g. imaging-guided methods) for this procedure are needed. In spite of coagulopathy, immunosuppression, anemia or ascites, we histologically characterized liver damage in a series of bone marrow transplanted patients using color-Doppler ultrasonography, which permits very keen visualization (and assessment) of hepatic parenchyma and vessels, and a fine needle for percutaneous biopsy. DESIGN AND METHODS: We performed percutaneous liver biopsy using a Menghini-type automatic very fine cutting needle (1.2 mm, 18G) under color ultrasound guidance in 16 bone marrow transplanted adult patients consecutively seen in our units from 1998 to 2001. The patients had clinically defined diffuse serious liver damage; liver biopsy was performed between 3 and 10 months after allogeneic (n= 11) or autologous (n= 5) transplantation. RESULTS: Fifteen patients tolerated the procedure well and had no discomfort, while one patient developed intrahepatic hemorrhage. All liver biopsies were suitable for histologic examination and informative, revealing the specific etiology of liver damage: graft-versus-host disease in six patients, drug toxicity in five, hepatitis C virus acute reactivation in two, and in one each vanishing bile duct syndrome, nodular regenerative hyperplasia and hemochromatosis. Biopsy detected potentially injurious concomitant factors, e.g., occult intrahepatic hepatitis B virus infection and reactivation. Histology radically changed the presumptive clinical diagnosis in 10 of the 16 patients and led to successful treatment changes in six. INTERPRETATION AND CONCLUSIONS: Percutaneous biopsy with a small cutting needle under color ultrasound guidance carries a low risk of complications and provides reliable information regarding liver histology in critically ill patients, in the early stage after bone marrow transplantation. We suggest including this imaging-guided mini-invasive procedure to the standard work-up of post-transplant liver damage.

Abstract: BACKGROUND & AIMS: Some patients with serum hepatitis C virus (HCV) have persistently normal aminotransferase (ALT) levels and are affected by cirrhosis. This study prospectively evaluated progression of the disease in a group of anti-HCV-positive patients with persistently normal ALT levels. METHODS: Thirty-seven subjects were studied. Each subject underwent liver biopsy at baseline and after 5 years of follow-up. At baseline, serum samples were tested for genotypes and HCV RNA load. ALT levels and serum HCV RNA were tested every other month and every 6 months, respectively. Patients with increased ALT were discharged from the study and treated with IFN. Five years after the end of IFN therapy, a liver biopsy was performed. RESULTS: Liver biopsy at baseline showed chronic hepatitis in 34 patients and normal histology in 3 patients, 2 of whom were negative for HCV RNA and 1 positive. HCV genotypes were distributed as follows: 2a, 56%; 1b, 41%; and 1a, 3%. At the end of 7-year follow-up, 73% of the patients still had normal ALT values. Liver histology after 5 years was comparable to that observed at entry to study. CONCLUSIONS: Most patients with persistently normal ALT serum levels have very mild chronic hepatitis. However, healthy anti-HCV-positive subjects exist. In patients with HCV-related chronic hepatitis associated with persistently normal ALT levels, the grade of disease activity does not increase over years and progression to cirrhosis is slow or absent.
