Abstract
BACKGROUND Sustained virological response (SVR12) rates at 12 weeks after treatment for HCV-infected patients with decompensated cirrhosis are used when referring to those with moderate functional impairment, while few data are available for those with more severe impairment. The use of the cirrhosis staging system proposed by D'Amico might provide new insights on timing for antiviral therapy. METHODS We investigated efficacy (SVR12), safety, and post-treatment variations in clinical and laboratory parameters in 2612 patients with advanced fibrosis (n=575) or cirrhosis (n=2037). Cirrhosis was in the compensated phase (without/with varices) or had previously been in the decompensated stage. Different direct-acting antiviral (DAA) regimens were administered in accordance with scientific guidelines. RESULTS The SVR12 rate was 97.6% in patients with advanced fibrosis. For patients with cirrhosis, the rate was 96.5% in stage 1, 95.1% in stage 2, 100% in stage 3, 95.7% in stage 4, and 93.6% in stage 5. These rates were independent of gender, age, HCV genotype, and treatment schedule. Positive changes in biochemical parameters and CPT classes following therapy were evident in compensated and previously decompensated patients. CONCLUSION Our findings support the use of DAAs in patients with advanced cirrhosis (stages 3-5) who are at greatest risk and have the most to gain from therapy.

Abstract
This retrospective multicentre study aims to evaluate the clinical and epidemiological features of HCV infection in a cohort of immigrants in Italy. Tests were carried out on 194 HCV positive subjects, who represented 5.7% of the participants at baseline screening: the virological (viral load, genotype) and biochemical appearance of their infection was determined, and the disease was staged by histological examination in the patients who had indicated their willingness. Standard therapy (peg-interferon + ribavirin) was implemented in patients who agreed to undergo treatment. The majority of immigrants were of East-European origin (48.4%), females were globally slightly predominant and the average age was 41.4 years. Of the 194 patients, 119 (63.1%) proved to be viraemic: genotype 1 was the most frequent, followed by genotype 4, the latter mainly in African patients. The histological staging of liver disease conducted in 25 patients showed mild hepatitis in 13 subjects, moderate/severe hepatitis in eight subjects and cirrhosis in four. Although 45 out of 119 patients (37.8%) with determinable HCV RNA agreed to undergo treatment, 11 of them independently stopped taking medication before the course of therapy was completed, without any significant side effects. At the sixth month of follow-up, the overall sustained virological response (SVR) was shown by 22/45 patients (48.8%). In our study, migrant populations had higher rates of HCV-related chronic hepatitis than the indigenous population; in some cases the infections were contracted in the country of origin, but in others the infection took place in Italy. The most commonly represented genotype, besides 1, was 4, especially among Africans. The therapeutic management of immigrants proved to be very difficult, mostly but not exclusively because of social factors.

Abstract
BACKGROUND & AIMS Different prevalence of favourable IL28BCC genotype have been reported in studies performed in different countries around the world. Data on distribution of IL28B genotypes in healthy Italian subjects are lacking. METHODS Studies on prospectively collected untreated chronic HCV-infected Italian patients led to conflicting results. To investigate the prevalence of IL28B genotypes in untreated HCV-infected patients and in subjects able to clear HCV, and to compare them to the prevalence registered in healthy Italian controls. To evaluate IL28B prevalence across different HCV genotypes. RESULTS IL28BCC was observed in 30.9% of chronic HCV patients, in 71.0% of subjects able to clear HCV infection and in 41.6% of the Italian controls. The frequency of IL28BCC was higher in HCV genotype 2 and 3 than in 1 (38.3 vs. 28.2) (P = 0.02). Levels of ALT higher in IL28BCC than in non-CC were observed regardless of HCV genotypes (P = 0.0014). CONCLUSIONS IL28BCC frequencies progressively decline from subjects with spontaneous HCV clearance to normal non-infected subjects and to chronically infected. This study suggests that patients with IL28BCC, if genotype 1, are able to clear HCV more often than if genotype 2 and 3 infected, and that CC genotype is associated with higher grade of necro-inflammation.

Abstract
BACKGROUND Triple therapy including Telaprevir or Boceprevir still represents in many European countries the standard of care for patients with Hepatitis C Virus genotype 1 infection. The number of patients who received this treatment resulted generally lower than expected. We investigated, among naïve patients, number and characteristics of treatment candidates who were started on triple or dual therapy in comparison to those who were deferred. PATIENTS AND METHODS 621 naïve treatment candidates were prospectively evaluated at each center. Factors associated with decision to defer or treat with dual or triple therapy were investigated by univariate and multivariate analyses. Rates of Sustained Virological Response and safety profile were analysed. RESULTS Of candidates to treatment, 33% did not received it. It was mostly due to high risk of Interferon-induced decompensation. Of 397 patients who were started on treatment, 266 (67%) received triple, 131 dual. Among patient receiving treatment, unfavorable IL28B, severe liver damage and higher albumin were independently associated with the physician decision to administer triple therapy. Sustained Virological Response after dual therapy was 66.4%, after triple 73.7% (p = 0.14). 142 patients received Telaprevir. The choice of Telaprevir-based therapy was associated with higher Body Mass Index and advanced liver disease. Sustained Virological Response rates were 71.1% after Telaprevir and 76.6% after Boceprevir. CONCLUSIONS Individualizing treatment with available regimens allows to maximize Sustained Virological Response and to reduce the number of patients who remain untreated. High proportion of patients with severe liver damage urgently need Interferon free treatment.

Abstract
BACKGROUND & AIMS The benefit of individualizing treatment for patients with genotype 3 HCV infection on the basis of viral clearance at week 4 (wk4-R) has not been firmly established. METHODS Four hundred and fourteen patients received Peg-interferon alpha-2b plus 1000-1200 mg of ribavirin daily according with body weight > or <75 kg. Patients were randomized to standard 24 weeks (Std24) or to a 12 or 36 weeks variable treatment duration (Var12/36). In the variable treatment arm, patients with or without wk4-R were allocated to either 12 or 36 weeks duration. RESULTS At treatment week 4, HCV RNA was undetectable in 262 patients (63.3%), 136 in the Std24, and 126 in the Var12/36 group (p=0.41). In patients with wk4-R, end-of-treatment (EOT) responses were 80.4% (CI 85.4-95.3) and 97.6% (CI 94.9-99.9) in the two arms, respectively (p=0.019). In patients without wk4-R, corresponding rates were 61.9% (50.6-73.2) and 75.3% (CI 65.9-84.6) (p=0.08). SVR was attained in 302 patients, 71.4% (CI 65.3-77.6) in the St24 group and 74.3% (CI 58.4-80.3) in the variable 12/36 arm. Among patients with wk4-R, SVR was 81.6% (CI 75.1-88.1) and 82.5% (75.9-89.1), respectively. In patients without wk4-R, SVR amounted to 52.1% (CI 40.4-63.7) and 61.7 (CI 51.1-72.3) in the two arms (p=0.25). CONCLUSIONS HCV genotype 3 patients with week4-R may be treated safely with 12 weeks of therapy, provided that sufficiently high doses of ribavirin are administered. For patients still viremic at treatment week 4, SVR rates were numerically higher after 36 weeks of treatment than after the currently recommended 24 weeks.

Abstract
BACKGROUND & AIMS Polymorphisms in the region of the interleukin (IL)-28B gene on chromosome 19 have been associated with peginterferon-alfa-induced clearance of genotype 1 hepatitis C virus (HCV); there are no data for patients with genotype 2 or 3 HCV. We evaluated the effects of IL-28B polymorphisms on response to treatment with peginterferon and ribavirin in a well-characterized cohort of genotype 2/3 patients. METHODS DNA was analyzed from 268 patients (Caucasian: genotype 2, 213; genotype 3, 55). Patients were randomly assigned to groups that received standard duration (24 wk; n = 68) or variable durations of therapy. Patients who received variable durations (VD) and had a rapid virologic response (RVR) were treated for 12 weeks (VD12; n = 122); those without an RVR were treated for 24 weeks (VD24; n = 78). IL-28B genotypes (rs12979860) were analyzed for association with treatment response. RESULTS The frequencies of the IL-28B genotypes were as follows: CC, 37%; CT, 48%; and TT, 15%; 82% of patients with the CC genotype achieved a sustained virologic response (SVR), compared with 75% with the CT and 58% with the TT genotypes (P = .0046). Differences between IL-28B genotypes were greatest among patients who failed to attain RVR (VD24 SVR rates: CC, 87%; CT, 67%; and TT, 29%; P = .0002). Among patients with RVRs (61%), the IL-28B genotype was not associated with SVR (>70% for all IL-28B genotypes). In a multivariable logistic regression model, IL-28B genotype predicted SVR (odds ratio, 1.76; 95% confidence interval, 1.16-2.7). CONCLUSIONS An IL-28B polymorphism was associated with an SVR in patients infected with genotype 2/3 HCV who did not achieve a RVR. Analysis of IL-28B genotype might be used to guide treatment for these patients.

Abstract
BACKGROUND The optimal dose of ribavirin to be used in combination with Peg-IFN in patients with HCV genotypes 2 and 3 undergoing short treatment has not been established. AIM To explore the relationship between starting ribavirin doses, expressed as mg/kg body weight and both rapid viral response at treatment week 4 (RVR) and sustained virological response (SVR) in patients treated for 12-14 weeks with peg-interferon alpha-2b and ribavirin. METHODS A post hoc analysis of data collected from two multicenter clinical trials was performed. Multiple regression analyses were employed to identify independent baseline and on-treatment predictors of RVR and SVR. For each dose of ribavirin, the empirical estimated probability of response was computed and the continuous exposure index was dichotomized by using a recursive partitioning and amalgamation method. RESULTS A nonlinear relationship was ascertained between ribavirin dose and RVR, but not SVR. A dose of 15.2 mg/kg was selected as the best splitting value for discriminating RVR vs. non-RVR. Regression analysis identified low baseline viraemia, genotype 2 and high ribavirin dose as independent prognostic factors for RVR. The likelihood of an SVR was not correlated with baseline ribavirin dose, but was independently predicted by adherence to the full dose throughout treatment and normal platelet counts. CONCLUSIONS Starting high ribavirin doses appears capable of increasing the rate of RVR in patients with HCV genotypes 2 and 3 undergoing short treatment. Maintenance of the full planned dose throughout treatment is essential for achieving optimal SVR rates.

Abstract
UNLABELLED In hepatitis C virus (HCV) genotypes 2 and 3 patients, the high rate of relapse after 12 to 16 weeks of antiviral therapy is the main concern for shortening treatment duration. This study was undertaken to delineate predictors of relapse after short treatment in patients with undetectable HCV RNA at treatment week 4 (RVR), and to report in RVR patients with relapse the sustained virological response (SVR) after a second 24-week course of therapy. RVR patients received pegylated interferon (Peg-IFN) alfa-2b (1.5 microg/kg) and ribavirin (1000-1200 mg/day) for 12 weeks; those who relapsed were re-treated with the same drug doses but for the extended standard duration of 24 weeks. Logistic regression analysis was applied to delineate predictors of relapse by using age, sex, route of transmission, body mass index (BMI), serum alanine aminotransferase (ALT), HCV genotypes, serum HCV RNA levels, and platelet counts as covariates. Of 718 patients with genotypes 2 and 3 who were started on therapy, 496 (69.1%) had undetectable HCV RNA at week 4. Of them, 409 patients (82.5%, CI 79.1-85.8) attained SVR, and 67 (14.1%, CI 10.4-16.5) relapsed. At regression analysis, only platelet count less than 140,000 mm(3) [odds ratio, 2.51; confidence interval (CI), 1.49-4.20] and BMI 30 or higher (odds ratio, 1.7; CI, 1.03-2.70) were independently associated with relapse. Forty-three of 67 patients with relapse agreed to be re-treated, and an SVR was achieved in 30 (70.0%) of them. CONCLUSION We recommend 12 weeks course of therapy for patients with undetectable HCV RNA at treatment week 4, providing they present with no advanced fibrosis and low BMI.

Abstract
UNLABELLED It was hypothesized that in hepatitis C virus (HCV) genotype 1 patients, variable treatment duration individualized by first undetectable HCV RNA is as effective as standard 48-week treatment. Patients (n = 696) received peginterferon alfa-2a, 180 mg/week, or peginterferon alfa-2b, 1.5 mg/kg/week, plus ribavirin, 1000-1200 mg/day, for 48 weeks (standard, n = 237) or for 24, 48, or 72 weeks if HCV-RNA-negative at weeks 4, 8, or 12, respectively (variable, n = 459). Sustained virologic response (SVR) was achieved in 45.1% [95% confidence interval (CI) 38.8-51.4] of the patients in the standard group and in 48.8% (CI 44.2-53.3) of the patients in the variable group (P = 0.37). The percentages of patients who first achieved undetectable HCV RNA at weeks 4, 8, or 12 were 26.7%, 27.8%, and 11.3%, respectively. In the standard treatment group, 87.1%, 70.3%, and 38.1% of patients who first achieved undetectable HCV RNA at 4, 8, or 12 weeks attained SVRs, respectively. In the variable group, corresponding SVR rates were 77.2%, 71.9%, and 63.5%. Low viremia levels and young age were independent predictors of response at week 4 [rapid virologic response (RVR)]. RVR patients with baseline viremia >or=400,000 IU/mL achieved higher SVR rates when treated for 48 weeks rather than 24 weeks (86.8% versus 73.1%, P = 0.14). The only predictive factor of SVR in RVR patients was advanced fibrosis. CONCLUSION Variable treatment duration ensures SVR rates similar to those of standard treatment duration, sparing unnecessary side effects and costs.

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
BACKGROUND/AIMS The aim of the present, open-labelled, controlled study was to determine whether 5 MU of interferon (IFN) alpha 2b combined with a standard dose of ribavirin might increase the rate of viral clearance in all patients with chronic HCV hepatitis or at least in those with an unfavourable genotype. METHODS A total of 298 previously untreated patients with chronic hepatitis C were randomized to 5 or 3 MU of interferon alpha 2b 3 times per week with 1000-1200 mg of ribavirin daily (148 and 150 patients, respectively). Patients were treated for 12 months and observed for 6 months posttreatment. RESULTS In patients infected with HCV genotype 1, the sustained virologic response was 37.8% (95% CI 27.3-48.1) with IFN 5 MU and 19.2% (95% CI 10.1-28.2) with IFN 3 MU (P=0.008). Out of 45 sustained responders with genotype 1, 31 (69%) had received 5 MU and 14 (31.1%) the standard 3 MU dose of IFN in combination with ribavirin (P=0.01). Of the 86 responders infected with genotype non-1, 39 (45.3%) were from the 5 MU IFN group and 47 (54.6%) were from the 3 MU IFN group; these figures were not significant. At the multivariate analysis of baseline features for all patients, the variables with an independent effect for a sustained response were genotype non-1 (odds ratio (OR) 3.98, 95% CI 2.36-6.40), and the histological grading (score 0-2) (OR 2.48, 95% CI 1.12-5.51) and staging (score 0-1) (OR 1.73, 95% CI 1.02-2.95). For patients with genotype 1 only the high regimen of IFN entered the model (OR 2.39, 95% CI 1.13-5.05), whereas for patients with genotype non-1 an age of <40 years (OR 2.64, 95% CI 1.23-5.70) and staging (score 0-1) (OR 2.38, 95% CI 1.07-5.28) were independent predictors of a sustained response. CONCLUSIONS Our study suggests that when treating naive patients with genotype 1, there is a significant increase in the rate of sustained virologic clearance by increasing the dose of IFN given in combination with ribavirin.

Abstract
The aim of this study was to compare, in an open-label study, the efficacy and safety of a combination of interferon (IFN) and amantadine (AMA) with that of IFN alone in previously untreated patients with chronic hepatitis C. A total of 200 patients were randomized to 6 MU of IFN-alpha2a 3 times per week, with 200 mg of AMA daily (n = 99) or to an identical dose of interferon alpha2a (n = 101). Patients were treated for 12 months and observed for 6 months' posttreatment. At the completion of treatment, 28.7% of patients in the monotherapy group and 45.5% in the combination group had a virologic response (P =.014). At 6 months' posttreatment, a sustained virologic response was observed in 16.8% (95% CI: 9-23) of patients with IFN alone versus 29.3% (95% CI: 19-37) of patients who were treated with combination therapy (P =.036). In each of the 2 treatments, genotype was the only predictive parameter for a sustained response. At the logistic regression analysis, therapy and genotype were the only 2 parameters with an independent predictive value. In the combination group, at examination of month 3, hepatitis C virus (HCV)-RNA status had a 97.6% (95% CI: 93-102) positive predictive value and a 50% (95% CI: 37-63) negative predictive value for a sustained virologic clearance. A substantial proportion of naïve patients with chronic hepatitis C have an end-of-treatment and end-of-follow-up virologic and biochemical response to a combination of IFN and AMA. This new treatment appears safe and well tolerated.

Abstract
BACKGROUND In chronic hepatitis C the schedule of interferon (IFN), 3 MU thrice weekly (tiw) plus ribavirin (1000-1200 mg/daily) needs further evaluation, as IFN dosages >3 MU achieve better responses. AIMS To compare the efficacy of 5 MU tiw of IFN with (96 patients) or without ribavirin (96 patients) for 12 months in naïve patients, to evaluate the effect of baseline features on the response to therapy, and to determine a reliable point in time during treatment to predict non-response. RESULTS Sustained virologic response was 20.8% (95% CI 13-29) with IFN monotherapy and 54.2% (95% CI 44-64) with combination (P = 0.0001), the relapse rate 39.4% (95% CI 23-56) and 9% (95% CI 1-16) (P = 0.0007), and the combined rate of sustained biochemical and virologic response 22.7% (95% CI 14-31) and 60.5% (95% CI 50-71) (P = 0.0001), respectively. Patients given combination therapy were more likely to respond regardless of baseline features. Apart from genotype non-1, predictive factors for IFN monotherapy were ineffective in predicting response to combination therapy. Using logistic regression analysis, IFN-ribavirin was the strongest predictor of response (X2 = 21.3; P = 0.0001). Viral persistence at month 3 of therapy was a more accurate predictor than aminotransferase values for non-response to IFN monotherapy but not to combination therapy (positive predictive values of 98 and 82%, respectively). CONCLUSION In this study, 5 MU of IFN combined with a standard dose of ribavirin has yielded the highest rate of sustained response reported to date. Further dose finding studies are warranted.
