Body Mass Index and Liver Stiffness Affect Accuracy of Ultrasonography in Detecting Steatosis in Patients With Chronic Hepatitis C Virus Genotype 1 I…

2013

Background & Aims: Few studies have evaluated the accuracy of ultrasonography in detecting steatosis in patients with chronic hepatitis C. We assessed its accuracy in detecting steatosis and factors that affect its diagnostic performance in consecutive patients with chronic hepatitis C virus genotype 1infection. Methods: We analyzed data from 515 patients with chronic hepatitis C, confirmed by liver biopsy, assessing anthropometric, biochemical, metabolic, virologic, and ultrasonography features. Transient elastography was performed to measure liver stiffness. Steatosis was identified with ultrasonography based on detection of a bright liver echo pattern. Results: Ultrasonography identified…

Optimizing patient referral and center capacity in the management of chronic hepatitis C: Lessons from the Italian experience

2019

Abstract Aims In 2017 the Italian Drug Agency (Agenzia Italiana del Farmaco, AIFA) revised the criteria for access to therapy for patients with chronic hepatitis C as part of a three-year plan to eradicate HCV. We conducted a Delphi study to determine strategies to identify and treat patients with HCV and to develop through a shared pathway, a model to manage patient referral and optimize prescription center capacity with the overall aim of increasing access to therapy. Methods The process took place in two phases – Phase I (January 2017), before the criteria for treatment of HCV were revised and Phase II (May 2017) when AIFA developed a framework for the eradication of HCV infection in Ita…

HCV infection and oral lichen planus: a weak association when HCV is endemic.

2004

Oral lichen planus (OLP), an immune-mediated disorder, has been reported as an extra-hepatic manifestation of Hepatitis C virus (HCV) infection, especially in HCV hyperendemic areas such as southern Europe and Japan. The aim of this study was to investigate from an epidemiological standpoint whether HCV infection is an important factor affecting the relative risk of OLP in a Mediterranean population or whether this relates to the degree of HCV endemicity. Two cohorts of OLP patients resident in two different regions of southern Italy (Campania and Sicily; n = 859) were evaluated for HCV infection status and categorized into five age classes to respective region-matched controls. No signific…

Early discontinuation of ribavirin in HCV-2 and HCV-3 patients responding to Peg-interferon alpha-2a and ribavirin

2008

Guidelines for the treatment of patients infected with hepatitis C virus of genotypes 2 and 3 (HCV-2 and HCV-3, respectively) recommend a 24-week course of Peg-interferon (Peg-IFN) alpha-2a combined with ribavirin, despite 50% of patients in registration trials attaining a sustained virologic response (SVR) following Peg-IFN alpha-2a monotherapy. The aim of this study was to delineate patient characteristics that might help to identify individuals likely to benefit from ribavirin discontinuation. One hundred and forty-four HCV-2- and HCV-3-infected patients initiated Peg-IFN alpha-2a (180 microg/week) and ribavirin (1000 or 1200 mg/day); those with viral clearance at week 4 were randomized …

Effects of IL28B rs12979860 CC Genotype on Metabolic Profile and Sustained Virologic Response in Patients With Genotype 1 Chronic Hepatitis C

2013

Patients with genotype 1 chronic hepatitis C (G1 CHC) frequently develop steatosis and insulin resistance (IR), caused by metabolic and viral factors. These accelerate the progression of liver disease and reduce the response to therapy. A sustained virologic response (SVR) to therapy in patients with G1 CHC is associated strongly with polymorphisms near the interleukin-28B (IL28B) gene, but the interaction between IL28B genotype and IR, and their combined effects on SVR, have not been defined. We tested the association between the IL28B rs12979860 single-nucleotide polymorphism and metabolic features, including IR, and evaluated their effects on SVR.We performed genotype analysis of IL28B r…

Intravenous natural beta-interferon in white patients with chronic hepatitis C who are nonresponders to alpha-interferon.

1998

Objectives: α-Interferons (α-IFN) have been shown to be effective in the treatment of chronic viral C hepatitis, but their efficacy remains unsatisfactory. Recently natural β-interferon (β-IFN) administered by intravenous infusion has been used successfully. Methods: To evaluate the efficacy and safety of intravenous β-IFN administration we treated 20 patients with histologically proven chronic hepatitis C who were nonresponders to at least two previous courses of α-IFN treatment. All patients received 6 million units (MU) of natural human fibroblast β-IFN by drip infusion, 6 times per wk for 8 wk and were followed up for 6 months after suspension of treatment. Results: Five patients (25%) …

Individualized treatment duration for hepatitis C genotype 1 patients: a randomized controlled trial

2008

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 …

Retinol-binding protein 4: a new marker of virus-induced steatosis in patients infected with hepatitis C virus genotype 1.

2008

Retinol-binding protein 4 (RBP4) is an adipocytokine associated with insulin resistance (IR). We tested serum levels of RBP4 to assess its link with steatosis in patients with genotype 1 chronic hepatitis C (CHC) or nonalcoholic fatty liver disease (NAFLD). Nondiabetic patients with CHC (n = 143) or NAFLD (n = 37) were evaluated by liver biopsy and anthropometric and metabolic measurements, including IR by the homeostasis model assessment. Biopsies were scored by Scheuer classification for CHC, and Kleiner for NAFLD. Steatosis was tested as a continuous variable and graded as absent-mild <30%, or moderate-severe > or =30%. Thirty nondiabetic, nonobese blood donors served as controls. …

Hepatitis C virus RNA profiles in chronically infected individuals: do they relate to disease activity?

1999

Fluctuations of hepatitis C virus (HCV)-RNA serum levels were monitored in a multicenter study in 76 chronic HCV carriers who had been followed longitudinally without receiving antiviral therapy to assess their relation with the course of liver disease activity. Forty-four patients had normal transaminases over more than 2 years, while 32 additional patients had fluctuating levels. Viral load was measured in serial serum samples prospectively collected for 10 to 12 months in 54 patients and in sera stored yearly up to 8 years in an additional 22 patients. In patients tested monthly, a lesser extent of fluctuations was detected in cases with constantly normal transaminases as compared with t…

2008

Background/Aims The efficacy of pegylated interferon alpha and ribavirin in HBV/HCV co-infected patients is unknown. Methods Nineteen patients with chronic HBV/HCV co-infection (HBsAg and HCV-RNA positive; 10 HCV-genotype 1; 9 HCV-genotype 2 or 3) were included in this prospective multicenter pilot study. Baseline HBV-DNA was negative in 13 individuals. All patients received weight-adjusted PEG-IFN-α2b and ribavirin for 48 weeks. Results In the intent-to-treat analysis, a biochemical and an HCV-RNA response were observed in 12 and 14 patients, respectively (63% and 74%). At the end of the treatment as well as at the end of the follow-up the HCV-RNA response was 93% (14/15) in patients adher…
