2021

Abstract Introduction and objectives Implementation of a one-step strategy for diagnosis of active Hepatitis C virus (HCV) infection would encourage the early diagnosis and reduce the time to access antiviral treatments. The aim of this study was to evaluate the impact of a HCV one-step diagnosis compared to the traditional two-step protocol in terms of the time required for patients to be seen by specialists and the time taken to start antiviral treatment. Material and methods A comparative study was carried out to assess two diagnostic algorithms (one-step and two-step) for active HCV infection. Serological markers were quantified using the same serum sample to determine both anti-HCV ant…

Factors that predict response of patients with hepatitis C virus infection to boceprevir

2012

Background & Aims Little is known about factors associated with a sustained virologic response (SVR) among patients with hepatitis C virus (HCV) infection to treatment with protease inhibitors. Methods Previously untreated patients (from the Serine Protease Inhibitor Therapy 2 [SPRINT-2] trial) and those who did not respond to prior therapy (from the Retreatment with HCV Serine Protease Inhibitor Boceprevir and PegIntron/Rebetol 2 [RESPOND-2] trial) received either a combination of peginterferon and ribavirin for 48 weeks or boceprevir, peginterferon, and ribavirin (triple therapy) after 4 weeks of peginterferon and ribavirin (total treatment duration, 28–48 wk). A good response to interfer…

Characteristics of liver cirrhosis in Italy: Evidence for a decreasing role of HCV aetiology

2017

Previous cross-sectional studies have shown that hepatitis C virus (HCV) infection had been the main agent associated with liver cirrhosis in Italy. Abstract BACKGROUND: Previous cross-sectional studies have shown that hepatitis C virus (HCV) infection had been the main agent associated with liver cirrhosis in Italy.

Effectiveness and safety of ombitasvir, paritaprevir, ritonavir ± dasabuvir ± ribavirin: An early access programme for Spanish patients with genotype…

2017

Over the last 5 years, therapies for hepatitis C virus (HCV) infection have improved significantly, achieving sustained virologic response (SVR) rates of up to 100% in clinical trials in patients with HCV genotype 1. We investigated the effectiveness and safety of ombitasvir/paritaprevir/ritonavir +/- dasabuvir in an early access programme. This was a retrospective, multicentre, national study that included 291 treatment-naive and treatment-experienced patients with genotype 1 or 4 HCV infection. Most patients (65.3%) were male, and the mean age was 57.5years. The mean baseline viral load was 6.1 log, 69.8% had HCV 1b genotype, 72.9% had cirrhosis and 34.7% were treatment-naive. SVR at 12 w…

Characteristics of patients with hepatitis C virus-related chronic liver diseases just before the era of oral direct-acting antiviral therapy in Italy

2018

Background In 2017, oral direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection became available free of charge for all HCV-RNA-positive patients, irrespective of their fibrosis stage. Aim The aim of this study was to evaluate the characteristics of HCV-related chronic liver disease (CLD) in Italy just before the introduction of DAA therapy. Patients and methods Patients with CLD were enrolled in two national surveys conducted in 2001 and in 2014. The two surveys prospectively enrolled patients aged older than 18 years referring to Italian liver units throughout the country using a similar clinical approach and analytical methods. Results Out of the 12 564 patie…

Real-world outcomes in patients with chronic hepatitis C: primary results of the PROBE study.

2014

BACKGROUND This large prospective multicentre cohort study aimed to improve knowledge of therapy for chronic hepatitis C (CHC) in real clinical practice. METHODS A diverse population of adults with CHC including patients with comorbid conditions, laboratory abnormalities and demographic features [comorbidities or special populations (CSP)] who were under-represented or excluded from peginterferon registration studies was treated with peginterferon α-2a (40 kDa) or α-2b (12 kDa) plus ribavirin at the investigator's discretion. RESULTS During the study, 5399 treatment-naive patients [2527 (46.8%) with CSP] received peginterferon α-2a (n=3513, 65.1%) or peginterferon α-2b (n=1886, 34.9%). The …

Modulation of epitope-specific anti-hepatitis C virus E2 (anti-HCV/E2) antibodies by antiviral treatment

2006

The dynamic features of three specific anti-hepatitis C virus (HCV) antibody subpopulations directed against different conformational epitopes of the viral E2 protein (HCV/E2) have been evaluated in patients with primary and persistent HCV infection; the three subpopulations are present in patients infected with different HCV genotypes and have shown a different activity using a pseudovirus neutralization assay (antibodies e301 and e137 exhibiting high neutralizing activity, while antibody e509 enhancement of HCV infectivity). In sequential samples from five patients with primary HCV infection and different virological outcome, all samples tested negative with the single exception of the e5…

Evaluating the risk of hepatitis B reactivation in patients with haematological malignancies: is the serum hepatitis B virus profile reliable?

2009

Background/Aim: Patients with an occult hepatitis B virus (HBV) infection undergoing deep immunosuppression are potentially at risk of HBV reactivation. In order to assess whether a polymerase chain reaction (PCR) assay for HBV DNA in serum could be used to predict the reactivation of an occult HBV infection, we performed a retrospective study in a cohort of Sicilian patients with oncohaematological diseases. Methods: We studied by a highly sensitive ad hoc nested PCR for serum HBV DNA 75 HBsAg-negative oncohaematological patients requiring chemotherapy. Results: Thirty-three patients (44%) were HBV seronegative (anti-HBc and anti-HBs negative) and 42 patients (56%) were HBV seropositive (a…

Clinical features and comorbidity pattern of HCV infected migrants compared to native patients in care in Italy: A real-life evaluation of the PITER …

2021

Background: Direct-acting antivirals are highly effective for the treatment of hepatitis C virus (HCV) infection, regardless race/ethnicity. We aimed to evaluate demographic, virological and clinical data of HCV-infected migrants vs. natives consecutively enrolled in the PITER cohort. Methods: Migrants were defined by country of birth and nationality that was different from Italy. Mann-Whitney U test, Chi-squared test and multiple logistic regression were used. Results: Of 10,669 enrolled patients, 301 (2.8%) were migrants: median age 47 vs. 62 years, (p < 0.001), females 56.5% vs. 45.3%, (p < 0.001), HBsAg positivity 3.8% vs. 1.4%, (p < 0.05). Genotype 1b was prevalent in both gro…
