Current practice of hepatitis C treatment in Southern Italy.

2010

Abstract Background Only a small proportion of subjects referring to hospitals for hepatitis C virus (HCV) positivity receives antiviral therapy. Aim To evaluate the rate of antiviral treatment and the causes for no treatment in HCV-RNA positive subjects seen in hospital settings. Patients and methods A prospective study enrolling over a 6-month period (February–July 2009) all consecutive anti-HCV positive subjects initially referred (naive patients) to 12 liver units in Southern Italy for HCV treatment. Results Out of 608 subjects evaluated, 74 (12.2%) had no detectable HCV-RNA in the serum and thus were excluded. Of the remaining 534 HCV-RNA positive subjects, 357 (66.9%) were not treated…

Impact of liver steatosis on the antiviral response in the hepatitis C virus-associated chronic hepatitis.

2006

: Background/Aim: Liver steatosis (LS) has been variably associated with chronic hepatitis C (CHC) but whether it affects sustained virological response to antiviral treatment and by what mechanisms is a question still under debate, at least for some genotypes. The aim of this work was to assess the frequency of LS, its relationship with host and viral factors and to what extent it can influence the response to antiviral combination therapy with pegylated interferon (INF)+ribavirin in a group of patients with CHC from a single center. Patients: One hundred and twelve patients with histologically proven CHC were treated with Peg INF-α 2a 180 μg a week subcutaneously for 48 weeks plus ribavir…

Long term clinical outcome of chronic hepatitis C patients with sustained virological response to interferon monotherapy.

2004

Background: The key end point for treatment efficacy in chronic hepatitis C is absence of detectable virus at six months after treatment. However, the incidence of clinical events during long term follow up of patients with sustained virological response is still poorly documented and may differ between the Eastern and Western world. Aims: To assess clinical end points during long term follow up of European patients with a sustained virological response to interferon monotherapy. Methods: Meta-analysis of individual patient data from eight European protocolled follow up studies of interferon treatment for chronic hepatitis C. Results: A total of 286 sustained virological responders and 50 b…

Different doses of consensus interferon plus ribavirin in patients with hepatitis C virus genotype 1 relapsed after interferon monotherapy: a randomi…

2006

AIM: To assess the efficacy of different schedules of consensus interferon (CIFN) plus ribavirin in retreating chronic hepatitis C patients who relapsed after recombinant interferon (rIFN) monotherapy. METHODS: Forty-five patients (34 males and 11 females) with chronic hepatitis due to hepatitis C virus (HCV) genotype 1 who relapsed after a previous course of rIFN monotherapy were randomized to receive 9 μg CIFN three times per week for 52 wk (group A, n = 22) or 18 μg CIFN three times per week for 52 wk (group B, n = 23) in combination with ribavirin 800 to 1200 mg daily for 52 wk (according to body weight). Virological response was evaluated at week 24 (EVR), at the end of treatment (ETR)…

Gender differences in human immunodeficiency virus–related oral lesions: An Italian study

2001

Abstract Objective: The purpose of this study was to investigate the relationship between oral lesions and gender, age, CD4+ cell count, human immunodeficiency virus-1 (HIV-1) viral load, antiretroviral therapy, and route of transmission in a group of HIV-infected (HIV+) persons from the Mediterranean region. Study Design: The participants in this study were HIV+ adults who sought dental care between January 1999 and June 1999 in the Department of Oral Medicine (University of Palermo, Italy). Results: One hundred thirty-six HIV+ adults came in for an initial oral examination. Their mean age was 35.2 years (SD ± 7.97), and 33% were women. Their mean CD4+ cell count was 325.3 × 106 /L (SD ± 2…

Consensus interferon and ribavirin for patients with chronic hepatitis C and failure of previous interferon-alpha therapy.

2006

BACKGROUND The efficacy of consensus interferon (CIFN), a synthetic IFN with optimised in vitro activity, was assessed in chronic hepatitis C virus (HCV) patients who had failed the pretreatment with interferon-alpha (IFNalpha) and ribavirin. METHODS One hundred and three patients after non-response (n=69) or relapse (n=34) to IFNalpha+/-ribavirin were randomly assigned to high-dose induction (CIFN 27-->9 microg daily for 24 weeks, 9 microg t.i.w. for 24 weeks) or low-dose treatment (CIFN 18 microg t.i.w. for 12 weeks, 9 microg t.i.w. for 36 weeks); each with ribavirin 800 mg/day. Follow-up was 24 weeks. RESULTS Non-responder patients treated with high-dose induction had higher early virolo…

Improved Responses to Pegylated Interferon Alfa-2b and Ribavirin by Individualizing Treatment for 24–72 Weeks

2011

Guidelines recommend that patients with chronic hepatitis C virus (HCV) infection be treated with pegylated interferon and ribavirin for 24, 48, or 72 weeks, based on their virologic response to treatment. We investigated the effects of treating patients for individualized durations.We treated 398 treatment-naïve patients who had HCV genotype 1 infections with pegylated interferon alfa-2b and ribavirin for 24, 30, 36, 42, 48, 60, or 72 weeks (mean of 39 weeks, termed individualized therapy); the duration of therapy was determined based on baseline viral load and the time point at which HCV RNA levels became undetectable (measured at weeks 4, 6, 8, 12, 24, and 30). Results were compared with…

Long-term course of interferon-treated chronic hepatitis C

1998

Abstract Background/Aims: To evaluate whether sustained response to α-interferon improves clinical outcome in patients with chronic hepatitis C. Methods: A cohort of 410 consecutive patients (65% with chronic hepatitis, 35% with cirrhosis) were treated with α-interferon in two trials (mean follow-up 62.1 months, range 7–109 months). All were serum HCV RNA positive before therapy and received first 10 then 5 million units of α-2b or α-n1 interferon three times weekly for 6 to 12 months. Sustained response was defined as normal aminotransferases 12 months after stopping interferon. Results: Sixty-two patients (15.1%: 54 with chronic hepatitis, eight with cirrhosis) were sustained responders. …

Predicting Early and Sustained Virological Responses in Prior Nonresponders to Pegylated Interferon alpha-2b Plus Ribavirin Retreated With Peginterfe…

2013

GOALS: To evaluate the predictive value of complete early virological response (cEVR) on sustained virological response (SVR) following retreatment with peginterferon alpha-2a (40 kDa) plus ribavirin in previous nonresponders to peginterferon alpha-2b (12 kDa). BACKGROUND: In the randomized multinational retreatment with Pegasys in patients not responding to PegIntron therapy study, a 72-week regimen of peginterferon alpha-2a (40 kDa) plus ribavirin improved SVR rates over a standard 48-week regimen in previous nonresponders to peginterferon alpha-2b (12 kDa). cEVR, defined as hepatitis C virus RNA <50 IU/mL at treatment week 12, was an important predictor of SVR. STUDY: We conducted an exp…
