The HEP-NET B/C co-infection trial: A prospective multicenter study to investigate the efficacy of pegylated interferon-α2b and ribavirin in patients…

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…

Current practice of chronic hepatitis B treatment in Southern Italy

2012

Abstract Background Treatment choice for chronic HBV infection is a continuously evolving issue, with a wide range of options. We aimed to evaluate the current practice of HBV therapies in the real world in Southern Italy. Methods A prospective study enrolling over a six month period (February–July 2010) all consecutive HBsAg positive subjects, never previously treated, referred to 16 liver units in two Southern Italy regions (Calabria and Sicily). Results Out of 247 subjects evaluated, 116 (46.9%) had HBV-DNA undetectable or lower than 2000 UI/ml. There were 108 (43.7%) inactive carriers, 103 (41.7%) chronic hepatitis, and 36 (14.6%) liver cirrhosis. Antiviral treatment was planned in 94 (…

Role of a 48-week pegylated interferon therapy in hepatitis B e antigen positive HIV-co-infected patients on cART including tenofovir: EMVIPEG study.

2014

In hepatitis B e antigen (HBeAg) positive-HIV co-infected patients treated with combined antiretroviral therapy (cART), including tenofovir disoproxil fumarate (TDF), the rate of HBe seroconversion remains low. Whether adding pegylated interferon alfa (PegIFN) could increase the likelihood of HBeAg loss and HBe seroconversion has not been assessed.A 48-week PegIFN therapy was added to HBeAg positive-HIV co-infected patients on TDF and emtricitabine, or lamivudine for at least 6 months. The primary endpoint was HBV sustained response: HBe seroconversion with undetectable HBV DNA levels 24 weeks after completing PegIFN therapy (W72).Fifty-one patients (49 men, median age 46 years, range: 32-6…

Pegylated alpha-interferon-2a plus ribavirin compared with pegylated alpha-interferon-2b plus ribavirin for initial treatment of chronic hepatitis C …

2008

Background and aim We assessed whether the two regimens of pegylated alpha-interferon-2b (PEG-IFN-alpha2b) plus ribavirin and pegylated alpha-interferon-2a (PEG-IFN-alpha2a) plus ribavirin showed differences in terms of sustained virological response, withdrawal due to side-effects and dose adjustment requirements in the treatment of naive chronic hepatitis C virus (HCV) patients. Methods A prospective non-randomized, open-label comparison was made of naive HCV-infected patients undergoing standard 24- or 48-week treatment with two PEG-IFN combined with weight-based dosing regimen of ribavirin (PEG-IFN-alpha2a/ribavirin, n = 91; PEG-IFN-alpha2b/ribavirin, n = 92). Results Sustained virologi…

Long-Term Follow-Up of Patients with Chronic Hepatitis C after Interferon-Alpha Treatment

1996

In this study, 72 patients with chronic hepatitis C virus (HCV) were followed prospectively for a mean period of 27 months after interferon treatment. Fifty-seven percent (20/35) of the patients with complete response, 18/20 with HCV-RNA-negative serum, had a sustained biochemical remission. Reactivation was seen in 43% of these patients after a mean follow-up of 7.3 months. A late relapse after more than 12 months of follow-up occurred in only 2/15 patients. Patients with a long-term complete response had significantly lower pretreatment serum HCV RNA levels than complete responders with relapse (106,239 vs. 345,649 mEq/ml, p = 0.0213). A delayed sustained biochemical remission was seen in…

Post-marketing of disease modifying drugs in multiple sclerosis: an exploratory analysis of gender effect in interferon beta treatment.

2009

Background: There are a few and conflicting results from randomised controlled trials (RCTs) pertaining to the influence of gender in response to currently used disease modifying drugs in Multiple Sclerosis (MS). Observational studies may be especially valuable for answering effectiveness questions in subgroups not studied in RCTs. Objective: To conduct a post-marketing analysis aimed to evaluate the gender effect on Interferon beta (IFN beta) treatment response in a cohort of relapsing (RR) MS patients. Methods: A cohort of 2570 IFN beta-treated RRMS was prospectively followed for Lip to 7 years in 15 Italian MS Centers. Cox proportional hazards regression models were used to assess gender…

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…

Interferon as treatment for acute hepatitis C

1996

The efficacy of short-course (three months), low-dose (3 million units three times a week) interferon as treatment for acute hepatitis C was evaluated in a meta-analysis of controlled trials. Nine studies (five randomized and four nonrandomized) found by MEDLINE search were eligible for analysis. The outcomes assessed were the rate of patients with normal serum aminotransferases (all trials) and without HCV RNA in blood (five trials) after posttreatment follow-up. Eight trials compared interferon to no treatment, and one compared different schedules of interferon. The methodological quality of the studies was high. However, all trials had been planned for a short-term evaluation based on bi…

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…
