Peginterferon alfa-2b plus ribavirin for naïve patients with genotype 1 chronic hepatitis C: a randomized controlled trial

2004

We assessed the effectiveness and safety of an induction dose of peginterferon alfa-2b (PEG-IFN) plus ribavirin for initial treatment of patients with genotype 1 chronic HCV infection in a randomized, controlled, multicenter trial.Three hundred and eleven naïve patients infected with genotype 1 and chronic hepatitis were randomly assigned to 48-week treatment with PEG-IFN once weekly (80-100 micrograms depending on body weight for 8 weeks, followed by 50 micrograms for the next 40 weeks), or standard interferon alfa-2b (IFN) 6 million units on alternate days, both in combination with ribavirin (1000-1200 mg/day).PEG-IFN plus ribavirin significantly increased sustained virological response (…

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 …

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 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…

Association of C677T polymorphism in MTHFR gene, high homocysteine and low HDL cholesterol plasma values in heterozygous familial hypercholesterolemi…

2010

Aim: to investigate the association of C677T polymorphism in the methylene tetrahydrofolate reductase (MTHFR) gene, homocysteine plasma values (Hcy), and plasma HDL cholesterol in heterozy-gous familial hypercholesterolemia (hFH).Methods: One hundred and twenty-five hFH subjects were studied. Plasma lipid, lipoprotein, vitamin B12, folic acid and Hcy values were determined. C677T polymorphism in the MTHFR gene was detected by SSCP-PCR. Genetic diagnosis of FH was determined by a three-step protocol using SSCP-PCR, Southern blot, long PCR and automatic sequencing.Results: We found significant differences in plasma HDL-C (CC 1.39±0.34, CT 1.33±0.39 and TT 1.14±0.26 mmol/L, p=0.028) between th…

PTFE mesh in renal allograft compartment syndrome.

2006

We report a case of anuria in a 42-year-old female kidney transplant patient that occurred secondary to extrinsic compression from a large kidney being placed extraperitoneally in a small iliac fossa. Prompt reexploration in the immediate postoperative period resulted in salvage of the graft with restoration of kidney function. The abdominal wall was reconstructed using prosthetic mesh, which decreased the compartment pressure within the iliac fossa sufficiently to allow the renal vein patency and the kidney perfusion. We think that this tension-free surgical technique should be applied in those cases in which the retroperitoneal space is less than the size of the kidney to avoid renal allo…

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…
