Effect of highly active anti-retroviral therapy and hepatitis C virus co-infection on serum levels of pro-inflammatory and immunoregulatory cytokines…

2006

ABSTRACTThis study aimed to determine the effect of highly active anti-retroviral therapy (HAART) and hepatitis C virus (HCV) co-infection on peripheral levels of interleukin (IL)-2, IL-10, IL-12 (p70), IL-18 and soluble tumour necrosis factor receptor type II (sTNFRII). Serum levels were monitored for a 1-year period in 25 patients infected with human immunodeficiency virus-1 (HIV-1) who were naive for HAART at the initiation of the study, and in four HIV-1-infected long-term non-progressors. Serum levels of both IL-18 and sTNFRII at baseline were significantly higher in HIV-1-infected patients than in controls. Baseline levels of IL-18 and sTNFRII were not significantly different in long-…

Risk Factors and Outcome among a Large Patient Cohort with Community-Acquired Acute Hepatitis C in Italy

2006

Background The epidemiology of acute hepatitis C has changed during the past decade in Western countries. Acute HCV infection has a high rate of chronicity, but it is unclear when patients with acute infection should be treated. Methods To evaluate current sources of hepatitis C virus (HCV) transmission in Italy and to assess the rate of and factors associated with chronic infection, we enrolled 214 consecutive patients with newly acquired hepatitis C during 1999-2004. The patients were from 12 health care centers throughout the country, and they were followed up for a mean (+/- SD) period of 14+/-15.8 months. Biochemical liver tests were performed, and HCV RNA levels were monitored. Result…

Viral and host factors in the prediction of response to interferon-alpha therapy in chronic hepatitis C after long-term follow-up.

1998

Acute infection with hepatitis C virus (HCV) develops into a chronic hepatitis in about 50-70% of patients. Treatment of these patients with interferon-alpha (IFN-alpha) results in a sustained long-term response in only 15-20% but causes numerous unwanted side-effects in a higher percentage of patients. The aim of our study was to define host or viral parameters that would allow identification of responders and non-responders to IFN-alpha prior to the onset of treatment. We studied a group of 87 patients suffering from chronic hepatitis C who were treated with IFN-alpha. After long-term follow-up, 18 patients (21%) showed a sustained response to IFN-alpha therapy (normalization of serum tra…

Therapy expectations and physical comorbidity affect quality of life in chronic hepatitis C virus infection.

2007

Summary.  Hepatitis C virus (HCV) infection is associated with a significant reduction of health related quality of life (QOL), the causes and mechanisms of which are still unknown. To explore whether treatment history could affect QOL, we examined patients with detectable HCV viraemia who had a different therapeutic background. Two hundred sixty-four consecutive subjects with chronic HCV infection and detectable viraemia were enrolled. Of these, 163 were untreated patients, 43 were relapsers, 58 were nonresponders (NR) to nonpegylated interferon (IFN) therapy. To assess QOL, three self-report instruments were employed: the Short Form-36 (SF-36), the Chronic Liver Disease Questionnaire (CLD…

HCV genotypes in Sicily: is there any evidence of a shift?

2009

The distribution of HCV strains in any area is characterized by a relative prevalence of one genotype, and a number of less prevalent types. In some Western countries a change from the prevalent HCV genotype 1 to genotypes 3 and 4 has been reported in the last decade. In order to assess possible variations of the distribution of HCV genotypes in Sicily, a southern region of Italy, a hospital-based cohort, collected prospectively, of 3,209 subjects with chronic HCV infection was surveyed, comparing the distribution of HCV genotypes during two consecutive periods, from 1997 to 2002 and from 2003 to 2007, according to age and gender. The results show that genotype 1b, which has been historical…

The cellular immune responses induced in the follow-up of interferon-α treated patients with chronic hepatitis C may determine the therapy outcome

1998

Abstract Background/Aims: To study whether the host's immune response determines viral clearance in chronic hepatitis C, virological markers and antigen-specific T cell reactions were analysed in 30 chronic HCV carriers followed up during interferon-α therapy, 11 untreated anti-HCV positive individuals and 10 healthy controls. Methods: Proliferative T helper cell responses to recombinant HCV core and non-structural antigens were monitored by 3 H-thymidine uptake assay and compared to quantitative viraemia levels and HCV genotypes. Results: Of the 30 treated patients, six had sustained complete responses (20%), another six were transient therapy responders (20%) and 18 were non-responders (6…

Peginterferon alfa-2b plus weight-based ribavirin for 24 weeks in patients with chronic hepatitis C virus genotype 1 with low viral load who achieve …

2012

. In chronic hepatitis C (CHC), treatment duration may be individualized according to time to first undetectable hepatitis C virus (HCV) RNA, with patients who attain undetectable HCV RNA early in treatment being candidates for shorter regimens. The aim of this study was to determine the relapse rate in patients with CHC genotype (G) 1 infection and low baseline viral load who achieved undetectable HCV RNA by week 4 [rapid virologic response (RVR)] when treated for 24 weeks. This was an open-label, multicentre, noninterventional study. Adult patients with G1 CHC infection and baseline viral load <600,000 IU/mL who attained RVR were treated with peginterferon alfa-2b (1.5 mu g/kg/week) plus …

Ethical assessment of hepatitis C virus treatment: The lesson from first generation protease inhibitors

2015

Abstract Since chronic hepatitis C has mostly become curable, issues concerning choice and allocation of treatment are of major concern. We assessed the foremost ethical issues in hepatitis C virus therapy with 1st generation protease inhibitors using the personalist ethical framework within the health technology assessment methodology. Our aim was to identify values at stake/in conflict and to support both the physicians’ choices in hepatitis C therapy and social (macro-) allocation decision-making. The ethical assessment indicates that: (1) safety/effectiveness profile of treatment is guaranteed if its use is restricted to the patients subgroups who may benefit from it; (2) patients shoul…

Anti-hepatitis A virus seroprevalence and seroconversion in a cohort of patients with chronic viral hepatitis

2002

Abstract Background. Patients with chronic hepatitis C infected by hepatitis A virus have a substantial risk of fulminant hepatitis or death, while the course of hepatitis A virus is uncomplicated in most subjects with chronic hepatitis B. Aim. To evaluate the prevalence of anti-hepatitis A virus antibodies and the incidence of hepatitis A virus seroconversion in a nationwide sample of 530 patients with chronic hepatitis B and/or hepatitis C infection initially susceptible to this infection after a follow-up of some years. Results. The overall anti-hepatitis A virus prevalence was 85.7%, with no difference between males and females. By the age of 50 years, almost all patients were found to …

Transfusion-associated chronic hepatitis C: alpha-n1 interferon for 6 vs. 12 months.

1996

Abstract Aims: To compare the long-term effects of brief and prolonged therapy with alpha-n 1 interferon for transfusion-associated chronic hepatitis C. Methods: One hundred and sixteen subjects (male/female 4868, mean age 46.9 years) were studied. Sixty patients were randomised to brief treatment (group 1: interferon 5 Mu/msq. t.i.w. for 2 months, then 3 Mu/msq. t.i.w. for 4 months), and 56 to prolonged treatment (group 2: interferon 5 Mu/msq. t.i.w. for 2 months, then 3 Mu/msq. t.i.w. for 10 months). All were followed for 12 months after stopping interferon. Results: The early response rate was 47.4% (Group 1 [45%], Group 2 [50%]). No "breakthrough" reactivations were observed. The early …
