HCV-induced immune responses influence the development of operational tolerance after liver transplantation in humans.

2014

Pathogen-induced immune responses prevent the establishment of transplantation tolerance in experimental animal models. Whether this occurs in humans as well remains unclear. The development of operational tolerance in liver transplant recipients with chronic hepatitis C virus (HCV) infection allows us to address this question. We conducted a clinical trial of immunosuppression withdrawal in HCV-infected adult liver recipients to elucidate (i) the mechanisms through which allograft tolerance can be established in the presence of an ongoing inflammatory response and (ii) whether anti-HCV heterologous immune responses influence this phenomenon. Of 34 enrolled liver recipients, drug withdrawal…

Konzentrationsverhalten der Plasmaglycosphingolipide bei akuter Hepatitis

1977

Im menschlichen Blutplasma kommen hauptsachlich vier neutrale Glycosphingolipidfraktionen vor: Monohexosyl-, Dihexosyl-, Trihexosyl- und Tetrahexosylceramid. Bei Patienten mit akuter Hepatitis (n=21) sind in der akuten Phase die vier Glycosphingolipidfraktionen im Plasma gegenuber einem gesunden Kontrollkollektiv (n=23) erhoht. Mit Ausnahme der Trihexosylceramidfraktion last sich die Erhohung statistisch sichern. Gleichzeitig kommt es in der akuten Phase der Hepatitis zu einer statistisch signifikanten Cholesterin- und Triglyceriderhohung. Es wird gefolgert, das die Erhohung der Glycosphingolipide im Plasma bei der akuten Hepatitis im Zusammenhang mit der Fettstoffwechselstorung auftritt un…

Evolving clinical landscape of chronic hepatitis B: A multicenter Italian study.

2009

The aim of the study was to evaluate the characteristics of chronic hepatitis B with special reference to the geographical origin of the patients and to the prevalence of HBeAg and viral and non-viral co-factors of liver disease. A cross-sectional multicenter survey was undertaken, which enrolled 1,386 HBsAg chronic carriers observed consecutively in 21 referral centers over a 6-month period. The prevalence of HBeAg in patients was 11%; the presence of HBeAg was associated independently with a younger age and co-infection with HIV. Anti-HDV, anti-HCV, or anti-HIV antibodies were detected in 8.1%, 6.5%, and 2%, respectively. However, among the patients first diagnosed during the study period…

Prophylaxis and treatment of hepatitis B in immunocompromised patients.

2007

The literature on hepatitis B virus (HBV) in immunocompromised patients is heterogeneous and referred mainly to the pre-antivirals era. Today a rational approach to the problem of hepatitis B in these patients provides for: (a) the evaluation of HBV markers and of liver condition in all subjects starting immunosuppressive therapies (baseline), (b) the treatment with antivirals (therapy) of active carriers, (c) the pre-emptive use of antivirals (prophylaxis) in inactive carriers, especially if they are undergoing immunosuppressive therapies judged to be at high risk, (d) the biochemical and hepatitis B surface antigen (HBsAg) monitoring (or universal prophylaxis, in case of high risk immunos…

Retreatment with interferon plus ribavirin of chronic hepatitis C non-responders to interferon monotherapy: a meta-analysis of individual patient dat…

2002

Background and aims: Retreatment with a combination of α interferon (IFN) plus ribavirin of patients with chronic hepatitis C who did not respond to IFN monotherapy has not been assessed in large controlled studies. Methods: To assess the effectiveness and tolerability of IFN/ribavirin retreatment of non-responders to IFN and to identify predictors of complete (biochemical and virological) sustained response, we performed a meta-analysis of individual data on 581 patients from 10 centres. Retreatment with various IFN schedules (mean total dose 544 mega units) and a fixed ribavirin dose (1000–1200 mg/daily depending on body weight) was given for 24–60 (mean 39.5) weeks. Results: Biochemical …

Forecasting Hepatitis C liver disease burden on real-life data. Does the hidden iceberg matter to reach the elimination goals?

2018

Abstract Background & Aims Advances in direct‐acting antiviral treatment of HCV have reinvigorated public health initiatives aimed at identifying affected individuals. We evaluated the possible impact of only diagnosed and linked‐to‐care individuals on overall HCV burden estimates and identified a possible strategy to achieve the WHO targets by 2030. Methods Using a modelling approach grounded in Italian real‐life data of diagnosed and treated patients, different linkage‐to‐care scenarios were built to evaluate potential strategies in achieving the HCV elimination goals. Results Under the 40% linked‐to‐care scenario, viraemic burden would decline (60%); however, eligible patients to treat w…
