Chronic hepatitis B in Italy: New features of an old disease - Approaching the universal prevalence of hepatitis B e antigen-negative cases and the e…

2008

We evaluated 1336 hepatitis B surface antigen-positive subjects consecutively observed in 79 Italian hospitals over a 6-month period. The proportion of hepatitis B e antigen-negative cases was 86.4%, that of patients coinfected with hepatitis D virus was 9.7%, and the rate of patients coinfected with hepatitis C virus was 16.8%. Multiple logistic regression analysis showed that age >49 years, alcohol abuse, and anti-hepatitis D virus and anti-hepatitis C virus positivity were independent predictors of progression to liver cirrhosis. © 2007 by the Infectious Diseases Society of America.

Hepatitis B Virus-Associated Hepatocellular Carcinoma

2022

Hepatitis B virus (HBV) is DNA-based virus, member of the Hepadnaviridae family, which can cause liver disease and increased risk of hepatocellular carcinoma (HCC) in infected individuals, replicating within the hepatocytes and interacting with several cellular proteins. Chronic hepatitis B can progressively lead to liver cirrhosis, which is an independent risk factor for HCC. Complications as liver decompensation or HCC impact the survival of HBV patients and concurrent HDV infection worsens the disease. The available data provide evidence that HBV infection is associated with the risk of developing HCC with or without an underlying liver cirrhosis, due to various direct and indirect mecha…

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…
