Introduction and objective. The introduction of a vaccine against hepatitis B virus (HBV) for newborn babies in Italy in 1991, extended to 12-year-old children for the first 12 years of application, has been a major achievement in terms of the prevention of HBV infection. The objective of this study was to analyse the long-term immunogenicity and effectiveness of HBV vaccination among healthcare students with different working seniorities. Materials and method. A cross-sectional observational study of undergraduate and postgraduate students attending the Medical School of the University of Palermo was conducted from January 2014 – July 2016. HBV serum markers were performed with commercial …

Hepatitis B virus infection in native versus immigrant or adopted children in Italy following the compulsory vaccination.

2001

Background: Compulsory vaccination of children against hepatitis B virus (HBV) infection was introduced in Italy in 1991. Patients and Methods: To evaluate the current importance of pediatric HBV infection, we studied 359 HBsAg-positive children admitted to 16 centers in Italy from 1991 to 1998. 185 patients were natives of Italy and 174 (39 immigrants and 135 adopted) came from highly endemic countries (eastern Europe: 60.9%, Asia: 16.7%, Africa: 14.9% and Central and South America: 5.7%). Results: Transaminase levels were moderately altered in both Italian (mean 134 UI/l) and foreign children (mean 168 UI/l). In total, 77% of Italian children and 88% of foreign children tested HBeAg posit…

Influence of universal HBV vaccination on chronic HBV infection in Italy: Results of a cross-sectional multicenter study

2017

Background and Aim The universal hepatitis B vaccination for infants and 12-year-old adolescents (the latter limited to the first 12 years of application) was launched in Italy in 1991. Twenty-three years later we evaluated the impact of the vaccination campaign on the burden of HBsAg-positive chronic liver diseases (CLD). Material and Methods 513 HBsAg-positive chronic carriers referring to 16 Italian liver units were investigated and compared with HBsAg carriers enrolled in previous surveys. Results The proportion of inactive carriers decreased from 20.0% in 2001 to 3.3% in 2014, while that of cirrhotic patients increased from 22.6 to 33.2%. Regarding the age class 0–33 (fully covered by …
