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

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…

Long-term interferon-α treatment of children with chronic hepatitis delta: A multicentre study

We assessed the efficacy of prolonged interferon-alpha (IFN) therapy in children with chronic hepatitis caused by hepatitis delta virus (HDV) by treating 26 paediatric cases with IFN-alpha 2b (5 MU m-2, then 3 MU m-2 three times weekly for 12 (medium-term group MTG) or 24 months (long-term group, LTG). Compliance and tolerability were acceptable. At the end of therapy a complete biochemical response [normalization of alanine aminotransferase (ALT)] occurred in 12 children (5/13 in MTG and 7/13 in LTG). A relapse occurred after stopping IFN in 10 cases (five in MTG and five in LTG). Two patients from the LTG had normal liver function tests during 12 months of follow-up. Six of the eight hepa…

Cholestasis in newborn infants with perinatal asphyxia

Objective: The aim of this study was to characterize the liver involvement in infants who have both neonatal asphyxia and neonatal cholestasis. Methods: We describe four asphyctic newborn infants (three born at term) who developed early (age 3.8 ± 2.1 days) intrahepatic neonatal cholestasis and in whom tests for causes of neonatal liver damage were negative. Results: The clinical picture and course were benign and similar to that of sporadic 'idiopathic' neonatal hepatitis. Clinical signs and abnormal liver function tests tended to normalize within the first year of life in all. Conjugated bilirubin became normal at 6 months after the onset of cholestasis, while liver enzymes tended towards…

Epidemiological profile of 806 Italian children with hepatitis C virus infection over a 15-year period

BACKGROUND & AIMS: The natural course of chronic hepatitis C (CHC) in children is not well understood. The aim of this study was to assess the long-term course of CHC in a large sample of otherwise healthy children. METHODS: From 1990 to 2005, 504 consecutive antihepatitis C virus (HCV)-positive children were enrolled at 12 centers of a national observatory and were followed up retrospectively/prospectively. RESULTS: Putative exposure was perinatal in 283 (56.2%) cases, parenteral in 158 (31.3%), and unknown in 63 (12.5%). At baseline, 477 (94.6%) cases were HCV RNA seropositive, 118 (24.7%) of which were treated with standard interferon alpha. Ten years after putative exposure, the out…
