IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Torino.
AperTO è l'archivio istituzionale Open Access destinato a raccogliere, rendere visibile e conservare la produzione scientifica dell'Università degli Studi di Torino.
EnglishThe characteristics and evolution of hepatitis C virus (HCV) infection were retrospectively investigated in a study of 224 HCV RNA-seropositive white children who were consecutively recruited at 7 European centers in 1980-1998. At presentation, all patients were positive for antibodies to hepatitis C virus, 87% were asymptomatic, and 48% had alanine aminotransferase (ALT) levels that were < or =2 times the upper limit of the range considered to be normal. Of 200 children followed for 1-17.5 years (mean follow-up +/- standard deviation [SD], 6.2+/-4.7 years), only 12 (6%) achieved sustained viremia clearance and normalization of the ALT level. In 92 revised liver biopsy specimen analyses, the mean fibrosis score (+/-SD) was 1.5+/-1.3 for children <15 years of age and 2.3+/-1.2 for children > or =15 years of age (range, 0-6 years; P<.01). Pediatric HCV infection is usually mild, but few patients, especially those who are perinatally infected, clear viremia in the medium-term follow-up. Conversely, the higher rates of fibrosis observed in older patients suggest the possibility of an insidious progression of HCV-associated liver disease.

| Abstract: | The characteristics and evolution of hepatitis C virus (HCV) infection were retrospectively investigated in a study of 224 HCV RNA-seropositive white children who were consecutively recruited at 7 European centers in 1980-1998. At presentation, all patients were positive for antibodies to hepatitis C virus, 87% were asymptomatic, and 48% had alanine aminotransferase (ALT) levels that were < or =2 times the upper limit of the range considered to be normal. Of 200 children followed for 1-17.5 years (mean follow-up +/- standard deviation [SD], 6.2+/-4.7 years), only 12 (6%) achieved sustained viremia clearance and normalization of the ALT level. In 92 revised liver biopsy specimen analyses, the mean fibrosis score (+/-SD) was 1.5+/-1.3 for children <15 years of age and 2.3+/-1.2 for children > or =15 years of age (range, 0-6 years; P<.01). Pediatric HCV infection is usually mild, but few patients, especially those who are perinatally infected, clear viremia in the medium-term follow-up. Conversely, the higher rates of fibrosis observed in older patients suggest the possibility of an insidious progression of HCV-associated liver disease. | |
