The high risk of chronic liver disease in multitransfused juvenile hemophiliac patients.
Eighty-seven asymptomatic children with either hemophilia A or B were treated before they were 21 years of age. Seventy-two received factor concentrates and 15 cryoprecipitate or fresh-frozen plasma only. Thirty-two of the 72 in the former group have persistently elevated alanine aminotransferase values compared to one of 15 in the latter group. In a subset of children treated with factor concentrates before five years of age, four of seven are chronically HBsAg positive. Liver biopsies were performed in 13 of the 32 asymptomatic patients with abnormal ALT values in the fraction group. It is recommended that until further data become available, children with mild hemophilia and all less than 5 years of age should receive only cryo or FFP.
