title: Importance of recall and follow-up screening for chronic hepatitis C in children receiving blood products prior to 1990 in Japan.
abstract: The objective was to detect chronic hepatitis C virus infection in recipients of blood products using retrospective analysis by recall and enrollment of recipients. 226 patients who received blood products for open heart surgery from January 1983 to June 1992 were examined for HCV antibody by using a second generation assay and liver function test. 22 (14%) of the 161 patients who received blood products before November 1989 had detectable HCV antibody, but none of the 65 recipients receiving blood products after 1990, the year the Japanese blood bank began to screen for HCV-antibody. Abnormal alanine aminotransferase (ALT) levels, more than 25 iu/L, during the chronic phase of HCV infection was recognized in nine of 22 (41%) seropositive patients. The liver function test and second generation HCV antibody in the serum are effective markers to screen for chronic hepatitis C in blood product recipients transfused before 1990.
