We studied a group of 64 patients undergoing cardiac surgery for the occurrence of post-transfusion hepatitis during a follow-up period of 5 months. They received blood units (packed red cells in saline-adenine-glucose medium and/or fresh frozen plasma exclusively) from 447 volunteer donors. Post-transfusion hepatitis was identified in 5 patients: 1 patient had cytomegalovirus hepatitis and the remaining 4 cases were defined, by exclusion, as non-A, non-B hepatitis (with prevalence and incidence rates of 80% and 6.25% respectively). We found no statistically significant differences between the numbers of transfused blood product units in patients who developed non-A, non-B hepatitis as compared to those who did not. Our analysis of the predictive effectiveness of alanine aminotransferase and anti-HBc antibodies screening in blood donors to prevent non-A, non-B post-transfusion hepatitis led to the following conclusions: we failed to confirm the association between anti-HBc in blood donors and enhanced risk of non-A, non-B hepatitis in recipients since no case developed among patients receiving blood products from anti-HBc positive donors. So, 20 donors (4.5%) would have been discarded without any reduction of the incidence of non-A, non-B hepatitis. we could not confirm nor exclude the possibility that screening donor blood for elevated alanine aminotransferase levels would have reduced the number of non-A, non-B hepatitis in recipients.
