To the Editor.—

The American Red Cross is initiating the screening of donor blood for high alanine aminotransferase (ALT) levels to reduce the incidence of posttransfusion hepatitis. Non-A, non-B hepatitis, probably caused by several viruses, is the major cause of posttransfusion hepatitis. Thirty percent of patients with posttransfusion hepatitis are symptomatic, and some develop chronic hepatic disease. Hepatitis B has been virtually eliminated as a source of posttransfusion hepatitis by testing donor blood for hepatitis B surface antigen.

Aach et al¹ prospectively followed up 1513 transfusion recipients and found that the incidence of posttransfusion hepatitis was directly related to the ALT concentration in blood donors. The overall attack rate for non-A, non-B hepatitis was 10%, but recipients of donor units with an ALT concentration of 60 U/L or greater had a 45% attack rate. The direct relationship between transfusion hepatitis and donor ALT levels was confirmed by Alter et . . . [Full Text PDF of this Article]
