Etiological Spectrum of Post-Transfusion Hepatitis

Abstract

Frequent occurrence of post-transfusion hepatitis continues despite screening for Australia antigen in blood before transfusion and elimination of commercial donor sources. The majority of these cases appears unrelated to hepatitis B virus. Preoperative, acute, and convalescent serra were screened for evidence of hepatitis B, hepatitis A, Epstein-Barr, and cytomegalovirus exposure in 34 cardiac surgery patients developing post-transfusion hepatitis postoperatively. Four patients showed evidence of hepatitis B infection and 3 patients developed significant antibody titer rises to cytomegalovirus. No patient showed evidence for acute hepatitis A infection postoperatively in response to blood transfusions. Epstein-Barr virus was also not responsible for any cases of post-transfusion hepatitis. Presently available laboratory methods failed to implicate hepatitis A, Epstein-Barr, or cytomegalo-virus in the majority of non-B post-transfusion hepatitis cases. This suggests that identification and characterization of additional hepatitis-producing agents will be required to define further the epidemiology of post-transfusion hepatitis and develop measures for its prevention.
