Guidelines for irradiation of blood and blood components to prevent post-transfusion graft-vs.-host disease in Japan.

Author information

Division of Blood Transfusion, Chiba University Hospital, Chiba, Japan.


The Japanese Red Cross analysed the results of questionnaires sent in 1993 regarding post-transfusion graft-vs.-host disease (PT-GVHD) from hospitals; the majority of patients with PT-GVHD in 1993 were transfused for cardiovascular or cancer surgery, and about 10 patients had died yearly from PT-GVHD in the following few years. The Japan Society of Blood Transfusion (JSBT) organized a subcommittee for the prevention of PT-GVHD, and issued a fourth version of guidelines for the irradiation of blood to prevent PT-GVHD. These guidelines recommended transfusion of irradiated blood for cardiosurgery, cancer surgery, elderly recipients and severe trauma, as well as congenital immunodeficient recipients, newborn infants and other immunocompromised patients. Also recommended was irradiation not only of blood within 72 h after collection but also of blood stored for 14 days. Reported PT-GVHD has diminished to a few cases in recent years.
