Prospective Study of Post Transfusion Hepatitis (Transfusion-transmitted Viruses Study)

摘要

To complete the analysis of major factors potentially influencing risk of non-A, non-B viral hepatitis, recipient characteristics were analyzed. Sex, age, prior transfusion, prior hepatitis B experience, and number of transfusions administered had no influence. The last finding seems explained by protective interaction among multiple units. In stepwise regression, only donor characteristics emerged as important. A donor characteristic not previously analyzed was subtype of hepatitis B virus strain among donors positive for antibody to hepatitis B surface antigen. The findings were negative except for a subgroup for whom age was more closely related to outcome.
