title: Post-transfusion hepatitis: the role of hepatitis B antibody.
abstract: Aliquots from units of blood previously transfused as part of a prospective post-transfusion hepatitis (PTH) study were rescreened for the presence of hepatitis B antibody (anti-HBS) to determine the effect of transfusion of such material. Anti-HBS was more commin in commercial blood. Infusion of anti-HBS was not associated with an increased or decreased risk of PTH, hepatitis B, or hepatitis B (HB) exposure. Receipt of anti-HBS did not modify the hepatitis which occurred. Receipt of large amounts of anti-HBS may be associated with an increased incidence of HB events. Preexisting anti-HBS was not only not protective against PTH, but more PTH (67% versus 40%) and hepatitis B (47% versus 12%) were seen in those patients with it.
