Induction of hyperacute graft-vs-host disease after donor leukocyte infusions.

Infusions of leukocytes obtained from the original bone marrow donor is a new approach for treating patients who have a relapse of leukemia after allogeneic bone marrow transplantation. Up to 90% of patients who achieved remission developed graft-vs-host disease (GVHD). However, any description of the clinical and histologic features in these cases is lacking.
