To the Editor: Transplantation of solid-organ allografts caninduce long-term donor-type microchimerism1 by migration ofpassenger mononuclear cells2,3. So far, microchimerism has beendescribed only in immunologically stable patients after liveror kidney transplantation4. An association between persistentchimerism and graft acceptance has been suggested. We describepersistent donor-type microchimerism in a patient with therapy-resistantgraft rejection late after liver transplantation.
In December 1984 a 17-year-old boy (HLA-A1,11; B7,8; Cw7; DRw15,w17)received a liver transplant (Donor 1: HLA-A1,25; B18,w52; DR1,4)for end-stage primary sclerosing cholangitis. After an earlyepisode of rejection that responded to steroids, he had an . . . [Full Text of this Article]
