Cutaneous graft-versus-host reaction lacks evidence of cutaneous cytomegalovirus by the immunoperoxidase technique.
Sixty skin biopsy specimens from 21 bone-marrow transplant patients were evaluated for the presence of cytomegalovirus (CMV) using two monoclonal antibodies to early and late antigens. Each patient had at least one biopsy showing an acute graft-versus-host reaction (GVHR), grade 2, and one positive culture for CMV from blood, bone marrow or urine. In no case could CMV antigens be identified in biopsies showing an acute or chronic cutaneous GVHR or in any other of the skin biopsies obtained from these patients. While CMV may play a role in immunologic events culminating in graft-versus-host disease (GVHD), this immunoperoxidase study did not reveal evidence of viral antigens in tissue displaying features of cutaneous GVHR.
