Graft-versus-host disease (GVHD) in leukemia patients following allogeneic bone marrow transplantation (BMT) has a lot of demerits but it also has a merit, namely graft-versus-leukemia effect. We reported the results of our recent trials on prevention, treatment and induction of GVHD, and prevention of viral infection after BMT. The results were as follows: 1) Twenty-four percent of patients who received prophylactic administration of cyclosporine and short term methotrexate still developed II degree-IV degree acute GVHD. 2) Patients with I degree or II degree acute GVHD showed good clinical courses. But, most patients with III degree GVHD gradually developed chronic GVHD. All patients with IV degree GVHD died of GVHD or infection. 3) Mizoribine and deoxyspergualin were effective for steroid-resistant GVHD. 4) Bestatin was administered to recipients who did not develop GVHD until day 30 after BMT. An interim report suggests that bestatin may induce chronic GVHD and suppress the relapse of leukemia. 5) Oral administration of gamma-globulin may prevent viral enteritis. Intravenous administration of anti-cytomegalovirus monoclonal antibody may prevent cytomegalovirus pneumonia. |
