Hyperacute graft-versus-host disease (GVHD), which progresses severely and rapidly, was observed in three patients with acute leukemia transplanted with bone marrow cells from human leukocyte antigens (HLA)-identical and mixed leukocyte reactions (MLR)-negative siblings. Hyperacute GVHD developed in these patients within 7 days after bone marrow transplantation (BMT) and was rapidly aggravated inspite of cyclosporin A (CyA) and short-term methotrexate (MTX) prophylaxis and treatment with bolus methylprednisolone (mPSL). These patients showed markedly increased serum interleukin-6 (IL-6) levels after BMT, whereas other cytokines such as interferon gamma (IFN gamma), tumor necrosis factor alpha (TNF alpha), and IL-2 were not increased compared with pretreatment levels. These findings suggest that markedly increased IL-6 levels may be related to hyperacute GVHD.
