Allogeneic bone marrow transplantation (BMT) is a treatment modality with the potential of curing otherwise lethal diseases. The predominant indications for BMT are haematological malignancies. In BMT alloreactivity plays a pivotal role for the outcome. ⋯ Analyzing all 48 patients the risk of acute GvHD > or = grade II and TRM was significantly higher with HTLp frequencies > 1:100,000 and there was a trend towards a higher risk of relapse with low HTLp frequencies < 1:400,000. Patients in the intermediate HTLp frequency group 1:100,000-1:400,000 had a trend towards improved survival. The HTLp frequency seems to detect clinically significant differences in alloreactivity, that can be useful in donor selection, graft-engineering, T cell add-back and the pharmacological immunosuppression used after BMT.
