Monitoring of EBV-DNA load and CsA levels in patient 1.

A 5-year-old boy with ALL received a TCD bone marrow graft from a mismatched unrelated donor. The posttransplant course was uncomplicated. A limited acute GVHD of the skin was treated with oral prednisolone. Four infusions of EBV-CTLs were given starting from day +79 after BMT without exacerbation of GVHD. Cyclosporin A was continued during follow-up.
