A 2 year and 8 month old CMV-negative boy suffering from stage III neuroblastoma underwent ABMT in first very good partial remission. He acquired early CMV infection on day +5, followed by consecutive graft failure and severe sepsis, and the clinical course deteriorated. Between days +16 and +21, he received seven leukocyte concentrates (LC) collected from a healthy, but CMV-IgG-seropositive relative stimulated with G-CSF (filgastrim, 5 microg/kg/day). A median of 5.7 x 10(10) neutrophils/m2/day (range, 1.2-8.3) were transfused, corresponding to a T cell number of roughly 4 x 10(8) CD3+ cells/kg/day. After infusion of the LCs, PCR analysis became negative for CMV and the patient received his rescue bone marrow. One year after ABMT, he is in complete remission and in good clinical condition. Our results suggest that the T cells infused together with the irradiated leukocytes played a major role in eradicating the CMV infection in this patient.
