Summary:EBV-associated lymphoproliferative disorder (LPD) is a rare but serious complication in marrow transplant recipients. A 31-year-old Japanese woman in the second chronic phase of CML received an allogeneic BMT from her HLA 2-locus-incompatible 62-year-old father. Around day +200, she developed EBV-LPD of the right parieto-temporal lobe which caused slowly progressive left hemiparesis. Two courses of donor lymphocyte transfusions (DLT) of 10 6 CD3 + T cells/kg of body weight failed to suppress her central nervous system (CNS) EBV-LPD. The patient died of recurrent blastic crisis of CML. This case suggests that DLT may be ineffective for the treatment of CNS EBV-LPD. Keywords: Epstein-Barr virus-associated lymphoproliferative disorder; donor lymphocyte transfusion; central nervous system EBV-associated lymphoproliferative disorder (LPD) is a rare but serious complication in marrow transplant recipients. 1,2 Although there are reports of successful treatment of polyclonal or oligoclonal proliferations with agents such as interferon-␣ and intravenous ␥-globulin, high-dose acyclovir, and anti-B-cell MoAb, 3-5 monoclonal disease has remained refractory to treatment in marrow transplant recipients.Recently, donor lymphocyte transfusions (DLT) have been shown to be an effective treatment for EBV-LPD. 6,7 We report the case of a Japanese woman, who developed EBV-LPD of the right cerebrum following allogeneic BMT and who was then treated with DLT.
Case reportA 31 year-old Japanese woman was admitted to our hospital for the treatment of myeloid blastic crisis (BC) of CML Correspondence: Dr K Nagafuji, Department of Hematology, Hara Sanshin General Hospital, 1-8 Taihaku-machi, Hakata-ku, Fukuoka 812, Japan Received 4 August 1997; accepted 22 December 1997 in July 1996. She entered the second chronic phase after treatment with vincristine and prednisolone. The patient had no HLA-identical siblings, nor were there any HLAidentical unrelated donors in the Japan Marrow Donor Program. Because of the poor prognosis in BC, we decided to perform a BMT using her HLA 2-locus-incompatible 62-year-old father as donor. The donor was seropositive for human T cell leukemia virus type 1 (HTLV-1), while the recepient was seronegative. 8 Both the recipient and the donor were seropositive for EBV (VCA IgG ×40 VCA IgM Ͻ×10 EBNA ×10, VBCA IgG ×640 VCA IgM Ͻ×10 EBNA ×10, respectively).The pre-transplant conditioning consisted of BU 4 mg/kg orally in divided doses daily on days −8 to −5, and CY 50 mg/kg i.v. daily on days −4 to −2. Because of ABO major incompatibility, bone marrow mononuclear cells isolated by density-gradient centrifugation (1.8 × 10 8 /kg of body weight) were given. Tacrolimus (FK506; Fujisawa, Osaka, Japan) in combination with MTX was used for GVHD prophylaxis. Grade II GVHD of the skin developed on day +11 but this responded well to high-dose methylprednisolone therapy. Granulocytes exceeded 0.5 × 10 9 /l on day +16, and platelets exceeded 50 × 10 9 /l on day +26. Prolonged administration of immunosuppressive agents wa...
