Summary:Epstein-Barr virus-associated lymphoproliferative disorders have been frequently reported as a complication of solid organ and allogeneic bone marrow transplantation. Their occurrence is rare after autologous bone marrow transplantation (BMT) with only five published reports in the literature. We report two cases of posttransplant lymphoproliferative disorder occurring after autologous BMT for Hodgkin's disease and non-Hodgkin's lymphoma. Post-transplant lymphoproliferative disorders can occur after autologous BMT and should be included in the differential diagnosis of patients with persistent fever, adenopathy or pulmonary infiltrates. Keywords: PTLD; EBV; BMT; lymphoproliferation Post-transplant lymphoproliferative disorders (PTLD) are a well recognized complication of solid organ transplantation and are due to an unrestricted proliferation of Epstein-Barr virus (EBV)-infected lymphocytes occurring with immunosuppression.1,2 The majority of PTLD are of B cell origin; however, cases of T cell PTLD and Hodgkin's disease have been reported. [2][3][4] Pathologically, the lymphoproliferation encompasses a spectrum ranging from plasma cell hyperplasia and polymorphic B cell hyperplasia (similar to infectious mononucleosis), to monomorphic infiltrates indistinguishable from malignant lymphoma. 2,5,6 The risk for developing PTLD after solid organ transplantation is increased 20-to 150-fold compared to the incidence of lymphoma in the general population. The risk is greatest within the first year after transplant. [7][8][9] PTLD have been reported after allogeneic bone marrow transplantation (BMT) with an increased incidence after T cell depletion. 10,11 In contrast to the experience with PTLD after allogeneic BMT, PTLD after autologous BMT is infrequent.12-15 We present two patients who developed PTLD after autologous BMT.Correspondence: Dr RJ Hauke, Department of Internal Medicine, University of Nebraska Medical Center, 600 S 42nd Street, Omaha NE 68198-8065, USA Received 30 September 1997; accepted 27 January 1998
Case reports
Patient 1A 27-year-old male with stage IIA nodular sclerosing Hodgkin's disease relapsed after treatment with doxorubicin, bleomycin, vincristine and dacarbazine. He received two cycles of mechlorethamine, vincristine, procarbazine and prednisone (MOPP) and then received high-dose cyclophosphamide, carmustine and etoposide followed by autologous BMT. Following transplant, 4500 cGy consolidation radiation therapy was given to the mediastinum.On day +87, he developed dyspnea and bilateral pulmonary infiltrates. Bronchoalveolar lavage was nondiagnostic. Low grade fevers and dyspnea persisted after empiric antibiotic therapy.After referral to our institution, a video-assisted thoracoscopy was performed. Pneumocystis carinii pneumonia (PCP) and cytomegalovirus (CMV) pneumonitis were diagnosed.Sulfamethoxazole/trimethroprim, ganciclovir (2.5 mg/kg every 8 h i.v.), immune globulin and prednisone were administered with prompt clinical improvement. Recurrent pneumothoraces required pleural stri...
