B-cell lymphoproliferative disorders in solid-organ transplant patients: detection of Epstein-Barr virus by in situ hybridization.
B-cell lymphoproliferative disorders (BLPDs) occur in approximately 2% of transplant recipients and are frequently fatal. Indirect serologic evidence has implicated Epstein-Barr virus (EBV) as an etiologic factor in these lesions. Direct evidence of the presence of EBV in these lesions has been obtained in relatively few cases. We used in situ hybridization (ISH) with a probe for the BamHI-W region of the EBV genome to study 52 tissue specimens from 28 solid-organ transplant patients who had BLPD. Epstein-Barr virus-infected lymphoid cells were identified in 26 of these 28 patients. The two patients without ISH evidence of EBV infection showed no distinctive clinical, morphologic, or serologic features. Previous filter-hybridization studies of these two patients had demonstrated evidence of EBV infection. Seven additional transplant patients without evidence of BLPD were studied as controls and showed no evidence of EBV in their lymphoid cells by ISH. These data provide further support for the etiologic role of EBV in the pathogenesis of posttransplantation lymphoproliferative disorders.
