    Abstract:
    Post-transplant lymphoproliferative disorders (PTLD) are a group of heterogeneous lymphoid proliferations in chronic immunosuppressed recipients which appear to be related to Epstein Barr Virus (EBV). Receptor EBV seronegativity, use of antilymphocyte antibodies and CMV disease have been identified as risk factors that may tigger development of PTLD. We have studied the incidence of PTLD and its relationship with EBV in 588 adult renal transplant recipients who were transplanted in our hospital from 1988 to 2001. We have also evaluated the diagnostic and therapeutic methods used, the risk factors and outcome of the patients who developed PTLD. We identified 8 recipients (4 males and 4 females), range from 18 to 67 years (mean age 45.6 years) with a median time between grafting and PTLD of 4.1 years (0.1-7 years), who developed PTLD (1.3%). Only 1 patient received OKT3 and had CMV disease, two of them (25%) had been treated with hight doses of prednisolone, another was EBV seronegative, but the rest of them (50%) had no risk factors. Two patients were diagnosed at autopsy, the diagnosis of 5 was based on the histology of biopsy and the last one by CT scans of chest-abdomen and cytology. The presence of EBV in the lymphoproliferative cells was assessed in 5 out of the 7 studied patients (71.4%). The outcome of our recipients was poor. Five out of 8 patients died shortly after diagnosis as a direct consecuence of PTLD and another of an infectious complication of the treatment (75%). The 2 patients alive started dialysis and 1 of them died 2 years later of a non-related cause. In conclusion, PTLD is a relatively frequent disease with a poor prognosis in renal transplant patients. It seems to have a close relationship with EBV and can develop in the absence of the classical risk factors.
