Use of Foscarnet Therapy for EBV Infection following Control of PTLD with Enhancement of Cellular Immunity in a Lung-Transplant Recipient

Abstract EN

Posttransplant lymphoproliferative disorder (PTLD) is a serious complication following solid organ transplantation with an annual incidence rate of 3–5% in lung-transplant recipients.

Pathogenesis indicates a strong association with functional over-immunosuppression and EBV infection.

Clinical improvement is generally observed with reduction in immunosuppression intensity alone.

We present a case of a 24-year-old woman with EBV-associated PTLD following lung transplant where decreasing the immunosuppression improved PTLD but was ineffective against controlling the EBV infection.

Foscarnet in combination with immunoglobulins was successfully administered to cause a remission of the EBV infection.

This is the second case reported of a persistent EBV infection after reducing immunosuppression levels and evidence of PTLD remission that required foscarnet for EBV infection control.
