FK 506 associated disorders in liver transplantation.
Immunosuppressive regimens are usually required for patients receiving organ transplants. The development of a post-transplant lymphoproliferative disorder is an infrequent complication of such therapy. FK 506 is a new immunosuppressant agent that has recently been used in patients receiving organ transplantation. This report describes a 20 month old Saudi child who developed post-transplant lymphoproliferative disorder while receiving FK 506 following liver transplantation. Such a complication has been recognized with cyclosporine but has not been well addressed as yet with FK 506. The child also developed progressive renal complications. There was also a difficulty in interpreting the results for IgM antibodies to different viruses. The overall features of progressive renal toxicity and those of lymphadenopathy, hepatosplenomegaly, fever, neutropenia and thrombocytopenia reversed following discontinuation of FK 506 therapy. It is concluded that all the above complications, though reversible, may well be linked to the new immunosuppressant agent FK 506.
