Neurologic complications of immunosuppressive agents.

The immunosuppressive agents that are an integral part of organ transplantation serve to protect grafts from rejection as well as to prevent or treat GVHD. They include CsA, corticosteroids, OKT3 monoclonal antibody, HDARA-C, azathioprine, and ATG. Of these, all but azathioprine and ATG have direct neurologic complications that are due to the drugs themselves and not just excessive immune suppression. With increasing success in solid organ and bone marrow transplantation and increasing patient survival, one can expect to see more patients who suffer neurologic toxicity.
