Viral infections constitute an important problem for transplant recipients and their physicians. Often the balance between adequate and over-immunosuppression is hard to find and therapeutic drug monitoring might be a welcome adjunct in the management of transplant patients. We report four renal transplant recipients with extra-ordinary presentations of viral disease who were all treated with mycophenolate mofetil and in whom high mycophenolic acid (MPA) trough levels were found. High MPA levels may reflect over-immunosuppression resulting in infectious complications.
