Hypertension develops soon after organ transplantation using cyclosporine- or FK506-based immunosuppression. Sustained rises in blood pressure require intervention to reduce the risk of intracranial bleeding and other cardiovascular complications. Antihypertensive treatment is complicated by reduced renal function and potential interference with absorption and/or metabolism of cyclosporine or FK506. To manage early and long-term hypertension related to immunosuppression with cyclosporine or FK506 and prednisone following orthotopic liver transplantation, a comprehensive nurse-managed hypertension clinic was developed. Blood pressure, heart rate, and antihypertensive and immunosuppressive regimens were evaluated according to a standard protocol at 1, 4, 12, 24, and 36 months after orthotopic liver transplantation. Data indicate that posttransplantation hypertension develops within the first months after orthotopic liver transplantation and persists indefinitely. If comprehensively managed by the hypertension nurse-clinician, the percentage of controlled hypertension patients can increase over time.
