- Abstract
Background: Conventional immunosuppression for heart transplantation is associated with various adverse effects. Tacrolimus monotherapy (TM) is an alternative strategy that minimizes exposure to additional immunosuppressants., Methods: We retrospectively reviewed clinical data for all adult transplant recipients between January 1, 1996 and May 1, 2004. Clinical outcomes were analyzed according to immunosuppressive regimen., Results: A total of 167 heart transplants were performed at our center. Eight patients died before receiving calcineurin inhibitors and were excluded from analysis. The mean follow-up for the 159 surviving patients was 1,520 +/- 78 days. Ninety of 124 patients initially treated with tacrolimus and corticosteroids were weaned to TM without the use of an anti-proliferative agent (Group A), resulting in an overall success rate of 75% at an average of 271 +/- 18 days after transplant. The remaining 69 recipients were treated with other tacrolimus- or cyclosporine-based regimens (Group B). Survival was significantly greater in Group A. The prevalence of high-grade rejection within the first year and incidence of cardiac allograft vasculopathy were similar between groups. Ten patients (11%) in Group A required recommencement of combination immunosuppression at an average of 768 +/- 772 days., Conclusions: TM is achievable in the majority of cardiac transplant recipients. Patients who tolerated reduced immunosuppression enjoyed greater survival than those treated with other regimens, without additional high-grade rejection or vasculopathy. These promising results remain to be confirmed in a prospective trial.
