Reduced infection in cardiac transplant recipients

Despite the introduction of cyclosporine immunosuppression, infectious morbidity and mortality in cardiac transplant recipients has remained high. To decrease infectious complications, lower doses of cyclosporine and oral prednisone than previously reported were used for maintenance immunosuppression in 22 operative survivors of orthotopic cardiac transplantation. Twelve infections occurred in 10 patients followed 8 +/- 5 months. Fifty-five percent of patients had no infectious complications. There were no deaths. Seven infections required hospitalization for a mean of 12 days. Infection rate per patient for the first 3 months after transplantation was 0.23 compared with a range of 0.82 to 1.06 in series previously reported in which higher doses of steroids were used. Lowered doses of steroid can be used for maintenance immunosuppression and treatment of rejection with acceptable short-term results. With such a protocol, a low incidence of controllable infectious complications with no deaths has been observed.
