Abstract: | BACKGROUND: Rejection associated with heart failure or death occurs after pediatric cardiac transplantation but has had limited analysis. METHODS: We analyzed the records of 96 consecutive pediatric cardiac transplant recipients who survived to hospital discharge. RESULTS: Eighteen patients (19%) experienced 23 episodes of heart failure or death associated with rejection. Univariate analysis demonstrated black race (p = 0.041), transplantation after 12 months of age (p = 0.032), later time after transplantation (p = 0.037), rejection episode in the first year after transplantation (p = 0.001), and history of two or more rejection episodes (p < 0.001) were significantly associated with rejection seen with heart failure. A multivariate regression analysis identified two or more rejection episodes to be the only independent risk factor for the development of rejection with heart failure (odds ratio 20; 95% confidence limits, 4-104; p < 0.0001). CONCLUSIONS: This study identified pediatric heart transplant recipients with a history of previous rejection episodes to be at a higher risk for symptomatic or fatal rejection. Further studies are needed to determine if intensification of maintenance immunosuppression, long-term rejection surveillance, or both in patients with multiple rejection episodes could reduce morbidity and mortality from rejection. |
