RESUMEN
BACKGROUND: Studies evaluating the prevalence and impact of recurrent rejection (RR) in pediatric heart transplant (HT) are sparse. OBJECTIVES: The purpose of this study was to describe prevalence and impact of RR on cardiac allograft vasculopathy (CAV) and graft loss after pediatric HT. METHODS: Data on HT from January 1, 2000, to June 30, 2020, in the Pediatric Heart Transplant Society database were included. Freedom from RR (≥2 rejection episodes) was compared by era (early: 2000-2009; current: 2010-2020). Outcomes for children experiencing RR were compared with those experiencing 0 or 1 rejection episodes and by type of RR (antibody-mediated rejection [AMR], acute cellular rejection [ACR], mixed [ACR/AMR]). RESULTS: Of 6,342 HT recipients, 1,035 (17%) experienced RR. In the current era, pediatric HT recipients were less likely to experience RR (P < 0.001). Freedom from CAV was similar for those experiencing RR to those experiencing 0 or 1 episode (96.6% vs 95.3% vs 96.6%); and similar regardless of the type of RR (AMR, ACR, or mixed) (65.5% vs 82.9% vs 100%) (P > 0.05). Freedom from graft loss was significantly lower for those experiencing RR to those experiencing 0 or 1 episode (56.3% vs 72.3% vs 82.3%) and lower for those experiencing recurrent mixed rejection or recurrent AMR compared with those experiencing recurrent ACR (65.3% vs 50% vs 81.8%). Black children experiencing RR subsequently had lower freedom from CAV and graft loss than White children (P < 0.05 for all). CONCLUSIONS: Although prevalence of RR has decreased, children experiencing RR are at greatly increased risk for losing their graft, particularly those who have recurrent mixed or antibody-mediated rejection.
RESUMEN
The congenital heart care community faces a myriad of public health issues that act as barriers toward optimum patient outcomes. In this article, we attempt to define advocacy and policy initiatives meant to spotlight and potentially address these challenges. Issues are organized into the following 3 key facets of our community: patient population, health care delivery, and workforce. We discuss the social determinants of health and health care disparities that affect patients in the community that require the attention of policy makers. Furthermore, we highlight the many needs of the growing adults with congenital heart disease and those with comorbidities, highlighting concerns regarding the inequities in access to cardiac care and the need for multidisciplinary care. We also recognize the problems of transparency in outcomes reporting and the promising application of telehealth. Finally, we highlight the training of providers, measures of productivity, diversity in the workforce, and the importance of patient-family centered organizations in advocating for patients. Although all of these issues remain relevant to many subspecialties in medicine, this article attempts to illustrate the unique needs of this population and highlight ways in which to work together to address important opportunities for change in the cardiac care community and beyond. This article provides a framework for policy and advocacy efforts for the next decade.
