Abstract

Abstract: Background: Despite successes in lung transplantation, with infection as the leading cause of death in the first year following lung transplantation, there remains a lag in survival compared with other solid organ transplants. Infections that occur early after transplantation may impact short- and long-term outcomes in pediatric lung transplant recipients (LTRs). Methods: We performed a retrospective review of pediatric LTRs at a large quaternary-care hospital from January 2009 to March 2016 to evaluate both epidemiologic features of infection in the first 30 days post-transplantation and mortality outcomes. The 30 days were divided into early (0–7 days) and late (8–30 days) periods. Results: Among the 98 LTRs, there were 51 episodes of infections. Cystic fibrosis (CF) was associated with early bacterial infections ( P = .004) while non-CF was associated with late viral ( P = .02) infections. Infection after transplantation was associated with worse survival by Kaplan-Meier analysis ( P value log rank test = .007). Viral infection in the late period was significantly associated with 3-year mortality after multivariable analysis ( P = .02). Conclusions: Infections in pediatric LTRs were frequent in the first 30 days after transplant, despite perioperative antimicrobial coverage. The association of 3-year mortality with late viral infections suggests a possible important role in post-transplant lung physiology and graft function. Understanding the epidemiology of early post-lung transplant infections can help guide post-operative management and interventions to reduce their incidence and the early- and long-term impact in this population. Abstract : In our evaluation of the epidemiologic features of infections in the first 30 days following pediatric lung transplantation, we found a high incidence of infection despite targeted antimicrobial therapy, with viral infections on days 8 through 30 associated with 3-year mortality.
