Cystic fibrosis lung transplant recipients 10 years of age or younger: Predisposing factors for end-stage disease.

Abstract

The largest age group among children and adolescents referred for lung transplantation for cystic fibrosis (CF) have been those in the pubertal or postpubertal age range. However, over 100 younger patients with CF have undergone lung transplantation over the last three decades in the United States. We performed a retrospective review of our experience with 18 children with CF who underwent lung transplantation in our center before the age of 11 years and compared them to our older CF lung transplant recipients and our larger CF Center population. The transplant population was demographically distinct from our CF center in terms of ethnicity, country of origin, and insurance status. Other notable findings were a high prevalence of methicillin-resistant Staphylococcus aureus, a high prevalence of CF-related diabetes mellitus, and a high prevalence of consolidated lobar or whole lung disease. Posttransplant outcomes were comparable to those older than 10 years of age in our center until 5 years after transplant after which the younger cohort showed a superior enduring survival. In an era of increasingly effective medications modifying the natural history of CF, identification of risk factors for early severe lung disease in CF remains relevant to permit interventions to prevent or postpone the time of future lung transplantation.
