Background: The largest age group among children and adolescents referred for lung transplantation for cystic fibrosis (CF) have been those who in the pubertal or post pubertal age range. However, over 100 younger patients with CF have undergone lung transplantation over the last three decades in the USA. Methods: 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. Results: Notable findings were a high prevalence of methicillin-resistant Staphylococcus aureus, a high prevalence of diabetes mellitus and an impressive prevalence of consolidated lobar or whole lung disease. Post-transplant outcomes, however, were comparable to those older than 10 years of age in our center. Conclusions: 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 and potentially more important for effective intervention in order to extend life.
