BackgroundIdiopathic pulmonary fibrosis (IPF) is a rapidly progressive interstitial lung disease with high mortality. Lung transplant remains a cornerstone of treatment despite the advent of antifibrotic therapy. In light of the increasing number of patients on antifibrotic therapy prior to lung transplantation it is paramount to demonstrate these medications do not augment postoperative complications following transplant.Research QuestionDoes antifibrotic therapy increase perioperative complications and mortality in lung transplant recipients?Study Design And MethodsWe conducted a retrospective chart review of all patients actively listed for lung transplant at Temple University Hospital from June 2014 to April 2017 with a listing diagnosis of IPF. Subjects who received treatment with antifibrotic therapy (either pirfenidone or nintedanib) up until the time of lung transplantation were compared to subjects not on therapy. Data was collected regarding baseline demographics, pulmonary function tests, IPF exacerbations, perioperative bleeding and cardiac events, and outcomes in the postoperative period.ResultsA total of 94 subjects were included in the study: 42 subjects on antifibrotic therapy (28 pirfenidone, 14 nintedanib) and 52 subjects not on therapy in the pre-transplant period. Baseline characteristics were similar between study groups. Subjects treated with antifibrotic therapy pre-transplant were noted to have less FVC decline, fewer hospitalizations, and greater weight loss while on the transplant waiting list. No difference in post-transplant airway anastomosis complications, bleeding or mortality was observed between study groups.InterpretationSubjects with IPF on antifibrotic therapy prior to lung transplantation had better preservation of lung function in the pre-transplant period, and similar outcomes in the postoperative period compared to those not on antifibrotic therapy before lung transplant.Copyright © 2021.
