Effect of antifibrotic agents on postoperative complications after lung transplantation for idiopathic pulmonary fibrosis

BackgroundAntifibrotic agents (AFAs) are now standard-of-care for idiopathic pulmonary fibrosis (IPF). Concerns have arisen about the safety of these drugs in patients undergoing lung transplantation (LTx).MethodsWe performed a multi-centre, nationwide, retrospective, observational study of French IPF patients undergoing LTx between 2011 and 2018 to determine whether maintaining AFAs in the peri-operative period leads to increased bronchial anastomoses issues, delay in skin healing and haemorrhagic complications. We compared the incidence of post-operative complications and the survival of patients according to AFA exposure.ResultsAmong 205 patients who underwent LTx for IPF during the study period, 58 (28%) had received AFAs within 4 weeks before LTx (AFA group): pirfenidone in 37 (18.0%) and nintedanib in 21 (10.2%). The median duration of AFA treatment before LTx was 13.8 (5.6-24) months. The AFA and control groups did not significantly differ in airway, bleeding or skin healing complications (p = 0.91, p = 0.12 and p = 0.70, respectively). Primary graft dysfunction was less frequent in the AFA than control group (26% vs. 43%, p = 0.02), and the 90-day mortality was lower (7% vs. 18%, p = 0.046).ConclusionsAFA therapy did not increase airway, bleeding or wound post-operative complications after LTx and could be associated with reduced rates of primary graft dysfunction and 90-day mortality. This multi-centre nationwide, retrospective study including 58 patients receiving antifibrotic agents before lung transplantation for idiopathic pulmonary fibrosis shows that their use did not increase airway, bleeding or wound post-operative complications and could be associated with reduced rates of primary graft dysfunction and 90-day mortality.image

Automated summary

A multi-center nationwide retrospective study in France shows that continuing antifibrotic agents (AFAs) treatment before lung transplantation (LTx) does not increase the risk of post-operative airway, bleeding, or wound complications. In fact, it may be associated with reduced rates of primary graft dysfunction and 90-day mortality.
