Objective To analyze the correlation between the lung allocation score (LAS) and the risk of early death and complications in patients with idiopathic pulmonary fibrosis (IPF) after lung transplantation. Methods Clinical data of 275 patients with IPF were retrospectively analyzed. The correlation between LAS and the risk of early death in IPF patients after lung transplantation and the correlation between LAS and complications at postoperative 1 year was assessed by univariate and multivariate Cox regression analyses. Results Among 275 recipients, 62, 83, 95 and 108 cases died within postoperative 30, 90, 180 and 365 d, respectively. LAS was correlated with 30-, 90-, 180- and 365-d fatality of IPF patients (all P<0.05), whereas it was not correlated with the incidence of primary graft dysfunction (PGD) and acute kidney injury (AKI) at 365 d after lung transplantation (both P>0.05). Conclusions LAS is correlated with the risk of early death of IPF patients after lung transplantation. While, it is not correlated the incidence of PGD and AKI early after lung transplantation. Special attention should be paid to the effect of comprehensive factors upon PGD and AKI.
