Analysis of Intrahospital Mortality in Patients With Lung Transplant Due to Diffuse Parenchymal Lung Disease

Trends and Outcomes in Lung Transplantation in Patients with and without Idiopathic Pulmonary Fibrosis in Spain during the Period 2016-2020

(1) Background: This paper aims to assess temporal trends (2016-2020) in incidence, patient's characteristics, complications, length of hospital stay (LOHS) and in-hospital mortality (IHM) among patients with and without idiopathic pulmonary fibrosis (IPF) undergoing lung transplantation (LTx). We also analyse the effect of the COVID-19 pandemic on LTx in these populations. (2) Methods: A retrospective, population-based observational study was conducted using the Spanish National Hospital Discharge Database. Multivariable adjustment was conducted with logistic regression to analyse the IHM. (3) Results: We identified 1777 admissions for LTx during the study period, of which 573 (32.2%) were performed in patients with IPF. The number of hospital admissions for LTx rose from 2016 to 2020, both in patients with and without IPF, but a marked reduction was observed from year 2019 to year 2020. Over time, the proportion of single LTx decreased and bilateral LTx increased significantly in both groups. The incidence of LTx complications increased significantly over time along with the increase in the incidence of IPF. No significant differences in the incidence of complications or in the IHM between patients with and without IPF were found. Suffering any complication of the LTx and pulmonary hypertension were conditions positively associated with IHM in patients with and without IPF. The IHM remained stable from 2016 to 2020 in both study populations and was not affected by the COVID pandemic. (4) Conclusions: Patients with IPF account for almost a third of all lung transplants. The number of LTx increased over time in patients with and without IPF, but a marked reduction was observed from 2019 to 2020. Although the proportion of LTx complications increased significantly over time in both groups, the IHM did not change. IPF was not associated with increased complications or IHM after LTx.

Advances in lung transplantation for interstitial lung diseases

PURPOSE OF REVIEW

Lung transplantation (LTx) is increasingly used as ultimate treatment modality in end-stage interstitial lung diseases (ILDs). This review aims to give an overview of the latest evolutions in this field.

RECENT FINDINGS

In the last two years, important new findings regarding LTx outcomes in specific ILD entities have been reported. More data are available on optimization of pre-LTx management of ILD patients especially with regard to pretransplant antifibrotic treatment.

SUMMARY

LTx is the only treatment option with curative intent for ILDs and is increasingly used for this indication. Several studies have now reported adequate outcomes in different ILD entities, although outcome is shown to be affected by underlying telomeropathies. As new studies could not replicate inferior survival with single compared with double LTx, both options remain acceptable. ILD specialists can beneficially impact on post-LTx outcome by optimizing pre-LTx management: corticosteroids should be avoided, antifibrotics should be initiated whenever possible and BMI and nutritional status optimized, rehabilitation and depression-screening strategies should be implemented in all LTx candidates, as these interventions may all improve postlung transplant survival.
