Abstract
OBJECTIVE: Most countries worldwide have transplant registries for patients with end-stage lung diseases (ESLD) requiring lung transplantation. There is no such lung transplant registry in India. Herein, we describe the demographic profile and clinical outcomes among patients referred for lung transplantation at a tertiary care center in North India. MATERIALS AND METHODS: This was a prospective, observational study of consecutive patients with chronic respiratory diseases who were referred for lung transplantation between July 2013 and December 2016. Patients were evaluated using standard criteria for listing for lung transplantation. RESULTS: Of the 176 patients assessed for lung transplantation, 167 were included in the study. The mean (standard deviation [SD]) age of the study population (52.1% females) was 53.2 (14.7) years. Interstitial lung disease (ILD, 46.7%), chronic obstructive pulmonary disease (COPD, 25.7%), and bronchiectasis (10.2%) were the most common diseases in this population. The median (interquartile range, IQR) survival was worst for patients with bronchiolitis (78.5 [9-208] days) and idiopathic pulmonary fibrosis (IPF, 93.5 [19-239] days) and best for patients with idiopathic pulmonary arterial hypertension (757 [340-876] days) and COPD (578 [184-763] days). Only 13% of the patients expressed willingness for lung transplantation. Patients willing for transplantation died earlier than those unwilling (median [IQR], 102 [36-224] days vs. 310 [41-713] days, P < 0.001). CONCLUSION: ILD was the most common cause of ESLD in patients referred for lung transplantation. The waitlist mortality was highest for patients with bronchiolitis and IPF. Despite having ESLD, very few patients were willing for lung transplantation. Patients willing for lung transplantation died earlier than those who were unwilling.
