Clinical characteristics, management practices, and outcomes among lung transplant patients with COVID-19

BACKGROUND: There are limited data on management strategies and outcomes among lung transplant (LT) patients with Coronavirus disease 2019 (COVID-19). We implemented management protocols based on the best available evidence and consensus among multidisciplinary teams. The current study reports our experience and outcomes using this protocol-based management strategy. METHODS: We included single or bilateral LT patients who tested positive for SARS-CoV-2 on nasopharyngeal swab between March 1, 2020, to December 15, 2020 (n = 25; median age: 60, range 20-73 years; M: F 17:8). A group of patients with Respiratory Syncytial Virus (RSV) infection during 2016-18 were included to serve as a comparator group (n = 36). RESULTS: As compared to RSV, patients with COVID-19 were more likely to present with constitutional symptoms, spirometric decline, pulmonary opacities, new or worsening respiratory failure, and need for ventilator support. Patients with SARS-CoV-2 infection were less likely to receive a multimodality treatment strategy, and they experienced worse post-infection lung function loss, functional decline, and three-month survival. A significant proportion of patients with COVID-19 needed readmission for worsening allograft function (36.4%), and chronic kidney disease at initial presentation was associated with this complication. Lower pre-morbid FEV1 appeared to increase the risk of new or worsening respiratory failure, which was associated with worse outcomes. Overall hospital survival was 88% (n = 22). Follow-up data was available for all discharged patients (median: 43.5 days, range 15-287 days). A majority had persistent radiological opacities (19/22, 86.4%), with nearly half of the patients with available post-COVID-19 spirometry showing > 10% loss in lung function (6/13, median loss: 14.5%, range 10%-31%). CONCLUSIONS: Despite similar demographic characteristics and predispositions, LT patients with COVID-19 are sicker and experience worse outcomes as compared to RSV. Despite the availability of newer therapeutic agents, COVID-19 continues to be associated with significant morbidity and mortality. (C) 2021 International Society for Heart and Lung Transplantation.

Automated summary

This study showed that compared to patients with RSV, those with COVID-19 were more likely to present with constitutional symptoms, decline in lung function, pulmonary opacities, new or worsening respiratory failure, and need for ventilator support. Patients with SARS-CoV-2 infection were less likely to receive a multimodality treatment strategy and experienced worse post-infection outcomes, including lung function loss, functional decline, and three-month survival.
