COVID-19 in a patient with sporadic lymphangioleiomyomatosis awaiting lung transplantation

Abstract

Coronavirus disease 2019 (COVID-19) is an emerging viral disease with a mortality that depends on the individual's condition. Underlying comorbidities are major risk factors for COVID-19-related morbidity and mortality. However, information regarding the clinical course of COVID-19 in patients with rare respiratory system diseases is lacking. Here, we present a case of severe COVID-19 in a patient with advanced sporadic lymphangioleiomyomatosis (LAM) who was awaiting lung transplantation. She experienced a marked worsening of her respiratory status despite the limited size of the infiltrations seen on chest computed tomography. She responded to treatment with dexamethasone and remdesivir, and did not require mechanical ventilation. She recovered her pre-COVID-19 respiratory function. This case illustrates that patients with severe lung parenchymal destruction due to advanced LAM are at risk of worsening hypoxemia, but may not have a bad outcome if managed appropriately. Prevention and early diagnosis of COVID-19 are crucial in patients with advanced LAM. Future studies are needed to improve understanding of the clinical features and optimal treatment of COVID-19 in patients with LAM.
