RT Journal Article SR Electronic T1 New-onset asthma in a bilateral lung transplant patient JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e231654 DO 10.1136/bcr-2019-231654 VO 12 IS 11 A1 Daniel Benjamin Fyenbo A1 Kristine Bruun Degn A1 Johannes Martin Schmid A1 Elisabeth Bendstrup YR 2019 UL http://casereports.bmj.com/content/12/11/e231654.abstract AB We present a case of new-onset asthma in a 35-year-old man who had undergone bilateral lung transplantation 11 years before due to idiopathic bronchiectasis and pulmonary hypertension. He presented with recurrent episodes of breathlessness, wheezing and coughing. Spirometry demonstrated severe airway obstruction. After treatment with systemic and inhaled corticosteroids and long-acting bronchodilators as well as short-acting beta-agonists as needed, his symptoms resolved and his spirometry normalised. A bronchial mannitol challenge test showed significant airway hyperresponsiveness and is thus consistent for a diagnosis of asthma. To our best knowledge, this is the first case of late new-onset asthma in a lung transplant recipient.
