Abstract
BACKGROUND: Bronchial thermoplasty (BT) is a novel bronchoscopic intervention for severe persistent asthma. An increase in transient respiratory adverse events associated with BT were noted over the treatment periods, however, these events appear sporadic and should not always recur in a single individual and BT-related pneumonia has rarely been reported. CASE PRESENTATION: We present a case of uncontrolled severe asthma who developed puzzling pneumonia sequentially after each session of BT procedures. After each operation of three sequential BT procedures, she developed cough and purulent expectoration when her chest radiology showed new infiltrates right in the treatment regions. After empirical use of antibacterial agents plus physiotherapy and postural sputum drainage, her symptoms vanished and chest imaging resumed normal. CONCLUSION: The originality of our case report is related to the recurrence of pneumonia after three sequential BT procedures. To date, similar report has not been available in the literature. We hope to prompt alerts for post-BT respiratory infections, although most of them, along with other adverse events, are mild and tractable.
