Can we apply biomarkers in the management of non-steroidal anti-inflammatory drug exacerbated respiratory disease?

Le résumé fourni par la source

Non-steroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (NERD) is characterized by adult-onset asthma, chronic rhinosinusitis with nasal polyps (CRSwNPs), and aspirin/NSAID hypersensitivity, presenting recurrent asthma exacerbation and poor clinical outcomes. Patients with NERD have heterogeneous clinical phenotypes/endotypes, and the management of NERD remains challenging. Dysregulation of arachidonic acid (AA) metabolism and persistent eosinophilic airway inflammation are the major pathogenic mechanisms in the upper and lower airways of NERD. To date, increased levels of urinary leukotriene E4 (uLTE4) [a terminal metabolite of the lipoxygenase (LOX) pathway] have been the most relevant biomarker for NERD. It is demonstrated that mast cells, platelets, and epithelial cells can amplify upper and lower airway inflammation in NERD, and several potential biomarkers based on these complicated and heterogeneous mechanisms have been suggested. This review summarizes potential biomarkers for application in the management of NERD.
