## TL;DR

This study explores gene and pathway changes in patients with chronic sinusitis who received dupilumab, identifying potential markers for disease severity.

## Contribution

The study identifies specific genes and pathways linked to dupilumab treatment in surgically refractory chronic rhinosinusitis with nasal polyps.

## Key findings

- The CLC gene and eicosanoid pathways are differentially expressed in patients treated with dupilumab.
- Periostin and osteopontin-associated pathways are associated with dupilumab use in CRSwNP.
- These findings may help in early stratification of disease severity in CRSwNP patients.

## Abstract

An untargeted transcriptomic analysis provided exploratory insight into key genes and pathways that can be used to help identify patients at risk for surgically refractory chronic rhinosinusitis with nasal polyps (CRSwNP).
The Charcot–Leyden crystal gene, periostin and osteopontin‐associated pathways, eicosanoid synthesis pathway, and prostaglandin/leukotriene metabolism pathway, among others, are associated with dupilumab prescription for surgically refractory chronic rhinosinusitis and may support early stratification of disease severity in CRSwNP patients.
