This study reveals two distinct patient subgroups in severe asthma, showing different molecular responses to dupilumab treatment. These findings support personalized medicine approaches for asthma patients receiving biologic therapies.

Area of Science:

  • Immunology
  • Genomics
  • Precision Medicine

Background:

  • Asthma is a complex inflammatory condition often co-occurring with chronic rhinosinusitis with nasal polyps (CRSwNP).
  • Biologic therapies like dupilumab are effective, but individual responses vary due to poorly understood molecular mechanisms.

Purpose of the Study:

  • To identify transcriptomic patterns differentiating asthma patients from controls.
  • To analyze molecular changes induced by dupilumab treatment in severe asthma.
  • To explore distinct patient endotypes and predict treatment response.

Main Methods:

  • Whole-blood RNA sequencing (RNA-seq) on 66 samples from severe asthma patients and controls.
  • Differential gene expression analysis and quantitative PCR (qPCR) validation.

  • Unsupervised machine learning to identify patient subgroups and treatment response patterns.

    • Main Results:

    • Identified 1124 differentially expressed genes (DEGs) between asthmatic patients and controls.
    • Discovered two distinct patient subgroups (G1, G2) with divergent transcriptomic responses to dupilumab.
    • Found baseline DIXDC1 expression predicts non-response in CRSwNP patients.

    Conclusions:

    • Unsupervised machine learning on transcriptomic data reveals two distinct asthma endotypes with differential dupilumab response.
    • This highlights the potential for a precision medicine strategy in severe asthma management.
    • Identified key genes and biomarkers for disease characterization and treatment prediction.
