Lin et al studied 61 patients with CRSwNP and found that phospho-janus kinase 2 (p-JAK2), IL-5, IL-6, and granulocyte-colony stimulating factor (G-CSF) were correlated with LMK-CT and SNOT-22 scores.57 Patients were categorized into “mild” and “severe” CRS based on Lund–Kennedy score alone, and data on patients with CRSsNP was limited. Here, JAK2 is linked to congenital rubella syndrome.
