Eosinophilic or not eosinophilic: dupilumab seems to work
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a type 2 inflammation with interleukin (IL)-4, IL-13, and IL-5. Tissue eosinophilia in nasal polyps dramatically increased over a 10-20-year period. Classification of the severity of eosinophil status is expected to lead to...
Biologicals for severe chronic rhinosinusitis with nasal polyps. Any use?
Recent advances and knowledge of inflammatory endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP) led to introduction of biological agents such as monoclonal antibodies targeting IgE (omalizumab) and Interleukins (ILs) such as IL4R alpha (dupilumab) and IL5. The European Academy...
COVID-19 in patients with chronic rhinosinusitis with polyps. Are they at risk?
COVID-19 entry factors are highly present in nasal epithelial cells. These factors include ACE2 and TMPRSS2. Their presence in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) was not investigated before. Authors investigated expression of ACE2 and TMPRSS2 in two...
