Abstract
Peripheral blood eosinophils are now seen as an important marker in determining the leading endotype of the inflammatory response in patients with severe uncontrolled rhinosinusitis polyposa. The T2-endotype of inflammation is dominant in this group of patients, frequently associated with other T2-immunomediated diseases. In accordance with the current strategy for treating severe, uncontrolled rhinosinusitis polyposa, the absolute eosinophil count is a prerequisite for deciding on the use of genetically engineered biological therapy. However, despite the high efficacy of these treatments as demonstrated by the results of clinical studies and real-world clinical practice, transient blood eosinophilia has been reported, sometimes with the development of hypereosinophilic syndrome in individual patients receiving dupilumab treatment. This situation requires detailed monitoring of changes in the peripheral blood eosinophil count due to the potential risks of toxic effects on the epithelial cells of the respiratory tract, cardiac muscle cells, and vascular endothelium.
