Blood Eosinophilic and Basophilic Trends in Recurring and Non-Recurring Eosinophilic Rhinosinusitis With Nasal Polyps.

In eCRSwNP, the statistical analysis of repeated quantitative laboratory data can shed light on the evolution of a patient's systemic inflammatory picture in response to previous treatments, and above all to long-term therapies. Long-term monitoring of blood eosinophil and basophil levels could be of significant value when monoclonal antibodies that inhibit IL signaling will widely enter in clinical practice for eCRSwNP treatment to follow the effectiveness of therapy over time.
