BackgroundIn a recent preliminary study, eosinophil and basophil counts were calculated in chronic rhinosinusitis with nasal polyps (CRSwNP) using conventional histologic and immunohistochemical methods. The tissue eosinophil-to-basophil ratio differed in the CRSwNP endotypes considered.ObjectiveTo compare the blood eosinophil-to-basophil ratio (bEBR) in a large series of patients with CRSwNP with that in a control group of consecutive rhinological patients with no evidence of nasal, paranasal, or systemic inflammatory disorders.MethodsA retrospective study was performed on 334 patients with CRSwNP to compare the preoperative bEBR among different endotypes and with controls (69 cases).ResultsThe mean bEBR was significantly higher in the CRSwNP group than in the control group (P = .0006). The eosinophil and basophil counts were significantly and directly correlated in the CRSwNP cases (P = .0000). The mean bEBR was significantly higher in the sub-cohorts of CRSwNP with allergy (P = .0007), asthma (P = .0000), and aspirin-exacerbated respiratory disease (P = .0153). The mean bEBR was significantly higher in the sub-cohort with eosinophilic CRSwNP than in the sub-cohort with noneosinophilic CRSwNP (P = .0000).ConclusionThis study confirms the increasingly interesting role emerging for blood eosinophils and basophils in different CRSwNP endotypes. The bEBR seems to be a parameter worth investigating in different CRSwNP endotypes, because it is significantly higher in patients with allergy, asthma, and aspirin-exacerbated respiratory disease.
