Peripheral blood eosinophil counts and bronchial responsiveness.

Abstract

Bronchial responsiveness (histamine PC20) and peripheral blood eosinophil counts were measured in 23 asthmatic subjects, of whom 14 were atopic and nine non-atopic. In the group as a whole there was an inverse correlation between baseline eosinophil count and histamine PC20 (r = -0.71; p less than 0.001). For atopic subjects a relationship between eosinophil count and histamine PC20 was observed (r = -0.74; p less than 0.01), but there was no correlation between eosinophil count and baseline FEV1 or baseline FEV1 and histamine PC20. For the non-atopic subjects a similar relationship between eosinophil count and histamine PC20 was seen (r = -0.68; p less than 0.05) and a less significant inverse correlation between baseline eosinophil count and baseline FEV1 (r = -0.65; p less than 0.05). These results show a relationship between eosinophil count and non-specific bronchial responsiveness in both atopic and non-atopic asthma.
