Cluster analysis of nasal cytokines during rhinovirus infection identifies different immunophenotypes in both children and adults with allergic asthma.

ABSTRACT:

Background

Infection with rhinovirus (RV) is a major risk factor for disease exacerbations in patients with allergic asthma. This study analysed a broad set of cytokines in the noses of children and adults with asthma during RV infection in order to identify immunophenotypes that may link to virus-induced episodes.

Methods

Nasal wash specimens were analysed in children (n = 279 [healthy, n = 125; stable asthma, n = 64; wheeze, n = 90], ages 2-12) who presented to a hospital emergency department, and in adults (n = 44 [healthy, n = 13; asthma, n = 31], ages 18-38) who were experimentally infected with RV, including a subset who received anti-IgE. Cytokines were measured by multiplex bead assay and data analysed by univariate and multivariate methods to test relationships to v
