Snippet: Indications of airway inflammation include changes in cellular profile and the presence of pro-inflammatory cytokines in the BAL or sputum. In adults and children with suppurative lung disease, airway inflammation is characterised by elevated levels of neutrophils, IL-1β, IL-6 and IL-8 [11, 19, 20] . Thus, we chose to focus on these cytokines. We found that, in our cohort of young children with CSLD, IL-1β, IL-6, IL-8 as well as IP-10 and LL-37.....
Document: Indications of airway inflammation include changes in cellular profile and the presence of pro-inflammatory cytokines in the BAL or sputum. In adults and children with suppurative lung disease, airway inflammation is characterised by elevated levels of neutrophils, IL-1β, IL-6 and IL-8 [11, 19, 20] . Thus, we chose to focus on these cytokines. We found that, in our cohort of young children with CSLD, IL-1β, IL-6, IL-8 as well as IP-10 and LL-37 in the BAL were significantly correlated with BAL neutrophils. These markers of inflammation also negatively correlated with systemic NTHi-specific IFN-γ production on univariate analysis. However, on multivariate regression, only IL-6 and IL-1β were significantly and independently associated with NTHi-specific IFN-γ production.
