BACKGROUND: Non-cystic fibrosis (CF) bronchiectasis is characterised by chronic
airway infection and neutrophilic inflammation, which we hypothesised would be
associated with Th17 pathway activation. METHODS: Th17 pathway cytokines were
quantified in bronchoalveolar lavage fluid (BALF), and gene expression of IL-17A,
IL-1?, IL-8 and IL-23 determined from endobronchial biopsies (EBx) in 41 stable
bronchiectasis subjects and 20 healthy controls. Relationships between IL-17A
levels and infection status, important clinical measures and subsequent
Pseudomonas aeruginosa infection were determined. RESULTS: BALF levels of all
Th17 cytokines (median (IQR) pg/mL) were significantly higher in bronchiectasis
than control subjects, including IL-17A (1.73 (1.19, 3.23) vs. 0.27 (0.24, 0.35),
95% CI 1.05 to 2.21, p<0.0001) and IL-23 (9.48 (4.79, 15.75) vs. 0.70 (0.43,
1.79), 95% CI 4.68 to 11.21, p<0.0001). However, BALF IL-17A levels were not
associated with clinical measures or airway microbiology, nor predictive of
subsequent P. aeruginosa infection. Furthermore, gene expression of IL-17A in
bronchiectasis EBx did not differ from control. In contrast, gene expression
(relative to medians of controls) in bronchiectasis EBx was significantly higher
than control for IL1? (4.12 (1.24, 8.05) vs 1 (0.13, 2.95), 95% CI 0.05 to 4.07,
p = 0.04) and IL-8 (3.75 (1.64, 11.27) vs 1 (0.54, 3.89), 95% CI 0.32 to 4.87, p
= 0.02) and BALF IL-8 and IL-1? levels showed significant relationships with
clinical measures and airway microbiology. P. aeruginosa infection was associated
with increased levels of IL-8 while Haemophilus influenzae was associated with
increased IL-1?. CONCLUSIONS AND CLINICAL RELEVANCE: Established adult non-CF
bronchiectasis is characterised by luminal Th17 pathway activation, however this
pathway may be relatively less important than activation of non-antigen-specific
innate neutrophilic immunity.
