Adenosine metabolic activity in BALF from preschool children with CF was assessed as the ability to generate hypoxanthine (Hyp) from exogenously added adenosine (Ado). Samples with no significant bronchitis (<40% neutrophils) had no significant activity, whereas activity was readily detected in samples with bronchitis (>60% neutrophils). BALF from clinically stable preschoolers with bronchiectasis (BE) on chest CT showed moderate levels of adenosine metabolic activity. N=3–4 per group. * = p<0.01 by Mann-Whitney, with significant post tests for bronchitis and BE groups relative to no bronchitis.
