Moreover, a significant difference in the evaluation of asthma control was found between ACT and GINA assessment of symptom control (p<0.05). 0.05). Responses to ACT single items showed a statistically significant difference between patients with lower and higher education levels in ACT items n°3 and 5, (p less then 0.05), with lower education levels influencing patients symptom perception and disease control. Moreover, a significant difference in the evaluation of asthma control was found between ACT and GINA assessment of symptom control (p less then 0.05). Autoantibodies to bactericidal/permeability-increasing protein (BPI), BPI-ANCA, are often present in serum of patients with cystic fibrosis (CF), and correlate to airway colonization with Pseudomonas aeruginosa. The aim of the study was to investigate if BPI-ANCA IgA is also present in the airways of CF patients, and if its presence correlates with neutrophil counts, platelets, and P. aeruginosa DNA in sputum. BPI-ANCA IgA was quantified in serum and sputum samples from adult CF patients (n=45) by ELISA. Sputum neutrophil counts, platelets, and platelet-neutrophil complexes were assessed by flow cytometry, and P. aeruginosa DNA was analysed with RT-PCR. Serum BPI-ANCA IgA was present in 44% of the study participants, and this group also had significantly enhanced BPI-ANCA levels in sputum compared to serum negative patients. Sputum levels of BPI-ANCA IgA correlated with P. aeruginosa DNA (r=0.63, p=0.0003) and platelet counts in sputum (r=0.60, p=0.0002). BPI-ANCA is expressed in the airways of CF patients and correlates with P. aeruginosa load and platelet counts, suggesting a link to airway inflammation and mucosal immunity.
