Background and objective: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) due to Pseudomonas aeruginosa (PA) are associated with worse outcomes. PA antibiotic resistance is important to determine treatment and may influence clinical outcomes. The aim was to study clinical characteristics and outcomes in patients with AECOPD associated with PA based on their antibiotic resistance. Methods: This was a prospective observational study including all patients with AECOPD and positive PA sputum culture admitted in a respiratory ward in a tertiary hospital in Barcelona during 2013-2014. PA was defined as resistant (PA-R) when the antibiogram showed ≥1 resistance. Results: Four hundred one patients with AECOPD were evaluated. Of them, 54 (13%) had a positive PA sputum culture. Eighty-two per cent were men, median age was 77 (SD 7) years old and FEV 1 was less than 36% (SD 17) of predicted value. PA-R was isolated in 35 patients (66%), and PA-sensitive (PA-S) was isolated in 18 (34%) patients. No differences were found in demographics, lung function and comorbidities among groups. PA-R patients were more likely exposed to prior oral corticosteroids (77% vs 44%, P = 0.03) and antibiotics (77% vs 31%, P = 0.01), respectively. AECOPD patients associated with PA-S were more likely to die at 30 days (odds ratio 13.53, 95% confidence interval: 1.14-69.56, P = 0.03) and 90 days (odds ratio 7.09, 95% confidence interval: 1.33-37.89, P = 0.02), respectively. Conclusion: Pseudomonas aeruginosa-resistant affects patients with severe AECOPD and previous use of corticosteroids and antibiotics. The presence of PA-S is associated with higher mortality. These results may suggest increased virulence in PA-S strains causing acute infections.

We assessed the effectiveness of an asthma educational programme based on a repeated short intervention (AEP-RSI) to improve asthma control (symptom control and future risk) and quality of life.A total of 230 adults with mild-to-moderate persistent uncontrolled asthma participated in a 1-year cluster randomised controlled multicentre study. The AEP-RSI was given in four face-to-face sessions at 3-month intervals, and included administration of a written personalised action plan and training on inhaler technique. Centres were randomised to the AEP-RSI (intervention) group or usual clinical practice group. Specialised centres using a standard educational programme were the gold standard group. A significant improvement in the Asthma Control Test score was observed in all three groups ( p<0.001), but improvements were higher in the intervention and gold standard groups than in the usual clinical practice group (p=0.042), which also showed fewer exacerbations (mean±SD; 1.20±2.02 and 0.56±1.5 versus 2.04±2.72, respectively) and greater increases in the Mini Asthma Quality of Life Questionnaire scores (0.95±1.04 and 0.89±0.84 versus 0.52±0.97, respectively).The AEP-RSI was effective in improving asthma symptom control, future risk and quality of life. @ERSpublications An educational programme based on a repeated short intervention for asthma is effective and easily to use in practice

Background: Pseudomonas aeruginosa (PA) is a common microorganism related to severe exacerbations in Chronic Obstructive Pulmonary Disease (COPD). However, their role in COPD patients with frequent hospitalized exacerbations (FHE) is not well described. Objectives: We aimed to determine prevalence, risk factors, susceptibility patterns and impact on outcomes of PA in COPD patients with FHE. Methods: Prospective observational multicentre study that included COPD patients with FHE. The cohort was stratified in 2 groups according to the presence or absence of PA isolation in sputum. Patients were followed up for 12 months. Results: We enrolled 207 COPD patients with FHE. In 119 patients (57%), a valid sputum culture was collected. Of them, PA was isolated in 21 patients (18%). The risk factors associated with PA were prior use of systemic corticosteroids (OR 3.3, 95% CI 1.2–9.7, p = 0.01) and prior isolation of PA (OR 4.36, 95% CI 1.4–13.4, p < 0.01). Patients with PA had an increased risk of having ≥3 readmissions (OR 4.1, 95% CI 1.3–12.8, p = 0.01) and higher PA isolation rate (OR 7.7, 95% CI 2.4–24.6, p < 0.001) during the follow-up period. In 14 patients (67%), PA was resistant to at least one antibiotic tested. PA persisted in the sputum in 70% of patients. Conclusions: The presence of PA was related to 3 or more readmissions during the 1-year follow-up and PA persisted in the sputum despite an appropriate antibiotic treatment. This finding suggested an important role of PA in the course of the disease of COPD patients with FHE.
