U-BIOPRED is a European Union consortium of 20 academic institutions, 11 pharmaceutical companies and six patient organisations with the objective of improving the understanding of asthma disease mechanisms using a systems biology approach.This cross-sectional assessment of adults with severe asthma, mild/moderate asthma and healthy controls from 11 European countries consisted of analyses of patient-reported outcomes, lung function, blood and airway inflammatory measurements.Patients with severe asthma (nonsmokers, n=311; smokers/ex-smokers, n=110) had more symptoms and exacerbations compared to patients with mild/moderate disease (n=88) (2.5 exacerbations versus 0.4 in the preceding 12 months; p<0.001), with worse quality of life, and higher levels of anxiety and depression. They also had a higher incidence of nasal polyps and gastro-oesophageal reflux with lower lung function. Sputum eosinophil count was higher in severe asthma compared to mild/moderate asthma (median count 2.99% versus 1.05%; p=0.004) despite treatment with higher doses of inhaled and/or oral corticosteroids.Consistent with other severe asthma cohorts, U-BIOPRED is characterised by poor symptom control, increased comorbidity and airway inflammation, despite high levels of treatment. It is well suited to identify asthma phenotypes using the array of "omic" datasets that are at the core of this systems medicine approach. @ERSpublications Severe asthma results in more airway inflammation, worse symptoms and lower lung function, despite increased therapy http://ow.ly/QznR3

The Indacaterol: Switching Non-exacerbating Patients with Moderate COPD From Salmeterol/Fluticasone to Indacaterol (INSTEAD) study investigated the effect of switching patients at low risk of chronic obstructive pulmonary disease (COPD) exacerbations from salmeterol/fluticasone (SFC; inhaled corticosteroid (ICS) regimen) to indacaterol monotherapy (non-ICS regimen).This 26-week, double-blind, double-dummy, parallel-group, phase IV study, randomised 581 patients with moderate COPD to indacaterol 150 mg once daily or SFC 50/500 mg twice daily. Patients had been receiving SFC 50/500 mg for o3 months, with no COPD exacerbations for more than a year before the study (patients for whom ICS is not recommended). The primary objective was to demonstrate noninferiority of indacaterol to SFC, measured by trough forced expiratory volume in 1 second (FEV1) after 12 weeks (non-inferiority margin of 0.06 L).The primary objective was met, with a mean treatment difference of 9 mL (95% CI -45-26 mL). There were no significant differences between treatments in terms of breathlessness (transition dyspnoea index) or health status (Saint George's Respiratory Questionnaire) at weeks 12 or 26, or rescue medication use or COPD exacerbation rates over 26 weeks. Safety profiles of both treatments were as expected.This study demonstrated that patients with moderate COPD and no exacerbations in the previous year can be switched from SFC to indacaterol 150 mg with no efficacy loss. @ERSpublications Moderate COPD patients can switch from salmeterol/fluticasone to indacaterol with no efficacy loss

The increased IL-6 levels in exhaled breath condensate may reflect airway inflammation in patients with COPD.

Omalizumab is a humanized murine monoclonal antibody directed toward a portion of the IgE indicated in Europe for the treatment of severe persistent allergic asthma, inadequately controlled despite high-dose of ICS (mean BDP equivalent dose of inhaled corticosteroid 2224.68microg/die) in association with long-acting beta(2) agonists. Our aim was to describe the experience, efficacy and safety in a cohort of Italian patients treated with omalizumab in a real-life clinical setting. One hundred and forty two patients from 13 Italian Centers were observed and analysed. The dosage of omalizumab was established according to the labelling indication, with a median dose of IgE of 297.38IU/ml or kU/l. During the previous year, all patients experienced frequent exacerbations (mean=4.87), emergency visits (mean=4.45) and hospitalisation (mean=1.53). Following treatment with omalizumab, the annual rate of exacerbations, emergency visits and hospitalisation decreased by 79%, 88% and 95%, respectively. The proportion of patients without exacerbation, not needing emergency visits and hospitalization increased by 610%, 154% and 28%, respectively. The response to omalizumab measured with the GETE (global evaluation of treatment effectiveness) scale rated as good to excellent in 77% of patients. Overall, 9.6% (n=9) of the patients experienced one single adverse effect. Only one patient reported a serious adverse event (local reaction at the site of injection) leading to interruption of treatment. The observed reduction of asthma-related events in particularly poorly controlled patients in this Italian real-life setting is consistent with the results of other observational studies.
