Efficacy and safety of an anti-IL-13 mAb in patients with severe asthma: a randomized trial.

Background: Approximately 5% to 10% of asthmatic patients achieve incomplete symptom control on current therapies. The association of IL-13 with asthma pathology and reduced corticosteroid sensitivity suggests a potential benefit of anti-IL-13 therapy in refractory asthma. GSK679586, a humanized mAb, inhibits IL-13 binding to both IL-13 receptor α1 and α2.

Dysregulated adipokine metabolism in chronic obstructive pulmonary disease.

Background: Research concerning the involvement of body composition and systemic inflammatory markers in adipokine metabolism in chronic obstructive pulmonary disease (COPD) is still limited. Therefore, we primarily aimed to investigate the adipokine metabolism in relation to these systemic inflammatory biomarkers and to evaluate possible gender-related differences in the adipokine metabolism in patients with COPD.

Materials And Methods: One hundred and eighty-six subjects with COPD [mean (SD) FEV(1) %pred: 50 (±16)] and 113 controls, matched for age, gender and body composition were selected from the ECLIPSE cohort.

Evaluation of exhaled breath condensate pH as a biomarker for COPD.

Introduction: We assessed the utility of EBC pH as a biomarker in COPD in a large cohort of well-characterised individuals with COPD and control subjects from the Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints (ECLIPSE) study. We also determined short term reproducibility and the response of EBC to oral prednisolone.

Methods: EBC was collected with R-Tubes(TM), using techniques for sampling and measurement that have been shown to be reproducible.

Determinants of depression in the ECLIPSE chronic obstructive pulmonary disease cohort.

Rationale: Depression is prevalent in patients with chronic obstructive pulmonary disease (COPD); however, its etiology and relationship to the clinical features of COPD are not well understood.

Objectives: Using data from a large cohort, we explored prevalence and determinants of depression in subjects with COPD.

Methods: The Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints study is an observational 3-year multicenter study that enrolled smokers with and without COPD and nonsmoker controls.

Real-world assessment of a metered-dose inhaler with integrated dose counter.

Currently available metered dose inhalers (MDIs) do not track the remaining number of doses, indicating the need for a device that accurately monitors medication use. In an open-label study at 37 outpatient centers, patients > or =4 years old with asthma or chronic obstructive pulmonary disease requiring short-acting 32-agonists received two actuations of albuterol hydrofluoroalkane (HFA) [Ventolin HFA: GlaxoSmithKline], 90 microg twice daily, via a novel MDI with an integrated dose counter until all 200 actuations were completed. Concordance between counter readings, diary card-recorded actuations, and canister weights were measured in patients who completed > or =90% of the labeled actuations (n = 224).
