Macrophages-the immune effector guardians of the lung: impact of corticosteroids on their functional responses.

Clin Sci (Lond) 2020 Jul;134(13):1631-1635

Department of Respiratory Medicine, University of Occupational and Environmental Health, Kitakyushu City 807-8555, Fukuoka, Japan.

Lung macrophages (LMs) are key immune effector cells that protect the lung from inhaled particulate matter, noxious gases and pathogens. In Chronic Obstructive Pulmonary Disease (COPD), there is an abundance of macrophages in airspaces and lung tissues suggesting that they play an important role in the pathogenesis of the disease. Furthermore, macrophage phenotype and functional properties are altered in COPD toward a more pro-inflammatory state, characterized by reduced pathogen recognition and processing ability and dysfunctional tissue repair qualities.

A TASMAN Expedition: Development of a Questionnaire to Assess Specific Self-Management Abilities.

Int J Chron Obstruct Pulmon Dis 2020 19;15:1415-1423. Epub 2020 Jun 19.

Department of Medical Psychology, Leiden University Medical Centre, Leiden, the Netherlands.

Introduction: Self-management (SM) is a core component of well-being and perceived health for patients with chronic obstructive pulmonary disease (COPD). Most theories on SM share that self-efficacy, illness-perception and coping are determinants of SM behavior. Optimal support to improve SM should be tailored to the individual patient's level of these determinants as SM abilities vary between patients. Read More

Detection of Cell-Dissociated Non-Typeable in the Airways of Patients with Chronic Obstructive Pulmonary Disease.

Int J Chron Obstruct Pulmon Dis 2020 12;15:1357-1365. Epub 2020 Jun 12.

Respiratory Medicine Unit, Nuffield Department of Medicine, University of Oxford, Oxford, UK.

Background: Non-typeable (NTHi) is the most commonly found pathogen in the lower respiratory airways of patients with COPD. NTHi is predominantly regarded as an intracellular pathogen; however, like most pathogens, it can exist and co-exist in two broad forms: cell-associated (intracellularly or adhered to cells) or cell-dissociated (biofilm dispersed or planktonic). We sought to investigate if cell-dissociated NTHi can be detected from the sputum of COPD patients and assess this relationship to disease severity and airway inflammation. Read More

Effectiveness and Tolerability of LABA/LAMA Fixed-Dose Combinations Aclidinium/Formoterol, Glycopyrronium/Indacaterol and Umeclidinium/Vilanterol in the Treatment of COPD in Daily Practice - Results of the Non-Interventional DETECT Study.

Int J Chron Obstruct Pulmon Dis 2020 10;15:1335-1347. Epub 2020 Jun 10.

Insaf - Respiratory Research Institute GmbH, Wiesbaden, Germany.

Background: LABA (long-acting β2-agonists) and/or LAMA (long-acting muscarinic antagonists) represent the first treatment options for patients with symptomatic COPD. Although both display different mechanisms of activity, in combination they have a stronger broncho-dilating effect than monotherapy; hence, a combination of both LABA and LAMA is particularly recommended for patients whose symptoms cannot be sufficiently improved by a single active ingredient. To date, only few data have been collected regarding the therapeutic outcomes of approved LABA/LAMA fixed-dose combinations (FDCs) under everyday (real-life) conditions in non-clinical trial settings.
