Background Although inhaled corticosteroids (ICS) are highly effective in asthma, they provide significant, but modest, clinical benefit in COPD. Here, we tested the hypothesis that high bronchial airway smooth muscle cell (ASMC) area in COPD is associated with ICS responsiveness. Methods In this investigator-initiated and -driven, double-blind, randomised, placebo-controlled trial (HISTORIC), 190

TLR7/8 activation induces autoimmune vasculopathy and causes severe pulmonary arterial hypertension Eur. Respir. J. (IF 24.3) Pub Date : 2023-07-20 Fu-Chiang Yeh, Chien-Nien Chen, Chong-Yang Xie, Nicoleta Baxan, Lin Zhao, Ali Ashek, Farah Sabrin, Allan Lawrie, Martin Wilkins, Lan Zhao
Extract Growing evidence supports the contention that immune dysregulation and autoimmunity predispose and contribute to the pathological remodelling that characterise pulmonary arterial hypertension (PAH) [1, 2]. PAH is a common complication of connective tissue diseases (CTDs), especially systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) [3]. In addition, idiopathic PAH (IPAH) patients

European Respiratory Society statement on airway clearance techniques in adults with bronchiectasis Eur. Respir. J. (IF 24.3) Pub Date : 2023-07-20 Beatriz Herrero-Cortina, Annemarie L. Lee, Ana Oliveira, Brenda O'Neill, Cristina Jácome, Simone Dal Corso, William Poncin, Gerard Muñoz, Deniz Inal-Ince, Victoria Alcaraz-Serrano, Gregory Reychler, Angela Bellofiore, Annette Posthumus, Patient representative, Thomy Tonia, James D. Chalmers, Arietta Spinou
Airway clearance techniques (ACTs) are part of the main management strategy for patients with bronchiectasis. Despite being a priority for patients, accessibility, implementation and reporting of ACTs are variable in clinical settings and research studies. This European Respiratory Society statement summarises current knowledge about ACTs in adults with bronchiectasis and makes recommendations to improve

Effect of listening to breathing recordings on self-reported breathlessness: a public experiment Eur. Respir. J. (IF 24.3) Pub Date : 2023-07-20 Natasha Lovell, Simon N. Etkind, Joanna M. Davies, Wendy Prentice, Irene J. Higginson, Katherine E. Sleeman
Extract Breathlessness is a common and persistent symptom for those living with chronic lung conditions and advanced disease [1]. It can be distressing for those who experience it, and often results in anxiety, physical inactivity and a poorer quality of life [2, 3]. Additionally, it impacts significantly on those who are close, including friends and family, and is associated with a considerable care

Oxidised IL-33 drives COPD epithelial pathogenesis via ST2-independent RAGE/EGFR signalling complex. Eur. Respir. J. (IF 24.3) Pub Date : 2023-07-13 Sam Strickson,Kirsty F Houslay,Victor A Negri,Yoichiro Ohne,Tomas Ottosson,Roger B Dodd,Catherine Chaillan Huntington,Tina Baker,Jingjing Li,Katherine E Stephenson,Andy J O'Connor,J Sophie Sagawe,Helen Killick,Tom Moore,D Gareth Rees,Sofia Koch,Caroline Sanden,Yixin Wang,Elise Gubbins,Mahboobe Ghaedi,Roland Kolbeck,Saumyaa Saumyaa,Jonas S Erjefält,Gary P Sims,Alison A Humbles,Ian C Scott,Xavier Romero
BACKGROUND Epithelial damage, repair and remodelling are critical features of chronic airway diseases including chronic obstructive pulmonary disease (COPD). Interleukin (IL)-33 released from damaged airway epithelia causes inflammation via its receptor, serum stimulation-2 (ST2). Oxidation of IL-33 (IL-33ox) to a non-ST2-binding form is thought to limit its activity. We investigated whether IL-33ox

ATAC-ing single nucleus in idiopathic pulmonary fibrosis: TWIST1 strives back for myofibroblasts Eur. Respir. J. (IF 24.3) Pub Date : 2023-07-07 Olivier Burgy, Arnaud A. Mailleux
Extract Ageing is often associated with chronic remodelling, which is a key feature of many human diseases, including chronic respiratory diseases such as lung fibrosis. Idiopathic pulmonary fibrosis (IPF) is the most common form of pulmonary fibrosis and is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause. IPF patients have an overall median survival

More is better? Hypertonic saline dose and response for cystic fibrosis: efficacy, tolerability and implications for clinical practice Eur. Respir. J. (IF 24.3) Pub Date : 2023-07-07 Scott H. Donaldson
Extract Improving lung function, preventing pulmonary exacerbations, and reducing symptoms are primary objectives in the development of inhaled therapeutics for cystic fibrosis (CF) lung disease. Hypertonic saline (HS) emerged as a simple and cost-effective treatment that achieved these goals early in the rapidly evolving era of CF drug development. HS addresses an important pathophysiological abnormality

Air pollution and COVID-19 severity Eur. Respir. J. (IF 24.3) Pub Date : 2023-07-07 Jordi Sunyer, Payam Dadvand
Extract Air pollution may elevate the risk of infection and severity (e.g. intensive care unit (ICU) admission and death) from coronavirus disease 2019 (COVID-19) by modifying host susceptibility to infection and disease severity, and by elevating the risk of comorbidities [1]. An emerging body of toxicological and experimental evidence has provided insights on how acute [2] and chronic [3] air pollution

Incidence of chronic thromboembolic pulmonary hypertension after acute pulmonary embolism: an updated systematic review and meta-analysis Eur. Respir. J. (IF 24.3) Pub Date : 2023-07-07 Dieuwke Luijten, Rosa Talerico, Stefano Barco, Suzanne C. Cannegieter, Marion Delcroix, Yvonne M. Ende-Verhaar, Menno V. Huisman, Stavros Konstantinidis, Albert T.A. Mairuhu, Thijs E. van Mens, Maarten Ninaber, Piotr Pruszczyk, Anton Vonk Noordegraaf, Frederikus A. Klok
Extract Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe late complication of acute pulmonary embolism (PE) [1, 2]. The earlier CTEPH is diagnosed, the better the prognosis for CTEPH patients, both in terms of survival and quality of life [2–4]. Even with this knowledge, the diagnostic delay of CTEPH still remains considerably long with a reported median duration of 14.1 months in
