The International Severe Asthma Registry (ISAR) was established in 2017 to advance the understanding of severe asthma and its management, thereby improving patient care worldwide. As first global registry for adults with asthma, ISAR enabled individual registries standardize pool their data, creating a comprehensive, harmonized dataset sufficient statistical power address key research questions knowledge gaps. Today, is largest repository real-world data on curating nearly 35,000 patients...

ABSTRACT Background and Objective Symptom‐based questionnaires handheld lung function devices are widely used for COPD case finding, but the optimal combination remains unclear. This study aimed to compare diagnostic accuracy (DA) of various combinations develop a case‐finding strategy. Methods cross‐sectional, prospective, observational enrolled participants aged ≥ 40 years with respiratory symptoms 10 smoking pack‐years. Participants completed three (COPD questionnaire [CDQ],...

Airway remodeling with smooth muscle cell (SMC) hyperplasia is a feature of chronic asthma. We investigated the potential for tryptase, major secretory product human mast cells, to act as growth factor airway SMCs. Because this serine protease can activate proteinase-activated receptor-2 (PAR-2), we also examined actions SLIGKV, peptide agonist PAR-2. Incubation lung tryptase provoked twofold increase in [ 3 H]thymidine incorporation; similar numbers was found when used MTS assay. The effect...

Asthmatic patients have higher numbers of mast cells in the smooth muscle layer airways than normal subjects. Human airway (HASMCs) are a source various cytokines including transforming growth factor beta1 (TGF-beta1), which is chemotactic for cells. We thus examined potential interaction between HASMCs and investigated, particular, hypothesis that after stimulation, can induce cell chemotaxis through production cytokines. Supernatants treated with major product tryptase had increased...

Abstract Allergenic serine proteases are important in the pathogenesis of asthma. One these, Pen c 13, is immunodominant allergen produced by Penicillium citrinum. Many induce cytokine expression, but whether 13 does so human respiratory epithelial cells not known. In this study, we investigated caused IL-8 release and activated protease-activated receptors (PARs) airway cells. airway-derived A549 normal cells, induced a dose-dependent manner. also increased time-dependent manner cleaved...

Cysteinyl leukotrienes (CysLTs) play an important role in the pathogenesis of airway remodeling. We investigated interaction between epithelium and CysLTC4, contribution this to fibrosis. Human epithelial cells were grown on air-liquid interface culture inserts. CysLTC4 was employed stimulate cells. Conditioned medium following stimulation coincubated with human lung fibroblasts. Our results have demonstrated that stimulates cells, through a p38 mitogen-activated protein kinase (MAPK)...

ABSTRACT Chronic obstructive pulmonary disease (COPD) is a major in Asia. However, how to manage specifically Asian COPD patients has not been proposed. Awareness of very low and underdiagnosis/undertreatment common countries. Low utilization function test inhalers also problem. Moreover, high smoking prevalence air pollution are barriers managing with COPD. The relatively body mass index can increase their risk for experiencing adverse effects from drugs. Physicians should consider the...
