Chronic obstructive pulmonary disease (COPD) is a progressive, inflammatory lung that affects large number of patients and has significant impact. One hallmark the presence bacteria in lower airways.The aim this study was to analyze detailed structure microbial communities found lungs healthy individuals with COPD. Nine COPD as compared 9 underwent flexible bronchoscopy BAL performed. Bacterial nucleic acids were subjected terminal restriction fragment (TRF) length polymorphism clone library...

Chronic obstructive pulmonary disease (COPD) is associated with airway inflammation and bacterial dysbiosis. The relationship between the microbiome bronchial gene expression in COPD poorly understood. We aimed to identify differences from brushings patients healthy individuals investigate whether any distinguishing bacteria are related expression.For this 16S rRNA sequencing host transcriptomic analysis, aged 45-75 years mild-to-moderate either receiving or not inhaled corticosteroids same...

Abstract Activated caspase-1 and caspase-11 induce inflammatory cell death in a process termed pyroptosis. Here we show that Prostaglandin E 2 (PGE ) inhibits caspase-11-dependent pyroptosis murine human macrophages. PGE suppreses expression macrophages the airways of mice with allergic inflammation. Remarkably, caspase-11-deficient are strongly resistant to developing experimental airway inflammation, where is known be protective. Expression elevated lung wild type Blocking production...

Abstract Rationale and Objective Plasma extracellular vesicles (EVs) represent a vital source of molecular information about health disease states. Due to their heterogenous cellular sources, EVs cargo may predict specific pathomechanisms behind phenotypes. Here we aimed utilize EV microRNA (miRNA) signatures gain new insights into underlying mechanisms obesity‐associated low type‐2 asthma. Methods Obese asthma (OA) non‐obese (NOA) patients were selected from an cohort conjointly with...

Alpha1-antitrypsin (AAT) deficiency, although largely under-diagnosed, is the underlying cause of approximately 1% COPD cases. Lack awareness leads to long delays in diagnostic testing. Subsequently, lifestyle and treatment choices with potentially positive effects on prognosis may be postponed.Data testing practices for AAT deficiency were derived from University Pavia, Italy, Marburg, Germany. In addition, a survey physicians was undertaken explore their attitudes toward deficiency.In...

Patients with stable COPD show improvements in exercise capacity and muscular function after the application of whole body vibration. We aimed to evaluate whether this modality added conventional physiotherapy exacerbated hospitalised patients would be safe improve quality life. 49 were randomized (1:1) undergo alone or addition The primary endpoint was between-group difference 6-minute walking test (day discharge – day admission). Secondary assessments included chair rising test, life,...

α 1 -Antitrypsin deficiency (AATD) is a genetically determined disorder that associated with different clinical manifestations. We aimed to assess the prevalence of diagnosed AATD and its comorbidities using large healthcare database. In this retrospective longitudinal observational study, we analysed data from 4 million insurants. Using International Classification Diseases revision 10 (ICD-10) codes, assessed prevalence, utilisation patients (E88.0 repeatedly coded) relative non-AATD...

Abstract Background Chronic obstructive pulmonary disease (COPD) is an inflammatory multisystemic caused by environmental exposures and/or genetic factors. Inherited alpha-1-antitrypsin deficiency (AATD) one of the best recognized factors increasing risk for early onset COPD with emphysema. The aim this study was to gain a better understanding associations between comorbidities and specific biomarkers in patients without AATD enable future investigations aimed, example, at identifying or...

Despite recognition of asthma as a growing global issue and development guidelines, treatment practices vary between countries. Several studies have reported patients’ perspectives on control. This study presents physicians’ strategies for management. Physicians seeing ≥4 adult patients with per month in Australia, Canada, China, France, Germany, Japan were surveyed (N=1809; ≈300 country). A standardised questionnaire was developed this administered by telephone, online or face-to-face....

Dual bronchodilation combining a long-acting β2-agonist (LABA) and muscarinic antagonist (LAMA) is the preferred choice of treatment recommended by Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 guidelines management patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). The once-daily (q.d.) fixed-dose combination (FDC) LABA, indacaterol 110 μg LAMA, glycopyrronium 50 (IND/GLY 110/50 q.d.) demonstrated superior improvements in lung function,...

Abstract Background Whether the clinical or pathophysiologic significance of “treatable trait” high blood eosinophil count in COPD is same as for asthma remains controversial. We sought to determine relationship between count, characteristics and gene expression from bronchial brushings asthma. Methods Subjects were recruited into a (emphysema versus airway disease [EvA]) cohort (Unbiased BIOmarkers PREDiction respiratory outcomes, U‐BIOPRED). determined using RNAseq EvA (n = 283) Affymetrix...

Influenza A virus (IAV) causes severe respiratory infections and alveolar epithelial damage resulting in acute distress syndrome (ARDS). Extracellular vesicles (EVs) have been shown to mediate cellular crosstalk inflammation by transfer of microRNAs (miRNAs). In this study, we found significant changes the miRNA composition EVs bronchoalveolar lavage fluid from patients with IAV-induced ARDS. Among 9 significantly deregulated microRNAs, miR-17-5p was upregulated patients' BALF IAV-infected...
