Interleukin(IL)-33 is an epithelial alarmin important for eosinophil maturation, activation and survival. The aim of this study was to examine the association between IL-33, its receptor expression airway eosinophilic inflammation in non-atopic COPD. IL-33 concentrations were measured exhaled breath condensate (EBC) collected from healthy non-smokers, asthmatics COPD subjects using ELISA. Serum sputum samples smokers patients.

Background Although chitin is absent in humans, chitinases are present healthy subjects and show dysregulated expression a variety of diseases resulting from abnormal tissue injury repair responses. It was shown that chitotriosidase (chitinase 1/CHIT1) structurally-related chitinase 3-like 1 protein (CHI3L1/YKL-40) play important roles the pathobiology idiopathic pulmonary fibrosis (IPF), however little known about their longitudinal serum levels relationship to clinical measures IPF....

Exacerbations of Chronic Obstructive Pulmonary Disease (AECOPDs) are one the most important clinical aspects disease, and when requiring hospital admission, they significantly contribute to mortality among COPD patients. Our aim was assess role eosinopenia neutrophil-to-lymphocyte count (NLR) as markers in-hospital length hospitalization (LoH) patients with ECOPD hospitalization. We included 275 Eosinopenia associated deaths only coexisted lymphocytopenia, specificity 84.4% (95% CI...

Chronic obstructive lung diseases, such as asthma and COPD, appear to have a more extensive impact on overall functioning than previously believed. The latest data from clinical trials suggests potential link between cognitive deterioration chronic inflammatory disease. This raises the question of whether these diseases affect functions any relevant biomarker may be identified.

Background: Despite the absence of endogenous chitin in humans, chitinases are present serum healthy subjects and their levels increased a variety chronic inflammatory conditions. It has been shown that chitotriosidase structurally related chitinase-like protein-YKL-40 contribute to pathogenesis COPD. However, details regarding relation systemic local airways remain unknown. Objectives: To examine peripheral blood sputum YKL-40 expression smokers patients with Methods: Forty COPD, 20 10...

Abstract COPD has been regarded as a global epidemic due to an increase in pollution and tobacco exposure. Therefore, the study of molecular mechanism basis for modern therapy is important. The aim was assessment gene expression levels, IL-6 , IL-6ST PIAS3 STAT3 miRNAs, miRNA-1, miRNA-106b, miRNA-155, patients with COPD. Induced sputum well PBMC were collected from 40 clinically verified according GOLD 2021 (A–D) classification control group (n = 20). levels miRNA analysed by qPCR. In...

Little is known about the expression of IPF. This study aimed prospectively examine interleukin (IL)-25, IL-33, and thymic stromal lymphopoietin (TSLP) levels serum exhaled breath condensate (EBC) patients with IPF before after one-year antifibrotic treatment. A total 82 volunteers, including 52 diagnosed that qualified for therapy as...
