Effects of Neutrophil Extracellular Traps and Damage-associated Molecular Pattern Molecules on Long Term Use of Macrolides in Adults With Chronic Respiratory Disease

Overview

The purpose of this study is to investigate the effects of neutrophil extracellular traps and damage-associated molecular pattern molecules on long term use of macrolides in adults with chronic respiratory disease.

This study is a prospective, observational, non-interventional cohort study to explore investigate the effects of neutrophil extracellular traps and damage-associated molecular pattern molecules on long term use of macrolides in adults with chronic respiratory disease.The study subjects were adult patients with chronic respiratory disease who met the inclusion criteria in the outpatient department from August 2021 to August 2023. A face-to-face questionnaire survey was conducted. ACT score was used for asthma control evaluation. Baseline data such as pulmonary function, FeNO, blood routine, induced sputum cell count, etc. were obtained. The use of hormones and other drugs was recorded. Inflammatory biomarkers were detected. 20ml venous blood was drawn to extract neutrophils to detect the expression of neutrophil extracellular traps and RT-PCR and ELISA were used to detect the expression of DAMPs. The total study duration was 2 years, with telephone visits every 3 months to assess chronic respiratory disease control and record subject compliance, unscheduled outpatient, emergency, and inpatient status.
