Early Screening of Young COPD and Pre-COPD

Sponsor: yanmengkang

Summary

At present, patients with early COPD and pre-COPD have not been paid attention to in clinical work. This study aims to actively screen such patients in high-risk groups to clarify their prevalence, monitor and analyze relevant clinical and biological indicators, and find sensitive indicators to assist in early diagnosis. Based on the updated definition of COPD in GOLD2022, we pay attention to the concept of early COPD and pre-COPD. After the completion of patient enrollment and data collection, we will further explore the effect of triple inhaled drug intervention on the development of lung function in patients with early COPD and pre-COPD, so as to provide clinical support for early screening and early treatment of COPD. 1. Patients with early COPD and pre-COPD were selected from 20 hospitals in 17 cities of Shandong province to understand the prevalence and basic characteristics of such diseases in the province, and then were divided into groups and treated. 2. The specificity and sensitivity of pulmonary function parameters (FEV1%,FEV1/FVC, DLco, etc.) and imaging parameters (MLD, Perc15, %LAA-950HU, etc.) alone or in combination in the diagnosis of early COPD and pre-COPD, and the predictive diagnostic model/system was established. 3. Treatment of early COPD and pre-COPD: eligible patients were given triple inhalation therapy or placebo, and the effects of triple inhalation therapy or not on clinical symptoms, pulmonary function, and imaging parameters were compared. This study aims to determine the prevalence of early COPD in Shandong province and provide a reference for the treatment of this population.
