Abstract
The distribution characteristics of pathogenic bacteria and the related health risk of pulmonary infection in patients with chronic obstructive pulmonary disease (COPD) were retrospectively analyzed to develop targeted measures to enhance patient prognosis. A retrospective analysis was conducted on the clinical data of 108 patients with COPD complicated with pulmonary infection and 108 patients without pulmonary infection. Analyze the distribution of pathogens in the lung infection group. Perform univariate analysis on the general data of two groups of patients and use multivariate logistic regression analysis to screen for independent risk factors affecting pulmonary infection in COPD patients. The results of univariate analysis showed that the ratio of patients aged ≥ 60 years, complicated with diabetes, duration of hospitalization ≥ 15 days, type of antimicrobial agents ≥ 2, and transforming growth factor-β (TGF-β) and serum tumor necrosis factor-α (TNF-α) in the pulmonary infection group were significantly greater than those in the group without pulmonary infection. Forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1) were significantly lower than in the group without pulmonary infection (P < 0.05). Multivariate Logistic regression analysis showed that unrelated health risks for pulmonary infection in COPD patients were age ≥ 60 years, length of hospitalization ≥ 15 days, combination of diabetes mellitus, and use of ≥ 2 types of antibacterial drugs. Age ≥ 60 years old, hospital stay ≥ 15 days, diabetes patients, and antibacterial drugs ≥ 2 are the risk factors of COPD patients with pulmonary infection.
期刊介绍:
Our mission is to publish peer-reviewed papers in all branches of medical sciences including basic medicine, social medicine, clinical medicine, nursing sciences and disaster-prevention science, and to present new information of exceptional novelty, importance and interest to a broad readership of the TJEM.
The TJEM is open to original articles in all branches of medical sciences from authors throughout the world. The TJEM also covers the fields of disaster-prevention science, including earthquake archeology. Case reports, which advance significantly our knowledge on medical sciences or practice, are also accepted. Review articles, Letters to the Editor, Commentary, and News and Views will also be considered. In particular, the TJEM welcomes full papers requiring prompt publication.
