Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Focusing on patients with diabetes complicated with pulmonary infection, the purpose of this study is: 1) to identify the epidemiology, etiologic spectrum and status of diagnosis and treatment; 2) to develop a symptom score scale , clarify the risk factors and create a precise warning model; 3) to develop a rapid detection of pathogen of lower respiratory infection, to establish clinical pathways of early diagnosis and treatment of diabetes complicated with pulmonary infections (including bacterial, tuberculosis and fungal infections) and then make an application in clinic.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Investigators perform a observational study on 6000 patients with diabetes, among which 200 patients with pulmonary infection are included in a retrospective study and 100 patients go through metabolomics research. All patients receive clinical questionnaires, laboratory examinations and pulmonary function tests. Investigators study on pathogen distribution and infection ratio of patients above depending on follow-up survey. 1:1 nested case-control study is carried out involving 100 cases from pulmonary-infected group paired with 100 control cases matched for gender, age and fasting blood-glucose. The final purpose is to create a precise warning model in order to develop a rapid detection of pathogen of lower respiratory infection in diabetes patients. Now investigators wish to register this study to do a further research, in order to improve the early diagnosis of diabetes complicated with pulmonary infection and to reduce the mortality.
