Risk of Aspergillus Infection in Patients With Chronic Lung Disease

Completed
Conditions
Fungal Infection Lungs
Interventions
Other: No intervention
Registration Number
NCT06379568
Lead Sponsor
Lin Chen
Brief Summary

Large doses of systemic corticosteroids ,severe lung tissue damage and longer COPD diagnosis may increase the risk of IPA in patients with chronic structural lung disease. By comparing the risk factors of aspergillus colonization group and aspergillus infection group, the main risk factors of aspergillus pneumonia were determined.

Detailed Description

Patients with chronic lung disease were identified as positive for Aspergillus fumigatus through sputum microscopy. According to diagnostic criteria, patients diagnosed with IPA and CPA and were assigned to the Aspergillosis pneumonia group, while the remaining patients were included in the Aspergillus colonization group. Then,Risk factors for aspergillus pneumonia, invasive pulmonary aspergillus disease, and chronic pulmonary aspergillus disease, such as the use of high-dose corticosteroids, inhaled corticosteroids, and the extent of damage to basic lung structures, were identified by comparing the aspergillus colonization group with the aspergillus infection group.

Primary Outcome Measures
NameTimeMethod
The area under ROC curve of risk factors for aspergillus pneumoniaStatistical analysis was carried out after data collection within two month

The area under ROC curve (AUC) was used to evaluate the classification effect of the binary classification model among Aspergillus pneumonia group, IPA group and CPA group

Descriptive statistical indexInformation was collected on the day of admission

Summarize participant characteristics using means and standard deviations for continuous variables and frequencies for categorical variables

Independent risk factor for aspergillus pneumoniaStatistical analysis was carried out after data collection within one month

Independent risk factors for aspergillus infection were determined by multivariate logistic regression analysis.

Secondary Outcome Measures
NameTimeMethod
Threshold analysis of aspergillus pneumoniaStatistical analysis was carried out after data collection within two month

Specific cut-off values for Aspergillus specific IgG antibody × lung structural injury image score was determined to maximize diagnostic accuracy, focusing on sensitivity, specificity, and Youden index.
