The Relationship Between Total Sialic Acid and Superoxide Dismutase and the Diagnosis and Prognosis of Lipoid Pneumonia

Overview

The goal of this observational study is to explore the correlation between total sialic acid combined with superoxide dismutase and the diagnosis and prognosis of lipid pneumonia in the patient with lipid pneumonia, cough, bacterial and fungal pneumonia, cryptogenic organizing pneumonia, pulmonary alveolar proteinosis, lung mucinous adenocarcinoma and pulmonary edema. The main question it aims to answer is: Whether superoxide dismutase (SOD) and total sialic acid (TSA) could be used as diagnostic markers to distinguish lipid pneumonia from patient with cough, and bacterial and fungal pneumonia, cryptogenic organizing pneumonia, pulmonary alveolar proteinosis, lung mucinous adenocarcinoma and pulmonary edema, whether SOD and TSA be associated with the prognosis of patients with lipid pneumonia? Participants will answer online survey questions about their symptoms, changes in oxygen status, and changes in the most recent CT image of the lung for up to 10 years after treatment. We will count participants' baseline data including: gender, age, smoking history, comorbidities, lung function, imaging findings, hormone use or not, ICU treatment, death or not, the type of cause of lipid pneumonia, how it is diagnosed, and their baseline SOD and TSA.
