|Inflammatory Lung Diseases Hemoptysis|
|Study Type :||Observational|
|Estimated Enrollment :||52 participants|
|Observational Model:||Case Control|
|Official Title:||The Expression of Serum Angiogenesis Marker in Patients Presenting With Hemoptysis|
|Study Start Date :||June 2008|
|Actual Study Completion Date :||December 2010|
|patients with hemoptysis within 2 weeks|
|patients without hemoptysis within 2 years|
- serum VEGF and Ang-2 level in lung inflammatory disease according to the presence of hemoptysis [ Time Frame: up to 7 days after enrollment ]We'll measure the serum VEFG and Ang-2 level of enrolled patients within a week from the moment that patients agree to enroll this study. Therefore, Comparison of the serum VEGF and Ang-2 level (measured within a week from enrollment) according to the presence of hemoptysis will be primary outcome.
- to investigate association between angiogenesis factors and other factors such as inflammatory biomarker and hypoxia. [ Time Frame: up to 7 days after enrollment ]We'll measure the serum VEFG, Ang-2 level, and other factors such as inflammatory biomarkers and PaO2 of enrolled patients within a week from the moment that patients agree to enroll this study. Therefore, Investigating association between angiogensis factors and other factors such as inflammatory biomarker and hypoxia, which were measured within a week from enrollment, will be secondary outcome.
