The Role of Biomarkers in the Occurrence and Development of Asthma

Recruiting
Conditions
Asthma in Children
Interventions
Diagnostic Test: The level of biomarkers in Peripheral blood
Registration Number
NCT05768399
Lead Sponsor
Children's Hospital of Chongqing Medical University
Brief Summary

To study the expression level of biomarkers such as GITRL in peripheral blood of children with asthma and analyze their correlation with the severity of asthma. To study the predictive value of biomarkers level for the occurrence and development of asthma. And to provide supplementary detection means and predictive indicators for the diagnosis of asthma and the severity of asthma.

Detailed Description

Recruit 30 children with asthma and 30 healthy children based on the consent of the children and their parents or their guardian. Collect and record general information such as name, age, time of first diagnosis, allergens or triggers, daily dosage and frequency of asthma control drugs, home address and contact information. Collect 5 ml of blood sample for the detect of the biomarkers. Asthma severity was assessed using pulmonary function by spirometry and score of C-CAT. Finally study the correlation between the level of biomarkers and asthma severity and the role of biomarkers in the occurrence and development of asthma.
