Overview
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.
Interventions
- Diagnostic test The level of biomarkers in Peripheral blood
All participants will be extracted 5ml peripheral blood into the anticoagulant tube by nurses and the peripheral blood will be detected for biomarkers of asthma. Children with asthma will take pulmonary function, blood test and specific IgE test etc. The lung function test will be performed by professional technicians and the results will be interpreted by specialists. The blood test and specific IgE test will be collected by specialist nurses and the results will be issued by professional inspe
Primary outcome measures
- The level of biomarkers [Time frame: 2years]
Secondary outcome measures (7)
