About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

In line with the diagnostic criteria in the Guidelines for the Diagnosis and Prevention of Bronchial Asthma in Children (2016 Edition)

Age: 4-12 years old for new diagnosis or recurrent episodes

Typical clinical manifestations and complete clinical data

Family members or guardians of children with informed research and signed consent

Disqualifiers

Suffering from other respiratory diseases (such as bronchiectasis, allergic rhinitis, respiratory failure, tuberculosis, obstructive airway disease) or other inflammatory diseases.

Abnormal development of congenital airway and lung tissue

History of immunosuppressant or glucocorticoid use in the first 4 weeks

Suffering from other endocrine system and immune system diseases

Trial population

Children with typical asthma symptoms, such as cough, wheezing, chest tightness, dyspnea and abnormal lung function tests, were diagnosed with asthma by a respiratory doctor

Trial design

Design model

Case-control

Time perspective

Prospective

Treatments tested in this trial

  • The level of biomarkers in Peripheral blood

    Diagnostic test

    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 inspectors. Children with asthma and their guardians will be asked for filling the questionnaire of Childhood Asthma Control Test (C-ACT). And then the doctor will check and calculate the scores after completion.

Treatment groups

2 Participants
are divided into 2 treatment groups
Group A: Asthma group1 intervention
Group B: Control group1 intervention
