Clinical Trial Summary

The goal of this observational study is to 1)analyze the basic information of confirmed cases of asthma in children aged 5-12 years old hospitalized in the First Affiliated Hospital of Guangzhou Medical University from 2009 to 2020, 2)investigate the onset of asthma after 13 years old, 3)conducte lung function, blood and airway inflammation indicators, blood IL13 and IL1RL1 levels, 4)analyze the prognosis and influencing factors of children with asthma in this age group.Participants will be asked to fill a case report form and questionnaires. Besides, they should provide examination results like lung function, total IgE, expired nitric oxide, blood and sputum granulocyte counts, and determination of blood IL13 and IL1RL1 levels over the past 6 months.

Description:

Research methods: Part I: Retrospective analysis of hospitalized cases of asthma in children aged 5-12 years old from 2009 to 2020: (1) General information of the children (gender, age and BMI); (2) Special medical history of parents; (3) The history of respiratory virus infection in the early life; (4) that age of the first occurrence of asthma; (5) The number of wheezes in the 12 months before the diagnosis of asthma; (6) Specificity; (7) trigger factors of symptoms; (8) Time pattern of symptom manifestations; (9) Illness severity; (10) Airway inflammation pattern; (11) Baseline of lung function; (12) Anti-inflammatory treatment; (13) Reactions to drug therapy. (14) coinfected diseases or complications. (15) Genetic information. Part II: Patients who are lost to follow-up will be excluded. The patients will be divided into asthma relief group and asthma continuation group according to whether they had relapsed asthma after 13 years old. The case report form and C-ACT/ACT questionnaire will be filled out. Patients should provide examination results like lung function, total IgE, expired nitric oxide, blood and sputum granulocyte counts, and determination of blood IL13 and IL1RL1 levels over the past 6 months. Part III: Univariate and multivariate analyses will be performed for different prognostic outcomes of asthma in children aged 5 to 12 years.
