Detailed Description
Asthma is one of the most common chronic diseases all over the world. GINA (Global Initiative for Asthma) reported that nearly 300 million were diagnosed with asthma, while in China even reach to 30 million. In recent years, the prevalence of pediatric asthma and severe cases in China has increased considerably. In 2013, the third national survey carried out in 43 cities in 27 provinces and found that asthma prevalence among children aged 0-14 years old reached to 3.02%, with the highest prevalence in Shanghai (7.57%), while in year of 2000, the rat was 1.09%. However, the research about mechanism, risk factors, individualized prevention and treatment strategy of asthma in China is still not perfect and there is no basic data and multicenter cohort study. Therefore, this multicenter cohort study is conducted, in order to set up a complete database, biobank and long term follow up of Chinese children, and establish foundations for basic research and precise medicine.
Pediatric patients more than or equal to 6 years old diagnosed with asthma will be recruited in this study. After evaluating the baseline, the patients were followed up. Visiting doctors and filling in a questionnaire for every three months, the clinical symptoms, physical examination, will be detected. Chest X ray, blood tests, lung function test and FeNO test would be done when necessary. And, biological samples of blood, urine and throat swab will be collected when recruiting and finishing follow-up. The trial will be completed in 60 months, with 4000 subjects recruited from 8 hospitals.

Description
Inclusion Criteria:
- Age: More than or equal to 6 years old
- Fulfilling the diagnosis criteria of asthma or cough variant asthma (CVA) based on the guideline of China.
- The patients cooperated very well with the doctors to perform lung function test.
Asthma is defined as fulfilling followings 1-4 or 4 and 5:
- History of variable respiratory symptoms: wheezing, shortness of breath, chest tightness, and coughing. Symptoms are often worse at night or upon awakening, and often triggered by exercise, laughter, allergens, or cold air, viral infections.
- At onset, scattered wheeze in the lungs is heard with prolonged expiratory time.
- The above symptoms and signs were efficient for anti-asthma, or alleviates voluntarily.
- Exclusive of other diseases with wheezing, shortness of breath, chest tightness, and coughing.
If the manifestation is non-typical, fulfilling one of the followings:
Documented airflow limitation:
- Positive BD reversibility test: Increase in FEV1 of >12% from baseline, 15 minutes after inhalation of 200-400 μg albuterol;
- Significantly increased in lung function after anti-inflammatory treatment;
- Increase in FEV1 of >12%, after 4 to 8 weeks of treatment with inhaled corticosteroids and (or) anti-leukotrienes.
- Positive bronchial challenge test;
- Excessive variability in twice-daily PEF over 2 weeks: Average daily diurnal PEF variability >13%.
Cough variant asthma (CVA) is defined as fulfilling following:
- Cough at least 4 weeks without sputum and wheeze, worsening at night or upon awakening;
- No symptoms of infection, or no effect on long term antibiotic treatment;
- The symptoms and signs were efficient for anti-asthma treatment;
- Exclusive of other diseases causing wheeze;
- Positive exercise challenge test and (or) average daily diurnal PEF variability >13%;
- Individual or primary, secondary relatives with allergic history, or positive allergen detection.
Exclusion Criteria:
Subject will be excluded if she or he has one of the following:
- congenital heart disease;
- heart failure;
- liver failure or renal insufficiency;
- kidney disease;
- connective tissue disease;
- immunodeficiency;
- tumor;
- a history of hypertension or diabetes mellitus.
