An analyse of clinical features and affecting factors on 200 cases of pediatrical asthma in Beijing

Objective To understand the relationship between the onsetage, the severity of asthma and the allergic disease, the influence of the way of giving birth, feeding manner, family history of allergic disease on incidence of asthma, and the proportion of food and inhale allergen in the children with asthma. Methods We investigated 200 children with confirmed asthma, including the onset of disease, the severity, the other allergic diseases, the history of birth, feeding and family, and 150 cases of healthy children as control group.We also measured serum-IgE. Results The onset age of 92.0% patients is younger than 6 years old, 93.7% of patients were mild and moderate asthma.Among the 200 cases, 52.5%、55.5%、26.5%、1.5%, 15.5%, 10.5% of patients with a history of rhinitis, eczema, urticaria, intestine allergy, drug allergy and food allergy separately.51.0% of them were normal delivery, 21 % were artificial feeding, 53.7% of patients had a family history of allergic diseases, 46.6 % with positive FX5E and 50.4 % with positive Phadiatop. Conclusion The patients of asthma usually had a early onset age, with strong tendency of family history of allergic disease.There are close relationship between the asthma and allergic disease.The positive rate of inhale and food allergy is higher among them.It also suggests that artificial feeding was a high risk factor.
