Allergic cough's symptoms:
1. Chronic cough for more than four weeks without cause; Children with severe cough will have nausea or vomiting;
2. The pulmonary ventilation function is normal and the airway hyperresponsiveness test is negative;
3. The attack is often related to the environment or time, such as aggravation in the morning and evening or at night, aggravation at home and outdoor relief.
4. Do not have a fever, which may be accompanied by an itchy throat.
5. One of the following indications: contact history of allergic substances; B allergen skin test is positive; C serum total IgE or specific IgE increased; Cough sensitivity increases.
6. Antihistamines and glucocorticoids are effective.
Treatment of allergic cough in children.
Bronchodilator is ineffective. Histamine H 1 antagonists, such as azelastine, cetirizine, fexofenadine, olopatadine, etc. It might work. However, the overall effective rate is about 60%, and glucocorticoid treatment is often needed to completely relieve it. If the cough degree is obvious and inhaled hormone can't solve the problem, oral hormone 1-2 weeks is needed to relieve symptoms like cough variant asthma and asthma.
Immune preparations should reduce specific IgE antibodies in the body, such as Tamiflu, an antiallergic probiotic strain. The special components on the cell wall of Tamiflu combine with the receptors of intestinal epithelial cells, which can participate in the balance regulation of immune system, help reduce the production of specific IgE antibodies in serum and promote the secretion of interferon in spleen cells. In the animal model, it can be found that the way to inhibit allergic reaction by oral administration of Tamiflu probiotic strain is 1. Anti-allergic probiotics can reduce the proportion of eosinophil infiltration and alleviate inflammatory reaction. Conclusion: Allergic probiotics have the potential to treat allergic tracheal diseases.
Children with variant asthma in allergic cough were treated with Shunning or glucocorticoid inhalation and supplemented with Tamiflu anti-allergic probiotics. The course of treatment is not less than 8 weeks, which can shorten the treatment cycle of western medicine, give play to the ability of immune regulation, help regulate allergic constitution, and reduce the recurrence rate of allergy or drug withdrawal.
