Has the child diagnosed as allergic cough by the doctor been tested for allergens?

Spring is the season of frequent cough and high incidence of respiratory allergies. The data shows that in the past two months, the number of patients watching cough in the respiratory medicine clinic of Tianjin Maternal and Child Health Hospital has increased significantly. In the face of cough, everyone is always used to stopping cough first. In this regard, Liu Lixia, chief physician of respiratory medicine, said: Cough is a self-defense mechanism of human body, which can expel foreign bodies or secretions in respiratory tract, but severe cough will seriously affect work and life, and cough can lead to syncope, rib fracture and urinary incontinence. If the cause is not clear, indiscriminate use of antitussive drugs may not be able to stop coughing, but it will cover up or aggravate the condition.

Recently, Ms. Li from Xiamen, Fujian, took her 6-year-old daughter to the Department of Respiratory Medicine of Xiamen Children's Hospital. She told the doctor that Yiyi's cough symptoms had lasted for half a year. At first, Ms. Li thought Yi Yi just had a cold. After taking cold medicine, the discomfort symptoms such as headache have improved obviously, but the cough has been "stuck". "I have an itchy throat and a runny nose and sneezing from time to time. I feel chest tightness and asthma every time I cough. Especially at night, I have a worse cough and can't sleep at all. " Ms. Li tried a variety of cough relieving methods for Yiyi, but after four or five months, her cough still didn't get better. In desperation, she came to the hospital for examination.

Zhang Fanghua, chief physician of the Department of Respiratory Medicine of Xiamen Children's Hospital, speculated that Yiyi was probably allergic cough. Subsequent allergen tests showed that Yi Yi had a strong allergic reaction to cypress pollen and dust mites. Zhang Fanghua diagnosed that Yiyi's cough was actually due to allergic cough (also known as cough variant asthma) complicated with allergic rhinitis.

What are the roots of allergic cough?

The causes of allergic cough are varied and complicated, but they mainly include two aspects, namely, the physique and environmental factors of allergic cough patients. The constitution of patients includes subjective conditions such as "genetic quality", immune state, mental and psychological state, endocrine and health status, which is an important factor for patients to suffer from allergic cough. Environmental factors, including allergens, irritating gases, virus infection, living area, room conditions, occupational factors, climate, drugs, exercise (hyperventilation), food and food additives, eating habits, social factors and even economic conditions, may be the more important reasons for allergic cough. The rising trend of incidence in allergic cough is also related to the susceptibility and environmental factors caused by patients' allergic constitution.

How to treat allergic cough effectively?

The appearance of allergic cough has brought great pain to patients, because the disease is easy to recur, and it will also affect patients' mental health. So what is the best way to treat allergic cough? Allergic cough's treatment includes desensitization therapy, drug therapy and IGE therapy. It is very important to choose the right method to completely cure allergic cough.

1, desensitization therapy

Also known as desensitization therapy, or specific immunotherapy, the main antigen substances that are unavoidable and diagnosed or suspected by skin test or other methods are made into a certain concentration of leaching solution, and the specific antigen is injected into the patient repeatedly by gradually increasing the dose and concentration to promote the production of corresponding antibodies in the body.

2. Drug therapy

Allergic cough, generally treated with drug control. Many drugs selected for this kind of disease generally choose antihistamines to control the disease. Drugs have a good effect on the treatment of urticaria. If the patient's single use effect is not good, then combine the drugs, and then take them on time according to the doctor's advice, and soon the condition will improve.

3.IGE therapy

Modern medicine found that the fundamental cause of allergic cough's attack-IGE sensitized antibody was found from the immunological changes of allergic cough's attack. IgE is mainly synthesized in plasma cells of nasopharyngeal, bronchus, gastrointestinal tract, lamina propria of skin and mucosa where allergens invade. Among all kinds of immunoglobulins, the synthesis rate of -IgE is the lowest. If the self-synthesis ability of -IgE is too high, the more it binds to allergens and causes more inflammatory mediators such as histamine, allergic symptoms will appear. Then, controlling the synthesis rate of -IgE becomes the key to treat allergic cough! Xinminkang anti-allergic probiotics can reduce the production of specific IgE antibody in serum and promote the secretion of interferon in spleen cells. The anti-allergic probiotics of Xin, Min and Kang can enhance the TH 1 immune response, thus regulating the Th2 immune hyperactivity which is overreacted due to allergen stimulation, and stimulating the Th 1 immune response which can regulate the allergic immune response, so as to balance the TH2 immune response caused by allergy, thus achieving the effect of improving allergic constitution.

How to effectively prevent the recurrence of allergic cough?

1. When the seasons alternate and the temperature changes suddenly, parents should try to keep their children warm and cold to avoid catching a cold.

2. Avoid eating foods that can cause allergic symptoms, such as seafood, cold drinks and carbonated drinks.

3. In the bathroom or basement, dehumidifiers and air filters should be used, and the filters should be replaced regularly.

4. Don't keep pets and flowers at home, don't lay carpets, and avoid children's contact with pollen, dust mites, lampblack and paint.

5. Don't let children fall asleep with soft toys. Because dust mites are easy to attach to fur dolls, it is best not to put fur dolls on children's beds. If you must put fur dolls, it is best to wrap them in plastic bags or wash them with hot water every week, or put them in the refrigerator for several hours every week to prevent dust mites from breeding.

It is very important to choose the right method to cure allergic cough. I believe that every patient will know something after reading it. Because there are many treatment methods in allergic cough, patients and friends can't choose blindly, and symptomatic treatment is the most important.
