Winter is the season when children are easy to get sick. At this time, we often see parents taking their children to the hospital. At this time, children are very prone to cough. Many parents think that it is just a simple cold and cough symptom, but they still don't get better after taking medicine, and they have a long cough. At this time, parents should attach great importance to it. This may be allergic cough, one of the common respiratory diseases in children. So how should parents deal with allergic cough? 　

What are the symptoms of allergic cough in children?

1 Many children will have cough symptoms when they catch a cold or have a fever, which is caused by internal heat. However, if the child does not show any signs of fever, he only shows cough symptoms, and he does not gasp when coughing, and the symptoms do not improve after taking anti-inflammatory drugs. This is about to attract the attention of parents. At this time, parents should also observe whether children show little gestures like rubbing their eyes and nose and scratching their scalp in their daily lives. Parents should also pay attention to whether children are very unstable when sleeping, do not like lying flat, like curling up, and sweat more than usual when sleeping. If these symptoms appear, most of them may have suffered from allergic cough in children.

2. The frequency of allergic cough in children is different from that of common cough on weekdays. The period of allergic cough's attack in children is long, and the attack time is generally more than 4 weeks, and the longer one is chronic cough 180 days. Moreover, the cough time is mainly three periods: before going to bed at night, waking up in the middle of the night and waking up in the morning. In addition, if you exercise, your cough will get worse.

3. If children have had allergic symptoms, have suffered from infantile eczema and urticaria, or have had symptoms of food allergy, the probability of suffering from allergic cough is greatly increased.

What are the treatment methods for allergic cough in children?

Clinical medicine has proved that helper T cells and their cytokines play an important role in regulating the composition of IgE. According to the variety of excreted cytokines, helper cells are divided into two subgroups: TH 1 and TH2. Cytokines excreted by TH2 cells play an important role in antibody formation and allergic reaction. TH 1 and TH2 are mutually regulated by cytokines. In healthy conditions, TH 1 and TH2 are balanced and regulated by helper T cells at the same time. When helper T cells are deficient in regulation ability or come into contact with some heterosexual protein or fine molecules (such as dust mites, pollen or seafood, etc.), TH2 is over-activated, resulting in excessive secretion of TH2 cell hormones, which leads to the increase of IgE. To reduce IgE antibody, it is necessary to supplement the anti-allergic probiotics that can reduce serum IgE antibody.

The antiallergic probiotics adopt a physiologically acceptable probiotic composition with enhanced antiallergic ability. By promoting the secretion of interleukin 12(IL- 12) and interferon gamma, allergic symptoms can be effectively improved, and Th 1 type immune response can be regulated to inhibit immunoglobulin IgE and improve the allergic phenomenon of Th2 type immune response. The anti-allergic probiotic strains of Xin, Min and Kang combine with receptors on dendritic cells on intestinal wall, and the translated proteins in activated cells move to the nucleus and release a large number of cytokines, which belongs to a link of innate immunity. Therefore, diabetic substances such as peptidoglycan, lipopolysaccharide and polysaccharide on their cell walls can really activate the development of T cells through the innate immune system.
