I am an allergic rhinitis patient, and I began to be allergic when I arrived in early autumn. I'm sick again these days.

From July to September every year, the number of patients with allergic rhinitis and allergic asthma in northern China increased significantly. Most allergic symptoms are itchy nose, sneezing, runny nose, stuffy nose, itchy eyes, increased secretion of lacrimal gland, accompanied by itching of maxillary and external auditory canal. In severe cases, symptoms such as cough and asthma may occur. Some people have headaches, irritability, depression, loss of appetite, insomnia, and a few people have vulva and anal pruritus.

The typical symptoms of seasonal allergic rhinitis caused by pollen in summer and autumn are paroxysmal nasal itching, sneezing, runny nose and stuffy nose, and some patients are accompanied by itchy eyes, jealousy and tears. This symptom occurs in the early autumn of each year, lasts for 65,438+0 to 3 months, and relieves in 65,438+00 months.

Allergic rhinitis in autumn is also called hay fever. Many people don't understand this. They don't think they have been exposed to pollen. Why are they allergic? In fact, pollen is spread by the wind, which is a process of increasing the depth of pollen in the air in a large area throughout the region. This process will last about two months, and most people's allergic symptoms will gradually ease or disappear after the National Day.

Let's take a look at the allergic symptoms in August and September to let you know that you are allergic:

Itching and sneezing is the first pass for air to enter the body. Inflammatory mediators such as histamine caused by pollen are released into the nasal mucosa, causing nasal itching and sneezing. Usually there are more than 5 sneezes in one attack, and patients with severe allergic rhinitis sneeze nearly 100 times a day.

The nasal mucosa with a runny nose removes pollen by secreting mucus to protect the body from the stimulation of pollen.

Nasal congestion, headache Most patients with pollen allergy have nasal congestion, especially at night. Because sneezing can cause headaches and sore throats.

Itchy eyes, tears, nasal pollen through the nasolacrimal duct or directly into the eyes cause conjunctivitis. It is characterized by hyperemia, increased secretion, severe itchy eyes and conjunctival edema.

Seasonal allergic rhinitis is a common disease, with a high incidence in the general population. At present, there is no epidemiological data of seasonal rhinitis in the general population in China. However, a survey based on skin tests in the United States shows that about 40-50 million people have allergic problems, of which 39.5 million people suffer from seasonal allergic rhinitis. Most allergic rhinitis in summer and autumn in America is caused by ragweed pollen. In the pollen pollination season, each ragweed has accumulated hundreds of millions of pollen, and in some areas, it produces more than ten tons of pollen per square kilometer. These pollen were scattered in the air with the wind, which caused allergic symptoms in sensitive person. The main allergenic pollen in summer and autumn in northern China is Artemisia, Humulus and Chenopodium. These plants are not ornamental flowers, but weeds such as ragweed, which grow in suburbs, mountains, rivers, roadsides and wasteland, and have the characteristics of tenacious vitality, small flowers and large pollen yield. The spread of pollen is closely related to climate factors. In windy and dry weather, the pollen concentration in the air is high, and the symptoms of patients are heavier, while in rainy and humid weather, the pollen concentration is low, and the symptoms of patients are lighter.

Seasonal allergic rhinitis is not a serious illness, but it is a chronic disease with high incidence. At least tens of millions of patients in China suffer from this disease. Once the disease breaks out, it will recur year after year, seriously affecting the quality of life and daily work. The therapeutic drugs that must be used every day also increase the medical burden of families and governments. Most notably, some patients can gradually develop seasonal asthma. In recent years, the Allergy Department of Peking Union Medical College Hospital has completed a large sample of hay fever patients in summer and autumn. The results showed that 1096 patients with allergic rhinitis caused by pollen in summer and autumn, 53% were complicated with seasonal asthma. Among them, 37% will develop into seasonal asthma within 5 years after the onset of rhinitis, and 47% will develop into seasonal asthma within 9 years. Very few patients can develop pollen-induced asthma in summer and autumn 20 ~ 30 years after the onset of rhinitis. 18% patients develop rhinitis and asthma for the first time in the same year.

Asthma induced by pollen in summer and autumn is often concentrated in autumn every year, starting from the middle and late August and continuing until the beginning of 10. The main clinical symptoms are paroxysmal cough, shortness of breath and wheezing, which are aggravated when going upstairs and downstairs or during activities. In severe cases, people can't sleep on their backs at night, and even need intravenous aminophylline or hormone treatment in an emergency. Among the 20 cases of pollinosis1/kloc-0 in summer and autumn, 42% need oral antiasthmatic drugs, 42% have symptoms of lying down at night, and 16% need emergency infusion treatment.

At present, not all clinicians know that pollen can cause severe asthma in summer and autumn. In this season, patients with frequent asthma attacks are mostly diagnosed as infectious asthma and receive a lot of antibiotic treatment. Repeated intravenous infusion of large doses of antibiotics and corticosteroids will bring many unnecessary medical risks to patients. In fact, the natural process from seasonal allergic rhinitis to asthma can be intervened by immunotherapy.

Kangminyuan Allergic Probiotics Immunity Intervenes Allergen Stimulation such as Pollen. Kangminyuan Allergic Probiotics developed by Professor Wang Zhiyao from national cheng kung university Allergy and Clinical Immunology Research Center in Taiwan Province can reduce allergen-specific antibody IGE on immune cells. The reason why pollen allergy recurs in a fixed place every year is because the spread cycle of pollen is fixed. When pollen began to spread, it was spread by the wind, so some people said that I had never been exposed to pollen. Why is pollen allergic? There is a lot of pollen in the air during the pollen transmission. If you are allergic to pollen, there will be specific IGE antibodies on your immune cell wall. When these antibodies combine with pollen, they will form antigen antibodies, thus sensitizing, so your allergic rhinitis will recur. With the increasing concentration of pollen, the symptoms of allergic rhinitis will be aggravated, and allergic cough may appear in severe cases. Even asthma, July, August and September are the high incidence of allergic conjunctivitis, which is also caused by pollen allergy. Therefore, reducing the allergen IGE antibody on immunoglobulin is a very important immune intervention therapy for pollen allergic rhinitis.

Pollen is an inhaled allergen, which exists in the air. It is of course best to avoid allergens, but it is almost impossible to isolate air. In addition to taking some protective measures as far as possible (such as going out as little as possible in spring or wearing masks or even scarves on your head), there are also some allergic patients who have been carrying some commonly used anti-allergic drugs with them for many years, such as cismin and chlorpheniramine. ), passive prevention is not as good as active change. For anti-allergy, we should also start with adjusting our own physique. At this time, it is particularly important to use the anti-allergic probiotic Kangmin source in advance, adjust the allergic constitution and remove the allergic antibody IgE stored on the cell membrane for a long time!

Many patients with autoimmune diseases are faced with a dilemma: most of these diseases are chronic and need long-term treatment, and the most effective treatment methods usually have certain risks or adverse side effects. In 2002, the United States Joint Committee on Autoimmune Diseases put forward a grand plan to study autoimmune diseases. There is a sentence in this research plan: the mechanism of regulatory T cells regulating immune response is very complicated. If we can regulate this mechanism, we can prevent or treat autoimmune diseases. Kangminyuan anti-allergic probiotics developed by Professor Wang Zhiyao from national cheng kung university National Center for Allergy and Clinical Immunity in Taiwan Province can enhance TH 1 immune response, regulate TH2 immune response which is overreacted due to allergy, improve anti-allergic ability and adjust allergic constitution. The use of anti-allergic probiotics can stimulate the production of regulatory T cells, and then regulate the immune response. Scientists have successfully used probiotics to prevent autoimmune diseases in animal experiments.

The World Health Organization pointed out in the guidance document of immunotherapy for allergic diseases that specific immunotherapy is the only way to stop the natural process of allergic diseases at present. Therefore, patients with severe allergic rhinitis induced by pollen in summer and autumn should start specific immunotherapy as soon as possible to prevent the development of asthma. For asthma patients, specific immunotherapy should be actively carried out to prevent asthma from getting worse.
