Brief description of the etiology of rhinitis

As we all know, rhinitis is one of the most common diseases in our lives. The disease is less damaging to the human body, but often lasts longer, thus seriously affecting the quality of our work. Well, fully understand the cause of rhinitis, put an end to rhinitis, improve our quality of sleep and quality of work, has become the focus of everyone's attention.

1. virus infection
Virus infection is the primary cause, or in the virus infection based on secondary bacterial infection. Known to have more than 100 kinds of viruses can cause the disease, the most common is the rhinovirus, followed by influenza and parainfluenza virus, adenovirus, coronavirus, coxsackievirus and mucus and paraneoplastic virus. Virus transmission is mainly through the respiratory inhalation, followed by contaminated body or food into the body.
2. Genetic factors
There is a family history of allergic disease susceptible to the disease. Patient family members have more history of asthma, urticaria or drug allergy. In the past, this patient is an atopic individual, and its ability to produce IgE antibodies in vivo is higher than normal. But in recent years it was found that the incidence of twin and the general population was no significant difference.
3. nasal mucosal susceptibility
The susceptibility is due to the frequent stimulation of antigenic substances, but the degree of susceptibility is the number of mast cells, basophils, and the ability to release chemical mediators in nasal mucosa. It has been confirmed that the number of cells in the nasal mucosa of patients with allergic rhinitis is not only higher than normal, but also has a strong ability to release chemical mediators.
4. Antigenic substances
The antigenic substances that stimulate the body to produce IgE antibodies are called allergens. The allergen material once again into the nasal mucosa, with the corresponding IgE and cause allergic reactions. Cause the disease of the allergen according to its way into the human body is divided into two categories of inhalation and food.
(1) Inhalation allergen ① pollen is not all plant pollen can cause disease, only those pollen large, wide vegetation area, allergenic, and by the wind to spread the pollen is most likely to become allergens The Due to the differences in vegetation varieties, pollen with allergenicity in different areas is also different. ② fungi are widely distributed in nature, mainly in the soil and corrupt organic matter. The hyphae and spores are allergenic, but with strong spores.
(2) ingestion allergen refers to the digestive tract into the human body caused by nasal symptoms of allergen substances. Its role in the nasal mucosa is very complex, it is still not clear. Milk, eggs, fish and shrimp, meat, fruit, and even some vegetables can become allergens.
