What are the symptoms and hazards of dust mite allergic rhinitis?

Because of the change of seasons, many people's allergies begin to recur, not only skin allergies, but also allergic rhinitis. Most patients with allergic rhinitis are allergic to mites, dust, and catkins, which can cause allergic rhinitis. Dust mite allergic rhinitis will cause symptoms of nasal congestion, sneezing, and runny nose. Long-term illness will not only cause nasal congestion, but may also cause sinusitis, throat inflammation, asthma and many other complications.

symptom

1. Itchy nose and continuous sneezing: There are often several paroxysmal attacks every day, followed by nasal congestion and runny nose, especially in the morning and at night. Nasal itching occurs in most patients, and sometimes itching occurs on the outside of the nose, soft palate, face, and external auditory canal. Eye itching is more obvious in seasonal rhinitis.

2. Nasal congestion: The severity varies, and it may be unilateral or bilateral, intermittent or continuous, or alternating.

3. A lot of clear nasal discharge: When the acute reaction tends to weaken or disappear, the discharge may decrease or become thicker. If secondary infection occurs, it may become a mucopurulent discharge.

4. Olfactory disorder: If it is caused by mucosal edema or nasal congestion, it is usually temporary. Those caused by persistent edema of the mucosa leading to atrophy of the olfactory nerve are mostly persistent.

harm

Allergic rhinitis is not just about runny nose, sneezing and nasal congestion. If it is delayed or treated improperly, it will cause many complications, such as asthma, sinusitis, pharyngitis, etc. So, what are the dangers of allergic rhinitis?

Mild allergic rhinitis has no major impact on the patient's life, but moderate to severe allergic rhinitis has interfered with the patient's life, resulting in a decline in quality of life, affecting sleep, reduced work efficiency, poor academic performance, and entertainment, causing great distress to the patient. The symptoms of seasonal allergic rhinitis are more severe and occur at fixed seasons every year, making patients miserable.

treat

Desensitization therapy is also called specific immunotherapy or hyposensitization therapy. In 1997, based on years of understanding of the mechanism of specific immunotherapy and its clinical efficacy, WHO proposed a new term, specific allergy vaccination (SAV).

SAV is a method of clinically identifying the allergens of patients with allergic diseases, making the allergens into allergen extracts and preparing them into preparations of various concentrations. The allergens are repeatedly injected or exposed to the patients through other routes of administration, with the dosage increasing from small to large and the concentration increasing from low to high, thereby improving the patient's tolerance to the allergen. When the patient is exposed to the allergen again, allergic symptoms will no longer occur or will be alleviated.
