fungal allergy
Introduction
Introduction to fungal allergy Spores and hyphae of fungi can cause allergic reactions after entering the human body through various routes. Patients with idiosyncratic (atopic reactivity) (such as asthma, allergic rhinitis, atopic dermatitis, etc.) are more susceptible to fungal allergy. Allergies may also occur in long-term exposure or frequent exposure to normal people with a large number of special allergens due to occupational reasons. Clinically, the skin and respiratory tract are the main reactive organs, and the skin is characterized by allergic dermatitis, eczema, atopic dermatitis, urticaria, pruritus, pruritus, and sputum rash (which can be sweat-like, eczema-like, erysipelas-like, Polymorphous erythema, seborrheic dermatitis-like, psoriasis-like, pityriasis-like, and even erythrodermic, and sweat herpes are the most common; respiratory manifestations include asthma, allergic rhinitis, peasant lungs, etc. In addition, there are allergic reactions in the gastrointestinal tract and nervous system (such as periodic migraine). basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: Eczema Contact dermatitis Urticaria
Cause
Cause of fungal allergy
Cause:
Fungi, like other microorganisms, have a certain regularity in the occurrence of allergic reactions, but because of their large bacteria, the cell wall is rich in polysaccharides, has complex metabolic processes and enzyme systems, and potential antigenicity, so it is also associated with bacteria. Different viruses, its sensitization to the body is related to the following factors: 1 species, allergens such as Aspergillus, Alternaria, etc., susceptible to allergies; 2 spores are more antigenic than hyphae; 3 individuals Sensitive physique also plays an important role.
Prevention
Fungal allergy prevention
Usually pay attention to the correct prevention and treatment of fungal allergy. Shrimp, crab, shellfish and other seafood may cause fungal allergy, should be avoided as much as possible to avoid recurrence of symptoms, affect the effect of treatment, and must pay attention to avoid allergen stimulation, usually add exercise, relax body and mind to enhance immunity, There must be a significant improvement in allergies. If the physical condition is relatively poor, pay attention. Timely detection should also be treated in a timely manner. Treatment should first remove allergenic fungi, use antihistamines and symptomatic treatment, and severely use corticosteroids. Experts recommend Kangmei allergy kit to improve allergies and cure fungal allergies.
Complication
Fungal allergy complications Complications eczema contact dermatitis urticaria
Complications such as secondary bacterial or fungal corneal infection.
1, contact dermatitis: refers to skin contact with certain substances (such as jewelry, bracelets, sandals, cosmetics, etc.), local erythema, edema, itching pain, severe cases may have blisters, peeling and other phenomena.
2, eczema: local or whole body visible erythema, papules, blisters, erosion, exudation, crusting, scaling, pigmentation, severe itching, obvious exudation.
3, urticaria (wind group, rubella block): sudden and intense itching or burning sensation of the skin; the affected area quickly appears in varying sizes, limited block edema wheal, small to rice grain, up to the size of the palm, common for nails to coins Size, slightly above the surrounding skin.

Clinically, the skin and respiratory tract are the main reactive organs, and the skin is characterized by allergic dermatitis, eczema, atopic dermatitis, urticaria, pruritus, pruritus, and sputum rash (which can be sweat-like, eczema-like, erysipelas-like, Polymorphous erythema, seborrheic dermatitis-like, psoriasis-like, pityriasis-like, and even erythrodermic, and sweat herpes are the most common; respiratory manifestations include asthma, allergic rhinitis, peasant lungs, etc. The latter will be described in respiratory diseases, and it is omitted here, in addition to allergic reactions of the gastrointestinal tract and nervous system (such as periodic migraine).
Examine
Fungal allergy check
The most effective measure is to find allergic evoked factors and avoid contact with this substance, but it is not easy to find the pathogenic factors accurately among 20,000 different evoked factors, to detect the sensitization of a substance. In response, doctors need to do a variety of different skin tests, which is time-consuming and laborious, and because many sensitizing substances can not be completely avoided, such as drugs and insects can not be prevented.
Diagnosis
Diagnosis and identification of fungal allergy
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
It is mainly distinguished from allergic diseases caused by other causes.
1, the typical symptoms of allergic rhinitis are: First, paroxysmal continuous sneezing, each episode is generally no less than 5, and sometimes even more than a dozen, dozens, sneezing time often rises early, Falling asleep at night or aggravating with the seasons, severely occurs almost every day; second, a large amount of watery nose after sneezing; third is the blockage of the nasal cavity, the severity of each episode varies, can last for ten minutes or a few Ten minutes.
2, allergic asthma is more common in childhood, patients often have atopic physique allergic to certain substances, such as inhaling cold air, pollen, dust mites, etc.; eating fish and shrimp, milk, etc.; exposure to certain drugs, such as penicillin, etc. . When these allergens enter the patient's body, they pass through a series of reactions, causing mast cells or basophils to release sensitizing active substances, acting on the bronchi, causing extensive small airway stenosis and wheezing symptoms. If not treated in time, asthma can be fatal.
3, 1-3 weeks before the onset of allergic purpura often have a history of upper respiratory tract infection, and general malaise, fatigue, fever and loss of appetite, followed by skin purpura, accompanied by joint pain, abdominal pain, hematuria or black stool, etc. These symptoms are often misdiagnosed.
