Allergies to animals

This type of allergy distributed very widely and it can significantly degrade over its other manifestations. Pets are one of the strongest sources of allergens. Unlike what is commonly spoken, let us say that animals do not produce allergens - just wool is their excellent container.

Examples of animal allergens:

* Saliva (dogs, cats, horses, etc.)
* Urine (cats, dogs, small laboratory animals)
* Serum (of blood)
* Horny flakes (desquamated skin)
* Epithelium (desquamated skin)
* Excrement (parrots, pigeons and others)

The impact on the patient's allergy occurs when inhaled dust. Most frequent allergic to cats, but the most severe forms marked with allergies to horses and small rodents.

Everyone knows that cats are spending too much time on workaround. In doing so, they leave a large number of allergic saliva in your hair, saliva and then spread everywhere. Furthermore, when workaround cats scatters in the ambient air entire cloud of tiny drops saliva - they are literally "dispensers allergies!

In patients with allergic to dogs, she noted on any of their breed. Short-haired dogs with the same allergens as long-haired. Allergy birds are often indirect nature: develop sensitization not to peryam, and by parasitic mites in their mass.

Allergy reaction to dust

The number of dust in the house varies widely - depending on the location of the house, climate, time of year. Thus, in the rural house dust smaller than the apartment citizenship, and in the same house there is a difference between the number of bathroom and bedroom .

Invariably, only that any Web-dust - a comprehensive set of allergens, chief among them the house dust mites.

House dust mites

Pliers (Acarida) - tiny arthropods (like spiders), invisible naked eye diameter of the body - about 0.3 mm).
Two types of ticks found in house dust, can cause allergies: Dermatophagoides pteronyssinus and Dermatophagoides farinae.
These mites feed mailed desquamated horny layer of human skin, which is the largest part of house dust.

Pliers found in beds and bedding (pillows, mattresses, blankets, etc.) - where people lose the largest number of horns scales in friction skin during sleep. However, only the horns flakes that mites are not enough. They live in symbiosis with mold microscopic fungi living in a mattress.

You will be interested to know that in patients with sensitization to mites is also allergic to their excrement, which by their nature are ideal allergens. In bed more mites than on the floor in the bedroom. One gram of dust from the mattress can contain from 200 to 15000 mites!

The body of a sleeping person can harden up to 20-30 ° C and further create humidity - ideal conditions for life mites, and mold, in which they live in symbiosis, which is fed.

Symptoms

Allergy home dust (actually, for ticks) are most often manifests itself in the form of asthma and rhinitis, rarely - conjunctivitis.

Attack begins when the patient wakes up.

The symptoms observed throughout the year, but patients feel worse in autumn and winter - when the humidity higher.

Classification of Allergy Diseases

1) diseases associated with immediate response hyper sensibility type:

* Anaphylactic shock;
* Bannister's disease edema;
* Urticaria;

2) diseases associated with slow-hyper sensibility reaction type:

* Fixed drugs stomatitis;
* Common toxic-allergic stomatitis (catarrhal, catarrhal-bleeding, erosion-ulcerous, German-directly-necrotic stomatitis, cheilitis, glossitis, gingivitis);

3) systemic toxic-allergic diseases:

* Disease Layela;
* Many shapes exudative erythema;
* Stevens-Johnson syndrome;
* Chronic recrudescent thrush;
* Behçet's syndrome;
* Sjögren's sicca [Mikulicz-Sjögren] syndrome.

Allergic diseases among children is now widespread, constantly increasing the number and severity of the current. This is, apparently, pollution emission, waste industry, the emergence in the home of many plastics, dyes and other substances that are allergens, and hence contribute to the spread of allergic diseases. The widespread and uncontrolled use of drugs also leads to an increase in allergic reactions. Increased sensitivity to the drug substance is often caused by an unjustified use of multiple drugs, uncontrolled receiving antibiotics, lack of knowledge physicians pharmacokinetics of the drug. In the occurrence of allergic diseases play a role of influence of climatic factors, heredity, general pathology of power, etc.

So, allergies - is pathologically increased and perverse reaction of the organism to certain substances antigenic nature, which have normal individuals do not cause painful events. An important role in the development of allergies is as nervous, endocrine systems, alimentary canal diseases, etc. The cause allergies may be different substances that are entering the body, causing the immune response humoral or cell type.
