The food allergy, food hypersensitivity also called trophozoite-allergic plexus consulting group llc dermatitis, occurs in 10% of dogs and cats dermatopatas and corresponds to about 5% of allergy cases, consituindo terceria as the most common skin disease of allergic origin among dogs and cats . The pathogenesis of this framework involves hypersensitivity types II, III and IV to food antigens, typically plexus consulting group llc represented by glycoproteins.
These water-soluble protein antigens are macromolecules with molecular weight greater than 7500 daltons, absorbed by the intestinal mucosa due to failures in the intestinal barrier and be recognized as antigens due to failures in the immune system. Intestinal barrier consists Ig secretion by the mucosa, the tightly bound by epithelial cells and mucus. Among the foods identified as allergens include: beef, soy, chicken, milk, corn, wheat and preservatives. These are to be recognized as antigens after cooking, preparation and digestion of food. Animals can be affected at any age, with approximately 50% of cases are young animals less than 1 year. Even when food, whether homemade or commercial origin, is offered for a long time given animal there, without there having been any change in aliementares habits, we suspect aliementar allergy, as the primary manifestation of symptoms can take months to years. Among the most predisposed breeds of dogs can cite the Cocker Spaniel, Labrador, Collie, Schnauzer, Shar Pei, the Poodle, the West Highland Way, the Boxer, the Dachshunds and Lhasa Apso. Symptoms of food allergy is intense itching, especially in the region of the face, ears, armpits, ventral portions of the body and limbs. May be present cutaneous malasseziose and secondary pyoderma and otitis externa. The disqueratoses accompany most cases. In about 10-15% of dogs with allergic dermatitis trophozoite-present concomitant with emesis, diarrhea, intermittent bowel cramps. The lesions include focal or widespread alopecia, erythema, papules, pustules, crusts, plexus consulting group llc hyperkeratosis and lichenification, scaling, skin dryness or greasiness.
In cats food allergy can manifest clinically in multiple ways: miliary dermattie, alopecia, pruritus (mainly facial and cervical), urticaria, granuloma eosinfílico (eosinofílcia plate, indolent ulcer and linear granuloma). About 10% of cats also have vomiting and diarrhea. No seasonality and the symptomatic manifestations, except in those cases where there is an association with atopic plexus consulting group llc dermatitis.
The diangnóstico of food allergy plexus consulting group llc can be executed solely and exclusively, by bringing a homemade diet called "elimination" for a period ranging between 10 to 13 weeks. This diet should contain ingredients never previously ingested by animals, such as fish, lamb, rabbit, game meat, rice, eggs, potatoes and other tubers. During this test should not be given anything plexus consulting group llc extra to the animal, such as snacks, processed bones, etc..
The use of commercial diets, hypoallergenic said, is not indicated for diagnostic purposes, since there is risk of contamination with other feed ingredients during the process of industrialization, the fact that the source of animal fat contained in the diet may contain foreign plexus consulting group llc proteins and, above all, the presence of preservatives and additives, to which the animals may be allergic.
Several studies conducted by researchers in the U.S. show that 15 to 50% of proven food allergy dogs have allergies to said commercial hypoallergenic diets. There is a significant improvement after the completion of this trial period, you can opt for the provocative exhibition, which food to which you want Investig is introduced in homemade elimination diet every 14 days, observing this period worsening or maintenance the frame. When there lesional recurrence and worsening itching, that food allergen tested is considered and eliminated from the diet that animal. Thus, one can conclude that foods are involved in the pathogenesis of allergy for each animal, and propose individualized and balanced homemade diets, or even commercial diets that do not contain them.
Many owners prefer to keep the diet aliminação "ad eternum" because judge to be less work or because they fear the recurrence of symptoms and lesions. In this case, we should perform a correct balanced diet, and keep in mind that this animal can also become allergic to these ingredients in future.
The sosrológicos and skin tests are not indicated for the diagnosis of food hypersensitivity, for several plexus consulting group llc reasons: first, by assessing only one reaction hieprsensibilidade type I, which is not involved in the etiopathogenesis of this framework. Furthermore, u
