PREVALENCE of FOOD Allergy In ADULT PATIENTS of SERVICE Allergy and CLINICAL Immunology – Centro Medico Nacional Siglo XXI - IMSS Mexico DF

Background:

Food allergy affects 3 to 4% of the adult population, mainly crustaceans, tree nuts, fish, rosaceae.  In most cases, this type I hypersensitivity response. Foods involved in the case of adults are: shellfish, nuts, peanuts and fish. Fruits and vegetables can also cause hypersensitivity reactions, but its occurrence is rare.  The clinical picture included, urticaria, rhinoconjunctivitis, asthma, angioedema and anaphylactic shock. The diagnosis is made with skin prick tests corroborated and / or specific IgE, in addition to the challenge test double-blind, placebo controlled.

 OBJECTIVE .-

To determine the prevalence of food allergy in adult patients of the Allergy & Clinical Immunology

Methods:

-          We included 24 patients with a history of hypersensitivity to food of 600 who attended the service at 1-year study

-          Was performed to Prick Prick all patients who reported food hypersensitivity

Results:

-          22 female patients and 2 male

-          15 (62.5%) patients with hypersensitivity to Rosaceae, 3 (12.5%) with seafood allergy, 2 (8.33%) to nuts, 2 (8.33%) to pork and 2 (8.33% ) to milk derivates.

-          Hypersensitivity to the Rosaceae (62.5%); apple (93.3%), peach (73.3%), Strawberry (53.3%), Pear (46.6%), Kiwi (33.3%) and avocado, melon, plum (20% each).

-          Blue Fish (12.5%): Salmon (100%), Tilapia, Red Snapper (66.6% each), shrimp (33.3%).

-          Nuts (8.33%): Peanut Butter (100%), almond and walnut (50% each)

-          Pork (8.33%)

-          Milk derivates (8.33%): Cheese Manchego (100%) and Cream (50%)

Conclusions:

The prevalence of food allergies in adults in our hospital was 24 patients (4%) at 1 year of study, which is similar to the frequency of this pathology in the adult population, with foods that cause this disease in our department are referred as a cause in the published literature. To all of our patients started the elimination diet, with good results.
