Food allergies can be transmitted from blood products to children in rare cases

Posted in: Medical News Today | Posted on: 07 April, 2015

In rare cases, children can develop anaphylactic allergies to previously tolerated foods after receiving blood products via transfusion, report the authors of a case study published in CMAJ (Canadian Medical Association Journal).

“People shouldn’t be overly concerned about passive transfer of allergy from blood products, says Dr. Julia Upton, The Hospital for Sick Children (SickKids), Toronto, Ontario. “This condition has an excellent prognosis and typically resolves within a few months.”

Conditions Treated

Allergy Shots

Allergy immunotherapy, also called “allergy shots,” is prescribed to modify the immune system’s response to allergens with the goal of minimizing and/or preventing an allergen initiated inflammatory response.
Allergy Drops & Tablets

Allergy drops, and tablets are two forms of sublingual immunotherapy that are injection-free alternatives to allergy shots. Both contain environmental allergen such as pollen, dust mites, molds, cat, or dog.
Asthma

Asthma is a chronic inflammatory lung condition that usually starts in childhood but can occur at any age. Allergists are considered the experts in asthma and diagnose this condition by history, exam and breathing tests of the airways.
Allergy & Sinus

Allergic rhinitis is one of the most common chronic conditions in the US. Individuals with allergic rhinitis develop allergy antibodies (IgE) targeted against allergens including pollen, animal proteins, dust mites, mold, and insect droppings.
Food Allergy

Food allergy affects 5% of children and 4% of adults in the United States and is defined as an adverse health event that is immune mediated and occurs reproducibly. Individuals with IgE mediated food allergy develop allergy antibodies (IgE) targeted against food allergens.
Allergic Rashes

Atopic dermatitis is a chronic, relapsing inflammatory skin disorder that usually starts at age < 5 years. It is characterized by itchy skin that becomes inflamed with scratching. For this reason, atopic dermatitis is known as the “itch that rashes.”
