The development of allergic conditions is always a cause for concern among patients and physicians. Reactions, which are triggered as an immune response to a ‘threat’, can range from urticaria (itching) and angioedema (swelling) to anaphylaxis.

Last week, Twitter user Samuel Custódio, who went viral in 2022 when he reported being unable to unlock his cell phone using facial recognition due to angioedema after eating seafood, joked about the episode again, explaining his supposed reaction to Win a dinner at a. Season. the plate? Shrimp risotto.

Remember the state in 2022:

“Contacting a food structure, whether through skin, mucous membrane or inhalation, if the body perceives it as an ‘allergen’ and foreign, the immune system begins to produce antibodies against the protein of that food.” [chamada de IgE]generates the inflammatory process,” says allergist and immunologist Briana Nicoletti, MD, of Israelta Albert Einstein Hospital.

The severity of this process depends on how sensitive (allergic) the person is and whether they were previously inflamed (for some other reason), and it may also occur with foods that the person is already used to eating.

Conditions like Samuel’s, which cause disfiguring swelling of the mucous membranes, eyelids, lips, and tongue, are known as angioedema. According to Brianna, this swelling can last up to three days, and cause pain, tingling, and numbness at the site, with no residual damage.

According to Alemão Oswaldo Cruz Hospital Allergist and Immunologist Fabiana Mascarenhas, foods that often cause angioedema and allergic reactions are milk, eggs, wheat, fish and crustaceans. In addition to food, the reaction is also commonly associated with allergies to medications, insect bites, and contact (latex) agents.

Allergy-induced angioedema occurs in an inflammatory reaction to histamines, Fabiana explains, and is associated with immediate reactions (to a food or medication, for example).

Histamine causes dilation of blood vessels that causes hives when it occurs in the superficial layer of the skin. When it occurs in the deep dermis, it causes angioedema, which causes swelling and deformity.

When provoked by an allergic reaction to histamine, angioedema usually appears within the first hour after contact with the agent that would cause the allergy. Once appropriate treatment is provided, the condition quickly reverses.

Fabiana notes that hives and itching tend to be present in 90% of cases. Cutaneous manifestations may also include angioedema, but not in its entirety.

To treat cases of angioedema, Briana warns that it is first necessary to identify the causative agent and eliminate it from consumption.

In mild cases with severe manifestations, the condition can be reversed with the administration of antiallergic drugs.

More severe cases may require intervention in the emergency room, with intravenous medications and even the use of self-injected adrenaline, depending on the situation.

It is also essential to be aware of anaphylaxis, when more than one system is compromised due to an allergic reaction, adapting the approach according to the appearance.
