An Overview of Anaphylaxis

Anaphylaxis is a severe allergic reaction caused by the immune system’s hypersensitivity to a trigger, such as food, medication, or an insect sting. Anaphylaxis symptoms can develop suddenly and worsen rapidly, making it crucial to recognize the signs and seek prompt medical attention.

Triggers and Symptoms of Anaphylaxis

Common Food Allergies & Cross-Contaminants

Foods are one of the most common triggers for anaphylaxis. Some typical food allergens include nuts, milk, fish, shellfish, eggs, and fruits. Cross-contamination can also cause anaphylactic reactions in people with very severe allergies. For example, a person allergic to peanuts may experience anaphylaxis after consuming a food item that was prepared using the same utensils or equipment as a peanut-containing product.

Signs & Symptoms of Anaphylactic Shock

Anaphylactic shock is a severe and potentially fatal form of anaphylaxis. It occurs when the body’s immune system releases a large amount of histamine and other chemicals into the bloodstream, causing widespread inflammation and dilation of blood vessels. As a result, blood pressure drops, blood flow to vital organs decreases, and oxygen delivery to the body’s tissues is compromised. The symptoms of anaphylactic shock can include trouble breathing, a rash or hives, confusion, collapsing, nausea, or vomiting. Swelling of the lips, face, tongue, or neck is also common during these reactions.

Common Outdoor Allergens for Anaphylaxis Sufferers

Inhalant Allergens

Inhalant allergens, such as pollen, dust mites, and mold, can also trigger anaphylaxis in susceptible individuals. These allergens can cause a mild allergic reaction through inhalation or skin contact. Inhalant allergens are typically airborne.

Medication Allergies

Some medications, like antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs), can cause anaphylaxis in sensitive individuals. It is crucial to inform healthcare providers of any known medication allergies to avoid potential reactions.

Insect Sting Allergy

Insect stings, particularly from wasps and bees, can trigger anaphylaxis in some people. Those with a known insect sting allergy should take precautions to avoid stings and carry an epinephrine autoinjector for emergency self-treatment.

Anaphylaxis Triggers: Identifying the Key Risk Factors — Understanding Anaphylaxis: Common Risk Factors to Look Out For

Risk Factors for Anaphylaxis

Several factors, including a family history of allergies, a previous anaphylactic reaction, and certain medical conditions like asthma and atopic dermatitis, can increase the risk of developing anaphylaxis. Individuals with a weakened immune system or a history of autoimmune diseases may also be at higher risk for anaphylaxis. Understanding these risk factors, along with being aware of the 4 stages of anaphylaxis, empowers individuals and healthcare providers to develop effective strategies for prevention and management of anaphylactic reactions.

Treatment Options Available for Anaphylaxis

Antihistamines

Antihistamines are medications that help alleviate allergy symptoms by blocking the effects of histamine, a chemical released during an allergic reaction. They can relieve mild to moderate symptoms but are ineffective in treating anaphylaxis or the underlying cause of allergies.

Epinephrine Injections

Epinephrine (adrenaline) injections are the first-line treatment for anaphylaxis. They work by narrowing blood vessels and opening airways, helping to reverse severe symptoms of anaphylaxis, including life-threatening situations. Common types of adrenaline auto-injectors include EpiPen, Jext, and Emerade.

Oral Corticosteroids

Oral corticosteroids, such as prednisone, can help reduce inflammation and improve breathing in individuals experiencing anaphylaxis. They are typically prescribed for short-term use and are not a substitute for epinephrine injections.

Bronchodilators

Bronchodilators, such as albuterol, can help relax the muscles around the airways, making it easier to breathe during an anaphylactic reaction. They are often used in combination with other treatments, such as epinephrine injections and corticosteroids.

Immunotherapies

Immunotherapy, also known as allergy shots or desensitization, involves the gradual introduction of small amounts of an allergen to help the body build tolerance. This treatment can be effective in reducing the severity of allergic reactions, including anaphylaxis, over time.

Referral to Allergist

A referral to an allergist is often necessary for individuals who have experienced anaphylaxis or are at high risk. Allergists can help identify specific triggers, develop a personalized treatment plan, and provide guidance on managing allergies and avoiding anaphylactic reactions.

Intravenous Infusions

In some cases, intravenous (IV) infusions may be necessary during an anaphylactic reaction. This treatment involves administering fluids and medications directly into the bloodstream to help stabilize blood pressure, restore circulation, and provide necessary nutrients. IV infusions are typically administered in a hospital setting under the supervision of medical professionals.

Antibiotic Therapy

If an anaphylactic reaction is caused by a medication allergy, such as an antibiotic, discontinuing the medication and switching to a different antibiotic may be necessary. Your healthcare provider will help determine the best course of action and prescribe an alternative medication if needed.

Rescue Inhalers and Nebulizers

Rescue inhalers and nebulizers can provide temporary relief from breathing difficulties during an anaphylactic reaction. These devices deliver medication directly to the airways, helping to open them up and improve airflow. While they can help alleviate symptoms, they should not be used as a substitute for epinephrine injections in treating anaphylaxis.

Tips to Help Avoid Anaphylactic Reactions

Identify triggers: Work with an allergist to identify the specific allergens causing anaphylaxis.
Avoid triggers: Once triggers are identified, take steps to avoid exposure. This may include removing allergenic foods from your diet, avoiding outdoor activities during high pollen counts, or using insect repellent to prevent insect stings.
Carry adrenaline auto-injectors: Always carry two in-date adrenaline auto-injectors and know how to use them correctly.
Wear medical identification: Wearing a medical ID bracelet or necklace can alert others to your allergy in case of an emergency.
Inform others: Make sure friends, family, and coworkers are aware of your allergy and know what to do in case of an emergency.
