Definition and Classification of Anaphylaxis
Anaphylaxis is when the body overreacts to an allergen. It leads to severe symptoms that affect many organs. To understand it better, anaphylaxis is put into groups based on triggers and symptoms.
Mast cells and basophils are key in anaphylaxis’s development. They release substances that worsen the reaction, like histamine. These cells can be found all over the body and in the blood.
Anaphylaxis types show doctors what caused it, so they can treat patients right. It looks at the kind of trigger, how it enters the body, and the symptoms. For example:
- Food-induced anaphylaxis: Triggered by eating allergy-causing foods like peanuts or dairy.
- Drug-induced anaphylaxis: Caused by medications, such as antibiotics or NSAIDs.
- Insect sting-induced anaphylaxis: Happens after getting stung by bees or wasps.
- Exercise-induced anaphylaxis: Can be triggered by working out combined with certain foods.
- Idiopathic anaphylaxis: When the trigger can’t be found, even with tests.
Mast Cells in Anaphylaxis
Mast cells are crucial in starting and spreading anaphylaxis. They release chemicals like histamine when they come in contact with allergens. This makes blood vessels leak and causes a drop in blood pressure.
Understanding anaphylaxis helps doctors give the right treatment. This includes using epinephrine to stop severe reactions. It’s also important for patients to know their triggers, avoid them, and have epinephrine ready for emergencies.
Epidemiology of Anaphylaxis
Anaphylaxis is a serious allergic reaction that can happen to anyone. It’s not very uncommon. The number of cases can differ from place to place. In the Western world, more people seem to be affected every year. Anaphylaxis can cause death, but most people survive it. Yet, older people or those with other health problems might be at a bigger risk.
People with a history of allergies, like asthma or food allergies, are more at risk. Also, being around substances you’re allergic to raises your chances of having a reaction. Knowing these risk factors is key to keeping anaphylaxis at bay.
Epidemiological Data
Experts collect and study data to learn more about anaphylaxis’s spread and effects. This info helps us understand how anaphylaxis affects people in different groups.
| Country/Region | Prevalence | Mortality |
|---|---|---|
| United States | 1.6%-5.1% of the population* | 0.5-2 deaths per million population per year* |
| Australia | 2.2%-2.7% of the population* | 0.3-0.5 deaths per million population per year* |

*Note: Prevalence and mortality rates can change due to differences in how studies are done and the people in them.
Researchers and doctors need to keep studying anaphylaxis. This information helps set up ways to prevent it, make treatments easier to get, and lower the dangers anaphylaxis brings.
Clinical Manifestations of Anaphylaxis
Anaphylaxis causes a variety of symptoms affecting different parts of the body. The breathing system is often hit hard. You might find it hard to breathe, hear wheezing, or notice your throat swell. Other symptoms like low blood pressure and fainting could mean trouble in your heart and blood vessels. Skin problems, including hives or redness, and stomach issues like nausea, vomiting, and pain are also signs to watch for.
The breathing system is very fragile during anaphylaxis. Breathing issues, wheezing, and a swollen throat can make it extremely hard to breathe. related You might feel dizzy and have a pounding or weak heart. The skin can show signs too, like hives, which might itch. Sometimes, there are stomach problems, like feeling sick or having stomach pain. It’s crucial to remember that anaphylaxis affects people differently, so not everyone will have the same symptoms.
Respiratory Symptoms:
- Difficulty breathing
- Wheezing
- Throat swelling
Cardiovascular Symptoms:
- Low blood pressure
- Fainting
- Weak or rapid pulse
Cutaneous Manifestations:
- Hives
- Flushing
Gastrointestinal Symptoms:

Diagnosis of Anaphylaxis
The diagnosis of anaphylaxis relies on symptoms that appear quickly. It also looks at how several parts of the body react, like the heart and skin. Doctors start by asking about your medical history and doing a physical check-up.
Anaphylaxis shows itself through many symptoms. It can cause trouble breathing, a drop in blood pressure, and a skin rash. Other signs are feeling sick, throwing up, and stomach pain.
To be sure of the diagnosis, doctors might run some tests. These tests help find out what caused the reaction. They also back up the doctor’s initial diagnosis. Some tests include measuring tryptase levels in blood and doing a skin prick test.
- Measurement of serum tryptase levels: High tryptase levels can mean anaphylaxis happened.
- Skin prick test: Doctors put small amounts of allergens on your skin to check for reactions. This can show which substances are causing the problem.
- Specific IgE tests: These tests look for certain antibodies in your blood. They help pinpoint what’s triggering the allergic reaction.
By combining clinical signs with test results, doctors can clearly say it was anaphylaxis. Getting a fast and correct diagnosis is key. It helps start treatment quickly and avoids more severe reactions in the future.
Management and Treatment of Anaphylaxis
Anaphylaxis needs quick care for the best outcomes. Epinephrine is the top treatment and must be used right away. It helps by reversing the allergen’s effects, relaxing airways, and increasing blood flow.
Those at risk should always have an epi-pen. Knowing how to use it can save lives. Besides epinephrine, antihistamines and corticosteroids might help. They can reduce itching and inflammation and prevent symptoms from coming back. Take these drugs as your doctor says.
Supportive care is also crucial. This involves keeping the airway clear and possibly giving supplemental oxygen. It aims to stabilize the patient until they reach the hospital. Always get medical help after giving epinephrine, even if the person seems better.
Long-term, it’s important to avoid allergens. Keep a record of reactions and get tested by an allergist. Learn how to spot hidden allergens, read food labels, and carry epinephrine. This can prevent future allergic reactions.
