What is Anaphylaxis?

Anaphylaxis is a severe, potentially life-threatening allergic reaction that occurs rapidly after exposure to an allergen. It is a medical emergency that requires immediate recognition and treatment. The term "anaphylaxis" comes from Greek words meaning "against protection" and describes the body's extreme overreaction to a substance that is normally harmless.

In anaphylaxis, the immune system releases a flood of chemicals, including histamine, from mast cells and basophils. These chemicals cause a cascade of effects throughout the body: blood vessels dilate and become leaky, causing a drop in blood pressure; airways constrict, making breathing difficult; and the skin, digestive system, and other organs react violently. This systemic response can escalate rapidly and become life-threatening within minutes.

Anaphylaxis is not a single pattern of symptoms but rather a syndrome that can involve multiple organ systems. The severity and combination of symptoms vary from person to person and even from one reaction to another in the same individual. Prompt administration of epinephrine (adrenaline) is the only treatment that can reverse these effects and save lives.

Common Causes of Anaphylaxis

Any substance that triggers an allergic reaction can potentially cause anaphylaxis in susceptible individuals. The most common triggers include:

Foods (Most Common Cause in Children and Increasingly in Adults)

• Peanuts and Tree Nuts: Among the most common causes of severe anaphylaxis
• Shellfish: Shrimp, crab, lobster, prawns
• Fish: Salmon, tuna, cod
• Milk: Cow's milk, especially in children
• Eggs: Particularly egg whites
• Wheat: Can cause severe reactions in some individuals
• Soy: More common in children
• Sesame: Increasingly recognised as a significant allergen
• Fruits: Though usually mild (oral allergy syndrome), some can trigger anaphylaxis

Medications

• Antibiotics: Penicillins, cephalosporins, sulfa drugs
• NSAIDs: Ibuprofen, naproxen, aspirin
• Anaesthetics: Both local and general anaesthetics
• Radiocontrast Media: Dyes used for CT scans and X-rays
• Chemotherapy Drugs: Platinum-based agents, taxanes
• Monoclonal Antibodies: Biologic therapies

Insect Stings

• Bees: Honeybees, bumblebees
• Wasps, Hornets, Yellow Jackets: Multiple stinging insects
• Fire Ants: Particularly in endemic areas

Other Triggers

• Latex: Natural rubber latex in gloves, medical devices, balloons
• Exercise-Induced Anaphylaxis: Triggered by physical activity, often in combination with specific foods (food-dependent, exercise-induced anaphylaxis)
• Idiopathic Anaphylaxis: No identifiable trigger despite thorough evaluation
• Occupational Exposures: Laboratory workers handling allergens, healthcare workers with latex allergy

Signs and Symptoms of Anaphylaxis

Anaphylaxis typically involves two or more organ systems and develops rapidly, usually within minutes to two hours after exposure. Early recognition is critical for survival.

Skin and Mucous Membranes (Present in 80–90% of cases): Hives, flushing, angioedema (swelling of eyes, lips, tongue, throat), generalised itching, warmth

Respiratory System (Present in 70% of cases):

• Upper Airway: Swelling of tongue, throat, or uvula; sensation of throat closing; hoarse voice; stridor
• Lower Airway: Difficulty breathing, wheezing, chest tightness, repetitive coughing

Cardiovascular System (Present in 45% of cases): Hypotension, dizziness, fainting, pale clammy skin, weak rapid pulse, shock; in severe cases cardiac arrest

Gastrointestinal System (Present in 40–45% of cases): Nausea, vomiting, abdominal cramping, diarrhoea

Neurological Symptoms: Anxiety or sense of impending doom, confusion, headache; rarely seizures

The "Rule of 2" for Recognising Anaphylaxis

Anaphylaxis is highly likely when any ONE of the following occurs within minutes to hours after exposure to a known or likely allergen:

1. Acute onset of illness involving skin/mucosal symptoms plus either respiratory compromise or reduced blood pressure/symptoms

2. Two or more of the following occurring rapidly: skin/mucosal involvement, respiratory compromise, reduced blood pressure/symptoms, persistent gastrointestinal symptoms

3. Reduced blood pressure after exposure to known allergen (children: low systolic for age; adults: systolic below 90 mmHg or 30% decrease from baseline)

Emergency Treatment of Anaphylaxis

Immediate Actions (The "ABC" Approach)

1. Epinephrine (Adrenaline) – First and Most Important Treatment

• Administer immediately; epinephrine is the only medication that can reverse anaphylaxis
• Route: Intramuscular injection into the mid-outer thigh
• Dosing: Adults >30 kg: 0.3 mg; Children 15–30 kg: 0.15 mg; Infants <15 kg: 0.1 mg
• Repeat after 5–15 minutes if no response
• Temporary side effects (anxiety, palpitations, tremor) indicate the medication is working

2. Call Emergency Services: In India dial 108 or local emergency number. Inform them: "Someone is having anaphylaxis and needs emergency medical help." Do not drive to hospital yourself.

3. Position the Patient:

• Breathing difficulties: Sit patient upright
• Shock symptoms: Lie flat with legs elevated
• Vomiting or unconscious: Recovery position (on side)
• Pregnant: Lie on left side
• Do NOT ask patient to stand or walk—can cause fatal "empty vein syndrome"

4. Remove Trigger if Possible: Remove stinger for insect stings; do not induce vomiting for food; stop infusion for medication.

Additional Measures (by Emergency Personnel): High-flow oxygen, IV fluids, nebulised bronchodilators, antihistamines (second-line, do not replace epinephrine), corticosteroids to prevent biphasic reactions.

Long-Term Management of Anaphylaxis Risk

• Epinephrine Auto-Injectors: Prescribe for all with history; carry two doses; regular training; check expiration dates
• Personalised Emergency Action Plan: Patient ID, allergens, signs of mild/severe reaction, epinephrine instructions, emergency contacts
• Medical Alert Identification: Bracelet, necklace, or card indicating anaphylaxis risk and triggers
• Trigger Avoidance Education: Food label reading, cross-contamination prevention, safe dining, medication alternatives, insect avoidance
• Immunotherapy: Venom immunotherapy for insect allergy; OIT for food allergies; drug desensitisation when needed
• Regular Follow-Up: Annual review, reassessment of triggers, practice with trainer devices

Biphasic Anaphylaxis

Biphasic anaphylaxis is recurrence of symptoms after initial improvement, typically 1–8 hours (sometimes up to 72 hours) later. It occurs in approximately 20% of cases, can be as or more severe than the initial reaction, and cannot be reliably predicted. Patients are observed in hospital for 4–6 hours or longer for this reason. Corticosteroids may reduce risk but do not eliminate it.

Anaphylaxis in Special Populations

• Children: Food allergy most common; weight-based epinephrine; schools need epinephrine and trained staff
• Pregnancy: Anaphylaxis can cause fetal distress; left lateral positioning essential; epinephrine safe for mother and fetus
• Elderly: Higher cardiovascular risk; medications (beta-blockers, ACE inhibitors) may complicate treatment; falls risk
• Patients with Asthma: Increased risk of severe respiratory involvement; well-controlled asthma essential

Anaphylaxis Mimics (Conditions That Can Look Like Anaphylaxis)

"Anaphylaxis is unpredictable but manageable. The key to survival is preparation: knowing your triggers, carrying epinephrine at all times, and having a clear action plan. Every patient at risk deserves comprehensive education and support to live confidently despite their allergy."
