What is Anaphylaxis?
Anaphylaxis is a severe allergic reaction triggered by the body's immune system.
Causes of Anaphylaxis
Immune System Overreaction: Anaphylaxis occurs when the immune system reacts excessively to a harmless substance, releasing chemicals like histamine.
Common Triggers
1. Insect Stings
• Most commonly caused by wasp and bee stings.
• Around 1 in 100 people may experience an allergic reaction.
• Did you know? Insect sting allergies are more common in adults than children.
2. Foods
• Peanuts are the leading cause, followed by nuts, milk, fish, shellfish, eggs, and certain fruits.
• Food-induced anaphylaxis accounts for a significant portion of emergency room visits.
• Fun Fact: Peanuts are not nuts but legumes!
3. Medicines
• Antibiotics (particularly penicillin-like), general anesthetics, and NSAIDs (e.g., ibuprofen, aspirin) can trigger anaphylaxis in some individuals.
• Adverse drug reactions are a common cause of anaphylaxis-related fatalities.
• Interesting Fact: Penicillin is one of the most common antibiotics associated with allergic reactions.
4. Contrast Agents
• Special dyes used in medical tests such as X-rays.
• Risk of anaphylaxis is less than 1 in 10,000.
• Allergic reactions to contrast agents can vary in severity, ranging from mild to life-threatening.
• Did you know? Contrast agents contain iodine, which can trigger reactions in susceptible individuals.
5. Rubber Latex
• Latex allergy affects less than 1 in 100 people.
• More common in certain professions and individuals with specific medical conditions.
• Healthcare workers are at increased risk due to frequent exposure to latex gloves and medical equipment.
• Fun Fact: Latex comes from the sap of the rubber tree, Hevea brasiliensis.
6. Idiopathic Anaphylaxis
• Sometimes, the trigger remains unknown despite thorough testing.
• Idiopathic anaphylaxis poses challenges in diagnosis and management, requiring close monitoring and ongoing evaluation.
• Curious Fact: Idiopathic means "of unknown cause" in medical terminology.
Treatment and Management
• Administered to narrow blood vessels, raise blood pressure, and open airways.
• Should be used immediately upon suspicion of anaphylaxis.
• Delay in adrenaline administration increases the risk of severe complications.
Positioning and Resuscitation
• Lying flat with legs raised, or on the left side for pregnant women.
• CPR if breathing or heart stops.
• Prompt intervention is crucial to prevent irreversible damage.
Hospital Admission
• Observation for 6 to 12 hours, even after administering adrenaline.
• Oxygen mask and intravenous fluids may be necessary.
• Close monitoring allows for timely detection of recurrent symptoms.
Follow-Up Care
• Attend follow-up appointments for further advice.
• Consider carrying an adrenaline auto-injector for emergency use.
• Education and preparedness are key in preventing future anaphylactic episodes.
• Interesting Fact: Anaphylaxis can occur even in individuals with no prior history of allergies.
Conclusion
Anaphylaxis requires prompt recognition and treatment. Understanding the causes and triggers can help individuals manage their condition effectively and reduce the risk of future episodes. If you suspect anaphylaxis, seek immediate medical assistance and follow up with healthcare professionals for ongoing support and guidance. Remember, early intervention saves lives.
