Study Notes
Allergies Increasing?
- Research indicates a rise in allergy occurrences globally.
- Factors contributing to this increase include urbanization, changes in lifestyle, diet, and environment.
Hygiene Hypothesis
- Increased cleanliness and decreased exposure to diverse microbes, particularly in early childhood, may contribute to amplified allergic reactions. This is the hygiene hypothesis.
- Reduced exposure to beneficial bacteria in the microbiome during infancy could play a role.
### Global Society & Allergies
- People migrating to different environments may experience heightened allergy rates due to genetic predisposition and environmental mismatch.
### Common Allergies
- Food allergies are prevalent, with peanuts a common example.
- Respiratory allergies, especially pollen allergies, are the most widespread, affecting around 400 million people globally.
- Australia has a high incidence of allergies, particularly in infants, with one in ten infants exhibiting a food or respiratory allergy.
Australia & Allergies: Vitamin D & the Jumping Jack Ant
- Vitamin D deficiency, potentially related to reduced sunlight exposure, may be linked to higher allergy rates in Australia.
- A study suggested a connection between vitamin D deficiency and peanut allergies.
- Allergies to the "Jumping Jack" ant, a venomous ant, are common in southern Australian states.
Awareness & Allergy Severity
- Increased awareness of allergies contributes to higher reporting rates.
- Allergies are becoming more common and severe.
Living with Allergies
- Mia, a US resident, lives with over 50 food allergies, resulting in significant daily challenges and fear.
- She emphasizes the impact of allergies on social life, food choices, and mental health.
Managing Allergies: Current Approaches
- Adrenaline-based treatments, such as EpiPens, are recommended to manage allergic reactions.
- Avoiding the triggering allergen is crucial.
- Research is underway to develop new and effective treatments beyond avoidance.
Peanut Butter Therapy & Immunotherapy
- Australian researchers are conducting trials to use peanut butter therapy for infants with peanut allergies.
- This immunotherapy gradually introduces small doses of peanut powder to the infant to desensitize the immune system.
- The therapy shows promising results but must be carefully monitored; self-administration is not recommended.
