Allergy Care: New Modalities and Holistic Approaches

Rising food allergies challenging for Asian healthcare

The prevalence of allergic diseases, such as asthma, allergic rhinoconjunctivitis, and atopic eczema, varies significantly worldwide. Studies, including the International Study of Asthma and Allergies in Childhood (ISAAC), have shown considerable increases in these conditions, particularly in children. Food allergies, especially among younger age groups, also exhibit heterogeneity in prevalence and triggers across Asia. Common allergens include cow milk, egg, and seafood, with patterns differing from other populations, possibly due to dietary differences. Rising incidence of food allergies poses significant healthcare challenges, necessitating comprehensive studies and regionally-relevant guidelines for diagnosis and treatment. Collaboration in research is crucial to address the increasing burden of food allergies in Asia effectively.

Treating food allergies with allergy-triggering foods

A clinical trial funded by the Natasha Allergy Research Foundation is showing promising results in treating food allergies in children. By gradually introducing small amounts of trigger foods under medical supervision, the trial aims to build up immunity and tolerance in allergic individuals. Early results suggest that this oral immunotherapy could be life-transforming for those with severe allergies, potentially allowing them to live without fear of fatal reactions. Participants like Thomas, who was previously allergic to peanuts, have experienced significant improvements, offering hope for a future where food allergies are no longer a concern. The full results of the trial are expected in 2027.

New drug option

A study led by Stanford School of Medicine suggests that the drug omalizumab can significantly reduce severe allergic responses in children with multiple food allergies. Published in the New England Journal of Medicine, the research indicates that regular use of omalizumab could protect individuals from life-threatening reactions, such as difficulty breathing, when exposed to small amounts of allergenic foods. This approach offers hope for those facing daily risks from accidental exposures, as it effectively mitigates allergic responses. Omalizumab, originally approved for allergic asthma and chronic hives, has now gained FDA approval for reducing the risk of allergic reactions to foods based on the study’s findings. Nonetheless, medications may have adverse effects and must be used under physician supervision.

Going natural to alleviate allergies and symptoms

Certain individuals prefer natural remedies due to concerns about the adverse effects and risks associated with synthetic drugs. Below are several natural remedies that may help alleviate allergy symptoms when used alongside medications
Acupuncture – While studies show mixed results, some find acupuncture beneficial for mild allergies.
Allergy-proofing your home- Keep windows closed, use air conditioning, and change clothes/shower after being outside to reduce pollen exposure.

HEPA filters – Though their effectiveness is debated, HEPA filters can capture allergens; use them in both air purifiers and vacuum cleaners.

Nasal washes – Use saline solutions in a neti pot to rinse sinuses, ensuring water safety by using distilled or filtered water.
Avoid outdoor activities- During peak pollen times avoid outdoor activities and wear protective gear during gardening or cleaning to minimize exposure.

Saline sprays – Over-the-counter saltwater sprays can clear nasal passages of irritants like pollen.
Supplements- Some supplements like butterbur, fermented red ginseng, and Tinospora cordifolia extract show promise in alleviating allergy symptoms, but caution is advised due to potential side effects.
