Probiotics and Diet Modifications Are Not Recommended for Managing Eczema and Dust Mite Allergy in a 5-Year-Old
The consumption of Vaalia immunity booster yogurt, Biome Kids probiotics, eggs, and various seeds (hemp, chia, flaxseeds, pumpkin seeds) is not recommended as an effective treatment for eczema and dust mite allergy in a 5-year-old child with high IgE levels. 1
Current Evidence on Dietary Interventions for Eczema
- The use of probiotics/prebiotics for the treatment of patients with established atopic dermatitis is not recommended due to inconsistent evidence 1
- Food elimination diets based solely on the findings of food allergy test results are not recommended for the management of atopic dermatitis 1
- There is inconsistent to no evidence to recommend the use of supplements such as fish oils, evening primrose oil, borage oil, multivitamin supplements, zinc, vitamin D, vitamin E, vitamin B12 and B6 for the treatment of atopic dermatitis 1
- Diet diversity during infancy may be associated with reduced allergy outcomes, but additional studies are required to define more clearly the role of diet diversity and diet patterns 1
Management of Eczema in Children with Dust Mite Allergy
- There is limited evidence to support the routine use of house dust mite covers to treat patients with atopic dermatitis who are sensitized to dust mites 1
- Patients at risk for developing food allergy do not need to limit exposure to potential nonfood allergens (e.g., dust mites or pollen) 1
- Children younger than 5 years with moderate-to-severe atopic dermatitis should be considered for food allergy evaluation for cow's milk, egg, peanut, wheat, and soy only if:
- The child has persistent atopic dermatitis despite optimized management and topical therapy, or
- The child has a reliable history of an immediate reaction after ingestion of a specific food 1
Recommended Approach for This Patient
Focus on standard eczema treatment first:
- Continued use of either topical corticosteroids (1-2× per week) or topical calcineurin inhibitors (2-3× per week) after disease stabilization, to previously involved skin, is recommended to reduce subsequent flares or relapses 1
Consider proper allergy evaluation:
- If the child has persistent atopic dermatitis despite optimized management, consider formal allergy testing rather than trying unproven dietary interventions 1
- Because false-positive tests for food allergy are common, care should be taken to ensure that children are clinically allergic and not just sensitized to a food before dietary removal 1
Environmental modifications:
- General recommendations are to avoid known mechanical and chemical irritants 1
- In patients who are sensitized to house dust mite and whose atopic dermatitis is uncontrolled, the clinician could consider recommending a house dust mite cover for the pillow and mattress, though evidence for this is limited 1
Important Caveats and Pitfalls
- Eliminating foods without proper allergy testing can lead to nutritional deficiencies and poor weight gain in children 2
- Despite high IgE levels to house dust mite, immunotherapy may improve rhinitis symptoms but has not shown consistent benefit for eczema 2
- The World Allergy Organization determined that while probiotics may have some benefit for prevention of eczema, they do not show benefit for food allergy prevention 1
- Dietary interventions should only be considered when a specific diagnosis of food allergy has been made through proper testing, not based on IgE levels alone 3
- Systematic reviews have found little good quality evidence to support the use of exclusion diets in atopic eczema in unselected patients 4
Rather than focusing on unproven dietary supplements and probiotics, management should prioritize proper skin care, appropriate use of anti-inflammatory medications, identification of true food allergies through proper testing, and targeted environmental modifications when indicated.
