Prebiotics and probiotics: the prevention and reduction in severity of atopic dermatitis in children

Area of Science:

• Pediatric Allergy and Immunology
• Microbiome Research
• Nutritional Science

Background:

• Atopic dermatitis (AD) is a common inflammatory skin condition in infants.
• The role of gut microbiota and immune modulation in AD development is increasingly recognized.
• Prebiotics and probiotics are explored as potential interventions for immune-related conditions.

Purpose of the Study:

• To evaluate the efficacy of prebiotics and/or probiotics in preventing or reducing the severity of atopic dermatitis in children under three years old.
• To synthesize findings from existing research on prebiotic and probiotic supplementation for infant atopic dermatitis.
• To identify specific strains or combinations with potential therapeutic benefits.

Main Methods:

• A narrative review of 13 key articles published since 1997.
• Analysis of studies involving supplementation with single or mixed probiotics, probiotics with formula, or prebiotics.
• Inclusion of studies with a total of 3,023 participants receiving supplements or placebo.

Main Results:

• 61.5% of studies (8/13) reported a significant preventive effect of prebiotics and/or probiotics on atopic dermatitis development.
• 38.5% of studies (5/13) indicated a significant reduction in atopic dermatitis severity.
• Lactobacillus rhamnosus GG and specific probiotic mixes showed effectiveness; prebiotics demonstrated long-term incidence reduction.

Conclusions:

• Supplementation with certain probiotics, notably Lactobacillus rhamnosus GG, and specific probiotic combinations appears effective for atopic dermatitis prevention and severity reduction in infants.
• Prebiotic supplementation may lead to a long-term decrease in atopic dermatitis incidence.
• Further interventional studies are necessary to establish definitive recommendations for prebiotic and probiotic use in infant atopic dermatitis.
