Probiotics and prebiotics: clinical effects in allergic disease

Area of Science:

• Allergy and immunology
• Microbiome research
• Pediatric health

Background:

• Allergic diseases are increasing globally, posing a significant public health challenge.
• Primary prevention strategies for allergic diseases remain largely elusive.
• The role of the gut microbiome in immune system development is an area of intense research.

Purpose of the Study:

• To summarize recent clinical studies on the use of probiotics and prebiotics for allergic disease.
• To evaluate the efficacy of these interventions in the prevention and treatment of allergic conditions.
• To identify promising avenues for future research in allergy prevention.

Main Methods:

• Review of recent publications focusing on clinical trials.
• Analysis of studies investigating probiotics and prebiotics in allergic disease prevention and treatment.
• Synthesis of findings from systematic reviews, including a Cochrane review on probiotics for eczema.

Main Results:

• Certain probiotics, particularly with prebiotics and used prenatally, show potential for atopic eczema prevention.
• Evidence for probiotic treatment of established allergic disease is less convincing; a Cochrane review found no overall effectiveness for eczema.
• Prebiotic-supplemented formulas may help prevent eczema in high-risk infants when breastfeeding is not feasible.

Conclusions:

• Probiotic interventions represent a promising strategy for the primary prevention of allergic diseases.
• Further definitive intervention studies are a research priority to confirm the preventive potential of probiotics.
• Targeted research into prebiotic applications may also yield effective strategies for allergy prevention.
