Probiotics for allergic respiratory diseases--putting it into perspective

Area of Science:

• Immunology
• Microbiology
• Allergology

Background:

• Respiratory allergies, including allergic rhinitis, sinusitis, and asthma, are increasing.
• The "atopic march" hypothesis suggests eczema precedes asthma and allergic rhinitis.
• The "hygiene hypothesis" links increased allergies to reduced childhood infections and microbial exposure.

Purpose of the Study:

• To discuss the current status of probiotics in the prevention and treatment of respiratory allergies.
• To explore the role of gut microbiota modulation by probiotics in allergic airway diseases.

Main Methods:

• Review of clinical trials and studies on probiotics and allergic diseases.
• Analysis of the impact of probiotics on the host immune system via the gut ecosystem.
• Examination of differences in intestinal microbiota in infants with allergic diseases.

Main Results:

• Probiotics, live beneficial organisms, show potential in preventing and treating allergic diseases.
• Probiotics modify the host immune system through the gut ecosystem.
• Feeding probiotics to at-risk infants has been shown to reduce eczema development.

Conclusions:

• Probiotics hold promise for managing respiratory allergies.
• Further research into probiotics for respiratory allergy prevention and treatment is warranted.
• Modulating the gut microbiota with probiotics is a potential strategy for allergic airway diseases.
