Effect of the Multi-Strain Probiotic SYN-53 in the Management of Allergic Rhinoconjunctivitis

Area of Science:

• Immunology
• Microbiology
• Allergology

Background:

• Gut dysbiosis is increasingly implicated in the development of allergic diseases.
• Allergic rhinoconjunctivitis (ARC) is a common allergic condition affecting many individuals globally.
• Probiotics are being explored for their potential to modulate immune responses and manage allergies.

Purpose of the Study:

• To evaluate the efficacy of the multi-strain probiotic SYN-53 in managing symptoms of allergic rhinoconjunctivitis (ARC).
• To assess the impact of SYN-53 on symptom severity and relief in individuals with grass pollen allergy.

Main Methods:

• Eighty-four subjects with confirmed grass pollen allergy participated in the study.
• Subjects underwent up to three bi-weekly 3-day intake cycles of SYN-53 or a placebo.
• ARC symptoms were assessed using the Total Symptom Score (TSS) after allergen exposure in a controlled chamber.

Main Results:

• SYN-53 demonstrated a trend towards greater efficacy than placebo after one cycle, becoming significant after two cycles (38% vs. 24% symptom relief).
• In subjects with moderate to severe symptoms, SYN-53 showed significant superiority after one cycle (45% vs. 26% symptom relief) and improved further with two cycles.
• The study highlights a significant reduction in ARC symptoms with SYN-53, particularly in more severe cases.

Conclusions:

• The multi-strain probiotic SYN-53 is effective in the management of allergic rhinoconjunctivitis.
• The findings underscore the role of bacterial diversity and appropriate dosage in probiotic supplements for allergy management.
• SYN-53 presents a promising therapeutic option for individuals suffering from ARC.
