Effects of a Probiotic Formulation on Seasonal Allergic Rhinitis in Adults-A Randomized Double-Blind Placebo-Controlled Trial: The Probiotics for Hay Fever Trial.

ABSTRACT:

Background

Seasonal-allergic-rhinitis (hay fever) affects approximately 4.6 million (20%) Australians each year. Hay fever manifests as runny/blocked nose and often itchy/sore/swollen eyes, with symptoms greatly impacting the quality of life. Rescue medications such as antihistamines are often needed to restore function, but they may trigger some other unwanted side effects. Probiotics have shown promise to reduce hay fever symptoms.

Objective

In this randomized double-blind placebo-controlled 12-week trial, we aimed to assess the tolerability and efficacy of the probiotic formula "NC-Seasonal-Biotic" on symptoms, quality-of-life, and immunological and microbial factors.

Methods

Adults, who had previously suffered from hay fever symptoms, were screened for eligibility
