Even though probiotics have long been associated with prevention and improvement of symptoms in atopic disease like atopic dermatitis, a new study by scientists in the Division of Immunology and Allergy, Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland Nestle Research Centre, Lausanne, Switzerland, has looked at the effects of probiotics on upper airways allergies for the first time. In a double-blind, placebo-controlled, randomised study, either Lactobacillus paracasei ST11 or a placebo was administered to 31 people with allergic rhinitis, over two 4-week periods, with break in between of six weeks. The effects of the short-term oral administration were that those who had been receiving the probiotic (ST11 fermented milk) had lower nasal congestion than subjects receiving the placebo. There was no significant change between the two time periods, but the scientists concluded that short-term treatment suggests that probiotics may decrease symptoms of allergic rhinitis, and advise that further seasonal trials be undertaken.
