Abstract Allergic disorders are very common in the pediatric age group. While the exact etiology is unclear evidence is mounting to incriminate environmental factors and an aberrant gut microbiota with a shift of the Th1 Th2 balance towards a Th2 response. Probiotics have been shown to modulate the immune system back to a ThI response. Several in vitro studies suggest a role for probiotics in treating allergic disorders. Human trials demonstrate a limited benefit for the use of probiotics in atopic dermatitis in a preventive as well as a therapeutic capacity. Data supporting their use in allergic rhinitis are less robust. Currently there is no role for probiotic therapy in the treatment of bronchial asthma. Future studies will be critical in determining the exact role of probiotics in allergic disorders. Introduction Currently an estimated 20 of the population worldwide is suffering from some form of allergic disorder with a prevalence that continues to rise 1 . For example the prevalence of childhood asthma in the USA increased by 50 from 1980 to 2000 2 . Atopic diseases involve Th2 responses to allergens 3 . These clinical
