The results of the present meta- analysis show that probiotic supplementation  prevents infantile eczema , thus suggesting a new potential indication for probiotic use in pregnancy and infancy
Growing evidence underlines the pivotal role of infant gut colonization in the development of the immune system .
The possibility to modify gut colonization through probiotic supplementation in childhood might prevent atopic diseases .
The aim of the present systematic review and meta- analysis was to evaluate the effect of probiotic supplementation during pregnancy and early infancy in preventing atopic diseases .
Probiotics in primary prevention of atopic disease: a randomised placebo-controlled trial
BACKGROUND Reversal of the progressive increase in frequency of atopic disease would be an important breakthrough for health care and wellbeing in western societies . In the hygiene hypothesis this increase is attributed to reduced microbial exposure in early life . Probiotics are cultures of potentially beneficial bacteria of the healthy gut microflora . We assessed the effect on atopic disease of Lactobacillus GG ( which is safe at an early age and effective in treatment of allergic inflammation and food allergy ) . METHODS In a double-blind , r and omised placebo-controlled trial we gave Lactobacillus GG prenatally to mothers who had at least one first-degree relative ( or partner ) with atopic eczema , allergic rhinitis , or asthma , and postnatally for 6 months to their infants .  Chronic recurring atopic eczema , which is the main sign of atopic disease in the first years of life , was the primary endpoint . FINDINGS  Atopic eczema was diagnosed in 46 of 132 ( 35 % ) children aged 2 years . Asthma  was diagnosed in six of these children and allergic rhinitis in one . The frequency of atopic eczema in the probiotic group was half that of the placebo group ( 15/64 [ 23 % ] vs 31/68 [ 46 % ] ; relative risk 0.51 [ 95 % CI 0.32 - 0.84 ] ) . The number needed to treat was 4.5 ( 95 % CI 2.6 - 15.6 ) . INTERPRETATIONS Lactobacillus GG was effective in prevention of  early atopic disease in children at high risk . Thus , gut microflora might be a hitherto unexplored source of natural immunomodulators and probiotics , for prevention of atopic disease
