    OBJECTIVE: To review the effects of probiotics and prebiotics in clinical pediatric practice. SOURCES: MEDLINE was searched, especially for articles that addressed their practical application, in the form of reviews, clinical trials and meta-analyses. Articles that had already been analyzed by the authors were also included. SUMMARY OF THE FINDINGS: Scientific literature on probiotics and prebiotics has remarkably increased in the last 10 years. Their mechanisms of action have been experimentally investigated. Studies indicate that probiotics can act by competing with pathogens, modifying the intestinal environment by reduction in pH, as a result of fermentation products, interacting and modulating local and systemic inflammatory and immune response, among others. Clinical trials and meta-analyses show that probiotics seem to contribute towards the prevention of acute diarrhea and of antibiotic-associated diarrhea, in addition to shortening the duration of acute diarrhea. However, the data are inconsistent and there are no studies confirming their efficacy in terms of cost-benefit ratio. Preliminary studies show that probiotics in early life can reduce the occurrence of atopic dermatitis. The addition of prebiotics to infant formulas is associated with the change in the profile of the intestinal microbiota compared to infants fed milk formulas without prebiotics. CONCLUSIONS: Evidence indicates that new studies should be carried out about probiotics, prebiotics and symbiotics. The specific clinical effects that each probiotic or prebiotic may cause must be considered.

    Prebióticos, probióticos e simbióticos na prevenção e tratamento das doenças alérgicas
    (Sociedade de Pediatria de São Paulo, 2010-03-01) Souza, Fabíola Suano [UNIFESP]; Cocco, Renata Rodrigues [UNIFESP]; Sarni, Roseli Oselka Saccardo [UNIFESP]; Mallozi, Marcia Carvalho [UNIFESP]; Solé, Dirceu [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Fundação Faculdade de Medicina do ABC Disciplina de Pediatria
    OBJECTIVE: To review current evidence about the effects of probiotics, prebiotics and symbiotics on the immune development as well as on the prevention of allergic diseases in children. DATA SOURCES: Randomized, double-blind clinical trials in humans published in the last five years, in the Medline database, containing the following keywords: prebiotics (oligosaccharides), probiotics, symbiotics and hypersensitivity. DATA SYNTHESIS: For this review three papers with prebiotics were included, all of them using a mixture of GOS:FOS (9:1) in infant formula for the first months of life; 24 papers with probiotics, where L. rhamnosus GG, B. lactis, L. casei, L. paracasei, L. reuteri, L. acidophilus, B. longum, B. breve and P. freudenreichii sp. were the tested bacterial strains; and two papers about symbiotics. CONCLUSIONS: Although there are some evidence of benefits of early supplementation with some specific probiotic strains, prebiotics and symbiotics for the prevention of atopic eczema in children with high risk of allergy development, and probiotic use for the treatment of IgE-mediated moderate and severe atopic dermatitis, further research is needed in order to extended the evaluation of supplemented individuals, safety aspects and long term effects
