Segundo a OMS, probióticos são “microrganismos vivos que administrados em quantidades adequadas conferem benefícios à saúde do hospedeiro”. No presente artigo de revisão, buscou-se descrever a atividade imunomoduladora e antimicrobiana de probióticos. O trabalho mostrou que, fundamentalmente, a atividade imunomoduladora de probióticos está relacionada ao estímulo de expressão de citocinas anti-inflamatórias, tais como IL-10 e TGF- β, bem como a produção de IgA e a ativação de células T reguladoras. Em relação a atividade antimicrobiana, os efeitos benéficos sobre a homeostasia da microbiota normal são os mais descritos, além da produção de enzimas bacteriolíticas, subprodutos de via metabólica (ácidos orgânicos e peróxido de hidrogênio) e bacteriocinas, todos com ação antimicrobiana. Conclui-se que os probióticos são ferramentas úteis de promoção de saúde, especialmente aquela relacionada ao trato digestório.

Background Evidence indicates that inflammation in Inflammatory Bowel Disease (IBD) is associated with increased systemic levels of reactive oxygen species. Systemic oxidative stress has been associated with reduced levels of plasma thiols. Less invasive tests capable of reflecting and predicting IBD activity are increasingly sought after. In this sense, we sought to systematically review the evidence inherent in serum thiol levels as a marker of Crohn's Disease and Ulcerative Colitis activity (PROSPERO: CRD42021255521). Methods The highest quality documents for systematic reviews and meta-analyses standards were used as reference. The highest quality documents for systematic reviews and meta-analyses standards were used as reference. Articles were searched on Medline via PubMed and via Central, VHL, LILACS, WOS, EMBASE, SCOPUS, COCHRANE, CINAHL, OVID, CTGOV, WHO/ICTRP, OPENGREY, BDTD and CAPES, between August and September/2021. Descriptors were defined according to the Medical Subject Heading.The articles were searched between August and September/2021. Of the 11 articles selected for full reading, 7 were included in the review. Of these, 4 were combinable studies and were included in the meta-analysis. Results The findings of the individual studies included suggest an association between disease activity and systemic oxidation, as measured by serum thiol levels, however, the pooled analysis did not identify a significant association between the parameters evaluated. The limitations identified in this meta-analysis made it impossible to weigh the results of individual studies, which, associated with potential confounding factors, may have interfered with the results of the grouped assessment. Conclusions We recommend conducting randomized clinical trials, with individuals of both phenotypes and in different stages of IBD, involving larger numbers of participants, using standardization of the technique for measuring serum thiols, in order to confirm whether thiols can be a good parameter of monitoring the clinical course of these intestinal diseases and the degree of clinical applicability.

Articles were searched on Medline via PubMed, VHL, LILACS, WOS, EMBASE, SCOPUS, COCHRANE, CINAHL, OVID, CTGOV, WHO/ICTRP, OPENGREY, BDTD and CAPES, between August, 03 and September, 03 on 2021. Descriptors were defined according to the Medical Subject Heading. Of the 11 articles selected for full reading, 8 were included in the review. It was not possible to perform a pooled analysis of the studies, as there were no combinable studies between subjects with active IBD and controls/inactive disease. Results Findings from the individual studies included in this review suggest an association between disease activity and systemic oxidation, as measured by serum thiol levels, however, there are limitations that preclude weighting the study results in a meta-analysis. Conclusions We recommend conducting better-designed and controlled studies, that include individuals of both phenotypes and at different stages of IBD, involving a larger number of participants, using the standardization of the technique for measuring serum thiols, to confirm whether thiols can be a good parameter for monitoring the clinical course of these intestinal diseases and the degree of clinical applicability.

Objective:The study's purpose has been to further understand the repercussions that Celiac Disease has on the adults' life quality. Methods: It is an integrative literature review, which has used the following databases for the selection of articles published between 2006 and 2017: LILACS, VHL, SciELO, MEDLINE, CINHAL and CAPES periodic portal. Results: Twenty articles were fully scrutinized. Based on the content analysis stages, the following three categories appeared: Eating practices of adults bearing the Celiac Disease; Quality of life of the Celiac Disease bearing adult; Importance of the patient care team in the diagnosis and follow-up of adults bearing the Celiac Disease. Conclusion: It is expected that science finds other means of treatment, in addition to the restrictive diet and/or the fact that the industry may adapt to the needs of adult subjects, by offering quality products and low cost, for inclusive and sociable access, then reducing the suffering generated by the disease. RESUMOObjetivo: Compreender as repercussões que a Doença Celíaca acarreta na qualidade de vida do sujeito adulto, por meio de uma revisão integrativa. Método: Revisão integrativa, com buscas nas bases de dados LILACS, BVS, SciELO, MEDLINE, CINHAL e portal de periódicos CAPES, com seleção de artigos publicados entre 2006 e 2017.Resultados: Foram analisados 20 artigos ao final na íntegra. Pautada nas etapas de análise de conteúdo, três categorias emergiram: Práticas alimentares do adulto com Doença Celíaca; Qualidade de vida do adulto com Doença Celíaca; Importância da equipe multiprofissional de saúde no diagnóstico e acompanhamento do adulto com Doença Celíaca. Conclusão: A perspectiva de que a ciência encontre outros meios de tratamento, além da dieta restritiva e/ou a indústria se adeque às necessidades dos sujeitos adultos, por meio da oferta de produtos de qualidade e baixo custo, para o acesso inclusivo e sociável, diminuindo o sofrimento gerado pela doença. Descritores: Doença Celíaca, Glúten, Adulto, Qualidade de Vida, Equipe Multiprofissional.RESUMEN Objetivo: Comprender las repercusiones que la Enfermedad Celíaca acarrea en la calidad de vida del sujeto adulto, por medio de una revisión integrativa. Método: La revisión integrativa, con búsquedas en las bases de datos LILACS, BVS, SciELO, MEDLINE, CINHAL y portal de revistas CAPES, con selección de artículos publicados entre 2006 y 2017. Resultados: Se analizaron 20 artículos al final en su totalidad. En las etapas de análisis de contenido, trescategorías emergieron: Prácticas alimentarias del adulto con enfermedad celíaca; Calidad de vida del adulto con enfermedad celiaca; Importancia del equipo multiprofesional de salud en el diagnóstico y acompañamiento del adulto con enfermedad celíaca.
