RESUMO

The objective of the present study was to explore the influence of dietary supplementation with a mixed additive (MA) containing a probiotic and anti-mycotoxin (Saccharomyces cerevisiae RC016 and Lactobacillus rhamnosus RC007) and its interaction on the performance and health (biochemistry and liver/intestine histopathology) of broilers fed diets contaminated with aflatoxin B1 (AFB1) at 506000±22.1ng/kg. The MA contained S. cerevisiae RC016 (1×107cells/g) and L. rhamnosus RC007 (1×108cells/g) in relation 1:1. A total of sixty-one-day-old Cobb broilers were randomly allocated into four treatment groups with three replicates of 5 birds each for a five-week-old feeding experiment. The experimental diet for each treatment (T) was formulated as follows: T1, a commercial diet (CD); T2, CD+AFB1; T3, CD+0.1% MA; T4, CD+AFB1+0.1% MA. The MA improved (p<0.01) production parameters (weight gain, conversion rate, and carcass yield) and reduced (p<0.01) the toxic effect of AFB1 on the relative weight of the livers. In addition, the macro and microscopic alterations of livers and the possible intestinal injury related to histological damage in the presence of mycotoxin were reduced. The use of probiotic MA based on S. cerevisiae RC016 and L. rhamnosus RC007 in animal feed provides greater protection against mycotoxin contamination and is safe for use as a supplement in animal feed, providing beneficial effects that improve animal health and productivity. This is of great importance at the economic level for the avian production system.

RESUMO

Due to extensive application of antibiotics as growth promoters in animal feed, antimicrobial resistance has been increased. To overcome this challenge, rumen microbiologists search for new probiotics to improve the rate of livestock production. The present study was aimed to isolate and evaluate breed-specific lactic acid bacteria (LAB) as potential animal probiotics. The current study was conducted during 10 months from July 2020 to April 2021, in which a total of n=12 strains were isolated from different samples including milk, rumen, and feces of Nilli Ravi Buffaloes. These isolates were evaluated for their antimicrobial potential against common animal pathogens (Bacillus spp., E. coli, Staphylococcus aureus, Salmonella spp., Listeria spp.). All the isolates were identified using 16S rRNA gene sequencing and the phylogenetic analyses inferred that these strains showed close relations to the species of various genera; Enterococcus lactis, Pediococcus pentosaceus, Bacillus subtilis Weissella cibaria, Weissella soli, Bacillus tequilensis, Weissella bombi, Bacillus licheniformis, Lactococcus lactis, Bacillus megaterium, Lactobacillus ruminis, and Lactococcus lactis. NMCC-Ru2 has exhibited the enormous potential of antimicrobial activity, 28 mm, for Salmonella typhimurium;23 mm for Listeria monocytogenes 21 mm for E.coil. Highest resistance was seen in NMCC-Ru2 agasint test antbiotic, like 25.5 mm for Tetracycline. Overall results revesl that the probiotic profile of isolates was achieved using standard criteria, particularly with animal probiotic properties

RESUMO

ABSTRACT Objective: To perform a systematic review of randomized controlled trials, evaluating the effect of probiotics, prebiotics or symbiotics supplementation on glycemic and inflammatory control in children with Type 1 Diabetes Mellitus (T1DM). Data source: The Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Clinical Trials, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Electronic Library Online (SciELO) databases were searched. Randomized clinical trials of pediatric patients with DM1 using probiotics, prebiotics or symbiotics were included, regardless of year or language of publication. Studies that did not evaluate glycated hemoglobin (HbA1c) were excluded. Metabolic results (HbA1c, total insulin dose and C-peptide) and inflammatory control [interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ)] during probiotic supplementation or similar, related to modification of the intestinal microbiota, were analyzed. PROSPERO ID: CRD42022384485. Data synthesis: Five studies were selected for a systematic review. Regarding metabolic markers, only one of the articles that analyzed HbA1c showed a significant decrease (p=0.03) in the intervention group. One study identified a reduction in the total dose of insulin and increased C-peptide levels. Regarding the evaluation of inflammatory parameters (IL-10, TNF-α, INF-γ), there were no statistical relevant modifications. Conclusions: Current data from the literature were not conclusive in identifying an improvement in glycemic control and did not observe changes in inflammatory parameters with the use of probiotics, prebiotics or symbiotics in pediatric patients with T1DM.

RESUMO Objetivo: Realizar uma revisão sistemática de ensaios clínicos randomizados controlados avaliando o efeito da suplementação de probióticos, prebióticos ou simbióticos no controle glicêmico e inflamatório em crianças com diabetes mellitus tipo 1 (DM1). Fontes de dados: As bases Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Clinical Trials, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Scientific Electronic Library Online (SciELO) foram pesquisadas. Foram incluídos ensaios clínicos randomizados de pacientes pediátricos com DM1 em uso de probióticos, prebióticos ou simbióticos, independentemente de ano ou idioma de publicação. Foram excluídos os trabalhos que não avaliaram hemoglobina glicada (HbA1c). Os resultados metabólicos (HbA1c, dose de insulina total e peptídeo C) e o controle inflamatório [interleucina-10 — IL-10), fator de necrose tumoral-alfa (TNF-α) e interferon-gama (IFN-γ)] durante a suplementação de probióticos ou similares, relacionados à modificação da microbiota intestinal, foram analisados. ID PROSPERO: CRD42022384485. Síntese dos dados: Cinco estudos foram selecionados para revisão sistemática. Com relação aos marcadores metabólicos, apenas um dos artigos que analisaram a HbA1c apresentou diminuição significativa (p=0,03) no grupo intervenção. Um estudo identificou redução da dose total de insulina e aumento dos níveis de peptídeo C. Quanto à avaliação dos parâmetros inflamatórios (IL-10, TNF-α, INF-γ), não houve modificações de relevância estatística. Conclusões: Os dados atuais da literatura não foram conclusivos em identificar melhora no controle glicêmico e não observaram mudanças nos parâmetros inflamatórios com o uso de probióticos, prebióticos ou simbióticos em pacientes pediátricos com DM1.

RESUMO

This study aimed to assess the impact of two commercial Saccharomyces cerevisiae strains (CHY1 and CHY2) on the intestinal health and performance of weaned piglets challenged with enterotoxigenic Escherichia coli during the nursery phase. One hundred ninety-two piglets with an average weight of 6.70 ± 0.92 kilograms were allocated in a randomized block design to one of four treatments: a negative control (C) without E. coli challenge and no yeast supplementation; a positive control (CH) with E. coli challenge and no yeast supplementation; and two treatment groups receiving an E. colichallenge with a CHY1 and CHY2 yeast strain supplementation. The challenge involved inoculating piglets with two dosages of E. coli F4 (106 CFU/ml and 109 CFU/ml) and a saline solution for the C group. Samples of intestinal tissue, blood, and cecal content were collected on the trial's 11th, 28th, and 42nd days. All variables were subjected to analysis of variance, and upon detecting significant differences via the F-test (p < 0.05), Tukey's test was applied to compare treatment means. For the analysis of diarrhea occurrence, the Kruskal-Wallis test was applied. When variables were rejected at a 5% probability level, a Dunn's test was conducted as a post-hoc analysis for paired multiple comparisons (p < 0.05), with statistical significance set at this level. Weaned piglets supplemented with CHY1 exhibited superior performance metrics, including higher average daily gain (15.3% increase), body weight (3.4% increase), feed-to-gain ratio (9.5% increase), and average daily feed intake (12.3% increase) at 28 days compared to the CH group across two different nutritional phases. No discernible effects were observed on measuring blood parameters, intestinal morphology, or cecal short-chain fatty acids. Both yeast-treated groups displayed improved performance during the most challenging periods. However, the CHY1 yeast strain contributed to enhanced piglet performance in the initial 28 days without inducing changes in intestinal morphology.(AU)

O presente estudo teve como objetivo avaliar duas cepas comerciais de Saccharomyces cerevisiae (designadas como CHY1 e CHY2) sob a saúde intestinal e desempenho de leitões desmamados desafiados com Escherichia coli enterotoxigênica durante a fase de creche. Um total de 192 leitões com peso médio 6,70 ± 0.92 quilogramas foram distribuídos em um delineamento em blocos casualizados com quatro tratamentos: um controle negativo (C) sem desafio de E. coli e sem suplementação da levedura; um controle positivo (CH) com desafio de E. coli e sem a suplementação da levedura; e dois grupos com a suplementação das dietas com as cepas comerciais das leveduras intituladas CHY1 e CHY2, juntamente ao desafio de E. coli. O desafio envolveu a inoculação de duas doses de E. coli F4 (106 UFC/ml e 109 UFC/ml) nos leitões e uma inoculação de solução salina para o grupo C. Amostras de tecido intestinal, sangue e conteúdo cecal foram coletadas nos 11º, 28º e 42º dias do experimento. Todas as variáveis foram submetidas a análise de variância e quando detectada diferença significativa pelo teste de F (p<0,05), o teste de Tukey foi aplicado para comparar as médias. Para a avalição da ocorrência de diarreia, o teste de Kruskal-Wallis foi aplicado e quando as variáveis foram rejeitadas ao nível de 5% de probabilidade, o teste de Dunn foi conduzido como uma análise post-hoc para comparações múltiplas (p<0,05) com significância estatística nesse nível. Leitões desmamados suplementados com CHY1 apresentaram métricas de desempenho superiores, incluindo maior ganho de peso diário (aumento de 15.3%), peso vivo (aumento de 3.4%), consumo de ração diário (aumento de 9.5%) e melhor eficiência alimentar (aumento de 12.3%) até os 28 dias de experimento em comparação com o grupo CH. Não foram observados efeitos dos tratamentos sobre os parâmetros sanguíneos mensurados, morfologia intestinal ou ácidos graxos de cadeia curta presentes no conteúdo cecal. Ambos os grupos tratados com leveduras apresentaram melhor desempenho durante os períodos mais desafiadores. No entanto, a cepa de levedura CHY1, especificamente, contribuiu para um melhor desempenho dos leitões nos primeiros 28 dias, sem induzir alterações na morfologia intestinal.(AU)

RESUMO

A periodontite é definida como uma doença inflamatória crônica de natureza multifatorial associada com biofilme disbiótico. O tratamento padrão para periodontite é a Raspagem e Alisamento Radicular (RAR), no entanto quando há a presença de bolsas profundas, áreas com dificuldades de inacessibilidade como lesão de furca ou perfil microbiológico especifico, pode ser necessário a prescrição de métodos auxiliares como a antibioticoterapia. No entanto o uso de antibióticos pode causar efeitos indesejáveis. Diante disso, ao longo dos últimos anos vem crescendo o interesse de estudos sobre o uso de probióticos no tratamento da periodontite, uma vez que estes são microrganismos vivos, ou seja, que quando ingeridas corretamente são benéficas à saúde. Diante disso o presente trabalho teve como objetivo realizar uma revisão de literatura quanto ao uso de probióticos como adjuvante no tratamento da periodontite, onde foram avaliados diversos artigos científicos. Foi observado que o uso de probióticos como adjuvantes no tratamento periodontal é benéfico, no entanto, há a necessidade de realização de mais estudos para averiguação da eficiência do mesmo, assim como a necessidade deste uso ser mais conhecido pelos Cirurgiões dentistas(AU)

Periodontitis can be defined as a chronic inflammatory disease of a multifactorial nature associated with a dysbiotic biofilm. The standard treatment for periodontitis is Scaling and Root Planing (RAR, in Portuguese), however when there is the presence of deep pockets, areas with inaccessibility difficulties such as furcation lesion or specific microbiological profile, it can be necessary to prescribe auxiliary methods such as antibiotic therapy. However, the use of antibiotics can cause undesirable effects. In view of this, over the last few years, interest in studies on the use of probiotics in the treatment of periodontitis has been growing, since these are live microorganisms, that is, when ingested correctly they are beneficial to health. Therefore, the present article aimed to carry out a literature review regarding the use of probiotics as an adjuvant in the treatment of periodontitis, where several scientific articles were analyzed. It was observed that the use of probiotics as adjuvants in periodontal treatment is beneficial, however, there is a need to carry out more studies to investigate if it's really efficient, as well the dentists needs to be known about the right use(AU)

RESUMO

El consumo de probióticos, prebióticos y posbióticos, o su combinación, puede contribuir a mantener una microbiota intestinal saludable ya que permite la regulación de su disbiosis en el caso de algunas enfermedades o trastornos, principalmente en los trastornos gastrointestinales funcionales (TGIF). El microbioma intestinal es protagonista esencial en la fisiopatología de los TGIF a través de sus funciones metabólicas y nutricionales, el mantenimiento de la integridad de la mucosa intestinal y la regulación de la respuesta inmunitaria. Las investigaciones realizadas hasta la fecha indican que los probióticos, prebióticos y posbióticos pueden tener efectos inmunomoduladores directos y clínicamente relevantes. Existen pruebas del uso de esta familia de bióticos en individuos sanos para mejorar la salud general y aliviar los síntomas en una serie de enfermedades como los cólicos infantiles. La colonización y establecimiento de la microbiota comienza en el momento del nacimiento; los primeros 2-3 años de vida son fundamentales para el desarrollo de una comunidad microbiana abundante y diversa. Diversos estudios científicos realizados mediante técnicas tradicionales dependientes de cultivo y más recientemente por técnicas moleculares han observado diferencias en las poblaciones bacterianas de bebés sanos y aquellos que sufren TGIF, estos últimos caracterizados por un aumento de especies patógenas y una menor población de bifidobacterias y lactobacilos, en comparación con los primeros. En tal contexto, se considera que la microbiota intestinal como protagonista en el desarrollo de esos trastornos, entre ellos los cólicos infantiles, a través de sus funciones metabólicas, nutricionales, de mantenimiento de la integridad de la mucosa intestinal y regulación de la respuesta inmunitaria. Esto ha abierto la puerta al estudio de la utilización de prebióticos, probióticos y posbióticos en el tratamiento y/o prevención de los TGIF infantiles. El parto vaginal y de término así como la lactancia son fundamentales en la constitución de una microbiota saludable. Como herramientas de apoyo, existen estudios de eficacia que sustentan la administración de esta familia de bióticos, principalmente en los casos en que la lactancia no sea posible o esté limitada. (AU)

The consumption of probiotics, prebiotics, and postbiotics, or a combination of them, can contribute to maintaining a healthy intestinal microbiota as it allows the regulation of its dysbiosis in the case of some diseases or disorders, mainly in functional gastrointestinal disorders (FGIDs). The gut microbiome is an essential player in the pathophysiology of FGIDs through its metabolic and nutritional functions, the maintenance of intestinal mucosal integrity, and the regulation of the immune response. Research results thus far indicate that probiotics, prebiotics, and postbiotics may have direct and clinically relevant immunomodulatory effects. There is evidence regarding the prescription of this family of biotics in healthy individuals to improve overall health and alleviate symptoms in many conditions like infantile colic. The colonization and microbiota establishment begins at birth; the first 2-3 years of life are critical for developing an abundant and diverse microbial community. Several scientific studies performed by traditional culture-dependent techniques and more recently by molecular techniques have observed differences in the bacterial populations of healthy infants and those suffering from FGIDs, the latter characterized by an increase in pathogenic species and a lower population of bifidobacteria and lactobacilli, compared to the former. In this context, the intestinal microbiota plays a leading role in the onset of these disorders, including infantile colic, through its metabolic and nutritional functions, maintenance of the integrity of the intestinal mucosa, and regulation of the immune response. That has opened the door to the study of prebiotics, probiotics, and postbiotics usage in the treatment and or prevention of infantile FGIDs. Vaginal and term delivery and breastfeeding are fundamental in the constitution of a healthy microbiota. As supportive tools, there are efficacy studies that support the administration of this family of biotics, mainly in cases where lactation is not possible or is limited.

RESUMO

La enfermedad celíaca y la sensibilidad al gluten no celíaca han tenido un aumento en su incidencia, esto las ha convertido en tema de interés en la búsqueda de enfoques terapéuticos innovadores que ayuden a mejorar los síntomas intestinales y extraintestinales. Esta revisión pretende determinar los efectos del uso de probióticos y prebióticos en la enfermedad celíaca y sensibilidad al gluten no celíaca. Se realizó una búsqueda en bases de datos HINARI, PubMed y Scopus en idioma español e inglés, se incluyeron artículos originales y de revisión con un máximo de cinco años desde su publicación. El uso de probióticos y prebióticos para la enfermedad celíaca ha mostrado beneficios restaurando la composición del microbiota intestinal, en especial con el uso de Lactobacilli y Bifidobacterium spp.; en la sensibilidad al gluten no celíaca, el uso se ve limitado al no conocer con exactitud su fisiopatología; no obstante, se propone como mejor pauta terapéutica una dieta libre de gluten. El uso de probióticos y prebióticos podría aliviar los síntomas gastrointestinales y mejorar la disbiosis en pacientes con enfermedad celíaca y sensibilidad al gluten no celíaca. Sin embargo, se necesitan más estudios que evidencien los beneficios de su uso como alternativa terapéutica

Celiac disease and non-celiac gluten sensitivity are entities that have shown an increase in incidence, making them a topic of interest to provide innovative therapeutic approaches and improve intestinal and extraintestinal symptoms. This review intends to determine the effects of the use of probiotics and prebiotics in celiac disease and non-celiac gluten sensitivity. A narrative review was undertaken by searching for original and review articles no older than five years since publication through data bases consulted: HINARI, PubMed and Scopus in Spanish and English. The use of probiotics and prebiotics in celiac disease has shown benefits by restoring the composition of the intestinal microbiota, especially with the use of Lactobacilli and Bifidobacterium spp.; in non-celiac gluten sensitivity, its use is limited as its pathophysiology is not exactly known, therefore, a gluten-free diet is currently considered to be the best therapeutic guideline. The use of probiotics and prebiotics could alleviate gastrointestinal symptoms and improve dysbiosis in patients with celiac disease and non-celiac gluten sensitivity. However, more studies are needed to demonstrate the benefits of its use as a therapeutic alternative

RESUMO

ABSTRACT Introduction: Supplementation with probiotics for patients with chronic kidney disease (CKD) may be associated with decreased systemic inflammation. Objective: To assess the impact of oral supplementation with probiotics for patients with CKD on hemodialysis. Method: This double-blind randomized clinical trial included 70 patients on hemodialysis; 32 were given oral supplementation with probiotics and 38 were in the placebo group. Blood samples were collected at the start of the study and patients were given oral supplementation with probiotics or placebo for three months. The probiotic supplement comprised four strains of encapsulated Gram-positive bacteria: Lactobacillus Plantarum A87, Lactobacillus rhamnosus, Bifidobacterium bifidum A218 and Bifidobacterium longum A101. Patients were given one capsule per day for 3 months. Blood samples were taken throughout the study to check for inflammatory biomarkers. Non-traditional biomarkers Syndecan-1, IFN-y, NGAL, and cystatin C were measured using an ELISA kit, along with biochemical parameters CRP, calcium, phosphorus, potassium, PTH, GPT, hematocrit, hemoglobin, glucose, and urea. Results: Patients given supplementation with probiotics had significant decreases in serum levels of syndecan-1 (239 ± 113 to 184 ± 106 ng/mL, p = 0.005); blood glucose levels also decreased significantly (162 ± 112 to 146 ± 74 mg/dL, p = 0.02). Conclusion: Administration of probiotics to patients with advanced CKD was associated with decreases in syndecan-1 and blood glucose levels, indicating potential improvements in metabolism and decreased systemic inflammation.

Resumo Introdução: A suplementação com probióticos na doença renal crônica (DRC) pode estar associada à redução do processo inflamatório sistêmico. Objetivo: Avaliar a suplementação oral com probióticos em pacientes com DRC em hemodiálise. Método: Ensaio clínico, duplo cego, randomizado com 70 pacientes em hemodiálise, sendo 32 do grupo que recebeu o suplemento de probióticos e 38 do grupo placebo. Inicialmente ocorreu a coleta de sangue e suplementação oral com probióticos ou placebo durante três meses. O suplemento probiótico foi composto pela combinação de 4 cepas de bactérias Gram-positivas encapsuladas: Lactobacillus Plantarum A87, Lactobacillus rhamnosus, Bifidobacterium bifidum A218 e Bifidobacterium longum A101, sendo 1 cápsula do suplemento ao dia, durante 3 meses. Após esse período foram feitas novas coletas de sangue para dosagem dos biomarcadores inflamatórios. Foram analisados os biomarcadores não tradicionais: Syndecan-1, IFN-y, NGAL e cistatina C pelo método ELISA, e os seguintes parâmetros bioquímicos: PCR, cálcio, fósforo, potássio, PTH, TGP, hematócrito, hemoglobina, glicose e ureia. Resultados: Os pacientes que receberam suplemento tiveram diminuição significativa dos níveis séricos de syndecan-1 (de 239 ± 113 para 184 ± 106 ng/mL, p = 0,005). Outro parâmetro que diminuiu significativamente nos pacientes que receberam suplemento foi a glicemia (de 162 ± 112 para 146 ± 74 mg/dL, p = 0,02). Conclusão: O uso de probióticos na DRC avançada esteve associado à redução dos níveis de syndecan-1 e glicemia, sinalizando possível melhora no metabolismo e redução do processo inflamatório sistêmico.
