Fructooligosaccharide is used widely in many foods and pharmaceutical industries and produced by using different ways such as extracting it from plants or producing it by using plants and microorganisms' enzymes. In a previous study, we extracted Fructosyltransferase (Ftase) enzyme from pineapple residue and produced FOS. In this study, we measured the antagonistic activity of two synbiotics, the first synbiotic containing Lactobacillus acidophilus and the produced FOS, the second synbiotic containing Lactobacillus acidophilus and standard FOS, against pathogenic bacteria (P. aeruginosa, E. coli, S. aureus and B cereus). The results showed that the antagonistic activity of both synbiotic types was very close, as there were no significant differences between them except in the antagonistic activity against S. aureus, there was a significant difference between the synbiotic containing the standard FOS, which was the highest in its antagonistic activity compared to the synbiotic containing the produced FOS in this study. The activity of the fructooligosaccharide (FOS) extracted from pineapple residue was evident in enhancing the activity of the probiotic bacteria (L. acidophilus), which had a major role in the production of acids and compounds that inhibited the pathogenic bacteria. The diameters of inhibition areas in the current study ranged between 19.33-28 mm, and E. coli was more susceptible to inhibition, followed by S. aureus, P. aeruginosa, and B. cereus, respectively.

O fruto-oligossacarídeo (FOS) é amplamente utilizado em muitos alimentos e indústrias farmacêuticas, e é produzido por meio de diferentes maneiras, como extraí-lo de plantas ou produzi-lo usando enzimas de plantas e microrganismos. Em um estudo anterior, extraímos a enzima frutosiltransferase (Ftase) do resíduo de abacaxi e produzimos FOS. Neste estudo, medimos a atividade antagônica de dois simbióticos: o primeiro simbiótico contendo Lactobacillus acidophilus e o FOS produzido, e o segundo simbiótico contendo Lactobacillus acidophilus e o FOS padrão, contra bactérias patogênicas (P. aeruginosa, E. coli, S. aureus e B. cereus). Os resultados mostraram que a atividade antagônica de ambos os tipos simbióticos foi muito próxima, pois não houve diferenças significativas entre eles, exceto na atividade antagônica contra S. aureus, em que houve uma diferença significativa entre o simbiótico contendo o FOS padrão, que foi o mais alto em sua atividade antagônica, em comparação com o simbiótico contendo o FOS produzido neste estudo. A atividade do fruto-oligossacarídeo (FOS) extraído do resíduo de abacaxi ficou evidente no aumento da atividade da bactéria probiótica (L. acidophilus), que teve papel importante na produção de ácidos e compostos inibidores das bactérias patogênicas. Os diâmetros das áreas de inibição no estudo atual variaram entre 19,33 e 28 mm, e E. coli foi mais suscetível à inibição, seguida por S. aureus, P. aeruginosa e B. cereus, respectivamente.

ABSTRACT Over the last years, there is growing evidence that microorganisms are involved in the maintenance of our health and are related to various diseases, both intestinal and extraintestinal. Changes in the gut microbiota appears to be a key element in the pathogenesis of hepatic and gastrointestinal disorders, including non-alcoholic fatty liver disease, alcoholic liver disease, liver cirrhosis, inflammatory bowel disease, irritable bowel syndrome, and Clostridium difficile - associated diarrhea. In 2019, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Nucleus for the Study of Helicobacter Pylori and Microbiota (NBEHPM), and Brazilian Federation of Gastroenterology (FBG) sponsored a joint meeting on gut microbiota and the use of prebiotics, probiotics, and synbiotics in gastrointestinal and liver diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to provide practical information about this topic, addressing the latest discoveries and indicating areas for future studies.

RESUMO Nos últimos anos, um volume crescente de evidências indica que os microrganismos estão envolvidos na manutenção da saúde humana e também estão relacionados a várias doenças, tanto intestinais quanto extraintestinais. Alterações na microbiota intestinal parecem ser um elemento chave na patogênese de doenças hepáticas e gastrointestinais, incluindo doença hepática gordurosa não-alcoólica, doença hepática alcoólica, cirrose hepática, doenças inflamatórias intestinais, síndrome do intestino irritável e diarreia associada ao Clostridium difficile. Em 2019, a Sociedade Brasileira de Hepatologia (SBH) em colaboração com o Núcleo Brasileiro para Estudo do Helicobacter pylori e Microbiota (NBEHPM) e a Federação Brasileira de Gastroenterologia (FBG) realizaram um encontro exclusivamente voltado para a discussão sobre microbiota e uso de prebióticos, probióticos e simbióticos em doenças hepáticas e gastrointestinais. Este texto resume os principais pontos discutidos durante o evento, e tem a intenção de fornecer informações práticas sobre o assunto, abordando as descobertas mais recentes e indicando áreas para estudos futuros.

BACKGROUND: A key challenge for manufacturers of pro-health food containing active probiotic microorganisms is to develop a product with attractive sensory features along with maintenance of declared number of microorganisms during storage and transfer by alimentary tract. RESULTS: The highest concentration of polyphenols was observed in snacks without an additive of probiotics as well as those with an additive of L. rhamnosus and B. animalis bacteria and concentration of these compounds increased by 9.5% during six months of storage. None of the products distinguished itself in the sensorial assessment although each was assessed positively. The number of microorganisms was stable and comparatively high during six months of storage at a room temperature and in cooling conditions (108 cfu/g). In the digestion model, an influence of aggressive digestion conditions was examined in the alimentary tract on the number of microorganisms, which allowed to arrange strains from the most resistant (S. boulardii) to the most sensitive (B. breve). It must be noted that currently on the market there is no available snack containing probiotic yeast as well as there is no literature data on works on such formulation of food. CONCLUSIONS: In the newly developed snack made of chocolate, in which sugar has been replaced with maltitol, a raw material was added in the form of raspberry, prebiotic in the form of inulin and a strain of probiotic bacteria, including the unprecedented so far S. boulardii, which stands a high chance to occupy a good place on the market of functional food.

En los últimos años, las evidencias han demostrado la importancia de la microbiota intestinal en la salud del individuo. La dinámica de la colonización temprana y el establecimiento de una comunidad abundante y diversa de microorganismos saludables, a partir de un parto vaginal y lactancia materna, resultan fundamentales en la conformación de una matriz inmunológica saludable. Esta revisión tiene como objetivo describir las evidencias disponibles sobre el desarrollo de la microbiota en el primer año de vida y el actual potencial que ofrece el uso de prebióticos, probióticos, simbióticos y posbióticos durante esta etapa esencial de la vida

In recent years, the evidence has demonstrated the relevance of the gut microbiota in an individual's health. The dynamics of an early colonization and the establishment of a community of plenty, diverse, and healthy microorganisms from a vaginal delivery and breastfeeding are critical for the development of a healthy immune matrix. The objective of this review is to describe the available evidence on microbiota development in the first year of life and the current possibilities offered by prebiotics, probiotics, symbiotics, and postbiotics during such critical stage of life.

Evaluate the effect of a synbiotic on salivary viscosity and buffer capacity. Materials and Methods: A follow-up one-week study was performed on 24 healthy volunteers in San Luis Potosí, Mexico, during July 2017. Volunteers must have had active tooth decay at the moment of study. All 24 patients were given a Lactiv® probiotic package, advising not to modify usual oral hygiene practices, and were followed up during 6 days. Primary output variable was salivary viscosity while the secondary was salivary buffer capacity. Salivary viscosity was assessed by using an Ostwald Pipette and buffer capacity with bromocresol purple. Results: A total of 8 male patients (33.3%) and 16 females (66.6%) patients were included, with an average age of 10.92 years. All the volunteers completed the study. Comparisons between pre- and post-treatment showed a decrease in salivary viscosity, while buffer capacity was showed to increase. Conclusion: The use of a synbiotic during a short period of time lowered the viscosity of saliva and increased salivary buffer capacity.

ABSTRACT BACKGROUND: Aging is a complex process marked by alterations on gut functioning and physiology, accompanied by an increase on the inflammatory status, leading to a scenario called "inflammaging". OBJECTIVE: To evaluate the effects of a synbiotic substance on systemic inflammation, gut functioning of community-dwelling elders. METHODS: This is a secondary analysis from a randomized clinical trial, lasting 24 weeks, including 49 elders, distributed into two groups: SYN (n=25), which received a synbiotic substance (Frutooligossacaride 6g, Lactobacillus paracasei LPC-31 109 to 108 UFC, Lactobacillus rhamnosus HN001 109 to 108 UFC, Lactobacillus acidophilus NCFM 109 to 108 UFC e Bifidobacterium lactis HN019 109 to 108 UFC), or PLA (n=24), receiving placebo. The evaluations consisted of serum IL-10 e TNF-α (after overnight fasting), evaluation of chronic constipation (by Rome III Criteria) and faeces types (by Bristol Stool Form Scale). Data were compared before and after the supplementation time, and between groups. RESULTS: No significant differences were found between baseline and final values of serum inflammatory markers. Some subtle beneficial changes were observed in SYN, concerning both gut functioning and faeces types. CONCLUSION: From our data, synbiotic supplementation showed a subtle benefit in gut functioning in apparently healthy community-dwelling elders. Our findings can suggest that the benefits in healthy individuals were less expressive than the ones presented in studies with individuals previously diagnosed as dysbiosis. Future studies, comparing elders with and without gut dysbiosis can confirm our findings.

RESUMO CONTEXTO: O envelhecimento é um processo complexo marcado por alterações no funcionamento e fisiologia intestinais, acompanhado de alterações no estado inflamatório, o que leva ao quadro denominado inflammaging. OBJETIVO: Avaliar os efeitos de uma substância simbiótica sobre o funcionamento intestinal e a inflamação sistêmica de idosos inseridos na comunidade. MÉTODOS: Trata-se de uma análise secundária de um estudo clínico randomizado, com 24 meses de duração, que incluiu 49 idosos, distribuídos em dois grupos: SIM (n=25), que receberam uma substância simbiótica (Frutooligossacaride 6g, Lactobacillus paracasei LPC-31 109 to 108 UFC, Lactobacillus rhamnosus HN001 109 to 108 UFC, Lactobacillus acidophilus NCFM 109 to 108 UFC e Bifidobacterium lactis HN019 109 to 108 UFC), ou PLA (n=24), que receberam placebo. As avaliações foram realizadas antes e após o período de suplementação, e incluíram: concentrações de IL-10 e TNF-α no soro (após uma noite de jejum); investigação de constipação crônica (pelo Critério de Roma III) e dos tipos de fezes (pela Escala de Bristol). Os dados foram comparados entre antes e após a suplementação, e entre os grupos. RESULTADOS: Não foram encontradas diferenças significativas entre valores iniciais e finais nos marcadores de inflamação; alguns benefícios sutis foram observados no grupo SIM, no funcionamento intestinal e nos tipos de fezes. CONCLUSÃO: A suplementação com simbióticos mostrou um benefício sutil nessa população. Nossos resultados apontam que idosos aparentemente saudáveis não se beneficiam tanto da suplementação de simbióticos quanto pessoas previamente identificadas com disbiose. Estudos futuros, comparando idosos com e sem disbiose poderão confirmar esses achados.

Introducción. Los probióticos y prebióticos presentan beneficios potenciales en la inflamacióncrónica de las mucosas, incluida la prevención de la enterocolitis necrosante. No obstante, los mecanismos y resultados de estos efectos inmunomoduladores son confusos. El objetivo fue investigar la respuesta de las citocinas a Lactobacillus y Bifidobacterium asociados con fructo- y galactooligosacáridos (simbióticos) y lactoferrina en recién nacidos de muy bajo peso al nacer.Población y métodos. Se asignó aleatoriamente a lactantes con ≤32 semanas de gestación y ≤1500 g de peso para recibir simbióticos o 1 ml de agua destilada como placebo desde la primera alimentación hasta el alta. Se obtuvieron muestras de sangre los días posnatales 0 ± 2, 14 ± 2 y 28 ± 2, y se midieron interferón-γ, interleucina (IL)-5, IL-10 e IL-17A.Resultados. En el grupo del estudio (n = 25), la concentración de IL-10 disminuyó a lo largo del estudio (p = 0,011), pero no cambió en el grupo de referencia. La concentración de IL-5 se mantuvo constante los primeros 14 días y luego disminuyó significativamente (p= 0,042) en el grupo del estudio, mientras que aumentó en los primeros 14 días (p = 0,019) y luego disminuyó en 28 días (p = 0,011) en el grupo de referencia (n = 25).La concentración de otras citocinas no cambió a lo largo del estudio.Conclusión. El uso combinado de probióticos con oligosacáridos y lactoferrina estuvo asociado con una disminución en la concentración de IL-10, pero no se observó un cambio en las otras citocinas.

Introduction. Probiotics and prebiotics, which are multifunctional agents, have potential benefits in chronic mucosal inflammation, including the prevention of necrotizing enterocolitis. However, the mechanisms and the results of these immunomodulatory effects are not clear. This study aimed to investigate the cytokine response to the combination of Lactobacillus and Bifidobacterium together with fructo- and galacto-oligosaccharides (symbiotic) and lactoferrin in very low birth weight neonates.Population and Methods. Infants ≤ 32 GWs and ≤ 1,500 g were randomly assigned to receive a symbiotic combination or 1 ml distilled water as placebo starting with the first feed until discharge. Blood samples were obtained at postnatal 0 ± 2, 14 ± 2, and 28 ± 2 days, and the serum levels of interferon-γ, interleukin (IL)-5, IL-10, and IL-17A were measured.Results. In the study group (n = 25), the IL-10 levels decreased throughout the study period (p = 0.011) but did not change in the control group. The IL-5 levels remained steady in the first 14 days and decreased significantly thereafter (p = 0.042) in the study group, whereas they increased in the first 14 days (p = 0.019), and then decreased in 28 days (p = 0.011) in the control group (n = 25). The levels of the other cytokines did not change throughout the study period.Conclusion.The combined use of probiotics with oligosaccharides and lactoferrin was associated with a decrease in IL-10 levels, but no change was observed in the other cytokines.

OBJETIVO: Comparar resultados da suplementação com prebiótico, probiótico e simbiótico para o controle da diarreia em pacientes idosos recebendo terapia nutricional enteral durante o internamento em um hospital escola de Curitiba, Paraná. MÉTODOS: O estudo foi retrospectivo, por análise de prontuários correspondentes aos atendimentos realizados entre 2014 e 2018. RESULTADOS: Obteve-se um total de 75 pacientes. O tempo de ocorrência de diarreia variou de 1 a 16 dias, sendo a média de 2,69 dias após a instituição de terapêutica para restabelecimento da microbiota intestinal. Quanto às terapias instituídas, foram encontradas oito possíveis prescrições de suplementos isolados e/ou combinados, como primeira escolha. Dos pacientes analisados, 52% trocaram de suplementação ao longo da ocorrência da diarreia; alguns chegando a utilizar até cinco diferentes produtos. Dos 48% de pacientes que utilizaram um único produto/combinação do início ao fim da diarreia, de modo geral iniciaram com uma dose maior e foram diminuindo ao longo do tempo, sendo que os que começaram com uma dose menor tiveram que aumentá-la para interromper a diarreia. Além disso, houve significância estatística quando comparado o tempo de diarreia entre pacientes que receberam um único produto/combinação e os que fizeram trocas de suplemento ao longo do tratamento. CONCLUSÃO: Estabelecer uma prescrição única, seja de produtos isolados ou combinados, e permanecer com ela, além de iniciar com uma dose maior, parece mais efetivo no controle da diarreia em idosos hospitalizados, reforçando a importância de se estabelecer um protocolo para prescrição.

OBJECTIVE: To compare results of prebiotic, probiotic and synbiotic supplementation for the control of diarrhea in older patients receiving enteral nutritional therapy during hospitalization at a school hospital in Curitiba, state of Paraná. METHODS: The study was retrospective, by analysis of medical records corresponding to the visits performed between 2014 and 2018. RESULTS: A total of 75 patients were analyzed. The time of occurrence of diarrhea ranged from 1 to 16 days, with a mean of 2.69 days after the onset of therapy for reestablishment of the intestinal microbiota. As for the therapies introduced, 8 possible prescriptions of isolated and / or combined supplements were found as the first choice. Of the patients analyzed, 52% switched from supplementation during the occurrence of diarrhea; some using up to 5 different products. Of the 48% of patients who used a single product / combination from the beginning to the end of diarrhea, they generally started with a higher dose and decreased over time, with those starting at a lower dose having to increase it to stop diarrhea. In addition, there was statistical significance when comparing the time of diarrhea between patients who received a single product / combination and those who did supplemental exchanges throughout the treatment. CONCLUSION: Establishing a single prescription, whether of isolated or combined products and sticking to it, besides starting with a higher dose, seems more effective in controlling diarrhea in hospitalized geriatric patients, reinforcing the importance of establishing a protocol for prescription.

BACKGROUND: This double-blind, randomized controlled design study aimed to assess the dose-dependent effects of synbiotics on gastrointestinal symptoms of and fatigue in irritable bowel syndrome (IBS). METHODS: Thirty subjects with IBS were randomly assigned into the following three groups and received 2 capsules a day for 8 weeks: (1) high-dose (2 capsules of synbiotics); (2) low-dose (1 capsule of synbiotics and 1 capsule of placebo); and (3) placebo (2 capsules of placebo). At baseline and 8 weeks, they completed the study questionnaires. RESULTS: Two subjects in the high-dose group were lost to follow-up, leaving a total of 28 patients for the analysis. After 8 weeks, abdominal discomfort, abdominal bloating, frequency of formed stool, fatigue Visual Analog Scale (VAS), and Multidimensional Fatigue Inventory were significantly different among the groups (P=0.002, 0.006, 0.007, 0.028, and 0.041, respectively, by Kruskal-Wallis test). However, only abdominal discomfort, abdominal bloating, frequency of formed stool, and fatigue VAS were significantly improved in the high-dose group compared with those in the placebo group (P=0.002, 0.003, 0.002, and 0.013, respectively) by Mann-Whitney test with Bonferroni correction. No adverse drug reactions were reported. CONCLUSION: High-dose synbiotics were superior to placebo in improving bowel symptoms and fatigue of IBS patients, suggesting that synbiotic dosage plays an important role in the treatment of IBS.

PURPOSE: Jaundice accounts for most hospital admissions in the neonatal period. Nowadays, in addition to phototherapy, other auxiliary methods are used to reduce jaundice and the length of hospitalization. This study aimed to investigate the effect of probiotics on the treatment of hyper-bilirubinemia in full-term neonates. METHODS: In this randomized clinical trial, 83 full-term neonates, who were admitted to the hospital to receive phototherapy in the first 6 months of 2015, were randomly divided into two groups: synbiotic (SG, n=40) and control (CG, n=43). Both groups received phototherapy but the SG also received 5 drops/day of synbiotics. Serum bilirubin, urine, stool, feeding frequency, and weight were measured daily until hospital discharge. A p-value<0.05 was considered statistically significant. RESULTS: The mean total serum bilirubin in the SG was lower than that in the CG (9.38±2.37 and 11.17±2.60 mg/dL, respectively). The urine and stool frequency in the SG was significantly higher than that in the CG (p<0.05). The duration of hospitalization in the SG was shorter than that in the CG. CONCLUSION: Use of synbiotics as an adjuvant therapy had a significant treatment effect on jaundice in full-term neonates. Further studies including larger samples with long follow-up periods are essential to confirm the benefits of routine use of synbiotics in neonatal patients with jaundice.

Quark cheese is fresh cheese obtained by the coagulation of milk through the action mainly of lactic bacteria, resulting in fresh-flavor cheese with high acidity. A specific starter culture is used for its commercial production. However, in this work, this culture was replaced by kefir, a symbiotic system of lactic acid bacteria and yeasts, which is considered a probiotic product. Agave inulin is a soluble fiber regarded as prebiotic with the ability to improve the balance of the intestinal flora. The purpose of this work was to develop Quark cheese using kefir as a starter culture, with supplementation by agave inulin. Cheese was produced using 24-h fermentation at 25 ºC followed by drainage of the whey, with the addition of 3% inulin to the supplemented cheese. After whey drainage, the cheese was kept in plastic pots under refrigeration until analysis. Microbiological, pH and acidity parameters were analysed at 1, 7 and 14 days after manufacture. The results of the physical-chemical analyses remained close to those found in literature. The resulting cheese presented high counts of Lactobacilli indicating their probiotic potential. The addition of agave inulin decreased the amount of those microorganisms; however, they remained in high counts. It can be verified that the use of kefir in the production of Quark cheese is feasible, mainly in artisanal productions since it is usually inexpensive and easy to maintain, and the Lactobacilli remained stable during the storage period.(AU)

O queijo Quark é um queijo de massa fresca obtida por coagulação do leite pela ação principalmente de bactérias láticasobtendo-se um queijo de sabor refrescante, em sua produção comercial é empregada uma cultura starter específica para a produção de queijos, no presente trabalho essa cultura foi substituída pelo kefir, um sistema simbiótico de bactérias láticas e leveduras e que é considerado um produto probiótico. A inulina de agave é uma fibra solúvel considerada prebiótica com capacidade de melhorar o equilíbrio da flora intestinal. O objetivo desse trabalho foi desenvolver queijo Quark empregando kefir como cultura starter e suplementado com inulina de agave. Os queijos foram produzidos por fermentação durante 24h/25ºC seguido por drenagem do soro, no queijo suplementado com inulina foi adicionada 3%, após a dessoragem, os queijos foram mantidos em potes plásticos sob temperatura de refrigeração até o momento das análises, sendo que as microbiológicas, acidez e pH foram realizadas em 1, 7 e 14 dias após a fabricação. Os resultados das análises físico-químicas mantiveram-se próximos aqueles encontrados na literatura. Os queijos obtidos apresentaram altas contagens de Lactobacilli indicando potencial probiótico, a adição de inulina de agave diminuiu o número destes microrganismos, mesmo assim mantiveram-se em altas contagens. Pode-se constatar que o uso de kefir na produção de queijo Quark é viável, principalmente em produções artesanais uma vez que ele normalmente não possui custo e é de fácil manutenção e os Lactobacillimantiveram-se estáveis durante o período de armazenamento.(AU)

El queso Quark es un queso de masa fresca obtenido por coagulación de la leche y acción principalmente de bacterias lácticas, obteniendo un queso de sabor refrescante. En su producción comercial se utiliza un cultivo iniciador específico para producción de quesos, en el presente trabajo esa cultura fue reemplazada por kéfir, un sistema simbiótico de bacterias del ácido láctico y levaduras, que se considera un producto probiótico. La inulina de agave es una fibra soluble considerada prebiótica con la capacidad de mejorar el equilibrio de la flora intestinal. El objetivo de esa investigación ha sido desarrollar queso Quark, usando kéfir como cultivo inicial y complementado con inulina de agave. Los quesos se produjeron por fermentación durante 24h / 25ºC seguido de drenaje del suero, en el queso suplementado con inulina se añadió 3%, después del drenaje del suero y se mantuvieron en macetas de plástico a temperatura de refrigeración hasta el momento del análisis, siendo que las microbiológicas, el pH y la acidez se realizaron a los 1, 7 y 14 días después de la fabricación. Los resultados de los análisis fisicoquímicos se mantuvieron cerca de los encontrados en la literatura. Los quesos mostraron altos conteos de Lactobacilli indicando su potencial probiótico, la adición de inulina de agave disminuyó el número de estos microorganismos, sin embargo, permanecieron en conteos altos. Se puede verificar que el uso de kéfir en la producción de queso Quark es factible, principalmente en las producciones artesanales, ya que por lo general es económico y de fácil manutención. Los lactobacilos se han mantenido estables durante el período de almacenamiento.(AU)

Abstract Soymilk was produced from vegetable soybean and fermented by probiotics (Lactobacillus acidophilus La-5, Bifidobacterium animalis Bb-12) in co-culture with Streptococcus thermophilus. The composition of the fermented beverage and oligosaccharides content were determined. The effect of fructooligosaccharides and inulin on the fermentation time and viability of probiotic microorganisms throughout 28 days of storage at 5 °C were evaluated. The soymilk from vegetable soybeans was fermented in just 3.2 h, when pH reached 4.8. Fermentation reduced the contents of stachyose and raffinose in soymilk. Prebiotics had no effect on acidification rate and on viability of B. animalis and S. thermophilus in the fermented beverage. The viable counts of B. animalis Bb-12 remained above 108 CFU mL-1 in the fermented soymilk during 28 days of storage at 5 °C while L. acidophilus La-5 was decreased by 1 log CFU mL-1. The fermented soymilk from vegetable soybeans showed to be a good food matrix to deliver probiotic bacteria, as well as a soy product with a lower content of non-digestible oligosaccharides.

BACKGROUND/AIMS: Non-alcoholic fatty liver disease (NAFLD) is one of the most prevalent chronic liver diseases in recent years. The aim of this study was to evaluate the effects of sitagliptin with and without a synbiotic supplement in the treatment of patients with NAFLD. METHODS: In total, 138 NAFLD patients aged 18-60 years were enrolled in the study. Patients were randomized to one of the following treatments for 16 weeks: Group I (n=68), sitagliptin 50 mg daily plus placebo (one capsule per day) or group II (n=70) sitagliptin 50 mg daily plus synbiotic (one capsule per day). Changes in fasting blood glucose (FBS), liver enzymes, lipid profile, and body mass index were compared between the groups. RESULTS: The mean change in FBS with sitagliptin-placebo from baseline was -10.47±5.77 mg/dL, and that with sitagliptin-synbiotic was -13.52±4.16 mg/dL. There was a significant difference between the groups (P < 0.001). The mean change in cholesterol (Chol) was -8.34±28.83 mg/dL with sitagliptin-placebo and -21.25±15.50 mg/dL with sitagliptinsynbiotic. There was a significant difference between the two groups (P=0.029). The administration of sitagliptin-placebo induced an increase of 6.13±27.04 mg/dL in low density lipoprotein (LDL), whereas sitagliptin-synbiotic induced a decrease of 14.92±15.85 mg/dL in LDL. A significant difference was observed between the two groups (P < 0.001). On the other hand, in the sitagliptin-synbiotic group, there was significant improvement in aspartate aminotransferase (AST) level compared to the sitagliptin-placebo group (P=0.018). CONCLUSIONS: Sitagliptin-synbiotic produced greater improvement in FBS, AST, Chol, and LDL compared to sitagliptin alone in patients with NAFLD.

PURPOSE: To evaluate the efficacy of synbiotic formula with partial whey hydrolysate and high magnesium content in infants presenting with functional constipation. METHODS: Sixty-five infants with functional constipation were included. Forty infants were treated during one month with parental reassurance and the intervention formula and were compared to a control group of 25 infants treated with parental reassurance only. Parents completed a quality of life (QoL) questionnaire at baseline and during the last week of the study. RESULTS: At inclusion, stool characteristics and QoL were similar in both groups. The control group was slightly older than the intervention group (7.5±3.9 vs. 6.2±3.6 weeks). At onset, stool composition was “hard and tight” (Bristol stool scale 1 and 2) in all infants. After one month, stool composition remained unchanged in the control group except in two infants that developed “creamy” stools (Bristol stool scale type 3 and 4). In the intervention group, stools remained “hard and tight” in 27.5%, and became “creamy” in 47.5%, “loose” (Bristol stool scale type 5) in 22.5% and “watery” (Bristol stool type 6 and 7) in 2.5%. The benefit of the intervention formula was estimated to be “very important” in 70%. The median scores for QoL improved significantly in the intervention group for all parameters and for one in the control group. CONCLUSION: The intervention formula significantly improved functional constipation resulting in a better QoL of the parents and infants.

ABSTRACT Objective: to evaluate the effect of perioperative administration of symbiotics on the incidence of surgical wound infection in patients undergoing surgery for colorectal cancer. Methods: We conducted a randomized clinical trial with colorectal cancer patients undergoing elective surgery, randomly assigned to receive symbiotics or placebo for five days prior to the surgical procedure and for 14 days after surgery. We studied 91 patients, 49 in the symbiotics group (Lactobacillus acidophilus 108 to 109 CFU, Lactobacillus rhamnosus 108 to 109 CFU, Lactobacillus casei 108 to 109 CFU, Bifi dobacterium 108 to 109 CFU and fructo-oligosaccharide (FOS) 6g) and 42 in the placebo group. Results: surgical site infection occurred in one (2%) patient in the symbiotics group and in nine (21.4%) patients in the control group (p=0.002). There were three cases of intraabdominal abscess and four cases of pneumonia in the control group, whereas we observed no infections in patients receiving symbiotics (p=0.001). Conclusion: the perioperative administration of symbiotics significantly reduced postoperative infection rates in patients with colorectal cancer. Additional studies are needed to confirm the role of symbiotics in the surgical treatment of colorectal cancer.

RESUMO Objetivo: avaliar o efeito da administração perioperatória de simbióticos na incidência de infecção de ferida operatória em pacientes operados por câncer colorretal. Métodos: ensaio clínico randomizado de pacientes com câncer colorretal submetidos à cirurgia eletiva e aleatoriamente designados para receberem simbióticos ou placebo por cinco dias antes do procedimento cirúrgico e por 14 dias após a cirurgia. Noventa e um pacientes foram estudados: 49 para o grupo de simbióticos (Lactobacillus acidophilus 108 a 109 UFC, Lactobacillus rhamnosus 108 a 109 UFC, Lactobacillus casei 108 a 109 UFC, Bifi dobacterium 108 a 109 UFC e fruto-oligosacarídeos (FOS) 6g) e 42 para o grupo placebo. Resultados: infecção de sítio cirúrgico ocorreu em um (2%) paciente no grupo de simbióticos e em nove (21,4%) pacientes no grupo controle (p=0,002). Três casos de abscesso intra-abdominal e quatro casos de pneumonia foram diagnosticados no grupo controle, enquanto não foram observadas tais infecções em pacientes que receberam simbióticos (p=0,001). Conclusão: a administração perioperatória de simbióticos reduziu significativamente as taxas de infecção pós-operatória em pacientes com câncer colorretal. Estudos adicionais são necessários para confirmar o papel dos simbióticos no tratamento cirúrgico do câncer colorretal.

In recent decades, special attention has been given to the potential association between the gut ecosystem and chronic diseases. Several features and complications of chronic kidney disease (CKD) may induce an unbalanced gut environment, leading to unfavorable consequences for a patient's health. The first section of this review is dedicated to a description of some aspects of gut microbiota and intestinal barrier physiology. The following section explores the impact of CKD on the gut ecosystem and intestinal barrier, particularly the association with uremic toxins, inflammation, and immunodeficiency. Finally, the review describes the state of the art of potential therapies with prebiotics, probiotics, and synbiotics employed to modulate the gut environment and to reduce the generation of colon-derived uremic toxins in CKD.

Com o objetivo de avaliar a qualidade dos ovos de codornas alimentadas com diferentes aditivos em duas fases de produção, 360 codornas foram distribuídas em um delineamento inteiramente ao acaso, em esquema de parcela subdividida no tempo (de nove até 23 e de 24 até 39 semanas de idade), com cinco tratamentos e oito repetições de nove aves cada, organizados da seguinte forma: controle, antibiótico, prebiótico, probiótico e simbiótico. As variáveis analisadas foram: unidade Haugh, índice de gema, porcentagem dos componentes do ovo, espessura de casca medida pelo micrômetro e pelo MEV. O fornecimento dos aditivos no segundo período aumentou a unidade Haugh e nos dois períodos avaliados proporcionou aumento da porcentagem de gema e de casca e da espessura da casca e de suas membranas. A inclusão dos aditivos foi mais eficiente em aumentar o peso dos ovos e a porcentagem de gema e de casca no segundo período. A espessura da casca (MEV) melhorou após inclusão de antibiótico e simbiótico na ração no segundo período. A inclusão de aditivos na ração melhora a qualidade dos ovos de codornas durante toda a fase produtiva. Antibiótico e simbiótico são mais eficazes em melhorar a espessura da casca dos ovos produzidos durante o segundo período produtivo.(AU)

To evaluate the quality of eggs of quails fed with different additives in two stages of the productive period, 360 quails were distributed in a completely randomized design in a split plot scheme in time (9 to 23 and 24 to 39 weeks of age) with five treatments and eight repetitions of nine birds each, organized as follows: control, antibiotic, prebiotic, probiotic, and symbiotic. The analyzed variables were: Haugh unit, yolk index, percentage of egg components, shell thickness measured by the micrometer and the SEM. The supply of additives in the second period increased Haugh units, and in both periods provided an increase in the percentage of yolk and shell and improved the thickness of the shell and its membranes. The inclusion of additives was more effective in promoting weight gain in eggs and the percentage of egg yolk and egg shell from 24 to 39 weeks of age. The shell thickness (SEM) improved after inclusion of antibiotic and symbiotic in feed in the second period. The addition of additives in food improved the quality of Japanese quail egg throughout the productive period. Antibiotics and symbiotics proved to be more effective in improving shell thickness of the eggs produced in the second productive period.(AU)

PURPOSE: The purpose of this paper is to evaluate the efficacy of a lactose- reduced synbiotic partial whey hydrolysate in formula fed infants presenting with colic and the impact of this dietary intervention in mean crying time and quality of life. METHODS: Forty infants with infantile colic were treated during one month with parental reassurance and the intervention formula (partial whey hydrolysate, reduced lactose, Bifidobacterium lactis BB12 and galacto-oligosaccharides) and were compared to a control group of 20 infants with infantile colic treated with parental reassurance and a standard infant formula. Parents completed a quality of life (QoL) questionnaire assessing the burden of infantile colic. Wilcoxon test, t-test and Mann-Whitney test were used to compare QoL scores before and after intervention as well as between the intervention and control group. RESULTS: At inclusion, duration of crying did not differ between both groups. Crying duration decreased with 2.7 hours (from 3.2 to 0.5 hours) in the intervention group while duration of crying decreased only with 1.2 hours in the control group (p<0.001). Stool composition became looser in the intervention group, but defecation frequency did not change. The median scores of the QoL questionnaire improved significantly in the intervention group for all parameters. In the control group, parameters improved significantly also but not for the parent-child and social interaction. The score changes were significantly greater in the intervention than in the control group. CONCLUSION: The intervention formula (partial whey hydrolysate, synbiotic, reduced lactose) significantly reduced the duration of crying and improved QoL of the parents and infants.
