Abstract Objective: To analyze the composition of formulations of probiotics sold in establishments in the State of Tabasco or that can be purchased online. Materials and methods: A descriptive study in which formulations of probiotics sold in 21 establishments in the city of Villahermosa were identified and compared with 30 probiotic supplements sold online. Product information was organized in a database and analyzed according to the dosage form, probiotic genera, species/subspecies contained and their classification as probiotics or synbiotics and as drugs or supplements. Results: Thirty-one local products and 30 online products formulated with probiotics in 6 different dosage forms were analyzed. Only five local products and no online products are certified by COFEPRIS as drugs. Forty-eight percent of the formulations are monostrain and the rest are multistrain. Seventy-two percent of the formulations are probiotics and the rest are synbiotics. Among the 61 products analyzed, 46 species belonging to 13 different genera were identified, and 39% were common to local and online products. Many of products contain species of the Lactobacillus and Bifidobacterium genera. The genus Bacillus was the only genus that was never combined with other genera in the formulations analyzed in this study. Conclusions: The population of the state of Tabasco can find at least 31 formulations of probiotics in local establishments. The variety increases if we consider the dietary supplements available for sale online. Multistrain supplements are particularly abundant in online retailers. The products certified by COFEPRIS ensure that the benefits of the formulation are supported by clinical trials in humans and are manufactured following good manufacturing practices.

Role of probiotics and synbiotics on inhibiting Streptococcus mutans level in saliva of children A randomized controlled trial

Background: Probiotics and synbiotics through its direct and indirect interactions interferes with biofilm formation, competes with oral microorganisms thereby creating better oral health. Aim: This study aims to assess the effectiveness of Probiotics and Synbiotics on inhibiting Streptococcus mutans level in saliva of children after 15 days of daily intake of probiotic and synbiotic curd. Methodology: A double-blind randomized controlled trial was planned. Salivary samples at baseline were collected from forty children in the age group of 6–12 years who were divided into two groups of 20 each to receive probiotic and synbiotic curd respectively for 15 days. Salivary samples were collected after intervention and S. mutans levels were estimated. Statistical Analysis: The collected data were analyzed using Statistical Package for Social Sciences (SPSS) version 22. Intra- and inter-group comparison of mean S. mutans levels for both the groups were done using the paired and unpaired t-test respectively. The statistical significance was set at P ? 0.05. Results: A statistically significant reduction in salivary S. mutans counts was observed in both the groups after 15 days (P < 0.001). A significantly higher inhibition of S. mutans growth was present in the probiotic compared to synbiotic group (P < 0.001). Conclusion: Probiotics and Synbiotics were effective in inhibiting salivary S. mutans level of children. However, inhibition of S. mutans growth was found to be better in children who consumed Probiotic curd than the Synbiotic curd.

Microbiota intestinal, prebióticos, probióticos e simbióticos em doenças gastrointestinais e hepáticas: procedimentos de reunião conjunta da Sociedade Brasileira de Hepatologia (SBH), Núcleo Brasileiro de Estudos do Helicobacter pylori e Microbiota (NBEHPM) e Federação Brasileira de Gastroenterologia (FBG) / Gut microbiota, prebiotics, probiotics, and synbiotics in gastrointestinal and liver diseases: proceedings of a joint meeting of the brazilian society of hepatology (sbh), brazilian nucleus for the study of helicobacter pylori and microbiota (nbehpm), and brazilian federation of gastroenterology (fbg)

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.

A Comparative Clinical, Microbiological and Biochemical Evaluation of Guided Periodontal Pocket Recolonisation (GPR) using Synbiotics as an Adjunct to Scaling and Root Planing in Patients with Chronic Periodontitis: A Pilot Project

Background: With increase in the resistance to antibiotics, the paradigm of periodontal treatment in recent years is slowly shifting from specific bacteria elimination to altering bacterial ecology by probiotics. With this objective in mind, the present study was carried out to assess the use of a symbiotic preparation as a guided pocket recolonisation (GPR) procedure in patients with chronic periodontal disease. Materials and methods: Total 180 patients with chronic periodontitis with presence of true periodontal pockets; 4 mm-6 mm in depth involving minimum 3 or more quadrants were selected and divided into 3 groups wherein the first group only scaling and root planing was done without GPR application; in the 2nd group, GPR was carried out as a single application following SRP and in the 3rd group, multiple applications of GPR with SRP was done. Clinical measurements; microbiological analysis of periodontal pathogens by anaerobic culture and biochemical assessment of alkaline phosphatase and interleukin-6 using ELISA and spectrophotometry was carried out at baseline, 3 and 6 months respectively. Results: All the 3 groups showed significant changes in clinical (p<0.05) as well as in microbiological and biochemical parameters (p<0.05) within the groups. Intergroup comparisons revealed significant changes in group 2 and 3 with biochemical parameters. Positive correlation was observed with clinical parameters and alkaline phosphatase levels and P. intermedia counts in group 1 and 3. Conclusion: Within the limitations of the present study, it could be concluded that symbiotic therapy may have some additional benefit to Scaling and root planing.

Short-term effect of a synbiotic in salivary viscosity and buffering capacity; a quasi-experimental study / Efecto a corto plazo de un simbiótico en la viscosidad y la capacidad tampón salival; un estudio cuasi experimental

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.

Efeitos da suplementação com simbióticos sobre a função intestinal e a inflamação sistêmica de idosos inseridos na comunidade - análises secundárias de um estudo clínico-randomizado / Effects of synbiotic supplementation on gut functioning and systemic inflammation of community-dwelling elders - secondary analyses from a randomized clinical trial

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.

The world of synbiotics: a review of literature and clinical evidence in diarrhoea from the lens of a paediatrician

The use of synbiotics in the management of acute diarrhoea in children is becoming a common practice in India. However, since this is an upcoming modality of treatment, it is essential to review the scientific rationale and evidence on clinical efficacy and safety in the context of paediatric diarrhoea. In addition, most synbiotics contain a combination of multiple probiotics along with a prebiotic. Thus arises, a parallel need to understand whether a combination of probiotics performs better than single probiotics, hence justifying the rationale for such combinations. A review of available evidence suggests that synbiotics are indeed safe and superior in efficacy to single probiotics (like Bacillus clausii, Lactobacillus rhamnosus GG etc) and that there is a good body of evidence to support the efficacy and tolerability of synbiotics in the management of paediatric acute gastroenteritis. There is also evidence to suggest that combination probiotics have superior benefits compared to single probiotics, thus justifying their use as part of synbiotics. The overall benefits of synbiotics reported in various clinical trials on paediatric diarrhoea include, a rapid normalization of the gastrointestinal flora, a reduction in the duration of diarrhoea, quicker improvement in stool consistency, lesser administration of additional medications like antibiotics, antiemetics and antipyretics, higher physician reported treatment satisfaction scores and enhanced overall efficacy against gastrointestinal pathogens, including diarrhoea of rota virus origin. Hence, synbiotics put up a strong case to look beyond probiotics and single probiotic formulations in paediatric diarrhoea.

A Randomized Clinical Trial of Synbiotics in Irritable Bowel Syndrome: Dose-Dependent Effects on Gastrointestinal Symptoms and Fatigue / 가정의학회지

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.

Effect of Synbiotic on the Treatment of Jaundice in Full Term Neonates: A Randomized Clinical Trial / 대한소아소화기영양학회지

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.

The influence of probiotics and synbiotics on intestinal inflammation and microbiota in mice with acute colitis / 中华内科杂志

Objective To investigate the effects of probiotics and synbiotics on inflammation and microbiota of acute colitis in mice.Methods C57BL/6J mice were divided into 4 groups randomly.Each group had 10 mice and was given 2.5％ dextran sulfate sodium (DSS) drinking water for 5 days other than the blank control group.Except for model control group,other two groups were administrated with probiotics and synbiotics,respectively.Probiotics was composed of Lactobacillus acidophilus,Lactobacillus rhamnosus and Bifidobacterium lactis,while synbiotics was composed of the aforementioned probiotics,inulin and galactooligosaccharide.Feces of different periods and mucosa samples were collected to analyze the differences of enteric flora by 16s rDNA sequencing.Results (1) Pathological scores in probiotics group and synbiotics group were 5.40±2.79 and 7.25±2.87,respectively,which were significantly lower than those in the model control group with scores 27.00 ± 7.94.Model control group,probiotics group and synbiotics group showed lower flora diversity,increased Bacteroides and decreased Faecalibacterium than blank control group.The mucosal microbiota was different from fecal flora in abundance and species for each group,and Mucispirillum was more common in mucosa.Conclusions Probiotics and synbiotics alleviate the inflammation of acute colitis in mice.Imbalance of beneficial genera to harmful genera is the characteristic of acute colitis.Supplementation of probiotics and synbiotics contributes to regulating the balance of intestinal microbiota.

Effects of synbiotics on ileal microbiota

Background & objectives: Despite advancements in molecular-based methods, the composition of the human ileal microbiota and the effects of synbiotics/probiotics on its microbes remain poorly understood. The aim of this study was to determine the composition of the mucus microbiota in the human ileum and to assess the effects of oral administration of synbiotics on the microbiota. Methods: As part of a clinical trial for synbiotics treatment and surgical infection, ileal mucus was sampled when resection of the ileocecal portion was required. The microbiota composition was examined using 16S rRNA-targeted real-time-quantitative polymerase chain reaction. Results: A total of 33 samples from the synbiotics group and 39 from the control group were analyzed. Total numbers of bacteria in the ileum were 108.5 cells/g in the synbiotics group and 108.4 cells/g in the control group, in which obligate anaerobes were dominant over facultative anaerobes. The level of Enterobacteriaceae was significantly lower in the synbiotics group than in the control group. The administered probiotics species Lactobacillus casei strain Shirota and Bifidobacterium breve strain Yakult were detected in 42 and 76 per cent of the synbiotics group, respectively. No significant correlations were observed between tumour stage/size and the various microbes present, except for a negative correlation between tumour size and Bifidobacterium. Interpretation & conclusions: The present analysis of a substantial number of samples from surgically resected intestines showed an abundance of obligate anaerobes as a characteristic feature of the ileal mucus microbiota. Our results also indicated that the synbiotics intervention induced a prominent reduction in Enterobacteriaceae in the ileal microbiota.

Perioperative synbiotics administration decreases postoperative infections in patients with colorectal cancer: a randomized, double-blind clinical trial / A administração perioperatória de simbióticos em pacientes com câncer colorretal reduz a incidência de infecções pós-operatórias: ensaio clínico randomizado duplo-cego

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.

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.

Effects of early enteral nutrition combined with synbiotics on CRP and PCT in patients with severe head injure / 肠外与肠内营养

Objective:To evaluate the effect of early enteral nutrition supplemented with synbiotics on the levels of C reactive protein (CRP) and Procalcitonin(PCT)level of patients with severe brain injury.The clinical outcomes were also observed.Methods:Forty-seven patients with identified severe brain injury were randomized into study group (n =24) and control group (n =23).All patients received enteral nutrition via nasogastric tube within 24 to 48 h following admission.Patients in the study group were also given synbiotics.Fasting blood samples were collected for detecting the levels of CRP,PCT on day 1,4,7 and 15,respectively.The incidence of lung infection,the length of ICU stay,the cost,the GCS score,the APACHE Ⅱ score,and the mortality in 30 days after administration were collected and compared between 2 groups.Results:Patients in the study group had a lower level of PCT than control group on day 7 and 15 (P ＜0.05,P ＜0.05),and a lower level of CRP on day 15 (P ＜0.01)was also found in the study group.The incidence of lung infection of the study group was also significantly lower than the control group (P ＜ 0.05).A reduced length of hospital stay and a lower cost were found in the study group (P ＜0.05).The GCS scores in the study group was higher on day 15 when compared with that in the control group (P ＜ 0.05).However,There was no significant change in APACHE Ⅱ score and mortality in 30 days(P ＞ 0.05).Conclusion:Nutrition supplemented with synbiotics leads to a lower rate of infection,a shorter length of ICU stay,a reduced the cost,and a better outcome in patients with severe brain injury.

Synbiotics adjust intestinalmicroecology to treat rat NASH and its effect on TLR4 / 基础医学与临床

Objective To observe the change of intestinal microflora on the process of nonalcoholic steatohepatitis(NASH),and to explore the synbiotics therapeutic effect on NASH.Methods Rats were administrated with high fat diet to establish NASH model.In the process of NASH rats modeling,the level of triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), low density lipoprotein (LDL), fasting blood sugar (FBS) and fasting insulin (FINS) was dynamically tested by automatic biochemical analyzer.The change of main intestinal flora was detected by 16 S rRNA fluorescence quantitative polymerase chain reaction.NAFLD activity score was calculated.HE staining was used to observe the hepaticpathological changes and the TLR4 expression was detected by using enzyme-linked immunosorbent assay and immunohistochemical method.Until the 4th,8th,10th weekin the process of NASH modeling, 10 rats were feeded with synbiotics for 2 weeks, and all of above indicators were tested and observed.Results 1)With the extension of a high-fat diet feeding time, the degree of hepatocyte steatosis obviously increased.NAFLD score was significantly heightened(P<0.01).2)Number of independent activities of rats significantly increased, the serological level of TG, TC, LDL, FBS and FINS were lower significantly after intervention with synbiotics for 2 weeks(P<0.05).3)Synbiotics intervention for two weeks significantly increased the amount of bifidobacterium and lactobacillus and decrease the amount of enterococcus significantly(P<0.05).4)The expression of TLR4 was gradually increased in the process of NASH rats modeling(P<0.05),but decreased after 2 weeks of the synbiotics-intervention (P<0.05).Conclusions Intestinal microecology change is closely related to the development of NASH,therefor, synbiotics could improve the quality of life and biochemical indicators of NASH rats through adjusting intestinal microecology and the expression level of TLR4 protein might been involved.

Safety of a New Synbiotic Starter Formula / 대한소아소화기영양학회지

PURPOSE: Breastfeeding is the best way to feed all infants, but not all infants can be (exclusively) breastfed. Cow's milk based infant formula is the second choice infant feeding. METHODS: The safety of a new synbiotic infant formula, supplemented with Bifidobacterium lactis and fructo-oligosaccharides, with lactose and a whey/casein 60/40 protein ratio was tested in 280 infants during 3 months. RESULTS: The median age of the infants at inclusion was 0.89 months. Weight evolution was in accordance with the World Health Organization growth charts for exclusive breastfed infants. The evolution of all anthropometric parameters (weight-for-length z score and body mass index-for-age z score) was within the normal range. The incidence of functional constipation (3.2%), daily regurgitation (10.9%), infantile crying and colic (10.5%) were all significantly lower than the reported median prevalence for a similar age according to literature (median value of 7.8% for functional constipation, 26.7% for regurgitation, 17.7% for infantile colic). CONCLUSION: The new synbiotic infant starter formula was safe, resulted in normal growth and was well tolerated. Functional gastro-intestinal manifestations (functional constipation, regurgitation and colic) were significantly lower than reported in literature. Synbiotics (Bifidobacterium lactis and fructo-oligosaccharides) in cow's milk based infant formula bring the second choice infant feeding, formula, closer to the golden standard, exclusive breastfeeding.

Microbiota intestinal y ácidos grasos de cadena corta en pacientes críticos / Gut Microbiota and Short-Chain Fatty Acids in Critically Ill Patients

Resumen Antecedentes: diversos estudios han mostrado cambios en la microbiota intestinal (MI) y los ácidos grasos de cadena corta (AGCC) en pacientes críticos con síndrome de respuesta inflamatoria sistémica (SRIS). Objetivo: revisar la evidencia sobre el papel de la MI y los AGCC en pacientes críticos y su modulación con prebióticos, probióticos y simbióticos. Materiales y métodos: búsqueda de artículos en bases de datos bibliográficas Pubmed, Science Direct, Ovid, Medline y Scopus, utilizando como descriptores microbiota, paciente crítico, unidad de cuidados intensivos, síndrome de respuesta inflamatoria sistémica, ácidos grasos de cadena corta, probióticos, prebióticos y simbióticos. Resultados: la MI en pacientes críticos está disminuida tanto en número de bacterias como en diversidad, lo cual puede resultar en una desregulación de la respuesta inmune sistémica ante la invasión de microorganismos patógenos. Los cambios en los AGCC en pacientes críticos se atribuyen a una disminución de bacterias anaerobias obligadas y sustratos de fermentación necesarios para su producción. La modulación de la MI con probióticos, prebióticos y simbióticos sugiere mejoría en la función intestinal. Conclusiones: la MI y los AGCC en pacientes críticos se encuentran alterados, de ahí que mantener el equilibrio en el entorno intestinal probablemente desempeñe una función clave para disminuir complicaciones y mejorar su pronóstico.

Abstract Background: Different studies have shown changes in gut microbiota and short-chain fatty acids in critically ill patients with Systemic Inflammatory Response Syndrome (SIRS). Aim: To review the evidence about the role of gut microbiota and SCFAs in critically patients and its modulation with prebiotics, probiotics and symbiotic. Materials and Methods: A search of the literature in Pubmed, Science Direct, Ovid, Medline and Scopus databases was conducted. The terms used were microbiota, critically ill, intensive care unit, systemic inflammatory response syndrome, short-chain fatty acids, prebiotics, probiotics and symbiotic. Results: The intestinal microbiota in critically ill patients is reduced in number and diversity, which can lead to dysregulation of the systemic immune response to the pathogenic invasion. Changes in SCFAs in critically ill patients are attributed to a decrease of obligate anaerobic bacteria and the fermentation substrates required for its production. The gut microbiota modulation with prebiotics, probiotics and symbiotic suggest improvement in bowel function. Conclusions: Gut microbiota and SCFAs are altered in critically ill patients; therefore, maintaining the intestinal environment is key for reducing complications and improving prognosis.

Objective To investigate the effect of early enteral nutrition combined with synbiotics agents on normal intestinal flora,fecal SIgA and infectious complications in patients with hypertensive intracerebral hemorrhage.Methods Fifty-three patients with hypertensive intracerebral hemorrhage were randomly divided into early enteral nutrition group (control group,n =26) and early enteral nutrition combined with synbiotics group (study group,n =27).The patients in control group started receiving enteral nutrition (RuiSu) within 24 to 48 hours after injury ; Patients in study group received a enteral nutritional support which as well as control group,but added synbiotics (Golden Bifid) in the first 14 days of enteral nutritional support.Stool specimens were Collected on day 0,day 4,day 8,day 15 of enteral nutrition support for quantitative analysis of normal intestinal flora and detection of stool SIgA through enzyme-linked immunosorbent assay.The difference of two groups in infectious complications were observed.Results On nutritional support day 8 and day 15,escherichia coli (P =0.004,P =0.004) and enterococci (P =0.032,P =0.048) expression were lower in study group than the control group,bifidobacteria (P =0.046,P =0.024) expression were higher in study group than the control group.During the study period lactobacillus,bacteroides and clostridium were no statistically significant between the two groups (P ＞ 0.05).Fecal SIgA expression in study group was higher than control group (P =0.035) on nutritional support dayl5.The incidence of infectious complications in study group was lower than the control group (33.33％ vs.46.15％),but there was no significant difference (P =0.230).Conclusion compared with ordinary enteral nutrition,enteral nutrition combined with synbiotics agents can be effective in improving intestinal flora imbalance and increase intestinal immune function in patients with hypertensive intracerebral hemorrhage.

Diet and functional foods in treatment and maintenance therapy of colon disorders.

Dietary habits have been associated with variations in the risk of colon disorders, either its increase or decrease. Colon-specific approaches showed their potential to target and treat colon cancers and inflammatory diseases, but they vary in success rates for local recurrence, disease-free survival, and overall survival. Also, chemotherapies and radiotherapies have been applied as the surgical adjuvant treatments. The significant role of exogenously administered Lactobacilli in reducing toxin-producing bacteria in the gut and increases the longevity of the host, led to the coining of the term ‘probiotics’. The evidence on the effects of inulin and oligofructose on colonization, translocation of pathogens and the prevention of intestinal diseases make them suitable candidates to treat colon disorders. Among potentially protective foods, growing attention has been dedicated to functional foods comprising probiotics, such as Lactobacilli or Bifidobacteria, and prebiotics such as fructooligosaccharides or fructans, as their consumption may treat inflammatory bowel diseases, like ulcerative colitis, crohn’s disease as well as experimentally induced colon cancer in mammals. The readily apparent synergy of concomitantly using beneficial microorganisms and nutritive materials that support their growth led to the term “synbiotics” to describe foods or supplements that combine both probiotics and prebiotics. Various potential mechanisms are addressed in the present paper. This article discusses the real value of dietary components, which offers practical information to help patients as well as health professionals. Furthermore, article has focused on the possible value of probiotics, prebiotics and synbiotics in treatment and maintenance therapy of colonic ailments.

Prospectus of probiotics in modern age diseases

In India food reflects the warmth, hospitality, status, symbol of wealth and aesthetics. The synergistic combination of pre and probiotics is known as synbiotics. Regular consumption of synbiotics in diets imparts health benefits like improved immune response, maintain intestinal integrity, decrease intestinal infections and down regulate the allergic response, influence digestion and gastric motility. Because of the changes in life styles due to globalization, unhealthy diets, lack of physical activity and exposure to tobacco smoke or harmful use of alcohol non communicable diseases are disproportionately affecting the 80% of low and middle income countries. This review covers the mechanism of probiotic action, use of probiotics in treatment and prevention of diseases of modern age, progress in delivery systems for the administration and finally some regulatory considerations. In conclusion, combined skills of the microbiologist, food technologist and clinician are necessary to sustain effect of probiotics. The role of probiotic organisms as alternative or complementary therapy in combating a large number of disorders can be achieved with balance and healthy life style as well as clean external environmental conditions. It is hoped that more detailed research will be conducted regarding the efficacy of probiotics so that clinically well documented and simplest formulation will be developed and can be regarded as effective for everyone. With validated results strong market will be formed and expanded in near future.
