    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.

    Influence of exercise testing in gastroesophageal reflux in patients with gastroesophageal reflux disease
    (2014) MENDES-FILHO, Antonio Moreira; MORAES-FILHO, Joaquim Prado Pinto; NASI, Ary; EISIG, Jaime Natan; RODRIGUES, Tomas Navarro; BARBUTTI, Ricardo Correa; CAMPOS, Josemberg Marins; CHINZON, Decio
    Background : Gastroesophageal reflux disease is a worldwide prevalent condition that exhibits a large variety of signs and symptoms of esophageal or extra-esophageal nature and can be related to the esophagic adenocarcinoma. In the last few years, greater importance has been given to the influence of physical exercises on it. Some recent investigations, though showing conflicting results, point to an exacerbation of gastroesophageal reflux during physical exercises. Aim : To evaluate the influence of physical activities in patients presenting with erosive and non erosive disease by ergometric stress testing and influence of the lower esophageal sphincter tonus and body mass index during this situation. Methods : Twenty-nine patients with erosive disease (group I) and 10 patients with non-erosive disease (group II) were prospectively evaluated. All the patients were submitted to clinical evaluation, followed by upper digestive endoscopy, manometry and 24 h esophageal pH monitoring. An ergometric testing was performed 1 h before removing the esophageal pH probe. During the ergometric stress testing, the following variables were analyzed: test efficacy, maximum oxygen uptake, acid reflux duration, gastroesophageal reflux symptoms, influence of the lower esophageal sphincter tonus and influence of body mass index in the occurrence of gastroesophageal reflux during these physical stress. Results : Maximum oxigen consumption or VO 2 max, showed significant correlation when it was 70% or higher only in the erosive disease group, evaluating the patients with or without acid reflux during the ergometric testing (p=0,032). The other considered variables didn't show significant correlations between gastroesophageal reflux and physical activity (p>0,05). Conclusions : 1) Highly intensive physical activity can predispose the occurrence of gastroesophageal reflux episodes in gastroesophageal reflux disease patients with erosive disease; 2) light or short sessions of physical activity have no influence on reflux, regardless of body mass index; 3) the lower esophageal sphincter tonus does not influence the occurrence of reflux disease episodes during exercise testing.

    Probiotics intake and metabolic syndrome: A proposal (Retracted article. See vol. 39, pg. 85, 2014)
    (2011) BOGSAN, Cristina Stewart B.; FLORENCE, Ana Carolina R.; PERINA, Natalia; BARBUTI, Ricardo C.; NAVARRO-RODRIGUEZ, Tomas; EISIG, Jaime N.; OLIVEIRA, Marice N.
    Probiotics are practical tools to provide the modulation of microbiota. The ingestion of food or ingredients containing anti-inflammatory activity components as probiotics should be useful in obesity control and associated co-morbidities treatment. Metabolic syndrome is a metabolic dysfunction associated with visceral obesity and insulin resistance, in which the alterations in host microbiota interactions play an important role. Besides diet and physical activity, new strategies are necessary to control metabolic syndrome, and as consequence improving quality of life. This article revises the actual knowledge concerning probiotic intake and obesity as a proposal to control metabolic syndrome.

    ASSESSMENT OF THE INTESTINAL MICROBIOTA IN ADULTS WITH EROSIVE ESOPHAGITIS
    (2021) BAIMA, Diego Cardoso; CARVALHO, Nayara Salgado; BARBUTI, Ricardo Correa; NAVARRO-RODRIGUEZ, Tomas
    ABSTRACT BACKGROUND: The intestinal microbiota influences the appropriate function of the gastrointestinal tract. Intestinal dysbiosis may be associated with a higher risk of esophageal lesions, mainly due to changes in gastroesophageal motility patterns, elevation of intra-abdominal pressure, and increased frequency of transient relaxation of the lower esophageal sphincter. OBJECTIVE: The aim of this study was to evaluate the intestinal microbiota in individuals with erosive esophagitis and in healthy individuals using metagenomics. METHODS: A total of 22 fecal samples from adults aged between 18 and 60 years were included. Eleven individuals had esophagitis (eight men and three women) and 11 were healthy controls (10 men and one woman). The individuals were instructed to collect and store fecal material into a tube containing guanidine solution. The DNA of the microbiota was extracted from each fecal samples and PCR amplification was performed using primers for the V4 region of the 16S rRNA gene. The amplicons were sequenced using the Ion Torrent PGM platform and the data were analyzed using the QIIME™ software version 1.8. Statistical analyses were performed using the Mann-Whitney non-parametric test and the ANOSIM non-parametric method based on distance matrix. RESULTS: The alpha-diversity and beta-diversity indices were similar between the two groups, without statistically significant differences. There was no statistically significant difference in the phylum level. However, a statistically significant difference was observed in the abundance of the family Clostridiaceae (0.3% vs 2.0%, P=0.032) and in the genus Faecaliumbacterium (10.5% vs 4.5%, P=0.045) between healthy controls and esophagitis patients. CONCLUSION: The findings suggest that reduced abundance of the genus Faecaliumbacterium and greater abundance of the family Clostridiaceae may be risk factors for the development of erosive esophagitis. Intervention in the composition of the intestinal microbiota should be considered as an adjunct to current therapeutic strategies for this clinical condition.

    Endoscopic findings in uninvestigated dyspepsia
    (2014) FAINTUCH, Jacob Jehuda; SILVA, Fernando Marcuz; NAVARRO-RODRIGUEZ, Tomas; BARBUTI, Ricardo Correa; HASHIMOTO, Claudio Lyoiti; ROSSINI, Alessandra Rita Asayama Lopes; DINIZ, Marcio Augusto; EISIG, Jaime Natan
    Background: It is important to know the causes of dyspepsia to establish the therapeutic approach. Dyspepsia is a frequent syndrome in our country, where there are restrictions to endoscopy and high prevalence of Helicobacter pylori (H. pylori) infection. This study aimed to assess the endoscopic findings of the syndrome, in an outpatient screening clinic of a tertiary hospital in Sao Paulo. Methods: Outpatients with uninvestigated dyspepsia, according to Rome III criteria, answered a dyspepsia questionnaire and underwent esophagogastroduodenoscopy. The Rapid Urease Test was applied to fragments of the antral mucosa and epidemiological data were collected from the studied population. Organic dyspepsia findings were analyzed with different variables to verify statistically significant associations. Results: Three hundred and six patients were included and 282 were analyzed in the study. The mean age was 44 years and women comprised 65% of the sample. Forty-five percent of the patients reported alarm symptoms. Functional dyspepsia was found in 66% of the patients (20% with normal endoscopy results and 46% with gastritis), 18% had GERD and 13% had ulcers (duodenal in 9% and gastric in 4%). Four cases of gastric adenocarcinoma were identified (1.4%), one without alarm characteristics, 1 case of adenocarcinoma of the distal esophagus and 1 case of gastric lymphoma. The prevalence of H. pylori was 54% and infection, age and smoking status were associated with organic dyspepsia. The age of 48 years was indicative of alarm signs. Conclusions: The endoscopic diagnosis of uninvestigated dyspepsia in our setting showed a predominance of functional disease, whereas cancer was an uncommon finding, despite the high prevalence of H. pylori. Organic dyspepsia was associated with infection, age and smoking status.

    Low levels of adherence with proton pump inhibitor therapy contribute to therapeutic failure in gastroesophageal reflux disease
    (2012) DAL-PAZ, K.; MORAES-FILHO, J. P.; NAVARRO-RODRIGUEZ, T.; EISIG, J. N.; BARBUTI, R.; QUIGLEY, E. M. M.
    To assess adherence to proton pump inhibitor (PPI) treatment and associated variables in patients with gastroesophageal reflux disease (GERD). Cross-sectional and prospective comprising 240 consecutive adult patients, diagnosed with GERD for whom continuous use of standard or double dose of omeprazole had been prescribed. Patients were ranked as ne-GERD (162: 67.5%) or e-GERD classified according to the Los Angeles classification as A (48:20.0%), B (21:8.6%), C (1:0.5%), D (1:0.5%), and Barrett's esophagus (7:2.9%). The Morisky questionnaire was applied to assess adherence to therapy and a GERD questionnaire to assess symptoms and their impact. Adherence was correlated with demographics, cotherapies, comorbidities, treatment duration, symptoms scores, endoscopic findings, and patient awareness of their disease. 126 patients (52.5%) exhibited high level of adherence and 114 (47.5%) low level. Youngers (P= 0.002) or married (O.R. 2.41, P= 0.03 vs. widowers) patients had lower levels of adherence; symptomatic patients exhibited lower adherence (P= 0.02). All other variables studied had no influence on adherence. Patients with GERD attending a tertiary referral hospital in Sao Paulo exhibited a high rate of low adherence to the prescribed PPI therapy that may play a role in the therapy failure. Age <60 years, marital status and being symptomatic were risk factors for low adherence.
