Background: The inherent complications of cirrhosis include protein-calorie malnutrition and micronutrient deficiencies.Changes in taste are detrimental to the nutritional status, and the mechanism to explain these changes is not well documented in the cirrhotic patients. Objective: To evaluate the taste buds of cirrhotic rats. Methods: Fourteen male Wistar rats were evaluated. After 16 weeks, the liver was removed to histologically diagnose cirrhosis, and blood was collected to perform liver integrity tests...

Background: A multitude of endoscopic findings post-gastric bypass procedures have been previously reported in the literature, but to our knowledge, no present rules exist that could guide clinicians regarding which findings should be actively sought, once an initial finding is identified. Objective: To identify co-occurrence patterns among endoscopic findings of patients having undergone past gastric bypass procedure. Methods: Our registry involves all consecutive patients undergoing an upper endoscopic evaluation after a gastric bypass procedure...

Background: Celiac disease is a permanent intolerance induced by gluten, which is expressed by T-cell mediated enteropathy, and has a high prevalence in the general population. There is evidence of a strong genetic predisposition to celiac disease. Objective: To determine the prevalence of genetic markers HLA-DQ2 and HLA-DQ8 in blood donors from São Paulo and measure human recombinant tissue transglutaminase antibody IgA class in HLA-DQ2 and HLA-DQ8 positive donors...

Background: Allergic proctocolitis is a disease that affects infants in the first months. The change in feed is the primary factor for clinical improvement and maintenance of the nutritional status of the infant. Objective: Study the anthropometric evolution of infants with allergic proctocolitis at diagnosis and 1 to 6 months after nutritional intervention. Methods: A retrospective cohort of infants with allergic proctocolitis diagnosis followed at the Pediatric Gastroenterology Institute of São Paulo (IGASTROPED), Brazil...

Background: The efficacy of nonselective β-blocker and endoscopic procedures, such as endoscopic variceal ligation, as primary prophylaxis of variceal hemorrhage in cirrhotic adults was demonstrated by numerous controlled trials, but in pediatric population, few are the number of studies. Objective: The objective of this study is to evaluate the primary prophylaxis with β-blocker in cirrhotic children and adolescents with portal hypertension. Methods: This is a cohort study encompassing 26 cirrhotic patients...

Background: Patients with liver disease often present protein-energy malnutrition. The assessment of food intake is very important in the investigation regarding the "health-disease" process. Objective: To assess dietary intake of cirrhotic patients through food record during 3 days, correlating it with the nutritional status of the patient and the stage of the disease. Methods: Cirrhotic outpatients from the Santa Casa de Misericórdia Hospital, RS, Brazil, were assessed...

Background: Due to the high prevalence of co-infection by hepatitis C virus (HCV) and human immunodeficiency virus (HIV) and the severity of these infections, the understanding of the biological mechanisms involved in these processes, including viral behavior and host genetic profile, is of great importance for patient treatment and for public health policies.Some single nucleotide polymorphisms (SNPs) in the human genome, such as the SNP rs1045642 (C3435T) in the MDR1 gene, have been reported to be associated to the sustained virological response (SVR) to HCV treatment in HCV-HIV co-infected patients...

Background: Anal sphincter tone is routinely assessed by digital rectal examination in patients with fecal incontinence, although its accuracy in detecting sphincter defects or separating competent from incompetent muscles has not been established. Objective: In this setting, we aimed to evaluate the accuracy of digital rectal examination in grading anal defects in order to separate small from extensive cases as depicted on 3D endoanal ultrasound, using a scoring sphincter defect and correlate anal tone to anal pressures...

Background: Since Chagas disease has esophageal manifestations with different degrees of involvement, the best surgical option is controversial, especially for patients with advanced chagasic megaesophagus and recurrent symptoms after previous treatment. Objective: To assess the early and late outcomes of esophagocardioplasty in a series of patients with advanced recurrent chagasic megaesophagus. Methods: This descriptive study included 19 older patients with recurrent megaesophagus grade III/IV and positive immunofluorescence for Chagas disease...

Background: Primary hypolactasia is a common condition where a reduced lactase activity in the intestinal mucosa is present. The presence of abdominal symptoms due to poor absorption of lactose, which are present in some cases, is a characteristic of lactose intolerance. Objective: Evaluate the efficacy of a product containing exogenous lactase in tablet form compared to a reference product with proven effectiveness in patients with lactose intolerance. Methods: Multicentre, randomized, parallel group, single-blind, comparative non-inferiority study...

Background: Helicobacter pylori has a worldwide distribution and is associated with the pathogenesis of various diseases of the digestive system. Treatment to eradicate this microorganism involves the use of a combination of antimicrobials, such as amoxicillin, metronidazole, clarithromycin, and levofloxacin, combined with proton pump inhibitors. Although the current therapy is effective, a high rate of treatment failure has been observed, mainly because of the acquisition of point mutations, one of the major resistance mechanisms developed by H...

The main objectives of clinical therapy in Crohn's disease are clinical and endoscopic remission without the use of corticosteroids for long periods of time, prevention of hospitalization and surgery, and improvement of quality of life. The main limitation of drug therapy is the loss of response over the long term, which makes incorporation of new drugs to the therapeutic arsenal necessary. This review analyses the main drugs currently used in clinical treatment of Crohn's disease.

BACKGROUND: Fatigue is a common complaint in patients with liver disease and may be considered a disabling symptom, affecting their quality of life and mental health. The Brazilian version of the Fatigue Severity Scale showed sensitivity to assess fatigue in some populations, but has not been tested in cirrhotic individuals. OBJECTIVE: The aim of this study was to evaluate the reliability of the Fatigue Severity Scale and association with depression and quality of life in patients with liver cirrhosis...

BACKGROUND: - Adequate bowel preparation is critical for the quality of colonoscopy. Despite reported occurrence of colonic explosion due to methane and hydrogen production by bacterial fermentation during colonoscopy, gas exchange during the procedure is believed to be effective in lowering existing methane concentration, allowing for safe utilization of mannitol for bowel preparation. Thus, mannitol is widely used for bowel cleansing prior to colonoscopy, considering its low cost and effectiveness for bowel preparation...

BACKGROUND: Endoscopic treatment of superficial gastrointestinal tumors is routinely performed, however the advantages and shortcomings of submucosal pressure-jet dissection is still debated. OBJECTIVE: - Aiming to compare this technique with conventional submucosal dissection, a study was designed in pigs. METHODS: - Areas of the antral mucosa of the stomach with a diameter of 2 cm2 (6 per animal) were marked, and resected by means of the hybrid-knife (experimental technique), and Flush-knife or IT-knife (controls)...

Maristella de Araújo Carvalho Sousa, Raymundo Paraná, Luís Jesuíno de Oliveira Andrade
BACKGROUND: - Exposure to viral antigens that share amino acid sequence similar with self- antigens might trigger autoimmune diseases in genetically predisposed individuals, and the molecular mimicry theory suggests that epitope mimicry between the virus and human proteins can activate autoimmune disease. OBJECTIVE: - The purpose of this study is to explore the possible sequence similarity between the amino acid sequences of thyroid self-protein and hepatitis C virus proteins, using databanks of proteins and immunogenic peptides, to explain autoimmune thyroid disease...
