OBJECTIVES: The eradication of Helicobacter (H.) pylori allows peptic ulcers in patients infected with the bacteria to be cured. Treatment with the classic triple regimen (proton pump inhibitor, amoxicillin and clarithromycin) has shown decreased efficacy due to increased bacterial resistance to clarithromycin. In our country, the eradication rate by intention to treat with this regimen is 83%. In Brazil, a commercially available regimen for bacterial eradication that uses levofloxacin and amoxicillin with lansoprazole is available; however, its efficacy is not known...

The occurrence of a hepatoduodenal ligament teratoma is extremely rare, with only a few cases reported in the literature. This case report describes the discovery of a hepatoduodenal ligament lesion revealed during abdominal ultrasonography for cholelithiasis-related abdominal pain in a 27-year-old female. Cross-sectional imaging identified a 5 cm × 4 cm heterogeneous mass of fat tissue with irregular calcification located in the posterior-superior aspect of the head of the pancreas. An encapsulated lesion showing no invasion to the common bile duct or adjacent organs and vessels was exposed during laparotomy and resected...

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 São Paulo. METHODS: Outpatients with uninvestigated dyspepsia, according to Rome III criteria, answered a dyspepsia questionnaire and underwent esophagogastroduodenoscopy...

BACKGROUND: The treatment for the eradication of Helicobacter pylori (H. pylori) is complex; full effectiveness is rarely achieved and it has many adverse effects. In developing countries, increased resistance to antibiotics and its cost make eradication more difficult. Probiotics can reduce adverse effects and improve the infection treatment efficacy.If the first-line therapy fails a second-line treatment using tetracycline, furazolidone and proton-pump inhibitors has been effective and low cost in Brazil; however it implies in a lot of adverse effects...

CONTEXT: The antibiotic susceptibility is the cornerstone for the eradication therapies of Helicobacter pylori. OBJECTIVES: To evaluate the prevalence of primary resistance of H. pylori was evaluated in an urban Brazilian population. METHODS: H. pylori isolates were obtained from patients submitted to an upper gastrointestinal endoscopy for the evaluation of dyspeptic symptoms. Biopsies from antrum, corpus and fundus were taken to determine the antibiotic susceptibility of H...

BACKGROUND: TREATMEN The contribution of eosinophilic esophagitis (EoE) to refractory gastroesophageal reflux disease (GERD) remains unknown. When EoE and GERD overlap, the clinical, endoscopic and histological findings are nonspecific and cannot be used to distinguish between the two disorders. Limited data are available on this topic, and the interaction between EoE and GERD is a matter of debate. AIM: We have conducted a prospective study of adult patients with refractory GERD to evaluate the overlap of reflux and EoE...

INTRODUCTION: The scheme proton pump inhibitor/amoxicillin/clarithromycin (PPI/AC) is still the first-line treatment for Helicobacter pylori (H. pylori) infections despite evidence suggesting its failure in up to 20% to 30% of patients. METHODOLOGY: This study involved 493 patients who were prescribed omeprazole (20 mg twice a day) or another proton pump inhibitor in equivalent dosage, amoxicillin (1 g twice a day), and clarithromycin (500 mg twice a day) for seven days...

Gastroesophageal reflux disease (GERD) is one of the most common disorders in medical practice. A number of guidelines and recommendations for the diagnosis and management of GERD have been published in different countries, but a Brazilian accepted directive by the standards of evidence-based medicine is still lacking. As such, the aim of the Brazilian GERD Consensus Group was to develop guidelines for the diagnosis and management of GERD, strictly using evidence-based medicine methodology that could be clinically used by primary care physicians and specialists and would encompass the needs of physicians, investigators, insurance and regulatory bodies...

BACKGROUND: The Helicobacter pylori reinfection seems to be higher in developing countries, than in developed ones. The aim of the study was to determine the annual recurrence rate of H. pylori, in Brazilian patients with peptic ulcer disease, in a 5-year follow-up. METHODS: Patients, with peptic ulcer disease diagnosed by upper digestive endoscopy (UDE) and H. pylori infection verified by histological analysis, rapid urease test, polymerase chain reaction, and urea breath test (UBT), were treated for bacterial eradication...

CONTEXT: Whether Helicobacter pylori infection is a protective or predisposing factor for the development of gastroesophageal reflux disease remains controversial. The most virulent strains, such as those expressing the cytotoxin-associated gene A (CagA), and the site of gastric colonization have been correlated with the prevention or development of esophagitis. AIM: To determine the incidence of erosive esophagitis following eradication of H. pylori in patients with peptic ulcer disease and to evaluate the association of erosive esophagitis with virulent strains of H...

BACKGROUND: Increasing resistance to clarithromycin and nitroimidazole is the main cause of failure in the Helicobacter pylori eradication. The ideal retreatment regimen remains unclear, especially in developing countries, where the infection presents high prevalence and resistance to antibiotics. The study aimed at determining the efficacy, compliance and adverse effects of a regimen that included furazolidone, levofloxacin and lansoprazole in patients with persistent Helicobacter pylori infection, who had failed to respond to at least one prior eradication treatment regimen...

BACKGROUND: The Brazilian consensus recommends a short-term treatment course with clarithromycin, amoxicillin and proton-pump inhibitor for the eradication of Helicobacter pylori (H. pylori). This treatment course has good efficacy, but cannot be afforded by a large part of the population. Azithromycin, amoxicillin and omeprazole are subsidized, for several aims, by the Brazilian federal government. Therefore, a short-term treatment course that uses these drugs is a low-cost one, but its efficacy regarding the bacterium eradication is yet to be demonstrated...

PURPOSE: Many of the currently used eradication regimens against Helicobacter pylori fail to cure the infection either due to antimicrobial resistance or to poor patient compliance. The infection leads to increased risk of developing potentially severe complications, such as gastric cancer. This study was aimed at assessing the efficacy and safety of a quadruple therapy with furazolidone for H. pylori retreatment. METHODS: Patients who had failed one or more eradication regimens against H...
