38. Proposal of treatment algorithm for immune thromocytopenia in adult patients of a hematology service at a referral center in Northeastern Brazil
ABSTRACT Introduction: The management of adult (≥18 years) immune thrombocytopenia patients relies on platelet count, the risk of bleeding and presence of bleeding. Objective: Confirming the diagnosis of immune thrombocytopenia and the start of therapy, our hematology service, a referral center, favors the establishment of this algorithm to treat those p

39. GENDER, AGE, ENDOSCOPIC FINDINGS, UREASE AND HELICOBACTER PYLORI: ALL UNCORRELATED WITHIN A SAMPLE OF A HIGH GASTRIC CANCER PREVALENCE POPULATION IN AMAZON
RESUMO CONTEXTO: É amplamente assumido que gênero, idade, gastrite e Helicobacter pylori , todos têm algum grau de correlação e, portanto, podem sinergicamente levar ao desenvolvimento de câncer gástrico. OBJETIVO: Neste estudo transversal, esperamos observar a correlação acima mencionada na análise de prontuários de 67 pacientes de ambos os sex

40. Propolis polyphenolic compounds affect the viability and structure of Helicobacter pylori in vitro
ABSTRACT To evaluate the anti-Helicobacter pylori activity of the major polyphenol compounds of propolis and their cellular damage, both as single molecule or in combination. Honey bees propolis were fractionated by using CPC and preparative HPLC. Four major polyphenols (chrysin, pinocembrin, galangin and caffeic acid phenethyl ester) were identified by thin

41. TIME TRENDS OF HELICOBACTER PYLORI PREVALENCE IN ITAJAÍ - SC: A RETROSPECTIVE STUDY OF 25 YEARS BASED ON ENDOSCOPIC DATABASE
RESUMO CONTEXTO: A bactéria Helicobacter pylori associa-se fortemente ao desenvolvimento do adenocarcinoma gástrico. Atualmente, a prevalência em países desenvolvidos é de 40%, porém esse valor cresce consideravelmente em países em desenvolvimento, que chegam a alcançar taxas de até 90%. OBJETIVO: O objetivo desta pesquisa foi determinar a preva

42. The role of high sensitive C-reactive protein and histopathological evaluation in chronic gastritis patients with or without Helicobacter pylori infection
Abstract Purpose: To evaluate serum levels of high-sensitivity C-reactive protein (hs-CRP) in chronic gastritis patients to predict Helicobacter pylori (HP) infection, inflammatory activity, and precancerous lesions. Methods: A total of 811 patients with upper gastrointestinal symptoms and histopathological diagnosis of chronic gastritis were enrolled in

43. [ARTICLE PARTIAL RETRACTION] PREVALENCE OF HELICOBACTER PYLORI INFECTION IN DYSPEPTIC PATIENTS AND ITS ASSOCIATION WITH CLINICAL RISK FACTORS FOR DEVELOPING GASTRIC ADENOCARCINOMA
RESUMO CONTEXTO: No Brasil, particularmente nas áreas mais pobres, a prevalência da infecção por Helicobacter pylori pode variar até 90%. Esses índices aumentam com o envelhecimento da população e são distintos entre as diferentes regiões do país. Podendo manifestar diferentes sintomatologias, essa infecção está diretamente relacionada com o

44. Increased serum gastrin in patients with different clinical forms of Chagas disease coinfected with Helicobacter pylori
ABSTRACT Trypanosoma cruzi and Helicobacter pylori (HP) are pathogens that cause chronic diseases and have been associated with hypergastrinemia. The aim of this study was to evaluate the fasting gastrin levels in patients with different clinical forms of Chagas disease (CD), coinfected or not by HP. The enrolled individuals were outpatients attending at the

RESUMO Objetivo: comparar o polimorfismo dos genes Glutationa S-transferase teta 1 (GSTT1) e Glutationa S-transferase mu 1 (GSTM1) da área do tumor com as margens proximal e distal de espécimes de estômago ressecados de pacientes com câncer gástrico, e investigar a presença do DNA do vírus Epstein-Barr (EBV) e Helicobacter pylori. Métodos: coletamo

46. Primary antibiotic resistance and its relationship with cagA and vacA genes in Helicobacter pylori isolates from Algerian patients
Abstract The epidemiology of Helicobacter pylori resistance to antibiotics is poorly documented in Africa and especially in Algeria. The aim of our study was to determine the antibiotic resistance rates, as well as its possible relationship with VacA and CagA virulence markers of isolates from Algerian patients. One hundred and fifty one H. pylori isolate we

47. The interplay between mutations in cagA, 23S rRNA, gyrA and drug resistance in Helicobacter pylori
ABSTRACT In this study, we evaluated the mutations of Helicobacter pylori associated with resistance to clarithromycin and levofloxacin. Furthermore, based on the proposed interaction between antimicrobial resistance and pathogenicity, we correlated the mutation profiles of the strains with the presence of the pathogenicity gene cagA. We analyzed 80 gastric

48. Performance of the 13C-urea breath test for the diagnosis of H. pylori infection using a substrate synthesized in Brazil: A preliminary study
OBJECTIVE: The 13C-urea breath test is the main non-invasive test for the diagnosis of Helicobacter pylori infection. The availability of this test throughout the country is limited, mainly due to the difficulty in obtaining the labeled isotope from abroad. Recently, researchers from the Nuclear Energy Center in Agriculture at the University of São Paulo (
