OBJECTIVE: Helicobacter pylori is a bacterial pathogen associated with chronic gastritis, peptic ulcer disease, gastric adenocarcinoma, and gastric mucosa associated lymphoid tissue lymphoma. Current treatment guidelines support a 7- to 14-day, triple-drug protocol consisting of a proton-pump inhibitor (PPI), clarithromycin, and either amoxicillin or an imidazole. The initial eradication rates for this regimen were 80 to 90%. Nevertheless its effectiveness has declined as the antibiotic resistance to clarithromycin and metronidazole has emerged...

AIM: To investigate the bactericidal effects of calcium chelated N-acetylneuraminic acid-glycomacropeptide (CaG-NANA) against Helicobacter pylori (H. pylori). METHODS: For manufacture of CaG-NANA, calcium (Ca) was combined with glycomacropeptide (GMP) by chelating, and N-acetylneuraminic acid (NANA) was produced with Ca-GMP substrate by an enzymatic method. The final concentration of each component was 5% Ca, 7% NANA, 85% GMP, and 3% water. For in vitro study, various concentrations of CaG-NANA were investigated under the minimal inhibitory concentration (MIC)...

Gastric cancers are sometimes diagnosed in patients who have successfully undergone Helicobacter pylori (H. pylori) eradication. We analyzed the clinicopathological features of gastric cancers detected after eradication to clarify their characteristics. We reviewed 31 patients with 34 cases of gastric cancer detected after successful H. pylori eradication. Clinicopathological characteristics analyzed included interval since eradication, interval since last endoscopy, tumor size, and depth of invasion. Patients were classified into two groups: early detection (<1 year since eradication) and delayed detection (≥1 year since eradication)...

Background Helicobacter pylori (H. pylori) infection is the most common chronic bacterial infection worldwide affecting approximately half of the world's population. A number of screening tests as well as complex multi-drug therapies are available for the detection and treatment of H. pylori infection. However, the optimum eradication rates of H. pylori infection can only be achieved if adherence to drug therapy is higher. Therefore, it is of utmost importance to determine the factors leading to poor adherence to obtain successful treatment outcomes...

This article describes the main conclusions drawn from the presentations on Helicobacter pylori infection in Digestive Diseases Week, 2016. Despite the undeniable widespread reduction in the prevalence of this infection, infection rates continue to be high in developing countries. The prevalence of clarithromycin, metronidazole and quinolone resistance is markedly high in most countries and continues to rise. The management of H. pylori infection in patients with peptic ulcers still leaves much to be desired...

We previously reported that activation of the B cell-activating factor (BAFF) pathway upregulates NF-κB and induces BCL3 and BCL10 nuclear translocation in H. pylori (HP)-independent gastric diffuse large B-cell lymphoma (DLBCL) tumours with evidence of mucosa-associated lymphoid tissue (DLBCL [MALT]). However, the significance of BAFF expression in HP-independence of gastric low-grade MALT lymphomas (MALT lymphoma) without t(11;18)(q21;q21) remains unexplored. Sixty-four patients who underwent successful HP eradication for localized HP-positive gastric MALT lymphomas without t(11;18)(q21;q21) were studied...

We previously reported that early-stage gastric diffuse large B-cell lymphomas (DLBCLs), including DLBCLs with (DLBCL[MALT]) and without ('pure' DLBCL) the features of MALT lymphomas, can achieve long-term complete remission after frontline Helicobacter pylori (HP) eradication (HPE). We recently reported that expression of CagA and CagA-signaling molecules (p-SHP2 and p-ERK) is associated with the HP-dependence of gastric MALT lymphoma. However, the significance of CagA and CagA-signaling molecules in gastric DLBCL remains unexplored...

OBJECTIVE: Proton pump inhibitor-based triple therapy with two antibiotics for Helicobacter pylori eradication is widely accepted, but this combination fails in a considerable number of cases. Some studies have shown that cranberry inhibits the adhesion of a wide range of microbial pathogens, including H. pylori. The aim of this study was to assess the effect of cranberry on H. pylori eradication with a standard therapy including lansoprazole, clarithromycin, and amoxicillin (LCA) in patients with peptic ulcer disease (PUD)...

For decades, treatment of infectious diseases has been a strong focus of interest, for both researchers and healthcare providers. Chronic infection with Helicobacter pylori (H. pylori) has been reported to be associated with several diseases, such as ulcer disease, gastric adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. Infection with H. pylori is generally acquired during childhood and can persist indefinitely, if not treated systematically. Unfortunately, although several strategies have shown high efficacy results, treatment of the H...

REVIEW

Gastric polyps become a major clinical problem because of high prevalence and tendency to malignant transformation of some of them. The development of gastric hyperplastic polyps results from excessive proliferation of foveolar cells accompanied by their increased exfoliation, and they are macroscopically indistinguishable from other polyps with lower or higher malignant potential. Panendoscopy allows detection and differentiation of gastric polyps, usually after obtaining histopathological biopsy specimens...

Repeated experimental reinfection of two subjects indicates that Helicobacter pylori infection does not promote an immune response protective against future reinfection. Our results highlight the importance of preventing reinfection after eradication, through public health initiatives, and possibly treatment of family members. They indicate difficulties for vaccine development, especially therapeutic vaccines.

BACKGROUND: Helicobacter pylori (H. pylori) infection is associated with a low platelet count in patients with immune thrombocytopenic purpura (ITP). While eradication of H. pylori is an established therapy for increasing the platelet count in ITP patients, it is unclear whether or not eradication will similarly affect the platelet counts in patients with chronic liver diseases (CLDs). We herein examined the effect of H. pylori eradication on the platelet counts in hepatitis C virus (HCV)-related CLD patients...
