The hygiene hypothesis links environmental and microbial exposures in early life to the prevalence of atopy, allergy, and asthma. Helicobacter pylori infection is typically acquired in childhood and acquisition of the infection is associated with poor household hygiene. Some population surveys have shown an inverse association between H. pylori infection and atopy, allergy, and asthma leading to the suggestion that H. pylori infection may be protective against disease; others consider it simply a biomarker for poor household hygiene...

BACKGROUND: Atrial fibrillation (AF) increases the risk of thromboembolic stroke. An oral anticoagulant should be administrated to prevent stroke in patients with moderate stroke risk (ie, CHA2DS2-VASc score>2). If the stroke risk is low (i.e. the score=1), however, antiplatelet agent such as aspirin is widely used. Aspirin can cause peptic ulcer disease (PUD) while its alternative, clopidogrel, theoretically does not. OBJECTIVE: To elucidate the efficacy and safety between aspirin and clopidogrel, a multicenter randomized controlled trial was designed in AF patients with low stroke risk...

Currently, surgery is less needed for the treatment of refractory peptic ulcer disease (PUD) or its complications. So, the complications of PUD surgery have been clearly declined. Here in, we present a 42-year-old man with chronic watery diarrhea and significant weight loss during 2 years after gastrojejunostomy for the treatment of obstructive PUD. Small bowel gastrointestinal series showed rapid transit without passage of contrast in the parts of small bowel. The patient was scheduled for exploratory laparotomy...

Helicobacter pylori infection is associated with chronic gastritis, peptic ulcer disease, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma. However, some rare gastric lesions exhibiting distinctive histological features may also be associated with H. pylori infection, including lymphocytic gastritis, granulomatous gastritis, Russell body gastritis, or crystal-storing histiocytosis. Although diverse factors can contribute to their development, there is convincing evidence that H. pylori infection may play a pathogenic role...

Perforated gastric ulcer is one of the most life-threatening complications of peptic ulcer disease with high morbidity and mortality rates. The surgical strategy for gastric perforation in contrast with duodenal perforations often requires consilium and intraoperative debates. The subject of the debate is a 59-year-old male patient who presented with perforated giant gastric ulcer complicated by generalized peritonitis and severe sepsis. The debate is based on a systematized table dividing all factors into three groups and putting them on surgical scales...

Helicobacter pylori infect millions of people around the world. It occupies a niche in the human gastrointestinal tract characterized by high expression of a repertoire of carbohydrates. ABO and Lewis histo-blood group systems are controlled by genes coding for functional glycosyltransferases which synthesize great diversity of related fucosylated carbohydrate in different tissues, including gastrointestinal mucosa, and exocrine secretions. The structural diversity of histo-blood group carbohydrates is highly complex and depends on epistatic interactions among gene-encoding glycosyltransferases...

We studied 135 people (24 people, apparently healthy, 39 uncomplicated peptic ulcer disease, 42 people with complex forms peptic ulcer, 30 and after the treatment of complicated forms of peptic ulcer disease, both sexes (18-45 y.). In all patients, the diagnosis was confirmed fibrogastroduodenoscopy (EGD). Determination of histones and acid soluble fraction (ASF), RNA, DNA, in blood was performed by the method of L. Markusheva. Studies have led to the conclusion that the change in the blood concentration of extracellular nucleic acids in patients with uncomplicated disease and complex shapes can be caused by oxidative stress products and can be a signal for elimination of nucleic acids from cells...

BACKGROUND: Helicobacter pylori (HP) infection is associated with reduced lung function and systemic inflammation in chronic obstructive pulmonary disease (COPD) patients. Azithromycin (AZ) is active against HP and reduces the risk of COPD exacerbation. We determined whether HP infection status modifies the effects of AZ in COPD patients. METHODS: Plasma samples from 1018 subjects with COPD who participated in the Macrolide Azithromycin (MACRO) in COPD Study were used to determine the HP infection status at baseline and 12 months of follow-up using a serologic assay...

BACKGROUND: Around 70-90% of peptic ulcer disease (PUD) is due to Helicobacter pylori and requires treatment with antimicrobials to which these bacteria are susceptible. Common H. pylori diagnostic tests do not provide drug susceptibility data. Using the GenoType HelicoDR PCR test designed for gastric biopsies for simultaneous detection of H. pylori and its resistance to clarithromycin (CLA)/fluoroquinolones (FLQ), we present evidence for stool as an optional test specimen and also provide data on prevalence of H...

Background: Helicobacter pylori (H. pylori) infection is related to peptic ulcer diseases and gastric cancer and eradication of H. pylori should be expected to decrease the risk of their development. Factors affecting H. pylori eradication are antibiotic resistance, CYP2C19 genotypes, drug regimen and patient compliance. Increment of omeprazole and amoxicillin dosage in clarithromycin-containing triple therapy regimen may overcome these problems and may be a better choice than the conventional clarithromycin-containing triple therapy regimen...

Helicobacter pylori (H. pylori) which colonizes the stomach can cause a wide array of gastric disorders, including chronic gastritis, peptic ulcer, and gastric cancer. Recently, accumulating evidence has implicated H. pylori infection in extragastrointestinal diseases such as cardiovascular diseases, neurological disorders, and metabolic diseases. At the same time, many scholars have noted the relationship between H. pylori infection and non-alcoholic fatty liver disease (NAFLD). Despite the positive association between H...

Helicobacter pylori (H. pylori) is an infection that has a role in causing dyspepsia and complications such as peptic ulcer disease and gastric malignancies. In the primary care setting, one can adopt a stepwise approach with the 'test-and-treat' strategy to manage H. pylori-associated dyspepsia in young patients without alarm symptoms. Empiric first-line therapies should be for a two-week duration; options include clarithromycin-containing triple therapy alone or with the addition of bismuth, concomitant therapy and bismuth quadruple therapy...

Helicobacter pylori infection can lead to gastritis, peptic ulcer, and the development of mucosa associated lymphoid tissue (MALT) lymphoma. Treatment and eradication of H. pylori infection can prevent relapse and accelerate the healing of gastric and duodenal ulcers as well as regression of malignancy. Due to the increasing emergence of antibiotic resistance among clinical isolates of H. pylori, alternative approaches using newly discovered antimicrobial agents in combination with the standard antibiotic regimens for the treatment of H...

Helicobacter pylori (H. pylori) is a Gram-negative and motile bacterium that colonizes the hostile microniche of the human stomach, then persists for the host's entire life, if not effectively treated. Clinically, H. pylori plays a causative role in the development of a wide spectrum of diseases including chronic active gastritis, peptic ulceration, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue lymphoma. Due to the global distribution of H. pylori, it is no exaggeration to conclude that smart strategies are contributing to adaptation of the bacterium to its permanent host...
