The primary mode of transmission of Helicobacter pylori, a human pathogen carried by more than half the population worldwide, is still unresolved. Some epidemiological data suggest water as a possible transmission route. H. pylori in the environment transforms into a nonculturable, coccoid form, which frequently results in the failure to detect this bacterium in environmental samples by convent...

Background: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune demyelinating disease in the central nervous system. Association between NMOSD and Helicobacter pylori (H. pylori) infection has been investigated, but few studies have assessed the relationship between H. pylori and seronegative AQP4-Ab NMOSD. Objectives: This study aimed to survey the association between H. pylori...

Objective: In our study, we aimed to evaluate the prevalence of Helicobacter pylori (H. Pylori) and characteristics antrum pathologies in patients with portal hypertensive gastropathy. Materials Methods: Antrum presence H. Pylori evaluated Giemsa stain gastroscopies 203 Results: A total patients, 119 male, 84 female, gastropathy was included study. hypertension, rate positivity 15.3%. This dete...

Background: The idiopathic peptic ulcers (IPU), or non-Helicobacter pylori nonsteroidal anti-inflammatory drugs (NSAIDs)-associated ulcers, are a serious therapeutic challenge. prevalence of IPU is increasing in some parts the world. Objectives: This study aimed to determine southeastern Iran. Methods: In this cross-sectional study, total 367 patients with active ulcer were diagnosed by endosco...

ATPase activity in permeabilized cells of Helicobacter pylori as well as those of Helicobacter felis and Campylobacter jejuni was analyzed. The ATPase activities in these cells were most susceptible to sodium azide, fluoroaluminate, and dicyclohexylcarbodiimide, which are typical inhibitors of F ATPases. Optimal values for maximal activity were found to be at approximately pH 6.4, 6.0, and 6.0 ...

Helicobacter pylori is an important risk factor for peptic ulcers. If infection withH pylori is cured, ulcers associated with H pylori do not recur. An H pylori “test and treat” strategy for patients with peptic ulcers having long term antisecretory treatment has been suggested, in the hope that eradicating H pylori would curtail the rising use of antiulcer drugs. 2 We describe the long term ef...

OBJECTIVE To establish the prevalence of Helicobacter pylori colonization of dental plaque and its correlation with Helicobacter pylori infection of the antral mucosa in patients with symptomatic dyspepsia. METHODS Seventy eight adult dyspeptic patients undergoing upper gastrointestinal tract endoscopy were prospectively enrolled. Four air dried dental plaque cytology slides and four gastric ...

Helicobacter pylori is the causative agent of gastritis and peptic ulcer disease. Eradication of H. pylori is hard to achieve and often require multiple antibiotics regimens. These regimens are quite expensive and have substantial side effects. Licorice is a traditional drug which is frequently used for gastric discomforts in Iran. The susceptibility of H. pylori to the extract of licorice has ...

BACKGROUND The urea blood test (Ez-HBT) has been shown to compare favourably with the urea breath test in the diagnosis of active Helicobacter pylori infection. AIM To examine the performance characteristics of the Ez-HBT Helicobacter blood test in establishing success or failure of therapy in H. pylori-infected adults using the 13C urea breath test as the reference method. METHODS 13C urea...
