background helicobacter pylori diagnostic tests can be affected by different interventional factors. we studied the effects of smoking, proton pump inhibitors (ppis) and antibiotic administration on results of the bacterial culture, and its diagnosis tests due to polymerase chain reaction (pcr) and rapid urease test (rut) methods. objectives this study was aimed to investigate the undesirable e...

Gastric cancer incidence and mortality have been decreasing in Japan. These decreases are likely due to a decrease in prevalence of Helicobacter pylori infection. Our aim was to characterize the trends in prevalence of H. pylori infection focused on birth-year. We carried out a cross-sectional study that included 4285 subjects who were born from 1926 to 1989. We defined H. pylori infection by t...

objective: childhood infectious diseases are one of the most known environmental pathogenic causes of childhood asthma. the high prevalence of both helicobacter pylori infection and asthma in our country prompted us to assess anyprobable as- sociation between them in childhood. methods: this cross-sectional study recruited 196 children aged 6 to 12 years old comprising 98 asthmatic (case group)...

BACKGROUND/AIMS We investigated the prevalence and relationship of peptic ulcer disease and Helicobacter pylori infection to liver cirrhosis. METHODS We examined 288 patients with liver cirrhosis, 322 patients with non-ulcer dyspepsia, and 339 patients with peptic ulcer disease. Rapid urease test and Wright-Giemsa staining were used for diagnosis of H. pylori infection. RESULTS The prevalen...

INTRODUCTION This study consisted in the comparison of the prevalence of Helicobacter pylori (H. pylori) present in the stomach and in saliva of a sample of Portuguese adolescents and the assessment of the association between H. pylori infection with socio-demographic variables and prevalence of dental caries. MATERIALS AND METHODS A cross-sectional study was designed including a sample of 44...

Background. There are several diagnostic methods for Helicobacter pylori (H. pylori) infection. A cost-effective analysis is needed to decide on the optimal diagnostic method. The aim of this study was to determine a cost-effective diagnostic method in patients with atrophic gastritis (AG). Methods. A decision-analysis model including seven diagnostic methods was constructed for patients with A...

background: helicobacter pylori (h. pylori) resistance to antibiotics has become a global problem and is an important factor in determining the outcome of treatment of infected patients. the purpose of this study was to determine the h. pylori resistance to clarithromycin, metronidazole, and amoxicillin in gastrointestinal disorders patients. materials and methods: in this study, a total of 260...

BACKGROUND Striking similarities between autoimmune gastritis and Helicobacter Pylori (H. pylori)-associated gastritis have suggested a potential link between these two pathologic conditions in the progression of chronic atrophic gastritis (CAG); however, evidence has remained conflicting. METHODS Serum pepsinogen I and II, and antibodies against H. pylori in general, the cytotoxin-associated...

Helicobater pylori plays an important role in the aetiology and development of peptic ulcer disease. The prevalence of H. pylori infection increases with age, and is influenced by low socioeconomic status and poor hygiene owing to person-to-person transmission of the organism by the oral-faecal route. The aim of this study was to investigate the prevalence of H. pylori infection, detected serol...

BACKGROUND Helicobacter-pylori-related duodenal ulcer (DU) is an important cause of dyspepsia. AIM To determine the relationship between the pattern of H. pylori infection and the epidemiology of duodenal ulcer in a single population. DESIGN Prospective two-part study of (i) patients with DU referred for endoscopy because of dyspepsia, and (ii) the incidence of H. pylori infection in the ge...
