An association between Helicobacter infection and autoimmune hepatitis (AIH) in children was investigated. The prevalence of antibodies to H. pylori did not differ between the AIH and the control group, (22% versus 14%), and antibodies to non-gastric Helicobacter were not detected in either group. H. pylori DNA was found in two AIH liver tissues, but Helicobacter was not cultured from any sample.

The gastric pathogen Helicobacter pylori utilize glucose during metabolism, but the underlying mechanisms linking to oxygen-18 ((18)O) and carbon-13 ((13)C)-isotopic fractionations of breath CO2 during glucose metabolism are poorly understood. Using the excretion dynamics of (18)O/(16)O and (13)C/(12)C-isotope ratios of breath CO2, we found that individuals with Helicobacter pylori infections e...

OBJECTIVE To determine the prevalence of Helicobacter pylori in symptomatic outpatients in Red Rebagliati (EsSalud) from 2010 to 2013. MATERIAL AND METHODS An observational, transversal and analytical study. Records of outpatients with diagnostic 13C-urea breath test of Helicobacter pylori in the period 2010-2013 were reviewed. RESULTS Of the 1711 patients, the overall prevalence of Helicob...

BACKGROUND AND AIM Identifying specific gastric mucosal morphologic patterns useful for detecting Helicobacter pylori associated gastritis and correlation with histopathological severity. METHODS The endoscopists classified the C-NBI gastroscopic findings into 5 gastric mucosal morphologic patterns as follows: type 1: regular arrangement of collecting venules, type 2: cone-shaped gastric pits...

The polymerase chain reaction was used to develop a method for the detection of Helicobacter pylori, a causative agent of gastritis, as well as for the elucidation of its mode of transmission. A genomic library of Helicobacter pylori DNA in Escherichia coli JM109 was constructed by cloning Hind III-digested DNA fragments into plasmid vector pUC18. The nucleotide sequences from seven recombinant...

To determine the frequency of Helicobacter pylori infection in patients with lichen planus presented to tertiary care hospital Hyderabad. Patiehts and Methods This cross sectional descriptive study of six months was carried at Liaquat University Hospital Hyderabad Sindh, Pakistan from February 2008 to July 2008. All patients above 12 years of age, of either gender, were known / already diagnose...

The role of Helicobacter pylori infection in the symptom complex associated with non-ulcer dyspepsia is uncertain, despite the presence of the organism in a high proportion of these patients. In order to exclude physician bias in history taking, 18 patients (9 female) diagnosed as non-ulcer dyspepsia, after endoscopy and gallbladder ultrasonography, underwent computer interrogation using the Gl...

BACKGROUND Osteoporosis affects approximately 30% of postmenopausal women. Gastrectomy, pernicious anemia, and more recently Helicobacter pylori infection, have all been implicated in the pathogenesis of osteoporosis. A reduced parietal cell mass is a common feature in these conditions. AIM To study a possible relationship between chronic gastritis, parietal cell density of the oxyntic mucosa...

Objetivo: determinar la prevalencia de la infección por Helicobacter pylori en pacientes gastrectomizados por enfermedad no neoplásica, y que han desarrollado posteriormente cáncer gástrico. Material y métodos: estudio retrospectivo con reclutamiento de todos los pacientes con gastrectomía parcial por enfermedad péptica benigna que han sido sometidos a una exploración endoscópica entre 1995-200...

BACKGROUND Helicobacter species associated with human infection include Helicobacter pylori, Helicobacter heilmannii and Helicobacter felis among others. In this study we determined the prevalence of H. pylori and non-Helicobacter pylori organisms H. felis and H. heilmannii and analyzed the association between coinfection with these organisms and gastric pathology in patients presenting with dy...
