Background: Acid test meals may improve the accuracy of the C urea breath test (UBT). This has been attributed to changes in gastric emptying rather than to the effects of gastric pH on Helicobacter pylori urease. Aims: To determine whether enhancement of CO2 excretion in the UBT in H pylori infected volunteers by acidification of a test meal is due to a delay in gastric emptying. Methods: Urea...

Fourteen Trichoderma isolates were evaluated for their tolerance to two heavy metals, nickel and cadmium. Three isolates, MT-4, UBT-18, and IBT-I, showed high levels of nickel tolerance, whereas MT-4, UBT-18, and IBT-II showed better tolerance of cadmium than the other isolates. Under nickel stress, biomass production increased up to a Ni concentration of 60ppm in all strains but then decreased...

BACKGROUND There are no data addressing the usefulness of non-invasive tests for the detection of Helicobacter pylori (HP) infection in celiac disease (CD). AIM The aim of this study was to compare two most sensitive and specific tests - urea breath test (UBT) and fecal antigen test (FAT) in HP diagnosis in CD patients. MATERIALS AND METHODS The study comprised of 76 CD patients, 49 healthy...

INTRODUCTION. Helicobacter pylori infection can be diagnosed by biopsy-based or noninvasive methods. Our aim was to identify H pylori-positive patients on hemodialysis by the noninvasive method of H pylori stool antigen (HPSA) and investigate its diagnostic accuracy for assessment of the eradication of infection after treatment in comparison with urea breath test (UBT). MATERIALS AND METHODS. S...

BACKGROUND Chronic idiopathic urticaria (CIU) is one of the most frequent skin diseases, however its causes remain unknown in the vast majority of cases. There is increasing evidence for systemic effects of gastric Helicobacter pylori infection, which may result in extra gastrointestinal disorders. Although CIU can result from several causes, a possible relationship between chronic urticaria an...

BACKGROUND Previous studies have demonstrated a higher prevalence of Helicobacter pylori (H. pylori) infection in patients with Parkinson's disease (PD) compared to controls. H. pylori infection affects levodopa absorption and its eradication significantly improves clinical response to levodopa. Here, we studied the prevalence of H. pylori infection and its eradication effects among our PD pati...
