Abstract:
Introduction Ulcer disease occurrence is increased among patients with liver cirrhosis. It is widely accepted that Helicobacter pylori infection is important in etiology of ulcer disease. The role of Helicobacter pylori infection in pathogenesis of ulcer disease in patients with liver cirrhosis has not been satisfactorily explored yet. Objective The aim of this study was to determine frequencies of Helicobacter pylori infection in patients with liver cirrhosis in relation to the etiology of cirrhosis, clinical stage and concomitant ulcer disease. Method We studied 50 patients with liver cirrho

Abstract:
The order Campylobacterales comprises two genera: Campylobacter and Helicobacter, with a widespread distribution in both humans and animals. They are Gram-negative, spiral, helical and microaerophilic bacteria, with an optimal growth temperature of 37?C for H. pylori and 42?C for C. jejuni strains. While Helicobacter pylori are restricted to humans, other helicobacter species can be found in different mammals and occasionally in humans. Several Campylobacter species are recognized as human pathogens, while distinct species are pathogenic only occasionally, in children, the elderly and immunoco

Abstract:
The discovery that Helicobacter pylori infection is the major cause of peptic ulcer disease revolutionised our views on the etiology and treatment of the disease. This discovery has tempted many experts to conclude that psychological factors and, specifically, stress are unimportant. However, Helicobacter pylori infection alone does not explain fully the incidence and prevalence of peptic ulcer disease. It has been demonstrated that stress can cause peptic ulcer disease even in the absence of Helicobacter pylori infection, supporting a multicausal model of peptic ulcer etiology. Psychological

Abstract:
SummaryRecurrent abdominal pain is one of the most common presentations to pediatricians; yet an organic etiology can be found in only 10% of cases. Because infection with Helicobacter pylori in adults and children results in gastritis, a causative role for the organism has been postulated. To investigate this theory, we conducted a prospective case‐control study in children with recurrent abdominal pain using serum H. pylori IgG antibodies measured by an enzyme immunoabsorbent assay. Age, sex, ethnicity, and socioeconomic status were adjusted in the statistical model. Five subjects (5.1%) and
