Positive result by serology indicates active Helicobacter pylori infection in patients with atrophic gastritis.

Western blotting of total lysate of Helicobacter pylori in cases of atrophic body gastritis.

BACKGROUND Atrophic body gastritis is considered the first important step in the histogenesis of gastric carcinoma, a multistep process starting from chronic gastritis and progressing through chronic atrophic gastritis, intestinal metaplasia, and dysplasia. Helicobacter pylori is involved in the induction of atrophic body gastritis, but documentation of H. pylori infection is difficult because ...

Application of serology in the diagnosis of Helicobacter pylori infection in patients with atrophic gastritis.

High frequency of helicobacter negative gastritis in patients with Crohn's disease.

The frequency of gastric Crohn's disease has been considered low. This study was undertaken to determine the prevalence of chronic gastritis and Helicobacter pylori infection in patients with Crohn's disease. Oesophagogastroduodenoscopy was performed on 62 consecutive patients suffering from ileocolonic Crohn's disease. Biopsy specimens from the antrum and corpus were processed for both histolo...

ENDOSCOPIC NODULAR GASTRITIS: AN INDICATOR OF HELICOBACTER PYLORI INFECTION IN CHILDREN

Objective: To investigate the importance of endoscopic nodular gastritis associated With Helicobacter pylori infection in children. Methods: In this prospective study, 220 consecutive patients (age range 2 to 15 years, mean age 9. 02 ±3 .3 ), 118 of them males (53. 6%) underwent upper endoscopy during evaluation of chronic abdominal pain. The appearance of nodular gastritis was observed du...

Estimation of prevalence of Helicobacter pylori infection in an asymptomatic elderly population comparing [14C] urea breath test and serology.

A non-invasive serological assay devised in this laboratory had a sensitivity and specificity of 100% as determined by culture and confirmed by histology in a group of 47 patients who had undergone endoscopy. The correlation between serology and the non-invasive [14C] breath test was very good. Only one of 24 culture positive patients was, while all 23 culture negative patients were, breath tes...
