Gastric mixed adenoneuroendocrine carcinoma arising from Helicobacter pylori-associated multifocal atrophic gastritis is exceedingly rare. An added association with autoimmune thyroiditis in this case highlighted a complex interplay between Helicobacter, autoimmunity and gastric atrophy. A 55-year-old hypothyroid female presented with hematemesis and a large polypoidal mass in the gastric fundu...

Endoscopic findings of the background gastric mucosa are important in the Helicobacter pylori-seroprevalent population. It is strongly correlated not only with the risk of gastric cancer, but also with the excretion ability of gastric mucosa cells. In noninfected subjects, common endoscopic findings are regular arrangement of collecting venules, chronic superficial gastritis, and erosive gastri...

Helicobacter pylori (HP) chronic gastritis can lead to precursor stages of gastric cancer. New biological markers have been proposed to study the gastric mucosal state. We evaluate biological results in comparison with histological ones in a dyspeptic population. Forty nine dyspeptic patients underwent endoscopy with gastric biopsies for histological examination. Blood samples were obtained to ...

BACKGROUND Obesity increases the risk for malignancies in various tissues including the stomach. Atrophic gastritis with precancerous lesions is an obesity-associated disease; however, the mechanisms that underlie the development of obesity-associated atrophic gastritis are unknown. Leptin is a hormone derived from stomach as well as adipose tissue and gastric leptin is involved in the developm...

Background: G.lamblia is a common worldwide parasitic infection which colonizes the upper part of small intestine causing giardiasis. Aim of the Work: This study aims to detect gastric giardiasis in children receiving antacid drugs and undergoing upper endoscopy at El Mounira Children Hospital, Cairo University. In addition to study the effect of H.pylori on colonization of gastric mucosa by G....

The fact that long-term use of proton pump inhibitors (PPIs) aggravates corpus atrophic gastritis in patients with Helicobacter pylori infection has been proven clinically and experimentally. Corpus atrophic gastritis is a known risk factor for gastric cancer. Therefore, gastric neoplasia might be associated with the long-term use of PPIs. One of the causes of worsening corpus atrophic gastriti...
