Helicobacter pylori infection in Thai children with recurrent abdominal pain.

Sixty-five children with recurrent abdominal pain underwent gastrointestional endoscopy which showed Hp gastritis without duodenal ulcer in 16.9 per cent of cases. The prevalences of infection in recurrent abdominal pain and asymptomatic children were not different.

Helicobacter pylori and peptic ulcer diseases: prevalence and association with antral gastritis in 210 patients.

Evidence is accumulating that Helicobacter pylori infection plays a major contributory role in peptic ulcer disease [Duodenal Ulcer (DU) and Gastric ulcer (GU)] and non-ulcer dyspepsia (NUD). We, therefore, studied prospectively 210 consecutive patients with upper gastrointestinal symptoms (62 DU, 38 GU and 110 NUD) to determine the prevalence of H. pylori infection and to investigate their association with histological gastritis.
