title: Helicobacter pylori-associated gastritis in Kuwait: endoscopy-based study in symptomatic and asymptomatic children.
abstract: Information is limited concerning the prevalence of Helicobacter pylori infection in asymptomatic children. Since January 1989, we have endoscoped 60 children for recurrent abdominal pain or for obtaining small-intestinal biopsy (their ages were a mean of 6.6 (range 9 months-13 years); there were 37 boys and 23 girls. Antral biopsies were obtained from all subjects and these were studied for the presence of gastritis and stained for H. pylori using modified Gram's stain. All biopsies were cultured for H. pylori. Children endoscoped for small-intestinal biopsy (n = 18) were used for comparison. Of the 42 children who had abdominal pain, 24 showed histological gastritis and 13 had H. pylori on microscopy (31% H. pylori-associated gastritis). In the compared group, five showed histological gastritis, and all had H. pylori on microscopy (27.7%). Culture was positive in 15; sensitivity was 85.7%. Six children, three pairs of siblings, had H. pylori gastritis supporting environmental etiology. Two had coinfection with intestinal giardiasis. Seven children were treated with daily oral amoxycillin (50 mg/kg) and tinidazole (20 mg/kg) for 6 weeks. In 3 (42.3%) H. pylori colonization cleared with healing of gastritis and resolution of symptoms. These results indicate that H. pylori gastritis is equally prevalent in symptomatic and asymptomatic children (31 and 27.7%, respectively; p > 0.05) in our population. It seems that the combination of oral amoxycillin and tinidazole is a poor choice in the treatment of H. pylori-associated gastritis in Kuwaiti children.
