    Abstract:
    To evaluate various diagnostic tests for Helicobacter pylori (Hp) in children, and to study the spectrum of endoscopic and histological changes in the stomach and duodenum of children with gastroduodenal disorders, associated with Hp infection Children below 12 years of age with various gastroduodenal disorders requiring upper gastrointestinal endoscopy were studied. Endoscopic biopsy specimens were collected from duodenum and antrum. Apart from histopathological examination of biopsy material, rapid urease test (RUT) of the antral biopsy specimen and blood examination to estimate specific IgG antibodies to Hp by Indirect Solid Phase Enzyme Immunoassay was performed. Forty seven children were included. Nine (19.1%) of them were positive both by serology and RUT. Seven (14.9%) were positive by histology. A significant correlation of Hp was noticed with chronic antral gastritis (p = 0.002) and chronic duodenitis (p = 0.006). Age equal to or more than 10 years was found to be significant risk factor for acquiring Hp infection. Prevalence of Hp in children with gastroduodenal complaints was found to be 19%. Both RUT and serology were found to be reliable diagnostic tests for Hp as compared with histology. Antral gastritis and chronic duodenitis had a significant correlation with Hp colonization.
