| Abstract | BACKGROUND: Several putative virulence factors for Helicobacter pylori have been identified including cagA, vacA, and iceA. The aims of the present study were to study the distribution of cagA, vacA, and iceA genotypes in children with H. pylori gastritis and to examine the association of genotypes with severity of gastritis. METHODS: H. pylori DNA was extracted from antral biopsy specimens from 33 children with H. pylori gastritis. Specific polymerase chain reaction assays were used for three genes: cagA, vacA, and iceA. The features of gastritis were graded in accordance with the updated Sydney System. RESULTS: Of the 33 children, 31 (94%) were cagA positive. Twenty-four (72%) had s1c genotype and nine (27%) had s1a. The m1 genotype was seen in 27 (82%) and m2 was found in five (15%). The iceA1 genotype was detected in 25 (76%). Scores of neutrophil activity, chronic inflammation, and H. pylori density were independent of cagA, vacA and iceA status. CONCLUSION: The cagA-positive vacA s1c/m1 iceA1 genotype was predominant in Korean children with recurrent abdominal pain and H. pylori gastritis. The cagA, vacA and iceA genotype were not associated with the severity of gastritis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
