Abstract:
BACKGROUND/AIMS:Studies on re-infection of Helicobacter pylori are limited. This study was designed to determine if there are clinical features of H. pylori re- infection related to gastroduodenal diseases or histological findings. METHODS: From a population of patients that were treated for H. pylori eradication from May 2003 to September 2007, 129 subjects were enrolled. Regimens were PPI-based triple or quadruple agents and follow-up methods were UBT, CLO or histology. RESULTS: A total of 29 subjects experienced a recurrence (within one year, 17 subjects; between one and two years, eight subjects; more than two years, four subjects). Recurrence periods were 2 to 32 months, and the mean period was 12.62+/-8.40 months. Among 29 subjects, eight subjects had chronic atrophic gastritis, 14 subjects had a peptic ulcer, five subjects had stomach cancer and two subjects had a MALT lymphoma; there were no statistical differences of the odds ratio between matched diseases. By use of the Updated Sydney System, neither H. pylori colonization density nor neutrophil infiltration nor monocyte infiltration grade in histology was associated with recurrence or re-infection. CONCLUSIONS: Neither histological findings nor gastroduodenal diseases was associated with H. pylori re-infection. The re-infection rate in this study was approximately 6.2%. This rate was slightly higher than rates reported in other recent studies in Korea.
