Abstract
- The aim of this study was to investigate the Lewis antigen expression in Helicobacter pylori gastric MALT lymphoma associated strains in comparison to chronic gastritis only strains. Forty MALT strains (19 cagPAI (-) and 21 cagPAI (+)) and 39 cagPAI frequency-matched gastritis strains (17 cagPAI (-) and 22 cagPAI (+)) were included in this study. The lipopolyssacharide for each strain was extracted using a hot phenol method and the expression of Le(x) and Le(y) were investigated using Western Blot. The data were analyzed according to the strains' cagPAI status and vacA genotype. Le(x) was identified in 21 (52.5%) MALT strains and 29 (74.3%) gastritis strains. Le(y) was identified in 30 (75%) MALT strains and 31 (79.5%) gastritis strains. There was an association between cagPAI positivity and Le(x) expression among MALT strains (p
