Chronic gastritis and helicobacterpylori: a histopathological study of gastric mucosal biopsies

ABSTRACT

The aim of this study was to observe the histological features of chronic gastritis and associated effects due to Helicobacter pylori infection in 176 randomly selected antral biopsy specimens of chronic gastritis cases. The specimens were reviewed for the presence or absence of H.pylori. The activity [neutrophilic infiltration] of gastritis and the presence or absence of mucosa-associated lymphoid tissue [MALT] were also noted. Chi-square test [Pearson value] was used to analyze categorical variables. H.pylori was detected in 110 [62.5%] cases of chronic gastritis. There was a significant association between H.pylori infection and activity of chronic gastritis [p=0.002]. Lymphoid aggregates were significantly more frequently noted in H pylori-positive patients [68.2%] vs. H.pylori negative group [47%], [p=0.005]. It is concluded that H.pylori is significantly associated with active chronic gastritis and with formation of mucosa-associated lymphoid tissue [MALT], which may develop into gastric lymphoma [MALT type]
