RESUMO
To determine the relationship between H. pylori density with severity of chronic inflammatory infiltrate. A cross-sectional study. The study was carried out in the Department of Pathology [Histopathology], Army Medical College, National University of Sciences and Technology [NUST] Islamabad, from Nov 2011 to Nov 2012. Gastric antral biopsies of H. pylori associated chronic gastritis were included in the study. Demographic characteristics and relevant clinical information were collected. First hundred biopsies of H. pylori associated chronic gastritis were assessed for density of H. pylori and chronic inflammatory infiltrate. Histopathological features like lymphoid aggregates, ulcer slough, superficial epithelial damage, dysplasia and nuclear reactive changes were simply assessed in case of their presence or absence. A sigruficant moderate positive correlation was found between grades of H. pylori and chronic inflammatory infiltrate [rs= 0.636]. Insigruficant correlation was found with lymphoid aggregates, superficial epithelial damage, dysplasia and nuclear reactive changes. In conclusion this study corroborated the determination of histopathological parameters and depicted that, the greater the density of H. pylori mfection, the greater the degrees of chronic inflammatory infiltrate
