To investigate the correlation between CD4+/CD8+ T-cells in gastric mucosa with endoscopic appearance in chronic gastritis with or without H.pylori infection. Prospective, cross sectional study is performed in a chronic dyspepsia population in July-November 2009 at Dr. Sardjito General Hospital Yogyakarta, Indonesia. The update Sydney system was used to analyze the gastroscopy appearance. Biopsy specimens were stained with HE-stain and IHC-stain. Data were analyzed by t-test, Mann-Whitney and Spearman correlation test. Number of 88 consecutive subjects are enrolled the study (50% male; 50% female), age 46±15 years; 25% H.pylori positive. The expression of CD4+ and CD8+ were higher in H.pylori negative subjects, but only the CD4+ was significant (P=0.011). A significant correlation was found between CD4+ and CD8+ in both subjects (r(Hp+)=0.62 and r(Hp-)=0.68; P<0.05). The expression of CD4+ and CD8+ in H.pylori positive showed a significant correlation with gastric lesions (r(CD4+)=-0.60; r(CD8+)=-0.42 ; P<0.05), only erosion showed a significant difference in both subjects. A positive correlation was found between CD4+ and CD8+ infiltration in both subjects with or without H.pylori infection, and a negative correlation was only found between gastric lesion with CD4+ and CD8+ infiltration in H.pylori subject. https://acta.tums.ac.ir/index.php/acta/article/view/5681 https://acta.tums.ac.ir/index.php/acta/article/download/5681/4799
