Abstract Objectives.—To describe the endoscopic biopsy pathology of Helicobacter pylori gastritis, compare bacterial detection by immunohistochemistry using a specific antibody with the Genta stain, and to compare the relative costs of the 2 techniques. Design.—One hundred cases of gastritis identified as positive for H pylori by Genta stain and 100 cases considered negative by the same technique were stained using an anti-H pylori–specific polyclonal antibody. Laboratory reagent and labor costs for the 2 methods were compared. Results.—Chronic active gastritis with lymphoid follicles was significantly associated with H pylori infection (P < .0001). The immunohistochemical method had a sensitivity of 97% and a specificity of 98% compared with the Genta stain, with strong agreement for grading density of organisms (κ = 0.85; P < .001). Reagent costs were similar for both methods, but immunohistochemistry using an autoimmunostainer required less dedicated technical time and hence was less expensive than the Genta stain. Conclusions.—Immunohistochemistry using a specific antibody is an accurate and cost-effective method for H pylori detection in gastric biopsies.
