Recent research indicates that immunological mechanisms may be important for understanding the pathophysiology of HP infection. Differences in the individual cellular immune response may reflect the clinical diversity. The aim of the present study was to investigate the cellular immune response against HP in three clinically well\u2010defined patient groups: HP\u2010positive peptic ulcer, HP\u2010positive and HP\u2010negative gastritis. Biopsies from gastric mucosa were processed for analysis by flow cytometry and histology. The number of T lymphocytes (CD3\n                    <jats:sup>+<\/jats:sup>\n                    ) was significantly higher in HP\u2010positive peptic ulcer (13.8%) than in HP\u2010positive nonulcer gastritis (6.3%). A nonsignificant increase for B lymphocytes (CD19\n                    <jats:sup>+<\/jats:sup>\n                    ) was noted as well. Furthermore, a significant difference was seen in mucosal CD4\/CD8 ratio between HP ulcer (2.4) and nonulcer HP gastritis (1.0) patients. Thus, B cells (CD19\n                    <jats:sup>+<\/jats:sup>\n                    ) and T\u2010helper cells (CD4\n                    <jats:sup>+<\/jats:sup>\n                    ) were dominant in gastric mucosa from peptic ulcer patients, and cytotoxic T cells (CD8\n                    <jats:sup>+<\/jats:sup>\n                    ) were relatively dominant in gastric mucosa from nonulcer patients. In conclusion, distinct differences in the T\u2010cell subset distribution of mucosal lymphocytes were detected in patients with HP infection, strongly correlated with the presence or absence of peptic ulcer.\n
