Materials and Methods: This cross – sectional and case – control study was done in Qaem medical hospital, Mashhad during the years 1384 and 1385, for serum level detection of anti – H.pylori IgG and IgA antibodies in blood samples of both control and case groups. The variables were age, sex and serum test results. Results: 45 patients (39 male and 6 female) and 42 controls (33 male and 9 female) were evaluated. 2 groups were matched for age and sex. Positive IgG and IgA results in patients in order was 3 person (6.6 percent) and 3 person (6.6 person) and in control group 26 person (61.9%) and 12 person (28.5%). Result (P>0.001) was for healthy group showing the protective effect of H.
