Abstract:
Objective To evaluate the feasibility of combined application of helicobacter pylori stool antigen(HpSA)-and traditional serology in epidemiologic study of helicobacter pylori(Hp) infection in children. Methods Hp serum IgG antibodies were examined among 480 healthy children. Heticobacter pylori stool antigen(HpSA) were measured among children who were seropositive. Hp status was defined as positive when stool antigen test was positive, Hp status was defined as negative when seronegative. A case - control study was conducted to identify risk factors of Hp infection in preschool children. Results Among 480 preschool children, 172 (35 8 %) were sero- positive, 64(13.3 %) with positive result of HpSA test were diagnosed as current Hp infection. Univariate factor analysis demonstrated that Hp infection clustered in families and Hp infection was often acquired in childhood by oral-oral and fecal - oral person to person transmission. Conclusions HpSA and serology screening are two nomnvasive tests, simple not costly, effective and accurate. The combination of these 2 noninvasive methods can be applied in epidemiologic study of Hp infection in childrenJAppl Clin Pediatr,2004,19(11):948-950
