Abstract:
Objective To probe the relationship between Helicobacter py lori(Hp) IgG antibody components and coronary heart disease(CHD). Meth ods Hp serum specif ic IgG antibodies (Hp-IgG) and antibody components were measured by immunoblot ( IBT) methods in 209 CHD patients and 191 healthy controls from Mar.2001 to Sep 2 003. Results Of the 209 patients with CHD, 152(73%) were serop ositive to Hp comp ared with 113(59%) of the 191 healthy controls(P=0.0042). The Hp antibody co n tained different antibody components, such as cytotoxin-associated gene product A (CagA), vacuolating cytotoxin protein A (VacA), urease A (UreA), urease B (UreB ) etc,and only seropositivity to component UreB66 in CHD group was significantl y higher than that in healthy control (P=0.0001). Multiple Logistic Regression analysis revealed that the Hp antibody component UreB66 was significantly correl ated with CHD (P
