AIM： To investigate whether anti-H pylori antibodies have cross-reaction with antigens of erythrocyte membrane. METHODS： Blood samples were collected from 14 volunteers （8 positive and 6 negative for Hpylori detected by ^13C-urea breath test） of the general population. Erythrocyte membrane proteins of the subjects were examined by Western blot using anti-H pylori serum. The proteins related to the positive bands were identified by mass spectrum analysis. RESULTS： Anti-Hpylori antibodies had cross-reaction with the proteins of about 50 kDa of erythrocyte membranes in all samples independent of H pylori infection. One protein in the positive band was identified as Chain S, the crystal structure of the cytoplasmic domain of human erythrocyte Band-3 protein. CONCLUSION： Anti-HpyloH antibodies cross-react with some antigens of human erythrocyte membrane, which may provide a clue for the relationship between Hpylori infection and vascular disorders.
