Abstract english

Aims We examined whether antibodies against peptides 45 and 210 of apoB-100 are related to myocardial infarction (MI) and severity of coronary atherosclerosis. Methods and results Three hundred and eighty-seven survivors of a first MI (aged < 60 years) and 387 sex- and age-matched controls were characterized in detail. IgG and IgM autoantibodies against native and malondialdehyde (MDA)-modified peptides 45 and 210 of apoB-100 (amino acids 661-680 and 3136-3155) were quantified in plasma and quantitative coronary angiography was performed in 243 patients. Post-infarction patients had significantly lower IgG against the native peptide 210 (IgG-p210(nat)) and higher IgM against the MDA-modified peptide 210 (IgM-p210(MDA)) compared with controls, whereas no differences were found for other antibodies. Plasma concentrations of IgG-p210(nat), but not IgM-p210(MDA), were independently and inversely related to the degree of coronary atherosclerosis in patients. In multiple logistic regression analysis (including established risk indicators), MI risk was 0.55 (95%CI: 0.37-0.81) for individuals in the IgG-p210(nat) upper quartile compared with the remaining individuals. Conclusion Circulating IgG antibodies against the native peptide 210 of apoB-100 are inversely related to the severity of coronary atherosclerosis and associated with lower risk of MI. Epitope 210 of apoB-100 emerges as a target for immunization against atherosclerosis in humans.
