Determination of anti-elastin peptide antibodies in normal and arteriosclerotic human sera by ELISA.
We adapted a highly sensitive and reproducible ELISA technique for the determination of anti-elastin peptide antibodies of IgG type AEAb-IgG) and IgM type AEAb-IgM) in human sera. The determination was performed in the sera of 265 normal and diseased persons. The pathologies studied included obliterative arteriosclerosis of the legs, ischemic heart disease, stroke, diabetes mellitus, type IIb and IV hyperlipoproteinemia and hypertension. No clearcut correlation could be found between AEAb and age. In contrast, in arteriosclerotic patients and especially in obliterative arteriosclerosis of the legs and ischemic heart disease, the concentration of AEAb-IgG was significantly increased. The AEAb-IgM showed no change in the studied diseases. Both types of AEAb were decreased in type IV hyperlipoproteinemia. Anti-elastin antibodies may be involved in the pathomechanisms of the above diseases and the determination of antibody concentrations may be of some help in obliterative arteriosclerotic diseases.
