Reactivity with oxidised cardiolipin or with antigens derived from the reaction of proteins with lipid peroxidation products of sera from patients with alcoholic liver disease positive (β₂-GP1⁺; n=23) or negative (β₂-GP1 ; n=13) for the presence of antibodies against β₂-glycoprotein 1. ELISA plates coated with oxidation protected (CL) or oxidised (Ox-CL) cardiolipin, or with malondialdehyde (HSA-MDA) or products from arachidonic acid peroxidation (HSA-APP) were used to evaluate IgG binding. Results are mean (SD) ELISA values. **p<0.005, ***p<0.001 versus β₂-GP1 negative subjects; †††p<0.001 versus native cardiolipin.
