  • Title: Beta 2 glycoprotein-I antigen is increased in primary hyperlipidaemia.
    Author: McNally T, Crook M, Mackie IJ, Isenberg DA, Machin SJ.
    Journal: Br J Haematol; 1994 Oct; 88(2):424-6. PubMed ID: 7803298.
    Abstract:
    In order to determine whether elevated levels of beta 2 glycoprotein-I (beta 2GPI) are associated with increased plasma lipids, we measured plasma beta 2GPI antigen levels in 47 patients with primary hyperlipidaemia (20 severe hypercholesterolaemia, nine severe hypertriglyceridaemia, and 18 mixed hyperlipidaemia) and 34 normal healthy subjects. Mean beta 2GPI levels were significantly increased in each patient group (302.3, 272.9 and 299.1 mg/l, respectively) compared to controls (199.6 mg/l) (P < 0.01). Significant correlations were demonstrated between beta 2GPI levels and triglyceride and total cholesterol levels in the control group (r = 0.387, r = 0.559; P < 0.05), but were not observed in all patient groups. These results indicate that beta 2GPI is increased in hyperlipidaemia and that its distribution between plasma lipid fractions is perturbed. Plasma lipid levels should therefore be considered when interpreting results of beta 2GPI antigen assays.
