We studied sera from patients with various disorders including collagen diseases, Buerger's disease, deep vein thrombosis, repeated abortions and idiopathic thrombocytopenic purpura in order to measure anticardiolipin antibody (aCL) titers. In our assay system, we can detect aCL against bovine cardiolipin and the complex of cardiolipin and beta 2-glycoprotein I (beta 2-GPI). This was done with simultaneous assays using blank wells and bovine cardiolipin coated wells in the EIA method in which both wells were also coated with bovine serum albumin possibly containing beta 2-GPI, then aCL titers was given by subtraction of O.D. values of blank wells from those of cardiolipin coated wells. When the aCL was quantified by anti human immunoglobulin antibodies, collagen diseases showed positive aCL in 15 (11.5%) out of 130 sera with positive anti ENA antibodies, 3 (11.1%) out of 27 sera with positive anti DNA antibodies and 3 (5.2%) out of 58 sera with other positive ANA sera. The other hand, we found positive aCL in 2 (4.9%) out of 41 sera from patients with Buerger's disease, 4 (36.4%) out of 11 sera from patients with deep vein thrombosis, 1 (7.7%) out of 13 sera from patients with repeated abortions and 6 (14.6%) out of 41 sera from patients with idiopathic thrombocytopenic purpura. Twenty one (61.8%) out of these aCL positive sera had also positive IgG-aCL for the assay using anti human IgG antibody. Compared to previous reports, we thought, low incidence of aCL in our study was due to exclusion of anti beta 2-GPI antibody in our assay system.
