Plasma samples from nineteen patients with well characterized lupus anticoagulants (LA) were evaluated using a series of test systems. An ELISA was used to determine if the plasmas contained antiphospholipid antibodies (APA); fifteen of nineteen LA plasmas contained APA, with five exhibiting IgG only, two exhibiting IgM, and eight plasmas containing both IgG and IgM. Anti-phosphatidyl serine (PS) was the predominant IgG specificity and all IgM APA-containing plasmas reacted with phosphatidyl inositol (PI). An ELISA was developed to determine if LA plasmas contained immunoglobulin which would associate with cultured human umbilical cord vein-derived endothelial cells (HUV); ten of nineteen plasmas contained endothelium associated immunoglobulin (EAI). There was significant concordance between the occurrence of EAI and IgM anti-PI. The occurrence of EAI or APA, either singly or in combination, did not correlate with a past history of thrombosis. Patient plasmas were incubated with HUV and examined for effects on HUV prostacyclin (PGI2) secretion; six plasmas significantly stimulated PGI2 secretion and one plasma was inhibitory. Finally, plasma levels of free and total antigenic protein S were determined by EID. Five plasmas contained significantly reduced levels of free antigenic protein S, and total antigenic protein S was reduced in ten plasmas. Patient histories were examined for evidence of thrombotic episodes; six patients had a history of either arterial or venous thrombosis, with five of these six patients having drug-induced LA. Thus, unlike previous studies, drug-induced LA were associated with thrombosis.
