Lupus anticoagulant (LA) and anticardiolipin antibodies (ACA) have been associated with thrombotic events and recurrent fetal loss. In order to assess the role of LA with the thrombotic tendency in various disease states we evaluated 38 patients with confirmed LA [tissue thromboplastin index (TTI) greater than 1.3; circulating anticoagulant index (CAI) greater than 15], subgrouped as follows: a) LA associated with systemic lupus erythematosus (SLE) (n = 13); b) primary antiphospholipid syndrome (PAPS) (n = 16); and c) LA associated with other disorders (n = 9). Male/female ratio differed between the groups: 0/13, 6/10 and 4/5, respectively. Venous and arterial thrombotic events were more common in the PAPS group (87%) compared with the SLE group (61%) and the other disorders group (22%). Serum ACA antiphospholipid IgG levels by ELISA were increased in the SLE and PAPS patients, but did not differ between the groups (167 +/- 24 vs. 190 +/- 28 mu respectively). Antiphospholipid IgM levels were higher in the SLE group compared with the PAPS group (127 +/- 15 vs. 67 +/- 16 mu). Mean TTI and CAI levels did not differ between the SLE, PAPS and other disorders groups (1.8 +/- 0.19, 2.8 +/- 0.9, 2.0 +/- 0.3 for TTI; 25 +/- 4, 33 +/- 4, 32 +/- 5 for CAI). Likewise TTI, CAI and ACA levels did not differ in patients with or without thrombosis. We conclude that the prevalence of thrombotic manifestations varies among patients with similar serum intensities of LA and levels of ACA, suggesting that other factors may be involved in the pathogenesis of thrombosis in these patients.

UI	MeSH Term	Description	Entries
D008180	Lupus Erythematosus, Systemic	A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.

D011248	Pregnancy Complications	Conditions or pathological processes associated with pregnancy. They can occur during or after pregnancy, and range from minor discomforts to serious diseases that require medical interventions.

D011250	Pregnancy Complications, Hematologic	The co-occurrence of pregnancy and a blood disease (HEMATOLOGIC DISEASES) which involves BLOOD CELLS or COAGULATION FACTORS. The hematologic disease may precede or follow FERTILIZATION and it may or may not have a deleterious effect on the pregnant woman or FETUS.
