Interleukin-6 and antiphospholipid antibodies in women with contraceptive-related thromboembolic disease
Abstract
The aim of this study was to explore the possible (joint) contributing role of interleukin-6 (IL-6) and antiphospholipid antibodies to the occurrence of the venous thromboembolism in women using oral contraceptives. Interleukin-6 and antiphospholipid antibodies (anti-beta2-glycoprotein I antibody-immunoglobulin M [IgM], G [IgG], and A [IgA]; anticardiolipin-IgM and IgG; antiphosphatidylserine-IgM and IgG) were measured in 30 women (median age 41, range 28-49 years) in the stable period (on average 3.5 years) after first venous thromboembolism. Sixteen patients used oral contraceptives during the episode of venous thromboembolism (oral contraceptives group), whereas 14 patients did not (non-oral contraceptives group). Thirty-seven age-matched, healthy women served as controls Compared with controls, the oral contraceptives group had elevated IL-6 (median interquartile range 2.3 [1.1-4.3] versus 1.4 [0-2.0] pg/mL, P <.05). The oral contraceptives group had elevated anti-beta2-glycoprotein I antibody-IgM in comparison with both the non-oral contraceptives group (median interquartile range 47.5 [2.0-77.0] versus 29.50 [11.00-45.50] OD(450), P <.06) and controls (47.5 [2.0-77.0] versus 17.5 [3.5-30.0] OD(450), P <.001).

Antiphospholipid Syndrome
Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.
