Systemic Lupus Erythematosus (SLE) is a chronic autoimmune condition characterized by multi-organ system inflammation with the generation of autoantibodies. The specific cause of SLE is unknown but multiple factors seem to be associated with the development of the disease including: genetic, epigenetic, ethnic, hormonal, and environmental factors.

Very rarely do SLE and TTP present simultaneously. Both disease processes have overlapping clinical features which makes diagnosis and management challenging.

Multiple physiologic changes in pregnancy contribute to the increased risk of VTE. VTE in this setting presents unique challenges for diagnosis and management.

Anticoagulation primarily relies on low molecular weight heparin, but unfractionated heparin and fondaparinux may also be used when needed. Warfarin is a known teratogen and induces an anticoagulant effect in the fetus. Safety data for other anticoagulants is lacking. Thrombolysis should be limited to patients with significant hemodynamic compromise due to the high risk of bleeding with this intervention. For individuals with prior VTE who are no longer on anticoagulation, prophylactic anticoagulation is usually reserved for those with prior estrogen-associated or unprovoked VTE. Future prophylaxis can be limited to additional pregnancies in most individuals. Future exposure to exogenous estrogen should be avoided. Prophylactic anticoagulation on the basis of heritable thrombophilias without a personal history of VTEs is not usually indicated, as risks of bleeding and interference with the use of neuraxial anesthesia outweigh benefits in most instances.
