Neurological and Neuropsychiatric Manifestations of Antiphospholipid-Antibody Syndrome (APS)

Antiphospholipid Syndrome Secondary to Lupus Anticoagulant: Case Report for Clinical Anticoagulation Determination

Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by venous or arterial thrombosis and/or pregnancy morbidity in the presence of persistent laboratory evidence of antiphospholipid antibodies (APL). APS can occur as a primary condition but can also occur in the presence of systemic lupus erythematosus (SLE) or other systemic autoimmune diseases such as rheumatoid arthritis (RA) or Sjogren’s Syndrome. Our case focuses on a 21-year-old female with a history of "going numb and having no ability to speak" with a total of approximately 20 such episodes, with no known triggers for these episodes. A hypercoagulable profile was performed and indicated an elevation in lupus anticoagulant (LA), which was also positive at repeat testing after 12 weeks, meeting the criteria for APS. Oral contraceptive pills (OCP) were stopped immediately, and she was started on daily aspirin. When hematology was consulted and evaluated, the patient reported a history of possible transient ischemic attacks (TIA); however, there was no history of deep vein thrombosis (DVT), pulmonary embolism (PE), or miscarriages. Recommendations from hematology were to continue the daily aspirin but did not recommend the addition of anticoagulation therapy. Additional recommendations included avoiding risk factors for thrombosis such as the use of birth control pills, smoking, and a sedentary lifestyle or obesity. Given the young age of our patient, as well as multiple TIA associated with APS secondary to LA, the patient was started on anticoagulation contrary to hematology’s recommendations.
