  • Title: Lupus anticoagulant, factor V Leiden, and methylenetetrahydrofolate reductase gene mutation in a lupus patient with cerebral venous thrombosis.
    Author: Uthman I, Khalil I, Sawaya R, Taher A.
    Journal: Clin Rheumatol; 2004 Aug; 23(4):362-3. PubMed ID: 15293102.
    Abstract:
    We describe the case of a young Lebanese woman with systemic lupus erythematosus (SLE) and a positive lupus anticoagulant (LAC) who developed right internal jugular vein and sigmoid sinus thrombosis. Coagulation studies showed that in addition to the LAC the patient was heterozygous for the factor V (FV) Leiden mutation, and C677T mutation of the methylenetetrahydrofolate reductase gene. The high prevalence of FV Leiden in the eastern Mediterranean region suggests that we should probably screen our SLE patients in this area, especially those with anticardiolipin antibodies and/or LAC who have no history of thrombosis, for this and other thrombophilia markers. The detection of such abnormalities may have major practical consequences for the long-term management of these patients to prevent further thrombotic episodes.
