Prevalence of Antiphospholipid Antibodies in Syrian Patients with Thrombosis
Authors
Abstract:
Background: Antiphospholipid antibodies (aPL) are a heterogeneous family of anti-bodies associated with thrombosis and other complications. Objective: To study the prevalence of aPL in patients with thrombosis at Aleppo University Hospitals, Syria. Methods: One hundred and fifty-seven patients with venous and arterial thrombosis and 63 healthy controls were studied. Anticardiolipin antibodies (aCL) and Lupus antico-agulant (LA) were determined. Results: Thirty-four out of 157 (21.7%) patients with thrombosis had some type of aPL. aPL was also found in four healthy subjects (4/63=6.3%). Eighteen patients (11.5%) were positive for LA, 20 (12.7%) for aCL anti-bodies and 4 (2.6%) were positive for more than one aPL. Patients without risk factors for thrombosis and having positive aPL were 23/34 (67.7%). Fourteen out of 78 (17.9%) patients with arterial thrombosis, and 20/79 (25.3%) with venous thrombosis were positive for at least one aPL. Conclusion: Our study showed a significant preva-lence of aPL in patients with thrombosis. It seems that aPL is a risk factor for venous and arterial thrombosis, especially in patients with no conventional risk factors.

The levels of antibodies to cardiolipin and β2-glycoprotein I and polymorphic variants G1691A of Factor V (factor V Leiden, FVL) and G20210A of prothrombin gene (G20210A) were studied in 16 patients with upper-extremity deep vein thrombosis (UEDVT). Most of patients with this syndrome have elevated values of these antibodies. Two of these patients are heterozygous carriers for G20210A and 1 - f...

The prevalence of antiphospholipid and antinuclear antibodies in 102 patients with at least three unexplained miscarriages before a gestational age of 12 weeks, or at least one intrauterine fetal death after 12 weeks, was investigated and compared with the prevalence in 102 normal pregnant controls. Six patients had a history of thrombosis and six had 'lupus-like' disease. Twenty one patients h...
