Aim

To evaluate the magnitude of venous and arterial thrombosis risk associated with antiphospholipid antibodies (APLs) in adults without systemic lupus erythematosus (SLE).

Methods

Case-control and cohort studies were selected from the MEDLINE and Cochrane Library databases. Two investigators independently extracted data on study design, patient characteristics, venous and arterial events and exposure to APLs, including lupus anticoagulant (LA), anticardiolipin (aCL), anti-尾2 Glycoprotein I (尾2GpI), anti-prothrombin (aPT), anti-phosphatidyl serine (aPS), and anti-phosphatidyl ethanolamine (aPE).

Results

30 studies were included (16,441 patients). The odds ratio (OR) for venous thrombosis was 6.14 (95% confidence interval [CI] 2.74-13.8) in LA-positive patients (5 studies, 1650 patients) and 1.46 (CI 1.06-2.03) in aCL鈥恜ositive patients (12 studies, 5375 patients). None of the associations with more recently identified APLs was significant, but fewer studies were available. For arterial thrombosis, the OR for LA and aCL was 3.58 (CI 1.29-9.92) and 2.65 (CI 1.75-4.00) respectively. The associations between 尾2GpI, aPT and aPS and the risk of arterial thrombosis were also significant, the OR being 3.12 (CI 1.51-6.44), 2.95 (CI 1.31-6.66) and 6.00 (CI 3.07-11.7), respectively. Owing to the heterogeneity of cut-off values for each APL assay, we were unable to perform any sensitivity analysis to determine the optimal value. The presence of low-quality studies may have led to overestimation of the magnitude of the associations.

Conclusions

LA and aCL were significantly associated with an increased risk of thrombosis, especially arterial, in patients without SLE. Systematic thromboprophylaxis in high-risk patients with APL should be evaluated.
