Antiphospholipid antibody-positive patients can develop bleeding due to capillaritis, microthrombosis, antiprothrombin antibodies, thrombocytopenia, and/or excessive antithrombotic therapy. Clinical characteristics of patients, e.g., renal impairment, elderly, or concomitant medications, are closely related to the risk of bleeding. The management of bleeding in antiphospholipid antibody (aPL)-positive patients is challenging due to the baseline increased risk of thrombosis. If anticoagulation is stopped, it should be restarted as soon as possible once the acute bleeding is controlled; the continuation of anticoagulation despite active bleeding may be required in selected cases. High-dose corticosteroid is the mainstay treatment for diffuse alveolar hemorrhage, lupus anticoagulant-hypoprothrombinemia syndrome, and severe thrombocytopenia; immunosuppressive drugs are also required to improve the long-term outcomes. Hydrocortisone is critical in adrenal hemorrhage patients due to concomitant adrenal insufficiency; despite bleeding, anticoagulation should be maintained as much as possible. Plasma exchange should be considered in catastrophic antiphospholipid syndrome patients with concurrent bleeding. This article will review the causes of bleeding in aPL-positive patients as well as the management strategies.

Background This study was performed to assess adhesion molecules in systemic lupus erythematosus (SLE). Methods This case-control study examined 126 SLE patients and 48 healthy individuals. Blood levels of six adhesion molecules, cortisol, nuclear autoantibody (ANA) and anti-double stranded DNA (anti-dsDNA) titers were measured, while disease activity was assessed using the SLE Disease Activity Index (SLEDAI) score. Results Platelet endothelial cell adhesion molecule 1 (PECAM-1), vascular cell adhesion molecule 1 (VCAM-1), E-selectin, P-selectin, and plasminogen activator inhibitor type-1 (PAI-1) were significantly higher in SLE patients than in controls. Binary logistic regression analysis showed that PECAM-1 and PAI-1 predicted SLE with a sensitivity of 86.5% and a specificity of 81.3%. ANA titers were significantly and positively associated with PECAM-1, VCAM-1, E-selectin, and PAI-1, whereas there were no associations between anti-dsDNA titers and adhesion molecules. Cortisol was negatively associated with PCAM-1 and ICAM-1. There were significant associations between metabolic syndrome (MetS) and E-selectin and PAI-1. 14.8% of the variance in the SLEDAI score was explained by the regression on PECAM-1 and MetS. Conclusions Our data show that adhesion molecules, especially PECAM-1, are significantly associated with SLE and disease activity, suggesting that they play a role in SLE pathophysiology. While MetS, ANA titers and cortisol levels modulate adhesion molecule levels, these associations do not explain the increased levels of adhesion molecules in SLE. Increased levels of adhesion molecules are new drug targets in SLE.
