Background
Rituximab in patients with antiphospholipid syndrome (APS) is mostly used for treating noncriteria APS manifestations such as thrombocytopenia, and is not a first- or second-line treatment for management of thrombosis. However, at times rituximab is used empirically as adjunct treatment in patients with recurrent thrombosis occurring in spite of anticoagulant therapy (i.e., anticoagulation failure) when combinations of increased anticoagulation intensity, addition of antiplatelet therapy, and reduction of all thrombotic risk factors fail to prevent recurrent thrombosis.[1] [2] Knowledge of its effect on the naturally fluctuating antiphospholipid antibody (APLA) titers is, however, limited. We sought to determine the effect of rituximab on decreasing the magnitude and type of APLA in patients with thrombotic APS.
