Antiphospholipid antibodies and the risk of thrombocytopenia in patients with systemic lupus erythematosus: A systematic review and meta-analysis

摘要

Background: According to criteria for the classification of Systemic Lupus Erythematosus (SLE), thrombocytopenia is one of the disease-defining hematologic disorders. Since the recognition of Antiphospholipid Syndrome (APS), thrombocytopenia was frequently reported but several studies yielded contradictory results on the association between aPL-positivity and thrombocytopenia.
