Abstract:
:The lupus anticoagulant (LAC) and anticardiolipin antibody (ACA) syndromes require particular therapeutic approaches: thrombotic accidents are an indication for oral anticoagulant therapy (OAT), whereas severe thrombocytopenia may require the special treatments used for immunologic thrombocytopenic purpura (ITP). We describe the case of a 21-year-old male who presented with axillary vein thrombosis associated with LAC and ACA at high titers in December 1990. OAT was begun and, due to repeated episodes of thrombocytopenia, high-dose steroid therapy was later added with success. The daily steroid dose was reduced because of patent hypercortisolism, but the platelet count fell to 4 x 10(9)/L. A bone marrow biopsy was characteristic for ITP. Splenectomy was performed in June 1993, and the platelet count rapidly normalized. Platelet antibodies were always detectable before and after splenectomy. The patient is currently asymptomatic, with platelet counts above 300 x 10(9)/L at one and a half years after splenectomy. This case indicates that ACA-associated thrombocytopenia, like ITP and HIV-related thrombocytopenias, can be successfully treated with steroids and splenectomy, even though different pathogenetic mechanisms are responsible for the antibody-induced platelet consumption.
