Antiphospholipidantibodies in systemic lupus erythematosus patients

Overview

Different levels of coagulation cascade may be variously altered by antiphospholipid antibodies(APA). The aPL may cause different clinical symptoms, typically thrombosis, recurrent miscarriagesand thrombocytopenia. Aim: to analyse retrospectively occurrence of lupus anticoagulant (LA) andAPA (mixture of phospholipids – cardiolipin, phosphatidic acid and phosphatidylserin in thecommercial set) in systemic lupus erythematosus (SLE) patients and to correlate these parameterswith the history of thrombotic events. Material and methods: A group of 46 patients who fulfilledACR criteria for SLE was evaluated. Nonspecific parameters of inflammation, autoantibodies (ANA,anti-ENA, anti-dsDNA,anti-Ro, anti-La, anti-Sm, anti-snRNP),lupus anticoagulant andantiphospholipidantibodies – cardiolipin, phosphatidic acid and phosphatidylserin in commercial set (APA test)were followed. A history of thrombotic events was evaluated. Results: In this group there were 13LA positive, 33 LA negative, 18 APA positive, and 28 APA negative patients. Forty thrombotic eventswere detected. Venous thrombosis was detected in 62% in a group of LA positive and in 18% in LAnegative patients (p
