The case of a woman with systemic lupus erythematosus with unusual clinical, cutaneous and biologic features and lupus anticoagulant is presented. According to the literature this association is not fortuitous: a new syndrome characterized by the presence of a subgroup of antiphospholipid antibodies has been recognized. The cutaneous symptoms of this syndrome include: leg ulcers, livedo reticularis, widespread cutaneous necrosis and distal cutaneous ischemia. In our patient a nearly complete picture of the clinical and biologic features of this syndrome, including a characteristic retinal vein thrombosis is present.

A 45-year-old man with pernicious anemia presented with sudden loss of vision due to central retinal vein thrombosis, and was found to have anticardiolipin antibodies and a clotting disorder consistent with the presence of a lupus anticoagulant. He was treated with low dose aspirin and has remained free of recurrent thrombosis over a period of one year. The association between lupus anticoagulant and pernicious anemia is rare, having been reported in only one prior case.

Anti-cardiolipin antibody (aCL) in SLE patients reacts with cardiolipin/beta 2-GP1 complex. In order to disclose clinical significance of aCL in patients with SLE, aCL was determined by newly-developed anti-CL.beta 2-GP1 kit [Yamasa] EIA in 58 patients with SLE and the relationship between clinical manifestation of SLE and the presence of aCL was examined. Anti-cardiolipin antibody was positive in 20 patients (34.5%). In 20 SLE patients with positive aCL, livedo reticularis in 7, retinal vein thrombosis in 3, thrombophlebitis in 3 and other vasculo-occlusive episodes were observed as a characteristic clinical features of positive aCL. In contrast, a SLE patient complicated by ileal perforation due to necrotizing angiitis had negative aCL. Other clinical and laboratory features associated with aCL include recurrent fetal loss and thrombocytopenia.

A strong association between the presence of antiphospholipid antibodies (aPLab) and arterial and venous thrombosis was observed during the past decade. aPLab represent a heterogeneous group of immunoglobulins that include the lupus anticoagulant (LA), anticardiolipin antibodies (aCL), and antibodies responsible for false-positive test for syphilis. aPLab react with negatively charged, rarely with neutral phospholipids and/or phospholipid-binding proteins. aPLab are associated with vascular occlusion in autoimmune diseases, e.g. systemic lupus erythematosus (SLE). The role of aCL in ocular vascular occlusive disease involving retinal vessels is unclear. The aim of this study was to determine the relationship between aPLab and occlusive retinal disease. A relationship between aCL (IgG), LA, and thrombotic retinal events has been detected in SLE patients, but no association between aPLab and other occlusive retinal diseases (central retinal vein thrombosis, isolated retinal vasculitis, optic nerve vasculitis). In our study the incidence of aCL IgG was higher in patients with Behcet disease with non-occlusive thrombosis than in patients with retinal occlusive events or in patients without occlusions or thrombosis. It seems that different mechanisms are responsible for these conditions.

A 34-year-old woman with systemic lupus erythematosus and high titres of antiphospholipid antibodies was admitted to hospital suffering a viral illness but developed haemorrhagic and necrotic areas on the neck and anterior chest 7 days following cessation of warfarin. Anticoagulation had been initiated following a retinal vein thrombosis, but was ceased on day 4 of admission when she was found to be excessively anticoagulated (international normalized ratio (INR) > 10). However, at the time of developing the cutaneous lesions, the INR was sub-therapeutic. Histology of a skin biopsy from the neck revealed thrombosis of upper dermal blood vessels without vasculitis, consistent with antiphospholipid antibody-related skin necrosis. This case illustrates one of the cutaneous features that can occur in patients with elevated titres of antiphospholipid antibodies and the importance of closely monitoring anticoagulation in such patients.

A 55 year old woman, known to have systemic lupus erythematosus and protein S deficiency, presented with sudden onset of visual loss in the left eye. Three days previously, she took a herbal phytoestrogen preparation for relief of her menopausal symptoms. Ophthalmological assessment showed a left inferior hemiretinal vein thrombosis. The temporal relation between the onset of visual symptoms and ingestion of this herbal preparation suggested that in this patient with a prior non-manifest prothrombotic tendency, there may be an association between the development of retinal vein thrombosis and herbal phytoestrogen use.
