Retinal vascular manifestation is the most common form of ophthalmic involvement in patients with systemic lupus erythematosus (SLE). Most frequently these consist of cotton-wool spots with or without intraretinal hemorrhages. Although rare, a more severe retinal vaso-occlusive disease, termed retinal vasculitis, has been described. We report on a 37-year-old white female with a 13-year follow-up of chronic discoid lupus erythematosus, which suffered massive bilateral visual loss coincident with the systemic exacerbation of her disease (proteinuria, pneumonia, serositis, leucopenia). The diagnosis of SLE was established with reference to the revised ARA-criteria (American Rheumatism Association). Ophthalmoscopy and fluorescein angiography revealed the typical aspect of a SLE-associated vaso-occlusive retinopathy on both eyes with marked ischemia of the macula. Immediate maximal immuno-suppressive therapy, early performed panretinal photocoagulation and subsequent cryoretinopexy did not stop the progression of the disease. Six months after the initial event vascularisations of the disc and rubeosis iridis occurred, but no secondary glaucoma up to date. In this patient, the almost complete absence of characteristic autoantibodies and immunological markers was striking. The correlation with other lupus manifestations, different therapeutic concepts and prognostic factors in SLE-associated retinal vasculitis are discussed.

A 63-year-old woman with atherosclerotic peripheral vascular disease and the lupus anticoagulant developed ischemia of the right lower extremity, requiring progressive amputations. Pathologic specimens revealed inflammatory vasculitis in multiple arteries. Her serum showed anticardiolipin antibodies in high titer. Treatment with high-dose corticosteroids reversed the ischemic process. In patients with antiphospholipid antibodies, thrombosis is the most common pathologic finding associated with cutaneous lesions and/or gangrene. Vasculitis, although uncommon, is known to occur and may respond to corticosteroid therapy.

Episodic cerebro or retinovascular ischemic events without apparent cause occur in patients with cancer. We report a patient in remission from lymphoma whose multiple episodes of presumed ocular ischemia occurred in the setting of a circulating lupus anticoagulant. Symptoms resolved following therapy with Warfarin.

We report the abdominal computed tomography (CT) findings in a patient with systemic lupus erythematosus who developed signs of an acute abdomen secondary to mesenteric arteritis. Initial CT scan demonstrated ascites and wall thickening of the duodenum and jejunum. After treatment with high dose intravenous steroids, follow-up CT scan demonstrated a normal duodenum and small bowel. This is the first surgically proven case of lupus mesenteric arteritis resulting in bowel ischemia that is demonstrated on CT before and after medical therapy. Lupus mesenteric arteritis should be included in the differential diagnosis of causes of bowel wall thickening and ischemia, especially if mesenteric vessels appear prominent.

Lupus anticoagulants (LAs) and anticardiolipin antibodies (ACAs) are acquired circulating immunoglobulins that cross-react with anionic and neural phospholipids. These factors may display anticoagulant properties in vitro by interfering with phospholipid-dependent coagulation tests. These antibodies are usually not associated with a bleeding tendency. In fact, paradoxically to their name, since the initial recognition they have been related to systemic and cerebral thromboembolisms, despite their in vitro "anticoagulant" properties. We report the clinical and laboratory findings in 4 LAs and ACAs positive patients with brain ischemia.

Treatment of severe hand ischemia a associated to progressive systemic sclerosis and other disorders is controversial. We studied prospectively 45 patients, 41 female and 4 males, over an 11 year period. Age ranged from 16 to 73 years, mean 46. Underlying disease was systemic sclerosis in 30, CREST in 8, overlapping syndrome in 4, systemic lupus in 1 and non rheumatic vasculitis in 2 patients. Treatment consisted of intravenous injection of reserpine, 1 mg, at a superficial arm vein after controlled local circulatory block for 15 min. Regional anesthesia was required in 38 patients. Adequate follow up was obtained in 32 females and 2 males, receiving a mean of 3.1 therapy sessions (range 1 to 13). Morphologic improvement from 3.09 +/- 0.16 to 1.57 +/- 0.13 and functional improvement from 3.6 +/- 0.12 to 1.75 +/- 0.14 (5 grade scoring system), was observed (p < 0.001). These results correlate with adequate rehabilitation confirmed clinically.

The importance of a prothrombotic state as a cause of ischemic stroke in young adults is ill defined. We examined 46 unselected patients under age 50 years with cerebral ischemia for anticardiolipin antibody (aCL) and lupus anticoagulants (LA), over a 3-year-period. Age- and sex-matched patients with other neurologic diseases served as a noncerebral ischemia comparison group to test whether (1) stroke/transient ischemic attacks (TIA) in young people is associated with aCL and/or LA, and (2) their presence is specific to cerebral ischemia. In the stroke/TIA group, 21 patients had aCL or LA and 25 had neither, whereas in the control group, 2 patients had aCL and 24 had neither. Equal numbers of stroke/TIA patients with and without antiphospholipid antibodies (aPL) had other stroke risk factors. Patients with aPL and cerebral ischemia, however, had a more frequent history of multiple events than those without them. These antibodies occur with undue frequency in young patients with stroke/TIA and are not associated with a concurrent diagnosis of systemic lupus in most cases. A coexistent aPL-associated prothrombotic state may be a key determinant of whether patients with atherosclerosis, mitral valve prolapse, or other structural lesions experience recurrent ischemia.

New insights about the following aspects of lupus erythematosus are developed: (1) thrombotic and neurological manifestations associated with the presence of antiphospholipid antibodies; (2) cardiac complications, especially coronary ischemia, conduction abnormalities and valvular involvement; (3) pregnancy, with particular attention to fetal and maternal prognoses, Soulier-Boffa syndrome and congenital atrioventricular heart blocks; (4) subacute lupus erythematosus, bullous lupus and cutaneous manifestations associated with the lupus anticoagulant.

More than a dozen primary hematologic disorders have been associated with ischemic stroke. Inherited deficiencies of antithrombin III, protein C, and protein S have been linked with stroke in case reports; optimal screening requires functional as well as antigenic assays. Antiphospholipid antibodies and lupus anticoagulants are the most frequently identified acquired states associated with ischemic stroke. Polycythemia vera, sickle cell anemia, sickle-C disease, and essential thrombocythemia are the major disorders of formed blood elements causing stroke. Special, step-wise screening for occult prothrombotic entities in stroke patients is recommended for young persons with stroke of uncertain cause, for those with prior venous thrombosis, for those with a family history of unusual thrombosis, and for those with no other explanation for recurrent stroke. Acquired, perhaps transient, abnormalities of platelets, coagulation inhibition, and fibrinolysis may contribute importantly to brain ischemia in synergy with other mechanisms, but at present these remain ill-defined. The contribution of prothrombotic diatheses to stroke is probably underrecognized and warrants further investigation.
