Patients with systemic lupus erythematosus may develop premature atherosclerosis, notably coronary artery disease. A group of 10 patients with peripheral vascular disease presenting with intermittent claudication or gangrene were studied from a group of 563 patients followed prospectively at the Wellesley Hospital Lupus Clinic. These 10 patients were compared with the next lupus clinic patient matched for age and sex, with respect to demographic characteristics and risk factors. The patients and controls did not differ significantly in lupus activity criteria count, partial thromboplastin time, the number with antibody to cardiolipin, number receiving steroids or mean steroid dose, family history of atherosclerosis, hyperlipidaemia, smoking, hypertension or use of oral contraceptives. The risk factors for developing peripheral vascular disease were a longer duration of systemic lupus erythematosus and a longer duration of use of steroids. Eight of the 10 patients had coexistent coronary artery disease or transient ischaemic attack.

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.

A 65-year-old white female without lupus developed concurrent thrombocytopenia and disturbed arterial circulation to the brain and lower leg (a minor stroke and lower leg gangrene, necessitating amputation). Laboratory studies disclosed high levels of anticardiolipin antibodies. Anticoagulant treatment restored circulation in the remaining leg and also normalized platelet levels. This case emphasizes the importance of searching for anticardiolipin antibodies in unexplained thrombotic events.

The antiphospholipid syndrome (characterized by the presence of circulating lupus anticoagulants or anticardiolipin antibodies) was first recognized in patients with systemic lupus erythematosus (SLE), but the syndrome can also exist in the absence of SLE. The clinical features include arterial or venous thrombosis, recurrent abortion, neurological problems, and various cutaneous disorders including thrombophlebitis, livedo reticularis, atrophie blanche, leg ulcers, and gangrene. In some cases, antiphospholipid antibodies may play a role with other recognized syndromes characterized by vascular occlusion, such as Sneddon's syndrome (livedo reticularis with cerebrovascular occlusion) and Degos' disease.

Ten patients with circulating lupus anticoagulant who presented with cutaneous vascular disease and cerebrovascular disease are presented. Cutaneous manifestations were gangrene, thrombophlebitis, ulcers, and livedo reticularis. All 10 patients had cerebral infarction. The relationship between the cerebral and cutaneous vascular changes and the presence of lupus anticoagulant is supported by a common noninflammatory vascular thrombosis histologically in these patients and by the presence of similar pathologic and clinical findings in patients with the lupus anticoagulant syndrome.

Most patients with lupus anticoagulant (LA) activity have coincident antibodies to a group of negatively charged phospholipids, and its is suggested that LA and anticardiolipin tests detect antibodies with overlapping specificities. Some discordance between the two assays has been described, however. One patient presenting with severe thrombotic disease (recurrent deep vein thrombosis, pulmonary embolism, inferior venocaval obstruction, myocardial infarction, and digital gangrene) showed strong LA activity in February 1987. An enzyme linked immunosorbent assay (ELISA) showed no binding to the negatively charged phospholipids cardiolipin, phosphatidylserine, and phosphatidic acid, but binding to zwitterionic phosphatidylethanolamine (PE) was demonstrated. Inhibition studies and affinity purification confirmed this finding. Interestingly, the serum did not bind to the kaolin cephalin clotting time reagent when used as antigen in an ELISA. The pathogenic significance of anti-PE antibodies and their relation to LA remains to be clarified. Further studies of the occurrence of anti-PE antibodies in patients with LA activity who have negative anticardiolipin tests are suggested.

This retrospective study of 295 patients extends the earlier findings of an association between lupus anticoagulation and thrombosis by demonstrating the occurrence of cutaneous lesions related to the coagulation defect in 70 patients. The most frequent cutaneous associations were thrombophlebitis, skin ulcer, gangrene, haemorrhage, and cutaneous necrosis. Of the patients with skin lesions, 41% had the skin lesion as the first sign of the disease. It is important to recognize this association because nearly 40% of the patients with skin lesions have multisystem thrombotic phenomena in the course of the disease.

Two patients with livedo vasculitis and microthrombosis of the dermal vessels and one patient with symmetric gangrene of both hands are presented. Their only biologic abnormality was the presence of a lupus-type circulating anticoagulant and an increased level of anticardiolipin antibodies. These observations and the few previously reported cases of cutaneous disorders associated with abnormal antiphospholipid activity suggest that the common pathologic process is thrombosis.

A 77 year old man with digital gangrene of his left hand had anti-phospholipid antibodies, the lupus anticoagulant and antcardiolipin antibodies. This patient, as far as we are aware, is the first elderly person to present in such fashion with this uncommon syndrome.

An 80-year-old white man presented with gangrenous lesions involving several distal phalanges of his left hand and an elevated erythrocyte sedimentation rate (ESR). Temporal artery biopsy showed patchy destruction of the internal elastic lamina by mononuclear cell infiltration, consistent with the diagnosis of temporal arteritis. After amputation of gangrenous lesions, he was discharged taking prednisone (60 mg/day). Twelve months after discharge there was no recurrence of ischemic manifestations and ESR was normal. Association of digital gangrene and elevated ESR should alert the clinician toward this diagnosis once other diseases such as atherosclerosis, scleroderma, lupus erythematosus, periarteritis nodosa have been ruled out.
