We investigated the anticardiolipin antibody (ACA) in a series of patients with cerebral infarction without systemic lupus erythematosus (SLA). Clinical and laboratory data were assessed from a series of 250 non-SLE patients with cerebral infarction who visited our clinic from 1988 to 1990. The concentration of anticardiolipin IgG antibody was measured by an enzyme-linked immunosorbent assay technique. An elevated ACA level was defined as one which was greater than 3 standard deviations above the mean level for normal controls. We examined the CT findings and risk factors for stroke such as hypertension, diabetes mellitus, hyperlipidemia and cardiac disease. Laboratory data such as the platelet count, the presence of lupus anticoagulant and a biologic false-positive test for syphilis were also investigated. Among the 250 patients with infarction, IgG ACA was detected in 22 (8.8%). There was no significant difference in incidence of ACA between the patients with cerebral thrombosis and those with cerebral embolism. On CT scan, multiple cerebral infarcts were noted in 18 of the 22 patients. As regards the location of the infarct, the cerebral cortex together with the basal ganglia was more common than isolated lesions of the cortex or basal ganglia. Concerning the risk factors for stroke, hypertension was noted in 12, diabetes mellitus in 2, hyperlipidemia in 2 and cardiac disease in 2. Lupus anticoagulant and thrombocytopenia were not detected in any of the cases. A biologic false-positive test for syphilis was observed in one case. Dementia was present in 12 of the 22 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Anticardiolipin antibodies (aCL), one of a group of antiphospholipid antibodies which include the lupus anticoagulant (LA), may occur in association with systemic lupus erythematosus (SLE) and are less commonly detected in other diseases. We retrospectively reviewed the clinical and immunological features of 39 consecutive patients with abnormal aCL identified by one laboratory, to examine the spectrum of neurological disease in those patients without SLE. Fourteen patients in this category are described, 6 of whom did not have evidence of LA. All but 1 presented with neurological symptoms. Stroke and migraine dominated the clinical presentation, but many patients had features to suggest the presence of a hypercoagulable state. This study lends support to the concept of a primary antiphospholipid syndrome.

In a 2-year prospective study of 146 patients with cerebral ischemia, we compared vascular risk factors for stroke with clinical and laboratory findings, particularly antiphospholipid antibodies. Ten patients (6.8%) were positive for at least one antiphospholipid antibody; one patient had systemic lupus erythematosus, one had rheumatoid arthritis, and the remaining eight fulfilled criteria for the diagnosis of primary antiphospholipid syndrome. These patients were predominantly male, not necessarily young, and 50% of them did not have any other vascular risk factors; there were no significant clinical or paraclinical differences between these patients and those without antiphospholipid antibodies. Outcome in the 10 patients was good, and platelet antiaggregating drugs proved to be useful in preventing further cerebrovascular ischemic events in our patients.

We describe 2 patients with systemic lupus erythematosus (SLE) who developed an acute psychosis and a cerebrovascular accident after pulse methylprednisolone therapy. A literature review revealed 8 additional patients with SLE with acute central nervous system complications after pulse therapy.

Antiphospholipid antibodies (APA) have been reported to be associated with thrombosis in systemic lupus erythematosus (SLE) and in many other clinical groups. However, although these antibodies have been identified in a substantial number of patients infected with the human immunodeficiency virus (HIV), in this case an association with thrombosis has not been evident. We describe a patient with HIV infection who had anticardiolipin antibodies (ACA) but no lupus anticoagulant (LA) who had recurrent transient ischaemic attacks (TIAs) and a mild stroke.

Lupus anticoagulant and antiphospholipid antibodies are associated with thromboembolic phenomena in individuals both with and without systemic lupus erythematosus. A 32-year-old woman (the index case) with lupus anticoagulant, multiple cerebrovascular events, and a family history of premature stroke raised the possibility of a familial diathesis. Histories or interviews, examinations, and blood tests were obtained for 23 members of four generations of her family. Four individuals had suffered strokes and three more had suffered neurologic symptoms. Two living individuals who had suffered strokes, two individuals with neurologic symptoms, and five asymptomatic individuals had antiphospholipid activity in their blood. In addition, a cousin of the index case was found to have systemic lupus erythematosus and antiphospholipid activity. Elevated concentrations of von Willebrand factor antigen were found associated with some positive lupus anticoagulant assays, the highest concentrations in the two individuals with stroke. The characteristic presentation of the index case and her good response to treatment suggests that further studies of families in whom antiphospholipid antibodies may represent a risk factor for stroke is worthwhile.

The case of a 13 year old girl with renal artery thrombosis and hypertension is described. A cerebrovascular accident and a probable occlusion of the superior mesenteric artery also occurred. Very high levels of 'lupus anticoagulant', anticardiolipin antibodies as well as false positive Venereal Disease Research Laboratory tests were repeatedly shown. Moreover, the patient fulfilled at least four classification criteria for systemic lupus erythematosus, but only a slight positivity for antinucleolar antibodies was present. The striking relation between antiphospholipid antibody levels and clinical events and the treatment of this complex syndrome are discussed.

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.

The case of a young, male patient hospitalized for investigation of a cerebral vascular accident is reported. The investigations led to the diagnosis of disseminated lupus erythematosus associated with the presence of antiphospholipid antibodies (lupus circulating anticoagulant and anticardiolipin antibody). The authors discuss certain notions relating to antiphospholipid antibodies and the thromboembolic, particularly neurological, manifestations thereof.

The frequency of "Lupus anticoagulant" (LA), was studied in 51 patients with systemic lupus erythematosus (SLE), 15 patients with chronic immune thrombocytopenic purpura (ITP) and 3 other patients with prolonged partial thromboplastin time (PTT), two of which had suffered episodes of CVA, and the other had a diagnosis of Paroxysmal Nocturnal Hemoglobinuria. Lupus anticoagulant was determined in each patient by the plasma recalcification time and the Russell's viper venom clotting time. Eight patients with SLE, (15.6%) 6 with chronic ITP (40%) and the three patients with prolonged PTT were positive for LA. All patients with LA were female, whose ages ranged from 19 to 59 years, and all except two patients were under steroid therapy. Thrombocytopenia was the most frequent manifestation in the patients with LA, followed by recurrent fetal death and thrombosis. Only the patients with ITP had hemorrhagic complications and one of them also had CVA in one occasion. The immunosupressory therapy may have played a role in diminishing the frequency of LA in the patients studied.
