Chorea as a manifestation of SLE is infrequent (1% of all cases of SLE). A new case is reported herein. The patient, a seventeen-year-old female, was admitted with a one-week history of choreic movements of the left half of the body and arthritis of both wrists. Biologic findings confirmed the diagnosis of SLE with presence of an antiprothrombinase circulating anticoagulant. Findings upon cerebral CT scan and magnetic resonance imaging were normal. Clinical symptoms worsened despite corticosteroids in a daily dosage of 1 mg/kg with three pulses of 800 mg methylprednisolone. High-dose neuroleptic therapy was given and three plasma exchanges were performed. A dramatic improvement in clinical symptoms and biological anomalies occurred and persisted during follow-up which now exceeds one year. The lack of MRI anomalies suggests that the pathogenesis of SLE-associated chorea involves functional neurone activation by immune complexes; the dramatic effectiveness of plasma exchanges may obviate the need for using immunosuppressant agents in patients who fail to respond to corticosteroids.

A woman with chorea gravidarum in the absence of SLE is described. She later developed severe chorea while using the contraceptive pill, and high titered antiphospholipid antibodies were detected in serum. A rapid recovery after high dose i.v. methylprednisolone was observed. Deterioration occurred in a later pregnancy.

A case of disseminated lupus erythematosus with chorea is reported. CT was normal. Magnetic resonance imaging showed multiple focal lesions on T2-weighted sequences, predominating in the periventricular white matter. This MRI pattern did not change in a second MRI investigation, 7 months later. The contribution of MRI to our understanding of the neurolupus pathophysiology is discussed.

As many as 30 patients suffering from systemic lupus erythematosus (SLE) with the clinical signs of central nervous system derangement were examined. The mean age of the patients was 31.1 years. Using EIA, antibodies against cardiolipin (a-CL) were detected in 21 patients (70%). A-CL were revealed in all the patients with cerebral circulation impairment (CCI), choreic hyperkinesis, and convulsive syndrome. A-CL were discovered in 12 out of 18 SLE patients suffering from migraine-like headaches and in 4 out of 5 patients with mental disorders. Antibodies reacting with cardiolipin were mostly represented by the IgM isotype (80%) whereas a-CL-IgG were only identified in 13% of the patients, being associated in all the cases with a-CL-IgM. The high level of a-CL-IgG in blood serum was recorded in patients with the gravest patterns of nervous system derangement: CCI, occlusion of the retinal artery, psycho-organic and convulsive syndromes. All these patients demonstrated generalized reticular livedo. The high levels of a-CL-IgM were observed in SLE patients with choreic hyperkinesis and migraine-like headaches. Thus, the studies made it possible to trace the relationship between the development of certain neurological disorders (CCI, chorea, convulsive syndrome) in SLE patients and a-CL.

A child is reported with chorea as the initial presentation of acute lymphoblastic leukemia. Subsequent laboratory studies revealed marked eosinophilia and a lupus anticoagulant. No peripheral or central nervous system lymphoblasts were observed. The chorea, eosinophilia, and lupus anticoagulant all resolved once remission of the acute lymphoblastic leukemia was induced. It is suggested that acute lymphoblastic leukemia be included in the differential diagnosis of chorea and eosinophilia in childhood.

Antiphospholipid antibodies are a relatively heterogeneous mix of immunoglobulins with binding specificities for negatively charged or neutral phospholipids. Currently, the most commonly detected antiphospholipid antibodies include the anticardiolipin antibody, the lupus anticoagulant, and an antibody implicated in false-positive VDRL testing. Recently, a clinical syndrome of vaso-occlusive disorders associated with antiphospholipid antibodies has been identified and may result from immune-mediated disruption of endothelial function. This clinical syndrome encompasses arterial and venous thrombosis, recurrent fetal loss, neurologic dysfunction (eg, migraine, chorea, and encephalopathy), systemic and pulmonary arterial hypertension, and endocardial disease. Although most commonly associated with systemic lupus erythematosus, the antiphospholipid antibody syndrome also has been identified in patients with vaso-occlusive disease without systemic lupus erythematosus. Recently, identification of antiphospholipid antibodies has been facilitated by the development of a more sensitive assay for anticardiolipin antibody. In this article, case histories of three patients with arterial thrombosis and associated anticardiolipin antibodies, including the first associated case of terminal aortic thrombosis, are reviewed and the subject of the antiphospholipid antibody syndrome is discussed.

An 11-year-old boy developed florid choreic movements in his right extremities after having had an episode of febrile illness. He was evaluated at our hospital where MRI disclosed a honeycomb-like low signal intensity area rimmed by a thin Gd-enhanced layer in the left putamen. Arteriography revealed the lenticulostriate arteries being segmentally narrowed and a "ground glass" staining was observed in the left putamen in late venous phase. Sydenham's chorea, that had been the initial impression, was not substantiated because of negative pharyngeal culture for streptococci, negative ASLO/ASK titers and because of lack of clinical stigmata of rheumatic fever. However, prothrombin time was prolonged, and activated partial thromboplastin time (APTT), that had been also prolonged, was not normalized by adding healthy serum, indicating the presence of lupus anticoagulant. VDRL was false positive and anticardiolipin antibodies, both IgM and IgG classes, were also detected. However, systemic lupus erythematosus was unlikely in view of negative antinuclear antibody and LE phenomenon. He deteriorated rapidly due to development of severe bilateral chorea, thereby he was unable to walk or feed himself. He received a 3-day course of mega-dose intravenous methylprednisolone, that temporarily lessened the chorea, but soon it became worse. A second course of mega-dose methylprednisolone was given, followed by daily maintenance dose of prednisolone. His chorea gradually improved in severity and after 2 months only a trace of choreic movements was detected in his hands. He has been followed at our outpatient clinic where he no longer shows chorea and the APTT has improved to nearly normal time.(ABSTRACT TRUNCATED AT 250 WORDS)

An association between anti-phospholipid antibodies and different disorders of the central nervous system has been described recently. We used an ELISA technique and detected anti-cardiolipin antibodies of the IgG or IgM variety in a series of 10 patients: 4 had occlusive stroke, 2 brain hemorrhage, 2 chorea, 1 a Sneddon syndrome and 1 vascular cephalea. The diagnosis of primary anti-phospholipid syndrome was suggested after ruling out systemic lupus in all patients.

Chorea has been related to the presence of antiphospholipid antibodies (a-PL) in the context of systemic lupus erythematosus (SLE). Here we report the case of a 13-year-old girl with a-PL antibodies, who had developed thrombophlebitis at the age of 11 years and chorea two years later, in the absence of clinically evident SLE. Serological tests revealed a false positive test for syphilis, a prolonged activated partial thromboplastin time, hypocomplementaemia and positive anti-DNA antibodies.

Neurologic manifestations, afflicting up to 70% of SLE patients, include psychosis, seizures, chorea, neuropathies, and stroke. MRI is useful in evaluation of lupus patients and several reports have documented cerebral atrophy or focal hyperintensities. We report an unusual MRI appearance in a 56-year-old woman with SLE, diagnosed on the basis of pleuritis, lymphopenia, anti-DNA antibodies, and neurologic involvement. She reported recent onset of Raynaud's phenomenon and generalized macular rash. She presented after two months of gradual deterioration with memory loss, flattened affect, dysphagia, dysarthria, anomia, and somnolence, without focal neurologic signs. Investigations included elevated ESR, reduced complement, normal CSF without oligoclonal bands, negative viral serology, normal hormone and vitamin levels, normal renal and hepatic function. Neuropsychologic testing showed widespread impairment (WAIS-R: FSIQ-63; WMS-69; DRS-98; RCPM-14; WAB AQ-78.8). CT was normal but MRI showed strikingly symmetric, confluent hyperintensities extensively involving cerebral and cerebellar white matter on T1 and T2 weighted scans. Basal ganglia and subependymal and subcortical white matter were spared. Treated with prednisone, the patient made a gradual, but incomplete, recovery. These MRI findings may reflect widespread vasculopathy or direct immunologic brain insult with or without immunologic blood-brain barrier disruption.
