Thirty-three cases of systemic lupus erythematosus in women are studied in retrospect. Eight patients (24 percent) presented a total of ten neuropsychiatric episodes that could be attributed to the underlying disease. The neuropsychiatric manifestation that was most often observed was cerebrovascular stroke (40 percent) followed by psychic disturbances and convulsions. A facial paralysis coinciding with an hypertensive crisis was noticed in one case. Another patient presented a peripheral sensitive neuropathy. Five episodes occurred prior to diagnosis or during the first year of the disease. In two patients the neuropsychiatric manifestations constituted the initial symptom of systemic lupus erythematosus. ECG proved to be one of the most valuable diagnostic tools among the complementary studies. It was altered in cases of organic pathology and normal when disturbances were of psychic origin. The C3 fraction of the serum complement revealed a definite difference between patients with and without neuropsychiatric manifestations. Concentrations were lower in persons which psychic disturbances than in patients without them. The pathogenesis of neuropsychiatric manifestations of systemic lupus erythematosus is discussed. They cannot be attributed exclusively to coagulation disturbances nor to treatment with corticosteroids. The immediate prognosis of neuropsychiatric episodes was good: there was partial or total recuperation in eight of the ten episodes. However, the long-term course of systemic lupus erythematosus shows that these manifestations represent an unfavourable prognostic factor in this disease.

Seven cases of SLE with concomitant neurological syndromes are reported. In 2 cases brain stroke with right-sided hemiplegia and aphasia developed, in the remaining cases brain-stem stroke with subarachnoid haemorrhage, progressive hemiparesis and signs of intracranial hypertension, chorea, status epilepticus in terminal uraemia were observed. In one case myasthenia coexisted. Severe neurological syndromes were preceded by signs of involvement of other organs and in most cases by low-grade signs of central nervous system involvement. Treatment with corticosteroids and immunosuppressants resulted in significant improvement without complete remission. A retrospective survey of clinical material showed that modern therapeutic methods have improved the prognosis in systemic lupus erythematosus independently of central nervous system involvement.

The case of a young female patient with hemiplegia and aphasia of sudden onset as the initial manifestation of systemic lupus erythematosus is reported. The arteriographic study showed occlusion of the proximal portion of the left anterior cerebral artery and of the trifurcation of the left middle cerebral artery. The neurological manifestations in systemic lupus erythematosus may appear before there is any clinical evidence of involvement of others organs. The authors think that systemic lupus erythematosus should be suspected in every young female patient with acute cerebrovascular accident of unknown etiology.

Methylated amino acids are excreted in urine upon degradation of some tissue proteins. The urinary excretion ratios of NG,N'G-dimethylarginine (syn-DMA) and NG,NG-dimethylarginine (unsym-DMA) were studied in healthy adults and in patients with various diseases. The normal ratio of sym- to unsym-DMA in urine was 0.98 and ranged from 0.71 to 1.33; ratios were not significantly different in multiple sclerosis, cerebrovascular accident, cancer, and systemic lupus erythematosus. However, patients with liver, disease, including chronic active hepatitis, were found on average to have a significantly altered ratio of 0.79, range 0.49-1.30, owing to an increase in the excretion of unsym-DMA. Hence measurements of the urinary excretion of dimethylarginine could become a useful aid in assessing recovery of liver cells in patients with chronic liver disease.

Right and left heart pressures, left ventricular volumes, indices of contractility, myocardial wall stiffness, and coronary blood flow were determined in five young women with systemic lupus erythematosus (SLE) during diagnostic right and left heart catheterization. Examinations revealed (1) increases of right and left ventricular enddiastolic pressures; (2) decreases of cardiac output, stroke volume, ejection fraction, contractility indices, diastolic left ventricular volume inflow; (3) decreases of pharmacologically induced coronary vasodilation in SLE. The results demonstrate impaired pump function, reduced contractility, increased myocardial wall stiffness, and decreased coronary vascular reserve in SLE. It is concluded that lupus cardiomyopathy associated with an impairment of left ventricular function may be apparent in young women with SLE who have no clinical signs of cardiac dysfunction.

Haemodynamic functions, myocardial contractility, and coronary blood flow were measured in five young women with systemic lupus erythematosus. There had been no signs of cardiac involvement. Left and right heart catherterisation excluded abnormal pressure gradients and valvar regurgitation. But left ventricular end-diastolic pressures were considerably raised while cardiac output, stroke volume, ejection fraction, and left ventricular compliance were decreased. Isovolumic indices of myocardial contractility were altered, corresponding to a decreased contractile state of the myocardium. Coronary blood flow was moderately increased at rest, but pharmacologically induced coronary vascular reserve was markedly reduced. It is concluded that in young women with this disease there may be, in the absence of clinical signs of cardiac involvement, haemodynamic abnormalities which must be ascribed to the consequences of a lupus cardiomyopathy.

We retrospectively evaluated the clinical outcome of 45 female and 11 male patients with biopsy-proven lupus nephritis, followed at our hospital between February 1974 and February 1990. In the majority signs of nephritis were present at the time systemic lupus erythematosus was diagnosed (range: -42-156 months) and the median time from onset of nephritis to biopsy was 2 months. The median follow-up from the time of the biopsy was 53.5 months (range: 2-192), the median age at biopsy 25 years and the median serum creatinine level 1.2 mg/dl. Initial renal biopsies had the following histopathological classes according to the World Health Organization criteria (n): I (2); II (10); III (10); IV (28); V (5); VI (1). Over the study period active episodes were treated with high-dose oral prednisone alone or combined with intravenous nitrogen mustard and oral chlorambucil (1974-75), azathioprine (1978-86), cyclophosphamide (1986-90) and/or plasma-exchange (1976-84). These strategies were based on literature data or multicenter studies in which we participated. Eight patients developed end-stage renal disease (ESRD) (median: 47 months post-biopsy; range: 20-120). In these, initial biopsies showed class IV in seven, and class V in one. Confounded risk factors for ESRD were class IV biopsy, male gender and serum creatinine level above 1.4 mg/dl. The calculated proportion without ESRD 5 years post-biopsy was 87% (95% confidence limits: 98-76%), and at 10 years 70% (95% confidence limits: 90-49%). Five patients (11.2%) died; causes of death were cerebrovascular accident (n = 2), cerebral lupus (n = 2) and S. aureus sepsis (n = 1).(ABSTRACT TRUNCATED AT 250 WORDS)

Antibodies directed against phospholipids are highly associated with episodes of venous and arterial thrombosis, which are often recurrent. There seems to be a skewed frequency of cerebral thrombosis when the arterial circulation is affected. Clinical clues that should lead to evaluation for aPL include stroke in a young adult, recurrent thrombosis or miscarriage, and thrombocytopenia. Associated laboratory abnormalities include a biologically false-positive test for syphilis, abnormal antinuclear antibody titers, and a high erythrocyte sedimentation rate. If the activated partial thromboplastin time is prolonged on routine screening and does not correct with mixing studies, a lupus anticoagulant should be suspected. However, more sensitive and specific tests are usually necessary to detect aPL. Many in vitro and more recently in vivo systems strongly suggest that aPL may be directly implicated in the pathogenesis of thrombosis. Optimal management of patients with aPL-associated thrombosis is unknown. The use of aggressive therapeutic management schemes with such agents as warfarin or corticosteroids is sometimes required.

Racial differences in stroke are known to exist with persons in the black race having a higher morbidity, mortality and incidence of stroke compared to whites. We evaluated coagulation factors in black and white stroke patients and compared the results between races. D-dimer was elevated more frequently in blacks than whites to a statistically significant degree. There were non-significant trends for blacks to have a positive lupus anticoagulant, low protein C and protein S, higher platelet factor 4, and hyporesponsive platelets to 10 microM epinephrine. The significance of these findings in understanding racial differences in stroke is discussed.

A case of antiphospholipid syndrome (APPS) is presented. A 33-year-old female presented with a right hemispheric stroke secondary to thrombosis of the middle cerebral artery. Shortly thereafter, she developed thrombosis of the right brachial artery. Despite thrombolytic therapy, progressive occlusion of this artery occurred as demonstrated by a follow-up angiogram. The patient had a history of multiple recurrent spontaneous abortions. Lupus anticoagulant, anticardiolipin antibodies, and VDRL were positive on two different occasions. The angiographic findings of multiple and progressive arterial thrombosis in young women should alert the angiographer to the possibility of APPS.
