We investigated the clinical and pathologic characteristics of stroke in 234 patients with
systemic lupus erythematosus
. Thirteen patients (5.6%) developed cerebrovascular disease. Cerebral infarction was noted in eight, cerebral hemorrhage in two, and subarachnoid hemorrhage in three. In seven (54%) of these 13 patients, stroke occurred less than or equal to 5 years after
systemic lupus erythematosus
was diagnosed. Among the predisposing risk factors for stroke, hypertension was the most important.
Lupus
anticoagulant was detected in three (38%) and anticardiolipin antibody in three (43% of seven investigated) of the patients with infarction. Evaluation of the clinical manifestations and autoantibodies indicated that renal involvement and high titers of anti-deoxyribonucleic acid antibody were more frequent in the stroke group than in the non-stroke group. Autopsy studies on six of the patients with stroke revealed small infarcts and hemorrhages in all, but in no case was true angiitis observed.
Libman-Sacks endocarditis
was found in two of the three patients with infarction. In conclusion, the important contributory factor to the development of stroke in patients with
systemic lupus erythematosus
is considered to be hypertension mediated by immunologic abnormalities. Antiphospholipid antibodies and
Libman-Sacks endocarditis
are closely associated with occlusive cerebrovascular disease.

Regarding two cases of idiopathic
lupus
valvulopathy, the authors review the various mechanisms responsible for the endocardial lesions in
disseminated lupus erythematosus
. In addition to the classic
Libman-Sachs endocarditis
, there are sclerous forms, ruptures of the chords, thromboses and bacterial superinfections. The role of steroid therapy in the genesis of valvular stenosis is not always determined. A surgical treatment, effective and without major risk, must be advocated at an early stage in the presence of poorly tolerated forms.

Altogether 506 patients with
systemic lupus erythematosus
(
SLE
) aged one to fifteen years were observed from 1961 to 1985 at the clinic of child's diseases of the I. M. Sechenov First Moscow Medical Institute. The disease was noted to undergo evolution during 25 years. The clinical picture and the course of
SLE
in children were elucidated. It is shown that the disease activity and acuity lessened while the patients' survival increased. The clinical picture became less marked. The rate of the signs characteristic of
SLE
(
Libman-Sacks endocarditis
, the nephrotic syndrome, severe lesions of the nervous system, exudative pleurisy and pericarditis) also reduced. The characteristics thus revealed should be taken into consideration in the diagnosis and treatment of
SLE
.

Two cases of
systemic lupus erythematosus
with hemodynamically significant mitral valve dysfunction and associated
lupus
anticoagulant are reported. Both patients underwent valve replacement and both had thrombus formation on the mitral valve, one pre- and the other postoperatively. Both patients suffered a number of extracardiac thromboses at different times in the course of their illness. The contribution of the
lupus
anticoagulant to the thrombotic problems, and its possible relationship to the pathogenesis of
Libman-Sacks endocarditis
are discussed.

A case is presented where the distinction between rheumatic fever and systemic
lupus
as a cause of mitral valvar disease was made by cross-sectional echocardiography. This showed an unusual appearance, consistent with descriptions of
Libman-Sachs endocarditis
from the presteroid era.

A female Caucasian with a history of 18 years of
systemic lupus erythematosus
(
SLE
) developed symptoms and signs of mitral stenosis, but had no history of rheumatic fever. Investigations confirmed severe stenosis, and the diseased valve was replaced by a pericardial xenograft. Histological examination was compatible with steroid-modified
Libman-Sacks endocarditis
. She remains well 24 months postoperatively.

Echocardiography is a valuable modality for imaging thrombi and vegetations. Although patients with
systemic lupus erythematosus
may develop
Libman-Sacks endocarditis
, in which punctate verrucous plaques are found histologically on valvular endocardial tissue, these lesions are ordinarily too small for ultrasonic imaging. We describe a patient with
systemic lupus erythematosus
complicated by systemic embolization, who had a large mobile aortic valve thrombus, which was discovered with the aid of echocardiography and was confirmed by surgical resection.

SLE
is an inflammatory disease of unknown etiology with the potential of affecting virtually all organ systems. Cardiovascular involvement occurs frequently, although it is often mild enough not to cause clinical concern. Pericarditis is most commonly subclinical, noted only on echocardiogram. Pericardial fluid, which can accumulate rapidly enough to cause tamponade, is inflammatory in nature and can totally mimic infection. The occurrence of
Libman-Sacks endocarditis
, usually a pathological diagnosis of little clinical significance, has little if any correlation with the presence of audible murmurs. However, valve replacement is occasionally necessary secondary to sterile destruction. These valvular lesions can also embolize or become infected. The incidence of ischemic coronary disease is increased, both secondary to premature atherosclerosis and, rarely, coronary arteritis. Conduction disease and arrhythmias are infrequently reported in adult patients, but congenital CHB has been noted in children born to mothers who have circulating anti-Ro antibody. Evidence is accumulating that suggests there is a mild cardiomyopathy associated with
SLE
that may be due to thrombotic or inflammatory microvascular coronary disease. Acute clinical myocarditis also rarely occurs. Therapeutically, at present, a reasonable course would seem to be to limit all known possible contributing factors to premature coronary artery and myocardial disease (hypertension, hypercholesterolemia, smoking, steroid therapy, etc), to be vigilant about recognizing the rarer complications associated with
SLE
(infectious pericarditis and endocarditis, coronary arteritis, pericardial tamponade, clinical myocarditis), and to remember that these uncommon complications are indeed uncommon. The importance of vigorously treating systemic hypertension cannot be overstressed.

We reviewed the medical records and autopsy reports of 50 patients with
systemic lupus erythematosus
to determine the clinical and neuropathological features of this disease. Neuropsychiatric disturbances were found in the majority (74%) of the patients, occurring as psychiatric illness only (5 patients), neurological disorders only (15 patients), and both together (17 patients). Central nervous system (CNS) lesions were present in half the patients; embolic brain infarcts (10 patients) and CNS infections (8 patients) were the most common. Cardiac sources of emboli were
Libman-Sacks endocarditis
(5 patients), chronic valvulitis (2 patients), and left side of heart mural thrombus (2 patients). There was no evidence of active CNS vasculitis. Clinical features of thrombotic thrombocytopenic purpura (TTP) developed during the terminal illness in 14 patients, 7 of whom also had pathological evidence of TTP. Correlation between neuropsychiatric disorders and brain lesions could be made in approximately half the patients. This study indicates that cardiac emboli from
Libman-Sacks endocarditis
and TTP are common pathogenetic factors of CNS disease in
systemic lupus erythematosus
, whereas CNS vasculitis is rare.

We performed echocardiography prospectively 4.9 +/- 0.7 years apart (mean +/- SD), in 74 patients with
systemic lupus erythematosus
. On the basis of the first study, the patients were distributed in four groups according to the type of valvular involvement: 7 patients had vegetations (
Libman-Sacks endocarditis
; group 1); 6 patients had rigid and thickened valves with stenosis, regurgitation, or both (group 2); 5 patients had miscellaneous forms of valvular involvement without valvular dysfunction (group 3), as did the 60 controls; and 56 patients had no valvular disease (group 4). The overall prevalence of clinically important valvular disease (groups 1 and 2) was 18 percent. Patients in group 1 were younger than those in group 2 (33.5 +/- 16.7 vs. 47.8 +/- 17.6 years; P less than 0.05), had a shorter mean duration of
lupus
(4.8 +/- 2.2 vs. 10.7 +/- 6.4 years; P less than 0.001), and had received a smaller cumulative dose of steroids (21.5 +/- 13.1 vs. 79.5 +/- 63.4 g of methylprednisolone or its equivalent; P less than 0.05). During the five-year follow-up, one patient in group 1 and five in group 2 required valve surgery, no patient in group 3 had valvular dysfunction, and five patients in group 4 had mild valvular lesions. We conclude that clinically important valvular involvement in systemic
lupus
is relatively frequent and sometimes requires surgery. Echocardiography can identify a subset of lesions (valvular thickening and dysfunction), other than verrucous (Libman-Sacks) endocarditis, that are prone to hemodynamic deterioration.
