Quantitative determination of IgG and IgM antibodies to cardiolipin (anti-CL) was performed with a newly developed sensitive and specific ELISA method. We studied a cohort of 361 unselected patients with various autoimmune rheumatic diseases (ARD), 69 patients with thromboembolic phenomena (TEP) unassociated with ARD, and 267 healthy blood donors (HBD). Anti-CL of at least one immunoglobulin class were found in 42 (11.6%) of the ARD patients, in 3 (4.3%) of the TEP patients (2 with myocardial infarction and 1 with pulmonary emboli), and in 6 (2.3%) of the HBD. In ARD patients anti-CL were more prevalent in patients with systemic lupus erythematosus (SLE) and overlap syndromes. Significant correlations included CNS involvement (particularly seizures) and features of immune hyperreactivity (splenomegaly-lymphadenopathy, ANA, and antibodies to Ro(SSA), U1-nRNP, and double-stranded DNA). No statistical correlation could be demonstrated between the presence of anti-CL and thrombotic events, hematologic disorders, or recurrent abortions in the ARD patients.

Lacunar infarcts in the basal ganglia are known to cause various movement disorders, such as chorea, focal dystonia, and hemichorea-hemiballismus. We report here a case of putaminal lacunar infarction which presented with "painful tonic spasms" of the contralateral limbs. This consisted of paroxysmal brief, painful, flexor contractures of the upper, and occasionally the lower limb. These were not focal seizures but were controlled with carbamazepine, which has been used for the "painful tonic spasms" well-associated with multiple sclerosis. The putaminal infarct we describe is probably related to a lupus anticoagulant and systemic lupus erythematosus.

The clinical and computed tomographic (CT) findings in 17 patients with neurological manifestations of systemic lupus erythematosus were analyzed. Two patients presented with stroke syndromes; they did not have systemic manifestations of SLE at the time the neurological disturbances developed. Of 15 patients with prominent systemic evidence of SLE, 9 presented with stroke syndromes or seizures. CT showed a hypodense lesions representing infarction (7 cases) or hyperdense lesions representing intracerebral hematomas (2 cases). Six patients with gradual onset of neurobehavioral symptoms showed cerebral atrophy without infarction or hemorrhage.

A 13 year old girl with catatonia resulting from cerebral lupus is described. She had concurrent minor epileptic status, but abolition of her seizure activity failed to influence her catatonic state. She recovered after treatment with corticosteroids and immunosuppressive agents. Cerebral lupus should be considered in the differential diagnosis in patients presenting with catatonia.

Two patients with well documented systemic lupus erythematosus developed a syndrome resembling thrombotic thrombocytopenic purpura. Both had severe thrombocytopenia, microangiopathic hemolytic anemia, seizures, and renal dysfunction. Prothrombin time, partial thromboplastin time, thrombin time, and fibrinogen levels were normal; fibrin degradation products were minimally elevated. Histologic evaluation of renal biopsies in both patients confirmed the impression of intravascular thrombosis. Therapy with corticosteroids, other immunosuppressive drugs and splenectomy (in one case) proved unsuccessful. The infusion of fresh frozen plasma, with or without plasmapheresis, reversed the syndrome. This report indicates that patients with systemic lupus may develop a thrombotic thrombocytopenic purpura like syndrome which responds to fresh plasma infusion.

Fifty-one sera from patients with systemic lupus erythematosus (SLE) were studied in order to evaluate the prevalence of anticardiolipin (ACA) and anti-mitochondrial antibodies (AMA) type M5, and also to explore their relationship with the main serological and clinical features of the disease. A group of 25 (49.0%) patients was found to be ACA positive (IgG or IgG and IgM); in this group we found a significantly higher prevalence of false positive VDRL (p less than 0.01), lupus-like anticoagulant (p less than 0.05), and AMA type M5 (p less than 0.01), but not of anti-ds or ss-DNA antibodies. Three sera positive for ACA, AMA-M5 and anti ss-DNA were absorbed with cardiolipin liposomes. Anti-DNA and AMA-M5 showed only a minimal decrease. Central nervous system involvement and especially seizure syndrome was demonstrated with a higher prevalence in ACA-positive groups (p less than 0.05). Despite the results of absorption experiments, the close relationship between AMA-M5 and ACA, false positive VDRL or lupus-like anticoagulant (LLAC) might justify a speculation on the antiphospholipid nature of this antimitochondrial activity.

The study of serum from a patient with C2 deficiency is described. The patient had an episode of pneumococcal meningitis at 5 mo of age with seizures and transient hemiparesis and apparent purpuric skin lesions. He was first admitted to the University of Minnesota Hospitals at 10 yr of age following the discovery of proteinuria accidentally by his mother. Since then he has been admitted repeatedly to this hospital with numerous clinical findings including arthralgia, recurrent abdominal pain, proteinuria, membranous nephropathy, malar butterfly rash, seizures, personality aberrations, and recurrent fever. In June 1971, the patient developed positive DNA and DNP antibodies and positive LE cells. When the C profile was studied before and after recognition of lupus, C1q, C1s, and C4 dropped. C3 levels were elevated as were C5, C6, and C7, C3 proactivator had been reduced in the patient even before he developed lupus. Also because of a traumatic renal biopsy leading to a perirenal hematoma, he required surgery and a blood transfusion. 1 h after blood transfusion, a C2 titer of 23 hemolytic units was detected. Almost immediately levels of C3, C5, C6, and C7 dropped, C8 and C9 remained elevated. The addition of C2 from normal blood permitted dramatic activation of C3. These findings support the view that the rare deficiency in production of C2 predisposes to serious susceptibility to infection, vascular and mesenchymal disease as well as to renal disease and a lupus syndrome.

We report a case of systemic lupus erythematosus (SLE) and recurrent infections associated with isolated Clq deficiency. A 17-year-old girl from Saudi Arabia was hospitalized with seizures, fever, arthralgia, hair loss, oral ulceration and skin rash. Clinical and laboratory findings fulfilled the ARA preliminary criteria for the classification of SLE. Nonlesional skin contained immunoglobulins and C3 at the dermal-epidermal junction. She did not have antibodies to DNA or low C3 or C4. Total serum hemolytic complement activity was absent due to a total selective absence of Clq. There was no circulating inhibitor of Clq activity. The published experience of isolated selective complete Clq deficiency associated with clinical disease is reviewed.

Two patterns of immune aggregate localization were demonstrated by immunofluorescence and electron microscopy in the choroid plexus of four young women with fatal systemic lupus erythematosus. The two patients with granular immune aggregates localized to the basement membrane of the choroid epithelium (membranous choroidopathy) had subepithelial and intramembranous electron-dense deposits and membranous glomerulopathy in their kidneys. The two patients with immune aggregates in the walls of choroidal blood vessels (vascular choroidopathy) had subendothelial electron-dense deposits and proliferative glomerulonephritis. Vascular deposits in the choroid plexus were associated with capillary thrombi and extravasation of fibrinoid material, while isolated membranous choroidopathy had no histopathologic evidence of inflammation. The clinical presentation and serological studies of blood and cerebrospinal fluid were compared in an effort to discriminate between patients with membranous and vascular choroidopathy. All patients had variable neuropsychiatric symptoms and major motor seizures. While those with vascular choroidopathy had more evidence of disease activity in their sera, both groups demonstrated elevated titers of immune-complexed antinuclear antibodies in cerebrospinal fluid. Although both patterns of choroidal localization of immune aggregates were associated with neuropsychiatric dysfunction, we were unable to identify discrete clinical-symptom complexes which differentiated patients with membranous and vascular choroidopathy. These contrasting patterns of choroid plexus immunopathology suggest that factors responsible for differential localization of immune aggregates are not restricted to the renal glomerulus.

Three cases are presented, in two of which the CNS lesions revealed the presence of systemic lupus erythematosus (SLE). The diagnosis of SLE was certain according to the criteria of the ARA, and it was further confirmed by results of renal needle puncture biopsy. Case 1: A 16-year-old adolescent developed choreic movements followed, one month later, by psychotic symptoms suggesting a mixed hebephrenic-catatonic schizophrenic affection. Cutaneous lesions and signs of renal insufficiency 3 months later established that these disorders were related to SLE. A favourable outcome was observed rapidly for the systemic signs, recovery from neuropsychic symptoms being obtained after 3 months only but then in a few days. This course suggests the diagnosis of a "functional psychosis" of lupus origin. Case 2: A 24-year-old woman developed left hemiparesis followed by febrile coma. The slowly favourable course of the disease led to the appearance of a progressive dementia, with numerous epileptic seizures. Although tests for antinuclear antibodies were negative and the ESR was normal, several minor biological anomalies were suggestive of a systemic disease and the diagnosis of SLE was finally established. Corticotherapy produced only slight transient improvement. This progression towards dementia with progressive cerebral atrophy is most probably related to cerebral lupus lesions, the initial coma in the absence of any other apparent cause possibly being the first sign. Case 3: A 47-year-old woman developed simultaneously or separately episodes of arthralgia and uveitis of unknown origin over a 12-year period, and attacks of regressive multilocular neurological deficiency over a 15-year period.(ABSTRACT TRUNCATED AT 250 WORDS)
