We describe a 26-year-old white female with a history of Raynaud phenomenon, erythema nodosum, polyarthralgias, migraine, vertigo, seizures, transient ischemic attacks, one fetal loss, and false positive VDRL, who developed milk hypertension without overt lupus nephritis. She had positive antinuclear antibodies (ANA) and double-stranded deoxyribonucleic acid (dsDNA) antibodies. The lupus anticoagulant test (LAC) and cardiolipins antibodies (aCL) were positive. She was diagnosed as having a Systemic Lupus Erythematosus-like illness (SLE-like) with 'secondary' antiphospholipid syndrome (APS). Renal spiral computed tomography (CT) with intravenous (IV) contrast showed bilateral renal artery stenosis. Anticoagulation with acenocumarol was started. She became normotensive without antihypertensive drugs five months later. A follow-up renal spiral CT showed complete recanalization of both renal arteries, making thrombosis the more likely culprit pathology in the stenosis. After two years follow up the patient is normotensive. She remains on acenocumarol.

We present a case study of a 46-year-old woman with a psychotic depressive illness of 2 months' duration with the coexisting medical diagnoses of critical aortic stenosis, severe labile hypertension, renal failure necessitating hemodialysis of 7-years' duration, and systemic lupus. Because of unresponsiveness to an antidepressant drug regimen, severe motor retardation, mutism, and refusal of food and fluids by mouth, an urgent indication for electroconvulsive therapy (ECT) was established. However, the patient refused ECT, and to allow its initiation, a court order was obtained. In view of the coexisting diagnoses of critical aortic stenosis, labile hypertension, and renal failure, ECT represented a substantially increased risk in this patient because of severe arterial hypertension and tachycardia. The patient was successfully managed during each ECT, using a combination of metoprolol by mouth, which was supplemented by i.v. esmolol immediately prior to the application of the ECT stimulus, and sodium nitroprusside, which was infused for several minutes prior to the seizure and thereafter to attenuate arterial hypertension. Nevertheless, sudden death, a well-known complication of critical aortic stenosis, occurred 96 hours after the fourth ECT.

Parkinsonism complicating systemic lupus erythematosus (SLE) is extremely rare. We report two girls with SLE who developed extrapyramidal parkinsonian features after an initial stormy course. One patient presented with generalized tonic clonic seizure and was then noted to have akinetic mutism and masked face. MRI brain revealed abnormal signals in bilateral basal ganglia and single photon emission computed tomography (SPECT) showed hypoperfusion in the same area. EEG background was slow and disorganized. Symptoms persisted despite high dose intravenous methylprednisolone and cyclophosphamide. Intravenous immunoglobulin (IVIG) was prescribed empirically and was followed by complete recovery. Both EEG and MRI brain were normal on follow-up. The second patient was found unconscious and then developed bradykinesia, mutism and shuffling gait. MRI and SPECT both detected abnormalities in basal ganglia. EEG was slow. Intravenous immunoglobulin was given after methylprednisolone and cyclophosphamide. This was followed by clinical improvement. The pathogenesis of basal ganglia injury in SLE, along with the management of cerebral lupus and the mechanisms of action of IVIG, are discussed.

Consider the high-cost impact of uncommon diseases. It's not cost-efficient for most health plans to develop disease management programs for uncommon chronic diseases such as lupus, seizure disorders, or MS, but that doesn't mean patients with these ailments don't need the support services a DM approach would provide. See how one DM vendor is successfully filling this gap in care.

Neurologic complications of systemic lupus cerebritis are not as well known in children as in adults. Twenty-five children with neurologic complications were identified after reviewing the hospital medical records of 86 children with systemic lupus erythematosus. Seven children (28%) had neurologic symptoms at the time of initial diagnosis of systemic lupus erythematosus; median time between diagnosis of systemic lupus erythematosus and onset of neurologic complications was 1 month (range 0-5 years). Seizures were the most common neurologic symptoms overall, but headaches were the most frequent neurologic manifestation in children without a previous diagnosis of systemic lupus erythematosus. Sixteen children had seizures, and 12 children had seizures as the initial central nervous system involvement. Almost all children who developed seizures had an established diagnosis of systemic lupus erythematosus; only one child had seizures that led to the diagnosis of systemic lupus erythematosus. No patient had status epilepticus, and, in general, seizures were not difficult to control. In six children, headache was the initial symptom of central nervous system involvement. Five children had lupus cerebritis, three children had stroke, and two had isolated cranial neuropathies. Chorea was seen in only two cases, and three children had pseudotumor cerebri. Treatment with high-dose intravenous methylprednisolone led to a good response in 18 children; cyclophosphamide was required in 6 patients and plasmapheresis in 1 child. Outcome was generally good, although one child developed fulminant cerebritis with intracranial hypertension and died.

A subgroup of children with arterial ischemic stroke in the pre- or perinatal period present with delayed diagnosis. We identified 22 children who met the following criteria: (1) normal neonatal neurological history, (2) hemiparesis and/or seizures first recognized after two months of age, and (3) computed tomography or magnetic resonance imaging showing remote cerebral infarct. Laboratory evaluations included protein C, protein S, antithrombin, activated protein C resistance screen (APCR), Factor V Leiden (FVL), prothrombin gene defect, methylene tetrahydrofolate reductase variant (MTHFR), anticardiolipin antibody (ACLA), and lupus anticoagulant. Not all children received all tests. Age at last visit ranged from 8 months to 16.5 years (median 4 years). Twelve were boys. Fourteen had left hemisphere infarcts. Median age at presentation was 6 months. Eighteen had gestational complications. Fourteen children had at least transient coagulation abnormalities (ACLA = 11, ACLA + APCR = 1, APCR = 2 with FVL + MTHFR = 1); six of these children had family histories suggestive of thrombosis. Cardiac echocardiogram was unremarkable in the 15 tested. Outcomes included persistent hemiparesis in 22; speech, behavior, or learning problems in 12; and persistent seizures in five, with no evidence of further stroke in any patient. The persistence and importance of coagulation abnormalities in this group need further study.

The aim of this study was to evaluate the frequency and intensity of cerebral atrophy using CT scanning and the possible relation to corticosteroid therapy or disease in systemic lupus erythematosus (SLE) and to analyse the relationships between cerebral atrophy and activity disease and neuropsychiatric manifestations in lupus patients. We studied 107 consecutive SLE patients (American Rheumatology Association 1982 criteria) who were taking steroid drugs at the time and not selected for any particular manifestation (group 1). A complete clinical, neurological and laboratory evaluation was performed. The American College of Rheumatology's classification for neuropsychiatric manifestations and SLE disease activity index for activity were employed. Group 2 comprised 39 non-SLE patients with oral chronic steroid use (1 mg/k/day for more than 3 consecutive months); 50 normal individuals were the controls (group 3). There were no demographic differences between the groups. Brain CT was performed in all individuals and the frequency and the intensity (minimal, moderate and severe) of atrophy analysed, through well-defined measures and indices, by two neuroradiologists. Cerebral atrophy was significantly more frequent in groups 1 and 2 than in group 3, but with no significant difference between groups 1 and 2. The severity of cerebral atrophy was significantly higher in SLE patients (p<0.05), independent of steroid dose or duration of disease. In both groups no patient presented severe atrophy. Lupus patients with and without cerebral atrophy presented neuropsychiatric manifestations and activity disease in a similar proportion. The more frequent neuropsychiatric manifestation in lupus patients with cerebral atrophy was seizures (p<0.05). Chronic glucocorticoid therapy was responsible for cerebral atrophy, with a comparable incidence in both lupus and non-lupus patients compared to age and gender-matched normal subjects untreated with glucocorticoids. The disease activity was not related to cerebral atrophy in group 1 and seizures were the neurologic manifestation related to cerebral atrophy. The severity of the cerebral atrophy was independent of steroid dose, or duration of treatment. Moreover, the disease itself contributes to the severity of this process, but not to the development of cerebral atrophy.

This study investigated the use of anti-ribosomal P antibodies in the diagnosis of cerebral complications of systemic lupus erythematosus using two different methods---western blotting and enzyme-linked immunosorbent assay. Anti-ribosomal P antibodies in patient serum were detected in both methods using a purified ribosomal P antigen substrate. Western blotting detected anti-ribosomal P antibodies with a 90% specificity for systemic lupus erythematosus in 56% of patients with the disease. The detection of anti-ribosomal P antibodies by western blotting in patients with systemic lupus erythematosus was significantly associated with psychosis and/or seizures; detection was positive in 90% of patients with these cerebral complications and in 41% of those without. Elevation of the level of anti-ribosomal P antibody, as measured by enzyme-linked immunosorbent assay, was 99% specific for systemic lupus erythematosus in 44% of patients with systemic lupus erythematosus that was not associated with cerebral involvement. We conclude that the measurement of anti-ribosomal P antibodies by western blotting is helpful in the diagnosis of cerebral lupus in selected patients.

Neuropsychiatric involvement in systemic lupus erythematosus (NPSLE) is considered as one of the major manifestations of the disease. Epilepsy has been documented in about 10% of patients with systemic lupus erythematosus (SLE). It is well known that vascular damage in SLE occurs because of multiple mechanisms including hypercoagulation. It has been recently reported that in SLE patients raised levels of homocysteine are associated with arterial thrombosis. Hyperhomocysteinaemia is a condition due to both genetic and non-genetic factors. The most common genetic defect in homocysteine metabolism is a decreased activity of a common 5,10-methylenetetrahydrofolate reductase (MTHFR) variant (677C -->T, a thermolabile form). In this paper we describe the epileptic manifestations in six out of 55 SLE patients. Seizures were the SLE onset symptom for three patients, appeared during the active disease in two cases, and occurred during a period of clinical remission in one patient. In all cases we documented the association of epilepsy with the MTHFR mutation: the homozygosity form was present in one case (16.7%), and heterozygosity in five cases (83.3%). Nevertheless, levels of homocysteine in plasma were in the normal range. Moreover, we found a decrease in the level of S protein values in one case, a high titre positivity of anticardiolipin antibodies (aCL) (IgG and IgM) in three patients and low titre positivity (IgG) in one patient, and lupus anticoagulant (LAC) positivity in four cases. In conclusion, we believe that the abnormalities of coagulation present in our patients could be related to epileptogenesis or to an alteration of the seizure threshold.

We present a case of thrombotic thrombocytopenic purpura (TTP) in a human immunodeficiency virus (HIV)-positive woman with altered mental status. Altered mental status with thrombocytopenia may be due to many causes, including consumptive coagulopathy, systemic lupus erythematosis, infection, and as side effects of commonly used anti-seizure medications. Of these, platelet transfusion is ineffective or specifically contraindicated in the consumptive coagulopathies, including TTP. TTP should be considered in all patients with altered mental status or neurologic dysfunction, thrombocytopenia, and hemolytic anemia to prevent morbidity and mortality.
