Systemic lupus erythematosus (SLE) has numerous manifestations. Haematology is the common system influenced by the disease. The antibody antiphospholipid syndrome, secondary hematology disorder in SLE, is related to high incidence of thrombosis. The thrombosis events like myocardial infarction and stroke are high in mortality. We reported a-36-year old woman treated for lung tuberculosis (TB) with secondary infection, nephritis lupus, and pancytopenia. The general condition has improved and the patient was planned to discharge while she suddenly fell down, unconscious and had seizure. The CT-scan showed an area of hypodensity on the left thalamus. Haematology results showed high level of fibrinogen and D-dimer as the signs of thrombosis. The anticardiolipin antibody was intermediately positive for IgG and IgM, but lupus anticoagulan was weakly positive. The serial test within 2 months still showed positive IgG. The patient received supportive treatment, heparinization, neurotropic drugs and anticonvulsant. She was discharged in good condition while continuing oral anticoagulant to prevent recurrent seizure.

In this retrospective study, we reviewed the charts and collected clinical and radiographic data on children (age range, 1 month to 18 years) with symptoms and radiographic confirmation of ischemic stroke for the period of January 1996 to July 2006. Ninety-four children were enrolled. Eighty-eight had arterial ischemic stroke and six had sinovenous thrombosis. Twenty-nine percent of the children had seizures. Twenty-six percent had diffuse neurological signs and 76% had focal neurological signs. Risk factors included vascular disease (33%), infection (27%), metabolic disorders (18%), trauma (11%), prothrombotic states (13%), cardiac disease (10%), and mitochondrial disease (6%). Ten percent (n=9) had no identifiable cause. Twenty-two percent of the children had more than one risk factor. Anterior territory (70%) was more involved than posterior territory (18%) in arterial ischemic stroke. Unilateral infarctions were more common on the left side (51%) than on the right (24.5%). Neurological deficits were present in 45% (n=34/75) of the children; the most frequent deficit was motor impairment (24%). Seven children (9%) died in the acute stage. There were 12 children (16%) who had recurrent stroke and 8 children (8/12) who had underlying vascular disease. The vascular disease included moyamoya disease (5), CNS lupus (1) and ill-defined vasculopathy (2). The etiology pattern in Taiwan was different from that in Western countries. Vascular disease was a significant risk factor for recurrence in childhood ischemic stroke.

Neuropsychiatric systemic lupus erythematosus (NPSLE) has become a popular term designing all neurological and psychiatric complications in patients with systemic lupus erythematosus (SLE). It occurs in up to two thirds of all SLE patients and it covers a vast array of disorders ranging from peripheral neuropathy to stroke, psychosis, and dementia. Mechanisms associated with the pathogenesis of NPSLE include anti-neuronal antibodies, antiphospholipid antibody associated thrombosis, emboli from cardiac source and, rarely, vasculitis by immune complex depositions. Although the most common manifestations is cognitive dysfunction (50%), NPSLE may also present itself as peripheral neuropathy (15%), psychosis (10%), or other central nervous system abnormalities (stroke, organic brain syndrome, seizures). In lupus patients, one should always look for secondary causes of the neuropsychiatric manifestation, including infection, toxic metabolic abnormalities, and hypertension. We present two cases of SLE, which developed neuropsychiatric manifestations.

Previous reports suggest a protective role for anti-La autoantibody against the development of lupus nephritis. We studied the effect of anti-La on the prevalence of nephritis in a large cohort of lupus patients. In addition, we determined the association between anti-La and the presence of the various other lupus manifestations. We studied 1100 lupus patients enrolled in the Lupus Family Registry and Repository. Only one lupus patient per family was selected to exclude intrafamilial correlation. Since anti-La is present in patients who also have anti-Ro autoantibody, we compared anti-Ro positive lupus patients in the presence or absence of anti-La. Clinical data were obtained from medical records, interviews and participant questionnaires. Tests for autoantibodies against extractable nuclear antigens were performed using immunodiffussion assays. There is no difference in the age, sex or race between the anti-La positive and anti-La negative lupus patients. The presence of anti-La is associated with a significant reduced risk of lupus nephritis (proteinuria: 29.3% versus 46.3%, OR = 0.48, P = 0.023; cellular casts: 8.6% versus 20.6%, OR = 0.36, P = 0.038). In addition, lupus patients with anti-La have a reduced risk for seizures (0% versus 10.9%, P = 0.0096) and are more likely to have arthritis (79.3% versus 64.0%, OR = 2.16, P = 0.031). The presence of anti-nRNP autoantibody is significantly reduced in anti-La positive compared with anti-La negative lupus patients (10.3% versus 27.4%, OR = 0.31, P = 0.0075). In conclusion, anti-La autoantibody is associated with less severe lupus. Patients with anti-La have a lower risk of renal involvement and seizures compared with anti-La negative lupus patients.

Reversible posterior leucoencephalopathy syndrome (RPLS) has been increasingly recognized and reported in the literature. While the condition has been well described in patients with acute hypertension, pre-eclampsia, eclampsia, post-transplantation and chemotherapy, RPLS has been increasingly identified in patients with autoimmune diseases such as systemic lupus erythematosus (SLE). Though experience in the diagnosis and management of RPLS in patients with SLE is likely accumulating, few have systematically worked out the strategy to distinguish RPLS from neuropsychiatric SLE (NPSLE) and lupus-related complications of the central nervous system (CNS). Prompt recognition of, and differentiation between, these conditions is essential since their clinical presentations substantially overlap and yet their management strategy and subsequent outcomes can be entirely different. Indeed, inappropriate treatment such as augmentation of immunosuppression may be detrimental to patients with RPLS. A high index of suspicion of RPLS, prompt magnetic resonance imaging of the brain, including diffusion imaging, exclusion of CNS infection and metabolic derangement, a comprehensive medication review accompanied by timely and aggressive control of blood pressure and seizure are keys to successful management of RPLS. Such treatment strategy ensures a very high chance of total neurological recovery in lupus patients with RPLS.

Neuropsychiatric (NP) events are severe manifestations of systemic lupus erythematosus (SLE) and relate to poor outcome. The aims of this study are to investigate the NP manifestations of SLE and to identify the predictive factors for clinical outcome. There was a retrospective review of 240 hospital patients with primary NP events of SLE (NPSLE) from 1990 to 2004. Neuropsychiatric manifestations, SLE disease activity index (SLEDAI) score, System lupus International Collaborating Clinic/American College of Rheumatology Damage Index (SLICC/ACR-DI) score, magnetic resonance imaging (MRI) findings, treatment and mortality rate were included for analysis. From this group of patients, 15 NP syndromes were identified. The most frequent manifestation was headache, followed by seizure. The mean SLEDAI and SLICC/ACR-DI scores were 19.9 +/- 6.9 and 3.5 +/- 1.6, respectively. Abnormal MRI features were found in 67% (61/91) patients. At least one intrathecal (IT) injection of methotrexate (MTX) plus dexamethasone (DXM) was administered to 109 (45.4%) patients. High dose (1 g) intravenous methylprednisolone pulse therapy (IVMP) was administered to 167 (69.5%) patients. Multifactor analysis revealed that high SLICC/ACR-DI scores and sets of concurrent NP symptoms were independently associated with poor outcome, whereas pulse IVMP and IT injection of MTX plus DXM were protective factors against poor outcome. From our data, NPSLE is heterogeneous and is usually associated with high disease activity and organ damage scores. High SLICC/ACR-DI score and having more than two sets of NP symptoms are the predictors for poor outcome, whereas pulse IVMP and IT injection of MTX plus DXM can improve the prognosis.

Systemic lupus erythematosus is a chronic autoimmune disease that can be associated with a variety of haematological manifestations. We identified 76 patients with haemolytic anaemia in a cohort of 1251 unrelated female lupus patients enrolled in our studies. The presence of the various American College of Rheumatology clinical criteria for lupus and serological specificities were determined in lupus patients with haemolytic anaemia and compared with a group of race-matched control lupus patients without haemolytic anaemia. Clinical data were obtained from medical records, and serological specificities were determined in our clinical immunology laboratory at OMRF. The presence of haemolytic anaemia in lupus patients was associated with a higher frequency of proteinuria (OR = 2.70, P = 0.000031), urinary cellular casts (OR = 2.83, P = 0.000062), seizures (OR = 2.96, P = 0.00024), pericarditis (OR = 2.21, P = 0.0019), pleuritis (OR = 1.72, P = 0.028) and lymphopenia (OR = 1.79, P = 0.015). These findings were independent of the presence of thrombocytopenia, which was approximately five times more common in lupus patients with haemolytic anaemia. Lupus patients with haemolytic anaemia were about 8 years younger than lupus patients without haemolytic anaemia at the time of disease onset (P = 0.000001). In the absence of thrombocytopenia, lupus patients with haemolytic anaemia were approximately two times more likely to have anti-dsDNA antibodies (P = 0.024). The presence of haemolytic anaemia is associated with a subset of lupus characterized by a younger age of disease onset, and a more severe disease with a higher likelihood of renal involvement, seizures, serositis and other cytopenias.

Neuropsychiatric symptoms are recognized to occur in a significant percentage of systemic lupus erythematosus patients and to be a leading cause of morbidity and mortality in lupus. The aim of the present study is to investigate neuropsychiatric symptoms in the patients with lupus nephritis without chronic renal failure. We studied 74 patients (4 male, 70 female) with SLE without chronic renal failure. Disease activity was assessed by the European Consensus Lupus activity Measurement (ECLAM). Renal biopsies disclosed type V lesions in 23 patients, type IV--in 34, type III--in 3, type II--in 11, type I--in 3 patients. Two control groups are used--with rheumatoid arthritis (96 patients) and 63 healthy subjects. The most frequent clinical manifestations are cognitive dysfunction (52.94%), headache (29.41%), psychoses (17.65%), epileptic seizures (20.59%) etc., and the most common cognitive deficit is related to impairment of the memory. The tests for cognitive disorders and nuclear magnetic resonance are the methods of investigation, by which the nervous system injuries are most early detected in the course of the disease. The presented study describes the correlations between the immunologic deviations (antiribosomal P-antibodies, aPL, aSm, aC1q), MMP-9, AT III and the NP injuries.

We present a case of a 20-year-old woman admitted with new onset severe systemic lupus erythematosus (SLE) with multiple manifestations, including lupus nephritis with renal failure and significant central nervous system (CNS) lupus. She presented with a forbidding condition and deteriorated despite a regimen of high dose corticosteroids and cyclophosphamide administration. She had progressive CNS disease initially, with multiple generalized tonic-clonic seizures and later with dense left sided hemiparesis. After treatment with high dose intravenous immunoglobulin (IVIG), there was remarkable improvement in overall lupus disease activity and resolution of neurologic deficits. A head magnetic resonance imaging (MRI) scan early in her hospital course revealed multiple areas of vasogenic and cortical edema consistent with ischemic changes, possibly from lupus vasculitis. A repeat MRI after IVIG treatment revealed dramatic interval improvement and resolution of most of the multifocal areas of signal abnormality.The use of IVIG has been reported in a variety of autoimmune disorders, and there have also been several case reports of the successful use of IVIG in the treatment of SLE. IVIG seems to be a relatively safe treatment alternative and may have a promising role in the future of lupus treatment. We have found only five case reports in the literature specifically involving the use of IVIG in CNS lupus, but they show substantial benefits. Our case is unique because the demonstration of dramatic response to IVIG by a head MRI has not previously been reported. Based on the available information and the observations in this case, IVIG remains an experimental but promising treatment option for patients with SLE.

In this study, we aimed to analyze features and outcome of convulsion in pediatric lupus nephritis patients. We retrospectively reviewed data of 14 Iranian children with lupus nephritis who developed seizures and compared them with a group of the same number of well matched pediatric lupus nephritis patients. Higher serum creatinine levels and higher frequencies of anemia and lymphopenia were observed in the convulsion group. Multivariable logistic regression analysis revealed that the only risk factor for development of convulsion in pediatric lupus patients with nephritis was lymphopenia. Survival analysis showed that convulsion had no impact on patient and renal function outcomes in our pediatric lupus nephritis subjects. In conclusion, we found that lymphopenia is a predictive factor for convulsion occurrence in our patients and special attention to neurological status assessment may be needed in this situation.
