Abstract
Systemic lupus erythematosus (SLE) and multiple sclerosis (MS) are chronic immunologic diseases that can cause cognitive dysfunction. MS is a central nervous system (CNS) disease characterized by demyelination and progressive brain atrophy. SLE is an autoimmune disease capable of damaging multiple organ systems, including the CNS. Cognitive disturbances are seen in both SLE and MS. The present study is concerned with understanding the similarities and differences between the cognitive profiles of SLE and MS as well as the relationship between cognitive impairment and vocational disability in these patients. We examined 47 SLE patients, 47 MS patients, and 44 healthy controls. The groups were well matched on demographics and the patient groups were also matched on disease duration and severity. Group comparisons revealed that generative verbal fluency and visual-spatial memory are more profoundly affected in MS than SLE; whereas depression, fatigue, and working memory deficits are similarly involved in both diseases. Logistic regression analysis revealed that executive function, in particular, was predictive of vocational outcomes in SLE and MS patients.

Abstract
Although involvement of the reticuloendothelial system in systemic lupus erythematosus (SLE) is a well-recognised concomitant of the disease, spontaneous splenic rupture is an unusual occurrence. We observed a 54-year-old woman with SLE who had spontaneous splenic rupture during the late course of the disease and showed some changes histopathologically. The courses and the clinical characteristics of such patients are reviewed, and the diagnosis and treatment of these cases are discussed. Early evaluation for SLE patients with spontaneous splenic rupture should be considered and included in the differential diagnosis of acute abdomen, as it may affect follow-up and treatment, although the condition is rare.

Abstract
Systemic lupus erythematosus (SLE) is a relapsing-remitting autoimmune disease with CNS involvement occurring in up to 75% of patients. However, the frequency of neuropsychiatric manifestations in SLE studies varies widely, depending on the type of manifestations included and the method used for evaluation. CNS involvement may be considered primary if directly related to SLE activity in the CNS or secondary when related to treatment, infections, metabolic abnormalities or other systemic manifestations such as uraemia and hypertension. The pathogenesis of neuropsychiatric SLE is as yet unknown, though numerous autoantibodies and cytokines have been suggested as possible mediators. However, independent of the aetiology of the insult, the final common pathway in neuropsychiatric SLE is the involvement of the cerebral microvasculature. The diagnosis of primary CNS involvement by SLE is often difficult, as both focal and diffuse manifestations may occur and there is no gold standard for diagnosis. A high index of clinical suspicion, in addition to laboratory and neuroimaging findings may support the diagnosis. Treatment is mostly empirical, although one randomized controlled trial has shown that cyclophosphamide in addition to methylprednisolone is superior to methylprednisolone alone in severe neuropsychiatric SLE.

Abstract
Gastrointestinal (GI) symptoms are common in patients with systemic lupus erythematosus (SLE) and may be due to the disease itself, side-effects of medications, or non-SLE causes. However, GI manifestations of lupus attract far less attention than the other major organ involvements, are infrequently reviewed and rarely documented in published lupus databases or cohort studies including those from countries in Asia. According to three reports from two countries in Asia, the cumulative prevalence of SLE GI manifestations range from 3.8% to 18%. In this review, we focus on three major GI manifestations in patients from Asian countries: lupus enteritis, intestinal pseudo-obstruction, and protein-losing gastroenteropathy, for which early recognition improves outcome and reduces morbidity and mortality.

Abstract
PURPOSE To use perfusion weighted MR to quantify any perfusion abnormalities and to determine their contribution to neuropsychiatric (NP) involvement in systemic lupus erythematosus (SLE). MATERIALS AND METHODS We applied dynamic susceptibility contrast (DSC) perfusion MRI in 15 active NPSLE, 26 inactive NPSLE patients, and 11 control subjects. Cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) maps were reconstructed and regions of interest were compared between groups. In addition, the effect of SLE criteria, NPSLE syndromes, immunological coagulation disorder, and medication on CBF, CBV, and MTT was investigated. RESULTS No significant differences were found between the groups in CBF, CBV, and MTT. No significant influence of SLE criteria or NPSLE syndromes on CBF, CBV, or MTT was found. No significant influence of anti-cardiolipin antibodies, lupus anti-coagulant, the presence of anti-phospholipid syndrome (APS), or medication on CBF, CBV, or MTT was found. CONCLUSION Our findings suggest CBF, CBV, and MTT in the white and the gray matter in SLE patients is not significantly different from healthy controls or between patients with and without specific symptoms or with and without immunological disorder involving coagulation.

Abstract
The catastrophic antiphospholipid syndrome (APS) is a potentially life-threatening condition, the diagnosis of which requires a high degree of clinical awareness on the part of attending physicians. Patients with APS present with 1) clinical evidence of multiple organ involvement developed over a very short time; 2) histopathologic evidence of multiple small-vessel occlusions; and 3) laboratory confirmation of the presence of antiphospholipid antibodies, usually in high titer. A combination of anticoagulants, corticosteroids, intravenous immunoglobulins, and plasma exchanges is the basic treatment for all patients with this severe condition. Unfortunately, despite current therapies, the mortality rate is still high (around 30%). However, once patients with catastrophic APS have recovered, they usually follow a stable course with continued anticoagulation and few patients present with a relapse of the catastrophic episode.

Abstract
OBJECTIVE To determine the histopathologic basis of altered brain neurometabolites in neuropsychiatric systemic lupus erythematosus (NPSLE). METHODS Brain neurometabolite concentrations in a 20-voxel area of the brain were determined premortem by magnetic resonance spectroscopy (MRS) in 7 individuals with NPSLE. Absolute concentrations of neurometabolite for N-acetylaspartate (NAA), choline, creatine, and lactate were measured. After the death of the patients, histopathologic changes were determined at autopsy of the brain and were matched voxel-by-voxel with the neurometabolites. RESULTS The mean +/- SD absolute concentrations of NAA (9.15 +/- 1.78 mM in patients versus 12.2 +/- 0.8 mM in controls; P < 0.01) and creatine (6.43 +/- 0.16 mM in patients versus 6.90 +/- 0.60 mM in controls; P < 0.003) were significantly reduced and the concentration of choline (2.51 +/- 0.42 mM in patients versus 1.92 +/- 0.32 mM in controls; P < 0.04) was significantly elevated in NPSLE patients as compared with controls. Widespread heterogeneous changes in the histologic features of the brain were present, including microinfarcts, microhemorrhages, bland angiopathy, thrombotic angiopathy with platelet and fibrin thrombi, neuronal necrosis in various states of resolution, reduced numbers of axons and neurons, vacuole and space formation among the fibers, reduced numbers of oligodendrocytes, reactive microglia and astrocytes, lipid-laden macrophages, and cyst formation. Neurometabolite abnormalities were closely associated with underlying histopathologic changes in the brain: 1) elevated choline levels were independently associated with gliosis, vasculopathy, and edema (r = 0.75, P < 0.004 in the multivariate model); 2) reduced creatine levels with reduced neuronal-axonal density and gliosis (r = 0.72, P < 0.002 in the multivariate model); 3) reduced NAA levels with reduced neuronal-axonal density (r = 0.66, P < 0.001 in the multivariate model); and 4) the presence of lactate with necrosis, microhemorrhages, and edema (r = 0.996, P < 0.0001 in the multivariate model). CONCLUSION Altered neurometabolites in NPSLE patients, as determined by MRS, are a grave prognostic sign, indicating serious underlying histologic brain injury.

Abstract
Systemic lupus erythematosus (SLE) is a highly variable autoimmune disease characterized by aberrant host-immune responses and chronic inflammation. Recently, a strong association between cardiovascular (CV) disease and SLE has emerged. Thus, low serum, high-density lipoprotein strongly correlated with elevated erythrocyte sedimentation rate, IL-6, TNF-alpha and the SLE disease activity index after adjusting for age, gender, race, BMI, insulin sensitivity and any concurrent drug use. In SLE, CV disease is characterized by increased VEGF, which may alter vascular hemostasis and promote neoangiogenesis. Increased low-density lipoprotein-cholesterol and proinflammatory high-density lipoprotein-cholesterol uptake by monocytes together with enhanced low-density lipoprotein-cholesterol oxidation results in the deposition of altered cholesterol forms into the vascular wall. This contributes to precocious and accelerated development of coronary artery plaques. Cholesterol-reducing drugs should be considered in the standard of care of SLE patients, especially in those with an unfavorable CV disease risk profile, which could reduce the probability of atherosclerosis progressing to CV disease or stroke in these patients.

Abstract
The aim of the study was to evaluate the correlation between selected serum endothelial cell activation markers such as vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), soluble thrombomodulin (sTM), soluble E-selectin (sE-selectin), disease activity, and microvascular changes determined by nailfold capillaroscopy in patients with systemic lupus erythematosus (SLE). Serum levels of VEGF, ET-1, sTM, and sE-selectin were determined by an enzyme-linked immunosorbent assay in 80 SLE patients. The disease activity was measured with Systemic Lupus Erythematosus Disease Activity Index score. Nailfold capillaroscopy was performed in all patients. Positive correlation was found between VEGF and both ET-1 (r = 0.294, p < 0.01) and sE-selectin (r = 0.274, p < 0.05) serum levels as well as between sTM and ET-1 (r = 0.273, p < 0.05) serum concentrations. We noticed also positive correlation between VEGF (r = 0.224, p < 0.05) and ET-1 (r = 0.471, p < 0.001) serum levels and disease activity, and also between VEGF serum concentration and grade of morphological changes observed by nailfold capillaroscopy (r = 0.458, p < 0.001). There was also positive correlation between capillaroscopic score and disease activity (r = 0.339, p < 0.01). Our data suggest that correlation between VEGF and both ET-1 and E-selectin serum levels as well as between sTM and ET-1 serum concentrations may reflect their participation in the pathogenesis of SLE. VEGF seems to reflect changes in microcirculation in the course of SLE, visualised by nailfold capillaroscopy. The relationship between changes in nailfold capillaroscopy, endothelial cell activation markers, and the clinical activity of SLE points to an important role of microvascular abnormalities in the clinical manifestation of the disease.

Abstract
OBJECTIVE Magnetic resonance imaging (MRI) often demonstrates brain lesions in neuropsychiatric systemic lupus erythematosus (NPSLE). The present study compared postmortem histopathology with premortem MRI in NPSLE. METHODS Two hundred subjects with NPSLE were studied prospectively with MRI over a 10-year period during which 22 subjects died. In 14 subjects, a brain autopsy with histopathology, that permitted direct comparison with premortem MRI, was successfully obtained. Surface anatomy was used to determine the approximate location of individual lesions. RESULTS Premortem MRI findings in fatal NPSLE were small focal white matter lesions (100%), cortical atrophy (64%), ventricular dilation (57%), cerebral edema (50%), diffuse white matter abnormalities (43%), focal atrophy (36%), cerebral infarction (29%), acute leukoencephalopathy (25%), intracranial hemorrhage (21%), and calcifications (7%). Microscopic findings in fatal NPSLE included global ischemic changes (57%), parenchymal edema (50%), microhemorrhages (43%), glial hyperplasia (43%), diffuse neuronal/axonal loss (36%), resolved cerebral infarction (33%), microthomboemboli (29%), blood vessel remodeling (29%), acute cerebral infarction (14%), acute macrohemorrhages (14%), and resolved intracranial hemorrhages (7%). Cortical atrophy and ventricular dilation seen by MRI accurately predicted brain mass at autopsy (r = -0.72, P = 0.01, and r = -0.77, P = 0.01, respectively). Cerebral autopsy findings, including infarction, cerebral edema, intracranial hemorrhage, calcifications, cysts, and focal atrophy, were also predicted accurately by premortem MRI. CONCLUSION Brain lesions in NPSLE detected by MRI accurately represent serious underlying cerebrovascular and parenchymal brain injury on pathology.

Abstract
In kidneys from patients with lupus nephritis, Avihingsanon et al. report that decreased renal expression of vascular endothelial growth factor (VEGF) may be a protective mechanism against renal damage and a predictive factor for loss of kidney function. This finding could be an important tool for understanding the role of VEGF in renal disease and for the early detection of lupus nephritis, as the long-term prognosis still remains poor despite improvement in medium-term survival of patients.

Abstract
Vasculitis can occur either as a primary condition or secondary to CTDs, infection, medication or malignancy. This article reviews the clinical presentation and management of vascular disease associated with SLE and SS, as well as the primary necrotizing vasculitides. Although pulmonary arterial hypertension (PAH) has traditionally been considered a rare complication of SLE, estimates of its prevalence range from 0.5% to 14% and it has a significant impact on prognosis. In contrast to PAH associated with other CTDs, patients with SLE respond well to immunosuppressive agents (cyclophosphamide in conjunction with corticosteroids). Improvements or stabilization of PAH symptoms and quality of life have also been observed with the oral, dual endothelin receptor antagonist, bosentan. SS is associated with a range of cutaneous and systemic signs of vasculitis. Immunosuppressive agents are effective, but are associated with an increased risk of lymphoma. The necrotizing vasculitides include WG, Churg-Strauss syndrome and microscopic polyangiitis, and are characterized by autoantibodies to neutrophil cytoplasmic constituents. WG is one of the most common forms of vasculitis; patients usually present with signs of respiratory disease. All three necrotizing vasculitides respond to cyclophosphamide and corticosteroids, while the less toxic AZA and MTX are effective for maintenance therapy. Future therapeutic approaches may include rituximab, plasma exchanges, the TNF antagonist infliximab and haematopoietic stem cell transplantation.

Abstract
Systemic lupus erythematosus (SLE) has diverse imaging features. However, focal lesions in the corpus callosum are extremely rare in SLE with only few cases mentioned in the literature, with no mention of callosal holes in SLE. Callosal holes have been described as a characteristic finding in Susac syndrome and have been mentioned in Nipah virus encephalitis, Marchiafava Bignami disease and periventricular leukomalacia. We describe a case of SLE with callosal holes. The demonstration of callosal holes in this case brings the imaging appearance of SLE a step closer to that of Susac syndrome which is considered a clinically and radiologically close condition. It also adds to the list of imaging appearances of central nervous system SLE.

Abstract
The complement cascade has long been recognized to play a key role in inflammatory and degenerative diseases. It is a 'double edged' sword as it is necessary to maintain health, yet can have adverse effects when unregulated, often exacerbating disease. The contrasting effects of complement, depending on whether in a setting of health or disease, is the price paid to achieve flexibility in scope and degree of a protective response for the host from infection and injury. Loss or even decreased efficiency of critical regulatory control mechanisms can result in aggravated inflammation and destruction of self-tissue. The role of the complement cascade is poorly understood in the nervous system and neurological disorders. Novel studies have demonstrated that the expression of complement proteins in brain varies in different cell types and the effects of complement activation in various disease settings appear to differ. Understanding the functioning of this cascade is essential, as it has therapeutic implications. In this review, we will attempt to provide insight into how this complex cascade functions and to identify potential strategic targets for therapeutic intervention in chronic diseases as well as acute injury in the CNS.

Abstract
We studied the expression of reversion-inducing cysteine-rich protein with Kazal motifs (RECK) on peripheral blood mononuclear cells (PBMCs), the serum concentration of matrix metalloproteinase 9 (MMP-9) and the MMP-9 secretion ability of PBMCs in patients with systemic lupus erythematosus (SLE), and clinical features were assessed. Compared with PBMCs from healthy donors, PBMCs from SLE patients expressed less RECK protein and mRNA but secreted more MMP-9. The serum concentration of MMP-9 was, however, lower in SLE patients than in healthy donors. The level of RECK protein was inversely associated with the Systemic Lupus International Collaborating Clinics (SLICC) Damage Index (SDI) and MMP-9 secretion in SLE, but no relationship was found between serum MMP-9 concentration and the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). In conclusion, the level of RECK protein expressed in PBMCs could be used to predict organ or system damage in SLE and this might help in developing new therapies for SLE targeted at MMP-9.

Abstract
Cases of mesenteric vasculitis in systemic lupus erythematosus (SLE) are well described, however, individual patient with recurrent mesenteric vasculopathy producing repeated episodes with each exacerbation similar in character and quality has not been reported previously in the literature. We describe two SLE patients whose condition was complicated by repeated stereotypic, CT confirmed, episodes of lupus enteritis characterized by dramatic intestinal wall edema. Moreover, each flare was accompanied by significant hypocomplementemia and was rapidly reversible suggesting an acute gastrointestinal distress syndrome (AGDS) as a result of leukoaggregation and a gut capillary leak syndrome.

Abstract
INTRODUCTION The aim of the study was to evaluate whether vascular endothelial growth factor (VEGF) serum level is associated with systemic organ involvement, microvascular changes as determined by nailfold capillaroscopy, and disease activity of systemic lupus erythematosus (SLE). MATERIALS AND METHODS Serum levels of VEGF were determined by an enzyme-linked immunosorbent assay in 47 SLE patients and in 30 healthy controls. Nailfold capillaroscopy was performed in all patients and healthy subjects. RESULTS Morphological changes were observed by nailfold capillaroscopy in 45 of 47 (95.7%) SLE patients. Mild capillary changes were found in 16 (34%), moderate in 21 (44.7%), and severe in 8 (17%) SLE patients. All patients with systemic organ involvement showed severe or moderate changes in nailfold capillaroscopy. In comparison with the control group, a higher serum concentration of VEGF in SLE patients was demonstrated (p<0.05). Furthermore, significant differences in VEGF serum concentration between SLE patients with systemic involvement and controls were found (p<0.01). Comparison between patients with active and inactive SLE according to SLEDAI score showed a significantly higher concentration of VEGF in the sera of patients with active SLE (p<0.01). The SLE patients with severe and moderate changes in nailfold capillaroscopy showed significantly higher VEGF serum levels than SLE patients with mild changes (p<0.05) or healthy controls (p<0.01). Moreover, the VEGF serum level correlated significantly with ESR (r=0.580, p<0.0001) and CRP (r=0.512, p<0.005). CONCLUSIONS Our data suggest that VEGF serum level may be a useful marker of disease activity and internal organ involvement in SLE patients. Abnormalities in nailfold capillaroscopy may reflect the extent of microvascular involvement and are associated with systemic manifestation in SLE.

Abstract
We are reporting a case of catastrophic antiphospholipid syndrome (CAPS) in an adult female manifested with severe hypertension followed by adrenal haemorrhagic infarction and adult respiratory distress syndrome. Adrenal involvement appears to be exceedingly high in CAPS and adult respiratory distress syndrome (ARDS) is the prevailing pulmonary manifestation in this condition, compared with these impediments in patients with simple antiphospholipid syndrome (APS). Even though the above manifestations are well recognized, their combination as an initial presentation of CAPS is uncommon.

Abstract
We investigated the serum concentration of total metalloproteinase-9 (tMPP-9), active MMP-9 (aMMP-9), and tissue inhibitor of metalloproteinase-1 (TIMP-1) in a group of 41 patients with SLE and 20 healthy controls. Serum levels of tMMP-9 and TIMP-1 were assessed by an enzyme-linked immunosorbent assay (ELISA) and aMMP-9 by fluorometric assay. The tMMP-9 level was lower in SLE patients (mean 262 ng/mL) than in healthy volunteers (mean 325 ng/mL) (P = .048). Similarly, aMMP-9 level was lower in SLE patients (mean 121 ng/mL) than in control group (mean 169 ng/mL) (P = .0355) and lower in active SLE (mean 54 ng/mL) than in inactive disease (mean 99 ng/mL) (P = .033). TIMP-1 level was also lower in SLE patients (mean 181 ng/mL) than in control group (mean 233 ng/mL) (P = .004). In SLE patients, a positive correlation was found between tMMP-9 and aMMP-9 (rho = 0.568; P = .001). We also found a positive correlation of tMMP-9 and TIMP-1 with VEGF concentrations (rho = 0.450, P = .005 and rho = 0.387; P = .018, resp). tMMP-9, aMMP-9, and TIMP-1 serum levels are lower in SLE patients than in healthy control group.

Abstract
A broad and diverse spectrum of vasculitic syndromes exists. These syndromes affect the skin with varying levels of associated systemic manifestations, running the gamut from a self-limited, localized, cutaneous phenomenon to rapidly progressive, multiorgan disease. The majority of cases of cutaneous vasculitis will show a neutrophilic small vessel vasculitis that can be either a primary (idiopathic) disorder (eg, cutaneous leukocytoclastic angiitis) or a secondary disorder that is associated with drugs, infection (eg, streptococcal infection, viral hepatitis), or underlying disease (eg, connective tissue disease, malignancy). Biopsy is the gold standard for the diagnosis of cutaneous vasculitis and also necessary for the detection of cutaneous vascular immune complexes by direct immunofluorescence. Based on the type of vessel disrupted by inflammation (small and/or muscular), the distribution of vasculitis in the dermis and subcutis, and predominate inflammatory cell-type mediating vessel wall damage, a list of relevant differential diagnoses can be generated. This histologic information coupled with extravascular findings such as tissue eosinophilia, tissue neutrophilia, and/or granulomas, plus pathophysiologic markers such as direct immunofluorescent examination for immune complexes and serologic evaluation for antineutrophil cytoplasmic antibodies allows for more accurate diagnosis of specific vasculitic entities. Herein, we review both primary and secondary vasculitic syndromes that affect the skin and show a small vessel neutrophilic mediated vasculitis.

Abstract
Catastrophic APS is a potentially life-threatening condition with a high mortality, which requires high clinical awareness. New mechanisms for its production can only be explored if samples are obtained, stored, and dis-patched to investigation sites in Europe (Barcelona), the United States (Atlanta), and Japan (Sapporo). Details will be posted and made available on the International Registry Web Site in 2006. It is essential that the condition be diagnosed early and treated aggressively. The combination of high doses of iv heparin, iv steroids plus repeated doses of iv gammaglobulins or plasma exchange is the treatment of choice in patients with this severe condition. Additionally, preventive measures in patients with APS may be effective if the development of the catastrophic APS is to be avoided.

Abstract
To understand the clinical significance and mechanisms of cutaneous denervation in systemic lupus erythematosus (SLE), we assessed intraepidermal nerve fibre (IENF) density of the distal leg in 45 SLE patients (4 males and 41 females, aged 38.4 +/- 13.6 years) and analysed its correlations with pathology, lupus activity, sensory thresholds and electrophysiological parameters. Compared with age- and gender-matched control subjects, SLE patients had lower IENF densities (3.08 +/- 2.17 versus 11.27 +/- 3.96 fibres/mm, P < 0.0001); IENF densities were reduced in 38 patients (82.2%). Pathologically, 11 patients (24.4%) were found to have definite cutaneous vasculitis; the severity and extent of cutaneous vasculitis were correlated with IENF densities. Patients with active lupus had even lower IENF densities than those with quiescent lupus (1.86 +/- 1.37 versus 4.15 +/- 2.20 fibres/mm, P = 0.0002). By linear regression analysis, IENF densities were negatively correlated with the SLE disease activity index (r = 0.527, P = 0.0002) and cumulative episodes of lupus flare-up within 2 years before the skin biopsy (r = 0.616, P = 0.0014). Clinically, skin denervation was present not only in the patients with sensory neuropathy but also in the patients with neuropsychiatric syndrome involving the CNS. SLE patients had significantly elevated warm threshold temperatures (P = 0.003) and reduced cold threshold temperatures (P = 0.048); elevated warm threshold temperatures were associated with the reduced IENF densities (P = 0.032). In conclusion, cutaneous vasculitis and lupus activities underlie skin denervation with associated elevation of thermal thresholds as a major manifestation of sensory nerve injury in SLE.

Abstract
BACKGROUND The acute respiratory distress syndrome (ARDS) is a non-cardiogenic form of pulmonary oedema characterised by severe hypoxaemia refractory to oxygen therapy, with diffuse pulmonary infiltrates on chest radiographs. It can be precipitated by various serious medical and surgical conditions, including systemic autoimmune diseases. The "catastrophic" variant of the antiphospholipid syndrome (APS) is an accelerated form of this systemic autoimmune condition which results in multiorgan failure because of multiple small vessel occlusions. OBJECTIVE To analyse the clinical and laboratory characteristics of patients with catastrophic APS who develop ARDS. METHODS Cases with ARDS were selected from the web site based international registry of patients with catastrophic APS (CAPS registry) (http://www.med.ub.es/MIMMUN/FORUM/CAPS.HTM) and their characteristics examined. RESULTS Pulmonary involvement was reported in 150 of 220 patients with catastrophic APS (68%) and 47 patients (21%) were diagnosed as having ARDS. Nineteen (40%) of these patients died. Pathological studies were undertaken in 10 patients and thrombotic microangiopathy was present in seven. There were no differences in age, sex, precipitating factors, clinical manifestations, or mortality between catastrophic APS patients with and without ARDS. CONCLUSIONS ARDS is the dominant pulmonary manifestation of catastrophic APS. Thus the existence of ARDS in the context of an APS makes it necessary to rule out the presence of the catastrophic variant of this syndrome.

Abstract
Numerous connective tissue diseases, such as systemic lupus erythematosus (SLE), and infectious states, such as leprosy, are characterized by early vascular endothelial cell (EC) damage. There is substantial interest in the role of anti-EC antibodies (AECA) in such an injury. Due to the diversity of AECA-associated conditions, these autoantibodies are likely to be heterogeneous, and, therefore, identification of their antigens (Ag) to be difficult. They may be classified into three groups: membrane components, ligand-receptor complexes and Ag derived from the blood and attached to the cell surface. New technologies have been developed to sort it out, such as expression libraries and two-dimensional electrophoresis. A handful of Ag have hitherto been recognized viz. heat-shock protein 60 in SLE and leprosy, or plasminogen activator inhibitor-1 in SLE and Wegener granulomatosis. In reality, most of the target Ag for AECA remain to be identified.

Abstract
OBJECTIVE Nailfold capillaroscopy (NFC) has been shown to have a remarkable value in the differential diagnosis of connective tissue diseases. In fact, NFC patterns reflect the microvascular changes that may play a significant role in pathogenesis. The aims of this study were to determine in patients with systemic lupus erythematosus (SLE) the prevalence of NFC patterns, to evaluate any association with clinical features and laboratory parameters. MATERIALS AND METHODS One hundred twenty-three patients with SLE were included in this retrospective study. Video NFC parameters were analyzed in each patient. In all cases, the following parameters were evaluated: capillary arrangement, density, size, and shape. RESULTS In patients with SLE, major capillary abnormalities were frequently observed (44 of 123 = 35.8%); however, no specific pattern was noted. There was a significant correlation between the SLEDAI index and the severity of capillary abnormalities (P < 0.0001). Pathologic capillary abnormalities were also significantly increased in SLE with positive anti-U1-RNP antibodies (P < 0.05). CONCLUSION NFC may be a useful method to evaluate the microvascular changes in patients with SLE, and the presence of major capillary abnormalities seems to herald a more severe clinical course of the illness.

Abstract
OBJECTIVE To investigate the thrombotic tendency in patients with systemic lupus erythematosus (SLE) by evaluating congenital or acquired abnormalities associated with an increased risk of venous and/or arterial thrombosis. METHODS A total of 57 patients with SLE were included in the study. Twenty-one patients (37%) had a history of arterial and/or venous thrombosis and 36 patients (63%) did not have such a history. Sera from 50 healthy controls were examined. Protein C, protein S, antithrombin, D-dimer, fibrinogen, homocysteine, anticardiolipin antibodies (aCL), lupus anticoagulant (LAC), prothrombin G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T gene mutation were evaluated. RESULTS Protein C, antithrombin, fibrinogen, D-dimer, and homocysteine levels were significantly higher in patients with SLE than in controls. A prothrombin mutation was observed in 2 (4%) of 50 controls and in 6 (11%) of 57 patients. A significantly higher prevalence (P = 0.036) of MTHFR homozygous mutation was observed in patients with SLE (14 [25%] of 57) in comparison with controls (4 [8%] of 50). IgG-aCL and IgM-aCL levels were significantly higher in patients with SLE than in controls (P < 0.0001). The presence of medium-high (> or = 20 IgG phospholipid units/ml) IgG-aCL antibody titers was significantly higher (P = 0.005) in patients with thrombosis (11 [52%] of 21) than in patients without (5 [14%] of 36) thrombosis. LAC was present in 22 (38.5%) of 57 patients and in none of 50 controls. CONCLUSION In this study, we confirm the association between thrombosis and IgG-aCL at medium-high titers and suggest that the coexistence of other risk factors can affect the expression of thrombosis in patients with SLE.

Abstract
Monocyte chemoattractant protein-1 (MCP1) polymorphism has been reported to be associated with systemic lupus erythematosus (SLE). However, the correlation between the polymorphism and SLE is poorly understood. In this study we investigated the role of this polymorphism together with that of chemokine SDF1-3'A and chemokine receptor CCR2-V64I. The association between gene polymorphism and SLE was explored by way of a case-control study. In 143 patients with SLE and 157 healthy controls, the polymorphisms of SDF1-3'A, -2518MCP-1 and CCR2-V64I were determined using PCR-RFLP and an amplification-refractory mutation system, respectively. No significant difference was found in allelic and genotype frequency of SDF1-3'A, CCR2-V64I and -2518MCP-1 between SLE patients and controls. However, a significant increase in the frequency of the AG genotype of MCP-1 was found among patients with arthritis (P(c)=0.003, OR 3.08, 95%CI 1.27-7.57). The frequency of individuals having G at position -2518 of the MCP-1 gene was also increased among patients with arthritis (P(c)=0.028, OR 2.99, 95%CI 1.13-8.08). It is noteworthy that the frequency of -2518MCP-1G in the Chinese Han population was 64%. The results indicate an association between the presence of G at position -2518 in the MCP-1 promoter region and the presence of arthritis in patients with SLE.

Abstract
OBJECTIVE To investigate the relationship between magnetization transfer imaging (MTI), diffusion-weighted imaging (DWI), proton magnetic resonance spectroscopy (H-MRS), and T2 relaxometry findings in patients with primary neuropsychiatric systemic lupus erythematosus (NPSLE). METHODS The study group consisted of 24 female patients (mean age 36 years [range 23-65]) who had had a variety of neuropsychiatric symptoms that were judged to be due to NPSLE according to the criteria of the American College of Rheumatology. Patients with current active disease were excluded from participation. Quantitative MTI, DWI, H-MRS, and T2 relaxometry data were acquired in all patients, and the correlation coefficients were calculated. RESULTS MTI results reflecting a decrease in homogeneity of cerebral parenchyma correlated significantly with H-MRS results representing axonal damage. MTI results also correlated significantly with DWI results reflecting increased diffusivity in the cerebral parenchyma. Finally, MTI results reflecting decreased cerebral homogeneity correlated significantly with increased T2 relaxation time, associated with either edema or gliosis. Increased T2 relaxation time correlated significantly with DWI results reflecting increased diffusivity. With the exception of the correlation between H-MRS and MTI findings, there was no significant correlation between H-MRS results and any other parameter. CONCLUSION The selected study parameters represent different biologic features in the human brain and can be informative with regard to different pathologic processes in NPSLE. The demonstrated associations between MTI, DWI, H-MRS, and T2 data in patients with a history of NPSLE suggest that there is one pathogenesis and/or common neuropathologic outcome in NPSLE despite differences in clinical presentation.

Abstract
Vasculitis in connective tissue diseases is not an uncommon complication. Vasculitis complicates both rheumatoid arthritis and systemic lupus erythematosis (SLE) in about 4% of cases. Cutaneous lesions, representing small-vessel involvement, are most common; however, widespread, necrotizing visceral medium-and large-vessel involvement, mimicking primary vasculitic syndromes, may also occur. Connective tissue disease-associated vasculitis is separated from primary vasculitis syndromes in classification schemes. Granulomatous large-vessel disease does not occur in connective tissue diseases, suggesting a different pathogenesis. In most disorders, the etiology of vascular inflammation in not completely understood, but basic pathogenic mechanisms can often be distinguished. The role of immune complexes in the inflammatory manifestations of SLE is recognized, and other pathogenic factors such as antineutrophil cytoplasmic antibodies, common in other vasculitides, are infrequent. A diverse spectrum of clinical features, due to inflammatory involvement of arterial and venous vessels of all sizes, characterize several connective tissue diseases including Behçet's disease and SLE. The recognition of disease manifestations due to vasculitis in these disorders has important implications for treatment and may be critical to reduce morbidity and mortality.

Abstract
PURPOSE OF REVIEW This review deals with new information related to central nervous system lupus, with special emphasis on mechanisms engaged in inflammation and neurodegeneration. RECENT FINDINGS We report the very recent findings related to neuropsychiatric lupus in areas of (1) neuroimaging, (2) immunology and genetics, (3) biochemistry, and (4) neuropsychological tests. The relation between treatment of central nervous system lupus and immunologic/biochemical parameters as an outcome variable is also reported. SUMMARY The recent advances in the field of neuropsychiatric lupus allow better understanding of the pathogenesis of the disease and follow-up of disease activity during immunosuppressive treatment.

Abstract
Nervous system involvement in systemic lupus erythematosus (SLE) is typically diagnosed on the basis of clinical psychiatric and/or neurologic syndromes (NPSLE). Neuropsychological tests can be used to assess nervous system integrity even in the absence of major NP syndromes. Their application has uncovered significant cognitive dysfunction, ranging from mild to severe, in a sizeable proportion of SLE patients irrespective of clinical NP status. Cognitive dysfunction has now been accepted as a bona fide manifestation of NPSLE. The heterogeneity of clinical NPSLE manifestations is paralleled by the diversity of cognitive deficits reported in different studies and within different patients. The success of attempts to explain these deficits on the basis of potential pathogenetic mechanisms, such as antibrain antibodies and proinflammatory cytokines, has been uneven. To date, the most robust findings have emerged in relation to antiphospholipid antibodies, which carry with them important therapeutic implications.

Abstract
Pathogenic mechanisms of central nervous system (CNS) involvement in systemic lupus erythematosus (SLE) remain unknown. We recently reported the presence of autoantibodies in the brain tissue ex vivo of autoimmune MRL/lpr mice. We postulated that at least some of these autoantibodies are produced in situ because of B-cell entry into the brain. The blood-brain barrier (BBB) blocks the entry of most large molecules and cells into the brain. In certain CNS pathologies, however, immune cells gain entry due to elevated expression of adhesion molecules. This study looked at adhesion molecule expression, ICAM-1 and VCAM-1, in the brains of MRL/lpr mice. Using immunofluorescent antibody binding assays and confocal laser imaging, we show that expression of ICAM-1 and VCAM-1 is elevated in MRL/lpr mice brains at 4 months of age as compared to age-matched controls. These results suggest a possible mechanism for leukocyte entry into the brains of autoimmune mice that in turn suggest immune-mediated pathology in CNS-lupus.

Abstract
Our objective was to review the frequency and pattern of signal abnormalities seen on conventional MRI in patients with suspected neuropsychiatric systemic lupus erythematosus (NP-SLE). We reviewed 116 MRI examinations of the brain performed on 85 patients with SLE, (81 women, four men, aged 21-78 years, mean 40.6 years) presenting with neurological disturbances. MRI was normal or nearly normal in 34%. In 60% high-signal lesions were observed on T2-weighted images, frequently in the frontal and parietal subcortical white matter. Infarct-like lesions involving gray and white matter were demonstrated in 21 of cases. Areas of restricted diffusion were seen in 12 of the 67 patients who underwent diffusion-weighted imaging. Other abnormalities included loss of brain volume, hemorrhage, meningeal enhancement, and bilateral high signal in occipital white-matter. The MRI findings alone did not allow us to distinguish between thromboembolic and inflammatory events in many patients. Some patients with normal MRI improved clinically while on immunosuppressive therapy. More sensitive and/or specific imaging methods, such as spectroscopy and perfusion-weighted imaging, should be investigated in these subgroups of patients with suspected NP-SLE.

Abstract
Catastrophic antiphospholipid syndrome, defined and documented in 1992, is a potentially fatal complication seen in patients with antiphospholipid antibody. It may arise de novo in patients not previously suspected as having an antiphospholipid syndrome, or it may complicate the course of patients currently treated for this syndrome. Precipitating or "trigger" factors have been identified in 55% of patients; the most common of these factors is infection. The precipitating factors should be avoided or energetically treated in patients with the antiphospholipid syndrome in order to prevent this "catastrophic" course. The clinical manifestations are those of multiorgan failure, and unusual vessels or organs can be involved. Treatment of the condition, with emphasis on effective anticoagulation, intravenous steroids, intravenous immunoglobulin, or plasma exchange, should be aggressive to achieve a satisfactory outcome. Regrettably, despite all available therapeutic options at this time, the mortality is still high (greater than 50%).
