Depressive and anxiety disorders are frequently observed in patients with Systemic Lupus Erythematosus (SLE). However, the underlying mechanisms are still unknown. We conducted this survey to understand the prevalence of depression and anxiety in SLE patients without major neuropsychiatric manifestations (non-NPSLE) and to explore the relationship between emotional disorders, symptoms, autoantibodies, disease activity, and treatments in SLE. 176 SLE patients were included, and SLE disease activity index (SLEDAI), Hamilton Depression Rating Scale (HAMD), and Hamilton Anxiety Rating Scale (HAMA) were recorded to evaluate their disease activity and emotional status...

PURPOSE: Systemic lupus erythematosus (SLE) is a predominantly female autoimmune disease that can affect the central nervous system. Neuropsychiatric symptoms are found in 25-70% of SLE patients. Using diffusion tensor imaging, various studies have reported changes in white matter integrity in SLE patients with neuropsychiatric symptoms (NPSLE patients). The purpose of this study was to investigate if changes can be detected in the individual white matter tracts in SLE patients regardless if neuropsychiatric symptoms are present or not...

Neurological and psychiatric syndromes, collectively referred to as NPSLE, occur frequently in SLE. The frequency of NPSLE varies from 21 to 95%; however, only 13-38% of neuropsychiatric (NP) events could be attributable to SLE in the NPSLE SLICC inception cohort. This variability in the frequency of NPSLE is attributable to the low specificity of the ACR case definitions for SLE-attributed NP syndromes, inclusion of minor NP events in the ACR nomenclature, difficulty in ascertainment of NP events and diverse experience of rheumatologists in the clinical assessment of NP events...

Central nervous system damage, a major organ manifestation of systemic lupus erythematosus (SLE), causes significant morbidity and mortality. Designating this condition as neuropsychiatric SLE (NPSLE), the American College of Rheumatology defines it as involving the central and peripheral nervous systems and being characterized by various manifestations including stroke, seizures, and psychosis. NPSLE treatment mainly seeks to reduce damage accrual. In patients with NPSLE, the use of high-dose corticosteroids is recommended in combination with immunosuppressants, such as mycophenolate mofetil and intravenous cyclophosphamide pulse therapy...

Neuropsychiatric systemic lupus erythematosus (NPSLE) involves the central and peripheral nervous system in patients with systemic lupus erythematosus (SLE). It is essential to specify the problems faced by patients with NPSLE because it causes diverse disabilities and impairs quality of life. After performing a comprehensive evaluation, tailored management should be provided for the patient's specific problems. We report here the case of a 30-year-old female with SLE who experienced serious neuropsychiatric symptoms cerebral infarction followed by posterior reversible encephalopathy syndrome and peripheral polyneuropathy...

Systemic lupus erythematosus (SLE) is a multifactorial autoimmune disease that can affect multiple end organs. Kidney and brain are two of the organs most commonly involved in SLE. Past studies have suggested the importance of macrophages in the pathogenesis of lupus nephritis (LN). Furthermore, as the immune effectors of the brain, microglia have been implicated in pathways leading to neuropsychiatric SLE (NPSLE). We depleted macrophages and microglia using GW2580, a small colony stimulating factor-1 receptor (CSF-1R) kinase inhibitor, in MRL-lpr/lpr (MRL/lpr) mice, a classic murine lupus model that displays features of both LN and NPSLE...

This study aimed to evaluate P300 as an electrophysiological marker of cognitive function in patients with systemic lupus erythematosus (SLE) who had previous neuropsychiatric (NPSLE) involvement and were diagnosed to have cognitive impairment by standard neuropsychological tests. Event-related potentials (ERPs) were assessed by the auditory and visual oddball paradigms. Amplitude and latency of P300 at the frontal (Fz), central (Cz), and parietal (Pz) regions were determined and compared with controls. P300 detection was performed in NPSLE patients with pre-diagnosed cognitive impairment (n = 9), matched SLE patients without previous NPSLE (non-NPSLE) (n = 9), and healthy controls (n = 15)...

OBJECTIVES: Models for the attribution of neuropsychiatric manifestations to systemic lupus erythematosus (NPSLE) that incorporate timing and type of manifestation, exclusion/confounding or favouring factors have been proposed. We tested their diagnostic performance against expert physician judgment. METHODS: SLE patients with neuropsychiatric manifestations were identified through retrospective chart review. Manifestations were classified according to physician judgment as attributed to SLE, not attributed or uncertain...

Neuropsychiatric (NP) involvement in Systemic Lupus Erythematosus (SLE), can be a severe and troubling manifestation of the disease that heavily impacts patient's health, quality of life and disease outcome. It is one of the most complex expressions of SLE which can affect central, peripheral and autonomous nervous system. Complex interrelated pathogenetic mechanisms, including genetic factors, vasculopathy, vascular occlusion, neuroendocrine-immune imbalance, tissue and neuronal damage mediated by autoantibodies, inflammatory mediators, blood brain barrier dysfunction and direct neuronal cell death can be all involved...

Systemic lupus erythematosus (SLE) is a chronic inflammatory disease that involves many organs and systems. Nervous system involvement in SLE encompasses neurological and psychiatric disorders, and remains a diagnostic and therapeutic challenge. Wernicke's encephalopathy (WE) is a neurological disorder that occurs as a consequence of thiamine deficiency, and its clinical presentation resembles the neuropsychiatric events attributed to SLE (NPSLE). Differentiation between these two entities is crucial because their treatment differs greatly and can change prognosis...

The central nervous system manifestations of SLE (neuropsychiatric lupus, NPSLE) occur frequently, though are often difficult to diagnose and treat. Symptoms of NPSLE can be quite diverse, including chronic cognitive and emotional manifestations, as well as acute presentations, such as stroke and seizures. Although the pathogenesis of NPSLE has yet to be well characterized, B-cell mediated damage is believed to be an important contributor. B-cells and autoantibodies may traverse the blood brain barrier promoting an inflammatory environment consisting of glia activation, neurodegeneration, and consequent averse behavioral outcomes...

A 24-year-old female presented with catatonia and symptoms suggestive of Depressive Disorder. She also gave history of undocumented low grade irregular fever. The patient was worked up to rule out any organic cause or psychiatric illness. However, further investigations revealed immunological profile diagnostic of Systemic Lupus Erythematosus (SLE) with CNS involvement (CNS lupus). The diagnosis of SLE in this patient presenting with catatonia was of practical importance because catatonia as one of the manifestations of SLE or as a standalone presenting symptom is extremely rare...

OBJECTIVE: Anti-ribosomal-phosphoprotein antibodies (anti-Ribos.P Abs) are detected in 10-45% of NPSLE patients. Intracerebroventricular administration of anti-ribosomal-P Abs induces depression-like behaviour in mice. We aimed to discern the mechanism by which anti-Ribos.P Abs induce behavioural changes in mice. METHODS: Anti-Ribos.P Abs were exposed to human and rat neuronal cell cultures, as well as to human umbilical vein endothelial cell cultures for a control...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease involving multiple biological systems that has primary and secondary effects on the central nervous system. Neuropsychiatric manifestations of SLE (NPSLE) are common and are associated with a worse prognosis, more cumulative organ damage, and decreased quality of life. The neurocognitive disorders of NPSLE include an acute confusional state and cognitive dysfunction. The pathogenic mechanisms underlying NPSLE are likely to be multifactorial and may involve vasculopathy of predominantly small intracranial blood vessels, autoantibody production, and intrathecal production of proinflammatory cytokines...
