What is known about the effects of vitamin D in neuropsychiatric lupus?

Abstract Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect several organs and systems. The central and/or peripheral nervous system can suffer from complications known as neuropsychiatric lupus (NPSLE). Studies have associated the manifestations of SLE or NPSLE with vitamin D deficiency. It has been shown that hypovitaminosis D can lead to cognition deficits and cerebral hypoperfusion in patients with NPSLE. In this review article, we will address the main features related to vitamin D supplementation or serum vitamin D levels with neuropsychiatric manifestations, either in patients or in animal models of NPSLE.

Cerebrovascular changes in neuro-Behcet's disease and neuropsychiatric lupus by transcranial Doppler ultrasonography and magnetic resonance imaging

ABSTRACT Introduction: Transcranial Doppler ultrasonography (TCD) is a technique that allows measurement of blood flow from the basal intracerebral vessels. It is relatively inexpensive, non-invasive, can be performed at the bedside, and allows monitoring in acute emergency settings and for prolonged periods with a high temporal resolution, making it ideal for studying the haemodynamics within the intracranial arteries in neuro-Behcet's disease (NBD) and neuro-psychiatric lupus (NPSLE). Our aim was to assess the cerebral haemodynamic patterns in patients with NBD and NPSLE using TCD, while brain lesions were examined using magnetic resonance imaging (MRI). Material and methods: Case-control prospective study of 30 neuro-Behcet's disease patients, 25 neuro-psychiatric lupus patients and 26 healthy age-matched volunteers. All patients and healthy controls were examined by TCD. Only the groups of patients underwent cranial magnetic resonance imaging (MRI). Results: Transcranial Doppler (TCD) values for middle cerebral artery (MCA), anterior cerebral artery (ACA), posterior cerebral artery (PCA), vertebral artery (VA) and basilar artery (BA) in NBD, NPSLE and control groups were measured. The results showed that there was a significant decrease in mean blood flow velocities in all the arteries examined in NBD and NPSLE patients. There was also a significant increase in the pulsatile index of PCA, VA and BA between NBD and NPSLE patients. The same results were obtained when comparing NBD versus controls. However, there was no significant difference between the NPSLE patients and the control group. The MRI lesions described were parenchymal lesions in 14 patients (46.7%), and vascular lesions in 4 patients (13.3%). Vascular lesions co-existed with parenchymal lesions (mixed lesion). Parenchymal lesions were in white matter (40%), thalamus (26.7%), brain stem (26.7%) and cerebellum (20%). While, in NPSLE, 23 patients were normal (92%) and only two patients had a vascular lesion (8%). Conclusion: There was a significant decrease in mean blood flow and a significant increase in the pulsatile index among both NBD and NPSLE patients, according to the TCD values.

Systemic lupus erythematosus combined with Aspergillus fumigatus brain abscess in 2 cases / 中华神经科杂志

Systemic lupus erythematosus (SLE) complicated with Aspergillus fumigatus brain abscess is rare and needs to be differentiated from bacterial brain abscess and neuropsychiatric lupus. This article reports 2 cases of surgically diagnosed SLE combined with Aspergillus fumigatus brain abscess. The first patient was a 34-year-old woman. Six months after the diagnosis of SLE, she developed convulsions and unconsciousness. She was diagnosed as neuropsychiatric lupus at the first hospitalization because of negative imaging. After discharge, repeated head magnetic resonance imaging revealed abscess-like signals. The second patient, a 20-year-old male, developed high fever, convulsions, and unconsciousness 3 years after the diagnosis of SLE, and head imaging showed an abscess-like signal. The etiology of the cerebrospinal fluid of the 2 patients was both negative, and the Aspergillus fumigatus brain abscess was diagnosed by pathology through abscess resection or drainage. After treatment with voriconazole, the symptoms were relieved and the lesions were subsided.

Neuropsychiatric lupus erythematosus: future directions and challenges; a systematic review and survey

This study aimed to systematically review neuropsychiatric lupus erythematosus (NPSLE) and establish a simplified diagnostic criterion for NPSLE. Publications from 1994 to 2018 in the database (Wanfang data (http://www.wanfangdata.com.cn/index.html) and China National Knowledge Internet (http://www.cnki.net)) were included. In total, 284 original case reports and 24 unpublished cases were collected, and clinical parameters were analyzed. An attempt was made to develop a set of simplified diagnostic criteria for NPSLE based on cases described in the survey and literature; moreover, and pathophysiology and management guidelines were studied. The incidence rate of NPSLE was estimated to be 12.4% of SLE patients in China. A total of 408 NPSLE patients had 652 NP events, of which 91.2% affected the central nervous system and 8.8% affected the peripheral nervous system. Five signs (manifestations, disease activity, antibodies, thrombosis, and skin lesions) showed that negative and positive predictive values were more than 70%, included in the diagnostic criteria. The specificity, accuracy, and positive predictive value (PPV) of the revised diagnostic criteria were significantly higher than those of the American College of Rheumatology (ACR) criteria (χ2=13.642, 15.591, 65.010, p<0.001). The area under the curve (AUC) for revised diagnostic criteria was 0.962 (standard error=0.015, 95% confidence intervals [CI] =0.933-0.990), while the AUC for the ACR criteria was 0.900 (standard error=0.024, 95% CI=0.853-0.946). The AUC for the revised diagnostic criteria was different from that for the ACR criteria (Z=2.19, p<0.05). Understanding the pathophysiologic mechanisms leading to NPSLE is essential for the evaluation and design of effective interventions. The set of diagnostic criteria proposed here represents a simplified, reliable, and cost-effective approach used to diagnose NPSLE. The revised diagnostic criteria may improve the accuracy rate for diagnosing NPSLE compared to the ACR criteria.

Plasmaféresis en lupus eritematoso sistémico neuropsiquiátrico

De las complicaciones sistémicas más temidas del lupus eritematoso sistémico, destaca el compromiso neuropsiquiátrico y en especial la psicosis asociada. A pesar del gran espectro de presentaciones clínicas y ambigua definición, la sospecha clínica y el registro de casos ha ido en aumento en los últimos años. Poca evidencia científica existe sobre el tratamiento de la psicosis asociada al lupus eritematoso sistémico; sin embargo, se reconoce como un fenómeno autoinmune mediado por anticuerpos, sin que exista daño estructural cerebral. Los esteroides, ciclofosfamida y rituximab forman parte de las opciones terapéuticas. Se presenta el caso de una adolescente de 13 años, con diagnóstico reciente de lupus eritematoso sistémico y en quien una de las principales manifestaciones iniciales fue afección neuropsiquiátrica, en especial psicosis refractaria. Los tratamientos con glucocorticoides y ciclofosfamida fueron inefectivos y se logró remisión exitosa únicamente con el uso de plasmaféresis terapéutica. En total, se ofrecieron 4 sesiones de plasmaféresis con albúmina humana, logrando rápida remisión de su psicosis.

One of the most feared clinical presentations of systemic lupus erythematosus is neuropsychiatric involvement, specially associated psychosis. Diagnostic definitions are not well stablished to date however clinical suspicion and case registry has been increasing over time. There is scarce evidence regarding correct therapeutic approach to psychiatric presentations of systemic lupus erythematosus, however, it is well known that it is consequence of noxious autoimmune activity of the brain without structural compromise. Corticosteroids, cyclophosphamide and rituximab are part of the pharmacologic tools available. We present a case a 13 year old adolescent with new onset systemic lupus erythematosus in whom one of the principal initial concerns was how to address intense neuropsychiatric manifestations and specially refractory psychosis. First, high doses of steroid boluses were offered with no benefit in psychiatric symptoms, then cyclophosphamide was administered, with no success. Finally, therapeutic plasma exchange was offered to the patient with rapid clinical improvement. A total of 4 sessions of plasmapheresis with human albumin were done.

Anticuerpos asociados al lupus neuropsiquiátrico: rol fisiopatológico, prevalencia y utilidad diagnóstica / Antibodies associated with neuropsychiatrie lupus: Pathophysiological role, prevalence and diagnostic usefulness

RESUMEN El lupus eritematoso sistémico (LES) es una enfermedad autoinmune multisistémica que puede comprometer cualquier órgano. El compromiso neurológico es una de las mayores causas de morbimortalidad en estos pacientes. Las manifestaciones pueden ser muy variadas y comprender compromiso tanto del sistema nervioso central como del periférico. Estas manifestaciones representan un reto para el clínico, puesto que son de difícil diagnóstico y tratamiento. Aunque existen diversas ayudas de laboratorio e imagenológicas que se han reportado como potencialmente útiles para el diagnóstico del compromiso neurológico en LES, no existe aún un estándar de oro disponible en el presente, por lo que esfuerzos para identificar biomarcadores que puedan mejorar la sensibilidad y la especificidad del diagnóstico del compromiso neurológico en LES son materia de estudio actualmente. Puesto que algunas de estas manifestaciones son mediadas o relacionadas a la presencia de anticuerpos específicos, en este artículo se revisan diferentes anticuerpos asociados al compromiso neuropsiquiátrico del LES, su posible rol fisiopatológico, su prevalencia y su asociación en esta forma de presentación clínica.

ABSTRACT Systemic lupus erythematous (SLE) is a systemic autoimmune disease with the potential to involve any organ. The neurological manifestations are one of the main causes of morbidity and mortality related to SLE, and they can be expressed in the central or peripheral nervous system. Given their complexity, their diagnosis and treatment are a challenge for clinicians. Although there are plenty of helpful laboratory tests and diagnostic imaging tools to achieve a good diagnosis, there is no gold standard available yet. Finding biomarkers with adequate sensitivity and specificity are still being studied. A review is presented in this article on the specific antibodies that have been associated with, or that may trigger, the neurological manifestations in SLE, their pathophysiological importance, prevalence, and their association with this clinical presentation of the illness.

Assessment of cognitive impairment in Systemic Lupus Erythematosus using the Mini-Mental Status Exam and the Montreal Cognitive Assessment Test-Filipino Version

Introduction@#Cognitive impairment (CI) in patients with systemic lupus erythematosus (SLE) presents with or without overt signs of central nervous involvement. The prevalence of CI is variable, ranging from 19-80%. It is often overlooked, leading to high healthcare costs and productivity loss. The usual tools for detection are expensive, time-consuming and not locally available. Detection of CI using the Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment Test (MoCA) is more clinically relevant and practical. The objectives of this study are to determine the prevalence of CI in SLE patients using MMSE/MoCA, to determine the degree of impairment in the different cognitive domains, and to characterize patients with CI in terms of disease activity, education, and employment.@*Methods@#This is a cross-sectional study of 62 SLE patients, 19 years or older, at a rheumatology clinic. Demographic and disease characteristics were collected. The validated Filipino versions of the MMSE/MoCA test were administered. Descriptive and non-parametric statistics were applied.@*Results@#Most patients are female (96.77%), below collegiate level of education (58.06%), and unemployed (70.97%). Mean disease duration is 8.92 (SD±7.03) years. Mean age at diagnosis is 28 (SD±10.30) years. Hypertension is the most common co-morbidity. Most have low lupus disease activity or are in remission (80.65%). Most are on prednisone (72.58%), with an average dose of 11.88mg/day (SD±10.66). The prevalence of CI is 38.71% (MMSE-P) and 77.42% (MoCA-P). The presence of CI is not related to educational level, employment, and disease activity.@*Conclusion@#Cognitive impairment (CI) is common in this cohort of SLE patients. Disease activity, level of education and employment do not seem to affect its occurrence. The MMSE-P and MoCA-P are rapid tools to assess the presence of CI and should be used in clinical practice to improve the quality of care for patients with lupus.

El déficit cognitivo en lupus eritematoso: a propósito de un caso / Cognitive impairment in lupus erythematosus: a case report

RESUMEN El lupus eritematoso es una enfermedad autoinmune sistémica de etiología desconocida, que afecta principalmente a mujeres entre 20 y 50 años de edad, puede manifestarse de diversas maneras clínicas. El déficit cognitivo es uno de los síndromes neuropsiquiátricos más prevalentes en dicha enfermedad, pero no se ha descrito un perfil específico del deterioro. Existen dificultades en el proceso de detección del déficit cognitivo, debido a la propia variabilidad de la clínica y a las limitaciones de los instrumentos de valoración existentes. Se recomienda el uso de pruebas de neuroimagen y la exploración neuropsicológica como formas de evaluación. La evolución y el tratamiento, tanto farmacológico como la rehabilitación cognitiva, están influidos por la etiología del deterioro. Paciente mujer de 54 años diagnosticada de lupus eritematoso, se deriva para estudio neuropsicológico por problemas de concentración y de memoria reciente, presentó alteración en pruebas de neuroimagen, pero no se presentó repercusión en la autonomía personal. Las pruebas de cribado de déficit cognitivo presentan una controvertida fiabilidad para personas con lupus eritematoso. Es necesario realizar una exploración neuropsicológica exhaustiva que incluya la valoración del rendimiento cognitivo y de la funcionalidad. Los déficits (cognitivos) son variados y el curso y el tratamiento dependerán de la etiología del déficit (primario vs. secundario).

SUMMARY Lupus erythematosus is a systemic autoimmune disease with unknown etiology that mainly affects women aged 20-50 years and it can have very different clinical manifestations. Cognitive deficit is one of the most prevalent neuropsychiatric syndromes in lupus erythematosus, but a specific profile was never described for it. There are difficulties in the assessment process due to the variability of clinical symptoms and tools limitations. Neuroi-maging and neuropsychological examination are recommended to assess cognitive impairment. The evolution and treatment (pharmacological and cognitive rehabilitation) are influenced by etiology. Case: Woman (54 years) diagnosed with lupus erythematosus who was sent to a neuropsychological study due to her concentration and short-term memory problems. She showed alteration in neuroimaging studies, but she maintains personal autonomy. Conclusion: screening tests of cognitive impairment present reliability controversial for people with lupus erythematosus. An extensive neuropsychological assessment is necessary, including cognitive performance and functionality. Cognitive Impairment are varied, and the course and treatment depend on the etiology (primary vs. secondary).

The value of microemboli detection in cerebral arteries for the diagnosis of neuropsychiatric lupus / 中华风湿病学杂志

Objective To determine the prevalence of microembolic signals (MES) by using transcranial Doppler (TCD) and to assess their association with neuropsychiatric systemic lupus erythematosus (NPSLE) and clinical presentations in patients with systemic lupus erythematosus (SLE).Methods Forty-four patients with SLE underwent TCD for 30 min were included for MES detection and their clinical information were recorded.In addition to the frequency of patients with MES,patients with MES were followed-up for sixmonth.Mann-Whitney U test and Fisher exact test were applied to investigate the clinical characteristics.Results There were 4 patients with history of NPSLE and the occurrence times were from 8 to 120 month before our study.There were 4 patients had the abnormal neuropsychiatric symptom during our study period.MES were detected in 5/44 patients (11％) with mean 17.6 per 30 min.MES were more prone to be detected in patients with higher systemic lupus erythematosus disease activity index (SLEDAI) score [16(12.5,19) vs 8(5,10),U=14.5,P=0.001],shorter course of disease [1(0.1,48.5) vs 26(13,55),U=38,P=0.028] and neuropsychiatric symptoms [3 vs 1,P=0.003].Conclusion MES may be detected in SLE patients.MES is associated with higher disease activity,shorter course of disease and NPSLE.TCD microemboli detection may be a noninvasive method to evaluate NPSLE patients.

Clinical analysis of 30 cases of nervous systemic lupus erythematosus / 中国基层医药

Objective To invetigate clinical characteristics,pathogenesis and its risk factors of neuropsychi-atric lupus erythematosus(NPLE).Methods 160 cases of SLE patients,including 30 cases of diagnosed NPLE,were analyzed retrospectively.The relationship between the appearance of NPLE and common autoantibodies,other organ involvement and SLE disease activity score(SLEDAI)were analyzed.Results Such antibody positive rates of anti nuclear antibody(ANA),anti Sm antibody,anti -RNP antibody,anti SSA antibody,anti ds -DNA antibody had no significant difference between NPLE and non NPLE,the value of χ2 was 0.947,0.013,1.194,0.023,0.745 respectively,the value of P was 0.194,0.910,0.274,0.879,0.388 respectively.Renal involvement,raynaud phenomenon,interstitial pneumonia,pulmonary thromboembolism,oral ulcer,arthritis,facial erythema,pleuritis,pericarditis,fever,pulmonary hypertension,photo -allergy and alopecia in the two groups had no difference,the value of χ2 was respectively 0.419,1.383,0.721,0.201,1.368,1.194,0.055,0.946,0.262,2.503,0.628,2.898 and 0.075,the value of P was 0.517,0.324,0.396,1.000,0.242,0.274,0.815,0.331,0.609,0.114,0.428,0.089 and 0.785 respectively.But the occurrence of hand and foot vasculitis in NPLE was significantly higher(χ2 =3.996,P =0.046).SLEDAI of NPLE was higher than non NPLE(t =8.446,P =0.000).Conclusion There was no correlation with the occurrence of NPLE and common autoantibodies,other organ involvements.Hand and foot vasculitis and higher SLEDAI(more than 15 points)were the risk factors of NPLE.Encephalopathy may be the initial manifestation to some of SLE cases. Early diagnosis and methylprednisolone pulse treatment combined with immunosuppressive therapy can effectively improve the remission of the disease,reduce mortality and improve prognosis.

Estudio multicéntrico de deterioro cognitivo en lupus eritematoso sistémico: ECLES / Multicenter study of cognitive decline in systemic lupus erythematousus: ECLES

Introducción: los pacientes lúpicos presentan un riesgo incrementado de deterioro cognitivo (DC) comparado con individuos sanos, el cual puede ser debido a múltiples causas. Objetivo: Describir la frecuencia y características del deterioro cognitivo en pacientes con lupus sin manifestaciones neuropsiquiátricas conocidas. Materiales y método: Se incluyeron pacientes de 16 a 55 años con diagnóstico de LES según criterios del Colegio Americano de Reumatología (ACR) de 1997. Se incluyeron test neuropsicológicos acordes a la propuesta del ACR y el cuestionario de Beck para evaluar depresión. Se definió DC a valores de <2 o más desvíos estándar comparada con la media de población normal en al menos un test. Se consideró focal cuando afectó una o más medidas de un dominio y multifocal en 2 o más dominios. Para comparar proporciones se utilizó prueba exacta de Fisher y para comparar variables numéricas se usó prueba de Kruskal-Wallis. Se consideró significativo un valor de p <0,05. Resultados: Se estudiaron 86 pacientes con lupus, el 90% de origen caucásico, 8% mestizos y 1% amerindio. El 82% alcanzó nivel secundario. La frecuencia de DC fue del 65% (56/86). Los dominios afectados: memoria 45%, funciones ejecutivas 30%, atención 29%, lenguaje 4,6%. Se detectó depresión en un 48% de los pacientes. Se analizaron diferentes factores de riesgo, sin hallar diferencias estadísticamente significativas a excepción de la etnia (p=0,02). Conclusión: Se halló una frecuencia elevada de deterioro cognitivo en pacientes con LES, los pacientes no caucásicos tuvieron mayor DC con diferencias significativas en comparación con los pacientes caucásicos.

Background: patients with systemic lupus erythematosus (SLE)have an increased risk of cognitive impairment (CI) compared tohealthy individuals and it may be due to multiple causes. Objective: To determine the frequency and characteristics of CI inlupus patients without known previous neuropsychiatric events. Methods: Patients aged 16 to 55 fulfilling the 1997 ACR criteria forSLE were included. The neuropsychological test battery proposedby the ACR was used to determine CI and Beck depression werealso assessed. CI was defined as values of ≤2 standard deviationscompared to the mean of the general population in at least one test. It was considered focal involvement if it affected one or more measuresof a single domain and multifocal if 2 or more domains wasaffected. To compare proportions, Fisher’s exact test was used andto compare numerical variables, Kruskal-Wallis. A value of p <0.05was considered significant. Results: 86 patients were evaluated, 90% were Caucasian, 8%mestizos and 1% Amerindian. 82% had high school. CI was foundin 65% of patients (56/86). The affected domains were: memory45%, executive functions 30%, attention 29% and language 4.6%. Depression was detected in 48% of patients. Different risk factorswere analyzed and found no statistically significant differences exceptfor ethnicity (p=0.02). Conclusion: A high frequency of CI was found in patients with SLE,non-Caucasian had higher CI with significant differences in comparisonwith Caucasian patients.

Con importante duda diagnóstica en su debut, pero la características de las lesiones (localización en corteza, ausencia en sustancia -lanca, falta de distribución arterial), serología positiva para LES y proteinuria, determino el diagnóstico de Lupus eritematoso Sistémico Neuropsiquiátrico (LENSP). El propósito de este manuscrito es informar la baja prevalencia (menor al 4%)¹ de esta manifestación y como representa un reto diagnóstico.

The case of a 42-year-old woman who presented neurologic symptoms characterized by paresthesias and right hemiparesis is presented here. Although the diagnosis was difficult at the beginning; yet, the features of the lesions (located in the cerebral cortex but not in the white matter; no arterial distribution), positive serology for SLE and proteinuria, determined the diagnosis of Neuropsychiatric systemic lupus erythematosus. The purpose of this work is to inform about the low prevalence (<4%) of the disease and how it is a diagnostic challenge.

Neuropsychiatric Lupus Presenting as a Thalamic Infarct in a Male Patient / 대한내과학회지

Systemic lupus erythematosus (SLE) is an autoimmune disease that can manifest systemically in many organs. It is most common in women of child-bearing age. Neuropsychiatric SLE is characterized by central nervous system (CNS) symptoms. CNS manifestations of SLE have been discovered in all parts of the brain, although thalamic infarcts associated with SLE are rare, especially in males. Here, we report a thalamic infarction in a 22-year-old male SLE patient.

Guillain-Barre Syndrome, Antiphospholipid Syndrome and Lupus Nephritis as Initial Manifestation of Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disease with various manifestations, while its autoantibodies and immune reactions involve multiple organs. Neuropsychiatric involvement in SLE is known to be common, however, peripheral neuropathy is relatively rare. Guillain-Barre syndrome is clinically defined as an acute demyelinating peripheral neuropathy causing weakness and numbness in the legs and arms. We describe a case of Guillain-Barre syndrome with antiphospholipid syndrome and lupus nephritis. The patient was admitted with fever and diarrhea. He developed progressive weakness of the upper and lower extremities and dysarthria with characteristic nerve conduction patterns compatible with Guillain-Barre syndrome. He also had proteinuria and gangrene of the hand and toe with antiphospholipid antibody. He received intravenous immunoglobulin and plasmapheresis for progressive neuropathy, intravenous high dose steroid to control activity of SLE, and anticoagulation for antiphospholipid syndrome. Neuropsychiatric manifestation of SLE is related to lupus activity closely, so it is important to control lupus activity.

Listeria Monocytogenes Meningitis Presenting with Bilateral Abducens Nerve Palsy in a Patient with Systemic Lupus Erythematosus / 대한류마티스학회지

Infection still remains a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). Patients with SLE are well known to have an increased risk of various opportunistic infections, which can be fatal. Central nervous system (CNS) infections such as meningitis are rare complications to SLE. On occasion, nonspecific neurologic manifestations of infectious meningitis in SLE patients can be confused with neuropsychiatric lupus. Listeria monocytogenes is a less-commonly identified organism causing meningitis in SLE patients. Here, we describe a case of Listeria monocytogenes meningitis presenting with bilateral abducens nerve (sixth cranial nerve) palsy in a patient with SLE, who was successfully treated with systemic antibiotics.
