Objective To analyze clinical characteristics of patients with neuropsychiatric systemic lupus erythematosus (NPSLE) and to explore the risk factors affecting the occurrence of NPSLE. Methods A total of 63 NPSLE patients and 61 non-NPSLE patients were enrolled. The clinical manifestations and laboratory examination data of the two groups were collected, and the disease characteristics of NPSLE were summarized to analyze the risk factors affecting the occurrence of NPSLE by multivariate Logistic regression. Results The most common clinical manifestations of NPSLE patients were headache (39.7%), affective disorder (33.3%) and cognitive impairment (30.2%), with cranial magnetic resonance abnormalities (63.5%) and a high cerebrospinal fluid protein positive rate (52.4%). Compared with non-NPSLE patients, there were significantly increased levels of Raynaud's phenomenon, renal involvement, anti-RNP antibody, anti-ribosomal P protein, hypocomplementemia, lymphocyte-to-monocyte ratio (LMR) and neutrophil-to-lymphocyte ratio (NLR) in NPSLE patients. Multivariate Logistic regression analysis showed that renal involvement, Raynaud's phenomenon, positive anti-ribosomal P protein antibody, and elevated LMR and NLR were independent risk factors for NPSLE. Conclusion Headache is the most common symptom in patients with NPSLE, and abnormal cranial MRI and cerebrospinal fluid examination are more common. SLE patients who present with renal involvement, Raynaud's phenomenon, positive anti-ribosomal P protein antibodies, and elevated levels of LMR and NLR are more susceptible to developing NPSLE.

Systemic lupus erythematosus (SLE) associated macrophage activation syndrome (MAS) is clinically severe, with a high mortality rate and rare neuropsychiatric symptoms. In the course of diagnosis and treatment, it is necessary to actively determine whether the neuropsychiatric symptoms in patients are caused by neuropsychiatric systemic lupus erythematosus (NPSLE) or macrophage activation syndrome. This paper retrospectively analyzed the clinical data of 2 cases of SLE associated MAS with neuropsychiatric lesions, Case 1: A 30-year-old female had obvious alopecia in 2019, accompanied by emaciation, fatigue and dry mouth. In March 2021, she felt weak legs and fell down, followed by fever and chills without obvious causes. After completing relevant examinations, she was diagnosed with SLE and given symptomatic treatments such as hormones and anti-infection, but the patient still had fever. The relevant examinations showed moderate anemia, elevated ferritin, elevated triglycerides, decreased NK cell activity, and a perforin positivity rate of 4.27%, which led to the diagnosis of "pre-hemophagocytic syndrome (HPS)". In May 2021, the patient showed mental trance and babble, and was diagnosed with "SLE-associated MAS"after completing relevant examinations. After treatment with methylprednisolone, anti-infection and psychotropic drugs, the patient's temperature was normal and mental symptoms improved. Case 2: A 30-year-old female patient developed butterfly erythema on both sides of the nose on her face and several erythema on her neck in June 2019, accompanied by alopecia, oral ulcers, and fever. She was diagnosed with "SLE" after completing relevant examinations, and her condition was relieved after treatment with methylprednisolone and human immunoglobulin. In October 2019, the patient showed apathy, no lethargy, and fever again, accompanied by dizziness and vomiting. The relevant examination indicated moderate anemia, decreased NK cell activity, elevated triglycerides, and elevated ferritin. The patient was considered to be diagnosed with "SLE, NPSLE, and SLE-associated MAS". After treatment with hormones, human immunoglobulin, anti-infection, rituximab (Mabthera), the patient's condition improved and was discharged from the hospital. After discharge, the patient regularly took methylprednisolone tablets (Medrol), and her psychiatric symptoms were still intermittent. In November 2019, she developed symptoms of fever, mania, and delirium, and later turned to an apathetic state, and was given methylprednisolone intravenous drip and olanzapine tablets (Zyprexa) orally. After the mental symptoms improved, she was treated with rituximab (Mabthera). Later, due to repeated infections, she was replaced with Belizumab (Benlysta), and she was recovered from her psychiatric anomalies in March 2021. Through the analysis of clinical symptoms, imaging examination, laboratory examination, treatment course and effect, it is speculated that the neuropsychiatric symptoms of case 1 are more likely to be caused by MAS, and that of case 2 is more likely to be caused by SLE. At present, there is no direct laboratory basis for the identification of the two neuropsychiatric symptoms. The etiology of neuropsychiatric symptoms can be determined by clinical manifestations, imaging manifestations, cerebrospinal fluid detection, and the patient's response to treatment. Early diagnosis is of great significance for guiding clinical treatment, monitoring the condition and judging the prognosis. The good prognosis of the two cases in this paper is closely related to the early diagnosis, treatment and intervention of the disease.

OBJECTIVE: To investigate the clinical and immunological characteristics of systemic lupus erythematosus (SLE) with retinopathy. METHODS: Fifty SLE patients with retinopathy without hypertension and diabetes (retinopathy group) who were hospitalized in the Peking University People's Hospital from January 2009 to July 2022 were screened. Fifty SLE patients without blurred vision during the course of the SLE and without retinopathy in the fundus examinations (non-retinopathy group) matched for sex and age were selected. Their clinical manifestations, laboratory tests and lymphocyte subsets were statistically analyzed. RESULTS: The most common fundus ocular change of the SLE patients with retinopathy was cotton-wool spots (33/50, 66.0%), followed by intraretinal hemorrhage (31/50, 62.0%). Retinopathy could occur at any stage of SLE duration, with a median of 1 year (20 days to 30 years). The proportion of lupus nephritis (72.0% vs. 46.0%, P=0.008) and serositis (58.0% vs. 28.0%, P=0.002) in the retinopathy group were significantly higher than those in the non-retinopathy group. The proportion of neuropsychiatric systemic lupus erythematosus (NPSLE) in the retinopathy group was higher, but there was no significant difference between the two groups. Compared with the non-retinopathy group, the proportion of positive anti-cardiolipin antibody (30.0% vs. 12.0%, P=0.027), the SLEDAI score (median 22.0 vs. 10.5, P < 0.001), erythrocyte sedimentation rate (P < 0.001), C-reactive protein (P=0.019) and twenty-four hours urine total protein level (P=0.026) in the retinopathy group were significantly higher, and the hemoglobin level was significantly lower [(91.64±25.18) g/L vs. (113.96±18.57) g/L, P < 0.001]. The proportion of CD19⁺ B cells in peripheral blood of the patients with SLE retinopathy was significantly increased (P=0.010), the proportion of CD4⁺ T cells was significantly decreased (P=0.025) and the proportion of natural killer (NK) cells was lower (P=0.051) when compared with the non-retinopathy group. CONCLUSION Retinopathy in SLE suggests a higher activity of SLE disease with more frequent hematologic and retinal involvement. It is recommended to perform fundus examination as soon as a patient is diagnosed with SLE. SLE patients with retinopathy may have stronger abnormal proliferation of B cells, and aggressive treatment should be applied to prevent other important organs involvement.

Background: Seizures in patients with systemic lupus erythematosus (SLE) are uncommon but life-threatening; mortality rate is 25-29%. Seizure in a person with lupus may be due to lupus itself or other conditions. There are no published studies describing the causes and outcomes of seizures in Filipino patients with lupus. Objective: To describe the causes and outcomes of seizure in a cohort of patients with lupus seen at Philippine General Hospital. Methodology: We reviewed the medical records of patients with SLE) with a documented seizure and admitted between January 2016 and April 2019. History, physical examination and laboratory findings, and clinical course were obtained. Results: We included 29 patients with 31 seizure events. They were all women, mostly single, of low socio-economic status, and had poor functional capacity. Lupus was active in 77.4% (24/31), commonly with mucocutaneous or hematologic manifestations. Seizures were generalized in 87 % (27/31). Prior to seizure, one-third had headache, fever, and vomiting. There were no neurologic localizing signs. Twenty-four seizure events (77%) occurred among patients with active lupus; 16 (67%) was attributed to neuropsychiatric systemic lupus erythematosus (NPSLE) and eight (33%) to other causes: infection (tuberculous meningitis and septic encephalopathy), posterior reversible encephalopathy syndrome (PRES), uremia, arrhythmia, and eclampsia. Seven seizures in inactive lupus were not SLE-related. Mortality rate was 28%; infection was the most common cause. Seizure resolved in 97%. Mean duration of hospitalization was 26.7 days. Patients were discharged improved from 19 seizure events (18 patients); 14 had follow-up consultations, three were readmitted. There was no seizure recurrence within 30 days of discharge. There was improvement in functional capacity. Conclusion The most common cause of seizure was NPSLE, followed by infection. Despite high rates of complete seizure resolution, poor outcomes were noted in almost half of the patients. Prolonged hospitalization was common. A high rate of mortality was observed. Infection was the most common cause of mortality.

Kawasaki disease (KD) is a systemic vasculitis in infants and young children. However, its natural history has not been fully elucidated because the first case was reported in the late 1960s and patients who have recovered are just now entering middle age. Nevertheless, much evidence has raised concerns regarding the subclinical vascular changes that occur in post-KD patients. KD research has focused on coronary artery aneurysms because they are directly associated with fatality. However, aneurysms have been reported in other extracardiac muscular arteries and their fate seems to resemble that of coronary artery aneurysms. Arterial strokes in KD cases are rarely reported. Asymptomatic ischemic lesions were observed in a prospective study of brain vascular lesions in KD patients with coronary artery aneurysms. The findings of a study of single-photon emission computed tomography suggested that asymptomatic cerebral vasculitis is more common than we believed. Some authors assumed that the need to consider the possibility of brain vascular lesions in severe cases of KD regardless of presence or absence of neurological symptoms. These findings suggest that KD is related with cerebrovascular lesions in children and young adults. Considering the fatal consequences of cerebral vascular involvement in KD patients, increased attention is required. Here we review our understanding of brain vascular involvement in KD.

Primary central nervous system vasculitis (PCNSV) is rare, and the diagnosis is difficult to make because of its variable radiologic expressions. Early corticosteroid therapy often is effective. Herein we report the case of a 56-year-old man who had a well-enhanced cystic mass with severe edema in the right frontal lobe, which was initially felt to be a malignancy. Histologic examination of tissue removed at craniotomy revealed that it was a PCNSV. Despite early administration of corticosteroids, a new lesion developed within 3 days. The lesions responded to treatment with cyclophosphamide and corticosteroid.

OBJECTIVE: To investigate the clinical correlation between the manifestations of neuropsychiatric lupus (NPSLE) and brain magnetic resonance imaging (MRI). METHODS: Retrospective analysis of 65 neuropsychiatric lupus patients with brain MRI and clinical data from Peking University Third Hospital from January 2006 to October 2016, which was classified by rheumatologist, neurologists, and radiologists based on their brain MRI findings. The correlation between brain MRI findings and clinical manifestations was analyzed. RESULTS: The characteristics of the brain MRI of the 65 patients were divided into 6 categories: 16 cases (25%) with demyelination in the white matter, 15 cases (23%) with cerebrovascular disease, including 4 cases (6%) with large vascular disease and 11 cases (17%) with small vessel disease, 4 cases (6%) with inflammation, 4 cases (6%) with edema, 13 cases (20%) with multiple manifestation coexistence, and 13 cases (20%) without any abnormality. Except for 4 cases of brain MRI with edema, the clinical manifestations were only epileptic seizures, other patients had complex and diverse clinical manifestations, including epileptic seizures, lupus-like headaches, mental symptoms, blurred vision, peripheral neuropathy and disturbance of consciousness. The incidence of epileptic seizures in patients with edema of MRI is significantly higher than that of other patients, and the therapeutic response time is the shortest. CONCLUSION Multidisciplinary collaboration divides the MRI findings of neuropsychiatric lupus patients into six categories. This classification method helps clinicians to predict and intervene early possible neuropsychiatric symptoms to guide clinical treatment.

Degos disease, also referred to as malignant atrophic papulosis, was first described in 1941 by Köhlmeier and was independently described by Degos in 1942. Degos disease is characterized by diffuse, papular skin eruptions with porcelain-white centers and slightly raised erythematous telangiectatic rims associated with bowel infarction. Although the etiology of Degos disease is unknown, autoimmune diseases, coagulation disorders, and vasculitis have all been considered as underlying pathogenic mechanisms. Approximately 15% of Degos disease have a benign course limited to the skin and no history of gastrointestinal or central nervous system (CNS) involvement. A 29-year-old female with history of systemic lupus erythematosus (SLE) presented with a 2-year history of asymptomatic lesions on the dorsum of all fingers and both knees. The patient had only skin lesions and no gastrointestinal or CNS vasculitis symptoms. Her skin lesions were umbilicated, atrophic porcelain-white lesions with a rim of erythema. On the basis of clinical, histologic, and laboratory findings, a diagnosis of Degos-like lesions associated with SLE was made. The patient had been treated for SLE for 7 years. Her treatment regimen was maintained over a 2 month follow-up period, and the skin lesions improved slightly with no development of new lesions.

We report a case of primary central nervous system vasculitis (PCNSV) mimicking a cortical brain tumor. A 25-year-old woman presented with a 2-week history of headache and transient right hemiparesis. Brain magnetic resonance imaging (MRI) revealed a cortical-involving lesion on the left frontal lobe. The 6-cm sized lesion showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. The lesion had continual linear enhancement on the subcortical white matter and leptomeninges. There was no evidence of hemorrhage on susceptibility-weighted images and no diffusion restriction on diffusion-weighted images. The regional cerebral blood volume was decreased on the MR perfusion images, and spectroscopy showed increased lactate and lipid peaks. The symptoms were aggravated by fever and seizures. Biopsy was performed to rule out tumorous or inflammatory lesions. Pathologically, lymphocytes were infiltrated on the vessels, and the arachnoid membrane was thickened with inflammatory cells. The patient did not have any underlying diseases, including immune disorders. After high-dose steroid administration, her symptoms improved. Two months later, brain MRI showed a reduction in the infiltration of the T2 hyperintensity lesion with subtle subcortical enhancement. We present a case of PCNSV involving the left frontal lobe, showing vasogenic edema, mass effect, and subcortical linear contrast enhancement without hemorrhage or infarction.
