Abstract
Neuropsychiatric systemic lupus erythematosus (NPSLE) is a potentially serious and life-threatening complication of SLE. The presentation and severity of neuropsychiatric involvement in SLE may show considerable variability. The disease can affect the neural tissue directly or may be associated with vascular involvement, mainly associated with anti-phospholipid (aPL) antibodies. A direct causal link with SLE may sometimes be challenging since there are many confounding factors and the symptoms may be non-specific. Despite its remarkable sensitivity in detecting hemorrhagic and ischemic stroke, transverse myelitis and ischemic infarction, magnetic resonance imaging (MRI) lacks the spatial resolution required to identify microvascular involvement. When standard MRI fails to detect a suspicious lesion, it is advisable to use advanced imaging modalities such as positron emission tomography (PET), single photon emission computed tomography (SPECT) or quantitative MRI, if available. Even with these advanced modalities, the specificity of neuroimaging in NPSLE remains inadequate (60-82% for MRI). Neuropsychiatric syndromes, such as cerebrovascular events, seizures and cognitive impairments appear to be associated with serum aPL antibodies. Some studies have shown that anti-ribosomal P antibodies have a low sensitivity for NPSLE and a limited contribution to the differentiation of different clinical entities. Treatment has two main goals: symptomatic relief and treatment of the disease itself. Commonly used immunosuppressants for NPSLE include cyclophosphamide (CYC), azathioprine (AZA), and mycophenolate mofetil (MMF). According to EULAR's current recommendation, strong immunosuppressants such as CYC and rituximab (RTX) should be preferred. Biologics have also been used in NPSLE. Fingolimod, eculizumab, and JAK inhibitors are potential drugs in the pipeline. Developing targeted therapies will be possible by a better understanding of the pathological mechanisms.

Abstract
PURPOSE Patients with juvenile-onset systemic lupus erythematosus (JSLE) are at a high risk of entering adulthood with disease-related morbidities like reduced bone mass and osteoporosis. This study aimed to evaluate the clinical characteristics of JSLE and to analyze the factors associated with low bone mineral density (BMD) in these patients. METHODS Children and adolescents diagnosed with JSLE at a single institution in Korea were included. Demographic, clinical, and laboratory data as well as details about the use of glucocorticoids (GCs) and disease-modifying antirheumatic drugs were collected. The lumbar spine (LS) BMD z-score was measured using dual energy x-ray absorptiometry, and lateral thoracolumbar spine radiographs were collected. RESULTS A total of 29 patients with JSLE were included in this study. Of these patients, 7 had a BMD z-score of -2.0 or lower and were designated as the low BMD group. The differences in the clinical parameters and treatment variables between the low BMD and non-low BMD groups were compared. Higher cumulative GC dose, longer GC exposure, and higher cumulative hydroxychloroquine (HCQ) dose were all associated with low BMD; among them, the main factor was the duration of GC exposure. There was no significant correlation between BMD and clinical profile, disease activity, or bone-metabolism markers. CONCLUSION The duration of GC exposure, cumulative GC dose, and cumulative HCQ dose were risk factors for low BMD in patients with JSLE, with the main factor being the duration of GC exposure. Thus, patients with JSLE should be routinely monitored for low BMD and potential fracture risks, and GC-sparing treatment regimens should be considered.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a chronic, multisystem autoimmune disorder. When SLE occurs in individuals under the age of 18, it is referred to as childhood-onset SLE (cSLE). Currently, there is a dearth of bibliometric research pertaining to cSLE. METHOD Relevant studies in the field of cSLE from 2000 to 2022 were screened from the Web of Science Core Collection (WoSCC). CiteSpace and VOSviewer software were used to visualize the annual publications, countries, institutions, authors, journals, keywords, and references, after which the authors conducted the scientific analysis. RESULTS A total of 2857 articles were included in this study, and the number of articles published in the past 20 years showed an overall upwards trend. The most prolific countries are the United States, China, and Brazil; however, the United States, Canada, and the United Kingdom are clearly superior in terms of literary influence, and there is more cooperation between them and their institutions. LUPUS (n = 389) contributed the most to the variance. Brunner, HI's contribution in the field of cSLE is outstanding. The words related to 'lupus nephritis' and 'antibodies' are important words reflected in the keyword network diagram. The keywords included 'evidence-based recommendation', 'validation', 'diagnosis' and 'adult' from 2019, and 'continuous bursts' to the present. CONCLUSION This study examined the research status of cSLE patients, discussed and analysed the research hotspots and trends in this field, and provided a reference for further research in this field to promote the development of cSLE research.

Abstract
BACKGROUND Increased malignancy frequency is well documented in adult-systemic lupus erythematosus (SLE), but with limited reports in childhood-onset SLE (cSLE) series. We explored the frequency of malignancy associated with cSLE, describing clinical and demographic characteristics, disease activity and cumulative damage, by the time of malignancy diagnosis. METHOD A retrospective case-notes review, in a nationwide cohort from 27 Pediatric Rheumatology centres, with descriptive biopsy-proven malignancy, disease activity/damage accrual, and immunosuppressive treatment were compiled in each participating centre, using a standard protocol. RESULTS Of the 1757 cSLE cases in the updated cohort, 12 (0.7%) developed malignancy with median time 10 years after cSLE diagnosis. There were 91% females, median age at cSLE diagnosis 12 years, median age at malignancy diagnosis 23 years. Of all diagnosed malignancies, 11 were single-site, and a single case with concomitant multiple sites; four had haematological (0.22%) and 8 solid malignancy (0.45%). Median (min-max) SLEDAI-2 K scores were 9 (0-38), median (min-max) SLICC/ACR-DI (SDI) score were 1 (1-5) Histopathology defined 1 Hodgkin's lymphoma, 2 non-Hodgkin's lymphoma, 1 acute lymphoblastic leukaemia; 4 gastrointestinal carcinoma, 1 squamous cell carcinoma of the tongue and 1 anal carcinoma; 1 had sigmoid adenocarcinoma and 1 stomach carcinoid; 3 had genital malignancy, being 1 vulvae, 1 cervix and 1 vulvae and cervix carcinomas; 1 had central nervous system oligodendroglioma; and 1 testicle germ cell teratoma. CONCLUSION Estimated malignancy frequency of 0.7% was reported during cSLE follow up in a multicentric series. Median disease activity and cumulative damage scores, by the time of malignancy diagnoses, were high; considering that reported in adult series.

Abstract
Objectives The aim of the study was to determine the clinical features & autoantibody profile of patients having late onset Systemic Lupus Erythematosus (SLE) and to compare with young onset SLE due to its scarce data from India. Methods All patients who fulfilled the 1997 ACR criteria for SLE were included. Late onset patients were >50 years of age and young onset were <50 years >18 years at the time of first SLE-related symptom. Clinical, laboratory, and autoantibody (ENA 25 & APLA) profiles were compared between the two groups using descriptive statistics and chi square test. Results Of the 305 patients, 69 had late onset (75.4% females). Mean age was 59.42±6.7 years (Late onset lupus) and 33.13±8.44 years (young onset lupus). The most common symptom was arthritis (60%) followed by oral ulceration (50%), fever (43%), and serositis (37.68%). Most common antibody was SSA/Ro60 (50%) and anti-SSA/Ro52 (46%). Interstitial lung disease (ILD) (14.5%), pancytopenia (13%) and diffuse alveolar haemorrhage (4.3%) were more frequent in late onset group. Statistically significant differences were found between two groups in terms of photosensitivity (p=0.009), malar rash (p=0.005), excessive hair loss (p=0.0006), Raynaud's phenomenon (p=0.001), lymphadenopathy (p=0.01), nephritis (p=0.0007), ILD (p=0.01), anti-dsDNA (p=0.005), anti-nucleosome (p=0.01), anti-Sm (p=0.007), Ribosomes P0 (p=0.0004). Conclusion This study suggests that late onset SLE has distinct clinical and serological manifestations when compared with young onset SLE patients.

Abstract
Childhood-onset systemic lupus erythematosus is a rare disease that is more prevalent in Southeast Asian children than in Western children. It is characterised by a peripubertal onset and a female predominance that rises with age. Haematological, renal, and mucocutaneous are among the frequently involved organs upon diagnosis. Some of the typical symptoms include cutaneous vasculitis, malar rash, and fever. Patients frequently had proliferative class IV lupus nephritis, which increases disease activity and kidney damage. We reported a child presented with fever associated with multiple joint pain, skin rashes over the fingers of the right hand, and generalised abdominal pain.

Abstract
We describe a rare case of pediatric systemic lupus erythematosus (pSLE) and its successful management. A nine-year-old female presented with bilateral diminution of vision, fever, and rash in the malar region, chest, abdomen, back, and arms for three months. Clinical examination and multimodal imaging revealed bilateral extensive retinal vasculitis with macular edema. Laboratory investigations revealed anemia, leucopenia, positive serum antinuclear antibody (ANA), and anti-extractable nuclear antigen (ENA) antibodies. A diagnosis of pediatric lupus retinopathy was made. Ocular and systemic manifestations responded well to intense systemic immunosuppression (pulse intravenous {IV} methylprednisolone, oral prednisolone and hydroxychloroquine {HCQ}, six cycles of IV cyclophosphamide, and oral azathioprine) along with topical steroids and laser photocoagulation, over the next 10 months. Though ocular manifestations are not a part of the diagnostic criteria for SLE, they may be markers of active systemic disease. Ophthalmologists and rheumatologists must treat this complex disease in tandem in order to provide optimum patient care.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, which may be associated with other autoimmune diseases, like autoimmune hypothyroidism. Both disorders can involve the cardiovascular system and cause pericardial effusion with cardiac tamponade. Herein, we describe a young eight-year-old female patient who initially presented with periorbital edema, cold intolerance, fatigue, and papular skin rash that was present on the face and the chest and was found to have significant pericardial effusion along with bilateral pleural effusion. Further laboratory investigation done in the hospital revealed severe hypothyroidism and positive SLE antibodies (antinuclear antibodies [ANA], antidouble strand DNA [anti-ds-DNA], and Sjögren's syndrome antibodies A and B [SS-A and SS-B]). She was administered levothyroxine and pulse methylprednisolone, which significantly improved her condition. She was discharged on maintenance therapy with regular follow-ups with a multidisciplinary team.

Abstract
Childhood-onset systemic lupus erythematosus (cSLE) is an autoimmune disease that results in significant damage and often needs more aggressive treatment. Compared to adult-onset SLE, cSLE has a stronger genetic background and more prevalent elevated type I Interferon expression. The management of cSLE is more challenging because the disease itself and treatment can affect physical, psychological and emotional growth and development. High dose oral glucocorticoid (GC) has become the rule for treating moderate to severe cSLE activity. However, GC-related side effects and potential toxicities are problems that cannot be ignored. Recent studies have suggested that GC pulse therapy can achieve disease remission rapidly and reduce GC-related side effects with a reduction in oral prednisone doses. This article reviews characteristics, including pathogenesis and manifestations of cSLE, and summarized the existing evidence on GC therapy, especially on GC pulse therapy in cSLE, followed by our proposal for GC therapy according to the clinical effects and pathogenesis.

Abstract
The pathogenesis of childhood-onset systemic lupus erythematosus (cSLE) is complex and not fully understood. It involves three key factors: genetic risk factors, epigenetic mechanisms, and environmental triggers. Genetic factors play a significant role in the development of the disease, particularly in younger individuals. While cSLE has traditionally been considered a polygenic disease, it is now recognized that in rare cases, a single gene mutation can lead to the disease. Although these cases are uncommon, they provide valuable insights into the disease mechanism, enhance our understanding of pathogenesis and immune tolerance, and facilitate the development of targeted treatment strategies. This review aims to provide a comprehensive overview of both monogenic and polygenic SLE, emphasizing the implications of specific genes in disease pathogenesis. By conducting a thorough analysis of the genetic factors involved in SLE, we can improve our understanding of the underlying mechanisms of the disease. Furthermore, this knowledge may contribute to the identification of effective biomarkers and the selection of appropriate therapies for individuals with SLE.

Abstract
Childhood-onset systemic lupus erythematosus (cSLE) impacts the daily life of children and young people. This study aimed to describe the experiences and perspectives of children and young people living with cSLE. An integrative review guided by Whittemore and Knafl was conducted. Extant empirical research published in peer-reviewed journals from 2000 to 2021 on children's self-reported experiences living with cSLE was identified from Scopus, CINAHL, Medline via PubMed, and PsycINFO via Ovid databases. Nineteen studies involving over 1400 participants were included. Four themes and fourteen sub-themes were identified: (1) challenging symptoms (disruptions to life and altered self, severity, fatigue, depression, and anxiety), (2) medicines and side effects (dreaded steroids, conflicting feelings, and medication adherence), (3) complicated life (school sports and social, giving things up, lack of understanding, and quality of life) and (4) ways of coping (family and friends, relationships with health providers, and maintaining positivity). While cSLE shares many similarities with adult-onset SLE, awareness of differences in experiences and perceptions of children and young people is crucial. The significant psychological and social impact of the disease and its treatments necessitates a comprehensive, holistic approach to managing cSLE that considers the unique needs of youth.

Lupus Sci Med 2023; 10:e000884. [PMID: 37253553 PMCID: PMC10230998 DOI: 10.1136/lupus-2022-000884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 05/13/2023] [Indexed: 06/01/2023]
Abstract
OBJECTIVE Treat-to-target (T2T) strategies are advocated to improve prognosis in childhood-onset SLE (cSLE). Proposed T2T states include SLEDAI score of <4 (SLEDAI-LD), limited corticosteroid use (low-CS), and lupus low disease activity state (LLDAS). We sought to compare T2T states for their association with cSLE prognosis under consideration of relevant disease characteristics such as pre-existing damage, race and lupus nephritis (LN). METHODS Longitudinal data from 165 patients enrolled in the Cincinnati Lupus Registry were included. LN presence was based on renal biopsy, and patients were followed up until 18 years of age. RESULTS The 165 patients (LN: 45, white: 95) entered the registry within a median of 0 (IQR: 0-1) year post diagnosis and were followed up for a median of 4 (IQR: 2-5) years during which 80%, 92% and 94% achieved LLDAS, low-CS and SLEDAI-LD. Patients with LN were significantly less likely to achieve any T2T state (all p<0.03) and required a significantly longer time to reach them (all p<0.0001). Over the study period, patients maintained low-CS, SLEDAI-LD or LLDAS for a median of 76% (IQR: 48%-100%), 86% (IQR: 55%-100%) or 39% (IQR: 13%-64%) of their follow-up. Significant predictors of failure to maintain LLDAS included LN (p≤0.0062), pre-existing damage (p≤0.0271) and non-white race (p≤0.0013). There were 22%, 20% and 13% of patients who reached SLEDAI-LD, CS-low and LLDAS and nonetheless acquired new damage. Patients with LN had a higher risk of new damage than patients without LN even if achieving low-CS (p=0.009) or LLDAS (p=0.04). CONCLUSIONS Patients with LN and pre-existing damage are at higher risk of increased future damage acquisition, even if achieving a T2T state such as LLDAS. Among proposed common T2T states, the LLDAS is the hardest to achieve and maintain. The LLDAS may be considered the preferred T2T measure as it conveys the highest protection from acquiring additional disease damage.

DNA methylation alterations in systemic lupus erythematosus: A systematic review of case-control studies. Lupus 2023; 32:363-379. [PMID: 36573333 DOI: 10.1177/09612033221148099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/28/2022]
Abstract
BACKGROUND Traditionally, the diagnosis and monitoring of disease activity in systemic lupus erythematosus (SLE) are contingent upon clinical manifestations and serological markers. However, researchers are struggling to find biomarkers with higher sensitivity and specificity. DNA methylation has been the most studied epigenetic feature in SLE. So, in this study, we performed a systematic review of studies about DNA methylation alterations in SLE patients compared to healthy controls. METHODS By searching PubMed, Scopus, and Google Scholar up to July 2022, all case-control studies in which DNA methylation of specific genes was assessed by a non-high-throughput technique and passed the quality of bias assessment were included. RESULTS In total, 44 eligible studies underwent a data extraction process. In all, 3471 SLE patients and 1028 healthy individuals were included. Among the studies that reported the patients' gender (n = 2853), 89.41% were female and 10.59% were male. Forty studies have been conducted on adult patients. The number of works on fractionated and unfractionated blood cells was almost equal. In this regard, 22 studies were conducted on whole blood or peripheral blood mononuclear cells and two studies on unfractionated white blood cells. Sorted blood cells were biological sources in 20 studies. The most investigated gene was IFI44L. Sensitivity, specificity, and diagnostic power of methylation levels were only reported for IFI44L in five studies. The most employed methylation profiling method was bisulfite sequencing polymerase chain reaction. The correlation between methylation patterns and clinical parameters was explored in 22 studies, which of them 16 publications displayed a remarkable association between DNA methylation status and clinical indices. CONCLUSIONS The methylation status of some genes especially IFI44L, FOXP3, and MX1 has been suggested as promising SLE biomarkers. However, given the conflicting findings between studies because of potential confounders such as different sample types, methylation profiling methods, and ethnicity as well as shared DNA methylation patterns of SLE and other autoimmune diseases, DNA methylation biomarkers are currently not reliable diagnostic biomarkers and do not represent surrogate markers of SLE disease activity. Future investigations on a larger scale with the discarding of limitations of previous studies would probably lead to a consensus.

Does kidney biopsy in pediatric lupus patients "complement" the management and outcomes of silent lupus nephritis? Lessons learned from a pediatric cohort. Pediatr Nephrol 2023:10.1007/s00467-022-05859-w. [PMID: 36688943 PMCID: PMC10393877 DOI: 10.1007/s00467-022-05859-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 12/10/2022] [Accepted: 12/10/2022] [Indexed: 01/24/2023]
Abstract
BACKGROUND Silent lupus nephritis (SLN) is systemic lupus erythematosus (SLE) without clinical and laboratory features of kidney involvement but with biopsy-proven nephritis. This study aims to describe and compare the baseline characteristics and outcomes of pediatric SLN with overt LN (OLN) and to identify associated risk factors and biochemical markers. METHODS In this retrospective, observational study, multivariate logistic regression and receiver operating characteristic (ROC) analyses studied age, sex, race, serum complements, anti-double-stranded-DNA antibody, anti-Smith antibody, eGFR, and proliferative nephritis. RESULTS In our cohort of 69 patients, 47 were OLN, and 22 were SLN. OLN (OR = 4.9, p = 0.03) and non-African Americans (AA) (OR = 13.0, p < 0.01) had higher odds, and increasing C3 and C4 were associated with lower odds of proliferative nephritis (OR 0.95 and 0.65 per one unit increase in C3 and C4, respectively, p < 0.01). They demonstrated a good discriminative ability to detect proliferative nephritis as assessed by the area under the ROC curve (C3 = 0.78, C4 = 0.78). C3 and C4 in proliferative SLN and OLN were comparable and significantly lower than their non-proliferative counterparts. No association was observed between age, sex, anti-double-stranded-DNA antibody, anti-Smith antibody, eGFR, and proliferative nephritis. Proliferative SLN and OLN patients received similar treatments. Adverse events were identified in the proliferative OLN only. CONCLUSIONS Lower complement levels are associated with proliferative lesions in pediatric LN-both SLN and OLN. The non-AA population had higher odds of having proliferative nephritis than the AA. Prospective, randomized, long-term follow-up of proliferative SLN patients is needed to ascertain the beneficial effect of early diagnosis and treatment.

Microstructural Changes in the Corpus Callosum in Systemic Lupus Erythematous. Cells 2023; 12:cells12030355.

Abstract
Central nervous system (CNS) involvement in childhood-onset systemic lupus erythematosus (cSLE) occurs in more than 50% of patients. Structural magnetic resonance imaging (MRI) has identified global cerebral atrophy, as well as the involvement of the corpus callosum and hippocampus, which is associated with cognitive impairment. In this cross-sectional study we included 71 cSLE (mean age 24.7 years (SD 4.6) patients and a disease duration of 11.8 years (SD 4.8) and two control groups: (1) 49 adult-onset SLE (aSLE) patients (mean age of 33.2 (SD 3.7) with a similar disease duration and (2) 58 healthy control patients (mean age of 29.9 years (DP 4.1)) of a similar age. All of the individuals were evaluated on the day of the MRI scan (Phillips 3T scanner). We reviewed medical charts to obtain the clinical and immunological features and treatment history of the SLE patients. Segmentation of the corpus callosum was performed through an automated segmentation method. Patients with cSLE had a similar mid-sagittal area of the corpus callosum in comparison to the aSLE patients. When compared to the control groups, cSLE and aSLE had a significant reduction in the mid-sagittal area in the posterior region of the corpus callosum. We observed significantly lower FA values and significantly higher MD, RD, and AD values in the total area of the corpus callosum and in the parcels B, C, D, and E in cSLE patients when compared to the aSLE patients. Low complement, the presence of anticardiolipin antibodies, and cognitive impairment were associated with microstructural changes. In conclusion, we observed greater microstructural changes in the corpus callosum in adults with cSLE when compared to those with aSLE. Longitudinal studies are necessary to follow these changes, however they may explain the worse cognitive function and disability observed in adults with cSLE when compared to aSLE.

Abstract
BACKGROUND Lupus nephritis (LN) is a frequent manifestation of childhood-onset systemic lupus erythematosus (cSLE) with a potential risk for kidney failure and poor outcomes. This study aimed to evaluate stages III, IV, and V of chronic kidney disease (CKD) and investigate risk factors for CKD in cSLE patients. METHODS We performed a nationwide observational cohort study in 27 pediatric rheumatology centers, including medical charts of 1528 cSLE patients. Data were collected at cSLE diagnosis, during follow-up, and at last visit or death, between September 2016 and May 2019. RESULTS Of 1077 patients with LN, 59 (5.4%) presented with CKD, 36/59 (61%) needed dialysis, and 7/59 (11.8%) were submitted for kidney transplantation. After Bonferroni's correction for multiple comparisons (p < 0.0013), determinants associated with CKD were higher age at last visit, urinary biomarker abnormalities, neuropsychiatric involvement, higher scores of disease activity at last visit and damage index, and more frequent use of methylprednisolone, cyclosporine, cyclophosphamide, and rituximab. In the regression model analysis, arterial hypertension (HR = 15.42, 95% CI = 6.12-38.83, p ≤ 0.001) and biopsy-proven proliferative nephritis (HR = 2.83, 95%CI = 1.70-4.72, p ≤ 0.001) increased the risk of CKD, while children using antimalarials had 71.0% lower CKD risk ((1.00-0.29) × 100%) than children not using them. The Kaplan-Meier comparison showed lower survival in cSLE patients with biopsy-proven proliferative nephritis (p = 0.02) and CKD (p ≤ 0.001). CONCLUSIONS A small number of patients manifested CKD; however, frequencies of dialysis and kidney transplantation were relevant. This study reveals that patients with cSLE with hypertension, proliferative nephritis, and absence of use of antimalarials exhibited higher hazard rates of progression to CKD. A higher resolution version of the Graphical abstract is available as Supplementary information.

Abstract
Neuropsychiatric manifestations occur frequently and are challenging to diagnose in childhood-onset systemic lupus erythematosus (SLE). Most patients with childhood-onset SLE have neuropsychiatric events in the first 2 years of disease. 30-70% of patients present with more than one neuropsychiatric event during their disease course, with an average of 2-3 events per person. These symptoms are associated with disability and mortality. Serum, cerebrospinal fluid, and neuroimaging findings have been described in childhood-onset SLE; however, only a few have been validated as biomarkers for diagnosis, monitoring response to treatment, or prognosis. The aim of this Review is to describe the genetic risk, clinical and neuroimaging characteristics, and current treatment strategies of neuropsychiatric manifestations in childhood-onset SLE.

Abstract
Background The Renal Activity Index for Lupus (RAIL) is a composite score of six urinary biomarkers (neutrophil gelatinase-associated lipocalin (NGAL), monocyte chemoattractant protein-1 (MCP-1), kidney injury molecule-1 (KIM-1), ceruloplasmin, adiponectin, and hemopexin) used to monitor lupus nephritis activity in children. We tested stability of RAIL biomarkers prior to meaningful clinical use. Methods Urine samples were tested by ELISA under shipping conditions, freeze/thaw, ambient and longer-term storage. Statistical analysis was performed via Deming Regression, Bland-Altman and Spearman Correlation Coefficient. Results Biomarker concentration were comparable to freshly collected urine following storage at -80 °C for up to 3 months, and at 4 or 25 °C up to 48 h followed by -80 °C. Neither shipping on dry or wet ice exposure nor addition of two freeze-thaw cycles led to loss of signal, with excellent Spearman Correlation coefficients under all conditions. Conclusions RAIL biomarkers are stable following short-term storage at clinically relevant conditions.

Abstract
IMPORTANCE/BACKGROUND Several diagnostic criteria have been developed to effectively diagnose systemic lupus erythematosus (SLE). Three criteria are most common, namely the American College of Rheumatology (ACR)-1997, the Systemic Lupus International Collaborating Clinics (SLICC)-2012, and the European League Against Rheumatism (EULAR/ACR)-2019. Whether they also apply to juvenile SLE is unclear. OBJECTIVE To examine the diagnostic accuracy of ACR-1997, SLICC-2012, and EULAR/ACR-2019 for juvenile SLE. DATA SOURCES A comprehensive search of PubMed, Cochrane, and Embase was conducted up to 26 March 2022. STUDY SELECTION We included all study designs in which patients had any index tests for ACR-1997, SLICC-2012, or EULAR/ACR-2019; both full-text papers and conference abstracts published in English were used. Exclusion criteria were as follows: (1) case reports; (2) adult subjects; or (3) did not report sufficient information to acquire true positive, false positive, true negative, and false negative values of diagnostic criteria. DATA EXTRACTION AND SYNTHESIS Two authors independently screened studies, extracted relevant data, and assessed the risk of bias. MAIN OUTCOMES AND MEASURES First, a meta-analysis of the diagnostic accuracy of EULAR/ACR-2019 and a hierarchical summary receiver operating characteristic (HSROC) model was performed to estimate sensitivity and specificity with 95% confidence intervals (CIs). We then carried out a network meta-analysis to compare the performances of these three diagnostic criteria. RESULTS In total, 17 relevant studies that included 2339 juvenile SLE patients were eligible to analyze pooled accuracy. In the meta-analysis, 10 studies (1613 cases) reported the diagnostic performance of EULAR/ACR-2019, showing a pooled sensitivity of 0.92 (95% CI, 0.89-0.95), pooled specificity of 0.89 (0.77-0.95), and area under HSROC of 0.96 (0.94-0.97). In the network meta-analysis, the SLICC-2012 (0.94, 0.92-0.96) had the highest sensitivity, followed by EULAR/ACR-2019 (0.93, 0.90-0.95), and ACR-1997 (0.78, 0.72-0.82); the ACR-1997 (0.96, 0.92-0.98) demonstrated the highest specificity. EULAR/ACR-2019 (0.92, 0.87-0.96) and SLICC-2012 (0.92, 0.86-0.96) had the similar specificity. CONCLUSIONS AND RELEVANCE We found that the applicability of the new EULAR/ACR-2019 criteria in juvenile SLE is not yet the best diagnostic tool. TRIAL REGISTRATION PROSPERO CRD42022321514.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder that manifests in affected individuals with a variety of clinical features and involves multiple organs. Despite recent advances over the past decades, higher morbidity and mortality have been reported by studies in patients with childhood-onset systemic lupus erythematosus (cSLE) compared to patients with adult-onset. The interplay of several factors can cause diagnostic delays resulting in worse disease activity, multiple organ damage, increased risk of hospitalization, and management with aggressive treatment. Significant factors include demographic, clinical, and socioeconomic characteristics of patients with cSLE. Moreover, despite recent advances in lupus treatment, prolonged disease duration in these young patients can result in debilitating psychosocial outcomes and can significantly impact their health-related and general quality of life (QOL). Important domains affected include patient self-esteem, education, employment, healthcare utilization, and mental health. In this review, we examined the barriers that lead to a delay in diagnosing lupus in the pediatric population and addressed cSLE morbimortality and its long-term impact on patient health-related and general QOL.

Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, known for its heterogeneous clinical presentation. Although it is rarer in children, a more severe clinical course can be seen than in adults. It is known that sleep has physiological and developmental importance in children, and there are many studies on sleep quality in adult SLE patients. The aims of this study are to evaluate the sleep habits of children and adolescents with SLE and to compare them with their healthy peers. METHODS The study included 48 children and adolescents with SLE and 64 healthy peers as a control group. The Children's Sleep Habits Questionnaire was used to evaluate the sleep characteristics of children. RESULTS The age and gender of the children were similar across groups. The bedtime resistance and night waking scores of SLE patients were significantly higher than those of the control group. Total sleep score was higher in patients with SLE than in the control group, but there was no significant difference (47.13±7.63 vs 44.61±8.17; p=0.051). Similarly, the rate of sleep disorders in the patient group (75%) was higher than that of the control group (61%), though the differences were not statistically significant (p = 0.156). There was no correlation between disease severity and sleep problems. CONCLUSION This research demonstrated that sleep disorders tend to increase in children and adolescents with SLE. Therefore, clinicians should pay attention to sleep disorders during the follow-up sessions of children and adolescents with SLE. Key Points • Sleep disorders tend to increase in children and adolescents with SLE. • Disease severity is not associated with sleep problems.

Abstract
Objective To compare the levels of Th1 (IL-12) and Th2 (IL-6 and IL10) cytokines over a two-year period among systemic lupus erythematosus patients with childhood-onset (cSLE), adult-onset (sSLE), and healthy controls, and correlate with their clinical, laboratory, and treatment manifestations. Methods The study included 63 patients with cSLE [57 (90%) women; mean age 19.7 ± 4.3 years (range = 10-29); mean disease duration 7.3 ± 4.2 years (range 2-15)], 67 patients with aSLE [65 (97%) women; mean age of 39.9 ± 11.8 years (range 21-68); disease duration 7.7 ± 3.1 years (range 4-16)], and 40 healthy controls [36 (90%) women; mean age of 29.6 ± 10 years (range 12-49)]. cSLE and aSLE patients were paired by disease duration. Clinical and laboratory manifestations, disease activity (SLEDAI), cumulative damage (SDI), and current drug exposures were evaluated. Symptoms of anxiety and depression were evaluated by the Beck inventory (BAI and BDI, respectively). Th1 (IL-12) and Th2 (IL-6 and IL-10) cytokines were measured by the ELISA test. Data were collected at four different time points (TI, TII, TIII, and TIV) and compared by non-parametric tests. Results IL-6 levels were significantly higher in aSLE patients compared to healthy controls at times I, II, and III (TI p = 0.013, TII p = 0.015, TIII p = 0.004, and TIV p = 0.634). However, no difference was observed between cSLE patients and healthy controls (TI p = 0.223, TII p = 0.613, TIII p = 0.341, and TIV p = 0.977). In addition, no difference was observed between aSLE and cSLE patients (TI p = 0.377, TII p = 0.123, TIII p = 0.105, and TIV p = 0.591). The levels of IL-12 were significantly higher in cSLE patients compared to healthy controls at all time points (TI p = 0.04, TII p < 0.001, TIII p = 0.015, and TIV p = 0.021). aSLE patients showed significantly elevated levels when compared to healthy controls at time III and IV (TI p = 0.752, TII p = 0.827, TIII p = 0.011*, and TIV p < 0.001*). cSLE patients showed significantly higher levels than aSLE patients at times I and II (TI p = 0.07*, TII p < 0.001*, TIII p = 0.998, and TIV p = 0.140). In aSLE patients, IL-6 was associated with headache (p = 0.006), arthritis (p = 0.044), and nephritis (p = 0.012); IL-10 was associated with nephritis (p = 0.043), hypocomplementemia (p = 0.001), and disease activity (p = 0.001); in these patients, IL-12 was associated with alopecia (p = 0.025) and leukopenia (p = 0.044). In cSLE patients, IL-6 was associated with arthritis (p = 0.022) and malar rash (p = 0.012). Conclusion aSLE and cSLE patients with long disease duration present similar levels of cytokines, despite differences in clinical activity patterns over time.

Abstract
BACKGROUND Disease situations are more aggressive in patients with childhood-onset systemic lupus erythematosus (cSLE) than in those with adult-onset SLE (aSLE). However, information on pregnant women with cSLE and its association with pregnancy outcomes is limited. This study aimed to compare pregnancies in patients with cSLE vs. aSLE, and further analyse the characteristics of cSLE in pregnant women and explore its association with adverse pregnancy outcomes. METHODS Altogether, data of 167 pregnancies from 150 women, including 22 pregnancies with cSLE and 145 pregnancies with aSLE, were retrospectively analysed. Characteristics and disease activity were compared between the cSLE and aSLE groups during pregnancy. Associations between cSLE and the risk of active SLE (SLEPDAI > 4), active lupus nephritis (LN), and adverse pregnancy outcomes were analysed using logistic regression. RESULTS The cSLE group had a higher incidence of active SLE (12/22 vs. 30/145, P = 0.001) and active LN (11/22 vs. 26/145, P = 0.001) than the aSLE group. In the multivariable analysis, cSLE was a risk factor for active SLE and active LN during pregnancy, with ORs of 4.742 (95%CI 1.678-13.405, P = 0.003) and 4.652 (95%CI 1.630-13.279, P = 0.004), respectively. No significant association between cSLE and the risk of composite adverse gestational outcomes was identified after sequentially adjusting pre-pregnancy characteristics and pregnancy factors (P > 0.05). CONCLUSION Disease activity of women with cSLE in pregnancy was more aggressive than that of women with aSLE, which was similar to the characteristics of non-pregnant women with SLE. cSLE might have indirect effects on the risk of adverse pregnancy outcomes through LN and active disease. Therefore, closely monitoring patients with cSLE during pregnancy is crucial.

Abstract
OBJECTIVES To describe the frequency and investigate potential associations of unemployment, need of financial assistance and health-related quality of life in adult patients with childhood-onset Systemic Lupus Erythematosus (cSLE). METHODS In this multicenter cross-sectional retrospective cohort study including cSLE adult patients, questionnaires were applied evaluating demographic characteristics, medical history, treatment, receipt of government financial assistance, work status, quality of life, economic classification, disease activity, and damage accrual. Disease activity and disease damage were measured at the study visit. RESULTS Sixty-nine cSLE patients with a median age of 21 years from two Brazilian tertiary centers were included (median disease duration 9 years). Twenty-eight (40.6%) patients were unemployed and 16 (23.2%) were receiving financial assistance or retirement pension. Work unemployment was associated with higher damage scores (OR 1.83, 95% CI 1.08 to 3.09, p = 0.024), and the need of financial assistance was associated with longer disease duration (OR 1.15, 95% CI 1.00 to 1.31, p = 0.045) and worse economic score (OR 0.87, 95% CI 0.77 to 0.99, p = 0.038). Emotional health and body image perception were the most compromised domains of quality of life but showed no association with disease parameters. Disease activity, on the other hand, was inversely associated with symptoms scores (β = -1.377, p = 0.014) and scores of adverse effects of medications (β = -1.286, p = 0.020). CONCLUSION cSLE is a disease with severe outcomes and high social burden that profoundly impacts patients. Damage accrual is a major contributor to unemployment during adulthood and its prevention must be central in the management of cSLE.

Abstract
OBJECTIVE We explored damage occurrence in patients with childhood-onset SLE (cSLE) and aimed to predict the risk of organ damage occurrence in time. METHODS The retrospective study included patients treated for cSLE at the Centre of Reference for Pediatric and Adolescent Rheumatology of the Republic Croatia over a 29-year period. RESULTS The disease development of 97 patients (77 females) with cSLE was examined. The median (Q1, Q3) follow-up time was 6.5 (2.3, 12.0) years. SDI was determined at 5 time points (6, 12, 24, 36 months, and last follow-up). Thirty-eight patients (48%) had organ damage at the last follow-up. Prepubertal group of patients showed higher SLEDAI scores at the disease onset, while post-pubertal group had significantly lower proportion of patients with relapses. We estimated the time from the first symptom to the moment of damage and our findings suggest that it is unlikely that organ damage will occur in 50% of patients in the first 6 years since the diagnosis. The number of 2019 ACR/EULAR classification criteria at the time of diagnosis associated with SDI determined after 1 year of the follow-up period. The patients who received higher doses of glucocorticoids accumulated damage faster and mycophenolate mofetil was found to be a more frequent therapy in patients with SDI ≥3. CONCLUSION Knowing that damage will most likely happen after the first 6 years after diagnosis in 50% of patients enables physicians to better predict damage occurrence. High number of 2019 ACR/EULAR criteria and treatment with glucocorticoids in childhood-onset SLE are associated with damage accrual and these findings could enable us to detect patients which should be closely monitored for higher risk of damage development.

Abstract
Aim To study the various pathological patterns of pediatric lupus nephritis (LN) by renal biopsies and to correlate the histopathological data with the clinical and biochemical outcomes. Methods This is a retrospective study in children between 1 month and 18 years of age with renal biopsy-proven lupus nephritis, conducted between January 2015 and December 2019. Various pathological and clinical parameters were compared between the groups with lupus nephritis activity and those without activity. Results Of 38 biopsy-proven lupus nephritis cases, 30 (78.9%) were in the adolescent age group, and the female gender was predominantly affected (n=30; 78.9%). Class IV proliferative lupus nephritis (n=17, 44.7%) was the most common biopsy finding, and the activity score for endocapillary hypercellularity, neutrophil infiltration, fibrinoid necrosis, hyaline deposits, and interstitial inflammation was significantly high in classes III and IV. Overall, attaining remission was less, and the risk of progression of chronic kidney disease (CKD) was higher in class IV (n=3; 7.8%). Mortality was reported in 1 out of 38 (2.6%) children. Conclusion Light microscopy and immunofluorescence studies play an important role in defining the extent of renal damage in the form of activity and chronicity indices, which are the key factors in the decision-making of lupus nephritis treatment. The prognostic relevance of the histological scoring has been evaluated, and it is evident that the activity index and chronicity index go a long way in therapeutic intervention.

Abstract
Objectives
This study aims to compare disease characteristics in patients with juvenile-onset systemic lupus erythematosus (JSLE) and adult-onset systemic lupus erythematosus (ASLE). Patients and methods
Between June 2010 and March 2020, a total of 186 patients with JSLE (23 males, 163 females; median age: 25 years; range, 20 to 30.3 years) and 236 patients with ASLE (23 males, 213 females; median age: 35 years; range, 29 to 40 years) were retrospectively analyzed. Clinical and laboratory data, treatment received, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Systemic Lupus International Collaborating Clinics (SLICC)/ACR Damage Index (SDI) scores, comorbidities and deaths were compared between the groups. Results
The JSLE patients showed statistically significant higher constitutional manifestations, cardiac manifestations, serositis, nephritis, end-stage renal disease, neurological manifestations, gastrointestinal manifestations, secondary vasculitis, Raynaud’s, livedo-reticularis, dry mouth, dry eye, ocular manifestations, avascular necrosis, hematological manifestations, and hypocomplementemia (p<0.001, p=0.016, p=0.005, p=0.001, p=0.04, p<0.001, p<0.001, p<0.001, p=0.002, p=0.043, p=0.004, p=0.03, p<0.001, p=0.01, p<0.001, and p=0.001, respectively). Median SLEDAI scores were statistically significant higher in the JSLE group, both at onset (p<0.001) and in the final follow-up visit (p<0.001). Median SLICC scores were also higher in the JSLE group (p<0.001). Mycophenolate mofetil and intravenous pulse steroids were more frequently used in the juvenile group (p<0.001 and p=0.03, respectively). Hypertension, dyslipidemia, and avascular necrosis were found to be statistically significantly higher in the JSLE group (p<0.001, p=0.006, and p=0.01, respectively). The mortality rate was statistically significantly higher in the JSLE group than the ASLE group (p<0.001). Conclusion
The JSLE patients showed more serious manifestations, higher disease activity, higher damage index, and mortality rate compared to ASLE patients. These results suggest the need of a regular follow-up and close surveillance of JSLE patients.

Abstract
Pediatric rheumatology subspecialists treat chronic autoimmune diseases with onset in childhood. Prompt diagnosis and ongoing management of these conditions are imperative to prevent damage from ongoing inflammation. Here, we aim to describe the current landscape of pediatric rheumatic disease in lower to middle-income countries (LMICs) and explore current barriers to understanding global disease burden. We then examine innovative strategies to promote a more equitable future for children and young people living with rheumatic diseases worldwide.

Abstract
Systemic lupus erythematosus (SLE) is a complex, multisystem chronic autoimmune disease. Because of its diverse phenotypes, diagnosis of SLE can be challenging, and current biomarkers are insufficient. Childhood-onset SLE (cSLE), although less prevalent, has higher morbidity and mortality, and early diagnosis is critical for improving outcomes. Many studies have focused on discovering new biomarkers to better diagnose and monitor SLE and cSLE. Herein, the authors aim to review the most investigated biomarkers in development for cSLE, focusing on those that can be measured in the blood or urine.

Abstract
In children under the age of 5 who have abnormalities in history, physical examination, and laboratory studies indicating multi-system disease, uncovering the correct diagnosis is challenging. Here, we report the course of a 4-year-old girl who presented with a change in behavior, fever, arthralgia, arthritis, and hematuria following three recent hospitalizations for pneumonia and impetigo. Serologic findings were suggestive of a rheumatologic etiology and a renal biopsy was consistent with Membranous Lupus Nephritis Class V which helped secure the diagnosis of pediatric systemic lupus erythematosus. We review the clinical features and diagnostic criteria of early-onset systemic lupus erythematosus and discuss diagnostic considerations and prognosis.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease involving multiple organs, and lupus nephritis (LN) is the most common renal complication of SLE. Belimumab is a fully humanized monoclonal antibody that can reduce the number of B cells, thereby reducing the formation of autoantibodies. Belimumab can improve SLE response index and SLE disease activity score and delay the progression of LN in both adults and children and thus plays an important role in the treatment of SLE and LN. This article reviews related research reports of belimumab used in the treatment of children and adults with SLE in China and overseas and analyzes the efficacy and safety of belimumab in pediatric patients, in order to provide a reference for the clinical application of belimumab in children with SLE.

Abstract
OBJECTIVE The aim of this study was to access the prevalence of 19 neuropsychiatric syndromes in childhood-onset systemic lupus erythematosus (cSLE), as defined by the American College of Rheumatology (ACR) in 1999, by performing a systematic review and meta-analysis of relevant publications. METHODS A literature search from April 1999 to March 2018 identified studies investigating neuropsychiatric syndromes in cSLE patients, applying 1999 ACR Case Definitions, with a sample of at least 20 patients. Case reports, small case series, reviews, articles that did not use 1999 ACR case definitions, and those with adult SLE patients were excluded. The methodological quality of the studies was determined through the Loney quality assessment. Prevalence estimates with a 95% confidence interval were combined using random-effect (DerSimonian-Laird) models. RESULTS A total of 143 articles were identified and 9 were included. In a population of 1463 cSLE patients, 351 (29.9%) presented 869 neuropsychiatric cSLE events (2.48 events/patient). The results for each syndrome were headache (52.2%), seizure disorders (48.6%), cognitive dysfunction (32.9%), mood disorder (28.3%), psychosis (22.7%), cerebrovascular disease (19.5%), acute confusional state (15.7%), movement disorder (9.4%), anxiety disorder (7.2%), aseptic meningitis (5.1%), mononeuropathy single/multiplex (4.9%), myelopathy (4.2%), demyelinating syndrome (3.2%), cranial neuropathy (2.7%), polyneuropathy (2.6%), Guillain-Barré syndrome (2.5%), autonomic disorder (1.9%), plexopathy (1.3%), and myasthenia gravis (1.3%). CONCLUSIONS Neuropsychiatric syndromes are prevalent among cSLE patients. The most prevalent were headaches, seizures, cognitive dysfunction, mood disorders, and psychosis. Determining the prevalence of each neuropsychiatric syndrome in cSLE may improve clinical awareness of these potentially fatal and disabling conditions.

Abstract
PURPOSE OF REVIEW Providing a summary of the latest research on outcome measures in juvenile idiopathic arthritis, childhood -onset systemic lupus erythematosus, and juvenile dermatomyositis. RECENT FINDINGS A rational management of patients with pediatric rheumatic diseases requires the regular assessment of the level of disease activity and damage, as well as the evaluation of therapeutic response through validated and standardized outcome measures. Ideally, such tools should be simple, feasible, and easily applicable in routine care. Recently, there has been a great deal of effort to refine existing tools and devise novel outcome measures, aiming to address the various aspects of disease impact and to improve the reliability of research studies and clinical trials. The newest outcome tools in pediatric rheumatology have markedly enlarged the spectrum of health domains assessable in a standardized way, thus increasing the reliability of evaluation of clinical response and fostering future clinical trials.

Abstract
BACKGROUND Systemic lupus erythematosus is a multi-organ inflammatory autoimmune disease; immune complexes are part of the pathogenesis, but not entirely responsible. Trisomy X is the most common female chromosomal abnormality and the role of an additional X chromosome in the development of systemic lupus erythematosus is well recognized. However, the potential complications and optimal management of childhood lupus with trisomy X remain unclear. Herein, we describe a case of childhood-onset systemic lupus erythematosus associated with severe bone complications presumably secondary to trisomy X. CASE PRESENTATION A 16-year-old Japanese girl was diagnosed with childhood-onset systemic lupus erythematosus and trisomy X. A chromosomal abnormality (47, XXX) was incidentally identified on bone marrow examination initially done to determine the cause of pancytopenia. She had a persistent headache, fever for six days, diffuse hair loss, mucosal ulcers, butterfly eruptions, and palmar erythema. Furthermore, thrombocytopenia, anemia, and erythrocyte fragmentation were detected, suggesting secondary thrombotic microangiopathy. She was initially treated with intravenous methylprednisolone pulse therapy and prescribed monthly cyclophosphamide for severe disease activity, prednisolone, mycophenolate mofetil, and hydroxychloroquine as remission maintenance drugs. She developed generalized extremity pain that had been worsening throughout the disease. Extremity magnetic resonance imaging performed 12 months after the treatment onset revealed multifocal avascular necrosis, and dual-energy X-ray absorptiometry revealed further decreased bone mineral density. High plasma levels of factor VIII were detected by additional tests for coagulation functions, and we suspected the possibility that factor VIII might cause avascular necrosis due to thrombosis. Currently, she is being treated with prednisolone and MMF for SLE. However, her extremity pain has not been managed effectively even under the administration of non-steroidal anti-inflammatory drugs and pregabalin. CONCLUSIONS An additional X chromosome has been reported to be associated with factor VIII and osteoporosis. Additionally, elevated plasma levels of FVIII is the risk factors for thrombosis, which leads to the risk of avascular necrosis. Patients with systemic lupus erythematosus complicated by trisomy X might be at a higher risk of avascular necrosis and osteoporosis that can also manifest in childhood systemic lupus erythematosus.

Abstract
Objective.Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. The American College of Rheumatology (ACR) 1997, Systemic Lupus International Collaborating Clinics (SLICC) 2012, and European League Against Rheumatism (EULAR)/ACR 2019 SLE classification criteria are formed based on data mainly from adult patients. We aimed to test the performances of the SLE classification criteria among pediatric patients with SLE.Methods.Pediatric patients with SLE (n = 262; 80.9% female) were included from 3 different centers in Turkey. As controls, 174 children (60.9% female) with other diseases who had ANA (antinuclear antibody) test results were included. The gold standard for SLE diagnosis was expert opinion.Results.The sensitivities of the ACR 1997, SLICC 2012, and EULAR/ACR 2019 criteria were 68.7%, 95.4%, and 91.6%, respectively. The specificities of the ACR 1997, SLICC 2012, and EULAR/ACR 2019 criteria were 94.8%, 89.7%, and 88.5%, respectively. Eighteen patients with SLE met the SLICC 2012 but not the EULAR/ACR 2019 criteria. Among these, hematologic involvement was prominent (n = 13; 72.2%). Eight patients with SLE fulfilled the EULAR/ACR 2019 but not the SLICC 2012 criteria. Among these, joint involvement was prominent (n = 6; 75%).Conclusion.To our knowledge, this is the largest cohort study of pediatric SLE to test the performances of all 3 classification criteria. The SLICC 2012 criteria yielded the best sensitivity, whereas the ACR 1997 criteria had the best specificity. SLICC 2012 criteria performed better than EULAR/ACR 2019 criteria. Separation of different hematological manifestations in the SLICC 2012 criteria might have contributed to the higher performance of this criteria set.

Abstract
OBJECTIVES This ongoing Phase-2, randomised, placebo-controlled, double-blind study evaluated the efficacy, safety and pharmacokinetics of intravenous belimumab in childhood-onset systemic lupus erythematosus (cSLE). METHODS Patients (5 to 17 years) were randomised to belimumab 10 mg/kg intravenous or placebo every 4 weeks, plus standard SLE therapy. Primary endpoint: SLE Responder Index (SRI4) response rate (Week 52). Key major secondary endpoints: proportion of patients achieving the Paediatric Rheumatology International Trials Organisation/American College of Rheumatology (PRINTO/ACR) response using 50 and '30 alternative' definitions (Week 52), and sustained response (Weeks 44 to 52) by SRI4 and Parent Global Assessment of well-being (Parent-global). Safety and pharmacokinetics were assessed. Study not powered for statistical testing. RESULTS Ninety-three patients were randomised (belimumab, n=53; placebo, n=40). At Week 52, there were numerically more SRI4 responders with belimumab versus placebo (52.8% vs 43.6%; OR 1.49 (95% CI 0.64 to 3.46)). PRINTO/ACR 30 alternative (52.8% vs 27.5%; OR 2.92 (95% CI 1.19 to 7.17)) and PRINTO/ACR 50 (60.4% vs 35.0%; OR 2.74 (95% CI 1.15 to 6.54)) responses were more frequent with belimumab than placebo, as were sustained responses for SRI4 (belimumab, 43.4%; placebo, 41.0%; OR 1.08 (95% CI 0.46 to 2.52)) and Parent-global (belimumab, 59.1%; placebo, 33.3%; OR 3.49 (95% CI 1.23 to 9.91)). Serious adverse events were reported in 17.0% of belimumab patients and 35.0% of placebo patients; one death occurred (placebo). Week-52, geometric mean (95% CI) belimumab trough concentration was 56.2 (45.2 to 69.8) µg/mL. CONCLUSION The belimumab intravenous pharmacokinetics and benefit-risk profile in cSLE are consistent with adult belimumab studies and the 10 mg/kg every 4 weeks dose is appropriate. TRIAL REGISTRATION NUMBER NCT01649765.

Abstract
OBJECTIVES This study on juvenile SLE patients aimed to evaluate retrospectively the impact of a tertiary center's management policy of the disease severity on its long-term progression and cumulative damage development as well as provision of quality-driven medical care (QmC). METHODS Disease activity was assessed by the Physician Global Assessment and SLEDAI-2K, flares by SELENA/SLEDAI, and damage by the pediatric SLICC/DI at diagnosis, 6 months post-diagnosis, and annually thereafter. At the same time, QmC was evaluated by relevant indices and quality of life was captured by the Greek version of the General Health Questionnaire only at the last visit. RESULTS A total of 35 patients (25/35 females) aged at diagnosis 5.5-15.16 years (median 11.83) with a median lag time to diagnosis 1.8 months had a follow-up of 5 (35/35) and 10 years (13/35), respectively. The predominant baseline manifestations were consistent with those previously reported. Out of 35 patients, 24 (68.5%) were clinically inactive at year 5, and 5/13 (38%) at year 10. All patients received immunosuppressives and 7/35 biologics in addition. At the end of their follow-up, damage was found in 9/35 patients, but none of them had a neuropsychiatric disorder. Over the study, 28/35 patients were compliant with the QmC recommendations. CONCLUSIONS An early diagnosis combined with a longitudinal quantitative assessment of the disease activity and severity contributes to the continuous evaluation of the disease state. They are the key determinants for the selection of an early, targeted, and personalized management; they restrict the cumulative damage development and contribute to an optimal outcome. Key Points • Juvenile SLE has a heavier introductory profile than in adults and an unpredictable trajectory. • The application of contemporary metric tools for assessing the disease state leads to an objective assessment and regimen selection. • An early diagnosis combined with longitudinal quantitative assessment is a key determinant for an optimal management and a minimal damage development.

[PMID: 32346765 DOI: 10.1007/s00467-020-04517-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 02/17/2020] [Accepted: 02/21/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Childhood-onset systemic lupus erythematosus (cSLE) is an autoimmune and multifactorial disease that can affect the renal system. Exposure to air pollution can trigger systemic inflammation in cSLE patients and increase risk of disease activity. We evaluated effects of individual real-time exposure to air pollutants on renal activity in cSLE patients using the Systemic Lupus Erythematosus Disease Activity Index 2000. METHODS Longitudinal panel study of 108 repetitive measures from 9 pediatric lupus patients. Over three consecutive weeks, daily individual levels of fine particulate matter (PM2.5) and nitrogen dioxide (NO2) were measured, as well as weekly clinical evaluation and laboratory tests. This was repeated every 10 weeks over a 1-year period. Specific generalized estimating equation models were used to evaluate the impact of these pollutants on risk of nephritis and anti-dsDNA > 20 UI/mL and on 24-h urine protein and serum complement (C3) levels. RESULTS An interquartile range (IQR) increase of 18.12 μg/m3 in PM2.5 daily concentration was associated with increased risk of nephritis and positive results for anti-dsDNA. Moreover, increase in 24-h urine protein and decrease in C3 serum levels also associated with exposure to pollutants. An IQR increase in PM2.57-day moving average was associated with increased risks of leukocyturia (3.4; 95% CI 2.6:4.3), positive anti-dsDNA (3.1; 95% CI 2.1:4.0), and 36.3-mg increase (95% IC 20.2:52.3) in 24-h urine protein. An IQR increase (63.1 μg/m3) in 7-day cumulative NO2 levels was associated with decreased serum C3 levels. CONCLUSIONS This prospective study suggests exposure to air pollution can trigger renal activity in cSLE patients.

Analysis of clinical and laboratory characteristics and pathology of lupus nephritis-based on 710 renal biopsies in China. Clin Rheumatol 2020; 39:3353-3363. [PMID: 32435895 DOI: 10.1007/s10067-020-05115-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 04/04/2020] [Accepted: 04/16/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVES This study aimed to analyse the clinical and laboratory characteristics of different pathologic classifications of lupus nephritis (LN) patients in terms of age at systemic lupus erythematosus (SLE) diagnosis and nephritis onset. METHOD Clinical, laboratory, and pathological data of 710 LN patients diagnosed by renal biopsy at our institution between 2000 and 2018 were retrospectively analysed. Patients were divided into the different pathological classification groups; childhood-, adult- and elderly-onset SLE groups and early- and late-onset LN groups. RESULTS Class IV occurred most frequently and had the lowest complement C3 level. There was an obvious increase in active index in class IV and class V + IV. Patients with class VI showed some clinical characteristics similar to end-stage renal disease. Patients with proliferative nephritis were younger at SLE diagnosis and had higher blood pressure, higher frequency of proteinuria and urinary erythrocyte and lower haemoglobin and complement C3. Pathologic classification between childhood-, adult- and elderly-onset SLE patients or between early- and late-onset LN patients was not significantly different. Elderly-onset SLE patients had the highest chronic index (CI), IgA, IgG and Sjögren's syndrome A antibodies and Sjögren's syndrome B antibodies rates, whereas late-onset LN patients showed significantly higher CI, haemoglobin, complement C3 and C4 but lower uric acid, IgM and IgG. CONCLUSIONS LN patients present with different clinical and laboratory characteristics according to pathological classification, age at SLE diagnosis and nephritis onset. These results might be valuable for estimating the pathology and guiding treatment and prognosis. Key Points • Patients with proliferative nephritis have more severe immune disorders, worse renal function and stronger inflammatory state. • The elderly-onset SLE patients showed a poorer condition. • The late-onset LN patients might have a more stable status.

Abstract
BACKGROUND Recently, the interleukin-17A (IL-17A) gene has emerged as a potential candidate gene for autoimmune disorders, including systemic lupus erythematosus (SLE). OBJECTIVES This study aimed to investigate whether IL-17A polymorphisms at rs2275913 G/A, rs8193036 C/T and rs3748067 C/T could be susceptibility markers for juvenile-onset SLE (JSLE) and lupus nephritis (LN) in Egyptian children and adolescents. METHODS In this multi-centre study, we genotyped 320 patients diagnosed with JSLE and 320 matched control children for three IL-17A polymorphisms at rs2275913 G/A, rs8193036 C/T and rs3748067 C/T using TaqMan probe-based real-time polymerase chain reaction. Meanwhile, IL-17A serum levels were assessed using ELISA. RESULTS The IL-17 rs2275913 A/A genotype and A allele were more represented in JSLE patients compared to the control group (21% vs. 7%, odds ratio (OR) = 3.8, 95% confidence interval (CI) 1.78-5.5, p = 0.001, pBonf = 0.003 for the A/A genotype; 37% vs. 29%, OR = 1.4, 95% CI 1.11-1.8, p = 0.003, pBonf = 0.009 for the A allele. No significant difference was found for IL-17 rs8193036 and rs3748067 single nucleotide polymorphisms (SNPs) in genotype distribution or allele frequencies (p>0.05). Patients carrying the IL-17 rs2275913 A/A genotype and A allele were more likely to develop LN (OR = 5.64, 95% CI 2.39-13.77, pBonf = 0.001 for the A/A genotype; OR = 2.73, 95% CI 1.84-4.07, pBonf = 0.02 for the A allele). CONCLUSION The IL-17 rs2275913 A allele and A/A genotype were associated with high IL-17 serum levels and may contribute to susceptibility to JSLE and the development of LN in Egyptian children and adolescents. However, no significant association was evident between the studied IL-17A SNPs and other clinical phenotypes, disease activity scores or laboratory profile of JSLE.

Higher interferon score and normal complement levels may identify a distinct clinical subset in children with systemic lupus erythematosus. Arthritis Res Ther 2020; 22:91.

Abstract
Background Systemic lupus erythematosus (SLE) is a complex multi-system disease, characterized by both autoimmune and autoinflammatory clinical and laboratory features. The role of type I interferon (IFN) in SLE has been demonstrated from the 2000s, by gene expression analyses showing significant over-expression of genes related to type I IFN signalling pathway (IFN signature). However, several studies questioned the role of measuring the intensity of IFN signature (IFN score) to chase SLE activity. We would assess if the IFN signature can help the clinical and therapeutic stratification of patients with pediatric SLE. Methods We measured the IFN score in peripheral whole blood from a series of subjects with childhood-onset SLE and correlated the results with clinical and laboratory parameters. Results Thirty-one subjects were included in the study, among which the 87% displayed a positive IFN score. The only significant relation was found for high IFN score in subjects with normocomplementemia. No correlation was observed between IFN score and SLEDAI-2K, BILAG-2004 and SLICC. Patients with high IFN score and normal complement levels also presented lower anti-dsDNA antibodies. Conclusions The integration between IFN signature analysis and complement levels may easily distinguish two groups of subjects, in which the autoimmune or autoinflammatory component of the disease seems to be prevalent.

Abstract
Previous studies have shown that high levels of air pollutants may increase activity of systemic lupus erythematosus (SLE). The aim of this study is to analyze the association between pollutants originating from the Brazilian Legal Amazon and SLE activity. This is a retrospective longitudinal cohort study with patients with SLE in the General Hospital in Cuiabá, Brazil. The association with SLE activity was measured using the SLE disease activity index (SLEDAI) and data on air quality-PM2.5 and CO, published on the websites of the State Department of Environment and the Center for Weather Forecasting and Climate Studies. To assess the effect of daily concentrations of pollutants on SLEDAI scores, the generalized estimation equation (GEE) model was used. A total of 32 female patients were assessed, in 96 doctor's appointments. The average SLEDAI score was 6 points (±5.05). GEE showed an association of disease activity with both higher rates of wildfires (p = 0.021) and average CO rate (p = 0.013), but there was no statistical association between particulate levels and SLE activity. The results suggest that variations in air pollution are associated with the activity of autoimmune rheumatic diseases.

Abstract
Childhood-onset systemic lupus erythematosus (cSLE) is a rare, chronic and systemic autoimmune disease generally with a more severe clinical phenotype than the adult-onset SLE. In both conditions, it is known that females are predominantly affected; therefore, the possible overlap of SLE and sex chromosomal abnormalities has attracted attention. Our case report describe the clinical manifestations and immunological profile of a Brazilian female with cSLE and trisomy X. The 22 year-old patient, diagnosed with cSLE at age of 11, present some features related to 47, XXX, such as difficulties at school and communication, although this was not enough to investigate for chromosome abnormalities. Cytoscan HD array screening allowed the comprehensive diagnosis for this patient. We also characterized her ancestral composition, showing that she has 6.2% higher African component than the mean from health subjects from the same geographical area. This report reinforces the role of the X chromosome dose effect for sex bias in SLE, as well as the importance of African ancestry composition in cLES. It also throws lights upon the application of high-throughput molecular analysis in a large scale cohort can be useful to detect the impact of the genomic findings for more accurate epidemiological data.

Abstract
AIMS To investigate demographic, clinical, laboratory, and immunological characteristics of patients with systemic lupus erythematosus (SLE) in southeastern areas of South Korea, and to perform survival analysis. METHODS We retrospectively evaluated 413 patients with SLE diagnosed in 3 tertiary rheumatology centers in South Korea from 1992 to 2016 by reviewing their medical charts. All patients fulfilled the 1997 revised American College of Rheumatology classification criteria for SLE. RESULTS Most patients were women (92%), and the mean (±standard deviation) age at diagnosis was 30.9 (±12.9) years. The most common clinical manifestation was leukopenia (74.3%), followed by lymphopenia (73.6%), arthritis (59.1%), malar rash (48.4%), thrombocytopenia (46.5%), oral ulcer (35.1%), and biopsy-proven lupus nephritis (31.2%). Anti-nuclear, anti-double-stranded DNA, anti-Smith, and anti-Ro antibodies were positive in 97.8%, 70.1%, 38.4%, and 63% of patients, respectively. Twenty (4.8%) patients died during a median follow-up of 83 months, and the cumulative 5-year and 10-year survival rates were 96.9% and 95.5%, respectively. The major causes of death were infection (50%) and lupus flare-up (50%). Male (hazards ratio [HR] = 7.19, P = .001), pleuritis and/or pericarditis (HR = 3.28, P = .012), childhood-onset (HR = 3.57, P = .012), and late-onset (HR = 4.65, P = .011) were independent risk factors for death. Compared with SLE cohorts in other ethnicities or countries, our patients tended to have a higher frequency of anti-Ro antibodies and hematologic disorders. CONCLUSION This study describes clinical features of SLE in South Korea and suggests a remarkable phenotypic heterogeneity of SLE.

Abstract
Objective Childhood‐onset systemic lupus erythematosus (SLE) is a severe, lifelong, multisystem autoimmune disease. Long‐term outcome data are limited. This study was undertaken to identify clinical characteristics and health‐related quality of life (HRQoL) of adults with childhood‐onset SLE. Methods Patients participated in a single study visit comprising a structured history and physical examination. Disease activity (scored using the SLE Disease Activity Index 2000 [SLEDAI‐2K]), damage (scored using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index [SDI]), and HRQoL (scored using the Short Form 36 Health Survey) were assessed. Medical records were reviewed. Results In total, 111 childhood‐onset SLE patients were included; the median disease duration was 20 years, 91% of patients were female, and 72% were white. Disease activity was low (median SLEDAI‐2K score 4), and 71% of patients received prednisone, hydroxychloroquine (HCQ), and/or other disease‐modifying antirheumatic drugs. The vast majority of new childhood‐onset SLE–related manifestations developed within 2 years of diagnosis. Damage such as myocardial infarctions began occurring after 5 years. Most patients (62%) experienced damage, predominantly in the musculoskeletal, neuropsychiatric, and renal systems. Cerebrovascular accidents, renal transplants, replacement arthroplasties, and myocardial infarctions typically occurred at a young age (median age 20 years, 24 years, 34 years, and 39 years, respectively). Multivariate logistic regression analysis showed that damage accrual was associated with disease duration (odds ratio [OR] 1.15, P < 0.001), antiphospholipid antibody positivity (OR 3.56, P = 0.026), and hypertension (OR 3.21, P = 0.043). Current HCQ monotherapy was associated with an SDI score of 0 (OR 0.16, P = 0.009). In this cohort, HRQoL was impaired compared to the overall Dutch population. The presence of damage reduced HRQoL scores in 1 domain. High disease activity (SLEDAI‐2K score ≥8) and changes in physical appearance strongly reduced HRQoL scores (in 4 of 8 domains and 7 of 8 domains, respectively). Conclusion The majority of adults with childhood‐onset SLE in this large cohort developed significant damage at a young age and had impaired HRQoL without achieving drug‐free remission, illustrating the substantial impact of childhood‐onset SLE on future life.

Abstract
Acute petrified myocardium associated with septic shock, diagnosed by autopsy has rarely been described. A 15-year-old adolescent male was diagnosed with childhood-onset systemic lupus erythematosus. One year later, he was hospitalized with fever, myalgia, headache, arthritis, vomiting, dyspnea and was diagnosed with sepsis secondary to bronchopneumonia and meningitis. Blood culture identified Neisseria meningitidis serogroup Y. Despite antibiotics and intensive therapeutic measures, he died after 29 days of hospitalization. The autopsy revealed necrotic cardiomyocytes with dystrophic calcification and interstitial fibrosis.

Elevated serum complement levels and higher gene copy number of complement C4B are associated with hypertension and effective response to statin therapy in childhood-onset systemic lupus erythematosus (SLE). Lupus Sci Med 2019; 6:e000333. [PMID: 31448126 PMCID: PMC6687033 DOI: 10.1136/lupus-2019-000333] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Revised: 06/29/2019] [Accepted: 07/01/2019] [Indexed: 12/17/2022]
Abstract
Objective Systemic lupus erythematosus (SLE) features high frequency of cardiovascular disease (CVD) and fluctuating complement levels. The clinical trial Atherosclerosis Prevention in Pediatric Lupus Erythematosus (APPLE) aimed to evaluate whether atorvastatin treatment reduced the progression of atherosclerosis in 221 patients with childhood-onset SLE (cSLE), using carotid intima media thickness (CIMT) as surrogates. We leveraged APPLE biorepository and trial data to investigate the relationship between complement and CVD in cSLE. Methods Gene copy numbers (GCNs) for total C4, C4A and C4B were measured by TaqMan-based real-time PCR and Southern blotting, and analysed with laboratory and clinical parameters through Student's t-test and χ2 analyses. Effects of total C4, C4A and C4B GCNs on the response to placebo or atorvastatin treatment and progression of CIMT were examined by regression analyses. Results At baseline, C4 protein levels strongly correlated with GCNs of total C4 (p=1.8×10-6). Each copy of C4 gene increased mean serum C4 by 3.28 mg/dL. Compared with those without hypertension (N=142), individuals with hypertension demonstrated significantly elevated serum levels for C4 and C3 at baseline and serially (C4: P=5.0×10-25; C3: P=5.84×10-20). Individuals with ≥2 C4B genes had 2.5 times the odds of having hypertension (p=0.016) and higher diastolic blood pressure (p=0.015) compared with those with C4B deficiency. At the study end, subjects with ≥2 C4B and atorvastatin treatment had significantly slower increase in CIMT compared with those treated with placebo (p=0.018). Conclusions cSLE with hypertension had elevated serum levels of C4 and C3 and higher GCN of C4B; cSLE with ≥2 C4B genes would benefit from statins therapy to prevent atherosclerosis.
