Abstract
INTRODUCTION Systemic Lupus Erythematosus (SLE) is an autoimmune disease having a variety of clinical symptoms because of multiple organs being affected at once or progressively over time. Cardiovascular system (CVS) involvement is the third most frequent cause of death in SLE, among other factors. The prognosis can be determined by looking at QT interval measurements, which have shown an elevated risk of mortality from cardiovascular causes. METHODS A case-control study was conducted on 80 patients (40 SLE patients and 40 controls) for a duration of 16 months. SLE patients and controls were identified from the general medicine and rheumatology outpatient department (OPD) based on the inclusion criteria. A thorough clinical examination was performed after obtaining a detailed clinical history. Baseline blood tests were then performed on the SLE patients and ECG was taken from both cases and controls. The serum uric acid level was measured using an automated analyzer, and the ESR was computed using Westergren's Method. The corrected QT interval (QTc) was estimated using Bazett's method. All the collected data were compared and analyzed using IBM SPSS Statistics version 23.0. RESULTS The majority of age distribution among SLE patients and controls was 21-25 years (37.5%) (Mean - 15.7 ± 14.9 years). Duration of SLE was predominantly reported between 1 and 12 months (62.5%). Very high (40%) and high (40%) lupus disease activity was recorded in the majority as per the SELENA-SLEDAI score. There was a significant difference between QTc values among SLE patients and controls (t- 8.117) (p-.0005). Upon correlating SLEDAI with the QTc, QTd, ESR, and Uric acid parameters among the SLE patients, ESR parameters were found to be moderately correlated (r-0.460) with the SLEDAI which was statistically significant (p- .003). CONCLUSION QTc interval and ESR values can be a simple and potential method for early detection of cardiac involvement in SLE patients with active disease activity. This will not only facilitate early diagnosis of disease activity, but it will also provide an affordable and accessible avenue for low and middle-income countries to decrease the SLE burden.

Abstract
Lupus remains a disease with a low prioritisation in the national agendas of many countries in Latin America, the Middle East, and Asia-Pacific, where there is a dearth of rheumatologists and limited access to new or even standard lupus treatments. There is thus an important need for education, advocacy, and outreach to prioritise lupus in these regions to ensure that patients receive the care they need. This article reviews some of the specific challenges facing the care and management of people with lupus in these regions and suggests strategies for improving patient outcomes. Specifically, we review and discuss (with a focus on the aforementioned regions) the epidemiology of lupus; economic costs, disease burden, and effects on quality of life; barriers to care related to disease assessment; barriers to effective treatment, including limitations of standard treatments, high glucocorticoid use, inadequate access to new treatments, and low adherence to medications; and strategies to improve lupus management and patient outcomes. We hope that this represents a call to action to come together and act now for the lupus community, policymakers, health authorities, and healthcare professionals to improve lupus management and patient outcomes in Latin America, the Middle East, and Asia-Pacific.

Abstract
Neuromyelitis optica spectrum disorder (NMOSD) is a rare central nervous system autoimmune disease. Aquaporin-4 antibody (AQP4-IgG) is present in over 75% of cases and criteria also exist for the diagnosis of seronegative NMOSD. AQP4-IgG NMOSD has a strong female predominance (9:1 ratio), with a median onset age of 40 years. Pregnancy in those with NMOSD is therefore an important topic. Fecundity in NMOSD is likely impaired, and for females who conceive, obstetric complications including miscarriages and pre-eclampsia are significantly higher in NMOSD compared to the general population and in related conditions such as multiple sclerosis (MS). In contrast to MS, NMOSD disease activity does not subside during pregnancy. Also, relapse risk substantially rises above pre-pregnancy rates in the early postpartum period. In view of the evolving landscape of NMOSD, we provide a contemporary update of the impacts of pregnancy in NMOSD.

Abstract
Though more common earlier in life, increasing attention is being focused on the development of cutaneous lupus erythematosus (CLE) in patients with advancing age. Studies show that CLE is more common in older populations than previously thought, and all CLE subtypes are possible in this group. Just like patients in the third or fourth decade of life, CLE may appear alongside or independent of systemic lupus erythematosus. Older populations manifesting CLE for the first time seem to have a lower risk of progression to systemic disease than younger peers, and are more commonly White. CLE must be carefully distinguished from other skin conditions that have a predilection for presentation in older populations, including rosacea, lichen planus, and other autoimmune conditions such as dermatomyositis or pemphigus/pemphigoid. It is thought that most CLE in older populations is drug-induced, with drug-induced subacute cutaneous lupus erythematosus being the most common subtype. Management of CLE in older patients focuses on eliminating unnecessary medications known to induce CLE, and otherwise treatment proceeds similarly to that in younger patients, with a few special considerations.

Abstract
Systemic lupus erythematosus (SLE) is a complex disease with an insidious clinical presentation. In up to half of the cases, SLE onset is characterized by clinical and serological manifestations that, although specific, are insufficient to fulfill the classification criteria. This condition, called incomplete SLE, could be as challenging as the definite and classifiable SLE and requires to be treated according to the severity of clinical manifestations. In addition, an early SLE diagnosis and therapeutic intervention can positively influence the disease outcome, including remission rate and damage accrual. After diagnosis, the disease course is relapsing-remitting for most patients. Time in remission and cumulative glucocorticoid exposure are the most important factors for prognosis. Therefore, timely identification of SLE clinical patterns may help tailor the therapeutic intervention to the disease course. Late-onset SLE is rare but more often associated with delayed diagnosis and a higher incidence of comorbidities, including Sjogren's syndrome. This review focuses on the SLE disease course, providing actionable strategies for early diagnosis, an overview of the possible clinical patterns of SLE, and the clinical variation associated with the different age-at-onset SLE groups.

Abstract
BACKGROUND We present clinical, biochemical, and histopathological characteristics and treatment outcomes of biopsy proven childhood lupus nephritis (LN) from a low/middle income setting treated in the current era of increased use of Mycophenolate Mofetil (MMF) and biologics. METHODS Retrospective observational study of children (1-18 years) with biopsy proven LN treated from 01.01.2010 to 31.01.2020. RESULTS 60 children met our inclusion criteria (80%, n = 48 were females). The median age at diagnosis was 11 (IQR: 9-12) years. The most common extra-renal manifestation was mucocutaneous (n = 54, 90%) and the most common kidney manifestation was edema (n = 50, 83.3%). The median 24-h urinary protein excretion was 1117.8 (IQR: 795.4-1941.7) mg/m2/day with 67% (n = 40) having nephrotic range proteinuria (>1000 mg/m2/day). 75% (n = 45) children had eGFR <90 mL/min/1.73 m2 (median eGFR = 71; IQR: 56-90 mL/min/1.73 m2). Anti-Nuclear Antibody was positive in all, both complement three and four were low in 82% (n = 49) and anti-double stranded DNA antibodies were positive in 63% (n = 38). 85% (n = 51) had proliferative LN with majority being class IV (57%, n = 34). All children received steroids for induction therapy. MMF was given as the sole induction agent in 48% (n = 29) and cyclophosphamide in 27% (n = 16). Rituximab was added in 17% (n = 10) as a rescue agent. Median follow up duration was 50 (IQR: 28-82) months. Six children (10%) died as a result of serious infections and none of them had shown complete response (CR). Out of the 52 children who had a follow up duration of at least 2 years, CR was achieved in 46 children (88%) and partial response (PR) or no response (NR) in three children (6%) each. Although children who were in CR/PR at last follow up had lower proteinuria, higher eGFR, and lower histopathology activity index at onset; low numbers in the NR group precluded us from subjecting them to any statistical correlation tests. 36% (n = 22) of children developed 36 episodes of renal flares with overall incidence of 0.14/person-year. CONCLUSION Our study on a contemporary cohort of childhood LN highlights the importance of achieving CR and its feasibility.

Abstract
Long non-coding RNA (lncRNA) TUG1 acts as a proto-oncogene, allowing the proliferation of tumor cells, and it has been related to inflammation. Therefore, we aimed in this study to investigate for the first time the role of TUG1 gene polymorphism and the TUG1 level as biomarkers in systemic lupus erythematosus (SLE) and their link to lupus nephritis 145 SLE. A total of 145 healthy controls were subjected to clinical and laboratory evaluation. The disease activity was assessed by the SLE disease activity index (SLEDAI) score. SLE patients were divided into two subgroups according to the presence of lupus nephritis. The TUG1 gene polymorphisms rs5749201 and rs886471 were determined by Sanger sequencing, and TUG1 expression was assessed by qRT-PCR. There was a significant increase in the risk of SLE AA, TA, dominant genotypes, and the A allele of rs5749201 (p < 0.001) by 4.9-, 10.1-, 6.5-, and 2.5-fold in comparison to the relative control. GG and TG, dominant genotypes and the G allele of rs886471 (p < 0.01) increased the risk by 5.09-, 11.9-, 6.5-, and 2.6-fold. AA, A allele, dominant and recessive rs5749201genotypes increased the risk of lupus nephritis by 16.6-, 7.4-, 7.1-, and 12.2-fold, respectively (p < 0.05). GG, dominant and recessive genotypes, and the G allele of rs886471 increased the risk of lupus nephritis by 17.04-, 7.8-, 9.4-, and 6.08-fold, respectively (p < 0.05). Additionally, the AG haplotype increased the risk of SLE and lupus nephritis by 2.7- and 7.8-fold, respectively. The AA rs5749201 and GG rs886471 variants are significantly associated with more severe disease (p < 0.001). TUG1 expression was significantly higher in SLE than in the control and in the lupus nephritis than in non-lupus nephritis cases (p < 0.05). Interestingly, AA rs5749201 and GG rs886471 were significantly associated with higher TUG1 levels (p < 0.001). It was also found that AA rs5749201 and high SLEDAI were predictors of lupus nephritis. Overall, our findings illustrated for the first time that TUG1 gene rs5749201 and rs886471 variants were associated with increased risk of SLE, more severe disease, and lupus nephritis, and the TUG1 level could be used as a diagnostic biomarker of SLE and lupus nephritis.

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 long-term outcome of connective tissue diseases is associated with the time from symptom onset to diagnosis. To understand gaps in care, we determine whether the length of time between symptom onset and first presentation to a rheumatologist has changed in Germany in recent decades. We analyzed data on patients diagnosed with connective tissue diseases (n = 19,662) collected from the German National Database of the Regional Cooperative Rheumatology Centers. We reviewed the onset of relevant symptoms listed at first presentations from 1993 to 2018 and performed a quantitative analysis of the intervals until first presentation to a rheumatologist. We compared time intervals and performed a linear mixed regression model with random effects to identify associated factors. Although the interval between the onset of symptoms and first presentation to a rheumatologist has diminished since 1980 for all connective tissue diseases, there has been no relevant improvement during the past 2 decades. The interval between symptoms and presentation increases with patients age for all connective tissue diseases (e.g., Systemic sclerosis; for each 10-year-increment of patients age: β 0.41, CI 0.38; 0.44). Among those diagnosed with systemic sclerosis, the mean interval was 1.5 years (95% CI 1.1; 1.8) for male patients and 2.6 years (95% CI 2.4; 2.8) for females. Patients presenting with different degrees of disease severity on their first visits and with different educational levels had similar mean intervals between symptoms and first presentation regardless of their final diagnoses. Over the past 2 decades, the time to first consultation with a rheumatologist has not continued to improve in Germany, but has stagnated at the same level. Selected patient subgroups, such as older patients with suspected connective tissue diseases and female patients with suspected systemic sclerosis, are at risk to present late and may in particular benefit from an earlier referral to a rheumatologist.

Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by a heterogeneous clinical picture that makes the diagnosis and follow-up of these patients difficult. This study aimed to identify correlations between clinical, immunological, and genetic biomarkers and clinical manifestations in SLE. A retrospective study of data from medical records and immunological and genetic studies of SLE patients in Paraguay was carried out. A descriptive analysis was performed based on the type of variable. Human leukocyte antigen (HLA) allele frequencies (DPA1, DPB1, DQA1, DQB1, and DRB1) were calculated, and univariate logistic regression analyses were performed between each of the explanatory variables and the presence or absence of each phenotype. Odds ratios, 95% confidence intervals, and p values were recorded. Associations with p<0.05 were considered statistically significant. 104 SLE patients were included: 86% were female, with a mean age of 32.80±10.36 years. An association was identified between anti-double stranded DNA (anti-dsDNA) and the presence of the renal phenotype and between anti-dsDNA and the absence of the joint and hematological phenotypes. Immunoglobulin M isotype rheumatoid factor was associated with the absence of a renal phenotype. HLA-DQB1*02:02 and HLA-DRB1*07:01 were associated with the cutaneous phenotype. An association was identified between age at disease onset over 30 years and the presence of the joint phenotype. No other associations were identified. Potential clinical, immunological, and genetic biomarkers of phenotypes have been identified in SLE Paraguayan patients.

[PMID: 37325343 PMCID: PMC10268246 DOI: 10.3389/fped.2023.1193917] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Accepted: 05/15/2023] [Indexed: 06/17/2023] Open
Abstract
Background Systemic lupus erythematosus (SLE), a multisystemic autoimmune disease, is very aggressive in pediatric-onset patients as they are prone to develop lupus nephritis (LN). Although renal C4d positivity is correlated with the activity of renal disease and SLE in adult-onset LN patients, available information for pediatric-onset patients is limited. Methods To evaluate the potential diagnostic significance of renal C4d staining in pediatric LN patients, we retrospectively detected C4d staining by immunohistochemistry on renal biopsy specimens from 58 pediatric LN patients. The clinical and laboratory data at the time of the kidney biopsy and the renal disease activity of histological injury were analyzed according to the C4d staining status. Results Glomerular C4d (G-C4d)-positive staining was detected in all 58 cases of LN. Patients with a G-C4d score of 2 displayed more severe proteinuria than those with a G-C4d score of 1 (24-h urinary protein: 3.40 ± 3.55 g vs. 1.36 ± 1.24 g, P < 0.05). Peritubular capillary C4d (PTC-C4d) positivity was found in 34 of 58 LN patients (58.62%). The PTC-C4d-positive patient groups (patients with a PTC-C4d score of 1 or 2) had higher serum creatinine and blood urea nitrogen levels as well as renal pathological activity index (AI) and SLE disease activity index (SLEDAI) scores; however, they had lower serum complement C3 and C4 levels compared to PTC-C4d-negative patients (P < 0.05). In addition, there was positive tubular basement membrane C4d (TBM-C4d) staining in 11 of 58 LN patients (18.96%), and a higher proportion of TBM-C4d-positive patients than TBM-C4d-negative patients (63.63% vs. 21.27%) had hypertension. Conclusion Our study revealed that G-C4d, PTC-C4d, and TMB-C4d were positively correlated with proteinuria, disease activity and severity, and hypertension, respectively, in pediatric LN patients. These data suggest that renal C4d is a potential biomarker for disease activity and severity in pediatric LN patients, providing insights into the development of novel identification and therapeutic approaches for pediatric-onset SLE with LN.

Comparison of clinical features, disease activity, treatment and outcomes between late-onset and early-onset patients with systemic lupus erythematosus. A sex- and year at diagnosis-matched controlled study. Adv Rheumatol 2023; 63:20. [PMID: 37127712 DOI: 10.1186/s42358-023-00297-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 03/25/2023] [Indexed: 05/03/2023] Open
Abstract
BACKGROUND Several studies have compared the clinical features and outcomes of late- and early-onset systemic lupus erythematosus (SLE) patients. However, these previous studies were uncontrolled. The current study aimed to compare late- and early-onset SLE patients while controlling for sex and year at diagnosis (± 1 year). METHODS The medical records of SLE patients in a lupus cohort from January 1994 to June 2020 were reviewed. Late-onset patients were identified as those with an age at diagnosis ≥ 50 years. The early-onset patients (age at diagnosis < 50 years) were matched by sex and year at diagnosis with the late-onset patients at a ratio of 2:1. Clinical manifestations, disease activity (mSLEDAI-2K), organ damage scores, treatment, and mortality were compared between the two groups. RESULTS The study comprised 62 and 124 late- and early-onset patients, respectively, with a mean follow-up duration of 5 years. At disease onset, when comparing the early-onset patients with the late-onset patients, the latter group had a higher prevalence rate of serositis (37.0% vs. 14.5%, p < 0.001) and hemolytic anemia (50.0% vs. 33.9%, p = 0.034) but lower prevalence rate of malar rash (14.5% vs. 37.1%, p = 0.001), arthritis (41.9% vs. 62.1%, p = 0.009), leukopenia (32.3% vs. 50.0%, p = 0.022) and lymphopenia (50.0% vs. 66.1%, p = 0.034). The groups had similar SLE disease activity (7.41 vs. 7.50), but the late-onset group had higher organ damage scores (0.37 vs. 0.02, p < 0.001). The rates of treatment with corticosteroids, antimalarial drugs, or immunosuppressive drugs were not different. At their last visit, the late-onset patients still had the same pattern of clinically significant differences except for arthritis; additionally, the late-onset group had a lower rate of nephritis (53.2% vs. 74.2%, p = 0.008). They also had a lower level of disease activity (0.41 vs. 0.57, p = 0.006) and received fewer antimalarials (67.7% vs. 85.5%, p = 0.023) and immunosuppressive drugs (61.3% vs. 78.2%, p = 0.044), but they had higher organ damage scores (1.37 vs. 0.47, p < 0.001) and higher mortality rates/100-person year (3.2 vs. 1.1, p = 0.015). After adjusting for disease duration and baseline clinical variables, the late-onset patients only had lower rate of nephritis (p = 0.002), but still received fewer immunosuppressive drugs (p = 0.005) and had a higher mortality rate (p = 0.037). CONCLUSIONS In this sex- and year at diagnosis-matched controlled study, after adjusting for disease duration and baseline clinical variables, the late-onset SLE patients had less renal involvement and received less aggressive treatment, but had a higher mortality rate than the early-onset patients.

Abstract
The preclinical phase of autoimmune disorders is characterized by an initial asymptomatic phase of varying length followed by nonspecific signs and symptoms. A variety of autoimmune and inflammatory manifestations can be present and tend to increase in the last months to years before a clinical diagnosis can be made. The phenotype of an autoimmune disease depends on the involved organs, the underlying genetic susceptibility and pathophysiological processes. There are different as well as shared genetic or environmental risk factors and pathophysiological mechanisms between separate diseases. To shed more light on this, in this narrative review we compare the preclinical disease course of four important autoimmune diseases with distinct phenotypes: rheumatoid arthritis (RA), Systemic Lupus Erythematosus (SLE), multiple sclerosis (MS) and type 1 diabetes (T1D). In general, we observed some notable similarities such as a North-South gradient of decreasing prevalence, a female preponderance (except for T1D), major genetic risk factors at the HLA level, partly overlapping cytokine profiles and lifestyle risk factors such as obesity, smoking and stress. The latter risk factors are known to produce a state of chronic systemic low grade inflammation. A central characteristic of all four diseases is an on average lengthy prodromal phase with no or minor symptoms which can last many years, suggesting a gradually evolving interaction between the genetic profile and the environment. Part of the abnormalities may be present in unaffected family members, and autoimmune diseases can also cluster in families. In conclusion, a promising strategy for prevention of autoimmune diseases might be to address adverse life style factors by public health measures at the population level.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is a relatively common rheumatic disease in children. The characteristics of blood lipid metabolism in children with LN are little reported. This study aimed to explore the relationship between blood lipid profiles and the risk of lupus nephritis (LN) in children. METHODS A total of 134 children with newly diagnosed SLE were divided into LN and non-LN groups according to pathological renal biopsy results. Clinical manifestations and blood lipid profiles were analyzed and compared between the two groups, and the relationships between blood lipid profiles and risk of LN were evaluated. RESULTS The positivity rate of an anti-dsDNA antibody and an SLE disease activity index (SLEDAI) were significantly increased, and C3 and C4 levels were significantly reduced in the LN compared with the non-LN group. The overall incidence of dyslipidemia was 79.9%, with a significantly high incidence in the LN group compared with the non-LN group. Total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and very LDLC (VLDL-C) were all higher in the LN group than those in the non-LN group. However, there was no significant difference in high-density lipoprotein cholesterol (HDL-C) between the two groups. The blood lipid levels were positively correlated with 24-hour urine protein quantification, urea, creatinine, uric acid, urinary IgG, urinary microalbumin, urinary transferrin, urinary α1 microglobulin, and urinary N-acetyl glucosidase, respectively. Receiver-operating characteristic curves showed that combined detection of TC, TG, LDL-C, and VLDL-C had higher discrimination capacity than that in individual measures. Additionally, increased TC was independently associated with the occurrence of LN. CONCLUSIONS Children with LN have significant dyslipidemia. High levels of TC, TG, LDL-C, and VLDL-C are closely related to the occurrence of pLN. Clinical attention should be paid to monitoring and managing blood lipid profiles in children with LN.

Abstract
Background With the ageing population and changes in the indications of diagnostic and protocol biopsies in systemic lupus erythematosus in recent years, an impact on the incidence and presentation of lupus nephritis (LN) is expected. The aim of this study was to analyse the epidemiological changes regarding clinical and histological presentation of LN in kidney biopsies performed from 1994 to 2019 included in the Spanish Registry of Glomerulonephritis. Methods We analysed data from 28 791 kidney biopsies from 130 Spanish hospitals comparing demographic, clinical and histological data. We divided the cohort according to the age of onset of LN into pediatric onset (<18 years), adult onset (18–50 years) and late onset (>50 years). Results The incidence of LN has decreased from 9.6% of all kidney biopsies in the period 1994–2013 to 7% in the last quarter of the observation period (2014–2019) (P < 0.001), despite an increase in the proportion of patients with LN that underwent repeat biopsies (16.6–24%; P < 0.001). The age of onset of LN has increased from 32 ± 14 to 38 ± 14 years (P < 0.001), with an increase in the proportion of late-onset LN (from 13% to 22% of incident LN; P < 0.001). There were no differences in the distribution of histological features at presentation over the study period. Patients with late-onset LN showed fewer gender differences, had lower GFR and presented with less-proliferative forms of LN compared with early-onset LN. Conclusions The frequency of biopsy-proven LN has been decreasing in recent years, despite an increasing number of repeat biopsies. Late-onset LN is increasing, presenting with worse kidney function but fewer proliferative lesions compared with younger-onset LN.

Abstract
Objective: Clinical trials are the most effective method for evaluating therapeutic strategies. The purpose of this study was to comprehensively assess the characteristics of trials on lupus nephritis (LN) and provide a reference for LN treatment and research. Methods: Registered therapeutic trials on drug interventions for LN were obtained from ClinicalTrials.gov up to December 3, 2020. The general characteristics, methodological characteristics, detailed characteristics, investigated drugs, eligibility criteria, and outcome measures of these trials were analyzed. Results: A total of 126 eligible trials were evaluated, and these trials mainly investigated the initial treatment of adult proliferative LN. Half of the trials enrolled <50 participants, and 70.7% of the trials lasted for 6-24 months. In total, 95.2% of trials adopted an interventional study design. Of intervention trials, 56.6% were in phase 2 or phase 3, 76.7% were randomized, 77.5% employed a parallel assignment, and 41.7% were masked. The eligibility criteria and outcome measures of the included trials varied and involved a variety of indicators. Chemical agents and biologics are the most widely studied immunotherapies, of which mycophenolate mofetil, tacrolimus, and rituximab are the most studied. In addition, some trials studied cell transplantation treatment. Conclusions: The majority of clinical trials for LN therapy registered on ClinicalTrials.gov investigated the initial treatment of adult proliferative LN, and most of these trials were randomized, parallel assigned, and insufficiently masked interventional trials with small scale, short duration, various eligibility criteria, and outcome measures. We hope that more large-scale, long-term multicenter, and high-quality RCT trials with standardized inclusion criteria/exclusion criteria and treatment effect evaluation systems will be conducted and that more energy and funding will be put into exploring biological products and stem cell therapies. In addition, trials for membranous LN, childhood-onset LN, and maintenance phase LN are needed to establish optimal treatment strategies.

Abstract
OBJECTIVES This retrospective study aimed to analyze the clinical and laboratory features, disease activity, and outcomes of juvenile systemic lupus erythematosus (jSLE) patients from southern China. METHODS A total of 173 jSLE patients who attended Rheumatology and Immunology Department of Meizhou People's Hospital between January 2010 and December 2019 are included for analysis. RESULTS The mean age of disease onset was 13.65 ± 2.80 (range, 5-17). The median age at diagnosis was 13.98 ± 2.88 (range, 5-17) years. The female to male ratio was 6.5:1. Renal involvement was the most prevalent clinical feature, occurred in 71.7% of the patients. A total of 27 (15.6%) patients underwent renal biopsy, and the most common type of renal pathology was class IV (44.4%). Our study demonstrated differences in antibody clusters for which the positivity rates of anti-dsDNA antibodies and anti-Sm antibodies were higher than the other jSLE cohorts reported in China and worldwide. Cyclophosphamide combined with corticosteroids was the main treatment medication. The mean SLE Disease Activity Index (SLEDAI) score at diagnosis was 14.3 ± 7.6 (range, 3-38). Five patients died during the initial diagnosis and treatment. Infection was the major cause of death. CONCLUSION The jSLE patients in this cohort had a higher prevalence of renal involvement, anti-dsDNA antibodies, and anti-Sm antibodies. Multicenter studies are needed to clarify the different clinical features of jSLE in southern China. KEY POINTS • A single-center study of juvenile systemic lupus erythematosus in clinical and laboratory features. • The jSLE patients had a higher prevalence of renal involvement and antibody disorder.

Abstract
Background Systemic lupus erythematosus (SLE) is a systemic autoimmune inflammatory disorder associated with premature atherosclerosis and increased cardiovascular risk. Systemic inflammation is an emerging risk factor for coronary microvascular dysfunction (CMD). We aimed to test whether CMD, defined as abnormal myocardial flow reserve (MFR) by positron emission tomography‐computed tomography, would be independently associated with SLE after adjusting for nonobstructive atherosclerotic burden and common cardiovascular risk factors. Methods and Results Consecutive patients with SLE who underwent symptom‐prompted stress cardiac positron emission tomography‐computed tomography were included (n=42). Obstructive coronary artery disease and systolic dysfunction were excluded. MFR was quantified by positron emission tomography‐computed tomography, and CMD was defined as MFR <2. We frequency matched patients who did not have SLE and had symptom‐prompted positron emission tomography studies on age, sex, and key cardiovascular risk factors (n=69). The attenuation correction computed tomography scans were reviewed for qualitative assessment of coronary artery calcium. Patients with SLE had a more severe reduction in global MFR compared with controls and a higher prevalence of CMD, despite a similar degree of nonobstructive atherosclerotic burden (1.91±0.5 versus 2.4±0.7, respectively, P<0.0001; CMD, 57.1% versus 33.3%, respectively, P=0.017). Conclusions We demonstrated that patients with SLE with cardiac symptoms without obstructive coronary artery disease have a high prevalence of coronary vasomotor abnormalities. In comparison with symptomatic matched controls, patients with SLE have a more severe reduction in MFR that is not accounted for by common cardiovascular factors or atherosclerotic burden.

Abstract
BACKGROUND Age at disease onset may modulate systemic lupus erythematosus (SLE), but its relation to cutaneous/extracutaneous manifestation remains understudied. OBJECTIVE To compare the cutaneous, systemic features, laboratory characteristics, and disease severity between late- and adult-onset SLE patients. METHODS Analyses of the cutaneous, systemic involvement, laboratory investigations, SLE disease activity index 2000 (SLEDAI-2K), and disease damage were performed to compare between groups. RESULTS Of 1006 SLE patients, 740 and 226 had adult- (15-50 years) and late-onset (>50 years), respectively. Among 782 with cutaneous lupus erythematosus (CLE), acute CLE (ACLE) and chronic CLE (CCLE) were more common in the adult- and late-onset SLE, respectively (p = 0.001). Multivariable logistic regression analysis demonstrated that male patients and skin signs, including papulosquamous subacute CLE, discoid lupus erythematosus, and lupus profundus, were associated with late-onset SLE (all p < 0.05). Late-onset SLE had lower lupus-associated autoantibodies, and systemic involvement (all p < 0.05). ACLE, CCLE, mucosal lupus, alopecia, and non-specific lupus were related to higher disease activity in adult-onset SLE (all p < 0.001). There was no difference in the damage index between the two groups. CONCLUSIONS Late-onset SLE had a distinct disease expression with male predominance, milder disease activity, and lower systemic involvement. Cutaneous manifestations may hold prognostic values for SLE.

Abstract
Systemic lupus erythematosus is a rare lifelong multi-systemic autoimmune condition. Juvenile-onset SLE (JSLE) is recognized to have a more active disease course when compared with adult-onset disease and patients have a worse long-term survival. Kidney involvement occurs in over 50% of children and treatment decisions are guided by the histological classification. Several international groups have produced treatment protocols that rely on an intense period of immunosuppression to halt the acute kidney inflammatory process, followed by maintenance therapy with close observation for disease improvement and prompt evaluation of disease flares. A reduced glomerular filtration rate at presentation is predictive of later stage chronic kidney disease (CKD) in multivariate analysis. Kidney remission remains suboptimal with only 40-60% of patients achieving complete remission. Kidney flares are seen in over a third of patients. The rate of CKD 5 is reported to be up to 15% and the presence of lupus nephritis (LN) has an established link with an associated increase in mortality. In established kidney failure, transplantation seems to be the optimal kidney replacement modality for this group of patients, ideally after a period of disease quiescence. Modified outcome measures in clinical trials have demonstrated that biologic agents can be effective in this disease. Current biologic agents under investigation include obinutuzimab, belimumab, atacicept, anifrolumab, tocilizumab, eculizumab, dapirolizumab, and abatacept. Future research should focus on discovering early disease biomarkers, including surrogates for later cardiovascular disease, and evaluating biological agents as adjuncts to improve the rates of complete remission and subsequently influence the kidney outcome. The aim of this review article is to summarize the current kidney outcomes for this disease with a view to identifying key areas that may help to reduce the risk of long-term CKD.

Abstract
INTRODUCTION The aim of this study was to investigate the characteristics and outcome of systemic lupus erythematosus (SLE) among elderly-onset patients. METHODS This study included 575 SLE patients managed at Cairo, Alexandria, and Helwan universities from August 2014 to 2018: of whom 49 (8.5%), 420 (73%), and 106 (18.4%) were elderly- (> 50 years), adult- (17-50 years), and juvenile- (≤ 16 years) onset patients, respectively. Cumulative characteristics were recorded. Disease activity at the last visit was investigated through the Systemic Lupus Erythematosus Disease Activity Index-2K (SLEDAI-2K), whereby lupus low disease activity (LLDA) was defined as a SLEDAI-2K score ≤ 4. The disease outcome was assessed through investigating disease damage (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)) and the prevalence of mortality. Quantitative and categorical data were compared using Kruskal-Wallis and Mann-Whitney tests, and chi-square (χ2) test, respectively. RESULTS Late-onset SLE (LSLE) patients demonstrated the lowest prevalence of constitutional and mucocutaneous manifestations (p < 0.001), serositis (p = 0.006), nephritis (p < 0.001), neuropsychiatric involvement (p < 0.001), and hypocomplementinemia (p < 0.001), but showed the highest prevalence of comorbidities and multimorbidity (comorbidities ≥ 2) (p < 0.001), and positive anti-ds DNA antibodies (p < 0.001). Elderly-onset patients demonstrated the lowest SLEDAI-2K and SDI scores, achieved LLDA the most (p < 0.001), and developed any damage (SDI ≥ 1) the least (p < 0.001). The prevalence of mortality was comparable across the three age groups (p = 0.6). CONCLUSIONS Late-onset SLE patients (8.5%) showed the lowest prevalence of major organ involvement and the highest prevalence of comorbidities, and demonstrated more favorable disease activity and damage indices.Key Points• The disease characteristics and outcome among LSLE patients are characterized by being controversial, with studies from the Middle East being limited. Our cohort constituted of 8.5% elderly-onset SLE patients-who were characterized by the lowest prevalence of major organ involvement and the lowest activity and damage indices-making the disease pattern more favorable in this age group, despite being characterized by the highest prevalence of comorbidities.

Abstract
Objective Systemic lupus erythematosus (SLE) rarely has a late onset. Late-onset SLE (LSLE) has a milder course and less organ involvement. The purpose of the present study was to compare the clinical and laboratory (lab) findings of SLE regarding age at onset. Materials and Methods Seventy-two patients with SLE were included in the study. The age at onset was considered adult-onset SLE (ASLE) if it was <50 years and LSLE if it was ≥50 years. Lab parameters and clinical findings were compared accordingly. Results Overall, 41 (56.9%) patients had ASLE, and 31 (43.05%) patients had LSLE based on the age at onset. The ratio of female-to-male patients was higher in ASLE, and no significant difference was found with regard to gender distribution (12.6:1 and 5.2:1 for ASLE and LSLE, respectively; p=0.239). While malar rash and fever were more common in ASLE, no difference was found regarding the other clinical findings. Only IgG anti-cardiolipin was more common in LSE between the lab parameters. Conclusion Although it is known that LSLE has a milder course and less organ involvement, there are differences in clinical and lab findings and organ involvement in various studies. The results of our study showed no significant difference in organ involvement between ASLE and LSLE.

Abstract
Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that may affect any organ of the body. Lupus nephritis (LN) is a frequent and serious complication of SLE. We report a case of an 80-year-old woman who was initially diagnosed with late-onset SLE and eventually developed LN in the setting of normal complements, double-stranded DNA, C-reactive protein, erythrocyte sedimentation rate, and urine sediment. She developed abnormal renal function (creatinine of 1.7 mg/dl) and mild proteinuria (1-2+) without hematuria. Renal biopsy showed class IV lupus glomerulonephritis, active and chronic. The patient was started on mycophenolate mofetil which led to improvement of proteinuria and stabilization of creatinine. The suspicion for LN in a patient with late-onset SLE should remain high when there is development of suspicious renal or urinary abnormalities even if laboratory values do not suggest high disease activity and urinary sediment is normal. To our knowledge, this is one of the oldest patients with biopsy-proven LN and late-onset SLE.

Abstract
A 70-year-old Japanese woman presented to our hospital with gait disturbance and cognitive dysfunction. Since she had arthritis, lymphopenia, hypocomplementemia, and anti-nuclear and anti-double-stranded DNA antibodies, she was diagnosed with systemic lupus erythematosus (SLE). T2-weighted magnetic resonance imaging revealed bilateral hyperintensities in the putamen. Based on her cognitive impairment, muscle rigidity, and high levels of interleukin-6 in the cerebrospinal fluid, we believed she had developed a complication of a neuropsychiatric disease and administered corticosteroids and intravenous cyclophosphamide therapy. Her cognitive function fully recovered, and her gait disturbance improved. Attending to cognitive impairment in elderly SLE patients is necessary.

Abstract
OBJECTIVES There are no population-based estimates of the incidence or risk factors for acute cardiac manifestations in children with systemic lupus erythematosus (SLE) to guide screening and diagnostic imaging practices. We estimated the incidence and prevalence of acute cardiac manifestations of child-onset SLE compared to adult-onset SLE and identified factors associated with cardiac diagnoses. METHODS We identified children (5-17 years) and adults (18-64 years) with incident SLE (≥3 International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9 CM) code 710.0, > 30 days apart) using Clinformatics® DataMart (OptumInsight, Eden Prairie, MN) deidentified United States administrative claims (2000-2013). We calculated incidence and prevalence of three outcomes: ≥ 1 diagnosis code for (1) pericarditis and/or myocarditis, (2) endocarditis, or (3) valvular insufficiency. Negative binomial regression was used to identify characteristics associated with cardiac diagnoses in children and determine whether SLE onset in childhood vs adulthood was independently associated with cardiac involvement. RESULTS There were 297 children and 6927 adults with new-onset SLE. A total of 17.8% of children had ICD-9 CM codes for acute cardiac diagnoses, the incidence of which were highest in the first year after SLE diagnosis (12.2 per 100 person-years). African American race (incidence rate ratio (IRR) 6.6, 95% confidence interval (CI) (2.9, 15.0), p < 0.01) and nephritis (IRR 7.0, 95% CI (2.6, 18.6), p < 0.01) were associated with acute cardiac diagnoses in children. Child-onset disease was independently associated with a 4.4-fold higher rate of pericarditis or myocarditis compared to adult-onset SLE after adjustment for other disease and demographic characteristics (95% CI (2.4, 8.0), p < 0.01). CONCLUSION This study establishes baseline estimates of the incidence and prevalence of pericarditis and myocarditis in child-onset SLE, which is substantially higher than that of adult-onset SLE. Prospective echocardiographic evaluations are needed to validate incidence measures and characterize the natural history of acute cardiac manifestations in child-onset SLE, as well as identify risk factors for poor cardiac outcomes to inform screening and management.

Abstract
Rationale Late-onset systemic lupus erythematosus (SLE) represents a specific subgroup of SLE, and although there is no strict age cut-off, 50 years is commonly used as the minimum age for disease onset. In this report, we present a case of a 74-year-old male with late-onset SLE and biopsy-proven lupus nephritis (LN). Presenting concerns of the patient A 74-year-old male was referred to the nephrology clinic with a rapidly rising creatinine from a baseline of 60 µmol/L to 176 µmol/L. His labs showed pancytopenia, a positive antinuclear antibodies (ANA), and hypocomplementemia. Diagnoses Renal biopsy showed focal proliferative glomerulonephritis that was immune-mediated and immunofluorescence showed C3, IgM, IgA, IgG, lambda, and C1q diffuse mesangial and glomerular basement membrane staining. Together these findings were in keeping with a diagnosis of stage III LN. Interventions Treatment included hemodialysis and induction with pulse methylprednisone and cyclophosphamide. He was then placed on the Euro-Lupus Protocol. Outcomes One year after the diagnosis, he was off dialysis, had no signs of fluid retention or uremia, and his creatinine had stabilized at ~ 330 µmol/L. Lessons learned To the best of our knowledge, this case represents the oldest known biopsy-confirmed case of late-onset SLE and LN. Late-onset SLE is uncommon and often overlooked as classical symptoms such as malar rash or photosensitivity may not be present. The American College of Rheumatology (ACR) guidelines for treatment of LN can be applied to these patients but physicians should be cognizant of the fact that these patients may not tolerate immunosuppressive therapy as well as younger patients.

Abstract
Systemic Lupus Erythematosus (SLE) is a complex chronic autoimmune disease that manifests a wide range of organ involvement. Traditionally, the diagnosis and management of SLE is provided at secondary and tertiary centers to ensure prompt initiation of treatment, adequate control of flares and prevention of irreversible organ damage. Notwithstanding, the role of primary care in SLE is also emerging as there are still significant unmet needs such as the diagnostic delay at the community level and the high burden of therapy- and disease-related comorbidities. In the present review, we summarize practical messages for primary care physicians and general practitioners (GPs) concerning early diagnosis and proper referral of patients with SLE. In addition, we discuss the main comorbidities complicating the disease course and the recommended preventative measures, and we also provide an update on the role and current educational needs of GPs regarding the disease.

Abstract
Interferon regulatory factor 5 (IRF5) plays a critical role in the induction of type I interferon, proinflammatory cytokines and chemokines, and participates in the pathogenesis of autoimmune diseases such as systemic lupus erythematosus (SLE). However, the relationship between IRF5 and childhood-onset SLE remains elusive. In the present study, we demonstrated that levels of mRNA expression of IRF5, IFN-α, and Sp1 were significantly increased in childhood-onset SLE, as seen on quantitative real-time PCR, and the expression of Sp1 and IFN-α was positively correlated with IRF5. In addition to being used as antitumor drugs, a number of histone deacetylase inhibitors (HDACi) display potent anti-inflammatory properties; however, their effects on IRF5 expression remain unclear. In this study, we identified that HDACi trichostatin A (TSA) and histone acetyltransferase (HAT)-p300 downregulated IRF5 promoter activity, mRNA expression, and protein level, whereas the HAT-p300/CBP-associated factor had no effect. Moreover, TSA inhibited the production of TNF-α and IL-6 in differentiated THP-1cells. Furthermore, chromatin immunoprecipitation assays revealed that TSA inhibited DNA binding of Sp1, RNA polymerase II, HDAC3, and p300 to the core promoter region of IRF5. Our results suggest that HDACi may have therapeutic potential in patients with autoimmune diseases such as SLE through repression of IRF5 expression.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) affects people in childhood (childhood onset) or in adulthood (adult onset). Observational studies that have previously compared childhood-onset versus adult-onset SLE were often restricted to 1 ethnic group, or to a particular area, with a small sample size of patients. We aimed to systematically compare childhood-onset versus adult-onset SLE through a meta-analysis. METHODS Electronic databases were searched for relevant publications comparing childhood-onset with adult-onset SLE. Adverse clinical features were considered as the endpoints. The Newcastle Ottawa Scale (NOS) was used to assess the methodological quality of the studies and RevMan software (version 5.3) was used to carry out this analysis whereby risk ratios (RRs) and 95% confidence intervals (95% CIs) were used as the statistical parameters. RESULTS A total number of 10,261 participants (1560 participants with childhood-onset SLE and 8701 participants with adult-onset SLE) were enrolled. Results of this analysis showed that compared with childhood-onset SLE, pulmonary involvement was significantly higher with adult-onset SLE (RR: 1.51, 95% CI: 1.18-1.93; P = .001), whereas renal involvement was significantly higher with childhood-onset SLE (RR: 0.65, 95% CI: 0.55-0.77; P = .00001). Raynaud phenomenon and photosensitivity were significantly higher in adult-onset SLE (RR: 1.29, 95% CI: 1.04-1.60; P = .02) and (RR: 1.08, 95% CI: 1.01-1.17; P = .03), respectively. Malar rash significantly favored adult-onset SLE (RR: 0.84, 95% CI: 0.75-0.94; P = .002). Childhood-onset SLE was associated with significantly higher hemolytic anemia, thrombocytopenia, leukocytopenia, and lymphopenia. Seizure and ocular manifestations were significantly higher with childhood-onset SLE (RR: 0.57, 95% CI: 0.47-0.70; P = .00001) and (RR: 0.34, 95% CI: 0.21-0.55; P = .00001), respectively, whereas pleuritis was significantly higher with adult-onset SLE (RR: 1.45, 95% CI: 1.17-1.79; P = .0008). Vasculitis and fever were significantly higher with childhood-onset SLE (RR: 0.51, 95% CI: 0.36-0.74; P = .0004) and (RR: 0.78, 95% CI: 0.68-0.89; P = .0002) respectively. CONCLUSION Significant differences were observed between childhood-onset versus adult-onset SLE, showing the former to be more aggressive.

Abstract
Objective The objective of this paper is to investigate the clinical characteristics and prognosis of patients with late-onset systemic lupus erythematosus (SLE) using a prospective observational cohort. Methods Late-onset SLE (≥50 years old) was compared with adult-onset SLE (≥18 and <50 years old) using 1997 ACR classification criteria for SLE, autoantibodies, disease activity measured by Adjusted Mean SLE Disease Activity Index (AMS), and damage measured by Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI). The standardized mortality ratio (SMR) was calculated. Results A total of 917 patients with SLE were enrolled. The mean number of cumulative ACR criteria in late-onset SLE ( n = 32, 3.5%) was lower than that in adult-onset SLE (4.6 ± 1.2 vs. 5.5 ± 1.4, p < 0.05). The percentage of patients with low complement was lower in late-onset SLE than adult-onset SLE ( p < 0.05). AMS was also lower in late-onset SLE (2.7 ± 2.1 vs. 4.3 ± 2.6, p < 0.01), but SDI was similar between the two groups (50% vs. 43.4%, p = 0.58). The SMR of late-onset SLE was 1.58 (95% CI 0.58-3.43), while the SMR of adult-onset SLE was 3.34 (2.34-4.63). Conclusion Compared with adult-onset SLE, late-onset SLE has a lower number of ACR criteria and lower disease activity. Organ damage is not different, but prognosis and mortality are more favorable.
