Understanding the epidemiology and progression of systemic lupus erythematosus

Cardiac magnetic resonance feature tracking evaluates left atrial strain in patients with systemic lupus erythematosus and mitral regurgitation

PurposeTo explore left atrial (LA) function in patients with systemic lupus erythematosus (SLE) and mitral regurgitation assessed by cardiac magnetic resonance imaging feature tracking (MRI-FT).MethodIn this study, 64 SLE patients (35.0 ± 12.3 years, 49 females) and 50 age- and gender-matched healthy controls (32.1 ± 11.2 years, 32 females) were analyzed. Patients with SLE were further classified into two subgroups according to mitral regurgitation defined by echocardiography: mitral regurgitation subgroup (n = 32) and non-mitral regurgitation subgroup (n = 32). All subjects underwent cardiac magnetic resonance (CMR) examination and SLE patients underwent extra laboratory testing. LA volume and strain parameters were compared among the three groups, and a correlation analysis was further performed between CMR parameters and clinical variables.ResultsPatients in both mitral regurgitation and non-mitral regurgitation subgroups showed higher LAVmin (29.15 ± 7.5, 26.22 ± 8.23 vs 21.68 ± 7.67, p = .003, .026) and LAVimin (17.44,14.9 vs 12.62, p = .002,.046) than healthy control subjects. Abnormal LA reservoir, conduit and bump strain were also observed in SLE patients (all p < .05), with more severe reservoir (p = .006, .031) and bump strain (p = .01, .033) abnormality found in mitral regurgitation subgroup. In the SLE group, LA reservoir, bump and conduit strain were significantly positively correlated with LVEF (B = 0.467, p < .001 vs B = 0.019, p = .01 vs B = 0.168, p = .001 vs B = 0.036, p < .001 vs B = 0.020, p = .024). Conduit strain (εe, SRe) was positively correlated with LAEF (B = 0.229, p = .032 vs B = 0.027, p = .008).ConclusionMRI-FT based LA parameters may be considered a helpful tool to evaluate LA function in SLE patients, and LA strain may indicate severity of the cardiac dysfunction in SLE patients.

Clinical Progress in Mesenchymal Stem Cell Therapy: A Focus on Rheumatic Diseases

BACKGROUND

Rheumatic diseases are chronic immune-mediated disorders affecting multiple organ systems and significantly impairing patients' quality of life. Current treatments primarily provide symptomatic relief without offering a cure. Mesenchymal stem cells (MSCs) have emerged as a promising therapeutic option due to their ability to differentiate into various cell types and their immunomodulatory, anti-inflammatory, and regenerative properties. This review aims to summarize the clinical progress of MSC therapy in rheumatic diseases, highlight key findings from preclinical and clinical studies, and discuss challenges and future directions.

METHODOLOGY

A comprehensive review of preclinical and clinical studies on MSC therapy in rheumatic diseases, including systemic lupus erythematosus, rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, osteoporosis, Sjögren's syndrome, Crohn's disease, fibromyalgia, systemic sclerosis, dermatomyositis, and polymyositis, was conducted. Emerging strategies to enhance MSC efficacy and overcome current limitations were also analyzed.

RESULTS AND DISCUSSION

Evidence from preclinical and clinical studies suggests that MSC therapy can reduce inflammation, modulate immune responses, and promote tissue repair in various rheumatic diseases. Clinical trials have demonstrated potential benefits, including symptom relief and disease progression delay. However, challenges such as variability in treatment response, optimal cell source and dosing, long-term safety concerns, and regulatory hurdles remain significant barriers to clinical translation. Standardized protocols and further research are required to optimize MSC application.

CONCLUSION

MSC therapy holds promise for managing rheumatic diseases, offering potential disease-modifying effects beyond conventional treatments. However, large-scale, well-controlled clinical trials are essential to establish efficacy, safety, and long-term therapeutic potential. Addressing current limitations through optimized treatment protocols and regulatory frameworks will be key to its successful integration into clinical practice.

Bilateral and simultaneous retinal artery occlusion in a woman with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect almost every organ. This article describes a middle-aged woman, previously diagnosed with untreated SLE, who during a severe SLE flare simultaneously presented with a superior nasal artery occlusion in the right eye and a central retinal artery occlusion (CRAO) in the left eye. Severe ocular complications, such as CRAO, can occur during an acute flare of the disease in previously asymptomatic SLE.

GNS561 (ezurpimtrostat), a small basic lipophilic molecule, prevents lupus phenotype in a pristane-induced lupus mouse model

BACKGROUND AND PURPOSE

Systemic lupus erythematosus is an autoimmune, multisystemic disease affecting all organs in the body. Accrued evidence has elucidated a role for autophagy in the onset and severity of systemic lupus erythematosus. The antimalarial drug hydroxychloroquine constitutes the cornerstone of standard of care for systemic lupus erythematosus, together with glucocorticoids and immunosuppressants or biologics, and all accompanied by various side effects.

EXPERIMENTAL APPROACH AND OBJECTIVE

Our study aimed to investigate the potential of GNS561 (ezurpimtrostat) treatment, a small basic lipophilic molecule that induces lysosomal dysregulation, using the pristane-induced lupus mouse model.

KEY RESULTS

Compared with hydroxychloroquine, GNS561 treatment presents a more pronounced impact on the development of pathogenic anti-antibodies in pristane-induced lupus mice. Next, focussing on clinical impact, we showed that GNS561 significantly reduced clinical signs of lupus in pristane-induced lupus by preventing the incidence and severity of arthritis, occurrence of nephritis and lung damage. Finally, GNS561 modulated the inflammatory profile in pristane-induced lupus mice through a reduction of the lipogranuloma score. Interestingly, focussing on interferon-α, only pristane-induced lupus mice treated by GNS561 presented a significant decrease of the cytokine, suggesting a higher efficacy for GNS561 in the modulation of lupus-induced inflammation compared with hydroxychloroquine.

CONCLUSION

All results show that GNS561, but not hydroxychloroquine, represents as an effective treatment to prevent clinical and inflammatory signs of lupus in this mouse model.

IMPLICATIONS

Altogether, this study highlights GNS561 as a promising investigational drug for systemic lupus erythematosus.

Immunological Avalanches in Renal Immune Diseases

The complex nature of immune system behavior in both autoimmune diseases and transplant rejection can be understood through the lens of avalanche dynamics in critical-point systems. This paper introduces the concept of the "immunological avalanche" as a framework for understanding unpredictable patterns of immune activity in both contexts. Just as avalanches represent sudden releases of accumulated potential energy, immune responses exhibit periods of apparent stability followed by explosive flares triggered by seemingly minor stimuli. The model presented here draws parallels between immune system behavior and other complex systems such as earthquakes, forest fires, and neuronal activity, where localized events can propagate into large-scale disruptions. In autoimmune conditions like systemic lupus erythematosus (SLE), which affects multiple organ systems including the kidneys in approximately 50% of patients, these dynamics manifest as alternating periods of remission and flares. Similarly, in transplant recipients, the immune system exhibits metastable behavior under constant allograft stimulation. This critical-point dynamics framework is characterized by threshold-dependent activation, positive feedback loops, and dynamic non-linearity. In autoimmune diseases, triggers such as UV light exposure, infections, or stress can initiate cascading immune responses. In transplant patients, longitudinal analysis reveals how monitoring oscillatory patterns in blood parameters and biological age markers can predict rejection risk. In a preliminary study on kidney transplant, all measured variables showed temporal instability. Proteinuria exhibited precise log-log linearity in power law analysis, confirming near-critical-point system behavior. Two distinct dynamic patterns emerged: large oscillations in eGFR, proteinuria, or biological age predicted declining function, while small oscillations indicated stability. During avalanche events, biological age increased dramatically, with partial reversal leaving persistent elevation after acute episodes. Understanding these dynamics has important implications for therapeutic approaches in both contexts. Key findings suggest that monitoring parameter oscillations, rather than absolute values, better indicates system instability and potential avalanche events. Additionally, biological age calculations provide valuable prognostic information, while proteinuria measurements offer efficient sampling for system dynamics assessment. This conceptual model provides a unifying framework for understanding the pathogenesis of both autoimmune and transplant-related immune responses, potentially leading to new perspectives in disease management and rejection prediction.

Increased Sensitivity to Ionizing Radiation in a Relevant Subset of Patients with Cancer and Systemic Lupus Erythematosus

It has long been hypothesized that systemic lupus erythematosus (SLE) increases radiosensitivity, but recent studies have yielded mixed results. We studied individual radiosensitivity in 70 individuals with SLE using chromosomal aberrations as biomarkers of radiosensitivity. In total, 33 patients with SLE and 37 patients with SLE and additional oncologic diseases were compared with healthy individuals and with patients with rectal and breast cancer. Individual radiosensitivity was assessed by ex vivo irradiation of G0 blood lymphocytes followed by three-color fluorescence in situ hybridization of chromosomes 1, 2, and 4. SLE patients have slightly higher background rates of chromosomal aberrations than healthy individuals and lower rates than cancer patients. Non-oncologic SLE patients show a rate of chromosomal aberrations similar to that seen in healthy individuals. The outliers in this group, who clearly show increased radiosensitivity, fall between healthy individuals and cancer patients. Patients with SLE and cancer have significantly higher chromosome aberration rates compared to healthy individuals (p < 0.001) and patients with isolated cancer (p = 0.007) or isolated SLE (p = 0.004). The proportion of radiosensitive patients in the oncologic SLE cohort is high, with 45% of patients showing increased radiosensitivity. There is a weak association between anti-Ro-52 autoantibodies and radiosensitivity. Based on the radiosensitivity measurement, radiation dose reduction was recommended in 11 oncological SLE patients and was successfully achieved in 5 patients by up to 21% of the dose per fraction. In the oncologic SLE cohort, a substantial portion of individuals show increased radiosensitivity.

IgG glycosylation profiling of systemic lupus erythematosus using lectin microarray

OBJECTIVES

Research on the specific role of immunoglobulin G (IgG) glycosylation in SLE development and progression is limited, especially regarding changes in IgG glycosylation profiles among different SLE subtypes. In this study, we aimed to characterise the glycosylation profile of serum IgG in patients with SLE.

METHODS

Lectin microarrays with 56 lectins were used to analyse serum IgG glycosylation in 194 patients with SLE, 100 disease controls (40 primary Sjögren's syndrome (pSS), 60 rheumatoid arthritis (RA)) and 100 healthy controls (HCs). Differences between SLE and control groups, as well as SLE subgroups, were validated by lectin blotting. Altered IgG glycosylation patterns were identified and further confirmed. Receiver operating characteristic (ROC) analysis evaluated the diagnostic value of these glycosylation changes in SLE and its subgroups, including neuropsychiatric SLE (NPSLE), lupus nephritis (LN), pulmonary arterial hypertension, immune thrombocytopaenia and SLE without major organ involvement (WMOI).

RESULTS

Compared to DC and HC groups, the IgG glycan level of Galβ3GalNAc (binding Jacalin (11.3%) and Maclura pomifera lectin (14.4%)) was significantly increased, whereas most IgG glycan levels were significantly decreased, including core fucose, high mannose, GlcNAc, GalNAc and Galβ4GlcNAc in the SLE group (all p<0.05).The IgG glycan levels were elevated in GalNAc and galactose patterns in the NPSLE group compared to the WMOI group, as well as higher Galβ3GalNAc and galactose patterns in NPSLE and LN compared to HCs.Moreover, ROC curve analysis showed PNA levels might have moderate potential for discriminating SLE from pSS.

CONCLUSIONS

Patients with SLE show disease-specific alterations in serum IgG glycosylation, and aberrant Galβ3GalNAc, galactose and GalNAc glycosylation may have diagnostic value for SLE and NPSLE. Abnormal IgG glycans may provide new insights into their roles in SLE pathogenesis and progression.

2025 SWHR Women's Health Research Agenda: Prioritizing Uterine Fibroids, Lupus, and Metabolism

Women face unique and multifaceted challenges throughout their lifespans, shaped by biological, societal, and health care-related factors. These challenges have led to gender disparities in disease burden, access to care, and representation in medical research, underscoring the need to increase targeted investments in women's health. Historically, research on diseases that disproportionately affect women has been underfunded, hindering progress in closing gender health gaps. In March 2024, the President of the United States signed an Executive Order on Women's Health Research and Innovation, signaling a new commitment by the federal government to prioritize women's health research and address these disparities. The Society for Women's Health Research (SWHR) has consistently led the charge to identify research gaps and advocate for evidence-based initiatives to improve the health and well-being of women. In celebration of its 35th anniversary, SWHR introduces a 2025 Women's Health Research Agenda, which outlines key priorities in the areas of uterine health, autoimmune disease, and cardiometabolic health. This agenda serves as a strategic roadmap for stakeholders to engage with critical areas of women's health, fostering collaboration and accelerating research to address the unmet needs of women across the lifespan.

Outcomes following total shoulder arthroplasty in patients with systemic lupus erythematosus

BACKGROUND

Total shoulder arthroplasty (TSA) is a common procedure that may be considered for patients with glenohumeral osteoarthritis. Patients undergoing this procedure may be afflicted by comorbid conditions, such as systemic lupus erythematosus (SLE), which may impact odds of various postoperative complications.

METHODS

Adult patients with and without SLE who underwent TSA (anatomic or reverse) were queried from the January 2010 to October 2022 PearlDiver M165 database. Patients with and without SLE were matched (1:4) based on age, sex, and Elixhauser Comorbidity Index. Ninety-day adverse events and 5-year implant survival were assessed and compared with multivariable analysis. Subanalyses were done for SLE patients with and without a prescription of immunomodulatory therapy (IMT; corticosteroids, hydroxychloroquine, and/or biologics) within 90 days before surgery and compared to non-SLE patients with multivariable analyses. Lastly, SLE patients with and without a 90-day history of IMT were directly compared with multivariate logistic regression. A Bonferroni correction was applied to univariable analyses and multivariable regressions.

RESULTS

Of 211,832 TSA patients identified, SLE was noted for 2228 (1.1%). After matching, 8261 patients without SLE and 2085 patients with SLE were selected. SLE patients were at an increased odds of 90-day aggregated events including severe (odds ratio [OR] = 3.50), minor (OR = 3.13), all (OR = 2.35), and orthopedic-related (OR = 1.41) adverse events (P < .0030 for all). There was no difference in 5-year implant survival. Of those with SLE, IMT medications were being received by 1267 (60.8%). Any, severe, minor, and orthopedic 90-day adverse events were significantly elevated for both those with and without IMT relative to those without SLE (P < .0030 for all except for orthopedic adverse events for those not on IMT, which were not significant). Relative to those not on IMT medications, those on IMT medications were at significantly higher odds of any, severe, minor, and orthopedic adverse events.

CONCLUSION

Following TSA, patients with SLE were found to be at an increased odds of 90-day adverse events but not of 5-year revisions. Furthermore, those on IMT medications were at higher risk of any, severe, minor, and orthopedic adverse events compared to those who were not on these medications. These findings may help with patient counseling and surgical planning when those with SLE are considered for TSA.

Systemic lupus erythematosus: updated insights on the pathogenesis, diagnosis, prevention and therapeutics

Systemic lupus erythematosus (SLE) is a chronic inflammatory illness with heterogeneous clinical manifestations covering multiple organs. Diversified types of medications have been shown effective for alleviating SLE syndromes, ranging from cytokines, antibodies, hormones, molecular inhibitors or antagonists, to cell transfusion. Drugs developed for treating other diseases may benefit SLE patients, and agents established as SLE therapeutics may be SLE-inductive. Complexities regarding SLE therapeutics render it essential and urgent to identify the mechanisms-of-action and pivotal signaling axis driving SLE pathogenesis, and to establish innovative SLE-targeting approaches with desirable therapeutic outcome and safety. After introducing the research history of SLE and its epidemiology, we categorized primary determinants driving SLE pathogenesis by their mechanisms; combed through current knowledge on SLE diagnosis and grouped them by disease onset, activity and comorbidity; introduced the genetic, epigenetic, hormonal and environmental factors predisposing SLE; and comprehensively categorized preventive strategies and available SLE therapeutics according to their functioning mechanisms. In summary, we proposed three mechanisms with determinant roles on SLE initiation and progression, i.e., attenuating the immune system, restoring the cytokine microenvironment homeostasis, and rescuing the impaired debris clearance machinery; and provided updated insights on current understandings of SLE regarding its pathogenesis, diagnosis, prevention and therapeutics, which may open an innovative avenue in the fields of SLE management.

Precision Medicine in Rheumatology: The Role of Biomarkers in Diagnosis and Treatment Optimization

Rheumatic diseases encompass a wide range of autoimmune and inflammatory disorders, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), psoriatic arthritis (PsA), and systemic sclerosis (SSc). These conditions often result in chronic pain, disability, and reduced quality of life, with unpredictable disease courses that may lead to joint destruction, organ damage, or systemic complications. Biomarkers, defined as measurable indicators of biological processes or conditions, have the potential to transform clinical practice by improving disease diagnosis, monitoring, prognosis, and treatment decisions. While significant strides have been made in identifying and validating biomarkers in rheumatic diseases, challenges remain in their standardization, clinical utility, and integration into routine practice. This review provides an overview of the current state of biomarkers in rheumatic diseases, their roles in clinical settings, and the emerging advancements in the field.

Lifetime clinical presentation of Still's disease in the Afro-descendant population of the French West Indies

INTRODUCTION

The continuum in Still's disease has never been addressed in Afro-descendant (AD) populations. The aim of this study was to compare the features of Still's disease between children and adults in the AD population of French West Indies (FWI).

METHODS

Retrospective longitudinal study from January 2000-2022. We included children and adults with systemic juvenile idiopathic arthritis and Still's disease. Clinical data were obtained from computerized hospital archives, registries of clinicians and the national registry for rare diseases. The main outcome was similarity in cardinal and non-cardinal symptoms.

RESULTS

Fifty-eight patients were included (57% adults). Sex distribution between children and adults was significantly different (Female respectively 36% vs 70.6%, P=0.03). Diagnostic criteria overlapped in most cases (80%), regardless of age. The children had significantly more typical skin rashes (100% vs 29.4%, P<0.001), coronary artery dilation (16% vs 0%, P=0.03), and macrophage activation syndrome (52% vs 9%, P<0.001). The adults had significantly more inflammatory polyarthalgia without arthritis (91% vs 32% P<0.001) and pulmonary involvement (51.5% vs 4% P<0.001). The phenotypes were 86% systemic (43% monophasic, 43% polycyclic) and 14% chronic polyarticular. No difference was found in the number of relapses, use of biologics and mortality.

CONCLUSIONS

There is a rationale for considering Still's disease as a single entity in our AD population, focusing on the cardinal symptoms, but particular attention should be paid to the non-cardinal symptoms depending on the age of onset.

Analysis of expression and its clinical significance of the ADAMTS-2 in systemic lupus erythematosus

OBJECTIVES

ADAMTS-2 is a procollagen N-proteinase that plays an important role in inflammation regulation. The objective of our research is to explore the expression of ADAMTS-2 in Systemic Lupus Erythematosus (SLE), and analyze its relationship with clinical features of SLE, and evaluate the potential value of ADAMTS-2 as a diagnostic biomarker in SLE.

METHODS

ADAMTS-2 expression in PBMCs was detected by RT-qPCR in SLE patients, RA patients, and healthy controls (HC). The diagnostic value of ADAMTS-2 for SLE was evaluated by ROC curve, and the correlation between ADAMTS-2 and the clinical characteristics of SLE was analyzed by Spearman's rank correlation coefficient. The expression profiles of GSE8650 and GSE82221 were downloaded from the GEO database. We performed GSEA to further understand the functions of ADAMTS-2 in SLE. CIBERSORT was utilized for immune cell infiltration analysis.

RESULTS

RT-qPCR results validated that the expression of ADAMTS-2 in PBMCs was significantly increased in SLE patients than RA patients and HC. ROC anaylsis suggested that ADAMTS-2 has significant value in distinguishing new-onset SLE patients from RA patients and HC (AUC = 0.805, p < 0.0001). The expression of ADAMTS-2 was negatively correlated with C3, WBC, PLT, neutrophil, and monocyte level. PBMCs samples with high ADAMTS-2 expression were enriched in TNFA_SIGNALING_VIA_NFKB pathway. We found that ADAMTS-2 was positively correlated with neutrophils, M0 macrophages and M2 macrophages.

CONCLUSION

ADAMTS-2 may be a potential biomarker of SLE patients and closely related to the occurrence and development of SLE. ADAMTS-2 is expected to be a new target for SLE treatment. Key Points • ADAMTS-2 is a potential biomarker of disease activity in SLE patients that develop a flare. • Samples with high ADAMTS-2 expression are enriched in TNFA_SIGNALING_VIA_NFKB pathway in SLE. • ADAMTS-2 expression is positively correlated with neutrophils, M0 macrophages and M2 macrophages.

Training to Increase Minority Enrollment in Lupus Clinical Trials With Community Engagement: Enhancing Lupus Clinical Trial Recruitment Through Provider and Community Health Worker Engagement

OBJECTIVE

This study evaluates the effectiveness of the Training to Increase Minority Enrollment in Lupus Clinical Trials with Community Engagement (TIMELY) program on enhancing referrals of underrepresented patients to lupus clinical trials. TIMELY leverages two existing American College of Rheumatology online educational initiatives: Materials to Increase Minority Involvement in Clinical Trials (MIMICT), a continuing medical education activity for health care providers, and the community health worker (CHW) Lupus Clinical Trials Training (LuCTT). TIMELY introduced a unique roundtable meeting format to build on the existing online educational programs and facilitate discussions between local clinical trial sites and provider and CHW participants.

METHODS

This study used an online pretest and posttest design to assess changes in theory-based behavioral predictors of lupus clinical trial referrals and engagement (ie, knowledge, attitudes, self-efficacy, and intentions) among providers and CHWs. Participants completed MIMICT or LuCTT and then were eligible to participate in roundtable meetings. Paired t-tests were used to assess changes in composite scores before and after the intervention for each of the outcomes.

RESULTS

The final sample included 40 providers and 18 CHWs. Knowledge scores increased significantly for both providers (P < 0.01) and CHWs (P < 0.001) on completion of MIMICT and LuCTT, respectively. After participating in the TIMELY roundtable, providers' composite scores for self-efficacy and intentions significantly increased (P < 0.001). Provider self-efficacy gains were sustained at three months' follow-up (P < 0.001).

CONCLUSION

These promising findings highlight the potential and opportunities for the TIMELY program to improve behavioral predictors of trial referrals, including CHW knowledge and providers' knowledge, self-efficacy, and intentions to refer underrepresented patients to lupus clinical trials.

Changes of Peripheral T Cells in Systemic Lupus Erythematosus Patients

BACKGROUND

Efficient indicators for evaluating the imbalance of lymphocyte function were crucial to clinical therapy in systemic lupus erythematosus (SLE) patients. This study aimed to find biomarkers to assess lymphocyte-mediated immune response in SLE patients.

METHODS

A total of 81 SLE patients (non-active: n = 35, active: n = 46) and 70 healthy donors were recruited in the study. Peripheral blood was obtained, and flow cytometry was used to detect circulating lymphocytes.

RESULTS

Data showed that the counts of CD3+T, CD4+T, CD8+ T, and NK cells were decreased in active SLE patients compared with non-active SLE patients and healthy donors. The counts of peripheral T cells were increased in responders but decreased in non-responders among active patients. In addition, an increase in B cell counts was found in active SLE patients compared with those in the other two groups. Active SLE patients showed higher percentages of memory T cells but lower naive T cells than those in non-active SLE patients and healthy controls. Activation molecules (CD38 and HLA-DR) and inhibitory molecule PD-1 expressions on T cells were significantly higher but percentages of CD28+CD8+T cells were lower in active SLE patients compared with those in the other two groups.

CONCLUSION

This study indicated that monitoring the alterations of circulating lymphocyte counts and surface molecules may be helpful to assess disease activity of SLE patients, even discriminate active and non-active patients, which was beneficial to choose the best treatment option in clinical therapy.

A Case of Lupus Myopericarditis in a Young African American Male

A 28-year-old African American male presented to the emergency department with a chief complaint of chest pain. He stated that the pain began five days prior to arrival and had not improved despite taking ibuprofen and self-medicating with marijuana. His chest pain was constant and localized to the center of his chest, rating it as a 7/10 in terms of severity. His past medical history included a diagnosis of systemic lupus erythematosus (SLE) three months ago, complicated by pericarditis, for which he had been taking colchicine and prednisone, as well as hydroxychloroquine for maintenance therapy. He stated that he adhered to his treatment regimen without missing a single dosage. Upon cardiac auscultation, he was found to have a pericardial friction rub. His ECG showed signs of PR-segment depression in all leads, ST-elevation in leads V2-V4, as well as sinus tachycardia, raising some concern for myocardial ischemia. His echocardiogram showed no signs of pericardial effusion or left ventricular dysfunction and was otherwise unremarkable. Because of his positional chest pain, diffuse ST-elevation, and elevated troponin, the patient was diagnosed with myopericarditis, thought to be secondary to SLE exacerbation due to no recent illnesses. He was then placed on low-dose prednisone. After four days, his symptoms resolved, and he was discharged with a regimen of 60 mg prednisone daily and 0.5 mg colchicine daily for his pericarditis as well as 10 mg oxycodone for his pain every eight hours. His prednisone was to be tapered with a rheumatologist outpatient, but there was no follow-up at the time of writing this study.

Real-world treatment patterns and clinical characteristics in patients with moderate-to-severe systemic lupus erythematosus: an analysis of the SLE Prospective Observational Cohort Study (SPOCS)

OBJECTIVES

Systemic lupus erythematosus (SLE) is a disease with heterogeneous treatment patterns largely based on organ involvement and disease severity. The SLE Prospective Observational Cohort Study (SPOCS) collected data worldwide over 3 years from patients with moderate-to-severe SLE. We report real-world patterns of medication use in patients enrolled in SPOCS.

METHODS

Data were collected at study entry; patients were followed twice annually according to local practice. Disease activity (SLE Disease Activity Index 2000 (SLEDAI-2K)), average oral glucocorticoid dose and use of other treatments-specifically antimalarials, biologics and immunosuppressants-were measured over time. Subgroup analyses were stratified by baseline interferon gene signature (IFNGS) status and disease activity (SLEDAI-2K) status.

RESULTS

Patient demographics and baseline characteristics were similar among subgroups; the majority of patients were on antimalarials (n=670; 81.1%), followed by glucocorticoids (n=537; 65.0%), immunosuppressants (n=453; 54.8%) and biologics (n=175; 21.2%). In the overall population, median (IQR) SLEDAI-2K scores decreased within 12 months (baseline: 8.0 (6.0-12.0); 12 months: 4.0 (2.0-8.0)) and remained stable thereafter. The mean (SD) daily oral glucocorticoid dose increased by 6 months (baseline: 6.0 (7.09); 6 months: 9.8 (8.67)) and remained stable thereafter. The proportion of patients who were on glucocorticoid doses >5 mg/day ranged from ~20% to 33% throughout the study. In subgroup analyses, patients with high IFNGS and high disease activity state (HDAS) at baseline used more immunosuppressants and glucocorticoids compared with those with low IFNGS and non-HDAS at baseline.

CONCLUSIONS

These findings underscore that SLE therapy is still often unable to reach goals as recommended by the European Alliance of Associations for Rheumatology, both with regard to glucocorticoid use and disease activity, suggesting that there is an unmet need for new treatment options for patients with SLE.

Longitudinal associations of flare and damage accrual in patients with systemic lupus erythematosus

OBJECTIVE

To estimate the prevalence of organ damage (damage) and flare and to examine longitudinal associations between flares and subsequent damage accrual, in patients with systemic lupus erythematosus (SLE).

METHODS

Patients enrolled in the Asia Pacific Lupus Collaboration cohort with ≥3 years of prospectively captured data were studied. Flares were assessed at routine visits, while damage ((Systemic Lupus International Collaborating Clinics/American College of Rheumatology) Damage Index) was assessed annually. Multivariable, multifailure survival analyses were carried out to quantify the association between flares and damage accrual.

RESULTS

1556 patients with SLE with a median (IQR) of 5.7 (3.9, 7.0) years of follow-up were studied. 39.5% (n=614) of patients had damage at enrolment, and 31.9% (n=496) accrued damage during the study observation period. The incidence of damage accrual during observation was ~58/1000 person-years. Overall, 74.1% (n=1153) of patients experienced a flare of any severity (mild/moderate or severe) at least once; 56.9% (n=885) experienced recurrent (≥2) flares. The risk of subsequent damage accrual in patients who experienced mild-to-moderate flare, after controlling for confounders, was 32% greater than in patients without flares (adjusted HR) (95% CI 1.32 (1.17 to 1.72)). The risk of damage accrual was greater if patients had severe flares (HR (95% CI) 1.58 (1.18 to 2.11)). For each additional flare, the risk of damage accrual increased by 7% (HR (95% CI) 1.07 (1.02 to 1.13)).

CONCLUSIONS

Flares independently increased the risk of damage accrual. Prevention of flares should be considered a necessary goal of SLE disease management to minimise permanent damage.

Systemic lupus erythematosus is associated with an increased risk of cervical artery dissection

Limited evidence suggests that autoimmune diseases are associated with an increased risk of cervical artery dissection (CeAD). We hypothesized individuals with systemic lupus erythematosus (SLE) would have an increased risk of CeAD following SLE diagnosis compared to matched non-lupus controls. We queried a de-identified United States electronic medical records network (TriNetX, Inc.) for individuals aged 10 and older from 2012 to 2020, for two cohorts: (1) SLE and (2) non-lupus controls, excluding those with prior CeAD. We used propensity matching to control for confounding variables and calculated the risk ratio (RR) for CeAD occurring over four years' follow-up, secondarily exploring cumulative incidence. After matching, both cohorts contained 77,008 patients, who were mostly female (89%). The incidence and risk of CeAD was significantly greater among those with SLE compared to matched non-lupus controls [95% CI] (0.08% vs. 0.04%; RR = 2.33 [1.49;3.66]; P < 0.0001). These findings support the hypothesis that SLE is a risk factor for CeAD. Additional research is needed to identify the mechanisms that may underly the SLE-CeAD association and examine the potential association between other autoimmune diseases and CeAD.

Exploring genetic associations in systemic lupus erythematosus through Mendelian randomization: implications for novel biomarkers and therapeutic targets

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by a significant health burden. There is an essential need for novel biomarkers and therapeutic targets to improve diagnosis and management. Mendelian randomization (MR) was applied to explore causal links between SLE and various biomarkers like immune cells, metabolites, and inflammatory cytokines using multiple databases. Initially, biomarkers significantly associated with SLE were identified. Bidirectional MR helped clarify these relationships, and a two-step mediation MR examined their effects on SLE risk. Intersection analysis was used to identify biomarkers with consistent effects across datasets. Four biomarkers were identified as having significant associations with SLE risk: 1-palmitoyl-2-arachidonoyl-GPI levels [odds ratio (OR), 1.379; 95% confidence interval (CI), 1.180 to 1.613; FDR, 0.046], IL-17A levels (OR, 2.197; 95% CI, 1.412 to 3.418; FDR, 0.044), N-acetyl-aspartyl-glutamate (NAAG) levels (OR, 0.882; 95% CI, 0.831 to 0.936; FDR, 0.030), and ribitol levels (OR, 0.743; 95% CI, 0.644 to 0.857; FDR, 0.012). Bidirectional MR showed an inverse effect of NAAG on IL-17A levels (OR, 0.978; 95% CI, 0.962 to 0.994; p = 0.006). Mediation analysis indicated that NAAG influenced SLE risk both directly (beta =  - 0.108) and indirectly through IL-17A (beta =  - 0.018), highlighting the potential mediating role of IL-17A. After expanding the significance criteria to p < 0.05, intersection analysis across multiple datasets revealed 29 biomarkers with consistent beta directions, including 19 potential risk factors (beta > 0) and 10 protective factors (beta < 0) for SLE. This research has revealed significant genetic associations with SLE and demonstrated that IL-17A mediates the relationship between NAAG levels and SLE risk, highlighting potential new targets for personalized therapeutic interventions. Key Points • This study employs MR to identify significant genetic associations between various biomarkers and SLE, providing novel insights into potential biomarkers and therapeutic targets. • Four key biomarkers were identified as significantly associated with SLE risk: 1-palmitoyl-2-arachidonoyl-GPI, IL-17A, N-acetyl-aspartyl-glutamate (NAAG), and ribitol. • The findings suggest that NAAG levels have a protective effect against SLE, partly mediated through IL-17A, indicating a complex interplay between these biomarkers in the pathogenesis of SLE. • Intersectional analysis across multiple datasets revealed 29 biomarkers with consistent effects on SLE risk, highlighting new directions for future research and potential personalized therapeutic strategies.

The 100 top-cited studies in systemic lupus erythematosus: A bibliometric analysis

Systemic lupus erythematosus (SLE) is an autoimmune inflammatory tissue disease. In view of the explosive growth in research on SLE, bibliometrics was performed to evaluate the 100 top-cited papers in this realm. We performed the search with terms "systemic lupus erythematosus" the Web of Science Core Collection database on May 3, 2023. Relevant literatures were screened. Data were extracted and analyzed by SPSS. The citations of 100 top-cited SLE studies spanned from 472 to 13,557. Most studies (60 out of 100) were conducted in the United States. Total citation times were positively associated with ACY, which was negatively correlated with the length of time since publication. Approximately half of the studies focused on the underlying mechanisms of SLE. New biologic therapies garnered attention and development. Our findings provide valuable insights into the developments in crucial areas of SLE and shed contributions to future studies.

Temporal trends in mortality in patients with systemic lupus erythematosus: a Danish population-based matched cohort study

OBJECTIVE

Excess mortality has been demonstrated in patients with SLE compared with the general population. We aimed to investigate the 5-year and 10-year all-cause mortality in patients with SLE compared with the general population in recent decades.

METHODS

This was a Danish nationwide population-based exposure-matched cohort study. Incident cases of SLE diagnosed between 1996 and 2015 were identified using administrative health registries and followed until 2020, allowing for 5 and 10 years of follow-up. Patients with SLE were matched 1:5 on age and sex with individuals from the Danish general population. Time-to-event analyses were performed using the pseudo-observation approach.

RESULTS

In total, 1351 incident cases of SLE and 6755 matched controls were identified. The crude risk difference (RD) for 5-year mortality decreased over the study period, from 10.3% (95% CI 6.5-14.1%) to 4.6% (95% CI 1.4-7.8%) for patients with SLE compared with controls. The relative risk (RR) for 5-year mortality decreased similarly in the same period. Adjustment for comorbidities revealed lower RD and RR for mortality in patients with SLE compared with controls, but the decreasing trend remained. The crude and adjusted RD and RR for 10-year mortality did not change over the calendar period. The 10-year RR was highest in young patients with SLE (<50 years of age).

CONCLUSION

The 5-year mortality risk decreased over time for both patients with SLE and matched controls. However, excess 5-year mortality for patients with SLE in the most recent calendar period and excess mortality late in their disease course remained. Continued focus on preventing disease progression and comorbidity is required.

A Comprehensive Review of Low-Dose Interleukin-2 (IL-2) Therapy for Systemic Lupus Erythematosus: Mechanisms, Efficacy, and Clinical Applications

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that causes extensive inflammation and tissue destruction across several organs. Conventional therapies, such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and immunosuppressive drugs, can have serious adverse effects and are not always successful. This study looks at the possibility of low-dose interleukin-2 (IL-2) therapy as a new treatment for SLE, focusing on its mechanics, effectiveness, and clinical applicability. Low-dose IL-2 treatment selectively increases and activates regulatory T cells (Tregs), which are essential for immunological tolerance but are often lacking in SLE patients. Unlike standard medicines, which widely inhibit the immune system, low-dose IL-2 provides a more tailored approach with fewer side effects. We examined preclinical and clinical research and discovered that low-dose IL-2 dramatically enhances Treg numbers and function, lowers disease activity, and improves clinical outcomes. The primary molecular processes include the stimulation of the Janus kinase - signal transducer of activators of transcription (JAK-STAT), phosphatidylinositol 3-kinase - protein kinase B (PI3K-Akt), and mitogen‑activated protein kinase (MAPK) pathways, which enhance Treg proliferation, survival, and activity. A thorough review of clinical studies finds that low-dose IL-2 treatment is well-tolerated and effective, with fewer side effects than biologics like belimumab and rituximab. Furthermore, IL-2 therapy provides prospects for combination therapies, which may improve therapeutic success by addressing numerous components of the immune response. Despite these encouraging findings, problems such as patient response variability and the need for long-term safety data persist. Future research should prioritize refining dose regimes, discovering biomarkers for patient selection, and investigating combination medicines. Addressing these issues might solidify low-dose IL-2 treatment as a cornerstone in SLE care, providing a more accurate and individualized approach to immune regulation while considerably improving patient outcomes.

E-Health Interventions to Improve Health Outcomes in Patients with Systemic Lupus Erythematosus: A Systematic Review

BACKGROUND

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease that involves damage to one or more organs and systems. E-Health technologies have been used to improve the quality of care and to minimize the cost of rehabilitation services. This study aimed to provide the most recent and convincing evidence on the rehabilitation effects of e-Health interventions compared to conventional treatments.

METHODS

A systematic review was conducted. Inclusion criteria were defined following PICO recommendations (i.e., populations, intervention, comparison and outcome measures). Methodological quality and risk-of-bias were assessed for each study.

RESULTS

Six studies met the inclusion criteria, providing data on 743 individuals with SLE. Results indicated that e-Health interventions improved health outcomes, such as disease management or emotional status. Methodological quality was moderate and low risk-of-bias was found in the majority of the studies included.

CONCLUSIONS

For patients with SLE, e-Health interventions are a safe rehabilitation intervention to improve health outcomes. However, more high-quality studies with large samples are needed, with a focus on the long-term outcomes of e-Health interventions for patients with SLE.

Evaluation of the incidence of melanoma and non-melanoma skin cancer in patients with systemic lupus erythematosus and systemic sclerosis

BACKGROUND

The incidence of skin cancer in patients with systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) has only been investigated with retrospective studies enrolling a low number of patients. The aims of our study were to assess the incidence of skin cancer in two large cohorts of patients, one with SLE and the other with SSc and investigating possible risk factors.

METHODS

Ninety SLE, 53 SSc patients and 392 control subjects were enrolled. A questionnaire including personal and medical details was fulfilled. The severity of photoaging, photosensitivity and sun exposure habits was assessed. Skin lesions were evaluated using a video-dermatoscope. Suspicious lesions were surgically removed.

RESULTS

The incidence of skin cancer was not different to those of controls. However, a decrease in the incidence of basal cell carcinoma was found in patients with SLE. This finding associated negatively with photosensitivity. SSc patients with skin malignancies did not report photosensitivity and did not adopt a careful photoprotection. A positive association was found between skin cancer and diffuse cutaneous sclerosis, pitting scars, severe photoaging and treatment with Iloprost.

CONCLUSIONS

Regular avoidance of sun exposure and photoprotection are effective in reducing the development of skin cancer in patients with autoimmune diseases.

Impact of intimate partner violence on quality of life and disease activity in women with systemic lupus erythematosus

OBJECTIVE

Stress and trauma are psychosocial factors with an impact on the course of systemic lupus erythematosus (SLE). The influence of violence on SLE has not been entirely explored, even though women (including patients with rheumatic diseases) are a vulnerable population to any form of violence. This study aims to assess the prevalence and impact of intimate partner violence (IPV) on health-related quality of life in women with SLE.

METHODS

An observational, cross-sectional, and analytical study was conducted at a rheumatology clinic of a university hospital from September 2022 and September 2023. We evaluated the presence of IPV in 85 women with SLE with the Hurt, Insulted, Threatened with Harm and Screamed at (HITS) questionnaire and the Index of Spouse Abuse (ISA), and quality of life with LupusQoL.

RESULTS

The prevalence by HITS score of past-year IPV was 24.4% and of lifetime IPV was 36.5%. Past-year non-physical violence was present in 17.1% of patients by ISA, and 27.1% were victims in their lifetime. While in physical violence, 7.3% were victims in the previous year and 21.2% in their lifetime. The total quality of life and the emotional domain by LupusQoL were diminished in victims of past-year IPV, compared to those who weren't exposed (p = .018 and p = .036, respectively). Past-year HITS score correlated with the Physician Global Assessment (PGA) (rho = 0.301, p = .006), while lifetime HITS score correlated with PGA (rho = 0.329, p = .002) and SLEDAI-2K (rho = 0.277, p = .010).

CONCLUSION

We found that one in four women suffered IPV in the previous year, and those who were exposed had diminished quality of life. Also, the severity of the abuse correlated with disease activity. Our findings emphasize the importance of comprehensive care for patients with SLE.

Curcumin attenuates lupus nephritis by inhibiting neutrophil migration via PI3K/AKT/NF-κB signalling pathway

OBJECTIVE

To investigate the role of curcumin in the treatment of lupus nephritis (LN) by inhibiting the migration of neutrophils and the underlying mechanism involved.

METHODS

Two lupus mouse models, MRL/lpr mice and R848-treated mice, were treated with 50 mg/kg curcumin by intraperitoneal injection. H&E and Masson staining were used to estimate histopathological changes in the kidney. Immunofluorescence was used to assess the deposition of immune complexes. The expression of inflammatory factors was detected by enzyme-linked immunosorbent assay (ELISA) and real-time reverse transcription polymerase reaction (RT-PCR), and the protein expression was detected by western blotting.

RESULTS

We revealed the remarkable potential of curcumin in improving inflammatory conditions in both MRL/lpr mice and R848-induced lupus mice. Curcumin effectively decelerates the progression of inflammation and diminishes the infiltration of neutrophils and their release of pivotal inflammatory factors, thereby reducing inflammation in renal tissues. Mechanistically, curcumin significantly inhibits the expression of p-PI3K, p-AKT and p-NF-κB, which are upregulated by interleukin-8 to induce neutrophil migration and renal inflammation, thereby reducing neutrophil migration and the release of inflammatory factors.

CONCLUSION

Curcumin significantly inhibits the recruitment of neutrophils and the release of proinflammatory factors in the kidney by inhibiting the PI3K/AKT/NF-κB signalling pathway, providing new therapeutic targets and medication strategies for the treatment of LN.

[What is proven in the treatment of systemic lupus erythematosus?]

Systemic lupus erythematosus (SLE) is an autoimmune disease with variable clinical presentation and organ involvement. Early diagnosis and rapid achievement of low disease activity or remission reduces organ damage and improves prognosis. Therapeutic principles can be divided into so-called basic measures and immunosuppressive treatment. Novel drugs have been developed in recent years, with new classes of agents being added for the treatment of SLE. These include biologic therapies and approved therapeutic options for the treatment of lupus nephritis. In light of improved treatment options, good disease control can now frequently be achieved; with savings on glucocorticoids, combination therapies are increasingly being used. Of great importance is the consistent use of basic measures, which include the use of hydroxychloroquine, optimization of cardiovascular risk factors, UV protection, bone-protective measures, and the implementation of vaccinations. In the treatment of lupus nephritis, conservative therapeutic measures for nephroprotection play a crucial role in renal prognosis. Finally, non-pharmacological therapy options such as exercise therapy are of great importance for improving quality of life.

Receipt of rheumatology care and lupus-specific labs among young adults with systemic lupus erythematosus: A US Medicare retention in care cohort study

OBJECTIVE

In systemic lupus erythematosus, poor disease outcomes occur in young adults, patients identifying as Black or Hispanic, and socioeconomically disadvantaged patients. These identities and social factors differentially shape care access and quality that contribute to lupus health disparities in the US. Thus, our objective was to measure markers of care access and quality, including rheumatology visits (longitudinal care retention) and lupus-specific serology testing, by race and ethnicity, neighborhood disadvantage, and geographic context.

METHODS

This cohort study used a geo-linked 20% national sample of young adult Medicare beneficiaries (ages 18-35) with lupus-coded encounters and a 1-year assessment period. Retention in lupus care required a rheumatology visit in each 6-month period, and serology testing required ≥1 complement or dsDNA antibody test within the year. Multivariable logistic regression models were fit for visit-based retention and serology testing to determine associations with race and ethnicity, neighborhood disadvantage, and geography.

RESULTS

Among 1,036 young adults with lupus, 39% saw a rheumatologist every 6 months and 28% had serology testing. White beneficiaries from the least disadvantaged quintile of neighborhoods had higher visit-based retention than other beneficiaries (64% vs 30%-60%). Serology testing decreased with increasing neighborhood disadvantage quintile (aOR 0.80; 95% CI 0.71, 0.90) and in the Midwest (aOR 0.46; 0.30, 0.71).

CONCLUSION

Disparities in care, measured by rheumatology visits and serology testing, exist by neighborhood disadvantage, race and ethnicity, and region among young adults with lupus, despite uniform Medicare coverage. Findings support evaluating lupus care quality measures and their impact on US lupus outcomes.

The dualistic role of Lyn tyrosine kinase in immune cell signaling: implications for systemic lupus erythematosus

Systemic lupus erythematosus (SLE, lupus) is a debilitating, multisystem autoimmune disease that can affect any organ in the body. The disease is characterized by circulating autoantibodies that accumulate in organs and tissues, which triggers an inflammatory response that can cause permanent damage leading to significant morbidity and mortality. Lyn, a member of the Src family of non-receptor protein tyrosine kinases, is highly implicated in SLE as remarkably both mice lacking Lyn or expressing a gain-of-function mutation in Lyn develop spontaneous lupus-like disease due to altered signaling in B lymphocytes and myeloid cells, suggesting its expression or activation state plays a critical role in maintaining tolerance. The past 30 years of research has begun to elucidate the role of Lyn in a duplicitous signaling network of activating and inhibitory immunoreceptors and related targets, including interactions with the interferon regulatory factor family in the toll-like receptor pathway. Gain-of-function mutations in Lyn have now been identified in human cases and like mouse models, cause severe systemic autoinflammation. Studies of Lyn in SLE patients have presented mixed findings, which may reflect the heterogeneity of disease processes in SLE, with impairment or enhancement in Lyn function affecting subsets of SLE patients that may be a means of stratification. In this review, we present an overview of the phosphorylation and protein-binding targets of Lyn in B lymphocytes and myeloid cells, highlighting the structural domains of the protein that are involved in its function, and provide an update on studies of Lyn in SLE patients.

A Rare Cause of Pancytopenia in Systemic Lupus Erythematosus (SLE) in a Young Patient

Systemic lupus erythematosus (SLE) is an autoimmune condition characterized by antibodies targeting nuclear and cytoplasmic antigens. It can present with diverse clinical symptoms, including pancytopenia. We present the case of an African American woman in her 20s, with a history of SLE who presented with bruising on her body. She had been receiving treatment with hydroxychloroquine, mycophenolate, prednisone, and lisinopril. During a follow-up visit, her workup revealed pancytopenia, prompting an investigation for causes. A flare-up of underlying SLE or mycophenolate toxicity was the likely culprit. However, the clinical picture was not aligned with either. A bone marrow biopsy ultimately led to the diagnosis of acute promyelocytic leukemia. The incidence of acute promyelocytic leukemia following SLE is exceedingly rare. Hence, it could present a significant diagnostic dilemma in patients with pancytopenia and underlying SLE.

Investigating the causal association between systemic lupus erythematosus and migraine using Mendelian randomization analysis

OBJECTIVE

To assess whether systemic lupus erythematosus (SLE) may be genetically causally associated with migraine, including the two primary subtypes: migraine with aura (MWA) and migraine without aura (MWoA).

BACKGROUND

The association between SLE and migraine has been investigated extensively. Previous studies have shown a higher prevalence of migraine in patients with SLE, although the exact relationship remains unclear. This study investigated the potential causal association between SLE and migraine using the powerful analytical tool of Mendelian randomization (MR).

METHODS

We performed two-sample MR analysis of publicly available summary statistic datasets using inverse variance-weighted (IVW), weighted median, and MR-Egger methods based on an SLE genome-wide association study (GWAS; 5201 cases; 9066 controls; the exposure frequency is 36.5%) as an exposure and migraine GWAS (15,905 cases; 264,662 controls) in individuals with European ancestry as outcomes, focusing on the two migraine subtypes MWA (6780 cases; 264,662 controls) and MWoA (5787 cases; 264,662 controls). Thepleiotropy and heterogeneity were performed.

RESULTS

We selected 42 single-nucleotide polymorphisms from SLE GWAS as instrumental variables (IVs) for SLE on migraine, and 41 SNP IVs for SLE on MWA or MWoA. The IVW (odds ratio [OR] = 1.01, 95% confidence interval [CI] = [0.99, 1.03], p = 0.271), weighted median (OR = 1.00, 95% CI = [0.97, 1.03], p = 0.914), and MR-Egger (OR = 1.04, 95% CI = [0.99, 1.09], p = 0.153) methods showed no causal effect of SLE on migraine. A causal effect of SLE was observed on MWA (IVW: OR = 1.05, 95% CI = [1.02, 1.08], p = 0.001; weighted median: OR = 1.05, 95% CI = [1.01, 1.10], p = 0.018; MR-Egger: OR = 1.07, 95% CI = [1.01, 1.14], p = 0.035 and pIVW < 0.017 [Bonferroni correction]) but not MWoA (IVW: OR = 0.99, 95% CI = [0.96, 1.02], p = 0.331; weighted median: OR = 0.98, 95% CI = [0.94, 1.03], p = 0.496; MR-Egger: OR = 1.02, 95% CI = [0.95, 1.09], p = 0.652). The results showed no significant pleiotropy or heterogeneity.

CONCLUSION

Our MR analysis demonstrated the complex relationship between SLE and migraine, suggesting a potential effect of SLE on the risk of MWA but not MWoA. These findings can aid in the development of improved subtype-specific management of migraine in patients with SLE.

Musculoskeletal symptoms in systemic lupus erythematosus patients and their impact on health-related quality of life

OBJECTIVES

To evaluate the musculoskeletal (MSK) symptoms experienced by SLE patients and determine how those symptoms relate to their health-related quality of life (HRQoL).

MATERIALS AND METHODS

This is a cross-sectional study that was carried out on 103 adult SLE patients. sociodemographic, clinical, and therapeutic data were recruited. They were asked to complete the following: Nordic Musculoskeletal, Short-Form McGill Pain, and Lupus QoL Questionnaires.

RESULTS

The mean age was 30.81 ± 9.44 years. There was a total of 86 females and 17 males (F: M:5:1). Almost all the patients reported MSK symptoms (96.1%). The maximum number of patients reported pain in the right and left wrist and hand (64.1%, 63.1%, respectively). One-fourth (25.2%) described at least five bodily sites of MSK symptoms, while 70.9% had more than five sites of MSK symptoms. Most of the patients described the pain as discomforting (40.8%). Patients with MSK symptoms scored significantly worse in all domains. In addition, the QoL scores of patients with more than 5 body sites of MSK symptoms were significantly lower than those of patients with fewer than 5 sites of MSK symptoms.

CONCLUSION

SLE patients have a high MSK burden, and MSK symptoms have a negative impact on HRQoL in these patients.

A Rare Case of Dual Metachronous Primary Malignancies, Chronic Myeloid Leukemia, and Tongue Carcinoma in a Patient With Long-Standing Systemic Lupus Erythematosus: A Case Report and Review of Literature

Patients with long-standing autoimmune diseases like systemic lupus erythematosus (SLE) are at a higher risk of developing hematological malignancies. However, chronic myeloid leukemia (CML) has rarely been reported in patients with SLE. Advancements in medical diagnostics and treatment have led to the life expectancy of SLE and CML patients moving closer to that of the general population, and it is not uncommon to encounter more than one malignancy in a cancer survivor. Although squamous cell carcinoma (SCC) of the skin has been reported in CML patients, mucosal SCC of the head and neck has rarely only been reported in CML survivors. The objective of this case report is to share our experience in treating a patient with dual metachronous primary malignancies, CML, and tongue carcinoma, along with long-standing SLE, managed by a multidisciplinary team.

Atherosclerosis Progression in the APPLE Trial Can Be Predicted in Young People With Juvenile-Onset Systemic Lupus Erythematosus Using a Novel Lipid Metabolomic Signature

OBJECTIVE

Patients with juvenile-onset systemic lupus erythematosus (JSLE) have increased atherosclerosis risk. This study investigated novel atherosclerosis progression biomarkers in the Atherosclerosis Prevention in Pediatric Lupus Erythematosus (APPLE) trial, the largest investigator-led randomized control trial of atorvastatin versus placebo for atherosclerosis progression in JSLE, using carotid intima-media thickness (CIMT) as the primary outcome.

METHODS

Unsupervised clustering of baseline CIMT and CIMT progression over 36 months was used to stratify patients with JSLE. Disease characteristics, cardiovascular risk scores, and baseline serum metabolome were investigated in CIMT-stratified patients. Machine learning techniques were used to identify and validate a serum metabolomic signature of CIMT progression.

RESULTS

Baseline CIMT stratified patients with JSLE (N = 151) into three groups with distinct high, intermediate, and low CIMT trajectories irrespective of treatment allocation, despite most patients having low cardiovascular disease risk based on recommended assessment criteria. In the placebo group (n = 60), patients with high versus low CIMT progression had higher total (P = 0.001) and low-density lipoprotein (LDL) (P = 0.002) cholesterol levels, although within the reference range. Furthermore, a robust baseline metabolomic signature predictive of high CIMT progression was identified in the placebo arm (area under the curve, 80.7%). Patients treated with atorvastatin (n = 61) had reduced LDL cholesterol levels after 36 months, as expected; however, despite this, 36% still had high atherosclerosis progression, which was not predicted by metabolomic biomarkers, suggesting nonlipid drivers of atherosclerosis in JSLE with management implications for this subset of patients.

CONCLUSION

Significant baseline heterogeneity and distinct subclinical atherosclerosis progression trajectories exist in JSLE. Metabolomic signatures can predict atherosclerosis progression in some patients with JSLE with relevance for clinical trial stratification.

A double-edged sword: interactions of CX3CL1/CX3CR1 and gut microbiota in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a systemic chronic disease initiated by an abnormal immune response to self and can affect multiple organs. SLE is characterized by the production of autoantibodies and the deposition of immune complexes. In regard to the clinical observations assessed by rheumatologists, several chemokines and cytokines also contribute to disease progression. One such chemokine and adhesion molecule is CX3CL1 (otherwise known as fractalkine). CX3CL1 is involved in cell trafficking and inflammation through recognition by its receptor, CX3CR1. The CX3CL1 protein consists of a chemokine domain and a mucin-like stalk that allows it to function both as a chemoattractant and as an adhesion molecule. In inflammation and specifically lupus, the literature displays contradictory evidence for the functions of CX3CL1/CX3CR1 interactions. In addition, the gut microbiota has been shown to play an important role in the pathogenesis of SLE. This review highlights current studies that illustrate the interactions of the gut microbiota and CX3CR1 in SLE.

Longitudinal follow-up of mixed connective tissue disease and overlapping autoimmune diseases of childhood onset in the Afro-descendant population of the French West Indies

INTRODUCTION

Overlap autoimmune syndromes (OAS) and mixed connective tissue disease (MCTD) are rare in children. We performed a retrospective, longitudinal and descriptive study of Afro-Caribbean patients from the French West Indies followed for MCTD and OAS to describe their characteristics and outcomes during childhood.

METHODS

Retrospective study from January 2000 to 2023. Listings of patients were obtained from multiple sources: computerized hospital archives and national hospital-based surveillance system, registry of pediatricians and adult specialists in internal medicine and the national registry for rare diseases. MCTD was defined according to Kasukawa's criteria. OAS was defined as overlapping features of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and dermatomyositis/autoimmune myositis (DM/AM).

RESULTS

Sixteen patients were included over a 23-year period (10 MCTD and 6 OAS). The incidence was 0.23 per 100,000 children-years. The mean age at diagnosis was 11.9 years old (2.4-17) with median follow up of 7.9 years (2.1-19.6). SLE phenotype was present in the highest, followed by SSc and DM/AM. Patients had an average of three flares during childhood (1-7). A quarter (25%) had symptomatic pulmonary arterial hypertension (PAH). Ninety-four percent received steroids during follow-up and 88% required a corticosteroid-sparing therapy. Three patients (19%) developed SLE after more than 10y of follow-up. There were no death and no chronic organ failure.

CONCLUSION

This is the largest pediatric cohort of MCTD and OAS in Afro-descendant patients treated in a country with a high standard of care. The clinical evolution did not differ between MCTD and OAS. The main complication was PAH, more frequent in our cohort.

Lupus Nephritis Biomarkers: A Critical Review

Lupus nephritis (LN), a major complication in individuals diagnosed with systemic lupus erythematosus, substantially increases morbidity and mortality. Despite marked improvements in the survival of patients with severe LN over the past 50 years, complete clinical remission after immunosuppressive therapy is achieved in only half of the patients. Therefore, timely detection of LN is vital for initiating prompt therapeutic interventions and improving patient outcomes. Biomarkers have emerged as valuable tools for LN detection and monitoring; however, the complex role of these biomarkers in LN pathogenesis remains unclear. Renal biopsy remains the gold standard for the identification of the histological phenotypes of LN and guides disease management. However, the molecular pathophysiology of specific renal lesions remains poorly understood. In this review, we provide a critical, up-to-date overview of the latest developments in the field of LN biomarkers.

Sociodemographic profiles and organ damage accural in the Black Women's Experience Living with Lupus study

OBJECTIVE

Black/African American women with systemic lupus erythematosus (SLE) experience greater organ damage and at younger ages than white women. The objective of this study was to advance research on SLE inequities by identifying sociodemographic risk profiles associated with organ damage accrual specifically among Black/African American women.

METHODS

Latent profile analysis was conducted among 438 Black/African American women with SLE living in Atlanta, GA and enrolled in the Black Women's Experiences Living with Lupus (BeWELL) Study (May 2015 to April 2017). Proportional hazard and Poisson regression models examined prospective associations between sociodemographic profiles and the timing and degree of organ damage accrual over 2 years.

RESULTS

Four profiles emerged: (1) "Younger/Lower SES with Uncontrolled SLE" (44.8%), (2) "Older/Lower SES with Uncontrolled SLE" (23.3%), (3) "Mid-SES with Controlled SLE" (19.6%), and (4) "Higher SES with Controlled SLE" (11.2%). Approximately 42% of participants experienced new organ damage during the follow-up period. Proportional hazard models indicated that "Older/Lower SES with Uncontrolled SLE" participants were at greatest risk of new organ damage (HR = 2.41; 95% CI = 1.39, 4.19), followed by "Younger/Lower SES with Uncontrolled SLE" participants (HR = 1.56; 95% CI = 0.92, 2.67), compared to those in the "Higher SES with Controlled SLE" profile. Poisson regression models revealed that these two groups also exhibited greater organ damage accrual (b = 0.98, SE = 0.24, 95% CI = 0.52, 1.44 and b = 0.72, SE = 0.23, 95% CI = 0.27, 1.17, respectively).

CONCLUSIONS

Black/African American women with fewer socioeconomic resources and uncontrolled SLE are at greatest risk for increasing disease severity over time. Social inequities likely contribute to racial inequities in SLE progression.

Exploring cardiovascular implications in systemic lupus erythematosus: A holistic analysis of complications, diagnostic criteria, and therapeutic modalities, encompassing pharmacological and adjuvant approaches

Systemic lupus erythematosus (SLE) poses a diagnostic challenge due to its heterogeneity. This study examines the cardiac complications of SLE comprehensively, covering pericarditis, myocarditis, pleural effusion, valvular disease, atherosclerosis, and cardiac arrhythmias. Nearly one-third of SLE-related deaths are attributed to cardiovascular diseases, necessitating a deeper understanding of cardiac pathophysiology. The impact of SLE on the cardiovascular system manifests in various ways, including recurrent and resistant pericarditis, severe myocarditis, and pleural effusion. Valvular diseases, atherosclerosis, and cardiac arrhythmias are prevalent, with immune complex deposition playing a role in atherosclerosis. Diagnostic criteria involve clinical features, laboratory findings, and autoantibodies, emphasizing the need for early diagnosis and a multidisciplinary diagnostic approach. The review explores pharmacological and non-pharmacological modalities for managing cardiac manifestations in SLE. Recommendations include NSAIDs, colchicine, and proton pump inhibitors for acute pericarditis, while selective immunosuppressive therapy is emerging for myocarditis. Valvular diseases require individualized treatment approaches, and careful corticosteroid management is crucial to avoid increased cardiovascular events. Anti-malarial therapy, particularly hydroxychloroquine, shows promise in mitigating cardiovascular risk factors. Non-pharmacological modifications, such as diet, exercise, and smoke cessation, significantly contribute to cardiovascular health in SLE patients. Adjuvant therapies involving glutathione and glutathione peroxidase focus on redox balance, offering potential interventions. This integrated approach combines diagnostic insights with diverse treatment modalities, providing a holistic strategy for managing cardiac complications in SLE. Ongoing research is essential to refine these strategies and optimize individualized treatment plans for improved patient outcomes.

Burden of systemic lupus erythematosus in clinical practice: baseline data from the SLE Prospective Observational Cohort Study (SPOCS) by interferon gene signature

OBJECTIVE

The longitudinal Systemic Lupus Erythematosus Prospective Observational Cohort Study (SPOCS) aims to assess SLE disease course overall and according to type I interferon 4 gene signature (IFNGS). Here, we describe SPOCS patient characteristics by IFNGS and baseline disease activity.

METHODS

SPOCS (NCT03189875) is an international study of patients with SLE according to Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) criteria. Enrolled patients from 135 centres in 8 countries were followed biannually for ≤3 years from June 2017 to November 2022. Baseline demographics, disease characteristics, organ system involvement/damage and flares were analysed descriptively according to SLE Disease Activity Index-2000 score (SLEDAI-2K <10/≥10) and IFNGS status (high/low).

RESULTS

The study population (n=823) was 93.2% female, with mean (SD) age 45.3 (13.9) years and 11.1 (9.2) years since diagnosis; 52.4% had baseline SLICC/ACR Damage Index score ≥1. Patients with SLEDAI-2K scores ≥10 (241 of 584, 41.3%) vs <10 were younger (mean 42.8 (13.7) vs 46.6 (14.2) years; nominal p=0.001), had shorter SLE duration (10.4 (8.6) vs 12.4 (9.6) years; nominal p=0.012) and more severe flares (12.9% vs 5.3%; nominal p=0.001). IFNGS-high patients (522 of 739, 70.6%) were younger than IFNGS-low patients at first SLE manifestation (30.0 (12.7) vs 36.8 (14.6) years; nominal p<0.001). Proportions of IFNGS-high patients differed according to race (nominal p<0.001), with higher proportions among Asian (83.3%) and black (86.5%) versus white patients (63.5%). Greater proportions of IFNGS-high versus IFNGS-low patients had haematological (12.6% vs 4.1%), immunological (74.4% vs 45.6%) or dermal (69.7% vs 62.2%) involvement.

CONCLUSIONS

We identified key characteristics of patients with high disease activity and/or elevated type I IFN signalling, populations with SLE with high unmet needs. Baseline SLEDAI-2K ≥10 was associated with shorter disease duration and more severe flares. IFNGS-high patients were younger at diagnosis and had distinct patterns of organ involvement, compared with IFNGS-low patients.

Altered expression of miR-125a and dysregulated cytokines in systemic lupus erythematosus: Unveiling diagnostic and prognostic markers

BACKGROUND

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder impacting multiple organs, influenced by genetic factors, especially those related to the immune system. However, there is a need for new biomarkers in SLE. MicroRNA-125a (miR-125a) levels are decreased in T cells, B cells, and dendritic cells of SLE patients. MiR-125a plays a regulatory role in controlling the levels of tumor necrosis factor-alpha (TNF-α) and interleukin 12 (IL-12), which are crucial pro-inflammatory cytokines in SLE pathogenesis.

AIM

To assess the levels of miR-125a, IL-12, and TNF-α in SLE patients' plasma, evaluating their diagnostic and prognostic value.

METHODS

The study included 100 healthy individuals, 50 newly diagnosed (ND), and 50 SLE patients undergoing treatment. The patients were monitored for a duration of 24 wk to observe and record instances of relapses. MiR-125a expression was measured using real-time reverse transcription polymerase chain reaction, while ELISA kits were used to assess IL-12 and TNF-α production.

RESULTS

The results showed significantly reduced miR-125a expression in SLE patients compared to healthy individuals, with the lowest levels in ND patients. TNF-α and IL-12 expression levels were significantly elevated in SLE patients, especially in the early stages of the disease. Receiver operating characteristic curve analyses, and Cox-Mantel Log-rank tests indicated miR-125a, TNF-α, and IL-12 as proper diagnostic biomarkers for SLE. A negative correlation was found between plasma miR-125a expression and IL-12/TNF-α levels in SLE patients.

CONCLUSION

Decreased miR-125a levels may be involved in the development of SLE, while elevated levels of IL-12 and TNF-α contribute to immune dysregulation. These findings offer new diagnostic and prognostic markers for SLE. Moreover, the negative correlation observed suggests an interaction between miR-125a, TNF-α, and IL-12. Further research is necessary to uncover the underlying mechanisms that govern these relationships.

Circulating lymphocyte subpopulations in patients with systemic lupus erythematosus and their correlation with disease activity

The aim of the present study was to evaluate the overall alterations of peripheral blood lymphocyte subsets in patients with systemic lupus erythematosus (SLE). A total of 120 patients diagnosed with SLE and 64 health donors were enrolled. The lymphocyte subsets were detected using flow cytometry. Then the changes of lymphocyte subsets in patients and their correlation with disease activity were investigated. Compared with healthy controls, the counts of lymphocytes, T cells, B cells and NK cells in SLE patients were significantly decreased. Further analysis of T cells subpopulations revealed that the decrease in T cells counts in SLE patients was mainly attributed to a sharp decrease in CD4 + T cells counts. Meanwhile, there was a positive correlation between CD4 + T cells counts and serum complement 3 levels, and patients with lower CD4 + T cells counts had higher SLEDAI score. The counts of CD8 + T cells were comparable between SLE patients and controls, while the proportion of CD8 + T cells and cytotoxic T cells (CD8 + CD28 +) was prominently higher in SLE patients. Besides, the expression of HLA-DR on the surface of T and NK cells was significantly upregulated in SLE patients. Circulating lymphocyte subsets of SLE patients were seriously dysregulated, characterized by a decrease in CD4 + T cells and NK cells, as well as an increase in the proportion of activated T and NK cells. Reduction in CD4 + T cells in SLE patients was highly consistent with disease activity, indicating the crucial role of CD4 + T cells in the onset and progression of SLE.

Systemic lupus erythematosus in American Indian/Alaska natives: Incorporating our new understanding of the biology of trauma

OBJECTIVE

To review the literature regarding systemic lupus erythematosus (SLE) in American Indian/Alaska Native (AI/AN) people and relate prevalence and/or disease severity to our emerging understanding of the biology of trauma and toxic stress.

METHODS

We conducted a search and review of the literature using search terms "lupus and American Indians" "ACEs and disease outcome" "Biology of Adversity" "lupus and ACE scores," " lupus and childhood abuse." These search criteria were entered into Google Scholar and articles retrieved from PubMed, NBCI. This approach yielded a small numbers of papers used throughout this review. We excluded articles that were not published in a peer reviewed journals, as well as editorial commentaries.

RESULTS

In the AI/AN population, SLE shows high prevalence rates and severe disease manifestations, comparable to the African American population. AI/AN populations also have high rates of childhood trauma. Toxic stress and trauma such as those catalogued in the Adverse Childhood Experiences (ACE) study have broad-reaching immunologic and epigenetic effects that are likely to be relevant to our understanding of SLE in AI/AN people.

CONCLUSIONS

AI/AN people have high rates of SLE. These high rates are likely to be driven by many complex factors, not all of which are genetic. Future research is needed to establish (or refute) a causal connection between the biology of adversity and SLE in socially marginalized and historically traumatized populations.

[What is proven in the treatment of systemic lupus erythematosus?]

Systemic lupus erythematosus (SLE) is an autoimmune disease with variable clinical presentation and organ involvement. Early diagnosis and rapid achievement of low disease activity or remission reduces organ damage and improves prognosis. Therapeutic principles can be divided into so-called basic measures and immunosuppressive treatment. Novel drugs have been developed in recent years, with new classes of agents being added for the treatment of SLE. These include biologic therapies and approved therapeutic options for the treatment of lupus nephritis. In light of improved treatment options, good disease control can now frequently be achieved; with savings on glucocorticoids, combination therapies are increasingly being used. Of great importance is the consistent use of basic measures, which include the use of hydroxychloroquine, optimization of cardiovascular risk factors, UV protection, bone-protective measures, and the implementation of vaccinations. In the treatment of lupus nephritis, conservative therapeutic measures for nephroprotection play a crucial role in renal prognosis. Finally, non-pharmacological therapy options such as exercise therapy are of great importance for improving quality of life.

Scleral changes in systemic lupus erythematosus patients using swept source optical coherence tomography

Purpose

This study aims to examine scleral thickness in patients with systemic lupus erythematosus (SLE) without clinically evident scleritis and episcleritis, utilizing swept-source optical coherence tomography (SS-OCT).

Methods

This cross-sectional single center study compared scleral thickness (Nasal scleral thickness 1mm, 2mm, 3mm, 6mm from scleral spur; Temporal scleral thickness 1mm, 2mm, 3mm, 6mm from scleral spur) in 73 SLE patients without clinically evident scleritis and episcleritis and 48 healthy volunteers with SS-OCT. Further, we investigated the correlation between scleral thickness in SLE patients and various parameters including laboratory markers, disease duration, disease activity, and organ involvement.

Results

Across all measured sites (nasal scleral thickness at distances of 1mm, 2mm, 3mm, and 6mm from the scleral spur, and temporal scleral thickness at the same distances), the scleral thickness in the SLE group was significantly greater than that in the control group (all p-values <0.001). SLE patients with a disease duration of 5 years or less exhibited a higher scleral thickness compared to those with a more prolonged disease duration. Patients with a higher erythrocyte sedimentation rate (ESR) had a thinner temporal scleral thickness. However, no significant associations were identified between scleral thickness and disease activity, organ involvement, or other laboratory markers.

Conclusion

Scleral thickness measured by SS-OCT was higher in SLE patients than healthy controls. Changes in scleral thickness in SLE patients are related to disease duration and ESR. SS-OCT can detect asymptomatic structural changes in SLE patients and may be a useful tool in the evaluation of early scleral abnormality.

Clinicopathological prognostic characteristics and long‑term outcomes of patients with breast cancer and collagen disorder in comparison to those without collagen disorder

Collagen disorders are chronic autoimmune diseases with a complex clinical course; however, the risk of breast cancer in patients with collagen disorders remains unclear. The present study aimed to investigate long-term outcomes in women with breast cancer and collagen disorders. A total of 25 patients with breast cancer and collagen disorders who were treated between January 2004 and December 2011 were included. The clinicopathological factors, treatment, recurrence-free survival (RFS) and overall survival (OS) were reviewed. The mean age was 56.4±12.6 years, and 14, eight and three patients had cancer of clinical stages I, II and III, respectively. Regarding comorbid collagen disorders, 11 patients had rheumatoid arthritis, four had systemic lupus erythematosus, four had polymyositis/dermatomyositis, two had mixed connective tissue disease, two had Sjogren's syndrome, one had scleroderma and one had adult-onset Still's disease. The expression statuses of hormone receptors (HR) and human epidermal growth factor receptor 2 (HER2) were HR(+), HER2(+) and HR(-)HER2(-) in 20 (80.0%), four (16.0%) and four (16.0%) patients, respectively. A total of 22 (84.0%) patients received steroids or immunosuppressive drugs for collagen disorders. The collagen disorder group had a higher mean Ki-67 labeling index than the control group (41.1 vs. 20.8%; P=0.007). After median observation periods of 103 and 114 months, the RFS and OS rates were lower in the collagen group than in the control group (64.5 and 80.7% vs. 85.3 and 94.3%, respectively; P<0.01). Patients with breast cancer and collagen disorders had relatively high Ki-67 expression, and relatively low RFS and OS rates. Thorough follow-up is necessary for patients with breast cancer who also have collagen disorders and high Ki-67 values.
