Abstract
LncRNAs play an important role in autoimmune diseases. The purpose of this study was to explore the role of lncRNA SNHG1 in systemic lupus erythematosus (SLE), and laid a theoretical foundation for the study of SLE. The basic clinical information of all subjects was first collected for statistical analysis, and SNHG1 expression in the serum of all subjects was detected by RT-qPCR. The value of SNHG1 in the diagnosis of SLE was assessed by ROC. The correlation between SNHG1 and each blood sample index was analyzed by Pearson correlation analysis. The role of SNHG1 in primary peripheral blood mononuclear cells (PBMCs) apoptosis was explored. SNHG1 expression is relatively upregulated in patients with SLE compared to healthy people. SNHG1 expression was positively correlated with SLEDAI score, IgG, CRP, and ESR, and negatively correlated with C3 and C4. ROC indicated that SNHG1 has the potential to assist in the diagnosis of SLE. PBMCs apoptosis in SLE was higher than that in control group, the knockdown and overexpression of SNHG1 could correspondingly inhibit and promote PBMCs apoptosis. SNHG1 has the potential to be a diagnosis marker for SLE and may be involved in regulating PBMCs apoptosis.

Wang S, Ning W, Tang H, Mu C, Huang X. Efficacy and safety study of targeted small-molecule drugs in the treatment of systemic lupus erythematosus. Arthritis Res Ther 2024; 26:98. [PMID: 38730460 PMCID: PMC11083747 DOI: 10.1186/s13075-024-03331-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 04/25/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Targeted small-molecule drugs in the treatment of systemic lupus erythematosus (SLE) have attracted increasing attention from clinical investigators. However, there is still a lack of evidence on the difference in the efficacy and safety of different targeted small-molecule drugs. Therefore, this study was conducted to assess the efficacy and safety of different targeted small-molecule drugs for SLE. METHODS Randomized controlled trials (RCTs) on targeted small-molecule drugs in the treatment of SLE in PubMed, Web of Science, Embase, and Cochrane Library were systematically searched as of April 25, 2023. Risk of bias assessment was performed for included studies using the Cochrane's tool for evaluating the risk of bias. The primary outcome indicators were SRI-4 response, BICLA response, and adverse reaction. Because different doses and courses of treatment were used in the included studies, Bayesian network meta-regression was used to investigate the effect of different doses and courses of treatment on efficacy and safety. RESULTS A total of 13 studies were included, involving 3,622 patients and 9 targeted small-molecule drugs. The results of network meta-analysis showed that, in terms of improving SRI-4, Deucravacitinib was significantly superior to that of Baricitinib (RR = 1.32, 95% CI (1.04, 1.68), P < 0.05). Deucravacitinib significantly outperformed the placebo in improving BICLA response (RR = 1.55, 95% CI (1.20, 2.02), P < 0.05). In terms of adverse reactions, targeted small-molecule drugs did not significantly increase the risk of adverse events as compared to placebo (P > 0.05). CONCLUSION Based on the evidence obtained in this study, the differences in the efficacy of targeted small-molecule drugs were statistically significant as compared to placebo, but the difference in the safety was not statistically significant. The dose and the course of treatment had little impact on the effect of targeted small-molecule drugs. Deucravacitinib could significantly improve BICLA response and SRI-4 response without significantly increasing the risk of AEs. Therefore, Deucravacitinib is very likely to be the best intervention measure. Due to the small number of included studies, more high-quality clinical evidence is needed to further verify the efficacy and safety of targeted small-molecule drugs for SLE.

[PMID: 38079010 DOI: 10.1007/s10067-023-06833-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 10/20/2023] [Accepted: 11/24/2023] [Indexed: 02/20/2024]
Abstract
Biologic agents are increasingly being used to treat adult patients with systemic lupus erythematosus (SLE). However, the available data on biologic agents' use in childhood-onset SLE (cSLE) remains limited. To collate available evidence related to the efficacy and safety of using biologic agents in cSLE. The study followed the PRISMA checklist for reporting the data and conducted a thorough search using PubMed, Cochrane Library, and Scopus from January 2005 to August 2023. Only articles meeting specific criteria were included, focusing on cSLE, the use of biologic agents, and having outcome measures at six- and 12-month follow-ups for safety and efficacy. Case reports were excluded, and four independent reviewers screened the articles for accuracy, with a fifth reviewer resolving any discrepancies that arose to achieve a consensus. The final selection included 18 studies with a total of 593 patients treated with biologic agents for severe and/ or refractory cSLE. The most common indication for using biologic agents was lupus nephritis. Rituximab was used in 12 studies, while belimumab was used in six studies. The studies evaluated the efficacy of biologic agents based on SLE disease activity scores, laboratory parameter improvements, and reduced corticosteroid dosage. Positive outcomes were reported, with improvements in renal, hematologic, and immunologic parameters along with mild adverse effects, mostly related to mild infections and infusion reactions. Belimumab and rituximab have shown promise as potential treatments for severe and refractory cSLE cases, leading to decreased disease activity and complete or partial remission in many patients with an acceptable safety profile. However, further research is needed to better understand their benefits and potential risks in these patients. Key Points • This review emphasizes the lack of sufficient randomized controlled trials exploring the use of biologics in childhood systemic lupus erythematosus (cSLE). • Treatment plans for cSLE are being derived from those used for adult systemic lupus erythematosus. • According to current evidence, belimumab and rituximab can be potential treatment options for refractory and severe cases of cSLE. • Additional studies are required to reach more definitive conclusions.

Abstract
Lupus nephritis (LN) represents one of the most severe complications of systemic lupus erythematosus, leading to end-stage kidney disease in worst cases. Current first-line therapies for LN, including mycophenolate mofetil (MMF) and azathioprine (AZA), fail to induce long-term remission in 60-70% of the patients, evidencing the urgent need to delve into the molecular knowledge-gap behind the non-response to these therapies. A longitudinal cohort of treated LN patients including clinical, cellular and transcriptomic data, was analyzed. Gene-expression signatures behind non-response to different drugs were revealed by differential expression analysis. Drug-specific non-response mechanisms and cell proportion differences were identified. Blood cell subsets mediating non-response were described using single-cell RNASeq data. We show that AZA and MMF non-response implicates different cells and regulatory functions. Mechanistic models were used to suggest add-on therapies to improve their current performance. Our results provide new insights into the molecular mechanisms associated with treatment failures in LN.

Abstract
Glomerulonephritis (GN) is the most common cause of end-stage renal failure worldwide; in most cases, it cannot be cured and can only delay the progression of the disease. At present, the main treatment methods include symptomatic therapy, immunosuppressive therapy, and renal replacement therapy. However, effective treatment of GN is hindered by issues such as steroid resistance, serious side effects, low bioavailability, and lack of precise targeting. With the widespread application of nanoparticles in medical treatment, novel methods have emerged for the treatment of kidney diseases. Targeted transportation of drugs, nucleic acids, and other substances to kidney tissues and even kidney cells through nanodrug delivery systems can reduce the systemic effects and adverse reactions of drugs and improve treatment effectiveness. The high specificity of nanoparticles enables them to bind to ion channels and block or enhance channel gating, thus improving inflammation. This review briefly introduces the characteristics of GN, describes the treatment status of GN, systematically summarizes the research achievements of nanoparticles in the treatment of primary GN, diabetic nephropathy and lupus nephritis, analyzes recent therapeutic developments, and outlines promising research directions, such as gas signaling molecule nanodrug delivery systems and ultrasmall nanoparticles. The current application of nanoparticles in GN is summarized to provide a reference for better treatment of GN in the future.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is an autoimmune disorder characterized by abnormal autoantibody production, inflammation, and organ damage. Most SLE treatment strategies aim to induce remission or reduce disease activity while avoiding flares. Baricitinib has been used effectively to manage various inflammatory diseases, and some randomized controlled trials (RCT) have shown that it is beneficial in treating SLE. The current study aims to assess the efficacy of baricitinib in treating SLE patients. MATERIALS AND METHODS Various databases such as PubMed, Scopus, and Science Direct were searched to obtain eligible studies for the present meta-analysis. Data such as baseline characteristics of patients, doses of the baricitinib, follow-up duration, and treatment outcome in the form of SLE responder index-4 (SRI-4) and lupus low disease activity state (LLDAS) were extracted. Combined odds ratio, 95% confidence interval, and probability values were calculated to study the efficacy of baricitinib in treating SLE patients. A p-value less than .05 was taken as significant. Comprehensive meta-analysis v3 was used for all analyses. RESULTS Three articles were found eligible for the present meta-analysis comprising 614 patients with placebo, 614 SLE patients receiving 4 mg, and 621 patients with 2 mg of baricitinib. Meta-analysis revealed a beneficial effect of 4 mg baricitinib in SLE patients compared to placebo, as measured by an increase in the SRI-4 (p = .006, OR = 1.370) and LLDAS (p = .083, OR = 1.252) rates. In contrast to the placebo group, however, patients receiving 2 mg of baricitinib exhibited no significant improvement. The trial sequential analysis revealed the need for additional RCTs to determine the role of baricitinib in treating SLE patients. CONCLUSION In treating SLE patients, administrating a higher dose of baricitinib (4 mg) may be effective. However, additional RCTs in different populations with larger sample sizes are required to validate our findings.

Abstract
INTRODUCTION Cutaneous lupus erythematosus (CLE) is an autoimmune disease that is clinically heterogenous and may occur with or without the presence of systemic lupus erythematosus (SLE). While existing on a spectrum, CLE and SLE present differences in their underlying pathogenesis and therapeutic responses. No new therapies have been approved in recent decades by the U.S. Food and Drug Administration for CLE, although frequently refractory to conventional therapies. There is an unmet need to develop effective drugs for CLE as it significantly impacts patients' quality of life and may leave irreversible disfiguring damage. AREAS COVERED This review provides an update on the latest phase 2 and 3 clinical trials performed in CLE or SLE using skin-specific outcome measures. Emergent therapies are presented alongside their mechanism of action as recent translational studies have permitted identification of critical targets among immune cells and/or pathways involved in CLE. EXPERT OPINION While the recent literature has few trials for CLE, drugs targeting type I interferon, its downstream signaling and plasmacytoid dendritic cells have shown promising results. Further research is required to develop long-awaited effective therapies, and this review highlights the importance of implementing trials dedicated to CLE to fill the current gap in CLE therapeutics.

Recommendations for the use of anti-dsDNA autoantibodies in the diagnosis and follow-up of systemic lupus erythematosus - A proposal from an expert panel. Autoimmun Rev 2023; 22:103479. [PMID: 37967782 DOI: 10.1016/j.autrev.2023.103479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 11/10/2023] [Indexed: 11/17/2023]
Abstract
Anti-dsDNA autoantibodies are listed as one of the classification criteria for systemic lupus erythematosus (SLE) and are relatively effective indicators for monitoring disease activity and treatment response. Therefore, clinicians rely on them to diagnose and adjust medication and treatment strategies for SLE patients. However, the use of anti-dsDNA antibodies is not free from controversy. Part of this controversy stems from the fact that anti-dsDNA antibodies are found in several disorders, besides SLE. In addition to this, anti-dsDNA antibodies are a heterogeneous group of antibodies, and their determination still lacks proper standardization. Moreover, anti-dsDNA testing specificity and diagnostic performance change depending on the population under study. These and other issues result in inconsistency and encumber the clinical use of anti-dsDNA antibodies. A panel of medical laboratory and clinical experts on SLE discussed such issues based on their clinical experience in a first meeting, establishing a series of recommendations. The proceedings of this first meeting, plus an exhaustive review of the literature, were used to compose a paper draft. The panel subsequently discussed and refined this draft in a second meeting, the result of which is this paper. This document is relevant to clinical laboratories as it guides to improving diagnosis and monitoring of SLE. Simultaneously, it will help laboratories compile more informative reports, not limited to a mere number. It is also relevant to clinical doctors who wish to better understand laboratory methods so that they can do a more efficient, better-aimed laboratory test ordering.

Abstract
MSK is the most common and impactful symptom of lupus at a population level. It has a variety of different presentations, but joint swelling is often not present despite imaging-proven synovitis. Imaging with US and MRI has been shown to improve detection of inflammation and identify treatment-responsive patients. In contrast, the SLEDAI shows poor sensitivity, specificity, and responsiveness. While BILAG and SLE-DAS are superior, they are still less accurate than imaging. These issues may explain why the evidence for conventional and biologic therapies for MSK lupus is complex. In clinical practice, physicians must take care not to underestimate MSK inflammation and consider using imaging. Future research should investigate new therapeutic targets specifically for synovitis and more sensitive outcome measures and trials to evaluate them.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. It affects multiple organ systems and is associated with significant morbidity and mortality. The treatment for SLE primarily aims at controlling and remitting the disease. Baricitinib is a kinase inhibitor that selectively inhibits JAK1 and JAK2 enzymes. Recently this drug is being investigated as a potential therapeutic option for SLE. OBJECTIVE To analyze the efficacy of baricitinib in treating SLE. METHODS Search of databases identified relevant studies that reported the efficacy of baricitinib. Data of patient characteristics, intervention details, and outcomes was extracted. The data from the studies were pooled using a random-effects model. The odds ratio with their respective 95 % confidence intervals (CI) were calculated to analyze the results. A p value of <0.05 was considered statistically significant. RESULTS 3 RCTs were included in the analysis. 1849 patients were extracted from the included studies, most of the participants were females with a mean age of 43 years. The studies showed a significant effect of Baricitinib 4 mg in achieving SRI-4 [OR = 1.42 (95 % CI: 1.01, 2.00); p = 0.04]. There was no significant association of Baricitinib 2 mg in achieving SRI-4. Both dosages of the drug did not have any significant association in achieving LLDAS as compared to placebo. Serious adverse side effects were significantly associated with Bar 4 mg as compared to Bar 2 mg. CONCLUSION Our meta-analysis suggests that baricitinib might be a potential treatment option for SLE. Further large-scale clinical trials are needed to confirm our findings. Potential side effects should also be considered while the administration of this drug.

Abstract
INTRODUCTION The utilisation of telemedicine has been rapidly growing among patients with rheumatic diseases, especially following the corona virus disease 2019 pandemic. Ease and convenience appear to dominate the reasons for this growth. However, the effects of this approach in patients with systemic lupus erythematosus (SLE) are yet to be revealed. In this study, we examined the effect of telemedicine on disease activity assessment and damage scores in patients with SLE. METHODS This case-crossover study was nested within a national prospective cohort of patients with SLE in Saudi Arabia. Patients with SLE were included if they fulfilled the Systemic Lupus International Collaborating Clinics classification criteria between March 2020 and March 2021 and were assessed at three time points with 3 months between assessments, according to the standardised protocol of this cohort. Telemedicine was conducted for the first evaluation, while in-person assessments were used at the second and third visits. The primary outcome was the difference in the SLE disease activity index 2000 (SLEDAI-2K) score. The primary analysis was conducted using the repeated measure model and adjusted for potential confounders, including demographics, medications, and changes in steroid doses. Several sensitivity analyses were conducted to mitigate selection and time-varying confounders. RESULTS A total of 92 participants were included in this study. Most patients were females (88%), with a mean (±standard deviation [SD]) age of 36 (±13) years. The mean (±SD) disease activity scores at baseline were as follows: SLEDAI-2K, 5 (±5); SLE responder index, 3.8 (±3.5); Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index, 1 (±1). The mean difference in SLEDAI-2K score was -1.641 (95% confidence interval -2.773 to -0.510, p = 0.005*) between telemedicine and follow-up visits. The results were consistent in all sensitivity analyses. CONCLUSION We found that telemedicine assessment was associated with a much higher disease activity score than subsequent assessments, which may suggest an overestimation of disease activity and later assessment accuracy. Cautious adoption has been suggested for SLE patients with active disease.

Efficacy and safety of Janus kinase inhibitors in systemic and cutaneous lupus erythematosus: A systematic review and meta-analysis. Autoimmun Rev 2023; 22:103440. [PMID: 37678618 DOI: 10.1016/j.autrev.2023.103440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 09/03/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Janus kinase (JAK) inhibitors have been proven to be effective and safe in various autoimmune diseases. However, there is still a lack of comprehensive evidence regarding their efficacy and safety in systemic and cutaneous lupus erythematosus. METHODS We searched for systemic and cutaneous lupus erythematosus patients who were treated with JAK inhibitors in PubMed, Embase, Web of Science, and the Cochrane Library until February 28, 2023. The quality of clinical trials was assessed using the Cochrane risk-of-bias tool. Meta-analysis was conducted when at least three studies had comparable measures of outcome. If meta-analysis was not feasible, a descriptive review was carried out. RESULTS We included 30 studies, consisting of 10 randomized controlled trials and 20 case series or reports, with a total of 2,460 patients. JAK inhibitors were found to be more effective than placebo in systemic lupus erythematosus (SLE) based on the percentage of achieving SLE Responder Index (SRI)-4 response (RR = 1.18; 95% CI 1.07 to 1.31; p = 0.001), British Isles Lupus Assessment Group -based Composite Lupus Assessment (BICLA) response (RR = 1.16; 95% CI 1.02 to 1.31; p = 0.02), Lupus Low Disease Activity State (LLDAS) (RR = 1.28; 95% CI 1.07 to 1.54; p = 0.008), and Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2 K) remission of arthritis or rash (RR = 1.09; 95% CI 1.00 to 1.18; p = 0.04), particularly in treating musculoskeletal and mucocutaneous involvement. However, the effect of JAK inhibitors on cutaneous lupus erythematosus was uncertain. JAK inhibitors and placebo had a similar incidence of adverse events (RR = 1.01; 95% CI 0.97 to 1.04; p = 0.65). CONCLUSION JAK inhibitors could be a potential treatment option for systemic and cutaneous lupus erythematosus, particularly in treating cutaneous and musculoskeletal lesions of SLE. JAK inhibitors had a safe profile.

Efficacy and safety of telitacicept in patients with systemic lupus erythematosus: a multicentre, retrospective, real-world study. Lupus Sci Med 2023; 10:e001074. [PMID: 38007228 PMCID: PMC10679987 DOI: 10.1136/lupus-2023-001074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Accepted: 11/06/2023] [Indexed: 11/27/2023]
Abstract
OBJECTIVE To examine the efficacy and safety of telitacicept in the treatment of patients with SLE in everyday clinical practice. METHODS Seventy-two patients with active SLE who received telitacicept for more than 24 weeks at multiple centres in China between 2019 and 2022 were retrospectively identified. Twenty-one of these patients received 52 continuous weeks of treatment with telitacicept. Treatment outcomes were analysed separately according to whether patients had renal or haematological abnormalities. Trajectory analysis was performed to identify patients with a limited response. Factors contributing to a limited response were explored by multivariable logistic regression analysis. RESULTS After treatment with telitacicept for 4, 12, 24 and 52 weeks, 22.22%, 54.17%, 72.22% and 80.95% of patients, respectively, achieved an SLE Responder Index 4; 8.33%, 26.39%, 34.72% and 47.62% achieved a Lupus Low Disease Activity State; and 0%, 4.17%, 8.33% and 23.81% achieved remission. Significant decreases in serum IgA, IgG and IgM levels were observed at 4 weeks and showed a downward trend at 12, 24 and 52 weeks. The median 24-hour urinary protein declined from 1323.5 mg to 224.0 mg in patients with lupus nephritis after treatment with telitacicept for 52 weeks. Furthermore, a large proportion of patients (10 of 13) with haematological abnormalities recovered after 52 weeks of treatment with telitacicept. No severe adverse events were reported during the observation period. Age appeared to have a negative impact on treatment efficacy. CONCLUSIONS Telitacicept demonstrated favourable efficacy and safety in patients with active SLE and improved the renal and haematological manifestations of the disease.

Abstract
OBJECTIVE SLE is a common multisystem autoimmune disease with chronic inflammation. Many efficacy evaluation indicators of randomised clinical trials (RCTs) for SLE have been proposed but the comparability remains unknown. We aim to explore the preference and comparability of indicators reporting response rate and provide basis for primary outcome selection when evaluating the efficacy of SLE pharmaceutical treatment. METHODS We systematically searched three databases and three registries to identify pharmacological intervention-controlled SLE RCTs. Relative discriminations between indicators were assessed by the Bayesian hierarchical linear mixed model. RESULTS 33 RCTs met our inclusion criteria and we compared eight of the most commonly used indicators reporting response rate. SLE Disease Activity Index 4 (SLEDAI-4) and SLE Responder Index 4 were considered the best recommended indicators reporting response rate to discriminate the pharmacological efficacy. Indicator preference was altered by disease severity, classification of drugs and outcome of trials, but SLEDAI-4 had robust efficacy in discriminating ability for most interventions. Of note, BILAG Index-based Combined Lupus Assessment showed efficacy in trials covering all-severity patients, as well as non-biologics RCTs. The British Isles Lupus Assessment Group response and Physician's Global Assessment response were more cautious in evaluating disease changes. Serious adverse event was often applied to evaluate the safety and tolerability of treatments rather than efficacy. CONCLUSIONS The impressionable efficacy discrimination ability of indicators highlights the importance of flexibility and comprehensiveness when choosing primary outcome(s). As for trials that are only evaluated by SLEDAI-4, attention should be paid to outcome interpretation to avoid the exaggeration of treatment efficacy. Further subgroup analyses are limited by the number of included RCTs. PROSPERO REGISTRATION NUMBER CRD42022334517.

Abstract
Systemic autoimmune diseases are characterized by increased production of type I interferon (IFN-1) and upregulation of IFN-1-inducible genes, suggesting an important role of the IFN-1 pathway in their pathogenesis. Recent studies have demonstrated increased IFN-1 expression in both primary and secondary antiphospholipid syndrome (APS), along with increased toll-like receptor type 9 activity and plasmacytoid dendritic cell function. The increasing knowledge of the association between IFN-1 and APS pathology may provide a rationale for conducting clinical trials to assess the efficacy of IFN-1-targeting drugs in reducing APS-related complications. In this narrative review, we summarize the current knowledge on the role of IFN-1 in APS pathogenesis, explore its clinical implications, and examine the existing evidence regarding therapeutic options that have been investigated to date.

Abstract
Background: Tripterygium glycosides have been used to treat systemic lupus erythematosus (SLE) for a long time, showing the effects of immune regulation. We aimed to evaluate the benefits and risks of Tripterygium Glycosides Tablets (TGT) for patients with SLE. Methods: We searched electronic databases and clinical trial registries for relevant randomized controlled trials (RCTs). We identified eligible RCTs and assessed risk of bias. We conducted a meta-analysis to estimate the pooled effects. The Trial Sequential Analysis (TSA) 0.9.5.10 software was used to verify the reliability of the results. Results: Eight RCTs encompassing 538 patients with SLE were included. TGT combined with conventional treatments (CTs) was superior to CTs alone in reducing lupus activity (MD = -1.66, 95% CI = -2.07 to -1.26, p < 0.00001, low-certainty evidence) and improving overall response rate (ORR) (RR = 1.21, 95% CI = 1.11 to 1.32, p < 0.0001, moderate-certainty evidence). The robustness of the results was confirmed by TSA. Regarding safety, there was no statistical difference in the overall incidence of adverse reactions between the two groups. Conclusion: In patients with SLE, TGT might safely reduce disease activity. However, further high-quality studies are needed to firmly establish the clinical efficacy of TGT.

Abstract
Lupus nephritis (LN) is a frequent and serious complication of systemic lupus erythematosus (SLE), impairing patients' quality of life and significantly increasing mortality. Despite optimizing the use of conventional immunosuppressants and other biological drugs, its management remains unsatisfactory. This is mainly due to the heterogeneity of SLE, but also to insufficiently effective treatment regimens and clinical trial limitations (strict criteria, low number of patients included, and side effects). Most clinical trials of new biological therapies have failed to meet their primary endpoints in both general SLE and LN, with only two biological drugs (belimumab and anifrolumab) being approved by the Food and Drug Administration (FDA) for the treatment of SLE. Recently, several Phase II randomized controlled trials have evaluated the efficacy and safety of new biologics in LN, and some of them have demonstrated an improvement in clinical and laboratory measures. Multi-target therapies are also being successfully developed and encourage a belief that there will be an improvement in LN outcomes.

Abstract
SLE is a complex autoimmune disease with considerable unmet need. Numerous clinical trials designed to investigate novel therapies are actively enrolling patients straining limited resources and creating inefficiencies that increase enrolment challenges. This has motivated investigators developing novel drugs and treatment strategies to consider innovative trial designs that aim to improve the efficiency of generating evidence; these strategies propose conducting fewer trials, involving smaller numbers of patients, while maintaining scientific rigour in safety and efficacy data collection and analysis. In this review we present the design of two innovative phase IIb studies investigating efavaleukin alfa and rozibafusp alfa for the treatment of SLE which use an adaptive study design. This design was selected as a case study, investigating efavaleukin alfa, in the Food and Drug Administration's Complex Innovative Trial Design Pilot Program. The adaptive design approach includes prospectively planned modifications at predefined interim timepoints. Interim assessments of futility allow for a trial to end early when the investigational therapy is unlikely to provide meaningful treatment benefits to patients, which can release eligible patients to participate in other-potentially more promising-trials, or seek alternative treatments. Response-adaptive randomisation allows randomisation ratios to change based on accumulating data, in favour of the more efficacious dose arm(s), while the study is ongoing. Throughout the trial the placebo arm allocation ratio is maintained constant. These design elements can improve the statistical power in the estimation of treatment effect and increase the amount of safety and efficacy data collected for the optimal dose(s). Furthermore, these trials can provide the required evidence to potentially serve as one of two confirmatory trials needed for regulatory approval. This can reduce the need for multiple phase III trials, the total patient requirements, person-exposure risk, and ultimately the time and cost of investigational drug development programmes.

Abstract
Systemic lupus erythematosus (SLE) is a genetically predisposed, female-predominant disease, characterized by multiple organ damage, that in its most severe forms can be life-threatening. The pathogenesis of SLE is complex and involves cells of both innate and adaptive immunity. The distinguishing feature of SLE is the production of autoantibodies, with the formation of immune complexes that precipitate at the vascular level, causing organ damage. Although progress in understanding the pathogenesis of SLE has been slower than in other rheumatic diseases, new knowledge has recently led to the development of effective targeted therapies, that hold out hope for personalized therapy. However, the new drugs available to date are still an adjunct to conventional therapy, which is known to be toxic in the short and long term. The purpose of this review is to summarize recent advances in understanding the pathogenesis of the disease and discuss the results obtained from the use of new targeted drugs, with a look at future therapies that may be used in the absence of the current standard of care or may even cure this serious systemic autoimmune disease.

Lorenzo-Vizcaya A, Isenberg DA. Clinical trials in systemic lupus erythematosus: the dilemma-Why have phase III trials failed to confirm the promising results of phase II trials? Ann Rheum Dis 2023; 82:169-174.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune rheumatic disease of unknown aetiology, characterised by the production of auto-antibodies and formation of immune complexes against self-antigens and complement activation. This inflammatory response can lead to tissue infiltration and eventually, to organ damage.Patients with SLE invariably have periods of relapse and remission. Flares can occur even when the patient is on seemingly adequate treatment, which suggests that more effective therapies are necessary for the management of SLE. Thus, trials with many drugs against different targets, such as CD22, IL-12 and IL-23 or tyrosine kinases, have been carried out in recent years.A frustrating feature of some of the biologic drugs used to treat SLE has been the reporting of successful phase II trials followed by failures of the phase III trials.In this review, we will focus on phase II and III trials carried out with epratuzumab (anti CD22), baricitinib (Janus kinases inhibitor), rigerimod (P140 peptide) and ustekinumab (IL-12 and IL-23 inhibitor) and consider the reasons for their ultimate failure to 'make the grade'. Likewise, we will try to explain the possible reasons that can influence why good results may be obtained in phase II trials and lead to undue optimism.

CPT Pharmacometrics Syst Pharmacol 2022; 12:180-195.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease affecting multiple organ systems. Many investigational agents have failed or shown only modest effects when added to standard of care (SoC) therapy in placebo-controlled trials, and only two therapies have been approved for SLE in the last 60 years. Clinical trial outcomes have shown discordance in drug effects between clinical endpoints. Herein, we characterized longitudinal disease activity in the SLE population and the sources of variability by developing a latent disease trajectory model for SLE component endpoints (Systemic Lupus Erythematosus Disease Activity Index [SLEDAI], Physician's Global Assessment [PGA], British Isles Lupus Assessment Group Index [BILAG]) and composite endpoints (Systemic Lupus Erythematosus Responder Index [SRI], BILAG-based Composite Lupus Assessment [BICLA], and Lupus Low Disease Activity State [LLDAS]) using patient-level historical SoC data from nine phase II and III studies. Across all endpoints, in predictions up to 52 weeks from the final disease trajectory model, the following baseline covariates were associated with a greater decrease in SLE disease activity and higher response to placebo + SoC: Hispanic ethnicity from Central/South America, absence of hypocomplementemia, recent SLE diagnosis, and high baseline disease activity score using SLEDAI and BILAG separately. No discernible differences were observed in the trajectory of response to placebo + SoC across different SoC medications (antimalarial and immunosuppressant such as mycophenolate, methotrexate, and azathioprine). Across all endpoints, disease trajectory showed no difference in Asian versus non-Asian patients, supporting Asia-inclusive global SLE drug development. These results describe the first population approach to support a model-informed drug development framework in SLE.

Scoring personalized molecular portraits identify Systemic Lupus Erythematosus subtypes and predict individualized drug responses, symptomatology and disease progression. Brief Bioinform 2022; 23:bbac332. [PMID: 35947992 PMCID: PMC9487588 DOI: 10.1093/bib/bbac332] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 07/04/2022] [Accepted: 07/21/2022] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVES Systemic Lupus Erythematosus is a complex autoimmune disease that leads to significant worsening of quality of life and mortality. Flares appear unpredictably during the disease course and therapies used are often only partially effective. These challenges are mainly due to the molecular heterogeneity of the disease, and in this context, personalized medicine-based approaches offer major promise. With this work we intended to advance in that direction by developing MyPROSLE, an omic-based analytical workflow for measuring the molecular portrait of individual patients to support clinicians in their therapeutic decisions. METHODS Immunological gene-modules were used to represent the transcriptome of the patients. A dysregulation score for each gene-module was calculated at the patient level based on averaged z-scores. Almost 6100 Lupus and 750 healthy samples were used to analyze the association among dysregulation scores, clinical manifestations, prognosis, flare and remission events and response to Tabalumab. Machine learning-based classification models were built to predict around 100 different clinical parameters based on personalized dysregulation scores. RESULTS MyPROSLE allows to molecularly summarize patients in 206 gene-modules, clustered into nine main lupus signatures. The combination of these modules revealed highly differentiated pathological mechanisms. We found that the dysregulation of certain gene-modules is strongly associated with specific clinical manifestations, the occurrence of relapses or the presence of long-term remission and drug response. Therefore, MyPROSLE may be used to accurately predict these clinical outcomes. CONCLUSIONS MyPROSLE (https://myprosle.genyo.es) allows molecular characterization of individual Lupus patients and it extracts key molecular information to support more precise therapeutic decisions.

Abstract
IntroductionChildhood systemic lupus erythematosus (cSLE) is a complex multisystem autoimmune disease. In 2019, belimumab was approved for the clinical treatment for cSLE, making it the only biological agent approved for cSLE children aged 5 and older in 60 years.ObjectiveTo review emerging evidence on belimumab in cSLE published up to April 2022, so as to provide information for clinical decision-making.MethodA comprehensive search of relevant publications up to the date of April 2022 in PUBMED, EMBASE, WOS, COCHRANE, ClinicalTrials.gov, CBM, CNKI and WANFANG was performed using the following criteria: (a) English and Chinese language studies; (b) RCT studies, cohort studies, or case-control studies; (c) patients with age <18; (d) Observational studies or case series studies contain more than 5 patients. All relevant literature was independently screened and reviewed by at least two reviewers and the obtained literature data were extracted and reviewed by two authors.ResultsFive publications met the inclusion/exclusion criteria for cSLE: one randomized controlled trial, one retrospective cohort study, and three case series. There was a high degree of heterogeneity among several studies, and the availability of baseline and outcome data provided was uneven.ConclusionAt present, there is a lack of high-quality clinical trials of belimumab in the treatment of cSLE. Based on the current research, it is believed that the use of belimumab can inhibit cSLE activity, reduce the dose of corticosteroids and immunosuppressants, and delay kidney damage. Also it shows clinical benefit in alleviating symptoms of monogenic cSLE refractory to standard therapy. More studies are urgently needed to validate the clinical efficacy of belimumab in cSLE and to evaluate its long-term safety in pediatric populations to promote evidence-based practice.

Abstract
Objective To evaluate the prediction and effect of fibrinogen‐to‐albumin ratio (FAR) on active, severe active, and poor prognosis of systemic lupus erythematosus (SLE). Methods One hundred and sixty‐eight patients with SLE who were treated in our hospital were enrolled, the clinical data, laboratory indexes, and disease prognosis of all patients were collected and analyzed. Results Triglyceride (TG), FAR, ESR, and anti‐dsDNA (+) were the influencing factors, while complement 3 (C3) was the protective factor of active SLE, the odds ratio (OR) values were 2.968, 3.698, 2.114, 2.727, and 0.652, respectively (p < 0.05). FAR, ESR, and anti‐dsDNA (+) were the influencing factors, while C3 was the protective factor of severe active SLE, the OR values were 3.791, 1.953, 2.187, and 0.742, respectively (p < 0.05). SLE disease activity index (SLEDAI), TG, FAR, and anti‐dsDNA (+) were the influencing factors, while C3 was the protective factor of poor prognosis SLE, the OR values were 3.024, 2.293, 3.012, 2.323, and 0.801, respectively (p < 0.05). FAR and FIB were positively correlated with SLEDAI, while ALB was negatively correlated with SLEDAI, the related coefficient (r) were 0.398, 0.267, −0.270, respectively. The receiver operating curve (ROC) analysis showed that the predictive values of FAR for active, severe active and poor prognosis SLE were 0.769, 0.769, and 0.734, respectively, were significant higher than FIB and ALB (p < 0.05). Conclusion Fibrinogen‐to‐albumin ratio was an influencing factor of active, severe active, and poor prognosis SLE had higher predictive value than FIB and ALB for the activity and prognosis of SLE.

Abstract
Objectives To analyze the relative factors of improvement in disease activity (IDA) after first hospitalized treatment based on the systemic lupus erythematosus disease activity index (SLEDAI). Methods A total of 1069 adult systemic lupus erythematosus (SLE) patients who were hospitalized for the first time in 26 hospitals in Jiangsu Province from 1999 to 2009 were retrospectively analyzed. SLEDAI decrease ≥ 4 during hospitalization was identified as IDA. Relative factors of IDA were assessed by univariate and multivariate logistic regression. Results A total of 783 (73.2%) adult SLE patients showed IDA after the first hospitalization, while the remaining patients (n = 286) were in the non-IDA group. The IDA group had higher SLEDAI at admission; fewer patients had SLICC/ACR damage index (SDI) ≥ 1, comorbidities at admission, especially Sjögren’s syndrome, abnormal serum creatinine, and glomerular filtration rate. More patients had mucocutaneous and musculoskeletal involvements, leukopenia, increased C-reactive protein, anti-dsDNA antibody positive, and hypocomplementemia at admission and were treated with methotrexate and leflunomide during hospitalization. After multivariate logistic regression analysis, SDI ≥ 1 (P = 0.005) and combined with Sjögren’s syndrome (P < 0.001) at admission had negative association with IDA. Musculoskeletal involvement (P < 0.001), anti-dsDNA antibody positive (P = 0.012), hypocomplementemia (P = 0.001), and use of leflunomide (P = 0.030) were significantly related with IDA. Conclusion Organ damage or comorbidities at admission were adverse to SLE improvement. Anti-dsDNA antibody positive, hypocomplementemia, musculoskeletal involvements, and leflunomide treatment had positive association with IDA of SLE.
Key Points • Organ damage or comorbidities at admission were negatively correlated with SLE improvement. • Anti-dsDNA antibody positivity, hypocomplementemia, musculoskeletal involvements, and leflunomide treatment were positively associated with SLE improvement. |

Long-Term Clinical Outcome in Systemic Lupus Erythematosus Patients Followed for More Than 20 Years: The Milan Systemic Lupus Erythematosus Consortium (SMiLE) Cohort. J Clin Med 2022; 11:jcm11133587. [PMID: 35806873 PMCID: PMC9267338 DOI: 10.3390/jcm11133587] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 05/31/2022] [Accepted: 06/16/2022] [Indexed: 12/14/2022] Open
Abstract
Tackling active disease to prevent damage accrual constitutes a major goal in the management of patients with systemic lupus erythematosus (SLE). Patients with early onset disease or in the early phase of the disease course are at increased risk of developing severe manifestations and subsequent damage accrual, while less is known about the course of the disease in the long term. To address this issue, we performed a multicentre retrospective observational study focused on patients living with SLE for at least 20 years and determined their disease status at 15 and 20 years after onset and at their last clinical evaluation. Disease activity was measured through the British Isles Lupus Assessment Group (BILAG) tool and late flares were defined as worsening in one or more BILAG domains after 20 years of disease. Remission was classified according to attainment of lupus low-disease-activity state (LLDAS) criteria or the Definitions Of Remission In SLE (DORIS) parameters. Damage was quantitated through the Systemic Lupus Erythematosus International Collaborating Clinics/American College of Rheumatology damage index (SLICC/ACR-DI). LLAS/DORIS remission prevalence steadily increased over time. In total, 84 patients had a late flare and 88 had late damage accrual. Lack of LLDAS/DORIS remission status at the 20 year timepoint (p = 0.0026 and p = 0.0337, respectively), prednisone dose ≥ 7.5 mg (p = 9.17 × 10−5) or active serology (either dsDNA binding, low complement or both; p = 0.001) were all associated with increased late flare risk. Late flares, in turn, heralded the development of late damage (p = 2.7 × 10−5). These data suggest that patients with longstanding SLE are frequently in remission but still at risk of disease flares and eventual damage accrual, suggesting the need for tailored monitoring and therapeutic approaches aiming at effective immunomodulation besides immunosuppression, at least by means of steroids.

Abstract
Mixed outcome endpoints that combine multiple continuous and discrete components are often employed as primary outcome measures in clinical trials. These may be in the form of co-primary endpoints, which conclude effectiveness overall if an effect occurs in all of the components, or multiple primary endpoints, which require an effect in at least one of the components. Alternatively, they may be combined to form composite endpoints, which reduce the outcomes to a one-dimensional endpoint. There are many advantages to joint modeling the individual outcomes, however in order to do this in practice we require techniques for sample size estimation. In this article we show how the latent variable model can be used to estimate the joint endpoints and propose hypotheses, power calculations and sample size estimation methods for each. We illustrate the techniques using a numerical example based on a four-dimensional endpoint and find that the sample size required for the co-primary endpoint is larger than that required for the individual endpoint with the smallest effect size. Conversely, the sample size required in the multiple primary case is similar to that needed for the outcome with the largest effect size. We show that the empirical power is achieved for each endpoint and that the FWER can be sufficiently controlled using a Bonferroni correction if the correlations between endpoints are less than 0.5. Otherwise, less conservative adjustments may be needed. We further illustrate empirically the efficiency gains that may be achieved in the composite endpoint setting.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder that has detrimental effects on patient’s health-related quality of life (HRQoL). Owing to its immense heterogeneity of symptoms and its complexity regarding comorbidity burden, management of SLE necessitates interdisciplinary care, with the goal being the best possible HRQoL and long-term outcomes. Current definitions of remission, low disease activity, and response to treatment do not incorporate self-reported patient evaluation, while it has been argued that the physician’s global assessment should capture the patient’s perspective. However, even the judgment of a very well-trained physician might not replace a patient-reported outcome measure (PROM), not only owing to the multidimensionality of self-perceived health experience but also since this notion would constitute a direct contradiction to the definition of PROMs. The proper use of PROMs is not only an important conceptual issue but also an opportunity to build bridges in the partnership between patients and physicians. These points of consideration adhere to the overall framework that there will seldom be one single best marker that helps interpret the activity, severity, and impact of SLE at the same time. For optimal outcomes, we not only stress the importance of the use of PROMs but also emphasize the urgency of adoption of the conception of forming alliances with patients and facilitating patient participation in surveillance and management processes. Nevertheless, this should not be misinterpreted as a transfer of responsibility from healthcare professionals to patients but rather a step towards shared decision-making.

Abstract
BACKGROUND Composite responder endpoints feature frequently in rheumatology due to the multifaceted nature of many of these conditions. Current analysis methods used to analyse these endpoints discard much of the data used to classify patients as responders and are therefore highly inefficient, resulting in low power. We highlight a novel augmented methodology that uses more of the information available to improve the precision of reported treatment effects. Since these methods are more challenging to implement, we developed free, user-friendly software available in a web-based interface and as R packages. The software consists of two programs: one that supports the analysis of responder endpoints; the second that facilitates sample size estimation. We demonstrate the use of the software to conduct the analysis with both the augmented and standard analysis method using the MUSE study, a phase IIb trial in patients with systemic lupus erythematosus. RESULTS The software outputs similar point estimates with smaller confidence intervals for the odds ratio, risk ratio and risk difference estimators using the augmented approach. The sample size required in each arm for a future trial using the novel approach based on the MUSE data is 50 versus 135 for the standard method, translating to a reduction in required sample size of approximately 63%. CONCLUSIONS We encourage trialists to use the software demonstrated to implement the augmented methodology in future studies to improve efficiency.

Rheumatology (Oxford) 2021; 60:5854-5862.

Abstract
OBJECTIVES The randomized, double-blind, phase 2 b MUSE study evaluated the efficacy and safety of the type I IFN receptor antibody anifrolumab (300 mg or 1000 mg every 4 weeks) compared with placebo for 52 weeks in patients with chronic, moderate to severe SLE. Characterizing the exposure-response relationship of anifrolumab in MUSE will enable selection of its optimal dosage regimen in two phase 3 studies in patients with SLE. METHODS The exposure-response relationship, pharmacokinetics (PK) and SLE Responder Index (SRI(4)) efficacy data were analysed using a population approach. A dropout hazard function was also incorporated into the SRI(4) model to describe the voluntary patient withdrawals during the 1-year treatment period. RESULTS The population PK model found that type I IFNGS-high patients, and patients with a higher body weight, had significantly greater clearance of anifrolumab. Stochastic clinical simulations demonstrated that doses <300 mg would lead to a greater-than-proportional reduction in drug exposure owing to type I IFN alpha receptor-mediated drug clearance (antigen-sink effect, more rapid drug clearance at lower concentrations) and suboptimal SRI(4) responses with wider confidence intervals. CONCLUSIONS Based on PK, efficacy and safety considerations, anifrolumab 300 mg every 4 weeks was recommended as the optimal dosage for pivotal phase 3 studies in patients with SLE.

Abstract
OBJECTIVE The systemic lupus erythematosus (SLE) symptom checklist (SSC) is a patient-reported outcome measure consisting of 38 queries. We translated SSC into Japanese and attempted to validate its usefulness for evaluating the quality of life (QOL) of SLE patients and identify factors that affect QOL. METHODS Data from the Medical Outcomes Study Short-form 36 questionnaire (SF-36), Japanese LupusPRO, the Japanese version of the SSC (SSC-J) questionnaire, SLEDAI-2k, and the physician global assessment (PGA) were obtained on the same day from 226 SLE outpatients of the Kyoto Lupus cohort at Kyoto University Hospital. Relationships between the total scores or each item of SSC-J and SF-36, Japanese LupusPRO, SLEDAI-2k, or PGA were analyzed by Spearman's rank test. RESULTS The total scores of SSC-J correlated with the scores of SF-36 and Japanese LupusPRO. In each item of SSC-J, all 38 items correlated with the physical component summary and mental component summary of SF-36 as well as the Health-Related QOL (HRQOL) scores of Japanese LupusPRO, but not with the non-HRQOL of LupusPRO. SSC-J scores correlated with age, PGA, and corticosteroid doses, but not with SLEDAI-2k. CONCLUSIONS SSC-J is suitable as a disease-specific QOL assessment tool for SLE.

Abstract
OBJECTIVES No immunomodulatory drug has been approved for primary Sjögren's syndrome, a systemic autoimmune disease affecting 0.1% of the population. To demonstrate the efficacy of targeting interleukin 6 receptor in patients with Sjögren's syndrome-related systemic complications. METHODS Multicentre double-blind randomised placebo-controlled trial between 24 July 2013 and 16 July 2018, with a follow-up of 44 weeks, involving 17 referral centres. Inclusion criteria were primary Sjögren's syndrome according to American European Consensus Group criteria and score ≥5 for the EULAR Sjögren's Syndrome Disease activity Index (ESSDAI, score of systemic complications). Patients were randomised to receive either 6 monthly infusions of tocilizumab or placebo. The primary endpoint was response to treatment at week 24. Response to treatment was defined by the combination of (1) a decrease of at least 3 points in the ESSDAI, (2) no occurrence of moderate or severe activity in any new domain of the ESSDAI and (3) lack of worsening in physician's global assessment on a Visual Numeric Scale ≥1/10, all as compared with enrolment. RESULTS 110 patients were randomised, 55 patients to tocilizumab (mean (SD) age: 50.9 (12.4) years; women: 98.2%) and 55 patients to placebo (54.8 (10.7) years; 90.9%). At 24 weeks, the proportion of patients meeting the primary endpoint was 52.7% (29/55) in the tocilizumab group and 63.6% (35/55) in the placebo group, for a difference of -11.4% (95% credible interval -30.6 to 9.0) (Pr[Toc >Pla]=0.14). CONCLUSION Among patients with primary Sjögren's syndrome, the use of tocilizumab did not improve systemic involvement and symptoms over 24 weeks of treatment compared with placebo. TRIAL REGISTRATION NUMBER NCT01782235.

Abstract
Composite endpoints that combine multiple outcomes on different scales are common in clinical trials, particularly in chronic conditions. In many of these cases, patients will have to cross a predefined responder threshold in each of the outcomes to be classed as a responder overall. One instance of this occurs in systemic lupus erythematosus, where the responder endpoint combines two continuous, one ordinal and one binary measure. The overall binary responder endpoint is typically analysed using logistic regression, resulting in a substantial loss of information. We propose a latent variable model for the systemic lupus erythematosus endpoint, which assumes that the discrete outcomes are manifestations of latent continuous measures and can proceed to jointly model the components of the composite. We perform a simulation study and find that the method offers large efficiency gains over the standard analysis, the magnitude of which is highly dependent on the components driving response. Bias is introduced when joint normality assumptions are not satisfied, which we correct for using a bootstrap procedure. The method is applied to the Phase IIb MUSE trial in patients with moderate to severe systemic lupus erythematosus. We show that it estimates the treatment effect 2.5 times more precisely, offering a 60% reduction in required sample size.

Abstract
A few decades ago, the therapy goal of patients with systemic lupus erythematosus (SLE) was survival and the prevention of organ failure. Today, clinical remission and low disease activity are believed to be the optimal therapeutic targets. These aims are difficult to reach for many patients, but they still do not address the health-related quality of life (QoL) that is significantly impaired in SLE patients. Even in the state of remission, QoL and fatigue are insufficient controlled. Thus, patient-oriented research is essential to design new strategies for the management of lupus patients. The INTEGRATE project analyses the patients' and physicians' perspectives to pave the way to design an innovative therapeutic strategy for lupus and focuses on the multifaceted dimensions of the disease burden. Shared decision making (SDM) could include the patient's perspective of SLE to treatment strategy and consider QoL and the burden of lupus into the process of therapy decision.

Abstract
INTRODUCTION The type 1 interferon pathway is known to play a role in the immunopathology of systemic lupus erythematosus (SLE). As a result, biologic agents targeting this pathway have been developed and are currently being investigated in clinical trials. AREAS COVERED We review the biologic agents which have been developed to antagonize type I interferons in SLE. We focus on anifrolumab, a type I interferon receptor antagonist, and consider the complexities of defining efficacy in SLE clinical trials. EXPERT OPINION Anifrolumab shows promise as an addition to the SLE therapeutic armamentarium. Despite discordant results between its two phase III studies, there is a convincing suggestion of benefit in both trials to encourage the view that this approach might be effective. Data acquired thus far look particularly useful for cutaneous disease. We await data on its effect on renal, pulmonary, cardiac, and central nervous system involvement, on patient reported outcomes, and its safety and efficacy with long-term use.

Abstract
OBJECTIVE The pain Numeric Rating Scale (NRS) score became standard when pain was introduced as the fifth vital sign in the 1990s. Although plagued with issues, it remains the basis for primary outcome measures in clinical trials for chronic pain therapies. Multidimensional composite scoring that considers all aspects of the chronic pain experience may provide a more meaningful response measure. Herein we propose a multidimensional responder index. MATERIALS AND METHODS Data were extracted from an ongoing prospective, multicenter study on DeRidder Burst spinal cord stimulation (B-SCS) for chronic back and/or leg pain (NCT03082261). The analysis cohort consisted of subjects who completed the NRS, Pain Catastrophizing Scale (PCS), EuroQol-5D (EQ-5D), and eight-item Patient-Reported Outcomes Measurement Information System Physical Function preoperatively and at 12 months after implant. RESULTS A principal component analysis showed that each of the four measures contributed equally to the variance in the data set, confirming that pain score should not be used alone. Subjects who failed to respond on NRS responded on both PCS and EQ-5D. Eighty-one percent of subjects responded on at least two measures. The responder algorithm yielded an 84% success rate at both 6- and 12-month time points. CONCLUSIONS Our study suggests that therapeutic response, similar to the chronic pain experience, is multidimensional. Careful consideration should be made to incorporate composite endpoints in future SCS clinical trials.

Abstract
The development of biological therapies has had an impact on the management of several medical conditions. Their use in systemic lupus erythematosus (SLE), however, remains very limited. This review has summarized the evidence on the clinical effect of biologicals in SLE. Biological drugs with a number of targets have been studied in several phase II and III randomized controlled trials (RCTs). Positive results have been obtained in phase III RCTs with belimumab and this led to its license for active SLE. The clinical experience with belimumab has confirmed the efficacy and safety of belimumab in SLE. Promising results have been noted in phase II trials for blisibimod, sifalimumab, anifrolumab, and ustekinumab. Despite the fact that the RCTs with rituximab did not achieve their primary endpoint, clinical experience with rituximab is extensive and shows favorable clinical response in refractory renal and non-renal SLE. It is hoped that further ongoing phase III RCTs on a number of biological agents in SLE will highlight the potential role of other biologicals in the management of this challenging and heterogeneous condition.

Abstract
Systemic lupus erythematosus (SLE) is one of the most serious autoimmune diseases, characterized by highly diverse clinical manifestations. A biomarker is still needed for accurate diagnostics. SLE serum autoantibodies were discovered and validated using serum samples from independent sample cohorts encompassing 306 participants divided into three groups, i.e. healthy, SLE patients, and other autoimmune-related diseases. To discover biomarkers for SLE, a phage displayed random peptide library (Ph.D. 12) and deep sequencing were applied to screen specific autoantibodies in a total of 100 serum samples from 50 SLE patients and 50 healthy controls. A statistical analysis protocol was set up for the identification of peptides as potential biomarkers. For validation, 10 peptides were analyzed using enzyme-linked immunosorbent assays (ELISA). As a result, four peptides (SLE2018Val001, SLE2018Val002, SLE2018Val006, and SLE2018Val008) were discovered with high diagnostic power to differentiate SLE patients from healthy controls. Among them, two peptides, i.e. SLE2018Val001 and SLE2018Val002, were confirmed between SLE with other autoimmune patients. The procedure we established could be easily adopted for the identification of autoantibodies as biomarkers for many other diseases.

Performance of SLE responder index and lupus low disease activity state in real life: A prospective cohort study. Int J Rheum Dis 2019; 22:1752-1761. [PMID: 31379114 DOI: 10.1111/1756-185x.13663] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Revised: 06/18/2019] [Accepted: 06/25/2019] [Indexed: 12/31/2022]
Abstract
OBJECTIVE To prospectively assess the performance of the systemic lupus erythematosus (SLE) responder index (SRI) and the lupus low disease activity state (LLDAS) in a cohort-based, "real-life" clinical setting. METHODS One hundred and thirty-one consecutive patients with SLE were subdivided into two groups based on the need or not to escalate their immune suppressive treatment. Clinimetrics including physician global assessment scale (PGA), SLE Disease Activity Index 2000 (SLEDAI-2K), European Consensus Lupus Activity Measurement index (ECLAM) and British Isles Lupus Assessment Group index (BILAG) 2004 version were measured at baseline and at 6 and 12 months, together with laboratory data and treatment changes. LLDAS and SRI were calculated at each time point. RESULTS Lupus low disease activity state but not SRI-4 correlated with treatment de-escalation. Low disease activity attainment as estimated by LLDAS was more frequent in patients starting with lower SLEDAI-2K, whereas a decrease in SLEDAI score ≥ 4 points with < 0.3 increased PGA and no new grade A or more than one new grade B BILAG domains (SRI-4) was more frequent in patients with higher SLEDAI-2K and/or severe renal activity at baseline. Anti-DNA-positive patients were less likely to be in LLDAS at any time point. Serositis was associated with lack of LLDAS at baseline, but did not affect LLDAS achievement at 12 months. Normalizing complement levels heralded the achievement of LLDAS and SRI-4. CONCLUSION Lupus low disease activity state is a valuable tool for assessing response to treatment in the daily rheumatology practice. SRI might be less informative, at least in patients with low basal SLEDAI.

Abstract
OBJECTIVE To assess the responsiveness of clinical outcome measures in musculoskeletal SLE compared with US. METHODS A prospective pilot study was conducted in consecutive SLE patients with inflammatory musculoskeletal symptoms. Clinical assessments including SLEDAI, BILAG, 28 tender and swollen joint counts, physician and patient visual analogue scales (VAS), and US were performed at 0, 2 and 4 weeks following 120 mg i.m. methylprednisolone acetate. Responsiveness was analysed using changes and effect sizes using Cohen's criteria. RESULTS Twenty patients were recruited. Fifteen out of 20 had clinical swelling at baseline. All clinical and US parameters were significantly improved at week 4 (all P ⩽ 0.01). Musculoskeletal-BILAG score improved in 16/20. Musculoskeletal-SLEDAI improved in 7/20. SLE responder index 4 criteria were assessed in 19 patients with SLEDAI ⩾4 at baseline and were met in 9/19 at 4 weeks. Effect sizes at 4 weeks were large (>0.5) for US, physician VAS and BILAG, and medium (>0.3) for joint counts and SLEDAI. Large effect sizes for improvement in US grey-scale and power Doppler were observed in both SLE responder index 4 responders (r = -0.51 and -0.56, respectively) and non-responders (r = -0.62 and -0.59, respectively) at 4 weeks. CONCLUSION This is the first study to measure the responsiveness of clinical outcome measures in musculoskeletal SLE against an objective inflammation measure. BILAG and physician VAS were the most responsive clinical instruments. US was highly responsive in musculoskeletal SLE, while SLEDAI and joint counts appeared suboptimal for detection of improvement. These results suggest that clinical trials based on the SLEDAI and SLE responder index 4 may underestimate the efficacy of therapy in SLE.

Abstract
Patients with systemic lupus erythematosus frequently develop lupus nephritis (LN), a condition that can lead to end-stage kidney disease. Multiple serum and urine biomarkers for LN have been proposed in recent years, yet none have become incorporated into clinical use. The majority of studies have been single center with significant variability in cohorts, assays, and sample storage, leading to inconclusive results. It has become clear that no single biomarker is likely to be sufficient to diagnose LN, identify flares, and define the response to therapy and prognosis. A more likely scenario is a panel of urine, serum, tissue, and genetic biomarkers. In this review, we summarize traditional and novel biomarkers and discuss how they may be utilized in order to bring precision medicine to clinical practice in LN.

Abstract
BACKGROUND AND AIM Patients with Systemic Lupus Erythematosus (SLE) present increased cardiovascular mortality compared to the general population. Few studies have assessed the long-term development and progression of carotid atherosclerotic plaque in SLE patients. Our aim was to investigate the association of clinical and laboratory markers of disease activity and classical cardiovascular risk factors (CVRF) with carotid atherosclerosis development in SLE patients in a prospective 5-year study. METHODS AND RESULTS Clinical history and information on principal CVRFs were collected at baseline and after 5 years in 40 SLE patients (36 women, mean age 42 ± 9 years; 14.4 ± 7 years of mean disease duration) and 50 age-matched controls. Carotid Doppler ultrasonography was employed to quantify the atherosclerotic burden at baseline and at follow up. Clinimetrics were applied to assess SLE activity over time (SLEDAI). The association between basal circulating T cell subsets (including CD4+CCR5+; CD4+CXCR3+; CD4+HLADR+; CD4+CD45RA+RO-, CD4+CD45RO+RA- and their subsets) and atherosclerosis development was evaluated. During the 5-year follow up, 32% of SLE patients, developed carotid atherosclerosis compared to 4% of controls. Furthermore, considering SLEDAI changes over time, patients within the highest tertile were those with increased incidence of carotid atherosclerosis independently of CVRF. In addition, increased levels of CD4+CCR5+ T cells were independently associated with the development of carotid atherosclerosis in SLE patients. CONCLUSION Serial clinical evaluations over time, rather than a single point estimation of disease activity or CVRF burden, are required to define the risk of carotid atherosclerosis development in SLE patients. Specific T cell subsets are associated with long-term atherosclerotic progression and may further be of help in predicting vascular disease progression.

Abstract
Background Bevacizumab, an anti-VEGF monoclonal antibody, has recently emerged as a new option for severe forms of hereditary hemorrhagic telangiectasia (HHT). Its utilization in this orphan disease has rapidly spread despite the lack of randomized trials and international guidelines. The objective of this study is to report the main clinical data (baseline characteristics, dose schedule, efficacy, adverse events and deaths) of HHT patients treated by intravenous bevacizumab in France. Methods Retrospective observational study of HHT patients treated with bevacizumab for a severe form of the disease in the 14 centers of the French HHT network. Results Forty-six patients (median age: 68 years) were treated between March 2009 and May 2015. Ten patients were treated for high output cardiac failure, 20 patients for severe hemorrhages and 16 for both indications. The standard protocol (6 infusions of 5mg/kg every 2 weeks) was initially used in 89% of the cases but diverse strategies were subsequently applied. A clinical improvement was noted by the referent physician for 74% of the patients with a median effect’s duration of 6 months. Wound healing complications led to 2 amputations. Arthralgia/arthritis and arterial hypertension occurred in 5 patients each. One third of the patients were dead at the time of the final update, coherently with age and the poor prognosis of these highly symptomatic patients. Conclusion Intravenous bevacizumab seems to provide a clinical benefice in severe HHT patients. Precautions concerning wound healing and vascular pathologies must be respected. Prospective double blinded versus placebo trials are needed.

Abstract
Background The aim was to assess the attainability and outcome of the lupus low disease activity state (LLDAS) in the early stages of systemic lupus erythematosus (SLE). Methods LLDAS prevalence was evaluated at 6 (T1) and 18 (T2) months after diagnosis and treatment initiation (T0) in a monocentric cohort of 107 (median disease duration 9.7 months) prospectively followed Caucasian patients with SLE. Reasons for failure to achieve LLDAS were also investigated. Multivariate models were built to identify factors associated with lack of LLDAS achievement and to investigate the relationship between LLDAS and Systemic Lupus International Collaboration Clinics (SLICC)/Damage Index (SDI) accrual. Results There were 47 (43.9%) patients in LLDAS at T1 and 48 (44.9%) at T2. The most frequent unmet LLDAS criterion was prednisolone dose >7.5 mg/day (83% of patients with no LLDAS at T1). Disease manifestations with the lowest remission rate during follow up were increased anti-double-stranded DNA (persistently present in 85.7% and 67.5% of cases at T1 and T2, respectively), low serum complement fractions (73.2% and 66.3%) and renal abnormalities (46.4% and 28.6%). Renal involvement at T0 was significantly associated with failure to achieve LLDAS both at T1 (OR 7.8, 95% CI 1.4–43.4; p = 0.019) and T2 (OR 3.9, 95% CI 1.4–10.6; p = 0.008). Presence of any organ damage (SDI ≥1) at T2 was significantly associated with lack of LLDAS at T1 (OR 5.0, 95% CI 1.5–16.6; p = 0.009) and older age at diagnosis (OR 1.05 per year, 95% CI 1.01–1.09; p = 0.020). Conclusion LLDAS is a promising treatment target in the early stages of SLE, being attainable and negatively associated with damage accrual, but it fit poorly to patients with renal involvement.

Abstract
Therapeutic advances in systemic lupus erythematosus (SLE) are greatly needed. Despite advances in our knowledge of pathogenesis of the disease and targets, treatment remains a significant challenge. Finding effective and relatively safe medications remains one of the top priorities. SLE significantly impairs quality of life (QoL), and patient-reported outcomes (PROs) measure a unique aspect of the disease not captured by disease activity. Inclusion of PRO measurements is encouraged in SLE clinical trials, as they allow capturing benefits of a proposed intervention in language patients can relate to and in areas deemed pertinent and important to and by patients. Availability of patient-reported and patient-centric clinical trials data may facilitate patients in informed and shared decision making, and allow for comparative cost-effectiveness evaluation for future resource allocation and reimbursements. Herein we review clinical trials with biologic therapies wherein PRO tools were included in the study design.

Non-pathogenic tissue-resident CD8 + T cells uniquely accumulate in the brains of lupus-prone mice. Sci Rep 2017; 7:40838. [PMID: 28098193 PMCID: PMC5241651 DOI: 10.1038/srep40838] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Accepted: 12/13/2016] [Indexed: 11/08/2022] Open
Abstract
Severe lupus often includes psychiatric and neurological sequelae, although the cellular contributors to CNS disease remain poorly defined. Using intravascular staining to discriminate tissue-localized from blood-borne cells, we find substantial accumulation of CD8+ T cells relative to other lymphocytes in brain tissue, which correlates with lupus disease and limited neuropathology. This is in contrast to all other affected organs, where infiltrating CD4+ cells are predominant. Brain-infiltrating CD8+ T cells represent an activated subset of those found in the periphery, having a resident-memory phenotype (CD69+CD122−PD1+CD44+CD62L−) and expressing adhesion molecules (VLA-4+LFA-1+) complementary to activated brain endothelium. Remarkably, infiltrating CD8+ T cells do not cause tissue damage in lupus-prone mice, as genetic ablation of these cells via β2 m deficiency does not reverse neuropathology, but exacerbates disease both in the brain and globally despite decreased serum IgG levels. Thus, lupus-associated inflammation disrupts the blood-brain barrier in a discriminating way biased in favor of non-pathogenic CD8+ T cells relative to other infiltrating leukocytes, perhaps preventing further tissue damage in such a sensitive organ.
