Abstract
Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease characterised by the presence of autoantibodies towards nuclear antigens, immune complex deposition, and chronic inflammation at classic target organs such as skin, joints, and kidneys. Despite substantial advances in the diagnosis and management of SLE, the burden of disease remains high. It is important to appreciate the typical presentations and the diagnostic process to facilitate early referral and diagnosis for patients. In most patients, constitutional, mucocutaneous, and musculoskeletal symptoms represent the earliest complaints; these symptoms can include fatigue, lupus-specific rash, mouth ulcers, alopecia, joint pain, and myalgia. In this Seminar we will discuss a diagnostic approach to symptoms in light of the latest classification criteria, which include a systematic evaluation of clinical manifestations (weighted within each domain) and autoantibody profiles (such as anti-double-stranded DNA, anti-Sm, hypocomplementaemia, or antiphospholipid antibodies). Non-pharmacotherapy management is tailored to the individual, with specific lifestyle interventions and patient education to improve quality of life and medication (such as hydroxychloroquine or immunosuppressant) adherence. In the last decade, there have been a few major breakthroughs in approved treatments for SLE and lupus nephritis, such as belimumab, anifrolumab, and voclosporin. However the disease course remains variable and mortality unacceptably high. Access to these expensive medications has also been restricted across different regions of the world. Nonetheless, understanding of treatment goals and strategies has improved. We recognise that the main goal of treatment is the achievement of remission or low disease activity. Comorbidities due to both disease activity and treatment adverse effects, especially infections, osteoporosis, and cardiovascular disease, necessitate vigilant prevention and management strategies. Tailoring treatment options to achieve remission, while balancing treatment-related comorbidities, are priority areas of SLE management.

Abstract
Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE) and is one of the leading causes of morbidity and mortality in patients with SLE. It is estimated that up to 60% of individuals with SLE will develop LN, which can manifest at any stage of a patient's life; however, it commonly emerges early in the course of SLE and tends to exhibit a more aggressive phenotype in men compared to women. Black and Hispanic patients are more likely to progress to kidney failure than white patients. LN is characterized by kidney inflammation and chronic parenchymal damage, leading to impaired kidney function and potential progression to kidney failure. This article provides a comprehensive overview of the epidemiology, pathogenesis, clinical presentation, diagnosis, and management of LN, highlighting the importance of early recognition and treatment of LN to prevent progressive, irreversible kidney damage and improve patient outcomes. Additionally, the article discusses current and emerging therapies for LN, including traditional immunosuppressive agents, biological agents, and novel therapies targeting specific pathways involved in LN pathogenesis, to provide a practical guide for clinicians in properly diagnosing LN and determining a patient-centered treatment plan.

Abstract
OBJECTIVES Belimumab is a biological agent approved for the treatment of active lupus nephritis (LN), but its efficacy on refractory lupus nephritis (LN) is unknown. This study aims to evaluate the efficacy and safety of belimumab in Chinese patients with refractory LN. METHODS This multicenter, observational, and retrospective study enrolled patients with refractory LN who failed induction therapy with steroids, cyclophosphamide, mycophenolate, and calcineurin inhibitors and received 24-week belimumab treatment before data analysis. Treatment outcomes include the overall clinical response (physician judgment, disease activity, organ damage) and renal response (complete renal response, partial renal response, no renal response). Laboratory indices and adverse events were recorded as well. RESULTS Of the 45 patients enrolled in the study, 6 (13.3%) achieved complete renal response, 19 (42.2%) achieved partial renal response, and the overall renal response rate was 55.6%. Median rSLEDAI decreased from 12 (IQR 8-12) at baseline to 8 (IQR 4-8) (p < 0.0001), 4 (IQR 4-8) (p < 0.0001) at 12 and 24 weeks. Mean urinary protein decreased more than 50% from 3.2 g/24 h at baseline to 1.0 g/24 h at 24 weeks (p < 0.0001). The conditions of hypoalbuminemia and hypocomplementemia had also gradually improved. The levels of autoantibodies showed a significant downward trend. Additionally, 9 (20.0%) patients successfully reduced the dosage of prednisone to a safe range, and 3 of them achieved their treatment goal of prednisone cessation. The mean prednisone dosage decreased from 32.7 mg/day at baseline to 18.6 mg/day (p < 0.0001), 13.3 mg/day (p < 0.0001) at 12 and 24 weeks. There were 3 adverse events reported, including 2 cases of infection, and 1 case of allergy. No serious events occurred during the follow-up. CONCLUSIONS Belimumab is effective and safe when used in clinical practice, which can be considered as an add-on therapy for refractory LN. Key Points • A multicenter observational study in the real clinical settings of China. • First revealed the efficacy and safety of belimumab in Chinese patients with refractory LN.

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
Childhood-onset systemic lupus erythematosus is an inflammatory and autoimmune condition characterized by heterogeneous multisystem involvement and a chronic course with unpredictable flares. Kidney involvement, commonly called lupus nephritis, mainly presents with immune complex-mediated glomerulonephritis and is more frequent and severe in adults. Despite a considerable improvement in long-term renal prognosis, children and adolescents with lupus nephritis still experience significant morbidity and mortality. Moreover, current literature often lacks pediatric-specific data, leading clinicians to rely exclusively on adult therapeutic approaches. This review aims to describe pediatric lupus nephritis and provide an overview of the novel perspectives on the pathogenetic mechanisms, histopathological classification, therapeutic approach, novel biomarkers, and follow-up targets in children and adolescents with lupus nephritis.

Abstract
INTRODUCTION There is an unmet need to improve the efficacy of therapeutic regimens in lupus nephritis (LN). Cocktail immunosuppressive therapy for the synergistic effect of individual drugs may enhance efficacy and enable dosage reduction. However, the potential increase in the risk of serious and opportunistic infections is a concern. Moreover, the timing of combination therapy, adoption of a step-up or step-down approach, and the choice of drugs is still controversial, partly related to the cost-effectiveness issue. AREAS COVERED Evidence of a combination of conventional, newer immunosuppressive, and biologic/targeted agents in LN. EXPERT OPINION Early combination of conventional regimens with anti-B cell activation factor (anti-BAFF) or calcineurin inhibitors (CNIs) enhances the therapeutic effect without increasing serious adverse events in LN. However, combining anti-CD20 and anti-BAFF biologics appears to be less promising from the results of clinical trials. Initial combination strategy may be more cost-effective for patients at risk of treatment failure and renal function deterioration. With the availability of more options, the treat-to-target approach in LN is increasingly feasible and further studies are needed to compare the step-up and step-down approaches in the treatment of LN.

Abstract
IntroductionThe condition of refractory lupus nephritis (LN) negatively affects the prognosis and life expectancy of the patients, posing a challenge to manage in clinical. This interventional study evaluated the efficacy as well as safety of leflunomide in patients with refractory LN.MethodsTwenty patients with refractory LN were enrolled in this study. A daily dose of 20–40 mg of leflunomide was given to the patients orally. Meanwhile, immunosuppressives were withdrawn, and corticosteroids were gradually tapered. There was an average follow-up period of 3, 6, and 12 months for most patients while some were observed for as long as 24 months. We recorded biochemical parameters and side effects. We calculated the response rate using intention-to-treat analysis.ResultsEighteen patients (90%) completed the study. At 3 months, 80% (16/20) of the patients achieved more than a 25% decrease in 24-hour urine protein quantity. At 6 months, three patients (15%) achieved a partial response, and five patients (25%) achieved a complete response. However, by 12 months and 24 months, the complete response rate dropped to 15% and 20%, respectively. The objective responses were 30% (6/20), 40% (8/20), 40% (8/20), and 30% (6/20) at 3, 6, 12, and 24 months, respectively. Two patients withdrew from the study due to developing cytopenia and leucopenia.ConclusionIn patients diagnosed with refractory LN, our study shows that leflunomide could be a promising treatment option owing to its response rate and safety profile.

Abstract
ObjectivesIGU (IGU), a novel immunomodulatory agent for rheumatoid arthritis, has been shown to be effective and safe as monotherapy in a small population with refractory lupus nephritis (LN). The aim of this prospective study was to evaluate the efficacy and safety of IGU as an add-on therapy in patients with refractory LN in the context of clinical practice.MethodsThis is a single-arm observational study. We have enrolled LN patients since 2019 at Renji Hospital. All participants should have recurrent or refractory LN with at least one immunosuppressant (IS) and have a baseline urine protein/creatinine ratio (UPCR) >1.0. After enrollment, we added IGU (25 mg twice daily) to one of their previous immunosuppressants (IS) without increasing the dose of steroids. The primary outcome was the complete renal response (CRR) in the 6th month. UPCR decrease of over 50% was defined as partial response (PR). Extended follow-up was performed after the initial 6 months.ResultsWe enrolled 26 eligible participants. 11/26 patients had chronic kidney disease (CKD) stage 2/3 at the baseline. The IS combined with IGU included mycophenolate mofetil, tacrolimus, and cyclosporin A. No IS change was allowed. 80.7% of patients had baseline steroids less than 0.5mg/kg daily and there was no steroids escalation during the IGU treatment. The CRR rate was 42.3% (11/26) at month 6. With a median follow-up of 52 weeks (range: 23-116 weeks), the CRR rate at the last visit was 50% (13/26) and 73.1% (19/26) of patients had UPCR decrease of over 50%. Six patients withdrew, three for no response and three for renal flare after initial CRR. One patient had an estimated glomerular filtration rate worsening of over 20% and was classified as renal flare. Three mild to moderate adverse events were recorded.ConclusionsOur investigation merits further investigation in IGU as a potentially tolerable component of combination therapy for refractory LN.

Abstract
Lupus nephritis is a severe organ manifestation of systemic lupus erythematosus, and its pathogenesis involves complex etiology and mechanisms. Despite significant knowledge gains and extensive efforts put into understanding the development and relapsing disease activity, lupus nephritis remains a substantial cause of morbidity and mortality in lupus patients. Current therapies retain a significant unmet medical need regarding rates of complete response, preventing relapse of lupus nephritis, progression of chronic kidney disease to kidney failure, drug toxicity, and pill burden-related drug non-adherence. Connected to progression of chronic kidney disease are the associated risks for disabling or even lethal cardiovascular events, as well as chronic kidney disease-related secondary immunodeficiency and serious infections. In this regard, biomarkers are needed that can predict treatment response to specific drugs to enable personalized precision medicine. A series of clinical trials with innovative immunomodulatory drugs are ongoing and raise expectations for improvements in the management of lupus nephritis. Here, we review how new developments in pathogenesis connect with current and future perspectives for the management of lupus nephritis.

Abstract
INTRODUCTION Lupus nephritis (LN) is a key predictor for kidney failure and death in patients with systemic lupus erythematosus (SLE). While conventional immunosuppressive treatments have improved the outcome of LN, novel therapies continue to emerge. These new agents target specific immune-reactive cells (B cell repertoire or T lymphocytes) and crucial cytokines/signalling pathways in LN pathogenesis. AREAS COVERED New therapeutic approaches that target specific immune-reactive cells (B cell repertoire or T lymphocytes), crucial cytokines and their signalling pathways in LN pathogenesis. EXPERT OPINION Although earlier studies of rituximab fail to show benefit, a newer generation anti-CD20 biologic, obinutuzumab, is promising in LN. Inhibition of B-cell activating factor by belimumab confers superior renal response when added to the standard of care (SOC) regimens, leading to its recent approval for LN. Therapies targeting plasma cells (proteasome inhibitors, anti-CD38) in LN are being developed. A newer generation calcineurin inhibitor, voclosporin, when combined with SOC, results in better renal responses in LN. Other innovative strategies include targeting type I interferon, co-stimulatory signals, complement cascade (anti-C5b) and intracellular proliferation signals (e.g. mTOR, JAK1/2, BTK). While these novel agents improve the short-term renal responses without increased toxicities, long-term data on disease progression and safety remain to be established. Patient stratification by clinical phenotypes, biomarkers and molecular profiles helps enhance the efficacy and cost-effectiveness of novel therapies of LN.

Abstract
Systemic lupus erythematosus affects the kidneys in ~50% of all patients, and lupus nephritis (LN) is the most common manifestation of kidney involvement. Despite prompt diagnosis and treatment with aggressive immunosuppression, a significant proportion of LN patients do not respond to treatment and are considered to have refractory LN. Several factors other than drug resistance, such as nonadherence to treatment, undertreatment with conventional drugs, the effects of accumulated chronic damage, and genetic factors, may contribute to a poor response to treatment and should be considered. We define refractory LN as no change in (or worsening of) proteinuria and/or estimated glomerular filtration rate in response to 2 different standard-of-care induction regimens after 4-6 months in patients who are adherent to treatment. For patients who have LN that is truly refractory to standard of care, B cell-targeted therapy, specifically rituximab (RTX), is the most common next step. There is limited evidence available on alternative rescue therapies that may be used when there is no response to RTX. These include anti-CD38, leflunomide, intravenous immunoglobulin, plasma exchange, autologous stem cell transplantation, chimeric antigen receptor T cell therapy, anticomplement therapy, and interleukin-2 therapy.

Abstract
Approximately 70% of the patients with systemic lupus erythematosus will have clinical evidence of kidney damage during their evolution. Patients with impaired renal function at onset and those with recurrent flares have a poor prognosis. Understanding the mechanism of action of immunosuppressants is essential for proper prescription. Steroids inhibit the DNA sequence that promotes the release of inflammatory cytokines. Phosphoramide mustard, metabolite of cyclophosphamide, cross-link with the DNA, causing the aggregation of an alkyl group, causing cell death. Mycophenolate inhibits inosine monophosphate dehydrogenase, prevents de novo synthesis of guanine, inducing cell arrest in S phase. Azathioprine blocks the synthesis of purines and induces apoptosis. Calcineurin inhibitors prevent the dephosphorylation of NFAT and reduce the production of interleukin 2. Antimalarials alter the enzymatic release of lysosomes by increasing intravesicular pH. The mechanism of action of rituximab is related to complement-dependent cytotoxicity and the elimination of anti-CD20-labeled B cells. Progress in the knowledge and management of low doses of steroids may change the current paradigm and reduce the frequency of related adverse events. Mycophenolate seems to be a better choice than cyclophosphamide for induction, it is also preferred over azathioprine as a maintenance immunosuppressive agent, although azathioprine is preferred in women with a desire for conception, those pregnant, or with low resources. For treatment-resistant cases, tacrolimus, rituximab or belimumab may be effective. Ongoing clinical trials with new drugs offer promising results.

Long-Term Results of Triple Immunosuppression With Tacrolimus Added to Mycophenolate and Corticosteroids in the Treatment of Lupus Nephritis. Kidney Int Rep 2021; 7:516-525. [PMID: 35257064 PMCID: PMC8897290 DOI: 10.1016/j.ekir.2021.12.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 12/01/2021] [Accepted: 12/06/2021] [Indexed: 12/14/2022] Open
Abstract
Introduction Addition of a calcineurin inhibitor (CNI) to corticosteroids and mycophenolate increased the renal response rate in lupus nephritis (LN) because of proteinuria reduction, but there is little long-term efficacy and safety data on this triple immunosuppressive regimen. Methods This is a cohort study of patients with class III/IV/V LN whose proteinuria persisted despite initial standard therapy with mycophenolate mofetil (MMF) and prednisolone (PRED), in whom tacrolimus (TAC) was added (target 12-hour trough TAC plasma levels of 4–6 μg/l). Results A total of 22 patients with LN treated with triple immunosuppression were included, with follow-up of 61.1 ± 28.1 months. Achieved trough levels of TAC and mycophenolic acid (MPA) were 3.8 to 5.7 μg/l and 1.3 to 2.1 mg/l respectively. Significant proteinuria reduction occurred after 6 months and was sustained up to 5 years. Complete response (CR) and partial response (PR) rates at 12, 24, and 36 months was 59.1%, 72.7%, and 77.3% respectively. The slope of estimated glomerular filtration rate (eGFR) over time did not change after TAC was added. A total of 7 patients (31.8%) showed progressive chronic kidney disease (CKD). Two patients reached end-stage kidney disease during follow-up. Renal survival rate at -, 3, and 5 years was 100.0%, 95.0%, and 88.7% respectively. Two patients (9.1%) had renal relapse after 8.5 ± 0.7 months. A total of 5 patients (22.7%) showed worsening of hypertension, and 3 (13.6%) had worsened hyperlipidemia. Other key adverse events included infection (n = 16, 1 in 7 patient-years) and gastrointestinal upset (n = 6). Conclusion Triple immunosuppression with the addition of TAC to mycophenolate and PRED resulted in further proteinuria reduction and sustained disease quiescence in patients with LN whose proteinuria did not respond optimally to standard therapy.

Abstract
The recent updates on treatment recommendations for the management of systemic lupus erythematous have provided greater clarity in the way existing anti-inflammatory and immunomodulatory drugs are used, in treating disease activity, preventing flares, and reducing irreversible organ damage and toxicity arising from the treatments themselves. Novel therapies will provide more options in the armamentarium for treating this complex disease, but ongoing studies are needed to improve understanding of the optimal treatment algorithm to maintain quality of life and improve survival for patients.

Abstract
Objectives To analyse the current evidence for the management of lupus nephritis (LN) informing the 2019 update of the EULAR/European Renal Association-European Dialysis and Transplant Association recommendations. Methods According to the EULAR standardised operating procedures, a PubMed systematic literature review was performed, from January 1, 2012 to December 31, 2018. Since this was an update of the 2012 recommendations, the final level of evidence (LoE) and grading of recommendations considered the total body of evidence, including literature prior to 2012. Results We identified 387 relevant articles. High-quality randomised evidence supports the use of immunosuppressive treatment for class III and class IV LN (LoE 1a), and moderate-level evidence supports the use of immunosuppressive treatment for pure class V LN with nephrotic-range proteinuria (LoE 2b). Treatment should aim for at least 25% reduction in proteinuria at 3 months, 50% at 6 months and complete renal response (<500–700 mg/day) at 12 months (LoE 2a-2b). High-quality evidence supports the use of mycophenolate mofetil/mycophenolic acid (MMF/MPA) or low-dose intravenous cyclophosphamide (CY) as initial treatment of active class III/IV LN (LoE 1a). Combination of tacrolimus with MMF/MPA and high-dose CY are alternatives in specific circumstances (LoE 1a). There is low-quality level evidence to guide optimal duration of immunosuppression in LN (LoE 3). In end-stage kidney disease, all methods of kidney replacement treatment can be used, with transplantation having the most favourable outcomes (LoE 2b). Conclusions There is high-quality evidence to guide the initial and subsequent phases of class III/IV LN treatment, but low-to-moderate quality evidence to guide treatment of class V LN, monitoring and optimal duration of immunosuppression.

Abstract
Autoimmune diseases (AIDs) share similar serological, clinical, and radiological findings, but, behind these common features, there are different pathogenic mechanisms, immune cells dysfunctions, and targeted organs. In this context, multiple lines of evidence suggest the application of precision medicine principles to AIDs to reduce the treatment failure. Precision medicine refers to the tailoring of therapeutic strategies to the individual characteristics of each patient, thus it could be a new approach for management of AIDS which considers individual variability in genes, environmental exposure, and lifestyle. Precision medicine would also assist physicians in choosing the right treatment, the best timing of administration, consequently trying to maximize drug efficacy, and, possibly, reducing adverse events. In this work, the growing body of evidence is summarized regarding the predictive factors for drug response in patients with AIDs, applying the precision medicine principles to provide high-quality evidence for therapeutic opportunities in improving the management of these patients.

Abstract
Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease that represents a prodigious challenge of diagnosis and treatment. In 2019, under the leadership of the Chinese Rheumatology Association, a multidisciplinary guideline development group was established to develop an evidence-based diagnosis and treatment guideline for patients with SLE in PR China. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence and the strength of recommendations. The guideline was reported following the Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist. In this guideline, we provided recommendations for SLE classification criteria, disease activity monitoring and assessment, medication administration and considerations for SLE patients with organs and systems involved, and management of special populations such as SLE patients in the setting of pregnancy. This guideline serves as an evidence-based tool for Chinese clinicians to diagnose and treat patients with SLE.

Abstract
The inhibition of mesangial cell proliferation has become an important therapy for the prevention of glomerular proliferation‑associated diseases. The combined application of immunosuppressants with multiple targets presents a novel direction in the treatment of kidney diseases. The present study was designed to explore the inhibitory effects of tacrolimus (TAC) combined with mycophenolate mofetil (MMF) on the proliferation of mesangial cells based on the cell cycle. In vitro, the levels of the proliferation index markers, Ki67 and cyclin D1, in human mesangial cells (HMCs) were determined by immunofluorescence staining and western blot analysis, respectively. In mice with lupus nephritis (LN), the proliferation of mesangial cells was determined using PAS and Masson's trichrome staining, while immunohistochemistry was used to detect Ki67 and western blot analysis was employed for the evaluation of cyclin D1 levels. The expression of platelet‑derived growth factor (PDGF), a proliferation‑associated protein, was estimated using immunohistochemistry and western blot analysis. In patients with LN, Ki67, cyclin D1 and PDGF expression was estimated by immunohistochemistry. The transforming growth factor‑β1/Smad pathway influenced by TAC and the p38 pathway influenced by MMF were also examined by western blot analysis. The results suggested that the combination of TAC and MMF at half the concentration based on the cell cycle was more effective than monotherapy in inhibiting mesangial cell proliferation in vitro and in vivo. TAC inhibited HMC proliferation by affecting the Smad2 signaling pathway. MMF inhibited HMC proliferation by affecting the p38 signaling pathway. Combined treatment with TAC and MMF significantly improved the clinical indexes of patients with LN without severe adverse effects. On the whole, the findings of the present study validate and reinforce the potential use of the combination of TAC and MMF for the treatment of mesangial proliferative diseases.

Abstract
Lupus nephritis is an important cause of both acute kidney injury and chronic kidney disease that can result in end-stage renal disease. Its pathogenic mechanisms are characterized by aberrant activation of both innate and adaptive immune responses, dysregulation of inflammatory signaling pathways, and increased cytokine production. Treatment of lupus nephritis remains a challenging issue in the management of systemic lupus erythematosus since the clinical presentation, response to treatment, and prognosis all vary considerably between patients and are influenced by ethnicity, gender, the degree of chronic kidney damage, pharmacogenomics, and non-immunological modulating factors. Elucidation of the various immunopathogenic pathways in lupus nephritis has resulted in the development of novel therapies, including biologics that target specific antigens on B lymphocytes to achieve B cell depletion, agents that modulate B cell proliferation and development, drugs that block co-stimulatory pathways, drugs that target T lymphocytes primarily, and therapies that target complement activation, signaling pathways, pro-inflammatory cytokines, and neutrophil extracellular traps. This review will discuss recent advances in the understanding of disease pathogenesis in lupus nephritis in the context of potential emerging therapies.

Abstract
PURPOSE OF REVIEW Update on the diagnosis, treatment, and monitoring of lupus nephritis. RECENT FINDINGS The recent criteria enable the earlier classification of lupus nephritis based on kidney biopsy and compatible serology. Treatment of active nephritis includes low-dose intravenous cyclophosphamide or mycophenolate, followed by maintenance immunosuppression. Recent trials have suggested superiority of regimens combining mycophenolate with either calcineurin inhibitor or belimumab, although their long-term benefit/risk ratio has not been determined. Encouraging results with novel anti-CD20 antibodies confirm the effectiveness of B cell depletion. Achievement of low-grade proteinuria (< 700-800 mg/24 h) at 12-month post-induction is linked to favorable long-term outcomes and could be considered in a treat-to-target strategy. Also, repeat kidney biopsy can guide the duration of maintenance immunosuppression. Lupus nephritis has increased cardiovascular disease burden necessitating risk-reduction strategies. An expanding spectrum of therapies coupled with ongoing basic/translational research can lead to individualized medical care and improved outcomes in lupus nephritis.

Abstract
Objectives Iguratimod, a novel immunomodulatory agent for rheumatoid arthritis, has been shown to be effective against murine lupus. The aim of this study was to make a preliminary evaluation of the efficacy and safety of iguratimod as salvage therapy in patients with refractory lupus nephritis (LN). Methods We enrolled eligible patients with refractory LN, which we defined as having failed or relapsed on at least two immunosuppressant agents. After enrollment, we substituted iguratimod (25 mg twice daily) for their previous immunosuppressant agents without increasing the dose of steroids. The primary outcome was complete/partial remission (PR/CR) at week 24. Patients who achieved remission continued iguratimod as maintenance therapy over an extended follow-up. Results The study cohort comprised 14 patients with refractory LN, 10 of whom had recent treatment failure and 4 repeated relapses with inadequate initial responses. At enrollment, none of the patients had detectable evidence of extra-renal involvement. The median prednisone dosage was 10 mg/d (IQR 0–10 mg/day). Thirteen patients were eligible for response evaluation, with one patient missed. The renal response rate was 92.3% (12/13) at week 24, with 38.5% (5/13) achieving CR and 53.8% (7/13) achieving PR. We then continued to follow up the responding patients for up to 144 weeks. Twenty-five percent of the patients (3/12) had renal relapse after initial PR. The estimated glomerular filtration rate of all patients maintained stable during follow-up. One patient had a severe adverse reaction (anemia) but recovered fully after stopping iguratimod. Conclusions Our study supports the potential of iguratimod for treatment of refractory LN. Iguratimod could be a promising candidate drug for this condition.

Ann Rheum Dis 2020; 79:713-723. [PMID: 32220834 DOI: 10.1136/annrheumdis-2020-216924] [Citation(s) in RCA: 430] [Impact Index Per Article: 107.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2020] [Revised: 03/16/2020] [Accepted: 03/17/2020] [Indexed: 12/19/2022]
Abstract
OBJECTIVE To update the 2012 EULAR/ERA-EDTA recommendations for the management of lupus nephritis (LN). METHODS Following the EULAR standardised operating procedures, a systematic literature review was performed. Members of a multidisciplinary Task Force voted independently on their level of agreeement with the formed statements. RESULTS The changes include recommendations for treatment targets, use of glucocorticoids and calcineurin inhibitors (CNIs) and management of end-stage kidney disease (ESKD). The target of therapy is complete response (proteinuria <0.5-0.7 g/24 hours with (near-)normal glomerular filtration rate) by 12 months, but this can be extended in patients with baseline nephrotic-range proteinuria. Hydroxychloroquine is recommended with regular ophthalmological monitoring. In active proliferative LN, initial (induction) treatment with mycophenolate mofetil (MMF 2-3 g/day or mycophenolic acid (MPA) at equivalent dose) or low-dose intravenous cyclophosphamide (CY; 500 mg × 6 biweekly doses), both combined with glucocorticoids (pulses of intravenous methylprednisolone, then oral prednisone 0.3-0.5 mg/kg/day) is recommended. MMF/CNI (especially tacrolimus) combination and high-dose CY are alternatives, for patients with nephrotic-range proteinuria and adverse prognostic factors. Subsequent long-term maintenance treatment with MMF or azathioprine should follow, with no or low-dose (<7.5 mg/day) glucocorticoids. The choice of agent depends on the initial regimen and plans for pregnancy. In non-responding disease, switch of induction regimens or rituximab are recommended. In pure membranous LN with nephrotic-range proteinuria or proteinuria >1 g/24 hours despite renin-angiotensin-aldosterone blockade, MMF in combination with glucocorticoids is preferred. Assessment for kidney and extra-renal disease activity, and management of comorbidities is lifelong with repeat kidney biopsy in cases of incomplete response or nephritic flares. In ESKD, transplantation is the preferred kidney replacement option with immunosuppression guided by transplant protocols and/or extra-renal manifestations. Treatment of LN in children follows the same principles as adult disease. CONCLUSIONS We have updated the EULAR recommendations for the management of LN to facilitate homogenization of patient care.

Abstract
The introduction of biologic DMARDs into rheumatology has resulted in a substantial reduction of the burden of many rheumatic diseases. In the slipstream of the success achieved with these biologic DMARDs, some conventional immunosuppressive drugs have also found use in new indications. Notably, mycophenolate mofetil, azathioprine and tacrolimus have made their way from solid organ transplantation drugs to become useful assets in rheumatology practice. Mycophenolate mofetil and azathioprine inhibit the purine pathway and subsequently diminish cell proliferation. Both drugs have a pivotal role in the treatment of various rheumatic diseases, including lupus nephritis. Tacrolimus inhibits lymphocyte activation by inhibiting the calcineurin pathway. Mycophenolate mofetil and tacrolimus are, among other indications, increasingly being recognized as useful drugs in the treatment of interstitial lung disease in systemic rheumatic diseases and skin fibrosis in systemic sclerosis. A broad array of trials with mycophenolate mofetil, azathioprine and/or tacrolimus are ongoing within the field of rheumatology that might provide further novel avenues for the use of these drugs. In this Review, we discuss the historical perspective, pharmacodynamics, clinical indications and novel avenues for mycophenolate mofetil, azathioprine and tacrolimus in rheumatology.

Abstract
Previous studies have indicated that various drugs may be beneficial for the treatment of patients with refractory lupus nephritis (RLN). The present study aimed to evaluate the effectiveness and safety of common therapeutic drugs for the treatment of RLN using a network meta-analysis (NMA). NMA was performed using Stata 14.0 software. The odds ratio (OR) and 95% CI were calculated. A total of 19 studies comprising 1,127 patients were included. Common therapeutic drugs for RLN included glucocorticoids (GC), cyclophosphamide (CTX), mycophenolate mofetil (MMF), tacrolimus (TAC), leflunomide (LEF), cyclosporine A and rituximab (RTX). Evaluation of the effectiveness revealed that MMF + GC produced significantly higher overall responses (i.e. complete remission plus partial remission) and that MMF + GC (OR=2.58; 95% CI, 1.67–3.97), CTX + RTX + GC (OR=3.89; 95% CI, 1.60–9.45), CTX + LEF + GC (OR=3.05; 95% CI, 1.05–8.84) and CTX + TAC + GC (OR=6.22; 95% CI, 1.93–20.05) had significantly higher overall responses compared with those to the traditional treatment regimen (CTX + GC). Ranking probability based on the surface under the cumulative ranking curve indicated that CTX + TAC + GC had the highest probability (80.6%) of being the best treatment for achieving an overall response. In the safety evaluation, MMF + GC had a lower risk of infection than CTX + GC (OR=0.32; 95% CI, 0.11,0.88). There were no statistically significant differences in adverse reactions, including gastrointestinal reactions and leukopenia between any two treatment regimens. In conclusion, the regimen of CTX + TAC + GC exhibited a trend in superiority regarding clinical efficacy among common therapeutic drug treatments for RLN, while the regimen of CTX + GC had a higher probability to cause adverse effects among the nine interventions compared.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease with variable clinical expression. It is a potentially devastating condition affecting mostly women and leading to clinically unpredictable outcomes. Remission and flares may, in fact, alternate over time and a mild involvement limited to few articular sites may be followed by severe and widespread organ damage. SLE is the prototype of any autoimmune condition and has, for this reason, attracted the interest of basic immunologists. Therapies have evolved over time and clinical prognosis has, in parallel, been improved. What clinicians still lack is the possibility to use biomarkers of the disease as predictors of outcome and, in this area, several studies are trying to find solutions. Circulating autoantibodies are clearly a milestone of clinical research and the concrete possibility is to integrate, in the future, classical markers of activation (like C3) with target organ autoantibodies. Anti-dsDNA antibodies represent a basic point in any predictive attempt in SLE and should be considered the benchmark for any innovative proposal in the wide field of target organ pathologies related to SLE. DNA is part of the nucleosome that is the basic unit of chromatin. It consists of DNA wrapped around a histone octamer made of 2 copies each of Histone 2A, 2B, 3, and 4. The nucleosome has a plastic organization that varies over time and has the potential to stimulate the formation of antibodies directed to the whole structure (anti-nucleosome) or its parts (anti-dsDNA and anti-Histones). Here, we present an updated review of the literature on antibodies directed to the nucleosome and the nucleosome constituents, i.e., DNA and Histones. Wetriedto merge the data first published more than twenty years ago with more recent results to create a balanced bridge between old dogma and more recent research that could serve as a stimulus to reconsider mechanisms for SLE. The formation of large networks would provide the chance of studying large cohorts of patients and confirm what already presented in small sample size during the last years.

Abstract
Introduction: Due to the polymorphic clinical presentations and manifestations of systemic lupus erythematosus (SLE), biomarkers with enough diagnostic and prognostic value are of paramount importance. Recently, anti-double stranded DNA (anti-dsDNA) auto-antibodies have been proposed to monitor the response to different therapies. It has also been suggested that they should be employed as entry markers in trial studies. However, their clinical use remains still debated and, sometimes, controversial, due to conflicting findings reported. Areas covered: Through an extensive literature review, we evaluated changes in anti-dsDNA auto-antibodies levels before and after the administration of the treatment (either biological or non-biological). Expert opinion: Anti-dsDNA auto-antibodies related findings are still difficult to compare mainly because of the different detecting methods employed, even though in most studies included in this review a consistent decreasing pattern after the treatment seems to emerge. Hence, if properly standardized, anti-dsDNA auto-antibody profile may be a reliable biomarker to monitor the effectiveness of biologics as well as of non-biological drugs, especially if grouped in composite outcomes scores, such as the 'Lupus Multivariable Outcome Score' (LUMOS) or measured with other biomarkers, such as anti-nucleosome auto-antibodies. We recommend the assessment of anti-dsDNA auto-antibodies levels in both daily practice and research settings.

Abstract
The ideal therapeutic approach for lupus nephritis (LN) is to quickly achieve a complete remission and maintain that response long-term while minimizing drug toxicity, and prevent tissue damage and death. The combination therapy consisting of multiple medications is aimed at incorporating drugs with complementary actions at reduced doses to achieve additive or synergistic therapeutic effects while minimizing toxicity. Here, we review the available evidence using combination therapies (triple therapy) and how such strategies can improve therapeutic efficacy in LN, which will mainly focus on the combination of high-dose corticosteroids with mycophenolate mofetil (MMF) and a calcineurin inhibitor (CNI) at low dose. We discuss the rationale, efficacy, and safety of the therapy, as well as its molecular mechanisms. We also discuss the questions raised from the trials and briefly describe emerging approaches developed on the basis of combination therapy, and these advances that promise to improve on the standard-of-care treatments and toward individual therapy in LN.

Abstract
Background Children with lupus nephritis particularly, diffuse proliferative and membranous glomerulonephritis, may necessitate potent immunosuppressive medications and occasionally combined therapy. Objective To report the beneficial effects of tacrolimus (TAC) in children with refractory lupus nephritis from a single tertiary pediatric rheumatology clinic. Methods This is a retrospective case series of children with refractory lupus nephritis treated with TAC after failure of aggressive immunosuppressive treatment. All patients were evaluated at the time of initiation of TAC and at last follow-up visit by assessing the following response parameters: cSLE Disease Activity Index (SLEDAI), urine protein/creatinine ratio, urine sediments, serum albumin, complement (C3 and C4), anti-double-stranded DNA (dsDNA) antibody levels, and renal function assessed by glomerular filtration rate (eGFR). Results Three children (two girls and one boy) with lupus nephritis and persistent nephrotic-range proteinuria failed prednisone treatment as well as sequential treatment of cyclophosphamide, mycophenolate mofetil (MMF), and rituximab. When TAC was administered along with MMF and prednisone, all patients showed improvement in response parameters, namely, SLEDAI, serum albumin, and proteinuria, and prednisone doses were significantly weaned off and discontinued in two patients. However, eGFR remained stable during the treatment period. TAC was well tolerated, and no adverse effects were observed. Conclusion TAC combined with MMF can be considered as an alternative therapeutic option for children with refractory lupus nephritis particularly those with persistent nephrotic-range proteinuria.
