Abstract
BACKGROUND AND OBJECTIVES Acute kidney injury (AKI) is one of the most common and severe clinical syndromes of diffuse proliferative lupus nephritis (DPLN), of which poor prognosis is indicated by aggravated renal function deterioration. However, the specific therapy and mechanisms of AKI in DPLN remain to be explored. METHODS The correlation between AKI and clinical pathological changes in DPLN patients was analyzed. Expression of STAT3 signaling was detected in MRL/lpr mice with DPLN using immunohistochemical staining and immunoblotting. Inhibition of STAT3 activation by combination therapy was assessed in MRL/lpr mice. RESULTS Correlation analysis revealed only the interstitial leukocytes were significantly related to AKI in endocapillary DPLN patients. MRL/lpr mice treated with vehicle, which can recapitulate renal damages of DPLN patients, showed upregulation of STAT3, pSTAT3 and caspase-1 in renal cortex. FLLL32 combined with methylprednisolone therapy significantly inhibited the STAT3 activation, improved acute kidney damage, reduced the interstitial infiltration of inflammatory cells and decreased the AKI incidence in MRL/lpr mice. CONCLUSION STAT3 activation may play an important role in the pathogenesis of DPLN and the development of AKI. Hence, STAT3 inhibition based on the combination of FLLL32 with methylprednisolone may represent a new strategy for treatment of DPLN with AKI.

Abstract
The 2023 update of the EULAR recommendations for the management of systemic lupus erythematosus (SLE) faced several tasks: the newly approved medications anifrolumab and voclosporin as well as the additional approval of belimumab for lupus nephritis had to be conceptionally fitted into the management of SLE. Novel data on hydroxychloroquine and glucocorticoids, additional results for the treat-to-target goals remission and low disease activity and experience with respect to vaccinations and infections had to be considered. Additionally, EULAR specified a slightly modified structure. The update was further developed with 5 overarching principles and 13 recommendations. An SLE activity score is required for each patient visit. All SLE patients should receive hydroxychloroquine at a target dose of 5 mg/kg body weight. Glucocorticoids should only be used if necessary and reduced to not more than 5 mg prednisone equivalent daily in the long-term or, even better, tapered off. If the target of remission or low disease activity is not reached, methotrexate, azathioprine, mycophenolate and/or belimumab or anifrolumab should be used. For lupus nephritis, Euro-Lupus cyclophosphamide or mycophenolate are options for induction therapy and mycophenolate or azathioprine for maintenance. In the case of severe nephritis, the addition of belimumab or a calcineurin inhibitor (voclosporin or tacrolimus) should be considered. It is important that treatment should be continued for at least 3 years. This review article describes the details of the new recommendations against the background of relevant studies in recent years and classifies them in the clinical context.

Abstract
Head-to-head (H2H) studies enable the direct comparison of several alternative therapeutic approaches and thus provide the evidence-based foundation for the relative position of one treatment as compared to others for a specific indication. These trials constitute an important addition to placebo-controlled clinical trials. Among the controlled clinical trials not performed by the pharmaceutical industry, there are a relevant number of H2H trials for connective tissue diseases (CTDs) and vasculitides, particularly for systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). This article encompasses a review of the H2H trials for CTDs and vasculitides and discusses their relevance for current treatment algorithms. For SLE the H2H trials were predominantly performed for the treatment of lupus nephritis, demonstrating the impact of low-dose cyclophosphamide and mycophenolate as well as azathioprine for maintenance therapy. In recent H2H trials rituximab could be established as induction and maintenance therapy for AAV, which has now been incorporated into current treatment guidelines. Further comparative trials will be necessary in order to select the most effective and safest treatment for every patient, in the sense of personalized medicine.

Abstract
Systemic Lupus Erythematosus (SLE) and lupus nephritis treatment is still based on non-specific immune suppression despite the first biological therapy for the disease having been approved more than a decade ago. Intense basic and translational research has uncovered a multitude of pathways that are actively being evaluated as treatment targets in SLE and lupus nephritis, with two new medications receiving FDA approval in the last 3 years. Herein we provide an overview of targeted therapies for SLE including medications targeting the B lymphocyte compartment, intracellular signaling, co-stimulation, and finally the interferons and other cytokines.

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
BACKGROUND The purpose of the study was to develop a genotype-incorporated population pharmacokinetic (PPK) model of tacrolimus (TAC) in adults with systemic lupus erythematosus (SLE) to investigate the factors influencing TAC pharmacokinetics and to develop an individualized dosing regimen based on the model. In addition, a non-genotype-incorporated model was also established to assess its predictive performance compared to the genotype-incorporated model. METHODS A total of 365 trough concentrations from 133 adult SLE patients treated with TAC were collected to develop a genotype-incorporated PPK model and a non-genotype-incorporated PPK model of TAC using a nonlinear mixed-effects model (NONMEM). External validation of the two models was performed using data from an additional 29 patients. Goodness-of-fit diagnostic plots, bootstrap method, and normalized predictive distribution error test were used to validate the predictive performance and stability of the final models. The goodness-of-fit of the two final models was compared using the Akaike information criterion (AIC). The dosing regimen was optimized using Monte Carlo simulations based on the developed optimal model. RESULTS The typical value of the apparent clearance (CL/F) of TAC estimated in the final genotype-incorporated model was 14.3 L h-1 with inter-individual variability of 27.6%. CYP3A5 polymorphism and coadministered medication were significant factors affecting TAC-CL/F. CYP3A5 rs776746 GG genotype carriers had only 77.3% of the TAC-CL/F of AA or AG genotype carriers. Omeprazole reduced TAC-CL/F by 3.7 L h-1 when combined with TAC, while TAC-CL/F increased nonlinearly as glucocorticoid dose increased. Similar findings were demonstrated in the non-genotype-incorporated PPK model. Comparing these two models, the genotype-incorporated PPK model was superior to the non-genotype-incorporated PPK model (AIC = 643.19 vs. 657.425). Monte Carlo simulation based on the genotype-incorporated PPK model indicated that CYP3A5 rs776746 AA or AG genotype carriers required a 1/2-1 fold higher dose of TAC than GG genotype carriers to achieve the target concentration. And as the daily dose of prednisone increases, the dose of TAC required to reach the target concentration increases appropriately. CONCLUSIONS We developed the first pharmacogenetic-based PPK model of TAC in adult patients with SLE and proposed a dosing regimen based on glucocorticoid dose and CYP3A5 genotype according to the model, which could facilitate individualized dosing for TAC.

Abstract
OBJECTIVE The purpose of this study was to compare the efficacy and safety of tacrolimus and mycophenolate mofetil (MMF) as induction therapy and low-dose tacrolimus as treatment for lupus nephritis (LN). METHODS Meta-analysis of randomized controlled trials (RCTs) was conducted to compare the efficacy and safety of tacrolimus and MMF as induction therapy for LN. We systematically reviewed RCTs and prospective cohort studies with a tacrolimus dose of 3 mg daily and performed a meta-analysis of the efficacy and safety of tacrolimus as an induction treatment for LN in comparison to MMF. RESULTS The inclusion criteria were satisfied by eight studies (five RCTs and three prospective cohort studies) with a total of 408 individuals (289 for tacrolimus vs. MMF and 119 for low-dose tacrolimus). Tacrolimus and MMF had similar complete remission rates (odds ratio [OR] 1.028; 95% confidence interval [CI] 0.589-1.796; p = 0.922). The partial remission rate did not differ between the tacrolimus and MMF groups (OR 1.400; 95% CI 0.741-2.646; p = 0.300). Tacrolimus and MMF showed no differences in proteinuria, serum albumin, serum creatinine, creatinine clearance, renal Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), or extra-renal SLEDAI. The incidence of infection, severe infection, leukopenia, and hyperglycemia did not differ between the tacrolimus and MMF groups. However, herpes zoster infection was significantly less common in the tacrolimus group (OR 0.137; 95% CI 0.034-0.546; p = 0.005), whereas serum creatinine elevation was significantly higher in the tacrolimus group than in the MMF group (OR 8.148; 95% CI 1.369-48.50; p = 0.021). At 3 mg/d, tacrolimus was shown to be safe, well tolerated, and offered therapeutic benefits in all investigations. CONCLUSION Tacrolimus was comparable to MMF in terms of effectiveness and safety as an induction therapy for LN, with the exception of a reduced risk of herpes zoster infection and a rise in serum creatinine. In individuals with LN, 3 mg/d tacrolimus was proven to be efficacious and safe.

Abstract
OBJECTIVES This study aims to assess the risk of relapse after complete remission (CR) and partial remission (PR), and to develop a prognostic nomogram predicting the probability in lupus nephritis (LN) patients. METHODS Data from patients with LN who had been in remission were collected as a training cohort. The prognostic factors were analyzed using the univariable and multivariable Cox model for the training group. A nomogram was then developed using significant predictors in multivariable analysis. Both discrimination and calibration were assessed by bootstrapping with 100 resamples. RESULTS A total of 247 participants were enrolled, including 108 in the relapse group and 139 in the no relapse group. In multivariate Cox analysis, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), erythrocyte sedimentation rate (ESR), complement 1q (C1q), and antiphospholipid (aPL), anti-Sm antibody were found to be significant for predicting relapse rates. The prognostic nomogram including the aforementioned factors effectively predicted 1- and 3-year probability of flare-free. Moreover, a favorable consistency between the predicted and actual survival probabilities was demonstrated using calibration curves. CONCLUSIONS High SLEDAI, ESR, and positive aPL, anti-Sm antibody are potential risk factors for LN flare, while high C1q can reduce its recurrence. The visualized model we established can help predict the relapse risk of LN and aid clinical decision-making for individual patients.

Abstract
Calcineurin inhibitors (CNI) can suppress allo- and autoimmunity by suppressing T cell function but also have anti-proteinuric effects by stabilizing the cellular components of the kidney's filtration barrier. Therefore, CNI are used in autoimmune kidney diseases with proteinuria. However, the traditional CNI, cyclosporine A and tacrolimus, have a narrow therapeutic range, need monitoring of drug levels, and their use is associated with nephrotoxicity and metabolic alterations. Voclosporin (VOC), a novel CNI, no longer requires drug level monitoring and seems to lack these adverse effects, although hypertension and drug-drug interactions still occur. VOC demonstrated efficacy superior to standard-of-care in controlling active lupus nephritis in the phase 2 AURA-LV and the phase 3 AURORA-1 trials and was approved for the treatment of active lupus nephritis. However, how to implement VOC into the current and changing treatment landscape of lupus nephritis is still debated. Here, we review the unique chemistry, pharmacology, and toxicity profile of VOC, summarize the efficacy and safety data from the AURA-LV and AURORA-1 trials, and discuss the following four possible options to implement VOC into the management of lupus nephritis, namely regarding B cell-targeting therapy with belimumab (BEL). These include: 1. patient stratification to either VOC or BEL, 2. VOC/BEL combination therapy, 3. VOC-BEL sequential therapy, or 4. alternative options for the rapid antiproteinuric effect of VOC.

Abstract
PURPOSE OF REVIEW Discuss the prognostic significance of kidney flares in patients with lupus nephritis, associated risk factors, and possible preventative strategies. RECENT FINDINGS Recently performed clinical trials and observational cohort studies underscore the high frequency of relapses of kidney disease, following initial response, in patients with proliferative and/or membranous lupus nephritis. Analysis of hard disease outcomes such as progression to chronic kidney disease or end-stage kidney disease, coupled with histological findings from repeat kidney biopsy studies, have drawn attention to the importance of renal function preservation that should be pursued as early as lupus nephritis is diagnosed. In this respect, non-randomized and randomized evidence have suggested a number of factors associated with reduced risk of renal flares such as attaining a very low level of proteinuria (< 700-800 mg/24 h by 12 months), using mycophenolate over azathioprine, adding belimumab to standard therapy, maintaining immunosuppressive/biological treatment for at least 3 to 5 years, and using hydroxychloroquine. Other factors that warrant further clarification include serological activity and the use of repeat kidney biopsy to guide the intensity and duration of treatment in selected cases. The results from ongoing innovative studies integrating kidney histological and clinical outcomes, together with an expanding spectrum of therapies in lupus nephritis, are expected to facilitate individual medical care and long-term disease and patient prognosis.

Abstract
Objectives Glucocorticosteroids (GCs) are the most used anti-inflammatory and immunosuppressive drugs due to their effectiveness in managing pain and disease modification in many immune-inflammatory rheumatic diseases (IRDs). However, their use is limited because of adverse effects (AEs). Material and methods The authors analyzed recent studies, including randomized controlled trials (RCTs), observational, translational studies and systematic reviews, providing an in-depth viewpoint on the benefits and drawbacks of GC use in rheumatology. Results Glucocorticosteroids are essential in managing life-threatening autoimmune diseases and a cornerstone in many IRDs given their swift onset of action, necessary in flares. Several RCTs and meta-analyses have demonstrated that when administered over a long time and on a low-dose basis, GC can slow the radiographic progression in early rheumatoid arthritis (RA) patients by at least 50%, satisfying the conventional definition of a disease-modifying anti-rheumatic drug (DMARD). In the context of RA treatment, the use of modified-release prednisone formulations at night may offer the option of respecting circadian rhythms of both inflammatory response and HPA activation, thereby enabling low-dose GC administration to mitigate nocturnal inflammation and prolonged morning fatigue and joint stiffness. Long-term GC use should be individualized based on patient characteristics and minimized due to their potential AEs. Their chronic use, especially at medium/high dosages, might cause irreversible organ damage due to the burden of metabolic systemic effects and increased risk of infections. Many international guidelines recommend tapering/withdrawal of GCs in sustained remission. Treat-to-target (T2T) strategies are critical in setting targets for disease activity and reducing/discontinuing GCs once control is achieved. Conclusions Glucocorticosteroids' use in treating IRDs should be judicious, focused on minimizing use, tapering and discontinuing treatment, when possible, to improve long-term safety. Glucocorticosteroids remain part of many therapeutic regimens, particularly at low doses, and elderly RA patients, especially with associated chronic comorbidities, may benefit from long-term low-dose GC treatment. A personalized GC therapy is essential for optimal long-term outcomes.

Abstract
The KDIGO 2021 Clinical Practice Guideline for the Management of Glomerular Diseases represents the first update to this set of recommendations since the initial set of KDIGO guideline recommendations was published in 2012. The pace of growth in our molecular understanding of glomerular disease has quickened and a number of newer immunosuppressive and targeted therapies have been introduced since the original set of guideline recommendations, making such an update necessary. Despite these updates, many areas of controversy remain. In addition, further updates since the publication of KDIGO 2021 have occurred which this guideline does not encompass. With this commentary, the KDOQI work group has generated a chapter-by-chapter companion opinion article that provides commentary specific to the implementation of the KDIGO 2021 guideline in the United States.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. Its variable course makes it difficult to standardize patient treatment. This article aims at a literature review on available drugs for treating SLE and on drugs that have shown therapeutic effects in this disease. The PubMed/MEDLINE electronic search engine was used to identify relevant studies. This review presents the current therapeutic options, new biological therapies, and combination therapies of biologics with standard immunosuppressive and immunomodulating drugs. We have also underlined the importance to implement the treat-to-target strategy aimed at reducing or discontinuing therapy with glucocorticosteroids (GCs). The awareness of the benefits and risks of using GCs helps in refining their dosage and thereby obtaining a better safety profile. The advent of biological targeted therapies, and more recently, low-molecular-weight compounds such as kinase inhibitors, initiated numerous clinical trials in SLE patients and led to the approval of two biological drugs, belimumab, and anifrolumab, for SLE treatment. Progress in the treatment of SLE was reflected in the 2019 and 2021 recommendations of the European Alliance of Associations for Rheumatology (EULAR). However, a mass of recent clinical research data requires continuous consolidation to optimize patient outcomes.

Abstract
Despite the continuing development of immunomodulatory agents and supportive care, the prognosis associated with lupus nephritis (LN) has not improved substantially in the past decade, with end-stage kidney disease still developing in 5-30% of patients within 10 years of LN diagnosis. Moreover, inter-ethnic variation in the tolerance of, clinical response to and level of evidence regarding various therapeutic regimens for LN has led to variation in treatment prioritization in different international recommendations. Modalities that better preserve kidney function and reduce the toxicities of concomitant glucocorticoids are unmet needs in the development of therapeutics for LN. In addition to the conventional recommended therapies for LN, there are newly approved treatments as well as investigational drugs in the pipeline, including the newer generation calcineurin inhibitors and biologic agents. In view of the heterogeneity of LN in terms of clinical presentation and prognosis, the choice of therapies depends on a number of clinical considerations. Molecular profiling, gene-signature fingerprints and urine proteomic panels might enhance the accuracy of patient stratification for treatment personalization in the future.

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
Systemic lupus erythematosus (SLE) is a devastating autoimmune disease that can result in substantial morbidity and mortality. Diagnosis and treatment of SLE are clinical challenges. Patient presentation and response to therapy are heterogeneous because of the complex immune dysregulation that results in SLE disease pathogenesis. An intricate interplay between genetic risk and skewing of adaptive and innate immune system responses leads to overproduction of type I interferons and other cytokines, complement activation, immune-complex deposition, and ultimately inflammation and tissue damage. Here, we review the classification criteria as well as standard and emerging diagnostic tools available to identify patients with SLE. We then focus on medical management, including novel therapeutics, nonpharmacologic interventions, and comorbidity management.

Abstract
A significant number of patients with systemic lupus erythematosus (between 20% and 60% according to different reported series) develop lupus nephritis in the course of its evolution, which directly influences their quality of life and vital prognosis. In recent years, the greater knowledge about the pathogenesis of systemic lupus and lupus nephritis has allowed relevant advances in the diagnostic approach and treatment of these patients, achieving the development of drugs specifically aimed at blocking key pathogenic pathways of the disease. Encouragingly, these immunomodulatory agents have shown in well-powered, randomized clinical trials good clinical efficacy in the medium-term, defined as proteinuria remission and preservation of kidney function, with an acceptable safety profile and good patient tolerability. All this has made it possible to reduce the use of corticosteroids and other potentially more toxic therapies, as well as to increase the use of combined therapies. The present consensus document carried out by the Glomerular Diseases Working Group of the Spanish Society of Nephrology (GLOSEN), collects in a practical and summarized, but rigorous way, the best currently available evidence about the diagnosis, treatment, and follow-up of lupus nephritis patients, including cases of special situations, with the main objective of providing updated information and well-founded clinical recommendations to treating physicians, to improve the diagnostic and therapeutic approach to our patients.

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 (SLE) is a chronic multifactorial autoimmune disease that affects many organs, including the kidney. Lupus nephritis (LN) is a common manifestation characterized by heterogeneous clinical and histopathological findings, and often associates with poor prognosis. The diagnosis and treatment of LN is challenging, depending largely on renal biopsy, and there is no reliable non-invasive LN biomarker. Up to now, the complete remission rate of LN is only 20%∼30% after receiving six months of standard treatment, which is far from satisfactory. Moreover, adverse reactions to immunosuppressants, especially glucocorticoids, further compromise the prognosis of LN. Biological reagents targetting autoimmune responses and inflammatory pathways, bring hope to the treatment of intractable lupus. The European Renal Association-European Dialysis and Transplant Association (EULAR/ERA-EDTA) and KDIGO (Kidney Disease: Improving Global Outcomes) have been working on and launched the recommendations for the management of LN. In this review, we update our knowledge in the pathogenesis, diagnosis, and management of LN and prospect for the future potential targets in the management of LN.

Abstract
OBJECTIVES Our aim was to evaluate the renal response rate of patients with lupus nephritis (LN) undergoing standard treatment during a 2-year follow-up and to investigate its predictive factors. METHODS A prospective cohort study that enrolled 56 clinically diagnosed LN patients with urinary protein positivity was carried out. All patients underwent standard treatment. All patients were followed up at 6-month intervals for 2 years. Data on renal response and clinical characteristics were collected and analyzed. RESULTS Among 56 patients, 27 (48.2%) and 13 (23.2%) patients achieved complete renal response (CR) and partial renal response (PR) at 6 months after induction therapy, respectively, and 42 (75.0%) and 4 (7.1%) patients developed CR and PR at 2 years. Among patients who achieved PR at 6 months, 90.0% achieved CR at 24 months, while only 37.5% of the patients who were unresponsive at 6 months achieved CR. In the multivariable Cox proportional-hazards model, female (OR 6.51, 95% CI 1.23-34.52, p = 0.028), disease duration (OR 0.84, 95% CI 0.73-0.98, p = 0.021), achieving PR within 6 months (OR 8.09, 95% CI 2.06-31.73, p = 0.003), and urine protein/creatinine ratio (UPCR) (OR 0.998, 95% CI 0.996-1.000, p = 0.025) were found to be predictive factors of CR. CONCLUSION A total of 48.2% of patients achieved CR at 6 months of induction therapy, and the response rates gradually increased to 60.7%, 64.3%, and 75.0% at 12, 18, and 24 months. Besides, female, disease duration, partial response within 6 months, and UPCR were predictive factors for a complete renal response. Key Points • We evaluate the renal response rates in Chinese patients with lupus nephritis in the real world for 2 years. • A total of 48.2% and 75.0% of patients achieved a complete response after standard treatment for 6 months and 2 years. • Female, disease duration, partial response within 6 months, and UPCR are predictors of complete renal response.

Abstract
Objective To systematically evaluate the effects of peritoneal dialysis and hemodialysis on renal function and quality of life in patients with end-stage renal disease. An evidence-based medical rationale would be provided for peritoneal dialysis or hemodialysis treatment in patients with end-stage renal disease. Methods The PubMed, EMBASE, ScienceDirect, Cochrane Library, China National Knowledge Infrastructure (CNKI), China VIP Database, Wanfang, and China Biomedical Literature Database (CBM) online databases were searched. Comparisons on the effects of peritoneal dialysis on renal function and quality of life were taken between patients with end-stage renal disease (RD). The data were extracted independently by two researchers. The bias-risk-included literatures were assessed according to the Cochrane manual 5.1.0 standard. RevMan 5.4 statistical software was used to analyze the collected data via meta-analysis. Results Seven RCT articles were finally included. A total of 745 samples were analyzed via meta-analysis. The obvious heterogeneities of serum creatinine (Scr) and blood urea nitrogen (BUN) were discovered (P < 0.00001) in the selective investigations. According to the results of this analysis, it was indicated that the renal function of patients with end-stage renal disease treated by peritoneal dialysis was significantly better than that of hemodialysis. According to the meta-analysis, there was obvious heterogeneity of life quality among the included research data. It was indicated that the score of quality of life of patients with end-stage renal disease treated by peritoneal dialysis was significantly better than that of hemodialysis. Conclusion Compared with hemodialysis in the treatment of end-stage renal disease, the renal function and quality of life of patients with peritoneal dialysis are better than those of hemodialysis. More further studies and follow-up with higher methodological quality and longer intervention time are still needed for further verification.

Abstract
Despite improvements in patient and renal death rates following the introduction of potent immunosuppressive drugs in earlier decades, a sizeable fraction of patients with lupus nephritis is burdened with suboptimal or delayed responses, relapses, chronic use of glucocorticoids and accrual of renal (chronic renal insufficiency) and extra-renal organ damage. The recently approved combinatory treatments comprising belimumab or voclosporin added to conventional agents, especially mycophenolate, hold promise for further improving disease outcomes and enabling a faster steroid tapering, thus being relevant to the treat-to-target context. However, it remains uncertain whether these dual regimens should become the first-line choice for all patients or instead be prioritized to certain subgroups. In the present article, we summarize the existing lupus nephritis management recommendations, followed by a critical appraisal of the randomized trials of belimumab and voclosporin, as well as the available data on obinutuzumab and other novel compounds under development. We conclude that pending the identification of accurate clinical, histological, or translational predictors for guiding personalized decisions, it is of utmost importance that lupus nephritis patients are monitored closely with appropriate treatment adjustments aiming at a prompt, deep response to ensure long-term preservation of kidney function.

Abstract
The observations that traditional cardiovascular disease (CVD) risk factors fail to fully account for the excessive cardiovascular mortality in patients with systemic lupus erythematosus (SLE) compared with the general population have prompted in-depth investigations of non-traditional, SLE-related risk factors that contribute to cardiovascular complications in patients with SLE. Of the various perturbations of vascular physiology, endothelial dysfunction, which is believed to occur in the earliest step of atherosclerosis, has been extensively investigated for its contribution to CVD risk in SLE. Endothelial progenitor cells (EPCs), which play a crucial part in vascular repair, neovascularization and maintenance of endothelial function, are quantitatively and functionally reduced in patients with SLE. Yet, the lack of a unified definition of EPCs, standardization of the quantity and functional assessment of EPCs as well as endothelial function measurement pose challenges to the translation of endothelial function measurements and EPC levels into prognostic markers for CVD in patients with SLE. This Review discusses factors that contribute to CVD in SLE, with particular focus on how endothelial function and EPCs are evaluated currently, and how EPCs are quantitatively and functionally altered in patients with SLE. Potential strategies for the use of endothelial function measurements and EPC quantification as prognostic markers of CVD in patients with SLE, and the limitations of their prognostication potential, are also discussed.

T Cells, Interleukin-2 and Systemic Lupus Erythematosus—From Pathophysiology to Therapy. Cells 2022; 11:cells11060980.

Abstract
The phenotypic and functional complexities of T cells engender complicated and often confusing concepts as to how T cells ignite, accelerate and brake the inflammatory processes involved in systemic lupus erythematosus (SLE), let alone the plasticity of T cells that takes place under different immunological contexts. Nevertheless, being one of the prime survival factors of T cells, interleukin (IL)-2 plays a potentially critical role in many immunological scenarios during the pathophysiological process of SLE. Here, the pathophysiology of lupus T cells and current, as well as ongoing, therapeutic approaches of SLE that involve low-dose IL-2 administration will be highlighted. The mechanisms of IL-2 deficiency in SLE pathophysiology, the effects of low-dose IL-2 on T cells and restoration of lupus manifestations in murine SLE models, as well as the efficacy and safety of clinical trials that evaluated low-dose IL-2-containing regimens in patients with SLE will be discussed.

Abstract
P-glycoprotein (P-gp)-mediated efflux of corticosteroids (CS) may contribute to treatment unresponsiveness in Lupus Nephritis (LN) patients. Tacrolimus is a P-gp inhibitor and hence, may overcome this resistance. We aimed to study the response to tacrolimus, along with the expression and function of P-gp on peripheral blood lymphocytes (PBL) in patients with refractory and relapsing proliferative Lupus Nephritis. We enrolled 12 refractory/relapsing LN patients and treated them with corticosteroids and tacrolimus for 6 months. Expression and function of P-gp on PBL was measured by flow cytometry (as relative fluorescence index, RFI and Rhodamine dye efflux assay) before and 3 months after tacrolimus therapy. Renal response was assessed according to ACR response criteria after 3 and 6 months of tacrolimus therapy. 8 out of 12 refractory/relapsing LN patients achieved renal response (5 partial response, PR and 3 complete responses, CR) as early as 3 months, and 11 patients achieved renal response (7 PR and 4 CR) at 6 months from start of tacrolimus therapy. Proteinuria decreased from median urine protein creatinine ratio (UPCR) of 2.80 (2.00-3.40) at baseline to 1.20 (0.66-1.73) at 3 months (p < 0.001) and to 0.80 (0.19-1.30) at 6 months (p < 0.01). There was significant decrease in P-gp expression [RFI, 3.33 (2.87-4.97) vs 2.03 (1.25-3.86), p < 0.05) and P-gp function (RFI, 55.7 (29.7-84.1) vs 26.8 (16.1-37.0), p < 0.01) after 3 months of tacrolimus therapy. Tacrolimus achieves renal response in refractory/relapsing proliferative LN patients which may be partly related to overcoming P-glycoprotein mediated treatment unresponsiveness.

Abstract
Calcineurin inhibitors (CNIs) are drugs that inhibit calcineurin, a key phosphatase that dephosphorylates a transcription factor called the nuclear factor of activated T cells (NFAT), allowing its translocation into the nucleus of quiescent T cells. In the nucleus, NFAT activates interleukin 2, which stimulates the proliferation and differentiation of T-cells. CNIs can also stabilize the actin cytoskeleton of podocytes reducing proteinuria. Thanks to these characteristics, CNIs have been often used in the treatment of autoimmune diseases. However, the therapeutic index of CNIs is narrow, and their interactions with other drugs can increase toxicity or reduce efficacy. In lupus nephritis, cyclosporine and tacrolimus have been used both in induction and maintenance therapies. Observational studies and randomized controlled trials showed that both cyclosporine and tacrolimus can increase efficacy. Tolerance is satisfactory if low doses are used and the patient is carefully monitored. More recently, a new CNI, called voclosporin (VCS), has been approved by the Food and Drug Administration for use in lupus nephritis. VCS offers potential advantages over other CNIs. In two large multiethnic trials, VCS was not associated with adverse renal and metabolic events and obtained positive results despite a novel and rapid corticosteroid tapering regime.

Abstract
INTRODUCTION Kidney survival rates in lupus nephritis (LN) remain suboptimal, with 10-20% of patients progressing to end-stage kidney disease by 10-20 years. Recently, the landscape of LN management has changed with the advent of new molecules that have demonstrated safety and efficacy in clinical trials. AREAS COVERED In this review, we approach the current state of LN management, the unmet therapeutic needs, and deep dive into voclosporin, a novel calcineurin inhibitor (CNI) that has demonstrated improved efficacy when added to a mycophenolate mofetil (MMF) and glucocorticoid regimen, without an increase in adverse events. We focus on the characteristics of this new CNI and the studies that led to its approval by the US FDA. EXPERT OPINION Voclosporin adds to therapeutic options for LN. This drug offers potential advantages over other CNIs. The addition of voclosporin to a standard-of-care regimen of MMF/glucocorticoids demonstrated higher and faster response rates. As other regimens, a combination of CNI, MMF, and glucocorticoids must be individualized and is not appropriate for all patients. Some questions remain to be answered for this regimen, such as the length of treatment, the tapering schedule, and its long-term safety and efficacy for preserving kidney function.

Abstract
PURPOSE OF REVIEW Because of the complexity of systemic lupus erythematosus (SLE), different approaches are undertaken while investigating potential therapeutic compounds to treat the disease. The purpose of this review is to summarize the results from recent clinical trials, which investigated different compounds for treating SLE. RECENT FINDINGS Targeting B cells and type I interferons constitutes the major focus in recent clinical trials. The potential for therapeutic effects of small molecule inhibition such as JAK, Tyk, and Btk is now being investigated for treating SLE. The immunoregulation of T cell activation in SLE is studied using low-dose IL-2 and CD40 ligand inhibition. There are clinical trials that study bispecific antibodies, with binding specificities for 2 different target molecules related to T- and B-cell activation or to different aspects of B cell activation. An approach of combination treatment is also being studied. Clinical trials are underway and new treatment compounds for SLE are being anticipated.

The Asia-Pacific League of Associations for Rheumatology consensus statements on the management of systemic lupus erythematosus. THE LANCET. RHEUMATOLOGY 2021; 3:e517-e531.

Abstract
Systemic lupus erythematosus (SLE) is prevalent in Asia and carries a variable prognosis among patients across the Asia-Pacific region, which could relate to access to health care, tolerability of medications, and adherence to therapies. Because many aspects of SLE are unique among patients from this region, the Asia-Pacific League of Associations for Rheumatology developed the first set of consensus recommendations on the management of SLE. A core panel of 13 rheumatologists drafted a set of statements through face-to-face meeting and teleconferences. A literature review was done for each statement to grade the quality of evidence and strength of recommendation. 29 independent specialists and three patients with SLE were then recruited for a modified Delphi process to establish consensus on the statements through an online voting platform. A total of 34 consensus recommendations were developed. Panellists agreed that patients with SLE should be referred to a specialist for the formulation of a treatment plan through shared decision making between patients and physicians. Remission was agreed to be the goal of therapy, but when it cannot be achieved, a low disease activity state should be aimed for. Patients should be screened for renal disease, and hydroxychloroquine is recommended for all Asian people with SLE. Major organ manifestations of SLE should be treated with induction immunosuppression and subsequently maintenance; options include cyclophosphamide, mycophenolate mofetil, azathioprine, and calcineurin inhibitors, in combination with glucocorticoids. Biologics, combination regimens, plasma exchange, and intravenous immunoglobulins should be reserved for cases of refractory or life-threatening disease. Anticoagulation therapy with warfarin is preferred to the direct oral anticoagulants for thromboembolic SLE manifestations associated with a high-risk antiphospholipid antibody profile.

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

Abstract
Despite progress in the treatment of systemic lupus erythematosus (SLE), remission rates and health-related quality of life remain disappointingly low. The paucity of successful SLE clinical trials reminds us that we still have a long way to go. Nevertheless, there are clear signs of hope. We highlight results from recent studies of novel therapeutic strategies based on emerging insights into our understanding of SLE disease mechanisms. We also highlight several studies that inform optimal use of existing treatments to improve efficacy and/or limit toxicity. These developments suggest we may yet unlock the key toward more satisfactory treatment outcomes in SLE.

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
Systemic lupus erythematosus (SLE) is a complicated multisystem autoimmune disease that is associated with significant mortality and morbidity in the younger population. The development of novel therapies of SLE lag behinds other autoimmune inflammatory rheumatic diseases because of its clinical and immunological heterogeneities, the complexity of outcome assessments in multiple systems, and difficulty in optimizing the design of clinical trials. Despite the futility of quite a number of clinical trials, we are seeing the dawn of novel therapeutics in SLE, given the promising results of the newer-generation anti-CD20, anti-CD40L biologics, and calcineurin inhibitors (CNIs), as well as anti-cytokine biologics, Jakinibs, and the mammalian target of rapamycin (mTOR) inhibitors. The initial success of the Jakinibs and combination regimens in SLE illustrates the importance of targeting multiple pathogenetic mechanisms. The results of the ongoing phase III clinical trials in SLE are eagerly awaited.
