Liu S, Li J, Zhang Z, Meng D, Wang K. Serum IFN-γ Predicts the Therapeutic Effect of Belimumab in Refractory Lupus Nephritis Patients. Pharmgenomics Pers Med 2024; 17:443-452. [PMID: 39376665 PMCID: PMC11457469 DOI: 10.2147/pgpm.s476308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Accepted: 09/24/2024] [Indexed: 10/09/2024] Open
Abstract
Objective To evaluate belimumabf's efficacy in refractory lupus nephritis (LN) patients and identify predictive serum biomarkers for treatment response. Methods In this single-arm retrospective study, we assessed clinical responses in LN patients at baseline and six months after initiating belimumab. Serum cytokines (IL-2, IL-4, IL-6, IL-10, TNF-α, IFN-γ) were quantified using multiplex magnetic bead flow immunoassay before and after treatment. Results Fourteen patients with various subtypes of refractory LN participated in the study: seven with class III and V LN, three with type V alone, two with class III, and two with class IV+V and V LN. Post six months of belimumab therapy, all participants exhibited a reduction in the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K scores from their respective baseline values. Notably, most patients showed a decrease in the dosage of prednisone, levels of 24-hour urinary protein, immunoglobulins, erythrocyte sedimentation rate (ESR), and anti-double-stranded DNA antibody IgM, along with serum levels of IL-4, IL-6, IL-10, and IFN-γ. Meanwhile, levels of C3, C4, IL-2, and TNF-α were observed to increase. Of the participants, nine (64.29%) achieved a complete renal response, one (7.14%) showed a partial response, and four (28.57%) exhibited no response. Significantly, higher baseline serum IFN-γ levels were found in patients who did not achieve complete renal response (CR) compared to those who did (p = 0.009). Receiver operating characteristic (ROC) curve analysis demonstrated that baseline IFN-γ levels had an area under curve (AUC) of 0.96 (0.70-1.00), with a sensitivity of 0.89 and a specificity of 1.00 (p < 0.001). Conclusion Belimumab shows potential efficacy in treating refractory LN. Baseline serum IFN-γ levels may predict response to belimumab therapy, potentially enabling more targeted treatment approaches for this challenging condition.

Abstract
Systemic lupus erythematosus (SLE), antiphospholipid syndrome (APS), and Sjögren's syndrome (SS) are heterogeneous autoimmune diseases. Severe manifestations and refractory/intolerance to conventional immunosuppressants demand other options, namely biological drugs, and small molecules. We aimed to define evidence and practice-based guidance for the off-label use of biologics in SLE, APS, and SS. Recommendations were made by an independent expert panel, following a comprehensive literature review and two consensus rounds. The panel included 17 internal medicine experts with recognized practice in autoimmune disease management. The literature review was systematic from 2014 until 2019 and later updated by cross-reference checking and experts' input until 2021. Preliminary recommendations were drafted by working groups for each disease. A revision meeting with all experts anticipated the consensus meeting held in June 2021. All experts voted (agree, disagree, neither agree nor disagree) during two rounds, and recommendations with at least 75% agreement were approved. A total of 32 final recommendations (20 for SLE treatment, 5 for APS, and 7 for SS) were approved by the experts. These recommendations consider organ involvement, manifestations, severity, and response to previous treatments. In these three autoimmune diseases, most recommendations refer to rituximab, which aligns with the higher number of studies and clinical experience with this biological agent. Belimumab sequential treatment after rituximab may also be used in severe cases of SLE and SS. Second-line therapy with baricitinib, bortezomib, eculizumab, secukinumab, or tocilizumab can be considered in SLE-specific manifestations. These evidence and practice-based recommendations may support treatment decision and, ultimately, improve the outcome of patients living with SLE, APS, or SS.

Mod Rheumatol Case Rep 2023; 7:78-81.

Abstract
Rituximab is indicated in some patients with refractory systemic lupus erythematosus (SLE). Occasionally, this medication is required in chronic form to maintain control of the disease. We described two patients who developed lymphoid follicular hyperplasia (LFH) after multiple cycles of rituximab and evaluated the expression of B cell activating factor belonging to the tumor necrosis factor (TNF) family (BAFF) and its receptors [BAFF-receptor (BAFF-R) and B cell maturation antigen (BCMA)], as possible factors related to lymphoid node enlargement. Two patients with SLE completed six and nine cycles of rituximab (1 g every 2 weeks) indicated each 9 months, achieving remission for 5 and 7 years, respectively, when developed prominent lymphadenopathies. Biopsies showed LFH. Haematological neoplasms were ruled out. Immunohistochemistry showed BAFF overexpression in the follicles, and moderate expression of BAFF-R confined to the mantle zone and BCMA to the germinal centre. Belimumab B cell activating factor belonging to the TNF family (anti-BAFF therapy) was started with positive effects on the clinical condition. LFH can develop in patients with SLE who received multiple cycles of rituximab. BAFF overexpression and moderate expression of BAFF-R and BCMA in lymph nodes were seen. These findings added to the improvement with the change to belimumab could suggest that LFH after cluster of differentiation (CD20) depletion therapy may be associated with a compensatory overexpression of BAFF and its receptors.

Abstract
In recent years, advances in the treatment and management of patients with systemic lupus erythematosus (SLE) have improved their life expectancy and quality of life. However, lupus nephritis (LN) still represents a major life-threatening complication of the disease. Belimumab (BEL), a fully human monoclonal IgG1λ antibody neutralizing soluble B cell activating factor, was approved more than ten years ago as add-on therapy in adults and pediatric patients with a highly active, autoantibody-positive disease despite standard of care (SoC). Recently, the superiority of the addition of BEL to SoC was also demonstrated in LN. In this review, we provide a comprehensive overview of the study landscape, available therapeutic options for SLE (focusing on BEL in renal and non-renal SLE), and new perspectives in the treatment field of this disease. A personalized treatment approach will likely become available with the advent of novel therapeutic agents for SLE and LN.

Abstract
AIM To study the expression of B cell-activating factor of tumor necrosis factor family (BAFF) and A proliferation-inducing ligand (APRIL) genes in active and remitting patients with anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) and healthy controls and their correlation with disease activity. METHODS This was a prospective case-control study. Gene expressions of BAFF and APRIL were studied in 32 patients with AAV (16 each with active disease and in remission) and 30 healthy age and sex matched controls by real-time polymerase chain reaction. RESULTS Out of 32 AAV patients, 26 had granulomatosis with polyangiitis (GPA) and 6 had microscopic polyangiitis (MPA). Mean ages of patients in active (12 GPA and 4 MPA) and remission (14 GPA and 2 MPA) groups were 39.4 ± 17.2 and 44.6 ± 16.1 years, respectively. BAFF gene expression was significantly higher in both the active AAV group and remission AAV group compared to controls (P < .01). The BAFF expression was significantly higher in AAV patients in remission compared to active AAV patients (P = .003). In contrast, APRIL expression did not differ between AAV patients and controls (P = .829). However, APRIL had significantly higher expression in remission as compared to active patients (P = .048). There was no significant correlation of both BAFF and APRIL expression with disease activity markers (erythrocyte sedimentation rate, C-reactive protein, platelets and Birmingham Vasculitis Activity Score version 3). CONCLUSION BAFF gene is significantly expressed in patients with AAV. Among AAV patients, there is a significantly higher expression of BAFF and APRIL in remitting state of the disease as compared to active state. There is no significant change in APRIL gene expression in patients with AAV as compared to controls. This makes a case for anti-BAFF therapy in future for AAV patients in northern India.

Abstract
Systemic lupus erythematosus (SLE) and bullous pemphigoid (BP) are chronic autoimmune diseases in which B cells play an important pathogenic role in the different stages of the disease. B cell-targeted therapies have been suggested as a new rational approach for treating SLE. Rituximab (RTX), an anti-CD20 chimeric monoclonal antibody, failed to achieve primary endpoints in two clinical trials (EXPLORER and LUNAR) despite multiple observational and retrospective studies showing its beneficial effect on SLE. Moreover, RTX is recommended in cases of BP that is unresponsive to conventional treatments. Belimumab (BLM), a human immunoglobulin G1 λ monoclonal antibody that inhibits soluble B-lymphocyte stimulator (BlyS)/B-cell activating factor (BAFF), is the only biological treatment approved for standard therapy of refractory autoantibody-positive active SLE. Animal models and a few case reports have supported the efficacy of the combined use of RTX followed by BLM as maintenance therapy in severe lupus nephritis (LN), suggesting that their combined use may be more effective than their single use, without compromising safety. In this study, we describe the clinical case of a SLE patient with predominant renal involvement in overlap with BP, refractory to conventional therapy including RTX alone, achieving significant steroid sparing and clinical remission under sequential treatment of RTX-BLM. Moreover, we describe the first case of BP successfully treated with BLM. This case report may encourage further clinical research studies in B lymphocyte targeted combination therapy in patients affected by SLE with major organ involvement or with refractory disease, suggesting that RTX and BLM sequential therapy may be a valid option for the treatment of SLE manifestations, including conventional therapy and RTX-resistant LN.

Abstract
Background: Systemic lupus erythematosus (SLE) is an autoimmune condition with a wide spectrum of clinical manifestations encompassing most organs and systems. Its treatment approach includes different immunomodulatory treatments, of which B-cell targeted therapies are part of. Rituximab (an anti-CD20 antibody) had encouraging results in observational studies but failed when tested in clinical trials. It is theorized that this could have been partially due to BAFF upregulation, leading to rituximab failure. Therefore, targeting BAFF with belimumab after rituximab therapy, may have a synergic effect in SLE. Objective: We review the available observational data regarding sequential rituximab/belimumab therapy in SLE patients. Results: Twenty-four patients from 6 studies were included. The results suggest a benefit with this combined therapy, with reduction of the mean SLEDAI. However, there was significant drug regimen and patient selection heterogeneity. Conclusion: Further randomized clinical trials are needed to examine this drug sequencing protocol in SLE patients.

Abstract
Background Anti-CD20 B-cell depletion has not shown superior efficacy to standard immunosuppression in patients with systemic lupus erythematosus (SLE). Besides trial design, potential explanations are incomplete B-cell depletion in relation to substantial surges in B-cell-activating factor (BAFF). To improve B-cell targeting strategies, we conducted the first study in SLE patients aimed at investigating immunological effects and feasibility of combining rituximab (RTX; anti-CD20) and belimumab (BLM; anti-BAFF). Methods Reported is the long-term follow-up of a Phase 2 proof-of-concept study in 15 patients with SLE including 12 (80%) with lupus nephritis (LN). Results In 10/15 (67%) patients, a clinical response was observed by achievement of lupus low disease activity state, of which 8 (53%) continued treatment (BLM + ≤7.5 mg prednisolone) for the complete 2 years of follow-up. Five patients (33%) were referred to as ‘non-responders’ due to persistent LN, major flare or repetitive minor flares. Out of 12 LN patients, 9 (75%) showed a renal response including 8 (67%) complete renal responders. All anti-dsDNA+ patients converted to negative, and both anti-C1q and extractable nuclear antigen autoantibodies showed significant reductions. CD19+ B cells showed a median decrease from baseline of 97% at 24 weeks, with a persistent reduction of 84% up to 104 weeks. When comparing responders with non-responders, CD20+ B cells were depleted significantly less in non-responders and double-negative (DN) B cells repopulated significantly earlier. Conclusions Combined B-cell targeted therapy with RTX and BLM prevented full B-cell repopulation including DN B cells, with concomitant specific reduction of SLE-relevant autoantibodies. The observed immunological and clinical benefits in a therapy-refractory SLE population prompt further studies on RTX + BLM.

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
Objective To evaluate the safety and efficacy of belimumab as adjunctive therapy to maintain remission in antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV). Methods In this multicenter, double‐blind, placebo‐controlled study, patients with AAV (ages ≥18 years) were randomized 1:1 to receive azathioprine (2 mg/kg/day), low‐dose oral glucocorticoids (≤10 mg/day), and either intravenous belimumab (10 mg/kg) or placebo, following remission induction with rituximab or cyclophosphamide along with glucocorticoids. The primary end point was time to first protocol‐specified event (PSE), with first PSE defined as a Birmingham Vasculitis Activity Score (BVAS) of ≥6, presence of ≥1 major BVAS item, or receipt of prohibited medications for any reason, resulting in treatment failure (adjusted for ANCA type [proteinase 3 (PR3) or myeloperoxidase (MPO)], disease stage at induction, and induction regimen). Vasculitis relapse was defined as the PSE of either a BVAS activity score of ≥6 or receipt of prohibited medications for vasculitis. Changes in treatment practice led to truncation of the study population from ~300 patients to ~100 patients. Results The intent‐to‐treat population totaled 105 patients with AAV, of whom 52 (40 with PR3‐ANCAs, 12 with MPO‐ANCAs) received placebo and 53 (41 with PR3‐ANCAs, 12 with MPO‐ANCAs) received belimumab; 27 of the patients were in rituximab‐induced disease remission, while 78 were in cyclophosphamide‐induced disease remission at baseline. Compared with placebo, treatment with belimumab did not reduce the risk of a PSE (adjusted hazard ratio [HR] 1.07, 95% confidence interval [95% CI] 0.44–2.59; P = 0.884) or vasculitis relapse (adjusted HR 0.88, 95% CI 0.29–2.65; P = 0.821). The overall rate of PSEs was low (11 [21.2%] of 52 patients receiving placebo, 10 [18.9%] of 53 patients receiving belimumab). Vasculitis relapse in the placebo group (n = 8) occurred independent of the induction regimen, disease stage, or ANCA type. All vasculitis relapses in the belimumab group (n = 6) occurred in patients who had PR3‐ANCA–associated vasculitis with cyclophosphamide‐induced disease remission. Adverse events occurred in 49 (92.5%) of 53 patients receiving belimumab and 43 (82.7%) of 52 patients receiving placebo, with no new safety concerns. Conclusion Belimumab plus azathioprine and glucocorticoids for the maintenance of remission in AAV did not reduce the risk of relapse.

Abstract
Immunoglobulin (Ig)G4-related disease (IgG4-RD) is an unusual complication of systemic lupus erythematosus (SLE). We report a case in which belimumab proved efficacious for not only SLE, but also IgG4-RD. A 58-year-old Japanese woman had suffered from photodermatosis and erythema on the limbs for 20 years. She presented in slight fever and fatigue since 2016. Laboratory data showed hypergammaglobulinemia, proteinuria and positive results for anti-nuclear antibody and anti-double-stranded DNA antibody. Furthermore, elevated levels of serum IgG4 were detected. Contrast-enhanced computed tomography disclosed multiple areas of poor enhancement in the kidneys. The patient was diagnosed with lupus nephritis and IgG4-RD from renal biopsy. Treatment was started with prednisolone at 40 mg/day and mycophenolate mofetil. Proteinuria and serological findings improved initially, but tapering the dose of glucocorticoid proved difficult. After treatment was started with belimumab, clinical symptoms and proteinuria resolved completely. The dose of glucocorticoid was successfully tapered and serum concentration of IgG4 fell further. This appears to represent the first report of a case in which both SLE and IgG4-RD were effectively treated using belimumab.

Abstract
INTRODUCTION Belimumab, an anti-B-lymphocyte-stimulator antibody, is approved for the treatment of active, autoantibody-positive systemic lupus erythematosus (SLE). Rituximab, a B cell-depleting anti-CD20 antibody, remains in the SLE treatment armamentarium despite failed trials in lupus nephritis and extrarenal lupus. These biologics, which operate through complementary mechanisms, might result in an enhanced depletion of circulating and tissue-resident autoreactive B lymphocytes when administered together. Thus, belimumab and rituximab combination may be a highly effective treatment of SLE. This study aims to evaluate and compare the efficacy, safety and tolerability of subcutaneous (SC) belimumab and a single cycle of rituximab in patients with SLE with belimumab alone. METHODS AND ANALYSIS BLISS-BELIEVE is a three-arm, randomised, double-blind, placebo-controlled, 104-week superiority study. Two hundred adults with SLE will be randomised 1:2:1 to arm A, belimumab SC 200 mg/week for 52 weeks plus placebo at weeks 4 and 6; arm B, belimumab SC 200 mg/week for 52 weeks plus rituximab 1000 mg at weeks 4 and 6; arm C, belimumab SC 200 mg/week plus standard of care for 104 weeks. The 52-week treatment period (arms A and B) is followed by a 52-week observational phase. The primary efficacy endpoint is the proportion of patients with disease control (SLE Disease Activity Index (SLEDAI)-2K≤2, without immunosuppressants and with a prednisone-equivalent dose of ≤5 mg/day) at week 52. Major secondary efficacy endpoints are the proportion of patients in clinical remission (defined as SLEDAI-2K=0, without immunosuppressants and corticosteroids) at week 64, and the proportion of patients with disease control at week 104. Safety endpoints include the incidence of adverse events (AEs), serious AEs and AEs of special interest. ETHICS AND DISSEMINATION Within 6 months of the study's primary manuscript publication, anonymised individual participant data and study documents can be requested for further research from www.clinicalstudydatarequest.com.

Abstract
Purpose of Review: The standard treatment options for systemic lupus erythematosus (SLE) are focused on non-specific immunosuppression. Over the past few years, scientific studies and ongoing clinical trials have shifted the paradigm with rapid advances in developing biologics and small molecules. A number of monoclonal antibodies and small molecule inhibitors have been developed to target specific pathways involved in SLE. Many of these novel therapeutic agents are already being tested in clinical trials and they may 1 day reshape the landscape of SLE treatment. Herein we review potential future therapeutic options for SLE.

Efficacy of Belimumab for active lupus nephritis in a young Hispanic woman intolerant to standard treatment: a case report. BMC Nephrol 2018; 19:276.

Abstract
Background Lupus nephritis (LN) is a frequent severe complication of Systemic Lupus Erythematosus (SLE), especially in patients of non-Caucasian ethnicity. Induction treatment for LN consists in the combination of steroids plus a second agent (cyclophosphamide or mycophenolate mofetil) or, as a second-line, calcineurin inhibitors or Rituximab. Induction treatment for LN can be complicated by a series of side effects, the most severe being serious infections. Belimumab is a fully humanized monoclonal antibody that targets soluble B lymphocyte stimulator (BLyS), approved for treatment of serologically active SLE in addition to standard of care. Case presentation A young Hispanic woman was diagnosed with SLE at the age of 15. After several immunosuppressive treatments for arthritic symptoms (high-dose steroids, mycophenolate mofetil, Rituximab, cyclophosphamide) leading to serious complications and scarce clinical improvement, she developed severe LN. Induction treatment with a combination of intravenous high-dose methylprednisolone and cyclophosphamide was started but, after few days, the patient developed cryptococcal meningitis. After institution of appropriate antifungal therapy, treatment with Tacrolimus was attempted but poorly tolerated by the patient and withdrawn. Eventually, Belimumab was initiated off-label as a last resource to treat LN. Belimumab was well tolerated by the patient and resulted in a rapid and marked improvement in clinical symptoms and reduction in proteinuria, serum complement levels and anti-dsDNA titer; of note, the patient developed no infectious complications. Conclusions We report the case of a severe LN in a young Hispanic woman who did not respond to conventional and second-line induction therapies, due both to intolerance and to the development of serious infectious complications. Eventually, Belimumab was successfully added to steroids and was well tolerated by the patient, resulting in a marked improvement in clinical and biochemical parameters. We suggest that Belimumab should be considered as a potentially efficacious treatment in patients with LN who cannot tolerate conventional therapies.

Abstract
Objective: to investigate the effect of various biological agents (BAs), including combined treatment with rituximab (RTM) and belimumab (BLM), on the activity of systemic lupus erythematosus (SLE) and to evaluate their efficacy and impact on some parameters of humoral immunity.Subjects and methods. BAs were prescribed to 54 patients with a reliable diagnosis of SLE with high and medium activity according to SLEDAI-2K; 40 of them received RTM, 7 – BLM; 7 – combined therapy with RTM and BLM. Clinical and laboratory examinations were made in all the patients at the time of their inclusion and then every 3 months during a year. The results were assessed using SLEDAI-2K, BILAG index, Lupus Erythematosus National Assessment (SELENA)-SLEDAI Flare index (SFI) (a moderate, severe exacerbation), and SLE Responder Index (SRI).Results and discussion. At 3, 6, and 12 months after start of therapy, the use of BAs in all the patients resulted in a disease activity reduction. It was statistically significant (p < 0.00001) in the RTM group; and no statistical analysis was carried out in the BLM and RTM+BLM groups due to the small numbers of patients. At the same time, there was a progressive decrease in the levels of anti-double-stranded DNA (ds-DNA) antibodies (Abs) and an increase in the concentration of the complement fractions C3 and C4 in the RTM and RTM+BLM groups (p < 0.05) at one-year follow-up. After 12 months of therapy with BAs, there was a decrease in IgG (p < 0.02) and IgM (p < 0.03) levels; but overall it remained within the reference ranges. Prior to therapy, irreversible organ damages were recorded in 23 (42.6%) of the 54 patients. The increased damage index at 12 month was observed only in patients receiving RTM, which is probably due to the use of higher-dose glucocorticoids.Conclusion. All three methods of therapy with BAs in SLE patients demonstrated good efficiency shown as a significant decrease in clinical and laboratory activity measures that were assessed by SLEDAI-2K and the levels of anti-ds-DNA and complement components C3 and C4. The decrease in immunoglobulin levels did not go beyond the reference values. Therapy with BLM and RTM+BLM allowed for managing patients with the low and average doses of oral glucocorticoids, which contributed to the reduction of not only the activity, but also risk of irreversible organ damages.

Abstract
OBJECTIVE In systemic lupus erythematosus (SLE) patients, excessive formation of neutrophil extracellular traps (NETs) is observed and their degradation is impaired. In vitro, immune complexes (ICx) trigger NET formation while NET-derived DNA is a postulated autoantigen for anti-nuclear autoantibodies (ANAs), found in SLE. Based on these self-perpetuating mechanisms in SLE, this study investigates whether interfering with ICx formation using a combination of rituximab (RTX) and belimumab (BLM) could decrease NET formation and ameliorate disease. METHODS A phase 2A, open-label, single arm proof-of-concept study was performed wherein 16 SLE patients with severe, refractory disease were treated with a combination of CD20-mediated B-cell depletion with rituximab and sustained inhibition of B-cell activating factor BlyS with belimumab. Besides safety, the study's endpoints were chosen to address the concept of autoantibodies in relation to excessive NET formation. RESULTS We demonstrated a surge of BlyS levels upon RTX-mediated B-cell depletion which was abrogated by subsequent BLM treatment. As such, therapeutic intervention with RTX + BLM led to specific reductions in ANAs and regression of excessive NET formation. RTX + BLM appeared to be safe and achieved clinically significant responses: low lupus disease activity state was achieved in 10 patients, renal responses in 11 patients and concomitant immunosuppressive medication was tapered in 14 out of the 16 patients. CONCLUSIONS This study provides novel insights into clinical beneficence of reducing excessive NET formation in SLE by therapeutic targeting ANA production with RTX + BLM. Altogether putting forward a new treatment concept that specifically ameliorates underlying SLE pathophysiology. TRIAL REGISTRATION ClinicalTrials.gov NCT02284984.

Abstract
Background The treatment of Lupus Nephritis (LN) is an unmet need in the management of patients with Systemic Lupus Erythematosus (SLE). Case presentation We report two cases of women affected by Lupus Nephritis (LN) ISN/RNP Class IV with serological active disease, high disease activity and marked fatigue. In both cases, Mycophenolate mofetil (MMF), as induction therapy, was poorly tolerated because of gastrointestinal toxicity. Belimumab, together with low-doses of MMF, was effective as induction treatment leading to early achievement of complete renal response in these two selected cases of LN. Conclusions We also report a literature review concerning the efficacy and safety of Belimumab in Lupus Nephritis. Further studies are needed to evaluate the use of Belimumab to manage the renal involvement in patients with Systemic Lupus Erythematosus, waiting for the results of ongoing randomized clinical trials.

Abstract
BACKGROUND Low disease activity is a validated target of current systemic lupus erythematosus (SLE) therapy. The aim of this study was to assess the ability of belimumab to achieve low disease activity states in real-life settings. METHODS Multicentre prospective observational study of consecutive SLE patients receiving belimumab for at least 3 months, due to active disease refractory to at least one conventional immunosuppressant. Disease activity, including the recently defined lupus low disease activity state (LLDAS) and remission (clinical SLEDAI-2K = 0), accrual of organ damage, flares and side effects were documented. RESULTS Ninety-one patients were included [94.5% women, mean (SD) age 45.9 (12.5) years]. Most frequent manifestations were arthritis (76.7%), rash (72.5%), serologic activity (low C3/C4 and/or high anti-dsDNA; 54.9%), hair loss (47.2%) and mucosal ulcers (27.5%). Median (range) duration of treatment was 10.5 (3.0-42.1) months. Belimumab significantly decreased average SLEDAI-2K, physician global assessment (PGA) and daily prednisone dose over time, as early as 3 months after initiation, with over 20% of patients discontinuing corticosteroids. Although reduction in clinical (i.e., excluding serology) SLEDAI-2K was more pronounced in patients who were serologically active (from 8 to 1.5 at 12 months) as compared to serologically inactive (from 6 to 4) at baseline, attainment of LLDAS did not differ between the two groups and was reached by more than 40% of completer patients after 9-12 months. In addition, the number of flares and severe flares was reduced by 62% and 50%, respectively, during the first 12 months of treatment. Twenty patients (22.0%) discontinued treatment due to inadequate response and two due to side effects potentially related to the drug. CONCLUSIONS In real-life, belimumab is efficacious in achieving low disease activity in over 40% of unselected patients, in combination with reduction of corticosteroid dosage and number of flares. Both serologically active and inactive patients respond to the drug.

Abstract
Background/Objective B-cell activating factor (BAFF) plays an important role in the pathogenesis of systemic lupus erythematosus. However, the role of BAFF in lupus nephritis (LN) is not understood. Our aim was to evaluate the expression of BAFF and its three receptors in renal biopsy samples from patients with LN and investigate a relationship with pathological class. Methods We conducted a prospective descriptive study (2011-2014) on 52 kidney biopsy samples from patients with LN. Immunohistochemistry for BAFF, its receptors (transmembrane activator and calcium modulator and cyclophilin ligand interaction (TACI), protein maturation of B cells (BCMA), and BAFF-receptor (BAFF-R)), and CD20 expression was performed. Samples were scored according to the percentage of cells with positive expression. Results In class II LN, BAFF-R and TACI were not expressed, whereas BCMA and BAFF were lowly expressed in the interstitial inflammatory infiltrates. Proliferative class III/IV had elevated BAFF expression in the glomeruli, and TACI was expressed in interstitial inflammatory infiltrates and the glomeruli. Interestingly, the class IV cases with vasculopathy ( n = 4) had endothelial BAFF expression, which was not visible in thrombotic microangiopathy ( n = 4). Class V was characterized by low BAFF expression in interstitial inflammatory infiltrates and by BAFF, TACI, and BCMA expression in the glomeruli. BAFF expression was associated with inflammatory scores and CD20 positive infiltrates, mainly in class IV. Conclusions Expression patterns of BAFF and its receptors differ according to LN class. Our study provides evidence that BAFF could be used as a routine marker in LN biopsies and to determine which patients will benefit from anti-BAFF therapy.

Abstract
The steadily increasing knowledge regarding pathogenetic mechanisms in autoimmune rheumatic diseases has paved the way to different therapeutic approaches. In particular, the market entry of biologics has dramatically modified the natural history of rheumatic chronic inflammatory diseases with a meaningful impact on patients’ quality of life. Among the wide spectrum of available biological treatments, rituximab (RTX), first used in the treatment of non-Hodgkin’s lymphoma, was later approved for rheumatoid arthritis and anti-neutrophil cytoplasmic antibodies-associated vasculitis. Nowadays, in rheumatology, RTX is also used with off-label indications in patients with systemic sclerosis, Sjögren’s syndrome and systemic lupus erythematosus. RTX is a monoclonal antibody directed to CD20 molecules expressed on the surfaces of pre-B and mature B lymphocytes. It acts by causing apoptosis of these cells with antibody- and complement-dependent cytotoxicity. As inflammatory responses to cell-associated immune complexes are key elements in the pathogenesis of several autoimmune rheumatic diseases, such an approach might be effective in these patients. In fact, RTX, by promoting the rapid and long-term depletion of circulating and lymphoid tissue-associated B cells, leads to a lower recruitment of these effector cells at sites of immune complex deposition, thus reducing inflammation and tissue damage. RTX is of the most interest to rheumatologists as it represents an important additional therapeutic approach. Thus, the advent in clinical practice of approved RTX biosimilars, such as CT-P10, may be of help in improving treatment access as well as in reducing costs.

Abstract
Biologic therapy is still limited in lupus, where chronic steroid exposure and wide-spectrum immunosuppression are major triggers of organ damage. In this viewpoint, the authors summarize their views for a "half-full or half-empty" glass on targeted therapy in SLE. The are several reasons for seeing the glass half-empty and in this section the authors propose a critical reflection on scarceness of novel targeted lupus therapies. They show how hard it is to identify suitable biological and clinical targets and to choose the patients that may best fit those targets, as well as to stratify patients according to disease subtype and response, all contributing to the final outcome. On the other hand, reasons are emerging to see the glass half-full, including the growing evidence that disease activity and damage can both be hindered by the proper use of novel drugs and that promising molecules are upcoming. In this section, the authors contextualize potentials and failures of new drugs, providing a critical reading of disappointing results and underlining the concrete benefits obtainable through a wise use of available treatments. Indeed, combining medications with new therapeutic strategies such as the treat-to-target seems the right approach to add some water to a filling glass.

Abstract
INTRODUCTION Lupus Nephritis (LN) is a severe manifestation of Systemic Lupus Erythematosus (SLE) with a significant prognostic impact. Over a prolonged course, an exhaustion of treatment alternatives may occur and further therapeutic options are needed. B cells play a pivotal role in disease pathogenesis and represent an attractive therapeutic target. Areas covered: This review provides an update regarding targeting B cells in LN. The rational for this approach, as well as currently available and future targets are discussed. Expert commentary: Despite its wide clinical use and the encouraging results from retrospective studies, a role of rituximab in LN has not been prospectively confirmed. Trial design methodologies as well as intrinsic limitations of this approach may be responsible and rituximab use is currently limited as a rescue treatment or in settings where a strong steroid sparing effect is warranted. Despite belimumab now being licensed for use in SLE, the evidence in LN is weak although prospective trials are on-going. The combination of different targeted approaches as well as a focus on new clinical end-points may be strategies to identify new therapeutic options.

Abstract
Sjögren Syndrome (SS) is a systemic autoimmune disease with a wide clinical spectrum that extends from sicca symptoms of the mucosal surfaces to extra-glandular systemic manifestations. Understanding of the pathophysiology of primary SS has advanced over recent years, and this, in turn, has presented new targeted treatment options. We provide a brief, up-to-date description of the pathophysiology of SS and the main etiopathogenic pathways implicated in the disease process and review clinical evidence in support of new treatment options targeting these pathways, highlighting successes and failures, and concluding with a summary of gaps in knowledge and where future research should be focused. Direct and indirect B-cell targeted therapies are currently the most promising biological agents in primary SS, especially for systemic involvement, but other pathways (T-cell co-stimulation, cytokine-based therapies, intracellular pathways and gene therapies) are under development. The next 10 years may witness a disruptive therapeutic scenario in primary SS.

Abstract
Patients affected with systemic lupus erythematosus (SLE) still display increased mortality and decreased quality of life in respect to general population. The major determinant of poor long term prognosis is organ damage, which is predictive of more damage and death. Damage is in turn triggered by uncontrolled disease activity and especially by the long-standing corticosteroid use which often accompanies SLE patients over their disease course, owing both to the need of reaching disease remission and to the habit of keeping patients on a small steroid dose for an indefinite period of time. Hence, the need for new drugs and therapeutic strategies aiming at minimizing damage accrual through a better control of disease activity and a steroid-sparing potential is paramount. So far, however, the therapeutic strategy in SLE requires a multitarget approach which is not devoid of widespread immunesuppression. In fact, several studies have been carried out in recent years targeting both the adaptive and the innate immune system, the majority of which did not achieve their primary endpoint, being often divergent from successful clinical experience and thereby committing physician to off-label use of targeted therapies in face of refractory SLE manifestations. The study designs and the chosen endpoints were often blamed for inadequacy, being at least in part responsible for study failures. In this review, we go over major clinical trials conducted in SLE by analyzing any critical aspects related to study design, predefined endpoints and biological activity of novel compounds that may have hampered study outcome, despite the great effort of providing less toxic drugs within a targeted, pathogenic-based approach.
