Predictors and prognostic factors influencing outcomes of anti-CD20 monoclonal antibodies in systemic lupus erythematosus: A systematic review update. Semin Arthritis Rheum 2024; 65:152346. [PMID: 38185077 DOI: 10.1016/j.semarthrit.2023.152346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 10/09/2023] [Accepted: 12/05/2023] [Indexed: 01/09/2024]
Abstract
BACKGROUND Anti-C20 monoclonal antibodies (MAb), such as rituximab, are commonly used for the treatment of patients with severe or refractory systemic lupus erythematosus (SLE) but clinical outcomes are highly variable. We aimed to provide an update of a systematic review of predictive and prognostic factors of anti-CD20 MAb treatment in SLE. METHODS A systematic literature search was undertaken to identify predictive and prognostic factors of clinical response following treatment with anti-CD20 therapies in SLE patients. Studies examining rituximab published prior to 2015 were excluded. Risk of bias was assessed for randomized controlled trials (RCTs) using the Cochrane Collaboration (RoB2) tool for RCTs and the Quality In Prognosis Studies Tool (QUIPS) for cohort studies. A narrative synthesis of the evidence was undertaken and quality of evidence (QoE) was assessed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS From 850 studies identified, 17 studies met the inclusion criteria. A further 8 studies were identified and included through search updates. There were two post-hoc analyses of RCTs of rituximab, one RCT of ocrelizumab and one of obinutuzumab; and 16 cohort studies examining rituximab treatment. The overall QoE was low or very low. There was wide heterogeneity in definitions of clinical disease activity and outcome measures, non-standardized laboratory cut-offs, failure to account for confounders and multiple subgroup analyses of differing outcomes. B cell depletion as well as novel biomarkers, such as S100 proteins, FCGR genotype, anti-vimentin and anti-drug antibodies showed some evidence of prognostic value but QoE was limited due to moderate to high risk of bias, early phase of investigation and imprecision of results. CONCLUSION There has been no validation of previously identified prognostic factors to guide outcome in anti-CD20 treated lupus patients. Hypothesis-driven studies of several novel markers however, demonstrate prognostic value and require replication and validation to support their use in routine clinical practice. PROSPERO REGISTRATION NUMBER CRD42020220339.

Abstract
OBJECTIVE To evaluate the risk and protective factors of serious infection (SI) in patients with systemic lupus erythematosus (SLE) within 180 days of rituximab (RTX) treatment. METHODS Patients with SLE treated with RTX were analyzed. SI was defined as any infectious disease requiring hospitalization. The clinical characteristics, laboratory profiles, medications, and incidence rate (IR) are presented. Multivariate Cox proportional hazards models and Kaplan-Meier analysis for risk factors of SI were performed. RESULTS A total of 174 patients with SLE receiving RTX treatment were enrolled. The overall IR of SIs was 51.0/100 patient-years (PYs). Pneumonia (30.4/100 PYs), followed by soft tissue infections, intra-abdominal infections, and Pneumocystis jiroveci pneumonia (all 6.1/100 PYs) were the leading types of SIs. Twelve patients died during the 180-day follow-up (crude mortality rate: 14.6/100 PYs). Chronic kidney disease (CKD), defined as an estimated glomerular filtration rate < 60 mL/min/1.73 m2 (hazard ratio [HR] 2.88, 95% CI 1.30-6.38), and a background prednisolone (PSL) equivalent dosage ≥ 15 mg/day (HR 3.50, 95% CI 1.57-7.78) were risk factors for SIs among all patients with SLE. Kaplan-Meier analysis confirmed the risk of SI for patients with SLE with CKD and a background PSL equivalent dosage ≥ 15 mg/day (log-rank P = 0.001 and 0.02, respectively). Hydroxychloroquine (HCQ) reduced the risk of SIs in patients with SLE (HR 0.35, 95% CI 0.15-0.82; log-rank P = 0.003). CONCLUSION SI was prevalent in patients with SLE after RTX treatment. Patients with SLE with CKD and high-dose glucocorticoid use required constant vigilance. HCQ may reduce the risk of SI among patients with SLE administered RTX.

Abstract
BACKGROUND Lupus nephritis (LN) is associated with poor outcomes and a significant risk of progression to end-stage renal disease (ESRD). Some patients with resistant LN do not respond adequately to current treatment options and need alternative strategies or therapies. OBJECTIVE The objective is to evaluate the efficacy and safety of rituximab as a re-induction therapy (Re-RTX) followed by maintenance therapy for patients with resistant LN. METHODS Twenty-four patients with resistant LN (failed initial induction therapy or severe relapse after remission) were analyzed. Re-RTX was co-administered with other immunosuppressants. The primary KDIGO criteria outcomes included renal response (complete and partial), disease progression, relapses, and infections. RESULTS The median age was 28 years (IQR 24.5-42), and the female-to-male ratio was 11:1. All patients had active LN, and 91.3% had proliferative LN. Baseline creatinine was 1.075 mg% (IQR 0.7-1.38), and mean urine protein-to-creatinine ratio (UPCR) was 4.9 (IQR 2.8-6.65). Of the patients receiving RTX as re-induction therapy, 66.6% (16/24) had failed initial induction therapy with other immunosuppressants, whereas 33.3% (8/24) had severe relapse during maintenance therapy.Re-RTX had a favorable renal response at 6 months, with 91.7% of the patients responding (20.8% complete response and 70.8% partial response). At 12 months, 58.3% of the patients maintained a renal response (25% complete response and 33.3% partial response). Approximately one-third of patients relapsed within a year.Fourteen patients (58.3%) continued RTX maintenance therapy with two different treatment regimens. At 6 months, Regimen-1 (500 mg every 6 months) resulted in a partial response in 43% (3/7) and relapse in 57% (4/7) of patients. Regimen 2 (1 g dose per year) achieved a complete response in 28.5% (2/7) and a partial response in 71.5% (5/7) with no relapses at 6 months.At a median follow-up of 29 months, adverse renal outcomes were observed in 29.16% of the patients with progression to advanced chronic kidney disease (CKD) or end-stage renal disease (ESRD). The overall use of Re-RTX was considered safe, with a reported infection prevalence of 16%, which is comparable to the existing data. CONCLUSION Re-RTX demonstrated efficacy and safety as an induction therapy for resistant LN. However, the response waned after 1 year, underscoring the need for optimized maintenance therapy.

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

Abstract
Systemic lupus erythematosus (SLE), the prototype of systemic autoimmune diseases is characterized by extreme heterogeneity with a variable clinical course. Renal involvement may be observed and affects the outcome. Hydroxychloroquine should be administered to every lupus patient irrespective of organ involvement. Conventional immunosuppressive therapy includes corticosteroids, methotrexate, cyclophosphamide, mycophenolate mofetil, azathioprine, cyclosporine and tacrolimus. However, despite conventional immunosuppressive treatment, flares occur and broad immunosuppression is accompanied by multiple side effects. Flare occurrence, target organ involvement, side effects of broad immunosuppression and increased knowledge of the pathogenetic mechanisms involved in SLE pathogenesis as well as the availability of biologic agents has led to the application of biologic agents in SLE management. Biologic agents targeting various pathogenetic paths have been applied. B cell targeting agents have been used successfully. Belimumab, a B cell targeting agent, has been approved for the treatment of SLE. Rituximab, an anti-CD20 targeting agent is also used in SLE. Anifrolumab, an interferon I receptor-targeting agent has beneficial effects on SLE. In conclusion, biologic treatment is applied in SLE and should be further evaluated with the aim of a good treatment response and a significant improvement in quality of life.

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.

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
OBJECTIVE To investigate the efficacy and safety of rituximab (RTX) maintenance therapy compared with traditional immunosuppressive agent (ISA) maintenance therapy in patients with relapsing or refractory SLE. METHODS It is a prospective observational non-randomized cohort study. The study enrolled SLE patients in four centres who had received at least one course of RTX induction treatment. Patients with a clinical response to RTX were divided into two groups based on their maintenance therapy in the first 12 months: the RTX group and the ISA group. The relapse-free survival times were compared between the two groups. Univariate and multivariate analyses were conducted to identify predictive factors for disease relapse. RESULTS Among the 82 patients included in the cohort, 67 (81.7%) patients had a clinical response at 6 months. RTX maintenance therapy was applied in 34 (50.7%) patients and ISA maintenance therapy was applied in the remaining 33 (49.3%) patients. After a median follow-up of 24 months, a total of 13 (19.4%) patients had experienced disease relapse, comprising three in the RTX group and 10 in the ISA group. Patients in the RTX group had a higher relapse-free survival rate than patients in the ISA group. Multivariate analysis identified hydroxychloroquine use, RTX maintenance therapy and haematological system involvement as independent predictors for sustained remission. CONCLUSION This multicentre prospective cohort study demonstrated that long-term RTX maintenance therapy has high efficacy and acceptable safety in relapsing or refractory SLE patients who had a clinical response to RTX induction therapy.

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
The prevalence of systemic lupus erythematosus (SLE) is higher in Asians than Caucasians, with higher frequency of renal and other major organ manifestations that carry a poorer prognosis. The outcome of SLE is still unsatisfactory in many parts of the Asia Pacific region due to limited access to healthcare systems, poor treatment adherence and adverse reactions to therapies. The Asia Pacific League of Associations for Rheumatology (APLAR) SLE special interest group has recently published a set of consensus recommendation statements for the management of SLE in the Asia Pacific region. The current article is a supplement of systematic literature search (SLR) to the prevalence and treatment of non-renal manifestations of SLE in Asian patients.

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
BACKGROUND The rates and causes of significant hepatotoxicity with cancer chemotherapy (CCT) in patients infected with hepatitis C virus (HCV) are incompletely characterized. METHODS We compared rates of grade 3 or 4 hepatotoxicity, defined as elevated transaminases, during CCT in patients who are mono-infected with HCV compared with rates in controls matched on demographics, diagnosis, and rituximab use. We excluded patients with hepatobiliary cancers, hepatitis B virus or human immunodeficiency virus infection. Hepatotoxicity was attributed to a medical cause, cancer progression, or CCT, including HCV flare. RESULTS Patients with HCV (n = 196) had a higher rate of cirrhosis than the 1,130 matched controls (21.9% versus 4%; P <0.001). Their higher rate of overall hepatotoxicity (8.7% versus 4.5% of controls, P = 0.01) was due to higher rate of CCT-related hepatotoxicity (4.1% versus 1.2%, P = 0.01). On multivariable analysis, the largest risk factor for overall hepatotoxicity was cirrhosis, and the only risk factor for CCT-related hepatotoxicity was HCV infection. Among those with HCV, the only significant risk factor for hepatotoxicity was rituximab use. Hepatotoxicity caused by CCT delayed or altered treatment in only 3 HCV patients and 1 control (1.5% versus 0.1%, P = 0.01). CONCLUSIONS Most patients with HCV can safely be treated with cancer chemotherapy. Cirrhosis and HCV infection contributed to increased hepatotoxicity in subjects on CCT. Among HCV patients, rituximab use was the major risk factor for increased hepatotoxicity. Hepatotoxicity due to CCT itself rarely altered or delayed CCT. Nonetheless, HCV-positive patients should be monitored carefully during CCT.

Abstract
B cell-targeted therapies have evolved as established therapies for systemic lupus erythematosus (SLE); however, existing approaches still do not thoroughly satisfy clinical requirements due to limited efficacy against memory B cells, autoantibody-producing plasmablasts and disease heterogeneity. To provide a new treatment option for SLE, we created a novel anti-Igβ antibody with enhanced affinity for Fc gamma receptor (FcγR) IIB called ASP2713. ASP2713 cross-reacted with both human and cynomolgus monkey Igβ and showed increased binding affinity for human and monkey FcγRIIB compared to native human IgG1. This binding property allows dominant B cell binding and induction of intrinsic negative feedback signals. In human B cells, ASP2713 significantly and concentration-dependently induced FcγRIIB ITIM phosphorylation, while suppressing proliferation under B cell receptor stimulation. This pharmacological effect was also confirmed in in vitro B cell proliferation and antibody production assays using peripheral B cells isolated from patients with SLE. In a cynomolgus monkey tetanus toxoid-induced antibody production model, ASP2713 almost completely inhibited the increase in antigen-specific antibodies with superior efficacy to rituximab. Additionally, ASP2713 significantly suppressed recall antibody production in response to secondary tetanus toxoid immunization, indicating the memory B cell- and plasmablast-targeting potential of ASP2713. Our results suggest that ASP2713 may have therapeutic potential as a treatment for SLE, where B cells play a pathogenic role.

Abstract
OBJECTIVES The monoclonal anti-CD20 antibody rituximab is frequently applied in the treatment of lymphoma as well as autoimmune diseases and confers efficient depletion of recirculating B cells. Correspondingly, B cell-depleted patients barely mount de novo antibody responses during infections or vaccinations. Therefore, efficient immune responses of B cell-depleted patients largely depend on protective T cell responses. METHODS CD8+ T cell expansion was studied in rituximab-treated rheumatoid arthritis (RA) patients and B cell-deficient mice on vaccination/infection with different vaccines/pathogens. RESULTS Rituximab-treated RA patients vaccinated with Influvac showed reduced expansion of influenza-specific CD8+ T cells when compared with healthy controls. Moreover, B cell-deficient JHT mice infected with mouse-adapted Influenza or modified vaccinia virus Ankara showed less vigorous expansion of virus-specific CD8+ T cells than wild type mice. Of note, JHT mice do not have an intrinsic impairment of CD8+ T cell expansion, since infection with vaccinia virus induced similar T cell expansion in JHT and wild type mice. Direct type I interferon receptor signalling of B cells was necessary to induce several chemokines in B cells and to support T cell help by enhancing the expression of MHC-I. CONCLUSIONS Depending on the stimulus, B cells can modulate CD8+ T cell responses. Thus, B cell depletion causes a deficiency of de novo antibody responses and affects the efficacy of cellular response including cytotoxic T cells. The choice of the appropriate vaccine to vaccinate B cell-depleted patients has to be re-evaluated in order to efficiently induce protective CD8+ T cell responses.

Abstract
As the world navigates the coronavirus disease 2019 (COVID-19) pandemic, there is a growing need to assess its impact in patients with autoimmune rheumatic diseases, such as systemic lupus erythematosus (SLE). Patients with SLE are a unique population when considering the risk of contracting COVID-19 and infection outcomes. The use of systemic glucocorticoids and immunosuppressants, and underlying organ damage from SLE are potential susceptibility factors. Most patients with SLE have evidence of high type I interferon activity, which may theoretically act as an antiviral line of defense or contribute to the development of a deleterious hyperinflammatory response in COVID-19. Other immunopathogenic mechanisms of SLE may overlap with those described in COVID-19, thus, studies in SLE could provide some insight into immune responses occurring in severe cases of the viral infection. We reviewed the literature to date on COVID-19 in patients with SLE and provide an in-depth review of current research in the area, including immune pathway activation, epidemiology, clinical features, outcomes, and the psychosocial impact of the pandemic in those with autoimmune disease.

Abstract
OBJECTIVES Although neuropsychiatric involvement in Systemic Lupus Erythematosus (NPSLE) is one of the most complex and troubling manifestations of the disease, validated outcome instruments to be used as sensitive endpoints in controlled clinical trials are lacking. We set out a systematic literature review (SLR) to identify outcome measurement instruments and domains used to assess NPSLE. METHODS The Preferred Reporting Items for systematic reviews and Meta-analysis (PRISMA) guidelines were used. Articles available in English (1967-2020), listed in PubMed, EMBASE, PsycINFO, Cochrane Library and EULAR outcome measures library were screened. All domains and outcome measurement instruments were characterized according to the OMERACT Filter 2.1, considering core areas (manifestations/abnormalities, life impact, death/lifespan, societal/resource use) and contextual factors. RESULTS Of 3,392 abstracts evaluated, 83 studies were included in the SLR (15,974 patients, females 89.9%). Eligible studies included domains and instruments pertinent to all core areas defined by OMERACT, except for "societal/resource use". The most common core areas were "manifestations/abnormalities", covering 10 domains pertinent to laboratory and instrumental markers, indexes and neuropsychiatric dimension (cognitive, neurologic and psychiatric field), and "life impact", covering 7 domains related to physical function (from both the perspective of the patient and the physician), pain and quality of life. CONCLUSION Our study revealed great heterogeneity in the instruments derived from populations with NPSLE and none of these had high-quality evidence. This supports the need to develop and further validate a core domain set and outcome measurement instruments to promote clinical research in this field, enhancing comparability across studies.

Abstract
PURPOSE This article describes the neurologic manifestations of systemic autoimmune diseases. RECENT FINDINGS Systemic autoimmune diseases can be associated with a wide spectrum of neurologic comorbidities involving the central and peripheral nervous systems. Systemic lupus erythematosus (SLE) can be associated with a number of manifestations predominantly affecting the central nervous system (CNS), whereas peripheral neuropathy is less common. Sjögren syndrome can be associated with peripheral neuropathy in 10% of cases and CNS disease in 2% to 5% of cases. The risk of stroke is increased in SLE, rheumatoid arthritis, temporal arteritis, psoriatic arthritis, and ankylosing spondylitis. Systemic vasculitides present most commonly with mononeuritis multiplex but can also affect the CNS. Cognitive dysfunction is a common symptom among patients with systemic autoimmune diseases, most commonly seen in patients with SLE or Sjögren syndrome. SUMMARY Neurologic manifestations of systemic autoimmune disease are important to recognize, as they may often be the presenting manifestation leading to diagnosis of the systemic disease or may be associated with increased morbidity, other complications, or mortality. Timely diagnosis and institution of appropriate treatment, often requiring multidisciplinary care, is essential to minimize morbidity and decrease the risk of permanent neurologic deficits.

Abstract
BACKGROUND The neurological and psychiatric manifestations of systemic lupus erythematosus (NPSLE) are a heterogeneous group of conditions with variable clinical presentation and significant morbidity and mortality. OBJECTIVES Our aim was to comprehensively assess and present the evidence for treatments used in the management of inflammatory NPSLE. METHODS Medline, Embase, CINHAL and Cochrane CENTRAL were searched from 1990 to end of March 2019 using key words that related to NPSLE and treatment. Included studies comprised clinical trials, observational studies or case series with ≥5 patients and sufficient data related to treatment and outcome in NPSLE patients. RESULTS There were 7222 studies identified in the search, of which 90 were included in the review. There was a notable paucity of clinical trials, with only two randomised controlled trials and one pilot study. Treatment categories included corticosteroids (14 studies), cyclophosphamide (18 studies), synthetic DMARDs (7 studies), biologic therapies (14 studies), therapeutic plasma exchange (6 studies), intravenous immunoglobulin (2 studies), autologous stem cell transplant (3 studies), other therapies (8 studies), combination therapies (6 studies), studies with grouped outcome data (5 studies) and observational studies with therapy-specific associations (7 studies). Corticosteroids are accepted as first line treatment in NPSLE and there is low-moderate evidence supporting their benefit. Moderate evidence, based on consistent data in numerous studies and some trial data, supports the use of cyclophosphamide in the treatment of NPSLE. Limited data support some synthetic DMARDs such as mycophenolate, azathioprine and intrathecal methotrexate. In refractory disease, low-moderate evidence supports rituximab therapy and limited evidence supports benefit following autologous stem cell transplant. Regarding adjuvant treatments, limited evidence favours addition of plasma exchange, intravenous immunoglobulin and hydroxychloroquine. There exists very limited data for other therapies. CONCLUSION There are multiple therapeutic options for the management of inflammatory NPSLE including systemic, biologic and interventional therapies; however, currently there is a paucity of high-quality trial data to guide firm recommendations. In order to better understand the optimal treatment of NPSLE and its different subtypes, further well-designed clinical trials are needed.

Abstract
Aims To characterise patients with refractory SLE receiving rituximab biosimilar (CT-P10) and to explore short-term efficacy and safety associated with rituximab biosimilar use. Methods We retrospectively analysed data from the medical records of patients with refractory SLE who received CT-P10 in Ramathibodi Hospital, Mahidol University, Thailand. Baseline characteristics, disease activity (modified Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)), response to treatment at 6 months after CT-P10 and infection over 6 months were recorded. Results Thirty-two patients with SLE received CT-P10 from April 2018 to June 2019. Of these, 29 (90.6%) were female and the mean±SD age was 36.8±15.2 years. The median (IQR) disease duration was 9.5 (1.3–13.0) years. All patients received glucocorticoid treatment and used 1.7±0.1 immunosuppressive agents at baseline, excluding antimalarial drugs. Baseline Systemic Lupus International Collaborating Clinics Damage Index score was 0.5 (0.0–1.0). Overall response, which was defined as a reduction in the modified SLEDAI score of ≥4, was achieved in 25.0% of patients at 6 months. The modified SLEDAI score reduced from 4 (1.3–8.0) at baseline to 1 (0.0–5.8) at 6 months (p=0.005). Response by active organ involvement was 71.8%. Serious infection occurred in four patients (12.5%), resulting in one death. The median time of onset of infection after CT-P10 infusion was 35.5 (17.0–72.5) days. Conclusion Rituximab biosimilar is associated with improvement in active organ involvement in patients with refractory SLE. Infection occurred early after rituximab biosimilar infusion.

Abstract
OBJECTIVE Rituximab (RTX) has important usage in rheumatoid arthritis and vasculitis. There remains a need for more, better, and safer treatments for patients with lupus nephritis (LN). RTX has been trialed in such patients without definitive conclusions about its effectiveness. As a role for RTX has not been clearly established for LN, we carried out a systematic review and analysis. METHODS We identified 31 studies of RTX for class I-VI LN, and assessed complete renal response (CRR) and partial renal response (PRR) using criteria including serum creatinine, proteinuria, and urinary sediment. Due to differences in the pediatric presentation of the disease, studies focusing on pediatric patients were excluded. RESULTS One randomized controlled trial (RCT) showed superiority of RTX+cyclophosphamide (CYC) versus CYC alone (64% vs. 21% CRR and 19% vs. 36% PRR). Six prospective and retrospective studies utilizing RTX monotherapy found 66% CRR or PRR in all patients. Eleven studies that investigated RTX in combination with CYC or mycophenolate mofetil (MMF) also found 66% CRR or PRR in all patients. In total, the CRR for Caucasian, East Asian, and Hispanic patients were 77%, 38%, and 28%, respectively. CONCLUSIONS RTX appeared to benefit certain LN patients, but most studies were not randomized or properly controlled, were heterogeneous in design, subjects, and LN types, and were not comparable, and must therefore be interpreted cautiously. RTX alone may not deplete B cells sufficiently for the perturbations of LN. In addition, RTX may induce responses differently among patients of different ethnic and racial backgrounds. Furthermore, there were wide variations in the baseline characteristics of the patients, namely LN class, time course of disease, age, and prior immunosuppressive use. We suggest a prospective RCT in patients aged 18-65 years with class IV LN. Ideally, the patients would not have received prior immunosuppression and would better represent different ethnicities. The treatment groups would be RTX, RTX+belimumab, CYC, and MMF groups, with pulse-dose steroids during induction followed by maintenance steroids and MMF. The CRR and PRR would be assessed at 12 and 24 months. This or a similar study might clarify RTX's role in the treatment of LN.

Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is an autoimmune disorder that affects almost every organ system and it is treated with immunomodulation and immunosuppression. SLE patients have an intrinsically dysfunctional immune system which is exacerbated by disease activity and leaves them vulnerable to infection. Treatment with immunosuppression increases susceptibility to infection, while hydroxychloroquine use decreases this risk. Infectious diseases are a leading cause of hospitalization and death. AREAS COVERED This narrative review provides an overview of recent epidemiology and predictors of infections in SLE, delineates the risk of infection by therapeutic agent, and provides suggestions for risk mitigation. Articles were selected from Pubmed searches conducted between September 2019 and January 2020. EXPERT OPINION Despite the large burden of infection, effective and safe preventative care such as universal hydroxychloroquine use and vaccination are underutilized. Future efforts should be directed to quality improvement, glucocorticoid reduction, and validation of risk indices that identify patients at the highest risk of infection.

Abstract
As glucocorticoids and immunosuppressive drugs are non‐specific therapeutic agents that cause many adverse reactions, the development of biologicals aiming to control specific molecular targets is anticipated for the treatment of systemic lupus erythematosus (SLE). The antibody targeting B cell‐activating factor belonging to the tumor necrosis factor family (BAFF) belimumab was the first biological approved for SLE. At present, many biologicals, such as anifrolumab (anti‐type I interferon receptor antibody) and ustekinumab (antibody against interleukin 12/23 [p40]), are in clinical trials. Thus, successful treatments with biologicals targeting “bridging cytokines” produced by dendritic cells, which form a bridge between the innate and acquired immune/autoimmune systems, is of particular interest. Moreover, a phase IIb clinical trial of baricitinib, a low‐molecular‐weight compound targeting Janus kinase 1/2, in patients with SLE revealed that baricitinib was significantly more effective for relieving arthritis and skin manifestations than placebo, and the trial met the primary endpoint. In the future, it is expected that drugs with better efficacy and safety profiles will be used to apply therapeutic strategies, such as precision medicine, in which different molecular target drugs are used for patients classified by their conditions, and to set a therapeutic goal of the discontinuation of glucocorticoids.

Immunoglobulin Binding Protein 1 as a Potential Urine Biomarker in Patients with Lupus Nephritis. Int J Mol Sci 2019; 20:ijms20102606.

Abstract
We evaluated the role of immunoglobulin binding protein 1 (IGBP1), a phosphoprotein associated with the B cell receptor (BCR) complex, as a urine biomarker in lupus nephritis (LN). The IGBP1 concentrations in plasma and urine of patients with LN, systemic lupus erythematosus (SLE) without nephritis and healthy controls were estimated by ELISA. IGBP1 expression in the kidneys of LN patients and transplantation donors was detected by immunohistochemistry. Microarray-based global gene expression profile of HK-2 cells with IGBP1 knock-down and fluorescence-activated cell sorting (FACS) for intracellular IGBP1 expression in human peripheral blood mononuclear cells (PBMCs) was performed. Urine IGBP1 levels were elevated significantly in LN patients, and it correlated with the clinical activity indices (complement 3 (C3) level, anti-dsDNA antibodies titer, SLE Disease Activity Index-2000 (SLEDAI-2K) and histological activity index. IGBP1 expression was increased in LN patients as compared to the donors and was detected mainly in the tubules by histopathology. In microarray analysis, several genes related to SLE pathogenesis (PPME1, ROCK2, VTCN1, IL-17R, NEU1, HLA-DM, and PTX3) responded to siRNA-mediated IGBP1 silencing. In FACS, IGBP1 was expressed mainly in the CD14+ cells. The overall expression of IGBP1 in PBMCs was higher in LN patients as compared with that in SLE patients without nephritis. Conclusively, urinary IGBP1 may be a novel biomarker reflecting the clinical and histological activities in LN.

Abstract
Systemic lupus erythematosus (SLE) is a representative autoimmune disease characterized by multiple organ manifestations but is molecularly and genetically heterogeneous which makes difficult to manage every case based on one kinetic molecular theory. We, therefore, have tried to obtain a broader perspective on the molecular heterogeneity in SLE by immunophenotyping and found that patients with active SLE can be divided into 3 subgroups based on T cell heterogeneity. Although immunophenotypic features were different even among patients with similar clinical features, patients resistant to treatment were most frequently seen in the follicular helper T cell-dominant group. Because belimumab is only approved targeted therapy for SLE, the concept was encompassed with psoriatic arthritis (PsA) for which multiple biologics are approved. The obtained results suggest the potential for precision medicine via the strategic selection of different biologics based on the phenotypic differences in peripheral helper T cells in individual patients with PsA. Thus, subgrouping heterogeneous diseases could provide good bases for precision medicine, which would encourage treatment strategies of diseases with high clinical and molecular heterogeneity such as SLE.

Abstract
Refractory lupus nephritis indicates an inadequate response to lupus nephritis therapy. It implies persisting or worsening disease activity despite therapy, but the definition is complicated by the parameters of response, proteinuria and renal function, that do not discriminate clearly between activity and irreversible damage. Understanding the causes of refractory disease and developing treatment strategies is important because these patients are more likely to develop poor outcomes, especially end stage renal disease. This review explores current concepts and definitions of refractory disease and summarises treatment approaches that have been used in observational cohort studies and case series. We highlight the importance of optimising adherence to the prescribed immunosuppressive and supportive measures and avoidance of diagnostic delay. Treatment options include higher dose glucocorticoid, switching between cyclophosphamide and mycophenolate acid derivates, or addition of rituximab, the latter potentially in combination with belimumab. Less evidence supports extracorporeal treatment (plasma exchange or immunoadsorption), calcineurin inhibitors (cyclosporine A or tacrolimus), intravenous immunoglobulin and stem cell transplantation. Improvements in understanding what refractory disease is and how definitions can be integrated into treatment pathways has the potential to enhance lupus nephritis outcomes.

Abstract
Since the inception of rituximab in the 1990s, anti-CD20 monoclonal antibodies have revolutionised the treatment of B cell hematological malignancies and have become a cornerstone of modern gold-standard practice. Additionally, the potent efficacy of these agents in depleting the B cell compartment has been used in the management of a broad array of autoimmune diseases. Multiple iterations of these agents have been investigated and are routinely used in clinical practice. In this review, we will discuss the physiology of CD20 and its attractiveness as a therapeutic target, as well as the pharmacology, pre-clinical and clinical data for the major anti-CD20 monoclonal antibodies: rituximab, obinutuzumab and ofatumumab.
