Abstract
Metabolic programming is important for B cell fate, but the bioenergetic requirement for regulatory B (Breg) cell differentiation and function is unknown. Here we show that Breg cell differentiation, unlike non-Breg cells, relies on mitochondrial electron transport and homeostatic levels of reactive oxygen species (ROS). Single-cell RNA sequencing analysis revealed that TXN, encoding the metabolic redox protein thioredoxin (Trx), is highly expressed by Breg cells, unlike Trx inhibitor TXNIP which was downregulated. Pharmacological inhibition or gene silencing of TXN resulted in mitochondrial membrane depolarization and increased ROS levels, selectively suppressing Breg cell differentiation and function while favoring pro-inflammatory B cell differentiation. Patients with systemic lupus erythematosus (SLE), characterized by Breg cell deficiencies, present with B cell mitochondrial membrane depolarization, elevated ROS and fewer Trx+ B cells. Exogenous Trx stimulation restored Breg cells and mitochondrial membrane polarization in SLE B cells to healthy B cell levels, indicating Trx insufficiency underlies Breg cell impairment in patients with SLE.

Abstract
OBJECTIVES Age has a significant impact on systemic lupus erythematosus (SLE). However, data on very late-onset SLE (vlSLE) are scarce. We have compared the clinical and serological features of vlSLE patients with younger-onset patients. METHODS We assessed the clinical and laboratory data of all patients fulfilling SLE classification criteria evaluated at a university hospital from 1978 to 2023. Patients were divided into 4 groups according to age at diagnosis: juvenile SLE (jSLE <8 years); adult SLE (aSLE 18-49 years); late SLE (lSLE 50-59 years); vlSLE (≥60 years). RESULTS 845 patients were enrolled. The jSLE, aSLE, lSLE, and vlSLE groups included 153, 630, 47, and 15 patients, respectively. The vlSLE group tended to have a lower female-to-male ratio (4:1; p=0.282), was mainly Caucasian (93.3%; p<0.001), and had the lowest survival time (20.3 years; p<0.001). vlSLE patients had the lowest prevalence of positive anti-dsDNA antibodies (26.7%; p=0.010) and low C3 levels (13.3%; p<0.001). Although arthritis was less common among vlSLE patients (73.3%; p=0.043), they more commonly developed Sjögren's syndrome (SS 33.3%; p<0.001) and rheumatoid arthritis (RA 13.3%; p<0.001). Infections and malignancy were the main causes of death. CONCLUSIONS Compared with younger patients, in vlSLE, female predominance is less pronounced. Arthritis, anti-dsDNA antibodies and low C3 levels are less frequent. SS and RA are more common. Despite lower disease activity, vlSLE patients have the lowest survival rate. While uncommon, SLE should not be excluded as a possible diagnosis in the elderly.

Abstract
aPLs are a major determinant of the increased cardiovascular risk in patients with SLE. They adversely affect clinical manifestations, damage accrual and prognosis. Apart from the antibodies included in the 2006 revised classification criteria for APS, other non-classical aPLs might help in identifying SLE patients at increased risk of thrombotic events. The best studied are IgA anti-β2-glycoprotein I, anti-domain I β2-glycoprotein I and aPS-PT. Major organ involvement includes kidney and neuropsychiatric systems. aPL/APS severely impacts pregnancy outcomes. Due to increased thrombotic risk, these patients require aggressive cardiovascular risk factor control. Primary prophylaxis is based on low-dose aspirin in high-risk patients. Warfarin is the gold-standard drug for secondary prophylaxis.

Abstract
Idiopathic inflammatory myopathies (IIM) are a rare and heterogeneous group of chronic autoimmune disorders. Up to 40% of IIM patients have long-term sequelae and significant functional disability. Its management can be challenging. New therapies are badly needed. The small number of cases with diverse presentations, and different diagnostic criteria interfere significantly with clinical trial results. Only intravenous immunoglobulin has been internationally approved for IIM patients. Most clinical trials of new biological therapies have failed to meet their primary endpoints in IIM, with only one biological drug recommended for refractory IIM treatment (rituximab), although not approved. We review several new emerging biological drugs including B cell depletion therapies, abatacept, janus-kinase inhibitors, and aldesleukin. Encouragingly, some phase II randomized controlled trials have evaluated the efficacy and safety of new biologics in IIM, demonstrating an improvement in clinical and laboratory measures.

Abstract
Background Life-long anticoagulation increases bleeding risk in patients with antiphospholipid syndrome (APS). The Damage Index for Antiphospholipid Syndrome does not include bleeding events in damage accrual. Objectives We aimed to characterize the prevalence, severity, and damage associated with bleeding events in patients with APS. Methods This was a single-center retrospective analysis of patients with thrombotic APS (2006 Sydney criteria). Bleeding events were reviewed up to 43 years and classified according to the ISTH definitions into 2 groups: 1) major bleedings and 2) nonmajor bleedings (minor bleedings and clinically relevant nonmajor bleedings). Damage events were recorded as bleeding events a) resulting in permanent (>6 months) decrease in organ function and b) complicated by total/partial organ resection. Results Among 197 patients (2412 patient-years [PYs] of follow-up), all of whom had been exposed to antithrombotic therapy, 40.6% experienced 167 bleedings (6.9 events per 100 PYs), of whom 61.3% had nonmajor bleedings (77.2% of bleedings: 42.6% minor, 57.4% clinically relevant nonmajor) and 38.8% had major bleedings (22.8% of bleedings; 1.6 events per 100 PYs). Soft/connective tissue was affected in 44.3% of bleedings, and 94.6% were nonmajor bleedings. Central nervous system was affected in 20.9% of bleedings, and 62.9% were major bleedings. Bleeding events were spontaneous in 90.4% of cases, and thrombocytopenia was likely involved in 62.2% of bleedings. Damage occurred in 11.4% of bleedings and affected 7.6% of patients. Most of the damage was associated with central nervous system events (8.4% of all bleedings). Conclusion Approximately 40% of patients experienced at least 1 bleeding, and almost 8% of patients were left with organ damage not recognized by the current version of the Damage Index for Antiphospholipid Syndrome.

Abstract
OBJECTIVE The goals of this study were to assess the associations of severe nonadherence to hydroxychloroquine (HCQ), objectively assessed by HCQ serum levels, and risks of systemic lupus erythematosus (SLE) flares, damage, and mortality rates over five years of follow-up. METHODS The Systemic Lupus International Collaborating Clinics (SLICC) Inception Cohort is an international multicenter initiative (33 centers throughout 11 countries). The serum of patients prescribed HCQ for at least three months at enrollment were analyzed. Severe nonadherence was defined by a serum HCQ level <106 ng/mL or <53 ng/mL for HCQ doses of 400 or 200 mg/day, respectively. Associations with the risk of a flare (defined as a Systemic Lupus Erythematosus Disease Activity Index 2000 increase ≥4 points, initiation of prednisone or immunosuppressive drugs, or new renal involvement) were studied with logistic regression, and associations with damage (first SLICC/American College of Rheumatology Damage Index [SDI] increase ≥1 point) and mortality with separate Cox proportional hazard models. RESULTS Of the 1,849 cohort participants, 660 patients (88% women) were included. Median (interquartile range) serum HCQ was 388 ng/mL (244-566); 48 patients (7.3%) had severe HCQ nonadherence. No covariates were clearly associated with severe nonadherence, which was, however, independently associated with both flare (odds ratio 3.38; 95% confidence interval [CI] 1.80-6.42) and an increase in the SDI within each of the first three years (hazard ratio [HR] 1.92 at three years; 95% CI 1.05-3.50). Eleven patients died within five years, including 3 with severe nonadherence (crude HR 5.41; 95% CI 1.43-20.39). CONCLUSION Severe nonadherence was independently associated with the risks of an SLE flare in the following year, early damage, and five-year mortality.

Abstract
BACKGROUND The optimal strategy for diagnosis and antithrombotic treatment of patients with antiphospholipid syndrome (APS)-associated acute ischemic stroke (AIS), transient ischemic attack (TIA), or other brain ischemic injury is poorly defined. OBJECTIVES The survey goal was to capture variations in diagnosis and antithrombotic treatment of APS-associated ischemic stroke and related disorders to inform guidance and clinical trials to define optimal management. METHODS Professional colleagues, including key opinion leaders, were invited to complete a REDCap survey questionnaire initiated by the International Society on Thrombosis and Haemostasis Scientific and Standardisation Committee Subcommittee on Lupus Anticoagulant/Antiphospholipid Antibodies. The survey data were tallied using simple descriptive statistics. RESULTS There was generally good agreement on several aspects, including which patients to test for antiphospholipid antibodies (aPL), use of a lifelong vitamin K antagonist for AIS or recurrent TIA, and formal cognitive assessment for suspected cognitive impairment. There was less agreement on other aspects, including aPL testing for brain ischemic injury other than AIS/TIA or if an alternative cause for AIS or TIA exists; choice of aPL tests, their timing, and age cutoff; the aPL phenotype to trigger antithrombotic treatment; management for patent foramen ovale; antithrombotic treatment for first TIA or white matter hyperintensities; head magnetic resonance imaging specifications; and low-molecular-weight heparin dosing/anti-Xa monitoring in pregnancy. The survey highlighted that approximately 25% practice at dedicated APS clinics and <50% have a multidisciplinary team structure for patients with APS. CONCLUSION Much of the variation in practice reflects the lack of evidence-based recommendations. The survey results should inform the development of a more uniform multidisciplinary consensus approach to diagnosis and antithrombotic treatment.

Abstract
OBJECTIVE To estimate direct and indirect costs associated with neuropsychiatric (NP) events in the Systemic Lupus International Collaborating Clinics inception cohort. METHODS NP events were documented annually using American College of Rheumatology definitions for NP events and attributed to systemic lupus erythematosus (SLE) or non-SLE causes. Patients were stratified into 1 of 3 NP states (no, resolved, or new/ongoing NP event). Change in NP status was characterized by interstate transition rates using multistate modeling. Annual direct costs and indirect costs were based on health care use and impaired productivity over the preceding year. Annual costs associated with NP states and NP events were calculated by averaging all observations in each state and adjusted through random-effects regressions. Five- and 10-year costs for NP states were predicted by multiplying adjusted annual costs per state by expected state duration, forecasted using multistate modeling. RESULTS A total of 1,697 patients (49% White race/ethnicity) were followed for a mean of 9.6 years. NP events (n = 1,971) occurred in 956 patients, 32% attributed to SLE. For SLE and non-SLE NP events, predicted annual, 5-, and 10-year direct costs and indirect costs were higher in new/ongoing versus no events. Direct costs were 1.5-fold higher and indirect costs 1.3-fold higher in new/ongoing versus no events. Indirect costs exceeded direct costs 3.0 to 5.2 fold. Among frequent SLE NP events, new/ongoing seizure disorder and cerebrovascular disease accounted for the largest increases in annual direct costs. For non-SLE NP events, new/ongoing polyneuropathy accounted for the largest increase in annual direct costs, and new/ongoing headache and mood disorder for the largest increases in indirect costs. CONCLUSION Patients with new/ongoing SLE or non-SLE NP events incurred higher direct and indirect costs.

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
OBJECTIVES High rates of anti-drug antibodies (ADA) to rituximab have been demonstrated in patients undergoing treatment for SLE. However, little is known with regard to their long-term dynamics, impact on drug kinetics and subsequent implications for treatment response. In this study, we aimed to evaluate ADA persistence over time, impact on circulating drug levels, assess clinical outcomes and whether they are capable of neutralizing rituximab. METHODS Patients with SLE undergoing treatment with rituximab were recruited to this study (n = 35). Serum samples were collected across a follow-up period of 36 months following treatment (n = 114). Clinical and laboratory data were collected pre-treatment and throughout follow-up. ADA were detected via electrochemiluminescent immunoassays. A complement dependent cytotoxicity assay was used to determine neutralizing capacity of ADA in a sub-cohort of positive samples (n = 38). RESULTS ADA persisted over the 36-month study period in 64.3% of patients undergoing treatment and titres peaked earlier and remained higher in those who had previously been treated with rituximab when compared with than those who were previously treatment naive. ADA-positive samples had a significantly lower median drug level until six months post rituximab infusion (P = 0.0018). Patients with persistent ADA positivity showed a significant early improvement in disease activity followed by increased rates of relapse. In vitro analysis confirmed the neutralizing capacity of ADA to rituximab. CONCLUSIONS ADA to rituximab were common and persisted over the 36-month period of this study. They associated with earlier drug elimination, an increased rate of relapse and demonstrated neutralizing capacity in vitro.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease that has diverse clinical manifestations, ranging from restricted cutaneous involvement to life-threatening systemic organ involvement. The heterogeneity of pathomechanisms that lead to SLE contributes to between-patient variation in clinical phenotype and treatment response. Ongoing efforts to dissect cellular and molecular heterogeneity in SLE could facilitate the future development of stratified treatment recommendations and precision medicine, which is a considerable challenge for SLE. In particular, some genes involved in the clinical heterogeneity of SLE and some phenotype-related loci (STAT4, IRF5, PDGF genes, HAS2, ITGAM and SLC5A11) have an association with clinical features of the disease. An important part is also played by epigenetic varation (in DNA methylation, histone modifications and microRNAs) that influences gene expression and affects cell function without modifying the genome sequence. Immune profiling can help to identify an individual's specific response to a therapy and can potentially predict outcomes, using techniques such as flow cytometry, mass cytometry, transcriptomics, microarray analysis and single-cell RNA sequencing. Furthermore, the identification of novel serum and urinary biomarkers would enable the stratification of patients according to predictions of long-term outcomes and assessments of potential response to therapy.

Abstract
OBJECTIVES We aimed to characterise clinical manifestations, disease course, treatment, and mortality of IIM patients. We have also attempted to identify predictors of mortality in IIM. METHODS This was a retrospective single-centre study including IIM patients fulfilling the Bohan and Peter criteria. Patients were divided in 6 groups: adult-onset polymyositis (APM), adult-onset dermatomyositis (ADM), juvenile-onset dermatomyositis, 'overlap' myositis (OM), cancer-associated myositis, and antisynthetase syndrome. Sociodemographic, clinical and immunological features, treatment, and causes of death were recorded. Survival analysis and predictors of mortality was performed using Kaplan-Meier and Cox proportional hazards regression. RESULTS A total of 158 patients were included with a mean age at diagnosis of 40.8±15.6 years. Most patients were female (77.2%) and Caucasian (63.9%). The most frequent diagnoses were ADM (35.4%), OM (20.9%) and APM (24.7%), respectively. Most patients (74.1%) were treated with a combination of steroids and one-to-three immunosuppressive drugs. Interstitial lung disease, gastrointestinal and cardiac involvement affected 38.5%, 36.5% and 23.4% of the patients, respectively. The survival rates at 5, 10, 15, 20 and 25 years of follow-up were 89%, 74%, 67%, 62% and 43%, respectively. During a median follow-up of 13.6±10.2 years, 29.1% have died, infection being the most common cause (28.3%). Older age at diagnosis (HR1.053, 95% CI 1.027-1.080), cardiac involvement (HR 2.381, 95% CI 1.237-4.584), and infections (HR 2.360, 95% CI 1.194-4.661) were independent predictors of mortality. CONCLUSIONS IIM is a rare disease with important systemic complications. Early diagnosis and aggressive treatment of cardiac involvement and infections could improve survival of these patients.

Abstract
OBJECTIVE To determine whether BILAG-2004 index is associated with the development of damage in a cohort of SLE patients. Mortality and development of damage were examined. METHODS This was a multicentre longitudinal study. Patients were recruited within 12 months of achieving fourth ACR classification criterion for SLE. Data were collected on disease activity, damage, SLE-specific drug exposure, cardiovascular risk factors, antiphospholipid syndrome status and death at every visit. This study ran from 1 January 2005 to 31 December 2017. Descriptive statistics were used to analyse mortality and development of new damage. Poisson regression was used to examine potential explanatory variables for development of new damage. RESULTS A total of 273 SLE patients were recruited with total follow-up of 1767 patient-years (median 73.4 months). There were 6348 assessments with disease activity scores available for analysis. During follow-up, 13 deaths and 114 new damage items (in 83 patients) occurred. The incidence rate for development of damage was higher in the first 3 years before stabilizing at a lower rate. Overall rate for damage accrual was 61.1 per 1000 person-years (95% CI: 50.6, 73.8). Analysis showed that active disease scores according to BILAG-2004 index (systems scores of A or B, counts of systems with A and BILAG-2004 numerical score) were associated with development of new damage. Low disease activity (LDA) states [BILAG-2004 LDA and BILAG Systems Tally (BST) persistent LDA] were inversely associated with development of damage. CONCLUSIONS BILAG-2004 index is associated with new damage. BILAG-2004 LDA and BST persistent LDA can be considered as treatment targets.

Abstract
Systemic lupus erythematosus (SLE) is characterized by increased expression of type I interferon (IFN)-regulated genes in 50%-75% of patients. We report that out of 501 patients with SLE analyzed, 73 (14%) present autoantibodies against IFNα (anti-IFN-Abs). The presence of neutralizing-anti-IFN-Abs in 4.2% of patients inversely correlates with low circulating IFNα protein levels, inhibition of IFN-I downstream gene signatures, and inactive global disease score. Hallmarks of SLE pathogenesis, including increased immature, double-negative plasmablast B cell populations and reduction in regulatory B cell (Breg) frequencies, were normalized in patients with neutralizing anti-IFN-Abs compared with other patient groups. Immunoglobulin G (IgG) purified from sera of patients with SLE with neutralizing anti-IFN-Abs impedes CpGC-driven IFNα-dependent differentiation of B cells into immature B cells and plasmablasts, thus recapitulating the neutralizing effect of anti-IFN-Abs on B cell differentiation in vitro. Our findings highlight a role for neutralizing anti-IFN-Abs in controlling SLE pathogenesis and support the use of IFN-targeting therapies in patients with SLE lacking neutralizing-anti-IFN-Abs.

Abstract
Background Systemic lupus erythematosus (SLE) is a complex autoimmune disease associated with widespread immune dysregulation and diverse clinical features. Immune abnormalities might be differentially associated with specific organ involvement or response to targeted therapies. We aimed to identify biomarkers of response to belimumab after rituximab to facilitate a personalised approach to therapy. Methods In this exploratory analysis of a randomised controlled trial (BEAT-LUPUS), we investigated immune profiles of patients with SLE recruited to the 52-week clinical trial, which tested the combination of rituximab plus belimumab versus rituximab plus placebo. We used machine learning and conventional statistics to investigate relevant laboratory and clinical biomarkers associated with major clinical response. BEAT LUPUS is registered at ISRCTN, 47873003, and is now complete. Findings Between Feb 2, 2017, and March 28, 2019, 52 patients were recruited to BEAT-LUPUS, of whom 44 provided clinical data at week 52 and were included in this analysis. 21 (48%) of 44 participants were in the belimumab group (mean age 39·5 years [SD 12·1]; 17 [81%] were female, four [19%] were male, 13 [62%] were White) and 23 (52%) were in the placebo group (mean age 42·1 years [SD 10·5]; 21 [91%] were female, two [9%] were male, 16 [70%] were White). Ten (48%) of 21 participants who received belimumab after rituximab and eight (35%) of 23 who received placebo after rituximab had a major clinical response at 52 weeks (between-group difference of 13% [95% CI -15 to 38]). We found a predictive association between baseline serum IgA2 anti-double stranded DNA (dsDNA) antibody concentrations and clinical response to belimumab after rituximab, with a between-group difference in major clinical response of 48% (95% CI 10 to 70) in patients with elevated baseline serum IgA2 anti-dsDNA antibody concentrations. Moreover, among those who had a major clinical response, serum IgA2 anti-dsDNA antibody concentrations significantly decreased from baseline only in the belimumab group. Increased circulating IgA2 (but not total) plasmablast numbers, and T follicular helper cell numbers predicted clinical response and were both reduced only in patients who responded to belimumab after rituximab. Serum IgA2 anti-dsDNA antibody concentrations were also associated with active renal disease, whereas serum IgA1 anti-dsDNA antibody and IFN-α concentrations were associated with mucocutaneous disease activity but did not predict response to B-cell targeted therapy. Patients with a high baseline serum interleukin-6 concentration were less likely to have a major clinical response, irrespective of therapy. Interpretation This exploratory study revealed the presence of distinct molecular networks associated with renal and mucocutaneous involvement, and response to B-cell-targeted therapies, which, if confirmed, could guide precision targeting of advanced therapies for this heterogenous disease.

Abstract
OBJECTIVE Antiphospholipid antibodies (aPL) are found in the blood of 20-30% of patients with systemic lupus erythematosus (SLE). Although aPL cause vascular thrombosis in the antiphospholipid syndrome it is not clear whether positive aPL levels in early SLE increase risk of subsequent vascular events (VE). In a previous analysis of 276 patients with SLE, we found that early positivity for ≥2 of IgG anti-cardiolipin (anti-CL), IgG anti-beta2glycoprotein I (anti-β2GPI) and anti-Domain I of beta2glycoprotein I (anti-DI) showed a possible association with VE. Here we have extended that analysis. METHODS Serum samples taken from 501 patients with SLE early in their disease had been tested for IgG anti-CL, anti-β2GPI and anti-DI by ELISA. Complete VE history was available for 423 patients of whom 23 were excluded because VE occurred before the diagnosis of SLE. For the remaining 400 patients we carried out Kaplan-Meier survival analysis to define groups at higher risk of VE. RESULTS Of 400 patients, 154 (38.5%) were positive for one or more aPL; 27 (6.8%) were double/triple-positive and 127 (31.8%) were single-positive. There were 91 VE in 77 patients, of whom 42 were aPL-positive in early disease. VE were significantly increased in aPL-positive versus aPL-negative patients (p= 0.041) and in double/triple-positive versus single-positive versus aPL-negative patients (p= 0.0057).Omission of the IgG anti-DI assay would have missed 14 double/triple-positive patients of whom 6 had VE. CONCLUSION Double/triple-positivity for IgG anti-CL, anti- anti-β2GPI and anti-DI in early SLE identifies a population at higher risk of subsequent VE.

Abstract
OBJECTIVES To investigate key factors that may contribute to the variability of rituximab-mediated peripheral and renal B cell depletion (BCD) in SLE. METHODS We analysed: (i) CD19+ B cell counts in patients with SLE before and 1, 2, 3 and 6 months after treatment with rituximab, comparing them with RA patients; (ii) the presence of B cells in renal biopsies after rituximab therapy; (iii) whether the duration of BCD correlated with patient demographics and B cell expression of CD20 and FcγRIIb; and (iv) the effect of B cell activation factor (BAFF) on the efficiency of rituximab and obinutuzumab at inducing BCD in whole blood assays, in vitro. RESULTS In SLE (n = 71), the duration of BCD was shorter compared with RA (n = 27). B cells were detectable in renal biopsy samples (n = 6) after treatment with rituximab in all patients with poor response while peripheral blood B cells remained low or undetectable in the same patients. There were no significant relationships between peripheral BCD and patient age, disease duration, serum C3 levels or the level of expression of B cell surface proteins CD20 and FcγRIIb. Obinutuzumab was more efficient than rituximab at inducing BCD in whole blood assays, regardless of excess BAFF. CONCLUSIONS BCD in SLE is less efficient than in RA. Renal B cell presence following rituximab treatment was associated with poor outcomes. No significant relationships between any measured B cell related, clinical or laboratory parameters and the efficiency of BCD by rituximab was found. Obinutuzumab was superior to rituximab at inducing BCD.

Abstract
OBJECTIVE To identify clinical and serological features that distinguish patients with SLE who require single as opposed to repeated rituximab (RTX) cycles. METHODS All 175 SLE patients followed up at University College Hospital from 2000 onwards were retrospectively reviewed. They were divided into a one-RTX-cycle group and a multiple-cycle group (2 or more cycles). Patients included had a follow-up of at least 3 years after their first RTX cycle, unless they needed a second infusion sooner. RESULTS A total of 131 patients were included; 44 (33.6%) received one cycle of RTX and 87 (66.4%) received two or more. The former were older at diagnosis (31.4 vs 21 years, P < 0.001) and at first RTX infusion (39.9 vs 29 years, P < 0.001). This group of patients had more organs/systems involved (P = 0.044), more leukopenia, lymphopenia and thrombocytopenia (P = 0.001, P < 0.0001 and P = 0.003, respectively) and lower C3 levels (P = 0.035). They also had fewer immunosuppressive drugs before RTX therapy compared with those who required multiple RTX cycles (P = 0.003). There was no statistical difference in either the clinical or serological response after the first RTX cycle between both groups. Furthermore, patients who had received more immunosuppressive treatments were more likely to require more than one cycle of RTX infusions (P = 0.007). CONCLUSIONS RTX is an effective option for SLE patients with severe flares. Patients who received more immunosuppressive drugs were more likely to receive more than one set of RTX infusions. This suggests that RTX is best used for SLE patients with no history of refractory disease.

Abstract
OBJECTIVE Patients with SLE have increased prevalence of clinical cardiovascular disease (CVD) and subclinical atherosclerosis. Although 30-40% of patients with SLE have vascular plaque on ultrasound scanning, this study is the first to consider the relationship between total burden of plaque and subsequent CVD risk. METHODS One hundred patients with SLE and without any previous clinical CVD underwent vascular ultrasound scans of both carotid and both common femoral bifurcations between 2011 and 2013. Clinical, serological, demographic and treatment data were collected at baseline. Patients were followed till 2020 to identify those who developed new onset coronary disease or stroke. Statistical analysis to identify factors associated with increased risk of developing CVD events was carried out. RESULTS Thirty-six patients had plaque at baseline. During follow-up five patients (all had baseline plaque) developed coronary disease and two, without baseline plaque, developed lacunar strokes. Mean (s.d.) age of these patients was 46.5 (4.5) years. Patients with three or more baseline bifurcations with plaque were 10 times more likely to develop CVD than those with 0-2 bifurcations with plaques (OR 9.9, P = 0.009). TPA > 16mm2 was associated with six-fold increased risk of CVD (OR = 6.44, P = 0.028). Patients with disease duration > 14 years were more likely than those with disease duration < 14 years to develop CVD (OR 8.3 P = 0.043). CONCLUSIONS The number of bifurcations with plaque and TPA in patients with SLE may be valuable in assessing risk of CVD and deciding on clinical measures to reduce this risk.

Abstract
Abstract
Background/Aims
Patients with systemic lupus erythematosus (SLE) have increased mortality compared to age- and sex-matched controls. Lupus nephritis (LN) is a severe manifestation of SLE and an important cause of death. Our objective was to carry out a retrospective survival analysis to investigate factors that could influence risk of mortality and LN in a large multi-ethnic cohort of patients with SLE.
Methods
By careful review of medical records, we identified 496 patients with SLE for whom we had complete information regarding period of observation and occurrence of death and nephritis. Patients were stratified into groups according to sex, ethnicity (Caucasian, African/Caribbean, South Asian, East Asian, Other), age at start of follow-up (above and below median) and time-period of diagnosis (1978-89, 1990-99, 2000-5, 2006-11). Kaplan-Meier analysis was used to investigate differences between the groups in survival and LN.
Results
Overall, there were 454 women and 42 men. 91 patients died and 165 developed LN. Mean follow-up was 15.8 ± 8.75 years with a maximum of 40 years. Median age at start of follow-up was 28.0 ± 12.13 years.
Results are shown in Table 1
There were no differences between men and women in mortality or LN.
Caucasian patients were significantly less likely to develop LN (P < 0.0001) than other groups but there was no mortality difference between ethnic groups.
Patients diagnosed below age 28 were more likely to develop LN (P < 0.0001) but less likely to die (P = 0.0039) than those diagnosed above age 28.
Patients diagnosed between 2006 and 2011 were significantly less likely to die than those diagnosed between 1978 and1989 by Cox proportional hazards analysis of survival curves. (P = 0.019)
Conclusion
In this long-term survival analysis of 496 patients, non-Caucasian patients and those diagnosed below the age of 28 years were more likely to develop LN. The latter group were less likely to die than those diagnosed at older ages. Survival curves for groups of patients diagnosed in successive time periods suggested improved survival over time.

There was no difference between men and women in either mortality or development of LN. Caucasian patients were significantly less likely to develop LN than other ethnic groups (P < 0.0001) but not less likely to die. Patients diagnosed before the median age of 28 years were significantly more likely to develop LN (P < 0.0001) but significantly less likely to die (P = 0.0039) during the period of observation. There has been a significant improvement in survival in patients diagnosed between 1978 and 1989 and those diagnosed between 2006 and 2011 (P = 0.019). CONCLUSION In our cohort, non-Caucasian ethnicity and younger age at diagnosis are associated with the risk of developing LN. There is evidence of improvement in survival of patients with SLE over time.

Abstract
OBJECTIVES To determine whether early damage and its kinetics measured by the Damage Index for Antiphospholipid Syndrome (DIAPS) predicts mortality. METHODS We carried out a single-centre retrospective analysis of thrombotic APS patients (2006 Sydney criteria), using the DIAPS for damage assessment. Early damage was considered to be at six months after disease onset; early damage increase (delta-DIAPS) was deemed to be at least a one-point rise in DIAPS within the first five years of illness. Groups were compared using appropriate statistical tests. Survival was analysed by the Kaplan-Meier method. Cox regression analysis was performed to investigate predictors of mortality. RESULTS A total of 197 patients (71.1% female; 65.9% primary APS; 72.4% Caucasian) were followed for up to 43 years (median 10). Damage developed in 143 (73.6%) patients. Twenty-three patients (12%) died. Secondary APS (HR 3.07, 95%CI 1.32-7.12, p=0.009), male sex (HR 3.14, 95%CI 1.35-7.33, p=0.008) and age at APS onset ≥40 years (HR 5.34, 95%CI 1.96-14.53, p=0.001) were risk factors for death. Early damage (n=69, 35.0%) was not associated with death (p=0.231). Having a first arterial event was associated with early damage (p<0.001), but not with delta-DIAPS (p=0.539) nor with the risk of death (p=0.151). Delta-DIAPS (n=53/181, 29.3%) predicted mortality (HR 5.40, 95%CI 2.33-12.52, p<0.001), even after adjusting individually for APS category (secondary), sex (male), early damage and age at APS onset (≥40 years) (all p<0.005). CONCLUSIONS Evolving damage in the first five years of illness, but not early damage, predicted mortality regardless of the nature of the first thrombotic event, sex, APS category and age.

Abstract
BACKGROUND B-cell depletion with rituximab is commonly used for patients with systemic lupus erythematosus (SLE) that is refractory to conventional therapy, but it yields variable responses. We hypothesized that high B-cell activating factor (BAFF) levels after rituximab can cause disease flares, thereby limiting its effectiveness. OBJECTIVE To obtain preliminary evidence for efficacy of the anti-BAFF therapeutic belimumab after rituximab in SLE. DESIGN Phase 2, randomized, double-blind (patients, assessors, researchers, care providers), placebo-controlled, parallel-group, superiority trial. (ISRCTN: 47873003). SETTING England. PARTICIPANTS Fifty-two patients who had SLE that was refractory to conventional treatment and whose physicians had recommended rituximab therapy were recruited between 2 February 2017 and 28 March 2019. INTERVENTION Participants were treated with rituximab and 4 to 8 weeks later were randomly assigned (1:1) to receive intravenous belimumab or placebo for 52 weeks. MEASUREMENTS The prespecified primary end point was serum IgG anti-double-stranded DNA (anti-dsDNA) antibody levels at 52 weeks. Secondary outcomes included incidence of disease flares and adverse events. RESULTS At 52 weeks, IgG anti-dsDNA antibody levels were lower in patients treated with belimumab compared with placebo (geometric mean, 47 [95% CI, 25 to 88] vs. 103 [CI, 49 to 213] IU/mL; 70% greater reduction from baseline [CI, 46% to 84%]; P < 0.001). Belimumab reduced risk for severe flare (BILAG-2004 grade A) compared with placebo (hazard ratio, 0.27 [CI, 0.07 to 0.98]; log-rank P = 0.033), with 10 severe flares in the placebo group and 3 in the belimumab group. Belimumab did not increase incidence of serious adverse events. Belimumab significantly suppressed B-cell repopulation compared with placebo (geometric mean, 0.012 [CI, 0.006 to 0.014] vs. 0.037 [CI, 0.021 to 0.081] × 109/L) at 52 weeks in a subset of patients (n = 25) with available data. LIMITATIONS Small sample size; biomarker primary end point. CONCLUSION Belimumab after rituximab significantly reduced serum IgG anti-dsDNA antibody levels and reduced risk for severe flare in patients with SLE that was refractory to conventional therapy. The results suggest that this combination could be developed as a therapeutic strategy. PRIMARY FUNDING SOURCE Versus Arthritis.

Abstract
OBJECTIVES Atacicept reduced SLE disease activity in the phase 2b ADDRESS II study, particularly in patients with high disease activity (HDA; SLEDAI-2K ≥10) at screening. We assessed long-term safety and efficacy of atacicept in the long-term extension (LTE) of ADDRESS II. METHODS In the 24-week, randomized, double-blind, placebo-controlled ADDRESS II study, patients received weekly atacicept (75 or 150 mg) or placebo. Atacicept was continued at the same dose in atacicept-treated patients in the LTE; placebo-treated patients switched to atacicept 150 mg. Long-term safety was the primary endpoint. Secondary endpoints included SLE responder index (SRI)-4 and SRI-6 response rates and flares. RESULTS In total, 253 patients entered the ADDRESS II LTE; 88 received atacicept 150 mg, 82 atacicept 75 mg and 83 placebo/atacicept 150 mg. Median active treatment duration in the LTE was 83.8 weeks. Frequencies of treatment-emergent adverse events (TEAEs) were similar across groups (90.4-93.2%), and 12.5%, 14.6% and 21.7% of patients in the atacicept 150 mg, atacicept 75 mg and placebo/atacicept 150 mg groups reported serious TEAEs during the treatment period. The proportions of patients with TEAEs leading to discontinuation were 5.7%, 4.9% and 10.8%, respectively. SRI-4 and SRI-6 response rates were maintained with atacicept in the modified intent-to-treat and HDA populations and those on continuous 150 mg had a reduced risk of first severe flare and longer time to first severe flare vs those who initially received placebo. CONCLUSION Long-term treatment with atacicept 150 mg in SLE patients had an acceptable safety profile, with durable efficacy.

Abstract
OBJECTIVE Similarities in the clinical and laboratory features of primary Sjögren's syndrome (SS) and systemic lupus erythematosus (SLE) have led to attempts to treat patients with primary SS or SLE with similar biologic therapeutics. However, the results of many clinical trials are disappointing, and no biologic treatments are licensed for use in primary SS, while only a few biologic agents are available to treat SLE patients whose disease has remained refractory to other treatments. With the aim of improving treatment selections, this study was undertaken to identify distinct immunologic signatures in patients with primary SS and patients with SLE, using a stratification approach based on immune cell endotypes. METHODS Immunophentyping of 29 immune cell subsets was performed using flow cytometry in peripheral blood from patients with primary SS (n = 45), patients with SLE (n = 29), and patients with secondary SS associated with SLE (SLE/SS) (n = 14), all of whom were considered to have low disease activity or be in clinical remission, and sex-matched healthy controls (n = 31). Data were analyzed using supervised machine learning (balanced random forest, sparse partial least squares discriminant analysis), logistic regression, and multiple t-tests. Patients were stratified by K-means clustering and clinical trajectory analysis. RESULTS Patients with primary SS and patients with SLE had a similar immunologic architecture despite having different clinical presentations and prognoses. Stratification of the combined primary SS, SLE, and SLE/SS patient cohorts by K-means cluster analysis revealed 2 endotypes, characterized by distinct immune cell profiles spanning the diagnoses. A signature of 8 T cell subsets that distinctly differentiated the 2 endotypes with high accuracy (area under the curve 0.9979) was identified in logistic regression and machine learning models. In clinical trajectory analyses, the change in damage scores and disease activity levels from baseline to 5 years differed between the 2 endotypes. CONCLUSION These findings identify an immune cell toolkit that may be useful for differentiating, with high accuracy, the immunologic profiles of patients with primary SS and patients with SLE as a way to achieve targeted therapeutic approaches.

Abstract
OBJECTIVES Risk factors for thromboembolism in SLE are poorly understood. We hypothesized a possible role for protein C, based on its dual activity in inflammation and haemostasis and on the evidence of an association between acquired activated protein C (APC) resistance (APCR) and high-avidity anti-protein C antibodies (anti-PC) with a severe thrombotic phenotype in venous thrombosis APS patients. METHODS In a cross-sectional study of 156 SLE patients, the presence and avidity of IgG anti-PC was established by in house-ELISA, and APCR to exogenous recombinant human APC (rhAPC) and Protac (which activates endogenous protein C) was assessed by thrombin generation-based assays. Associations with aPL profile, thrombotic history and disease activity (BILAG and SLEDAI-2K) were also established. RESULTS Anti-PC were detected in 54.5% of patients and APCR in 59%. Anti-PC positivity was associated with APCR to both rhAPC (P <0.0001) and Protac (P =0.0001). High-avidity anti-PC, detected in 26.3% of SLE patients, were associated with APCR in patients with thrombosis only (P <0.05), and with the development of thrombosis over time (range: 0-52 years; P =0.014). High-avidity anti-PC levels correlated with SLEDAI-2K (P =0.033) and total BILAG (P =0.019); SLEDAI-2K correlated inversely with APCR to Protac (P =0.004). CONCLUSION Anti-PC occur in patients with SLE, independently of aPL profile, and are associated with APCR. High-avidity anti-PC are associated with thrombosis and with active disease and might prove a novel marker to monitor the risk of thrombosis and disease progression in SLE.

Abstract
OBJECTIVES To characterize a LN cohort over 40 years, assessing its evolution, analysing two major outcomes: the development of end-stage renal disease and mortality rates in the first 5 years after LN diagnosis. METHODS An observational retrospective study of patients with LN, followed up from 1975 at University College Hospital. Patients were divided into four groups, depending on the decade of LN diagnosis: 1975-1985 (D1), 1986-1995 (D2), 1996-2005 (D3) and 2006-2015 (D4). Comparison between groups was performed with respect to demographic, clinical, serological and histological characteristics and outcome. RESULTS Two hundred and nineteen patients with LN were studied. There was a change in ethnic distribution, with a decreasing proportion of Caucasians (58.6% in D1 to 31.3% in D4, P = 0.018) and increase in African-ancestry (17.2% in D1 to 39.6% in D4, P = 0.040). Serological and histological patterns changed throughout time, with a reduction in class IV nephritis (51.7% in D1 to 27.1% in D4, P = 0.035), and increase in class II nephritis (10% in D2 to 18.8% in D4, P = 0.01) and anti-extractable nuclear antigen antibody positivity (17.2% in D1 to 83.3% in D4, P = 0.0001). The 5-year mortality rates decreased from D1 (24.1%) to D2 (4%), stabilizing for the next 30 years. The 5-year progression to end-stage renal disease remained stable over the decades. CONCLUSION Despite the changes in treatment of LN in the past 20 years, we have reached a plateau in 5-year mortality and progression to end-stage renal disease rates, suggesting that new therapeutic and management approaches, and strategies to enhance adherence, are needed to improve outcomes further in LN patients.

Abstract
OBJECTIVES To determine predictors for change in neuropsychiatric (NP) event status in a large, prospective, international, inception cohort of SLE patients METHODS: Upon enrollment and annually thereafter, NP events attributed to SLE and non-SLE causes and physician determined resolution were documented. Factors potentially associated with onset and resolution of NP events were determined by time-to-event analysis using a multistate modelling structure. RESULTS NP events occurred in 955/1,827 (52.3%) patients and 592/1910 (31.0%) unique events were attributed to SLE. For SLE NP events multivariate analysis revealed positive associations with male sex, concurrent non-SLE NP events excluding headache, active SLE and corticosteroids. There was a negative association with Asian race/ethnicity, post-secondary education, and immunosuppressive or anti-malarial drugs. For non-SLE NP events, excluding headache, there was a positive association with concurrent SLE NP events and negative associations with African and Asian race/ethnicity. NP events attributed to SLE had a higher resolution rate than non-SLE NP events, with the exception of headache that had comparable resolution rates. For SLE NP events, multivariate analysis revealed resolution was more common with Asian race/ethnicity and for central/focal NP events. For non-SLE NP events resolution was more common with African race/ethnicity and less common with older age at SLE diagnosis. CONCLUSIONS In a large and long-term study of the occurrence and resolution of NP events in SLE we identified subgroups with better and worse prognosis. The course of NP events differs greatly depending on their nature and attribution.

Abstract
Abstract
Background/Aims
BILAG-2004 index is required to prescribe and monitor biologics in SLE. It is more comprehensive and responsive than the SLEDAI and widely used in clinical trials. However, it may be time-consuming and does require training for accurate use. The original format requires a separate index form, glossary and scoring algorithm. Further, the eventual scores from A (highly active) to E (no disease involvement) which are required to make treatment decisions, can be difficult to calculate during in routine clinical practice.The Easy-BILAG project aimed to develop and validate a simplified tool to score the original BILAG-2004 index more rapidly and with fewer errors, for use in routine clinical care.
Methods
The BILAG group identified four areas to address: (i) many items must be scored, but most are rare; (ii) glossary definitions are not always followed; (iii) the final score is not easily calculated at the time of assessment; (iv) training is time-consuming. Data from the BILAG-Biologics Registry were used to measure the frequency of each of 97 BILAG-2004 items in an active SLE population. These data and a series of prototypes were used to design a new tool for simplified scoring of the BILAG-2004 index - the “Easy-BILAG”. This instrument content was tested using exemplar paper cases. A validation study was then designed to test the Easy-BILAG compared to the standard BILAG-2004 scoring method for completion time and accuracy.
Results
2395 assessments from the BILAG-BR were analysed. There was marked variation in item frequency. The 7 most frequent items were each present in more than 20% of records: arthralgia (72%), mild skin eruption (47%), moderate arthritis (38%), mild mucosal ulceration (34%), mild alopecia (34%), pleurisy / pericarditis (22%). 16 more items were scored in 5-20% of assessments; 36 items in 1-5% of assessments, and 25 items in < 1% of assessments. The Easy-BILAG was designed to capture items scoring >5% in a rapid single-page assessment. Items are arranged in a logical sequence of clinical assessment. An abridged glossary definition is cited immediately adjacent to each item. A new colour-coding system directs clinicians instantly to the overall A-E score for each domain (colour-blindness compatible). This single page assessment covered 68% of all assessments of biologic-treated patients. The remaining items are scored on a back page only in cases where necessary, as indicated by screening questions on the main page. The overall accuracy and usability of the Easy-BILAG template is now undergoing a validation against test series of standardized case vignettes by a sample of consultants and specialty trainees with a range of experience across England and Wales.
Conclusion
Easy-BILAG allows rapid scoring of BILAG-2004 in routine clinical practice. Following completion of validation, it will be made widely available to clinicians.

Abstract
OBJECTIVE To compare the responsiveness of BILAG-2004 and SLEDAI-2000 disease activity indices and determine if there was any added value in combining BILAG-2004, BILAG System Tally (BST) or simplified BST (sBST) with SLEDAI-2000. METHODS This was a multi-centre longitudinal study of SLE patients. Data were collected on BILAG-2004, SLEDAI-2000 and therapy on consecutive assessments in routine practice. The external responsiveness of the indices was assessed by determining the relationship between change in disease activity and change in therapy between two consecutive visits. Comparison of indices and their derivatives was performed by assessing the main effects of the indices using logistic regression. ROC curves analysis was used to describe the performance of these indices individually and in various combinations and comparisons of AUC were performed. RESULTS There were 1414 observations from 347 patients. Both BILAG-2004 and SLEDAI-2000 maintained an independent relationship with change in therapy when compared. There was some improvement in responsiveness when continuous SLEDAI-2000 variables (change in score and score of previous visit) were combined with BILAG-2004 system scores. Dichotomisation of BILAG-2004 or SLEDAI-2000 resulted in poorer performance. BST and sBST had similar responsiveness as the combination of SLEDAI-2000 variables and BILAG-2004 system scores. There was little benefit in combining SLEDAI-2000 with BST or sBST. CONCLUSIONS The BILAG-2004 index had comparable responsiveness to SLEDAI-2000. There was some benefit in combining both indices. Dichotomisation of BILAG-2004 and SLEDAI-2000 leads to suboptimal performance. BST and sBST performed well on their own; sBST is recommended for its simplicity and clinical meaningfulness.

Abstract
BACKGROUND Cardiovascular disease is a leading cause of mortality in patients with juvenile-onset systemic lupus erythematosus (JSLE). Traditional factors for cardiovascular risk (CVR) prediction are less robust in younger patients. More reliable CVR biomarkers are needed for JSLE patient stratification and to identify therapeutic approaches to reduce cardiovascular morbidity and mortality in JSLE. METHODS Serum metabolomic analysis (including >200 lipoprotein measures) was performed on a discovery (n=31, median age 19) and validation (n=31, median age 19) cohort of JSLE patients. Data was analysed using cluster, receiver operating characteristic analysis and logistic regression. RNA-sequencing assessed gene expression in matched patient samples. FINDINGS Hierarchical clustering of lipoprotein measures identified and validated two unique JSLE groups. Group-1 had an atherogenic and Group-2 had an atheroprotective lipoprotien profile. Apolipoprotein(Apo)B:ApoA1 distinguished the two groups with high specificity (96.2%) and sensitivity (96.7%). JSLE patients with high ApoB:ApoA1 ratio had increased CD8+ T-cell frequencies and a CD8+ T-cell transcriptomic profile enriched in genes associated with atherogenic processes including interferon signaling. These metabolic and immune signatures overlapped statistically significantly with lipid biomarkers associated with sub-clinical atherosclerosis in adult SLE patients and with genes overexpressed in T-cells from human atherosclerotic plaque respectively. Finally, baseline ApoB:ApoA1 ratio correlated positively with SLE disease activity index (r=0.43, p=0.0009) and negatively with Lupus Low Disease Activity State (r=-0.43, p=0.0009) over 5-year follow-up. INTERPRETATION Multi-omic analysis identified high ApoB:ApoA1 as a potential biomarker of increased cardiometabolic risk and worse clinical outcomes in JSLE. ApoB:ApoA1 could help identify patients that require increased disease monitoring, lipid modification or lifestyle changes.

Abstract
Objectives SLE is a severe autoimmune disease characterized by autoreactive B cells and IC formation, which causes systemic inflammation. B cell–targeted therapy could be a promising treatment strategy in SLE patients; nevertheless, randomized clinical trials have not always been successful. However, some groups have demonstrated beneficial effects in severe SLE patients with off-label rituximab (RTX) with belimumab (BLM), or bortezomib (BTZ), which targeted different B cells subsets. This study assembled sera from SLE cohorts treated with RTX+BLM (n = 15), BTZ (n = 11) and RTX (n = 16) to get an in-depth insight into the immunological effects of these therapies on autoantibodies and IC formation. Methods Autoantibodies relevant for IC formation and the avidity of anti-dsDNA were determined by ELISA. IC-mediated inflammation was studied by complement levels and ex vivo serum-induced neutrophil extracellular trap formation. Results Reductions in autoantibodies were observed after all approaches, but the spectrum differed depending upon the treatment. Specifically, only RTX+BLM significantly decreased anti-C1q. Achieving seronegativity of ≥1 autoantibody, specifically anti-C1q, was associated with lower disease activity. In all SLE patients, the majority of anti-dsDNA autoantibodies had low avidity. RTX+BLM significantly reduced low-, medium- and high-avidity anti-dsDNA, while RTX and BTZ only significantly reduced medium avidity. IC-mediated inflammation, measured by C3 levels and neutrophil extracellular trap formation, improved after RTX+BLM and RTX but less after BTZ. Conclusion This study demonstrated the impact of different B cell–targeted strategies on autoantibodies and IC formation and their potential clinical relevance in SLE.

Abstract
Objectives To compare membranous lupus nephritis (MLN) and proliferative lupus nephritis (PLN) with respect to survival, demographic, clinical and laboratory characteristics; and to investigate predictors of renal and patient survival. Methods Single-centre retrospective observational study. Patients with biopsy-proven PLN, MLN and mixed lupus nephritis were included. Groups were compared using appropriate statistical tests and survival was analysed through the Kaplan-Meier method. Cox regression analysis was performed to investigate predictors of renal and patient survival. Results A total of 187 patients with biopsy-proven lupus nephritis (135 with PLN, 38 with MLN and 14 with mixed LN) were followed for up to 42 years (median 12 years). There was a higher proportion of MLN amongst Afro-Caribbeans than amongst Caucasians (31% vs 15%, P = 0.010). Patients with MLN had significantly lower anti-dsDNA antibodies (P = 0.001) and higher C3 levels (P = 0.018) at diagnosis. Cumulative renal survival rates at 5, 10, 15 and 20 years were 91, 81, 75 and 66% for PLN and 100, 97, 92 and 84% for MLN, respectively (P = 0.028). Cumulative patient survival at 5, 10, 15 and 20 years was 94, 86, 80 and 76%, with no difference between PLN and MLN. Urinary protein-creatinine ratio above 42 mg/mmol and eGFR below 76 ml/min/1.73 m2, one year after the diagnosis of LN, were the strongest predictors of progression to end-stage renal disease. eGFR below 77 ml/min/1.73 m2, at one year, development of end-stage renal disease and Afro-Caribbean ethnicity were associated with higher mortality. Conclusion Patients with MLN and PLN differ significantly regarding serological profiles and renal survival, suggesting different pathogenesis. Renal function at year one predicts renal and patient survival.

Abstract
It is now two decades since Rituximab was first used in the treatment of patients with systemic lupus erythematosus. There have been many challenges but in spite of failing to meet its primary endpoints in two clinical trials it is widely used for many aspects of lupus, its side-effects and the possibility that combining it with Benlysta may be of value. We also consider the proposal that it may provide a useful initial therapy. In this review, we consider the place of Rituximab in the treatment of lupus and anticipate how developments in fully-humanized anti-CD20 monoclonals may well extend the "therapeutic life" of B-cell depletion as a viable treatment option.

Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is an autoimmune rheumatic disease characterized by multiple pathologies in which sustained inflammatory activity leads to progressive tissue destruction and organ damage. One of the main proinflammatory cytokines playing a key role in autoimmune diseases such as rheumatoid arthritis (RA) or SLE, is tumor necrosis factor (TNF) alpha. AREAS COVERED The introduction of TNF-alpha inhibitors revolutionized the treatment of RA and other conditions including psoriatic arthritis and ankylosing spodylitis. We review here the efficacy and safety of TNF-alpha blockers in SLE focussing on why it has not been more widely used since TNF-alpha was reported to be increased in SLE patients and to correlate with disease activity. EXPERT OPINION We summarize the reported SLE cases that have received TNF-alpha blockers and the main results to date. We reflect on whether there is a case to reconsider the use of TNF-alpha blockade in SLE.

Abstract
OBJECTIVES Patients with SLE have an increased risk of developing cardiovascular disease (CVD). Multiple studies have shown that these patients have increased numbers of carotid plaques and greater intima-media thickness (IMT) than healthy controls. Measures such as total plaque area (TPA) and plaque echogenicity may be more sensitive and more relevant to cardiovascular risk than presence of plaque and IMT alone. Our objective was to produce the first report of TPA and echogenicity in a population of patients with SLE. METHODS One hundred patients with SLE and no history of clinical CVD were recruited. Clinical, serological and treatment variables were recorded and serum was tested for antibodies to apolipoprotein A-1 and high-density lipoprotein. Both carotid and both femoral artery bifurcations of each patient were scanned to determine IMT, TPA and echogenicity of plaques. Univariable and multivariable statistical analyses were carried out to define factors associated with each of these outcomes. RESULTS Thirty-six patients had carotid and/or femoral plaque. Increasing age was associated with presence of plaque and increased IMT. Triglyceride levels were associated with presence of plaque. Mean (s.d.) TPA was 60.8 (41.6) mm2. Patients taking prednisolone had higher TPA. Most plaques were echolucent, but increased echogenicity was associated with prednisolone therapy and persistent disease activity. CONCLUSION TPA and plaque echogenicity in patients with SLE are associated with different factors than those associated with presence of plaque and IMT. Longitudinal studies may show whether these outcome measures add value in the management of cardiovascular risk in SLE.

Abstract
OBJECTIVE There is a paucity of data regarding health care costs associated with damage accrual in systemic lupus erythematosus. The present study was undertaken to describe costs associated with damage states across the disease course using multistate modeling. METHODS Patients from 33 centers in 11 countries were enrolled in the Systemic Lupus International Collaborating Clinics (SLICC) inception cohort within 15 months of diagnosis. Annual data on demographics, disease activity, damage (SLICC/American College of Rheumatology Damage Index [SDI]), hospitalizations, medications, dialysis, and selected procedures were collected. Ten-year cumulative costs (Canadian dollars) were estimated by multiplying annual costs associated with each SDI state by the expected state duration using a multistate model. RESULTS A total of 1,687 patients participated; 88.7% were female, 49.0% were white, mean ± SD age at diagnosis was 34.6 ± 13.3 years, and mean time to follow-up was 8.9 years (range 0.6-18.5 years). Mean annual costs were higher for those with higher SDI scores as follows: $22,006 (Canadian) (95% confidence interval [95% CI] $16,662, $27,350) for SDI scores ≥5 versus $1,833 (95% CI $1,134, $2,532) for SDI scores of 0. Similarly, 10-year cumulative costs were higher for those with higher SDI scores at the beginning of the 10-year interval as follows: $189,073 (Canadian) (95% CI $142,318, $235,827) for SDI scores ≥5 versus $21,713 (95% CI $13,639, $29,788) for SDI scores of 0. CONCLUSION Patients with the highest SDI scores incur 10-year cumulative costs that are ~9-fold higher than those with the lowest SDI scores. By estimating the damage trajectory and incorporating annual costs, data on damage can be used to estimate future costs, which is critical knowledge for evaluating the cost-effectiveness of novel therapies.

Abstract
OBJECTIVE The Systemic Lupus International Collaborating Clinics (SLICC) frailty index (FI) predicts mortality and damage accrual in SLE, but its association with hospitalizations has not been described. We estimated the association of baseline SLICC-FI values with future hospitalizations in the SLICC inception cohort. METHODS Baseline SLICC-FI scores were calculated. The number and duration of inpatient hospitalizations during follow-up were recorded. Negative binomial regression was used to estimate the association between baseline SLICC-FI values and the rate of hospitalizations per patient-year of follow-up. Linear regression was used to estimate the association of baseline SLICC-FI scores with the proportion of follow-up time spent in hospital. Multivariable models were adjusted for relevant baseline characteristics. RESULTS The 1549 SLE patients eligible for this analysis were mostly female (88.7%) with mean (SD) age 35.7 (13.3) years and median (IQR) disease duration 1.2 (0.9-1.5) years at baseline. Mean (SD) baseline SLICC-FI was 0.17 (0.08). During mean (SD) follow-up of 7.2 (3.7) years, 614 patients (39.6%) experienced 1570 hospitalizations. Higher baseline SLICC-FI values (per 0.05 increment) were associated with more frequent hospitalizations during follow-up (Incidence Rate Ratio 1.21; 95%CI 1.13-1.30), adjusting for baseline age, sex, corticosteroid use, immunosuppressive use, ethnicity/location, SLE disease activity index 2000 (SLEDAI-2K), SLICC/ACR damage index (SDI), and disease duration. Among patients with ≥1 hospitalization, higher baseline SLICC-FI values predicted a greater proportion of follow-up time spent hospitalized (Relative Rate 1.09; 95%CI 1.02-1.16). CONCLUSION The SLICC-FI predicts future hospitalizations among incident SLE patients, further supporting the SLICC-FI as a valid health measure in SLE.

Abstract
The emergence of COVID-19 in early 2020 led to unprecedented changes to rheumatology clinical practice worldwide, including the closure of research laboratories, the restructuring of hospitals and the rapid transition to virtual care. As governments sought to slow and contain the spread of the disease, rheumatologists were presented with the difficult task of managing risks, to their patients as well as to themselves, while learning and implementing new systems for remote health care. Consequently, the COVID-19 pandemic led to a transformation in health infrastructures and telemedicine that could become powerful tools for rheumatologists, despite having some limitations. In this Viewpoint, five experts from different regions discuss their experiences of the pandemic, including the most challenging aspects of this unexpected transition, the advantages and limitations of virtual visits, and potential opportunities going forward. The COVID-19 pandemic led to unprecedented changes in rheumatology clinical practice. In this Viewpoint article, we asked five experts to describe their experiences of the COVID-19 pandemic, how their clinical practice has changed, and the opportunities and challenges that lie ahead. Eloisa Bonfá is a full professor of rheumatology and the clinical director of the largest tertiary public hospital of Latin America. Her main clinical and research interests are systemic lupus erythematosus and autoimmunity, with relevant contributions in the fields of autoantibodies, vaccines and drug monitoring in autoimmune diseases. She graduated at the University of São Paulo Medical School, Brazil, and undertook specialist training in rheumatology in the same university followed by a 4-year rheumatology research fellowship at the Hospital for Special Surgery, New York. Laure Gossec is a professor of rheumatology at Sorbonne Université and Pitié-Salpêtrière Hospital, Paris, France. She has a half-time clinical position where she mainly sees patients with inflammatory arthritis, and a half-time teaching and research position. Her main research interests are patient-reported outcomes and quality of life, as well as e-health and big data in psoriatic arthritis, spondyloarthritis and rheumatoid arthritis and she has authored more than 350 papers. She is a past-chair of the epidemiology standing committee of EULAR. David Isenberg is the Academic Director of Rheumatology at University College London, UK. He has run both general and autoimmune rheumatic disease clinics for over 30 years. His major research interests are in the structure, function and origin of autoantibodies and improving the assessment of patients with autoimmune rheumatic diseases. Zhanguo Li is a professor and head of the department of rheumatology and immunology at the Peking University People’s Hospital, China. He is the past president of APLAR, and the president of the Clinical Immunology Committee at the Chinese Society for Immunology. He is Editor-in-Chief of the Chinese Journal of Rheumatology. His research interests are the mechanisms and immune therapy of rheumatic diseases, including rheumatoid arthritis and systemic lupus erythematosus. Soumya Raychaudhuri is a Professor at Harvard Medical School, and a practicing rheumatologist at the Brigham and Women’s Hospital Arthritis Center. He is also appointed at the Broad Institute, and the University of Manchester. He spends most of his time running a lab that is focused on defining mechanisms of disease in rheumatoid arthritis, and other immune-mediated diseases, using computational biology, genetics and functional genomics.

Abstract
The antiphospholipid antibody syndrome (APS), a chronic autoimmune thrombophilia with an increased mortality and morbidity, has been recognized for more than three decades. Unlike other autoimmune rheumatic conditions such as systemic lupus erythematosus, myositis and Sjögren's syndrome, relatively few attempts have been made to develop activity, damage or disease-specific quality of life indices for APS. In this review of the literature, we consider those attempts that have been made to develop assessment tools for patients with APS, but also reflect upon the nature of the condition, to discuss, in particular, whether an activity index is appropriate for this disease.

Abstract
Antiphospholipid syndrome (APS), an acquired autoimmune thrombophilia, is characterised by thrombosis and/or pregnancy morbidity in association with persistent antiphospholipid antibodies. The 16th International Congress on Antiphospholipid Antibodies Task Force on APS Treatment Trends reviewed the current status with regard to existing and novel treatment trends for APS, which is the focus of this Task Force report. The report addresses current treatments and developments since the last report, on the use of direct oral anticoagulants in patients with APS, antiplatelet agents, adjunctive therapies (hydroxychloroquine, statins and vitamin D), targeted treatment including rituximab, belimumab, and anti-TNF agents, complement inhibition and drugs based on peptides of beta-2-glycoprotein I. In addition, the report summarises potential new players, including coenzyme Q10, adenosine receptor agonists and adenosine potentiation. In each case, the report provides recommendations for clinicians, based on the current state of the art, and suggests a clinical research agenda. The initiation and development of appropriate clinical studies requires a focus on devising suitable outcome measures, including a disease activity index, an optimal damage index, and a specific quality of life index.
