Objectives The lupus low disease activity state (LLDAS) allows for certain clinical and/or serological activity of SLE, provided overall disease activity does not exceed predefined cut-offs. This study aimed to evaluate the outcomes of patients who achieved LLDAS with clinical activity, serological activity only or neither clinical nor serological activity.Methods Patients with SLE enrolled in a prospective multinational cohort from March 2013 to December 2020 who were in LLDAS at least once were included. Visits that fulfilled both LLDAS and Definition of Remission in SLE (DORIS) criteria were excluded.Results 2099 patients were included, with median follow-up of 3.5 (IQR 1.3–5.8) years. At 6150 visits, patients were in LLDAS but not DORIS criteria; of these 1280 (20.8%) had some clinical activity, 3102 (50.4%) visits had serological activity only and 1768 (28.8%) visits had neither clinical nor serological activity. Multivariable regression analysis showed that compared with non-LLDAS, all three subsets of LLDAS had a protective association with flares in the ensuing 6 months and damage accrual in the ensuing 36 months. LLDAS with no clinical or serological activity had a significantly stronger protective association with severe flares in the ensuing 6 months compared with LLDAS with clinical activity (HR 0.47, 95% CI (0.27 to 0.82), p=0.007).Conclusions LLDAS without any clinical activity accounted for almost 80% of LLDAS visits. This study confirms that all subsets of LLDAS are associated with reduced flare and damage accrual. However, LLDAS without any clinical or serological activity has the strongest protective association with severe flares.

Objectives To evaluate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine acceptance among patients with rheumatic diseases (RMD). Methods All rheumatology patients attending a large suburban health network were invited to participate in an anonymized online survey. The primary outcome of interest was SARS-COV-2 vaccine acceptance. Results The mean (SD) age of respondents (n = 641) was 52.7 (15.1) years and 74.4% (n = 474) were female. Sixty-five percent were willing to have a SARS-COV-2 vaccine, while 34.4% were vaccine-hesitant (unwilling or undecided). On multivariate analysis, vaccine acceptance was associated with smoking (OR: 2.25 [95% CI: 1.22–4.15; p = .009]), history of malignancy (OR: 2.51 [95% CI: 1.19–5.26; p = .015]), influenza or pneumococcal vaccination in the preceding year (OR: 2.69 [95% CI: 1.78–4.05; p

Objectives Type 1 interferon (IFN) is key to the pathogenesis of SLE, evidenced by the expression of IFN-stimulated genes (ISGs) in most patients, but the clinical utility of serial ISG assessment remains unknown. With the emergence of IFN-blocking drugs, we aimed to examine IFN status in relation to clinical findings longitudinally to provide insights into the value of testing ISG levels over time.Methods Clinical data and whole blood were collected prospectively on adult patients with SLE from a single tertiary lupus centre. IFN status was measured using a panel of ISGs.Findings 729 samples were analysed from 205 patients. At baseline, 62.9% of patients were IFN high, 30.2% IFN low and 6.8% borderline. 142 patients had multiple samples collected, and 87.3% of these demonstrated stable ISG status over time. In longitudinal follow-up, IFN high patients had higher activity in multiple organ domains and spent less time in Lupus Low Disease Activity State, but IFN score did not correlate with SLE Disease Activity Index in individual patients. In the small subset of patients who had large fluctuations in ISG across the observation period, most had high-dose glucocorticoids that correlated with ISG suppression. However, low-moderate-dose glucocorticoids did not suppress ISG expression.Conclusion Although IFN high status is associated with indicators of more severe SLE, in the majority of patients, ISGs are stable across time and do not correlate with disease activity. Changes in ISG expression may be seen with high-dose, but not routine dose, glucocorticoid exposure. These findings suggest baseline but not serial ISG measurement may be of value in the management of SLE.

Objective In systemic lupus erythematosus (SLE), disease activity and glucocorticoid (GC) exposure are known to contribute to irreversible organ damage. We aimed to examine the association between GC exposure and organ damage occurrence.Methods We conducted a literature search (PubMed (Medline), Embase and Cochrane January 1966–October 2021). We identified original longitudinal observational studies reporting GC exposure as the proportion of users and/or GC use with dose information as well as the occurrence of new major organ damage as defined in the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index. Meta-regression analyses were performed. Reviews, case-reports and studies with

Despite promising candidates for new therapeutic options in the treatment of systemic lupus erythematosus (SLE), many clinical trials have failed in the past few years. The disappointing results have been at least partly be attributed to trial designs. With the aim of stimulating new developments in SLE trial design, an international open space meeting was held on occasion of the European Lupus Meeting 2018 in Duesseldorf, Germany about ‘What are the topics you care about for making trials in lupus more effective?’. The Open Space is a participant-driven technology, where the discussion topics and schedule are selected during the meeting by all participants and discussion rounds are led by the people attending encouraging active contributions. Eleven topics were selected for further discussion, of which 6 were voted to be more intensively discussed in two consecutive rounds. Major topics were the optimal handling of glucocorticoids in clinical trials, the improvement of outcome measures, reducing or controlling the placebo response and the identification of biomarkers and stratification parameters. Further, the importance of local and international networks was emphasised. By networking, collaborations are facilitated, patient recruitment is more efficient and treatment can be harmonised thus lead to more successful SLE trials. Further discussions are needed to substantiate the results and develop new trial designs.

Objective Disease severity in SLE is an important concept related to disease activity, treatment burden and prognosis. We set out to evaluate if high disease activity status (HDAS), based on ever attainment of a Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) disease activity score of ≥10, is an indicator for disease severity in SLE.Methods Using prospectively collected data, we assessed the association of HDAS with sociodemographic and disease characteristics and adverse clinical outcomes using logistic regression or generalised estimating equations.Results Of 286 patients with SLE, who were observed for a median (range) of 5.1 years (1–10.8 years), 43.7% experienced HDAS at least once during the observational period. Autoantibody positivity, particularly anti-dsDNA and anti-Sm positivity, were associated with increased likelihood of HDAS. Age ≥45 years at diagnosis was associated with reduced likelihood of HDAS (p=0.002). Patients with HDAS had higher Physician Global Assessment score (>1: OR 8.1, p0.001), higher corticosteroid exposure (corticosteroid dose in highest quartile: OR 7.7, 95% CI 3.9 to 15.3; p

Objectives To characterise the prevalence and associations of metabolic syndrome (MetS) in a multiethnic cohort of patients with SLE.Methods Using a standardised protocol, baseline demographics, per visit disease activity (Systemic Lupus Erythematosus Disease Activity Index-2K) and treatment data, and annual recording of organ damage accrual (Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC-ACR) Damage Index) were captured on patients with SLE from a single tertiary centre. The presence of MetS, defined using modified updated joint consensus criteria, was assessed at the final visit from patient records. Serum concentrations of adipocytokines were measured by Quantibody.Results 116 patients, with median (Q1, Q3) age at enrolment of 39.5 (31.4–51.1) years and disease duration of 6.1 (1.4–12) years, were followed for a median of 6.7 (4.1–8.1) years. The prevalence of MetS was 29% (34/116), while the prevalence of MetS components varied: hypertension (59%), low high-density lipoproteins (HDLs) (51%), hypertriglyceridaemia (32%), obesity (16%) and hyperglycaemia (22%). In univariable analysis, MetS was associated with baseline organ damage (OR 4.34; 95% CI 1.80 to 10.48; p

Abstract Objectives Plasmacytoid dendritic cells (pDCs), through the production of type 1 interferons (IFNs) and other cytokines, are major contributors to systemic lupus erythematosus (SLE) pathogenesis. IL‐3 promotes pDC survival, but its role in SLE is not well characterised. This study investigated serum IL‐3 and IFN levels, and a whole blood ‘IL‐3 gene signature’, in human SLE. Methods Serum cytokine levels were measured by ELISA in n = 42 SLE patients, and n = 44 healthy donors. IL‐3‐regulated genes were determined by RNASeq of healthy donor whole blood cells (WBCs) stimulated in vitro with IL‐3 for 6 or 24 h. Whole blood cell RNASeq analysis was undertaken in a separate cohort of n = 31 SLE patients, and n = 28 healthy donors. Results Serum IL‐3 levels correlated with IFNα (r = 0.612, 95% CI 0.455–0.733, P
