Objective: To assess treatment patterns and the association between long-term glucocorticoid (GC) and hydroxychloroquine (HCQ) use and damage accrual in patients with systemic lupus erythematosus (SLE).
Methods: A retrospective study including patients with SLE using the computerised database of a large health maintenance organisation. Patients were matched with subjects from the general population. Multivariable logistic regression models were used to assess the association between GC cumulative daily doses, HCQ and comorbidities: Osteoporosis, cardiovascular disease (CVD), hypertension and diabetes mellitus. Models were adjusted for age, sex, socioeconomic status, smoking, disease duration and HCQ use.
Results: A total of 1073 patients with SLE were included, 87.79% were women. The age at first diagnosis was 37.23±14.36 and the SLE disease duration was 12.89±6.23 years. Initiation of HCQ within 12 months of SLE diagnosis increased from 51.02% in 2000 to 83.67% in 2010 and 93.02% in 2018. The annual usage of GC gradually decreased from 45.34% in 2000 to 30.76% in 2020. CVD and osteoporosis were more prevalent in SLE than in the general population. Multivariable logistic regression models revealed increased odds for comorbidities in patients receiving a mean daily dose of prednisone of more than 5 mg/day compared with those receiving 5 mg/day or less.
Conclusions: CVD and osteoporosis were more prevalent in SLE than in the general population. The dose and frequency of GC treatment in patients with SLE have decreased over the years. Prednisone usage in doses exceeding 5 mg/day is associated with significantly increased odds of osteoporosis and CVD.

Objectives: To measure the expression level of the vacuolar protein sorting 13 (VPS13) gene and stimulator of interferon genes (STING) in patients with SLE with and without reported neuropsychiatric symptoms to establish their possible role in the pathogenesis of neuropsychiatric SLE (NPSLE).
Methods: This study included 100 subjects: 50 patients diagnosed with SLE and 50 age-matched and sex-matched healthy participants as the control group. The patients with SLE were further subdivided into NPSLE and non-NPSLE groups. All the subjects underwent rheumatological, neurological and psychological evaluation, MRI, VPS13C gene and STING expression assessment via quantitative real-time PCR.
Results: Seventy-eight per cent of the SLE group were classified as non-NPSLE, and 22% were classified as NPSLE. Positive MRI results were found in 55% of the patients with NPSLE and 7.7% of the patients without NPSLE.VPS13C expression levels were decreased in the patients with SLE compared with the control (p<0.001), while STING expression levels showed higher levels in the patients in comparison with the control (p<0.001). Both markers showed significant differences between the MRI-positive and MRI-negative groups.At a cut-off value of 0.225 for the VPS13C assessment and a cut-off value of 3.15 for STING expression, both markers were able to distinguish patients with NPSLE from those who were non-NPSLE; however, VPS13C performed better.
Conclusion: The VPS13C expression levels were decreased in patients with NPSLE compared with patients without NPSLE, while STING expression levels showed higher levels in NPSLE. Both were associated with the MRI findings. To distinguish patients with NPSLE from those without it, the VPS13C assessment performed better.

Objective: To evaluate both humoral and cellular immune responses to the COVID-19 messenger RNA (mRNA; BNT162b2) vaccine in patients with childhood-onset SLE (cSLE) compared with healthy controls and patient controls (kidney transplant (KTx) recipients).
Methods: This single-centre, cross-sectional and case-control study included 16 patients with cSLE, 19 healthy controls and 19 KTx recipients. We assessed SARS-CoV-2-specific humoral (anti-SARS-CoV-2 IgG, neutralising antibody (nAb)) and cellular (interferon gamma release assay (IGRA)) immune responses at least 1 month after administration of two doses of the mRNA vaccine.
Results: Humoral immune response rates (anti-SARS-CoV-2 IgG and nAb seropositivity) in patients with cSLE were comparable to healthy controls (100% vs 100% and 100% vs 95%, respectively) but significantly higher than in KTx recipients (74% and 42%, p<0.05 for both). Cellular immune response rate measured by IGRA was lower in patients with cSLE compared with healthy controls (56.3% vs 89.5%, p=0.050) and comparable to KTx recipients (63%). IGRA-negative patients with cSLE had significantly lower total leucocyte and lymphocyte counts at vaccination time as compared with their counterparts (p=0.008 and p=0.001, respectively). No differences were found in disease activity or immunosuppressive therapies between IGRA-negative and IGRA-positive patients with cSLE.
Conclusion: Patients with cSLE showed robust humoral but compromised cellular immune responses to the COVID-19 mRNA vaccine, associated with lower lymphocyte counts. These findings highlight the need for further research to enhance vaccine efficacy in this vulnerable group.

Objectives: In childhood-onset SLE (cSLE), patients have an increased risk of premature atherosclerosis. The pathophysiological mechanisms for this premature atherosclerosis are not yet completely understood, but besides traditional risk factors, the endothelium plays a major role. The first aim of this study was to measure levels of SLE-associated markers involved in endothelial cell (EC) function and lipids in a cSLE cohort longitudinally in comparison with healthy controls (HC). Next aim was to correlate these levels with Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and nailfold capillaroscopic patterns.
Methods: Blood serum samples, videocapillaroscopy images and patient characteristics were collected in a multicentre longitudinal cSLE cohort and from age and sex comparable HC. Disease activity was evaluated by SLEDAI. A total of 15 EC markers and six lipids were measured in two longitudinal cSLE samples (minimum interval of 6 months) and in HC. Nailfold videocapillaroscopy images were scored according to the guidelines from the EULAR Study Group on Microcirculation in Rheumatic Diseases.
Results: In total, 47 patients with cSLE and 42 HCs were analysed. Median age at diagnosis was 15 years (IQR 12-16 years). Median time between t=1 and t=2 was 14.5 months (IQR 9-24 months). Median SLEDAI was 12 (IQR 6-18) at t=1 and 2 (IQR 1-4) at t=2. Serum levels of angiopoietin-2, CCL2, CXCL10, GAS6, pentraxin-3, thrombomodulin, VCAM-1 and vWF-A2 were elevated in cSLE compared with HC at t=1. While many elevated EC markers at t=1 normalised over time after treatment, several markers remained significantly increased compared with HC (angiopoietin-2, CCL2, CXCL10, GAS6, thrombomodulin and VCAM-1).
Conclusion: In serum from patients with cSLE different markers of endothelial activation were dysregulated. While most markers normalised during treatment, others remained elevated in a subset of patients, even during low disease activity. These results suggest a role for the dysregulated endothelium in early and later phases of cSLE, possibly also during lower disease activity.

Background Rituximab is associated with high infection rates, but studies of infections following rituximab in youth with childhood-onset SLE (cSLE) are limited. We conducted a retrospective longitudinal cohort study to assess the incidence of hospitalised infections following rituximab among children with cSLE and to assess changes in hospital-based rituximab administration over time. Methods Youth ages 2–21 years with an International Classification of Diseases (ICD) code for SLE who received rituximab during admission to a Pediatric Health Information System hospital from 2009 to 2021 were included. Incidence rates for infections requiring hospitalisation over the 12 months following first rituximab administration were calculated. Rituximab use by year of hospital discharge was tabulated. Results We identified 1567 children with cSLE who received rituximab. 219 children were admitted with an infection within 1 year after first rituximab administration, for an incidence rate of 140 cases per 1000 patient-years. Seven children (0.44%) died during a hospitalisation with an infection in the year following rituximab administration. The most common hospitalised infections were bacterial pneumonia, sepsis and cellulitis. 12 children were hospitalised with COVID-19, none of whom died. Hospitalisations with rituximab administered decreased from 2019 to 2021. Conclusions In this cohort of patients with cSLE who received inpatient treatment with rituximab, we observed a 14% rate of hospitalisation with infection in the year following rituximab administration among youth with cSLE. Rituximab use declined during the COVID-19 pandemic. No fatalities with COVID-19 were observed. Given the lack of outpatient data, including doses of concomitant medications and disease activity measures, further research is needed to identify risk factors for infection following rituximab among children with cSLE. Data are available upon reasonable request. Deidentified data may be provided upon request pending approval of the Seattle Children’s Hospital IRB and the Children’s Hospital Association.

Purpose This study investigated the topological structural characteristics of systemic lupus erythematosus (SLE) with and without neuropsychiatric symptoms (NPSLE and non-NPSLE), and explore their clinical implications. Methods We prospectively recruited 50 patients with SLE (21 non-NPSLE and 29 NPSLE) and 32 age-matched healthy controls (HCs), using MRI diffusion tensor imaging. Individual structural networks were constructed using fibre numbers between brain areas as edge weights. Global metrics (eg, small-worldness, global efficiency) and local network properties (eg, degree centrality, nodal efficiency) were computed. Group comparisons of network characteristics were conducted. Clinical correlations were assessed using partial correlation, and differentiation between non-NPSLE and NPSLE was performed using support vector classification. Results Patients with oth non-NPSLE and NPSLE exhibited significant global and local topological alterations compared with HCs. These changes were more pronounced in NPSLE, particularly affecting the default mode and sensorimotor networks. Topological changes in patients with SLE correlated with lesion burdens and clinical parameters such as disease duration and the systemic lupus international collaborating clinics damage index. The identified topological features enabled accurate differentiation between non-NPSLE and NPSLE with 87% accuracy. Conclusion Structural networks in patients SLE may be altered at both global and local levels, with more pronounced changes observed in NPSLE, notably affecting the default mode and sensorimotor networks. These alterations show promise as biomarkers for clinical diagnosis. Data are available upon reasonable request.

The identified topological features enabled accurate differentiation between non-NPSLE and NPSLE with 87% accuracy. Conclusion Structural networks in patients SLE may be altered at both global and local levels, with more pronounced changes observed in NPSLE, notably affecting the default mode and sensorimotor networks. These alterations show promise as biomarkers for clinical diagnosis.

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. Data are available on reasonable request. Access to APLC pooled data is subject to the specific guidelines outlined in the APLC data access policy (available on request to the APLC steering committee).

Objectives: Rheumatic diseases were previously associated with increased incidence of monoclonal gammopathy (MG) and its malignant transformation. The present study aimed to investigate the prevalence, malignant transformation risk, clinical correlates and prognostic impact of MG in SLE.
Methods: A retrospective cohort study based on the medical records of n=1039 patients with SLE fulfilling the 1997 American College of Rheumatology (ACR), the 2019 European Alliance of Associations for Rheumatology (EULAR)/ACR and/or the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria managed at two tertiary care departments of the University Hospital (Krakow, Poland) from January 2012 until November 2019.
Results: SLE+MG cases were older at SLE diagnosis compared with non-MG SLE controls (53±15 years vs 37±15 years, respectively, p<0.01), had higher rates of lymphopenia, anaemia, haemolysis, serous effusions and interstitial lung disease (all p<0.05), and were more frequently treated with cyclophosphamide (57% vs 28%, p<0.01) or rituximab (13% vs 3%, p<0.01). Most MG cases were detected within a year after SLE diagnosis (Q25, Q75: 0, 12 years). With the median follow-up of 11 years (Q25, Q75: 6, 19 years), 34.8% (8 cases) of the SLE+MG cohort were diagnosed with malignancy, compared with 8.1% (82 cases) among the SLE controls (p<0.001). MG was associated with the relative hazard of death of HR 2.99 (95% CI 1.26 to 7.06, p<0.05) and a median survival time from SLE diagnosis to death of 5 years (Q25, Q75: 1, 14; range 0-41) for SLE+MG cases, as compared with 12 years (Q25, Q75: 6, 19; range 0-62) for the controls. The effect was non-independent on antimalarial medication use.
Conclusions: Our study emphasises heightened malignancy and mortality rates in SLE+MG cases. The association between immunosuppression, MG incidence and progression warrants further research.
