Incidence, associated factors and clinical impact of severe infections in a large, multicentric cohort of patients with systemic lupus erythematosus
OBJECTIVES:
To estimate the incidence of severe infection and investigate the associated factors and clinical impact in a large systemic lupus erythematosus (SLE) retrospective cohort.
METHODS:
All patients in the Spanish Rheumatology Society Lupus Registry (RELESSER) who meet ?4 ACR-97 SLE criteria were retrospectively investigated for severe infections. Patients with and without infections were compared in terms of SLE severity, damage, comorbidities, and demographic characteristics. A multivariable Cox regression model was built to calculate hazard ratios (HRs) for the first infection.
RESULTS:
A total of 3658 SLE patients were included: 90% female, median age 32.9 years (DQ 9.7), and mean follow-up (months) 120.2 (±87.6). A total of 705 (19.3%) patients suffered ?1 severe infection. Total severe infections recorded in these patients numbered 1227. The incidence rate was 29.2 (95% CI: 27.6-30.9) infections per 1000 patient years. Time from first infection to second infection was significantly shorter than time from diagnosis to first infection (p < 0.000). Although respiratory infections were the most common (35.5%), bloodstream infections were the most frequent cause of mortality by infection (42.0%). In the Cox regression analysis, the following were all associated with infection: age at diagnosis (HR = 1.016, 95% CI: 1.009-1.023), Latin-American (Amerindian-Mestizo) ethnicity (HR = 2.151, 95% CI: 1.539-3.005), corticosteroids (?10mg/day) (HR = 1.271, 95% CI: 1.034-1.561), immunosuppressors (HR = 1.348, 95% CI: 1.079-1.684), hospitalization by SLE (HR = 2.567, 95% CI: 1.905-3.459), Katz severity index (HR = 1.160, 95% CI: 1.105-1.217), SLICC/ACR damage index (HR = 1.069, 95% CI: 1.031-1.108), and smoking (HR = 1.332, 95% CI: 1.121-1.583). Duration of antimalarial use (months) proved protective (HR = 0.998, 95% CI: 0.997-0.999).
CONCLUSIONS:
Severe infection constitutes a predictor of poor prognosis in SLE patients, is more common in Latin-Americans and is associated with age, previous infection, and smoking. Antimalarials exerted a protective effect.Spanish Foundation of Rheumatology. FIS/ISCIII (grant number

Cardiovascular events in Systemic Lupus Erythematosus: a nationwide study in Spain from the RELESSER Registry
This article estimates the frequency of cardiovascular (CV) events that occurred after diagnosis in a large Spanish cohort of patients with systemic lupus erythematosus (SLE) and investigates the main risk factors for atherosclerosis. RELESSER is a nationwide multicenter, hospital-based registry of SLE patients. This is a cross-sectional study. Demographic and clinical variables, the presence of traditional risk factors, and CV events were collected. A CV event was defined as a myocardial infarction, angina, stroke, and/or peripheral artery disease. Multiple logistic regression analysis was performed to investigate the possible risk factors for atherosclerosis. From 2011 to 2012, 3658 SLE patients were enrolled. Of these, 374 (10.9%) patients suffered at least a CV event. In 269 (7.4%) patients, the CV events occurred after SLE diagnosis (86.2% women, median [interquartile range] age 54.9 years [43.2-66.1], and SLE duration of 212.0 months [120.8-289.0]). Strokes (5.7%) were the most frequent CV event, followed by ischemic heart disease (3.8%) and peripheral artery disease (2.2%). Multivariate analysis identified age (odds ratio [95% confidence interval], 1.03 [1.02-1.04]), hypertension (1.71 [1.20-2.44]), smoking (1.48 [1.06-2.07]), diabetes (2.2 [1.32-3.74]), dyslipidemia (2.18 [1.54-3.09]), neurolupus (2.42 [1.56-3.75]), valvulopathy (2.44 [1.34-4.26]), serositis (1.54 [1.09-2.18]), antiphospholipid antibodies (1.57 [1.13-2.17]), low complement (1.81 [1.12-2.93]), and azathioprine (1.47 [1.04-2.07]) as risk factors for CV events. We have confirmed that SLE patients suffer a high prevalence of premature CV disease. Both traditional and nontraditional risk factors contribute to this higher prevalence. Although it needs to be verified with future studies, our study also shows-for the first time-an association between diabetes and CV events in SLE patients
Biologic Therapy in Refractory Non-Multiple Sclerosis Optic Neuritis Isolated or Associated to Immune Mediated Inflammatory Diseases. A Multicenter Study
We aimed to assess the e cacy of biologic therapy in refractory non-Multiple Sclerosis
(MS) Optic Neuritis (ON), a condition more infrequent, chronic and severe than MS ON. This was
an open-label multicenter study of patients with non-MS ON refractory to systemic corticosteroids
and at least one conventional immunosuppressive drug. The main outcomes were Best Corrected
Visual Acuity (BCVA) and both Macular Thickness (MT) and Retinal Nerve Fiber Layer (RNFL) using
Optical Coherence Tomography (OCT). These outcome variables were assessed at baseline, 1 week,
and 1, 3, 6 and 12 months after biologic therapy initiation. Remission was defined as the absence of ON symptoms and signs that lasted longer than 24 h, with or without an associated new lesion
on magnetic resonance imaging with gadolinium contrast agents for at least 3 months. We studied
19 patients (11 women/8 men; mean age, 34.8 13.9 years). The underlying diseases were Bechet?s
disease (n = 5), neuromyelitis optica (n = 3), systemic lupus erythematosus (n = 2), sarcoidosis (n = 1),
relapsing polychondritis (n = 1) and anti-neutrophil cytoplasmic antibody -associated vasculitis (n = 1).
It was idiopathic in 6 patients. The first biologic agent used in each patient was: adalimumab (n = 6),
rituximab (n = 6), infliximab (n = 5) and tocilizumab (n = 2). A second immunosuppressive drug was
simultaneously used in 11 patients: methotrexate (n = 11), azathioprine (n = 2), mycophenolate mofetil
(n = 1) and hydroxychloroquine (n = 1). Improvement of the main outcomes was observed after 1 year
of therapy when compared with baseline data: mean SD BCVA (0.8 0.3 LogMAR vs. 0.6 0.3
LogMAR; p = 0.03), mean SD RNFL (190.5 175.4 m vs. 183.4 139.5 m; p = 0.02), mean SD
MT (270.7 23.2 m vs. 369.6 137.4 m; p = 0.03). Besides, the median (IQR) prednisone-dose was
also reduced from 40 (10?61.5) mg/day at baseline to. 2.5 (0?5) mg/day after one year of follow-up;
p = 0.001. After a mean SD follow-up of 35 months, 15 patients (78.9%) achieved ocular remission,
and 2 (10.5%) experienced severe adverse events. Biologic therapy is e ective in patients with
refractory non-MS ON
Comprehensive description of clinical characteristics of a large systemic Lupus Erythematosus Cohort from the Spanish Rheumatology Society Lupus Registry (RELESSER) with emphasis on complete versus incomplete lupus differences
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by multiple organ involvement and pronounced racial and ethnic heterogeneity. The aims of the present work were (1) to describe the cumulative clinical characteristics of those patients included in the Spanish Rheumatology Society SLE Registry (RELESSER), focusing on the differences between patients who fulfilled the 1997 ACR-SLE criteria versus those with less than 4 criteria (hereafter designated as incomplete SLE (iSLE)) and (2) to compare SLE patient characteristics with those documented in other multicentric SLE registries. RELESSER is a multicenter hospital-based registry, with a collection of data from a large, representative sample of adult patients with SLE (1997 ACR criteria) seen at Spanish rheumatology departments. The registry includes demographic data, comprehensive descriptions of clinical manifestations, as well as information about disease activity and severity, cumulative damage, comorbidities, treatments and mortality, using variables with highly standardized definitions. A total of 4.024 SLE patients (91% with â„4 ACR criteria) were included. Ninety percent were women with a mean age at diagnosis of 35.4 years and a median duration of disease of 11.0 years. As expected, most SLE manifestations were more frequent in SLE patients than in iSLE ones and every one of the ACR criteria was also associated with SLE condition; this was particularly true of malar rash, oral ulcers and renal disorder. The analysis-adjusted by gender, age at diagnosis, and disease duration-revealed that higher disease activity, damage and SLE severity index are associated with SLE [OR: 1.14; 95% CI: 1.08-1.20 (Pâ<â0.001); 1.29; 95% CI: 1.15-1.44 (Pâ<â0.001); and 2.10; 95% CI: 1.83-2.42 (Pâ<â0.001), respectively]. These results support the hypothesis that iSLE behaves as a relative stable and mild disease. SLE patients from the RELESSER register do not appear to differ substantially from other Caucasian populations and although activity [median SELENA-SLEDA: 2 (IQ: 0-4)], damage [median SLICC/ACR/DI: 1 (IQ: 0-2)], and severity [median KATZ index: 2 (IQ: 1-3)] scores were low, 1 of every 4 deaths was due to SLE activity. RELESSER represents the largest European SLE registry established to date, providing comprehensive, reliable and updated information on SLE in the southern European population

We evaluated the performance of the new criteria with regard to disease duration, sex and race/ethnicity, and compared its performance against the Systemic Lupus International Collaborating Clinics (SLICC) 2012 and ACR 1982/1997 criteria. METHODS: Twenty-one SLE centres from 16 countries submitted SLE cases and mimicking controls to form the validation cohort. The sensitivity and specificity of the EULAR/ACR 2019, SLICC 2012 and ACR 1982/1997 criteria were evaluated. RESULTS: The cohort consisted of female (n=1098), male (n=172), Asian (n=118), black (n=68), Hispanic (n=124) and white (n=941) patients; with an SLE duration of 1 to <3 years (n=196) and â„5 years (n=879). Among patients with 1 to <3 years disease duration, the EULAR/ACR criteria had better sensitivity than the ACR criteria (97% vs 81%). The EULAR/ACR criteria performed well in men (sensitivity 93%, specificity 96%) and women (sensitivity 97%, specificity 94%). Among women, the EULAR/ACR criteria had better sensitivity than the ACR criteria (97% vs 83%) and better specificity than the SLICC criteria (94% vs 82%). Among white patients, the EULAR/ACR criteria had better sensitivity than the ACR criteria (95% vs 83%) and better specificity than the SLICC criteria (94% vs 83%). The EULAR/ACR criteria performed well among black patients (sensitivity of 98%, specificity 100%), and had better sensitivity than the ACR criteria among Hispanic patients (100% vs 86%) and Asian patients (97% vs 77%). CONCLUSIONS: The EULAR/ACR 2019 criteria perform well among patients with early disease, men, women, white, black, Hispanic and Asian patients. These criteria have superior sensitivity than the ACR criteria and/or superior specificity than the SLICC criteria across many subgroups
Pure Membranous Lupus Nephritis: Description of a Cohort of 150 Patients and Review of the Literature
Objectives The course and long-term outcome of pure membranous lupus nephritis (MLN) are little understood. The aims of this study are to evaluate the clinical features, course, outcome and prognostic indicators in pure MLN and to determine the impact of ethnicity and the type of health insurance on the course and prognosis of pure MLN. Methods We conducted a retrospective review of medical records of 150 patients with pure MLN from Spain and the USA. Results Mean age was 34.2±12.5 and 80% were women. Sixty-eight percent of patients had nephrotic syndrome at diagnosis. The average serum creatinine was 0.98±0.78mg/dl. Six percent of patients died and 5.3% developed end-stage renal disease (ESRD). ESRD was predicted by male sex, hypertension, dyslipidemia, high basal 24h-proteinuria, high basal serum creatinine and a low basal creatinine clearance. Age, cardiac insufficiency, peripheral artheriopathy, hemodialysis and not having received mycophenolate mofetil or antimalarials for MLN predicted death. Conclusions Pure MLN frequently presents with nephrotic syndrome, high proteinuria and normal serum creatinine. Its prognosis is favourable in maintaining renal function although proteinuria usually persists over time. Baseline cardiovascular disease and not having a health insurance are related with poor prognosis

European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) SLE classification criteria item performance.
BACKGROUND/OBJECTIVES: The European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) 2019 classification criteria for systemic lupus erythematosus system showed high specificity, while attaining also high sensitivity. We hereby analysed the performance of the individual criteria items and their contribution to the overall performance of the criteria. METHODS: We combined the EULAR/ACR derivation and validation cohorts for a total of 1197 systemic lupus erythematosus (SLE) and n=1074 non-SLE patients with a variety of conditions mimicking SLE, such as other autoimmune diseases, and calculated the sensitivity and specificity for antinuclear antibodies (ANA) and the 23 specific criteria items. We also tested performance omitting the EULAR/ACR criteria attribution rule, which defines that items are only counted if not more likely explained by a cause other than SLE. RESULTS: Positive ANA, the new entry criterion, was 99.5% sensitive, but only 19.4% specific, against a non-SLE population that included other inflammatory rheumatic, infectious, malignant and metabolic diseases. The specific criteria items were highly variable in sensitivity (from 0.42% for delirium and 1.84% for psychosis to 75.6% for antibodies to double-stranded DNA), but their specificity was uniformly high, with low C3 or C4 (83.0%) and leucopenia 80% for all items, explaining the higher overall specificity of the criteria set
Comorbidities (excluding lymphoma) in Sjögren's syndrome
The information about comorbidities (excluding lymphoma) in primary Sjögren's syndrome (pSS) is relatively scarce. Cardiovascular disease, infections, musculoskeletal conditions or malignancy are likely the most relevant comorbid conditions in pSS. Different infections (particularly oral candidal infections) and fibromyalgia are extremely frequent in the daily clinical practice. On the other hand, the incidence of cardiovascular events and cancer in pSS is low, so information about them comes from large epidemiological studies or meta-analysis. For this reason, preclinical vascular disease is investigated by different techniques, demonstrating the presence of early atherosclerosis in pSS patients. Coronary events could be slightly more frequent in pSS than in the general population. The overall risk of malignancy in pSS patients seems to be slightly increased, likely due to excess occurrence of lymphoma. An association between pSS and thyroid cancer might exist, although it should be confirmed by further investigations
Effectiveness and cost-effectiveness of a multicomponent intervention to implement a clinical practice guideline for systemic lupus erythematosus: protocol for a cluster-randomized controlled trial
BACKGROUND: Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease with significant potential morbidity and mortality. Substantial gaps have been documented between the development and dissemination of clinical practice guidelines (CPG) and their implementation in practice. The aim of this study is to assess the effectiveness and cost-effectiveness of a multi-component knowledge transfer intervention to implement a CPG for the management of SLE (CPG-SLE). METHODS: The study is an open, multicentre, controlled trial with random allocation by clusters to intervention or control. Clusters are four public university hospitals of the Canary Islands Health Service where rheumatologists are invited to participate. Patients diagnosed with SLE at least one year prior to recruitment are selected. Rheumatologists in intervention group receive a short educational group programme to both update their knowledge about SLE management according to CPG-SLE recommendations and to acquire knowledge and training on use of the patient-centred approach, a decision support tool embedded in the electronic clinical record and a quarterly feedback report containing information on management of SLE patients. Primary endpoint is change in self-perceived disease activity. Secondary endpoints are adherence of professionals to CPG-SLE recommendations, health-related quality of life, patient perception of their participation in decision making, attitudes of professionals towards shared decision making, knowledge of professionals about SLE and use of healthcare resources. Calculated sample size is 412 patients. Data will be collected from questionnaires and clinical records. Length of follow-up will be 18âmonths. Multilevel mixed models with repeated time measurements will be used to analyze changes in outcomes over time. Cost-effectiveness, from both social and healthcare services perspectives, will be analyzed by measuring effectiveness in terms of quality-adjusted life years gained. Deterministic and probabilistic sensitivity analyses are planned. DISCUSSION: Impact of CPGs in clinical practice could be improved by applying proven value interventions to implement them. The results of this ongoing trial are expected to generate important scientifically valid and reproducible information not only on clinical effectiveness but also on cost-effectiveness of a multi-component intervention for implementation of a CPG based on communication technologies for chronic patients in the hospital setting.

Comparable effects of traditional cardiovascular risk factors on subclinical atherosclerosis in systemic lupus erythematosus and rheumatoid arthritis
OBJECTIVES:
Patients with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) have an increased premature prevalence of atherosclerosis. We aimed to determine whether there are differences in the prevalence of classic cardiovascular risk factors between SLE and RA. We also analysed the effect of traditional cardiovascular risk factors on the development of subclinical atherosclerosis in both conditions and if some disease-characteristic features are associated with these traditional cardiovascular risk factors.
METHODS:
This was a cross-sectional study encompassing 602 individuals, 276 SLE and 326 RA patients. Subclinical atherosclerosis (presence of carotid plaques and carotid intima-media thickness [cIMT]) was determined by carotid ultrasonography. A multivariable regression analysis was performed to evaluate whether classic cardiovascular-related risk factors differentially influence subclinical carotid atherosclerosis in SLE compared to RA patients.
RESULTS:
Age (interaction factor [if] p=0.000), hypertension (if p=0.034), and diabetes (if p=0.037) had a higher effect on cIMT in RA than in SLE subjects. However, these traditional cardiovascular factors did not yield different effects on the presence of carotid plaques in RA and SLE when the univariate interaction was analysed. In addition, no differences were found in the influence of hypertension, diabetes, dyslipidaemia or current smoking on cIMT or carotid plaque after adjusting for demographics, the presence of other traditional cardiovascular factors, and disease-related data. Moreover, the additive effect of several cardiovascular risk factors on the subclinical carotid atherosclerosis did not differ between the two diseases.
CONCLUSIONS:
The influence of traditional cardiovascular risk factors on cIMT and carotid plaque is similar in RA and SLE.Spanish Ministry of Health, Subdireccion General de Evaluacion y Fomento de la Investigacion, Plan Estatal de Investigacion Cientifica y Tecnica y de Innovacion 2013-2016Fondo Europeo de Desarrollo Regional - FEDER - (Fondo de Investigaciones Sanitarias) (FIS PI14/00394; PI17/00083)Fondo de Investigacion Sanitaria of the Instituto de Salud Carlos III (ISCIII, Health Ministry, Spain) (PI06/0024)4.473 JCR (2020) Q2, Rheumatology1.184 SJR (2020) Q2, 88/213 ImmunologyNo data IDR 2020UE
