RESUMEN
OBJECTIVE: To assess organ damage, with emphasis on the cardiovascular system, over the different stages of the disease in a large SLE cohort. METHODS: Multicentre, longitudinal study of a cohort of 4219 patients with SLE enrolled in the Spanish Society of Rheumatology Lupus Registry. Organ damage was ascertained using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). We longitudinally analysed SDI (globally and for each domain) over time only in the 1274 patients whose dates of damage events had been recorded. RESULTS: During the first year after diagnosis of SLE, 20% of the 1274 patients presented with new damage manifestations. At years 2 and 3, new damage was recorded in 11% and 9% of patients. The annual percentage of patients with new damage after year 5 decreased to 5%. In the first year with the disease, most damage was accumulated in the musculoskeletal, neuropsychiatric and renal systems; in later stages, most damage was in the musculoskeletal, ocular and cardiovascular systems. Considering 'cerebrovascular accident' and 'claudication for 6 months' as cardiovascular items, the cardiovascular system was the second most affected system during the early stages of SLE, with 19% of the patients who presented with damage affected at first year after diagnosis. During the late stages, 20-25% of the patients presenting with new damage did so in this modified cardiovascular domain of the SDI. CONCLUSIONS: New damage occurs mainly during the first year following diagnosis of SLE. Cardiovascular damage is relevant in both the early and the late stages of the disease. Strategies to prevent cardiovascular damage should be implemented early after diagnosis of SLE.

OBJECTIVES: To provide an overview on the current use of belimumab (BLM) in SLE patients in clinical practice and to examine its efficacy in terms of standardized outcomes, drug survival, as well as patient and safety profiles. METHODS: A longitudinal retrospective multicentre cohort including SLE patients treated with BLM at 18 Spanish centers. Data was collected upon initiation of BLM, at 6 and 12 months after initiation, and at the last recorded visit. Changes in SLEDAI-2K, the proportion of patients who achieved LLDAS and DORIS 2021, and number of flares were compared between visits. Changes in damage, glucocorticoids use and employment status pre-BLM and post-BLM were also assessed. RESULTS: A total of 324 patients were included with a mean follow-up of 3.8 (±2.7) years. LLDAS was attained by 45.8%, 62% and 71% of patients, and DORIS by 24%, 36.2% and 52.5% on successive visits, respectively. Twenty-seven-point two percent of patients were in DORIS ≥ 50% of the visits and a 46% in LLDAS-50. Flares and number of flares were significantly lower one year after treatment with BLM and no changes in damage accrual were observed. Mean (±SD) prednisone dose was significantly reduced over time, with 70 (24%) patients discontinuing GC. CONCLUSION: Our study not only demonstrates belimumab´s efficacy in attaining treat-to-target goals in SLE patients, but also confirms its GC-sparing effect, and its prevention of flares and organ damage accrual.
RESUMEN
OBJECTIVES: To assess agreement between the 2021 Definition Of Remission In SLE (DORIS) and physician-judged lupus activity. METHODS: A cross-sectional analysis was conducted of data from a Spanish prospective multicentre study of SLE patients. We applied the 2021 DORIS criteria and assessed whether remission status based on this definition agreed with remission as per physician clinical judgement and reasons for disagreement between them. RESULTS: Out of 508 patients [92% women; mean age (s.d.): 50.4 years (13.7)] studied, 267 (54.4%) met the criteria for 2021 DORIS remission. Based on physicians' judgement, 277 (55.9%) patients were classified as in remission or serologically active clinically quiescent (SACQ). The overall rate of agreement between these assessments was 81.2% (95% CI: 79.9, 82.9%) with a Cohen's kappa of 0.62 (0.55-0.69). Overall, 46 (9.1%) patients were classified as in remission/SACQ by rheumatologists but did not meet the 2021 DORIS criteria for remission. The main reasons for discrepancies were a clinical SLE Disease Activity Index (cSLEDAI) score >0 in 39 patients, a Physician Global Assessment score >0.5 in five patients, and prednisone >5 mg/day in another five patients. CONCLUSIONS: The 2021 DORIS remission is an achievable target in clinical practice. There is substantial agreement between the DORIS definition and physician-judged remission. The discordance was mainly due to physicians classifying some patients with ongoing mild disease activity as in remission. Thus, the standardized DORIS definition should be used to define the target in a treat-to-target strategy for the management of SLE.

INTRODUCTION: Obstetric complications are more common in women with systemic lupus erythematosus (SLE) than in the general population. OBJECTIVE: To assess pregnancy outcomes in women with SLE from the RELESSER cohort after 12 years of follow-up. METHODS: A multicentre retrospective observational study was conducted. In addition to data from the RELESSER register, data were collected on obstetric/gynaecological variables and treatments received. The number of term pregnancies was compared between women with pregnancies before and after the diagnosis of SLE. Further, clinical and laboratory characteristics were compared between women with pregnancies before and after the diagnosis, on the one hand, and with and without complications during pregnancy, on the other. Bivariate and multivariate analyses were carried out to identify factors potentially associated with complications during pregnancy. RESULTS: A total of 809 women were included, with 1869 pregnancies, of which 1395 reached term. Women with pregnancies before the diagnosis of SLE had more pregnancies (2.37 vs 1.87) and a higher rate of term pregnancies (76.8% vs 69.8%, p < 0.001) compared to those with pregnancies after the diagnosis. Women with pregnancies before the diagnosis were diagnosed at an older age (43.4 vs 34.1 years) and had more comorbidities. No differences were observed between the groups with pregnancies before and after diagnosis in antibody profile, including anti-dsDNA, anti-Sm, anti-Ro, anti-La, lupus anticoagulant, anticardiolipin or anti-beta-2-glycoprotein. Overall, 114 out of the 809 women included in the study experienced complications during pregnancy, including miscarriage, preeclampsia/eclampsia, foetal death, and/or preterm birth. Women with complications had higher rates of antiphospholipid syndrome (40.5% vs 9.9%, p < 0.001) and higher rates of positivity for IgG anticardiolipin (33.9% vs 21.3%, p = 0.005), IgG anti-beta 2 glycoprotein (26.1% vs 14%, p = 0.007), and IgM anti-beta 2 glycoprotein (26.1% vs 16%, p = 0.032) antibodies, although no differences were found regarding lupus anticoagulant. Among the treatments received, only heparin was more commonly used by women with pregnancy complications. We did not find differences in corticosteroid or hydroxychloroquine use. CONCLUSIONS: The likelihood of term pregnancy is higher before the diagnosis of SLE. In our cohort, positivity for anticardiolipin IgG and anti-beta-2- glycoprotein IgG/IgM, but not lupus anticoagulant, was associated with a higher risk of poorer pregnancy outcomes.

OBJECTIVES: To apply the lupus low disease activity state (LLDAS) definition within a large cohort of patients and to assess the agreement between the LLDAS and the physician's subjective evaluation of lupus activity. METHODS: We conducted a cross-sectional analysis of a prospective multicentre study of SLE patients. We applied the LLDAS and assessed whether there was agreement with the clinical status according to the physician's opinion. RESULTS: A total of 508 patients [92% women; mean age 50.4 years (s.d. 3.7)] were recruited and 304 (62.7%) patients were in the LLDAS. According to physician assessment, 430 (86.1%) patients were classified as remission or low activity. Overall agreement between both evaluations was 71.4% (95% CI: 70.1, 70.5) with a Cohen's κ of 0.3 [interquartile range (IQR) 0.22-0.37]. Most cases (96.1%) in the LLDAS were classified as remission or low activity by the expert. Of the patients who did not fulfil the LLDAS, 126 (70.4%) were classified as having remission/low disease activity. The main reasons for these discrepancies were the presence of new manifestations compared with the previous visit and a SLEDAI 2K score >4, mainly based on serological activity. CONCLUSIONS: Almost two-thirds of SLE patients were in the LLDAS. There was a fair correlation between the LLDAS and the physician's evaluation. This agreement improves for patients fulfilling the LLDAS criteria. The discordance between both at defining lupus low activity, the demonstrated association of the LLDAS with better outcomes and the fact that the LLDAS is more stringent than the physician's opinion imply that we should use the LLDAS as a treat-to-target goal.

OBJECTIVES: To analyze the prevalence, incidence, survival and contribution on mortality of major central nervous system (CNS) involvement in systemic lupus erythematosus (SLE). METHODS: Patients fulfilling the SLE 1997 ACR classification criteria from the multicentre, retrospective RELESSER-TRANS (Spanish Society of Rheumatology Lupus Register) were included. Prevalence, incidence and survival rates of major CNS neuropsychiatric (NP)-SLE as a group and the individual NP manifestations cerebrovascular disease (CVD), seizure, psychosis, organic brain syndrome and transverse myelitis were calculated. Furthermore, the contribution of these manifestations on mortality was analysed in Cox regression models adjusted for confounders. RESULTS: A total of 3591 SLE patients were included. Of them, 412 (11.5%) developed a total of 522 major CNS NP-SLE manifestations. 61 patients (12%) with major CNS NP-SLE died. The annual mortality rate for patients with and without ever major CNS NP-SLE was 10.8% vs 3.8%, respectively. Individually, CVD (14%) and organic brain syndrome (15.5%) showed the highest mortality rates. The 10% mortality rate for patients with and without ever major CNS NP-SLE was reached after 12.3â¯vs 22.8 years, respectively. CVD (9.8 years) and organic brain syndrome (7.1 years) reached the 10% mortality rate earlier than other major CNS NP-SLE manifestations. Major CNS NP-SLE (HR 1.85, 1.29-2.67) and more specifically CVD (HR 2.17, 1.41-3.33) and organic brain syndrome (HR 2.11, 1.19-3.74) accounted as independent prognostic factors for poor survival. CONCLUSION: The presentation of major CNS NP-SLE during the disease course contributes to a higher mortality, which may differ depending on the individual NP manifestation. CVD and organic brain syndrome are associated with the highest mortality rates.

OBJECTIVES: To assess the characteristics and risk of lymphoma in a large cohort of patients with SLE. METHODS: A case-cohort analysis was performed within a dynamic cohort of SLE patients from the Spanish Society of Rheumatology Lupus Registry (RELESSER). Clinical and analytical features were compared between the lymphoma SLE group and the control SLE group using an independent-sample Student's t-test or Mann-Whitney test for continuous variables and the χ2 test for categorical variables with Fisher's exact test if necessary. The multivariate analysis was based on a generalized linear model. RESULTS: Twenty-one patients with SLE and lymphoma and 3965 non-lymphoma controls with SLE were studied. Most lymphomas were of B cell origin (n = 15/21), with diffuse large B cell lymphoma being the most frequent histological type (8/21, 38.1%). As in the general population, the risk of lymphoma in SLE was higher in male than in female patients and increased with age. In the lymphoma SLE group, bivariate analysis showed a significantly higher percentage of pericarditis, organic brain syndrome, seizures, vasculitis, haemolytic anaemia, splenomegaly, venous thrombosis and mean modified (excluding lymphoma) SLICC/ACR damage index. In contrast, renal involvement, positive anti-dsDNA, and antimalarials ever were less frequent. CONCLUSIONS: In this large multicentre Spanish cohort, we identified characteristics of SLE that are associated with a higher risk of lymphoma. Antimalarials were significantly negatively associated with risk of lymphoma in SLE patients. Nevertheless, further prospective studies are needed to clarify these findings.

OBJECTIVE: Semaphorin 3B (Sema3B) decreases the migratory and invasive capacities of fibroblast-like synoviocytes (FLS) in rheumatoid arthritis (RA) and suppresses expression of matrix metalloproteinases. We undertook this study to examine the role of Sema3B in a mouse model of arthritis and its expression in RA patients. METHODS: Clinical responses, histologic features, and FLS function were examined in wild-type (WT) and Sema3B-/- mice in a K/BxN serum transfer model of arthritis. Protein and messenger RNA expression of Sema3B in mouse joints and murine FLS, as well as in serum and synovial tissue from patients with arthralgia and patients with RA, was determined using enzyme-linked immunosorbent assay, immunoblotting, quantitative polymerase chain reaction, and RNA sequencing. FLS migration was determined using a wound closure assay. RESULTS: The clinical severity of serum-induced arthritis was significantly higher in Sema3B-/- mice compared to WT mice. This was associated with increased expression of inflammatory mediators and increased migratory capacity of murine FLS. Administration of recombinant mouse Sema3B reduced the clinical severity of serum-induced arthritis and the expression of inflammatory mediators. Sema3B expression was significantly lower in the synovial tissue and serum of patients with established RA compared to patients with arthralgia. Serum Sema3B levels were elevated in patients with arthralgia that later progressed to RA, but not in those who did not develop RA; however, these levels drastically decreased 1 and 2 years after RA development. CONCLUSION: Sema3B expression plays a protective role in a mouse model of arthritis. In RA patients, expression levels of Sema3B in the serum depend on the disease stage, suggesting different regulatory roles in disease onset and progression.

INTRODUCCIÓN: La nefropatía diabética (ND) es una complicación frecuente de la diabetes mellitus (DM), y su diagnóstico suele ser clínico. Sin embargo, en numerosas ocasiones la enfermedad renal que presentan los pacientes diabéticos es debida a otras causas cuyo diagnóstico es histológico. El objetivo del estudio fue determinar los datos clínicos y analíticos predictores de ND y enfermedad renal no diabética (ERND), y elaborar un modelo predictivo (score) para confirmar o descartar ND. MATERIAL Y MÉTODOS: Estudio observacional, transversal y retrospectivo de biopsias renales realizadas en pacientes diabéticos tipo 2 entre 2000 y 2018. RESULTADOS: Se incluyeron 207 pacientes diabéticos con una edad media de 64,5 ± 10,6 años; el 74% eran varones. La biopsia mostró ND en 126 (61%) y en 81 ERND (39%). La retinopatía diabética estaba presente en el 58% de los pacientes con ND y en el 6% del grupo con ERND (p < 0,001). Histología encontrada en la ERND: glomerulopatías primarias (52%), nefroangioesclerosis (16%), nefritis intersticial inmunoalérgica (15%) y vasculitis (8,5%). En el análisis multivariable, la retinopatía (OR 26,7; IC 95%: 6,8-104,5), la isquemia crónica de miembros inferiores (OR 4,37; IC 95%: 1,33-14,3), la insulinoterapia (OR 3,05; IC 95%: 1,13-8,25), una evolución de la DM ≥ 10 años (OR 2,71; IC 95%: 1,1-6,62) y la proteinuria nefrótica (OR 2,91; IC 95%: 1,2-7,1) fueron predictores independientes de ND. La microhematuria, definida como ≥ 10 hematíes/campo (OR 0,032; IC 95%: 0,01-0,11) y el sobrepeso (OR 0,21; IC 95%: 0,08-0,55) lo fueron de ERND. Según el modelo predictivo resultante del estudio multivariable para ND, el rango de puntuación varió de -6 a 8 puntos. Todos los pacientes con un score > 3 era tenían ND, y el 94% de los casos con score ≤ 1 punto fueron ERND. CONCLUSIONES: La ERND es frecuente en pacientes con DM (39%). La etiología más frecuente son las glomerulonefritis primarias. La ausencia de retinopatía y la presencia de microhematuria son altamente sugestivas de ERND. La utilización de un sistema de puntuación facilita la indicación de biopsia renal en pacientes diabéticos
INTRODUCTION: Diabetic nephropathy (DN) is one of the most frequent complications in patients with diabetes mellitus (DM) and its diagnosis is usually established on clinical grounds. However, kidney involvement in some diabetic patients can be due to other causes, and renal biopsy might be needed to exclude them. The aim of our study was to establish the clinical and analytical data that predict DN and no-diabetic renal disease (NDRD), and to develop a predictive model (score) to confirm or dismiss DN. MATERIAL AND METHODS: We conducted a transversal, observational and retrospective study, including renal biopsies performed in type 2 DM patients, between 2000 and 2018. RESULTS: Two hundred seven DM patients were included in our study. The mean age was 64.5 ± 10.6 years and 74% were male. DN was found in 126 (61%) of the biopsies and NDRD in 81 (39%). Diabetic retinopathy was presented in 58% of DN patients, but only in 6% of NDRD patients (P < .001). Patients with NDRD were diagnosed of primary glomerulopathies (52%), nephroangiosclerosis (16%), inmunoallergic interstitial nephritis (15%) and vasculitis (8.5%). In the multivariate analysis, retinopathy (OR 26.7; 95% CI: 6.8-104.5), chronic ischaemia of lower limbs (OR 4,37; 95% CI: 1.33-14.3), insulin therapy (OR 3.05; 95% CI: 1.13-8.25), time course of DM ≥ 10 years (OR 2.71; 95% CI: 1.1-6.62) and nephrotic range proteinuria (OR 2.91; 95% CI: 1.2-7.1) were independent predictors for DN. Microhaematuria defined as ≥ 10 red blood cells per high-power field (OR 0.032; 95% CI: 0.01-0.11) and overweight (OR 0.21; 95% CI: 0.08-0.5) were independent predictors of NDRD. According to the predictive model based on the multivariate analysis, all patients with a score > 3 had DN and 94% of cases with a score ≤ 1 had NDRD (score ranked from -6 to 8 points). CONCLUSIONS: NDRD is common in DM patients (39%), being primary glomerulonephritis the most frequent ethology. The absence of retinopathy and the presence of microhematuria are highly suggestive of NDRD. The use of our predictive model could facilitate the indication of performing a renal biopsy in DM patients
