Remission and low disease activity are associated with lower healthcare costs: results from the Systemic Lupus International Collaborating Clinics (SLICC) inception cohort.

OBJECTIVES: This study aims to determine the independent impact of definitions of remission/low disease activity (LDA) on direct/indirect costs (DCs, ICs) in a multicentre inception cohort. METHODS: Patients from 31 centres in 10 countries were enrolled within 15 months of diagnosis and assessed annually. Five mutually exclusive disease activity states (DAS) were defined as (1) remission off-treatment: clinical (c) SLEDAI-2K=0, without prednisone/immunosuppressants; (2) remission on-treatment: cSLEDAI-2K=0, prednisone ≤5 mg/day and/or maintenance immunosuppressants; (3) LDA-Toronto Cohort (TC): cSLEDAI-2K≤2, without prednisone/immunosuppressants; (4) modified lupus LDA state (mLLDAS): SLEDAI-2K≤4, no activity in major organs/systems, no new activity, prednisone ≤7.5 mg/day and/or maintenance immunosuppressants and (5) active: all remaining assessments.At each assessment, patients were stratified into the most stringent DAS fulfilled and the proportion of time in a DAS since cohort entry was determined. Annual DCs/ICs (2021 Canadian dollars) were based on healthcare use and lost workforce/non-workforce productivity over the preceding year.The association between the proportion of time in a DAS and annual DC/IC was examined through multivariable random-effects linear regressions. RESULTS: 1692 patients were followed a mean of 9.7 years; 49.0% of assessments were active. Remission/LDA (per 25% increase in time in a remission/LDA state vs active) were associated with lower annual DC/IC: remission off-treatment (DC -$C1372; IC -$C2507), remission on-treatment (DC -$C973; IC -$C2604,) LDA-TC (DC -$C1158) and mLLDAS (DC -$C1040). There were no cost differences between remission/LDA states. CONCLUSIONS: Our data suggest that systemic lupus erythematosus patients who achieve remission, both off and on-therapy, and reductions in disease activity incur lower costs than those experiencing persistent disease activity.

Time to diagnosis in systemic lupus erythematosus: Associated factors and its impact on damage accrual and mortality. Data from a multi-ethnic, multinational Latin American lupus cohort.

BACKGROUND: Systemic lupus erythematosus (SLE) often mimics symptoms of other diseases, and the interval between symptom onset and diagnosis may be long in some of these patients. Aims: To describe the characteristics associated with the time to SLE diagnosis and its impact on damage accrual and mortality in patients with SLE from a Latin American inception cohort. METHODS: Patients were from a multi-ethnic, multi-national Latin-American SLE inception cohort. All participating centers had specialized lupus clinics. Socio-demographic, clinical/laboratory, disease activity, damage, and mortality between those with a longer and a shorter time to diagnosis were compared using descriptive statistical tests. Multivariable Cox regression models with damage accrual and mortality as the end points were performed, adjusting for age at SLE diagnosis, gender, ethnicity, level of education, and highest dose of prednisone for damage accrual, plus highest dose of prednisone, baseline SLEDAI, and baseline SDI for mortality. RESULTS: Of the 1437 included in these analyses, the median time to diagnosis was 6.0 months (Q1-Q3 2.4-16.2); in 721 (50.2%) the time to diagnosis was longer than 6 months. Patients whose diagnosis took longer than 6 months were more frequently female, older at diagnosis, of Mestizo ethnicity, not having medical insurance, and having "non-classic" SLE symptoms. Longer time to diagnosis had no impact on either damage accrual (HR 1.09, 95% CI 0.93-1.28, p = 0.300) or mortality (HR 1.37, 95% CI 0.88-2.12, p = 0.200). CONCLUSIONS: In this inception cohort, a maximum time of 24 months with a median of 6 months to SLE diagnosis had no apparent negative impact on disease outcomes (damage accrual and mortality).

Whole-hand and regional bone mineral density involvement in rheumatoid arthritis / Compromiso de la densidad mineral ósea de la mano completa y regional en la artritis reumatoide

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by symmetric polyarthritis that can lead to joint deformity, disability, and osteoporosis. We aimed to evaluate whole hand and regional BMD in RA patients compared to controls. In addition, we evaluated the BMD of dominant versus non-dominant hands in healthy subjects. We included adult female and male RA patients and control subjects matched by age, sex, and BMI. BMD (g/cm2) was measured by DXA in lumbar spine (LS), whole hand, and three regions of interest: carpus, metacarpal bones, and phalanges. Results: 44 control subjects (49.5±11.8 y) and 60 with RA (52.7±12.7 y) were included. Significant lower BMD in RA patients was found in LS (−8.7%), dominant whole hand (−9.5%), carpus, metacarpal bones, and phalanges, and non-dominant whole hand (−8.7%), metacarpal bones, and phalanges compared to controls. A significant positive correlation was found between LS and whole-hand BMD (dominant r=.63, non-dominant r=.67). Finally, the whole hand, metacarpal bones, and carpus BMD measurements were significantly higher in the dominant hand compared to the non-dominant hand without differences in the phalangeal ROI. In conclusion, hand BMD was significantly lower in RA patients compared to control subjects and there was a significant correlation with LS BMD. We demonstrated that BMD measurements of the whole-hand, and different ROI (carpus, metacarpal bones, and phalanges) by DXA would be an easily reproducible technique to evaluate bone loss. In addition, the whole hand, metacarpal bones and carpus BMD measurements were significantly higher in the dominant hand compared to the non-dominant hand without differences in the phalanges.(AU)

La artritis reumatoide (AR) es una enfermedad autoinmune crónica caracterizada por poliartritis simétrica que puede provocar deformidad e incapacidad articular y osteoporosis. Nuestro objetivo fue evaluar la DMO de manos completa y por regiones en los pacientes con AR en comparación con los controles. Se incluyeron pacientes adultos de ambos sexos con AR, y sujetos controles de edad, sexo e IMC similar. La DMO se midió por DXA en columna lumbar (CL), manos completas y 3 regiones de interés: carpo, metacarpianos y falanges. Resultados: se incluyeron 44 sujetos control (49,5±11,8 años) y 60 con AR (52,7±12,7 años). Se encontró una DMO significativamente más baja en los pacientes con AR en CL (−8,7%), mano completa dominante (−9,5%) y mano completa no dominante (−8,7%) en comparación con los sujetos controles. Se encontró una correlación positiva significativa entre la CL y la DMO de la mano completa (dominante, r=0,63; no dominante, r=0,67). Finalmente, la DMO de la mano completa, los huesos metacarpianos y el carpo fueron significativamente más altos en la mano dominante en comparación con la mano no dominante sin diferencias en la región de las falanges. En conclusión, la DMO de la mano fue significativamente menor en los pacientes con AR en comparación con los sujetos controles, y hubo una correlación significativa con la DMO de la CL. Demostramos que las mediciones de la DMO de toda la mano y diferentes ROI (carpo, huesos metacarpianos y falanges) por DXA serían una técnica fácilmente reproducible para evaluar la pérdida ósea. Además, la DMO de la mano completa, los huesos metacarpianos y el carpo fueron significativamente más altos en la mano dominante en comparación con la mano no dominante.(AU)

Accelerated atherosclerosis and cardiovascular disease in systemic lupus erythematosus / Aterosclerosis acelerada y enfermedad cardiovascular en el lupus eritematoso sistémico

ABSTRACT Cardiovascular disease (CVD), particularly coronary heart disease and stroke, is one of the most important causes of morbidity and mortality in patients with systemic lupus erythematosus (SLE). The increased prevalence of CVD and subclinical atherosclerosis, even after adjustment for traditional risk factors, are well established. Several associations with disease-related clinical, genetic and immunological features have been identified. The SLE-specific stratification algorithms with emphasis on composite risk-assessment scores including both traditional risk factors and novel biomarkers is recommended. The clinical complexity of accelerated atherosclerosis will most likely require an integrated approach for the identification, treatment, and intensive study into this aspect of SLE that will ultimately lead to improved cardiovascular outcomes for these patients.

RESUMEN La enfermedad cardiovascular (ECV), en particular la enfermedad coronaria y el ictus, es una de las causas más importantes de morbimortalidad en pacientes con lupus eritematoso sistémico (LES). El aumento en la prevalencia de la ECV y de la aterosclerosis subclínica, aun después del ajuste de los factores de riesgo tradicionales, está claramente establecida. Se han identificado diversas asociaciones con características clínicas, genéticas e inmunológicas relacionadas con la enfermedad. Se recomienda el uso de los algoritmos de estratificación específicos para el LES, con énfasis en los puntajes compuestos de evaluación de riesgo, incluyendo tanto los factores de riesgo tradicionales como los nuevos biomarcadores. La complejidad clínica de la aterosclerosis acelerada muy probablemente requerirá un abordaje integral para la identificación, el tratamiento y el estudio intensivo de este aspecto del LES, que en última instancia permita obtener mejores desenlaces cardiovasculares en estos pacientes.

Efecto de los antimaláricos sobre los diferentes dominios del índice de daño SLICC en pacientes de la cohorte GLADEL / Effect of antimalarials on the different domains of the SLICC damage index in patients of the GLADEL cohort

Objetivos: Estimar el efecto de los antimaláricos (AM) sobre los diferentes dominios del índice de daño SLICC (SDI). Métodos: Se estudiaron pacientes con diagnóstico clínico reciente (≤2 años) de lupus eritematoso sistémico (LES) de la cohorte GLADEL. Variable de estudio: aumento en los dominios del SDI desde el ingreso a la cohorte. Variables independientes: características sociodemográficas, clínicas, laboratorio y tratamientos. El efecto de los AM, como variable dependiente del tiempo, sobre los dominios más frecuentes del SDI (ajustado por factores de confusión) fue examinado con un modelo de regresión de Cox multivariado. Resultados: De 1466 pacientes estudiados, 1049 (72%) recibieron AM con un tiempo medio de exposición de 30 meses (Q1-Q3: 11-57) y 665 pacientes (45%) presentaron daño durante un seguimiento medio de 24 meses (Q1-Q3: 8-55); 301 eventos fueron cutáneos, 208 renales, 149 neuropsiquiátricos, 98 musculoesqueléticos, 88 cardiovasculares y 230 otros. Después de ajustar por factores de confusión, el uso de AM se asoció a un menor riesgo de daño renal (HR 0,652; IC 95%: 0,472-0,901) y en el límite de la significancia estadística (HR 0,701, IC 95%: 0,481-1,024) para el dominio neuropsiquiátrico. Conclusión: En GLADEL, el uso de AM se asoció independientemente a un menor riesgo de daño acumulado renal.

Objective: To assess the effects of antimalarials (AM) over the items of the SLICC Damage Index (SDI). Methods: Patients with recent (≤2 years) diagnosis of systemic lupus erythematosus (SLE) from the GLADEL cohort were studied. End-point: increase in items SDI since cohort entry. Independent variables (socio-demographic, clinical, laboratory and treatment) were included. The effect of AM as a time dependent variable on most frequent SDI items (adjusting for potential confounders) was examined with a multivariable Cox regression model. Results: Of the 1466 patients included in this analysis, 1049 (72%) received AM with a median exposure time of 30 months (Q1-Q3: 11-57). Damage occurred in 665 (45%) patients during a median follow-up time of 24 months (Q1-Q3: 8-55). There were 301 integument, 208 renal, 149 neuropsychiatric, 98 musculoskeletal, 88 cardiovascular and 230 others less frequently represented damages. After adjusting for potential confounders at any time during follow-up, a lower risk of renal damage (HR 0.652; 95% CI: 0.472-0.901) and borderline for neuropsychiatric damage (HR 0.701, 95% CI: 0.481-1.024) was found. Conclusion: In the GLADEL cohort, after adjustment for possible confounding factors, AM were independently associated with a reduced risk of renal damage accrual.

Prevalencia de dislipemia y riesgo cardiovascular elevado en pacientes con artritis reumatoide / Prevalence of dyslipidemia and elevated cardiovascular risk in patients with rheumatoid arthritis

Los objetivos del estudio fueron comparar la frecuencia de riesgo cardiovascular (CV) elevado y dislipemia (DLP) en pacientes con artritis reumatoide (AR) y en controles, identificar variables de la enfermedad asociadas a DLP y estimar el porcentaje de pacientes con AR medicados para DLP. Estudio de corte transversal que incluyó 409 pacientes con AR y 624 controles. El riesgo CV se determinó con las clasificaciones NCEP y SCORE modificados por European League Against Rheumatism (EULAR). Para DLP se utilizó la definición de Adult Treatment Panel III (ATP III). La frecuencia de riesgo CV elevado fue similar en pacientes con AR y controles excepto cuando fue definida por NCEP-EULAR (7% vs. 2%; p = 0.00002). La DLP fue encontrada en el 43% de los pacientes con AR y en el 47% de los controles (p = 0.15). Los pacientes con AR y DLP tuvieron más manifestaciones extra-articulares (36% vs. 24%; p = 0.01) y mayor velocidad de sedimentación globular (VSG) (21 (13-35) vs. 18 (10-30) mm; p = 0.003). El tratamiento recibido para DLP varió según la definición utilizada (11% a 32%). Se encontró mayor riesgo CV en los pacientes con AR solo cuando se definió por NCEP- EULAR. Los pacientes con AR y DLP tuvieron mayor VSG y manifestaciones extra-articulares. La mayoría de los pacientes con AR y DLP no estaban recibiendo tratamiento hipolipemiante.

The objectives of this study were to compare the frequency of dyslipidemia (DLP) and the elevated cardiovascular risk between rheumatoid arthritis (RA) patients and a control group, to identify disease-related factors associated with the presence of DLP and to estimate the frequency of RA patients receiving treatment for DLP. This is a cross sectional study that included 409 RA patients and 624 controls. Cardiovascular (CV) risk was determined using the Framingham score, National Cholesterol Education Program (NCEP) and the Systematic Coronary Risk Evaluation (SCORE) adapted versions according to the European League Against Rheumatism (EULAR) guidelines. DLP was defined according to the Adult Treatment Panel III (ATPIII). The frequency of CV risk was similar in RA patients and controls, except when NCEP-EULAR adapted version for RA was applied (7% vs. 2%; p = 0.00002). A 43% of patients and 47% of controls had DLP (p = 0.15). RA patients with DLP tended to have extra-articular manifestations more frequently (36% vs. 24%; p = 0.01) and higher erythrocyte sedimentation rate (ESR) (21 [13-35] vs. 18 [10-30] mm; p = 0.003). RA patients treated for DLP varied between 11% and 32% according to the definition used. Patients with RA showed an elevated CV risk only when the NCEP-EULAR definition was used. Among RA patients, those with higher ESR and the presence of extra-articular manifestations were more likely to show DLP. The vast majority of patients were not receiving treatment for DLP.
