ABSTRACT
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.

Abatacept (ABA) es una proteína de fusión que inhibe la señal coestimulatoria del linfocito T y está indicado en pacientes con artritis reumatoidea (AR) y artritis crónica juvenil moderada a severa sin respuesta a metotrexato (MTX). ABA ha demostrado su eficacia y seguridad en numerosos estudios controlados, doble ciego, randomizados en poblaciones seleccionadas. La incidencia de eventos adversos en estos estudios oscila entre 80 y 400 por 100 pacientes año. El objetivo del presente estudio fue evaluar la seguridad de ABA en pacientes con AR no seleccionados de la vida real. Material y métodos: Se incluyeron en forma consecutiva todos los pacientes con AR (criterios ACR'87) de 4 centros de reumatología que hubieran recibido al menos 1 dosis de ABA. Se consignaron datos socio-demográficos, características clínicas de la enfermedad, número de infusiones, dosis, y medicación concomitante. Se evaluaron todos los eventos adversos y se determinó la severidad y causalidad. Se consideraron las causas de suspensión del tratamiento. Análisis estadístico: Se evaluó la incidencia de eventos adversos/100 pacientes año de tratamiento, las variables categóricas fueron comparadas por Chi cuadrado y las continuas por test de Student o ANOVA...
Abatacept (ABA) is a fusion protein that inhibits the T cell costimulatorysignal and is indicated in patients with moderate to severe RheumatoidArthritis (RA) and Juvenil Idiopathic Arthritis, not responding to methotrexate. ABA has demonstrated eficacy and security in severalcontrolled, double-blind, randomized studies in selected populations.The objective of the present study was to evaluate security of ABA in patients with RA in the real life. Material and Methods: Consecutive patients with RA (ACR´87 classification) from 4 rheumatology centers that received at least one infusion of ABA were included. Socio-demographic data, disease characteristics, number of infusions, dosis, and concomitant medicationswere registered. All Adverse Events (AE) were evaluated and severityand causality were determined. Causes of treatment discontinuationwas also considered.Statistical analysis: Incidence of AE per 100 patient-years was evaluated, categorical variables were compared by Chi2 and continuous variables by Student T-test or ANOVA. Results: 184 patients were included, 155 (84.2%) were female, median age was 56 years (IQR 48-64) and median duration of disease was 13 years (IQR 8-18). 94.7% of the patients were rheumatoidfactor-positive and 82% had erosive disease. 90% were treatedwith concomitant DMARDs, methotrexate being the most frequent(76.5%). In 67% of the patients ABA was the first biologic agent used, and 23% had previously received at least one anti-TNF. Median duration of treatment with ABA was 24 months (IQR 11-34) and median number of infusions was 23 (IQR 10-34). Incidence of all AE was 46.18 per 100 patient-years, being the more frequents: Infections (27.3 per 100 patient-years), and infusion reactions (8.6 per100 patient-years)...
