Resumen Objetivos Analizar el riesgo de fractura calculado por FRAX® y la frecuencia de alto riesgo de fractura en la poblacion general en Espana. Metodos EPISER2016 es un estudio transversal multicentrico de base poblacional de la prevalencia de las enfermedades reumaticas en poblacion adulta en Espana. Un total de 3.154 sujetos de edad igual o superior a 40 anos (1.184 hombres y 1.970 mujeres) se seleccionaron mediante muestreo aleatorio estratificado. Las preguntas relacionadas con los factores de riesgo de fractura se realizaron mediante encuesta telefonica. El riesgo de fractura principal (RFP) y de cadera (RFC) se calcularon con la version espanola de la herramienta FRAX®, sin la inclusion de la densidad mineral osea. Para definir alto riesgo de fractura, se utilizaron los umbrales RFP ≥ 20%, RFP ≥ 10%, RFP ≥ 7,5% y RFC ≥ 3%. Resultados La mediana (rango intercuartilico) del RFP fue 2,61% (1,55-6,34%) en mujeres y 1,67% (1,15-2,87%) en hombres; la del RFC fue 0,39% (0,14-1,86%) y 0,18% (0,07-0,77%). El 3,83% de las mujeres y ningun hombre tenian un RFP ≥ 20%; el 15,71% y el 1,14% tenian un RFP ≥ 10%; el 20,62% y el 2,21%, un RFP ≥ 7,5%; y el 19,27% y el 8,05%, un RFC ≥ 3%. En las mujeres de 65 anos o mas, el RFC fue alto en el 58,09%. Conclusiones EPISER2016 nos ha permitido conocer el riesgo de fractura calculado por FRAX® y la prevalencia de alto riesgo de fractura en la poblacion general segun los diversos umbrales utilizados en Espana.

Resumen Objetivos Describir la metodologia del estudio de prevalencia de las enfermedades reumaticas en la poblacion adulta en Espana, EPISER 2016, asi como sus fortalezas y limitaciones. El objetivo del proyecto es estimar la prevalencia de artritis reumatoide (AR), artropatia psoriasica (APs), espondilitis anquilosante (EA), lupus eritematoso sistemico (LES), sindrome de Sjogren (SS), artrosis (de rodilla, cadera, manos, columna cervical y lumbar), fibromialgia, gota y fractura osteoporotica clinica. Material y metodo Estudio transversal multicentrico de base poblacional en el que participan 45 municipios de las 17 comunidades autonomas. La poblacion de referencia esta compuesta por adultos de 20 o mas anos residentes en Espana. La recogida de informacion se llevara a cabo mediante encuesta telefonica empleando el sistema Computer Assisted Telephone Interview (CATI). Las sospechas diagnosticas y los diagnosticos autorreferidos seran estudiadas por reumatologos del hospital de referencia de los municipios seleccionados. Analisis estadistico: se calcularan las prevalencias de enfermedades reumaticas mediante estimadores y sus IC del 95%. Se calcularan factores de ponderacion en funcion de la probabilidad de seleccion en cada una de las etapas del muestreo. Se tendra en cuenta la distribucion de la poblacion en Espana segun datos del Instituto Nacional de Estadistica. Conclusiones Los cambios sociodemograficos y en habitos de vida durante los ultimos 16 anos justifican la realizacion de EPISER 2016. El estudio ofrecera datos actualizados de prevalencia en AR, EA, APs, LES, SS, artrosis, fibromialgia, gota y fractura osteoporotica clinica. Los resultados permitiran comparar los datos con estudios de otros paises y con el EPISER 2000.

Objective SLE can affect any part of the gastrointestinal (GI) tract. GI symptoms are reported to occur in >50% of SLE patients. To describe the GI manifestations of SLE in the RELESSER (Registry of SLE Patients of the Spanish Society of Rheumatology) cohort and to determine whether these are associated with a more severe disease, damage accrual and a worse prognosis. Methods We conducted a nationwide, retrospective, multicentre, cross-sectional cohort study of 3658 SLE patients who fulfil ≥4 ACR-97 criteria. Data on demographics, disease characteristics, activity (SLEDAI-2K or BILAG), damage (SLICC/ACR/DI) and therapies were collected. Demographic and clinical characteristics were compared between lupus patients with and without GI damage to establish whether GI damage is associated with a more severe disease. Results From 3654 lupus patients, 3.7% developed GI damage. Patients in this group (group 1) were older, they had longer disease duration, and were more likely to have vasculitis, renal disease and serositis than patients without GI damage (group 2). Hospitalizations and mortality were significantly higher in group 1. Patients in group 1 had higher modified SDI (SLICC Damage Index). The presence of oral ulcers reduced the risk of developing damage in 33% of patients. Conclusion Having GI damage is associated with a worse prognosis. Patients on a high dose of glucocorticoids are at higher risk of developing GI damage which reinforces the strategy of minimizing glucocorticoids. Oral ulcers appear to decrease the risk of GI damage.

Objective To assess the efficacy of abatacept (ABA) in RA patients with interstitial lung disease (ILD) (RA-ILD). Methods This was an observational, multicentre study of RA-ILD patients treated with at least one dose of ABA. ILD was diagnosed by high-resolution CT (HRCT). We analysed the following variables at baseline (ABA initiation), 12 months and at the end of the follow-up: Modified Medical Research Council (MMRC) scale (1-point change), forced vital capacity (FVC) or diffusion lung capacity for carbon monoxide (DLCO) (improvement or worsening ≥10%), HRCT, DAS on 28 joints evaluated using the ESR (DAS28ESR) and CS-sparing effect. Results We studied 263 RA-ILD patients [150 women/113 men; mean (s.d.) age 64.6 (10) years]. At baseline, they had a median duration of ILD of 1 (interquartile range 0.25–3.44) years, moderate or severe degree of dyspnoea (MMRC grade 2, 3 or 4) (40.3%), FVC (% of the predicted) mean (s.d.) 85.9 (21.8)%, DLCO (% of the predicted) 65.7 (18.3) and DAS28ESR 4.5 (1.5). The ILD patterns were: usual interstitial pneumonia (UIP) (40.3%), non-specific interstitial pneumonia (NSIP) (31.9%) and others (27.8%). ABA was prescribed at standard dose, i.v. (25.5%) or s.c. (74.5%). After a median follow-up of 12 (6–36) months the following variables did not show worsening: dyspnoea (MMRC) (91.9%); FVC (87.7%); DLCO (90.6%); and chest HRCT (76.6%). A significant improvement of DAS28ESR from 4.5 (1.5) to 3.1 (1.3) at the end of follow-up (P Conclusion ABA may be an effective and safe treatment for patients with RA-ILD.

Aim: To describe the methodology of the EPISER 2016 (study of the prevalence of rheumatic diseases in adult population in Spain), as well its strengths and limitations. The aim of this study is to estimate the prevalence of rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), Sjogren's syndrome (SS), osteoarthritis (knee, hip, hands, and cervical and lumbar spine), fibromyalgia, gout and clinical osteoporotic fracture. Material and method: Population-based, multicenter, cross-sectional study, with the participation of 45 municipalities in the 17 Spanish autonomous communities. The reference population will consist of adults aged 20 years and over residing in Spain. A computer-assisted telephone interview (CATI) system will be used for data collection. Diagnostic suspicions and diagnoses received by the participants will be studied by rheumatologists in the referral hospitals in the selected municipalities. Statistical analysis: the prevalence of the rheumatic diseases will be calculated using estimators and their 95% confidence intervals. Weights will be calculated in each of the sampling stages in accordance with the probability of selection. The distribution of the population in Spain will be obtained from the Spanish Statistics Institute. Conclusions: Sociodemographic and lifestyle changes over the last 16 years justify EPISER 2016. This study will provide current data about the prevalences of RA, AS, PsA, SLE, SS, osteoarthritis, fibromyalgia, gout and clinical osteoporotic fracture. The results will allow comparisons with studies from other countries and EPISER 2000. (C) 2017 Elsevier Espana, S.L.U. and Sociedad Espanola de Reumatologia y Colegio Mexicano de Reumatologia.
