Interobserver reliability of Masei index validation by a multicenter collaborative group of rheumatologists.

MASEI is the main validated ultrasound score for the evaluation of enthesis. The lack of studies facing the agreement to achieve for the interpretation of the MAdrid Sonographic Enthesis Index (MASEI) among researchers from different centers in multicenter studies is of concern. The aim of this multicenter was to evaluate the interobserver reliability of MASEI. An experienced ultrasonographer-rheumatologist performed ultrasound scans of the areas included in MASEI index in three patients with Ankylosing Spondylitis and Psoriatic Arthritis. Videos were captured. The videos were then evaluated by 24 rheumatologists of the ultrasound working group of the Catalan Society of Rheumatology (EcoCAT). A face-to-face training meeting was held. Ten days after the workshop, the study participants evaluated the videos. A reliability assessment was performed. The ICC for the MASEI scores after the workshop was of 0.97 (95% CI 89-99). Reliability did not vary statistically with examiner experience. Globally, no problems of reliability by structures were seen, and all the ICCs were above 0.90 and improved slightly after the educational program. However, the correlation observed between examiners at plantar aponeursis and triceps tendon was weak. The small variability observed in the results of the index validation in our study, suggests that the MASEI index is reproducible by different observers when those are well trained and show awesome results of the enthesis when examined by ultrasound.

[Functional impairment in psoriatic arthritis. Multicentric study of 343 patients]. / Capacidad funcional en la artropatía psoriásica: análisis de 343 pacientes.

BACKGROUND AND OBJECTIVE: The study is aimed at improving our knowledge about the functional impairment of the psoriatic arthritis through a multicentral series. PATIENTS AND METHOD: We have designed a transversal and multicentral study (centers of the same geographical area), including 343 patients with psoriatic arthritis. Eight medical centers have participated. Patients have been divided depending on the assistential level where they are visited. We have collected the following data: sex, age, assistential level, duration of psoriasis and arthritis, age at onset of psoriasis and arthritis, clinical form, ARA functional impairment, number of tender and swollen joints, presence of dactylitis, distal interphalangeal affection, axial involvement, ostheolisis or nail lesions, erithrocyte sedimentation rate (ESR), C-reactive protein, hemoglobine, leucocites, platelets, HLA-B27 and rheumatoid factor. RESULTS: 7.14% of the patients were significatly disabled (ARA functional class III and IV). 30.32% were patients visited in a primary assistential level, 30.90% in a secondary assistential level and 38.78% a tertiary and universitary hospital. We found statistically significant correlation between III and IV functional classes and age, assistential level, ostheolisis, corticoid treatment, ESR, leucocites, platelets and number of tender joints. CONCLUSIONS: We find a better functional capacity in our patients than in other studies. The inclusion of patients from different assistential levels instead of just patients visited in a tertiary hospital might be the cause of this difference.

Capacidad funcional en la artropatía psoriásica: análisis de 343 pacientes / Functional impairment in psoriatic arthritis. Multicentric study of 343 patients

Fundamento y objetivo: Valorar la repercusión funcional de la artritis psoriásica y analizar los factores asociados en una serie multicéntrica. Pacientes y método: Estudio observacional, transversal y multicéntrico. Se ha incluido a 343 pacientes diagnosticados de artritis psoriásica. Han participado 8 centros de diferentes niveles asistenciales de una misma área geográfica. Se han recogido las variables: sexo; edad; nivel asistencial de atención; duración de la psoriasis y de la artritis; edad de inicio de la psoriasis y de la artritis; patrón de afectación articular dominante; clase funcional según la escala del American College of Rheumatology (I, II, III y IV); número de articulaciones tumefactas y dolorosas (NAD); presencia de dactilitis; afectación de articulaciones interfalángicas distales; afección axial; presencia de osteólisis o artritis mutilante; presencia de onicopatía, velocidad de sedimentación globular (VSG) (mm/primera hora), proteína C reactiva (mg/l), hemoglobina, leucocitos, plaquetas, antígeno de histocompatibilidad B27, factor reumatoide; tratamiento con glucocorticoides. Resultados: El 7,14% de los pacientes presentaba una discapacidad grave (estadio funcional III-IV). El 30,32% eran pacientes atendidos en centros de asistencia primaria; el 30,90%, en centros de asistencia secundaria, y el 38,78%, en un único centro terciario. Las variables que se asociaron de forma significativa (p < 0,05) a una mala capacidad funcional fueron: edad, nivel asistencial, osteólisis, tratamiento con dosis bajas de glucocorticoides, VSG, leucocitos, plaquetas y NAD. Conclusiones: La capacidad funcional de la artritis psoriásica de nuestra serie es mejor que en otras series publicadas. El sesgo de centro puede ser la explicación ya que esta circunstancia se ha producido en nuestra serie
