Abstract
Introduction/Objective

Early diagnosis of rheumatoid arthritis (RA) can improve the prognosis of the disease by reducing joint destruction and achieving a better rate of remission. Musculoskeletal ultrasound (US) has become a potent tool to detect synovitis and erosions. However, until now, there has been a lack of consensus on the US scoring system to help in diagnosing RA early. The purpose of our study was to elaborate a US set suitable for classifying RA patients with inflammatory arthralgia or expressing synovitis and who did not satisfy ACR/EULAR criteria, called “USSRA” (UltraSound Set for Rheumatoid Arthritis).

Materials and methods

A multistep study was conducted. A preliminary set of joints, tendons, and erosions to include in the USSRA were identified through a deep literature screening. The final step of this study was the validation of the final set by international experts in US using a Delphi process.

Results

The preliminary set included 20 joints, 16 tendons, and 8 erosion sites for assessment. After the Delphi process, the changes were to add an assessment of two additional wrist joints and remove one. As for the tendons, two sites were removed from the final set. No changes were proposed for the section erosions. The elementary lesions and scoring system were clarified. The final USSRA forms include 18 joints, 12 tendons, and 8 sites of erosion.

Conclusion

The USSRA is a novel diagnostic tool proposed for detecting early RA in routine practice. The next step will be to assess the reliability of this set in a patient-based exercise.

Resumen
Introducción/Objetivo

El diagnóstico precoz de la artritis reumatoide (AR) puede llevar a que el pronóstico de la enfermedad mejore, puesto que se puede reducir la destrucción articular y obtener una mejor tasa de remisión. La ecografía musculoesquelética (US) se ha convertido en una potente herramienta para detectar sinovitis y erosiones; sin embargo, falta un consenso sobre el sistema de puntuación de ultrasonido para ayudar a diagnosticar la AR de manera temprana. El propósito del estudio que aquí se presenta fue elaborar un conjunto de ultrasonido adecuado para clasificar pacientes con AR con artralgia inflamatoria o expresión de sinovitis y que no cumplían los criterios ACR/EULAR, denominado UltraSound Set for Rheumatoid Arthritis (USSRA).

Materiales y métodos

Se llevó a cabo un estudio de varios pasos. Se identificó un conjunto preliminar de articulaciones, tendones y erosiones para incluir en la USSRA mediante una revisión profunda de la literatura. El paso final de este estudio fue la validación del conjunto final por parte de expertos internacionales en Estados Unidos utilizando un proceso Delphi.

Resultados

El conjunto preliminar incluyó 20 articulaciones, 16 tendones y 8 sitios de erosión para su evaluación. Después del proceso Delphi, los cambios fueron: agregar la evaluación de 2 articulaciones de muñeca adicionales y eliminar una. En cuanto a los tendones, se eliminaron 2 sitios del conjunto final. No se han propuesto cambios para la sección de erosiones. Se aclararon las lesiones elementales y el sistema de puntuación. Los formularios finales de la USSRA incluyen 18 articulaciones, 12 tendones y 8 sitios de erosión.

Conclusión

La USSRA es una herramienta diagnóstica novedosa propuesta para la detección precoz de la AR en la práctica habitual. El próximo paso será evaluar la confiabilidad de este conjunto en un ejercicio basado en el paciente.
