RESUMO

INTRODUCCIÓN: La arteritis de células gigantes (ACG) es una vasculitis que afecta a arterias de mediano y gran calibre. La biopsia de la arteria temporal es la técnica diagnóstica de elección. Atendiendo a la demanda asistencial que supone, pretendemos evaluar la utilidad de la ecografía Doppler en los pacientes con sospecha de ACG, su sensibilidad y especificidad como prueba diagnóstica y si puede suplir a la biopsia. MATERIALES Y MÉTODOS: Se ha realizado un estudio prospectivo de 57 pacientes entre febrero de 2015 y julio de 2016, que han sido diagnosticados con exploración mediante ecografía Doppler y biopsia de arteria temporal. RESULTADOS: Fueron incluidos 57 pacientes, de los cuales 3 fallecieron durante el seguimiento y una paciente fue excluida del estudio al negarse a la biopsia. Otros 21 pacientes fueron diagnosticados de ACG por un especialista reumatólogo tras un mínimo de 6 meses de seguimiento. Presentaron ecografía positiva 22 pacientes, de los cuales 8 fueron diagnosticados de ACG y 4 de polimialgia reumática. En nuestro estudio, la sensibilidad de la ecografía es del 42,6% y la especificidad es del 65,7%. Otros 19 pacientes presentaron biopsia positiva: todos ellos fueron diagnosticados de ACG. La biopsia presentó una sensibilidad de un 73,7% y una especificidad de un 100%. CONCLUSIONES: Según nuestro estudio, la utilidad de la ecografía es limitada y son necesarias nuevas investigaciones para determinar su papel en esta entidad


BACKGROUND: Giant cell arteritis (GCA) is a vasculitis that affects medium- and large-sized arteries. Temporal artery biopsy is the gold standard for diagnosis. In view of the high demand for temporal biopsies, the purpose of this study is to evaluate the usefulness of Doppler ultrasonography in patients with suspected giant cell arteritis, to determine its sensitivity and specificity as a diagnostic test and to determine whether it would be possible to substitute biopsy for ultrasonography. MATERIALS AND METHODS: A prospective study was undertaken including 57 patients from February 2015 to July 2016, who have undergone both ultrasonography and temporal biopsy. RESULTS: A total of 57 patients were included, 3of whom died during the follow-up, and a patient was excluded from the study when she refused to have the biopsy. Another 21 patients were diagnosed with GCA by a rheumatologist after a minimum of 6 months of follow-up and 22 patients had positive ultrasonography, 8 of whom were diagnosed with GCA and 4 with polymyalgia rheumatica. In our study, the sensitivity of ultrasonography was 42.6%, and the specificity was 65.7%. A total of 19 patients had a positive biopsy, all of them were diagnosed with GCA. In our study, the sensitivity of the biopsy was 73.7% and the specificity was 100%. CONCLUSIONS: In view of the data from our study, the usefulness of ultrasonography is questionable, and research about the role of ultrasonography in this disease should be further studied

RESUMO

Si bien la radiografía es la técnica de imagen de primera línea en las espondiloartritis (EspA), tanto esta como la tomografía computarizada permiten apreciar la evolución del daño estructural a medio y largo plazo, pero son insensibles para demostrar entesitis, sacroilitis, sinovitis o tenosinovitis (salvo con contraste), y su rápida modificación con el tratamiento. El uso de técnicas como la ecografía o la resonancia magnética facilitan el diagnóstico precoz, lo que permite modificar el curso de la enfermedad con tratamientos más tempranos y controlar de forma más precisa la respuesta al tratamiento, así como controlar los cambios inflamatorios a corto plazo, apoyados por los hallazgos clínicos y de laboratorio, principalmente aquellos que puedan ofrecer dudas. El uso generalizado de estas técnicas de imagen para el control de las EspA no está aceptado, por costes y falta de evidencia, pero en casos seleccionados y con la colaboración entre radiólogos y reumatólogos pueden ser sumamente importantes en la evaluación de pacientes con sospecha de actividad, y de ella depende tanto la buena evolución del paciente como el uso adecuado de los recursos. El gasto en las pruebas de diagnóstico por la imagen es importante, pero puede ayudar a aprovechar mejor los recursos en las EspA


Although radiography is the first-line imaging technique in spondyloarthritis (SpA), both radiography and computed tomography allow assessment of the progression of structural damage in the medium- and long-term. However, both have poor sensitivity in demonstrating enthesitis, sacroiliitis, synovitis and tenosynovitis (except with contrast medium) and its rapid modification with treatment. The use of techniques such as ultrasound and magnetic resonance aid early diagnosis, which allows modification of the course of the disease with earlier treatment and more precise control of treatment response by monitoring shortterm inflammatory changes and supporting clinical and laboratory findings, mainly those that may raise doubts. The generalised use of these imaging techniques to monitor SpA is not accepted, due to their costs and lack of evidence. However, in selected patients, and with collaboration between radiologists and rheumatologists, they can be extremely important in the assessment of patients with suspected activity, which is essential for both good patient outcomes and adequate resource use. Imaging tests are expensive but may help to make better use of resources in SpA

RESUMO

La ausencia de consenso sobre la evaluación óptima de la actividad de la espondiloartritis obstaculiza el desarrollo de un tratamiento por objetivos. Es cierto que existen medidas de respuesta, tanto para la afectación axial como para la periférica, como ASAS, BASDAI o ASDAS, DAS28 o DAPSA, basadas esencialmente en las manifestaciones clínicas. Esta medidas valoran función e inflamación aunque excluyen progresión radiográfica, por lo que parece importante el apoyo de determinadas pruebas de imagen para una valoración más objetiva del resultado. Entre ellas, las pruebas que han demostrado más utilidad son la ecografía y la resonancia magnética. La ecografía se utiliza fundamentalmente en la afectación periférica (articular, entesis y dactilitis) para evaluar inflamación y progresión radiográfica, y la resonancia fundamentalmente en la afectación axial. Por todo ello se requiere más formación para la autosuficiencia del reumatólogo en la utilización de la ecografía, así como protocolos bien establecidos con el servicio de radiología para una mejor disposición de pruebas, como la resonancia magnética


The lack of consensus on optimal assessment of disease activity in spondyloarthritis has hampered the development of targeted therapy. Although there are response measures, both for axial and peripheral involvement, such as ASAS, BASDAI or ASDAS, DAS28 or DAPSA, which are principally symptom-based and assess functional status and inflammation but exclude radiographic progression, imaging studies are an important support for more objective assessment of the results. Among them, the techniques that have been shown to be most useful are ultrasound and magnetic resonance. Ultrasound is mainly useful in peripheral involvement (joints, enthesis, dactilitis) to assess inflammation and radiological progression and magnetic resonance to assess mainly axial involvement. Consequently, more training is required for rheumatologists to be self-sufficient in the use of ultrasound, as well as well-established protocols with the radiology service for better provision of tests such as magnetic resonance
