ABSTRACT
Objetivo. Describir una serie amplia de pacientes con artritis mutilante/resortiva (AM) de una población representativa de pacientes con artritis psoriásica (APs) y analizar las variables asociadas. Métodos. Estudio transversal multicéntrico que incluyó de forma consecutiva a los pacientes afectados de APs de 8 centros. A aquellos pacientes con tumefacción o deformidad de manos o pies sospechosa de se les realizó una radiografía antero-posterior. Se consideró que el paciente estaba afectado de AM si presentaba un trastorno erosivo que afectaba totalmente ambas superficies articulares. Resultados. De los 360 pacientes con APs estudiados, 24 presentaban AM (6,7%). La duración de la enfermedad fue significativamente mayor y presentaban una peor capacidad funcional, así como una mayor afección de IFD (p<0,05). En un 30% se detectaron cambios radiológicos indistinguibles de una osteoartritis nodular. Conclusiones. La AM en la APs se asocia a una peor capacidad funcional. Su posible asociación con la osteoartritis nodular de manos merece más estudios (AU)
Objective: To describe a large series of patients with mutilans/resorptive arthritis (AM) of a representative population of patients with psoriatic arthritis (PsA) and analyze the associated variables. Methods: Multicenter cross-sectional study of consecutive patients affected by PsA in 8 centers. In patients with swelling or deformity of the hands or feet we performed an anteroposterior rx. The patient was affected by AM if erosive disorder affecting both articular surfaces completely was present. Results: Of the 360 patients studied, 24 had PsA and AM (6.7%). The duration of their disease was significantly higher, and they exhibited a worse functional capacity as well as more DIP joint affection (P<.05). 30% had radiological changes indistinguishable from nodular osteoarthritis. Conclusions: AM in PA is associated with a worse functional capacity. Its possible association with nodular hand osteoarthritis deserves further study (AU)
