Ultrasonographic involvement of the anterior chest wall is frequent in Spondyloarthritis and is associated with disease activity.
New lesions of the anterior chest wall after 5 years of follow up are associated with high disease activity at 5 years.
Anterior chest wall could be a new target to evaluate structural outcome in Spondyloarthritis.

To evaluate, factors associated with new ultrasonographic lesions of the anterior chest wall in spondyloarthritis (SpA) after a follow up of 5 years.


SpA Patients included in 2013 in a first study were evaluated five years later. Ultrasound B mode and power Doppler examination of the two sternoclavicular joints and the manubrio-sternal joint were performed by the same two examinators at baseline and five years later. The presence of erosion, synovitis, ankylosis, power Doppler signal, joint effusion and joint space narrowing were assessed blind of the first evaluation.


Among the 131 patients at baseline, 58 patients were evaluated 5 years later. The mean age was 48.2±11.9 years old, with 86% of male and mainly an axial disease (78%). Patient characteristics are comparable to the original cohort. The most frequent lesions were ankylosis of the manubriosternal joint (38%) and erosions of the sternoclavicular joint (29%). 31 patients (53%) developed a new lesion of the ACW. There is a statistically significant association between new lesions of the ACW and higher ASDAS CRP (1,86±1,07 VS 3,0±2,17 P <0,01) and with CRP (5,34±7,85 VS 16,2±35, P =0,035) in the moment of the examination. There was no baseline factor associated with the structural progression.


The occurrence of new lesions of the anterior chest wall is associated with a higher disease activity and a higher CRP at 5 years.
