Ultrasound can be usefully integrated with the clinical assessment of nail and enthesis involvement in psoriasis and psoriatic arthritis

J Clin Med. 2022 Oct 26;11(21):6296
  • Il presente studio ha valutato e comparato i segni ecografici delle unghie e delle entesi nei pazienti con psoriasi ed artrite psoriasica.
  • I pazienti con artrite psoriasica hanno mostrato maggiori tassi di entesopatia degli arti inferiori, con significative differenze nello spessore del legamento patellare distale e del tendine d’Achille. I segni ungueali, invece, sono risultati più severi nei pazienti con psoriasi.



This study aimed to examine and compare the findings of nail and enthesis ultrasonography in patients with psoriasis and psoriatic arthritis.


We identified 154 patients with psoriatic arthritis and 35 patients with psoriasis who were treated at Chang Gung Memorial Hospital, Taiwan, between September 2018 and January 2019.


There were significant differences in the Nail Psoriasis Severity Index scores and Glasgow Ultrasound Enthesitis Scoring System scores between patients with psoriasis and those with psoriatic arthritis. B-mode ultrasonography revealed that onychopathic changes were more common in the psoriasis group. The psoriatic arthritis group showed a higher proportion of lower-limb enthesopathy, with significant differences in distal patellar ligament thickness and Achilles tendon thickness.

Conclusions and perspectives

The findings of nail ultrasonography were more severe in psoriasis cases, and the ultrasonographic findings of enthesopathy of the lower limb were more severe in cases of psoriatic arthritis.
