Question

Ultrasound entheseal changes in asymptomatic psoriasis without psoriatic arthritis

Answer 1

$\underline\bold{\huge{Answer! !}}$

The inflammatory involvement of the enthesis in the course of psoriasis is accompanied by structural abnormalities detectable by ultrasound. The most common of these abnormalities is the thickening of the tendon at the insertion site. Aims: The aim of the present study was to compare the thickness of entheses of patients with psoriatic arthritis, only skin psoriasis, and healthy controls. Methods: A cross-sectional study was conducted in a cohort of patients affected with either only skin psoriasis or psoriatic arthritis as well as in a control group. Eight entheses sites were scanned by ultrasound bilaterally. The following entheseal characteristics were collected and recorded in a predefined database: entheseal thickness, bone erosions, enthesis calcifications (enthesophytes), presence of blood flow, and presence of bursitis. All the detected entheseal changes were scored, and the data was statistically analyzed.
