Psoriasis Symptom Inventory (PSI) as a patient-reported outcome in mild psoriasis: Real life data from a large psoriatic arthritis registry.

Objective: Our aim is to test the validity of the Psoriasis Symptom Inventory (PSI), a patient-reported outcome, to assess the psoriasis severity within the scope of rheumatology.

Methods: Within the PsA international database (PSART-ID), 571 patients had PSI, while 322 of these also showed body surface area (BSA). Correlations between PSI, BSA, and other patient- and physician-reported outcomes were investigated.

The Relationship Between Physical Examination and Ultrasonography of Large Entheses of the Achilles Tendon and Patellar Tendon Origin.

Objective: To investigate the relationship between physical examination (PE) and sonographic features of enthesitis, based on anatomical sites.

Methods: The analysis was done using merged raw data of 3 studies on 2298 entheses.

Results: Patients with clinical Achilles enthesitis had more abnormalities on ultrasound (US): hypoechogenicity, p < 0.

Greater magnitude of entheseal microdamage and repair in psoriatic arthritis compared with ankylosing spondylitis on ultrasound.

Objectives: AS and PsA share clinical and immunological features centred on enthesitis. However, a strong association between PsA and preceding injury has been recognized. The aim of this study was to test the hypothesis that the entheseal damage seen by US is commoner in PsA patients than in AS patients.

Axial psoriatic arthritis: the impact of underdiagnosed disease on outcomes in real life.

Psoriatic arthritis (PsA) may affect different joints, including the spine. The prevalence of spinal involvement is variable depending on the definition and a subset of patients have been identified in cohorts that do not have clinical features of axial disease and yet have imaging findings. Still, there is not a consensus on how and when to screen axial disease.
