BACKGROUND As psoriatic disease (PD) is a condition characterized by the combination of inflammatory skin (psoriasis) and osteo-articular manifestations (psoriatic arthritis), its treatment should cover both its clinical components. OBJECTIVE The objective of this study was to propose a flexible framework for the use of biological agents in PD. METHODS The proposal was drawn up by a group o...

BACKGROUND Peripheral disease (arthritis, enthesitis and dactylitis) and extra-articular disease (uveitis, psoriasis and inflammatory bowel disease) is common in ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA). So far, however, summary data on the prevalence are lacking. The objective of this meta-analysis was to assess the prevalence of peripheral and extra-...

OBJECTIVE To investigate the association between psoriatic arthritis (PsA)-specific clinical composite scores and ultrasound-verified pathology as well as comparison of clinical and ultrasound definitions of remission. METHODS We performed a prospective study on 70 consecutive PsA patients. Clinical assessments included components of Disease Activity Index for Psoriatic Arthritis (DAPSA) and ...

INTRODUCTION Chronic back pain (CBP) is frequently the presenting symptom in patients with suspected axial spondyloarthritis (axSpA).

This study aims to investigate which SpA features increase the likelihood of a positive H...
