ABSTRACT

Introduction: psoriasis is a chronic, systemic and inflammatory disorder that can evolve to psoriatic arthritis in 5-30% of patients and whose damage is found at the enthesis level, however, little is known about the prevalence of enthesitis in patients with psoriasis without arthropathy.
Material and methods: We performed an observational, prospective, cross-sectional, case-control study of patients with psoriasis and onychopathy vs. psoriasis without onycopathy. For their analysis, they were divided into two groups and an ultrasonographic soft tissue study was carried out at the distal interphalangeal joint of the ten nails. A descriptive analysis was performed.
Results: We included 200 joints, 100 cases and 100 controls. A prevalence of 33.3% of enthesopathy was found for both groups, with 73% (p = 0.019) predominating in the group with onychopathy. The main enthesopathy detected was hyperostosis in 61.7%, while the main onychopathy was the ungueal pits in 33.3%. There was no association between the presence of onychopathy and enthesopathy (p = 0.2).
Conclusions: the prevalence of distal interphalangeal enthesitis is higher in patiens with psoriasis and onychopathy vs. without onychopathy.
