Quality of life and its relation to periarticular bone changes in psoriatic patients with or without joint involvement.

Objectives: To assess periarticular bone changes in psoriasis patients with or without joint involvement and its effect on patients' quality of life (QoL).

Methods: This cross-sectional study enrolled 50 patients with psoriasis (25 only with skin psoriasis (PsO) and 25 with psoriatic arthritis (PsA)), as well as 25 healthy controls. All participants were analyzed by high-resolution computed tomography (HR-CT) scans of the dominant hand (second and third metacarpophalangeal joints) for detection of new bone formation (enthesophytes) and erosions.
