Psoriatic arthritis (PsA) is a chronic inflammatory disease of the joints, spine
and entheses from a group of spondyloarthritis (SpA), which is usually
observed in patients with psoriasis (Ps). The diagnosis of PsA is based on the
CASPAR criteria for psoriatic arthritis. The disease results from interactions
between genetic, immunological and environmental factors. The main
clinical manifestations of PsA include peripheral arthritis, enthesitis,
dactylitis, and spondylitis. Due to the fact that PsA is a clinically
heterogeneous disease, its activity is assessed using complex indices, by
taking into account that the patient has arthritis, enthesitis, dactylitis, and
spondylitis. The goal of treatment for PsA is to achieve remission or minimal
activity of the main clinical manifestations of the disease
