Disease Analysis: Psoriatic Arthritis

Psoriatic arthritis is grouped with spondyloarthritis and is characterized by inflammation in the spine (spondylitis) and/or joints (arthritis). It is often preceded by a diagnosis of psoriasis by about 10 years. The disease may be characterized by joint pain, swelling, or morning stiffness, and about 80–90% of psoriatic arthritis patients experience nail lesions, which include pitting (dents) and onycholysis (detachment). Around 30% of individuals with psoriasis develop psoriatic arthritis.
