What is Psoriatic Arthritis?

Psoriasis is non-contagious skin disease caused by abnormal functioning of the body’s immune system; when psoriasis enters the joints and results in inflammation, it is known as psoriatic arthritis (PSA).

It is estimated that approximately 5% or more of psoriasis sufferers have PSA; 70% of patients experienced psoriasis prior to onset of PSA.

The disease shares some features with other joint diseases and inflammatory conditions, such as spondyloarthropathy and rheumatoid arthritis, but is clinically recognized as a separate and distinct disease on its own.

PSA symptoms vary in severity and location, and must be managed with various treatments.

  • PSA is chronic, meaning it is often persistent and long-lasting, but is often episodic providing no predictability of possible periods of relapse or remission.
  • PSA is systemic, meaning it affects many of the body’s systems (joints, musculoskeletal, eyes).

There is no known cure for psoriatic arthritis, but early diagnosis and treatment can slow or prevent permanent damage to the joints.
