Psoriatic Arthritis ( PsA)

is a type of chronic inflammatory arthritis that affects people who have psoriasis‐ a skin condition that causes redness and irritation. Psoriasis affects 1‐3% of the population and arthritis can be seen in up to 40% of patients with psoriasis, making this one of the most prevalent forms of arthritis. Most people develop psoriasis first and are later diagnosed with psoriatic arthritis; however, they can occur concurrently and sometimes the joint problems can begin before skin lesions appear.

Psoriatic arthritis occurs when the body's immune system begins to attack healthy cells and tissue. The abnormal immune response causes inflammation in the joints as well as overproduction of skin cells. Joint pain, stiffness and swelling are the main symptoms of psoriatic arthritis. In both psoriasis and psoriatic arthritis, disease flares may alternate with periods of remission.

It's not entirely clear why the immune system turns on healthy tissue, but it seems likely that both genetic and environmental factors play a role. Many people with psoriatic arthritis have a family history of either psoriasis or psoriatic arthritis.

Treatment for psoriatic arthritis is best directed by a rheumatologist; however, many patients require co‐management by a dermatologist. There is no cure for psoriatic arthritis; therefore the focus of treatment is on controlling symptoms and preventing damage to the joints. Without proper treatment, psoriatic arthritis may be disabling.

Symptoms of Psoriatic Arthritis

The onset of symptoms may be gradual and subtle for some patients and sudden and dramatic for others. Generally, the signs and symptoms of psoriatic arthritis include the following:
  • Discomfort, stiffness, pain, throbbing, swelling, or tenderness in one or more joints
  • Reduced range of motion in joints
  • Tenderness where muscles or ligaments attach to bones, particularly the heel and bottom of the foot
  • Inflammation or stiffness in the lower back
  • Nail changes such as separating from the nail bed, or becoming pitted or infected‐looking
  • Morning stiffness
  • General fatigue
  • Redness and pain in tissues surrounding the eyes
