Arthritis - psoriaticDefinition Return to top
Psoriatic arthritis is an arthritis that is often associated with psoriasis of the skin.
Causes Return to top
Psoriasis is a common, chronic skin condition that causes red patches on the body. About 1 in 20 individuals with psoriasis will develop arthritis along with the skin condition. In the majority of cases, psoriasis comes before the arthritis.
The arthritis may be generally mild and involve only a few joints. In a few people, the disease may be severe and affect many joints, including the spine. When the spine is affected, the symptoms are very much like those of ankylosing spondylitis.
The cause of psoriatic arthritis is not known, but your genes may play a role. In general, people who have psoriasis have a higher rate of arthritis than the general population.
Symptoms Return to top
Exams and Tests Return to top
During a physical examination, the doctor will identify skin lesions, tenderness, and swelling of joints. Joint x-rays may be performed.
Treatment Return to top
Your doctor may prescribe nonsteroidal anti-inflammatory drugs (NSAIDS) or salicylates to reduce pain and inflammation of the joints.
More severe arthritis requires treatment with more powerful drugs called disease-modifying antirheumatic drugs (DMARDS) such as:
New medications that block an inflammatory protein called tumor necrosis factor (TNF) are becoming the treatment of choice. These include:
Occasionally, particularly painful joints may be injected with steroid medications.
In rare cases, surgery to repair or replace damaged joints is needed.
Your doctor may suggest a healthy mix of rest and exercise. Physical therapy may help increase movement of specific joints. You may also use heat and cold therapy.
Outlook (Prognosis) Return to top
The course of the disease is often mild and affects only a few joints. In those with severe arthritis, treatment is usually very successful in relieving the pain.
Possible Complications Return to top
Repeated episodes may occur.
When to Contact a Medical Professional Return to top
Call for an appointment with your health care provider if arthritis symptoms develop along with psoriasis.
