Psoriatic arthritis Description | Celltrion Patientenseite

Psoriatic arthritis is a chronic rheumatic disease. But what is different about psoriatic arthritis?

Psoriatic arthritis is a non-infectious, inflammatory autoimmune disease, and a combination of psoriasis and joint inflammation. With its reddish skin thickening and very scaly silvery-white surface, psoriasis is one of the most common skin diseases, but is a so-called systemic disease. This means it is not necessarily limited to the skin; it may affect other regions of the body, such as the joints, as well.

Examples of joints affected by psoriatic arthritis

As well as changes to the skin, psoriatic arthritis often also causes long-lasting inflammation in the joints, which can attack the articular cartilage and bones, and thus cause proliferation of the synovial membrane. Left untreated, the joint will become increasingly damaged, and its mobility limited.

The disease often occurs between the ages of 30 and 55, and usually affects men and women equally. The disease progresses in recurring episodes, i.e. alternating phases with (severe) symptoms and phases with more mild or no symptoms.
