Psoriatic arthritis affects many people

People who suffer from psoriasis or have a family history of this skin condition may be at risk for psoriatic arthritis, a serious disease that causes extensive swelling and joint pain.

The Psoriasis and Psoriatic Arthritis Education Center notes that up to 30 percent of people with psoriasis also develop psoriatic arthritis. Psoriasis is an auto-immune skin condition in which the skin reproduces cells at an accelerated rate. This causes patches of flaky, irritated skin, also known as plaques. Psoriatic arthritis can develop at any time, but it is common between the ages of 30 and 50. Environmental factors, genes and immune system responses play a role in the onset of the disease. Patients with psoriatic arthritis can develop inflammation of their tendons, cartilage, eyes, lung lining, and sometimes aorta.

Psoriasis and psoriatic arthritis do not necessarily occur at the same time. Psoriasis generally comes first and then is followed by the joint disease. The skin ailment precedes the arthritis in nearly 80 percent of patients. Psoriatic arthritis is a rheumatic disease that can affect body tissues as well as joints. Psoriatic arthritis shares many features with several other arthritic conditions, such as ankylosing spondylitis, reactive arthritis and arthritis associated with Crohns disease and ulcerative colitis.

The rate of onset of psoriatic arthritis varies among people. For some it can develop slowly with mild symptoms. Others find it comes on quickly and is severe. Symptoms of the disease also vary, but may include the following;

* generalized fatigue

* swollen fingers and toes

* stiffness, pain, throbbing, swelling, and tenderness in joints

* reduced range of motion

* changes in fingernails

* redness and pain of the eyes
