Reactive arthritis is a type of arthritis that develops in response to an infection elsewhere in the body. Most often, this infection has occurred in the digestive tract or urogenital tract. Reactive arthritis can cause inflammation of the urinary tract, the joints, and the eyes. Treatment methods include one of several different kinds of medication (see Reactive Arthritis Treatment).
Up to 8 percent of people who have psoriasis (a skin condition that is characterized by scaling and swelling) develop psoriatic arthritis. In a person with psoriatic arthritis, the joints (and sometimes other areas of the body) become inflamed. Joint pain and tenderness do not occur as often with psoriatic arthritis as they do with other types of arthritis (see Psoriatic Arthritis Symptoms). Psoriatic arthritis treatment can involve lifestyle changes, medications, and routine monitoring and ongoing care. Psoriatic arthritis affects about 160,000 Americans.
Enteropathic arthritis is a form of arthritis (joint inflammation) associated with inflammatory bowel disease (IBD) -- the two most common forms of IBD being Crohn's disease and ulcerative colitis. Up to 20 percent of people with Crohn's disease and ulcerative colitis will develop enteropathic arthritis. Ten percent to 20 percent will develop enteropathic arthritis within the knees, hips, ankles, elbows, or wrists. These joints are known as peripheral joints. About 5 percent will develop enteropathic arthritis in the spine.
It is possible that enteropathic arthritis symptoms may occur before a person is even diagnosed with inflammatory bowel disease.
