Types of Psoriatic Arthritis and Symptoms
There are several types of
psoriatic arthritis. Symptoms will vary in nature and intensity depending on which type a person has. The major types of psoriatic
arthritis include:
- Asymmetric inflammatory arthritis
- Symmetric arthritis
- Psoriatic spondylitis
- Distal interphalangeal predominant
-
Arthritis mutilans.
It is possible over time for a person to experience more than one type of psoriatic arthritis.
Asymmetric Inflammatory Psoriatic Arthritis
It is estimated that around 50 percent of people with psoriatic arthritis will have this type of arthritis. Some common symptoms with this type of psoriatic arthritis include:
- Joint pain, tenderness, and/or stiffness -- With this type of psoriatic arthritis, joint problems do not occur in the same joints on both sides of the body (e.g., the left knee but not the right knee). The joints that are most often affected are the joints closest to the palm of the hand (known as the proximal interphalangeal joints) and the joints at the ends of the fingertips (the distal interphalangeal joints). The knees, hips, ankles, and wrists are less commonly involved. In most cases, less than five joints are affected.
- Pitting, thickened, and discolored nails.
For this type of
psoriasis, the prognosis is usually good, with only about one in four people developing destructive arthritis and one in three experiencing eye complications. This type of psoriatic arthritis is equally common in men and women.
