- Psoriatic Arthritis (PsA) is a disease that combines the sore, swollen joints of Arthritis with Psoriasis.
- It is a form of Arthritis that affects some people with Psoriasis (a condition that highlights red patches of skin coated with silvery scales).
- In most people, Psoriasis develop first and are later diagnosed with Psoriatic Arthritis, but joint problems can sometimes occur before skin patches appear.
- Stiffness, Joint Pain, and Swelling are the main signs and symptoms of Psoriatic Arthritis.
- Psoriatic Arthritis (PsA) can affect any part of the body, including the fingertips and spine, ranging from relatively mild to severe.
- In both Psoriasis and Psoriatic Arthritis, disease flashes may alternate with periods of remission.
- There is no permanent cure for Psoriatic Arthritis, so the main focus is on controlling symptoms and preventing damage to the joints.
- Without treatment, Psoriatic Arthritis may be disabling.
Types of Psoriatic Arthritis (PsA) are as follows:
This type of Psoriatic Arthritis (PsA) affects the same joints on both sides of the body, so both the right and left knees. Symptoms can be similar to those of Rheumatoid Arthritis (RA).
Symmetric PsA tends to be milder and cause less joint deformity than RA. However, symmetric PsA can be disabling. About half of people with Psoriatic Arthritis (PsA) have Symmetric PsA.
Asymmetric PsA affects a joint or joints on one side of the body. The joints may feel sore and turn red. Asymmetric PsA is generally mild. It affects about 35% of people with Psoriatic Arthritis (PsA).
Distal Interphalangeal Predominant PsA:
This type involves the joints closest to the nails. These are known as the distal joints. It occurs in about 10% of people with Psoriatic Arthritis (PsA).
This type of PsA involves the spine. The intact spine from the neck to the lower back may be affected. Spondylitis PsA can make movement very painful. The hands, feet, legs, arms, and hips may also be affected.
Psoriatic Arthritis Mutilans:
Psoriatic Arthritis Mutilans is a severe, deforming type of PsA. About 5% of people with Psoriatic Arthritis (PsA) have this type. Psoriatic Arthritis Mutilans usually affects the hands and feet. It can also cause pain in the neck and lower back.
