Psoriatic Arthritis
Overview
Psoriatic arthritis is a type of inflammatory arthritis associated with psoriasis, a condition characterized by chronic skin scaling and nail changes. Doctors have identified several forms of psoriatic arthritis. Some patients experience symptoms in the small joints of the fingers and toes, while others have symptoms in joints on only one side of the body.
Symptoms and Types
In some cases, larger joints on both sides of the body may be affected, similar to rheumatoid arthritis. Some individuals experience arthritis symptoms in the back and spine, and in rare cases, known as psoriatic arthritis mutilans, the disease can severely damage the joints and bones. Often, psoriasis symptoms precede arthritis symptoms, with changes in the fingernails serving as a potential indicator. Most people develop psoriatic arthritis between the ages of 35-45, though it can occur in both adults and children.
Prevalence and Causes
The exact prevalence of psoriatic arthritis remains unclear. Recent studies suggest it affects about 1 in 5 people with psoriasis. The cause is also unknown, but genetic factors seem to play a role. People with psoriatic arthritis are more likely to have relatives with psoriasis or the same joint disease. Researchers believe that genes on chromosomes 6p and 17 may increase susceptibility, although no specific genetic abnormality has been identified. Psoriatic arthritis is thought to be an autoimmune disorder, where the body's immune system mistakenly attacks its own tissues.
Symptoms and Diagnosis
Typical symptoms include dry, scaly skin patches, joint pain, and changes in the hands, feet, knees, and spine. Tendon pain and nail deformities are also common. A blood test for rheumatoid factor, which indicates rheumatoid arthritis, is usually negative in psoriatic arthritis patients. X-rays may reveal damage to larger joints and fusion of the joints in the fingers and toes.
Treatment
Treatment aims to manage both psoriasis skin lesions and arthritis inflammation. Standard arthritis medications like nonsteroidal anti-inflammatory drugs, gold salts, and sulfasalazine are ineffective for psoriasis. Antimalarial drugs and systemic corticosteroids should be avoided, as they can worsen psoriasis if stopped abruptly. Some treatments can benefit both the skin lesions and the inflammation associated with psoriatic arthritis.
This comprehensive approach helps manage symptoms and improve the quality of life for those affected by psoriatic arthritis.
