REMICADE News and Updates

A diagnosis of psoriatic arthritis can be difficult to make since joint and skin symptoms don’t always occur at the same time. Psoriatic arthritis can develop quickly or slowly over time. At the first sign of symptoms, make an appointment to talk to your doctor. With early diagnosis, you can get started on a plan to relieve pain, preserve your range of motion, and help manage skin symptoms.

If you have psoriasis, you may already be seeing a dermatologist for your condition. Talk to your dermatologist about any arthritic symptoms you may also be experiencing. He or she will be able to make some recommendations for managing both joint and skin symptoms and can discuss treatment options with you. He or she may suggest that you also see a rheumatologist, a doctor who specializes in the treatment of arthritis.

Since the rheumatologist must rule out similar conditions, the diagnosis of psoriatic arthritis works as a process of elimination.  During your physical exam, your physician will look at swollen and tender joints to determine whether you may be at risk for joint damage. If you have joint symptoms along with skin symptoms, such as a rash or irritated, flaky skin, it may also help the rheumatologist rule out other conditions.

To confirm the diagnosis, other tests may be performed, such as:

• Tests such as X-rays or MRI (magnetic resonance imaging) of affected joints
• Blood tests that may or may not reveal a rheumatoid factor (The rheumatoid factor is usually negative in people with psoriatic arthritis.)
• A skin sample to test for the presence of psoriasis
