Psoriatic Arthritis (PsA)

  • About PsA

    What is psoriatic arthritis(PsA)? 1

    • Psoriatic arthritis is a form of joint inflammation affecting individuals with psoriasis. Approximately one-third of patients with psoriasis will eventually develop psoriatic arthritis.

      In most cases, the arthritis will develop after the appearance of psoriasis. However, some patients do develop the arthritis before they notice any psoriasis on their skin.

    What parts of the body does it affect? 2

    • Psoriatic arthritis can affect your fingers, nails, spine, feet, eyes(uveitis) and/or neck.

  • Diagnosis

    How is it diagnosed? 1,3

    It is important to diagnose PsA early to begin appropriate treatment and to prevent any unnecessary joint damage occurring.
    Delay in diagnoses of 6 - 12 months have been shown to impact on long-term joint damage and functional disability.

    A review of patient’s medical history, symptoms, and blood tests to rule out certain other conditions is needed. Absence of rheumatoid factor in the blood often helps to distinguish psoriatic arthritis from rheumatoid arthritis.

    So if you experience any aches and pains, be sure to tell your doctor. They may then cross refer you to a rheumatologist for further assessment and treatment.

  • Treatment

    How is psoriatic arthritis treated? 4,5

    There are many different treatments available for psoriatic arthritis, depending on the type and severity.
    A doctor or other health care provider can offer you treatments ranging from exercises and physical supports to tablet and injection medications to reduce the pain and inflammation as well as slow down the progression of the arthritis.

    What are the treatment options? 4,5

    NSAIDs, DMARDs, Immunosuppressants, biologics, oral medications, corticosteroids and etc.
