    Earlier diagnosis of psoriatic arthritis will prevent disease progression

    Treatments like biologics help to ward off adverse impacts of the condition


    New care model

    Dr. Eder is currently involved in a pilot study of an innovative model of care where patients with psoriasis experiencing musculoskeletal symptoms, such as joint pain and stiffness, have direct access to rheumatology care. The model includes a central triage clinic where these patients are screened by other healthcare professionals, such as physiotherapists, and undergo a targeted ultrasound of symptomatic joints to assess if there are any signs of active arthritis.

    “We anticipate that this new model of care will improve the early detection of psoriatic arthritis among patients with psoriasis,” Dr. Eder says.

    Some of the immunological pathways that are important in rheumatoid arthritis do not play a role in psoriatic arthritis, Dr. Eder says.

    “Pathways involving IL-17 and IL-23 are more important in psoriatic arthritis but less important in rheumatoid arthritis,” she says.

    Dr. Eder reports no relevant financial relationships.
