Psoriasis

What is Psoriasis?

Psoriasis is a chronic inflammatory skin condition characterised by more rapid production of skin cells. This results in a build-up of skin cells on the skin surface, and presents as red and scaly patches. Psoriasis can manifest anywhere on the body and may be associated with other health conditions. 

Causes of Psoriasis

The exact cause of psoriasis is not fully understood, but it is believed to be linked to a combination of genetic and environmental factors. Common triggers and contributors include:

  • Genetics: A family history of psoriasis is a significant risk factor. Certain genes have been associated with an increased susceptibility to the condition.

  • Immune System Dysregulation

  • Environmental Triggers: Certain factors such as infections, stress, and medications can exacerbate or trigger psoriasis flares in susceptible individuals.

  • Skin Injuries or Trauma: Physical trauma to the skin, such as cuts, burns, or insect bites, can lead to the development of psoriasis at the site of injury, a phenomenon known as the Koebner phenomenon.

Treatment Options for Psoriasis

  1. Topical Treatments: Prescription creams and ointments, including corticosteroids, vitamin D analogues, and tar preparations, can be applied directly to affected areas.

  2. Phototherapy: Controlled exposure to narrow band UVB light can be effective for the treatment of psoriasis and is offered at dermatology practices

  3. Systemic Medications: Oral or injectable medications that affect the immune system are used for moderate to severe psoriasis cases.

  4. Biologics: These medications target specific immune system pathways to reduce inflammation and psoriasis symptoms. Given their expense, in Australia there is a requirement by the pharmaceutical benefits scheme for patients to have tried other more common systemic treatments before these can be offered.

  5. Moisturisers: Regular use of moisturisers can help rehydrate the dry skin associated with psoriasis.

  6. Supportive Therapies: Support groups and counselling can provide emotional and psychological support for individuals living with psoriasis.

While psoriasis is a chronic condition with no known cure, effective management can control symptoms and improve the quality of life for those affected.
