Psoriasis is a chronic, scaly rash that affects people of all ages.* It is influenced by genetics and environmental factors.* It is not contagious. The condition can be very socially disabling, and commonly leads to depression.* It can also be associated with other internal health problems, including psoriatic arthritis.*
While there is no cure for psoriasis, recent advances in treatment mean that the great majority of cases can be well controlled.*
Treatments available include:
- Topical Agents: These include emollients (sometimes with additives like tar and salicylic acid), and prescription treatments including topical corticosteroids, calcipotriol, and topical retinoids.* These are usually all that is needed to control mild psoriasis, and they can be combined with treatments below for more severe psoriasis.*
- Intralesional Kenalog (ILK) Injection: Psoriatic plaques that fail to respond to topical therapy may be improved by administration of intralesional corticosteroid injections.* Triamcinolone (Kenalog) is often used for this purpose.* The agent is injected directly into the dermis of a small, persistent plaque. The concentration is generally 3 to 10 mg per mL, depending on the size, thickness and area of the lesion.* The dose of triamcinolone is released gradually over three to four weeks; additional injections may be needed every four to six weeks to improve the response.* Disadvantages of intralesional injections include pain during the injection and potential side effects of local atrophy and systemic absorption.*
