Psoriasis Treatment

Psoriasis is a chronic autoimmune disease that appears on the skin as spots, raised patches, scales, or lesions in a variety of shapes and sizes, and in different locations of the body. It is a condition that triggers the inflammation of T-cells ( a type of white blood cell), which then causes the skin cells to grow faster than normal, and to pile up in raised patches. Though it can look threatening, psoriasis it not contagious.

The five types of psoriasis are plaque (the most common), guttate psoriasis, inverse, pustular, and erythrodermic (the least common) psoriasis. Symptoms common to all the types are itchy, dry, cracking skin; swollen joints; red patches; silvery scales, and even lesions.

Who Gets Psoriasis and Why?

Anyone can develop psoriasis at any time. The following factors are known to increase your risk of developing the condition:

  • Family history
  • Obesity
  • Stress
  • Smoking
  • Medical conditions such as strep infection

Many medical practitioners agree that family history is the most significant of all the risk factors. About one-third of people with psoriasis have at least one family member with the disease.

What Are the Treatment Options?

Topical treatments include over-the-counter ointments and creams containing salicylic acid and tar, and topical steroids.

Phototherapy, or light therapy, is prescribed for a number of different skin conditions. It involves exposing the skin to ultraviolet light in a controlled environment. During PUVA therapy, photoactive substances called psoralens are applied topically or administered orally; exposure of the narrowband UVB in a controlled environment assists in bringing back the pigmentation. We do not offer light therapy, but it is one of the treatment options available.

Systemic therapy is typically used for individuals with moderate to severe psoriasis and psoriatic arthritis. The most common systemic medicines for treating psoriasis are Acitretin (Soriatane), Cyclosporine, and Methotrexate.

Biological drugs, or biologics, are used to treat both psoriasis and psoriatic arthritis. They are protein-based drugs from living cells that target a specific type of immune cell, the T cell, or proteins in the immune system that play a part in the development of psoriasis.
