What is Psoriasis?

Psoriasis is an autoimmune disease that is characterized by red, itchy scaly patches. The plaques are thick, dry, and discoloured skin. These patches crack sometimes and bleed.

This disease occurs when the immune system attacks healthy cells in the body instead of other infectious germs.

The typical life cycle of a skin cell is one month but in psoriasis the cell production is rapid. Normally, the skin cells are developed deep in the skin and slowly appear on the surface. In psoriasis, the skin cells grow at a faster rate and do not fall off. The accumulation of skin cells leads to plaque formation.

It is commonly present on the scalp, face, elbow, knees, palm, and feet. However, it is not just confined to these areas and can affect any part of the body. Nails, mouth, and genital psoriasis it's less common.

Psoriasis symptoms: Different patients have different symptoms. Symptoms depend upon the type of psoriasis. Patches are either small, present on scale or elbow or extend over a large area of the body.

Common symptoms include:

  • Raised, implement patches of skin that appears red on fair skin whereas it appears purple on dark skin

  • Whitish silver scales or greyscales

  • Cracks on the patches

  • Bleeding plaques

  • Itching and burning

  • Soreness around patches

  • Pitted and thick nails

  • Painful and swollen joints

The course of psoriasis is a cyclic manner. The symptoms increase for a few days to weeks -then clear up and diminish over some time. It means the patient is in remission. After this again the triggers of the condition get severe and may go off completely.

Our expert dermatologist physically examines the skin condition of the patient, asks for detailed history, and makes a diagnosis after the biopsy report. There are various types of treatments for psoriasis.

Topical treatment: Topical ointment, cream, and foams are the first step toward treating psoriasis. Steroid cream decreases immune cells and helps in controlling swelling and redness. Salicylic acid aids to soften scaly patches. Calcipotriol slows down the overactive skin cells, skin specialists may combine it with steroid creams.

Immunosuppressants, coal tar ointments, shampoo, and prescription retinoids are also effective against psoriasis. All the topical treatments should be used as directed by the dermatologist.

Phototherapy: Light therapy can decline the growth of skin cells. It is an in-office procedure done by dermatologists a few times a week. Nowadays at home kids are also available but can be used after a medical prescription.

Types of photo therapies:

Narrowband UVB therapy

Broadband UVB therapy

Excimer laser therapy: Laser therapy is beneficial to control red patches by application of targeted ultraviolet B rays.

Psoralen + UVA therapy: It is also known as PUVA. A drug Psoralen and ultraviolet A light in combination is used. The skin becomes more sensitive to light and boosts the amount of UVA light the skin can absorb.

In long-term use, phototherapy increases the risk of getting skin cancer.

Systemic treatments: In case other treatments fail, systemic therapy is considered to treat moderate to severe psoriasis. It includes immunosuppressants like methotrexate, cyclosporine; enzyme inhibitors such as Apremilast, oral retinoids – Acitretin, etc.

Systematic biologic treatment: It is a newer drug system and makes use of biologics to target specific immune cells or proteins causing psoriasis. Tumour necrosis factor inhibitors (TNF), interleukins (IL)-23 inhibitors, IL-17 inhibitors, and IL-12 inhibitors play an important role in the systemic biologic treatment and do not affect the complete immune system.
