Psoriasis

Psoriasis is a chronic autoimmune skin condition characterized by symptoms such as dry skin scales, redness, itching and inflammation caused by rapid multiplication of skin cells.

The exact etiology of psoriasis remains unclear, although genetic predisposition and immune system dysfunction plays an important role in psoriasis development.

Psoriasis often follows an unpredictable pattern of flare-ups and may be influenced by various external triggers such as mild trauma, sunburn, infections, systemic drugs and stress.

In some individuals, psoriasis may also be associated with conditions such as arthritis, cardiovascular diseases, metabolic syndrome, inflammatory bowel disease and depression.

The diagnosis of psoriasis is usually based on the presence of typical skin lesions. There are no special blood tests or diagnostic procedures used for psoriasis diagnosis.

Psoriasis treatment mainly focuses on controlling symptoms and achieving long-term remission. Common approaches include:

  • Topical therapies: Corticosteroids, vitamin D analogues, clinically proven oil for psoriasis, psoriasis creams, coal tar and moisturizers.

  • Systemic therapies: Methotrexate, cyclosporine, acitretin and biologics used in psoriasis treatment.
  • Phototherapy: Controlled ultraviolet (UV) light treatment for psoriasis.
  • A combination of these psoriasis treatment methods is often used to reduce symptoms, joint pain and other associated complication
