Psoriasis is a common, chronic, immune-mediated disease manifested in the skin, affecting 2-3% of the population. It appears in early adulthood and is a lifelong condition. Up to 90% of all psoriasis patients have plaque psoriasis, which is characterized by “plaques” of the skin, that are mainly found on the scalp, knees, elbows, trunk, and limbs causing itching and pain. Psoriasis is diagnosed by medical examination and can upon diagnosis be treated accordingly. The first in line treatments include topical corticosteroids, while severe cases may receive biologics and oral treatments.
THE MEDICAL NEED FOR BIOMARKERS IN PSORIASIS
There is a need for biomarkers in psoriasis to improve diagnosis, determine disease severity, predict psoriasis development, and track therapeutic response. All of this will lead to improvement of patient management and reduce clinical trial size and length when developing new efficacious treatments.
Psoriasis is characterized as a dermatological disease where the tissue architecture is being remodeled. The main component of the skin is collagens, which are remodeled as a part of normal homeostasis of the skin. In psoriasis, there is an imbalance of tissue build up and tissue break down, resulting in a net degradation of the tissue.Protein fingerprint biomarkers can quantify skin tissue turnover directly in a serum sample and serve as a liquid biopsy.
