MedicalResearch.com: What is the background for this study? What is the importance of differentiating these two skin conditions?
Response: The background is that up to now skin biopsies were considered the gold standard for obtaining skin biomarkers of atopic dermatitis/AD and psoriasis that are linked to disease activity in skin and for obtaining the cutaneous gene and protein expression fingerprint of each individual disease. Biopsies are also used in clinical trials to obtain the skin phenotype. However biopsies are invasive, painful and scarring. Thus we need less invasive means to profile diseases and obtain biomarkers. Tape strips is a minimally invasive approach to sample and study the skin. However, prior studies using tape strips could not fully capture the phenotype of the diseases and also sampling the recovery rate was less than optimal, not allowing this approach to be widely used. Psoriasis and AD are the most common inflammatory skin diseases, but these diseases are treated very differently and in some cases are very difficult to differentiate between them clinically and even in biopsies.
