Establishment of novel biomarkers for Personalized medication for atopic dermatitis].

To diagnose atopic dermatitis (AD), an appearance of eczema examined by experienced dermatologists is required. Therefore, biomarkers to diagnose AD or to reflect the severity of AD would be of a great use for non-specialists in the clinic or hospitals. We can apply such a biomarker for realization of personalized medicine for AD in the future. Interleukin-4 (IL-4) and IL-13 have been known to play important roles in the pathogenesis of allergic diseases including AD. In addition to these, we previously identified SCCA1, SCCA2, and periostin as IL-4/IL-13-inducible genes. We recently established ELISA systems to measure serum levels of SCCA1, SCCA2, and periostin and evaluated their usefulness in the treatment of AD patients. Serum SCCA1 and SCCA2 are up-regulated in AD patients and can distinguish AD patients from non-atopic controls, and their serum levels reflect eczema grades. Periostin concentration is also elevated in the serum of AD patients. These results demonstrate that SCCA1, SCCA2, and periostin might be promising biomarkers for personalized medicine in allergic diseases including AD.
