Within the module “Bioanalytics”, blood and skin smears are taken from those patients who declare their consent to this. Biosamples are taken at the beginning and end of the study, as well as additional small skin biopsies before and after the initiation of a new systemic treatment.
On these samples, the genetic basis of atopic dermatitis as well as the different response to certain forms of systemic treatment and the development of the bacterial colonisation of the skin (“microbiome”) are examined in anonymised form.
The knowledge gained from this can contribute to a better understanding of the disease, to improve treatments and to develop preventive strategies. In this way, registry patients can substantially contribute to the control the disease.
Participation in this module is voluntary for recruting sites as well as for enrolled registry patients and it is based on additional informed consent.
