This is a low-intervention phase IV trial. The main objective is to optimize the treatment of patients with moderate-severe atopic dermatitis who require systemic treatment.
Primary outcome is the percentage of patients with primary non- response to treatment with cyclosporin. Defined as fail to achieve EASI-75 (a 75% improvement in EASI score) at week 16 of follow-up. A 12-month recruitment period is planned and about of 100 patients with moderate-severe atopic dermatitis will be recruited. The study is divided into two cohorts. All patients diagnosed with moderate-severe atopic dermatitis who are going to receive treatment with cyclosporin in the Dermatology Service of La Paz University Hospital and associated Specialty Centers are selected in cohort 1. Patients will receive the starting dose used in routine clinical practice. All patients diagnosed with moderate-severe atopic dermatitis who are receiving or have received cyclosporin therapy in the Dermatology Service of La Paz University Hospital and associated Specialty Centers are selected in cohort 2.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Start of Cyclosporin treatment | Other | Patients will receive the starting dose used in routine clinical practice (maximum dose of 3 mg/kg/day is standard practice in our center). Once the patient is included in the clinical trial their therapeutic management will be carried out according to usual clinical practice, but additional procedures will be performed:
|
|
| Receiving or received cyclosporin | Other | If the patient is receiving cyclosporine therapy, a blood sample for pharmacogenetic analysis will be obtained at screening; also, at discretion of the treating physician, biological samples will be obtained (blood and urine) in this visit and in the follow-up visits to assess biochemical and kinetic variables. Clinical data (scales) will be collected from clinical records from treatment start until study inclusion and prospectively after study inclusion. If the patient received cyclosporine previously but is no longer under CsA therapy, a blood sample will be extracted at screening for pharmacogenetic analysis. Clinical data (scales) will be collected from clinical records. |

Non-randomized clinical trial. The intervention consists in additional follow-up visits out of usual clinical practice. According to RD 1090/2015 of December 4, which regulates clinical trials with drugs, it is considered a low level intervention clinical.
