Systemic immunosup- pressive treatments may be required for a minority of patients with recalcitrant severe disease. The strongest evidence for efficacy in patients with severe AD was obtained for cyclosporine A (CsA) (3), which is the only approved immunosuppressive treatment for this indica- tion in Europe (4, 5). As novel biologic treatments are currently undergoing development for use in AD (6), it is of utmost importance to evaluate the effectiveness of CsA in a real-life setting in order to obtain a clear picture of the unmet needs in patients with severe AD. Drug survival is the time patients remain on a specific drug (7). Performing drug survival studies with chronic diseases in a real-life setting is a way of assessing long- term drug effectiveness and safety. However, only one study has reported drug survival data for CsA in a long- term daily practice cohort of adult patients with AD (8). As the outcomes of drug survival studies may be influenced by specific behaviours of physicians and patients, it is important to replicate this study in other settings in order to establish the more general relevance of the findings. The aim of the current study was to perform a detailed analysis of CsA modaliti
