Risk Assessment in Atopic Dermatitis: Guidance from a Multidisciplinary Expert Panel.

Guidelines recommend that patients with severe atopic dematitis (AD) be treated with Janus kinase inhibitors (JAKi). Recently, the safety of JAKi as a class was reviewed by the European Medicines Agency, leading to a modification of the Summaries of Product Characteristics. For upadacitinib, changes involve reduced posology and restriction of its use to patients with no other alternative amongst the elderly and those at an increased risk of major adverse cardiovascular events (MACE), cancer and venous thromboembolism (VTE). Risk assessment may be daunting and clarity regarding definitions and data is needed. An interdisciplinary workshop, termed the Multiple In-treatment Risk Assessment & Management, was conceived to provide dermatologists with a platform for multidisciplinary exchange on risk assessment in patients with MACE, cancer and VTE to correctly recognise patients with increased risk. In this review, we characterised common and less common patient profiles in order to assess the risk. With the cooperation of a cardiologist, oncologist, respiratory medicine specialist and haematologists, we identified the risk factors for MACE, cancer and VTE. The results show that taking a careful medical history is the basis of risk assessment and that a careful medical history should be performed regardless of the intended therapy in AD. We propose that risk levels be used in the general population as a benchmark to evaluate risk levels in patients with AD, and provide a checklist to support such risk assessments in routine clinical practice. Our work provides a clear framework for risk assessment to the community of dermatologists and, therefore, contributes to improving the standard of care in AD.
