Management of congenital ichthyoses: guidelines of care: Part two: 2024 update.

Abstract

In 2019, a group of experts published the first European guidelines for the management of congenital ichthyoses after a multidisciplinary expert meeting held in 2016. An update of these guidelines and literature search was planned every 5 years, given the clinical, molecular and therapeutic advances, including the use of biologic therapies. We present here updated guidelines that have been developed by a reorganized multidisciplinary group of international experts after a systematic review of recent literature, discussions and consensus reached at an expert conference held in June 2023. The guidelines provide summarized evidence and expert-based recommendations that aim to guide clinicians in the management of these rare and often complex diseases. These guidelines consist of two sections. Part one is reported elsewhere. Here, Part two covers the management of complications (eye, ear-nose-throat, pruritus, pain, cutaneous infections, vaccinations, growth failure and nutritional deficiency, hair and nail anomalies, reaction to hot and cold climates, physical limitations, comorbidities) and the particularities of the neonatal period and Netherton syndrome.
