RESUMO
Chronic prurigo is an inflammatory dermatosis defined by the presence of chronic pruritus and single to multiple symmetrically distributed pruriginous lesions such as nodules, papules, and plaques. Various dermatological, systemic, neurological, and/or psychiatric diseases are associated with chronic prurigo. The care of these patients is very complex due to the multifactorial character and also because of the sometimes very pronounced consequences such as an impairment of quality of life with sleep disorders. Furthermore, there are no approved therapies. The current guideline-based treatment recommendations include topical application of steroids, capsaicin, calcineurin inhibitors, phototherapy, and systemic use of gabapentinoids, µopioid receptor antagonists, immunosuppressants, or dupilumab. Results from randomized controlled trials and case series on new therapies including biologics (e.g., nemolizumab) and Janus kinase inhibitors are promising. This article provides an overview of currently available treatment options and discusses the latest data on the efficacy of future therapies.
