Anti-Interleukin-17s for successful management of pustular psoriasis

Generalised pustular psoriasis (GPP) and acrodermatitis continua of Hallopeau (ACH) are two rare entities included in the spectrum of pustular psoriasis (PP). Due to the lack of randomised controlled clinical trials and standardized guidelines, their treatment remains a challenge for clinicians. Thus, herein we report our centre experience with the successful use of interleukin (IL)-17 inhibitors in three patients affected by PP. We also provide a brief overview of the current knowledge concerning the role of IL-17 in PP pathogenesis and of the use of IL-17 inhibitors in the treatment of PP. Based on our experience, anti-IL-17 molecules may represent a valuable therapeutical option for patients affected by different PP subtypes.
