[What's new in dermatological treatment?]

The therapeutic revolution in the management of inflammatory dermatoses is under way. The therapeutic arsenal is expanding in the field of psoriasis, including biologics (TNF blockers, anti-IL12/IL23, anti-IL17, and anti-IL23 antibodies), new small molecules (tyrosine kinase inhibitor), and a new biologic for generalized pustular psoriasis (anti-IL36 receptor). New biologics will be soon available in the field of atopic dermatitis in addition to anti-IL4/IL13 antibodies. New targeted treatments of pruritus are also coming (biologics and small molecules). A first randomized placebo-controlled trial has confirmed the interest of JAK inhibitors in alopecia areata. These molecules seem to be also promising in dermatomyositis. Another therapeutic revolution will be technological with the development of new therapeutic agents: small interfering RNA. Recent clinical trials confirmed their efficacy in hereditary amyloidosis.
