Adult atopic dermatitis: new and emerging therapies

Introduction: Adult atopic dermatitis (AD) is very difficult to manage. Indeed, AD in adults is frequently refractory to topical treatment, especially with regards to the persistent form. Therefore, long-term treatment with oral immunosuppressive therapy is often required to control the burden of the disease, prevent ?are-ups and achieve better patient quality of life outcomes.

Areas covered: In the last decade the better understanding of AD pathogenesis has been used to improve treatment strategies with many emerging therapeutics options. Epidermal barrier impairment often plays the initial role in the initiation of the disease. Moreover, T helper 2 cytokines interleukin (IL)-4 and IL-13 and their downstream effects are prominent in AD, with pleiotropic effects on the innate and adaptive immune system. Targeting these cells, their products or receptors appears to be a reasonable therapeutic strategy.

Expert commentary: In the next years, many therapeutic options for adult AD will be available. Clinical trials showed that JAK inhibitors, PDE-4 inhibitors and monoclonal antibodies against some IL (IL-4, IL 13, IL-17, IL-22, IL-31) seem to be the most promising drugs, but dermatologists will have to evaluate their effectiveness and safety in clinical practice.
