Adjunctive Management of Itch in Atopic Dermatitis.

Itch, or pruritus, is a hallmark feature of atopic dermatitis (AD). The impact of AD-related pruritus can range from mildly distressing or distracting to completely disabling. Traditionally, management of itch in AD patients has focused on restoring the altered skin barrier with topical emollients and/or reducing inflammation. A growing emphasis has been placed on directly targeting the neural transmission pathways that mediate itch signaling. Off-label use of neuromodulatory agents has helped reduce this aggravating symptom in atopic patients. This article reviews the current literature on the use of neuromodulatory agents and nonpharmacologic alternative therapies used to treat AD-related pruritus.

Itch in Atopic Dermatitis Management.

Patients with atopic dermatitis (AD) suffer from chronic inflammatory dermatitis and antihistamine-resistant itch. The management of intractable pruritus in AD is important, requiring the development of new therapeutic approaches. At present, the standard treatments for AD include topical anti-inflammatory drugs such as calcineurin inhibitors and corticosteroids. Topical emollient treatment is recommended to moisten the skin and to restore and maintain barrier function. Phototherapy is also effective in reducing the number of epidermal nerve fibers, normalizing imbalances in the levels of expression of axon guidance molecules, and inhibiting pruritus. Systemic treatments such as cyclosporine A and aprepitant are used to treat severe and intractable pruritus in AD. Clinical trials of dupilumab and CIM331 have displayed a significant reduction of pruritus in patients with AD. New antipruritic approaches are targeted to the central nervous system such as spinal interneurons and glial cells. This chapter describes therapeutic approaches for attenuating intractable itch in AD.

Topical therapies for pruritus.

Itch, or pruritus, is the predominant symptom associated with acute and chronic cutaneous disease, and in some cases may be debilitating. To date, there is no single universally effective anti-itch treatment. Because the pathophysiology of itch in most cutaneous or systemic disorders remains unclear, antipruritic therapy is often directed against a variety of targets, including the epidermal barrier, immune system, or the nervous system. Topical therapy is the mainstay of dermatologic management of acute or localized itch or in patients with contraindications to systemic therapies. This review will summarize current topical therapies to treat pruritus and discuss potential future therapies.

Traitements topiques et photothérapie dans la dermatite atopique: Topical treatments and phototherapy in atopic dermatitis.

Atopic dermatitis is a chronic disease with an alteration of the skin barrier and an abnormal immune response. The European guidelines for treatment of atopic dermatitis in children and adults recommend basic hygiene rules including daily use of emollient. Then in the first therapeutic line, for mild or acute atopic dermatitis, the prescription of local care by topical corticosteroids or topical calcineurin inhibitors is recommended. A proactive treatment is now recommended. If the atopic dermatitis is moderate or recurrent, the use of phototherapy in addition to topical treatment is recommended. Each therapeutic step can be added to improve the lesions and reduce the burden of the disease on the patient's daily life. © 2019 Elsevier Masson SAS. All rights reserved.

Long-Term Treatment of Atopic Dermatitis.

Many patients with mild to moderate atopic dermatitis (AD) are managed by identifying and avoiding allergens and irritants, ensuring skin moisturization, and graded use of topical corticosteroids and/or calcineurin inhibitors. There is little consensus on the next step. Most systemic therapies are "off label" in the United States and include phototherapy, cyclosporine, mycophenolic acid precursors, azathioprine, and methotrexate. The decision to use these therapies should be based on efficacy and safety readouts from well designed, long-term trials. This article reviews the long-term randomized, controlled trials examining safety and/or efficacy of interventions recommended for patients with mild to severe AD.
