What is neurodermatitis? Interleukin (IL)-31 is involved in the pathogenesis of AD, specifically including the symptom of pruritus. The humanized monoclonal antibody nemolizumab inhibits IL-31 signaling via binding to interleukin-31 receptor A. This phase 2 randomized trial evaluated the safety and efficacy of nemolizumab in patients with AD. The 12-week study included 264 patients with moderateto- severe AD that did not respond to topical agents. Patients were assigned to receive subcutaneous nemolizumab 0.1, 0.5, or 2.0 mg/kg or placebo every 4 weeks. (An exploratory group received nemolizumab 2.0 mg/kg every 8 weeks.) There were 216 study completers. Percentage change on a pruritus visual analog scale in the 4-week treatment groups was -43.7% with the 0.1 mg/kg dose of nemolizumab, -59.8% with the 0.5 mg/kg dose, and -63.1% with the 2.0 mg/kg dose, compared to -20.9% with placebo. Changes on the Eczema Area and Severity Index were -23.0%, -42.3%, -40.9% in the three nemolizumab dose groups compared to -26.6% with placebo. Changes in body surface area affected were -7.5%, -20.0%, -19.4%, and -15.7%, respectively. Treatment discontinuation rate was 13% in the nemolizumab 20 mg/kg dose group and 17% in all other groups. At all monthly doses studied, nemolizumab reduced pruritus scores in patients with moderate to severe AD. The study supports an approach targeting IL-31 receptor A in patients with AD. Within its limitations, the study suggests that a nemolizumab dose of 0.5 mg/kg every 4 weeks provides the best risk-benefit profile. Mayo Clinic does not endorse companies or products.

Bruijnzeel-Koomen CA The typical localization of lesions in this age is antecubital fossae, hand dorsum and wrist joint region, popliteal fossae and ankle area, parotid folds, neck, torso. Neurodermatitis has a typical morphological element, it is papule, an appearance of which severe pruritus is preceded. Due to the grouping of papules skin in the folds becomes infiltrated with the pronounced intensification of a picture (lichenification). Color of foci is stagnantly red.
