1-Minute Summary: Functional interaction between sensory neurons and mast cells in the early stage of house dust mite-induced type 2 inflammation and itch: a novel therapeutic target of allergic disease

Expert Name
Miranda Sin-Man Tsang and Chun Kwok Wong

The interaction between the nervous system and immune cells has been reported in fungal-infected skin inflammation and psoriasis, but not in atopic dermatitis (AD) [1-3]. Antihistamines are not always effective in treating pruritus in chronic skin inflammation [4]. A recent study by Serhan et al. unraveled how house dust mite allergens can trigger peripheral nociceptive sensory neurons and how these…

Good response and pruritus reduction in AD with novel selective JAK1 inhibitor

Expert Name
Dr Melinda Gooderham

The JADE Mono-2 study in adolescent and adult patients with atopic dermatitis (AD) investigated the efficacy and safety of abrocitinib. The results demonstrated significant advantages in clinical signs and symptoms over placebo [1,2]. The randomised, controlled, double-blind, phase 3 trial included 391 patients aged ≥12 years with moderate-to-severe AD from 115 centres worldwide and was presented by Dr Melinda Gooderham…

Baricitinib beneficial in head and neck AD

New data from a pooled analysis of phase 3 trials demonstrated substantial efficacy of JAK-inhibition with baricitinib for head and neck lesions in atopic dermatitis (AD) [1]. The oral JAK1/JAK2 inhibitor baricitinib has already proven its efficacy versus placebo in treating moderate-to-severe AD in the identical, double-blind, randomised, controlled, phase 3 BREEZE-AD1 and BREEZE-AD2 trials. Patients with AD often experience…

IL-4/IL-13 blocker dupilumab effective in children with severe AD

Expert Name
Prof. Amy S. Paller

The IL-4/IL-13 blocker dupilumab leads to rapid symptom control and itch reduction in children with severe atopic dermatitis (AD), as was demonstrated in the phase 3 LIBERTY AD PEDS study [1]. Previous trials have already shown that dupilumab is effective in adults and adolescents ≥12 years with moderate-to-severe AD inadequately controlled with topical prescription therapies. However, there is also an…

IL-13 blocker tralokinumab effective in AD

Expert Name
Prof. Eric Simpson

IL-13 plays a key role in pathogenesis of atopic dermatitis (AD). The phase 3 ECZTRA trials demonstrated the remarkable efficacy of the IL-13 blocker tralokinumab in adult patients with moderate-to-severe AD [1]. AD is a chronic inflammatory skin disease. Tralokinumab is a fully human monoclonal antibody designed specifically to neutralise IL-13, a key driver of the underlying inflammation in AD,…
