Dupilumab-associated head and neck dermatitis (HND) is a rare and often underrecognized condition, especially in patients with skin of color. It can vary from subtle to severe presentations, with violaceous hues and seborrheic distribution after dupilumab initiation. Early recognition and management are crucial to prevent treatment discontinuation.

Article Synopsis
  • Atopic dermatitis (AD) is a common chronic skin condition in children, and dupilumab is the first approved biologic treatment for moderate-to-severe cases; however, it can lead to ocular surface disease (DAOSD).
  • A study was conducted on Asian pediatric patients who developed DAOSD while being treated with dupilumab, analyzing their demographic information, eye symptoms, and treatment outcomes.
  • Among 216 patients, 16 (7.4%) experienced DAOSD, mainly presenting with symptoms like eye redness and conjunctivitis; however, the severity in children seemed lower than in adults, and prophylactic measures can help minimize complications.

Background: Real-world data regarding the use of dupilumab in children with atopic dermatitis (AD) are limited.

Objectives: To evaluate the real-world efficacy of dupilumab in children with moderate-to-severe AD over an extended follow-up period.

Methods: This was a retrospective study of patients (≤ 18 years) with moderate-to-severe AD treated with dupilumab in four Israeli tertiary centres.

Article Synopsis
  • Head and neck dermatitis (HND) is a severe form of atopic dermatitis that primarily affects seborrheic areas and significantly impacts patients’ quality of life, with treatment being complicated by the ineffectiveness of usual topical therapies and the potential for dupilumab-associated dermatitis (DAHND).
  • Research indicates that fungi, particularly Malassezia species, play a crucial role in HND development, as they activate the immune system and cause inflammation via specific immune pathways.
  • While antifungals show promise in treating HND, particularly in oral form, the long-term effects are uncertain; new therapies like Janus kinase inhibitors and OX40 inhibitors are being explored, and factors like host microbiome variations could lead to more

Atopic dermatitis (AD) is a prevalent chronic inflammatory skin condition with a substantial impact on patients, particularly due to ocular involvement known as atopic keratoconjunctivitis (AKC). Current therapeutic approaches, such as dupilumab, often lead to conjunctivitis, prompting exploration of alternative treatments like upadacitinib. We collected dermatological and ophthalmological prospective clinical evaluations of six adults with moderate-to-severe AD, undergoing treatment with upadacitinib after discontinuation of dupilumab due to the onset of AKC during therapy and the worsening of dermatitis in particular in the head and neck region.
