Methods: We conducted a retrospective chart review from January 2022 through January 2024 and identified 79 children aged 0\u20135 years who were prescribed dupilumab in the Massachusetts General Brigham healthcare system. We defined the patient population (including demographics, atopic comorbidities, and neurocognitive burden), and assessed whether time to treatment access varied by patient or prescriber characteristics. Results: The mean age at dupilumab initiation was 3.4 years, and 62.0% of patients were male. The cohort was diverse (48.1% White, 25.3% Black, 16.5% Hispanic\/Latino, 10.1% Asian\/other), with 48.1% publicly insured. Atopic comorbidities were common: 64.6% had food allergies, 34.2% had asthma, and 10.1% had eosinophilic esophagitis (EOE); 73.4% had two or more atopic diagnoses. Neurodevelopmental disorders affected 43.0% of patients, with speech and language delay most frequent (25.3%) and higher rates among those with EOE (87.5% vs. 38.0%, p &lt; 0.01). The mean time to dupilumab approval was 20.9 days, with dermatologists achieving faster approvals than other specialists (10.6 vs. 51.9 days, p &lt; 0.001). Conclusions: Our findings reveal infrequently reported high rates of atopic and neurologic comorbidities in young children with AD and underscore the importance of coordinated inter-specialty collaboration to ensure timely access to dupilumab for these patients.<\/jats:p>","DOI":"10.3390\/children12121639","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T08:49:22Z","timestamp":1764665362000},"page":"1639","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Retrospective Study of Severe Atopic Disease in Young Children (0\u20135 Years) Managed with Dupilumab Highlights Significant Comorbidities"],"prefix":"10.3390","volume":"12","author":[{"given":"Evelyn F.","family":"Fagan","sequence":"first","affiliation":[{"name":"Department of Medical Education, Mercer University School of Medicine, Savannah, GA 31404, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0862-3339","authenticated-orcid":false,"given":"Elena B.","family":"Hawryluk","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Massachusetts General Hospital, Boston, MA 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"LaDonya","family":"Jackson-Cowan","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Massachusetts General Hospital, Boston, MA 02114, USA"},{"name":"Department of Dermatology, University of Miami, Miami, FL 33136, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"417","DOI":"10.1016\/j.anai.2020.12.020","article-title":"Atopic dermatitis in the pediatric population","volume":"126","author":"Silverberg","year":"2021","journal-title":"Ann.
