of patients with AD.

“While we know that head, neck, face, and hands seem to be significantly affected by patients with AD, there is a limited evidence basis regarding the prevalence and health-related quality of life impact of AD in these areas,” presenting author Lawrence F. Eichenfield, MD, said during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis symposium.
For the study, Dr. Eichenfield, professor of dermatology and pediatrics at the University of California, San Diego, and colleagues evaluated 533 patients from the TARGET-DERM AD cohort, an ongoing, longitudinal, observational study launched in 2019 that captures patients with AD in 44 community or academic sites in the United States.
Adult, adolescent, and pediatric patients with moderate or severe Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) scores at enrollment were included in the analysis. The researchers used the Patient-Oriented Scoring AD (PO-SCORAD) index to gather information on involvement of the head, neck, face, hands, or other areas, and the Patient-Oriented Eczema Measure (POEM) and Dermatology Life Quality Index/Children’s DLQI (CDLQI) to measure health-related quality of life outcomes.

Of the 533 study participants, 453 (85%) had AD affecting the head, neck, face, hands, and other areas, while 80 (15%) had AD located in other body regions not including the head, neck, face, or hands. About 38% of all patients were using systemic treatments; most were using topical treatments.
Comorbid immune system disorders (including allergic and hypersensitivity disorders) were noted in 44.8% of patients, infections in 32.5%, asthma in 26.5%, hypertension in 18.6%, depression in 15.8%, and anxiety in 12.4%, with similar proportions observed in those with or without head, neck, face, and hand involvement.
However, patients with head, face, neck, and hand involvement, when compared with patients without those affected areas, were more likely to have severe vIGA scores (28.5% vs. 16.3%, P = .02) and a higher median total body surface area affected (15% vs. 10%, P ≤ .01). Also, while bivariable analyses did not detect statistical differences in POEM and DLQI/CDLQI by body region involvement, multivariable-adjusted models showed that patients with head, neck, face, and hand involvement were more than twice as likely to report higher DLQI/CDLQI (odds ratio, 2.09) and POEM (OR, 2.51) scores than those without head, face, neck, and hand involvement.
“These findings highlight the importance of detailed assessment of specific areas affected by AD to personalize treatment approaches to the needs of patients,” Dr. Eichenfield concluded.
Dr. Raj Chovatiya
Raj Chovatiya MD, PhD, assistant professor of dermatology at Northwestern University, Chicago, who was asked to comment on the study, said that the findings confirm clinical suspicions about the unique and heightened impact of facial, head/neck, and hand dermatitis. “These data show that a detailed skin examination is necessary for a complete assessment of AD,” he said. “Future studies should focus on characterizing the optimal treatment approaches for each of these special sites.”
Dr. Jonathan I. Silverberg
“This is important data,” added primary study author Jonathan I. Silverberg, MD, PhD, MPH, director of clinical research in the division of dermatology at George Washington University, Washington. “We need more high-quality studies like this; we need to create long-term longitudinal data to better understand [the impact of AD on] this and other cohorts.”

Commentary by Robert Sidbury, MD, MPH
Patients with atopic dermatitis (AD) in “visible” areas such as the head, neck, and hands experience a higher impact on their quality of life than those who do not have these areas of involvement. This is a self-evident and unsurprising result but also a particularly important one to document for several reasons. First, evidence-based demonstration of quality-of-life impact is critical as we petition carriers to support the use of newer, more expensive medications. Second, from a topical therapy standpoint, we often use different medications on the head, neck, face, and hands relative to other areas. On the head and neck area we often use either weaker topical steroids to avoid side effects or nonsteroids like topical calcineurin or phosphodiesterase inhibitors; conversely, on the hands we use stronger steroids and are less likely to use nonsteroidal agents that are perceived to be less potent. These data emphasize the need to tailor therapy but ascertain whether standard approaches are satisfactory. If patients are not responding, particularly in these sensitive areas, providers should consider the outsized impact AD may be having on quality of life.
