Abstract

Atopic dermatitis (AD) is a chronic skin condition that can manifest in childhood and persist into adulthood or can present de novo in adults. The clinical presentation of adults with AD may differ among those with pediatric-onset versus adult-onset disease and potential differences between both groups remain to be better characterized. These atypical features might not be encompassed as part of current diagnostic criteria for AD, such as the Hanifin-Rajka (H-R) and the U.K. Working Party (UKWP) criteria. We conducted a retrospective chart review of the electronic medical records of a large, single, academic center to compare the clinical characteristics between adult-onset and pediatric onset AD and examine the proportion of patients who meet the H-R and/or UKWP criteria. Our single-center retrospective chart review included adults (≥ 18 years of age) with any AD-related ICD-10 codes, ≥ 2 AD-related visits, and a recorded physician-confirmed AD diagnosis. Descriptive statistics were used to compare adults with pediatric-onset (< 18 years of age) and adult-onset (≥ 18 years of age) AD. Logistic regression and x2 test were used to compare groups. We found that, compared to pediatric-onset AD, adults with adult-onset AD had less flexural involvement, flexural lichenification and a personal and family history of other atopic diseases. Compared to adults with pediatric-onset AD, adults with adult-onset AD had greater involvement of the extensor surfaces and more nummular eczema compared to pediatric-onset AD. In our cohort, adults with adult-onset AD were less likely to meet H-R and UKWP criteria compared to pediatric-onset AD. Adults with adult-onset AD may present with a clinical presentation that is different from those with pediatric-onset AD, which may not be completely captured by current AD criteria such as the H-R and UWKP criteria. This can lead to possibly mis- or underdiagnosing AD in adults. Thus, understanding the differences and working towards modifying criteria for adult-onset AD has the potential to improve accurate diagnosis of adults with AD.
