PARIS – : that is, from alopecia areata to vitiligo, and points in between, according to a large German national study.
These dermatologic comorbidities are in addition to already well established strong associations between AD and allergic rhinitis and bronchial asthma, as well as the emerging evidence of increased risk for depression, sleep impairment, suicidality, and other nondermatologic conditions, Nicole Zander noted at the annual congress of the European Academy of Dermatology and Venereology.
“Atopic dermatitis patients seem to be at substantial risk for a variety of comorbidities. It’s important to recognize the whole spectrum of comorbidities as a prerequisite for provision of patient-centered care,” said Ms. Zander, a research associate at the University of Hamburg Institute for Health Services Research in Dermatology and Nursing.
This is a priority in Germany, where the prevalence of AD has doubled or even tripled in the last 3 decades, she added.
She presented a snapshot of the comorbid conditions associated with AD based upon two German large national datasets: Structured skin screening examinations conducted by dermatologists in 162,269 adults working in more than 500 German companies and national medical claims data for 1,349,671 adults aged 18 years and up.
The annual point prevalence for adult AD was 1.4% in the occupational screening, while in the claims dataset it was 3.7%. The true prevalence, as well as that of the dermatologic comorbidities, probably lies somewhere in between, since both of these enormous datasets have their limitations. The claims dataset may contain coding errors, plus many of the skin disorders entombed in that database were diagnosed by nondermatologists. And the occupational dataset is vulnerable to what epidemiologists call the healthy worker effect: some people with severe AD might be absent from work or on disability, with a resultant lower point prevalence of the disorder in the workplace, she explained.
Both datasets documented a clear decline in the prevalence of AD with advancing age. In the medical claims database, for example, the prevalence was 6.6% among 18- and 19-year-olds, 5.4% for patients in their 20s, 3.9% for those in their 30s, 3.4% for those in their 40s, 3.0% for patients in their 50s, 2.7% for those in their 70s, and 2.4% for patients in their 80s.
This is the most likely explanation for the significantly reduced risks of stroke, hypertension, diabetes, hyperlipidemia, and ischemic heart disease seen in AD patients in the claims dataset. These are all conditions that become much more common with advancing age, whereas AD is skewed toward a younger population. And for purposes of this study the data weren’t age adjusted, Ms. Zander observed.
Ms. Zander reported having no financial conflicts regarding her study, conducted without commercial support.
