Adults and children with atopic dermatitis (AD) had increased cutaneous and extra-cutaneous autoimmune disorders, which were associated with a considerable cost-burden, according to a recent study. Researchers conducted a cross-sectional study of the 2002–2012 National Inpatient Sample, including a ∼20% sample of all US hospitalizations (n=87,053, 155 adults and children). They found:
- The prevalence of autoimmune disease was higher in adults (7.9% [7.3-8.5%] vs 5.7 [5.7-5.8%]) and children (2.0% [1.7-2.3%] vs 1.0% [0.9-1.1%]) with vs without AD.
- In multivariable logistic regression models controlling for socio-demographics, adult and pediatric AD were associated with any autoimmune disorder.
- In particular, AD was associated with 18 of 32 autoimmune disorders examined in adults and 12 of 24 examined in children, including disorders of the skin, endocrine, gastrointestinal, hematologic, and musculoskeletal systems.
- AD patients hospitalized with any autoimmune disorder had higher cost of inpatient care with $2.5-$50 million excess annual costs.
