Eczema Prevalence
- Approximately 31.6 million people in the United States have some form of eczema 19
Atopic Dermatitis Prevalence
- 15-20% of children globally have atopic dermatitis (AD)Â 5
- 15.1% of children in the United States have ADÂ 15
- 1-3% of adults globally have ADÂ 5
- 7.3% of adults in the United States have ADÂ 16
Definition of Atopic Dermatitis
Atopic dermatitis, a form of eczema, is a chronic, non-contagious, inflammatory skin condition that causes dry and itchy skin which sometimes weeps clear fluid 1
Causes of Atopic Dermatitis
The exact cause of AD is unknown, but most cases are a combination of genetics and triggers 2
There are several genetic factors which may lead to AD:
- Individuals who have a parent with a history of AD, asthma, or hay fever are more likely to develop ADÂ 3
- Some people have a mutation in the CARD11 gene, which affects immune system cells 3
- Some people with AD have a mutation in the gene responsible for creating filaggrin, which is a protein that helps create a healthy outer layer of skin 3
There are multiple things that may trigger AD symptoms including:
- Cosmetic Products 4,5
- Clothing 4,5
- Dust Mites 4
- Detergents or Soap 4
- Weather 4,5
- Viral Infections 4,5
- Food allergens 5
- Fragrances 5
Symptoms of Atopic Dermatitis
AD affects the skin and common symptoms include:
- Skin itching 6
- Dry skin 6
- Redness 6
- Puffy or swollen skin 6
- Oozing or crusting from skin 6
- Raw Skin 6
- Thick, leathery patches of skin 6
Treatment of Atopic Dermatitis
Treatment of AD may involve a combination of nonpharmacologic and pharmacologic interventions 7
Nonpharmacologic:
- Skin moisturizers – should be applied after bathing 7
- Bathing 7
- Limit use of non-soap cleansers (should be low-pH, hypoallergenic, fragrance free)Â 7
- Wet-wrap therapy 7
Pharmacologic (under direction of a medical provider):
- Topical corticosteroids (if failure to respond to non-pharmacologic management)Â 7
- Topical calcineurin inhibitors 7
- Not routinely recommended for management – topical antimicrobial agents or antihistamines 7
- Systemic immunomodulating medications 8
- Biologics (Dupilumab, Tralokinumab-ldrm, Abrocitinib, Upadacitinib, Ruxolitinib ) 19, 20, 21, 22
- Providers may also prescribe phototherapy 8
Atopic Dermatitis Disparities
- AD is more common in black children than other racial or ethnic groups 17
- AD is more common in children from families with higher incomes and education 17
- Blacks and Asians/Pacific Islanders are more likely to seek medical care for ADÂ 18
Atopic Dermatitis Burden
- 91% of patients experience itching on a daily basis 12
- Adults with AD report higher rates of anxiety (29.8%), depression (31.2%) and sleep disturbances (33.2%) than the general population 24
- Adults with AD report that it limits their lifestyle (51.3%), lead to avoiding social interaction (39.1%), and impacted activities (43.3%) 26
- Children and adolescents with AD have higher rates of ADHD (12.6%), conduct disorders (7.74%), anxiety (7.25%), depression (6.52%), and autism (3.97%) than the general population 27
- 15.5% of adolescents with AD report suicidal ideation compared to 9.1% of adolescence without 13
- This increases to 23.8% in adolescence with AD and itching 13
- 47-66% of children with AD experience sleep disturbances 14, 25
Economic Burden of Atopic Dermatitis
The total annual cost of AD increased to estimated $5.3 billion in 2015Â 10
The direct costs associated with AD were over $1 billion annually in 2004Â 9
- Average out of pocket expenses are $600 per year, with 42% reporting expenses of over $1000 and 85% reporting expenses over $5000 28
- $636 million for office visits 9
- $154 million for prescription medications 9
- $108 million for outpatient hospital visits 9
- $105 million for emergency department visits 9
- $6 million for inpatient hospital stays 9
The indirect costs associated with AD were $619 million in 2004Â 9
