Atopic dermatitis epidemiology

Prevalence and incidence of atopic dermatitis

Atopic dermatitis, or atopic eczema, is the most common chronic skin condition and is characterised by acute episodes of eczematous, pruritic lesions over dry skin. It typically starts in early childhood and is widely reported to affect 15–20% of children and 1–3% of adults1.

Since the 1970s, the incidence of atopic dermatitis has increased 2- to 3-fold in industrialised nations2.

While atopic dermatitis affects a substantial number of infants and adults, the severity can differ significantly between patients. Studies have shown reasonable heterogeneity in the relative levels of severity observed in patients. Analysis of the 2007–2008 National Survey of Children’s Health found that 67% of US children reported mild disease, 26% reported moderate disease and 7% reported severe disease3,4. However, a smaller study in the UK where disease severity was assessed by a dermatologist rather than patient self-report found that 84% of children had mild disease, 14% had moderate disease and just 2% had severe disease5.

In children, 60% develop the disease in the first year of life and 90% within the first 5 years of life7. It is also believed to represent the first step of the ‘atopic march’ towards other allergic conditions later in life such as asthma or allergic rhinitis1. In a 3-year, double-blind study of 1,091 infants (3–18 months of age) with recent onset atopic dermatitis (≤3 months), development of one or more atopic comorbidities was observed in 37.0% of infants at the end of observation (mean 2.8 years)8.


Figure 2: Incidence of different atopic diseases in childhood and adolescence (adapted from Barnetson & Rogers9).

In 70% of patients with childhood atopic dermatitis a spontaneous remission before adolescence is achieved1. Interestingly, however, a prospective cohort study of children with mild-to-moderate atopic dermatitis reported that 80% of patients with >5 years of follow-up continued to have symptoms or use medication. Furthermore, as patients aged, they sought healthcare support less frequently potentially influencing the common perception of the frequency with which atopic dermatitis resolves over time10. However, conflicting data and ongoing debate continues on this topic indicating that more research is needed to fully understand the long-term impact of atopic dermatitis11,12,13.

Although prevalence figures of 15–20% in children and 1–3% in adults are commonly quoted1, the American Academy of Dermatology guidelines suggest a childhood prevalence of up to 25%7.

Irrespective of the given prevalence, all these figures hide significant geographic and population variations. In the International Study of Asthma and Allergies in Childhood (ISAAC), a global study of 2 million children in 100 countries, prevalence in children aged 6–7 years was shown to be as low as 0.9% in parts of India and as high as 22.5% in Ecuador14.

Atopic dermatitis pathophysiology

A complex range of factors influence the development and onset of atopic dermatitis, but what is the underlying mechanism that drives skin barrier dysfunction and inflammation? Discover how breakdown of the skin barrier can lead to allergen penetration and immune system activation.

Professor Seemal Desai describes current key hypotheses and research areas regarding the specific mechanisms involved in the pathophysiology of atopic dermatitis.


In the past, atopic dermatitis was thought to be primarily a consequence of immune dysfunction in susceptible children. However, recent advances point towards a complex pathophysiology with genetic, barrier function, immunity and environmental factors acting together and synergistically to drive barrier dysfunction, inflammation and disease progression25.

Two theories have been proposed for the pathophysiology of atopic dermatitis. The inside-out model proposes that an allergic response triggers inflammation that disrupts the skin barrier enabling further allergen and microbe exposure. The outside-in hypothesis, however, suggests that skin barrier dysfunction initiates the process of atopic dermatitis, with immune dysregulation occurring subsequently2.


Figure 6: Theories of atopic dermatitis pathogenesis (adapted from Sidbury & Barton32).

While some suggest that these models are unlikely to be exclusive and probably both play a role2, others suggest that skin barrier dysfunction, or the outside-in model, is the initiating step26.

Skin barrier dysfunction and atopic dermatitis

Within the epidermis, barrier proteins including filaggrin, transglutaminases, keratins and loricrin, and intercellular proteins cross-link into clusters to form an impermeable barrier26. This protects us from exogenous stressors and allergens, but also helps maintain internal fluid and electrolyte homeostasis. Disruption of the skin barrier enables the penetration of allergens that can trigger an immune response and may subsequently lead to the development of IgE-mediated allergies25. While skin barrier dysfunction is critical to the onset of atopic dermatitis, no individual cause has been identified. Instead, several factors contribute to the loss of skin barrier function.


Figure 7: Skin barrier dysfunction and atopic dermatitis (adapted from Peng & Novak33; Guttman-Yassky et al.34). Genetic, immunological, and mechanical factors lead to skin barrier dysfunction allowing activated antigen-presenting cells to encounter allergens, pathogens, and environmental factors. This results in promotion of a Th2-mediated immune response further damaging the skin barrier and inducing keratinocyte apoptosis. Increases in PDE4 also increase Th2 cytokine expression. Virulence factors released by colonising pathogens can also promote keratinocyte cell death and Th2-type inflammation further driving barrier dysfunction.

Epidermal barrier protein loss

While filaggrin plays an important role in the development of barrier protein clusters, it is also degraded upon exposure to low humidity into free amino acids, which are essential for maintaining skin pH and retaining water in the cornified layer35,36,37,38. Mutation of the filaggrin gene, FLG, is a well-known predisposing factor for atopic dermatitis development.

Filaggrin deficiency has been shown to cause paracellular skin barrier abnormalities that reduce inflammatory thresholds to irritants and haptens26. However, a significant number of patients with atopic dermatitis do not have a FLG mutation and approximately 40% of individuals with FLG-null alleles do not go on to develop atopic dermatitis39,26.

While FLG mutations clearly contribute to the development of atopic dermatitis in many people, it is not sufficient alone to generate the condition. Interestingly, FLG mutation is not the only means by which filaggrin levels are reduced.

A Th2-type inflammatory response is typically observed in acute atopic dermatitis and the Th2 cytokines IL-17, IL-22, IL-25 and IL-31 are capable of downregulating filaggrin expression. Indeed, while filaggrin mutations are observed in about one-third of Caucasian patients with atopic dermatitis, skin barrier impairment and reduced filaggrin expression are seen in most patients33.

Tight junctions, desmosomes and adherens junctions form adhesions between the cells of the epidermis to help create a physical, permeability barrier. The Th2 cytokines that downregulate filaggrin expression have also been shown to downregulate the proteins involved in tight junction formation resulting in increased transepidermal water loss, greater allergen and microbial penetration of the skin and reduced skin barrier cohesion40,41,26.

Pruritis in atopic dermatitis

Problematic pruritus in atopic dermatitis

Itch is the most important clinical symptom in atopic dermatitis and has been shown to have a profound impact on the quality of life of both child and adult patients68,69. Importantly, chronic pruritus affects nearly everyone with atopic dermatitis with a point prevalence of 87–100%70,71.

"Without adequate therapy that addresses both the pathophysiological and emotional component of atopic dermatitis-related itch, problems with disease management and adherence to therapy amass in children, putting these patients at increased risk for the long-term sequelae associated with paediatric atopic dermatitis"68.

What are the underlying mechanisms of pruritis in atopic dermatitis?

Watch our expert Professor Martin Steinhoff introduce the signals and mediators involved in pruritis in atopic dermatitis:

Histamine, involved primarily in acute itch, is not alone in mediating pruritis. Having said this, because histamine is a well-known factor causing itch with urticaria caused by the degranulation of mast cells, antihistamine have been commonly used as a treatment. However, it has been found that because many other mechanisms are involved in the pathophysiology of the condition, antihistamines are not fully effective as a management strategy72.

Understanding itch in atopic dermatitis

It is apparent that histaminergic (as seen in urticaria) and non-histaminergic (such as atopic dermatitis) mechanisms can drive pruritus. While closely related, these two mechanisms appear to be independent of one another. In the skin, both mechanisms of pruritus have their own receptors and cutaneous nerve fibres, which continues into the central nervous system (CNS) where each has its own specialised tracts and neural structures73. Chronic pruritus, as seen in atopic dermatitis, is induced by the nonhistaminergic pathway and is likely to be a consequence of multiple factors related to skin barrier dysfunction.

Transepidermal water loss (TEWL) increases following skin barrier dysfunction due to a reduction in keratinocyte retention of water and increased loss of water from the surrounding epidermal environment74. Increased TEWL has been associated with itch intensity and has also been shown to increase the pH of the skin resulting in activation of serine proteases that promote further pruritus75,76. In fact, in atopic dermatitis, the receptor for proteases is typically upregulated and sensitised73.

Skin barrier dysfunction is also likely to allow increased entry of irritants and pruritogens, which further enhance the itch process. Upon entry to the skin, these compounds are capable of stimulating one of myriad receptors on the keratinocyte cell surface channels (such as PAR2, TRPV ion channels, IL-31 receptor, opioid receptors), promoting the release of pruritogenic molecules (including opioids, proteases, substance P, nerve growth factor, neutrotrophin 4, endocannabinoids). In addition, keratinocytes can release acetylcholine directly stimulating sensory nerves as well as lowering their threshold for stimuli activation73. Keratinocytes, therefore, can be stimulated by, and secrete, pruritic factors as well as communicate the itch sensation downstream.

Managing itch is multifactorial with a need to address the itch itself, but also contributing factors such as dry skin, inflammation, and scratch lesions. Basic therapy should be undertaken to address skin barrier dysfunction and includes the use of emollients, bath oils and avoiding any clinically relevant allergens. Beyond basic therapy, a range of topical and systemic treatment options are often used to help manage the itch associated with atopic dermatitis69.

Cytokines in itch

Cytokines are critical components in the pathogenesis of atopic dermatitis with some also playing an important role in atopic itch.


Intradermal injection of IL-2 into patients with atopic dermatitis or healthy controls induced itching and erythema for 48–72 hours77. This link between IL-2 and itch has also been observed in patients receiving intravenous IL-2 as a cancer therapy with severe pruritus a recognised side effect78,79,80. Calcineurin promotes IL-2 synthesis and secretion80 and calcineurin inhibition with ciclosporin A was shown to reduce pruritus in patients with atopic dermatitis81.

IL-4 and IL-13

IL-4 and IL-13 help promote the Th2-driven immune response observed in patients with atopic dermatitis. Levels of both cytokines are increased in lesional skin82 and IL-13 levels are elevated in the serum of patients with atopic dermatitis where they correlate with disease severity83. The role of IL-4 and IL-13 in pruritus has been confirmed using a monoclonal antibody that targets the action of both IL-4 and IL-13 (dupilumab), which reduced pruritus severity by over 50% during clinical trials84.

Atopic dermatitis symptoms

Atopic dermatitis, also called atopic eczema or eczema, is an inflammatory, chronic or chronically relapsing skin disease with pruritus as the predominant dermatological symptom68,105,69.

The condition typically presents in infancy, with 60% of cases occurring within the first year, however, it can develop in older patients with approximately one third of adult cases developing in adulthood68,69. Over time, the clinical presentation of atopic dermatitis changes68.

Burden of disease for atopic dermatitis

As a chronic, relapsing skin condition, atopic dermatitis has a significant impact on patients’ quality of life. However, given the age of most patients, and the fact that it can persist into adulthood, atopic dermatitis also places a heavy burden on patients’ family as well as society2.

The misery of living with atopic dermatitis cannot be overstated for it may have a profoundly negative effect on the HRQoL of children and their family unit in many cases.
Lewis-Jones, 2006.

In fact, skin and subcutaneous diseases were the fourth leading cause of nonfatal burden in 2013 Global Burden of Disease Study, with dermatitis (atopic, seborrheic and contact) having the largest burden of that group107. Furthermore, a study using the Children’s Life Quality Index (CLQI) among children (aged 5–16 years) with various chronic diseases found generalised eczema to be second to only cerebral palsy in impact on quality of life108.

Dr Amy Paller discusses the urgent unmet needs that remain for patients with atopic dermatitis

Symptoms and comorbidities in atopic dermatitis

Pruritus, or itch, is the predominant symptom associated with atopic dermatitis. In a US study of 304 patients with atopic dermatitis, 91% experienced itch daily71. The impact of persistent itch should not be underestimated as it has been shown to affect both physical and emotional/psychological quality of life (QoL) domains. Indeed, reducing itch was identified as the most important treatment goal in 36% of patients with atopic dermatitis109. Furthermore, the physical damage caused by repeated scratching can exacerbate skin barrier breakdown and promote establishment of chronic disease68.

What is the burden of atopic dermatitis for patients?

Watch Professor Steinhoff discuss the considerable burden that pruritis can add for patients living with atopic dermatitis.

More recently, skin pain has also been identified as an important symptom associated with the burden of atopic dermatitis. A prospective, questionnaire-based study of patients with atopic dermatitis aged 13 years and older (N=305) established that 42.7% of patients had experienced skin pain in the past week, with 13.8% reporting it to be severe or very severe. Importantly, patients with severe itch and pain had significantly worse QoL scores than patients with only one or neither symptom110.

Asthma and allergic rhinitis

With atopic dermatitis frequently representing the first step in a series of allergy-related conditions (atopic march), it is well established that patients with atopic dermatitis have an increased risk of developing asthma and allergic rhinitis. In children with severe atopic dermatitis, as many as 50% went on to develop asthma and 75% developed allergic rhinitis111 from 14.2% to 52.7% with an odds ratio of developing asthma of 2.14 compared to children without atopic dermatitis. However, this may be higher than the risk for the general population given many of the included studies were performed in the hospital setting112. Interestingly, an Australian longitudinal study showed that childhood atopic dermatitis increased the risk of persistent allergic asthma in adulthood, but not non-allergic asthma offering potential therapeutic insights for these patients113.

Rheumatoid arthritis and inflammatory bowel disease

Gene mapping studies in atopic dermatitis have identified a number of loci involved in immune function that have also been implicated in other immune-mediated inflammatory diseases114. A large retrospective cohort study identified 49,847 individuals (N = 655,815; prevalence of 7.6%) under the age of 40 years who had prevalent atopic dermatitis between 2005 and 2006. After adjusting for age and sex, patients with atopic dermatitis, compared with those without atopic dermatitis, had significantly increased risks of Crohn’s disease, ulcerative colitis and rheumatoid arthritis115.


Figure 9: Risks of inflammatory bowel disease and rheumatoid arthritis comorbidities in patients with atopic dermatitis (adapted from Schmitt et al.115).

While the cause of these associations remains to be confirmed, it has been established that chronic atopic dermatitis, rheumatoid arthritis and inflammatory bowel disease all involve prominent Th1 and Th17 immune responses. It is tempting to speculate that sustained Th1/Th17 inflammation in patients with chronic atopic dermatitis leads to an increased risk of other chronic inflammatory conditions115.

Burden of childhood atopic dermatitis

Sleep disturbance is a significant problem for infants and has been associated with a range of daytime behavioural deficits116,117,118,119. Over 60% of children with atopic dermatitis experience disturbed sleep patterns with rates of up to 89% in children during exacerbations120,18,121. Furthermore, a U.S. population-based study found that children with atopic dermatitis had sleep disturbance at least 4 nights a week3.

Diagnosing atopic dermatitis

Several classification criteria have been developed, but the Hanifin and Rajka criteria originally developed in 1980 remain the most widely used worldwide69.

Diagnosis of atopic dermatitis relies strongly on clinical presentation and is typically made through an extensive history and physical examination2.

The original criteria developed by Hanifin and Rajka are thorough, requiring 3 of 4 basic features (pruritus, typical morphology and distribution, chronic or chronically relapsing dermatitis, personal or family history of atopy) and at least 3 of 23 minor features to be met155. While comprehensive and validated, the extensive criteria make their application difficult in everyday clinical practice. Various revisions have been developed to aid using them in clinical practice including those developed by the UK Working Party who narrowed the criteria down to needing 1 mandatory and 5 major features to be met. These criteria have no requirement for laboratory testing and have been validated in various populations, however, they cannot be applied to very young children156,157,158,159.

To address this limitation of the UK Working Group version, and to make the criteria more streamlined, the American Academy of Dermatology Consensus Conference proposed a further revision (Table 4)7. This version of the criteria has not been validated, but they were deemed suitable for diagnosing atopic dermatitis in patients of all ages2.

Table 4: American Academy of Dermatology consensus conference revision of the Hanifin & Rajka diagnostic criteria for atopic dermatitis (adapted from Eichenfield et al.7).


Watch Dr Amy Paller discuss how atopic dermatitis can affect patients and the impact this has on their lives


At present, no laboratory biomarkers have been identified to aid with the diagnosis of atopic dermatitis. The elevation of total- or allergen specific IgE in serum or the use of skin tests to detect IgE-mediated sensitisation has been proposed. However, this feature is not present in all patients and has led to the terms ‘intrinsic’ (non-IgE-associated) and ‘extrinsic’ (IgE-associated) being used to describe these different forms of atopic dermatitis. However, controversy persists around the use of these terms and the practical applications of IgE detection in patients with atopic dermatitis69. Despite variation in IgE levels, it has been shown that intrinsic and extrinsic atopic dermatitis patient groups had similar underlying expression levels of Th2-related genes. This suggests that the underlying pathophysiology of their atopic dermatitis may be more similar than expected160.

Beyond diagnostic biomarkers, there is a general lack of biomarkers available to support patient stratification and management. In the past, treatment was typically nonspecific and consisted of topical and systemic immunosuppressants. However, many patients failed to respond to treatment leading to concerns among patients. With the advent of targeted biologic therapies in atopic dermatitis, identification of eligible patients who are likely to respond to therapy is now of increased need to reassure patients and avoid costly treatment failure161.

Numerous studies are currently ongoing looking at a variety of potential atopic dermatitis biomarkers. However, at present none have been shown to be reliable or sensitive enough to support regular clinical use2,69.
