Atopic Dermatitis (AD) Understanding

Atopic dermatitis (AD) also called eczema, is a chronic condition and the most common type of skin inflammation that usually starts in early childhood, but can occur at any age and can be recurrent or persistent throughout life. In the word ‘dermatitis,’ ‘derm’ means ‘skin’ and ‘itis’ means ‘inflammation.’ Thus, dermatitis is a skin inflammation characterized by itchiness, redness and a rash caused by genetics, an overactive immune system, infections, allergies, and irritating substances.

AD presents different symptoms depending on the age of the person. Itching is the hallmark of AD; more than 85% of people with the condition experience this distressing symptom every day. The exact cause of AD is unknown. The basic understanding of AD is that inflammation results from compromised skin barrier leading to drier skin that is more prone to water loss and the entry of irritants. Thus, AD is caused by a complex interaction of immune dysregulation, epidermal gene mutations, and environmental factors that disrupt the epidermis causing intensely pruritic skin lesions.

There is currently no reliable biomarker that can distinguish the disease from other entities. However, the most commonly used biomarker is elevated total and/or allergen-specific serum IgE. Occasionally, patients carrying an AD diagnosis may display atypical clinical features, chronic dermatoses, infectious processes, and primary immunodeficiency may mimic the presentation leading to the differential diagnosis. Noninfectious dermatoses include contact dermatitis, seborrheic dermatitis, and psoriasis.

At present, there is no specific test for AD, and no single symptom or feature can be used to identify the disease. Each patient has a unique combination of symptoms and rash appearance. Diagnosis of AD is based on the history and physical examination of the patient. In uncertain cases, a skin biopsy may be taken for a histopathological diagnosis of dermatitis.

Atopic Dermatitis (AD) Epidemiology Perspective by DelveInsight

The disease epidemiology covered in the report provides historical as well as forecasted epidemiology segmented by Prevalent Population of Atopic Dermatitis, Diagnosed Prevalent Population of Atopic Dermatitis, Severity-specific Distribution of Atopic Dermatitis in Adults, Severity-specific Distribution of Atopic Dermatitis in Pediatric Population, Gender-specific Distribution of Atopic Dermatitis in Adults, and Chronic Pruritus Prevalence in Atopic Dermatitis in the adults in the United States, EU5 (Germany, Spain, Italy, France, and United Kingdom), and Japan market from 2021 to 2034.

Key Findings

This section provides glimpse of the AD epidemiology in the United States, EU5 (Germany, Spain, Italy, France, and United Kingdom), and Japan.

The total diagnosed prevalent population of AD in the United States, EU5 (Germany, Spain, Italy, France, and United Kingdom), and Japan was estimated to be 25,091,967 in 2020.
Epidemiology assessed for AD showed that the US, in 2020, accounted for approximately 32,197,083 prevalent cases of AD.
In the EU5 countries, the prevalent population of AD was maximum in UK with 7,195,160 cases, followed by the France with 6,585,281 cases in 2020. While, the least number of cases were in Spain, with 4,678,148 cases in 2020.
Japan accounted for 9,510,049 prevalent AD cases in 2020.
The number of chronic pruritus adult prevalent population of AD in the United States is estimated to be 13,643,033 in 2020.
The total diagnosed prevalent population of AD in the seven major markets was found to be 52,941,993 in 2020. In the case of AD patients in the United States, the diagnosed prevalent cases were estimated to be 24,039,022 in 2020.
As per the analysis, a higher percentage of mild AD was observed in the 7MM, followed by moderate AD and severe AD in 2020 in the case of both children and adults. In the US, mild AD accounted for the highest cases in 2020, followed by moderate AD with 9,631,982 and 4,638,631, respectively. In contrast, the lowest cases were found in severe AD, with 1,765,569 cases, in 2020.
Among the gender-specific prevalent contribution, females are affected more by AD than males. In 2020, there were 6,039,851 prevalent cases of AD in males and 10,010,776 prevalent cases in females in the US.

Total prevalent population of Atopic Dermatitis (AD).
Total diagnosed prevalent population of Atopic Dermatitis (AD).
Delvelnsight has analysed gender-specific distribution of AD. As per the analysis, AD is more prevalent in females than in males.
In addition, severity-specific data of AD was analyzed, according to which the adult and pediatric population of AD can be categorized as mild, moderate and severe AD. As per the DelveInsight estimates, it has been found that the mild form of AD included maximum cases, while minimum number of cases were found in severe form of AD in both the populations. This trend is clearly evident in the United States, EU5 (Germany, Spain, Italy, France, and United Kingdom), and Japan for the study period 2021-2034.

Analyst Comments

Various epidemiology studies and international surveys on the prevalence of AD have been conducted in the the 7MM. Data from these studies indicate that AD is a common skin disease in both children and adults, predominantly in the adult female population. Some studies have also indicated a three-fold increase in the past few decades.
