Atopic Dermatitis Insights and Trends
- Atopic dermatitis, also called eczema, is a multifaceted, chronic, relapsing inflammatory skin disease commonly associated with other atopic manifestations such as food allergy, allergic rhinitis, and asthma. It is 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.
- According to epidemiological analyses, atopic dermatitis represents a substantial and growing disease burden across the APAC region, with prevalence increasing over recent decades, particularly in urbanized and industrialized countries. Large patient populations in countries such as China, Japan, India, South Korea, and Australia contribute significantly to the regional burden.
- Atopic dermatitis is a common chronic inflammatory skin disorder that frequently begins during infancy and childhood, although disease onset can occur at any age. Across APAC populations, epidemiological studies consistently demonstrate a higher prevalence among pediatric populations compared with adults, highlighting a considerable childhood disease burden.
- Epidemiological findings across multiple APAC countries suggest that atopic dermatitis tends to be more prevalent among females than males, particularly in adolescent and adult populations, although sex distribution may vary across countries and age groups.
DelveInsight's 'Atopic Dermatitis - Epidemiology Forecast - 2036' report delivers an in-depth understanding of Atopic Dermatitis, historical and forecasted epidemiology in the APAC region (India, China, Japan, South Korea, Taiwan, and Australia).
Atopic Dermatitis Understanding and Diagnosis Algorithm
Atopic Dermatitis Overview
Atopic dermatitis, 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 '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. Half of the patients with moderate-to-severe eczema also have asthma, hay fever (allergic rhinitis), and food allergies; it is the most common chronic skin disease in children.
Atopic Dermatitis Diagnosis
Atopic dermatitis is primarily diagnosed clinically, as no definitive laboratory test is available for confirmation. Diagnosis is based on characteristic clinical features, particularly pruritus, which is considered an essential symptom, along with chronic or relapsing eczematous lesions, typical age-specific distribution patterns (such as facial and extensor involvement in infants and flexural involvement in older children and adults), and a personal or family history of atopy. The diagnostic process also involves excluding other dermatologic or systemic conditions that may present with similar symptoms. Patients commonly present with dry skin, excoriations, papules, and lichenification. The absence of itching should prompt reconsideration of the diagnosis.
Differential diagnosis is important, especially for other scaly inflammatory skin disorders, such as seborrheic dermatitis in infants. In cases where patients fail to respond adequately to treatment, alternative diagnoses, including nutritional, metabolic, or immunologic disorders, should be considered. Although elevated serum IgE levels are frequently observed in patients with atopic dermatitis, they are not diagnostic. Additional investigations, including skin biopsy and microbiological testing, may assist in excluding other dermatologic conditions or identifying secondary infections; however, these tests are not definitive for diagnosing atopic dermatitis.
Atopic Dermatitis Epidemiology
Key Findings from Atopic Dermatitis Epidemiological Analysis and Forecast
- A systematic review of East Asian populations reported a rising prevalence of both pediatric and adult atopic dermatitis across Asian countries, particularly in urban populations, indicating a growing disease burden associated with industrialization and lifestyle changes.
- Findings from the International Study of Asthma and Allergies in Childhood (ISAAC) demonstrated marked geographic heterogeneity across APAC, with childhood atopic dermatitis prevalence reported at approximately 1.2% in China, 3.4% in Korea, and 10.5% in Japan, suggesting substantial regional variation.
- Epidemiological studies in Asia indicate that atopic dermatitis prevalence in children ranges widely (<5% to >20%), with prevalence among 6-7-year-old children approaching 10% in several Asia-Pacific populations, emphasizing a considerable pediatric burden.
- Emerging evidence suggests adult-onset atopic dermatitis is increasingly recognized across Asian populations, expanding the patient pool beyond historically pediatric populations and contributing to long-term disease burden.
- A systematic review and meta-analysis evaluating 162 epidemiological studies across Asia identified both genetic and environmental drivers of atopic dermatitis. Family history of atopic disease emerged as a major non-modifiable factor, while maternal smoking and active smoking were among the strongest modifiable risk factors identified.
- Studies evaluating developing Asian countries reported that atopic dermatitis prevalence is increasing rapidly in regions undergoing economic development and industrial transition, further supporting epidemiological shifts across APAC.
- Studies have suggested that children of Asian immigrant populations may demonstrate increased atopic dermatitis risk, highlighting potential interactions between genetic susceptibility and environmental exposures in disease development.
