What is atopic dermatitis, and what causes it?
Atopic dermatitis is a chronic skin condition caused by a combination of genetic, immune, and environmental factors. It is linked to an overactive immune response, particularly the activation of Th2 cells, which mistakenly attack the body’s own tissues instead of external threats like bacteria or viruses. Environmental triggers such as pollution, stress, and a Westernized lifestyle can also contribute to the condition1.
Why is atopic dermatitis common in children?
Babies are often exposed to maternal immune cells during pregnancy, which may become overactive and trigger atopic dermatitis shortly after birth. Most cases occur between 6 months and 2 years of age. Symptoms such as rashes and itching often persist into childhood and adolescence2.
Does atopic dermatitis disappear in adulthood?
Not always. Some children outgrow the condition due to changes in their immune system and environmental exposures. However, others may experience flare-ups during puberty or even as adults. Conversely, some adults develop atopic dermatitis later in life for the first time.
How do symptoms differ between children and adults?
- Children: Symptoms are often concentrated on flexural areas like elbows and knees. Frequent scratching can lead to thickened, leathery skin (lichenification).
- Adults: Red patches and irritation tend to occur on the face and neck.
How is atopic dermatitis different from psoriasis or eczema?
- Psoriasis: Characterized by thick, scaly skin with white or silver plaques, often without itching. It’s more seasonal and common in winter.
- Atopic Dermatitis: Causes intense itching and redness, often with fluid discharge.
- Eczema: A broad term that includes various skin inflammations, including atopic dermatitis and psoriasis.
Why does dry weather worsen skin conditions?
Dry, cold air reduces the skin’s natural moisture, weakening its barrier function and making it prone to itching and irritation. This can also exacerbate allergies like allergic rhinitis, which may further trigger skin sensitivity.
What is severe atopic dermatitis, and how is it diagnosed?
Severe atopic dermatitis is assessed using the EASI (Eczema Area and Severity Index).
- For ages 12 and older: EASI ≥23 with no improvement after three months of treatment.
- For ages 6–11: EASI ≥21 with no improvement after four weeks.
- For ages 5 and under: EASI ≥21 with persistent symptoms after four weeks.
Severity influences treatment, which may include topical therapy, immunosuppressants, or biologics3.
What complications or side effects can arise from severe atopic dermatitis?
- Physical: Pain, oozing, crusting, and difficulty sleeping.
- Children: Slower growth and higher risk of infections.
- Medication: Long-term steroid use may cause cataracts, osteoporosis, or diabetes.
Are there social implications of atopic dermatitis?
Severe cases can limit social activities, especially for children. School absenteeism, bullying, and low self-esteem are common issues. In extreme cases, patients may suffer from anxiety, depression, or even suicidal thoughts.
What treatments are available for atopic dermatitis?
New treatments have reduced reliance on steroids, including biologics like dupilumab and oral medications such as upadacitinib. Consult a dermatologist for tailored therapy and to monitor potential side effects of new medications.
What lifestyle habits help manage atopic dermatitis?
- Moisturizing: Apply year-round to strengthen the skin barrier.
- Diet: Avoid processed foods, artificial colors, and preservatives.
- Hydration: Drink at least 2 liters of water daily.
- Exercise: Boosts immunity and overall health.
