What Causes Atopic Eczema?

Atopic eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, itchy, and inflamed skin. Its exact cause is complex and involves a combination of genetic, environmental, and immune system factors.

Genetic Factors

Research shows that atopic eczema often runs in families. If one or both parents have eczema, asthma, or hay fever, their children are more likely to develop the condition. This genetic link suggests that certain inherited traits affect the skin’s barrier function, making it less effective at retaining moisture and protecting against irritants.

For example, mutations in the filaggrin gene are common in people with eczema. Filaggrin is a protein that helps maintain the skin’s protective barrier. When this barrier is weak, e.g. when there is deficiency of filaggrin, the skin becomes more vulnerable to dryness and allergens.

Environmental Triggers

Environmental factors can worsen eczema symptoms or trigger flare-ups. Common triggers include:

• Irritants: Soaps, detergents, fragrances, and harsh fabrics like wool can irritate sensitive skin.

• Allergens: Dust mites, pet dander, pollen, and mold may provoke allergic reactions that worsen eczema.

• Climate: Extreme temperatures, low humidity, or sudden changes in weather can dry out the skin.

• Stress: Emotional stress can increase inflammation and itching.

• Infections: Bacterial or viral skin infections can aggravate eczema symptoms.

  
  

Identifying and avoiding personal triggers is a key part of managing eczema.

Immune System Responses

Atopic eczema involves an overactive immune response. The immune system mistakenly reacts to harmless substances, causing inflammation and skin damage. This immune dysfunction leads to the redness, swelling, and itching typical of eczema.

In some cases, eczema is linked to other allergic conditions like asthma or hay fever, which share similar immune system abnormalities.

Treatment Options for Atopic Eczema

While there is no cure for atopic eczema, many treatments help control symptoms and reduce flare-ups. Treatment plans often combine medications, lifestyle changes, and alternative therapies.

Topical Medications

Topical treatments are the first line of defense against eczema symptoms. These include:

• Moisturisers (Emollients): Regular use of thick creams or ointments helps restore the skin barrier and lock in moisture. Applying moisturisers immediately after bathing is especially effective. Lighter agents may also be used depending on preference and other factors.

• Topical corticosteroids: These anti-inflammatory creams reduce redness and itching during flare-ups. They come in different strengths and should be used under medical supervision to avoid side effects. Concern has been raised about the risk of longterm use and developing topical steroid withdrawl.

• Calcineurin inhibitors: Non-steroid creams like tacrolimus and pimecrolimus reduce inflammation and are useful for sensitive areas like the face.

• Antihistamines: Oral antihistamines may help reduce itching, especially at night.

  
  

Lifestyle Changes

Simple adjustments in daily habits can make a big difference:

• Bathing habits: Use lukewarm water and mild, fragrance-free cleansers. Limit baths or showers to 10-15 minutes.

• Clothing: Wear soft, breathable fabrics such as cotton. Avoid wool and synthetic fibers that irritate skin.

• Environment: Use a humidifier in dry climates and keep living spaces clean to reduce dust mites and allergens.

• Stress management: Techniques like meditation, yoga, or counseling can help control stress-related flare-ups.

• Diet: Keeping a food diary can help identify triggers.

  
  

Alternative Therapies

Some people explore complementary treatments to ease eczema symptoms:

• Wet wrap therapy: Applying wet bandages over moisturised skin can improve hydration and reduce itching.

• Phototherapy: Controlled exposure to ultraviolet light under medical supervision can reduce inflammation.

• Natural remedies: Oatmeal baths, coconut oil, and aloe vera may soothe irritated skin in some individuals.

• Probiotics: Some studies suggest probiotics might help balance the immune system, though evidence is still emerging.

  
  

Always consult a healthcare provider before starting alternative treatments.

Tips for Managing Symptoms and Preventing Flare-Ups

Managing atopic eczema requires ongoing care and attention. Here are practical tips to help keep symptoms under control:

• Moisturise frequently: Apply emollients at least 2-4 times daily, especially after washing.

• Avoid scratching: Keep nails short and consider wearing cotton gloves at night to reduce skin damage.

• Identify triggers: Track flare-ups and note possible causes such as foods, fabrics, or environmental changes.

• Use gentle skin care products: Choose fragrance-free, hypoallergenic soaps and detergents.

• Dress appropriately: Opt for loose-fitting clothes made from natural fibers.

• Maintain a consistent routine: Regular skin care and avoiding sudden changes in environment help stabilize symptoms.

• Stay hydrated: Drink plenty of water to support skin health.

• Seek medical advice: If symptoms worsen or do not improve with home care, consult a dermatologist for tailored treatment.

  
  

Supporting Yourself or Loved Ones with Atopic Eczema

Living with eczema can be frustrating and impact daily life. Understanding the condition and having a clear plan can reduce stress and improve comfort. Support groups and counseling may also help cope with emotional challenges.

Remember, eczema varies from person to person. What works for one individual may not work for another. Patience and persistence are key to finding the right balance of treatments and lifestyle changes for each individual.
