What is Eczema Disease?

A complete Guide to Eczema Disease

Eczema is a group of inflammatory skin conditions, of which atopic dermatitis is the most common type.  Although people of all ages may be affected by it, children are at the greatest risk, and it can have a major effect on quality of life.

Hence, learning about the different causes, symptoms and ways to control the disease is essential for successful management.

What are the Types of Atopic Dermatitis?

Atopic dermatitis, the most common form of eczema, can present in various forms. Here are some types and variations:

What are the Causes of Eczema?

The exact cause of eczema is multifactorial, involving a combination of genetic and environmental factors:

• Genetic Predisposition: Loss-of-function mutations in the filaggrin (FLG) gene are associated with impaired skin barrier function and increased risk of atopic dermatitis.
• Immune System Dysfunction: Immune system hyperreactivity leads to inflammation in response to certain stimuli.
• Environmental Triggers: Exposure to things that cause allergies (such as pollen or dust), irritants (such as soaps or detergents), or low humidity can worsen the symptoms.
• Stress: Emotional stress can worsen or trigger flare-ups.
• Skin Barrier Defects: If skin proteins are altered by mutations, the skin’s ability to protect against drying is reduced and becomes susceptible to irritating factors.

What are the Symptoms of Eczema?

Eczema symptoms can vary but commonly include:

• Dry, Sensitive Skin: The skin might feel rough and look flaky.
• Itching: Often causes severe itching, which further damages the skin.
• Red or Inflamed Patches: Most noticeably on the face, neck and limbs.
• Thickened, Cracked, or Scaly Skin: Due to continuous scratching.
• Oozing or Crusting: In the event of infection.
• Hyperpigmentation or Hypopigmentation: The skin may turn discoloured after inflammation.

What is the Diagnosis of Eczema?

Diagnosis is primarily clinical, based on:

• History of Symptoms: Onset, duration, and pattern.
• Family Medical History: In the context of atopic conditions.
• Physical Examination: Evaluating the pattern and appearance of the skin lesion.
• Allergy Testing: To identify specific triggers.
• Skin Biopsy: To eliminate secondary causes.

What are the Treatment Options for Eczema?

While there is currently no cure, eczema treatment aims to manage symptoms and prevent flare-ups:

 1. Topical Therapies:

• Emollients: Use a moisturizer daily to keep the skin well hydrated.
• Corticosteroids: To lower inflammation during a flare-up.
• Calcineurin Inhibitors: For sensitive areas or intended for long-term use.
  
   

 2. Systemic Treatments:

• Antihistamines: Sedating antihistamines may help improve sleep disturbed by itching, but they do not treat eczema inflammation. Non-sedating antihistamines have limited benefit unless coexisting urticaria or allergic rhinitis is present.
• Immunosuppressants: If topical treatments do not respond in extreme cases.
• Biologic Therapies: Such as dupilumab, are designed to treat moderate-to-severe eczema.

3. Phototherapy:

• Supervised exposure to ultraviolet light.

Consulting with a healthcare provider helps you choose the most effective plan for treatment.

What are the Complications of Eczema?

Eczema can lead to further issues if not effectively controlled. They are as follows:

• Skin Infections: Open wounds created by scratching can be invaded by bacteria (for example, Staphylococcus aureus), viruses (for example, herpes simplex, resulting in eczema herpeticum) or fungi, sometimes resulting in cellulitis or sepsis.
• Chronic Skin Changes: Chronic scratching can lead to the development of thick, leathery patches that won’t disappear.
• Sleep Disturbances: Constant itching late at night may prevent people from sleeping well, leaving them feeling much worse during the day.
• Mental Health Issues: The chronic nature of eczema and its obvious signs can lead to stress and conditions such as anxiety and depression.
• Eye Complications: Severe eczema around the eye can result in conjunctivitis, keratitis or cataracts.

How to Care and Manage Individuals With Eczema?

Effective eczema management involves:

• Identifying and Avoiding Triggers: Such as allergens, irritants, and stressors.
• Maintaining Skin Hydration: Through regular use of emollients.
• Implementing a Skincare Routine: Using gentle, fragrance-free products.
• Wearing Soft, Breathable Fabrics: To minimize skin irritation.
• Regular Monitoring: Follow-ups with healthcare providers are needed to adjust treatment as needed.
• Stress Management: Incorporating relaxation techniques into daily routines.
• Dietary Considerations: Identifying and avoiding food triggers, if applicable.

Does Health Insurance Cover Eczema Treatment?

Many health insurance policies in India cover dermatological conditions, including eczema, especially when treatment is deemed medically necessary.
