Eczema (Atopic Dermatitis): Complete Guide to Management and Treatment

Eczema, also known as atopic dermatitis, is one of the most common chronic skin conditions affecting millions worldwide. This inflammatory skin disorder causes significant discomfort and can impact quality of life, but with proper understanding and management, symptoms can be effectively controlled.

Understanding Eczema

What is Eczema?

Eczema is a chronic inflammatory skin condition characterized by:

Red, itchy, and inflamed skin patches
Dry, scaly, or thickened skin areas
Episodes of flare-ups followed by periods of remission
A tendency to develop alongside other allergic conditions (atopic triad: eczema, asthma, and allergic rhinitis)

Types of Eczema

While atopic dermatitis is the most common form, several types exist:

Atopic dermatitis: The classic form, often hereditary
Contact dermatitis: Caused by direct contact with irritants
Dyshidrotic eczema: Affects hands and feet with small blisters
Nummular eczema: Coin-shaped patches on the body
Seborrheic dermatitis: Affects oily areas like the scalp

Causes and Risk Factors

Primary Causes

Eczema results from a combination of factors:

Genetic predisposition: Strong family history of allergic conditions
Immune system dysfunction: Overactive inflammatory response
Skin barrier defects: Impaired skin protection leading to moisture loss
Environmental triggers: Allergens, irritants, and climate factors

Common Triggers

Understanding and avoiding triggers is crucial for management:

Environmental: Pollen, dust mites, pet dander, mold
Chemical irritants: Soaps, detergents, fragrances, cosmetics
Physical factors: Extreme temperatures, humidity changes, sweating
Food allergens: Dairy, eggs, nuts, wheat (in some individuals)
Stress and emotions: Can worsen existing symptoms
Infections: Bacterial or viral infections can trigger flares

Prevalence and Impact

Global Statistics

Affects approximately 15-20% of children and 1-3% of adults worldwide
In Singapore, about 20% of school children have eczema
30-40% of childhood cases may continue into adulthood
Increasing prevalence in developed countries due to “hygiene hypothesis”

Quality of Life Impact

Eczema significantly affects:

Sleep quality due to nighttime itching
School or work performance
Social interactions and self-esteem
Family dynamics and caregiver burden
Economic burden through medical costs and lost productivity

Symptoms and Presentation

Core Symptoms

The hallmark symptoms include:

Intense itching (pruritus): Often the first and most distressing symptom
Dry, scaly skin: Loss of natural moisture barrier
Red, inflamed patches: Areas of active inflammation
Skin thickening (lichenification): From chronic scratching
Oozing and crusting: In severe or infected cases

Infant Eczema (2 months - 2 years)

Location: Face, scalp, cheeks, chin, forehead
Characteristics: Red, oozing, crusty patches
Behavior: Excessive crying, sleep disruption
Special considerations: Avoid over-bathing, gentle products only

Childhood Eczema (2-12 years)

Location: Elbow creases, knee bends, neck, wrists, ankles
Characteristics: Dry, scaly, thickened skin
Complications: Secondary bacterial infections from scratching
School impact: Concentration difficulties, social challenges

Adult Eczema (12+ years)

Location: Hands, neck, face, eyelids, skin fold areas
Characteristics: Very dry, thick, leathery skin
Work-related factors: Occupational triggers, hand eczema
Psychological impact: Increased stress, depression risk

Diagnosis

Clinical Assessment

Diagnosis is primarily clinical, based on:

Medical history: Personal and family history of allergies
Physical examination: Distribution and appearance of lesions
Symptom assessment: Itching patterns, trigger identification
Rule out other conditions: Contact dermatitis, psoriasis, infections

Diagnostic Criteria

Major criteria include:

Pruritus (itching)
Typical morphology and age-specific patterns
Chronic or relapsing course
Personal or family history of atopy

Additional Testing

When necessary:

Patch testing: For suspected contact allergies
Skin prick tests: For environmental and food allergies
Blood tests: IgE levels, specific allergen testing
Skin biopsy: Rarely needed, only if diagnosis uncertain

Treatment and Management

Treatment Philosophy

Effective eczema management requires:

Barrier repair: Restoring skin barrier function
Inflammation control: Managing active flare-ups
Trigger avoidance: Identifying and eliminating triggers
Long-term maintenance: Preventing future flare-ups

Topical Treatments

Moisturizers (First-line therapy)

Application: Multiple times daily, especially after bathing
Types: Creams, ointments, lotions (ointments most effective)
Ingredients to look for: Ceramides, hyaluronic acid, glycerin
Avoid: Fragrances, dyes, preservatives

Topical Corticosteroids

Mild potency: Hydrocortisone for face, neck, skin folds
Moderate potency: Triamcinolone for body areas
Strong potency: For thick, lichenified skin (limited use)
Application: Thin layer, avoid long-term use on sensitive areas

Topical Calcineurin Inhibitors

Examples: Tacrolimus, pimecrolimus
Benefits: No skin thinning, safe for facial use
Usage: Second-line treatment, steroid-sparing agents
Considerations: May cause initial burning sensation

Systemic Treatments

Oral Antihistamines

Purpose: Reduce itching, improve sleep
Types: Sedating (nighttime) vs. non-sedating (daytime)
Examples: Diphenhydramine, loratadine, cetirizine

Oral Corticosteroids

Usage: Severe flares only, short-term
Cautions: Significant side effects with long-term use
Alternatives: Preferred to explore other options first

Immunosuppressants

For severe, treatment-resistant cases:

Cyclosporine: Rapid improvement, requires monitoring
Methotrexate: Weekly dosing, liver function monitoring
Azathioprine: Alternative option, requires genetic testing

Advanced Therapies

Biologics

Dupilumab: First FDA-approved biologic for eczema
Mechanism: Blocks IL-4 and IL-13 pathways
Eligibility: Moderate to severe eczema not controlled with topicals
Administration: Subcutaneous injection every 2 weeks

Phototherapy

Types: Narrowband UV-B, PUVA therapy
Benefits: Reduces inflammation, improves symptoms
Considerations: Risk of skin aging, cancer (long-term)
Monitoring: Regular skin examinations required
