What are the recommended treatment options for a child with pediatric atopic dermatitis?

Management of Pediatric Atopic Dermatitis

All children with atopic dermatitis require regular emollient therapy as the foundation of treatment, with topical corticosteroids added based on disease severity—low-potency for mild disease, medium-potency for moderate disease, and consideration of wet-wrap therapy or topical calcineurin inhibitors for severe refractory cases. 1, 2

Foundational Therapy for All Patients

Every child with atopic dermatitis, regardless of severity, must receive:

• Emollients applied liberally and regularly to all skin, not just affected areas, as this provides both short- and long-term steroid-sparing effects 1, 2
• Lukewarm baths (10-15 minutes) using gentle, soap-free cleansers, followed immediately by emollient application within 3 minutes to lock in moisture 1, 2
• Trigger identification and avoidance including irritants (harsh soaps, wool clothing), allergens, excessive sweating, temperature/humidity changes, and psychological stress 1, 3
• Comprehensive caregiver education about the chronic relapsing nature of the disease and proper application techniques for all topical medications 2, 3

Severity-Based Treatment Algorithm

Mild Atopic Dermatitis

Use reactive therapy only:

• Low-potency topical corticosteroids (hydrocortisone 1%) applied once or twice daily to active lesions until significantly improved, typically 3-7 days 2, 4
• Continue emollients throughout and after flare resolution 2

Moderate Atopic Dermatitis

Combine reactive and proactive therapy:

• Low to medium-potency topical corticosteroids (fluticasone, mometasone) applied once or twice daily during active flares 1, 3
• Proactive maintenance therapy with twice-weekly application of the same corticosteroid to previously affected areas for up to 16 weeks to prevent relapses 1, 3
• This proactive approach significantly reduces flare frequency compared to reactive-only treatment 1

Severe to Very Severe Atopic Dermatitis

Escalate to intensive topical therapy before considering systemic options:

• Medium to high-potency topical corticosteroids for trunk and extremities, with low-potency agents reserved for face, neck, and skin folds to avoid atrophy 1, 3
• Wet-wrap therapy as second-line treatment: apply topical corticosteroid, cover with wet layer of tubular bandages, then dry layer on top for 3-7 days (maximum 14 days in severe cases) 1, 3
• Topical calcineurin inhibitors (tacrolimus 0.03% or 0.1%, pimecrolimus 1%) for children ≥2 years, particularly effective for facial and intertriginous areas where corticosteroid side effects are concerning 1, 5
• Consider systemic therapy (cyclosporine, dupilumab) only after failure of optimized topical therapy 6

Age-Specific Corticosteroid Selection

Infants (<2 years):

• Only low-potency corticosteroids (hydrocortisone 1%) due to high body surface area-to-volume ratio and increased risk of hypothalamic-pituitary-adrenal axis suppression 2, 4
• Monitor closely for skin atrophy, striae, and systemic absorption 4

Children (2-12 years):

• Low to medium-potency corticosteroids as first-line during flares 2, 3
• Topical calcineurin inhibitors approved for this age group as steroid-sparing alternatives 1, 5

Adolescents (>12 years):

• Medium to high-potency corticosteroids acceptable for trunk and extremities 2
• Continue low-potency for sensitive areas 2

Topical Calcineurin Inhibitor Specifics

When to use preferentially:

• Facial, periocular, or genital involvement where corticosteroid atrophy risk is highest 1
• Patients requiring prolonged maintenance therapy to avoid long-term corticosteroid exposure 1
• Children ≥2 years with moderate disease not adequately controlled with low-potency corticosteroids 5

Clinical trial data shows:

• 35% of pediatric patients (ages 2-17) achieved clear or almost clear skin at 6 weeks with pimecrolimus versus 18% with vehicle 5
• Significant improvement in erythema and infiltration visible by day 8, with overall treatment effect by day 15 5
• Common side effect is transient burning/stinging at application site 1, 5

Critical Safety Precautions

Avoid these common pitfalls:

• Never use high or ultra-high-potency corticosteroids in infants due to exponentially increased risk of HPA axis suppression from their high surface area-to-volume ratio 2, 4
• Avoid long-term topical antibiotics as they increase bacterial resistance and cause skin sensitization without proven benefit in non-infected eczema 2, 3
• Limit systemic corticosteroids to 2-week tapering courses for severe acute exacerbations only, as abrupt discontinuation causes severe rebound flares 2, 3, 6
• Do not use phototherapy in children <12 years as long-term safety data regarding skin cancer risk is lacking 3
• Provide specific quantity limits when prescribing potent corticosteroids and reiterate safe application sites to prevent overuse 1

Adjunctive Therapies

Oral antihistamines:

• Use primarily for sedative properties to address sleep disturbance from severe nocturnal pruritus, not for anti-inflammatory effects 2
• Limited evidence for direct anti-pruritic benefit in atopic dermatitis 2

Infection management:

• Bacterial superinfection (usually Staphylococcus aureus): treat with appropriate systemic antibiotics like flucloxacillin 4
• Eczema herpeticum: requires urgent oral acyclovir 4

When to Refer to Dermatology

Refer promptly when:

• Disease worsens despite 4 weeks of appropriate emollient therapy plus low-potency topical corticosteroids 2
• Suspected secondary infection not responding to initial antibiotic therapy 2
• Consideration needed for wet-wrap therapy, which requires specialized instruction 1
• Systemic immunosuppressive therapy may be necessary for severe refractory disease 6
