What is the recommended treatment for moderate to severe eczema in a 1-year-old boy?

Treatment for Moderate to Severe Eczema in a 1-Year-Old Boy

For moderate to severe eczema in a 1-year-old boy, the recommended first-line treatment is mild to moderate potency topical corticosteroids combined with regular emollient use, avoiding high-potency corticosteroids due to the risk of systemic absorption in infants. 1, 2

First-Line Treatment

Topical Corticosteroids

• Use mild to moderate potency topical corticosteroids (such as hydrocortisone 1%) for active inflammation 1, 2
• Apply a thin film once or twice daily to affected areas for the shortest period necessary (typically 3-7 days) 3, 1
• Avoid high-potency or ultra-high-potency topical corticosteroids in infants due to their high body surface area-to-volume ratio and increased risk of hypothalamic-pituitary-adrenal (HPA) axis suppression 1, 2
• For sensitive areas (face, neck, diaper area), use only low-potency corticosteroids 1

Emollients

• Apply fragrance-free emollients regularly throughout the day to maintain skin barrier integrity 2
• Emollients have a steroid-sparing effect and should be used even when the skin appears normal 1, 2
• Apply emollients after bathing to lock in moisture 2
• The order of application between emollients and corticosteroids does not significantly affect treatment outcomes (can be applied in either order with a 15-minute interval) 4

Second-Line Treatment Options

Topical Calcineurin Inhibitors

• For facial and genital regions, tacrolimus 0.03% ointment can be considered as an alternative to topical corticosteroids 1
• Particularly useful for sensitive areas where prolonged corticosteroid use may cause atrophy 1

Wet Wrap Therapy

• For severe flares not responding to standard treatment, wet wrap therapy can be effective as short-term crisis intervention 1, 5
• Typically used for 3-5 days under medical supervision 5
• Involves applying corticosteroid, covering with damp bandages, then a dry layer 1

Management of Complications

Secondary Infections

• If signs of bacterial infection are present (crusting, weeping, increased redness), treat with appropriate antibiotics 3
• Flucloxacillin is usually the most appropriate antibiotic for Staphylococcus aureus (most common pathogen) 3
• Erythromycin may be used for penicillin-allergic patients 3
• For eczema herpeticum (herpes simplex infection), prompt treatment with oral acyclovir is necessary 3

Severe Itching

• Sedating antihistamines may be used as a short-term adjunct during severe itching episodes, particularly at night 3, 1
• Non-sedating antihistamines have little value in atopic eczema 3

Maintenance Therapy

Proactive Treatment

• After clearing the acute flare, consider proactive weekend therapy (applying topical corticosteroids twice weekly to previously affected areas) to prevent relapses 2, 6
• This approach significantly reduces the likelihood of relapse compared to reactive treatment 6

Regular Monitoring

• Monitor for signs of skin atrophy, striae, or systemic absorption 1, 2
• Provide careful instruction to caregivers on the amount to apply and safe sites for use 1
• Schedule regular follow-up visits to assess treatment response and adjust therapy as needed 1

Important Considerations and Precautions

• The risk of adverse effects increases with higher potency, occlusion, and prolonged use 1, 6
• Abnormal skin thinning is rare with appropriate use of mild to moderate potency corticosteroids 6
• Studies show that properly used moderate-potency corticosteroids like hydrocortisone butyrate 0.1% can be safe in children without causing adrenal suppression 7
• Avoid long-term application of topical antibiotics due to increased risk of resistance and skin sensitization 2
• Systemic corticosteroids should be avoided due to risk of rebound flares upon discontinuation 2
