Early newborn emollient was linked to less eczema at five years in high-risk infants

Design

Single-centre randomised trial, blinded five-year follow-up

Population

177 high-risk term infants assessed at five years, Ireland

Primary outcome

Point prevalence of atopic dermatitis at five years

Effect

12.3% vs 24.0%; RR 0.52 (95% CI 0.26–1.02)

The single-centre Irish STOP-AD trial randomised term infants at high risk of atopic dermatitis, within four days of birth, to twice-daily whole-body emollient for the first eight weeks of life or to routine skin care. This report is the blinded, in-person assessment at five years.

Of 177 children assessed, atopic dermatitis was present in 12.3% of the emollient group and 24.0% of controls (RR 0.52, 95% CI 0.26–1.02; P = .048). Among affected children, disease was milder with emollient (median SCORAD 12.0 vs 19.6). Multiple imputation for missing children gave a similar estimate with an interval crossing no effect (OR 0.45, 0.19–1.03).

Larger trials of emollients for eczema prevention have given mixed results, and this is a small single-centre study with attrition. But eight weeks of emollient is cheap and low-risk. For families with a strong atopic history who ask what they can do, it is reasonable to discuss it as an option with uncertain benefit.

• Consider discussing short-term daily emollient from birth with families at high atopic risk
• Explain that the evidence is mixed and the benefit uncertain
• Choose a bland, fragrance-free emollient and avoid food-based oils
• Stop and review if the skin becomes irritated or infected
• Continue to treat established eczema early and adequately; prevention does not replace treatment

Why it matters

A cheap eight-week intervention with a possible five-year effect would change newborn skin advice if confirmed.

Don't overread it

The confidence interval includes no effect, and larger emollient prevention trials have not consistently shown benefit.

The statistics, in plain English

A risk ratio of 0.52 suggests about half the eczema, but the confidence interval runs up to 1.02, meaning no effect is still possible. When missing children were accounted for, the result was no longer statistically significant. With 177 children, the trial is too small to give a precise answer.
