Effect of bathing on atopic dermatitis during the summer season

ABSTRACT

BACKGROUND: There are little objective data regarding the optimal practice methods of bathing, although bathing and the use of moisturizers are the most important facets to atopic dermatitis (AD) management. OBJECTIVE: We performed this study to evaluate the effect of bathing on AD. METHODS: Ninety-six children with AD were enrolled during the summer season. Parents were educated to bathe them once daily with mildly acidic cleansers, and to apply emollients for 14 days. Parents recorded the frequency of bathing and skin symptoms in a diary. Scoring AD (SCORAD) scores were measured at the initial and follow-up visits. Patients were divided into two groups, based on the compliance of bathing; poor compliance was defined as ≥ 2 bathless days. RESULTS: There was an improvement of SCORAD score, itching, and insomnia in the good compliance group (all p < 0.001). The mean change in SCORAD score from the baseline at the follow-up visit was greater in the good compliance group than the poor compliance group (p = 0.038). CONCLUSION: Daily bathing using weakly acidic syndets can reduce skin symptoms of pediatric AD during the summer season.
