gentle cleanser was used for all bathing, and bathing time was limited to less than 8 minutes and rinsing with lukewarm water. No other skin care products were permitted.
For the maintenance phase, the moisturizer group used Body Cream on the entire body at least once per day in addition to the cleanser, while the control group continued with cleanser only (no moisturizer) for 6 months, or until a flare occurred.
Subjects who developed a flare entered the treatment phase. Flare Treatment was applied to the affected area each morning and evening, or more often as necessary, for 4 weeks. After 4 weeks of Flare Treatment, subjects ceased participation in the study.

Assessments

Moisturizer and control groups were compared for the number of subjects who flared in each group and for the time to flare in each group (including mean, median, minimum, and maximum days to flare). Flares were assessed at all treatment phase visits by clinical grading of eczema symptoms of lesions, including erythema, pruritus, exudation, excoriation, and lichenification (0=none, 1=mild, 2=moderate, 3=severe), and by the Atopic Dermatitis Severity Index (ADSI, 0-15 scale), the sum of the component eczema symptom scores. At weeks 2 and 4 of treatment, the degree of improvement was graded by the investigator according the following scale: 1=markedly worse, 2=moderately worse, 3=no change, 4=moderate improvement, 5=marked improvement, 6=clear/almost clear.
Global tolerability was graded by the investigator from 1=excellent to 4=poor at visit 2 (end of washout phase) and visit 3 (week 4 of maintenance phase). For subjects who flared, global tolerability of flare treatment was assessed at weeks 2 and 4 of the treatment phase.

Statistics

Differences between groups in number and percentage of subjects who flared were analyzed using the Fisher exact test. Significant difference in time to flare between groups was calculated using the log-rank test. Change in ADSI scores between baseline, week 2, and week 4 of the treatment phase and between groups were tested for significance using the Wilcoxon signed rank test.
Global tolerability data analysis compared favorable (excellent and good) vs unfavorable (fair and poor) tolerability using a binomial (sign) test (null hypothesis). All statistical tests were 2-sided at a significance level α of .05 and were performed using SAS software version 9.3 (SAS Institute, Cary, NC).

RESULTS

Of the 45 subjects who were enrolled at baseline, 43 completed the study. Two subjects who flared discontinued during the treatment phase (Figure 2). Subjects ranged in age from 7 months to 11 years 5 months (mean, 3.5 years) (Table 1).
