Abstract:
Background:Topical corticosteroids are the mainstay of treatment for patients with atopic dermatitis. However,
adverse effects associated with long-term steroid use often limit its use. This interventional study
compared the efficacy of a proprietary moisturiser containing licochalcone A, omega-6 fatty acids,
and ceramide 3 against 1% hydrocortisone cream in treating patients with mild-to-moderate atopic
dermatitis.
Methods:Patients with mild-to-moderate atopic dermatitis affecting either the cubital fossa or popliteal fossa symmetrically were given twice-daily applications of the moisturiser and hydrocortisone on opposite sides of the body and monitored for a total of three weeks in a non-randomised half body, doubleblind study. Hydrocortisone was switched to aqueous cream after two weeks, whereas the application of the moisturiser continued until study completion. The assessment of SCORing Atopic Dermatitis (SCORAD) index and Dermatology Life Quality index was performed at baseline and every subsequent follow-up visit to measure patients’ response to treatment.
Results:The licochalcone A (LA) moisturiser and 1% hydrocortisone (HC) cream both demonstrated significant reduction in sign and symptom scores after only 1 week of treatment (percentage of reduction in sign and symptom scores: 52.8% [LA] vs 58.5% [HC]). Further reduction in mean sign and symptom scores for both treatments was observed at week 2 (61.3% [LA] vs 56.8% [HC]) and also at week 3 when HC was switched to aqueous cream (70.5% [LA] vs 63.5% [HC→aqueous cream]) (p<0.001 vs baseline within the same treatment arm at weeks 1, 2 and 3). When comparing the mean difference in SCORAD index for both individual as well as total skin signs and symptoms between LA and HC (i.e. inter-arm comparison), there was no significant difference between the two treatments for all the assessed parameters. Patients reported improvements in itching, sleeplessness, and overall quality of life over the course of treatment.
Conclusion:The licochalcone A moisturiser can be considered as an effective steroid-sparing alternative to topical corticosteroids in managing mild-to-moderate atopic dermatitis. - Full text:15.2021my0017.pdf
