Abstract
Background: Ectoine is a widespread osmolyte enabling halophilic bacteria to withstand high osmotic stress that has many potential applications ranging from cosmetics to its use as a therapeutic agent. Objective: The aim of this study was to compare the efficacy and tolerability of ectoine 1% and hyaluronic acid 0.1% containing (EHA) cream with a vehicle cream in children with mild-to-moderate atopic dermatitis (AD). Methods: A randomized, controlled, observer-blind, multicenter clinical trial was conducted in children aged 2–18 years, diagnosed with mild-to-moderate AD (SCORAD ≤20). Patients were randomized to either receiving EHA cream or vehicle cream twice daily for 4 weeks. The primary outcome measure was the mean change in objective SCORAD from baseline to the final visit. The secondary outcome measures included the mean change in Investigator's Global Assessment score, patient's judgment of efficacy and patient's assessment of pruritus. Safety of EHA cream was also assessed. Results: A total of 70 patients (35 in each group) were randomized and 57 were included in the final analysis set. Based on SCORAD measurements, patients using EHA cream achieved superior clinical improvement compared to the control group at 28 days (p <.001). EHA cream was also superior to the vehicle cream regarding all secondary outcome measures. Eight (23.5%) patients receiving EHA cream and two (5.7%) patients receiving vehicle cream experienced mild cutaneous adverse events (AEs). Conclusions: In children 2–18 years old with mild-to-moderate AD, EHA cream was superior to vehicle cream, with minor AEs. © 2022 Wiley Periodicals LLC.
