An innovative oat-based sterile emollient cream in the maintenance therapy of childhood atopic dermatitis.

ABSTRACT

Although emollients are recommended in the management of atopic dermatitis (AD), regimens for emollient maintenance therapy are awaiting validation. We conducted an international, multicenter, open-label trial to assess the effects of a 3-month maintenance treatment regimen with a sterile, preservative-free emollient cream containing oat plantlets in children (ages 6 mos-6 yrs) with moderate AD. After a 14-day run-in stabilization phase using a topical corticosteroid (TCS) treatment of medium potency, 108 children with a SCORing Atopic Dermatitis (SCORAD) index of 20 or less were included in the study. Emollient was applied twice daily for 3 months. Rescue TCS treatment was used only in cases of flare-ups. The SCORAD index, Patient-Oriented SCORAD (PO-SCORAD) index, number of flares, TCS use, and tolerance were assessed at months 1, 2, and 3 (M1, M2, M3). AD severity improved, with a highly significant decrease in the SCORAD and PO-SCORAD indexes at M2 and M3 (p < 0.001). Changes from baseline to M3 were 48.6 ± 73.6% for SCORAD and 29.6 ± 125.3% for PO-SCORAD. The number of flares and TCS use significantly decreased by M3 (both p < 0.001). Very good tolerance was recorded in 100% of children at M2 and M3. Notwithstanding the limitations inherent in open-label trials, twice daily application of the oat-based sterile emollient cream led to a significant improvement of clinical symptoms, evidenced by parallel changes in the SCORAD and PO-SCORAD indexes and fewer flare-ups. Clinical benefit and less TCS use were maintained at M3. Tolerance was very good.
