A novel treatment of diaper dermatitis in children and adults.

BACKGROUND Diaper dermatitis (DD) is an acute inflammatory reaction, regardless of the cause, of the diaper-covered area. Topical skin barrier repair cosmetic products are the mainstay treatment to cure and/or prevent DD. AIMS To assess the efficacy/tolerability of a zinc gluconate-taurine/zinc oxide and panthenol/ glycerin/ Butyrospermum parkii butter barrier cream using clinical evaluation. METHODS In this prospective, open-label trial, 20 patients (10 infants/10 adults), with mild/moderate DD enrolled at the Dermatology University Clinic of Catania (Italy) were instructed to apply the cream twice daily for 30 days. Degree of erythema was performed clinically by a 5-point severity scale (from 0 = no erythema to 4 = severe erythema), at baseline, at 15 and 30 days. An Investigator Global Assessment (IGA) using a 6-point scale (from -1 = worsening to 4 = complete response/clear) along with product tolerability was also performed at 15 and 30 days. Statistical analysis was performed using SAS version 9. RESULTS At 15 days, a reduction of clinical erythema assessment (CEA) from baseline was observed (mean from 3.2 ± 0.8 to 2.5 ± 0.3; p < 0.06), that although nonsignificant, showed a significant progressive improvement at 30 days (mean from 3.2 ± 0.8 to 1.1 ± 0.9; p < 0.0001) without any age differences. CONCLUSIONS Our preliminary results indicate that the tested barrier cream may represent a promising approach in DD rash. It may be used in mild-to-moderate forms in monotherapy without significant side effects or, where required, in association with pharmacological agents. Its long-term use is likely safe.
