Treatment Of Cradle Cap In Infants With A New Cosmetic Non-Steroidal Gel Cream: Clinical, Laboratory, And Instrumental Evaluation

Background Cradle cap is a benign and self-limiting variant of seborrheic dermatitis (SD) that can be distressing for parents.Aims To assess by clinical/laboratory/instrumental evaluation the efficacy/tolerability of a gel cream containing piroctone olamine (antifungal), biosaccharide gum-2 (antifungal), stearyl glycyrrhetinate (anti-inflammatory), and zinc l-pyrrolidone carboxylate (zinc-PCA) (antiseborrheic) in the treatment of mild/ moderate cradle cap.Methods In this prospective, open-label trial, 10 infants, with mild/moderate cradle cap enrolled at the Dermatology University Clinic of Catania (Italy) used the tested gel cream twice daily for 30 days. Degree of erythema was evaluated clinically by a 5-point severity scale (from 0=no erythema to 4=severe erythema), at baseline, at 15 and 30 days. Desquamation was rated by dermoscopy evaluation using a 5-point scale (from 0=no desquamation to 4=severe/many large adherent white flakes), at all time points. An Investigator Global Assessment (IGA) using a 6-point scale (from -1=worsening to 4=complete response/clear) was also performed at 30 days. Five subjects, randomly selected, underwent double microbiological evaluation for bacteria and yeasts by cultures of cotton swabs at baseline and at 30 days. Tolerability/acceptability was evaluated on a 4-point scale (from 0=very poor to 3=excellent) at 15 and 30 days. Data were processed using SAS version 9.Results At baseline, a significant colony-forming unit (CFU) count for Malassezia furfur and Staphylococcus aureus was detected in 4 out of 5 selected patients. After 15 and 30 days, a statically significant reduction from baseline in erythema and desquamation severity was observed, along with a reduction in CFU count for Malassezia furfur and Staphylococcus aureus from baseline. No signs of local side effects were documented.Conclusions Our results indicate that the tested gel cream may represent a valid option to treat mild-to-moderate forms of cradle cap and support its antifungal and antibacterial properties.
