Evaluation of a topical anti-inflammatory/antifungal combination cream in mild-to-moderate facial seborrheic dermatitis: An intra-subject controlled trial examining treated vs. Untreated skin utilizing clinical features and erythema-directed digital photography

Objective: To evaluate if nonprescription topical agents may provide positive outcomes in the management of mild-tomoderate facial seborrheic dermatitis by reducing inflammation and scale production through clinical evaluation and erythema-directed digital photography. Setting: Open-label, prospective, not-blinded, intra-patient, controlled, clinical trial (target area). Participants: Twenty adult subjects affected by mild-to-moderate facial seborrheic dermatitis were enrolled and instructed to apply the study cream two times daily, initially on a selected target area only for seven days. If the subject developed visible improvement, it was advised to extend the application to all facial affected area for 21 additional days. Measurement: Efficacy was evaluated by measuring the grade of erythema (by clinical examination and by erythemadirected digital photography), desquamation (by clinical examination), and pruritus (by subject-completed visual analog scale). Additionally, at the end of the protocol, a Physician Global Assessment was carried out. Results: Eighteen subjects completed the study, whereas two subjects were lost to follow-up for nonadherence and personal reasons, respectively. Day 7 data from target areas showed a significant reduction in erythema. At the end of study, a significant improvement was recorded for erythema, desquamation, and pruritus compared to baseline. Physician Global Assessment showed improvement in 89 percent of patients, with a complete response in 56 percent of cases. Conclusion: These preliminary results indicate that the study cream may be a viable nonprescription therapeutic option for patients affected by facial seborrheic dermatitis able to determine early and significant improvement. This study also emphasizes the advantages of using an erythema-directed digital photography system for assisting in a simple, more accurate erythema severity grading and therapeutic monitoring in patients affected by seborrheic dermatitis.
