Scalp Microbiome Dynamics Can Contribute to the Clinical Effect of a Novel Antiseborrheic Dermatitis Shampoo Containing Patented Antifungal Actives: A Randomized Controlled Study.
Introduction: Scalp seborrheic dermatitis (SD) can cause physical discomfort and social embarrassment in affected individuals. Mild-to-moderate scalp SD can be managed using topical products with antifungal, antiinflammatory, and keratolytic properties.
Methods: A two-phase, randomized, controlled study was conducted to evaluate the clinical efficacy of a newly formulated anti-SD shampoo containing two patented antifungal actives and to investigate the associated changes in the scalp microbiota. The intervention involved a 2-week intensive phase for the 42 subjects included in the study, consisting of the application of the anti-SD shampoo three times a week; a randomized [1:1], controlled, parallel-group 8-week maintenance phase consisting of the test group applying the study shampoo once a week alternately with a neutral shampoo twice a week; and the control group applying the neutral shampoo alone three times a week.
Results: Following the intensive phase, the scalp condition improved substantially, as evidenced by a significant decrease in the severity of dandruff, erythema, and pruritus, associated with an improvement of SD dysbiosis. These improvements were more sustained in the test group than in the control group during the maintenance phase. The rediversification of the scalp microbiota involved a significant increase in fungal and bacterial richness along with a decrease in the level of SD-predominant Malassezia fungi and Staphylococcus bacteria and an increase in the level of low-abundant fungi genera belonging to the Ascomycota phylum.
Conclusions: The synergistic effects of antimycotic and antiinflammatory agents in the study shampoo likely contributed to rebalancing the fungal and bacterial ecosystem, thus improving scalp symptoms.
Clinicaltrials:
Gov identifier: NCT06578962 (retrospectively registered on 28 August 2024).
期刊介绍：
Dermatology and Therapy is an international, open access, peer-reviewed, rapid publication journal (peer review in 2 weeks, published 3–4 weeks from acceptance). The journal is dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of dermatological therapies. Studies relating to diagnosis, pharmacoeconomics, public health and epidemiology, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to all clinical aspects of dermatology, such as skin pharmacology; skin development and aging; prevention, diagnosis, and management of skin disorders and melanomas; research into dermal structures and pathology; and all areas of aesthetic dermatology, including skin maintenance, dermatological surgery, and lasers.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols, and short communications. Dermatology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an International and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. The journal appeals to a global audience and receives submissions from all over the world.
