An Emollient Containing Aquaphilus dolomiae Extract is Effective in the Management of Xerosis and Pruritus: An International, Real-World Study

INTRODUCTION: Xerosis and pruritus are common manifestations of numerous dermatologic and systemic diseases. We evaluated the effectiveness of an emollient containing an Aquaphilus dolomiae extract (ADE-G1) for the management of pruritus and xerosis in patients of all age with a range of dermatologic and systemic diseases. METHODS: This open-label, real-world study involved 5910 patients from 33 European, South American, Asian, and North and South African countries, who applied the product for 7 days twice daily to the face and body after the skin had been cleansed and dried. The physician assessed xerosis severity and patients assessed pruritus severity, the duration of itch, sleep quality, and the impact of their skin disease on their quality of life, using scales derived from the SCORing Atopic Dermatitis (SCORAD) index and questionnaires, at inclusion and after 7 days of use. RESULTS: The 7-day care regimen resulted in 56% and 60% reductions in xerosis and pruritus severity, respectively, regardless of the underlying pathology (p < 0.0001), with the largest decreases observed for patients with ichthyosis for xerosis and for patients post scabies treatment for pruritus. The mean sleep disturbance and mean total Dermatology Life Quality Index (DLQI) scores were also reduced by 58% and 60% (p < 0.0001), respectively. The emollient was effective whether the product was used alone or in combination with topical or systemic treatments and was well tolerated. CONCLUSION: Our study shows that the 7-day regimen with the emollient was a universally effective treatment for pruritus and xerosis, regardless of the underlying pathology.
