Beneficial effects of an alkaline topical treatment in patients with mild atopic dermatitis

Atopic dermatitis (AD) is the most common cause of eczema. The skin condition affects millions of people worldwide. Severe cases of AD demand systemic treatment, but most AD cases rely on local therapy with topical corticosteroids, emollients, and moisturizing agents to alleviate eczema. Commonly, derma-cosmetics with a pH around 5.5 are used to treat eczematous lesions (EL). However, evidence is currently amassing that the use of mildly alkaline topical creams is beneficial for AD-related eczema treatment because of its effect on the inflammation in the skin.

To test an alkaline two-phase care concept for the treatment of eczema.

An open-label study of 25 patients with eczema associated with mild AD. Patients were treated with Alkaline Build Up Caring Cream INTENSIVE and Alkaline Build Up Caring Cream PLUS+ (both Siriderma^® ) for eight weeks. Dermatological, biochemical, and questionnaire-based examinations were conducted prior to the trial and after its completion.

Topical administration of slightly alkaline creams led to small and statistically insignificant increases of skin pH. Clinical examination at the end of the observation period revealed a significant decrease of total eczematous-affected skin area, a significant decrease in average severity scores of EL, and significant improvements in patient-reported outcome parameters. Blood tests did not reveal any significant changes, except for small but significant increases in IL-8 and monocytes.

Mildly alkaline topical creams seem to provide soothing effects on eczema-related skin inflammation and thus might contribute to treatment of local symptoms of eczema in patients with mild AD.
