Abstract
Vulvovaginal candidiasis (VVC) and recurrencies are common in reproductive-aged women. The emergence of Candida strains resistant to conventional antimycotic drugs prompted the search for alternative therapies. Hyaluronic acid (HA), a uniform and linear glycosaminoglycan, has been proposed as an anti-Candida agent. Vaginal lactobacilli and their derivatives, including cell free culture supernatants (CFS), represent potential strategies for the treatment of Candida infections. In the present paper, the anti-Candida potential of HA and lyophilised CFS (LCFS), obtained from the vaginal strain Lactobacillus crispatus BC5, was investigated. HA and LCFS proved to be active towards a panel of clinical Candida isolates belonging to different species in a dose dependent manner and their association maintained the antifungal activity. Notably, also Candida species generally resistant to conventional antifungals resulted sensitive. A vaginal matrix based on microcrystalline cellulose and containing effective doses of both agents was developed and characterised. This vaginal formu-lation showed mucoadhesive ability and almost abrogated Candida albicans growth. In conclusion, HA and LCFS from L. crispatus BC5 are thus good candidates to design a new therapeutic strategy to counteract VVC, and the proposed vaginal matrix represents a promising prototype.File | Dimensione | Formato | |
