Evaluation of a Combination of Two Medical Devices and One Device Use in the Treatment of Toenail Onychomycosis

Onychomycosis is a fungal infection of the nail apparatus that causes discoloration, thickening, and separation from the nail bed. It is primarily caused by dermatophytes, which are infectious fungi that feed on the keratin present in the skin, hair and nails. Onychomycosis has several clinical presentations, including distal and lateral subungual onychomycosis which is the most common form, proximal subungual onychomycosis, superficial white onychomycosis, and total dystrophic onychomycosis. Onychomycosis affects toenails more often than fingernails because of their slower growth, reduced blood supply, and frequent confinement in dark, moist environments. (1) The severity of onychomycosis can be described as mild, moderate, or severe. Published studies will assign a label of mild-moderate disease if less than approximately 60% of the nail is showing symptoms. Onychomycosis is the most common nail infection worldwide occurring in 10% of the general population but is more common in older adults. Despite treatment, the recurrence rate of onychomycosis is 10% to 50% as a result of reinfection or lack of mycotic cure. Topical drugs for onychomycosis generally come in the form of lacquers or solutions directly applied to the surface of the nail. The principal aim of this study is to evaluate the efficacy of the tested products in medium to moderate onychomycosis after 112 days of treatments. For this study, 44 patients (22 patients per group) presenting at least one infected toenail will be included to reach this objective.
