[Treatment of interdigital foot Erythrasma with ozonated olive oil].

BACKGROUND: Erythrasma is caused by Corinebacterium minutissimum producing a porphyrin that with Wood's light emits a coral-red fluorescence. It is the most common bacterial infection of the feet. Ozonated olive oil decreases the cytoplasm and damages bacterial proteins and lipids. Treatment is with oral erythromycin and there is no consensus regarding the topical therapy of choice. The aim of this paper is to evaluate the therapeutic efficacy of ozonated olive oil in a pilot trial for Erythrasma.

METHODS: Experimental, open, observational, descriptive, longitudinal clinical trial at the section of Mycology, of the General Hospital "Dr. Manuel Gea González".

PATIENTS: 10 individuals with interdigital feet Erythrasma.

INTERVENTION: ozonated olive oil every 12 hours for 10 days was given.

RESULTS: All patients had disappearance of coral-red fluorescence, erythema, fissures, pruritus, and maceration; two patients persisted with scaling. A cure was obtained in 100 % of patients, similar to oral erythromycin response.

CONCLUSIONS: Ozonated olive oil is a good topical treatment option for interdigital Erythrasma avoiding oral medications. Larger studies are required.
