Saccharomyces boulardii induced sepsis: Successful therapy with voriconazole after treatment failure with fluconazole

Saccharomyces boulardii is frequently used for prevention and treatment of all forms of diarrhoea. We report the case of a 19-y-old white male with an underlying severe neurological disease, who developed a fungal sepsis after prophylactic application of a drug containing S. boulardii. Initial treatment with fluconazole was not successful. After the application of voriconazole, the sepsis resolved completely. This is the first clinical report of a successful treatment of Saccharomyces sepsis with voriconazole.
