[New aspects in treatment of systemic mycoses].

The incidence of systemic fungal infection has been increasing during the last two decades. Candida and Aspergillus spp. are the classical opportunistic pathogens. Rare fungi, such as Mucor, Rhizopus, Fusarium, Trichosporon, Paecilomyces, Alternaria, Cladosporium and Pseudoallescheria, are emerging as cause of systemic fungal infection in the immunocompromised host. For more than 40 years Amphotericin B has been the gold standard of antifungal treatment because of its broad spectrum comprising yeasts, dimorphic fungi and moulds. Its nephrotoxicity has led to the development of lipid-associated preparations of amphotericin B: liposomal amphotericin B, amphotericin B colloidal dispersion and amphotericin B lipid complex. These preparations are less nephrotoxic, but higher doses than those of conventional amphotericin B are needed to achieve the same effect. The triazole fluconazole is the treatment of choice in infections caused by Candida albicans. New antifungal compounds are voriconazole and the candins, the pradimicin/benanomycin family, nikkomycin Z and a liposomal preparation of nystatin.
