Opportunistic fungal infections are becoming more frequent complications during cancer therapy, after organ transplantation and in AIDS infections, especially after better control of bacterial infections in immunocompromised patients. Periods of prolonged neutropenia with neutrophil count less than 0.5 x 10(9)/L longer than 7 days, are the most important risk factors for the development of systemic fungal infections. Especially susceptible are the patients during treatment of acute leukemia, or after bone marrow transplantation. The most frequent causing agents of systemic fungal infections are Candida and Aspergillus species, than Cryptococcus neoformans and Mucor. Some other unusual species such Fusarium, Trichosporon, non-albicans Candida species of Candida are becoming more frequent, and is frequently resistant to conventional therapy. The difficulties in early and precise diagnosis of fungal infections, and the lack of adequate and efficient drugs are responsible for the high mortality of immunocompromised patients, even in potentially curable diseases. The recognition of risk factors, introduction of prophylactic measures, application of empirical antifungal therapy, are the procedures for the reduction of morbidity and mortality of invasive fungal infections. Fluconazole administration in prevention of systemic fungal infections, has become the standard approach, especially after bone marrow transplantation, while the oral itraconazole solution, has even more extended activity. Fluconazole appears successful also in the treatment of systemic Candidiasis. Conventional amphotericin-B is still the "gold standard" in the treatment of fungal infections. The new lipid formulations of amphotericin-B, intravenous itraconazole, has an identical efficacy, but are less toxic than conventional amphotericin-B. Several new promising agents are in the stage of clinical investigation like voriconazole, caspofungin, mycafungin and some other.
