Fungal infections have been recognized as major cause of morbidity and mortality in neutropenic and non-neutropenic surgical intensive care patients. The incidence of Candida has increased: it is now the fourth most often isolated pathogen in bloodstream infections. The incidence of Aspergillus infection in transplant patients is highest in heart and lung transplants: 19-26%. ⋯ This has lead to treatment failures in severe Candida and Aspergillus infections. The prognosis for invasive Aspergillus infections remains poor despite amphotericin B treatment. Newer azoles, e.g. voriconazole, demonstrated stable activity against most of these strains and may offer an option in the treatment of refractory fungal infections.

The past two decades have witnessed an increase in serious fungal infections, without corresponding growth in available antifungal agents. Voriconazole (VRC) is a novel triazole antifungal, recently approved in Europe for treatment of serious infections caused by Aspergillus, Fusarium, Scedosporium, and resistant Candida species. Voriconazole has in vitro activity against yeasts and yeast-like fungi similar, or superior to, fluconazole (FLC), itraconazole (ITC) and amphotericin B (AMB). ⋯ Most importantly, well-designed human clinical trials have confirmed the efficacy of VRC in the treatment of candidal esophagitis, IA, and febrile neutropenia. Smaller studies and case reports have shown VRC is useful for salvage therapy of IA, cerebral aspergillosis, Scedosporium, and other fungal infections. Clinical testing has shown VRC is safe and well tolerated; the most common side effect is benign, self-limited visual disturbance.
