  • imageSystemic mycoses can be caused by pathogenic fungi and include histoplasmosis, coccidioidomycosis, cryptococcosis, blastomycosis, paracoccidioidomycosis, and sporotrichosis, or infections by opportunistic fungi such as Candida albicans, Aspergillus species, Trichosporon, Candida glabrata, Fusarium, Alternaria, and Mucor.

  • imageThe diagnosis of fungal infection is accomplished by careful evaluation of clinical symptoms, results of serologic tests, and histopathologic examination and culture of clinical specimens. Rapid, accurate diagnostic laboratory tests are currently under development.

  • imageHistoplasmosis is caused by Histoplasma capsulatum and is endemic in parts of the central United States along the Ohio and Mississippi River valleys, and in Central and South America. Although most patients experience asymptomatic infection, some can experience chronic, disseminated disease.

  • imageAsymptomatic patients with histoplasmosis are not treated, while patients with evident disease are treated with either oral itraconazole or an IV amphotericin B lipid formulation.

  • imageBlastomycosis is caused by Blastomyces dermatitidis. In the immunocompetent host, acute pulmonary blastomycosis can be mild and self-limited and may not require treatment. However, consideration should be given to treating all infected individuals to prevent extrapulmonary dissemination. All persons with moderate-to-severe pneumonia, disseminated infection, or those who are immunocompromised require antifungal therapy.

  • imageCoccidioidomycosis is caused by Coccidioides immitis and Coccidioides posadasii and is endemic in some parts of the southwestern United States. It can cause nonspecific symptoms, acute pneumonia, or chronic pulmonary or disseminated disease. Primary pulmonary disease (unless severe) frequently is not treated, whereas disseminated and meningeal disease is treated with fluconazole.

  • imageCryptococcosis is caused by Cryptococcus neoformans, which occurs primarily in immunocompromised patients, and Cryptococcus gattii, which occurs primarily in nonimmunocompromised patients. Patients with acute meningitis are treated with lipid formulations of amphotericin B with flucytosine. Patients infected with human immunodeficiency virus (HIV) often require long- term suppressive therapy with fluconazole or itraconazole.

  • imageA variety of Candida species (including C. albicans, C. glabrata, Candida tropicalis, Candida parapsilosis, and Candida krusei) can cause diseases such as mucocutaneous, oral, esophageal, vaginal, and hematogenous candidiasis, as well as candiduria. Candidemia can be treated with a variety of antifungal agents; the optimal choice depends on previous patient exposure to antifungal agents, potential drug interactions and toxicities of each agent, and local epidemiology of intensive care unit (ICU) or hematology–oncology centers.

  • imageAspergillosis can be caused by a variety of Aspergillus species that can cause superficial infections, pneumonia, allergic bronchopulmonary aspergillosis (BPA), or invasive infection. Voriconazole has emerged as the drug of choice of most clinicians for primary therapy of most patients with invasive aspergillosis (IA). Combination therapy may be considered in cases of severe infection, especially in patients with persistent neutropenia.
