Fungemia is the presence of fungus or yeast in the blood. The most common type, also known as candidemia, candedemia, or systemic candidiasis, is caused by Candida species. Candidemia is also among the most common bloodstream infections of any kind. Infections by other fungi, including Saccharomyces, Aspergillus (as in aspergillemia, also called invasive aspergillosiis) and Cryptococcus, are also called fungemia. It is most commonly seen in immunosuppressed or immunocompromised with severe neutropenia, oncology patients, or in patients with intravenous . It has been suggested that otherwise immunocompetent patients taking infliximab may also be at a higher risk.
Diagnosis is difficult, as routine have poor sensitivity.
Candida auris is an emerging multidrug-resistant (MDR) yeast that can cause invasive infections and is associated with high mortality. It was first described in 2009 after being isolated from external ear discharge of a patient in Japan. Since the 2009 report, C. auris infections, specifically fungemia, have been reported from South Korea, India, South Africa, and Kuwait. Although published reports are not available, C. auris has also been identified in Colombia, Venezuela, Pakistan, and the United Kingdom.
In a single reported instance, Psilocybe cubensis was reported to have been cultured from a case of fungemia in which an individual self-injected an underprocessed decoction of fungal matter. The patient, who had been experiencing depression, attempted to self-medicate with the mushrooms but was frustrated by the lag time between eating the mushrooms and experiencing the psychedelic effects. In an attempt to bypass this, the patient boiled and filtered the mushrooms into a 'mushroom tea' which was then administered by injection. The patient had multiple organ failure, but this was successfully reversed and the infection treated with antifungal drugs. Two other examples of fungemia as a result of injecting fungal matter in this way have been described in medical literature, both dating to 1985.
An intravenous echinocandin such as anidulafungin, caspofungin or micafungin is recommended as first-line therapy for fungemia, specifically candidemia. Oral or intravenous fluconazole is an acceptable alternative. The lipid formulation amphotericin B is a reasonable alternative if there is limited antifungal availability, antifungal resistance, or antifungal intolerance.
