Fungemia is the presence of fungi 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.[1] 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 immunocompromisedpatients with severe neutropenia, cancer patients, or in patients with intravenous catheters. It has been suggested that otherwise immunocompetent patients taking infliximab may also be at a higher risk.
Symptoms can range from mild to extreme—often described as extreme flu-like symptoms. Many symptoms may be associated with fungemia, including pain, acute confusion, chronic fatigue, and infections. Skin infections can include persistent or non-healing wounds and lesions, sweating, itching, and unusual discharge or drainage.[citation needed]
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.[4]
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.[5] 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.[6] 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.[7]
Diagnosis
The gold standard for the diagnosis of invasive candidiasis and candidemia is a positive culture. Blood cultures should be obtained in all patients with suspected candidemia.[8]
Treatment
Neutropenic vs non-neutropenic candidemia is treated differently.[9]
