Key Points
- Invasive infection due to Candida species is largely a condition associated with medical progress and is widely recognized as a major cause of morbidity and mortality in the healthcare environment.
- There are at least 15 distinct Candida species that cause human disease, but over 90% of invasive disease is caused by the 5 most common pathogens, C. albicans, C. glabrata, C. tropicalis, C. parapsilosis, and C. krusei.
- Each of these organisms has unique virulence potential, antifungal susceptibility, and epidemiology.
- Taken as a whole, significant infections due to these organisms are generally referred to as “invasive candidiasis,” except for mucosal Candida infections, especially those involving the oropharynx, esophagus and vagina, which are not considered to be classically invasive disease.
Management
I. Candidemia in Non-Neutropenic Patients
- An echinocandin (caspofungin, loading dose 70 mg, then 50 mg daily; micafungin, 100 mg daily; anidulafungin, loading dose 200 mg, then 100 mg daily) is recommended as initial therapy (S/H).
- Fluconazole, intravenous or oral, 800 mg (12 mg/kg) loading dose, then 400 mg (6 mg/kg) daily is an acceptable alternative to an echinocandin as initial therapy in selected patients, including those who are not critically ill and who are considered unlikely to have a fluconazole resistant Candida species (S/H).
- Testing for azole susceptibility is recommended for all bloodstream and other clinically relevant Candida isolates. Testing for echinocandin susceptibility should be considered in patients who have had prior treatment with an echinocandin and among those who have infection with C. glabrata or C. parapsilosis (S/L).
- Transition from an echinocandin to fluconazole (usually within 5-7 days) is recommended for patients who are clinically stable, have isolates that are susceptible to fluconazole (e.g.,C. albicans), and have negative repeat blood cultures following initiation of antifungal therapy (S/M).
- For infection due to C. glabrata, transition to higher-dose fluconazole 800 mg (12 mg/kg) daily or voriconazole 200-300 mg (3-4 mg/kg)
twice daily should be considered only among patients with fluconazole-susceptible or voriconazole-susceptible isolates (S/L). - Lipid formulation amphotericin B (AmB) (3-5 mg/kg daily) is a reasonable alternative if there is intolerance, limited availability, or resistance to other antifungal agents (S/H).
- Transition from AmB to fluconazole is recommended after 5-7 days among patients who have isolates that are susceptible to fluconazole, who are clinically stable, and in whom repeat cultures on antifungal therapy are negative (S/H).
- Among patients with suspected azole and echinocandin-resistant Candida infections, lipid formulation AmB (3-5 mg/kg/d) is recommended (S/L).
- Voriconazole 400 mg (6 mg/kg) twice daily for 2 doses, then 200 mg
(3 mg/kg) twice daily is effective for candidemia but offers little advantage over fluconazole as initial therapy. (S/M). Voriconazole is recommended as step-down oral therapy for selected cases of candidemia due to C. krusei (S/L). - All non-neutropenic patients with candidemia should have a dilated ophthalmological examination, preferably performed by an ophthalmologist, within the first week after diagnosis (S/L).
- Follow-up blood cultures should be performed every day or every other day to establish the time point at which candidemia has been cleared (S/L).
- Recommended duration of therapy for candidemia without obvious metastatic complications is for 2 weeks after documented clearance of Candida species from the bloodstream and resolution of symptoms attributable to candidemia (S/M).
II. Central Venous Catheters (CVCs) in Non-Neutropenic Patients with Candidemia
- CVCs should be removed as early as possible in the course of candidemia when the source is presumed to be the CVC and the catheter can be removed safely. This decision should be individualized for each patient (S/M).
III. Candidemia in Neutropenic Patients
- An echinocandin (caspofungin, loading dose 70 mg, then 50 mg daily; micafungin, 100 mg daily; anidulafungin, loading dose 200 mg, then 100 mg daily) is recommended as initial therapy (S/M).
- Lipid formulation AmB, 3-5 mg/kg daily, is an effective but less attractive alternative because of the potential for toxicity (S/M).
- Fluconazole, 800 mg (12 mg/kg) loading dose, then 400 mg (6 mg/kg) daily, is an alternative for patients who are not critically ill and have had no prior azole exposure (W/L).
- Fluconazole, 400 mg (6 mg/kg) daily, can be used for step-down therapy during persistent neutropenia in clinically stable patients who have susceptible isolates and documented bloodstream clearance (W/L).
- Voriconazole, 400 mg (6 mg/kg) twice daily for 2 doses, then 200-300 mg (3-4 mg/kg) twice daily, can be used in situations in which additional mold coverage is desired (W/L). Voriconazole can also be used as step-down therapy during neutropenia in clinically stable patients who have had documented bloodstream clearance and isolates that are susceptible to voriconazole (W/L).
- For infections due to C. krusei, an echinocandin, lipid formulation AmB, or voriconazole is recommended (S/L).
- Recommended minimum duration of therapy for candidemia without metastatic complications is 2 weeks after documented clearance of Candida from the bloodstream, provided neutropenia and symptoms attributable to candidemia have resolved (S/L).
- Ophthalmological findings of choroidal and vitreal infection are minimal until recovery from neutropenia. Therefore, dilated fundoscopic examinations should be performed within the first week after recovery from neutropenia (S/L).
- In the neutropenic patient, sources of candidiasis other than a central venous catheter (e.g., gastrointestinal tract) predominate. Catheter removal should be considered on an individual basis (S/L).
- G-CSF-mobilized granulocyte transfusions can be considered in cases of persistent candidemia with anticipated protracted neutropenia (W/L).
IV. Chronic Disseminated (Hepatosplenic) Candidiasis
- Initial therapy with lipid formulation AmB, 3-5 mg/kg daily OR an echinocandin (micafungin 100 mg daily, caspofungin, 70 mg loading dose, then 50 mg daily, or anidulafungin, 200 mg loading dose, then 100 mg daily), for several weeks is recommended, followed by oral fluconazole, 400 mg (6 mg/kg) daily, for patients who are unlikely to have a fluconazole-resistant isolate (S/L).
- Therapy should continue until lesions resolve on repeat imaging, which is usually several months. Premature discontinuation of antifungal therapy can lead to relapse (S/L).
- If chemotherapy or hematopoietic cell transplantation is required, it should not be delayed because of the presence of chronic disseminated candidiasis, and antifungal therapy should be continued throughout the period of high risk to prevent relapse (S/L).
- For patients who have debilitating persistent fevers, short term
(1-2 weeks) treatment with non-steroidal anti-inflammatory drugs or corticosteroids can be considered (W/L).
V. Empirical Treatment for Suspected Invasive Candidiasis in Non-Neutropenic Patients in the Intensive Care Unit (ICU)
- Empirical antifungal therapy should be considered in critically ill patients with risk factors for invasive candidiasis and no other known cause of fever and should be based on clinical assessment of risk factors, surrogate markers for invasive candidiasis and/or culture data from non-sterile sites (S/M). Empirical antifungal therapy should be started as soon as possible in patients who have the above risk factors and who have clinical signs of septic shock (S/M).
- Preferred empirical therapy for suspected candidiasis in non-neutropenic patients in the ICU is an echinocandin (caspofungin, loading dose of 70 mg, then 50 mg daily; micafungin, 100 mg daily; anidulafungin, loading dose of 200 mg, then 100 mg daily) (S/M).
- Fluconazole, 800 mg (12 mg/kg) loading dose, then 400 mg (6 mg/kg) daily, is an acceptable alternative for patients who have had no recent azole exposure and are not colonized with azole resistant Candida species (S/M).
- Lipid formulation AmB, 3-5 mg/kg daily, is an alternative if there is intolerance to other antifungal agents (S/L).
- Recommended duration of empirical therapy for suspected invasive candidiasis in those patients who improve is 2 weeks, the same as for treatment of documented candidemia (W/L).
- For patients who have no clinical response to empirical antifungal therapy at 4-5 days and who do not have subsequent evidence of invasive candidiasis after the start of empirical therapy or have a negative non-culture-based diagnostic assay with a high negative predictive value, consideration should be given to stopping antifungal therapy (S/L).
VI. Prophylaxis to Prevent Invasive Candidiasis in the ICU Setting
- Fluconazole, 800 mg (12 mg/kg) loading dose, then 400 mg (6 mg/kg) daily, could be used in high-risk patients in adult ICUs with a high rate (>5%) of invasive candidiasis (W/M).
- An alternative is to give an echinocandin (caspofungin, 70 mg loading dose, then 50 mg daily; anidulafungin 200 mg loading dose and then 100 mg daily; or micafungin, 100 mg daily) (W/L).
- Daily bathing of ICU patients with chlorhexidine, which has been shown to decrease the incidence of bloodstream infections including candidemia, could be considered (W/M).
VII. Neonatal Candidiasis, including Central Nervous System Infection
Invasive Candidiasis and Candidemia
- AmB deoxycholate, 1 mg/kg daily, is recommended for neonates with disseminated candidiasis (S/M).
- Fluconazole, 12 mg/kg IV or oral daily, is a reasonable alternative in patients who have not been on fluconazole prophylaxis (S/M).
- Lipid formulation AmB, 3-5 mg/kg daily, is an alternative, but should be used with caution, particularly in the presence of urinary tract involvement (W/L).
- Echinocandins should be used with caution and generally limited to salvage therapy or to situations in which resistance or toxicity preclude the use of AmB deoxycholate or fluconazole (W/L).
- A lumbar puncture and a dilated retinal examination are recommended in neonates with cultures positive for Candida species from blood and/or urine (S/L).
- CT or ultrasound imaging of the genitourinary tract, liver, and spleen should be performed if blood cultures are persistently positive for Candida spp. (S/L).
- Central venous catheter removal is strongly recommended (S/M).

CNS infections in Neonates
- For initial treatment, AmB deoxycholate, 1 mg/kg IV daily, is recommended (S/L).
- An alternative regimen is liposomal AmB, 5 mg/kg daily (S/L).
- The addition of flucytosine, 25 mg/kg 4 times daily, may be considered as salvage therapy in patients who have not had a clinical response to initial AmB therapy, but adverse effects are frequent (W/L).
- For step-down treatment after the patient has responded to initial treatment, fluconazole, 12 mg/kg daily, is recommended for isolates that are susceptible to fluconazole (S/L).
- Therapy should continue until all signs, symptoms, and CSF and radiological abnormalities, if present, have resolved (S/L).
- Infected CNS devices, including ventriculostomy drains and shunts, should be removed if at all possible (S/L).
Prophylaxis in the Neonatal ICU Setting
- In nurseries with high rates (>10%) of invasive candidiasis, intravenous or oral fluconazole prophylaxis, 3-6 mg/kg twice weekly for 6 weeks, in neonates with birth weights <1000 g is recommended (S/H).
- Oral nystatin, 100,000 units 3 times daily for 6 weeks, is an alternative to fluconazole in neonates with birth weights <1500 g in situations in which availability or resistance preclude the use of fluconazole (W/M).
- Oral bovine lactoferrin (100 mg/day) may be effective in neonates <1500 g but is not currently available in U.S. hospitals (W/M).
VIII. Intra-Abdominal Candidiasis
- Empirical antifungal therapy should be considered for patients with clinical evidence of intra-abdominal infection and significant risk factors for candidiasis, including recent abdominal surgery, anastomotic leaks, or necrotizing pancreatitis (S/M).
- Treatment of intra-abdominal candidiasis should include source control, with appropriate drainage and/or debridement (S/M).
- The choice of antifungal therapy is the same as for the treatment of candidemia or empirical therapy for non-neutropenic patients in the ICU (See Sections I and V) (S/M).
- The duration of therapy should be determined by adequacy of source control and clinical response (S/L).
IX. Candida Species in the Respiratory Tract
- Growth of Candida from respiratory secretions usually indicates colonization and rarely requires treatment with antifungal therapy (S/M).
X. Candida Intravascular Infections, Including Endocarditis and Infections of Implantable Cardiac Devices
Candida Endocarditis
- For native valve endocarditis, lipid formulation AmB, 3-5 mg/kg daily, with or without flucytosine, 25 mg/kg 4 times daily, OR high-dose echinocandin (caspofungin, 150 mg daily, micafungin, 150 mg daily, or anidulafungin, 200 mg daily) is recommended for initial therapy (S/L).

XII. Candida Endophthalmitis
General Approach to Candida Endophthalmitis
- All patients with candidemia should have a dilated retinal examination, preferably performed by an ophthalmologist, within the first week of therapy in non-neutropenic patients to establish if endophthalmitis is present (S/L). For neutropenic patients it is recommended to delay the examination until neutrophil recovery (S/L).
- The extent of ocular infection (chorioretinitis with or without macular involvement and with or without vitritis) should be determined by an ophthalmologist (S/L).
