Liposomal AmB (AmBisome) has been found to attain higher levels in the brain than amphotericin B lipid complex (ABLC) or AmB deoxycholate in a rabbit model of Candida meningoencephalitis [44]. What Is the Treatment for Candida Suppurative Thrombophlebitis? What Is the Treatment for Candida Endocarditis? Cases are fairly evenly divided between C. albicans and non-albicans Candida species [339]. Data are accruing on the use of skin decolonization with antiseptic agents in the ICU to decrease bloodstream infections, including those caused by Candida species [271274]. In a study of hepatosplenic candidiasis, at least one test was positive before radiographic changes in 86% of patients [142]. With the availability of other agents that achieve adequate concentrations in the vitreous, there is little reason to recommend the use of echinocandins for Candida endophthalmitis. Symptomatic infections caused by C. glabrata, C. dubliniensis, and C. krusei alone have been described [532534]. Information was requested regarding employment, consultancies, stock ownership, honoraria, research funding, expert testimony, and membership on company advisory committees. In many instances, clinical breakpoints have decreased from those used previously. An infection of the retina and inner parts of the eye can cause blindness. Higher-than-usual doses of echinocandins should be used, similar to therapy for endocarditis. If warranted, the entire panel or a subset thereof will be convened to discuss potential changes. A therapeutic trial with fluconazole for patients with presumed esophageal candidiasis is a cost-effective alternative to endoscopic examination. CNS Candida infections can occur as a manifestation of disseminated candidiasis, as a complication of a neurosurgical procedure, especially when an intracranial device is inserted, or rarely as an isolated chronic infection [453462]. Antifungal therapy of several months' duration, similar to that needed for osteomyelitis at other sites, is appropriate. Voriconazole is recommended as step-down oral therapy for selected cases of candidemia due to, All nonneutropenic patients with candidemia should have a dilated ophthalmological examination, preferably performed by an ophthalmologist, within the first week after diagnosis, Follow-up blood cultures should be performed every day or every other day to establish the time point at which candidemia has been cleared, Recommended duration of therapy for candidemia without obvious metastatic complications is for 2 weeks after documented clearance of, Central venous catheters (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, Lipid formulation AmB, 35 mg/kg daily, is an effective but less attractive alternative because of the potential for toxicity, 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, 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, Voriconazole, 400 mg (6 mg/kg) twice daily for 2 doses, then 200300 mg (34 mg/kg) twice daily, can be used in situations in which additional mold coverage is desired, Recommended minimum duration of therapy for candidemia without metastatic complications is 2 weeks after documented clearance of, Ophthalmological findings of choroidal and vitreal infection are minimal until recovery from neutropenia; therefore, dilated funduscopic examinations should be performed within the first week after recovery from neutropenia, In the neutropenic patient, sources of candidiasis other than a CVC (eg, gastrointestinal tract) predominate. Infection localized to the kidney, as occurs with hematogenous spread, probably can be treated with echinocandins because tissue concentrations are adequate even though these agents do not achieve adequate urine concentrations [499]. Premature discontinuation of antifungal therapy can lead to relapse, 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, For patients who have debilitating persistent fevers, short-term (12 weeks) treatment with nonsteroidal anti-inflammatory drugs or corticosteroids can be considered, Empiric 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 nonsterile sites, Preferred empiric therapy for suspected candidiasis in nonneutropenic patients in the intensive care unit (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), 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, Lipid formulation AmB, 35 mg/kg daily, is an alternative if there is intolerance to other antifungal agents, Recommended duration of empiric therapy for suspected invasive candidiasis in those patients who improve is 2 weeks, the same as for treatment of documented candidemia, For patients who have no clinical response to empiric antifungal therapy at 45 days and who do not have subsequent evidence of invasive candidiasis after the start of empiric therapy or have a negative non-culture-based diagnostic assay with a high negative predictive value, consideration should be given to stopping antifungal therapy, 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, 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), Daily bathing of ICU patients with chlorhexidine, which has been shown to decrease the incidence of bloodstream infections including candidemia, could be considered, AmB deoxycholate, 1 mg/kg daily, is recommended for neonates with disseminated candidiasis, Fluconazole, 12 mg/kg intravenous or oral daily, is a reasonable alternative in patients who have not been on fluconazole prophylaxis, Lipid formulation AmB, 35 mg/kg daily, is an alternative, but should be used with caution, particularly in the presence of urinary tract involvement, 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, A lumbar puncture and a dilated retinal examination are recommended in neonates with cultures positive for, Computed tomographic or ultrasound imaging of the genitourinary tract, liver, and spleen should be performed if blood cultures are persistently positive for, The recommended duration of therapy for candidemia without obvious metastatic complications is for 2 weeks after documented clearance of, For initial treatment, AmB deoxycholate, 1 mg/kg intravenous daily, is recommended, An alternative regimen is liposomal AmB, 5 mg/kg daily, 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, 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, Therapy should continue until all signs, symptoms, and cerebrospinal fluid (CSF) and radiological abnormalities, if present, have resolved, Infected central nervous system (CNS) devices, including ventriculostomy drains and shunts, should be removed if at all possible, In nurseries with high rates (>10%) of invasive candidiasis, intravenous or oral fluconazole prophylaxis, 36 mg/kg twice weekly for 6 weeks, in neonates with birth weights <1000 g is recommended, 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, Oral bovine lactoferrin (100 mg/day) may be effective in neonates <1500 g but is not currently available in US hospitals, Empiric 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, Treatment of intra-abdominal candidiasis should include source control, with appropriate drainage and/or debridement, The choice of antifungal therapy is the same as for the treatment of candidemia or empiric therapy for nonneutropenic patients in the ICU (See sections I and V), The duration of therapy should be determined by adequacy of source control and clinical response, For native valve endocarditis, lipid formulation AmB, 35 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, Step-down therapy to fluconazole, 400800 mg (612 mg/kg) daily, is recommended for patients who have susceptible, Oral voriconazole, 200300 mg (34 mg/kg) twice daily, or posaconazole tablets, 300 mg daily, can be used as step-down therapy for isolates that are susceptible to those agents but not susceptible to fluconazole, Valve replacement is recommended; treatment should continue for at least 6 weeks after surgery and for a longer duration in patients with perivalvular abscesses and other complications, For patients who cannot undergo valve replacement, long-term suppression with fluconazole, 400800 mg (612 mg/kg) daily, if the isolate is susceptible, is recommended, For prosthetic valve endocarditis, the same antifungal regimens suggested for native valve endocarditis are recommended (strong recommendation; low-quality evidence). Brain and central nervous system. What Is the Treatment for Esophageal Candidiasis? The greatest clinical experience for treatment of Candida endophthalmitis has been with intravenous AmB deoxycholate, only because it has been available for the longest time. What Is the Treatment for Candida Chorioretinitis With Vitritis? 12/16/2015, Clinical Infectious Diseases, Volume 62, Issue 4, 15 February 2016, Pages e1e50, https://doi.org/10.1093/cid/civ933Published: 16 December 2015, Peter G. Pappas, Carol A. Kauffman, David R. Andes, Cornelius J. Clancy, Kieren A. Marr, Luis Ostrosky-Zeichner, Annette C. Reboli, Mindy G. Schuster, Jose A. Vazquez, Thomas J. Walsh, Theoklis E. Zaoutis, Jack D. Sobel. Echinocandins appear to penetrate brain tissue, but not the CSF, and achieve concentrations in brain shown to be effective in animal models when dosages higher than those recommended for humans have been used [298, 299]. What is the treatment for oropharyngeal candidiasis? Candida bloodstream infections are associated with increased ICU and hospital stay [129, 235]. Concerns have been expressed about the reliability of antibody detection in immunosuppressed hosts, but assays have performed well in patients with neutropenia and cell-mediated immune defects (including hematopoietic cell and solid organ transplant recipients) [138, 139]. There are experimental animal data noting that anidulafungin and micafungin can successfully treat C. albicans meningitis, but the doses required in humans are much higher than currently recommended for candidemia [296, 299]. For the final version of these guidelines, the panel as a group reviewed all individual sections. Panel members were provided IDSA's conflicts of interest disclosure statement and were asked to identify ties to companies developing products that may be affected by promulgation of the guideline. Empiric therapy based solely on colonization with Candida species appears inadequate [16, 239]. This recommendation is based on limited data from prospective randomized trials and has been associated with few complications and relapses [209, 210]. Further confirmation of the efficacy and safety of oral bovine lactoferrin for the prevention of invasive candidiasis is needed, especially in infants <750 g, because there were only a few neonates in this category in this trial. Endocarditis should be suspected when blood cultures are persistently positive, when a patient with candidemia has persistent fever despite appropriate treatment, or when a new heart murmur, heart failure, or embolic phenomena occur in the setting of candidemia [338]. IX. This assessment of disclosed relationships for possible COI will be based on the relative weight of the nancial relationship (ie, monetary amount) and the relevance of the relationship (ie, the degree to which an association might reasonably be interpreted by an independent observer as related to the topic or recommendation of consideration). Small studies basing preemptive therapy on -D-glucan testing suggest that the high negative predictive value of this test could be useful in excluding invasive candidiasis in the ICU setting [151, 248, 250252]. Flucytosine demonstrates broad antifungal activity against most Candida species, with the exception of C. krusei. Fungal keratitis is an important eye infection, especially in outdoor workers. Treatment for Invasive Candidiasis How is invasive candidiasis treated? However, there remains a paucity of data on nystatin prophylaxis in infants <750 grams (the group at highest risk), and nystatin may not always be able to be administered when there is an ileus, gastrointestinal disease, feeding intolerance, or hemodynamic instability. In other settings, such as perforated appendicitis, invasive candidiasis appears to be a rare complication [316, 319]. What Is the Treatment for Candida Infection of Implantable Cardiac Devices? Flucytosine demonstrates good activity against many Candida species, with the exception of C. krusei, and is excreted as active drug in the urine [94]. Fluconazole may be considered in hemodynamically stable patients who are colonized with azole-susceptible Candida species or who have no prior exposure to azoles. Candida species are a common cause of fungal endophthalmitis. Candida albicans is the usual pathogen, but other Candida species can also cause this infection. A. V. has served as a consultant for Astellas, Forest, served on promotional speakers' bureau for Astellas, Pfizer, Forest, and Astra Zeneca, and has received research grants from Astellas, Pfizer, Merck, MSG, T2 Biosystems, and NIH/National Institute of Dental and Craniofacial Research. Long-term suppressive therapy with fluconazole has been shown to be effective in the prevention of oropharyngeal candidiasis [53, 542, 543]. There are no data guiding the appropriate duration of empiric antifungal therapy among patients who have a clinical response to therapy, but it is logical that it should not differ from the treatment of documented candidemia. What Is the Treatment for Asymptomatic Candiduria? Most experience with AmB is with the deoxycholate preparation. Candidemia is the most common manifestation of invasive candidiasis. Thus, the controversy continues, with some groups arguing for a strictly individualized approach to each patient [190] and others for an approach that removes CVCs in all nonneutropenic candidemic patients in whom it is safe and feasible to do so [19]. The specificity of -D-glucan can be improved by requiring consecutive positive results rather than a single result, but false positivity remains a significant limitation if the above-listed factors are common in the population tested. Neither the clinical picture nor the findings on radiographic imaging are specific for Candida infection. Each of these agents has been studied for the treatment of esophageal candidiasis [24, 87, 88] and invasive candidiasis [2534], and each has demonstrated efficacy in these situations. A recent multicenter point-prevalence survey identified Candida species as the most commonly isolated healthcare-associated bloodstream pathogen [4]. The current recommendation for micafungin for invasive candidiasis is 2 mg/kg/day, with the option to increase to 4 mg/kg/day in children <40 kg. Voriconazole is contraindicated during pregnancy because of fetal abnormalities observed in animals. An analysis of 842 patients enrolled in 2 phase 3 treatment trials failed to demonstrate significant clinical benefits of catheter removal in multivariable analyses that adjusted for other measures of prognostic significance [190]. IV. Not surprisingly, there were methodological differences among the studies, and there was variation among the study populations. The panel also greatly appreciates the work of Charles B. Wessels and Michele Klein Fedyshin of the Health Sciences Library System of the University of Pittsburgh for the development and execution of the systematic literature searches for this guideline. 1. What Is the Treatment for Symptomatic Ascending Candida Pyelonephritis? Common infections include vaginal yeast infection, diaper rash and thrush. Prompt and appropriate antifungal therapy is often delayed because of the relative insensitivity of blood cultures, the time needed for blood cultures to yield growth, the possibility of negative blood cultures with invasive abdominal candidiasis, and the lack of specific clinical signs and symptoms. Central venous catheters and other intravascular devices are important risk factors in the development and persistence of candidemia in nonneutropenic patients [5, 79, 184]. There are a few case reports and a single retrospective review of Candida infections of pacemakers and cardiac defibrillators [369374]. What is the treatment for central nervous system candidiasis? However, the role of corticosteroids in this disease is still not clear. Serum and (presumably) intraocular concentrations of voriconazole are quite variable, and serum trough levels should be routinely monitored to achieve concentrations between 2 g/mL and 5 g/mL to enhance efficacy and avoid toxicity [118]. Dosing in children is a loading dose of 70 mg/m2, followed by 50 mg/m2/day. A recent study comparing caspofungin to placebo among ICU patients with signs of infection, Candida colonization, and clinical risk factors for invasive candidiasis was stopped prematurely due to poor patient accrual, confirming the difficulty in conducting these trials [249]. Liver. The impact of the pharmacokinetics and differences in toxicity of lipid formulations of AmB have not been formally examined in clinical trials. Only a few reports note experience with voriconazole or posaconazole for this condition, but echinocandins are increasingly used to treat this infection [219, 223, 228231]. In both studies, Candida urinary tract infections, as well as invasive candidiasis and candidemia, were included as endpoints. In addition to identifying cases missed by blood cultures, the -D-glucan assay was positive a median of 5 and 6 days prior to positive intra-abdominal cultures and institution of antifungal therapy, respectively. With treatment, scalp yeast infections . Similarly, the colony count in the urine, especially when a catheter is present, cannot be used to define infection [488, 489]. For example, pyuria in a patient with an indwelling bladder catheter cannot differentiate Candida infection from colonization. For instance, the use of amphotericin B (AmB) plus fluconazole is as least as effective as higher-dose (800 mg daily) fluconazole given alone for patients with candidemia [22], but there is little role for this combination in current practice, especially as echinocandins are such a safe and effective alternative. To fully realize the benefits of combining culture and nonculture tests, however, clinicians must carefully consider the types of invasive candidiasis, understand the strengths and limitations of each assay, and interpret test results in the context of the clinical setting. In meta-analyses of -D-glucan studies, the pooled sensitivity and specificity for diagnosing invasive candidiasis were 75%80% and 80%, respectively [144146]. Oral voriconazole does not require dosage adjustment for renal insufficiency, but it is the only triazole that requires dosage reduction for patients with mild to moderate hepatic impairment [71]. Ocular candidiasis is a major complication of candidemia. For example, the prior Candida clinical breakpoint for susceptibility to fluconazole was 8 mg/L. Oct. 28, 2022 Fungal keratitis is an infection of the cornea. However, antifungal therapy must be continued during the period of immunosuppression to prevent relapse of infection [219, 223, 228231]. What is the treatment for candidemia in nonneutropenic patients? Blood cultures are limited by slow turnaround times (median time to positivity of 23 days, ranging from 1 to 7 days), and the fact that they may become positive relatively late in the disease course [130, 136]. A number of issues complicate the interpretation of these data, including uncertainties about the best cutoff value for a positive result, number of positive tests required to establish a diagnosis, and optimal timing and frequency of testing among at-risk patients. The development of reliable nonculture assays is critical to providing the opportunity for earlier intervention and more targeted antifungal therapy among large numbers of patients in whom traditional blood cultures are insensitive or provide untimely results [20]. Several reports have documented a high rate of candidemia when patients undergo urinary tract instrumentation [485, 486], which has led to recommendations to treat with antifungal agents periprocedure. Treatment should begin with induction therapy with a topical agent or oral fluconazole for 1014 days, followed by a maintenance azole regimen for at least 6 months [523525]. For ICUs that show very high rates of invasive candidiasis, in excess of the expected rates of <5% of patients, antifungal prophylaxis may be warranted in selected patients who are at highest risk [260]. Caspofungin and micafungin are approved by the US Food and Drug Administration (FDA) for use in children. In the first section, the panel summarizes background information relevant to the topic. Some reports have found surgical therapy important for Candida vertebral osteomyelitis [387], but others have not found that to be the case [388]. If not treated effectively, fungal infections can threaten vision. Flucytosine is usually given in combination with another antifungal agent due to a high rate of emergence of resistance during monotherapy [93]. Common polymorphisms in the gene encoding the primary metabolic enzyme for voriconazole result in wide variability of serum levels [72]. Response to antifungal therapy may be delayed when there is extensive skin or nail involvement.
