Abstract
OBJECTIVE To provide updates on the epidemiology and recommendations for management of candidemia in patients with critical illness. DATA SOURCES A literature search using the PubMed database (inception to March 2023) was conducted using the search terms "invasive candidiasis," "candidemia," "critically ill," "azoles," "echinocandin," "antifungal agents," "rapid diagnostics," "antifungal susceptibility testing," "therapeutic drug monitoring," "antifungal dosing," "persistent candidemia," and "Candida biofilm." STUDY SELECTION/DATA EXTRACTION Clinical data were limited to those published in the English language. Ongoing trials were identified through ClinicalTrials.gov. DATA SYNTHESIS A total of 109 articles were reviewed including 25 pharmacokinetic/pharmacodynamic studies and 30 studies including patient data, 13 of which were randomized controlled clinical trials. The remaining 54 articles included fungal surveillance data, in vitro studies, review articles, and survey data. The current 2016 Infectious Diseases Society of America (IDSA) Clinical Practice Guideline for the Management of Candidiasis provides recommendations for selecting empiric and definitive antifungal therapies for candidemia, but data are limited regarding optimized dosing strategies in critically ill patients with dynamic pharmacokinetic changes or persistent candidemia complicated. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE Outcomes due to candidemia remain poor despite improved diagnostic platforms, antifungal susceptibility testing, and antifungal therapy selection for candidemia in critically ill patients. Earlier detection and identification of the species causing candidemia combined with recognition of patient-specific factors leading to dosing discrepancies are crucial to improving outcomes in critically ill patients with candidemia. CONCLUSIONS Treatment of candidemia in critically ill patients must account for the incidence of non-albicans Candida species and trends in antifungal resistance as well as overcome the complex pathophysiologic changes to avoid suboptimal antifungal exposure.

Comparative efficacy and safety of systemic antifungal agents for candidemia: a systematic review with network meta-analysis and multicriteria acceptability analyses. Int J Antimicrob Agents 2022; 60:106614. [PMID: 35691603 DOI: 10.1016/j.ijantimicag.2022.106614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 05/19/2022] [Accepted: 05/30/2022] [Indexed: 11/05/2022]
Abstract
AIM Invasive candidiasis is the most common fungal infection in patients attending health services and is associated with high mortality rates and prolonged hospital stay. The aim of this review was to evaluate and compare efficacy and safety of antifungal agents for the treatment of candidemia. METHODS A systematic review with network meta-analysis (NMA), surface under the cumulative ranking analysis (SUCRA) and stochastic multicriteria acceptability analyses (SMAA) was performed (PROSPERO-CRD42020149264). Searches were conducted in PubMed and Scopus (Nov-2021). Randomised controlled trials evaluating the effect of oral antifungals (any dose or regimen) on mycological cure, discontinuation rates and adverse events were included. RESULTS Overall, 13 trials (n=3632) were analysed. There were no significant differences between therapies for the efficacy outcomes; however, caspofungin (50-150 mg), rezafungin (200-400 mg) and micafungin (100-150 mg) had higher rates of clinical and mycological responses (SUCRA overall response >60%) and were considered the most promising therapies. Fluconazole (400 mg) rated worst for overall response (17%). Rezafungin (200-400 mg) and micafungin (100 mg) were associated with lower discontinuation rates (<40%). Conventional amphotericin B (0.6-0.7 mg/kg) was more likely to be discontinued (odds ratio [OR] 0.08; 95% credibility interval [CrI] 0.00-0.95 vs. caspofungin 150 mg) and may impair liver function (87%). CONCLUSION Echinocandins are recommended as first-line treatments for invasive candidiasis following a priority order of caspofungin then micafungin. Rezafungin, an echinocandin under development, represents a potential option that should be further investigated. Azoles and liposomal amphotericin B can be used as second-line treatments in cases of fungal resistance or hypersensitivity.

Mycoses 2021; 65:211-221. [PMID: 34847247 DOI: 10.1111/myc.13406] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 11/26/2021] [Accepted: 11/27/2021] [Indexed: 11/26/2022]
Abstract
OBJECTIVES The relevance of candidemia has increased over the last decades due to higher incidence rates in an ageing society. Studies on amphotericin B and fluconazole have shown high attributable mortality rates of 38% and 49% in the United States. Incidence rates and locational factors might have an impact on the mortality rates at the University Hospital of Cologne (UHC), Germany. METHODS We performed a matched case-control study including 57 patients with candidemia, hospitalised at the UHC between 1 July 1997 and 30 June 2001. Controls were matched by age, sex, admission date, treatment on intensive care unit (ICU), number of days at risk, underlying diseases, surgical procedures and the Charlson Comorbidity Index. RESULTS The incidence of candidemia was 3.5 per 10 000 admissions. For cases and controls, we observed in-hospital-mortality rates of 33.3% and 11.8%, and a 30-day mortality of 23.5% and 7.8% respectively. The attributable mortality rate to candidemia was 21.5%, and at 30 days, it was 15.7%. Underlying conditions were more frequent in cases than in controls, especially central venous catheter (80% vs 33%, P < .001), chronic cardiovascular disease (39.2% vs 25.5%, P = .138), treatment on ICU (31.4% vs 13.7%, P = .033) and chronic liver disease (21.6% vs 0%, P < .001). CONCLUSIONS The attributable mortality of candidemia at the UHC between 1997 and 2001 was lower compared to studies performed in the United States with a similar design. Contributing factors might be lower incidence rates and less comorbidities in our study.

Abstract
BACKGROUND + OBJECTIVES: The echinocandins, amphotericin B preparations, voriconazole and fluconazole are approved for the treatment of invasive candidiasis, though it remains unclear which agent is most effective. In order to answer this question, we performed a systematic review and network meta-analysis of the randomised controlled trials (RCTs) which evaluated these agents in comparison. METHODS Four electronic databases were searched from database inception to 8 October 2020. RCTs comparing triazoles, echinocandins or amphotericin B for the treatment of invasive candidiasis or candidemia were included. Random effect Bayesian network meta-analysis methods were used to compare treatment outcomes. RESULTS Thirteen RCTs met inclusion criteria. Of the 3528 patients included from these trials, 1531 were randomised to receive an echinocandin, 944 to amphotericin B and 1053 to a triazole. For all forms of invasive candidiasis, echinocandins were associated with the highest rate of treatment success when compared to amphotericin B (OR 1.41, 95% CI 1.04-1.92) and the triazoles (OR 1.82, 95% CI 1.35-2.51). Rank probability analysis favoured echinocandins as the most effective choice 98% of the time. Overall survival did not significantly differ between groups. CONCLUSIONS Among patients with invasive candidiasis, echinocandins had the best clinical outcomes and should remain the first-line agents in the treatment of invasive candidiasis.

Azoles versus conventional amphotericin B for the treatment of candidemia: A meta-analysis of randomized controlled trials. J Infect Chemother 2020; 26:1232-1236. [PMID: 32828679 DOI: 10.1016/j.jiac.2020.07.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 07/25/2020] [Accepted: 07/31/2020] [Indexed: 10/23/2022]
Abstract
Because exclusive use of echinocandins can induce the drug-resistant strains, appropriate use of azoles and polyenes is still necessary in the treatment of candidemia. In this study, we conducted a meta-analysis of randomized controlled trials regarding the efficacy and safety of azole and polyene antifungals in the treatment of candidemia. MEDLINE and the Cochrane Register of Controlled Trials were used as reference databases, and papers published up to June 10, 2019 were searched. The search results were carefully scrutinized, duplicate references were removed, and the study was ultimately carried out using three reports. Among azole antifungals, fluconazole and voriconazole were extracted, however; only conventional amphotericin B (AMPH-B) was extracted among polyene antifungals. Treatment successes with the use of azoles and AMPH-B were compared, and findings showed that AMPH-B was significantly superior (RR = 0.90, 95% CI 0.82-1.00, p = 0.04). However, there was no significant difference in mortality (RR = 0.87, 95% CI 0.72-1.07, p = 0.19). Analysis of adverse events showed that renal disorders were significantly less common with azoles than with AMPH-B (RR = 0.26, 95% CI 0.10-0.68, p = 0.006). In conclusion, AMPH-B were superior to azoles in terms of efficacy, but had a risk of causing renal disorders.

Abstract
These updated guidelines from the American Society of Transplantation Infectious Diseases Community of Practice provide recommendations for the diagnosis and management of Candida infections in solid organ transplant recipients. Candida infections manifest primarily as candidemia and invasive candidiasis and cause considerable morbidity and mortality. Early diagnosis and initiation of treatment are necessary to reduce mortality. For both candidemia and invasive candidiasis, an echinocandin is recommended for initial therapy. However, early transition to oral therapy is encouraged when patients are stable and the organism is susceptible. Candida prophylaxis should be targeted for high-risk patients in liver, small bowel, and pancreas transplant recipients. Future research should address which patient groups may benefit most from preventative antifungal therapy strategies.

Abstract
To investigate the causes and the clinical significance of persistent candidemia (PC) in adults diagnosed in a tertiary hospital with an active antifungal stewardship program. Retrospective cohort including all adults with candidemia from 2010 to 2018. PC was defined as any positive follow-up blood culture (BC) obtained ≥ 5 days from the first BCs yielding the same Candida species. PC was detected in 35/255 (13.7%) patients. There were no differences regarding antifungal adequacy in PC vs. non-PC (94.3% vs. 82.3%, p = 0.084) and primary source control (63.3% vs. 76.4%, p = 0.172) at the time of the follow-up BCs. The average time until source control (2 [0-37] vs. 2 days [0-44], p = 0.311) or adequate antifungal treatment (2 [0-26] vs. 2 days [- 2-10], p = 0.748) was similar. Patients with PC had more non-ocular complications (31.4% vs. 10.5%, p = 0.002). No impact on 30-day mortality was observed (31.4% vs. 22.3%, p = 0.238). The only independent factor associated with PC was to have a previously undetected site of infection [OR 4.28, 95%CI (1.77-10.34), p = 0.001]. Persistent candidemia was not associated with inadequate or delayed therapeutic management, nor higher 30-day mortality rates. Timely screening and control of unexpected infection sources are encouraged to shorten hospitalization and improve patient care.

Abstract
Invasive candidiasis occurs frequently in hospitalized patients, and is associated with high mortality rates due to delays in recognition and initiation of appropriate antifungals. Management of invasive candidiasis must take into account multiple host, pathogen, and drug-related factors, including the site of infection, host immune status, severity of sepsis, resistance and tolerance to antifungal agents, biofilm formation, and pharmacokinetic/pharmacodynamic considerations. Recent treatment directives have been shaped by the widespread introduction of echinocandins, highly potent and safe antifungals, into clinical use, as well as important changes in drug susceptibility patterns and the emergence of known and novel drug-resistant Candida species. Advances in molecular diagnostics have the potential to guide early targeted treatment of high-risk patients.

Abstract
AIMS Guidelines on treating invasive candidiasis recommend initial treatment with a broad-spectrum echinocandin (e.g. micafungin), then switching to fluconazole if isolates prove sensitive (de-escalation strategy). This study aimed to evaluate the cost-effectiveness of de-escalation from micafungin vs escalation from fluconazole from a Chinese public payers perspective. MATERIALS AND METHODS Cost-effectiveness was estimated using a decision analytic model, in which patients begin treatment with fluconazole 400 mg/day (escalation) or micafungin 100 mg/day (de-escalation). From Day 3, when susceptibility results are available, patients are treated with either fluconazole (if isolates are fluconazole-sensitive/dose-dependent) or micafungin (if isolates are resistant). The total duration of (appropriate) treatment is 14 days. Model inputs are early (Day 3) and end-of-treatment mortality rates, treatment success rates, and health resource utilization. Model outputs are costs of health resource utilization over 42 days, incremental cost per life-year, and incremental cost per quality-adjusted life-year (QALY) over a lifetime horizon. RESULTS In the base-case analysis, the de-escalation strategy was associated with longer survival and higher treatment success rates compared with escalation, at a lower overall cost (-¥1,154; -175 United States Dollars). Life-years and QALYs were also better with de-escalation. Thus, this strategy dominated the escalation strategy for all outcomes. In a probabilistic sensitivity analysis, 99% of 10,000 simulations were below the very cost-effective threshold (1 × gross domestic product). LIMITATIONS The main limitation of the study was the lack of real-world input data for clinical outcomes on treatment with micafungin in China; data from other countries were included in the model. CONCLUSION A de-escalation strategy is cost-saving from the Chinese public health payer perspective compared with escalation. It improves outcomes and reduces costs to the health system by reducing hospitalization, due to an increase in the proportion of patients receiving appropriate treatment.

Abstract
The purpose of this study was to determine whether fungicidal versus fungistatic pharmacotherapy of invasive candidiasis/candidemia yields superior outcomes. Data sources included MEDLINE (1966-June 2017), EMBASE (1980-June 2017), PubMed (1966-June 2017), Global Health-Ovid (inception to June 2017), LILACS Virtual Health Library (inception to June 2017) and the Cochrane Central Register of Controlled Trials (to 2nd quarter 2017). The ClinicalTrial.gov database, the SCOPUS database, SIGLE (System for Information on Grey Literature) and Google Scholar were also utilised to search for relevant studies. Randomised studies of any pharmacotherapy of invasive candidiasis including candidemia using a fungicidal (amphotericin B or echinocandin compound) versus a fungistatic (triazole) compound in adolescent or adult non-neutropenic patients. Eight studies met the inclusion criteria. Pooled odds ratios demonstrated an advantage of fungicidal therapy with respect to early therapeutic success (OR 1.61, 95% CI 1.27-2.03, p < 0.0001, I2 = 0%) and persistence or recurrence of infection (OR 0.51, 95% CI 0.35-0.74, p = 0.0005, I2 = 0%) but no advantage for late survival (OR 0.97, 95% CI 0.77-1.21, p = 0.77, I2 = 0%). Fungicidal therapy of invasive candidiasis and candidemia is associated with a higher probability of early therapeutic success and decreased probability of persistent or recurrent infection. However, there is no improvement in survival.

Abstract
Background The incidence of azole-resistant Candida infections is increasing. Consequently, guidelines for treating systemic Candida infection (SCI) recommend a “de-escalation” strategy: initial broad-spectrum antifungal agents (e.g., echinocandins), followed by switching to fluconazole if isolates are fluconazole sensitive, rather than “escalation” with initial fluconazole treatment and then switching to echinocandins if isolates are fluconazole resistant. However, fluconazole may continue to be used as first-line treatment in view of its low acquisition costs. The aim of this study was, therefore, to evaluate the budget impact of the de-escalation strategy using micafungin compared with the escalation strategy in France and Germany. Methods A budget impact model was used to compare de-escalation to escalation strategies. As well as survival, clinical success (resolution/reduction of symptoms and radiographic abnormalities associated with fungal infection), was considered, as was mycological success (eradication of Candida from the bloodstream). Health economic outcomes included cost per health state according to clinical success and mycological success, and budget impact. A 42-day time horizon was used. Results For all patients with SCI, the budget impact of using de-escalation rather than escalation was greater, but improved rates of survival, clinical success and mycological success were apparent with de-escalation. In patients with fluconazole-resistant isolates, clinical success rates and survival were improved by ~72% with de-escalation versus escalation, producing cost savings of €6,374 and €356 per patient in France and Germany, respectively; improvements of ~72% in mycological success rates with de-escalation versus escalation did not translate into cost savings. Conclusion Modeling provides evidence that when treating SCI in individuals at risk of azole-resistant infections, de-escalation from micafungin has potential cost savings associated with improved clinical success rates.

Abstract
The European Conference on Infections in Leukemia (ECIL) provides recommendations for diagnostic strategies and prophylactic, pre-emptive or targeted therapy strategies for various types of infection in patients with hematologic malignancies or hematopoietic stem cell transplantation recipients. Meetings are held every two years since 2005 and evidence-based recommendations are elaborated after evaluation of the literature and discussion among specialists of nearly all European countries. In this manuscript, the ECIL group presents the 2015-update of the recommendations for the targeted treatment of invasive candidiasis, aspergillosis and mucormycosis. Current data now allow a very strong recommendation in favor of echinocandins for first-line therapy of candidemia irrespective of the underlying predisposing factors. Anidulafungin has been given the same grading as the other echinocandins for hemato-oncological patients. The beneficial role of catheter removal in candidemia is strengthened. Aspergillus guidelines now recommend the use of either voriconazole or isavuconazole for first-line treatment of invasive aspergillosis, while first-line combination antifungal therapy is not routinely recommended. As only few new data were published since the last ECIL guidelines, no major changes were made to mucormycosis recommendations.

Abstract
INTRODUCTION Invasive fungal diseases (IFDs) are a leading cause of morbidity and mortality among immunocompromised patients with bone marrow failure syndromes, hematological malignancies, hematopoietic stem cell transplantation (HSCT), those admitted in intensive care units (ICUs) and those with prolonged febrile neutropenia. IFDs occur in a setting of multiple morbidities and are associated with case fatality rates between 30 and 70%. Along with the development of classes and compounds, the last two decades have seen substantial improvements in the prevention and management of these infections and an overall increased use of antifungal agents. Areas covered: All antifungal agents, including amphotericin B formulations, echinocandins and the triazoles, may cause hepatic toxicity that ranges from mild and asymptomatic abnormalities in liver function tests to substantial liver injury and fulminant hepatic failure. Expert opinion: The present article reviews incidence and severity of hepatotoxicity associated with different classes and agents to provide a better understanding of this specific end organ toxicity and safer use of antifungal agents A thorough understanding of the distribution, metabolism, elimination and drug-drug interactions of antifungal agents used for management of IFDs in combination with safety data from clinical trials, pharmacokinetic and pharmacodynamic studies may guide the use of antifungal treatment in patients at high risk for the development of hepatic dysfunction and in those with underlying liver damage due to cytotoxic therapy.

Abstract
Recent epidemiologic studies reveal both an increasing incidence and an escalation in resistance of invasive fungal infections in intensive care units. Primary therapy fails in 70 % of cases, depending on the underlying pathogens and diseases. The purpose of this review is to raise awareness for the topic of antifungal therapy failure, describe the clinical conditions in which it occurs, and suggest a possible algorithm for handling the situation of suspected primary therapy failure.

Abstract
Invasive fungal infections have become an increasingly prevalent and disturbing problem in critically ill patients. The advent of broad-spectrum antibacterial therapy and immunosuppressant therapy, among other factors such as mechanical ventilation, places the intensive care patient at significant risk for infection with pathogenic fungi. Most patients who become infected with invasive fungi, especially Candida species, have been previously colonized with the offending organism, lending to the notion that colonization precedes infection inmany cases. Despite an ever-increasing array of antifungal therapy for these infections, mortality rates remain extremely high, especially when the bloodstream is the primary site of infection. In addition, a shift toward more resistant pathogens such asCandida glabrata, Candida krusei, and moldswill provide clinicianswith therapeutic challenges for many years. The wide variation in acquisition cost across antifungal agents adds an additional layer of complexity to clinical decision making. Newer antifungal agents, each with its own advantages and disadvantages, have become available in recent years. Placing each agent in its appropriate niche is a dilemma that has yet to be solved.

Abstract
A spiroindolinone, (1S,3R,3aR,6aS)-1-benzyl-6'-chloro-5-(4-fluorophenyl)-7'-methylspiro[1,2,3a,6a-tetrahydropyrrolo[3,4-c]pyrrole-3,3'-1H-indole]-2',4,6-trione, was previously reported to enhance the antifungal effect of fluconazole against Candida albicans. A diastereomer of this compound was synthesized, along with various analogues. Many of the compounds were shown to enhance the antifungal effect of fluconazole against C. albicans, some with exquisite potency. One spirocyclic piperazine derivative, which we have named synazo-1, was found to enhance the effect of fluconazole with an EC50 value of 300 pM against a susceptible strain of C. albicans and going as low as 2 nM against some resistant strains. Synazo-1 exhibits true synergy with fluconazole, with an FIC index below 0.5 in the strains tested. Synazo-1 exhibited low toxicity in mammalian cells relative to the concentrations required for antifungal synergy.

Abstract
Pathogenic yeast forms are commonly associated with invasive fungal disease in the immunocompromised host, including patients with haematological malignancies and patients of haemopoietic stem cell transplants. Yeasts include the Candida spp., Cryptococcus spp., Pneumocystis jirovecii and some lesser-known pathogens. Candida species remain the most common cause of invasive yeast infections (and the most common human pathogenic fungi). These guidelines present evidence-based recommendations for the antifungal management of established, invasive yeast infections in adult and paediatric patients in the haematology/oncology setting. Consideration is also given to the critically ill patient in intensive care units, including the neonatal intensive care unit. Evidence for 'pre-emptive' or 'diagnostic-driven antifungal therapy' is also discussed. For the purposes of this paper, invasive yeast diseases are categorised under the headings of invasive candidiasis, cryptococcosis and uncommon yeast infections. Specific recommendations for the management of Pneumocystis jirovecii are presented in an accompanying article (see consensus guidelines by Cooley et al. appearing elsewhere in this supplement).

Abstract
Small intestinal fungal overgrowth (SIFO) is characterized by the presence of excessive number of fungal organisms in the small intestine associated with gastrointestinal (GI) symptoms. Candidiasis is known to cause GI symptoms particularly in immunocompromised patients or those receiving steroids or antibiotics. However, only recently, there is emerging literature that an overgrowth of fungus in the small intestine of non-immunocompromised subjects may cause unexplained GI symptoms. Two recent studies showed that 26 % (24/94) and 25.3 % (38/150) of a series of patients with unexplained GI symptoms had SIFO. The most common symptoms observed in these patients were belching, bloating, indigestion, nausea, diarrhea, and gas. The underlying mechanism(s) that predisposes to SIFO is unclear but small intestinal dysmotility and use of proton pump inhibitors has been implicated. However, further studies are needed; both to confirm these observations and to examine the clinical relevance of fungal overgrowth, both in healthy subjects and in patients with otherwise unexplained GI symptoms. Importantly, whether eradication or its treatment leads to resolution of symptoms remains unclear; at present, a 2-3-week course of antifungal therapy is recommended and may be effective in improving symptoms, but evidence for eradication is lacking.

Abstract
Candidia spp. are responsible for contributing to the increasing global prevalence of fungal infections. Fluconazole (Diflucan((R)), Pfizer) is a triazole that has established an exceptional therapeutic record for candida infections including oropharyngeal and esophageal candidiasis, vulvovaginal candidiasis, candidemia and disseminated candidiasis. It is both an oral and parenteral fungistatic agent that inhibits ergosterol synthesis in yeasts. Extensive clinical studies have demonstrated fluconazole's remarkable efficacy, favorable pharmacokinetics and reassuring safety profile, all of which have contributed to its widespread use. Fluconazole became the first antifungal with worldwide sales exceeding billions of dollars, therefore providing an incentive for the pharmaceutical industry to develop new antifungals. This review will examine the contributions and limitations of fluconazole in the treatment of superficial and invasive candidiasis syndromes.

Abstract
INTRODUCTION Invasive candidiasis (IC) has primarily been studied in intensive care unit (ICU) patients, although, in reality, a vast majority of these infections occur outside of the ICU. The recent publication of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines also deal with the non-ICU population, but many uncertainties remain on the management of IC, particularly in non-critically ill patients. METHODS The Italian Society of Antimicrobial Therapy, Società Italiana di Terapia Antimicrobica (SITA), produced practical, hospital-wide recommendations on the management of Candida infection in non-immunocompromised patients in the hospital ward. RESULTS AND DISCUSSION Our focus is on patient stratification in terms of risk factors for IC and of clinical severity, emphasising a high index of suspicion to ensure early diagnosis, early treatment and de-escalation when a patient is clinically stable, in order to optimise resource allocation.

Abstract
BACKGROUND Systemic Candida infections (SCI) occur predominantly in intensive care unit patients and are a common cause of morbidity and mortality. Recently, changes in Candida epidemiology with an increasing prevalence of SCI caused by Candida non-albicans species have been reported. Resistance to fluconazole and azoles in general is not uncommon for non-albicans species. Despite guidelines recommending initial treatment with broad-spectrum antifungals such as echinocandins with subsequent switch to fluconazole if isolates are sensitive (de-escalation strategy), fluconazole is still the preferred first-line antifungal (escalation) in many clinical practice settings. After diagnosis of the pathogen, the initial therapy with fluconazole is switched to a broad-spectrum antifungal if a non-albicans is identified. METHODS The cost-effectiveness of initial treatment with micafungin (de-escalation) vs fluconazole (escalation) in patients with SCI was estimated using decision analysis based on clinical and microbiological data from pertinent studies. The model horizon was 42 days, and was extrapolated to cover a lifetime horizon. All costs were analyzed from the UK NHS perspective. Several assumptions were taken to address uncertainties; the limitations of these assumptions are discussed in the article. RESULTS In patients with fluconazole-resistant isolates, initial treatment with micafungin avoids 30% more deaths and successfully treats 23% more patients than initial treatment with fluconazole, with cost savings of £1621 per treated patient. In the overall SCI population, de-escalation results in 1.2% fewer deaths at a marginal cost of £740 per patient. Over a lifetime horizon, the incremental cost-effectiveness of de-escalation vs escalation was £15,522 per life-year and £25,673 per QALY. CONCLUSIONS De-escalation from micafungin may improve clinical outcomes and overall survival, particularly among patients with fluconazole-resistant Candida strains. De-escalation from initial treatment with micafungin is a cost-effective alternative to escalation from a UK NHS perspective, with a differential cost per QALY below the 'willingness-to-pay' threshold of £30,000.

Abstract
Primary treatment failure and mortality in non-neutropenic patients with candidemia is high according to clinical trial experience. Current guidelines are mainly useful only for first line treatment strategies.We describe treatment failure and persistent protracted Candida albicans candidemia without clinically evident ocular involvement nor catheter recolonization in a malnourished non-neutropenic surgical patient with peritonitis. Primary antifungal treatment failure with fluconazole and secondary treatment failure with caspofungin occurred in the absence of evident Candida seeding the eye, valvular endocardium, or the intravascular catheter. Switch to liposomal amphotericin B was followed by clinical and microbiological cure. In patients with multiple risk factors for the acquisition of candidemia and life-threatening clinical conditions, the possibility of primary/secondary failure of new potent antifungal regimens may be initially neglected. Additional multicenter controlled clinical data are needed to guide the timing and choice of secondary antifungal treatment regimens in non-neutropenic candidemia patients.

Abstract
BACKGROUND Candidemia is a common cause of nosocomial bloodstream infection. When selecting therapeutic treatments for candidemia, cost-effectiveness is an important consideration. The present study assessed the cost-effectiveness of voriconazole for the treatment of candidemia. METHODS A decision-analytical model was used for evaluating the cost-effectiveness of voriconazole compared with a regimen of conventional amphotericin B (CAB) followed by fluconazole (FLU) in the treatment of non-neutropenic patients diagnosed with candidemia in the Canadian setting, based on the Global Candidemia Study. The time frame of the model was 98 days (14 weeks). Model parameters were based primarily on clinical outcome, and resource use data collected from the clinical trial were used. Supplemental data were obtained from an independent panel of 12 Canadian experts for parameters not available from the clinical trial. Unit costs were collected from Canadian sources. The outcome variables selected in the study were the number of patients cured within 98 days, the number of patients surviving at 98 days and the number of patients avoiding toxicity. Incremental costs per outcome were calculated to compare the cost-effectiveness analyses (both probabilistic and one-way sensitivity analyses were performed). RESULTS The cost-effectiveness analysis demonstrated a difference of $1,121 in the total average cost of treatment with voriconazole ($70,489) versus CAB/FLU ($69,368). While the costs of voriconazole exceeded the costs of CAB/FLU, these costs were almost completely offset by lower hospitalization costs. While patients in both treatment arms experienced cure rates of 41%, both the percentage of patients surviving at day 98 (64.5% versus 58.2%) and the percentage of patients avoiding toxicity (64.5% versus 52.5%) were higher in the voriconazole arm. Accounting for differences in total costs and clinical outcomes, this analysis estimated an incremental cost per patient surviving at day 98 of $17,739, and an incremental cost per patient avoiding toxicity of $9,298. In the case of cost per patient cured, voriconazole had a higher cost ($1,121) than CAB/FLU. The results of the deterministic and probabilistic sensitivity analyses indicated that the model was robust. CONCLUSIONS Results of the decision-analytical model provided evidence to support the cost-effectiveness of voriconazole relative to a regimen of CAB/FLU in the treatment of non-neutropenic patients diagnosed with candidemia in the Canadian setting.

Efficacy of micafungin in invasive candidiasis caused by common Candida species with special emphasis on non-albicans Candida species. Mycoses 2013; 57:79-89.

Abstract
The incidence of invasive candidiasis caused by non-albicans Candida (NAC) spp. is increasing. The aim of this analysis was to evaluate the efficacy of micafungin, caspofungin and liposomal amphotericin B in patients with invasive candidiasis and candidaemia caused by different Candida spp. This post hoc analysis used data obtained from two randomised phase III trials was conducted to evaluate the efficacy and safety of micafungin vs. caspofungin and micafungin vs. liposomal amphotericin B. Treatment success, clinical response, mycological response and mortality were evaluated in patients infected with C. albicans and NAC spp. Treatment success rates in patients with either C. albicans or NAC infections were similar. Outcomes were similar for micafungin, caspofungin and liposomal amphotericin B. Candida albicans was the most prevalent pathogen recovered (41.0%), followed by C. tropicalis (17.9%), C. parapsilosis (14.4%), C. glabrata (10.4%), multiple Candida spp. (7.3%) and C. krusei (3.2%). Age, primary diagnosis (i.e. candidaemia or invasive candidiasis), previous corticosteroid therapy and Acute Physiology and Chronic Health Evaluation II score were identified as potential predictors of treatment success and mortality. Micafungin, caspofungin and liposomal amphotericin B exhibit favourable treatment response rates that are comparable for patients infected with different Candida spp.

Abstract
Invasive fungal infections, especially in the critical care setting, have become an excellent target for prophylactic, empiric, and pre-emptive therapy interventions due to their associated high morbidity, mortality rate, increased incidence, and healthcare costs. For these reasons, new studies and laboratory tests have been developed over the last few years in order to formulate an early therapeutic intervention strategy in an attempt to reduce the high mortality rate associated with these infections. In recent years, evidence-based studies have shown the roles that the new antifungal drugs play in the treatment of invasive mycosis in seriously ill and complex patients, although data from critically ill patients are more limited. New antifungal agents have been analyzed in different clinical situations in critical care units, and the increasing number of non-Candida albicans species suggest that the application of early echinocandin therapy in critically ill patients with invasive candidiasis is a good option. Voriconazole should be recommended for invasive aspergillosis as a first line option.

Abstract
INTRODUCTION Invasive candidiasis (IC), mainly candidemia, is a leading cause of morbidity and mortality among immunocompromised patients and those admitted to intensive care units. Despite the recognition of risk factors and advances in disease prevention, Candida-related hospitalizations and mortality continue to rise. For treatment, four classes of older and newer antifungal agents are currently available. Adjunctive immunotherapies and a monoclonal antibody against heat shock protein 90 (efungumab) are promising novel therapeutic approaches. AREAS COVERED In this article, approaches and therapeutic agents for candidemia and other forms of IC are reviewed. EXPERT OPINION The thorough understanding of the available antifungal agents in combination with the increasing knowledge of the mechanisms that underlie the pathogenesis of Candida infections and the development of newer approaches such as efungumab and immunotherapy with adjunctive cytokines may improve the prognosis of patients with life-threatening invasive Candida infections.

Abstract
Critically ill patients in the intensive care unit (ICU) are at increased risk of encountering bloodstream infections (BSIs) with Candida spp., associated with an elevated crude mortality rate. This supports the significance of early detection of infection and identification of the most effective management approach. A review of the various antifungal treatments and an evaluation of the diverse management approaches for invasive candidiasis in critically ill patients is necessary for guiding evidence-based decision-making. Different early detection schemes for invasive candidiasis are well documented in the literature. Other than the common use of blood cultures, new methods entail the use of risk prediction scores and biomarker tests. Regarding management strategies, different options are currently supported. These include prophylaxis, empirical therapy, pre-emptive therapy, and treatment of culture-documented infections. The choice of treatment is greatly dependent on several factors related to the patient and/or to the surrounding environment. Attention needs to be given to previous exposure to azoles, epidemiological data on dominant Candida spp. in local ICUs, severity of illness and associated morbidities. This paper summarises the most recent literature as well as the guidelines issued by the Infectious Diseases Society of America. The objective is to identify the best diagnosis and management approaches for serious Candida infections in critically ill patients. In addition, this article addresses an important aspect associated with managing candidaemia in critically ill patients pertaining to the decision for intravenous catheter removal.

Abstract
This part of the EFISG guidelines focuses on non-neutropenic adult patients. Only a few of the numerous recommendations can be summarized in the abstract. Prophylactic usage of fluconazole is supported in patients with recent abdominal surgery and recurrent gastrointestinal perforations or anastomotic leakages. Candida isolation from respiratory secretions alone should never prompt treatment. For the targeted initial treatment of candidaemia, echinocandins are strongly recommended while liposomal amphotericin B and voriconazole are supported with moderate, and fluconazole with marginal strength. Treatment duration for candidaemia should be a minimum of 14 days after the end of candidaemia, which can be determined by one blood culture per day until negativity. Switching to oral treatment after 10 days of intravenous therapy has been safe in stable patients with susceptible Candida species. In candidaemia, removal of indwelling catheters is strongly recommended. If catheters cannot be removed, lipid-based amphotericin B or echinocandins should be preferred over azoles. Transoesophageal echocardiography and fundoscopy should be performed to detect organ involvement. Native valve endocarditis requires surgery within a week, while in prosthetic valve endocarditis, earlier surgery may be beneficial. The antifungal regimen of choice is liposomal amphotericin B +/- flucytosine. In ocular candidiasis, liposomal amphotericin B +/- flucytosine is recommended when the susceptibility of the isolate is unknown, and in susceptible isolates, fluconazole and voriconazole are alternatives. Amphotericin B deoxycholate is not recommended for any indication due to severe side effects.

Abstract
Invasive fungal disease represents a major complication in hematological patients. Antifungal agents are frequently used in hematologic patients for different purposes. In neutropenic patients, antifungal agents may be used as prophylaxis, as empiric or preemptive therapy, or to treat an invasive fungal disease that has been diagnosed. The hematologist must be familiar with the epidemiology, diagnostic tools and strategies of antifungal use, as well as the pharmacologic proprieties of the different antifungal agents. In this paper the principal antifungal agents used in hematologic patients will be discussed as will the clinical scenarios where these agents have been used.

Abstract
Systemic fungal infections typically occur in individuals who are seriously ill with recognized risk factors such as those frequently found in transplant recipients. Unfortunately, they are often diagnosed late, when the efficacy of the available treatments is low, often less than 50%, and the cost in terms of lives lost, hospital length of stay, and total hospital costs is substantially increased. The application of antifungal therapies associated with reported efficacy rates greater than 50% are those used prophylactically. When used prophylactically, these infections are reduced in greater than 95% of the expected cases. The choice of a prophylactic agent should be based upon its ease of administration, lack of adverse effects, reduced likelihood of potential drug interactions, and its efficacy in patients with established risk factors and comorbid disease processes that include renal, hepatic, and chronic pulmonary disease. The indications for the use of currently available antifungal agents, their adverse effects, drug interactions, ease of dosing, and applicability in patients with preexisting disease states, and especially in liver transplant recipients, are presented in this paper.

Abstract
The high morbidity, mortality, and health care costs associated with invasive fungal infections, especially in the critical care setting and immunocompromised host, have made it an excellent target for prophylactic, empiric, and preemptive therapy interventions principally based on early identification of risk factors. Early diagnosis and treatment are associated with a better prognosis. In the last years there have been important developments in antifungal pharmacotherapy. An approach to the new diagnosis tools in the clinical mycology laboratory and an analysis of the use new antifungal agents and its application in different clinical situations has been made. Furthermore, an attempt of developing a state of the art in each clinical scenario (critically ill, hematological, and solid organ transplant patients) has been performed, trying to choose the best strategy for each clinical situation (prophylaxis, pre-emptive, empirical, or targeted therapy). The high mortality rates in these settings make mandatory the application of early de-escalation therapy in critically ill patients with fungal infection. In addition, the possibility of antifungal combination therapy might be considered in solid organ transplant and hematological patients.

Abstract
BACKGROUND CONTEXT Discitis or epidural abscess after discogram is a rare but known complication. It is more commonly bacterial; however, fungal discitis has been previously reported in immunocompromised patients. The management of fungal discitis in immunocompetent patients is rarely presented or addressed in the literature. PURPOSE To present a rare atypical fungal discitis after routine discogram with a typical presentation in an immunocompetent host, review diagnostic and management guidelines for discitis, and provide recommendations for management of atypical discitis in immunocompetent patients. STUDY DESIGN Case report and review of the literature. METHODS A 40-year-old woman presented with a 3-week history of progressively worsening low back pain after a lumbar discogram. Magnetic resonance imaging revealed L3-L4 discitis without an epidural abscess. Left L3 and L4 hemilaminectomies with L3-L4 discectomy were performed. An inflammatory mass was seen in the L3-L4 disc space region extending to the left L3 foramen. RESULTS Culture specimens obtained during surgery from both the disc and epidural space speciated to Candida lusitaniae. The patient completed a 6-month course of fluconazole therapy. At 2-year follow-up, she continued to be asymptomatic, without any recurrence of infection or neurologic sequelae. CONCLUSIONS We report a case of C. lusitaniae spondylodiscitis after discography in an immunocompetent patient with long-term follow-up. Clinicians must maintain a high index of suspicion for discitis in patients who undergo this procedure. If discitis is suspected, culture specimens must be evaluated for fungal and mycobacterial organisms, even in the immunocompetent host. With proper surveillance, surgical intervention, and appropriate postoperative follow-up, this complication can be effectively managed with excellent long-term outcome.

Abstract
INTRODUCTION Invasive candidiasis has emerged over the last few decades as an increasingly important nosocomial problem for the critically ill, affecting around 2% of intensive care unit patients. Although poor outcomes associated with invasive candidiasis among critically ill patients may relate to severe underlying disease processes and delayed institution of antifungal therapy, inadequate dosing of antifungal agents may also contribute. AREAS COVERED This drug evaluation provides a critical appraisal of the published literature pertaining to the pharmacokinetics of fluconazole in critically ill, obese or severely burned patients, including those receiving acute renal replacement therapy. The pharmacodynamics of fluconazole is also covered, as well as the likely clinical implications for optimal dosing and the toxicity of fluconazole. Last, variations in fluconazole susceptibility patterns of Candida spp. are also discussed. EXPERT OPINION Recently, there has been an increased but geographically variable prevalence of non-albicans Candida spp., causing invasive candidiasis and an overall trend towards reduced fluconazole susceptibility. The pathophysiological changes of critical illness, coupled with a lack of dose finding studies, support the use of local susceptibility patterns to guide fluconazole dosing until such time as pharmacokinetic-pharmacodynamic information to guide optimal fluconazole dosing strategies and pharmacodynamic targets becomes available.

Abstract
More antifungal agents have reached clinical use in the past two decades than at any other time. The echinocandins have been a welcome addition to this group, with the latest being anidulafungin. There are several lines of evidence to support anidulafungin’s role as primary therapy for the treatment of invasive candidiasis in non-neutropenic patients, and as alternative therapy to fluconazole in patients with esophageal candidiasis with azole intolerance or triazole-resistant Candida. Pharmacokinetic–pharmacodynamic studies in animals have demonstrated superior efficacy, defined as maximal microbial kill, when compared to fluconazole, regardless of the fluconazole susceptibility of the Candida species. These studies, as well as dose-effect studies in patients, also support the currently recommended dose of anidulafungin. A well designed randomized controlled trial has demonstrated anidulafungin’s efficacy in patients with invasive candidiasis. In this paper, we argue that anidulafungin may be preferable to fluconazole for the treatment of candidemia. However, as of yet, the difference between anidulafungin and the other two licensed echinocandins as first-line therapy for invasive candidiasis is unclear. On the other hand, there is insufficient evidence as of yet to support first-line use of anidulafungin in patients with neutropenia or aspergillosis.

Abstract
Fungal infections are of great relevance in surgical intensive care and Candida species represent the predominant part of fungal pathogens. Invasive aspergillosis is also relevant especially in patients with chronic pulmonary diseases. It is crucial for therapy success to begin adequate antifungal treatment at an early stage of the disease. Risk stratification of individual patient symptoms is essential for therapy timing. In case of suspected or proven candida infection, fluconazole is the agent of choice when the patient is clinically stable and no azoles have been administrated in advance and the local epidemiology makes azol resistance unlikely. For clinically instable patients with organ dysfunction the echinocandins serve as primary therapy because of their broad spectrum and reasonable safety profile. Due to a relevant proportion of azole resistant Candida species, susceptibility testing should be done routinely. Depending on the species detected de-escalating to an azole is feasible if organ dysfunctions have resolved. An invasive aspergillosis is primarily treated with voriconazole.

Abstract
The introduction of several new antifungals has significantly expanded both prophylaxis and treatment options for invasive fungal infections (IFIs). Relative to amphotericin B deoxycholate, lipid-based formulations of amphotericin B have significantly reduced the incidence of nephrotoxicity, but at a significant increase in drug acquisition cost. Newer, broad-spectrum triazoles (notably voriconazole and posaconazole) have added significantly to both the prevention and treatment of IFIs, most notably Aspergillus spp. (with voriconazole) and the treatment of some emerging fungal pathogens. Finally, a new class of parenteral antifungals, the echinocandins, is employed most frequently against invasive candidal infections. While the role of these newer agents continues to evolve, this review summarizes the activity, safety and clinical applications of agents most commonly employed in the treatment of IFIs.
