Initial micafungin treatment does not improve outcomes compared to fluconazole treatment in immunocompromised and critically ill patients with candidaemia. J Antimicrob Chemother 2024; 79:1877-1884. [PMID: 38831614 PMCID: PMC11290885 DOI: 10.1093/jac/dkae175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Accepted: 05/13/2024] [Indexed: 06/05/2024] Open
Abstract
BACKGROUND Candidaemia is associated with poor outcomes including high mortality rates. Controversy remains regarding whether fluconazole or an echinocandin is the optimal choice for initial candidaemia treatment, particularly among high-risk patients such as the immunocompromised or critically ill. OBJECTIVES To understand optimal initial treatment of candidaemia. METHODS We conducted a retrospective study of immunocompromised or ICU adult patients with candidaemia from 2010 to 2014. Patients who received ≥3 consecutive days of initial treatment with fluconazole or micafungin were included. The primary outcome was complete response at day 14, defined as clinical improvement and blood culture sterilization. Secondary outcomes included microbiological and clinical success, survival and recurrent candidaemia. RESULTS A total of 197 patients were included; 76 received fluconazole and 121 received micafungin. There was no difference in complete response between the fluconazole and micafungin groups (ICU: 38% versus 40%, P = 0.87; immunocompromised: 57% versus 59%, P = 0.80). Secondary outcomes including survival were also similar. In multivariable analysis, among ICU patients, Pitt bacteraemia score < 4 (P = 0.002) and time to antifungal (P = 0.037) were associated with meeting the primary outcome; white blood cell count > 11 cells × 103/µL on day 0 (P < 0.001) and Candida isolated from a non-blood site (P = 0.025) were associated with not meeting the primary outcome. Among immunocompromised patients, white blood cells > 11 × 103/µL (P = 0.003) and Candida isolated from a non-blood site (P = 0.026) were associated with not meeting the primary outcome. CONCLUSIONS These data suggest that among ICU or immunocompromised patients, severity of illness rather than initial antifungal choice drove clinical outcomes.

Abstract
Recognising the growing global burden of fungal infections, the World Health Organization (WHO) established an advisory group consisting of experts in fungal diseases to develop a Fungal Priority Pathogen List. Pathogens were ranked based on their research and development needs and perceived public health importance using a series of global surveys and pathogen characteristics derived from systematic reviews. This systematic review evaluates the features and global impact of invasive disease caused by Candida glabrata (Nakaseomyces glabrata). PubMed and Web of Science were searched for studies reporting on mortality, morbidity (hospitalization and disability), drug resistance (including isolates from sterile and non-sterile sites, since these reflect the same organisms causing invasive infections), preventability, yearly incidence, diagnostics, treatability, and distribution/emergence in the last 10 years. Candida glabrata (N. glabrata) causes difficult-to-treat invasive infections, particularly in patients with underlying conditions such as immunodeficiency, diabetes, or those who have received broad-spectrum antibiotics or chemotherapy. Beyond standard infection prevention and control measures, no specific preventative measures have been described. We found that infection is associated with high mortality rates and that there is a lack of data on complications and sequelae. Resistance to azoles is common and well described in echinocandins-in both cases, the resistance rates are increasing. Candida glabrata remains mostly susceptible to amphotericin and flucytosine. However, the incidence of the disease is increasing, both at the population level and as a proportion of all invasive yeast infections, and the increases appear related to the use of antifungal agents.

[PMID: 38249542 PMCID: PMC10799587 DOI: 10.1177/20499361231224980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Accepted: 12/19/2023] [Indexed: 01/23/2024] Open
Abstract
Invasive fungal infections are increasingly encountered with the expansion of iatrogenic immunosuppression, including not only solid organ and hematopoietic stem cell transplant recipients but also patients with malignancies or autoimmune diseases receiving immunomodulatory therapies, such as Bruton Tyrosine Kinase (BTK) inhibitor. Their attributable mortality remains elevated, part of which is a contribution from globally emerging resistance in both molds and yeasts. Because antifungal susceptibility test results are often unavailable or delayed, empiric and tailored antifungal approaches including choice of agent(s) and use of combination therapy are heterogeneous and often based on clinician experience with knowledge of host's net state of immunosuppression, prior antifungal exposure, antifungal side effects and interaction profile, clinical severity of disease including site(s) of infection and local resistance data. In this review, we aim to summarize previous recommendations and most recent literature on treatment of invasive mold and yeast infections in adults to guide optimal evidence-based therapeutic approaches. We review the recent data that support use of available antifungal agents, including the different triazoles that have now been studied in comparison to previously preferred agents. We discuss management of complex infections with specific emerging fungi such as Scedosporium spp., Fusarium spp., Trichosporon asahii, and Candida auris. We briefly explore newer antifungal agents or formulations that are now being investigated to overcome therapeutic pitfalls, including but not limited to olorofim, rezafungin, fosmanogepix, and encochleated Amphotericin B. We discuss the role of surgical resection or debridement, duration of treatment, follow-up modalities, and need for secondary prophylaxis, all of which remain challenging, especially in patients chronically immunocompromised or awaiting more immunosuppressive therapies.

Abstract
Background Deep fungal infection is a type of life-threatening opportunistic infection. Its incidence has been increasing in recent years. This infection can affect the prognosis of patients, prolong hospital stays and raise costs for patients and their families. Objective We aimed to understand the current situation of deep fungal infections in the First Affiliated Hospital of Kunming Medical University and to provide a basis for the clinical diagnosis and treatment of deep fungal infections. Methods This was a retrospective analysis of 528,743 cases in the hospital from 2015 to 2019, including the epidemiological characteristics, treatment and prognosis of deep fungal infections. Results A total of 274 cases (0.05%) with deep fungal infections were identified, accounting for 0.05% of the total number of hospitalizations. The incidence of deep fungal infections in the hospital showed an increasing trend from 2015 to 2019. The most commonly infected site was the respiratory tract (93.07%). Among patients with deep fungal infections, 266 specimens were positive for fungal culture, by which 161 cultured Candida albicans (C. albicans), accounting for 60.53%, the main pathogen causing deep fungal infection. From 2015 to 2019, the percentage of C. albicans cases showed a downward trend, while that of non-C. albicans showed an opposite trend. Antibiotics were the most common predisposing factor for deep fungal infections (97.45%). Among the underlying diseases of patients with deep fungal infections, infectious diseases (59.49%) were the most common. Those with underlying diseases such as renal insufficiency and neurological diseases had a worse prognosis. Indwelling catheters, nervous system disease and tumors were risk factors for a poor prognosis. Conclusions We report for the first time the epidemiological data of deep fungal infections in a general hospital in southwestern China from 2015 to 2019. In the past 5 years, the number of patients with deep fungal infections in the First Affiliated Hospital of Kunming Medical University has been increasing. Although the clinical data are limited, these results can provide references for the diagnosis and treatment of deep fungal infections.

Combination of Sequential Organ Failure Assessment (SOFA) score and Charlson Comorbidity Index (CCI) could predict the severity and prognosis of candidemia more accurately than the Acute Physiology, Age, Chronic Health Evaluation II (APACHE II) score. BMC Infect Dis 2021; 21:77. [PMID: 33451284 PMCID: PMC7811217 DOI: 10.1186/s12879-020-05719-8] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2019] [Accepted: 12/18/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Candidemia has emerged as an important nosocomial infection, with a mortality rate of 30-50%. It is the fourth most common nosocomial bloodstream infection (BSI) in the United States and the seventh most common nosocomial BSI in Europe and Japan. The aim of this study was to assess the performance of the Sequential Organ Failure Assessment (SOFA) score for determining the severity and prognosis of candidemia. METHODS We performed a retrospective study of patients admitted to hospital with candidemia between September 2014 and May 2018. The severity of candidemia was evaluated using the SOFA score and the Acute Physiology, Age, Chronic Health Evaluation II (APACHE II) score. Patients' underlying diseases were assessed by the Charlson Comorbidity Index (CCI). RESULTS Of 70 patients enrolled, 41 (59%) were males, and 29 (41%) were females. Their median age was 73 years (range: 36-93 years). The most common infection site was catheter-related bloodstream infection (n=36, 51%).The 30-day, and in-hospital mortality rates were 36 and 43%, respectively. Univariate analysis showed that SOFA score ≥5, APACHE II score ≥13, initial antifungal treatment with echinocandin, albumin < 2.3, C-reactive protein > 6, disturbance of consciousness, and CCI ≥3 were related with 30-day mortality. Of these 7, multivariate analysis showed that the combination of SOFA score ≥5 and CCI ≥3 was the best independent prognostic indicator for 30-day and in-hospital mortality. CONCLUSIONS The combined SOFA score and CCI was a better predictor of the 30-day mortality and in-hospital mortality than the APACHE II score alone.

Abstract
Invasive fungal infections (IFIs) are associated with high mortality rates and timely appropriate antifungal therapy is essential for good outcomes. Emerging antifungal resistance among Candida and Aspergillus spp., the major causes of IFI, is concerning and has led to the increasing incorporation of in vitro antifungal susceptibility testing (AST) to guide clinical decisions. However, the interpretation of AST results and their contribution to management of IFIs remains a matter of debate. Specifically, the utility of AST is limited by the delay in obtaining results and the lack of pharmacodynamic correlation between minimal inhibitory concentration (MIC) values and clinical outcome, particularly for molds. Clinical breakpoints for Candida spp. have been substantially revised over time and appear to be reliable for the detection of azole and echinocandin resistance and for outcome prediction, especially for non-neutropenic patients with candidemia. However, data are lacking for neutropenic patients with invasive candidiasis and some non-albicans Candida spp. (notably emerging Candida auris). For Aspergillus spp., AST is not routinely performed, but may be indicated according to the epidemiological context in the setting of emerging azole resistance among A. fumigatus. For non-Aspergillus molds (e.g., Mucorales, Fusarium or Scedosporium spp.), AST is not routinely recommended as interpretive criteria are lacking and many confounders, mainly host factors, seem to play a predominant role in responses to antifungal therapy. This review provides an overview of the pre-clinical and clinical pharmacodynamic data, which constitute the rationale for the use and interpretation of AST testing of yeasts and molds in clinical practice.

Abstract
BACKGROUND Case reports and pharmacokinetic data suggest off-label echinocandin dosing may be needed to reach adequate serum concentrations in obese patients. Few outcome studies exist evaluating this population. OBJECTIVES Of this study were to (1) determine the association of body mass index (BMI) with clinical outcomes of candidemia patients on standard doses of anidulafungin and (2) characterize fungal infections by body weight. METHODS A retrospective cohort was conducted to evaluate hospitalized patients treated for candidemia with anidulafungin at Food and Drug Administration-labeled dosing for at least 72 hours from January 1, 2014, through January 31, 2018. Candidemia was diagnosed by blood culture or T2 magnetic resonance (T2MR). Patients were compared according to BMI category. RESULTS One hundred seventy-three patients were included. Candida albicans and Candida glabrata were identified in 58 (33%) and 57 (33%) patients, respectively. Mortality was comparable according to BMI category: 4 (36.4%) underweight, 8 (25.8%) normal weight, 16 (32.0%) overweight, 20 (33.9%) obese, and 7 (31.8%) morbidly obese, P = .976. Variables associated with mortality included: severe sepsis (adjusted odds ratio [OR] = 5.1, 95% CI: 1.7-14.8) and liver disease (adjusted OR = 3.2, 95% CI: 1.1-9.4). Variables that were protective of mortality included: line removal (adjusted OR = 0.05, 95% CI: 0.02-0.2) and receipt of anidulafungin for at least 5 days (adjusted OR = 0.35, 95% CI: 0.15-0.8). CONCLUSION There was no difference detected in mortality among patients with candidemia across BMI category. Larger studies are needed to confirm whether standard doses of anidulafungin are sufficient for candidemia in obese patients.

Abstract
BACKGROUND Invasive fungal infections (IFIs) represent a global issue and affect various patient populations. In recent years, resistant fungal isolates showing increased azole or echinocandin MICs have been reported, and their potential clinical impact has been investigated. AIMS To provide an update on the epidemiology of resistance among fungi (e.g., Candida spp., Aspergillus spp., and Cryptococcus spp.) and to offer a critical appraisal of the relevant literature regarding the impact of MICs on clinical outcome in patients with IFI. SOURCES PubMed search with relevant keywords along with a personal collection of relevant publications. CONTENT Although antifungal resistance has been associated with a poorer response to antifungal therapy in various studies, other factors such as comorbidities, septic shock and source of infection appear to be key determinants affecting the clinical outcome of patients with IFI. IMPLICATIONS Future international collaborative studies are required to tease out the relative contribution of in vitro antifungal resistance on patient outcomes, thus enabling the optimization of IFI management.

Wang Y, McGuire TM, Hollingworth SA, Dong Y, Van Driel ML. Antifungal agents for invasive candidiasis in non-neutropenic critically ill adults: What do the guidelines recommend? Int J Infect Dis 2019; 89:137-145. [PMID: 31639522 DOI: 10.1016/j.ijid.2019.10.016] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2019] [Revised: 10/07/2019] [Accepted: 10/13/2019] [Indexed: 12/13/2022] Open
Abstract
OBJECTIVES Recommendations in clinical practice guidelines (CPG) may differ and cause confusion. Our objective was to appraise CPGs for antifungal treatment of invasive candidiasis (IC) in non-neutropenic critically ill adult patients. METHODS We systematically searched the literature for CPGs published between 2008 and 2018. We assessed the quality of each guideline using six domains of the AGREE II instrument. We extracted and compared recommendations for different treatment strategies and assessed content quality. RESULTS Of 19 guidelines, the mean overall AGREE II score was 58%. The domain 'clarity of presentation' received the highest scores (88%) and 'applicability' the lowest (18%). CPGs provided detailed recommendations on antifungal prophylaxis (n = 10), with fluconazole recommended as initial prophylaxis in all seven CPGs citing a specific drug. Echinocandin was recommended as the initial drug in all 16 CPGs supporting empirical/pre-emptive treatment; and in 18 of 19 for targeted invasive candidiasis treatment. However, it remains unclear when to initiate prophylaxis, empirical or pre-emptive therapy or when to step down. CONCLUSIONS The methodological quality of CPGs for antifungal treatment of IC in non-neutropenic critically ill patients is suboptimal. Some treatment recommendations were inconsistent across indications and require local guidance to help clinicians make better informed decisions.

Abstract
A modification of fluconazole formulation in the VITEK2 AST-YS08 card revoked the fluconazole-Candida glabrata combination. An evaluation of AST-YS08 following C. glabrata to C. albicans adjustment within VITEK2 software revealed higher fluconazole MICs compared to AST-YS07 and E-test, with major discrepancies. This mandates an alternative approach to fluconazole-C. glabrata susceptibility testing.

Abstract
OBJECTIVE The objective of this study was to evaluate the impact of the empirical therapy with fluconazole or an echinocandin on 30- and 90-day mortality in critically ill patients with candidemia. The outcome of patients in whom the empirical echinocandin was deescalated to fluconazole was also assessed. DESIGN Retrospective, observational multicenter study. SETTING Medical and surgical ICUs in nine Spanish hospitals. PATIENTS Adult patients (≥ 18 yr) with an episode of Candida bloodstream infection during ICU admission from January 2011 to April 2016. INTERVENTIONS Patient characteristics, infection-related variables, therapeutic interventions, and metastatic complications were reviewed. A propensity score-adjusted multivariable analysis was performed to identify the risk factors significantly associated with 30-day and 90-day mortality. MEASUREMENTS AND MAIN RESULTS A total of 294 patients were diagnosed of candidemia in the participant ICUs. Sixty patients were excluded (other antifungals in the primary therapy or the patient died without empirical antifungal therapy). The study group comprised 115 patients who received fluconazole (30-day mortality, 37.4%) and 119 patients treated empirically with an echinocandin (30-day mortality, 31.9%). The use of an echinocandin in the empirical therapy was a protective factor for 30-day (odds ratio, 0.32; 95% CI, 0.16-0.66; p = 0.002) and 90-day mortality (odds ratio, 0.50; 95% CI, 0.27-0.93; p = 0.014) in the propensity score- adjusted multivariable analysis. Deescalation of the empirical echinocandin to fluconazole was not associated with a higher mortality or the occurrence of long-term complications. CONCLUSIONS Empirical use of an echinocandin in critically ill patients with documented candidemia reduces mortality at 30 and 90 days significantly. Deescalation of the empirical echinocandin to fluconazole is safe and effective in fluconazole-susceptible infections.

Abstract
To evaluate clinical features and prognostic factors of non-albicans candidemia, we conducted a retrospective multicenter cohort study at 7 university hospitals in Korea from January 2010 to February 2016. A total of 721 patients with non-albicans candidemia were included in the analysis. C. tropicalis was most commonly identified (36.5%), followed by C. glabrata (27.2%), C. parapsilosis (25.7%), and C. krusei (2.4%). Clinical presentation of C. tropicalis candidemia was most severe with highest median C-reactive protein level (10.1 mg/dL) and Acute Physiology and Chronic Health Evaluation II score (14, both P ≪ 0.05). C. tropicalis showed the highest 14- and 30-day mortality (28.9% and 44.1%). In multivariate analysis, C. tropicalis infection was significantly related with 14- (P = 0.005) and 30-day mortality (P = 0.033). In conclusion, C. tropicalis infection presented most severely and showed worst clinical outcome among non-albicans candidemia.

Abstract
Vulvovaginal candidiasis is a common gynecologic diagnosis that can be treated empirically with fluconazole. We present a patient that developed post-operative Candida glabrata (C. glabrata) fungemia after being empirically treated for vulvuovaginal candidiasis with fluconazole multiple times throughout the year prior to robotic total laparoscopic hysterectomy and bilateral salpingo-oophorectomy. C. glabrata is becoming increasingly resistant to azole antimycotic therapy. It is likely that this patient had undertreated fluconazole-resistant C. glabrata vulvovaginitis prior to surgery, and that the pelvic infection was the source of fungemia.

Abstract
The purpose of this review is to critically analyze published data evaluating the impact of azole pharmacokinetic and pharmacodynamic parameters, MICs, and Candida species on clinical outcomes in patients with candidemia. Clinical breakpoints (CBPs) for fluconazole and voriconazole, which are used to determine susceptibility, have been defined by the Clinical and Laboratory Standards Institute (CLSI) for Candida species. Studies evaluating the relationship between treatment efficacy and in vitro susceptibility, as well as the pharmacodynamic targets, have been conducted in patients treated with fluconazole for candidemia; however, for species other than Candida albicans and Candida glabrata, and for other forms of invasive candidiasis, data remain limited and randomized trials are not available. Limited data evaluating these relationships with voriconazole are available. While pharmacodynamic targets for posaconazole and isavuconazole have been proposed based upon studies conducted in murine models, CBPs have not been established by CLSI. Fluconazole remains an important antifungal agent for the treatment of candidemia, and data supporting its use based on in vitro susceptibility are growing, particularly for C. albicans and C. glabrata Further investigation is needed to establish the roles of voriconazole, posaconazole, and isavuconazole in the treatment of candidemia and for all agents in the treatment of other forms of invasive candidiasis.

Abstract
OBJECTIVES The study aims to assess the population pharmacokinetics of fluconazole and the adequacy of current dosages and breakpoints against Candida albicans and non-albicans spp. in liver transplant (LT) patients. PATIENTS AND METHODS Patients initiated i.v. fluconazole within 1 month from liver transplantation (LTx) for prevention or treatment of Candida spp. infections. Multiple assessments of trough and peak plasma concentrations of fluconazole were undertaken in each patient by means of therapeutic drug monitoring. Monte Carlo simulations were performed to define the probability of target attainment (PTA) with a loading dose (LD) of 400, 600, and 800 mg at day 1, 7, 14, and 28 from LTx, followed by a maintenance dose (MD) of 100, 200, and 300 mg daily of the pharmacokinetic/pharmacodynamic target of AUC24h/MIC ratio ≥ 55.2. RESULTS Nineteen patients were recruited. A two-compartment model with first-order intravenous input and first-order elimination was developed. Patient's age and time elapsed from LTx were the covariates included in the final model. At an MIC of 2 mg/L, a LD of 600 mg was required for optimal PTAs between days 1 and 20 from LTx, while 400 mg was sufficient from days 21 on. A MD of 200 mg was required for patients aged 40-49 years old, while a dose of 100 mg was sufficient for patients aged ≥ 50 years. CONCLUSIONS Fluconazole dosages of 100-200 mg daily may ensure optimal PTA against C. albicans, C. parapsilosis, and C. tropicalis. Higher dosages are required against C. glabrata. Estimated creatinine clearance is not a reliable predictor of fluconazole clearance in LT patients.

Abstract
To evaluate the impacts of fluconazole minimum inhibitory concentration (MIC) according to primary antifungal agents on Candida glabrata bloodstream infection (BSI), a multicenter retrospective cohort study was conducted in Korea, concerning the time period from January 2010 to February 2016. A total of 197 adult patients with C. glabrata BSI were included in the study, and neutropenia (P = 0.026), APACHE II score (P = 0.004), and fluconazole resistance (HR 3.960, 95% CI 1.395-11.246, P = 0.010) were associated with 30-day mortality in multivariate analysis. In subgroup analysis, fluconazole MIC = 32 μg/mL in the azole-treated group (HR 6.691, 95% CI 1.569-28.542, P = 0.010) and fluconazole MIC ≥ 64 μg/mL in the non-azole-treated group (HR 3.337, 95% CI 1.183-9.411, P = 0.023) showed the highest hazard ratio (HR) for 30-day mortality. Increased fluconazole MIC was associated with poor outcome both in azole- and non-azole-treated patients with C. glabrata BSI.

Abstract
Candida species remains one of the most important causes of opportunistic infections worldwide. Invasive candidiasis (IC) is associated with considerable morbidity and mortality in liver disease (LD) patients if not treated promptly. Echinocandins are often recommended as a first-line empirical treatment for managing IC and can especially play a critical role in managing IC in LD patients. However, advanced LD patients are often immunocompromised and critically ill. Hence altered pharmacokinetics, drug interactions as well as tolerance issues of antifungal treatments are a concern in these patients. This comprehensive review examines the epidemiology, risk factors and diagnosis of IC in patients with LD and evaluates differences between three available echinocandins for treating this group of patients.

Abstract
Robust pharmacodynamic indices that align fluconazole dose or exposure with outcomes in invasive candidiasis due to Candida glabrata remain elusive. The purpose of this retrospective multicenter study was to evaluate a cohort of 127 patients with C. glabrata fungemia treated with fluconazole, using adjusted analyses to identify risk factors for 28-day death. No significant correlations were found between fluconazole area under the curve (AUC), AUC/MIC ratio, or MIC and survival. In multivariate logistic regression analyses, however, higher average fluconazole dose (odds ratio [OR], 1.006 [95% confidence interval [CI], 1.001 to 1.010]; P = 0.008), average fluconazole dose of ≥400 mg (OR, 3.965 [95% CI, 1.509 to 10.418]; P = 0.005), and higher fluconazole dose on day 1 of therapy (OR, 1.007 [95% CI, 1.002 to 1.011]; P = 0.002) were found to be independent predictors of 28-day survival. Additionally, the presence of a central venous catheter at the time of infection was found to be a significant risk factor for death. In conclusion, we found fluconazole dose to be an independent predictor of 28-day survival for patients with C. glabrata fungemia, with doses of ≥400 mg/day being associated with 28-day survival rates approaching 90%. These data indicate the use and efficacy of fluconazole in the treatment of this serious infection. Aggressive dosing appears to be necessary when fluconazole is used for the treatment of C. glabrata fungemia, irrespective of MIC.

Abstract
BACKGROUND Candidemia is one of the most common nosocomial bloodstream infections. Early diagnosis and antifungal treatment improve clinical outcomes in some studies but not all, with diverse data reported from different institutions. Similarly, antifungal resistance is more common in the USA than in Europe, but there is little data regarding the microbiology and clinical course of candidemia in adult patients in Asia. AIMS (1) To capture species distribution and drug resistance rates among Candida bloodstream isolates, (2) to describe clinical features of candidemia, and (3) to identify factors associated with all-cause mortality, with emphasis on early initiation of antifungal treatment, at a large tertiary University Hospital in China. METHODS In this single-center retrospective study, we identified all patients with candidemia, between 2008 and 2014. Demographic and clinical characteristics, microbiological information, details of antifungal therapy and clinical outcomes were collected. RESULTS We studied 166 patients. 71 (42.8%) had cancer. Candida albicans was the most frequent species (37.3%), followed by C. parapsilosis (24.1%), C. tropicalis (22.8%), and C. glabrata (14.5%). Antifungal resistance was more frequent in non-albicans strains and especially C. glabrata. Twenty patients received inappropriate treatment with all-cause mortality of 35%. The remaining 146 patients had significantly lower mortality (21.9%, P = 0.045). Among patients who received antifungal treatment, mortality rate increased with time to appropriate antifungal therapy (AAT): 13.7%, for < 24 h, 21.1% for 24-48 h, 23.1% for > 48 h, and 32.4% among patients who received no AT (χ2 for trend P = 0.039). Initiating AAT more than 24 h after blood culture collection was an independent risk factor for mortality, after adjustment for other confounders (OR 7.1, 95% CI 1.3-39.4, P = 0.024). CONCLUSIONS Candida albicans was the most frequent cause of candidemia at a large tertiary hospital in China, but antifungal resistance is a growing concern among non-albicans Candida species. The mortality rate of patients treated with ineffective antifungal agents based on in vitro susceptibilities was similar to that of patients who received no treatment at all, and delayed initiation of antifungal treatment was associated with increased risk of death.

Abstract
Background Whether echinocandins could be used to treat candidemia of a urinary tract source (CUTS) is unknown. We aimed to provide current epidemiological information of CUTS and to compare echinocandin to fluconazole treatment on CUTS outcomes. Methods A multicenter study of adult patients with candidemia was conducted in 9 hospitals. CUTS was defined as a candidemia with concomitant candiduria by the same organism associated with significant urological comorbidity. The primary outcome assessed was clinical failure (defined by 7-day mortality or persistent candidemia) in patients treated with either an echinocandin or fluconazole. A propensity score was calculated and then entered into a regression model. Results Of 2176 episodes of candidemia, 128 were CUTS (5.88%). Most CUTS cases were caused by Candida albicans (52.7%), followed by Candida glabrata (25.6%) and Candida tropicalis (16.3%). Clinical failure occurred in 7 patients (20%) treated with an echinocandin and in 15 (17.1%) treated with fluconazole (P = .730). Acute renal failure (adjusted odds ratio [AOR], 3.01; 95% confidence interval [CI], 1.01-8.91; P = .047) was the only independent factor associated with clinical failure, whereas early urinary tract drainage procedures (surgical, percutaneous, or endoscopic) were identified as protective (AOR, 0.08; 95% CI, .02-.31; P < .001). Neither univariate nor multivariate analysis showed that echinocandin therapy altered the risk of clinical failure. Conclusions Initial echinocandin therapy was not associated with clinical failure in patients with CUTS. Notably, acute renal failure predicted worse outcomes and performing an early urologic procedure was a protective measure.

Abstract
The treatment of invasive candidiasis has changed greatly in the past decade and must continue to evolve if we are to improve outcomes in this serious infection. A review of recent history may provide insights for the future. The morbidity and mortality of invasive candidiasis remain difficult to measure despite an obvious clinical burden. Current treatment guidelines now recommend echinocandins as first-line empirical treatment, with fluconazole as an acceptable alternative for selected patients, reflecting the efficacy demonstrated by echinocandins and increasing resistance observed with fluconazole. The selection of antifungal therapy now must consider not only resistance but also the shift in predominance from Candida albicans to non-albicans species, notably Candida glabrata. The recent emergence of Candida auris has been met with great interest, although the longer-term implications of this phenomenon remain unclear. The broad goal of treatment continues to be administration of safe, efficacious antifungal therapy as soon as possible. Diagnostic methods beyond traditional blood culture present an opportunity to shorten the time to an accurate diagnosis, and earlier treatment initiation based on prophylactic and empirical or pre-emptive strategies seeks to ensure timely therapeutic intervention. In addition, there are novel agents in the antifungal pipeline. These developments, as well as ongoing studies of dosing, toxicity and resistance development, are important items on the current research agenda and may play a role in future changes to the treatment of invasive candidiasis.

Abstract
The 28-day crude mortality rate in 68 cancer patients with fluconazole-susceptible dose-dependent Candida glabrata fungemia started on treatment (within 48 h after blood culture collection) with an echinocandin or liposomal amphotericin-B was better (30%) than those treated with azole monotherapy (52%) (P = 0.07). After adjusting for confounders, azole monotherapy also was associated with worse 28-day survival (hazard ratio, 3.8; P = 0.003).

Abstract
PURPOSE To describe concisely the current standards of care, major recent advances, common beliefs that have been contradicted by recent trials, areas of uncertainty, and clinical studies that need to be performed over the next decade and their expected outcomes with regard to Candida and Aspergillus infections in non-neutropenic patients in the ICU setting. METHODS A systematic review of the medical literature taking account of national and international guidelines and expert opinion. RESULTS Severe invasive fungal infections (IFIs) are becoming increasingly frequent in critically ill patients. Approximately 80% of IFIs are due to Candida spp. and 0.3-19% to Aspergillus spp. Recent observations emphasize the necessity of building a worldwide sentinel network to monitor the emergence of new fungal species and changes in susceptibility. Robust data on the attributable mortality are essential for the design of clinical studies with mortality endpoints. Although early antifungal therapy for Candida has been recommended in patients with risk factors, sepsis of unknown cause, and positive Candida serum biomarkers [β-1 → 3-D-glucan (BDG) and Candida albicans germ tube antibody (CAGTA)], its usefulness and influence on outcome need to be confirmed. Future studies may specifically address the optimal diagnostic and therapeutic strategies for patients with abdominal candidiasis. Better knowledge of the pharmacokinetics of antifungal molecules and tissue penetration is a key issue for intensivists. Regarding invasive aspergillosis, further investigation is needed to determine its incidence in the ICU, its relationship with influenza outbreaks, the clinical impact of rapid diagnosis, and the significance of combination treatment. CONCLUSIONS Fundamental questions regarding IFI have to be addressed over the next decade. The clinical studies described in this research agenda should provide a template and set priorities for the clinical investigations that need to be performed.

Abstract
Candida glabrata isolates have reduced in vitro susceptibility to azoles, which raises concerns about the clinical effectiveness of fluconazole for treating bloodstream infection (BSI) by this Candida species. We aimed to evaluate whether the choice of initial antifungal treatment (fluconazole versus echinocandins or liposomal amphotericin B [L-AmB]-based regimens) has an impact on the outcome of C. glabrata BSI. We analyzed data from a prospective, multicenter, population-based surveillance program on candidemia conducted in 5 metropolitan areas of Spain (May 2010 to April 2011). Adult patients with an episode of C. glabrata BSI were included. The main outcomes were 14-day mortality and treatment failure (14-day mortality and/or persistent C. glabrata BSI for ≥48 h despite antifungal initiation). The impact of using fluconazole as initial antifungal treatment on the patients' prognosis was assessed by logistic regression analysis with the addition of a propensity score approach. A total of 94 patients with C. glabrata BSI were identified. Of these, 34 had received fluconazole and 35 had received an echinocandin/L-AmB-based regimen. Patients in the echinocandin/L-AmB group had poorer baseline clinical status than did those in the fluconazole group. Patients in the fluconazole group were more frequently (55.9% versus 28.6%) and much earlier (median time, 3 versus 7 days) switched to another antifungal regimen. Overall, 14-day mortality was 13% (9/69) and treatment failure 34.8% (24/69), with no significant differences between the groups. On multivariate analysis, after adjusting for baseline characteristics by propensity score, fluconazole use was not associated with an unfavorable evolution (adjusted odds ratio [OR] for 14-day mortality, 1.16, with 95% confidence interval [CI] of 0.22 to 6.17; adjusted OR for treatment failure, 0.83, with 95% CI of 0.27 to 2.61). In conclusion, initial fluconazole treatment was not associated with a poorer outcome than that obtained with echinocandins/L-AmB regimens in patients with C. glabrata BSI. (This study has been registered at ClinicalTrials.gov under registration no. NCT01236261.).

Abstract
PURPOSE OF REVIEW Invasive and mucosal candidiasis are associated with major morbidity in patients with inappropriate host defence mechanisms. This review focuses on recent studies elucidating the immune response against candidiasis and possible immunotherapeutic approaches. RECENT FINDINGS The last year has seen substantial advances in understanding antifungal immunity. The role of pattern recognition receptors and the Th1 and Th17 immune pathways has been further elucidated. The first genome-wide studies have identified new risk factors for candidaemia. Trials of adjuvant immunotherapy for fungal infections have provided directions for the future. SUMMARY Understanding the fungal pathogenesis and the induction of protective antifungal adaptive immunity has advanced the development of immunotherapeutic strategies and vaccines against invasive and mucosal candidiasis.

Abstract
Targeting fluconazole therapy to achieve predefined pharmacodynamic goals has been suggested as a means of optimizing the treatment of patients with candidaemia. However, data regarding species-specific dosing targets are inconclusive. We retrospectively analysed a cohort of 75 adult patients with Candida bloodstream infection (BSI) who received initial treatment with fluconazole for ≥48 h (36 Candida albicans and 39 non-albicans Candida (NAC)). Fluconazole dose, the dose/MIC ratio and the 24-h area under the concentration-time curve (AUC24)/MIC ratio were determined for each patient, and classification and regression tree analysis was used to determine breakpoints for significant interactions with 30-day survival. Both fluconazole exposure parameters and patient-related and disease-related variables were assessed in univariable and multivariable survival models. The crude 30-day mortality rate was 32% (44% and 21% for C. albicans and NAC, respectively). An average fluconazole dose of >200 mg/day, a dose/MIC ratio of >400 and an AUC24/MIC ratio of >400 were associated with a higher 30-day survival rate and better microbiological response in patients with C. albicans BSI but not in those with NAC BSI. Baseline chronic kidney disease was a risk factor for fluconazole underdosing and mortality. Severity of sepsis (Sequential Organ Failure Assessment score) was the only significant predictor of death in patients with NAC BSI. We conclude that, although pharmacodynamic target-directed fluconazole dosing may help to optimize outcomes for patients with C. albicans BSI, additional studies are needed to define the role of fluconazole in the treatment of NAC BSI.

Abstract
OBJECTIVE Candidemia is among the most common nosocomial bloodstream infections and is associated with high mortality, increased length of hospital stay, and significant economic burden. The introduction of the echinocandins in the 2000s has expanded the armamentarium against Candida spp and provides therapeutic options that are effective, safe, and tolerable. Although the Infectious Diseases Society of America favors echinocandins as treatment for candidemia in selected settings (at least as initial therapy), there remain divergent opinions about whether an echinocandin or fluconazole is the preferred agent for candidemia, and clinical practice guidelines are in flux. In this review, the currently available laboratory and clinical data are summarized and critically evaluated. DATA SOURCES A MEDLINE search of the English language literature was performed using the search terms echinocandin, fluconazole, and candidemia. References of review articles and guidelines were also screened for inclusion. STUDY SELECTION AND DATA EXTRACTION Studies whose primary goal was to compare echinocandins with fluconazole were evaluated as well as studies that differentiated pharmacological and pharmacokinetic properties between agents. DATA SYNTHESIS It is clear that echinocandins and fluconazole each have roles in the management of candidemia. Specific recommendations are provided that will hopefully optimize outcomes in candidemia while incorporating stewardship concepts of cost-effectiveness and limiting the emergence of resistance. CONCLUSIONS Despite the advantages brought by the echinocandins and fluconazole, outcomes among patients with candidemia remain suboptimal. Improved treatment of candidemia may ultimately be achieved by optimizing the use of antifungal agents rather than the development of new drugs.

Abstract
Reference broth microdilution methods of Candida echinocandin susceptibility testing are limited by interlaboratory variability in caspofungin MICs. Recently revised Clinical and Laboratory Standards Institute (CLSI) breakpoint MICs for echinocandin nonsusceptibility may not be valid for commercial tests employed in hospital laboratories. Indeed, there are limited echinocandin susceptibility testing data from hospital laboratories. We conducted a multicenter retrospective study of 9 U.S., Australian, and New Zealand hospitals that routinely tested Candida bloodstream isolates for echinocandin susceptibility from 2005 to 2013. Eight hospitals used Sensititre YeastOne assays. The Candida spp. were C. albicans (n=1,067), C. glabrata (n=911), C. parapsilosis (n=476), C. tropicalis (n=185), C. krusei (n=104), and others (n=154). Resistance and intermediate rates were ≤1.4% and ≤3%, respectively, for each echinocandin against C. albicans, C. parapsilosis, and C. tropicalis. Resistance rates among C. glabrata and C. krusei isolates were ≤7.5% and ≤5.6%, respectively. Caspofungin intermediate rates among C. glabrata and C. krusei isolates were 17.8% and 46.5%, respectively, compared to ≤4.3% and ≤4.4% for other echinocandins. Using CLSI breakpoints, 18% and 19% of C. glabrata isolates were anidulafungin susceptible/caspofungin nonsusceptible and micafungin susceptible/caspofungin nonsusceptible, respectively; similar discrepancies were observed for 38% and 39% of C. krusei isolates. If only YeastOne data were considered, interhospital modal MIC variability was low (within 2 doubling dilutions for each agent). In conclusion, YeastOne assays employed in hospitals may reduce the interlaboratory variability in caspofungin MICs against Candida species that are observed between reference laboratories using CLSI broth microdilution methods. The significance of classifying isolates as caspofungin intermediate and anidulafungin/micafungin susceptible will require clarification in future studies.

Abstract
AIMS Echinocandins are recommended for the treatment of candidaemia in moderately severe to severely ill patients. Step-down or de-escalation from echinocandin to fluconazole is advised in patients who are clinically stable but data in relation to step-down therapy are sparse. Using our hospital intravenous to oral switch therapy (IVOST) policy to guide antifungal de-escalation in patients with candidaemia, we aimed to determine what proportion of patients are de-escalated to fluconazole, the timescale to step-down, associated reduction in consumption of echinocandins and antifungal cost savings. METHODOLOGY Patients with candidaemia were followed from April 2011 to March 2013. RESULTS A total of 37 episodes of candidaemia were documented during the study period. Twenty-seven patients were commenced on an echinocandin or voriconazole and 19 (70.3%) were de-escalated to fluconazole based on the IVOST policy. The mean and median number of days to de-escalation of therapy was 4.6 and 5 days, respectively. One patient whose therapy was de-escalated relapsed. The overall 30 day crude mortality was 37.1%. The step-down approach led to significant saving in antifungal drug cost of £1133.88 per candidaemic episode and £2208.08 per de-escalation. CONCLUSION Implementation of IVOST policy led to streamlining of antifungal therapy.

Abstract
Mutations in Candida glabrata FKS genes, which encode the echinocandin target enzyme, are independent risk factors for treatment failures during invasive candidiasis. We retrospectively compared the ability of caspofungin susceptibility testing methods to identify C. glabrata FKS mutant isolates and predict outcomes among patients at our center. Eight percent (10/120) of sterile-site C. glabrata isolates harbored FKS1 (n = 3) or FKS2 (n = 7) mutations, including 32% (10/32) recovered from patients with prior echinocandin exposure. Median echinocandin exposures for mutant and nonmutant isolates were 55 (range, 7 to 188) and 13 (3 to 84) days, respectively (P = 0.004). Sensitivity and specificity of the CLSI caspofungin resistance breakpoint MIC (>0.12 μg/ml by broth microdilution using RPMI medium [BMD-RPMI]) were 90% (9/10) and 3% (3/110), respectively, for identifying FKS mutants. Sensitivity and specificity of receiver-operator characteristic (ROC) curve-derived breakpoints by BMD-RPMI, BMD-antibiotic medium 3, Etest, and YeastOne ranged from 70 to 100% and 89 to 95%, respectively; susceptibility rates varied from 83 to 90%. The 14-day echinocandin treatment success rate was 67% (44/66); failure was more likely with prior echinocandin exposure (P = 0.002) or infection with an FKS mutant (P = 0.0001) or echinocandin-resistant isolates by BMD-AM3, Etest, and YeastOne (P ≤ 0.03). The failure rate among patients with prior exposure and infection with a resistant isolate was 91% (10/11); it was 22% (12/55) among others (P < 0.0001). In conclusion, ROC-derived caspofungin MIC breakpoints by several methods were sensitive and specific for identifying C. glabrata FKS mutant isolates. Mutations were seen exclusively among patients with prior echinocandin exposure. A paradigm that considers prior echinocandin exposure and caspofungin MICs accurately classified treatment outcomes for C. glabrata invasive candidiasis.
