Abstract
Antifungal stewardship (AFS), compared with antimicrobial stewardship (AS), requires more advanced knowledge, skills, and multidisciplinary collaboration in its implementation. Therefore, fewer facilities are performing AFS compared with AS. At our hospital, we started AS and AFS in 2014. Our AFS programs include the following: i) interventions for patients with yeast-positive blood cultures, ii) introduction of a conditional antifungal notification system, and iii) commencement of AS team rounds. AFS for filamentous fungi includes bronchoscopy and microbial identification, including genetic and drug susceptibility testing. These AFS activities have improved several processes and outcome measures. However, our AFS team has faced several problems owing to the impact of COVID-19. This review introduces the practice of AFS, which we initiated at our hospital in 2014, and presents the current problems.

Albahar F, Alhamad H, Abu Assab M, Abu-Farha R, Alawi L, Khaleel S. The Impact of Antifungal Stewardship on Clinical and Performance Measures: A Global Systematic Review. Trop Med Infect Dis 2023; 9:8. [PMID: 38251205 PMCID: PMC10820751 DOI: 10.3390/tropicalmed9010008] [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: 07/17/2023] [Revised: 09/06/2023] [Accepted: 09/13/2023] [Indexed: 01/23/2024] Open
Abstract
BACKGROUND Antimicrobial stewardship programs (ASP) have been proposed as an opportunity to optimize antifungal use. The antifungal resistance is a significant and emerging threat. The literature on antifungal stewardship (AFS) and its influence on performance and clinical outcome measures is scarce. This study aimed to examine global evidence of the impact of AFS on patients and performance measures. METHODS The "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) was used for the flow of identification, screening, eligibility, and inclusion. PubMed and MEDLINE were searched using the term ''antifungal stewardship'' on 15 February 2023. Search terms included antifungal stewardship, antimicrobial stewardship, candida, candidemia, candiduria, and invasive fungal disease. Of the 1366 records, 1304 were removed since they did not describe an antifungal stewardship intervention. Among the 62 full texts assessed, 21 articles were excluded since they were non-interventional studies and did not include the outcome of interest. Thus, 41 articles were eligible for systematic review. Eligible studies were those that described an AFS program and evaluated clinical or performance measures. RESULTS Of the 41 included studies, the primary performance measure collected was antifungal consumption (22 of 41), and mortality (22 of 41), followed by length of stay (11 of 41) and cost (9 of 41). Most studies were single-center, quasi-experimental, with varying interventions across studies. The principal finding from most of the studies in this systematic review is a reduction in mortality expressed in different units and the use of antifungal agents (13 studies out of 22 reporting mortality). Antifungal consumption was significantly blunted or reduced following stewardship initiation (10 of 22). Comparing studies was impossible due to a lack of standard units, making conducting a meta-analysis unfeasible, which would be a limitation of our study. CONCLUSION It has been shown that AFS interventions may improve antifungal consumption and other performance measures. According to available published studies, antifungal consumption and mortality appear to be the possible performance measures to evaluate the impact of AFS.

Abstract
Antimicrobial stewardship refers to a well-coordinated program which promotes the scientific and rational use of antimicrobials, reduces the chances of drug resistance and improves patient outcomes. A comprehensive English language literature search was done across multiple databases (PubMed, EMBASE, MEDLINE and Cochrane) for the period 1990-2022, revealing a large volume of reports of growing resistance to established antifungal therapies, against a backdrop of irrational and unscientific prescriptions. As a result of this, antifungal stewardship, a new kid on the block, has recently garnered attention. This review article is an attempt to summarise the basic concept of stewardship programs, highlighting the dire need to implement the same in the present situation of antifungal resistance and treatment failure.

Abstract
BACKGROUND Invasive aspergillosis is one of the important causes of infection in immunocompromised patients. This study aimed to evaluate the roles of biomarkers in the diagnosis of invasive aspergillosis and their relationship with antifungal stewardship programs. METHODS 190 sera from 52 immunocompromised patients and volunteer individuals were included in this study. 18 immunocompromised volunteers without IA and 34 patients with probable and proven aspergillosis according to the European Organization for Research and Treatment of Cancer and the Mycoses Study Group consensus definitions were entered in this study. The respective sera were evaluated for procalcitonin, soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) levels; white blood cells count (WBC) count, C reactive protein (CRP), lactate dehydrogenase (LDH), and erythrocyte sedimentation rate (ESR) values. Demographic data and clinical characteristics of patients were extracted from their files. RESULTS The male-to-female ratio and mean age of patients were 22/12 and 38.9 years, respectively. The hematologic disorder was the most predisposing factor (29/34, 85.3%). Sensitivity of biomarkers for diagnosis of invasive aspergillosis was 70.6% (cut off value > 190 pg/mL for sTREM-1, 71% (cut off value > 260 pg/mL) for PCT, 85.3% (cut off value > 193 U/L) for LDH, 94.1% (cut off value > 8 mg/l) for CRP, 64.7% (cut off value < 5200 cells/ml) for WBC, and 85.3% (cut off value > 23 mm/h) for ESR. Twelve patients died, with significantly increased sTREM-1 levels and decreased WBC count in them. CONCLUSION According to our data, evaluation of the biomarkers can help in the diagnosis, management, and prediction of the severity of Aspergillus infection, and the rational use of antifungal agents in immunocompromised patients.

ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY : ASHE 2022; 2:e156. [PMID: 36483356 PMCID: PMC9726485 DOI: 10.1017/ash.2022.292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 07/28/2022] [Accepted: 08/01/2022] [Indexed: 06/17/2023]
Abstract
OBJECTIVE To evaluate the effect of templated microbiology reporting comments on antifungal utilization in patients with candiduria. DESIGN In this retrospective, quasi-experimental study, we evaluated a preimplementation cohort (June 2018-January 2019) compared with a postimplementation cohort (June 2019-January 2020). SETTING A multisite health system including 1 academic hospital and 4 community hospitals. PATIENTS Patients were aged ≥18 years, were hospitalized, and had candiduria documented at least once during their admission. The study included 156 patients in the preimplementation period and 141 patients in the postimplementation period. METHODS In June 2019, Saint Luke's Health System implemented the use of templated comments for urine cultures with Candida spp growth. When Candida is isolated, the following comment appears in the microbiology result section: "In the absence of symptoms, Candida is generally considered normal flora. No therapy indicated unless high risk (pregnant, neonate, or neutropenic) or undergoing urologic procedure. If Foley catheter present, remove or replace when able." The primary outcome was rate of antifungal prescribing. RESULTS Antifungal administration within 72 hours of a culture identifying a Candida spp occurred in 75 patients in the preimplementation group and 48 patients in the postimplementation group (48.1% vs 34.0%; P = .02). We did not detect a difference between groups in antifungal administration between 73 and 240 hours (1.3% vs 3.5%; P = .26), nor did we detect a difference in median antifungal duration (4 vs 3 days; P = .43). CONCLUSION Using a templated comment with urine cultures reduced antifungal prescription rates in hospitalized patients with candiduria. This strategy is a low-resource technique to improve antimicrobial stewardship.

Augmented Enterocyte Damage During Candida albicans and Proteus mirabilis Coinfection. Front Cell Infect Microbiol 2022; 12:866416. [PMID: 35651758 PMCID: PMC9149288 DOI: 10.3389/fcimb.2022.866416] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Accepted: 04/15/2022] [Indexed: 12/24/2022] Open
Abstract
The human gut acts as the main reservoir of microbes and a relevant source of life-threatening infections, especially in immunocompromised patients. There, the opportunistic fungal pathogen Candida albicans adapts to the host environment and additionally interacts with residing bacteria. We investigated fungal-bacterial interactions by coinfecting enterocytes with the yeast Candida albicans and the Gram-negative bacterium Proteus mirabilis resulting in enhanced host cell damage. This synergistic effect was conserved across different P. mirabilis isolates and occurred also with non-albicans Candida species and C. albicans mutants defective in filamentation or candidalysin production. Using bacterial deletion mutants, we identified the P. mirabilis hemolysin HpmA to be the key effector for host cell destruction. Spatially separated coinfections demonstrated that synergism between Candida and Proteus is induced by contact, but also by soluble factors. Specifically, we identified Candida-mediated glucose consumption and farnesol production as potential triggers for Proteus virulence. In summary, our study demonstrates that coinfection of enterocytes with C. albicans and P. mirabilis can result in increased host cell damage which is mediated by bacterial virulence factors as a result of fungal niche modification via nutrient consumption and production of soluble factors. This supports the notion that certain fungal-bacterial combinations have the potential to result in enhanced virulence in niches such as the gut and might therefore promote translocation and dissemination.

Abstract
Inappropriate antifungal use is prevalent and can lead to drug-resistant fungi, expose patients to adverse drug events, and increase healthcare costs. While antimicrobial stewardship programs have traditionally focused on antibiotic use, the need for targeted antifungal stewardship (AFS) intervention has garnered interest in recent years. Despite this, data on AFS in immunocompromised patient populations is limited. This paper will review the current state of AFS in this complex population and explore opportunities for multidisciplinary collaboration.

Abstract
In recent years, the global public health community has increasingly recognized the importance of antimicrobial stewardship (AMS) in the fight to improve outcomes, decrease costs, and curb increases in antimicrobial resistance around the world. However, the subject of antifungal stewardship (AFS) has received less attention. While the principles of AMS guidelines likely apply to stewarding of antifungal agents, there are additional considerations unique to AFS and the complex field of fungal infections that require specific recommendations. In this article, we review the literature on AMS best practices and discuss AFS through the lens of the global core elements of AMS. We offer recommendations for best practices in AFS based on a synthesis of this evidence by an interdisciplinary expert panel of members of the Mycoses Study Group Education and Research Consortium. We also discuss research directions in this rapidly evolving field. AFS is an emerging and important component of AMS, yet requires special considerations in certain areas such as expertise, education, interventions to optimize utilization, therapeutic drug monitoring, and data analysis and reporting.

Clinical and microbiological features of candiduria in critically ill adult patients in Shiraz, Iran (2016-2018): deviations from international guidelines and fluconazole therapeutic failure. Med Mycol 2020; 59:myaa092. [PMID: 33305331 DOI: 10.1093/mmy/myaa092] [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: 08/08/2020] [Accepted: 10/27/2020] [Indexed: 12/15/2022] Open
Abstract
Candiduria is common among patients admitted to intensive care units (ICUs); however, clinical and microbiological data are limited, which accounts for non-compliance with international guidelines, including over treatment of asymptomatic candiduria that promotes antifungal resistance. This prospective study included adult patients admitted to ICUs of five referral hospitals in Shiraz, Iran, during 2016-2018. Species were identified by MALDI-TOF MS, and antifungal susceptibility was assessed according to CLSI M27-A3/S4. Among 2086 patients, 162 and 293 developed candiduria and bacteriuria, respectively. In total, 174 yeast isolates were collected; 88.5% were Candida albicans (91/174; 52.2%), C. glabrata (38/174; 21.8%), and C. tropicalis (25/174; 14.3%). Antifungal resistance was rare; only two isolates (one C. tropicalis and one C. krusei) were fluconazole resistant. Symptomatic candiduria was noted in 31.4% of patients (51/162); only 37% (19/51) of them were treated and 36.82% (7/19) showed fluconazole therapeutic failure. Two symptomatic patients developed candidemia shortly after candiduria. Among asymptomatic patients, 31.5% (35/111) were overtreated with fluconazole. The mortality rate was 25.3% (41/162); it did not differ between symptomatic and asymptomatic patients. Our results indicate that deviation from standard-of-care treatment for candiduria is a matter of concern given the high rate of fluconazole therapeutic failure among patients with symptomatic candiduria. LAY SUMMARY Candiduria is an underestimated clinical presentation among critically ill patients and detailed data are scarce in this regard. Given the high rate of fluconazole therapeutic failure and development of candidemia in some cases, the mistreatment of candiduria should not be overlooked by clinicians.

Abstract
Candiduria are common findings in clinic especially in hospitalized patients, while its significance remains undetermined. Since there are few criteria to follow, physicians tended to make decisions by personal experience in many cases in clinical practice. The present study was designed to unveil the present situation of candiduria management in hospitalized patients in clinical practice. A total of 251 hospitalized candiduria patients were retrospectively enrolled in the study. Clinical data on patient demographics, basic conditions, catheter using, urinary symptoms, laboratory data, and antifungal therapies were obtained from electronic medical records. The high rate of the candiduria cases were managed inappropriately after the introduction of the Infectious Diseases Association of America (IDSA) evidence-based recommendations, both in the management of urinary catheter and antifungal agents. Overtreatment was common in asymptomatic candiduria patients. For symptomatic patients, improper drug selections were not rare. In addition, a part of candiduria patients did not receive antifungal therapies although the IDSA recommends. A statistically significant difference was only found in hospital charges of symptomatic candiduria patients managed following IDSA or not. The recurrence rate, mortality, and hospital stay length were similar in candiduria patients regardless of the clinical management. Physicians tend to start empiric antifungal therapy for candiduria patients with pneumonia, multisite of Candida colonization, higher urine Candida CFUs, and long hospital stay. Candiduria has not received special attention today, and empirical antifungal treatment is common. IDSA guidelines are important to standardize the management of candiduria in clinic; however, the significance of the guidelines needs to be further clarified in future multicenter investigations.

Abstract
Candida spp. es un agente etiológico importante en infecciones del tracto urinario, principalmente en población con terapia antimicótica de amplio espectro y con catéteres urinarios. Candida albicans es la especie más frecuente, pero otras especies han surgido como patógenos emergentes. En este trabajo se recolectaron aislamientos de Candida spp. de urocultivos de pacientes que consultaron en Dinamica IPS entre enero 2016 y noviembre 2017. Para estimar la frecuencia de las especies y observar los patrones de sensibilidad, se realizó la identificación fenotípica y su perfil de sensibilidad con el sistema comercial Vitek 2® (BioMérieux, Inc.), adicionalmente se evaluaron mediante análisis de las secuencia y filogenética ITS1-5.8S-ITS2. En el estudio se incluyeron 78 aislamientos de Candida spp. Las frecuencias de especies de Candida identificadas empleando las herramientas moleculares fueron: C. albicans (38,5%), C. tropicalis (23,1%), C. glabrata (21,8%), C. parapsilosis (10,3%), C. metapsilosis y C. krusei (2,5%) y C. guillermondi (1,3%). La identificación por métodos moleculares y por el sistema Vitek 2 fue: C. albicans (93,3%), C. glabrata (94,1 %), C. tropicalis (83,3%), C. parapsilosis (75%) C. guilliermondii y C. krusei (100%). La sensibilidad de todos los aislamientos al fluconazol fue 93,6%.

Abstract
Candiduria is commonly seen in hospitalized patients and most of the patients are asymptomatic, but it may be due to cystitis, pyelonephritis, prostatitis, epididymo-orchitis or disseminated candidiasis. Major risk factors are diabetes mellitus, indwelling urinary catheters, use of broad-spectrum antibiotics, urinary obstruction, and admission to intensive care units. Candida urinary tract infections can be caused by hematogenous spread following candidemia, or retrograde route via the urethra. The presence of Candida species in urine in asymptomatic patients does not warrant antifungal therapy except neutropenic patients, very low-birth-weight infants and patients undergoing urologic procedures. Fluconazole is the treatment of choice for symptomatic infections, it achieves high urinary levels. The other azole antifungals and echinocandins do not reach sufficient urine levels. Amphotericin B deoxycholate is the alternative antifungal agent if fluconazole can not be used because of resistance, allergy or failure.

Abstract
Background Antimicrobial resistance is a widely recognized public health threat, and stewardship interventions to combat this problem are well described. Less is known about antifungal stewardship (AFS) initiatives and their influence within the United States. The purpose of this study was to evaluate evidence on the impact of AFS interventions on clinical and performance measures. Methods A systematic review of English language studies identified in the PubMed and EMBASE databases was performed through November 2017. The review was conducted in accordance with PRISMA. Search terms included antifungal stewardship, antimicrobial stewardship, Candida, candidemia, candiduria, and invasive fungal disease. Eligible studies were those that described an AFS program or intervention occurring in the US and evaluated clinical or performance measures. Results Fifty-four articles were identified and 13 were included. Five studies evaluated AFS interventions and reported clinical outcomes (mortality and length of stay) and performance measures (appropriate antifungal choice and time to therapy). The remaining eight studies evaluated general stewardship interventions and reported data on antifungal consumption. All studies were single center, quasi-experimental with varying interventions across studies. AFS programs had no impact on mortality (3 of 3 studies), with an overall rate of 27% in the intervention group and 23% in the non-intervention group. Length of stay (5 of 5) was also similar between groups (range, 9–25 vs. 11–22). Time to antifungal therapy improved in 2 of 5 studies, and appropriate choice of antifungal increased in 2 of 2 studies. Antifungal consumption was significantly blunted or reduced following stewardship initiation (8 of 8), although a direct comparison between studies was not possible due to a lack of common units. Conclusion The available evidence suggests that AFS interventions can improve performance measures and decrease antifungal consumption. Although this review did not detect improvements in clinical outcomes, significant adverse outcomes were not reported.

Abstract
Introduction The presence of Candida species in urine (candiduria) is a common clinical finding, which may frequently represent colonization or contamination of specimens, however, they may be etiological agents in urinary tract infections (UTIs) or be indicators of underlying pathology in the genitourinary system or disseminated candidaemia. C. albicans is the most frequently isolated species of the genus, however, an increase in the occurrence of non-albicans Candida species (NACS) has been reported, which may be attributable to frequent exposure to fluconazole. Material and methods The aim of this study was to retrospectively assess and compare the prevalence of candiduria and UTIs caused by Candida spp. among inpatients and outpatients at a major clinical center in Hungary, during a 10-year period (2008-2017). Results Candiduria was detected in 0.11-0.75% of positive samples from outpatients, while this number was significantly higher for inpatients, ranging between 3.49-10.63% (p <0.001). Overall, C. albicans was the most frequently isolated species (65.22% in outpatients and 59.64% in inpatients), however, the presence of C. glabrata as a relevant etiologic agent (~20-30%) is also noteworthy, because there are corresponding therapeutic consequences. Conclusions A pronounced female dominance (1.7-2.15-fold), advanced age (~70 years) and hospitalization of affected patients during candiduria is in line with the findings in literature.

Abstract
Candiduria is common in clinical practice. However, an effective and convenient assay to screen for candiduria is still needed. This study aimed to evaluate the performance of the Sysmex UF-1000i urine analyzer for yeast-like cell counting (YLCC) to screen for candiduria prior to urine culture. We retrospectively analyzed data from 5233 urine samples from 1813 patients, including 837 males and 976 females. Urine culture and urinalysis-obtained YLCC data were used to estimate the performance of YLCC in diagnosing candiduria. Different cutoff values were used to calculate sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The YLCC-positive rates differed according to the Candida colony-forming units (CFU) counts in the urine samples. A sharp drop in YLCC-positive rate (from 64.3 to 22.0%) was observed between the urine groups with 104 CFUs and 103 CFUs. A cutoff value of 0 YLCs/μL results in the highest Youden index (0.71) with 77.04% sensitivity and 93.68% specificity. In a group of 34 hospitalized candiduria patients with serial urinalysis data, 25 were YLCC-positive before urine culture. In conclusion, YLCC with the Sysmax UF-1000i could serve as an auxiliary technique to exclude culture-negative specimens prior to urine culture. Positive YLCC results could imply candiduria, especially when persistent YLCC-positive results were observed.

Abstract
OBJECTIVE Candiduria is increasingly frequent in hospitalized debilitated patients. We aimed to evaluate the approach of clinicians to candiduria in the oldest old, and its effect on clearance and mortality. MATERIAL AND METHODS An observational study without intervention was carried out during 2012 and 2013 in three Spanish hospitals over patients with nosocomial candiduria aged 80 and over. Following a diagnostic algorithm, we assessed the appropriateness of antifungal therapy and analyzed the impact of the clinical approach (antifungal therapy, antibiotics discontinuation and catheter removal or replacement) on the outcome (mortality at 60 days and resolution, persistence or recurrence of candiduria). RESULTS Hundred and forty eight patients were included. Symptomatology was attributable to candiduria in 31 instances and 19 asymptomatic patients were found at risk of developing candidemia. In response to culture-results, 77 (52%) of patients were treated with antifungals, mainly fluconazole (97.4%). The use of pharmacological therapy was appropriate (P<0.05) but subtherapeutical doses of fluconazole were widely used and follow-up samples were scarcely submitted. At 60 days of diagnosis the mortality was high (29.7%). The replacement or removal of the catheter resulted in a decrease in mortality and the use of antifungal treatment was associated with recurrence (P<0.05). CONCLUSIONS In the absence of clinical practice guidelines with enough evidence, our study suggests that catheter removal should always be tried in the elderly with candiduria, since it reduces the mortality. The repetition of culture should help to better characterize the asymptomatic episodes, which are predominant, and to reduce the use of antifungals.
