RESUMEN

Introducción: las infecciones por cándida en el ámbito intrahospitalario han ido en ascenso en las últimas décadas en especial en las unidades de cuidado intensivo (UCI), dado el uso cada vez más frecuente de antibióticos de amplio espectro y de procedimientos invasivos tanto diagnósticos como terapéuticos. Hoy se consideran las especies de cándida como la cuarta causa de infección del torrente sanguíneo en los Estados Unidos de Norteamérica, con alto riesgo de complicaciones que incluyen endocarditis, trombosis y embolismo séptico al sistema nervioso central (SNC) entre otros. En relación con la endocarditis por especies de cándida, se ha considerado de mal pronóstico por el alto riesgo de afectación al SNC, por lo que se ha recomendado el manejo quirúrgico como piedra angular de su tratamiento. Presentación del caso: se describe el caso clínico de un paciente con endocarditis y con candidemia por Candida parapsilosis a quien se le realizó manejo médico.


Nosocomial Candida infections have increased in the last decades particularly in the intensive care units (ICU) due to the rise in broad-spectrum antibiotics usage and invasive diagnostic and therapeutic procedures usage. Today, Candida species are recognized as the fourth causative organisms of endovascular infection in the United States of America posing a high risk of endocarditis, thrombosis and septic embolization to the central nervous system (CNS). Endocarditis due to Candida species is associated with a poor prognosis because of the increased risk of CNS involvement for which surgical approach has been recommended as the cornerstone of therapy. We hereby report a patient with endocarditis and candidemia due to Candida parapsilosis, who received medical management.

RESUMEN

Intensive care unit-acquired bloodstream infections (ICU-BSI) are frequent and are associated with high morbidity and mortality rates. We conducted this study to describe the epidemiology and the prognosis of ICU-BSI in our ICU and to search for factors associated with mortality at 28 days. For this, we retrospectively studied ICU-BSI in the ICU of the Cayenne General Hospital, from January 2013 to June 2019. Intensive care unit-acquired bloodstream infections were diagnosed in 9.5% of admissions (10.3 ICU-BSI/1,000 days). The median delay to the first ICU-BSI was 9 days. The ICU-BSI was primitive in 44% of cases and secondary to ventilator-acquired pneumonia in 25% of cases. The main isolated microorganisms were Enterobacteriaceae in 67.7% of patients. They were extended-spectrum beta-lactamase (ESBL) producers in 27.6% of cases. Initial antibiotic therapy was appropriate in 65.1% of cases. Factors independently associated with ESBL-producing Enterobacteriaceae (ESBL-PE) as the causative microorganism of ICU-BSI were ESBL-PE carriage before ICU-BSI (odds ratio [OR]: 7.273; 95% CI: 2.876-18.392; P < 0.000) and prior exposure to fluoroquinolones (OR: 4.327; 95% CI: 1.120-16.728; P = 0.034). The sensitivity of ESBL-PE carriage to predict ESBL-PE as the causative microorganism of ICU-BSI was 64.9% and specificity was 81.2%. Mortality at 28 days was 20.6% in the general population. Factors independently associated with mortality at day 28 from the occurrence of ICU-BSI were traumatic category of admission (OR: 0.346; 95% CI: 0.134-0.894; P = 0.028) and septic shock on the day of ICU-BSI (OR: 3.317; 95% CI: 1.561-7.050; P = 0.002). Mortality rate was independent of the causative organism.

RESUMEN

BACKGROUND: Candidemia or invasive candidiasis (IC) is an increasingly common fungal infection and has been associated with high mortality, particularly among the immunocompromised and critically ill. Although several studies have been conducted to estimate the cost of managing candidemia and IC, quality assessment on the methodological aspects of these cost studies was not performed. To date, no systematic review focusing on the economic burden of candidemia and IC has ever been conducted. OBJECTIVES: The aim of this study was to systematically review the available evidence on the economic burden of candidemia and IC worldwide. METHODS: Databases (ie, PubMed, Scopus, EconLit, HEORO, and Ovid/Embase) were searched through June 2018. Two researchers independently assessed the quality of the eligible studies. Costs reported in the included studies were converted to 2016 USD using Campbell and Cochrane Economics Methods Group-the Evidence for Policy and Practice Information (CCEMG-EPPI)-Centre Cost Converter software. RESULTS: Eight articles were included in this systematic review. The mean total cost per patient with candidemia and IC ranged from $48 487 to $157 574, whereas the mean cost per hospitalization associated with candidemia and IC was from $10 216 to $37 715. All studies were from developed Western countries and reported only direct costs of candidemia and IC. Hospitalization was the main cost driver, contributing to more than half of the total costs. CONCLUSION: Quality cost studies on candidemia and IC based on standardized methods to provide informed decision making among healthcare authorities in implementing appropriate strategies is anticipated, in particular in developing countries.

RESUMEN

Infections with Candida spp. cause significant morbidity and mortality despite intensive treatment with antifungal agents. Novel treatment options are urgently needed. Predominately immunocompromised patients are affected. This warrants the conclusion that strengthening host immunity may have the potential to improve outcome. Recent studies imply a potential benefit of checkpoint inhibition reversing hyporesponsiveness of innate and adaptive immunity during invasive fungal infections and invasive candidiasis in particular. We here give a brief overview of first preclinical data in vitro and in vivo and clinical evidence in selected cases.

RESUMEN

OBJECTIVE: To investigate the etiological and clinical characteristics of immunocompetent patients with candidemia. METHODS: The clinical and microbiological data of patients diagnosed as candidemia admitted in Peking University Third Hospital from January 2010 to June 2016 were retrospectively analyzed. Underlying diseases, Candida spp. colonization, clinical manifestations, microbiological data, treatment and the outcome were compared between the HIV-negative immunocompromised (IC) and nonimmunocompromised (NIC) patients. RESULTS: A total of 62 cases diagnosed as candidemia were analyzed including 36 men and 26 women, with 16 to 100 years of age [(66.02±17.65) years]. There were 30 NIC and 32 HIV-negative IC patients respectively. In the NIC patients, there were 19 cases (19/30, 63.33%) with admission in intensive care unit (ICU), 21 (21/30, 70.00%) associated diabetes mellitus or uncontrolled hyperglycemia and 22 (22/30,73.33%) receiving invasive mechanical ventilation, while in the HIV-negative IC patients, there were 8 (8/32, 25.00%), 13 (13/32, 40.63%) and 7 (7/32, 21.88%) respectively (P<0.05). The NIC patients had higher acute physiology and chronic health evaluation (APACHE II) scores and sequential organ failure assessment (SOFA) scores both at admission (19.98±5.81, 6.04±6.14) and candidemia onset (25.61±6.52, 12.75±8.42) than the HIV-negative IC patients (APACHEII 15.09±5.82, 22.15±5.98) and SOFA 2.87±2.73, 7.66±5.64 respectively (P<0.05). In the NIC patients, twenty-one cases (21/30, 70.00%) died in hospital, while 14 cases (14/32, 43.75%) in HIV-negative IC. The crude mortality was significantly different between the two groups (P<0.05). By blood culture, Canidia albicans remained the the most prevalent isolates in all the patients. Clinical manifestation, Candida spp. colonization, etiology and drug susceptibility were also similar between NIC and HIV-negative IC patients (P>0.05). CONCLUSION: Candidemia in NIC patients tends to occur in those who are much more critically ill, more often admitted in ICU, and more frequently have diabetes mellitus or uncontrolled hyperglycemia and receive invasive mechanical ventilation than HIV-negative IC patients. NIC patients also have poorer prognosis than HIV-negative IC patients. Clinical manifestations, and microbiological characteristics are similar between HIV-negative IC and NIC patients.

RESUMEN

PURPOSE OF REVIEW: Invasive fungal disease (IFD) is a cause of morbidity and mortality in allogeneic hematopoietic stem cell transplant (HSCT) recipients. As more potent broad-spectrum antifungal agents are used in prophylaxis, drug resistance and less common fungal species have increased in frequency. Here we review current treatments available for IFD and examine the potential for adoptive T-cell treatment to enhance current therapeutic choices in IFD. RECENT FINDINGS: There is growing evidence supporting the role of T cells as well as phagocytes in antifungal immunity. T cells recognizing specific antigens expressed on fungal morphotypes have been identified and the role of T-cell transfer has been explored in animal models. The clinical efficacy of adoptive transfer of antigen-specific T cells for prophylaxis and treatment of viral infections post-HSCT has raised interest in developing good manufacturing practice (GMP)-compliant methods for manufacturing and testing fungus-specific T cells after HSCT. SUMMARY: As the outcomes of IFD post-HSCT are poor, reconstitution of antifungal immunity offers a way to correct the underlying deficiency that has caused the infection rather than simply pharmacologically suppress fungal growth. The clinical development of fungus specific T cells is in its early stages and clinical trials are needed in order to evaluate safety and efficacy.

RESUMEN

INTRODUCTION: Candidaemia, recognised as a fairly common disease among intensive care unit (ICU) patients, carries a poor prognosis. However, as studies on the prognostic factors associated with candidaemia in ICU patients are limited, this study aimed to establish the best prognostic factor for ICU patients with candidaemia in a tertiary care hospital in Japan. METHODS: We conducted a retrospective cohort study of patients with candidaemia in the emergency ICU at Fukuoka University Hospital, Fukuoka, Japan, from April 2010 to March 2015. Demographic and clinical data was collected from the patients' medical records and laboratory databases. RESULTS: A total of 25 patients were included in the study. However, 18 patients died during hospitalisation, resulting in an in-hospital mortality rate of 72.0%. The variables of Sequential Organ Failure Assessment (SOFA) score and cumulative number of risk factors for invasive candidiasis showed significant differences between patients in the survivor and non-survivor groups (p < 0.05). The areas under the receiver operating characteristic curves for the SOFA score and cumulative number of risk factors for invasive candidiasis were 0.873 (95% confidence interval [CI] 0.72-1.00) and 0.937 (95% CI 0.84-1.00), respectively. CONCLUSION: Our results suggest that the cumulative number of risk factors for invasive candidiasis was the most useful prognostic indicator for candidaemia in ICU patients.

RESUMEN

AIM: to identify the risk factors of candidemia and to develop a scoring system that could be implemented in Cipto Mangunkusumo Hospital (RSCM), Jakarta, Indonesia. METHODS: this study was a retrospective study with case control design using the medical records of patients since 2011 to 2014. All sepsis patients hospitalized in the RSCM with a positive blood culture for Candida were included in this study as a case group. The control group was all of the sepsis patients without candidemia. The ratio for case and control groups was equal (1:1). RESULTS: from 234 patients who were analyzed, the risk factors that influenced the study were length of stay of 8-14 days (OR 3.464; 95% CI 1.458-7.800), length of stay of more than 14 days (OR 6.844; 95% CI 3.0-15.330), severe sepsis (OR 16.407; 95% CI 1.458-7.800), and surgery (OR 3.03; 95% CI 1.492-6.152). The predictors for candidemia in RSCM were length of stay in hospital for 8-14 days (score 1), a length of stay ≥14 days (score 2), severe sepsis (score 3), and surgery (score 1), with a cut off score of 3.5. CONCLUSION: the results of this study have indicated that a scoring system in order to guide an empirical treatment for candidemia can be developed by using the risk factors for candidemia from patients who have been identified as patients with risk at Cipto Mangunkusumo Hospital.

RESUMEN

Candida bloodstream infections (BSI) are associated with significant morbidity, mortality, and increased health care costs. Early treatment is essential, because delayed therapy detrimentally impacts clinical outcomes. The FDA recently approved the first culture-independent direct molecular detection method for Candida BSIs (T2Candida). The speed and sensitivity of this assay give it the potential to improve patient care, but the reagents and instrumentation are expensive. We used an analytic decision tree model to compare the cost-effectiveness of T2Candida-directed antifungal therapy (T2DT) to that of either empirical therapy (ET) or blood culture-directed therapy (BCDT). The costs included those of T2Candida testing, antifungal treatment, and hospital length of stay. The effectiveness measure was survival status at hospital discharge. T2DT was less costly and more effective than BCDT but was less costly and less effective than ET with an echinocandin (incremental cost-effectiveness ratio, $111,084 per additional survivor). One-way sensitivity analyses demonstrated that the cost-effectiveness of T2DT was highly dependent on Candida BSI prevalence and the cost of antifungal therapy and T2Candida test reagents. The use of T2DT reduced the number of unnecessarily treated patients by 98% relative to that with ET. Reduced drug exposure might lessen the possibility of drug-related adverse events and may also prevent the development of antifungal resistance or emergence of drug-resistant Candida species. The greatest benefit of T2Candida appears to be the ability to confidently withhold or stop empirical antifungal therapy in low-to-moderate-risk patients who are unlikely to benefit from treatment.

RESUMEN

INTRODUCTION: Candida bezoar (CB) is a rare finding in neonates and infants with candiduria, presenting as necrotic debris with proliferating mycelia in the collecting system of the kidney. If initial antifungal medical treatment does not result in clearance of candiduria and disappearance of CB on ultrasound in dilated kidneys, invasive interventions like insertion of nephrostomy tubes (NT) or surgical interventions to drain the kidney are sometimes advocated(.). However, NT placement can be a technical challenge, especially in pre- and dysmature neonates, and NT displacement or obstruction by the CB can lead to suboptimal treatment. Identification of those children who will benefit from invasive renal drainage is important. OBJECTIVE: This study evaluates the management of patients with CB in three tertiary referral hospitals to determine criteria for intervention. MATERIALS AND METHODS: A retrospective multicenter chart analysis was conducted of children with candiduria and ultrasonographic demonstration of CB (diagnosed between March 1995 and August 2012). The indication for invasive renal drainage (if performed) and subsequent clinical outcome, serum creatinine levels and ultrasound findings were assessed. RESULTS: A total of 12 children were included, two of which were premature neonates. Eight children had congenital urogenital anomalies. One older child with acute myeloid leukemia had CB during chemotherapy and one ex-premature developed CB following cerebral candidiasis. All children received systemic antifungal medication; in seven children invasive treatment was added. Indications for invasive treatment were clinical deterioration, progressive renal dilation, pyonephrosis, rising creatinine levels and persistence of CB. Two underwent a Y-cutaneous ureterostomy and nephrostomy tubes were inserted in five children. Percutaneous renal drainage by nephrostomy led to complications in 3 of 6 procedures. In all patients, irrespective of therapeutic modality, follow-up ultrasound demonstrated no de novo changes. No additional parenchymal defects or deterioration of split renal function were seen on DMSA or MAG-3 scan. DISCUSSION: In the literature renal drainage is suggested in case of complete obstruction. However dilatation is a frequent finding in children as part of the congenital renal anomaly and does not necessarily mean that there is obstruction of the urinary tract. Even in children without candida infections the diagnosis of obstruction is not straightforward, while the results of a MAG 3 scan can be obscured by compromised kidney function, parenchymal bacterial infiltration and neonatal immaturity of the kidney. If candiduria and CB persist despite intensive medical treatment, intensive consultation is required before renal drainage, because NT insertion might be a surgical challenge. Complications such as displacement of the NT, urinoma development, or NT obstruction can occur and was seen in three of six procedures. Premature neonates seem to be more prone to complications due to their small anatomical proportions, requiring medical equipment with small diameters prone to displacement and obstruction. Some studies describe successful pharmaceutical management in the majority of patients with CB. Other studies describe unilateral surgical intervention in children with bilateral CB where unilateral drainage did not influence overall renal outcome. This is in line with our results. A limitation of the present study is its retrospective design. In this population, the motivation for invasive renal drainage or conservative management was not well documented in all cases, and was mainly based on clinical and diagnostic parameters like creatinine levels and radiographic findings. CONCLUSION: Renal drainage should be considered in selected cases after failure of systemic antifungal treatment. Inserting and maintaining a nephrostomy tube in young children is associated with a high rate of complications; conservative treatment is likely to be sufficient in the majority of patients with candiduria and CB.

RESUMEN

OBJECTIVE: To identify risk factors and mycological characteristics of candidemia in Pediatric ICU of a tertiary-care hospital. METHODS: Patients were screened for candidemia by blood culture. Recovered isolates were speciated and subjected to antifungal susceptibility testing. For every candidemic patient, three controls were matched for age, underlying diagnosis and period of hospitalization. Premature neonates were also matched for birth-weight. Proportion of cases and controls on specific antibiotics or indwelling devices was compared using Chi-square test, while unpaired t-test was used for comparing the number of antibiotics used and the number of days of antibiotic administration. Concordance between susceptibility testing methods was evaluated using Chi-square test. RESULTS: Significantly wider spectrum of antibiotic coverage was observed among the 28 candidemic patients. While every patient received antibiotic against enteric gram-negative bacilli, antibiotic usage for additional groups of microorganisms was significantly higher among cases. Association of candidemia with increasing use of indwelling devices was also observed. Endogenous colonization was higher in candidemic infants. Candida albicans was the commonest species (n = 18), followed by C. tropicalis (n = 7). Fluconazole and ketoconazole resistance was observed in 10.7 % cases. CONCLUSIONS: This information on pediatric candidemia could be used to devise locally-tailored strategies for identifying at-risk patients, underline the importance of routine antifungal susceptibility testing and formulate appropriate guidelines for management.

RESUMEN

Use of totally implantable venous-access ports (TIVAPs) is standard practice for patients with diseases such as solid-tumour cancers, haematological malignancies, and chronic digestive diseases. Use of TIVAPs allows long-term administration of venotoxic compounds, improves patients' quality of life, and reduces the risk of infection. Microbial contamination, formation of pathogenic biofilms, and infection, however, are associated with morbidity, mortality, and increased health-care costs. Local and systemic complications or infections related to specific pathogens might lead to device removal. Alternatively, conservative treatment with combined systemic antibiotics and antibiotic lock therapy might be useful. We discuss in-vitro and in-vivo basic and clinical research findings on the epidemiology, diagnosis, and prevention of TIVAP-related infections, the current challenges to management, promising strategies, and some treatments in development that are likely to improve outcomes of TIVAP-related infections, with a particular focus on antibiotic lock therapy.

RESUMEN

The incidence of candidemia and invasive Candida infections has increased substantially over the last 2 decades. These infections are associated with risk factors that characterize intensive care unit patients. Candidemia and invasive Candida are highly morbid and associated with significantly increased mortality. Outcomes in the intensive care setting depend on physician awareness and rapid intervention. The epidemiology of the disease, its diagnostic challenges, and management strategies, including prophylactic, preemptive, and definitive therapeutic approaches, are presented herein.

RESUMEN

Endogenous endophthalmitis is a rare but potentially blinding complication of neonatal sepsis. Early diagnosis and aggressive treatment are essential to avoid vision loss. Therapeutic options include systemic and intravitreal antibiotics, as well as vitrectomy in selected cases. We report a series of 6 premature very low birth weight neonates who developed endogenous endophthalmitis in our NICU over the past 3 years. Endophthalmitis was part of early-onset sepsis in 2 newborns, both of whom died, and late-onset sepsis in 4 newborns, of which 1 infant died. None of the neonates had any history of previous trauma or intervention to the eye. Maternal screening for congenital infections, including HIV, was negative in all. Causative organisms included Klebsiella pneumoniae (2 cases), Pseudomonas aeruginosa (2 cases), Methicillin-resistant Staphylococcus aureus (1 case), and Candida albicans (1 case). All bacterial isolates showed resistance to first-line antibiotics. Of the 3 survivors, 2 infants had normal vision in the affected eye, and 1 developed phthisis bulbi after corneal perforation and required enucleation. This report draws attention to the emergence of endophthalmitis as a complication of neonatal sepsis in places where, although survival of very low birth weight newborns has increased significantly due to improved care, the burden of infection continues to be high. We emphasize the importance of daily examination of eyes as a part of routine clinical care in septic newborns for early diagnosis of endophthalmitis and prompt intervention in consultation with an ophthalmologist to optimize the outcome.

RESUMEN

STUDY OBJECTIVE: To analyze the impact of a comprehensive care bundle directed by an antimicrobial stewardship team (AST) on the management of candidemia. DESIGN: Single-center, quasi-experimental study. SETTING: A 930-bed academic hospital. PATIENTS: Seventy-eight patients with candidemia were evaluated; 41 patients received the candidemia care bundle (AST group), and 37 did not (historical control group). MEASUREMENTS AND MAIN RESULTS: A candidemia care bundle was developed by an interdisciplinary AST, incorporating key elements from the Infectious Diseases Society of America's Clinical Practice Guidelines for the Management of Candidemia. The AST made prospective recommendations in accordance with the care bundle. Bundle elements were utilization of appropriate antifungal agents with appropriate duration of use, removal of intravenous catheters, repeat blood cultures, monitoring of time until clearance of candidemia, and performance of ophthalmologic examinations. Compliance with all candidemia care bundle elements was significantly higher in the AST group versus the control group (78.0% vs 40.5%, p=0.0016). Implementation of the care bundle significantly improved rates of ophthalmologic examination (97.6% vs 75.7%, p=0.0108), selection of appropriate antifungal therapy (100% vs 86.5%, p=0.0488), and compliance with an appropriate duration of therapy (97.6% vs 67.7%, p=0.0012). In addition, the AST group had fewer excess total days of therapy beyond the recommended duration than the control group (5 vs 83 total antifungal days). Length of hospitalization (20 vs 21 days, p=0.9184), time until clearance of candidemia (3 vs 3 days p=0.610), rate of persistent candidemia (22% vs 40.5%, p=0.126), and rate of recurrent candidemia (4.9% vs 5.4%, p=0.916) were similar in the AST group versus the control group. CONCLUSION: A comprehensive candidemia care bundle directed by our institution's AST improved the management of patients with candidemia. We encourage further exploration into the use of care bundles by ASTs as part of their multifaceted approach to promoting appropriate antimicrobial utilization and optimizing the management of patients with infectious diseases.

RESUMEN

Infections caused by Candida dubliniensis in humans are rare and have never been reported in Taiwan. We report two cancer patients with catheter-related fungemia due to C. dubliniensis infection in Taiwan. The two isolates were confirmed to the species level using an oligonucleotide array system and sequence analysis, and both showed high in vitro susceptibilities to nine antifungal agents. The catheters were removed, and both patients responded well to antifungal treatment. Although this type of infection is rare, physicians should consider C. dubliniensis as one of the possible pathogens causing catheter-related infections in Taiwan.

RESUMEN

This study investigated the impact of management of a totally implantable central venous access port device, Port-A-Cath (Smith Medical, St. Paul, MN, USA), on the outcome of 98 cancer patients with candidaemia. Port-A-Cath retention was found to be significantly associated with poorer outcome, independent of other significant adverse factors [breakthrough candidaemia, Acute Physiology and Chronic Health Evaluation (APACHE) II score ≥ 21, and worse Eastern Cooperative Oncology Group (ECOG) performance score (3-4)]. However, retention of Port-A-Cath devices could be considered in patients who do not have definite catheter-related candidaemia, are not using total parenteral nutrition, do not have poor ECOG performance scores or APACHE II scores, and do not have septic shock.

RESUMEN

Finding the source of a fungal infection and selecting the most appropriate treatment for candidemia is often challenging for physicians, especially when the patient has a complex medical history. We describe the case of a 48-year-old woman who had persistent candidemia after undergoing explantation of a left ventricular assist device. The source of the infection was found to be a right atrial thrombus. The mass was removed, and the patient underwent aggressive treatment with micafungin. Removal of the right atrial mass, followed by potent antifungal treatment, resulted in a successful recovery.

RESUMEN

Candida sake infections are rare, but have been shown to cause severe infections including fungal endocarditis, peritonitis and bloodstream infection. As the reported incidence of C. sake candidaemia is very low, there is a dearth of data regarding the associated risk factors, antifungal agent-susceptibility patterns, optimal treatment policies, clinical course and outcomes of patients with such infections. We report a series of seven non-neutropenic intensive care unit patients with C. sake candidaemia. Most of the patients were men (6/7), were over 65 years of age (5/7) and had a history of recent hospitalisation (4/7) and comorbidities (4/7). However, all seven patients had a previous history of antibiotic uptake for more than 5 days and had a central venous catheter in situ at the time of taking specimens for culture. In four patients, infection was azole-resistant. Four patients required vasopressor support, three required mechanical ventilation and two required renal replacement therapy. Three of the seven patients died. This case series emphasises the importance of performing species identification and antifungal susceptibility testing in ICU patients with candidaemia, especially those with advanced age, underlying chronic diseases, indwelling vascular catheters, or a history of previous antibiotics or recent hospitalisations, as these patients may be at an increased risk of developing rare Candida infections like C. sake. Moreover, these rare Candida species may be more frequently resistant to azole antifungal agents, and may be associated with significant mortality.
