[Invasive candidiasis after hematopoietic cell transplantation].

Candida species are the second most frequent fungal pathogen of invasive fungal disease after hematopoietic cell transplantation (HCT) following Aspergillus species. Prolonged severe neutropenia and mucocutaneous barrier impairment resulting from the conditioning regimen or central venous catheter placement are major risk factors for invasive candidiasis in the early phase after HCT. Graft-versus-host disease (GVHD) and corticosteroid use affect the development of invasive candidiasis in the post-engraftment phase after allogeneic HCT. Breakthrough candidemia mainly caused by non-albicans Candida species still occurs and is associated with a high mortality rate although antifungal prophylaxis that covers Candida species is a standard of care in HCT. A multidisciplinary approach is required to treat patients with candidiasis, involving multiple healthcare professionals from different fields, such as transplant physicians, infectious disease specialists, ophthalmologists, nurses, pharmacologists, and laboratory technicians. This review focuses on the epidemiology, risk factors, antifungal prophylaxis, diagnosis, and treatment of invasive candidiasis after HCT. Additionally, the association between Candida species and GVHD in allogeneic HCT is discussed.

Risk Factors for Invasive Candida Infection in Critically Ill Patients: A Systematic Review and Meta-analysis.

BACKGROUND: Current guidelines recommend empirical antifungal therapy in patients with sepsis with high risk of invasive Candida infection. However, many different risk factors have been derived from multiple studies. These risk factors lack specificity, and broad application would render most ICU patients eligible for empirical antifungal therapy. RESEARCH QUESTION: What risk factors for invasive Candida infection can be identified by a systematic review and meta-analysis? STUDY DESIGN AND METHODS: We searched PubMed, Web of Science, ScienceDirect, Biomed Central, and Cochrane and extracted the raw and adjusted OR for each risk factor associated with invasive Candida infection. We calculated pooled ORs for risk factors present in more than one study. RESULTS: We included 34 studies in our meta-analysis resulting in the assessment of 29 possible risk factors. Risk factors for invasive Candida infection included demographic factors, comorbid conditions, and medical interventions. Although demographic factors do not play a role for the development of invasive Candida infection, comorbid conditions (eg, HIV, Candida colonization) and medical interventions have a significant impact. The risk factors associated with the highest risk for invasive Candida infection were broad-spectrum antibiotics (OR, 5.6; 95% CI, 3.6-8.8), blood transfusion (OR, 4.9; 95% CI, 1.5-16.3), Candida colonization (OR, 4.7; 95% CI, 1.6-14.3), central venous catheter (OR, 4.7; 95% CI, 2.7-8.1), and total parenteral nutrition (OR, 4.6; 95% CI, 3.3-6.3). However, dependence between the various risk factors is probably high. INTERPRETATION: Our systematic review and meta-analysis identified patient- and treatment-related factors that were associated with the risk for the development of invasive Candida infection in the ICU. Most of the factors identified were either related to medical interventions during intensive care or to comorbid conditions.

Risk factors for the development of esophageal candidiasis among patients in community hospital.

The aim of this study was to clarify risk factors for esophageal candidiasis (EC) in immunocompetent patients in a community hospital. 7736 patients who underwent esophagogastroduodenoscopy at our hospital from April 2012 to July 2018 were enrolled. The relationships between EC and the following factors: age, gender, body mass index, lifestyle, lifestyle-related diseases, medication, and endoscopic findings were analyzed. EC was observed in 184 of 7736 cases (2.4% morbidity rate). Multivariate analysis revealed that significant risk factors for the development of EC were: diabetes mellitus {odds ratio (OR): 1.52}, proton pump inhibitor (PPI) use (OR: 1.69), atrophic gastritis (AG) (OR: 1.60), advanced gastric cancer (OR: 4.66), and gastrectomy (OR: 2.32). When severe EC (Kodsi grade ≥ II) was compared to mild EC (grade I), the most significant risk factors were advanced gastric cancer (OR: 17.6) and gastrectomy (OR: 23.4). When considering the risk of AG and PPI use with EC development, the risk increased as follows: AG (OR: 1.59), PPI use (OR: 2.25), and both (OR: 3.13). PPI use, AG, advanced gastric cancer and post-gastrectomy are critical risk factors for the development of EC. We suggest close monitoring for EC development when PPIs are administered to patients with these factors.

Molecular genotyping of Candida albicans isolated from different sites may trace the etiological infection routes: Observation in China.

BACKGROUND: Invasive candidiasis is a growing concern worldwide, especially in immunocompromised patients, including ICU patients. OBJECTIVES: As Candida albicans is the leading cause of candidaemia, it is important to investigate the evolution of C. albicans in patients with candidaemia. METHODS: We analysed 238 strains of C. albicans isolated from different body sites. Antifungal susceptibility testing, CAI loci genotyping and multilocus sequence typing (MLST) of all isolates were performed. The relationships among the total isolates that differed in sequence at only one of the seven housekeeping gene loci were analysed using eBURST. RESULTS: Multilocus sequence typing analysis in 238 isolates by combining seven housekeeping alleles revealed 175 diploid sequence types, in which 84 were newly identified. eBURST analysis for these data recognised 19 clonal complexes (CCs) and 79 singletons. Besides, seventy-three CAI genotypes were identified. Blood isolates showed maximum genotypes (49), and the dominant genotypes were CAI 17-21 and CAI 21-21. Oral isolates possessed 25 CAI genotypes, and the dominant genotypes were CAI 17-21 and CAI 21-21 as well. Since isolates with CAI allele numbers <30 showed easier transmission, CAI 17-21 and CAI 21-21 were the most frequently transmitted. Finally, the CAI genotypes were classified into six groups. CONCLUSIONS: This work revealed the oral and blood strains isolated from the patients with candidaemia in ICU shared the identical dominant CAI genotypes. Our data expanded the C. albicans MLST database and helped with understanding the evolution and spread of invasive candidiasis.

Chronic Disseminated Candidiasis During Hematological Malignancies: An Immune Reconstitution Inflammatory Syndrome With Expansion of Pathogen-Specific T Helper Type 1 Cells.

BACKGROUND: Chronic disseminated candidiasis (CDC) is a rare disease that mostly occurs after chemotherapy-induced prolonged neutropenia in patients with hematological malignancies. It is believed to ensue from Candida colonization, breach of the intestinal epithelial barrier, and venous translocation to organs. Fungal blood or liver biopsy cultures are generally negative, suggesting the absence of an ongoing invasive fungal disease. METHODS: To unravel the contribution of the immune system to CDC pathogenesis, we undertook a prospective multicentric exploratory study in 44 CDC patients at diagnosis and 44 matched controls. RESULTS: Analysis of Candida-specific T-cell responses using enzyme-linked immunospot assays revealed higher numbers of interferon (IFN)γ-producing T cells reactive to mp65 or candidin in 27 CDC cases compared with 33 controls. Increased plasma levels of soluble CD25, interleukin (IL)-6, IL-1ß, tumor necrosis factor-α, and IL-10 and lower levels of IL-2 were observed in CDC patients versus controls. Neutrophilia and higher levels of CD4 and CD8 T-cell activation were found in CDC patients as well as increased proportions of CXCR3-expressing TCRγδ +Vδ2+ cells. CONCLUSIONS: The expansion of Candida-specific IFNγ-producing T cells together with features of T-cell activation and systemic inflammation identified here support the view that CDC belongs to the broad spectrum of fungal-associated immune reconstitution inflammatory syndromes.

Fungal Infections of the Stem Cell Transplant Recipient and Hematologic Malignancy Patients.

Despite advances in chemotherapy and supportive care, morbidity and mortality remain high for patients with hematologic malignancies (HMs). Those who require hematopoietic stem cell transplantation (HSCT) often require significant immunosuppression and are subject to a variety of complications. These patients carry multiple risk factors for infectious complications, including the development of invasive fungal infections, compared with the general population. Because antifungal prophylaxis has been widely adopted, there has been a shift away from invasive candidiasis toward invasive mold infections, including breakthrough infections. For patients with HM and HSCT, we outline the epidemiology, manifestations, diagnosis, and treatment of invasive fungal infections.

Impact of Antimicrobial Prophylaxis for Severe Acute Pancreatitis on the Development of Invasive Candidiasis: A Large Retrospective Multicenter Cohort Study.

OBJECTIVE: Antimicrobial prophylaxis is not generally recommended for patients with severe acute pancreatitis (SAP) owing to the limited clinical benefits. Nonetheless, it is frequently administered in actual practice given the patients' critical condition and the lack of solid evidence showing adverse effects of antimicrobial prophylaxis. We evaluated herein an association between antimicrobial prophylaxis and invasive pancreatic candidiasis as an adverse effect in patients with SAP. METHODS: This is a retrospective cohort study of all consecutive patients with SAP who were admitted to the study institutions (n = 44) between January 1, 2009, and December 31, 2013. We performed multivariable logistic regression analysis adjusting for the extent of pancreatic necrosis and surgical interventions for invasive pancreatic candidiasis. RESULTS: Of the 1097 patients with SAP, 850 (77.5%) received antimicrobial prophylaxis, and 21 (1.9%) had invasive pancreatic candidiasis. In multivariable logistic regression analysis, antimicrobial prophylaxis was significantly associated with the development of invasive pancreatic candidiasis (adjusted odds ratio, 4.23; 95% confidence interval, 1.14-27.6) (P = 0.029). CONCLUSIONS: The results suggest that antimicrobial prophylaxis may contribute to the development of invasive pancreatic candidiasis, and therefore, the routine use of antimicrobial prophylaxis for SAP may be discouraged.

Fungal endocarditis after transcatheter aortic valve replacement (TAVR): Case report and review of literature.

The reported number of transcatheter aortic valve replacement-associated infective endocarditis (TAVR-IE) cases has been increasing worldwide, but information about the incidence and clinical features of fungal TAVR-IE is quite limited. We present a patient who acquired TAVR-IE caused by Candida parapsilosis four month after TAVR, who was successfully treated redo-aortic valve replacement and prolonged antifungal therapy.

Comparison of the incidence, clinical features and outcomes of invasive candidiasis in children and neonates.

BACKGROUND: Invasive candidiasis differs greatly between children and neonates. We aimed to investigate the different therapeutic approaches and their effects on treatment outcomes of these two groups. METHODS: Episodes of neonatal invasive candidiasis were compared with non-neonatal pediatric episodes during a 12-year cohort study. Clinical isolates were documented by matrix-assisted laser desorption/ionization-time of flight mass spectrometry and DNA sequencing, and antifungal susceptibility testing was performed. RESULTS: A total of 342 episodes of invasive candidiasis (113 neonatal and 229 non-neonatal pediatric episodes) in 281 pediatric patients (96 neonates and 185 children) were identified. Candida albicans was the most common pathogen causing invasive candidiasis in neonates and children (47.8% vs. 44.1%). The antifungal susceptibility profiles were not significantly different between neonates and children. More neonates received amphotericin B as therapy, whereas more children received fluconazole or caspofungin. Compared with children, neonates had a significantly longer duration of fungemia, higher rates of septic shock (34.5% vs. 21.8%; P = 0.013), sepsis-attributable mortality (28.3% vs. 17.5%; P = 0.024) and in-hospital mortality (42.7% vs. 25.4%; P = 0.004) than children. Independent risk factors for treatment failure of invasive candidiasis were septic shock (odds ration [OR] 16.01; 95% confidence interval [CI] 7.64-33.56; P <  0.001), delayed removal of intravenous catheter (OR 6.78; 95% CI 2.80-17.41; P <  0.001), renal failure (OR 5.38; 95% CI 1.99-14.57; P = 0.001), and breakthrough invasive candidiasis (OR 2.99; 95% CI 1.04-8.67; P = 0.043). CONCLUSIONS: Neonatal invasive candidiasis has worse outcomes than non-neonatal pediatric candidiasis. Neonatologists and pediatricians must consider age-specific differences when developing treatment and prevention guidelines, or when interpreting studies of other age groups.

Invasive Candida Infection after Upper Gastrointestinal Tract Surgery for Gastric Cancer.

Upper gastrointestinal tract (GIT) surgical procedures are more likely to cause nosocomial Candida peritonitis than lower GIT procedures and they thus constitute an independent risk factor for mortality. Because of the severity of postsurgical fungal infections complications, intensivists and surgeons need to be extremely aware of their clinical importance in critically ill postsurgical intensive care unit (ICU) patients. We analyzed the clinical and microbiological data of 149 oncologic patients who were hospitalized in the ICU at Soroka Medical Center between January 2010 and January 2015 after undergoing upper GIT surgery for gastric cancer. Invasive fungal infections related to secondary peritonitis following oncologic upper GIT surgery had a higher mortality rate than patients with nonfungal postoperative infectious complications. The presence of gastroesophageal junction leakage and advanced age were found to be independent risk factors for invasive fungal infection after oncologic upper GIT surgery.

Incidencia y etiología de la candidiasis invasiva en la Unidad de Cuidados Intensivos de Niños del Centro Hospitalario Pereira Rossell / Incidence and etiology of invasive candidiasis in the Pediatric Intensive Care Unit of of the Pereira Rossell Hospital Center

Introducción: en los últimos años ha aumentado la incidencia de candidiasis invasiva (CI) a nivel mundial. En nuestro país no se disponen de estudios epidemiológicos sobre CI. El objetivo fue determinar incidencia de CI en la Unidad de Cuidados Intensivos de Niños del Centro Hospitalario Pereira Rossell. Metodología: estudio descriptivo retrospectivo. Se incluyeron los niños con CI hospitalizados entre 1/1/2009-1/6/2014. A partir de los cultivos micológicos se identificaron las historias clínicas de los pacientes que desarrollaron CI. Se definió CI al aislamiento de Candida en algún sitio estéril. Se calcularon la densidad de incidencia y de prevalencia. Se registró motivo de ingreso y presencia de factores de riesgo para CI. Resultados: se identificaron 6 casos de CI, incidencia de 1,86 c/1000 ingresos. Los aislamientos se realizaron en hemocultivos (n=3) y líquido peritoneal (n=3). Las especies de Candida aisladas fueron C. albicans (n=3), C. parapsilosis (n=2) y C. tropicalis (n=1). Los factores de riesgo para CI presentes fueron dispositivos invasivos (n=6), antibióticos de amplio espectro (n=6), alimentación parenteral (n=5), cirugía abdominal(n=4). Todos los aislamientos fueron sensibles a los azoles. En 1 de las 6 CI se inició tratamiento empírico previo al aislamiento. Fallecieron 4 de los 6 pacientes. Discusión: la incidencia fue similar a otra experiencia realizada en cuidados intensivos pediátricos. Los pacientes que desarrollaron CI presentaron asociación de factores de riesgo. Los aislamientos fueron sensibles a fluconazol. Caracterizar a estos niños permitirá iniciar en forma oportuna el tratamiento antifúngico. Se destaca la importancia de desarrollar la vigilancia continua sobre las especies de Candida y su patrón de sensibilidad a los antifúngicos.

Introduction: invasive infections by Candida strains have increased around the world in the last years. There are no epidemiological studies on invasive candidiasis (IC) in Uruguay. The study aimed to find out the incidence of IC in the Pediatric Intensive Care Unit (PICU) at the Pereira Rossell Hospital Center (CHPR). Method: a retrospective and descriptive study was conducted. Children hospitalized in PICU of the CHPR between 1/1/2009 and 1/6/2014 were included in the study. The medical records of patients who developed IC were identified based on mycological cultures. Invasive candidiasis was defined as the isolation of the fungus in a sterile site. Incidence and prevalence density were calculated. Cause for hospitalization and risk factors for IC were recorded. Results: six cases of IC were identified and the incidence was of 1.86/1000 hospitalized children in PICU. Isolation of Candida was done in blood cultures (n=3) and peritoneal fluid (n=3). The species of Candida isolated were C. albicans (n=3), C.parapsilosis (n=2) and C. tropicalis (n=1). Risk factors for IC were identified in the 6 cases. Use of invasive prosthesis and a wide spectrum antibiotics were identified in the 6 cases, as well as parenteral nutrition (n=5) and abdominal surgery (n=4). All isolations of Candida were sensitive to fluconazole. Antifungal empiric treatment was started in one case prior to the isolation of Candida. Four out of six children died. Discussion: the incidence of IC found was similar to that in another study in a PICU. Children who developed IC presented several risk factors for IC. The 6 isolations of Candida were sensitive to fluconazole. Analyzing the clinical features of these children will allow the identification of patients with high risk of IC and to timely initiate antifungal treatment. It is necessary to maintain a continuous surveillance on Candida species and their sensitivity pattern to antifungal medication.

Early-Onset Invasive Candidiasis in Extremely Low Birth Weight Infants: Perinatal Acquisition Predicts Poor Outcome.

BACKGROUND: Neonatal invasive candidiasis (IC) presenting in the first week of life is less common and less well described than later-onset IC. Risk factors, clinical features, and disease outcomes have not been studied in early-onset disease (EOD, ≤7 days) or compared to late-onset disease (LOD, >7 days). METHODS: All extremely low birth weight (ELBW, <1000 g) cases with IC and controls from a multicenter study of neonatal candidiasis enrolled from 2001 to 2003 were included in this study. Factors associated with occurrence and outcome of EOD in ELBW infants were determined. RESULTS: Forty-five ELBW infants and their 84 matched controls were included. Fourteen (31%) ELBW infants had EOD. Birth weight <750 g, gestation <25 weeks, chorioamnionitis, and vaginal delivery were all strongly associated with EOD. Infection with Candida albicans, disseminated disease, pneumonia, and cardiovascular disease were significantly more common in EOD than in LOD. The EOD case fatality rate (71%) was higher than in LOD (32%) or controls (15%) (P = .0001). The rate of neurodevelopmental impairment and mortality combined was similar in EOD (86%) and LOD (72%), but higher than in controls (32%; P = .007). CONCLUSIONS: ELBW infants with EOD have a very poor prognosis compared to those with LOD. The role of perinatal transmission in EOD is supported by its association with chorioamnionitis, vaginal delivery, and pneumonia. Dissemination and cardiovascular involvement are common, and affected infants often die. Empiric treatment should be considered for ELBW infants delivered vaginally who have pneumonia and whose mothers have chorioamnionitis or an intrauterine foreign body.

Epidemiology of invasive fungal infections during induction therapy in adults with acute lymphoblastic leukemia: a GRAALL-2005 study.

Little data have been published concerning invasive fungal infections during treatment of acute lymphoblastic leukemia (ALL). Patients included between May 2006 and October 2012 in the multicenter phase III trial for newly diagnosed ALL (GRAALL-2005) were retrospectively reviewed for the occurrence of IFI using the EORTC modified criteria. These patients did not routinely receive antifungal prophylaxis. Among 969 patients included (median age 47 years), 65 (6.7%) developed IFI during induction chemotherapy: 26 (3.3%) invasive aspergillosis (IA), 33 (3.4%) invasive candidiasis (IC) and six other IFI. For IA, the median time between induction therapy and IA diagnosis was 20 days. Diagnosis was probable in 22 cases and proven in four. Aspergillus antigen in serum was tested in all cases and positive in 24. Overall 12-week mortality after diagnosis of IA was 5/26 and attributable mortality related to the infection was 4/26 (15.4%). For IC, the median time between induction therapy and diagnosis was 19 days. Diagnosis was proven in 29 episodes. Candida albicans was the major pathogen in yeast infections (16/27). Overall 12-week mortality after diagnosis of IC was 8/33 (24.2%) and attributable mortality related to the infection was 7/33. The median delay between induction chemotherapy initiation and attributable death related to IC was 15 days. These findings may help to optimize the future management of ALL patients, and as in AML advocate systematic monitoring and the development of prophylactic or preemptive antifungal treatments.

ECIL-6 guidelines for the treatment of invasive candidiasis, aspergillosis and mucormycosis in leukemia and hematopoietic stem cell transplant patients.

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

Predictors of choice of initial antifungal treatment in intraabdominal candidiasis.

Intraabdominal candidiasis (IAC) is the second most frequent form of invasive candidiasis, and is associated with high mortality rates. This study aims to identify current practices in initial antifungal treatment (IAT) in a real-world scenario and to define the predictors of the choice of echinocandins or azoles in IAC episodes. Secondary analysis was performed of a multinational retrospective cohort at 13 teaching hospitals in four countries (Italy, Greece, Spain and Brazil), over a 3-year period (2011-2013). IAC was identified in 481 patients, 323 of whom received antifungal therapy (classified as the treatment group). After excluding 13 patients given amphotericin B, the treatment group was further divided into the echinocandin group (209 patients; 64.7%) and the azole group (101 patients; 32.3%). Median APACHE II scores were significantly higher in the echinocandin group (p 0.013), but IAT did not differ significantly with regard to the Candida species involved. Logistic multivariate stepwise regression analysis, adjusted for centre effect, identified septic shock (adjusted OR (aOR) 1.54), APACHE II >15 (aOR 1.16) and presence in surgical ward at diagnosis (aOR 1.16) as the top three independent variables associated with an empirical echinocandin regimen. No differences in 30-day mortality were observed between groups. Echinocandin regimen was the first choice for IAT in patients with IAC. No statistical differences in mortality were observed between regimens, but echinocandins were administered to patients with more severe disease. Some disagreements were identified between current clinical guidelines and prescription of antifungals for IAC at the bedside, so further educational measures are required to optimize therapies.

[Invasive yeast infections in neutropenic patients]. / Enfermedades invasoras por hongos levaduriformes en pacientes neutropénicos.

Invasive fungal diseases caused by yeasts still play an important role in the morbidity and mortality in neutropenic patients with haematological malignancies. Although the overall incidence of invasive candidiasis has decreased due to widespread use of antifungal prophylaxis, the incidence of non-Candida albicans Candida species is increasing compared with that of C.albicans, and mortality of invasive candidiasis continues to be high. In addition, there has been an increase in invasive infections caused by an array of uncommon yeasts, including species of the genus Malassezia, Rhodotorula, Trichosporon and Saprochaete, characterised by their resistance to echinocandins and poor prognosis.

[Invasive yeast infections in severely burned patients]. / Enfermedades invasivas por hongos levaduriformes en pacientes quemados graves.

Currently, there are few studies on candidaemia in the severely burned patient. These patients share the same risk factors for invasive fungal infections as other critically ill patients, but have certain characteristics that make them particularly susceptible. These include the loss of skin barrier due to extensive burns, fungal colonisation of the latter, and the use of hydrotherapy or other topical therapies (occasionally with antimicrobials). In addition, the increased survival rate achieved in recent decades in critically burned patients due to the advances in treatment has led to the increase of invasive Candida infections. This explains the growing interest in making an earlier and more accurate diagnosis, as well as more effective treatments to reduce morbidity and mortality of candidaemia in severe burned patients. A review is presented on all aspects of the burned patient, including the predisposition and risk factors for invasive candidiasis, pathogenesis of candidaemia, underlying immunodeficiency, local epidemiology and antifungal susceptibility, evolution and prognostic factors, as well as other non-Candida yeast infections. Finally, we include specific data on our local experience in the management of candidaemia in severe burned patients, which may serve to quantify the problem, place it in context, and offer a realistic perspective.

High rate of Candida deep-seated infection in patients under chronic hemodialysis with extended central venous catheter use.

BACKGROUND: Hemodialysis has been described as an important risk factor for the development of candidemia in patients suffering from chronic renal failure. AIMS: The aim of this study was to evaluate the epidemiology of candidemia in outpatients with renal replacement therapy (RRT) by hemodialysis where the fungemia clearly represents a healthcare-associated infection. METHODS: We retrospectively collected clinical and laboratory data from patients undergoing at least 3 months of RRT by hemodialysis who developed candidemia within 48h of hospital admission. RESULTS: We identified 14 patients with candidemia with central venous catheters (CVC) in place for 11-277 days before developing fungemia. Deep-seated infection was documented in 6 out of 14 candidiasis cases (43%), including 5 cases of endocarditis (36%). CONCLUSIONS: CVC in patients under RRT should be promptly replaced by fistulas and grafts to avoid bloodstream infections. Facing a case of candidemia, adequate source control and prompt initiation of antifungal therapy are mandatory to avoid morbidity and mortality.
