Abstract
BACKGROUND Candida bloodstream infections most often affect those already suffering serious, potentially life-threatening conditions and often cause significant morbidity and mortality. Most affected persons have a central venous catheter (CVC) in place. The best CVC management in these cases has been widely debated in recent years, while the incidence of candidaemia has markedly increased. OBJECTIVES The main purpose of this review is to examine the impact of removing versus retaining a CVC on mortality in adults and children with candidaemia who have a CVC in place. SEARCH METHODS We searched the following databases from inception to 3 December 2015: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid SP), EMBASE (Ovid SP), the Commonwealth Agricultural Bureau (CAB), Web of Science and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We searched for missed, unreported and ongoing trials in trial registries and in reference lists of excluded articles. SELECTION CRITERIA We searched for randomized controlled trials (RCTs) and quasi-RCTs involving adults and children with candidaemia and in which participants were randomized for removal of a CVC (the intervention under study), irrespective of publication status, date of publication, blinding status, outcomes published or language.However, two major factors make the conduct of RCTs in this population a difficult task: the large sample size required to document the impact of catheter removal in terms of overall mortality; and lack of economic interest from the industry in conducting such a trial. DATA COLLECTION AND ANALYSIS Our primary outcome measure was mortality. Several secondary outcome measures such as required time for clearance of blood cultures for Candida species, frequency of persistent candidaemia, complications, duration of mechanical ventilation and length of stay in the intensive care unit (ICU) and in the hospital were planned, as were various subgroup and sensitivity analyses, according to our protocol. We assessed papers and abstracts for eligibility and resolved disagreements by discussion. However, we were not able to include any RCTs or quasi-RCTS in this review and, as a result, have carried out no meta-analyses. However, we have chosen to provide a brief overview of excluded observational studies. MAIN RESULTS We found no RCT and thus no available data for evaluation of the primary outcome (mortality) nor secondary outcomes or adverse effects. Therefore, we conducted no statistical analysis.A total of 73 observational studies reported on various clinically relevant outcomes following catheter removal or catheter retention. Most of these excluded, observational studies reported a beneficial effect of catheter removal in patients with candidaemia. None of the observational studies reported results in favour of retaining a catheter. However, the observational studies were very heterogeneous with regards to population, pathogens and interventions. Furthermore, they suffered from confounding by indication and an overall high risk of bias. As a consequence, we are not able to provide recommendations or to draw firm conclusions because of the difficulties involved in interpreting the results of these observational studies (very low quality of evidence, GRADE - Grades of Recommendation, Assessment, Development and Evaluation Working Group). AUTHORS' CONCLUSIONS Despite indications from observational studies in favour of early catheter removal, we found no eligible RCTs or quasi-RCTs to support these practices and therefore could draw no firm conclusions. At this stage, RCTs have provided no evidence to support the benefit of early or late catheter removal for survival or other important outcomes among patients with candidaemia; no evidence with regards to assessment of harm or benefit with prompt central venous catheter removal and subsequent re-insertion of new catheters to continue treatment; and no evidence on optimal timing of insertion of a new central venous catheter.

Pharmacokinetic evaluation of liposomal amphotericin B (L-AMB) in patients with invasive fungal infection: Population approach in Japanese pediatrics. Drug Metab Pharmacokinet 2015; 30:400-9. [PMID: 26645511 DOI: 10.1016/j.dmpk.2015.08.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2015] [Revised: 07/16/2015] [Accepted: 08/13/2015] [Indexed: 11/26/2022]
Abstract
UNLABELLED The pharmacokinetic characteristics of liposomal amphotericin B (L-AMB; AmBisome(®)) in patients with invasive fungal infection were investigated. A population pharmacokinetic (PK) model in Japanese pediatric patients was developed based on 159 serum amphotericin B (AMPH-B) concentrations obtained in a post-marketing clinical study. The subjects were 39 patients with a mean age of 8.4 years (SD 4.5) and mean body weight of 27.1 kg (SD 14.1). A two-compartment PK model with zero-order input and first-order elimination was fitted to serum AMPH-B concentrations for L-AMB doses of 1.0, 2.5, and 5.0 mg/kg/day. Body weight showed significant correlations with PK parameters, such as clearance (CL) and distribution volume of the central compartment (Vc). The predicted Cmax/dose and AUC0-24/dose in Japanese pediatric patients were similar to those in non-Japanese pediatric patients and Japanese adult patients. Extremely large increases in Ctrough compared with predicted values were observed in some Japanese pediatric patients, but no relationships with demographic characteristics, clinical laboratory test values, or representative adverse drug reaction (decreased potassium) were found. The population PK parameters in this study are useful for simulating PK profiles of L-AMB and will be helpful for PK exposure comparisons among different populations and in investigations of pharmacokinetic-pharmacodynamic characteristics in patients. CHEMICAL COMPOUNDS Amphotericin B Deoxycholate (PubChem CID:23668620); amphotericin B (PubChem CID:5280965); 3-nitrophenol (PubChem CID:11137); methanol (PubChem CID:887).

Abstract
Invasive Candida infections are important causes of morbidity and mortality in immunocompromised and hospitalised patients. This article provides the joint recommendations of the German-speaking Mycological Society (Deutschsprachige Mykologische Gesellschaft, DMyKG) and the Paul-Ehrlich-Society for Chemotherapy (PEG) for diagnosis and treatment of invasive and superficial Candida infections. The recommendations are based on published results of clinical trials, case-series and expert opinion using the evidence criteria set forth by the Infectious Diseases Society of America (IDSA). Key recommendations are summarised here: The cornerstone of diagnosis remains the detection of the organism by culture with identification of the isolate at the species level; in vitro susceptibility testing is mandatory for invasive isolates. Options for initial therapy of candidaemia and other invasive Candida infections in non-granulocytopenic patients include fluconazole or one of the three approved echinocandin compounds; liposomal amphotericin B and voriconazole are secondary alternatives because of their less favourable pharmacological properties. In granulocytopenic patients, an echinocandin or liposomal amphotericin B is recommended as initial therapy based on the fungicidal mode of action. Indwelling central venous catheters serve as a main source of infection independent of the pathogenesis of candidaemia in the individual patients and should be removed whenever feasible. Pre-existing immunosuppressive treatment, particularly by glucocorticosteroids, ought to be discontinued, if feasible, or reduced. The duration of treatment for uncomplicated candidaemia is 14 days following the first negative blood culture and resolution of all associated symptoms and findings. Ophthalmoscopy is recommended prior to the discontinuation of antifungal chemotherapy to rule out endophthalmitis or chorioretinitis. Beyond these key recommendations, this article provides detailed recommendations for specific disease entities, for antifungal treatment in paediatric patients as well as a comprehensive discussion of epidemiology, clinical presentation and emerging diagnostic options of invasive and superficial Candida infections.

Abstract
BACKGROUND Persistently febrile neutropenic children at risk for invasive fungal infections receive empiric antifungal therapy as a standard of care. However, little is known about the role of echinocandins and liposomal amphotericin B (L-AmB) for empiric antifungal therapy in pediatric patients. METHODS Patients between the ages of 2 to 17 years with persistent fever and neutropenia were randomly assigned to receive caspofungin (70 mg/m loading dose on day 1, then 50 mg/m daily [maximum 70 mg/d]) or L-AmB (3 mg/kg daily) in a 2:1 ratio. Evaluation of safety was the primary objective of the study. Efficacy was also evaluated, with a successful outcome defined as fulfilling all components of a prespecified 5-part composite endpoint. Suspected invasive fungal infections were evaluated by an independent, treatment-blinded adjudication committee. RESULTS Eighty-two patients received study therapy (caspofungin 56, L-AmB 26), and 81 were evaluated for efficacy (caspofungin 56; L-AmB 25). Outcomes for safety and efficacy endpoints were similar for both study arms. Adverse drug-related event rates [95% confidence interval] were similar between the caspofungin and L-AmB groups (clinical 48.2% [34.7-62.0] versus 46.2% [26.6-66.6]; laboratory 10.7% [4.0-21.9] versus 19.2% [6.6-39.4]). Serious drug-related adverse events occurred in 1 (1.8%) of caspofungin-treated patients and 3 (11.5%) of L-AmB-treated patients. Overall success rates [95% CI] were 46.4% [33.4-59.5] for caspofungin and 32.0% [13.7-50.3] for L-AmB. CONCLUSIONS Caspofungin and L-AmB were comparable in tolerability, safety, and efficacy as empiric antifungal therapy for persistently febrile neutropenic pediatric patients.

Abstract
BACKGROUND The incidence of candidemia in pediatric patients follows the same pattern of increase as in adults, but the rate of increase is greater. Pediatric patients in critical condition, particularly young infants, are especially vulnerable to invasive Candida infections (ICI), partly because of their age and severe underlying disease and partly because of the invasive procedures used. DISCUSSION Central venous catheters and arterial lines, parenteral nutrition, mechanical ventilation and extended use of antimicrobials enhance the risk of ICI. C. albicans continues to be the most prevalent isolate. However, an increasing role of non-C. albicans (NAC) spp., some of which are intrinsically or potentially resistant to antifungal agents, has been observed. NAC spp., particularly C. parapsilosis and C. tropicalis, account for almost half of ICI. The increased use of antifungals in immunocompromised patients, mainly prophylactically, is considered the strongest contributory factor to the changes in species distribution, which have subsequently affected the mortality and choice of empirical treatment. CONCLUSIONS Prompt removal of lines and initiation of antifungal treatment are the milestones of management. Conventional amphotericin B remains a commonly used antifungal agent, but its lipid formulations and fluconazole are also used frequently. Novel antifungal agents such as second-generation triazoles and echinocandins exhibit potential as alternative agents in critically ill children with ICI. Although response rates are still far from satisfactory, improved understanding of risk factors, preventive strategies and new treatment options promise a better future outcome.

Abstract
Candidiasis is common in children with cancer, particularly during periods of severe immunosuppression and neutropenia. Our aim was to study the microbiological changes in the oral cavity of children with newly diagnosed cancer. The study group consisted of 30 consecutive children and adolescents, 16 with acute lymphoblastic leukemia and 14 with solid tumors. Oral cultures to detect fungi and bacteria were conducted for all patients before treatment, during and after neutropenic episodes. In 23 patients developing fever simultaneous throat, urine and blood sampling was carried out. No pathogens were found in the cultures taken before the outset (30 cultures) or after recovery from (30 cultures) the neutropenic episodes. In the 45 oral cultures taken during the neutropenic episodes 38 (84.4%) proved positive. Fungi were the most frequently isolated oral pathogens: 33/38 yeast and 6/38 bacterial infections were identified. There was no association between the underlying malignancy and the occurrence of the positive cultures. Of the 30 patients, all 23 (76.7%) who have developed moderate-to-severe neutropenia, developed oral fungal colonization or clinically obvious fungal infection at least on one occasion during the study. In addition to oral samples, fungi were identified in 9/23 pharyngeal swabs, 6/23 urine and 1/23 blood cultures. The initial fungal pathogen was exclusively (33/33) Candida albicans. In extended severe neutropenic states, C. albicans was replaced by non-albicans species (C. kefyr, C. lusitaniae, C. sake, C. tropicalis) in 5 patients between 4 to 6 days of the neutropenic episodes. Four of the nonalbicans Candida strains were resistant to azole-type antifungal agents. Neutropenic episodes of children with cancer are associated with an increased risk of developing oral and even systemic infections with C. albicans that can be replaced by azole-resistant nonalbicans strains in prolonged neutropenia contributing to morbidity of these patients.

Abstract
BACKGROUND Data on epidemiology and survival after fungal infections in patients with cancer are primarily based on studies in adults, whereas few data are available on children. METHODS A prospective, multicenter, 2-year surveillance of fungal infections in children receiving antineoplastic treatment was performed in 15 Italian centers. For each case, defined by means of EORTC-IFIG/NIAID-MSG, information was collected on age, phase of treatment, presence of neutropenia or lymphocytopenia, administration of antifungal drugs and survival. RESULTS Ninety-six episodes (42 proven [19 fungemias, 23 deep tissue infections], 17 probable and 37 possible invasive mycoses) were reported. Most of them (73%) followed aggressive chemotherapy, 21% allogeneic hematopoietic stem cell transplantation and only 6% moderately aggressive treatment. Neutropenia was present in 77% of the episodes, and it had a longer duration before deep tissue mycosis as compared with fungemia (P = 0.020). Lymphocytopenia was present in 75% of the episodes observed in nonneutropenic patients. As compared with children with fungemia, patients with probable invasive mycoses had a 25.7-fold increased risk of death, whereas it was 7.7-fold greater in children with possible invasive mycoses and 5-fold higher in those with proven deep tissue infection (P = 0.004). The risk of death was also 3.8-fold higher in patients already receiving antifungals at the time of diagnosis of infection as compared with those not receiving antimycotic drugs. CONCLUSIONS In children with cancer, aggressive antineoplastic treatment, severe and longlasting neutropenia and lymphocytopenia are associated with fungal infections. These features as the clinical pictures are similar to those reported in adults, but in children, the overall and the infection-specific (fungemia or mycosis with deep tissue infection) mortalities are lower.
