Plasma and Cerebrospinal Fluid Concentrations of Micafungin Administered at High Doses in Critically Ill Infants with Systemic Candidiasis: A Pooled Analysis of Two Studies. Pharmaceuticals (Basel) 2023; 16:ph16030472. [PMID: 36986569 PMCID: PMC10051811 DOI: 10.3390/ph16030472] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 03/09/2023] [Accepted: 03/13/2023] [Indexed: 03/30/2023] Open
Abstract
Background: Neonates may require higher doses of micafungin than adults to reach the therapeutic effect for increased plasma clearance. Only poor and inconclusive data are available still now to support this hypothesis, especially with regard to central nervous system micafungin concentrations. To assess the pharmacokinetics of increased doses (8 to 15 mg/kg/day) of micafungin in preterm and term neonates with invasive candidiasis and to complete previously presented results, we analyzed the pharmacokinetic data on a total of 53 newborns treated with micafungin, whereby 3 of them had Candida meningitis and hydrocephalus. Methods: Fifty-three neonates with systemic candidiasis, three of them with meningitis, were treated for at least 14 days with intravenous micafungin (Mycamine®) at a dosage ranging from 8 to 15 mg/kg/day. Plasma and cerebrospinal fluid (CSF) concentrations of micafungin were measured before the drug administration and at 1, 2, and 8 h after the end of the infusion using high-performance liquid chromatography (HPLC). Systemic exposure was assessed according to AUC0-24, plasma clearance (CL), and half-life measured in 52/53 patients, divided by chronological age. Results and conclusions: The mean micafungin clearance is higher in neonates than in older infants (0.036 L/h/kg before 28 days of life versus 0.028 L/h/kg after 120 days). The drug half-life is shorter in neonates than in older patients (13.5 h before 28 days of life versus 14.4 h after 120 days). With doses ranging between 8 and 15 mg/kg/day, micafungin crosses the blood-brain barrier reaching therapeutic levels in CSF.

Abstract
Most invasive fungal infections are opportunistic in nature but the epidemiology is constantly changing, with new risk groups being identified. Neutropenia is a classical risk factor for fungal infections, while critically ill patients in the ICU are now increasingly at risk of yeast and mould infections. Factors to be considered when choosing antifungal treatment include the emergence of rarer fungal pathogens, the risk of resistance to azoles and echinocandins and the possibility of drug-drug interactions. Liposomal amphotericin B has retained its place in the therapeutic armamentarium based on its clinical profile: a broad spectrum of antifungal activity with a low risk of resistance, predictable pharmacokinetics with a rapid accumulation at the infection site (including biofilms), a low potential for drug-drug interactions and a low risk of acute and chronic treatment-limiting toxicities versus other formulations of amphotericin B. It is a suitable choice for the first-line empirical or pre-emptive treatment of suspected fungal infections in neutropenic haematology patients and is an excellent alternative for patients with documented fungal disease who can no longer tolerate or continue their first-line azole or echinocandin therapy, both in the haematology setting and in the ICU. Moreover, it is the first-line drug of choice for the treatment of invasive mucormycosis. Finally, liposomal amphotericin B is one of the few antifungal agents approved for use in children of all ages over 1 month and is included in paediatric-specific guidelines for the management of fungal disease.

Abstract
Invasive fungal diseases (IFDs) are a relevant cause of morbidity and mortality in children with cancer. Their correct prevention and management impact patients’ outcomes. The aim of this review is to highlight the rationale and novel insights into antifungal prophylaxis and treatment in pediatric patients with oncological and hematological diseases. The literature analysis showed that IFDs represent a minority of cases in comparison to bacterial and viral infections, but their impact might be far more serious, especially when prolonged antifungal therapy or invasive surgical treatments are required to eradicate colonization. A personalized approach is recommended since pediatric patients with cancer often present with different complications and require tailored therapy. Moreover, while the Aspergillus infection rate does not seem to increase, in the near future, new therapeutic recommendations should be required in light of new epidemiological data on Candidemia due to resistant species. Finally, further studies on CAR-T treatment and other immunotherapies are needed in patients with unique needs and the risk of complications. Definitive guidelines on IFD treatment considering the evolving epidemiology of antifungal resistance, new therapeutic approaches in pediatric cancer, novel antifungal drugs and the importance of an appropriate antifungal stewardship are urgently needed.

Abstract
Purpose of review The goal of this review was to provide an update on the prevention and treatment options for invasive candidiasis (IC) in the neonatal intensive care unit (NICU) and pediatric intensive care unit (PICU). Recent findings Studies have further validated the use of fluconazole for IC prophylaxis among high-risk patients in the NICU. It remains unclear if prophylaxis leads to resistance development and the ideal dosage regimen is still not clear. Recent studies have been published comparing caspofungin and micafungin to amphotericin B and illustrated similar efficacy outcomes in the NICU. Micafungin now has approval from the United States Food and Drug Administration (FDA) for use in infants < 4 months of age. Prophylactic strategies in the PICU could include zinc and vitamin D. Anidulafungin has recent non-comparative data supporting use in pediatric patients older than 1 month of age and also has a recent FDA approval for use in children 1 month of age and older. Summary Fluconazole prophylaxis remains a reasonable strategy in select NICU patients, although further analyses of resistance and the optimal dosage regimen are needed. Echinocandins are potential therapeutic options for non-meningitis or urinary tract infections in both the neonatal and pediatric population.

Abstract
Candida albicans causes life-threatening disseminated candidiasis. Individuals at greatest risk have weakened immune systems. An outer cell wall, exopolysaccharide matrix, and biofilm rich in oligoglucans and oligomannans help Candida spp. evade host defenses. Even after antifungal treatment, the 1-year mortality rate exceeds 25%. Undoubtedly, there is room to improve drug performance. The mammalian C-type lectin pathogen receptors Dectin-1 and Dectin-2 bind to fungal oligoglucans and oligomannans, respectively. We previously coated amphotericin B-loaded liposomes, AmB-LLs, pegylated analogs of AmBisome, with the ligand binding domains of these two Dectins. DectiSomes, DEC1-AmB-LLs and DEC2-AmB-LLs, showed two distinct patterns of binding to the exopolysaccharide matrix surrounding C. albicans hyphae grown in vitro. Here we showed that DectiSomes were preferentially associated with fungal colonies in the kidneys. In a neutropenic mouse model of candidiasis, DEC1-AmB-LLs and DEC2-AmB-LLs delivering only one dose of 0.2 mg/kg AmB reduced the kidney fungal burden several fold relative to AmB-LLs. DEC1-AmB-LLs and DEC2-AmB-LLs increased the percent of surviving mice 2.5-fold and 8.3-fold, respectively, relative to AmB-LLs. Dectin-2 targeting of anidulafungin loaded liposomes, DEC2-AFG-LLs, and of commercial AmBisome, DEC2-AmBisome, reduced fungal burden in the kidneys several fold over their untargeted counterparts. The data herein suggest that targeting of a variety of antifungal drugs to fungal glycans may achieve lower safer effective doses and improve drug efficacy against a variety of invasive fungal infections.

Abstract
INTRODUCTION Neonates and young infants with invasive candidiasis are particularly at increased risk of dissemination including hematogenous Candida meningoencephalitis. The echinocandins including micafungin have emerged as a preferred agent in most cases of candidemia and invasive candidiasis but data in pediatric patients under 4 months of age are limited. AREAS COVERED In this report, we review the micafungin use in infants younger than 4 months of age. Animal studies as well as clinical data that support its use in neonatal candidiasis are reviewed. In addition, the status of FDA approval and the rationale of micafungin dosing recommendations in infants <4 months are discussed. EXPERT OPINION A dose of 4 mg/kg was approved for treatment of candidemia, Candida peritonitis and abscesses excluding meningoencephalitis or ocular involvement in patients younger than 4 months of age. However, because of the risk of central nervous system dissemination as well as the difficulty in establishing this diagnosis, this dose is inadequate to treat ill infants with candidemia. More studies are needed to establish the safety and efficacy of micafungin daily dose of at least 10 mg/kg in infants younger than 4 months of age when hematogenous Candida meningoencephalitis or ocular involvement cannot be excluded.

Abstract
BACKGROUND Detailed reporting is essential in non-inferiority randomized controlled trials (NI-RCTs) to assess evidence quality, as these trials inform standards of care. OBJECTIVES The primary objective was to evaluate the methodological and reporting quality of antifungal NI-RCTs. DATA SOURCES Medline, EMBASE, the Cochrane CENTRAL and the United States Federal Drug Administration (FDA) drugs database were searched to 9 September 2020. STUDY ELIGIBILITY CRITERIA NI-RCTs differing by antifungal formulation, type, dose, administration and/or duration were included. Articles were independently assessed in duplicate using quality indicators developed by the Consolidated Standards of Reporting Trials (CONSORT) group. PARTICIPANTS Patients enrolled in antifungal trials for prophylactic and therapeutic use. METHODS The Cochrane RoB 2.0 tool was used to assess risk of bias. Descriptive statistics were used; all statistical tests were two sided. RESULTS Of 32 included studies, 22 (68.7%) did not justify the NIM. Handling of missing data was not described in 20 (62.5%). Intention-to-treat (ITT) and per-protocol (PP) analyses were both reported in 12/32 (37.5%) studies. Eleven of 32 studies (34.3%) reported potentially misleading conclusions. Industry-financed studies were more likely to report only the ITT analysis (n = 14/27, 51.9%). Methodological and reporting quality was unaffected by publication year; risk of bias from missing data changed over time. Overall risk of bias across included studies was moderate to high, with high risk in randomization process (n = 8/32, 25%), missing outcome data (n = 5/32, 15.6%), and selection of reported result (n = 9/32, 28.1%). CONCLUSIONS Justification of the non-inferiority margin, reporting of ITT and PP analyses, missing data handling description, and ensuring conclusions are consistent with reported data is necessary to improve CONSORT adherence. Small sample size and overall risk of bias are study limitations. (Systematic Review Registration Number PROSPERO CRD42020219497).

Abstract
Non-inferiority randomized controlled trial (RCT) effectiveness may erode when results favour the active control over time, and when a decreasingly effective control arm is used in serial trials. We analyzed 32 antifungal noninferiority RCTs (NI-RCTs) for these scenarios in this secondary analysis of a systematic review. Our exploratory analysis suggests that the erosion risk in the effectiveness of antifungal non-inferiority trials is uncommon. Findings are limited by small sample size, and overall risk of bias.

Abstract
BACKGROUND Invasive candidiasis is the most common invasive fungal disease in children and adolescents, but there are limited pediatric-specific antifungal effectiveness data. We compared the effectiveness of echinocandins to triazoles or amphotericin B formulations (triazole/amphotericin B) as initial directed therapy for invasive candidiasis. METHODS This multinational observational cohort study enrolled patients aged >120 days and <18 years with proven invasive candidiasis from January 1, 2014, to November 28, 2017, at 43 International Pediatric Fungal Network sites. Primary exposure was initial directed therapy administered at the time qualifying culture became positive for yeast. Exposure groups were categorized by receipt of an echinocandin vs receipt of triazole/amphotericin B. Primary outcome was global response at 14 days following invasive candidiasis onset, adjudicated by a centralized data review committee. Stratified Mantel-Haenszel analyses estimated risk difference between exposure groups. RESULTS Seven-hundred and fifty invasive candidiasis episodes were identified. After exclusions, 541 participants (235 in the echinocandin group and 306 in the triazole/amphotericin B group) remained. Crude failure rates at 14 days for echinocandin and triazole/amphotericin B groups were 9.8% (95% confidence intervals [CI]: 6.0% to 13.6%) and 13.1% (95% CI: 9.3% to 16.8%), respectively. The adjusted 14-day risk difference between echinocandin and triazole/amphotericin B groups was -7.1% points (95% CI: -13.1% to -2.4%), favoring echinocandins. The risk difference was -0.4% (95% CI: -7.5% to 6.7%) at 30 days. CONCLUSIONS In children with invasive candidiasis, initial directed therapy with an echinocandin was associated with reduced failure rate at 14 days but not 30 days. These results may support echinocandins as initial directed therapy for invasive candidiasis in children and adolescents. CLINICAL TRIALS REGISTRATION NCT01869829.

Abstract
INTRODUCTION Invasive fungal infections are an important cause of morbidity and mortality in infants, particularly in extreme prematurity. Successful systemic treatment requires consideration of antifungal efficacy, safety, and pharmacokinetics, including optimization of dosing in this population. AREAS COVERED This review summarizes published pharmacokinetic data on four classes of antifungal agents used in the neonatal population. Alterations in absorption, distribution, drug metabolism and clearance in infants compared to adult populations are highlighted. Additionally, pharmacodynamics, safety, and therapeutic drug monitoring are discussed. Recent advancements in neonatal antifungal pharmacotherapies are examined, with emphasis on clinical application. EXPERT OPINION Over the last two decades, published studies have provided increased knowledge on pharmacokinetic considerations in the neonatal population. Future research should focus on filling in the knowledge gaps that remain regarding the benefits and risks of combination antifungal therapy, the rising use of micafungin for invasive candidiasis given its fungicidal activity against polyene and azole-resistant Candida species and its minimal adverse effect profile, and the need for pharmacokinetic and safety data of broad spectrum triazoles, like voriconazole and posaconazole, in infants. Furthermore, efforts should focus on well-designed trials, including population pharmacokinetic studies, to develop dosing recommendations with subsequent implementation into clinical practice.

Abstract
BACKGROUND Invasive fungal diseases remain a major cause of morbidity and mortality in cancer patients undergoing intensive cytotoxic therapy. The choice of the most appropriate antifungal treatment (AFT) depends on the fungal species suspected or identified, the patient's risk factors (eg length and depth of granulocytopenia) and the expected side effects. OBJECTIVES Since the last edition of recommendations for 'Treatment of invasive fungal infections in cancer patients' of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO) in 2013, treatment strategies were gradually moving away from solely empirical therapy of presumed or possible invasive fungal diseases (IFDs) towards pre-emptive therapy of probable IFD. METHODS The guideline was prepared by German clinical experts for infections in cancer patients in a stepwise consensus process. MEDLINE was systematically searched for English-language publications from January 1975 up to September 2019 using the key terms such as 'invasive fungal infection' and/or 'invasive fungal disease' and at least one of the following: antifungal agents, cancer, haematological malignancy, antifungal therapy, neutropenia, granulocytopenia, mycoses, aspergillosis, candidosis and mucormycosis. RESULTS AFT of IFDs in cancer patients may include not only antifungal agents but also non-pharmacologic treatment. In addition, the armamentarium of antifungals for treatment of IFDs has been broadened (eg licensing of isavuconazole). Additional antifungals are currently under investigation or in clinical trials. CONCLUSIONS Here, updated recommendations for the treatment of proven or probable IFDs are given. All recommendations including the levels of evidence are summarised in tables to give the reader rapid access to key information.

Abstract
Echinocandins are used for treatment of invasive candidiasis, but data on their use in children are limited. We sought to describe the epidemiology of echinocandin use in hospitalized children in the United States. We performed a retrospective cohort study of children <18 years of age hospitalized between January 2005 and December 2015 and exposed to ≥1 day of a systemic antifungal agent using the Pediatric Health Information System (PHIS) database. Univariate analyses compared recipients of two echinocandin agents, caspofungin and micafungin. Crude prescribing rates of each antifungal group were calculated across hospitals and per year. The rate of antifungal agent prescribing over time was assessed using two-level mixed-effects negative binomial regression, accounting for variability in prescribing by hospital over time. From 2005 to 2015, fluconazole was prescribed most often (n = 148,859, 74.3%), followed by mould-active triazoles (n = 36,131, 18.0%), amphotericin products (n = 29,008, 14.5%), and echinocandins (n = 28,371, 14.2%). The crude rate of systemic antifungal prescribing decreased across all PHIS hospitals from 36.3 to 33.8 per 1000 admissions during the study period, but echinocandin prescribing increased from 2.2 to 7.2 per 1000 admissions. A mixed effects regression model revealed that echinocandin prescribing increased by 15.1% per year (95% CI 11.2-19.2). Echinocandin administration increased from 6.1% to 21.0% of admissions during which a systemic antifungal agent was given. In conclusion, echinocandin use has increased significantly over time, accounting for an increasing proportion of systemic antifungal prescribing in children.

Abstract
OBJECTIVE The aim of this meta-analysis was to assess the efficacy and safety of treatment with echinocandins compared with amphotericin B in paediatric patients with invasive candidiasis. METHODS PubMed, Embase and Cochrane databases were searched up to August 2018. Only randomized controlled trials (RCTs) evaluating echinocandins and amphotericin B in the treatment of paediatric patients with invasive candidiasis were included. The outcomes were clinical responses and adverse effects. RESULTS Five RCTs of 354 patients (191 patients in the echinocandins group and 163 patients in the amphotericin B group) were included in this study. Overall, no significant differences in clinical response were found between echinocandins and amphotericin B (odds ratio [OR], 1.38; 95% confidence interval [CI], 0.68-2.80; I2 = 39%). Similar results were also observed in the high-risk group (OR, 3.10; 95% CI, 0.10-97.23; I2 = 76%), the low-risk group (OR, 1.29; 95% CI, 0.36-4.62; I2 = 21%) and the neutropenia group (OR, 1.56; 95% CI, 0.75-3.26; I2 = 0%). The risk of discontinuing treatment because of adverse effects was significantly lower in the echinocandins group than in the amphotericin B group (OR, 0.30, 95% CI, 0.12-0.76; I2 = 0%). CONCLUSIONS There were no differences in efficacy between the echinocandins group and the amphotericin B group in the treatment of invasive candidiasis in paediatric patients. However, the echinocandins group had a significantly lower risk of discontinuing treatment than the amphotericin B group.

Abstract
BACKGROUND Treatment with an echinocandin is recommended as first-line therapy for patients with invasive candidiasis (ICC) including candidemia. Little is known about the efficacy and safety of anidulafungin in children with ICC. METHODS Eligible patients with ICC 2 to <18 years old were enrolled into this prospective, open-label, noncomparative, international study (NCT00761267) and received anidulafungin for 10-35 days (3 mg/kg on day 1, 1.5 mg/kg daily thereafter). Safety was assessed through week 6 follow-up. Efficacy, measured by global response (based on clinical and microbiologic responses), was assessed at end of intravenous treatment (EOIVT), end of treatment, weeks 2 and 6 follow-up. RESULTS Forty-nine patients (n = 19, 2 to <5 years; n = 30, 5 to <18 years) received ≥1 dose of anidulafungin (median 11 days; range 1-35 days) and were assessed for safety. Among 48 patients with a Candida species isolated, C. albicans (37.5%), C. parapsilosis (25.0%), C. tropicalis (14.6%) and C. lusitaniae (10.4%) were the most frequent Candida spp. All patients reported ≥1 treatment-emergent adverse event, with diarrhea (22.4%), vomiting (24.5%) and pyrexia (18.4%) being most frequent. Five patients discontinued treatment because of adverse events, of which 4 discontinuations were considered related to anidulafungin. All-cause mortality was 8.2% (4/49) by EOIVT and 14.3% (7/49) by week 6 follow-up. None of 7 deaths during the study period were considered treatment related. Global response success rate was 70.8% at EOIVT. CONCLUSIONS These data support the use of anidulafungin as a treatment option for ICC in children 2 to <18 years old at the studied dose.

Abstract
INTRODUCTION Invasive candidiasis (IC) can be a life-threatening infection in immunocompromised patients, particularly those with cancer, hematologic diseases and/or hematopoietic stem cell transplantation (HSCT) recipients. The objective of this study was to evaluate the effectiveness of micafungin in patients with hematologic malignancies or HSCT recipients, relevant to clinical presentation of IC, in real-life practice in Greece. METHODS ASPIRE was a phase IV, multicenter, non-interventional, prospective cohort study, conducted at ten tertiary hospitals in Greece, in adults with hematologic disease. Micafungin treatment for IC or prophylaxis for Candida infection was administered per standard clinical practice until a clinical outcome (success or failure) was reached. Treatment success was defined by the EORTC/MSG criteria for invasive fungal infections (IFI) and was assessed by the investigator. Treatment discontinuation and safety were also evaluated. RESULTS One hundred forty-three patients were enrolled. Median age was 62; 85 (59.4%) patients were male, and 133 (93.0%) had Greek ethnicity. One hundred twenty-six (88.1%) patients had hematologic malignancies, and 21 (14.7%) had received HSCT. Prophylaxis was administered to 74 (51.7%) patients [median (range) dose: 50 (50-150) mg/day] with no signs of IFI. Overall, 52 (36.4%) patients with possible IFI at baseline received micafungin treatment [100 (50-125) mg/day] versus 12 (17.2%) with probable [100 (75-150) mg/day] and 5 (3.5%) with confirmed [125 (100-150) mg/day] IFI. Treatment success was 91.6% (95% CI 85.80-95.59; n = 131) overall and 90.5% (n = 67) in patients receiving prophylaxis. Median time on treatment was 13 days. Treatment discontinuation (n = 26; 18.2%) was not related to adverse events. No treatment-related serious adverse events were reported. CONCLUSION Micafungin treatment for IC or prophylaxis for Candida infection was effective and well tolerated in patients with hematologic disorders in clinical practice in Greece. These results demonstrate that micafungin could be used more widely for prophylaxis. Further work is required to determine the efficacy and safety of micafungin for the management of IFIs in hematologic settings. FUNDING Astellas Pharma Inc.

Abstract
This paper reviews recent advances in three selected areas of pediatric invasive candidiasis: epidemiology, diagnosis, and treatment. Although the epidemiological trends of pediatric invasive candidiasis illustrate a declining incidence, this infection still carries a heavy burden of mortality and morbidity that warrants a high index of clinical suspicion, the need for rapid diagnostic systems, and the early initiation of antifungal therapy. The development of non-culture-based technologies, such as the T2Candida system and (1→3)-β-d-glucan detection assay, offers the potential for early laboratory detection of candidemia and CNS candidiasis, respectively. Among the complications of disseminated candidiasis in infants and children, hematogenous disseminated Candida meningoencephalitis (HCME) is an important cause of neurological morbidity. Detection of (1→3)-β-d-glucan in cerebrospinal fluid serves as an early diagnostic indicator and an important biomarker of therapeutic response. The recently reported pharmacokinetic data of liposomal amphotericin B in children demonstrate dose–exposure relationships similar to those in adults. The recently completed randomized clinical trial of micafungin versus deoxycholate amphotericin B in the treatment of neonatal candidemia provides further safety data for an echinocandin in this clinical setting.

Abstract
BACKGROUND Echinocandins are recommended for the treatment of suspected or confirmed invasive candidiasis (IC) in adults. Less is known about the use of echinocandins for the management of IC in children. The aim of this study was to investigate the overall efficacy and safety of echinocandin class in neonatal and pediatric patients with IC. METHODS PubMed, Cochrane Central, Scopus and Clinical trial registries were searched up to July 27, 2017. Eligible studies were randomized controlled trials that evaluated the efficacy and safety of any echinocandin versus agents of other antifungal classes for the treatment of IC in pediatric patients. The primary outcome was treatment success with resolution of symptoms and signs, and absence of IC. In the meta-analysis a random effects model was used, and the odds ratio (OR) and 95% confidence intervals (CIs) were calculated. RESULTS Four randomized clinical trials (324 patients), 2 confirmed IC (micafungin vs. liposomal amphotericin B (L-AmB) and caspofungin vs. L-AmB) and 2 empirical therapy trials (caspofungin vs. deoxycholate amphotericin B and caspofungin vs. L-AmB) were included. There was no significant difference between echinocandins and comparator in terms of treatment success (OR = 1.61, 95% CI: 0.74-3.50) and incidence of treatment-related adverse events (OR = 0.70, 95% CI: 0.39-1.26). However, fewer children treated with echinocandins discontinued treatment because of adverse events than amphotericin B formulations (OR = 0.26, 95% CI: 0.08-0.82, P = 0.02). CONCLUSIONS In the treatment of IC in children, echinocandins show non-inferior efficacy compared with amphotericin B formulations with fewer discontinuations than in comparator arm.

Abstract
The main indications for antifungal drug administration in pediatrics are reviewed as well as an update of the data of antifungal agents and antifungal policies performed. Specifically, antifungal therapy in three main areas is updated as follows: a) Prophylaxis of premature neonates against invasive candidiasis; b) management of candidemia and meningoencephalitis in neonates; and c) prophylaxis, empiric therapy, and targeted antifungal therapy in children with primary or secondary immunodeficiencies. Fluconazole remains the most frequent antifungal prophylactic agent given to high-risk neonates and children. However, the emergence of fluconazole resistance, particularly in non-albicans Candida species, should be considered during preventive or empiric therapy. In very-low birth-weight neonates, although fluconazole is used as antifungal prophylaxis in neonatal intensive care units (NICU's) with relatively high incidence of invasive candidiasis (IC), its role is under continuous debate. Amphotericin B, primarily in its liposomal formulation, remains the mainstay of therapy for treating neonatal and pediatric yeast and mold infections. Voriconazole is indicated for mold infections except for mucormycosis in children >2 years. Newer triazoles-such as posaconazole and isavuconazole-as well as echinocandins, are either licensed or under study for first-line or salvage therapy, whereas combination therapy is kept for refractory cases.

Abstract
BACKGROUND Amphotericin B deoxycholate (AmB-D) is standard of care treatment for neonatal invasive candidiasis (IC). Micafungin (MCA) has broad-spectrum fungicidal activity against Candida spp. We compared the efficacy and safety of intravenous MCA with intravenous AmB-D and assessed the pharmacokinetics of MCA in infants >2-120 days of age with proven IC in a phase 3, randomized, double-blind, multicenter, parallel-group, noninferiority study (NCT00815516). METHODS Infants were randomized 2:1 to MCA (10 mg/kg/d) or AmB-D (1 mg/kg/d) for ≥21 days. Primary efficacy endpoint was fungal-free survival (FFS) 1 week after last study drug dose. MCA population pharmacokinetics included simulated area under the curve (AUC) at steady state and maximum plasma concentration after 2-hour infusion. AUC pharmacodynamic target exposure was 170 µg·h/mL. RESULTS Thirty infants received MCA (n = 20) or AmB-D (n = 10). The trial was terminated early because of slow recruitment. FFS was observed in 12 of 20 [60%; 95% confidence interval (CI): 36%-81%] MCA-group infants and in 7 of 10 (70%; 95% CI: 35%-93%) AmB-D-group infants. The most common treatment-emergent adverse events were anemia [MCA: n = 9 (45%); AmB-D: n = 3 (30%)] and thrombocytopenia [n = 2 (10%) and n = 3 (30%), respectively]. Model-derived mean AUC at steady state for MCA was 399.3 ± 163.9 µg·h/mL (95% prediction interval: 190.3-742.3 µg/mL); steady state and maximum plasma concentration after 2-hour infusion was 31.1 ± 10.5 µg/mL (95% prediction interval: 17.0-49.7 µg/mL). MCA exposures were above the AUC pharmacodynamic target exposure. CONCLUSIONS Within the study limitations, infants with IC treated with MCA achieved similar FFS compared with AmB-D. Both agents were safe and well tolerated.

Abstract
BACKGROUND Neonatal candidiasis causes significant morbidity and mortality in high risk infants. The micafungin dosage regimen of 10 mg/kg established for the treatment of neonatal candidiasis is based on a laboratory animal model of neonatal hematogenous Candida meningoencephalitis and pharmacokinetic (PK)-pharmacodynamic (PD) bridging studies. However, little is known about the how these PK-PD data translate clinically. METHODS Micafungin plasma concentrations from infants were used to construct a population PK model using Pmetrics software. Bayesian posterior estimates for infants with invasive candidiasis were used to evaluate the relationship between drug exposure and mycologic response using logistic regression. RESULTS Sixty-four infants 3-119 days of age were included, of which 29 (45%) infants had invasive candidiasis. A 2-compartment PK model fits the data well. Allometric scaling was applied to clearance and volume normalized to the mean population weight (kg). The mean (standard deviation) estimates for clearance and volume in the central compartment were 0.07 (0.05) L/h/1.8 kg and 0.61 (0.53) L/1.8 kg, respectively. No relationship between average daily area under concentration-time curve or average daily area under concentration-time curve:minimum inhibitory concentration ratio and mycologic response was demonstrated (P > 0.05). Although not statistically significant, mycologic response was numerically higher when area under concentration-time curves were at or above the PD target. CONCLUSIONS While a significant exposure-response relationship was not found, PK-PD experiments support higher exposures of micafungin in infants with invasive candidiasis. More patients would clarify this relationship; however, low incidence deters the feasibility of these studies.

Abstract
Neutropenia is linked to the development of invasive candidiasis/candidaemia, for which micafungin has demonstrated efficacy, but evidence in patients with neutropenia is limited. The aim of this study was to evaluate the efficacy of micafungin for the treatment of invasive candidiasis/candidaemia in patients with neutropenia (<500 neutrophils/μL) and without neutropenia. This pooled, post hoc analysis of 2 Phase 3 trials compared micafungin 100 mg/d (adults) and 2 mg/kg/d (paediatrics) with L-AmB 3 mg/kg/d (NCT00106288) and micafungin 100 mg/d and 150 mg/d with caspofungin 70 mg/d followed by 50 mg/d (adults) (NCT00105144); treatment duration 2-4 weeks (≤8 weeks for chronic disseminated candidiasis). Effects of neutropenia duration and Candida spp. on efficacy outcomes (treatment success, clinical and mycological response) were examined. Of 685 patients, 77 had neutropenia. The most common infection in patients with/without neutropenia was due to C. tropicalis (31/77) and C. albicans (295/608) respectively. Overall success was numerically lower in patients with vs without neutropenia (63.6% vs 72.9%). Clinical and mycological response was similar between groups. Neutropenia duration or Candida spp. did not impact micafungin's overall success rate. This analysis supports evidence that micafungin is effective against invasive candidiasis/candidaemia in patients with neutropenia, irrespective of neutropenia duration or Candida spp., although overall success may be lower than in patients without neutropenia.

Abstract
BACKGROUND Previous evidence-based guidelines on the management of intra-abdominal infection (IAI) were published by the Surgical Infection Society (SIS) in 1992, 2002, and 2010. At the time the most recent guideline was released, the plan was to update the guideline every five years to ensure the timeliness and appropriateness of the recommendations. METHODS Based on the previous guidelines, the task force outlined a number of topics related to the treatment of patients with IAI and then developed key questions on these various topics. All questions were approached using general and specific literature searches, focusing on articles and other information published since 2008. These publications and additional materials published before 2008 were reviewed by the task force as a whole or by individual subgroups as to relevance to individual questions. Recommendations were developed by a process of iterative consensus, with all task force members voting to accept or reject each recommendation. Grading was based on the GRADE (Grades of Recommendation Assessment, Development, and Evaluation) system; the quality of the evidence was graded as high, moderate, or weak, and the strength of the recommendation was graded as strong or weak. Review of the document was performed by members of the SIS who were not on the task force. After responses were made to all critiques, the document was approved as an official guideline of the SIS by the Executive Council. RESULTS This guideline summarizes the current recommendations developed by the task force on the treatment of patients who have IAI. Evidence-based recommendations have been made regarding risk assessment in individual patients; source control; the timing, selection, and duration of antimicrobial therapy; and suggested approaches to patients who fail initial therapy. Additional recommendations related to the treatment of pediatric patients with IAI have been included. SUMMARY The current recommendations of the SIS regarding the treatment of patients with IAI are provided in this guideline.

Abstract
Intravenous micafungin (Mycamine®; Funguard®), an echinocandin, is approved in the EU for the treatment of invasive candidiasis in children (including neonates) and adolescents (<16 years of age) and as prophylaxis against Candida infections in patients undergoing haematopoietic stem cell transplantation (HSCT) or who are expected to have neutropenia for ≥10 days. This narrative review focuses on the use of micafungin in paediatric indications approved in the EU, which may vary from those approved elsewhere in the world. Micafungin has a broad spectrum of in vitro activity against clinically relevant isolates of Candida spp. (including fluconazole-resistant Candida glabrata isolates), a low propensity for emergence of resistant isolates and a convenient once-daily regimen. In paediatric substudies and a small multinational, phase 3 trial in neonates with proven invasive candidiasis, intravenous micafungin was effective and generally well tolerated in the treatment of candidaemia and other types of invasive candidiasis and as prophylaxis against fungal infections in patients undergoing HSCT. Hence, micafungin remains an important option for the prophylaxis and treatment of invasive Candida infections in paediatric and adult patients.

Abstract
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.

Abstract
Liposomal amphotericin B (AmBisome(®); LAmB) is a unique lipid formulation of amphotericin B. LAmB is a standard of care for a wide range of medically important opportunistic fungal pathogens. LAmB has a significantly improved toxicity profile compared with conventional amphotericin B deoxycholate (DAmB). Despite nearly 20 years of clinical use, the pharmacokinetics and pharmacodynamics of this agent, which differ considerably from DAmB, remain relatively poorly understood and underutilized in the clinical setting. The molecular pharmacology, preclinical and clinical pharmacokinetics, and clinical experience with LAmB for the most commonly encountered fungal pathogens are reviewed. In vitro, experimental animal models and human clinical trial data are summarized, and novel routes of administration and dosing schedules are discussed. LAmB is a formulation that results in reduced toxicity as compared with DAmB while retaining the antifungal effect of the active agent. Its long terminal half-life and retention in tissues suggest that single or intermittent dosing regimens are feasible, and these should be actively investigated in both preclinical models and in clinical trials. Significant gaps remain in knowledge of pharmacokinetics and pharmacodynamics in special populations such as neonates and children, pregnant women and obese patients.

Abstract
Background Pediatric Candida infections are associated with worse clinical outcomes and increased costs. Yet, it is not definitively known if particular species are associated with more severe illness. Differential risk factor exposures among the species group may also exist. We aimed to determine whether certain Candida species are more strongly associated with worse outcomes, and whether certain risk factors more strongly predispose patients to infection with certain species. Methods Microbiology lab records from patients seen from 2003 to 2010 at an urban children’s hospital were reviewed for invasive or disseminated Candida infections. Data on measures of disease severity/outcome and risk factors were abstracted and analyzed to determine differences associated with various Candida species. Results Exactly 106 cases of infection were analyzed. Non-albicans species were associated with a significantly longer length of stay postdiagnosis (P=0.03), as well as longer treatment (P=0.02). Candida albicans was associated with a higher number of antihypotensive medications required (P=0.03) and length of mechanical ventilation postdiagnosis (P=0.05). Candida tropicalis was associated with the highest mortality (45.5%). Hypotension, which was found to be significantly associated with concurrent infection, was significantly associated with increased risk of mortality (odds ratio =5.85, P=0.005). Initial choice of antifungal therapy was not associated with differences in eventual patient mortality. Multivariate logistic regression modeling revealed a trend toward C. albicans infection in patients receiving antineoplastic chemotherapy and non-albicans infection in patients with >96 hours mechanical ventilation. Conclusion Interspecies differences may exist for Candida in terms of disease severity and risk factors. Underlying morbidity and the role of concurrent infections may play a key role in poor outcomes.

Abstract
Pediatric patients present with differing underlying conditions and cytotoxic therapeutic protocols, so the differing epidemiology of invasive candidiasis in children versus adults is not surprising. Understanding the Candida species epidemiology is critical, as we often begin empiric therapy or therapy before antifungal susceptibilities are known. Reports with newer molecular diagnostic assays for invasive candidiasis are rare and require more study to develop firm pediatric-specific guidance. Antifungal treatment of pediatric candidiasis is reviewed in the context of larger epidemiologic studies and the few trials completed to date.

Abstract
OBJECTIVE Rapid and effective treatment of invasive fungal infection (IFI) in patients with leukemia is important for survival. In this study, we aimed to describe variations regarding clinical features, treatment modalities, time of restarting chemotherapy, and outcome in children with IFI and acute leukemia (AL). MATERIALS AND METHODS The charts of all pediatric AL patients in our clinic between the years of 2001 and 2013 were retrospectively reviewed. All patients received prophylactic fluconazole during the chemotherapy period. RESULTS IFI was identified in 25 (14%) of 174 AL patients. Most of them were in the consolidation phase of chemotherapy and the patients had severe neutropenia. The median time between leukemia diagnosis and definition of IFI was 122 days. Twenty-four patients had pulmonary IFI. The most frequent finding on computed tomography was typical parenchymal nodules. The episodes were defined as proven in 4 (16%) patients, probable in 7 (28%) patients, and possible in 14 (56%) patients. The median time for discontinuation of chemotherapy was 27 days. IFI was treated successfully in all patients with voriconazole, amphotericin B, caspofungin, or posaconazole alone or in combination. Chemotherapy was restarted in 50% of the patients safely within 4 weeks and none of those patients experienced reactivation of IFI. All of them were given secondary prophylaxis. The median time for antifungal treatment and for secondary prophylaxis was 26 and 90 days, respectively. None of the patients died due to IFI. CONCLUSION Our data show that rapid and effective antifungal therapy with rational treatment modalities may decrease the incidence of death and that restarting chemotherapy within several weeks may be safe in children with AL and IFI.

Abstract
Pathogenic yeast forms are commonly associated with invasive fungal disease in the immunocompromised host, including patients with haematological malignancies and patients of haemopoietic stem cell transplants. Yeasts include the Candida spp., Cryptococcus spp., Pneumocystis jirovecii and some lesser-known pathogens. Candida species remain the most common cause of invasive yeast infections (and the most common human pathogenic fungi). These guidelines present evidence-based recommendations for the antifungal management of established, invasive yeast infections in adult and paediatric patients in the haematology/oncology setting. Consideration is also given to the critically ill patient in intensive care units, including the neonatal intensive care unit. Evidence for 'pre-emptive' or 'diagnostic-driven antifungal therapy' is also discussed. For the purposes of this paper, invasive yeast diseases are categorised under the headings of invasive candidiasis, cryptococcosis and uncommon yeast infections. Specific recommendations for the management of Pneumocystis jirovecii are presented in an accompanying article (see consensus guidelines by Cooley et al. appearing elsewhere in this supplement).

Abstract
Limited data are available about the safety and efficacy of micafungin in children. A postmarketing surveillance study was conducted to assess the safety and effectiveness of micafungin, an echinocandin antifungal, in pediatric patients. A prospective multicenter postmarketing observational study was carried out between October 2006 and September 2008 in Japan. Pediatric patients under 16 years received an intravenous infusion of micafungin at a dose of 1 mg/kg for candidiasis and 1 to 3 mg/kg for aspergillosis, with the option of increasing the dose if required to 6 mg/kg once daily. All adverse events were recorded. A total of 201 pediatric patients were enrolled. There were 55 adverse drug reactions reported among 42 of 190 patients evaluated for safety (22.1%); the most frequently reported adverse drug reaction was hepatobiliary disorders. No adverse drug reactions were reported in 18 neonates (aged below 4 wk). The overall clinical response rate in 91 patients evaluated for efficacy was 86.8%. The response rate in neonates was 90.0%, and there were no differences in the response rate by age. Micafungin was found to have sufficient safety and effectiveness for the treatment of fungal infections in pediatric patients with various backgrounds.

Abstract
INTRODUCTION Invasive candidiasis is responsible for ∼ 10% of nosocomial sepsis in very-low-birth-weight infants and is associated with substantial morbidity and mortality. Over the last two decades, the antifungal armamentarium against Candida spp. has increased; however, efficacy and safety studies in this population are lacking. AREAS COVERED We reviewed the medical literature and extracted information on clinical and observational studies evaluating the use of antifungal agents in neonates with invasive candidiasis. EXPERT OPINION Efficacy and safety data for antifungals in neonates are lacking, and the majority of studies conducted to date have concentrated on pharmacokinetic/pharmacodynamic evaluations. Unlike other anti-infective agents, efficacy data in the setting of neonatal candidiasis cannot be extrapolated from adult studies due to differences in the pathophysiology of the disease in this population relative to older children and adults. Data for amphotericin B deoxycholate, fluconazole, and micafungin suggest that these are the current agents of choice for this disease in neonates until data for newer antifungal agents become available. For prophylaxis, data from fluconazole randomized controlled trials will be submitted to the regulatory agencies for labeling. Ultimately, the field of therapeutics for neonatal candidiasis will require multidisciplinary collaboration given the numerous challenges associated with conducting clinical trials in neonates.

Abstract
Invasive fungal infections are a major cause of morbidity and mortality in patients with hematopoietic stem cell transplantation. A prospective multicenter post-marketing observational surveillance study was conducted from July 2007 to June 2010 to assess the safety and efficacy of micafungin, an echinocandin antifungal, for prophylaxis against invasive fungal infections in Japanese patients undergoing hematopoietic stem cell transplantation. Among 241 patients evaluated for safety, 143 adverse drug reactions were reported in 86 patients (35.7%), with hepatobiliary disorders the most frequently reported adverse drug reactions. The success rate for prophylaxis at the end of observation was 72.8% (131/180 patients), and the incidence of breakthrough infections was only 4.4% (8/180 patients). In conclusion, micafungin had sufficient safety and efficacy for prophylaxis against invasive fungal infections in Japanese patients with various backgrounds undergoing hematopoietic stem cell transplantation.

Abstract
INTRODUCTION Invasive fungal infections (IFIs) in neonatal and pediatric patients are still associated with high morbidity and mortality, increased length of hospital stay and high healthcare cost. Two key components are prerequisite to combat pediatric IFIs; first, definition of the 'at-risk' populations that could benefit the most from prophylactic treatment and second, prompt initiation of effective antifungal therapy. AREAS COVERED In this article, updated prevention and targeted therapeutic approaches for IFIs in neonates and immunocompromised children are reviewed. Furthermore, European and American guidelines concerning IFI treatment in neonates and children are compared. EXPERT OPINION IFIs in neonates and children present substantial differences from adults in respect to their epidemiology, pharmacokinetics of antifungal agents and dosing as well as absence of interventional Phase III and IV clinical trials for guidance of evidence-based decisions. In the therapeutic armamentarium of these age groups, although amphotericin B formulations remain widely indicated, azoles with broader spectrum activity as well as echinocandins have been added in the updated antifungal treatment algorithm. Recent European guidelines (ESCMID and ECIL) contain specific recommendations for pediatric patients with IFIs. In both age groups, definitive updated guidance for prophylaxis and more importantly targeted treatment need to be further evaluated by large, multicenter, randomized controlled trials.

Abstract
The aim of this analysis was to identify therapeutic micafungin regimens for children that produce the same micafungin exposures known to be effective for the prevention and treatment of Candida infections in adults. Pediatric pharmacokinetic data from 229 patients between the ages of 4 months and <17 years were obtained from four phase I and two phase III clinical trials. Population pharmacokinetic models were used to simulate the proportion of children who had a steady-state area under the concentration-time curve at 24 hours (AUC24) of micafungin within the 10th to 90th percentile range observed in a population of adults receiving a dose of micafungin with established efficacy for invasive candidiasis (100 mg/day), i.e., 75 to 139 μg·h/ml. Simulated pediatric dosages of 0.5 to 5 mg/kg of body weight/day were explored. A two-compartment model was used that incorporated body weight as a predefined covariate for allometric scaling of the pharmacokinetic parameters. During construction of the model, aspartate aminotransferase and total bilirubin were also identified as covariates that had a significant effect on micafungin clearance. A dose of 2 mg/kg resulted in the highest proportion of children within the predefined micafungin AUC24 target range for invasive candidiasis. Cutoffs of 40 or 50 kg for weight-based dosing resulted in heavier children being appropriately dosed. Thus, dose regimens of 1, 2, and 3 mg/kg/day micafungin are appropriate for the prevention of invasive candidiasis, the treatment of invasive candidiasis, and the treatment of esophageal candidiasis, respectively, in children aged 4 months to <17 years.

Abstract
Background A multicenter observational study was conducted in Italy to assess the safety of micafungin in the daily clinical practice for the treatment of proven and suspected invasive candidiasis (IC), as well as to describe rates of clinical response to micafungin treatment. Methods From October 2010 to March 2012, data from consecutive eligible neonate, pediatric, and adult patients treated with micafungin for a proven or suspected IC were collected. Patients were deemed as eligible if they or their parents signed an informed consent. The study endpoints were to assess safety of micafungin in the treatment of both proven and suspected IC, and to describe rates of clinical response to micafungin treatment. Clinical response was assessed at the end of micafungin treatment (EOMT) and defined as favorable (complete or partial resolution of signs and symptoms) or unfavorable (stability or progression). Results During the study period, 108 patients with proven or suspected IC were enrolled. Thirty-six out of 108 patients (33%) were < 18 year-old (median 1 year), whereas 72 (67%) were ≥ 18 year-old (median 71 years). Neonates in NICU accounted for 36% of pediatric patients, with the majority of them (54%) being extremely low birth weight (ELBW) newborns. Fifty-eight out of 108 patients (54%) received micafungin for a proven IC, whereas 50/108 patients (46%) were treated for a suspected IC. Among proven IC, candidemia accounted for the majority of events (54/58, 93%), with Candida albicans (35/58, 60%) as the most frequently isolated species. Therapy was discontinued due to occurrence of an adverse event in 4/108 subjects (4%). No pediatric patient had treatment interruption because of adverse events. A 67% favorable response rate was observed at EOMT. No age-, species-, underlying conditions- or ward-related differences of favorable response were observed. Survival at EOMT was 90% (97/108 patients), with rates of 97% (35/36) and 86% (62/72) among children and adults, respectively. Conclusions Micafungin was well tolerated in a heterogeneous real world population with a bimodal age distribution. A high rate of favorable response to micafungin treatment was reported in both proven and suspected IC.

Abstract
Catheter-related bloodstream infection (C-RBSI) is one of the most frequent nosocomial infections. It is associated with high rates of morbidity and mortality. Candida spp. is the third most common cause of C-RBSI after coagulase-negative staphylococci and Staphylococcus aureus and is responsible for approximately 8% of episodes. The main cause of catheter-related candidemia is the ability of some Candida strains-mainly C. albicans and C. parapsilosis-to produce biofilms. Many in vitro and in vivo models have been designed to assess the activity of antifungal drugs against Candida biofilms. Echinocandins have proven to be the most active antifungal drugs. Potential options in situations where the catheter cannot be removed include the combination of systemic and lock antifungal therapy. However, well-designed and -executed clinical trials must be performed before firm recommendations can be issued.

Abstract
Invasive fungal infections are a significant cause of morbidity and mortality in children. Successful management of these systemic infections requires identification of the causative pathogen, appropriate antifungal selection, and optimisation of its pharmacokinetic and pharmacodynamic properties to maximise its antifungal activity and minimise toxicity and the emergence of resistance. This review highlights salient scientific advancements in paediatric antifungal pharmacotherapies and focuses on pharmacokinetic and pharmacodynamic studies that underpin current clinical decision making. Four classes of drugs are widely used in the treatment of invasive fungal infections in children, including the polyenes, triazoles, pyrimidine analogues and echinocandins. Several lipidic formulations of the polyene amphotericin B have substantially reduced the toxicity associated with the traditional amphotericin B formulation. Monotherapy with the pyrimidine analogue flucytosine rapidly promotes the emergence of resistance and cannot be recommended. However, when used in combination with other antifungal agents, therapeutic drug monitoring of flucytosine has been shown to reduce high peak flucytosine concentrations, which are strongly associated with toxicity. The triazoles feature large inter-individual pharmacokinetic variability, although this pattern is less pronounced with fluconazole. In clinical trials, posaconazole was associated with fewer adverse effects than other members of the triazole family, though both posaconazole and itraconazole display erratic absorption that is influenced by gastric pH and the gastric emptying rate. Limited data suggest that the clinical response to therapy may be improved with higher plasma posaconazole and itraconazole concentrations. For voriconazole, pharmacokinetic studies among children have revealed that children require twice the recommended adult dose to achieve comparable blood concentrations. Voriconazole clearance is also affected by the cytochrome P450 (CYP) 2C19 genotype and hepatic impairment. Therapeutic drug monitoring is recommended as voriconazole pharmacokinetics are highly variable and small dose increases can result in marked changes in plasma concentrations. For the echinocandins, the primary source of pharmacokinetic variability stems from an age-dependent decrease in clearance with increasing age. Consequently, young children require larger doses per kilogram of body weight than older children and adults. Routine therapeutic drug monitoring for the echinocandins is not recommended. The effectiveness of many systemic antifungal agents has been correlated with pharmacodynamic targets in in vitro and in murine models of invasive candidiasis and aspergillosis. Further study is needed to translate these findings into optimal dosing regimens for children and to understand how these agents interact when multiple antifungal agents are used in combination.

Abstract
BACKGROUND Micafungin, an antifungal echinocandin, has been indicated for pediatric patients with invasive fungal infection (IFI) in Japan and Europe. Its efficacy in immunocompromised pediatric patients with IFI, however, has not been fully investigated. METHODS The safety and efficacy of micafungin as an antifungal therapy were analyzed in nine consecutive severe immunocompromised patients with IFI. RESULTS Three patients with proven or probable Candida infections had complete response to micafungin therapy. Of the other six patients with proven, probable or possible Aspergillus infection, four had complete response and one had partial response to micafungin treatment. No severe adverse events were observed. CONCLUSIONS In this small series, micafungin was effective for IFI caused by both Candida and Aspergillus species and no severe adverse events were observed in these immunocompromised patients.

Abstract
BACKGROUND Invasive fungal infections cause excessive morbidity and mortality in premature neonates and severely ill infants. METHODS Safety and efficacy outcomes of micafungin were compared between prematurely and non-prematurely born infants <2 years of age. Data were obtained from all completed phase I-III clinical trials with micafungin that had enrolled infants (<2 years of age) that were listed in the Astellas Clinical Study Database. Demographics, adverse events, hepatic function tests and treatment success data were extracted and validated by the Astellas biostatistical group for all micafungin-treated patients, <2 years of age, using the unique patient identifier. RESULTS One-hundred and sixteen patients included in 9 clinical trials, 48% premature [birth weight (BW) <2500 g and/or gestational age <37 weeks], 52% non-premature, received ≥ 1 dose of micafungin. Among premature patients, 14.5% were low BW (1500-2499 g), 36.4% very low BW (1000-1499 g) and 49.1% extremely low BW (<1000 g). Ninety patients (78%) completed the studies; 13 [11% (4 premature)] died. Significantly more non-premature than premature patients discontinued treatment (P = 0.003). Treatment-related adverse events were recorded in 23% of patients with no difference between groups. More extremely low BW (n = 4, 15%) and very low BW (n = 8, 40%) infants experienced treatment-related adverse events than low BW (n = 0) and there was no relation to micafungin dose or duration. For a subgroup of 30 patients with invasive candidiasis, treatment success was achieved in 73% in both premature and non-premature groups. Prophylaxis was successful in 4/5 non-premature hematopoietic stem cell transplant patients. CONCLUSION Micafungin has a safe profile in premature and non-premature infants with substantial efficacy.

Abstract
Invasive candidiasis (IC) and candidaemia are leading causes of infectious morbidity and mortality among immunocompromised paediatric patients and those admitted to intensive care units. Despite improvements in diagnosis, prevention and treatment, both mortality rates and the economic burden of disease still remain high. To address this issue, several international societies and organisations have proposed guidelines for the management of IC/candidaemia in both neonates and children. In this article, we review current recommendations of the Infectious Diseases Society of America, the European Conference on Infection in Leukaemia, the European Society of Clinical Microbiology and Infectious Diseases and the German Speaking Mycological Society/Paul-Ehrlich Society for Chemotherapy for the management and prevention of IC/candidaemia in children and neonates.

Abstract
Invasive fungal disease (IFD) remains life threatening in premature infants and immunocompromised children despite the recent development of new antifungal agents. Optimal dosing of antifungals is one of the few factors clinicians can control to improve outcomes of IFD. However, dosing in children cannot be extrapolated from adult data because IFD pathophysiology, immune response, and drug disposition differ from adults. We critically examined the literature on pharmacokinetics (PK) and pharmacodynamics (PD) of antifungal agents and highlight recent developments in treating pediatric IFD. To match adult exposure in pediatric patients, dosing adjustment is necessary for almost all antifungals. In young infants, the maturation of renal and metabolic functions occurs rapidly and can significantly influence drug exposure. Fluconazole clearance doubles from birth to 28 days of life and, beyond the neonatal period, agents such as fluconazole, voriconazole, and micafungin require higher dosing than in adults because of faster clearance in children. As a result, dosing recommendations are specific to bracketed ranges of age. PD principles of antifungals mostly rely on in vitro and in vivo models but very few PD studies specifically address IFD in children. The exposure-response relationship may differ in younger children compared with adults, especially in infants with invasive candidiasis who are at higher risk of disseminated disease and meningoencephalitis, and by extension severe neurodevelopmental impairment. Micafungin is the only antifungal agent for which a specific target of exposure was proposed based on a neonatal hematogenous Candida meningoencephalitis animal model. In this review, we found that pediatric data on drug disposition of newer triazoles and echinocandins are lacking, dosing of older antifungals such as fluconazole and amphotericin B products still need optimization in young infants, and that target PK/PD indices need to be clinically validated for almost all antifungals in children. A better understanding of age-specific PK and PD of new antifungals in infants and children will help improve clinical outcomes of IFD by informing dosing and identifying future research areas.
