Abstract
BACKGROUND/PURPOSE Invasive candidiasis is a severe infectious disease that could lead to mortality in critically ill children. METHODS We collected data regarding demographics, underlying diseases, predisposing factors, outcomes for pediatric patients with candidemia at a medical centre in Taiwan from 2011 to 2017. RESULTS Fifty-eight patients with 60 candidemia episodes were diagnosed. The 3 most common species were Candida albicans (42%), Candida parapsilosis (25%) and Candida tropicalis (23%). C. parapsilosis predominantly infected infants and neonates (median age: 0.8 years, range: 0.1-14.5). Cases with C. tropicalis had significantly higher rates of multidrug resistance (p = 0.011) and disseminated candidiasis (p = 0.025) compared with other cases. The all-cause mortality rate was 43%, and the candidemia-related mortality rate was 29%. Pediatric sequential organ failure assessment score >8 [adjusted odds ratio (aOR) 66.2, 95% CI 4.03-1088.5] and posaconazole resistance (aOR 33.57, 95% CI 1.61-700.3) were the most significant risk factors associated with candidemia-related mortality, whereas treatment with effective antifungal agents within 48 h (aOR 0.07, 95% CI 0.01-0.9) was the only significant protective factor. CONCLUSIONS Candidemia-related mortality was related to azole resistance; therefore, empirical therapy with echinocandin or amphotericin B is recommended pending species and susceptibility results.

Risk factors and clinical analysis of peripherally inserted central catheter-related fungal colonization in premature infants. Sci Rep 2021; 11:20897. [PMID: 34686686 PMCID: PMC8536761 DOI: 10.1038/s41598-021-00120-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Accepted: 09/21/2021] [Indexed: 01/12/2023] Open
Abstract
We aimed to analyze the risk factors of positive peripherally inserted central catheter (PICC)-related fungal colonization in preterm infants. This retrospective study collected data from 2018 to 2020. The enrolled infants who underwent PICC insertion were born at < 32 weeks’ gestation or birth weight < 1500 g. The demographics, PICC-related characteristics, and treatment information were collected. Univariate and multivariate analyses were performed to investigate risk factors for PICC-related fungal colonization. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off values for the duration of antibiotics and parenteral nutrition. In total, 124 premature infants underwent PICC insertion. Among them, 19 patients had positive results of fungi on the PICC tips. The duration of antibiotics (odds ratio [OR] 1.16, 95% confidence interval [CI] 1.02–1.31), parenteral nutrition infusion (OR 1.27, 95% CI 1.05–1.54), and postnatal glucocorticoid exposure (OR 9.48, 95% CI 1.06–84.98) were independent risk factors for fungal colonization in PICCs. The ROC curves showed that the risk increased after 15 days of antibiotic use and 28 days of parenteral nutrition infusion. Appropriate clinical management should be used to prevent fungal colonization and fungemia.

Abstract
INTRODUCTION A bioassay based on the detection of beta-glucan, a constituent of the cell wall of fungi, has been successfully used to diagnose fungal infections in a variety of biological fluids but not yet in the amniotic fluid. OBJECTIVE To determine the diagnostic performance of a beta-glucan bioassay in the detection of Candida species in the amniotic fluid of women who either did or did not have an intrauterine contraceptive device (IUD) in place during an episode of spontaneous preterm parturition. METHODS The study population comprised women who had a singleton pregnancy without congenital or chromosomal abnormalities, who experienced preterm labor or preterm prelabor rupture of the fetal membranes, and who underwent a transabdominal amniocentesis for clinical indications. Samples of amniotic fluid were cultured for aerobic and anaerobic bacteria, genital mycoplasmas, and Candida species, and assayed for beta-glucan, using the (1→3)-beta-d-glucan-specific Limulus amebocyte lysate test (beta-glucan assay) in all cases. Amniotic fluid interleukin (IL)-6 assay results were also available for all cases. The beta-glucan assay takes about 1 hour to run: a concentration >80 pg/mL was considered positive for fungi. Sterile intra-amniotic inflammation of the amniotic cavity was defined by the presence of an amniotic fluid IL-6 concentration ≥2.6 ng/mL and a negative amniotic fluid culture. RESULTS (1) One hundred ninety-seven (197) women met the study criteria, of whom 58 (29.4%) had an IUD in place; (2) 20 (10.2%) women had a culture of proven intra-amniotic Candida species-related infection, 19 of whom had a positive beta-glucan assay [sensitivity, 95% (19/20; 95% confidence interval (CI): 75.1-99.9%)]; and (3) the specificity of the beta-glucan assay was 75.1% [133/177; 95% CI: 68.1-99.9%]. It was affected by the presence of nonfungal intra-amniotic infections and an IUD, but not by the presence of sterile intra-amniotic inflammation, and there was a significant interaction between the presence of an IUD and nonfungal intra-amniotic infections (estimated for the interaction effect = 2.1923, p value =.026). The assay's specificity was reduced when nonfungal intra-amniotic infections were diagnosed but only in women who did not have an IUD. Among women without an IUD, the assay's specificity was 91.4% (117/128); it was 93% (106/114) for those without intra-amniotic infection, and 78.6% (11/14) for those with a nonfungal intra-amniotic infection; the difference was not significant (p = .09). Among women with an IUD, the assay's specificity was 32.7% (16/49); 42.9% (9/21) for those with a nonfungal intra-amniotic infection; and 25% (7/28) for those without intra-amniotic infection; and the difference was significant (p = .03). CONCLUSIONS The beta-glucan assay is a sensitive, rapid, point-of-care test used to diagnose intra-amniotic Candida species-related infection, and it has a high specificity in pregnant women who did not have an IUD in place.

Abstract
BACKGROUND The incidence rate of invasive candidiasis in newborns with birth weight below 1,500 g ranges from 2% to 8%, and fluconazole prophylaxis in neonatal units is recommended when the incidence of invasive candidiasis is higher than 5%. This study aimed to compare the effectiveness of targeted prophylaxis and universal prophylaxis with fluconazole in the prevention of invasive candidiasis. METHODS This was a historical cohort comparing the targeted prophylaxis for newborns weighing less than 1,500 g and the universal prophylaxis for newborns weighing less than 1,000 g. RESULTS The overall incidence rate of invasive candidiasis was 5.25% and was reduced from 7.1% to 3.72% with universal prophylaxis (p = 0.04). In a multivariate analysis, the significant factors associated with the development of candidiasis were birth weight less than 1,000 g, prolonged hospitalization, previous surgery, prolonged use of mechanical ventilation, prior exposure to antimicrobial treatments, and use of targeted prophylaxis. CONCLUSIONS Universal prophylaxis had lower incidence of invasive candidiasis, and preventive measures considering the risk factors are mandatory to reduce the incidence of invasive candidiasis.

Abstract
BACKGROUND Invasive candidiasis is an important cause of sepsis in extremely low birth weight infants (ELBW, < 1000 g), is often fatal, and frequently results in neurodevelopmental impairment (NDI) among survivors. We sought to assess the antifungal minimum inhibitory concentration (MIC) distribution for Candida in ELBW infants and evaluate the association between antifungal resistance and death or NDI. METHODS This was a secondary analysis of a National Institute of Child Health and Human Development Neonatal Research Network study. MIC values were determined for fluconazole, amphotericin B and micafungin. NDI was assessed at 18-22 months adjusted age using the Bayley Scales of Infant Development. An infant was defined as having a resistant Candida isolate if ≥ 1 positive cultures from normally sterile sites (blood, cerebrospinal fluid, or urine) were resistant to ≥ 1 antifungal agent. In addition to resistance status, we categorized fungal isolates according to MIC values (low and high). The association between death/NDI and MIC level was determined using logistic regression, controlling for gestational age and Bayley Scales of Infant Development (II or III). RESULTS Among 137 ELBW infants with IC, MICs were determined for 308 isolates from 110 (80%) infants. Three Candida isolates from 3 infants were resistant to fluconazole. None were resistant to amphotericin B or micafungin. No significant difference in death, NDI, or death/NDI between groups with low and high MICs was observed. CONCLUSIONS Antifungal resistance was rare among infecting Candida isolates, and MIC level was not associated with increased risk of death or NDI in this cohort of ELBW infants.

Abstract
OBJECTIVE This article aims to review the use of antifungal prophylaxis with intravenous fluconazole in premature newborns and the occurrence of Invasive Candidiasis. METHODS This is a systematic review with search at databases: PubMed, Capes Portal, Virtual Health Library (BVS - Biblioteca Virtual em Saúde)/Lilacs, Scopus and Cochrane. The keywords used were: "Antifungal", "Candida" "Fluconazole prophylaxis" and "Preterm infants". RESULTS Invasive Candidiasis was evaluated in all the twelve items. In eleven of them, there was a statistically significant difference between the groups receiving prophylactic fluconazole, with lower frequency of Invasive Candidiasis, compared to placebo or no prophylaxis group. Colonization by Candida species was also evaluated in five studies; four of them presented statistically lower proportion of colonization in patients with Fluconazole prophylaxis, compared to placebo or no drugs. In one study, there was a significant difference, favoring the use of fluconazole, and reduction of death. CONCLUSION Studies indicate the effectiveness of prophylaxis with fluconazole, with reduction in the incidence of colonization and invasive fungal disease. The benefits of prophylaxis should be evaluated considering the incidence of candidiasis in the unit, the mortality associated with candidiasis, the safety and toxicity of short and long-term medication, and the potential for development of resistant pathogens.

Abstract
BACKGROUND Invasive candidiasis (IC) is an important cause of sepsis in premature infants and is associated with a high risk of death and neurodevelopmental impairment. Prevention of IC has become a major focus in very low birth weight infants, with fluconazole increasingly used as prophylaxis. METHODS We identified all randomized, placebo-controlled trials evaluating fluconazole prophylaxis in premature infants conducted in the United States. We obtained patient-level data from the study investigators and performed an aggregated analysis. The occurrence of each endpoint in infants who received prophylaxis with fluconazole vs placebo was compared. Endpoints evaluated were IC or death, IC, death, Candida colonization, and fluconazole resistance among tested isolates. Safety endpoints evaluated included clinical and laboratory parameters. RESULTS Fluconazole prophylaxis reduced the odds of IC or death, IC, and Candida colonization during the drug exposure period compared with infants given placebo: odds ratios of 0.48 (95% confidence interval [CI], .30-.78), 0.20 (95% CI, .08-.51), and 0.28 (95% CI, .18-.41), respectively. The incidence of clinical and laboratory adverse events was similar for infants who received fluconazole compared with placebo. There was no statistically significant difference in the proportion of tested isolates that were resistant to fluconazole between the fluconazole and placebo groups. CONCLUSIONS Fluconazole prophylaxis is effective and safe in reducing IC and Candida colonization in premature infants, and has no impact on resistance.

Abstract
BACKGROUND The currently available evidence shows fluconazole is an effective prophylaxis treatment against invasive fungal infections in preterm neonates in neonatal intensive care units (NICUs). However, the duration and dosing of this prophylaxis treatment remain controversial. Thus, a meta-analysis and systematic review are necessary. METHODS PubMed and EMBASE were systematically searched with no restrictions. All relevant citations that compared prophylactic fluconazole and no prophylaxis were considered for inclusion. Pooled effect estimates were obtained through fixed- and random-effects meta-analyses, and a meta-regression was used to explore the sources of heterogeneity in the data. RESULTS Five independent randomized controlled clinical trials (RCTs) involving 1006 preterm neonates were identified. Compared with no prophylaxis, the overall combined relative risks (RRs) of invasive fungal infection with the 28- and 42-day durations of prophylactic fluconazole were 0.80 (95 % CI 0.48-1.35, p = 0.4048) and 0.30 (95 % CI 0.15-0.58, p = 0.0004), respectively. The fluconazole dose had no significant impact on the RR of invasive fungal infections. The RR of mortality presented no significant differences between prophylactic fluconazole and no prophylaxis (RR 0.82, 95 % CI 0.60 to 1.12, p = 0.2093). CONCLUSIONS Prophylaxis with fluconazole for 42 days was found to be superior to no prophylaxis as a strategy for preventing invasive fungal infection in preterm infants in NICUs except in terms of mortality. The dosing regimen of prophylactic fluconazole may have no impact on the outcome; however, due to the limitations of the available data, further research is needed.

Abstract
BACKGROUND Fluconazole prophylaxis (FP) in premature infants is well studied and has been shown to decrease invasive candidiasis (ICs). IC in neonates has significant financial costs; determining the cost-benefit of FP may provide additional justification for targeting high-risk neonates. We aimed to determine the IC rate in premature infants at which FP is cost-beneficial. METHODS A decision tree cost-analysis model using cost of FP related to costs associated with IC was used. We searched PubMed for all papers that used intravenous FP and reported rates of IC in very low birth weight neonates. Average IC rates in those who received FP (2.0%; range, 0-6.1%) and in those who did not receive FP (9.2%; range, 0-20.5%) were used. Incremental hospital costs because of IC and for FP were retrieved from the literature. Sensitivity analysis was performed to determine the incremental cost of FP across the range of published IC rates. RESULTS The average cost per patient attributed to IC in patients receiving FP was $785 versus $2617 in those not receiving FP. Sensitivity analysis demonstrates the rate of IC would need to be <2.8% for FP to lose its cost-benefit. In Monte Carlo simulation, targeting infants <1000 g would lead to $50,304,333 in cost savings per year in the United States. CONCLUSIONS FP provides a cost-advantage across most IC rates seen in the youngest premature infants. Using a rate of 2.8% for their individual high-risk neonatal intensive care unit patients, providers can determine if FP is cost-beneficial in determining for whom to provide IC prophylaxis.

It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. IDSA considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances.

Abstract
BACKGROUND The increasing incidence of invasive Candida infections (ICIs) in preterm infants in the neonatal intensive care unit (NICU) of Xinhua Hospital aroused our concern. We undertook a retrospective study to evaluate the efficacy of different preventive measures for ICI in preterm infants. METHODS Preterm infants with gestational age (GA) <33 weeks admitted between 2010 and 2013 were divided into 3 groups according to the preventive measures applied in different periods: the control group (CG), fluconazole group (FG), and integrated measures group (IMG). We analyzed the incidence of ICI and distribution of fungal pathogens in these 3 groups, and also evaluated the efficiency of various measures in preventing ICIs in preterm infants. RESULTS The study sample comprised 261 preterm infants born at <33 weeks GA, including 94 in the CG, 99 in the FG, and 68 in the IMG. The differences among the groups were not significant at baseline. ICI developed in 41 of the 261 infants (15.7%). The incidence of ICI varied significantly among the groups: 22.3% in the CG (21/94), 18.2% in the FG (18/99), and only 2.9% in the IMG (2/68) (P = .003). ICI was less frequent in the IMG compared with the CG (P <.001) and the FG (P = .003). CONCLUSIONS The integrated measures approach is meaningful for the prevention of ICIs in preterm infants in NICUs with many patients but inadequate medical resources in some developing countries.

Manipulation of Host Diet To Reduce Gastrointestinal Colonization by the Opportunistic Pathogen Candida albicans. mSphere 2015; 1:mSphere00020-15.

Abstract
Candida albicans, the most common human fungal pathogen, can cause infections with a mortality rate of ~40%. C. albicans is part of the normal gut flora, but when a patient’s immune system is compromised, it can leave the gut and cause infections. By reducing the amount of C. albicans in the gut of susceptible patients, infections (and the resulting fatalities) can be prevented. Currently, this is done using antimicrobial drugs; to “preserve” drugs for treating infections, we looked for a dietary change to reduce the amount of C. albicans in the gut. Using a mouse model, we showed that adding coconut oil to the diet could become the first drug-free way to reduce C. albicans in the gut. More broadly, this model lets us study the interactions between our diet and the microbes in our body and the reasons why some of those microbes, under certain conditions, cause disease. Candida albicans, the most common human fungal pathogen, can cause systemic infections with a mortality rate of ~40%. Infections arise from colonization of the gastrointestinal (GI) tract, where C. albicans is part of the normal microflora. Reducing colonization in at-risk patients using antifungal drugs prevents C. albicans-associated mortalities. C. albicans provides a clinically relevant system for studying the relationship between diet and the microbiota as it relates to commensalism and pathogenicity. As a first step toward a dietary intervention to reduce C. albicans GI colonization, we investigated the impact of dietary lipids on murine colonization by C. albicans. Coconut oil and its constituent fatty acids have antifungal activity in vitro; we hypothesized that dietary coconut oil would reduce GI colonization by C. albicans. Colonization was lower in mice fed a coconut oil-rich diet than in mice fed diets rich in beef tallow or soybean oil. Switching beef tallow-fed mice to a coconut oil diet reduced preexisting colonization. Coconut oil reduced colonization even when the diet also contained beef tallow. Dietary coconut oil also altered the metabolic program of colonizing C. albicans cells. Long-chain fatty acids were less abundant in the cecal contents of coconut oil-fed mice than in the cecal contents of beef tallow-fed mice; the expression of genes involved in fatty acid utilization was lower in C. albicans from coconut oil-fed mice than in C. albicans from beef tallow-fed mice. Extrapolating to humans, these findings suggest that coconut oil could become the first dietary intervention to reduce C. albicans GI colonization.

Abstract
BACKGROUND Invasive fungal infection is an important cause of mortality and morbidity in very preterm and very low birth weight infants. Early diagnosis is difficult and treatment is often delayed. Systemically absorbed antifungal agents (usually azoles) are increasingly used as prophylaxis against invasive fungal infection in this population. OBJECTIVES To assess the effect of prophylactic systemic antifungal therapy on mortality and morbidity in very preterm or very low birth weight infants. SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2015, Issue 8), MEDLINE, EMBASE, and CINAHL (to May 2015), conference proceedings, and previous reviews. SELECTION CRITERIA Randomised controlled trials or quasi-randomised controlled trials that compared the effect of prophylactic systemic antifungal therapy versus placebo or no drug or another antifungal agent or dose regimen in very low birth weight infants. DATA COLLECTION AND ANALYSIS We extracted data using the standard methods of the Cochrane Neonatal Review Group, with separate evaluation of trial quality and data extraction by two review authors. MAIN RESULTS We identified 15 eligible trials enrolling a total of 1690 infants. Ten trials (1371 infants) compared systemic antifungal prophylaxis versus placebo or no drug. These trials were generally of good methodological quality. Meta-analysis found a statistically significant reduction in the incidence of invasive fungal infection (typical risk ratio (RR) 0.43, 95% confidence interval (CI) 0.31 to 0.59; risk difference (RD) -0.09, 95% CI -0.12 to -0.06). The average incidence of invasive fungal infection in the control groups of the trials (16%) was much higher than that generally reported from large cohort studies. Meta-analysis did not find a statistically significant difference in the risk of death prior to hospital discharge (typical RR 0.79, 95% CI 0.61 to 1.02; typical RD -0.04, 95% CI -0.07 to 0.00). Very limited data on long-term neurodevelopmental outcomes were available. Three trials that compared systemic versus oral or topical non-absorbed antifungal prophylaxis did not detect any statistically significant effects on invasive fungal infection or mortality. Two trials that compared different dose regimens of prophylactic intravenous fluconazole did not detect any significant differences in infection rates or mortality. AUTHORS' CONCLUSIONS Prophylactic systemic antifungal therapy reduces the incidence of invasive fungal infection in very preterm or very low birth weight infants. This finding should be interpreted and applied cautiously since the incidence of invasive fungal infection was very high in the control groups of many of the included trials. Meta-analysis does not demonstrate a statistically significant effect on mortality. There are currently only limited data on the long-term neurodevelopmental consequences for infants exposed to this intervention. In addition, there is a need for further data on the effect of the intervention on the emergence of organisms with antifungal resistance.

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
PURPOSE OF REVIEW Invasive candidiasis is a serious infection in hospitalized infants that results in significant mortality and morbidity. Fluconazole is approved by the US Food and Drug Administration for prophylaxis of invasive candidiasis in patients undergoing bone marrow transplantation but is not approved for use in infants. This review will describe the history of fluconazole use for prophylaxis in infants. RECENT FINDINGS Limiting fluconazole prophylaxis to infants with risk factors, in addition to low birth weight and early gestational age, reduces the number of infants treated with fluconazole and the duration of fluconazole therapy for each infant. SUMMARY Fluconazole prophylaxis appears to be well tolerated for use in premature infants. Reduction in the incidence of invasive candidiasis is observed even when prophylaxis is limited to infants with multiple risk factors. Centers with a low incidence of invasive candidiasis may not benefit from fluconazole prophylaxis. Significant short-term and long-term toxicity and increases in fluconazole-resistant organisms have not been observed with fluconazole use in the intensive care nursery.

Abstract
BACKGROUND Premature infants are at high risk of developing invasive candidal infections (ICI). We investigated maternal and perinatal risk factors for ICI that may help in defining at-risk infants, allowing more targeted antifungal prophylaxis to prevent morbidity and mortality. METHODS Maternal and neonatal data from infants with a birthweight between 500 and 1250 g admitted across 95 neonatal intenisve care units were analyzed for risk factors for ICI. RESULTS Data from 1890 infants were analyzed, 78 of whom had ICI. Overall mortality was 20.5% for all cases of ICI, 18.8% with candidemia, 17.2% with candiduria, and 75% when Candida was isolated in both the blood and urine. Birthweight, gestational age, male sex, and vaginal delivery were predictors of infection on univariate analysis. After logistic regression, gestational age (P < .01) and male sex (P < .01) remained significant. Vaginal birth and receiving antibiotics during the first week of life increased the risk for ICI in the 22-25 weeks' and 26-28 weeks' gestation subgroups. CONCLUSIONS Gestational age and male gender are risk factors for the development of ICI, whereas vaginal delivery and antibiotics during the first week further increase the incidence in the more premature infants. Knowing maternal and perinatal risk factors for ICI allows more targeted antifungal prophylaxis in at-risk infants.

Abstract
OBJECTIVE Neonatal invasive candidiasis is associated with significant morbidity and mortality. We describe the association between invasive candidiasis and changes in use of antifungal prophylaxis, empirical antifungal therapy, and broad-spectrum antibacterial antibiotics over time. METHODS We examined data from 709,325 infants at 322 NICUs managed by the Pediatrix Medical Group from 1997 to 2010. We determined the cumulative incidence of invasive candidiasis and use of antifungal prophylaxis, broad-spectrum antibacterial antibiotics, and empirical antifungal therapy by year. RESULTS We identified 2063 (0.3%) infants with 2101 episodes of invasive candidiasis. Over the study period, the annual incidence of invasive candidiasis decreased from 3.6 episodes per 1000 patients to 1.4 episodes per 1000 patients among all infants, from 24.2 to 11.6 episodes per 1000 patients among infants with a birth weight of 750-999 g, and from 82.7 to 23.8 episodes per 1000 patients among infants with a birth weight <750 g. Fluconazole prophylaxis use increased among all infants with a birth weight <1000 g (or <1500 g), with the largest effect on birth weights <750 g, increasing from 3.8 per 1000 patients in 1997 to 110.6 per 1000 patients in 2010. The use of broad-spectrum antibacterial antibiotics decreased among all infants from 275.7 per 1000 patients in 1997 to 48.5 per 1000 patients in 2010. The use of empirical antifungal therapy increased over time from 4.0 per 1000 patients in 1997 to 11.5 per 1000 patients in 2010. CONCLUSIONS The incidence of invasive candidiasis in the NICU decreased over the 14-year study period. Increased use of fluconazole prophylaxis and empirical antifungal therapy, along with decreased use of broad-spectrum antibacterial antibiotics, may have contributed to this observation.

Abstract
Candidemia is one of the most frequent opportunistic mycoses worldwide. Limited epidemiological studies in Latin America indicate that incidence rates are higher in this region than in the Northern Hemisphere. Diagnosis is often made late in the infection, affecting the initiation of antifungal therapy. A more scientific approach, based on specific parameters, for diagnosis and management of candidemia in Latin America is warranted. 'Recommendations for the diagnosis and management of candidemia' are a series of manuscripts that have been developed by members of the Latin America Invasive Mycosis Network. They aim to provide a set of best-evidence recommendations for the diagnosis and management of candidemia. This publication, 'Recommendations for the management of candidemia in neonates in Latin America', was written to provide guidance to healthcare professionals on the management of neonates who have, or who are at risk of, candidemia. Computerized searches of existing literature were performed by PubMed. The data were extensively reviewed and analyzed by members of the group. The group also met on two occasions to pose questions, discuss conflicting views, and deliberate on a series of management recommendations. 'Recommendations for the management of candidemia in neonates in Latin America' includes prophylaxis, empirical therapy, therapy for proven candidemia, patient work-up following diagnosis of candidemia, central venous catheter management, and management of complications. This manuscript is the fourth of this series that deals with diagnosis and treatment of invasive candidiasis.

Abstract
PURPOSE To determine the safety of fluconazole in neonates and other paediatric age groups by identifying adverse events (AEs) and drug interactions associated with treatment. METHODS A search of EMBASE (1950-January 2012), MEDLINE (1946-January 2012), the Cochrane database for systematic reviews and the Cumulative Index to Nursing and Allied Health Literature (1982-2012) for any clinical study about fluconazole use that involved at least one paediatric patient (≤17 years) was performed. Only articles with sufficient quality of safety reporting after patients' exposure to fluconazole were included. RESULTS We identified 90 articles, reporting on 4,209 patients, which met our inclusion criteria. In total, 794 AEs from 35 studies were recorded, with hepatotoxicity accounting for 378 (47.6 %) of all AEs. When fluconazole was compared with placebo and other antifungals, the relative risk (RR) of hepatotoxicity was not statistically different [RR 1.36, 95 % confidence interval (CI) 0.87-2.14, P = 0.175 and RR 1.43, 95 % CI 0.67-3.03, P = 0.352, respectively]. Complete resolution of hepatoxicity was achieved by 84 % of patients with follow-up available. There was no statistical difference in the risk of gastrointestinal events of fluconazole compared with placebo and other antifungals (RR 0.81, 95 % CI 0.12-5.60, P = 0.831 and RR 1.23, 95 %CI 0.87-1.71, P = 0.235, respectively). There were 41 drug withdrawals, 17 (42 %) of which were due to elevated liver enzymes. Five reports of drug interactions occurred in children. CONCLUSION Fluconazole is relatively safe for paediatric patients. Hepatotoxicity and gastrointestinal toxicity are the most common adverse events. It is important to be aware that drug interactions with fluconazole can result in significant toxicity.

Abstract
BACKGROUND Candida is the third most common cause of late-onset neonatal sepsis in infants born at <1500 g. Candida parapsilosis infections are increasingly reported in preterm neonates in association with indwelling catheters. METHODS We systematically reviewed neonatal literature and synthesized data pertaining to percentage of C. parapsilosis infections and mortality by meta-analyses. We also reviewed risk factors, virulence determinants, antimicrobial susceptibility patterns and outlined clinical management strategies. RESULTS C. parapsilosis infections comprised 33.47% (95% confidence interval [CI]: 30.02, 37.31) of all neonatal Candida infections. C. parapsilosis rates were similar in studies performed before the year 2000, 33.53% (95% CI: 30.06, 37.40) (28 studies), to those after 2000, 27.00% (95% CI: 8.25, 88.37) (8 studies). The mortality due to neonatal C. parapsilosis infections was 10.02% (95% CI: 7.66, 13.12). Geographical variations in C. parapsilosis infections included a low incidence in Europe and higher incidence in North America and Australia. Biofilm formation was a significant virulence determinant and predominant risk factors for C. parapsilosis infections were prematurity, prior colonization and catheterization. Amphotericin B remains the antifungal drug of choice and combination therapy with caspofungin or other echinocandins may be considered in resistant cases. CONCLUSION C. parapsilosis is a significant neonatal pathogen, comprises a third of all Candida infections and is associated with 10% mortality. Availability of tools for genetic manipulation of this organism will identify virulence determinants and organism characteristics that may explain predilection for preterm neonates. Strategies to prevent horizontal transmission in the neonatal unit are paramount in decreasing infection rates.

Abstract
BACKGROUND Invasive fungal infection is an important cause of mortality and morbidity in very low birth weight infants. Early diagnosis is difficult and treatment is often delayed. Systemic antifungal agents (usually azoles) are increasingly used as prophylaxis against invasive fungal infection. OBJECTIVES To assess the effect of prophylactic systemic antifungal therapy on mortality and morbidity in very low birth weight infants. SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 3), MEDLINE, EMBASE, and CINAHL (to August 2012), conference proceedings, and previous reviews. SELECTION CRITERIA Randomised controlled trials or quasi-randomised controlled trials that compared the effect of prophylactic systemic antifungal therapy versus placebo or no drug or another antifungal agent or dose regimen in very low birth weight infants. DATA COLLECTION AND ANALYSIS We extracted data using the standard methods of the Cochrane Neonatal Review Group, with separate evaluation of trial quality and data extraction by two review authors. MAIN RESULTS We identified 11 eligible trials enrolling a total of 1136 infants. Seven trials (involving 880 infants) compared systemic antifungal prophylaxis versus placebo or no drug. These trials were generally small but of good methodological quality. Meta-analysis found a statistically significant reduction in the incidence of invasive fungal infection in infants who received systemic antifungal prophylaxis (typical risk ratio (RR) 0.41, 95% confidence interval (CI) 0.27 to 0.61; risk difference (RD) -0.09, 95% CI -0.14 to -0.05). The average incidence of invasive fungal infection in the control groups of the trials (16%) was much higher than that generally reported from large cohort studies (< 5%). Meta-analysis did not find a statistically significant difference in the risk of death prior to hospital discharge (typical RR 0.74, 95% CI 0.52 to 1.05; RD -0.04, 95% CI -0.08 to 0.01). Very limited data on long-term neurodevelopmental outcomes were available. Two trials that compared systemic versus oral or topical non-absorbed antifungal prophylaxis did not detect any statistically significant effects on invasive fungal infection or mortality. Two trials that compared different dose regimens of prophylactic intravenous fluconazole did not detect any significant differences in infection rates or mortality. AUTHORS' CONCLUSIONS Prophylactic systemic antifungal therapy reduces the incidence of invasive fungal infection in very low birth weight infants. This finding should be interpreted and applied cautiously since the incidence of invasive fungal infection was very high in the control groups of most of the included trials. Meta-analysis does not demonstrate a statistically significant effect on mortality. There are currently only limited data on the long-term neurodevelopmental consequences for infants exposed to this intervention. In addition, there is a need for further data on the effect of the intervention on the emergence of organisms with antifungal resistance.

Abstract
Invasive candidiasis (IC) is a leading cause of morbidity and mortality in preterm infants. Even if successfully treated, IC can cause significant neurodevelopmental impairment. Preterm infants are at increased risk for hematogenous Candida meningoencephalitis owing to increased permeability of the blood-brain barrier, so antifungal treatment should have adequate central nervous system penetration. Amphotericin B deoxycholate, lipid preparations of amphotericin B, fluconazole, and micafungin are first-line treatments of IC. Fluconazole prophylaxis reduces the incidence of IC in extremely premature infants, but its safety has not been established for this indication, and as yet, the product has not been shown to reduce mortality in neonates. Targeted prophylaxis may have a role in reducing the burden of disease in this vulnerable population.

Abstract
Antifungal prophylaxis is increasingly used in very low birth weight (VLBW) infants who are at risk for severe fungal infections. Our objective was to assess the effectiveness of targeted fluconazole prophylaxis for high-risk VLBW infants. A retrospective cohort study with historical controls was performed. During the period 2007-2008, all high-risk VLBW infants (birth weight, ≤1,000 g; gestational age, ≤28 weeks; seven antimicrobial therapy or additional risk factors present) received fluconazole prophylaxis until risk factors were not present. Treated infants were compared to a gestational age- and birth weight-matched untreated cohort. Statistical analyses used univariate and multivariate analyses. The main outcome variable was a breakthrough fungal bloodstream infection (BSI). The prophylaxis cohort of 130 VLBW infants was compared to 319 control infants. The rate of fungal infections was significantly lower in the fluconazole prophylaxis group (1 of 130 vs. 19 of 319, p = 0.016); however, they did not differ in mortality (16.2 vs. 15 %, p = 0.77) or complications of prematurity. Fluconazole prophylaxis was associated with a significant decrease in candidal BSI (odds ratio, 0.05; 95 % confidence interval, 0.005-0.523). Selective vs. nonselective prophylaxis reduced the number of infants treated from 247 to 130. Conclusion Targeted fluconazole prophylaxis in VLBW infants is effective in preventing fungal infections without increasing the risk of BSI among low-risk infants.

Abstract
AIM To review the use of antifungal chemoprophylaxis to prevent neonatal invasive fungal infections (IFI) in very low birthweight infants (VLBW <1500 g). METHOD Systematic review of randomised controlled trials. RESULTS Nine trials were identified (2029 infants), with six comparing fluconazole with placebo/no treatment (840 infants), three comparing nystatin with placebo/no treatment (1200 infants) and two comparing fluconazole and nystatin (257 infants). Prophylactic fluconazole reduced the incidence of IFI in VLBW infants <1500 g to 5.1% compared with 16.0% in infants receiving placebo, relative risk (RR) = 0.36 (95% confidence interval 0.15-0.89). The mortality was 10.9% and 16.7%, respectively (RR 0.76, 0.54-1.08). Oral nystatin reduced the incidence of IFI in VLBW infants to 5.3% compared with 28.0% in infants receiving placebo (RR 0.16, 0.11-0.23). Mortality was 7.5% with nystatin and 10.9% with placebo (RR 0.86, 0.59-1.26). The incidence of IFI in studies comparing fluconazole and nystatin was 3.6% and 8.0%, respectively (RR 0.54, 0.19-1.56), and mortality was not significantly different: 4.6% versus 9.8% (RR 0.43, 0-4.31) CONCLUSIONS Prophylactic fluconazole and oral nystatin are both highly effective in preventing IFI in VLBW infants. Both agents are safe without significant toxicities. Antifungal prophylaxis should therefore be used in all VLBW infants. Given the paucity of data comparing fluconazole with nystatin, the choice of antifungal agent should be influenced by the incidence of IFI, local epidemiology and relative cost.

Abstract
OBJECTIVE To review the efficacy and safety of antifungal prophylaxis in the neonatal intensive care setting. DATA SOURCES English-language literature was accessed using MEDLINE (January 1988- December 2010). The following Medical Subject Heading (MeSH) search terms were used: "amphotericin B," "fluconazole," "nystatin," "itraconazole," "caspofungin," "voriconazole," "Candida," "prevention and control," and "critically ill." Literature was further limited to studies focusing on patient birth to 6 months of age. Abstracts and original research articles were included. Preference was given to published controlled trials. Articles providing descriptions of the safety and effectiveness of antifungal prophylaxis in neonatal intensive care patients were also used in this review. RESULTS Twenty-two studies have evaluated the impact of antifungal prophylaxis on Candida colonization or invasive infections in the Neonatal Intensive Care Unit (NICU). The two antifungal agents most commonly studied were nystatin and fluconazole. All of the nystatin studies demonstrated that nystatin is effective at reducing fungal colonization and invasive fungal infections. All of the studies designed to evaluate the impact of fluconazole prophylaxis on fungal colonization demonstrated a reduction in the incidence of fungal colonization with fluconazole prophylaxis. A total of 12 of 16 studies that evaluated the impact of fluconazole prophylaxis on the incidence of invasive fungal infections demonstrated a reduction in invasive fungal infections with fluconazole prophylaxis. Two studies found no difference between fluconazole and nystatin when used for prophylaxis. CONCLUSION Antifungal prophylaxis appears to be effective in reducing the incidence of Candida colonization and invasive Candida infections in the NICU. Antifungal prophylaxis also appears to be safe in the NICU population. The impact of antifungal prophylaxis on resistance patterns could be significant and needs to be evaluated long term before widespread prophylaxis can be recommended.

Abstract
OBJECTIVES To assess trends in incidence of Candida spp. central line-associated bloodstream infections (CLABSIs) in US NICUs, 1999-2009. METHODS Data from NICUs participating in the National Nosocomial Infections Surveillance (1999-2004) and National Healthcare Safety Network (2006-2009) were analyzed. Overall and birth weight-specific incidence rates of Candida spp. CLABSIs per 1000 central line-days were calculated. Trends in incidence were assessed by using Poisson regression, and trends in proportion of CLABSIs identified as Candida albicans were assessed by using weighted-linear regression. RESULTS Overall, 398 NICUs reported 1407 Candida spp. CLABSIs (706 due to C albicans) among 1400 neonates. Of the 1400 neonates, 963 (69%) were ≤ 1000 g at the time of birth, and 182 (13%) died. From 1999 to 2009, the overall incidence decreased significantly for CLABSIs due to Candida spp. (0.92 vs 0.2), C albicans (0.53 vs 0.09), and non-albicans Candida spp. (0.39 vs 0.1). Birth weight-specific incidence significantly decreased across all birth weight categories for C albicans. For CLABSIs due to non-albicans Candida spp., significant decreases were detected among all birth weight categories, except among neonates 1501 to 2500 g. The proportion of Candida spp. CLABSIs due to C albicans did not significantly change over time, remaining at ~50%. CONCLUSIONS Incidence of Candida spp. CLABSIs decreased substantially among NICU patients, regardless of birth weight. Decreases in incidence across all birth weight categories, and not only among neonates ≤ 1000 g in whom antifungal prophylaxis may be more common, suggest that multiple factors contributed to the declining incidence.

Abstract
Prevention of invasive Candida infections (ICI) is an achievable goal for every NICU and supported by A-1 evidence. Due to the incidence of ICI, high infection-associated mortality and neurodevelopmental impairment, antifungal prophylaxis should be targeted to infants <1000 g or ≤ 27 weeks gestation. There is A-1 evidence for both fluconazole and nystatin prophylaxis for the prevention of ICI. Evidence currently would favour fluconazole prophylaxis in high-risk preterm infants since intravenous fluconazole prophylaxis has greater efficacy compared to enteral nystatin prophylaxis, efficacy in the most immature patients in whom mortality is the highest, requires less dosing, and can be given to infants with gastrointestinal disease or haemodynamic instability. All NICUs caring for extremely preterm infants should use antifungal prophylaxis. Even in NICUs with low rates of ICI, antifungal prophylaxis is crucial to improving survival and neurodevelopmental outcomes for this vulnerable population. For infants 1000-1500 g if there is concern for ICI in the NICU, either drug could be chosen for prophylaxis. Fluconazole prophylaxis administered at 3 mg/kg twice a week, while intravenous access is required, appears to be the safest and most effective schedule in preventing ICI while attenuating the emergence of fungal resistance. Invasive Candida infections are one group of infections we can prevent.

Abstract
Invasive fungal infections represent the third-leading cause of late-onset sepsis in very-low-birth-weight infants (VLBWI) and have a high rate of infection-associated mortality. The infants at high risk for fungal sepsis are VLBWI with presence of additional risk factors that contribute to increased colonization and concentration of fungal organisms. Colonization with Candida spp. in neonates is secondary to either maternal vertical transmission or nosocomial acquisition in the nursery. Multiple sites may become colonized and a direct correlation between fungal colonization and subsequent progression to invasive candidemia was determined. Randomized, single and multiple-center, placebo-controlled trials found intravenous fluconazole prophylaxis to be effective in decreasing fungal colonization and sepsis for at-risk preterm infants <1500 g birth weight. The prophylactic use of fluconazole was found to be safe with no significant development of fungal resistance. Fluconazole prophylaxis administered to preterm neonates with birth weight <1000 g and/or 27 weeks' gestation or less has the potential of reducing and potentially eliminating invasive fungal infections and Candida-related mortality.

Abstract
OBJECTIVE The objective of this study was to evaluate the efficacy of targeted intermittent fluconazole prophylaxis (FP) to high-risk preterm (PT) infants. STUDY DESIGN Observational pre-post cohort study (n=524). Targeted FP (3 mg kg(-1)) was administered to PT infants (birth weights <1500 g and <6 weeks of age) who received broad-spectrum antibiotics for more than 2 days and had at least one additional risk factor for invasive candidiasis during the antibiotic administration period. RESULT Invasive candidiasis decreased significantly from 15.3 to 6.2% during the FP period. Duration of parenteral nutrition (15.5 vs 19.2 days), central line (12.7 vs 15.8 days) and necrotizing enterocolitis rates (7 vs 9.5%) were significantly higher in the FP period. FP was administered to 89 (31.3%) infants; the median (range) number of doses was four (1 to 24) and duration was 7 (1 to 38) days. CONCLUSION In the current study, targeted intermittent FP to a selected population of PT infants was efficacious in reducing the rate of invasive candidiasis, compared with historical controls.

Abstract
UNLABELLED Neonatal fungal infections are associated with substantial mortality and morbidity. Although prophylactic use of several antifungals has been proposed, this practice remains controversial. In order to evaluate the use of fluconazole prophylaxis in European NICUs, we conducted a cross-sectional survey by means of a structured questionnaire that was sent to European level II and III neonatal intensive care units, over a 9-month period, as part of a neonatal research FP7 European project. A total of 193 questionnaires from 28 countries were analysed. Use of antifungal prophylaxis was reported by 55% of the responders, and the most frequently used antifungal agent was fluconazole (92%). Main indications for prophylaxis were low gestational age (<28 weeks) and birth weight (<1,000 g). A dose of 3 mg/kg was used in 66% of NICUs using fluconazole, with an administration interval of 72 h in 52% of them. All responders acknowledged the need for additional trials on the efficacy of prophylactic fluconazole. Non-users of fluconazole prophylaxis were more likely to be influenced by the local incidence of candidiasis, the risk of increasing antifungal resistance and the absence of specific recommendations by paediatric societies. CONCLUSIONS Major concerns about the use of fluconazole prophylaxis include its efficacy, the risk of emergence of resistant species and the absence of clear consensus to support routine use. Future studies that address these issues will contribute to a more rational use of fluconazole prophylaxis.

Abstract
The host factors that contribute to the increased susceptibility of preterm neonates to invasive candidiasis have not been fully identified. In addition, there has been a lack of suitable models to study this problem. We show that rat pups, similar to premature neonates, display increased susceptibility to experimental Candida albicans infection. Further, we find that both C. albicans and Candida parapsilosis lipase disruptant mutants exhibit decreased virulence in rat pups, demonstrating the utility of the model to evaluate the impact of specific genes in disease pathogenesis. Our findings highlight the contribution of lipases to the virulence of C. albicans and C. parapsilosis and provide a new system to study the increased susceptibility of neonates to Candida infections.

Abstract
IN NEONATOLOGY, EVIDENCE-BASED practice (EBP) relies on well-designed, adequately powered trials to guide practitioners. Several large randomized controlled trials (RCTs) have been conducted to explore the use of fluconazole for fungal prophylaxis in premature infants. Despite the findings of these studies, practice varies among units. In a recent survey of members of the American Academy of Pediatrics (AAP), 34 percent of clinicians indicated that they have used antifungal prophylaxis and only 11 percent of clinicians indicated that a written protocol was in place in their NICU. Intravenous (IV) fluconazole (66 percent), oral nystatin (59 percent), and IV amphotericin (21 percent) were the three most commonly used agents among the respondents.1.

Abstract
Systemic fungal infections are associated with substantial case-morbidity and fatality rates in premature infants. Considerable evidence indicates that prophylaxis with fluconazole given to premature infants reduces the risk of invasive fungal infection. There is scant information from developing countries. A comparative study of 2 years, one with fluconazole prophylaxis and the other without was conducted in all premature babies weighing less than 1250 g at birth. Fluconazole was administered in 3 mg/kg doses, given every 48 hours, starting on day 3 of life, for a period of 6 weeks. Documented systemic Candida infection was the primary outcome. A total of 271 and 252 patients, respectively, were evaluated during the year before (control group) and after (treatment group) routine fluconazole prophylaxis. The control group developed 21 Candida infections (7.7%) while the treatment group had only 3 Candida infections (1.1%). This difference was statistically significant (P = 0.007; odds ratio, 0.13; 95% confidence interval, 0.03-0.47). The number needed to treat to prevent one case was 7. Although case-fatality rates for documented Candida infection were similar in both periods (76% vs. 67%), fewer deaths attributed to the fungal infection were noted in the prophylaxis year (6% vs. 1%, P = 0.003). Routine fluconazole prophylaxis given to premature infants of less than 1250 g at birth is associated with a significant impact on frequency of documented systemic Candida infections.

Abstract
The highest incidence of invasive candidal infection (ICI) occurs in extremely preterm infants (<1000 g birth weight and <or=27 weeks' gestation). In this population, ICI has high mortality, leads to significant neurodevelopmental impairment, and results in increased length of hospital stay and costs. Randomized clinical trials in infants of less than 1000 g birth weight have demonstrated that ICI is decreased 88% by antifungal prophylaxis with fluconazole compared to 54% by nystatin prophylaxis from retrospective studies. Fluconazole is more efficacious than nystatin prophylaxis in infants weighing less than 1000 g, is less expense, requires less frequent dosing (twice weekly intravenous [IV] dosing), and can be given when infants are not feeding. While antifungal prophylaxis is inexpensive, cost-effective, and easy to administer, yet has not been instituted universally despite A-1 evidence from single and multicenter studies demonstrating efficacy and safety. Debate is ongoing over whether empiric therapy or improved infection control practices are superior to prophylaxis, whether prophylaxis should be instituted only in neonatal intensive care units (NICUs) with a relatively high ICI rate, and whether fluconazole prophylaxis is safe or risks emergence of resistance. To date, azole resistance has not emerged with targeted treatment of high-risk infants for the duration of IV catheter use. Empiric therapy for suspected ICI and standardized therapy for candidemia, including central venous catheter removal, may decrease mortality; however, these approaches still risk neurodevelopmental impairment in ICI survivors. Infection control practices have not been subjected to prospective or randomized trials to demonstrate efficacy in reducing fungal infections. Evidence is presented in this article from clinical trials demonstrating efficacy and safety of antifungal prophylaxis in preventing ICI in preterm infants. The greatest impact of antifungal prophylaxis preventing ICI and decreasing Candida-related mortality and neurodevelopmental impairment would be achieved with a universal approach in all NICUs.

Abstract
In an era of quality improvement and 'getting to zero (infections and/or related mortality),' neonatal candidiasis is ripe for evidence-based initiatives. Knowledge of each institution's invasive Candida infection (ICI) incidence and infection-related mortality is critical to evaluate disease burden and effective interventions. Evidenced-based interventions include: antifungal prophylaxis, starting with appropriate dosing, and prompt removal of central venous catheters (CVC). There is A-I evidence supporting antifungal prophylaxis with fluconazole, and it should be considered in every neonatal intensive care unit (NICU). The literature supports targeting infants <1000 g and/or <or=27 weeks, because this group has high infection-related mortality and neurodevelopmental impairment in 57% of survivors. Antifungal prophylaxis has been shown to nearly eliminate infection-related mortality. Interventions start with prenatal initiatives, with women being treated for vaginal candidiasis, especially with preterm labor or complications. Targeting modifiable risk factors, including restriction policies for use of third- and fourth-generation cephalosporins, carbapenems, H2-antagonists, proton pump inhibitors, and postnatal steroids; guidelines for CVC care and removal; and feeding practices, with promotion of early feedings and breast milk, may also reduce risk. A few studies have emerged on empiric antifungal therapy with sepsis evaluations for preterm infants <1500 g and other high-risk patients that have shown favorable effects of eliminating mortality, but these have not been compared to appropriate antifungal therapy and central line removal. Further study of empiric therapy, prospective treatment studies with higher targeted dosing of amphotericin B preparations, fluconazole, and new antifungals with prompt CVC removal may contribute to a 100% survival rate for those infants >1000 g and >or=28 weeks not receiving antifungal prophylaxis. Evaluation of ICI incidence and mortality by gestational age and birth week should be followed in each NICU, to evaluate infection control and prevention.

Abstract
Recent years have witnessed a renewed interest in reducing hospital-acquired infections in critically ill patients. We review three recently tested strategies to decrease nosocomial infections specifically in the neonatal intensive care unit. These include improvement of hand hygiene, the incorporation of hand-hygiene practices into broader care bundles, and the prophylactic administration of antimicrobials, especially fluconazole, to infants at high risk prior to the onset of infection. The effectiveness of the first two interventions is well supported, particularly in older patient populations, while the effectiveness of the third is counterbalanced by the threat of the emergence of resistant-organism infections.

Abstract
BACKGROUND Invasive fungal infections (IFI) are an important cause of late-onset disease in extremely low birth weight (ELBW) infants. Despite prior trials of fluconazole prophylaxis in neonates, application of this regimen remains controversial. Review of our neonatal intensive care unit aggregate annual number of fungal isolates from sterile sites in ELBW infants from 1997 to 2006 suggested a significant decrease following the institution of routine prophylactic fluconazole in February 2002. We undertook a retrospective study to document the efficacy and adverse effects of routine fluconazole prophylaxis. METHODS ELBW infants admitted during 2000 to 2006 were divided into 2 groups: Control group-admitted before the institution of fluconazole prophylaxis, and Fluconazole group-admitted after institution of fluconazole prophylaxis. Primary outcome was the frequency of IFI. Secondary outcome was the frequency of cholestasis, which has been rarely reported with fluconazole use. RESULTS Data were extracted from 262 infant records: control 99, fluconazole 163. Baseline demographics and potentially confounding variables differed between the 2 groups with greater birth weight, greater gestational age, shorter durations of ventilation and central catheter use, and earlier start of feeding in the control group, reflecting healthier control infants. Frequency of IFI was 7.1% in the control group versus 1.8% in the fluconazole group, P = 0.045. Logistic regression revealed that fluconazole prophylaxis was independently associated with a lower risk of IFI. There was no difference in the frequency of cholestasis between the control and fluconazole groups. CONCLUSIONS Prophylactic administration of fluconazole to all ELBW infants was associated with significantly decreased rates of IFI without associated adverse effects.

Abstract
OBJECTIVE To evaluate the literature regarding the use of fluconazole prophylaxis in high-risk neonates. DATA SOURCES Literature was accessed through MEDLINE (February 2001-August 2009) using the search terms fluconazole and prophylaxis, with limits for age group (ie, birth-18 y). Reference citations from identified articles were also reviewed. DATA SELECTION AND DATA EXTRACTION All prospective and retrospective studies in English identified from MEDLINE were evaluated. DATA SYNTHESIS Critically ill neonates possess a number of risk factors that predispose them to fungal colonization with Candida spp. In many cases, colonization may progress to invasive systemic infections despite efforts aimed at early diagnosis and treatment. Because of its success among immunocompromised patients, fluconazole prophylaxis has been suggested as a possible approach for reducing the rates of both colonization and invasive fungal infections among at-risk neonates. To date, 4 prospective randomized controlled trials and 8 retrospective cohort studies have examined fluconazole prophylaxis in neonates. Although fluconazole prophylaxis appears to reduce the rates of colonization and invasive fungal infections, no trial in this review was able to demonstrate a significant difference in long-term morbidity or mortality. Concerns also remain regarding the adverse effects associated with prolonged exposure to fluconazole therapy. Lack of standardized study designs and treatment regimens also limit widespread recommendation for the use of fluconazole prophylaxis in clinical practice. CONCLUSIONS While it may be beneficial for critically ill neonates with certain predisposing risk factors (eg, central venous access, sustained exposure to broad-spectrum antibiotics, or units with significantly high incidence of invasive fungal infections), existing research does not support the use of fluconazole prophylaxis based on birth weight or gestational age alone. Multifactor analysis evaluating the effect of fluconazole prophylaxis is necessary to establish which neonates would benefit from this practice.

Abstract
OBJECTIVE Preterm neonates with candidemia frequently have persistently positive blood cultures, despite the use of conventional antifungal therapy. Our institutional treatment protocol for invasive candidiasis incorporates lipid complex amphotericin B as initial therapy with the sequential addition of fluconazole and high-dose micafungin (10 mg kg(-1)) every 48 to 72 h, if cultures from a sterile site remain positive. Our study objectives were to compare the clinical profiles and outcomes of preterm neonates with candidemia that responded to or were refractory to conventional antifungals. We further evaluate the clinical efficacy of high-dose micafungin pharmacotherapy of refractory candidemia. STUDY DESIGN A chart review was performed on preterm infants (n=29) with invasive candidiasis and demographic, microbiologic and outcome data abstracted. Proportions and continuous variables were compared between the groups using Fisher's exact two-tailed test and t-test. RESULT The refractory (n=19) candidemia and early responder (n=10) groups had comparable mean (+/-s.d.) gestation, 27(+/-3.1) vs 27.8 (+/-2.7) weeks. The refractory group was administered antibiotics for a longer duration, 14.5 (+/-10.3) vs 7.1 (+/-5) days, had a preponderance of non-albicans infections, 11 (57.9%) vs 1 (10%) and were on enteral feeds > 20 ml kg(-1) day(-1) significantly less often (21 vs 70%). Mortality was significantly higher (53 vs 20%) and fungal clearance rates lower (63.1 vs 90%), with a longer duration to clearance in the group with refractory candidemia. Mean aspartate aminotransferase (AST) showed a statistically significant increase following micafungin treatment, although clinical significance remains unclear. CONCLUSION Candidemia refractory to conventional antifungals is associated with prolonged antibiotic use, lack of enteral nutritive feeds and non-albicans infection. Despite high-dose micafungin pharmacotherapy in combination with conventional antifungals, infants with refractory candidemia had high mortality and poor fungal clearance.

Abstract
Hospital-acquired infections are one of the leading causes of preventable morbidity and mortality in neonatal intensive care units (NICUs). Device-related infections, such as catheter-associated blood stream infections (CABSIs) and ventilator-associated pneumonia (VAP), are the most common nosocomial infections. This review examines the pathogenesis of CABSIs and methods, widely accepted and novel, that can be used to help prevent them. Strategies to prevent fungal infections, which are often associated with the presence of a central venous catheter, are also reviewed. Finally, the dilemmas in the diagnosis and prevention of VAP in the NICU are discussed.
