Abstract
Objective: To evaluate the efficacy, safety, and fungal sensitivity of prophylactic fluconazole use in very premature infants. Methods: We performed a retrospective historical comparative analysis of 196 very premature infants (113 in the prophylaxis group and 83 in the rescue group). The incidence of nosocomial fungal infection (NCFI) and pathogenic fungi, their drug sensitivity, and the minimum inhibitory concentration (MIC) of fluconazole were compared between the two groups. We also analyzed differences in short-term adverse outcomes, such as drug-induced liver or renal function disruption, fungal-attributable death, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), periventricular leukomalacia (PVL), intraventricular hemorrhage (IVH), and necrotizing enterocolitis (NEC), between the groups. The effects of the prophylactic fluconazole strategy on NCFI and short-term adverse outcomes were assessed by multivariate logistic regression. Results: Candida albicans (46.7%) and Candida glabrata (43.3%) were the main culprit pathogens causing NCFI. The incidence of NCFI was significantly lower in the prophylaxis group than in the rescue group (15.9 vs. 45.8%, P < 0.001). However, fewer fungi were completely sensitive to fluconazole (40 vs. 85%, P < 0.05) and the MIC of fluconazole was higher [16.0 (3.5 ~ 16.0) vs. 3.0 (1.0 ~ 8.0) μg/ml, P < 0.001] in the prophylaxis group than in the rescue group. Compared with the rescue group, the prophylaxis group had a lower risk of NCFI (adjusted OR 0.25; 95% CI 0.11, 0.55). Additionally, the prophylaxis group had significantly lower risks of combined outcomes (one or more complications, such as BPD, ROP needing interventions, PVL/IVH (grade > 2), NEC stage ≥2, and fungal-attributable death) (adjusted OR 0.44; 95% CI 0.21, 0.92). There was no significant difference in serum alanine transferase (ALT), aspartate transaminase (AST), creatinine (Cr), or direct bilirubin (DBIL) levels between the two groups. Conclusions: Fluconazole prophylaxis reduced NCFI and improved combined clinical outcomes in very premature infants, with no increased risks of serious short-term adverse side effects; however, the MIC of fluconazole showed significant increases. Therefore, further optimization of preventive strategies is necessary to maintain the sensitivity of fluconazole against fungal isolates.

Abstract
BACKGROUND Increased understanding of characteristics of urinary tract infection (UTI) among very low birthweight infants (VLBW) might lead to improvement in detection and treatment. Continuous monitoring for abnormal heart rate characteristics (HRC) could provide early warning of UTIs. OBJECTIVE Describe the characteristics of UTI, including HRC, in VLBW infants. METHODS We reviewed records of VLBW infants admitted from 2005-2010 at two academic centers participating in a randomized clinical trial of HRC monitoring. Results of all urine cultures, renal ultrasounds (RUS), and voiding cystourethrograms (VCUG) were assessed. Change in the HRC index was analyzed before and after UTI. RESULTS Of 823 VLBW infants (27.7±2.9 weeks GA, 53% male), 378 had > / = 1 urine culture obtained. A UTI (≥10,000 CFU and >five days of antibiotics) was diagnosed in 80 infants, (10% prevalence, mean GA 25.8±2.0 weeks, 76% male). Prophylactic antibiotics were administered to 29 (36%) infants after UTI, of whom four (14%) had another UTI. Recurrent UTI also occurred in 7/51 (14%) of infants not on uroprophylaxis after their first UTI. RUS was performed after UTI in 78%, and hydronephrosis and other major anomalies were found in 19%. A VCUG was performed in 48% of infants and 18% demonstrated vesicoureteral reflux (VUR). The mean HRC rose and fell significantly in the two days before and after diagnosis of UTI. CONCLUSIONS UTI was diagnosed in 10% of VLBW infants, and the HRC index increased prior to diagnosis, suggesting that continuous HRC monitoring in the NICU might allow earlier diagnosis and treatment of UTI.

Abstract
AIM Our aim was to identify the clinical features and outcome of multidrug resistant Candida auris (CA) infection in neonates. METHODS This is a retrospective case cohort study of 17 neonates who developed sepsis caused by CA infection in a tertiary care neonatal intensive care unit over 3 years. The risk factors, clinical features, treatment and outcome were studied. RESULTS The mean gestation was 32.4 ± 4.9 weeks with overall mortality of 41%. Clinical features were indistinguishable from other causes of sepsis. CA was sensitive to micafungin but resistant to fluconazole and had variable sensitivity to voriconazole and amphotericin. Survival improved to 83% when infants were treated with a combination of micafungin and amphotericin. Non-survivors were of lower birthweights and had other risk factors. CONCLUSIONS The management guidelines and infection control measures are described in this largest series of neonatal CA infection. Treatment with a combination of amphotericin and micafungin improved the outcome.

Abstract
Candida parapsilosis causes ~35% of all candidemia cases in neonates. High-resolution fingerprinting of C. parapsilosis isolates from neonatal intensive care unit (NICU) patients in Maternity Hospital (MH) was performed to identify epidemiologically related strains. Sixty-eight bloodstream/colonizing strains isolated from 59 NICU patients, two isolates from health care workers (HCWs) from MH and 18 bloodstream isolates from two other hospitals were used. Six microsatellite markers were employed, isolates were assigned a numerical microsatellite genotype (MSG), dendrogram was constructed and similarities between genotypes were visualized by minimum spanning tree. Fifty bloodstream isolates from MH yielded 37 MSGs with 20 isolates clustering in 7 MSGs. Duplicate isolates and colonizing strains yielded same/highly similar MSG as bloodstream isolates. Colonizing strains from two non-candidemia patients yielded unique MSGs while others belonged to a cluster. All isolates from HCWs and from two other hospitals belonged to unique MSGs. Cluster isolates came from patients in NICU-1 or from neonates in NICU-1 and other NICUs. Clonal complexes comprising closely related genotypes indicative of microevolution were also detected. Our data show that some C. parapsilosis strains have persisted in MH environment over several years and these endemic genotypes were transmitted to other patients in NICU-1 and/or other nearby NICUs.

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
INTRODUCTION Candida is a leading cause of healthcare-associated bloodstream infections in the United States. Infants and children have unique risk factors for candidemia, and the Candida species distribution in this group is different that among adults; however, candidemia epidemiology in this population has not been described recently. METHODS We conducted active population-based candidemia surveillance in 4 US metropolitan areas between 2009 and 2015. We calculated incidences among neonates (0-30 days old), infants (0-364 days old), and noninfant children (1-19 years old), documented their clinical features and antifungal drug resistance. RESULTS We identified 307 pediatric candidemia cases. Incidence trends varied according to site, but overall, the incidence in neonates decreased from 31.5 cases/100000 births in 2009 to 10.7 to 11.8 cases/100000 births between 2012 and 2015, the incidence in infants decreased from 52.1 cases/100000 in 2009 to 15.7 to 17.5 between 2012 and 2015, and the incidence in noninfant children decreased steadily from 1.8 cases/100000 in 2009 to 0.8 in 2014. Common underlying conditions were prematurity in neonates (78%), surgery in nonneonate infants (38%), and malignancy in noninfant children (28%). Most neonate cases were caused by C albicans (67%), whereas non-C. albicans species accounted for 60% of cases in nonneonate infants and noninfant children. Fluconazole and echinocandin resistance rates were low overall. Thirty-day crude mortality was 13%. CONCLUSIONS The incidence of candidemia among neonates and infants declined after 2009 but remained stable from 2012 to 2015. Antifungal drug resistance is uncommon. Reasons for the lack of recent declines in neonatal and infant candidemia deserve further exploration. In this article, we describe the epidemiology of candidemia in children in the United States and on the basis of data collected as part of US Centers for Disease Control and Prevention active population-based surveillance. Trends in incidence, clinical characteristics, species distribution, and resistance rates are presented.

Abstract
OBJECTIVE To investigate whether exposure to inhibitors of gastric acidity, such as H2 blockers or proton pump inhibitors, can independently increase the risk of infections in very low birth weight (VLBW) preterm infants in the neonatal intensive care unit. STUDY DESIGN This is a secondary analysis of prospectively collected data from a multicenter, randomized controlled trial of bovine lactoferrin (BLF) supplementation (with or without the probiotic Lactobacillus rhamnosus GG) vs placebo in prevention of late-onset sepsis (LOS) and necrotizing enterocolitis (NEC) in preterm infants. Inhibitors of gastric acidity were used at the recommended dosages/schedules based on the clinical judgment of attending physicians. The distribution of days of inhibitors of gastric acidity exposure between infants with and without LOS/NEC was assessed. The mutually adjusted effects of birth weight, gestational age, duration of inhibitors of gastric acidity treatment, and exposure to BLF were controlled through multivariable logistic regression. Interaction between inhibitors of gastric acidity and BLF was tested; the effects of any day of inhibitors of gastric acidity exposure were then computed for BLF-treated vs -untreated infants. RESULTS Two hundred thirty-five of 743 infants underwent treatment with inhibitors of gastric acidity, and 86 LOS episodes occurred. After multivariate analysis, exposure to inhibitors of gastric acidity remained significantly and independently associated with LOS (OR, 1.03; 95% CI, 1.008-1.067; P = .01); each day of inhibitors of gastric acidity exposure conferred an additional 3.7% odds of developing LOS. Risk was significant for Gram-negative (P < .001) and fungal (P = .001) pathogens, but not for Gram-positive pathogens (P = .97). On the test for interaction, 1 additional day of exposure to inhibitors of gastric acidity conferred an additional 7.7% risk for LOS (P = .003) in BLF-untreated infants, compared with 1.2% (P = .58) in BLF-treated infants. CONCLUSION Exposure to inhibitors of gastric acidity is significantly associated with the occurrence of LOS in preterm VLBW infants. Concomitant administration of BLF counteracts this selective disadvantage. TRIAL REGISTRATION isrctn.org: ISRCTN53107700.

Abstract
Background There have been many studies supporting fluconazole prophylaxis in preterm infants for prevention of invasive fungal infections (IFIs). However, the routine use of fluconazole prophylaxis in neonatal intensive care units (NICUs) raises concerns with respect to resistance development, including the selection of resistant Candida species. We aimed to evaluate the efficacy and safety of fluconazole prophylaxis in extremely low birth weight (ELBW) infants. Methods An interventional pre-post cohort study at two tertiary NICUs was conducted. Data from two 5-year periods with and without fluconazole prophylaxis (Mar 2008–Feb 2013 and Mar 2003–Feb 2008) was compared. Prophylactic fluconazole was administered starting on the 3rd day at a dose of 3 mg/kg twice a week for 4 weeks during the prophylaxis period. Results The fluconazole prophylaxis group consisted of 264 infants, and the non-prophylaxis group consisted of 159 infants. IFI occurred in a total of 19 neonates (4.7 %) during the 10-year study period. Fluconazole prophylaxis lower the fungal colonization rate significantly (59.1 % vs. 33.9 %, P <0.001). However, the incidence of IFIs in ELBW infants was not reduced after fluconazole prophylaxis (4.4 % vs. 5.5 %, P = 0.80). Rather, although the increase did not reach statistical significance, fluconazole prophylaxis tended to increase the incidence of invasive infections involving fluconazole-resistant C. parapsilosis (0 % vs. 41.7 %, P = 0.11). Conclusions Fluconazole prophylaxis was not efficacious in decreasing IFIs in ELBW infants. There is a need for targeting prophylaxis to greatest risk population and prospective studies to measure the long-term effect of fluconazole prophylaxis on the emergence of organisms with antifungal resistance.

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
Invasive fungal infections in preterm neonates in the neonatal intensive care unit are predominantly caused by Candida spp, and have a high burden of morbidity and mortality. Effective prophylactic strategies have recently become available, but the identification of the best possible strategies to manage high-risk infants is still a priority. Choice and use of appropriate antifungal drugs needs careful assessment of neonatal characteristics, the epidemiology and drug pharmacokinetics. Ideally, antifungal drugs for preterm neonates should target fungal bio-films, prevent or effectively treat end-organ localisations, be active against fluconazole-resistant Candida species, and have reliable safety and tolerability profiles. The paper reviews the state-of-the-art in the area of neonatal fungal infections, and addresses some open questions related to the best possible prophylactic and therapeutic strategies to be implemented in such unique patients.

Abstract
Infants in neonatal intensive care units (NICUs) are highly susceptible to infection due to the immaturity of their immune systems. Healthcare-associated infections (HCAIs) are associated with prolonged hospital stay, and represent a significant risk factor for neurological development problems and death. Improving HCAI control is a priority for NICUs. Many factors contribute to the occurrence of HCAIs in neonates such as poor hand hygiene, low nurse–infant ratios, environmental contamination and unnecessary use of antibiotics. Prevention is based on improving neonatal management, avoiding unnecessary use of central venous catheters, restricting use of antibiotics and H2 blockers, and introducing antifungal prophylaxis if necessary. Quality improvement interventions to reduce HCAIs in neonates seem to be the cornerstone of infection control.

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
OBJECTIVE The aim of the article is to provide an update on medication use in infants admitted to the neonatal intensive care unit (NICU) in the United States and examine how use has changed over time. STUDY DESIGN We performed a retrospective review (2005-2010) of a large prospectively collected administrative database. RESULT Medications most commonly administered during the study period were ampicillin, gentamicin, caffeine citrate, vancomycin, beractant, furosemide, fentanyl, dopamine, midazolam, and calfactant (56-681 exposures per 1,000 infants). Those with the greatest relative increase in use included azithromycin, sildenafil, and milrinone. Medications with the greatest relative decrease in use included theophylline, metoclopramide, and doxapram. CONCLUSION Medication use in the NICU has changed substantially over time, and only 35% of the most commonly prescribed medications are Food and Drug Administration -approved in infants.

Abstract
BACKGROUND Fluconazole prophylaxis has demonstrated efficacy in single and multicenter randomized controlled trials without side effects or emergence of resistance. Additional evidence based on incidence of invasive Candida infections, multicenter data, resistance, and safety is desired. METHODS We conducted a case-control analysis of efficacy and safety of fluconazole prophylaxis from a multicenter database from a neonatal infection study that included 2017 infants <1250 grams from 95 NICUs. Infants receiving intravenous antifungal prophylaxis were pre-identified during enrollment in the parent study. For each infant receiving antifungal prophylaxis (case), three infants not receiving antifungal (controls) were matched by birth weight (± 50 g), by gestational age (± 1 week), gender, and study site. RESULTS Fluconazole prophylaxis was administered to 127 patients [754 ± 163 g birth weight (BW) and 25.4 ± 1.7 weeks gestational age (GA)] and were compared with 399 control patients (756 ± 163 g BW and 25.5 ± 1.8 weeks GA). Invasive Candida infection occurred in 0.8% (1 of 127) infants who received fluconazole prophylaxis compared with 7.3% (29 of 399) of matched controls (p = 0.006). Candida bloodstream infection occurred in 0.8% (1 of 127) fluconazole prophylaxis infants compared with 5.5% (22 of 399) of matched controls (p = 0.02). There were no differences in late-onset sepsis due to gram-positive or gram-negative organisms, focal bowel perforation, necrotizing enterocolitis, cholestasis, or overall mortality. CONCLUSION Fluconazole prophylaxis is safe and efficacious in preventing invasive Candida infections. Even in NICUs with a low incidence of invasive Candida infections, antifungal prophylaxis for high-risk infants is a proven and safe opportunity for infection prevention in these patients.

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
BACKGROUND Candida species and coagulase-negative staphylococci (CoNS) are common etiologies of hospital acquired bloodstream infection in the neonatal intensive care unit (NICU). Sepsis with either organism may result in serious infectious sequelae and along with other staphylococci are the most common causes of abscess formation in preterm infants. This increased incidence of abscess formation may be in part due to adherence factors of both pathogens. METHODS All cases of concurrent positive blood cultures for both Candida species and CoNS were identified from the microbiology database in NICU patients from January 1998 to December 2000 and analyzed for risk factors and outcomes. In vitro co-aggregation studies between Candida albicans and Staphylococcus epidermidis were also performed. RESULTS Six premature infants were identified as having concurrent Candida and CoNS bloodstream infections during this time period. Four of the six patients developed end-organ dissemination with abscess or infected thrombus formation. Three of the six patients expired during or after their infection. In vitro, co-aggregation studies did not demonstrate reproducible direct adherence between C. albicans and S. epidermidis. CONCLUSIONS Simultaneous bloodstream infection with Candida and CoNS, compared to either one alone, is more likely to predispose to abscess formation, septic thrombophlebitis and mortality. Further studies are needed to examine the pathogenesis of these complex infections.

Abstract
The management of neonatal sepsis is challenging owing to complex developmental and environmental factors that contribute to inter-individual variability in the pharmacokinetics and pharmacodynamics of many antimicrobial agents. In this review, we describe (i) the changing epidemiology of early- and late-onset neonatal sepsis; (ii) the pharmacologic considerations that influence the safety and efficacy of antibacterials, antifungals, and immunomodulatory adjuvants; and (iii) the recommended dosing regimens for pharmacologic agents commonly used in the treatment and prevention of neonatal sepsis. Neonatal sepsis is marked by high morbidity and mortality, such that prompt initiation of antimicrobial therapy is essential following culture collection. Before culture results are available, combination therapy with ampicillin and an aminoglycoside is recommended. When meningitis is suspected, ampicillin and cefotaxime may be considered. Following identification of the causative organism and in vitro susceptibility testing, antimicrobial therapy may be narrowed to provide targeted coverage. Therapeutic drug monitoring should be considered for neonates receiving vancomycin or aminoglycoside therapies. For neonates with invasive fungal infections, the development of new antifungal agents has significantly improved therapeutic outcomes in recent years. Liposomal amphotericin B has been found to be safe and efficacious in patients with renal impairment or toxicity caused by conventional amphotericin B. Antifungal prophylaxis with fluconazole has also been reported to dramatically reduce rates of neonatal invasive fungal infections and to improve long-term neurodevelopmental outcomes among treated children. Additionally, several large multicenter studies are currently investigating the safety and efficacy of oral lactoferrin as an immunoprophylactic agent for the prevention of neonatal sepsis.

Abstract
BACKGROUND Active surveillance is necessary for improving the management and outcomes of patients with candidemia. The aim of this study was to describe the epidemiologic and clinical features of candidemia in pediatric patients in Latin America. METHOD Prospective, multicenter, surveillance study of candidemia in a pediatric population from 23 hospitals in 8 Latin America countries between November 2008 and October 2010. RESULTS Three hundred and two cases of candidemia were reported with a median incidence of 0.81/1000 admissions. Eighty nine (29%) were neonates. The main risk factors were prematurity, intensive care unit (ICU) admission, parenteral nutrition, respiratory disease and mechanical ventilation in neonates and malignancy, neutropenia, neurological disease and previous use of corticosteroids in children. The main species isolated in neonates and children were Candida albicans (43.8% and 35.7%), Candida parapsilosis (27.0% and 26.3%) and Candida tropicalis (14.6% and 14.6%), respectively. The most frequent antifungal therapy used in neonates and children was deoxycholate-amphotericin-B (43.8% and 29.1%) and fluconazole (28.1% and 53.1%). Seventeen neonates (19.1%) and 20 children (9.4%) did not receive antifungal therapy. The 30-day survival rate was 60% in neonates and 72% in children (P = 0.02). Survival was significantly higher in treated than in nontreated neonates (72% vs. 24%; P < 0.001). A multivariate analysis showed that independent predictors for 30-day mortality in children were renal disease (odds ratio: 4.38, 95% confidence interval: 1.92-10.1, P < 0.001) and receipt of corticosteroids (odds ratio: 2.08, 95% confidence interval: 1.04-4.17, P = 0.04). CONCLUSIONS To our knowledge, this is the first prospective, multicenter surveillance study of candidemia in children in Latin America. This epidemiologic information may provide us with methods to improve preventive, diagnostic and therapeutic strategies in our continent.

Abstract
AIM This study aims to compare the efficacy of orally administered Saccharomyces boulardii versus nystatin in prevention of fungal colonization and invasive fungal infections in very low birth weight infants. METHOD A prospective, randomized comparative study was conducted in preterm infants with a gestational age of ≤ 32 weeks and birth weight of ≤ 1,500 g. They were randomized into two groups, to receive S. boulardii or nystatin. Skin and stool cultures were performed for colonization and blood cultures for invasive infections, weekly. RESULTS A total of 181 infants were enrolled (S. boulardii group, n = 91; nystatin group, n = 90). Fungal colonization of the skin (15.4 vs 18.9 %, p = 0.532) and the stool (32.2 vs 27 %, p = 0.441) were not different between the probiotic and nystatin groups. Two patients had Candida-positive blood culture in the nystatin group whereas none in the probiotic group. Feeding intolerance, clinical sepsis, and number of sepsis attacks were significantly lower in the probiotics group than in the nystatin group. CONCLUSION Prophylactic S. boulardii supplementation is as effective as nystatin in reducing fungal colonization and invasive fungal infection, more effective in reducing the incidence of clinical sepsis and number of sepsis attacks and has favorable effect on feeding intolerance.

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. Other publications in this series include: 'Recommendations for the diagnosis of candidemia in Latin America', 'Recommendations for the management of candidemia in adults in Latin America', and 'Recommendations for the management of candidemia in children in Latin America'.

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. Other publications in this series include: 'Recommendations for the diagnosis of candidemia in Latin America', 'Recommendations for the management of candidemia in adults in Latin America', and 'Recommendations for the management of candidemia in children in Latin America'.

Abstract
We report the case of a 31-week gestational age neonate with Candida albicans sepsis and a hepatic abscess. Diagnosis relied on clinical and radiological signs of sepsis, liver function impairment and culture isolation of Candida spp. from sterile sites. Liver ultrasound documented the presence of a multiloculated abscess. Treatment with micafungin (3 mg/kg/day) resulted in normalization of liver function and inflammatory laboratory values and improvement of clinical condition. After 30 days of treatment, the liver abscess resolved and at the 8-month follow up the infant is doing well. Prompt diagnosis and antifungal treatment avoided surgical drainage and liver surgery in this high-risk neonate.

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
BACKGROUND Treatment and prophylaxis of sepsis in very low birth weight neonates is a matter of concern and research is being undertaken with the aim to give rise to shared approaches based on solid evidence. As part of a European initiative, a survey was set up to describe the use of two drugs in this area. The Italian national practices concerning neonatal sepsis, as well as calls for related guidance, are described. METHODS A standardized and previously tested questionnaire was submitted online to all Italian level III NICUs. A 5-point Likert scale was used to analyze attitudinal replies. Categorical variables were compared by χ2 analysis and 2-tailed P-values are reported. RESULTS Data was provided by 38 Italian NICUs (36% of the country's level III centers), 53% of which have 1-10 cases of bacterial sepsis monthly and 90% a prevalence of <1% fungal infections. Ciprofloxacin and fluconazole treatment for neonatal sepsis are scantly used in Italian NICUs (13% and 45%, respectively). Major concerns are related to the safety of ciprofloxacin and the efficacy of fluconazole. On the contrary, prophylaxis of fungal infections is a routine approach in many Italian NICUs. The use of both ciprofloxacin and fluconazole is characterized by a large inter-NICU variability in dose and scheme of use. The lack of adequate, shared evidence is a common consideration made by the survey participants. CONCLUSIONS Common approaches are needed to standardize and update a national drug strategy for the prevention and treatment of sepsis in very low birth weight newborns. This can be achieved through collaborative initiatives aimed at setting up guidelines, based on available data, and multicenter trials to produce new evidence that will address the knowledge gaps.

Abstract
Candida parapsilosis (CP) (n = 40) isolated from an unselected patient population in the neonatal intensive care units (NICUs) of three US hospitals were collected over periods of 3.5-9 years. Two previously published microsatellite markers and three additional trinucleotide markers were used to produce multiplex genotypes, which revealed broad strain diversity among the NICU isolates with a combined index of discrimination (D) = 0.997. A cluster of eight related CP strains from four infants in a single NICU was observed. An extended collection of 24 CP isolates from the general population of that hospital showed that the cluster of NICU isolates was related to three isolates from general hospital patients. This microsatellite marker set is suitable to investigate clusters of colonizing and infecting strains of CP.

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
BACKGROUND The aim of the present study was to evaluate the risk factors, demographic features, treatment and clinical outcome associated with candidemia in a neonatal intensive care unit (NICU) within an 8 year period. METHODS The data of infants who were diagnosed as having candidemia, were evaluated. RESULTS Between January 2000 and December 2007, a total of 28 candidemia episodes were identified in 28 infants. A 1.1% candidemia incidence was documented in the neonatal intensive care unit (NICU). The species most frequently causing candidemia were Candida parapsilosis (57.1%), followed by C. albicans (42.9%). The main predisposing factors for candidemia with C. parapsilosis included presence of maternal pre-eclampsia, prematurity, prolonged mechanical ventilation, prolonged total parenteral nutrition and presence of jaundice. Retinopathy of prematurity and bronchopulmonary dysplasia were the most frequently seen underlying illnesses in infants with C. parapsilosis. In the present study, 13 infants (46.4%) had evidence of organ dissemination. The mortality rate was 42.8% in infants with candidemia. Mean leukocyte counts and mean C-reactive protein were significantly higher in neonates who died compared with those who survived. CONCLUSION Candida parapsilosis (57.1%) was the leading causative organism, followed by C. albicans (42.9%) in infants. The rate of organ dissemination in the present cases was high. The mortality rate was 42.8% in infants with candidemia.

Abstract
Fluconazole is a triazole antifungal agent that is widely used in the nursery. It is available in both intravenous and oral formulation, and is active against most of the fungal pathogens that require treatment when retrieved from culture samples in neonatal intensive care units. Although clinical use has been wide for over 15 years, there have been small safety and efficacy studies completed in young infants. Randomised clinical trials assessing effectiveness of this agent in prevention of systemic fungal infections in neonates have been published in the last decade, and one large additional randomised study has been recently completed. Nevertheless, a certain degree of uncertainty still exists regarding the kinetics and appropriate dosing of this agent in premature and term infants, as well as regarding safety. Areas of poignant debate include the feasibility of loading dose strategies, appropriate dosages in the early days of life in the different subgroups of preterm infants, and long-term safety of fluconazole administered in prophylaxis during the first weeks of life in extremely premature infants. This paper reviews the most recent evidence on fluconazole and its role in the NICU settings.

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
The aim of our study was to assess epidemiological features of neonatal invasive candidiasis in Farhat Hached hospital of Sousse, Tunisia, including incidence, risk factors, mortality, species distribution and antifungal susceptibility. Laboratory data from 1995 to 2010 and medical records of 127 invasive candidiasis cases were reviewed. We tested the susceptibility of 100 Candida sp isolates by using ATB fungus(®) 3 and to fluconazole by using E-test(®) strips. A total of 252 cases of neonatal invasive candidiasis occurred over the study period. The incidence increased 1.8-fold from 1995 to 2006 and decreased fourfold from 2007 to 2010. Candida albicans was the predominant species up to 2006 and a shift in the species spectrum was observed with increase of the non-albicans species mainly C. parapsilosis. The agreement between the ATB Fungus(®) and the E-test(®) for determining fluconazole susceptibility was high. All tested isolates were susceptible to fluconazole, flucytosine, amphotéricine B and voriconazole and the itraconazole resistance rate was 5%. The mortality rate was 63%. The invasive candidiasis incidence increased from 1995 to 2006 and decreased from 2007 to 2010. The spectrum of Candida species and the lack of fluconazole-resistant strains argue for the usefulness of fluconazole as an empiric treatment.

Abstract
BACKGROUND Lactoferrin is a mammalian milk glycoprotein involved in innate immunity. Recent data show that bovine lactoferrin (bLF) prevents late-onset sepsis in preterm very low birth weight (VLBW) neonates. METHODS This is a secondary analysis of data from a multicenter randomized controlled trial where preterm VLBW neonates randomly received bLF (100 mg/day; group A1), bLF + Lactobacillus rhamnosus GG (10(6) colony-forming units per day; group A2), or placebo (group B) for 6 weeks. Here we analyze the incidence rates of fungal colonization, invasive fungal infection (IFI), and rate of progression from colonization to infection in all groups. RESULTS This study included 472 neonates whose clinical, nutritional, and demographical characteristics were similar. Overall, the incidence of fungal colonization was comparable (17.6%, 16.6%, and 18.5% in A1, A2, and B, respectively; P = .89 [A1] and .77 [A2]). In contrast, IFIs were significantly decreased in A1 and A2 (0.7% and 2.0%, respectively) compared with B (7.7%; P = .002 [A1] and .02 [A2]), and this was significantly true both in <1000 g (0.9% [A1] and 5.6% [A2], vs 15.0%) and in 1001 to 1500 g infants (0% and 0% vs 3.7%). The progression rate colonization-infection was significantly lower in the bLF groups: 3.7% (A1) and 12% (A2), vs 41.9%; P < .001 (A1) and P = .02 (A2). No IFI-attributable deaths occurred in the treatment groups, versus 2 in placebo. No adverse effects or intolerances occurred. CONCLUSIONS Prophylactic oral administration of bLF reduces the incidence of IFI in preterm VLBW neonates. No effect is seen on colonization. The protective effect on IFI is likely due to limitation of ability of fungal colonies to progress toward invasion and systemic disease in colonized infants.

Abstract
Evaluation of epidemiological trends, risk factors, and clinical outcome associated with candidemia at a neonatal intensive care unit is reported. From January 2005 to December 2009, forty candidemia cases were identified. C. albicans and C. parapsilosis were the most common species recovered (69 and 24%, respectively). All C. parapsilosis strains were susceptible to antifungals, whereas, C. albicans exhibited higher resistance rates to azoles. Low birth weight, low gestational age, presence of central lines, endotracheal intubation, total parenteral nutrition, previous use of antibiotics, steroids, previous episode(s) of bacteremia and prolonged stay in intensive care unit were common features associated with candidemia. C. albicans was most often isolated from extremely low birth weight neonates as compared to non-albicans Candida (P < 0.01). Mortality rate was 35.7% and was associated with low gestational age (P < 0.01), low birth weight (P < 0.01), and presence of renal failure (P < 0.05). Furthermore, a critical review of recent published case series is presented.

Abstract
In the USA, the incidence of invasive candidiasis in neonates is respectively 0.3% of infants over 2500 g and up to 20% of infants less than 1000 g. Their incidence is increasing. Two populations of newborn infants are particularly vulnerable: the premature infants and newborn infants with severe neonatal digestive diseases. Fifty percent of infants hospitalized in NICU are colonized with Candida at the end of the first week of hospitalization; a direct relationship exists between the importance of colonization and the invasive infection risk. C. albicans is the species most often responsible for invasive candidiasis in the newborn. These infections represent the third cause of related-catheter infection in the USA. Mortality rate in neonates linked to this disease is 20 to 50%; morbidity primarily concerns brain and lungs. Neonatal invasive candidiasis risk factors are known and a primary prevention is possible. The diagnosis of neonatal invasive candidiasis is difficult and often delayed because of a polymorphic clinical expression. Empiric and preemptive treatment are based on the use of amphotericin B. Prophylactic treatment using fluconazole of newborns with birth weight ≤ 1000 grams and/or gestational age ≤ 27 weeks gestation is recommended by the American Academy of Paediatrics and the Infectious Diseases Society of America. A better knowledge of French epidemiological data in this area would improve both the diagnosis and therapeutic management of this disease.

Fluconazole prophylaxis in extremely low birth weight infants and neurodevelopmental outcomes and quality of life at 8 to 10 years of age. J Pediatr 2011; 158:759-765.e1. [PMID: 21168853 DOI: 10.1016/j.jpeds.2010.11.002] [Citation(s) in RCA: 45] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2010] [Revised: 09/10/2010] [Accepted: 11/01/2010] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To examine the long-term effects of fluconazole prophylaxis in extremely low birth weight infants. STUDY DESIGN Neurodevelopmental status and quality of life of survivors from a randomized, placebo-controlled trial of fluconazole prophylaxis were evaluated at 8 to 10 years of life using the Vineland Adaptive Behavior Scales-II (VABS-II) and the Child Health Questionnaire Parent-Completed Form 28 (CHQ-PF28), respectively. RESULTS VABS-II Domain Scores for the fluconazole-treated (n = 21; 9.1 ± 0.7 years) compared with the placebo group (n = 17; 9.3 ± 0.8 years) were similar for communication [94.6 (±14.8) versus 92.6 (±12.6), P = .65], daily living skills [87.9 (±10.6) versus 87.4 (±9.3), P = .89], socialization [97.2 (±9.2) versus 94.4 (±7.9), P = .31], and motor skills [92.1 (±17.8) versus 95.1 (±14.6), P = .57]. Internalizing and externalizing behaviors and maladaptive behavior index were also similar. The CHQ-PF28 revealed no differences between the two groups regarding quality of life. Survivors were also happy or satisfied with school (90% versus 100%, P = .49), friendships (90% versus 88%, P = 1.00), and life (95% versus 100%, P = 1.00). Self esteem scores were 87.3 ± 15.7 versus 89.7 ± 10.4 (P = .59). There were also no differences between groups regarding emotional difficulties or behavior problems. CONCLUSIONS Fluconazole prophylaxis for the prevention of invasive Candida infections is safe in extremely low birth weight infants and does not appear to be associated with any long-term adverse effects on neurodevelopment and quality of life at 8 to 10 years of life.

Abstract
Fungal-related morbidity and mortality is a major concern for most neonatal intensive care units (NICUs) worldwide. Incidence rates are increasing and might be higher than reported due to the challenges associated with diagnosing fungal infections. As preterm neonates display clinical characteristics that make them prone to Candida spp infections, and there is a high frequency of severe neurodevelopmental sequelae in those who survive neonatal fungal infections, specific prevention--rather than empiric or pre-emptive treatment--should be the optimal strategy. Besides stewardship of drug use and efforts to minimize invasive cares, pharmacological prevention with use of fluconazole has proved highly effective in decreasing the rates of fungal sepsis in very low birth weight (VLBW) neonates. Alternative options needing further and more conclusive assessments include use of nystatin, bovine lactoferrin or probiotics.

Abstract
Sepsis-related morbidity and mortality are major problems in NICU. Preterm neonates display clinical characteristics that make them prone to infections. Due to the high frequency of severe neurodevelopmental sequelae in survivors, the best possible strategy to manage sepsis in NICU is to prevent them. Hygiene, cohorting, stewardship on use of H2-blockers, steroids and broad-spectrum antibiotic are mandatory, as well as proper management of central venous accesses and surgical devices. In addition, clinical research offers the opportunity of adopting pharmacological preventative strategies such as use of palivizumab to prevent RSV infection, use of fluconazole to prevent fungal sepsis, use of probiotics and lactoferrin to enhance the innate immunity, and use of pagibaximab to prevent staphylococcal sepsis.
