RESUMEN
More than one million neonatal deaths occur every year worldwide, of which 99% take place in low-income countries. In Rwanda, nearly 71% of neonatal deaths are preventable and among these, 10% are due to neonatal sepsis. Nevertheless, limited information exists on neonatal sepsis and its associated factors in Rwanda. The objectives of the study were to find prevalence and factors associated with neonatal sepsis among neonates admitted in Kibungo Referral Hospital, Ngoma District, Rwanda. We used a retrospective cross-sectional study design reviewing a subset of neonatal, maternal and laboratory records from Kibungo Hospital in 2017. Data were reviewed and collected from March to May, 2018. Logistic regression and odds ratios were calculated to identify the factors associated with neonatal sepsis at 95% CI, p < 0.05. Of the 972 total neonates' medical records from 2017, we randomly selected 422 of which 12.8% (n = 54) had neonatal sepsis. When blood cultures were positive, 62% grew Klebsiella pneumoniae. Among neonates with sepsis, 38 (70%) recovered while 16 (30%) died. Neonatal sepsis was strongly associated with neonatal age less than or equal to three days (aOR: 2.769, 95% CI 1.312-5.843; p = 0.008); and gestational age less than 37 weeks (aOR: 4.149; CI 1.1878-9.167; p ≤ 0.001). Increased use of blood cultures including sensitivity testing, routine surface cultures of the neonatology and maternity wards facilities, and systematic ward cleaning are all important approaches to prevent and treat neonatal infections in additional to regular neonatal sepsis evaluations.

We conducted a propensity score-matched multivariable regression analysis of 1050 culture-negative neonatal sepsis cases in Malawi, where 160 (15.2%) died. Mortality among neonates with culture-negative sepsis was associated with very low birth weight (adjusted OR (AOR) 12.82, 95% CI 1.23 to 137.49), respiratory distress syndrome (AOR 13.20, 95% CI 2.58 to 83.66), a low Apgar score at 1 min (AOR 3.50, 95% CI 1.21 to 10.72) and at 5 min (AOR 4.77, 95% CI 1.94 to 12.50). Addressing maternal and perinatal factors around health and delivery of care is key to improving outcomes in the context of culture-negative sepsis in neonates from low-income country settings like Malawi.

Introduction: Sepsis remains a major source of morbidity and mortality in neonates, and characterization of immune regulation in the neonatal septic response remains limited. HVEM is a checkpoint regulator which can both stimulate or inhibit immune responses and demonstrates altered expression after sepsis. We hypothesized that signaling via HVEM would be essential for the neonatal response to sepsis, and that therefore blockade of this pathway would improve survival to septic challenge. Methods: To explore this, neonatal mice were treated with cecal slurry (CS), CS with Anti-HVEM antibody (CS-Ab) or CS with isotype (CS-IT) and followed for 7-day survival. Mice from all treatment groups had thymus, lung, kidney and peritoneal fluid harvested, weighed, and stained for histologic evaluation, and changes in cardiac function were assessed with echocardiography. Results: Mortality was significantly higher for CS-Ab mice (72.2%) than for CS-IT mice (22.2%). CS resulted in dysregulated alveolar remodeling, but CS-Ab lungs demonstrated significantly less dysfunctional alveolar remodeling than CS alone (MCL 121.0 CS vs. 87.6 CS-Ab), as well as increased renal tubular vacuolization. No morphologic differences in alveolar septation or thymic karyorrhexis were found between CS-Ab and CS-IT. CS-Ab pups exhibited a marked decrease in heart rate (390.3 Sh vs. 342.1 CS-Ab), stroke volume (13.08 CS-IT vs. 8.83 CS-Ab) and ultimately cardiac output (4.90 Sh vs. 3.02 CS-Ab) as well as a significant increase in ejection fraction (73.74 Sh vs. 83.75 CS-Ab) and cardiac strain (40.74 Sh vs. 51.16 CS-Ab) as compared to CS-IT or Sham animals. Discussion: While receptor ligation of aspects of HVEM signaling, via antibody blockade, appears to mitigate aspects of lung injury and thymic involution, stimulatory signaling via HVEM still seems to be necessary for vascular and hemodynamic resilience and overall neonatal mouse survival in response to this experimental polymicrobial septic insult. This dissonance in the activity of anti-HVEM neutralizing antibody in neonatal animals speaks to the differences in how septic cardiac dysfunction should be considered and approached in the neonatal population.

Background: Although neonatal sepsis is a major public health problem contributing to 30-50% of neonatal deaths in low- and middle-income countries, data on predictors of time to death are limited in Eastern Ethiopia. This study is aimed at determining predictors of time to death among neonates with sepsis admitted in public hospitals in Eastern Ethiopia. Methods: An institutional-based retrospective cohort study was conducted among 415 neonates admitted to referral hospitals in Eastern Ethiopia with sepsis from January 1, 2021, to December 31, 2021. Data were collected from medical records by using structured checklist and entered using EpiData 3.1 and analyzed using Stata 17. The Kaplan-Meier curves and log-rank tests were used to describe survival experience among different categories. The proportional hazard assumption and goodness of fit for the Cox regression model were checked. The Cox regression model was used to identify the significant predictors. Hazard ratios (HRs) with 95% confidence intervals (CI) were calculated. Finally, statistical significance was set at a p value < 0.05 in the Cox regression analysis. Results: Of the 415 neonates with neonatal sepsis, 71 (17.1%) (95% CI: 13.60-21.08) died at discharge, with a median time to death of 14 days. The overall incidence rate of mortality was 36.5 per 1000 neonate days. Low birthweight (AHR = 2.50; 95% CI: 1.15-5.44), maternal age ≥ 35 years (AHR = 3.17; 95% CI: 1.11, 9.04), low fifth-minute Apgar score (AHR: 2.32; 95% CI: 1.30-4.14), and late initiation of breastfeeding (AHR = 4.82; 95% CI: 1.40-16.65) were independent predictors of mortality among neonates with sepsis. Conclusions: Almost one in five neonates with sepsis died at discharge. Low birthweight, maternal age ≥ 35 years, low fifth-minute Apgar score, and late initiation of breastfeeding were predictors of mortality.

BACKGROUND: Streptococcus gallolyticus subspecies pasteurianus (SGP), a subtype of Streptococcus bovis , is an uncommon but important cause of neonatal sepsis. Although uncommon, SGP infections during infancy have been associated with an increased risk of morbidity and mortality. METHODS: This is a systematic review and meta-analysis of available literature on the clinical course and outcomes of infants with SGP infection. Studies were identified using the following MeSH keywords: " Streptococcus gallolyticus ," " Streptococcus bovis ," "newborn" and "infant." Data including perinatal factors, clinical presentation, investigations, treatment and outcomes were extracted and analyzed. RESULTS: A total of 46 articles were identified (116 cases: 60 S. bovis , 56 SGP). The cases were predominantly term (52%), male (57%) and born via vaginal delivery (67%). The most common symptom was fever [67% (95% confidence interval (CI): 43%-84%)], lethargy [66% (95% CI: 32%-89%)], tachypnea [59% (95% CI: 27%-85%)] and irritability [59% (95% CI: 34%-79%)]. Infants with early-onset infections (<3 days of life) were more likely to have respiratory symptoms and bacteremia (73%), whereas late-onset infections presented predominantly with gastrointestinal symptoms. Four mortalities were reported which occurred before antibiotic administration. Isolated bacteria were mostly penicillin-susceptible [95% (95% CI: 78-99%)] and cases treated with penicillin derivative had good recovery. CONCLUSIONS: SGP is an important cause of neonatal sepsis and meningitis. Penicillin derivative is an effective treatment for SGP, and outcomes appear to be favorable.

BACKGROUND: Respiratory distress syndrome is strongly associated with prematurity, including late preterm births. Respiratory distress syndrome has been shown to be associated with certain neonatal morbidities and mortality, but these associations are not well described among late preterm births. OBJECTIVE: We sought to determine the association between respiratory distress syndrome and adverse neonatal outcomes among late preterm (34-36 weeks) born singleton neonates. STUDY DESIGN: This is a retrospective cohort study using California's linked vital statistics and patient discharge data (2008-2019). We included singleton, nonanomalous births with a gestational age of 34-36 weeks. Outcomes of interest were interventricular hemorrhage, necrotizing enterocolitis, retinopathy of prematurity, neonatal sepsis, length of hospital stay, neonatal death, and infant death. Chi-square and multivariable Poisson regression analyses were used to examine the association of respiratory distress syndrome with outcomes at each gestational age. Adjusted risk ratio and 95% confidence interval values were estimated. RESULTS: A total of 242,827 births were included, of which 11,312 (4.7%) had respiratory distress syndrome. We found that among neonates with respiratory distress syndrome, necrotizing enterocolitis was higher at 35 weeks (adjusted risk ratio, 3.97 [95% confidence interval, 1.88-8.41]) and 36 weeks (adjusted risk ratio, 4.53 [95% confidence interval, 1.45-14.13]). Intraventricular hemorrhage, retinopathy of prematurity, neonatal sepsis, and length of hospital stay were significantly higher at 34-36 weeks of gestation in neonates with respiratory distress syndrome. Neonatal death was significantly higher among neonates with respiratory distress syndrome at 35 weeks (adjusted risk ratio, 3.04 [95% confidence interval, 1.58-5.85]) and 36 weeks (adjusted risk ratio, 3.25; 95% confidence interval, 1.59-6.68). In addition, infant death was significantly higher at 35 weeks (adjusted risk ratio, 2.27 [95% confidence interval, 1.43-3.61]) and 36 weeks (adjusted risk ratio, 2.60 [95% confidence interval, 1.58-4.28]). CONCLUSION: We found that respiratory distress syndrome was associated with intraventricular hemorrhage, retinopathy of prematurity, and sepsis at 34-36 weeks of gestation, whereas respiratory distress syndrome was associated with neonatal death, infant death, and necrotizing enterocolitis at 35 and 36 weeks. Clinicians should keep these outcomes in mind when making decisions about delivery timing, the potential benefits of antenatal steroids in pregnancies in the late preterm period, and the management of respiratory distress syndrome in late preterm neonates.

PURPOSE: To assess Gram-positive bacterial (GPB) bloodstream infection (BSI) in neonates, covering incidence, morbidity, mortality, antimicrobial resistance patterns and biomarkers in Region Stockholm, Sweden between 2006 and 2016. METHODS: A population-based retrospective epidemiological study including infants with GPB-BSI, admitted to the neonatal units at Karolinska University Hospital (KUH). Data were collected from patient records, the Swedish Neonatal Quality Register, the microbiological laboratory at KUH and the Swedish Public Health Agency. RESULTS: We identified 357 infants with GPB-BSI, representing an incidence of 1.47/1000 live births (LB). Group B streptococcus (GBS) was the most common pathogen causing BSI in full-term infants and early-onset sepsis (EOS) (0.20/1000 LB), while coagulase-negative staphylococci (CoNS) were predominant in infants born very preterm and in late-onset sepsis (LOS) (0.79/1000 LB). There were no fatal GBS BSI cases, but 10.2% developed meningitis. The GPB case fatality rate was 9.5% and the sepsis fatality rate 2.8%. In GPB-BSI, 1/10 did not have an elevated C-reactive protein level. Staphylococcus aureus (S. aureus) BSI increased during the study period, but no methicillin or vancomycin resistant strains were found. The antimicrobial resistance (AMR) rate was highest in CoNS isolates. CONCLUSION: GPB-BSI was four times more common than Gram-negative BSI in neonates but resulted in lower mortality rate. GBS was the most common pathogen in full-term infants and in EOS. CoNS was the most common pathogen in LOS and infants born very preterm, and the AMR rate was high in these isolates. The increasing trend of S. aureus BSI indicates a need of further investigation.

OBJECTIVES: To analyse the clinical characteristics and risk factors for bloodstream infections (BSIs) caused by carbapenem-resistant Enterobacteriaceae (CRE) in neonates. METHODS: This single-centre, retrospective study included all patients with BSIs admitted to a neonatal intensive care unit between 1 January 2015 and 30 April 2022. The clinical and microbiological data of patients were collected; predictors of 30-day mortality in patients with CRE BSIs were also identified in this study. RESULTS: Among the 224 neonates with Enterobacteriaceae BSIs, 39.29% (88/224) of the patients developed CRE BSIs. The 30-day mortality rate reached up to 21.59% (19/88). The Quick Sequential Organ Failure Assessment score > 2 (odds ratio [OR] and 95% credibility interval [CI]: 3.852 [1.111-13.356], P < 0.05), prior to more than two kinds of antibiotics use (OR and 95% CI: 9.433 [1.562-56.973], P < 0.05), pneumonia (OR and 95% CI: 3.847 [1.133-13.061], P < 0.05), and caesarean section (OR and 95% CI: 2.678 [1.225-5.857], P < 0.05) were independent risk factors associated with CRE BSIs. Moreover, the risk factors for mortality in neonates with CRE BSIs were significantly associated with neonatal Sequential Organ Failure Assessment score > 6 (OR and 95% CI: 16.335 [1.446-184.517], P < 0.05). CONCLUSION: Prior to more than two kinds of antibiotics use, Quick Sequential Organ Failure Assessment score > 2, pneumonia and caesarean section were independent risk factors for CRE BSIs. The Neonatal Sequential Organ Failure Assessment score > 6 was a risk factor for mortality associated with CRE BSIs.

OBJECTIVES: A systematic review with met-analysis was performed to summarise the evidence on the effect of intrapartum azithromycin on maternal and neonatal infections and deaths. SEARCH STRATEGY: PubMed, Scopus and Web of Science databases were searched in March 2023. SELECTION CRITERIA: Randomised controlled trials comparing intrapartum single-dose of azithromycin with placebo. DATA COLLECTION AND ANALYSIS: Maternal infections, maternal mortality, neonatal sepsis, neonatal mortality. We used the random-effects Mantel-Haenszel method to calculate risk ratios (RR) with 95% confidence intervals (95% CI). We assessed risk of bias of the included studies and estimated the evidence certainty using the GRADE approach. MAIN RESULTS: After screening 410 abstracts, five studies with 44 190 women and 44 565 neonates were included. The risk of bias was low in four and had some concerns in one of the studies. The risk of endometritis was 1.5% in the azithromycin group and 2.3% in the placebo group (RR 0.64, 95% CI 0.55-0.75), and the evidence certainty was high. The respective risk for chorioamnionitis was 0.05% and 0.1% (RR 0.50, 95% CI 0.22-1.18; evidence certainty moderate). The wound infection rate was lower in the azithromycin group (1.6%) than in the placebo group (2.5%), RR 0.52 (95% CI 0.30-0.89; moderate certainty evidence). The maternal sepsis rate was 1.1% in the azithromycin group and 1.7% in the placebo group (RR 0.66, 95% CI 0.56-0.77; evidence certainty high). Mortality rates did not show evidence of a difference (0.09% versus 0.08%; RR 1.26, 95% CI 0.65-2.42; moderate certainty evidence). The neonatal mortality rate was 0.7% in the azithromycin group and 0.8% in the placebo group (RR 0.94, 95% CI 0.76-1.16; moderate certainty evidence). The neonatal sepsis rate was 7.6% in the azithromycin group and 7.4% in the placebo group (RR 1.02, 95% CI 0.96-1.09; moderate certainty evidence). CONCLUSIONS: Intrapartum administration of azithromycin to the mother reduces maternal postpartum infections, including sepsis. Impact on maternal mortality remains undecided. Azithromycin does not reduce neonatal sepsis or mortality rates.

Importance: Neonatal sepsis is a leading cause of neonatal mortality. New interventions are needed to decrease neonatal sepsis and mortality in regions with highest burden. Objective: To evaluate the efficacy of intrapartum azithromycin to reduce neonatal sepsis or mortality, as well as neonatal and maternal infections. Design, Setting, and Participants: This double-blind, placebo-controlled, randomized clinical trial enrolled and followed up birthing parents and their infants at 10 health facilities in The Gambia and Burkina Faso, West Africa, between October 2017 and May 2021. Interventions: Participants were assigned at random to receive oral azithromycin (2 g) or placebo (ratio 1:1) during labor. Main Outcomes and Measures: The primary outcome was a composite of neonatal sepsis or mortality, with the former defined based on microbiologic or clinical criteria. Secondary outcomes were neonatal infections (skin, umbilical, eye and ear infections), malaria, and fever; postpartum infections (puerperal sepsis, mastitis), fever, and malaria; and use of antibiotics during 4-week follow-up. Results: The trial randomized 11â¯983 persons in labor (median age, 29.9 years). Overall, 225 newborns (1.9% of 11â¯783 live births) met the primary end point. The incidence of neonatal mortality or sepsis was similar in the azithromycin and placebo groups (2.0% [115/5889] vs 1.9% [110/5894]; risk difference [RD], 0.09 [95% CI, -0.39 to 0.57]), as was the incidence of neonatal mortality (0.8% vs 0.8%; RD, 0.04 [95% CI, -0.27 to 0.35]) and neonatal sepsis (1.3% vs 1.3%; RD, 0.02 [95% CI, -0.38 to 0.43]). Newborns in the azithromycin group compared with the placebo group had lower incidence of skin infections (0.8% vs 1.7%; RD, -0.90 [95% CI, -1.30 to -0.49]) and need for antibiotics (6.2% vs 7.8%; RD, -1.58 [95% CI, -2.49 to -0.67]). Postpartum parents in the azithromycin group had lower incidence of mastitis (0.3% vs 0.5%; RD, -0.24 [95% CI, -0.47 to -0.01]) and puerperal fever (0.1% vs 0.3%; RD, -0.19 [95% CI, -0.36 to -0.01]). Conclusions and Relevance: Azithromycin administered orally during labor did not reduce neonatal sepsis or mortality. These results do not support routine introduction of oral intrapartum azithromycin for this purpose. Trial Registration: ClinicalTrials.gov Identifier: NCT03199547.

BACKGROUND: The use of azithromycin reduces maternal infection in women during unplanned cesarean delivery, but its effect on those with planned vaginal delivery is unknown. Data are needed on whether an intrapartum oral dose of azithromycin would reduce maternal and offspring sepsis or death. METHODS: In this multicountry, placebo-controlled, randomized trial, we assigned women who were in labor at 28 weeks' gestation or more and who were planning a vaginal delivery to receive a single 2-g oral dose of azithromycin or placebo. The two primary outcomes were a composite of maternal sepsis or death and a composite of stillbirth or neonatal death or sepsis. During an interim analysis, the data and safety monitoring committee recommended stopping the trial for maternal benefit. RESULTS: A total of 29,278 women underwent randomization. The incidence of maternal sepsis or death was lower in the azithromycin group than in the placebo group (1.6% vs. 2.4%), with a relative risk of 0.67 (95% confidence interval [CI], 0.56 to 0.79; P<0.001), but the incidence of stillbirth or neonatal death or sepsis was similar (10.5% vs. 10.3%), with a relative risk of 1.02 (95% CI, 0.95 to 1.09; P = 0.56). The difference in the maternal primary outcome appeared to be driven mainly by the incidence of sepsis (1.5% in the azithromycin group and 2.3% in the placebo group), with a relative risk of 0.65 (95% CI, 0.55 to 0.77); the incidence of death from any cause was 0.1% in the two groups (relative risk, 1.23; 95% CI, 0.51 to 2.97). Neonatal sepsis occurred in 9.8% and 9.6% of the infants, respectively (relative risk, 1.03; 95% CI, 0.96 to 1.10). The incidence of stillbirth was 0.4% in the two groups (relative risk, 1.06; 95% CI, 0.74 to 1.53); neonatal death within 4 weeks after birth occurred in 1.5% in both groups (relative risk, 1.03; 95% CI, 0.86 to 1.24). Azithromycin was not associated with a higher incidence in adverse events. CONCLUSIONS: Among women planning a vaginal delivery, a single oral dose of azithromycin resulted in a significantly lower risk of maternal sepsis or death than placebo but had little effect on newborn sepsis or death.

Objetivou-se analisar o perfil epidemiológico e as causas da mortalidade neonatal e infantil, em uma Regional de Saúde, de janeiro/2018 a agosto/2020. Trata-se de pesquisa exploratória, descritiva, transversal, retrospectivo, com abordagem quantitativa. A coleta de dados ocorreu em agosto de 2020, por meio de questionário elaborado pelas pesquisadoras, com base nas declarações de óbito disponibilizadas no Sistema de Informações de Mortalidade. O instrumento abordou as variáveis, sexo, raça, cor, idade da criança, idade materna, escolaridade materna, via de parto, idade gestacional, peso ao nascer, causa do óbito. Os dados foram submetidos à análise estatística descritiva e distribuição de frequência, por meio do Statistical Package for the Social Sciences (SPSS), versão 25.0. Constatou-se o predomínio de óbitos no sexo masculino (56,5%), de raça branca (87,8%), com equivalência entre extremo baixo peso e adequado (31,3%), com a principal causa de óbito por septicemia (13,9%). Quanto aos dados maternos, prevaleceram idade entre 21 e 30 anos de idade (45,2%) com gestação única (85,21%) e parto cesariano (65,2 %). Desses, 47,87% ocorreram no ano de 2018. Analisar os aspectos da mortalidade neonatal e infantil possibilita o planejamento e a readequação de ações no atendimento à saúde da criança, durante o período mais vulnerável e mais crítico dela, contribuindo, assim, para redução do número de óbitos.
This study analyzed the epidemiological profile and the causes of neonatal and infant mortality in a Health Regional Area between January 2018 and August 2020. This is an exploratory, descriptive, cross-sectional, retrospective study with a quantitative approach. Data collection took place during August 2020 through a questionnaire prepared by the researchers, based on the death certificates available in the Mortality Information System. The instrument included the variables of sex, race, color, child's age, mother's age, maternal education, childbirth mode, gestational age, birth weight, cause of death. The data were submitted to descriptive statistical analysis and frequency distribution using the Statistical Package for the Social Sciences (SPSS) version 25.0. There was a predominance of deaths among boys (56.5%), Caucasian (87.8%), with equivalence between extreme low and adequate weight (31.3%), with the main cause of death being septicemia (13.9%). As for maternal data, age between 21 to 30 years old (45.2%) prevailed, and 85.21% had a single pregnancy, with C-section childbirth (65.2%). From these, 47.87% occurred in 2018. It can be concluded that analyzing the aspects of neonatal and child mortality enables the planning and adjustment of actions in child health care during its most vulnerable and most critical period, thus contributing to reducing the number of deaths.

Introducción: La sepsis neonatal (SN) es una infección sistémica que ocurre antes de los 90 días de vida y que representa una amenaza potencialmente mortal. Esta investigación busca describir la tendencia de defunción por SN en Chile, durante el periodo 2016-2020. Materiales y métodos: Estudio descriptivo observacional, que incluyó a niños fallecidos por SN (n=249) en el periodo 2016-2020 en Chile según datos del departamento de estadísticas e información de salud de Chile. Las variables estudiadas fueron: año de fallecimiento, grupo etario, sexo, región y agente etiológico. No se requirió comité de ética. Resultados: El 2020 tuvo la menor tasa de mortalidad por SN (0,17) y el 2017 la mayor (0,31). El grupo etario de 0-2 días de nacido tuvo la mayor tasa de mortalidad (0,07), mientras que el grupo de 27-28 días corresponde a la menor (0,00). La región de Antofagasta tuvo la mayor mortalidad (0,44) y la región de Magallanes la menor (0,11). La tasa de mortalidad promedio en hombres corresponde a 0,12 y en mujeres a 0,10. En el 89,16% de los casos no se identificó el agente etiológico. Discusión: La mayor mortalidad en 2017 podría deberse a una proporción más alta de nacimientos pretérmino en dicho año. La mayor cantidad de defunciones a menor edad cronológica estaría relacionada con su inmadurez inmunológica. La no detección del agente etiológico pudo deberse al bajo rendimiento de los hemocultivos. Sin embargo, faltan más investigaciones acerca de la incidencia y mortalidad por sepsis neonatal.
Introduction: Neonatal sepsis (NS) is a systemic infection that occurs before 90 days of life and represents a life-threatening threat. This research seeks to describe the trend of death by NS in Chile, during the period 2016-2020. Materials and methods: Observational descriptive study, which included children who died due to NS (n=249) in the period 2016-2020 in Chile, according to data from the Department of Statistics and Health Information of Chile. The variables studied were: year of death, age group, sex, region and etiological agent. No ethics committee was required. Results: 2020 had the lowest mortality rate due to NS (0.17) and 2017 the highest (0.31). The age group of 0-2 days of birth had the highest mortality rate (0.07), while the group of 27-28 days corresponds to the lowest (0.00). The Antofagasta region had the highest mortality (0.44) and the Magallanes region the lowest (0.11). The average mortality rate in men corresponds to 0.12 and in women to 0.10. In 89.16% of the cases, the etiological agent was not identified. Discussion: The higher mortality in 2017 could be due to a higher proportion of preterm births in that year. The greater number of deaths at a lower chronological age would be related to their immunological immaturity. The non-detection of the etiological agent could be due to the low yield of the blood cultures. However, more research on the incidence and mortality from neonatal sepsis is lacking.

Sepsis causes high rates of morbidity and mortality in NICUs. The estimated incidence varies between 5 and 170 per 1000 births, depending on the social context. In very low birth-weight neonates, the level of mortality increases with the duration of hospitalization, reaching 36% among infants aged 8-14 days and 52% among infants aged 15-28 days. Early diagnosis is the only tool to improve the poor prognosis of neonatal sepsis. Blood culture, the gold standard for diagnosis, is time-consuming and poorly sensitive. C-reactive protein and procalcitonin, currently used as sepsis biomarkers, are influenced by several maternal and fetal pro-inflammatory conditions in the perinatal age. Presepsin is the N-terminal fragment of soluble CD14 subtype (sCD14-ST): it is released in the bloodstream by monocytes and macrophages, in response to bacterial invasion. Presepsin seems to be a new, promising biomarker for the early diagnosis of sepsis in neonates as it is not modified by perinatal confounding inflammatory factors. The aim of the present review is to collect current knowledge about the role of presepsin in critically ill neonates.

BACKGROUND: Sepsis is a critical medical condition that requires additional diagnostic considerations. Recently, focus has shifted to the diagnosis of sepsis using new markers to overcome the limitations of traditional laboratory diagnostic modalities. Neutrophil CD11b (nCD11b) and monocyteCD14 (mCD14) cell surface antigens have been shown to be useful in such diagnostic consideration. AIM: To investigate the diagnostic, monitoring, prognostic, and predictive roles of nCD11b and mCD14 as sepsis biomarkers in comparison to each other and to traditional laboratory sepsis parameters in order to select the best fit for routine daily use in neonatal intensive care units (NICUs). SUBJECT: The study included 188 neonates from Ain Shams University Hospitals' NICUs, who were divided into two groups: the control group (n = 100) and the sepsis group (n = 88). Highly sensitive CRP (hs-CRP), complete blood count (CBC), blood culture, and nCD11b and mCD14 evaluations were all part of the laboratory sepsis evaluation (done by flow cytometry technology). Positive blood culture results (BACT/ALERT system) confirmed the sepsis diagnosis. Twenty-four enrolled sepsis neonates were subjected to follow-up assessments, and they were divided into two groups based on clinical improvement: improved sepsis and sepsis without improvement. In order to predict performance evaluation, the subjected neonates were reclassified according to their outcome into survivors' and nonsurvivors' group. RESULTS: Sepsis patients had a significant increase in mCD14 MFI values when compared to controls. With sensitivity 75.4 percent, specificity 71.9 percent, efficacy 73.3 percent, and AUC 0.703, mCD14 MFI at cutoff 9.36 could distinguish the presence of septicemia. Significant increases in both mCD14 MFI and nCD11b MFI (P = 0.001) were observed in the severe sepsis/septic shock group compared to the nonsevere sepsis group. The combined measurement of CD14 MFI at cutoff 9.97 and CD14 percent at cutoff 44.7 percent yielded the best predictive performance. CONCLUSION: Sepsis patients had a significant increase in mCD14 MFI comparable to the controls. mCD14 MFI demonstrated better diagnostic, prognostic, and predictive results than nCD11b. hs-CRP outperformed mCD14 and nCD11b in terms of diagnostic efficacy and AUC. In the monitoring of sepsis patients, both mCD14 and nCD11b produced unsatisfactory results. Currently, the routine use of mCD14 or nCD11b as sepsis biomarkers in neonatal ICUs is not justified.

OBJECTIVES: To determine the epidemiology and microbiology of early-onset sepsis (EOS) among very preterm infants using a nationally representative cohort from academic and community hospitals to inform empirical antibiotic guidance, highlight risk factors for infection, and aid in prognostication for infected infants. METHODS: Prospective observational study of very preterm infants born weighing 401 to 1500 g or at 22 to 29 weeks' gestational age from January 2018 to December 2019 in 753 Vermont Oxford Network centers. EOS was defined as a culture-confirmed bacterial infection of the blood or cerebrospinal fluid in the 3 days after birth. Demographics, clinical characteristics, and outcomes were compared between infants with and without EOS. RESULTS: Of 84 333 included infants, 1139 had EOS for an incidence rate of 13.5 per 1000 very preterm births (99% confidence interval [CI] 12.5-14.6). Escherichia coli (538 of 1158; 46.5%) and group B Streptococcus (218 of 1158; 18.8%) were the most common pathogens. Infected infants had longer lengths of stay (median 92 vs 66 days) and lower rates of survival (67.5% vs 90.4%; adjusted risk ratio 0.82 [95% CI 0.79-0.85]) and of survival without morbidity (26.1% vs 59.4%; adjusted risk ratio 0.66 [95% CI 0.60-0.72]). CONCLUSIONS: In a nationally representative sample of very preterm infants with EOS from 2018 to 2019, approximately one-third of isolates were neither group B Streptococcus nor E coli. Three-quarters of all infected infants either died or survived with a major medical morbidity. The profoundly negative impact of EOS on very preterm infants highlights the need for novel preventive strategies.

OBJECTIVE: To provide national-level antibiotic use data from Chinese neonatal intensive care units to inform future antimicrobial stewardship using a large contemporary cohort of preterm infants in China. STUDY DESIGN: This retrospective cohort study enrolled all infants less than 340/7 weeks of gestation admitted to 25 tertiary neonatal intensive care units across China between May 1, 2015, and April 30, 2018. The antibiotic use rate (AUR) was defined as the number of days an infant was prescribed with 1 or more antibiotics divided by the total length of hospital stay. RESULTS: Among 24 597 eligible infants, 21 736 (88.4%) infants received antibiotics. The median AUR was 441 per 1000 patient-days (IQR, 242-692 per 1000 patient-days). The median duration of each antibiotic course was 9 days (IQR, 6-14 days). Overall, 64.6% infants received broad-spectrum antibiotics, with a median broad-spectrum AUR of 250 per 1000 patient-days (IQR, 0-500 per 1000 patient-days), accounting for 70.7% of all antibiotic use days. Overall, 68.7% of all antibiotic use occurred among infants without infection-related morbidities, with a median duration of 8 days (IQR, 6-13 days) for each course. Only 22.9% episodes of culture-negative sepsis were prescribed with antibiotics for 7 or fewer days, and 34.7% were treated with antibiotics for more than 14 days. For early antibiotic use, the median duration of antibiotic therapy within 7 days after birth was 7 days (IQR, 4-7 days). CONCLUSIONS: A high AUR among infants without infections, prolonged antibiotic durations, and excessive use of broad-spectrum antibiotics were the main problems of antibiotic use in Chinese neonatal intensive care units and should be high-impact focuses for future stewardship interventions.
