ObjectiveTo define the susceptibilities of the common causative pathogens of neonatal sepsis in the UK.DesignRetrospective analysis of the prospectively collected neonIN infection surveillance network data between 2005 and 2014.Setting30 neonatal units in the UK.PatientsNewborns admitted to participating neonatal units who return a positive blood, cerebrospinal fluid or urine culture and are treated with at least 5 days of appropriate antibiotics.Results1568 isolates with recorded antimicrobial data were collected including 328 early-onset sepsis (EOS) isolates and 1240 late-onset sepsis (LOS) isolates. The majority of EOS pathogens (>92%) were susceptible to the four empirical commonly used antimicrobial combinations (eg, 93% for benzylpenicillin/gentamicin), while LOS pathogens demonstrated higher levels of resistance (eg, 89% for flucloxacillin/gentamicin). Among infants<1500 g and <32 weeks gestation, an amoxicillin/gentamicin combination demonstrated a trend towards improved coverage of EOS isolates than benzylpenicillin/gentamicin (93% vs 86%, p=0.211).ConclusionsThis analysis provides insights into the patterns of antimicrobial resistance among UK neonatal pathogens. These data will inform areas of future research and can be used to update national evidence-based guidelines on antimicrobial usage.

ObjectiveTo describe the epidemiology of neonatal infection over the past decade in UK neonatal units.DesignRetrospective analysis of prospectively collected infection surveillance network data from 2005 to 2014.Setting30 neonatal units in the UK.PatientsNewborns on participating neonatal units who had a positive blood, cerebrospinal fluid or urine culture and were treated with at least 5 days of appropriate antibiotics.Results2171 episodes of neonatal infection in 1922 infants were recorded. The incidence of infection was 6.1/1000 live births and 48.8/1000 neonatal admissions (2.9 and 23.5 respectively if coagulase-negative staphylococci (CoNS) cultures excluded). The incidence of infection showed a statistically significant reduction over time with reductions in the rates of both early-onset sepsis (EOS) and late-onset sepsis (LOS).The majority of episodes (76%) represented LOS (diagnosed > 48 hours after birth), and infection was more common in premature (<37 weeks gestation) and low birth weight (<2500 g) neonates (84% and 81%, respectively). Commonly identified pathogens included group B streptococci (43%) and Escherichia coli (18%) for EOS, while E. coli (15%), Staphylococcus aureus (14%) and CoNS were prominent causes of LOS.ConclusionsThis paper describes the epidemiology of neonatal infection in the UK over the past decade. These data enable benchmarking of practice and inform areas of future research and guideline development. The results support the hypothesis that the introduction of infection prevention care bundles and antibiotic stewardship programmes in the UK has reduced the burden of LOS.

ObjectiveTo describe the epidemiology of neonatal infections and of antimicrobial use in Greek Neonatal Units (NNUs) in order to develop national, evidence-based guidelines on empiric antimicrobial use for neonatal sepsis in Greece.DesignRetrospective analysis of prospectively collected infection surveillance data from 2012 to 2015, together with a Point Prevalence Survey (PPS) on antimicrobial use and the collection of data on local empiric antimicrobial policies.Setting16 NNUs in Greece participating in the neonIN infection surveillance networkPatientsNewborns in participating NNUs who had a positive blood, cerebrospinal fluid or urine culture and were treated with at least 5 days of antibiotics.Results459 episodes were recorded in 418 infants. The overall incidence of infection was 50/1000 NNU-admissions. The majority of episodes were late-onset sepsis (LOS) (413, 90%). Coagulase-negative Staphylococci (80%) were the most common Gram-positive organisms causing LOS and Klebsiella spp (39%) the most common Gram-negative. Nearly half (45%) of the Klebsiella spp were resistant to at least one aminoglycoside. The PPS revealed that 196 of 484 (40%) neonates were on antimicrobials. The survey revealed wide variation in empiric antimicrobial policies for LOS.ConclusionsThis is the largest collection of data on the epidemiology of neonatal infections in Greece and on neonatal antimicrobial use. It provides the background for the development of national evidence-based guidelines. Continuous surveillance, the introduction of antimicrobial stewardship interventions and evidence-based guidelines are urgently required.

Abstract ObjectivesTo describe pathogens distribution and their antimicrobial resistance (AMR) of neonatal bloodstream infections (BSIs) at 25 NICUs in eastern China, 2016-2019.Study designWe conducted a multicentre retrospective descriptive analysis of all positive blood cultures collected at 25 NICUs of tertiary hospitals between January 1, 2017, and December 31, 2019. ResultsFrom 1 January 2017 to 31 December 2019, a total of 1092 pathogenic bacteria isolates were met inclusion criteria among 66516 specimens. 349 (32%) isolates were responsible for early-onset sepsis (EOS), 702 (64.2%) hospital-acquired late-onset sepsis (HALOS), and 41(3.8%) community-acquired late-onset sepsis (CALOS). The majority isolates causing EOS (198/349, 56.7%) and HALOS (437/702, 62.2%) were gram-negative bacteria; The most frequent pathogens causing EOS were Escherichia coli (95/349, 27.2) and group B streptococcus (GBS; 51/349, 14.6%). E coli were primarily identified among preterm infants (58/95, 61.1%) with GBS primarily among term infants (43/51, 84.3%). GBS and Staphylococcus aureus were responsible for 46.3% (19/36) and 41.5% (17/36) of episodes of CALOS. Isolates causing HALOS were more often resistant than isolates causing EOS and CALOS. K. pneumoniae (196/702, 27.9%) as the most common isolates responsible for HALOS were more likely to be resistant to third-generation cephalosporins (124/196, 63.3%), gentamicin (41/196, 20.9%) and carbapenem (26/196, 13.3%). Conclusions Escherichia coli, K. pneumonia and GBS were the most common pathogens in EOS, HALOS and CALOS, respectively. High AMR in K. pneumoniae causing HALOS warrants continued study and devise measures to prevent it in low-income and middle-income countries.

Introduction: India has the highest incidence of clinical sepsis i.e.17,000/ 1,00,000 live births. In Neonatal sepsis septicaemia, pneumonia, meningitis, osteomyelitis, arthritis and urinary tract infections can be included. Mortality in the neonatal period each year account for 41% (3.6 million) of all deaths in children under 5 years and most of these deaths occur in low income countries and about one million of these deaths are due to infectious causes including neonatal sepsis, meningitis, and pneumonia. In early onset neonatal sepsis (EOS) Clinical features are non-specific and are inefficient for identifying neonates with early-onset sepsis. Culture results take up to 48 hours and may give false-positive or low-yield results because of the antenatal antibiotic exposure. Reviews of risk factors has been used globally to guide the development of management guidelines for neonatal sepsis, and it is similarly recommended that such evidence be used to inform guideline development for management of neonatal sepsis. Material and Methods: This study was carried out using institution based cross section study . The total number neonates admitted in the hospital in given study period was 644, of which 234 were diagnosed for neonatal sepsis by the treating pediatrician based on the signs and symptoms during admission. The data was collected: Sociodemographic characteristics; maternal information; and neonatal information for neonatal sepsis like neonatal age on admission, sex, gestational age, birth weight, crying immediately at birth, and resuscitation at birth. Results: Out of 644 neonates admitted 234 (36.34%) were diagnosed for neonatal sepsis by the paediatrician based on the signs and symptoms during admission. Of the 234 neonates, 189 (80.77%) infants were in the age range of 0 to 7 days (Early onset sepsis) while 45 (19.23%) were aged between 8 and 28 days (Late onset sepsis). Male to female ratio in our study was 53.8% and 46% respectively. Out of total 126 male neonates 91(72.2%) were having early onset sepsis while 35 (27.8%) were late onset type. Out of total 108 female neonates 89(82.4%) were having early onset sepsis while 19 (17.6%) were late onset type. Maternal risk factors were identified in 103(57.2%) of early onset sepsis cases while in late onset sepsis cases were 11(20.4%). Foul smelling liquor in early onset sepsis and in late onset sepsis was 10(5.56%) and 2 (3.70%) respectively. In early onset sepsis cases maternal UTI, Meconium stained amniotic fluid, Multipara and Premature rupture of membrane was seen in 21(11.67%), 19 (10.56%), 20(11.11%) and 33 (18.33%) cases respectively. In late onset sepsis cases maternal UTI, Meconium stained amniotic fluid, Multipara and Premature rupture of membrane was seen in 2 (3.70%), 1(1.85%), 3 (5.56%) and 3 (5.56%) cases respectively. Conclusion: Maternal risk identification may help in the early identification and empirical antibiotic treatment in neonatal sepsis and thus mortality and morbidity can be reduced.

Previous studies suggested that supplemental bovine lactoferrin (BLF) given to preterm infants (<32 weeks gestation) may reduce late onset sepsis (LOS) and necrotising enterocolitis (NEC), but have been underpowered. The Enteral Lactoferrin in Neonates (ELFIN) study, performed in the United Kingdom (UK), aimed to further address this issue with a well powered double blinded placebo controlled trial of >2200 preterm infants. ELFIN did not demonstrate a reduction in LOS or NEC, or several other clinically important measures. 316 (29%) of 1093 infants in the intervention group developed late-onset sepsis versus 334 (31%) of 1089 in the control group with an adjusted risk ratio of 0·95 (95% CI 0·86–1·04; p=0· 233). Reasons for the differences in ELFIN trial results and other studies may include population differences, the routine use of antifungals in the UK, timing of administration of the lactoferrin in relation to disease onset, or specific properties of the lactoferrin used in different trials. Further exploration is being undertaken in the UK NIHR funded Mechanisms Affecting the Guts of Preterm Infants in Enteral feeding trials (MAGPIE) study, for which results should be available soon.

BACKGROUND Septicaemia is a leading cause of morbidity and mortality in neonates. Antimicrobial prescription for neonatal septicaemia (NS) should be wisely used depending on the regional spectra of infecting microbes and their antimicrobial resistance (AMR) patterns which vary over time, place and host factors. METHODS This was a descriptive cross-sectional study conducted from January 2017 to June 2017 among 102 cases of NS admitted in neonatal intensive care units (NICU). Demographic data of the concerned neonates was collected through a predesigned checklist. Blood collected from neonates was processed for culture and sepsis screen. Antimicrobial susceptibility testing was performed for the cultured isolates and phenotypic AMR patterns were observed. RESULTS Most of the studied neonates had subnormal birth weight (86). Blood culture showed predominance of gram-negative bacilli (GNB) among which Klebsiella pneumoniae was the most common followed by Burkholderia cepacia complex. Coagulase negative staphylococcus species (CoNS) was most numerous among the cultured gram-positive cocci (GPC). Candidemia of late onset was confirmed in 25 neonates. Early onset sepsis was predominantly caused by GNB (29 / 31) predominated by Klebsiella pneumoniae. Multi drug resistant (MDR) pathogens viz., extended spectrum beta-lactamase (ESBL) producing GNB, carbapenem resistant-GNB (CR-GNB) and methicillin resistant staphylococcus (MRS) phenotypes were notably prevalent. CONCLUSIONS Multidrug resistant microorganisms are notably prevalent in neonatal septicaemia. In clinically suspected very sick septicaemic neonates not showing much improvement with guideline-led empirical antimicrobial therapy, an early antibiogram guided change over to meropenem and amikacin or even to colistin in case of reported carbapenem resistance, is highly recommended.

ObjectiveDetermine risk of death or neurodevelopmental impairment (NDI) in infants with late-onset sepsis (LOS) versus late-onset, antibiotic-treated, blood culture-negative conditions (LOCNC).DesignRetrospective cohort study.Setting24 neonatal centres.PatientsInfants born 1/1/2006–31/12/2014, at 22–26 weeks gestation, with birth weight 401–1000 g and surviving >7 days were included. Infants with early-onset sepsis, necrotising enterocolitis, intestinal perforation or both LOS and LOCNC were excluded.ExposuresLOS and LOCNC were defined as antibiotic administration for ≥5 days with and without a positive blood/cerebrospinal fluid culture, respectively. Infants with these diagnoses were also compared with infants with neither condition.OutcomesDeath or NDI was assessed at 18–26 months corrected age follow-up. Modified Poisson regression models were used to estimate relative risks adjusting for covariates occurring ≤7 days of age.ResultsOf 7354 eligible infants, 3940 met inclusion criteria: 786 (20%) with LOS, 1601 (41%) with LOCNC and 1553 (39%) with neither. Infants with LOS had higher adjusted relative risk (95% CI) for death/NDI (1.14 (1.05 to 1.25)) and death before follow-up (1.71 (1.44 to 2.03)) than those with LOCNC. Among survivors, risk for NDI did not differ between the two groups (0.99 (0.86 to 1.13)) but was higher for LOCNC infants (1.17 (1.04 to 1.31)) compared with unaffected infants.ConclusionsInfants with LOS had higher risk of death, but not NDI, compared with infants with LOCNC. Surviving infants with LOCNC had higher risk of NDI compared with unaffected infants. Improving outcomes for infants with LOCNC requires study of the underlying conditions and the potential impact of antibiotic exposure.

AbstractUnspecific symptoms and rapid development of sepsis up to septic shock from systemic inflammatory response syndrome (SIRS) are well-known, important issues in neonatology. A common cause is the infection by Streptococcus agalactiae (Group B Streptococcus [GBS]) or Escherichia coli, which contributes significantly to neonatal morbidity and mortality. Whereas early-onset sepsis is normally derived from mother during birth, late-onset sepsis can be transmitted by the environment. Management of neonatal sepsis includes the maintenance of cardiovascular and pulmonary function besides antibiotic therapy. Due to the fact that until today, there are no reliable screening tests for detecting early sepsis, clinical assessment is considered to be of utmost importance.

Background:Neonatal sepsis is the leading cause of newborn mortality and morbidity worldwide. The spectrum of microorganisms shows wide variation in different regions of the world and also in different hospitals of the same region. In this study we have tried to find out the common bacterial organisms causing neonatal sepsis in our region and their antibiotic susceptibility. Method: It is a hospital based observational study conducted in one of the busiest hospitals of Jorhat over a period of 18 months. Blood culture reports of all patients were traced from the hospital laboratory data. Positive culture reports for bacterial sepsis were studied and analysed statistically. Result:Total 602 blood cultures were performed during the study period out of which 46(7.6%) were bacterial culture positive. Twenty-seven(59%) were Early Onset sepsis and 19(41%) were Late onset sepsis. Male-female ratio was 1.7:1. Most common organism causing bacterial sepsis was Klebsiella Pneumoniae(28%), second was Acinetobacter baumani(22%), third was Staphylococcus aureus (20%), followed by Enterococcus (17%), E coli (9%) and finally CoNS(4%). Twenty-seven(59%) were gram positive organisms (67% caused EONS and 33% caused LONS)and 19(41%) were Gram Negative(58% caused EONS and 42% caused LONS). Levofloxacin had highest sensitivity to all the microorganisms. Conclusion:Neonatal sepsis can be treated with judicious use of antibiotics by studying the common microbial strains in the region and their antimicrobial susceptibility. Antibiotic stewardship should be stressed upon in every institution to protect patients from harm caused by unnecessary antibiotic use and combat the most dangerous threat of antibiotic resistance to the world.

Neonatal sepsis is a major cause of mortality and morbidity in newborn. The spectrum of bacteria which causes neonatal sepsis varies in different parts of the world. The organisms responsible for early onset and late onset sepsis are different. The objective of the study was undertaken to determine the pattern of bacterial isolates responsible for early and late onset neonatal sepsis. A prospective descriptive study over the period of one year was conducted at the Department of Neonatal Intensive care unit of Ad-din Women’s Medical College and Hospital, Dhaka, Bangladesh.Organisms were isolated from 8.7% of collected blood samples. The male female ratio of culture proven sepsis was 1.7:1. More than half (52.8%) of the evaluated neonates were preterm. & 56.3% had low birth weight. The gram positive and gram negative bacteria accounted for 24.1% and 75.9% of the isolates respectively. Around three fourth of the neonates (75.8%) presented with early onset sepsis, while 24.2% presented with late onset sepsis. Acinetobacter was the most common pathogen both in early onset (70%) and late onset (30%) sepsis. Pseudomonas (89.4%) was the second most common pathogen in early onset sepsis. Total mortality rate was 5.7%. Pre term, low birth weight and gram negative sepsis contributes majority of mortality.Gram negative organism especially Acinetobacter found to be commonest cause of sepsis. Pseudomonas was second most common but contributed highest in late onset sepsis and neonatal death due to sepsis.
