Clinical Value of Metagenomic Sequencing in Neonatal Sepsis
Neonatal SepsisThis study aimed to enroll 2000 neonatal patients with suspected sepsis or clinical diagnosed sepsis. These patients will undergo both conventional methods and metagenomics sequencing to detect the pathogenic microorganisms of sepsis. The purpose of this study was to assess the clinical value of metagenomics sequencing for the diagnosis and treatment of neonatal sepsis.
Parental Participation on the Neonatal Ward - the neoPARTNER Study
PrematurePremature Birth18 moreObjective: To investigate the effect of FCR as part of the FICare principles during hospital stay, on parental stress at discharge in parents of preterm or ill infants admitted to the neonatal ward for >7 days as compared to standard medical rounds (SMR) without parents as part of standard neonatal care (SNC).
Antibiotic Therapy for Early Onset Neonatal Sepsis
Early Onset Neonatal SepsisAntibiotic therapy for early onset neonatal sepsis recommended by international guidelines and relevant studies is only kind of treatment regimen that penicillin G/ penicillin/ampicillin combined with gentamicin as the first-line treatment regimen. However, it is not applicable to the clinical practice in many countries and regions. We aim to study efficacy and safety of antibiotics in the treatment of early onset neonatal sepsis.
Smart Discharges for Mom & Baby
Maternal SepsisNeonatal SepsisThis study aims to build a predictive algorithm that identifies mother-newborn dyads most at risk of death or complications in the 6 weeks after birth. The investigators will conduct a multi-site cohort study with 7,000 dyads in Uganda and engage with local stakeholders (e.g., patients, healthcare workers, and health policy-makers) to develop an evidence-based bundle of interventions that address key practice gaps and the critical factors leading to death and complications in these dyads. In the investigator's epidemiological study of post-delivery post-discharge outcomes in 3,236 dyads in Uganda (2017-2020), results indicated that most newborn and maternal readmissions were due to infectious illness (i.e. sepsis, surgical site infections, malaria), and primarily occurred early in the post-discharge period. Thus, the focus of this study will be identifying interventions that target these common and early outcomes, for both mothers and newborns, using WHO recommendations, patient and caregiver experiences, and stakeholder recommendations. If successful, results will inform the next steps of this project, which is the external validation of the model and clinical evaluation of a personalized approach to improving health outcomes and health-seeking behaviour for mothers and newborns.
Performance of Interleukin-27 Cord Blood Level as A Biomarker Predicating Early Onset Neonatal Sepsis...
Neonatal SepsisEarly-OnsetNeonatal sepsis still considered as one of the major causes of mortality and morbidity during the neonatal period due to high vulnerability of that age group. The blood culture is considered as the gold standard for diagnosis of bacterial sepsis, however in early onset neonatal sepsis (EONS) the inability to isolate a microbial pathogen does not exclude sepsis. The reason behind the high number of culture-negative cases is not clear and might be attributed to low levels of bacteremia or small volumes of blood obtained from sick infants. Also maternal antibiotic treatment before or during delivery may theoretically mask detection of bacteremia in the newborn. In addition these cultures have a 48-72 hours delay to obtain results. Therefore, the combination of clinical assessment and laboratory biomarkers currently are the bases for diagnosis of neonatal sepsis. Recently interleukin-27 (IL-27) has been looked at as another candidate biomarker in the serum for diagnosis of sepsis in both adult and children. Interleukin-27 (IL-27), a novel member of the IL-12 family, was first discovered in 2002. IL- 27 is primarily synthesized by antigen-presenting cells, and it is widely expressed in a myriad of cells, including placental trophoblast cells. Although multiple studies have reported IL-27 as an essential regulator of immune response and inflammation, its precise role in the immune response is still disputable. Conventionally, IL-27 has been envisaged as a potent promoter of inflammation. When first discovered, it was characterized as a promoting factor in the rapid initiation of inflammatory responses, processing the ability to stimulate the rapid expansion of naïve CD4+T and then the production of IFN-?, which has been demonstrated by various subsequent studies. The aim of this study was to evaluate the usage of elevated IL-27 in cord blood as an early predictor biomarker for EONS.
Presepsin to Safely Reduce Antibiotics in Preterm Infants
Early-Onset Neonatal SepsisIn the Netherlands, more than 85% of the preterm infants born <32 weeks gestational age get antibiotics directly after birth because of the risk of infection with a bacteria. However, only 1 in 70 of these preterm babies actually has a bacterial infection. The use of antibiotics after birth can lead to problems on short term (bowel infection, infection with a bacteria later on or death) or long term (asthma, allergy, obesity). The goal of the PRESAFE trial is to investigate whether addition of a biomarker (presepsin) to the Dutch early-onset neonatal sepsis (EOS) guideline safely reduces unnecessary empirical antibiotic exposure after birth in preterm infants born before 32 weeks gestational age. In this 874-subject multicenter, randomized clinical trial with a concurrent observational cohort, the hypothesis to be tested is that by adding presepsin to the national guideline the amount of unnecessary empirical antibiotic exposure after birth will be reduced with at least 30% without increase in infants with untreated sepsis. The study targets a population of clinical stable very preterm infants with risk factors for eary-onset neonatal sepsis. Antibiotic administration after birth is started to pre-emptively treat EOS. By adding a presepsin-guided step to the Dutch EOS guideline for those infants qualifying for antibiotic treatment, it is assumed that the rate of antibiotic administration can be reduced. However, it is imperative that this reduction in antibiotics is not outweighed by an increase in (culture proven) EOS. Therefore, the co-primary outcomes of the study are: 1) the incidence of culture-proven EOS (non-inferiority) and 2) unnecessary antibiotics prescription i.e. antibiotic administration for ≤ 3 days when started within the first 72 hours after birth (superiority). Secondary outcomes include sepsis-related severity of illness, total number of antibiotic days when started < 72 hours after birth, and the composite outcome of necrotizing enterocolitis (NEC), late-onset sepsis (LOS), or death until discharge from the initial hospital.
PROcalcitonin and Presepsin-guided Decision for Antibiotic Prophylaxis of EOS
Early-Onset Neonatal SepsisThe goal of this randomized controlled study is to compare the outcome of preterm infants who will receive the standard antibiotic prophylaxis for EOS or Procalcitonin/Presepsin-guided antibiotic prophylaxis of early onset sepsis (EOS). The main question it aims to answer is: • Does Procalcitonin/Presepsin-guided antibiotic prophylaxis of (EOS) increase survival without major morbidities, including IVH >3 grade, PVL, ROP >3 grade in either eye, NEC >2 grade, BPD, or LOS. Infants with gestational age between 25+0 and 31+6 weeks of gestation or a birth weight <1500 g will be eligible for enrollment in the study. Participants will be randomized to receive standard antibiotic prophylaxis for EOS (standard group) or to receive antibiotic prophylaxis for EOS on the basis of PCT/P-SEP measured within 3 h of life (intervention group).
THE VALUE OF INTERLEUKIN 6 AS A DIAGNOSTIC MARKER IN NEONATAL SEPSIS
NEONATAL SEPSISNeonatal sepsis is a leading cause of neonatal mortality and continues to be a formidable problem for neonatologists and pediatricians world over. The prevalence of neonatal sepsis varies in different countries; in developed countries it is 1 to 10 cases per 1000 live births and in developing countries the incidence of neonatal septicemia increases to 49 to 170 cases per 1000 live births. The normal fetus is sterile until shortly before birth as the placenta and amniotic sac are highly effective barriers to infections. At birth, the newborn loses the protection afforded to it in the uterus and gets exposed to the microbial world.Neonatal sepsis is broadly divided into two types according to age of onset: Early-onset sepsis (<72 Hrs) and late-onset sepsis (≥72 hrs-28 days). Early-onset sepsis is acquired during fetal life, delivery, or at the nursery.Bacterial organisms causing NS may differ among countries, however, in most developing countries, gram-negative bacteria remain the major source of infection.To date, blood culture is the gold standard test for diagnosing sepsis, but it has some inherent limitations. It takes at least three or five days to be decisive and can be mistakenly negative because antibiotics are initiated empirically before collection and a well-developed microbiology laboratory is required.CRP is one of the most widely studied and applied acute phase proteins clinically, which can be induced by pre-inflammatory factor interleukin-6 (IL-6) to synthesize by liver cells, and it starts to rise in 12-24 hours of inflammatory response and reaches its peak at 48 hours.Interleukin-6 (IL-6) is a pleiotropic cytokine expressed by different cells in response to infections.
Predicting EONS in PPROM Patients
PPROMEarly-Onset Neonatal SepsisAn EONS occurred in nearly 14-22 % of the preterm infant of pregnant women with PPROM. To this day no risk prediction is established. The main aim of this pilot study is generating primary data with a focus on the vaginal microbiome to set-up a prospective, multi-centre trial investigating the role of the vaginal microbiome for future EONS risk prediction. The planned PEONS pilot trial is subdivided in three Work packages: Recruitment, sample collection and routine clinical diagnostics Microbiome analysis by 16S rRNA Microbiome/ Metagenome analysis by "Nanopore" (proof-of-principle) and will enroll women with a PPROM event hospitalized between 22+0 and 34+0 weeks of gestation and neonates with signs of EONS (Subgroup 1) and without signs of EONS (Subgroup 2).
The Volume of Blood Submitted for Culture in Neonates - a Multicentre Quality Improvement Initiative....
Neonatal SepsisThe study will examine if introducing the practice of checking the volume of blood culture samples in neonates by bedside weighing will improve the sensitivity of the test and increase confidence in negative results affecting the rate of extended antibiotic treatment in neonates with negative blood cultures.
