Novel Mechanisms and Approaches to Treat Neonatal Sepsis
Complication of PrematurityImmunologic Deficiency SyndromesMortality related to neonatal sepsis exceeds 1 million deaths worldwide; the highest risk of mortality is in preterm neonates, especially low birth weight (LBW), and very low birth weight (VLBW) neonates. The estimated cost of caring for these patients is approximately $700 million in the US alone. In an effort to help mature the neonatal immune system, several adjuvant therapies have been studied; however, none have been implemented in clinical practice. One of the most frequently considered targets for adjuvant therapy is toll-like receptors (TLRs). TLRs detect conserved molecular products of microorganisms (lipopolysaccharide (LPS), and initiate immunity and inflammation. Early adjuvant administration in VLBW infants may be a viable approach to reducing the incidence of early and late sepsis. This research study will characterize immune genomic expression and functional capacity at the time of birth in both term and preterm neonates and determine what effects, if any, that adjuvants have on this function. Additionally, this study will seek to determine if immune function correlates with certain microbiota.
Neurodevelopmental Outcomes After Suspected or Proven Sepsis: Secondary Analysis of INIS Trial Database...
Neonatal SepsisNeonatal sepsis is an important determinant of adverse neurodevelopmental outcome. The investigators seek to investigate whether neurodevelopmental outcome following neonatal sepsis differs according to whether or not the diagnosis is confirmed by culture. In a secondary analysis of all 3493 infants included in the International Neonatal Immunotherapy Study (INIS) randomized controlled trial of intravenous immunoglobulin for neonatal sepsis, the investigators will evaluate neurodevelopmental outcomes according to whether or not the sepsis was culture-proven. The primary outcome is death or major disability at two years. In secondary analyses the investigators will determine neurodevelopmental outcomes according to the causative organism identified. Greater understanding of the impact of culture-positivity on long-term outcomes in the setting of clinical neonatal sepsis is essential to better inform parents about the future prospects of their child and to guide patient follow-up.
Infection, Sepsis and Meningitis in Surinamese Neonates
Neonatal SepsisNeonatal Infection1 moreSuriname is a small developing country in South America with a population of half a million people. Early neonatal death in Suriname is high with 16 per 1000 live births. Unpublished data from the Suriname Perinatal and Infant Mortality Survey estimate contribution of infection to early neonatal mortality at 25% (4 per 1000 live births) of all deaths. In comparison, incidence rates of neonatal sepsis alone are 3.5 per 1000 live births. These numbers indicate an increased burden of neonatal infection in Suriname versus the U.S. In any case about 40 newborns that die each year of infection are a huge loss, also considering the small Surinamese community. Despite this overall idea on the impact of infectious disease in Surinamese neonates exact information regarding incidence, type of infection (e.g., localized, viral, early-onset or late-onset sepsis), risk factors (e.g., insufficient antenatal care, maternal Group B-Streptococcus status), etiology, microbial causes, morbidity, antibiotic treatment (type and duration), and epidemiological determinants (e.g., gestational age, sex, ethnicity) are lacking. From a clinical perspective, there is still a challenge to identify neonates with infection. Neonates are often admitted with ambivalent clinical symptoms and receive preventive antibiotics that are costly, promote pathogen-resistance, and have negative long-term effects (i.e., on the development of the intestinal bacterial flora). Currently, assessment of blood leukocyte or trombocyte counts and levels of CRP are insufficiently sensitive to be used as biomarkers, while confirmation of actual sepsis or meningitis by positive culture results is relatively rare (0.5-3% in the United States). This complicates decisions on duration of antibiotic treatment and hospitalization significantly, while no other biomarkers exist. The circulating isoforms of adhesion molecules (cAMs), which mediate interactions of leukocytes with the vascular endothelium, have been proposed as biomarkers for infection and sepsis. During infection they accumulate in the bloodstream as a result of shedding, which represents their removal from cell surfaces of endothelial cells and leukocytes by enzymes called sheddases. Recently, we have reviewed mechanisms behind shedding of cAMs in neonatal, pediatric and adult sepsis. The shedding process reflects a critical and active process in orchestrating interaction between leukocytes and the endothelium for an effective host response, while minimizing collateral tissue damage. As a result, both plasma levels of cAMs and their sheddases are subject to change during infection and sepsis. Additionally, compelling, albeit limited, data suggest changes of levels of cAMs in CSF in adult and pediatric meningitis. To date, some evidence exists of changes in levels of cAMs during malaria (in children from Malawi) and sepsis, although not sensitive enough to predict outcomes in the clinic. Those levels have never been assessed simultaneously with levels of their sheddases in blood or CSF as a diagnostic tool. We propose that this combined approach may provide more detailed information about the extent of inflammatory activation in neonates.While a balance in levels is maintained under resting conditions or mild (local) infection, it may be perturbed during sepsis or meningitis . Thus, simultaneous measurement of these levels could promote early identification of infection, and may even distinguish between mild infection, systemic infection or meningitis. Currently, manufacturers are rapidly developing Luminex® technology as an advanced, fast, high-throughput and clinically feasible bedside tool for such an approach. We hypothesize that incidence rates of neonates with infection in Suriname are high. We further hypothesize that, upon signs of infection, the simultaneous measurement of cAMs and their SEs in serum and CSF discriminates between infected and non-infected neonates. We aim to: 1) identify and follow neonates at the Academic Hospital Paramaribo with signs of infection to establish incidence rates of infection, and 2) investigate diagnostic potential of our proposed biomarker combination in these neonates for infection, type of infection (e.g., local (mild), sepsis or meningitis) and outcomes.
Hepcidin Levels in Preterm Infants
Preterm InfantsAnemia of Prematurity1 moreA recently isolated peptide hormone, hepcidin, is thought to be the principal regulator of iron homeostasis. Hepcidin acts by limiting intestinal iron absorption and promoting iron retention in reticuloendothelial cells. The aims of this study were to determine serum hepcidin levels in preterm infants who receive blood transfusion and preterm infants having sepsis, in order to assess possible relationships between hepcidin and serum iron, serum ferritin,in iron load situations.
CD64 Measurement in Neonatal Infection and Necrotising Enterocolitis
Neonatal SEPSISEnterocolitis1 moreBacterial infections are a major cause of death in newborn infants. And are linked to complications including: sepsis (an over exaggerated immune response to infection) and necrotising enterocolitis (a potentially fatal inflammatory bowel disease). Detecting infections at an early stage is difficult in newborns as the signs and symptoms can be non-specific, the most commonly used lab test is to culture a sample of blood, urine or spinal fluid to try and grow and identify any bacteria that is present; however these tests take 24-48 hours to give results, and this means that neonates who present with signs of infection are prescribed broad spectrum antibiotics whilst results are obtained. The lack of a test that can detect infection at an early stage and give rapid results is one of the major problems in the diagnosis and management of infection in newborns. This study will investigate neutrophils, which are white blood cells that are important in fighting infection. When neutrophils detect and infection they become activated, and produce a protein called CD64 (a cell marker) on their surface, and it is this protein that we want to measure. Neutrophils produce the CD64 protein within 1 hour of first detecting an infection, so we could hopefully detect and treat infections much quicker. The hypothesis this study will test are: Does neutrophil membrane CD64 measurement provide a highly sensitive and specific marker of infection in neonates AND: Does neutrophil membrane CD64 measurement provide a highly sensitive and specific marker of NEC in neonates
