Neutrophil Extracellular Traps and Neonatal (PV4991) & Pediatric Sepsis (PV5063)
Studie Overzicht
Gedetailleerde beschrijving
Severe infection resulting in sepsis is recognized as a leading cause of morbidity and mortality worldwide (Stehr and Reinhart, 2013). The incidence of sepsis in developed nations has been increasing while overall mortality is decreasing, but still remains around 30% (Mayr et al., 2014). Moreover, morbidity in survivors is often functionally devastating, and may include neurological impairment, chronic organ dysfunction, increased days admitted to hospital, and high rates of mortality postdischarge (Prescott et al., 2014). Emotional, social, and financial costs to individuals and health care systems are immense (Brun-Buisson et al., 2003).
Neutrophils are the first line of innate immune defense against infectious agents. In addition, neutrophils' ability to eliminate pathogens by phagocytosis and/or degranulation, it has recently been demonstrated that neutrophils can bind to and kill a wide range of microorganisms by forming neutrophil extracellular traps (NETs) (Brinkmann et al., 2004). This novel mechanism consists of the release of web-like structures of DNA decorated with histones and antimicrobial proteins, known as NETs. Microbes are immobilized in these traps, which contain a lethal concentration of antimicrobial agents killing a broad range of microorganisms, including gram-negative and gram-positive bacteria, fungi, viruses, and protozoa (Brinkmann et al., 2004, Fuchs et al., 2010, Camicia et al., 2014).
The role of NETs in pediatric infection is not well understood. We hypnotize that children are capable of forming NETs and that NETosis plays an important role in pediatric sepsis. This study is designed to assess the role of neutrophil extracellular traps (NETs) in neonatal and pediatric sepsis as well as to evaluate markers of NETs formation as early predictors of neonatal and pediatric sepsis.

Actual Sepsis
For infants below 44 weeks inclusive of corrected age clinical sepsis is defined, according to the Expert Meeting on Neonatal and Pediatric Sepsis (Report on the Expert Meeting on Neonatal and Pediatric Sepsis - 8 June 2010, EMA London). Confirmed sepsis is defined as positive culture for pathogens in a sample from a normally sterile site and at least one laboratory sign or clinical sign (not shown) For children above 44 weeks corrected age clinical sepsis is defined according to the Goldstein criteria (Goldstein et al, 2005). Confirmed sepsis: positive culture for pathogens in a sample from a normally sterile site and at least one laboratory sign or clinical sign (not shown) |
