Filter by:A randomized, double blind, placebo controlled clinical trial was conducted in the neonatal high care unit of Tygerberg Children's Hospital (TBCH) Cape Town, South Africa for the period July 2011 to August 2012. The primary objective of the study was to assess the effect of probiotics on the incidence of NEC in high risk infants born to HIV-positive and HIV-negative women. Throughout the study period, the standard of care protocol consisted of one dose (5 drops) probiotic/placebo daily for 4 weeks (28 days). This provided the study group with L. rhamnosus GG (0.35 x 109 colony-forming units [CFU]) and B. infantis (0.35 x 109 CFU) daily. The control group received placebo consisting of medium chain triglyceride (MCT) oil. Supplementation of the probiotic/placebo was initiated when enteral feeds started. Probiotic/ placebo supplementation was delayed/ halted in the event of: the infants being nill per os (NPO); when a query Necrotizing Enterocolitis (NEC) was suspected the infant continued with treatment until a confirmed a positive diagnosis of NEC I was made through abdominal X-ray; if the infant remained a query NEC and was NPO the infant did not receive probiotics/ placebo until the enteral feeds were commenced again. Supplementation was discontinued when HIV-exposed infants had a positive polymerase chain reaction (PCR) result on day 14 of life. All study participants received human breast milk. Both the probiotics and placebo were mixed with the mothers own breast milk or donor breast milk before administration via the orogastric tube or orally. The probiotic/ placebo was added to the breast milk by the researcher and two research assistants who were blinded and not involved in the routine care of the infants. Participants exited the study on day 28 after birth or upon discharge from the hospital.
There is an increasing incidence of Necrotizing Enterocolitis (NEC) affecting the premature infant population, principally those with associated risk like extreme prematurity, extreme low birth weight, associated co-morbidities (Congenital heart disease, perinatal asphyxia) and those born in hospitals with limited resources for optimal neonatal care. Near Infrared Spectroscopy (NIRS), has been used in premature infants to evaluate changes in cerebral perfusion and oxygenation. (1) It provides real time insight into the oxygen delivery.(3) In the premature patient population, many neurologic injuries occur as a result of prenatal (pre-existing) and/or postnatal disturbance on oxygen delivery. NIRS has been focused in cerebral monitoring. Light easily penetrates through neonatal bone and skin tissue, and allows to monitor the subjacent oxygen content. Early studies were performed to validate NIRS measurements and have established normative data.(4-6) The non-invasive method of monitoring cerebral hemodynamics and oxygenation has revolutionized the intensive care units in patients at risk for neurological injuries. This method has been successfully validated to monitor neonatal cerebral oxygenation in different clinical settings and study protocols. (7) NIRS provides non-invasive, continuous information on tissue perfusion and oxygen dynamics. One of the biggest challenges of NEC spectrum diseases is in the making of early diagnosis. It is important to monitor not just cerebral perfusion but also the intestinal oxygenation.(8,9) Previous studies with NIRS have demonstrated that premature infants change their cerebral - splanchnic oxygenation ratios during feedings.(10) Guy et al. performed NIRS in premature piglets to demonstrate association of perfusion change with NEC spectrum(11,12); these studies suggest evidence that NIRS could be a useful diagnostic tool in the premature infant population trough abdominal NIRS (a-NIRS) measurement capable of detecting alterations in intestinal oxygenation and perfusion. In summary, a-NIRS could be use in the premature infant population to define reference values, especially in patients at risk, which would then facilitate the early diagnosis of NEC spectrum diseases.
Study, the inclusion of very low birth weight premature infants followed in Dr.Sami Ulus Maternity and Children Training and Research Hospital, Department of Neonatology; be randomized to very low birth weight premature infants began eating until you are discharged from the hospital once a day to feed a group+ 900 mg of 5 billion active Bifidobacterium lactis, the addition of chicory inulin, in the other group given placebo; Patients taking weekly blood cultures, the presence of residues in both groups during feeding, to evaluate the incidence of NEC and sepsis are planned. Randomization and the number of patients planned to separate into groups.
During the first four days of life, intestinal fatty acid binding protein (iFABP) is elevated in the urine of premature babies who go on to develop necrotizing enterocolitis (NEC) days to weeks later. This study aims to determine whether the withholding of feedings in babies with an elevated urinary iFABP can reduce the incidence of NEC.
Necrotizing enterocolitis (NEC) is one of the most devastating gastrointestinal emergencies in preterm neonates and a leading cause of death and morbidity. The pathogenesis of NEC remains largely unclear, but it is widely considered as a multifactorial disease. Prematurity, enteral feeding, bacterial colonisation of the gut and intestinal ischemia have been proposed as major risk factors. Probiotics may prevent NEC by improving the maturity and function of the gut mucosal barrier, modulating the immune system, promoting colonization of the gut with beneficial organisms and preventing colonization by pathogens. A variety of clinical trials have evaluated the effect of different probiotic preparations on the occurrence of NEC in preterm infants. The results of recent metaanalyses suggest a benefit of probiotic bacteria in reducing the incidence of NEC and propose a change of practice. The aim of the study is to evaluate the efficacy of the probiotic preparation Infloran® in reducing the incidence of NEC after implementation in clinical routine in preterm (< 34 weeks gestational age) very low birth weight infants compared to a historical cohort.
- The purpose of this study is to determine whether docosahexaenoic acid is effective in the prevention or reducing severity of necrotizing enterocolitis (NEC) in preterm neonates < 1500 g at birth who are starting enteral feeding. - if NEC is prevented, this study will measure whether hospital stay is also reduced in neonates who receive Docosahexaenoic acid (DHA)
Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency encountered in the newborn intensive care unit and represents a significant cause of morbidity and mortality in infants born prematurely. Among possible risk factors, a strong association between elective RBC transfusions in premature infants with anemia and the subsequent development of NEC has been consistently observed (6-11). However, a significant (and increasing) number of VLBW infants with anemia are managed with erythropoiesis stimulating agents (such as Epo) and iron and do not receive RBC transfusions during their hospital stay. The present study proposes to study this particular group of VLBW infants that remain with low (<28 %) hematocrit while receiving full enteral feedings. The investigators hypothesize that significant anemia in VLBW infants will be associated with a baseline low cerebro-splanchnic oxygenation ratio (CSOR) (<0.75) as measured by NIRS, and that nasogastric feedings (NGF) in those particular patients will lead to further decreased splanchnic oxygenation. The investigators further postulate that CSOR values will be significantly lower among VLBW that develop NEC as compared to infants that do not.
Despite many advances in neonatal care, necrotizing enterocolitis (NEC) remains a leading cause of morbidity and mortality among premature infants. NEC is the most common life-threatening gastrointestinal emergency encountered in the neonatal intensive care unit, affecting between 3.8% and 13% of very low birthweight (VLBW) infants (1-3). More recently interest has intensified regarding the possible association between "elective" red blood cell (RBC) transfusions in premature infants and the subsequent development of NEC (4-9). On a physiological basis, a few explanations for transfusion-associated NEC have been proposed: 1) the physiological impact of anemia that can initiate a cascade of events leading to ischemic-hypoxemic mucosal gut injury predisposing to NEC [10]; and 2) increased splanchnic blood flow following RBC transfusion leading to reperfusion injury of gut mucosa. Aim 1. This study will quantify inflammatory cytokine profiles in anemic infants cared for in the NICU prior to and after transfusion with packed red blood cells (PRBC), as dictated by current clinical guidelines for treatment of anemia, and prospectively assess for clinical signs and symptoms of NEC following each transfusion event. Aim 2. Polymorphonuclear leukocytes (PMNs) isolated from the pre- and post-transfusion blood samples will be assessed in vitro for neutrophil extracellular traps (NET) formation. Aim 3. A) To determine whether significant anemia preceding a RBC transfusion is associated with impaired intestinal oxygenation, and whether a RBC transfusion temporarily increases splanchnic oxygenation. We postulate that the CSOR will be low (<0.75) at baseline measurement in infants with hemodynamically significant anemia, and that RBC transfusion will temporarily increase intestinal perfusion in that particular group of babies. B) To determine whether alterations in mesenteric regional oxygenation saturation(rSO2) can predict the development of NEC in VLBW infants. We hypothesize that overall cerebro-splanchnic oxygenation ratio (CSOR) values will be significantly lower among very low birth weight (VLBW) infants that develop NEC, when compared to CSOR values obtained in infants that do not develop NEC following RBC transfusion.
The purpose of this study is to compare the additional use of gloves (with handwashing before and after gloving) for all patient contact while infants have intravenous (central or peripheral) access in a RCT. Preterm infants <1000 grams or less than 29 weeks gestational age will be randomized after birth to either a handwashing-gloving group or handwashing only group. The primary outcome will be the incidence of invasive infections (bacterial or fungal) or necrotizing enterocolitis. Secondary outcomes will include hospital days, preterm morbidities, mortality, and hospital costs.
Survival of preterm infants has increased greatly over the years, so a major aim now is to improve the long term outlook for these babies and to avoid serious complications. The way babies are fed in early life affects short and long-term health and survival. Because the bowels of preterm infants have not matured, they cannot digest large volumes of milk feeds straight away. Until the gut matures, nutrition is provided by intravenous drip while the amount of milk given is gradually increased over time. Increasing the amount of milk rapidly may increase the risk of gut complications. Increasing the amount of milk given more slowly means that intravenous nutrition is needed for longer; there is an associated risk of infection proportional to the time the intravenous line is present in the bloodstream of these infants. Despite the importance of milk feeding preterm infants, there have been few studies to inform how best to balance these risks, and what the best way to increase feeds in these infants is - this study sets out to address this missing information. The study will compare two different speeds of milk feed increase, one 'faster' and one 'slower', both within rates currently used in United Kingdom neonatal units. The study aims to find out if either speed of milk feed increase gives better outcomes for the infants. Investigators will measure a variety of outcomes, such as survival without disability, infection, bowel problems, growth and long-term physical and mental development, as well as the impact on families and the National Health Service, including costs. The study is being led by an established team of researchers who have run similar studies before, and uses an established network of neonatal units that have taken part in previous studies.
