Filter by:The overall primary objective is to establish the feasibility and pilot the design and delivery of a diagnostic randomized controlled trial (RCT) of BUS (bowel ultrasound) for NEC evaluation which will lead to a successful application for a larger, multi-center clinical trial in the future. This program of research is anticipated to have a significant positive impact in the timely and accurate diagnosis of NEC in preterm infants.
The aim was to assess the ability of bovine colostrum concentrate to reduce the incidence of late-onset sepsis episodes and necrotizing enterocolitis in artificially fed preterm neonates and its effect on T regulatory cells. And to evaluate the effect of bovine colostrum concentrate on feeding tolerance, growth, hospital stay and mortality in preterm neonates.
This study evaluates the effect of repeated low-dose erythropoietin (EPO) treatment on necrotizing enterocolitis (NEC) in very preterm infants. Half of participants will receive EPO, while the other half will receive a placebo.
Necrotizing enterocolitis is the most common gastroenterological emergency in neonatology. Its mortality is high, ranging from 15 to 30%. Prematurity is the main risk factor for necrotizing enterocolitis, as well as the very low birth weight (<1500 g) associated with prematurity. Among the early neonatal complications of intrauterine growth restriction neonates, necrotizing enterocolitis is frequently reported in the literature. The situation of chronic hypoxia of these fetuses is at the origin of a vascular redistribution favoring the cerebral circulation to the detriment of the mesenteric vascularization, which could lead to the development of an necrotizing enterocolitis. However, data from the literature concerning this over-risk of necrotizing enterocolitis in the case of intrauterine growth restriction are discordant. The heterogeneity of the definitions used for the intrauterine growth restriction and diagnostic criteria for necrotizing enterocolitis from one study to another could explain these discrepancies. The investigator's hypothesis is that the risk of necrotizing enterocolitis is higher among newborns in intrauterine growth restriction compared to control children.
Necrotizing enterocolitis (NEC) affects up to 10% of very preterm infants. NEC mortality is high (30-50 %) and has remained unchanged over the last decades. New treatments are urgently needed. NEC pathogenesis is multifactorial, but bowel ischemia plays an essential role in NEC development. Remote ischemic conditioning (RIC) consists in inducing brief periods of non-lethal ischemia in a limb distant to an organ suffering from ischemia. RIC has been used in adults, children and term neonates with a variety of diagnosis. However, no study has been done including preterm infants with NEC.
Very preterm infants (<32 weeks gestation) show the immaturity of organs and have high nutrient requirements for growth and development. In the first weeks, they have difficulties tolerating enteral nutrition (EN) and are often given supplemental parenteral nutrition (PN). A fast transition to full EN is important to improve gut maturation and reduce the high risk of late-onset sepsis (LOS), related to their immature immunity in gut and blood. Conversely, too fast increase of EN predisposes to feeding intolerance and necrotizing enterocolitis (NEC). Further, human milk feeding is not sufficient to support nutrient requirements for growth of very preterm infants. Thus, it remains a difficult task to optimize EN transition, achieve adequate nutrient intake and growth, and minimize NEC and LOS in the postnatal period of very preterm infants. Mother´s own milk (MM) is considered the best source of EN for very preterm infants and pasteurized human donor milk (DM) is the second choice if MM is absent or not sufficient. The recommended protein intake is 4-4.5 g/kg/d for very low birth infants when the target is a postnatal growth similar to intrauterine growth rates. This amount of protein cannot be met by feeding only MM or DM. Thus, it is common practice to enrich human milk with human milk fortifiers (HMFs, based on ingredients used in infant formulas) to increase growth, bone mineralization and neurodevelopment, starting from 7-14 d after birth and 80-160 ml/kg feeding volume per day. Bovine colostrum (BC) is the first milk from cows after parturition and is rich in protein (80-150 g/L) and bioactive components. These components may improve gut maturation, NEC protection, and nutrient assimilation, even across species. Studies in preterm pigs show that feeding BC alone, or DM fortified with BC, improves growth, gut maturation, and NEC resistance during the first 1-2 weeks, relative to DM, or DM fortified with conventional HMFs. On this background, the investigators hypothesize that BC, used as a fortifier for MM or DM, can reduce feeding intolerance than conventional fortifiers.
This is a randomised controlled multi-centre trial comparing the effect of diet supplementation of a human breast milk-based nutrient fortifier (H2MF®) with standard bovine protein-based nutrient fortifier in 222 extremely preterm infants (born before gestational week 28+0) exclusively fed with human breast milk (own mother´s milk and/or donor milk). The infants will be randomised to receive either the human breast-milk based H2MF® or the standard bovine protein-based nutrient fortifier when oral feeds have reached <100 ml/kg/day. The randomised intervention, stratified by centre, will continue until the target gestational week 34+0. The infant must not be fed with formula during the intervention period. The allocation will be concealed before inclusion, but after randomisation the study is not blinded. Primary endpoint of the intervention is the composite variable necrotizing enterocolitis (NEC), sepsis and mortality. The enrolled infants are characterised with clinical data including growth, feeding intolerance, use of enteral and parenteral nutrition, treatment, antibiotics and complications collected daily in a study specific case report form from birth until discharge from the hospital (not longer than gestational week 44+0). A follow up focusing on neurological development, growth and feeding problems will be performed at 2 years of age (corrected) and 5.5 years of age.
BACKGROUND: Human milk (HM) is recommended for all very low birth infants (VLBW)). Breast-milk is highly variable in nutrient content, failing to meet the nutritional demands of VLBW. Fortification of HM is recommended to prevent extra-uterine growth retardation and associated poor neurodevelopmental outcome. However, standard fortification with fixed dose multicomponent fortifier does not account for the variability in milk composition. Targeted fortification is a promising alternative and needs further investigation. The aim of the study is to evaluate if targeted fortification of human milk may optimize growth and development in preterm infants. STUDY DESIGN: Randomized single blind controlled trial. METHODS & ANALYSIS: We will recruit preterm infants (≤ 32 weeks of gestation) within the first 7 days of life. After reaching 80 ml/kg/day of enteral feeding, patients will be randomised to receive standard fortification (HMF, Nutricia) or targeted fortification (modular components: Bebilon Bialko, Nutricia - protein, Fantomalt, Nutricia - carbohydrates, Calogen, Nutricia - lipids). The intervention will continue until 37 weeks of post-conception age, or hospital discharge. Parents and outcome assessors will be blinded to the intervention. The primary outcome - weight gain velocity will be measured starting from the day infants regain their birth weight up to 4 weeks, then weekly until discharge. Secondary outcomes such as neurodevelopment at 12 months of corrected age (CA) will be assessed with Bayley Scale of Development III, repeated at 36 months of CA. Additionally a Wescheler Preschool and Primary Scale of Intelligence IV test will be applied at 3,5 years of CA. Secondary outcomes such as length and head growth, body composition will be assesed at discharge and at 4 months. Incidence of necrotizing enterocolitis (NEC), sepsis, retinopathy of prematurity (ROP) and bronchopulmonary dysplasia (BPD) will also be followed.
Premature infants are at risk for a variety of diseases, the investigators would like to learn more about why some premature babies are at higher risk and some are protected from these diseases. Scientists at UC Davis and other universities have developed new ways to measure the bacteria and a large number of small molecules in specimens of infant blood, urine, stomach fluid and poop and in mother's milk. These discoveries allow us to consider questions that were impossible to answer before these new techniques were developed. One such question is whether the bacteria in the poop of a premature baby can help us predict the baby's risk for developing infection or a common and serious disease of premature infants called necrotizing enterocolitis. A second question is whether the DNA of a premature baby (obtained from saliva with a q-tip) can predict higher risk for diseases of premature babies.
The study will assess the efficacy of Docosahexaenoic Acid in reducing the incidence of necrotizing enterocolitis in premature infants.
