NCT ID: NCT01745510 Completed - Clinical trials for Necrotizing Enterocolitis

Enteral Administration of Docosahexaenoic Acid to Prevent Necrotizing Enterocolitis in Preterm Neonates

Start date: October 2012
Phase: Phase 1/Phase 2
Study type: Interventional

- 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)

NCT ID: NCT01735578 Completed - Clinical trials for Necrotizing Enterocolitis

Splanchnic Tissue Oxygenation During Enteral Feedings in Anemic Premature Infants at Risk for Necrotizing Enterocolitis

Start date: October 2012
Phase: N/A
Study type: Observational

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.

NCT ID: NCT01735552 Terminated - Clinical trials for Necrotizing Enterocolitis

Transfusion-related Inflammatory Cytokine and Neutrophil Extracellular Trap Quantification in Neonates

Start date: June 2012
Phase: N/A
Study type: Observational

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.

NCT ID: NCT01729000 Completed - Neonatal Infection Clinical Trials

Study to Determine if Gloving in Addition to Hand Hygiene Will Prevent Invasive Infections and Necrotizing Enterocolitis

Start date: October 2008
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01727609 Completed - Premature Birth Clinical Trials

Speed of Increasing Milk Feeds Trial

SIFT
Start date: June 2013
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01699516 Recruiting - Clinical trials for Neutropenic Enterocolitis

Non-invasive Contrast Enhanced Ultrasound Sonography in Intestinal Acute Graft-vs-Host Disease

Start date: January 2008
Phase: N/A
Study type: Observational

Intestinal acute graft-vs-host disease (GVHD) is a life-threatening complication after allogeneic hematopoietic cell transplantation. Non-invasive diagnostic procedures are still lacking and diagnosis is difficult. We hypothesized that contrast-enhanced ultrasound sonography (CEUS) could detect microcirculation changes of the bowel walls during intestinal GVHD and help to detect and monitor treatment response. We employed CEUS to prospectively evaluate intestinal GVHD in 83 consecutive transplant patients between 2008 and 2011. Fourteen /83 patients with biopsy-proven intestinal GVHD were selected as study group. Fourteen patients with biopsy-proven stomach GVHD without intestinal symptoms (N=16), normal volunteers (N=6) and patients with neutropenic enterocolitis (N=4), were chosen as control group. All patients were evaluated with both standard transabdominal ultrasonography (US) and CEUS at the onset of intestinal symptoms, during clinical follow up and at flare of symptoms. Standard US revealed non-specific bowel wall thickening, and simultaneous involvement of multiple intestinal segments in 9/14 patients. CEUS showed three distinct patterns of microcirculation changes that correlated with GVHD activity. These findings were not observed in the control group. Moreover, CEUS findings correlated with treatment response and predicted flare of intestinal symptoms. CEUS is a non-invasive, easily reproducible bed-side tool to detect and monitor intestinal GVHD.

NCT ID: NCT01674478 Completed - Prematurity Clinical Trials

Early Supplementation of Enteral Microlipid With and Without Fish Oil in Premature Infants With Enterostomies

EMLFO-2
Start date: October 2012
Phase: Phase 2
Study type: Interventional

Necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) are common devastating gastrointestinal diseases in premature infants. These infants often need surgical intervention to remove the dead bowel and create temporary enterostomies, resulting in short bowel syndrome (SBS), a malabsorption state due to insufficient bowel length or dysfunction to digest and absorb nutrients adequately. These infants are often nourished primarily with parental nutrition (PN) which can lead to many complications including PN-associated liver disease. However, with enteral feeding, the remaining bowel can adapt somewhat to the shortened state, reducing the need for PN. Enteral fats appear to be the most trophic macronutrients with the long chain polyunsaturated fatty acids (LCPUFA) being the most beneficial in promoting bowel adaptation. Fish oil (FO), a main source of n-3 LCPUFA, has been shown to promote bowel adaptation. Microlipid (ML) primarily contains n-6 PUFA and has been found to decrease ostomy output and increase weight gain in some SBS infants. WThe investigators will soon have completed a randomized clinical trial (EMLFO trial) (WFUHS IRB00011501, NCT01306838) entitled "Early Supplementation of Enteral Lipid with Combination of Microlipid and Fish Oil in Infants with Enterostomies". The preliminary data suggest that (a) by supplementing enteral ML/FO, we were able to decrease the use of IL; (b) premature infants in the treatment group who received ML/FO achieved higher enteral calorie (% of total calorie) intake before reanastomosis and better weight gain (g/day) after reanastomosis than those who received routine care in control group; and (c) the direct bilirubin level before reanastomosis tended to be lower in the treatment group than the control group although the difference was not statistically significant. Because the intervention consisted of both an increase in enteral fat intake as well as a specific type of fat intake (i.e. FO), it is unclear whether improved outcomes in the ML/FO group are attributable to FO's anti-inflammatory effects or the increased fat intake. Therefore, the investigators have designed a next randomized clinical trial to compare ML alone versus ML plus FO. We hypothesize that as compared to ML alone, ML plus FO will result in decreased systemic inflammation, as indicated by blood levels of inflammation-related proteins and indicators of oxidative stress.

NCT ID: NCT01670916 Completed - Clinical trials for Necrotizing Enterocolitis

Probiotics to Prevent NEC - a Historical Control Study

Start date: March 2010
Phase: Phase 4
Study type: Observational

Probiotics is given routinely to infants admitted to the department of neonatology during the first 3 days of life with gestational age less than 30 weeks since March 2010. The incidence of necrotizing enterocolitis Bell stage II and III will be assessed blindly from clinical records. It is hypothesised that the incidence of NEC will decrease. Infants admitted from 1 March 2010 to 28 February 2013 will be compared to infants admitted 1 Dec 2007 to 30 Nov 2009 will be compared.

NCT ID: NCT01603368 Completed - Sepsis Clinical Trials

Prophylactic Probiotics to Extremely Low Birth Weight Prematures

PROPEL
Start date: June 2012
Phase: Phase 2
Study type: Interventional

Mortality and incidence of severe complications is still high among extremely premature infants. Common causes of severe complications in this population are poor nutrition, necrotizing enterocolitis, and severe infections. Feeding intolerance is also a common problem resulting in prolonged need for intravenous lines and poor nutrition. The aim of the study is to evaluate whether supplementation with the probiotic bacterium Lactobacillus reuteri DSM 17938 daily to premature infants with extremely low birth weight increases feeding tolerance to breast milk and thereby improves nutrition, increases growth and reduces serious complications and mortality in this population. Beyond this, possible mechanisms underlying these effects will be analyzed in stool, breast milk and blood samples.

NCT ID: NCT01531179 Completed - Clinical trials for Necrotizing Enterocolitis

Lactobacillus Reuteri for Prevention of Necrotizing Enterocolitis in Very Low-birth Weight Infants

Start date: February 2012
Phase: Phase 3
Study type: Interventional

Probiotics are favorable microorganisms that regulate the flora of the gastrointestinal system and stimulate the immune system. Necrotizing enterocolitis incidence is 10-25% in newborn infants whose birth weights are < 1500 g. Although bifidobacterium and other lactobacilli spp. have been used to reduce the incidence of necrotizing enterocolitis in clinical trials, Lactobacillus reuteri has not been used in the prevention of necrotizing enterocolitis in very low birth weight infants yet. The objective of this study is to evaluate the efficacy of orally administered Lactobacillus reuteri in reducing the incidence and severity of necrotizing enterocolitis in very low birth weight infants.
