Yang X, Liu G, Yi B. Mdr3 gene mutation in preterm infants with parenteral nutrition-associated cholestasis. Mol Genet Genomic Med 2022; 10:e1875. [PMID: 35150476 PMCID: PMC8922965 DOI: 10.1002/mgg3.1875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 12/31/2021] [Accepted: 01/06/2022] [Indexed: 11/11/2022] Open
Abstract
To investigate the relationship of multidrug resistance 3 (Mdr3) gene mutation and parenteral nutrition‐associated cholestasis (PNAC) in preterm infants. Preterm infants who had received total parenteral nutrition for at least 14 days were enrolled: 76 preterm infants in the PNAC group and 80 preterm infants in the non‐PNAC group. Genomic DNA was extracted from white blood cells. Twenty‐eight exons of the Mdr3 gene were amplified by polymerase chain reaction. PNAC infants of 1 month corrected age with the Mdr3 gene mutation and abnormal liver biochemistry were selected for the experimental liver biopsy group. Five normal adult living liver transplantation donors were enrolled in a normal donor group. The Mdr3 missense mutations c.1031G>A, c.3347G>A, and c.485T>A, and the Mdr3 frameshift mutation c.2793_2794insA were found in the PNAC group. The allele frequency and genotype frequency of c.1031G>A, c.3347G>A, and c.485T>A in the Mdr3 gene in the PNAC group were significantly higher than those in non‐PNAC group (p < 0.05). The rate of Mdr3 gene mutations c.1031G>A, c.485T>A, c.3347G>A, and c.2793_2794insA in the PNAC group was higher than in the non‐PNAC group (21.05% vs. 1.25%, respectively, χ2 = 15.747, p < 0.05). Mdr3 gene mutations c.2793_2794insA, c.1031G>A, c.3347G>A, and c.485T>A may be the genetic cause of PNAC.

NF-κB Regulation of LRH-1 and ABCG5/8 Potentiates Phytosterol Role in the Pathogenesis of Parenteral Nutrition-Associated Cholestasis. Hepatology 2021; 74:3284-3300. [PMID: 34310734 PMCID: PMC8639620 DOI: 10.1002/hep.32071] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 06/30/2021] [Accepted: 07/13/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS Chronically administered parenteral nutrition (PN) in patients with intestinal failure carries the risk for developing PN-associated cholestasis (PNAC). We have demonstrated that farnesoid X receptor (FXR) and liver X receptor (LXR), proinflammatory interleukin-1 beta (IL-1β), and infused phytosterols are important in murine PNAC pathogenesis. In this study we examined the role of nuclear receptor liver receptor homolog 1 (LRH-1) and phytosterols in PNAC. APPROACH AND RESULTS In a C57BL/6 PNAC mouse model (dextran sulfate sodium [DSS] pretreatment followed by 14 days of PN; DSS-PN), hepatic nuclear receptor subfamily 5, group A, member 2/LRH-1 mRNA, LRH-1 protein expression, and binding of LRH-1 at the Abcg5/8 and Cyp7a1 promoter was reduced. Interleukin-1 receptor-deficient mice (Il-1r-/- /DSS-PN) were protected from PNAC and had significantly increased hepatic mRNA and protein expression of LRH-1. NF-κB activation and binding to the LRH-1 promoter were increased in DSS-PN PNAC mice and normalized in Il-1r-/- /DSS-PN mice. Knockdown of NF-κB in IL-1β-exposed HepG2 cells increased expression of LRH-1 and ABCG5. Treatment of HepG2 cells and primary mouse hepatocytes with an LRH-1 inverse agonist, ML179, significantly reduced mRNA expression of FXR targets ATP binding cassette subfamily C member 2/multidrug resistance associated protein 2 (ABCC2/MRP2), nuclear receptor subfamily 0, groupB, member 2/small heterodimer partner (NR0B2/SHP), and ATP binding cassette subfamily B member 11/bile salt export pump (ABCB11/BSEP). Co-incubation with phytosterols further reduced expression of these genes. Similar results were obtained by suppressing the LRH-1 targets ABCG5/8 by treatment with small interfering RNA, IL-1β, or LXR antagonist GSK2033. Liquid chromatography-mass spectrometry and chromatin immunoprecipitation experiments in HepG2 cells showed that ATP binding cassette subfamily G member 5/8 (ABCG5/8) suppression by GSK2033 increased the accumulation of phytosterols and reduced binding of FXR to the SHP promoter. Finally, treatment with LRH-1 agonist, dilauroyl phosphatidylcholine (DLPC) protected DSS-PN mice from PNAC. CONCLUSIONS This study suggests that NF-κB regulation of LRH-1 and downstream genes may affect phytosterol-mediated antagonism of FXR signaling in the pathogenesis of PNAC. LRH-1 could be a potential therapeutic target for PNAC.

Abstract
The role of macrolides for the prevention and treatment of feeding intolerance (FI) in preterm low birth weight (LBW) infants has not been well established. To assess the efficacy and safety of macrolides to prevent or treat FI in preterm LBW infants. A systematic review and meta-analysis (PROSPERO ID: CRD42020170519) was conducted for English articles published since inception to March 2020, using MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. Search terms included preterm low birth weight infants, macrolides, erythromycin, azithromycin, clarithromycin, and feeding intolerance. Randomized controlled trials (RCTs) assessing the effects of macrolide therapy on the time to achieve full enteral feeding (FEF;150 mL/kg/day), duration of parenteral nutrition (PN), hospitalization, and adverse events in preterm LBW infants were included. Independent extraction of data was done by both authors using predefined data-sheet. Very-low to low-quality evidence from 21 RCTs, 19 for erythromycin (prophylaxis-6, rescue-13) and 2 for clarithromycin (prophylaxis-1, rescue-1) demonstrated a significantly beneficial role of erythromycin for an earlier FEF, both as a prophylaxis (SMD-0.53, 95% CI - 0.74,- 0.33; 6 studies, n = 368) as well as rescue (SMD-1.16, 95% CI - 1.88, - 0.44; 11 studies, n = 664). Rescue therapy was also beneficial for a significant reduction in the duration of PN, hospitalization, incidences of sepsis, necrotizing enterocolitis, and cholestasis. No arrhythmia or infantile hypertrophic pyloric stenosis was reported.Conclusions: Erythromycin therapy, both as prophylaxis and rescue, is beneficial to reduce the time to achieve FEF in preterm LBW infants, at no higher risk of adverse events.Trial registration: PROSPERO ID: CRD42020170519.

Abstract
BACKGROUND To assess the appropriate energy expenditure requirement for liver transplant (LT) recipients in South Korea, 4 commonly used predictive equations were compared with indirect calorimetry (IC). METHODS A prospective observational study was conducted in the surgical intensive care unit (ICU) of an academic tertiary hospital between December 2017 and September 2018. The study population comprised LT recipients expected to remain in the ICU >48 hours postoperatively. Resting energy expenditure (REE) was measured 48 hours after ICU admission using open-circuit IC. Theoretical REE was estimated using 4 predictive equations (simple weight-based equation [25 kcal/kg/day], Harris-Benedict, Ireton-Jones [ventilated], and Penn State 1988). Derived and measured REE values were compared using an intraclass correlation coefficient (ICC) and Bland-Altman plots. RESULTS Of 50 patients screened, 46 were enrolled, were measured, and completed the study. The Penn State equation showed 65.0% agreement with IC (ICC, 0.65); the simple weight-based (25 kcal/kg/day), Harris-Benedict, and Ireton-Jones equations showed 62.0%, 56.0% and 39.0% agreement, respectively. Bland-Altman analysis showed that all 4 predictive equations had fixed bias, although the simple weight-based equation (25 kcal/kg/day) showed the least. CONCLUSION Although predicted REE calculated using the Penn State method agreed with the measured REE, all 4 equations showed fixed bias and appeared to be inaccurate for predicting REE in LT recipients. Precise measurement using IC may be necessary when treating LT recipients to avoid underestimating or overestimating their metabolic needs.

Abstract
BACKGROUND Cholestasis is a serious complication of total parenteral nutrition (TPN) in neonates. Liver biopsies may be requested to assess the severity of cholestasis and fibrosis. We hypothesized that liver biopsy would not lead to changes in management or improved patient outcomes. METHODS A single institution retrospective review of infants with TPN cholestasis from January 2008 to January 2016. OUTCOMES length of stay, complications, change in management and mortality. Statistical analysis was performed using Fisher's exact test. RESULTS Twenty-seven out of 95 patients with TPN cholestasis underwent liver biopsy. Liver biopsy was associated with increased utilization or ursodeoxycholic acid (p = 0.001). There were no differences in length of stay (LOS) or mortality. One patient had a complication following anesthesia for liver biopsy, there were no bleeding complications recorded. CONCLUSIONS Liver biopsy in patients with TPN cholestasis was associated with an increase in utilization of ursodeoxycholic acid. The effects of this are not fully understood; however, liver biopsy was not associated with improved patient outcomes such as LOS or mortality.

Abstract
Intestinal failure (IF)-associated liver disease (IFALD) is widely recognized as a lethal complication of long-term parenteral nutrition. The pathophysiology of IFALD is poorly understood but appears to be multifactorial and related to the inflammatory state in the patient with IF. Visceral transplant for IFALD includes variants of intestine, liver, or combined liver-intestine allografts. Graft selection for an individual patient depends on the etiology of IF, abdominal and vascular anatomy, severity of IFALD, and potential for intestinal rehabilitation. The past decade has witnessed dramatic improvement in the management of IFALD, principally due to improved lipid emulsion formulations and the multidisciplinary care of the patient with IF. As the recognition and treatment of IFALD continue to improve, the requirement of liver-inclusive visceral grafts appears to be decreasing, representing a paradigm shift in the care of the patient with IF. This review highlights the current indications, graft selection, and outcomes of visceral transplantation for IFALD.

Abstract
In infants intolerant of enteral feeding because of intestinal disease, parenteral nutrition may be associated with cholestasis, which can progress to end-stage liver disease. Here we show the function of hepatic macrophages and phytosterols in parenteral nutrition-associated cholestasis (PNAC) pathogenesis using a mouse model that recapitulates the human pathophysiology and combines intestinal injury with parenteral nutrition. We combine genetic, molecular, and pharmacological approaches to identify an essential function of hepatic macrophages and IL-1β in PNAC. Pharmacological antagonism of IL-1 signaling or genetic deficiency in CCR2, caspase-1 and caspase-11, or IL-1 receptor (which binds both IL-1α and IL-1β) prevents PNAC in mice. IL-1β increases hepatocyte NF-κB signaling, which interferes with farnesoid X receptor and liver X receptor bonding to respective promoters of canalicular bile and sterol transporter genes (Abcc2, Abcb11, and Abcg5/8), resulting in transcriptional suppression and subsequent cholestasis. Thus, hepatic macrophages, IL-1β, or NF-κB may be targets for restoring bile and sterol transport to treat PNAC.

Abstract
Intestinal transplantation is an accepted lifesaving option to treat appropriately selected patients with end-stage failure of the gastrointestinal tract. The evaluation of each candidate involves complex judgments. When to perform an isolated intestinal transplantation versus a combined transplantation with the liver and/or other organs often requires thoughtful considerations and an individualized approach. In addition, performing venous drainage of the isolated graft is potentially complex. We discuss the significant advances in surgical and medical decision making in the evaluation and management of patients with intestinal failure.

Abstract
Medium chain fatty acids (MCFA) can be more easily absorbed and supply energy more rapidly than long chain fatty acids (LCFA). However, little is known about the inflammatory response by the treatment of MCFA in human liver cells. Thus this study used human liver cells (LO2) to evaluate the effects of MCFA on apoptosis and inflammatory response. Tetrazolim-based colorimetric assay and lactate dehydrogenase assay were used to measure the viability of LO2 cells, isolated spleens and liver cells from BALB/C mice. Inverted fluorescence microscopy and flow cytometry were used to assess the cell apoptosis. Activity of superoxide dismutase and malondialdehyde level were measured to determine the oxidative damage. mRNA or protein levels of classical pro-inflammatory cytokines were analyzed by quantitative real-time polymerase chain reaction (qPCR), enzyme-linked immunosorbent assay and western blotting. The results showed that the liver cells treated with the fatty acids at 200 μM for 24 h exhibited good viability. Fatty acids induced inflammatory cytokines at transcriptional and translational levels to a lesser extent than lipopolysaccharide. LCFA (oleic acid) up-regulated tumor necrosis fator-α, monocyte chemoattractant-1 and interleukin-1β while down-regulated IL-6 and IL-8 secretion to a higher extent than MCFA in mRNA and protein levels. These findings suggested that MCFA may induce apoptosis to a less extent and exert more gentle inflammation than LCFA in human liver cells.

Abstract
The aim of this study was to investigate mutations of multidrug resistance 3 (MDR3) exons 9 and 23 in infants with parenteral nutrition-associated cholestasis (PNAC). A total of 41 infants with PNAC were enrolled in the study. Genomic DNA was extracted from the peripheral venous blood leukocytes of each patient and MDR3 exons 9 and 23 were amplified by polymerase chain reaction. One patient was identified who carried a frameshift mutation in MDR3 exon 23 (C.2793) that was caused by the insertion of a single adenine residue, while mutations were not found in MDR3 exon 23 in the other 40 patients. The clinical features of the patient with the MDR3 exon 23 frameshift mutation included high serum γ-glutamyl transferase levels, the absence of biliary dilatation and deformity in magnetic resonance cholangiopancreatography, and abnormal electrical capacitance tomography imaging of the liver. No mutations in MDR3 exon 9 were identified in any of the patients. All 41 PNAC patients recovered following oral ursodeoxycholic acid treatment. The C.2793 frameshift mutation in MDR3 exon 23 is potentially associated with the development of PNAC in infants.

Abstract
BACKGROUND Feeding intolerance is a common clinical problem among preterm infants. It may be an early sign of necrotising enterocolitis, sepsis or other serious gastrointestinal conditions, or it may result from gut immaturity with delayed passage of meconium. Glycerin laxatives stimulate passage of meconium by acting as an osmotic dehydrating agent and increasing osmotic pressure in the gut; they stimulate rectal contraction, potentially reducing the incidence of feeding intolerance. OBJECTIVES To assess the effectiveness and safety of glycerin laxatives (enemas/suppositories) for prevention or treatment of feeding intolerance in very low birth weight (VLBW) infants. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 4), MEDLINE, EMBASE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We restricted our search to all randomised controlled trials and applied no language restrictions. We searched the references of identified studies and reviews on this topic and handsearched for additional articles. We searched the database maintained by the US National Institutes of Health (www.clinicaltrials.gov) and European trial registries to identify ongoing trials. SELECTION CRITERIA We considered only randomised or quasi-randomised controlled trials that enrolled preterm infants < 32 weeks' gestational age (GA) and/or < 1500 g birth weight. We included trials if they administered glycerin laxatives and measured at least one prespecified clinical outcome. DATA COLLECTION AND ANALYSIS We used standard methods of The Cochrane Collaboration and its Neonatal Group to assess methodological quality of trials, to collect data and to perform analyses. MAIN RESULTS We identified three trials that evaluated use of prophylactic glycerin laxatives in preterm infants. We identified no trials that evaluated therapeutic use of glycerin laxatives for feeding intolerance. Our review showed that prophylactic administration of glycerin laxatives did not reduce the time required to achieve full enteral feeds and did not influence secondary outcomes, including duration of hospital stay, mortality and weight at discharge. Prophylactic administration of glycerin laxatives resulted in failure of fewer infants to pass stool over the first 48 hours. Included trials reported no adverse events. AUTHORS' CONCLUSIONS Our review of available evidence for glycerin laxatives does not support the routine use of prophylactic glycerin laxatives in clinical practice. Additional studies are needed to confirm or refute the effectiveness and safety of glycerin laxatives for prevention or treatment of feeding intolerance in VLBW infants.

Abstract
AIM Necrotising enterocolitis (NEC) is associated with high morbidity and mortality. The aim of this study was to identify predictors of intestinal failure (IF), morbidity and mortality following NEC. METHODS We performed a retrospective study of all neonates treated for NEC stage II or greater at a tertiary referral NICU between 2000 and 2009. Demographic data, need for surgery, residual bowel length and rates of bacteraemia, cholestasis, IF and mortality were analysed. RESULTS During the 10-year period, 301 patients were referred with NEC and 152 had surgical intervention. Overall mortality was 32%. Of the 230 infants who survived >42 days, 97 (42%) had IF at 42 days, decreasing to 15% at >90 days. The rate of IF was significantly higher in the surgical group than the medical group (OR 2.04, 95% CI, 1.25-3.35, p < 0.004), but 23% of the medically treated infants with NEC also developed IF. There was a significant relationship between IF and gram-negative bacteraemia, the need for surgery, cholestasis, liver failure and mortality. CONCLUSION Intestinal failure occurred in a significant proportion of infants with NEC. Predictors for IF among infants with NEC were low birthweight, low gestational age, need for surgical intervention and gram-negative bacteraemia.

Abstract
OBJECTIVE To compare the blood flow velocities of superior mesenteric artery (SMA) before versus after clarithromycin treatment for feeding intolerance in very low-birth weight infants. METHODS A prospective study was conducted in a group of infant <1500 g with feeding intolerance who received clarithromycin 7.5 mg/kg/dose bid. Before and at the third day of the clarithromycin therapy, SMA blood flow velocity was measured with Doppler ultrasound. RESULTS SMA peak systolic velocity (PSV) and mean systolic velocity (MV) on the third day of the treatment was found significantly higher than the initial measurement (p = 0.013 and p = 0.027, respectively). End diastolic velocity of the SMA did not change with clarithromycin therapy (p = 0.113). There were no significant changes about pulsatility and resistive index of SMA with regard to clarithromycin therapy. CONCLUSION Clarithromycin effects the splanchnic circulation. The rise in PSV and MV in SMA is remarkable. These results suggest that the splanchnic blood flow increases significantly after clarithromycin usage.

Abstract
Objective. To use a rabbit model of parenteral nutrition-associated liver disease (PNALD) to study changes of the endoplasmic reticulum stress (ERS) marker glucose regulatory protein 94 (GRP94) and determine its role in the pathogenesis of PNALD. Methods. A rabbit PNALD model total parenteral nutrition (TPN) group was established. A corresponding control group received breast-feeding for one week. Serum biochemical parameters were measured and liver histological examinations were performed. The level of GRP94 mRNA and protein were measured. Results. The results showed that the serum TBIL, DBIL, and γ-GT levels in the TPN group were significantly higher than those in the control group, while levels of serum ALB in TPN group were significantly lower than those in the control group. The immunohistochemistry results showed that the protein expression level of GRP94 in the liver of TPN group was significantly increased compared with the control group. The RT-PCR results showed that the level of GRP94 mRNA in the liver of the TPN group was significantly higher compared with the control group. Conclusions. The mRNA and protein levels of GRP94 in the TPN group were both significantly increased, indicating that ERS may be directly related to the occurrence and development of PNALD.

Abstract
Intestinal failure (IF), due to short bowel syndrome (SBS), results from surgical resection of a major portion of the intestine, leading to reduced nutrient absorption and need for parenteral nutrition (PN). The incidence is highest in infants and relates to preterm birth, necrotizing enterocolitis, atresia, gastroschisis, volvulus, and aganglionosis. Patient outcomes have improved, but there is a need to develop new therapies for SBS and to understand intestinal adaptation after different diseases, resection types, and nutritional and pharmacological interventions. Animal studies are needed to carefully evaluate the cellular mechanisms, safety, and translational relevance of new procedures. Distal intestinal resection, without a functioning colon, results in the most severe complications and adaptation may depend on the age at resection (preterm, term, young, adult). Clinically relevant therapies have recently been suggested from studies in preterm and term PN-dependent SBS piglets, with or without a functional colon. Studies in rats and mice have specifically addressed the fundamental physiological processes underlying adaptation at the cellular level, such as regulation of mucosal proliferation, apoptosis, transport, and digestive enzyme expression, and easily allow exogenous or genetic manipulation of growth factors and their receptors (e.g., glucagon-like peptide 2, growth hormone, insulin-like growth factor 1, epidermal growth factor, keratinocyte growth factor). The greater size of rats, and especially young pigs, is an advantage for testing surgical procedures and nutritional interventions (e.g., PN, milk diets, long-/short-chain lipids, pre- and probiotics). Conversely, newborn pigs (preterm or term) and weanling rats provide better insights into the developmental aspects of treatment for SBS in infants owing to their immature intestines. The review shows that a balance among practical, economical, experimental, and ethical constraints will determine the choice of SBS model for each clinical or basic research question.

Abstract
BACKGROUND Parenteral nutrition (PN) has been a life-saving treatment in infants intolerant of enteral feedings. However, PN is associated with liver injury (PN Associated Liver Injury: PNALI) in a significant number of PN-dependent infants. We have previously reported a novel PNALI mouse model in which PN infusion combined with intestinal injury results in liver injury. In this model, lipopolysaccharide activation of toll-like receptor 4 signaling, soy oil-derived plant sterols, and pro-inflammatory activation of Kupffer cells (KCs) played key roles. The objective of this study was to explore changes in the intestinal microbiome associated with PNALI. METHODOLOGY AND PRINCIPAL FINDINGS Microbiome analysis in the PNALI mouse identified specific alterations within colonic microbiota associated with PNALI and further association of these communities with the lipid composition of the PN solution. Intestinal inflammation or soy oil-based PN infusion alone (in the absence of enteral feeds) caused shifts within the gut microbiota. However, the combination resulted in accumulation of a specific taxon, Erysipelotrichaceae (23.8% vs. 1.7% in saline infused controls), in PNALI mice. Moreover, PNALI was markedly attenuated by enteral antibiotic treatment, which also was associated with significant reduction of Erysipelotrichaceae (0.6%) and a Gram-negative constituent, the S24-7 lineage of Bacteroidetes (53.5% in PNALI vs. 0.8%). Importantly, removal of soy oil based-lipid emulsion from the PN solution resulted in significant reduction of Erysipelotrichaceae as well as attenuation of PNALI. Finally, addition of soy-derived plant sterol (stigmasterol) to fish oil-based PN restored Erysipelotrichaceae abundance and PNALI. CONCLUSIONS Soy oil-derived plant sterols and the associated specific bacterial groups in the colonic microbiota are associated with PNALI. Products from these bacteria may directly trigger activation of KCs and promote PNALI. Furthermore, the results indicate that lipid modification of PN solutions may alter specific intestinal bacterial species associated with PNALI, and thus suggest strategies for management of PNALI.

Abstract
The aim of this study was to investigate the association between the mutation of multidrug resistance 3 (MDR3) exon 6 and parenteral nutrition-associated cholestasis (PNAC) in preterm infants. A total of 41 preterm infants with PNAC formed the experimental group, and 56 preterm infants receiving total parenteral nutrition (TPN) for >14 days but without cholestasis formed the control group. Genomic DNA was extracted from peripheral venous blood leukocytes. Polymerase chain reaction was used to amplify exon 6 of the MDR3 gene. The target band of MDR3 gene exon 6 was identified in all blood samples from all cases. We identified five cases with C. 504 C>T heterozygous mutations of exon 6 of the MDR3 gene and 14 cases with C. 504 C>T homozygous mutations in the experimental group. In the control group, we identified seven cases with the C. 504 C>T homozygous mutation and six cases with the C. 504 C>T heterozygous mutation. The distribution of the T/C allele frequency of C. 504 in exon 6 of the MDR3 gene between the experimental group and control group was statistically significant (P<0.05). Further analysis revealed the odds ratio of the T/C allele frequency of the C. 504 mutation in exon 6 of the MDR3 gene between the experimental group and control group to be 0.316. Point mutation C. 485 T>A was detected in one case in the experimental group. The C. 504 C>T and C. 485 T>A MDR3 mutations in exon 6 are possibly responsible for the development of PNAC in infants. C. 504 C>T may not be the only risk factor of neonatal PNAC. In order to further confirm the association between exon 6 of the MDR3 gene and PNAC, a large-sample multicenter study should be carried out.

Abstract
BACKGROUND Elevated plasma phytosterol concentrations are an untoward effect of parenteral nutrition (PN) with vegetable oil-based lipid emulsions (LEs). Phytosterols are elevated in neonatal cholestasis, but the relation remains controversial. OBJECTIVE The objective was to study the effect of 5 LEs on plasma phytosterols in preterm infants. DESIGN One hundred forty-four consecutive admitted preterm infants (birth weight: 500-1249 g) were studied. Patients were randomly assigned to receive 1 of 5 different LEs: S [100% soybean oil (SO)], MS [50% medium-chain triglycerides (MCTs) and 50% SO], MSF (50% MCTs, 40% SO, and 10% fish oil (FO)], OS (80% olive oil and 20% SO), or MOSF (30% MCTs, 25% olive oil, 30% SO, and 15% FO). Phytosterols in the LEs and in plasma (on postnatal day 7 and day 14) were measured by gas chromatography-mass spectrometry. RESULTS Patients in the S group had significantly higher total phytosterol intakes than did the other study groups. On PN days 7 and 14, plasma phytosterol concentrations were highest in the S group and lowest in the MOSF group. Despite similar β-sitosterol intakes between the MS and MSF groups, plasma concentrations were significantly lower in the MSF than in the MS group. Only 3 patients (2.1%) developed cholestasis: 1 in the MS, 1 in the MSF, and 1 in the MOSF group. No cases of cholestasis were observed in the S and OS groups. CONCLUSIONS In uncomplicated preterm infants receiving routine PN, we found a correlation between phytosterol intake and plasma phytosterol concentrations; however, cholestasis was rare and no difference in liver function at 6 wk was observed.

Abstract
OBJECTIVE To compare the effectiveness of oral clarithromycin versus placebo treatment in preventing feeding intolerance in very low birth weight (VLBW) infants. STUDY DESIGN A prospective, randomised controlled trial in which two groups of preterm infants (birth weight <1500 g) were randomised to clarithromycin (7.5 mg/kg/dose every 12 h) or placebo treatment. During the period, 38 infants, whose parents accepted participation, were enrolled in the study. Feeding intolerance and time to achieve full enteral feeding were considered as primary outcome measures. RESULTS Feeding intolerance was significantly longer in placebo than clarithromycin (p = 0.031). Time to achieve full feeding after beginning the treatment was equal among the groups. CONCLUSION This is the first randomised controlled study of clarithromycin and placebo treatment that compares the improvement of feeding intolerance in VLBW infants. Our findings indicate a dramatic improvement in feeding intolerance after oral clarithromycin treatment. But according to our results, clarithromycin-treated infants were not able to attain full enteral feeding more quickly than placebo. This may be due to prophylactic usage of clarithromycin. Significant differences might have resulted if only infants who had feeding intolerance were recruited.

Abstract
Abstract Background: Preterm and growth-restricted babies are at high risk of milk intolerance and necrotising enterocolitis, as well as post-natal growth failure. Objective: To evaluate the effects of an "early" enteral feeding regimen, starting on day 2 after birth compared to late enteral feeding, starting on day 6 after birth in preterm growth restricted babies with abnormal antenatal Doppler studies regarding the incidence of NEC and feeding intolerance. Patients and Methods: Babies with gestational age below 37 weeks, and with birth weight below 10th centile for gestational age, will be randomly allocated to an "early" or "late" enteral feeding regimen. Results: Hundred-thirty three infants enrolled in the study: 66 received early feeding and 67 received delayed feeding. The incidence of NEC and feeding intolerance was not significantly different between the two groups. Conclusion: Early minimal enteral feeding (MEF) of preterm infants with IUGR and abnormal antenatal Doppler results may not have a significant effect on the incidence of NEC or feeding intolerance.

Abstract
BACKGROUND Growth-restricted preterm infants are at increased risk of developing necrotizing enterocolitis (NEC) and initiation of enteral feeding is frequently delayed. There is no evidence that this delay is beneficial and it might further compromise nutrition and growth. METHODS Infants with gestation below 35 weeks, birth weight below the 10th centile, and abnormal antenatal umbilical artery Doppler waveforms were randomly allocated to commence enteral feeds "early," on day 2 after birth, or "late," on day 6. Gradual increase in feeds was guided by a "feeding prescription" with rate of increase the same for both groups. Primary outcomes were time to achieve full enteral feeding sustained for 72 hours and NEC. RESULTS Four hundred four infants were randomly assigned from 54 hospitals in the United Kingdom and Ireland (202 to each group). Median gestation was 31 weeks. Full, sustained, enteral feeding was achieved at an earlier age in the early group: median age was 18 days compared with 21 days (hazard ratio: 1.36 [95% confidence interval: 1.11-1.67]). There was no evidence of a difference in the incidence of NEC: 18% in the early group and 15% in the late group (relative risk: 1.2 [95% confidence interval: 0.77-1.87]). Early feeding resulted in shorter duration of parenteral nutrition and high-dependency care, lower incidence of cholestatic jaundice, and improved SD score for weight at discharge. CONCLUSIONS Early introduction of enteral feeds in growth-restricted preterm infants results in earlier achievement of full enteral feeding and does not appear to increase the risk of NEC.

Abstract
OBJECTIVE To compare the effectiveness of oral erythromycin versus ursodeoxycholic acid (UDCA) treatment in preventing feeding intolerance and liver function abnormalities. STUDY DESIGN A prospective, double blind, randomized, controlled trial in which three groups of preterm infants (birth weight <1500 g) were randomized to erythromycin (12.5 mg kg(-1) per day), UDCA (5 mg kg(-1) every 6 h) or placebo treatment. During the period 352 infants were admitted to our unit of which 75 infants whose parents accepted participation were enrolled in the study. Full enteral feeding or intestinal failure-associated liver disease was considered as the primary outcome measures. RESULTS Time to achieve full feeding after beginning the treatment was significantly shorter in the erythromycin group (P=0.014). γ-Glutamyl transpeptidase levels in the placebo group were significantly higher than in the intervention groups (P=0.001). GTT level was slightly lower in UDCA groups than erythromycin. CONCLUSION Oral erythromycin was most effective in facilitating enteral feeding and UDCA was most effective in preventing cholestasis in very low birth weight infants. Prophylactic usage of UDCA could be considered in infants with prolonged parenteral nutrition.

Abstract
The objective of this study was to determine the impact of parenteral nutrition (PN) on the outcomes of biliary atresia (BA) patients listed for liver transplantation (LT). We retrospectively reviewed the charts of all BA patients at our institution who underwent hepatoportoenterostomy and were listed for LT before the age of 36 months between 1990 and 2010. The initiation of PN was based on clinical indications. Twenty-five PN subjects and 22 non-PN subjects (74% female) were studied. The median PN initiation age was 7.7 months, the mean duration was 86 days, and the mean amount of energy supplied by PN was 77 kcal/kg/day. Before PN, the triceps skinfold thickness (TSF) and the mid-arm circumference (MAC) z scores were decreasing. After PN, TSF (P < 0.001) and MAC (P < 0.001) improved significantly. The PN group had lower MAC and TSF scores than the non-PN group at the time of LT listing. Between listing and LT, MAC and TSF improved in the PN group and worsened in the non-PN groups; as a result, the 2 groups had the same z scores at LT. The PN group had a higher incidence of gastrointestinal bleeding and ascites before LT, but there were no differences in the rates of pre-LT bacteremia, days in the intensive care unit after LT, or patient or graft survival. In conclusion, PN improves the nutritional status of malnourished BA patients awaiting LT, and this is associated with post-LT outcomes comparable to those of patients not requiring PN.

Abstract
OBJECTIVE The aim of this study was to review evidence-based data addressing key clinical questions regarding parenteral nutrition-associated cholestasis (PNAC) and parenteral nutrition-associated liver disease (PNALD) in children. DATA SOURCE Data were obtained from PubMed, Medicine databases of the English literature (up to October 2010), and the Cochrane Database of Systematic Reviews. STUDY SELECTION The review of PNAC/PNALD has been divided into 4 areas to simplify one's understanding of the current knowledge regarding the pathogenesis and treatment of this disease: (1) nonnutrient risk factors associated with PNAC, (2) PNAC and lipid emulsions, (3) nutritional (nonlipid) considerations in the prevention of PNAC, and (4) supplemental medications in the prevention and treatment of PNAC. RESULTS The data for each topic area relevant to the clinical practice of pediatric surgery were reviewed, evaluated, graded, and summarized. CONCLUSIONS Although the conditions of PNAC and PNALD have been well recognized for more than 30 years, only a few concrete associations and treatment protocols have been established.

Abstract
PURPOSE OF REVIEW Functional gastrointestinal dysmotility is a common condition that affects premature infants. Delay in achievement of full enteral nutrition results in dependence on prolonged parenteral nutrition, predisposing to adverse outcomes. Studies in recent years show apparently conflicting results regarding the use of prokinetic agents in preterm infants. This review aims to evaluate these studies to determine whether use of these agents in premature infants is beneficial and justified. RECENT FINDINGS Randomized controlled trials in recent years have been performed to investigate the effectiveness of erythromycin in the treatment of nonobstructive gastrointestinal dysmotility in preterm infants. Overall, neither low-dose regimes nor prophylactic trials have been shown to be useful. High-dose regimes used as rescue therapy of infants with established gastrointestinal dysmotility have consistently shown clinical benefit. Theoretical risks of prolonged antibiotic use, such as emergence of antibiotic resistance and abnormal intestinal microbiota, have not been fully evaluated. SUMMARY Judicious use of high-dose erythromycin in premature infants as rescue therapy is probably justifiable. Further research in this area is warranted to develop newer prokinetic agents which may improve the safety profile of therapy.

Abstract
OBJECTIVES To evaluate the effectiveness of high-dose erythromycin to treat feeding intolerance in preterm infants predominantly fed milk formula. DESIGN This study is a prospective randomized controlled trial on 60 premature infants suffering from feeding intolerance. Thirty infants were given oral erythromycin ethylsuccinate at a dose of 50 mg/kg/day for 10 days or until they reached full enteral feeds. Randomization was stratified according to gestational age <32 weeks or ≥32 weeks gestation. The primary end point was the time taken to establish full enteral feeding since enrollment. Potential adverse effects associated with erythromycin were also monitored. Student's t test was used for comparison of continuous variables and χ(2)for categorical data. RESULTS In infants <32 weeks, the use of erythromycin was associated with more daily weight gain (12.8 ± 2.6 g vs. 9.2 ± 5.3 g, p = 0.04) compared to the control group. Time to reach full feed did not differ between the erythromycin (13.8 ± 3.9 days) and the control (17.46 ± 4.9 days) groups (p = 0.07). In infants ≥32 weeks, there were no differences between the erythromycin and the control groups. CONCLUSION High-dose erythromycin is associated with greater weight gain in preterm infants <32 weeks gestational age, who are predominantly fed cow's milk-based protein formulas.

Abstract
Preterm infants are highly susceptible to life-threatening infections that are clinically difficult to detect, such as late-onset septicemia and necrotizing enterocolitis (NEC). Here, we used a proteomic approach to identify biomarkers for diagnosis of these devastating conditions. In a case-control study comprising 77 sepsis/NEC and 77 nonsepsis cases (10 in each group being monitored longitudinally), plasma samples collected at clinical presentation were assessed in the biomarker discovery and independent validation phases. We validated the discovered biomarkers in a prospective cohort study with 104 consecutively suspected sepsis/NEC episodes. Proapolipoprotein CII (Pro-apoC2) and a des-arginine variant of serum amyloid A (SAA) were identified as the most promising biomarkers. The ApoSAA score computed from plasma apoC2 and SAA concentrations was effective in identifying sepsis/NEC cases in the case-control and cohort studies. Stratification of infants into different risk categories by the ApoSAA score enabled neonatologists to withhold treatment in 45% and enact early stoppage of antibiotics in 16% of nonsepsis infants. The negative predictive value of this antibiotic policy was 100%. The ApoSAA score could potentially allow early and accurate diagnosis of sepsis/NEC. Upon confirmation by further multicenter trials, the score would facilitate rational prescription of antibiotics and target infants who require urgent treatment.

Abstract
OBJECTIVE To assess if being small for gestational age impacts parenteral nutrition-associated cholestasis (PNAC) development. STUDY DESIGN We reviewed all the very low-birth weight infants exposed to parenteral nutrition for >14 days from 1996 to 2006, comparing auxological and clinical data, as well as nutritional history, during the first 4 weeks of life of infants with cholestasis and control subjects. RESULTS Of 445 very low-birth weight infants, 55 had development of PNAC. Infants with cholestasis had lower birth weight and gestational age but similar birth weight z-score compared with infants without cholestasis, and they received a lower amount of enteral feeds (25.8 +/- 20.7 vs 67.9 +/- 33.0 mL/kg, P < .001), a greater amount of intravenous glucose (10.6 +/- 1.3 vs 7.5 +/- 2.5 g/kg, P < .0001), lipids (1.8 +/- 0.4 vs 1.3 +/- 0.5, P < .0001) and proteins (2.7 +/- 0.5 vs 1.9 +/- 0.7, P < .0001), and needed a higher number of days of fasting (13.2 +/- 6.7 vs 6.5 +/- 4.8, P < .001). Enteral intake between 0 and 21 days of life (OR 0.66; 95% CI 0.53, 0.81, P < .0001) and oxygen therapy (OR 1.05; 95% CI 1.01, 1.09; P = .030) were identified as the best independent predictors of PNAC. CONCLUSIONS Enteral feeding remains the main factor for the prevention of PNAC, whereas small for gestational age infants do not have a higher risk of PNAC.

Abstract
BACKGROUND Pregnancies complicated by abnormal umbilical artery Doppler blood flow patterns often result in the baby being born both preterm and growth-restricted. These babies are at high risk of milk intolerance and necrotising enterocolitis, as well as post-natal growth failure, and there is no clinical consensus about how best to feed them. Policies of both early milk feeding and late milk feeding are widely used. This randomised controlled trial aims to determine whether a policy of early initiation of milk feeds is beneficial compared with late initiation. Optimising neonatal feeding for this group of babies may have long-term health implications and if either of these policies is shown to be beneficial it can be immediately adopted into clinical practice. METHODS AND DESIGN Babies with gestational age below 35 weeks, and with birth weight below 10th centile for gestational age, will be randomly allocated to an "early" or "late" enteral feeding regimen, commencing milk feeds on day 2 and day 6 after birth, respectively. Feeds will be gradually increased over 9-13 days (depending on gestational age) using a schedule derived from those used in hospitals in the Eastern and South Western Regions of England, based on surveys of feeding practice. Primary outcome measures are time to establish full enteral feeding and necrotising enterocolitis; secondary outcomes include sepsis and growth. The target sample size is 400 babies. This sample size is large enough to detect a clinically meaningful difference of 3 days in time to establish full enteral feeds between the two feeding policies, with 90% power and a 5% 2-sided significance level. Initial recruitment period was 24 months, subsequently extended to 38 months. DISCUSSION There is limited evidence from randomised controlled trials on which to base decisions regarding feeding policy in high risk preterm infants. This multicentre trial will help to guide clinical practice and may also provide pointers for future research. TRIAL REGISTRATION Current Controlled Trials ISRCTN: 87351483.

Abstract
INTRODUCTION The morbidity associated with prematurity occasionally leads to the use of prolonged parenteral nutrition, with the subsequent development of cholestasis being one of its complications. PATIENTS AND METHODS This is a two year retrospective study which compared biochemical markers of liver damage and cholestasis in premature babies who received or did not receive urso-deoxycholic acid for parenteral nutrition associated cholestasis. RESULTS Of a total of 24 recruited patients 17 received urso-deoxycholic acid and 7 did not. In the treated group significant decreases (P<0.05) in gamma-glutamyltranspeptidase and conjugated bilirubin were found after four and five weeks of treatment, respectively. Moreover, a significant correlation (P<0.01) between conjugated bilirubin and duration of total parenteral nutrition was established. CONCLUSIONS Patients who were promptly treated with urso-deoxycholic acid showed a more rapid decrease in biochemical markers of cholestasis, but not of cytotoxicity in the hepatobiliary complications secondary to prolonged parenteral nutrition. However, the present study has limitations derived from its design and therefore it would be desirable launch a randomized trial with sufficient power to evaluate the benefits derived from prophylactic or therapeutic use of urso-deoxycholic acid in the hepatobiliary conditions associated with the prolonged use of parenteral nutrition in the premature infants.

Abstract
INTRODUCTION With increasing survival rates, intestinal transplantation (ITx) and multivisceral transplantation have reached the mainstream of medical care. Pediatric candidates for ITx often suffer from severe multisystem impairments that pose challenges to the medical team. These patients frequently require intensive care preoperatively and have unique intensive care needs postoperatively. METHODS We reviewed the literature on intensive care of pediatric intestinal transplantation as well as our own experience. This review is not aimed only at pediatric intensivists from ITx centers; these patients frequently require ICU care at other institutions. RESULTS Preoperative management focuses on optimization of organ function, minimizing ventilator-induced lung injury, preventing excessive edema yet maintaining adequate organ perfusion, preventing and controlling sepsis and bleeding from varices at enterocutaneous interfaces, and optimizing nutritional support. The goal is to extend life in stable condition to the point of transplantation. Postoperative care focuses on optimizing perfusion of the mesenteric circulation by maintaining intravascular volume, minimizing hypercoagulability, and providing adequate oxygen delivery. Careful monitoring of the stoma and its output and correction of electrolyte imbalances that may require renal replacement therapy is critical, as are monitoring for and aggressively treating infections, which often present with only subtle clinical clues. Signs of intestinal rejection may be non-specific, and early differentiation from other causes of intestinal dysfunction is important. Understanding of the expanding armamentarium of immunosuppressive agents and their side-effects is required. CONCLUSIONS As outcomes of ITx improve, transplant teams accept patients with higher pre-operative morbidity and at higher risk for complications. Many ITx patients would benefit from earlier referral for transplant evaluation before severe liver disease, recurrent central venous catheter-related sepsis and venous thromboses develop.

Abstract
OBJECTIVE To identify small for gestational age (SGA) as an independent risk factor for parenteral nutrition-associated cholestasis (PNAC). STUDY DESIGN In a case-control study, records of infants treated in the neonatal intensive care unit from 1994 through 2003 with gestational ages (GA) < 34 weeks and exposure to parenteral nutrition (PN) > or = 7 days were reviewed. The primary outcome was the incidence of cholestasis in infants who were SGA. Secondary outcomes included PN duration, age at full enteral nutrition (FEN) and incidence of late-onset sepsis, necrotizing enterocolitis (NEC) and bronchopulmonary dysplasia (BPD). Analysis was by t test, logistic regression, and chi2 analysis. RESULTS Cases (n = 79) and control subjects (n = 152) had similar birth weights and GA (963 +/- 465 g versus 1090 +/- 463 g; 27 +/- 2 weeks versus 27 +/- 2 weeks; [mean +/- SD]). Of the infants who were SGA, 58% developed cholestasis (OR = 3.3, P < .01). Infants with cholestasis achieved FEN later (43 +/- 25 days versus 23 +/- 11 days) and had higher rates of sepsis (80% versus 34%), NEC (51% versus 7%), and BPD (65% versus 25%; P < .01). Of infants with cholestasis, infants who were SGA received fewer days of PN than infants who were appropriate for GA (49 +/- 24 days versus 68 +/- 36 days, P = .024). CONCLUSION Being SGA is an independent risk factor for PNAC. Infants who are SGA require less PN for cholestasis to develop.

BACKGROUND Routine total parenteral nutrition (TPN) in neonatal care can result in hepatic dysfunction in 40-60% of patients, most commonly as fatty liver, but little work has been conducted on the underlying mechanisms causing hepatic dysfunction. OBJECTIVE To use a piglet model for the premature human neonate on TPN, supplemented with lipid emulsions, to investigate hepatic responses. METHOD Piglets were delivered 2 days prematurely. Six control piglets were fed enterally (E), whilst twelve animals were maintained on TPN. TPN piglets received the standard TPN solution plus the lipid emulsion as either ClinOleic(R) (C, n = 6) or Intralipid(R) (I, n = 6). Hepatic lipid content and the fatty acid composition of liver triacylglyercol (TAG) as well as hepatic lipase (HL) activity were determined. Lipoprotein lipase (LPL) activity was measured in the liver, muscle and adipose tissue. The plasma concentrations of choline, bilirubin, TAG and non-esterified fatty acids (NEFA) were also measured. RESULTS Liver lipid was significantly increased in piglets on TPN and the tissue fatty acid profiles reflected the lipid emulsion. HL and LPL activities were reduced in liver but LPL increased in adipose tissue during TPN. Plasma concentrations of choline, bilirubin, TAG and NEFA were similar across the treatments. CONCLUSIONS The results suggest fatty liver occurs in neonates receiving TPN and the source of the accumulated lipid appears to be the lipid emulsion used. The factors regulating lipase activity during TPN require further study. The piglet can be used as a model for neonatal TPN.

Abstract
BACKGROUND & AIMS Feeding intolerance because of functional gastrointestinal dysmotility and parenteral nutrition-associated cholestasis (PNAC) are common problems in preterm, very-low-birth-weight (VLBW) infants. This double-blind, randomized, placebo-controlled study aimed to assess the effectiveness of "high-dose" oral erythromycin as a prokinetic agent in decreasing the incidence of PNAC. Two secondary end points, including the time to achieve full enteral feeding and the duration of parenteral nutrition, were also evaluated. METHODS Infants consecutively admitted to the neonatal unit were randomized to receive erythromycin (12.5 mg/kg/dose every 6 hours for 14 days) or an equivalent volume of normal saline (placebo) if they attained less than half the total daily fluid intake (<75 mL/kg/day) as milk feeds on day 14 of life. RESULTS Of 182 VLBW infants enrolled, 91 received erythromycin. The incidence of PNAC was significantly lower in erythromycin-treated infants (18/91) compared with placebo infants (37/91; P = .003). Treated infants achieved full enteral nutrition significantly earlier (mean, 10.1; SE, 1.7 days; P < .001), and the duration of parenteral nutrition was also significantly decreased by 10 days (P < .001). Importantly, fewer infants receiving erythromycin had 2 or more episodes of septicemia (n = 4) compared with placebo patients (n = 13, P = .03). No serious adverse effect was associated with erythromycin treatment. CONCLUSIONS High-dose oral erythromycin can be considered as a rescue measure for VLBW infants who fail to establish adequate enteral nutrition and in whom anatomically obstructive pathologies of the gastrointestinal tract have been excluded.

Abstract
BACKGROUND There is conflicting evidence as to whether ursodeoxycholic acid (UDCA) reduces the incidence of parenteral nutrition-associated cholestasis. AIM To investigate the efficacy of UDCA on parenteral nutrition-associated cholestasis in children with intestinal failure due to short bowel syndrome or to other causes. METHODS Children with cholestasis received 30 mg/kg/day UDCA. Improvement or normalization of parenteral nutrition-associated cholestasis was evaluated at 6 months of therapy and at the last follow-up. In a subgroup of children, serum UDCA levels were measured while receiving UDCA and after 4 weeks withdrawal. RESULTS Twelve children were treated with UDCA. Full remission or partial improvement of parenteral nutrition-associated cholestasis occurred in 11 of 12 children. In three of four children, withdrawal of UDCA was associated with a rebound rise of cholestasis. Only one of 12 treated children showed no improvement and in this patient, in contrast to four other patients, plasma levels of UDCA did not increase during treatment. CONCLUSIONS Ursodeoxycholic acid was effective in controlling parenteral nutrition-associated cholestasis. The efficacy of UDCA also in children with short bowel is related to intestinal absorption.

Abstract
Infectious burden of gut injury (G-INJ) associated with necrotizing enterocolitis (NEC) or with spontaneous intestinal perforation (SIP) in neonates has not been ascertained. We sought to test the hypotheses that: (1) infants with G-INJ develop higher number of infections including non-concurrent infections than infants without G-INJ in a neonatal intensive care unit (NICU); (2) surgical debridement (DEB) of infants with severe G-INJ is associated with lower infectious morbidity and mortality. All infants admitted to the regional NICU from October 1991 to February 2003 were included in this prospective prevalence investigation of G-INJ and infections. Non-viable (<23 week gestational age) infants, infants with congenital anomalies, and those who developed NEC after SIP were excluded. Standard definitions of National Centers for Disease Control and Prevention were used for different categories of infections. Episodes of infections were classified as concurrent or non-concurrent (post G-INJ) based upon their timing in association with G-INJ. Infants with G-INJ associated with Bell stage II or higher NEC or with SIP were further stratified by DEB into two subgroups. A previously described 7-point clinical score was used to divide G-INJ into mild (0-2), moderate (3-5), and severe (6-7) categories. Surgical outcomes were determined by using chi(2) and logistic regression analyses. Data are expressed as mean +/- SD or as odds ratio (OR) with 95% confidence intervals (CI); P < 0.05 was considered significant. Of all 5,481 infants, 954 (17.4%) developed 1,734 episodes of infections. Prevalence of G-INJ was 4% (n = 222); of these, 33% (n = 73) underwent DEB. Infants with G-INJ had lower mean birth weight (1,414+/-766 vs. 2,153+/-104 g; P < 0.0001) and lower mean gestational age (29.6+/-4.2 vs. 32.9+/-4.8 weeks; P < 0.0001) than their peers (n = 5,259). Controlling for birth weight and gestational age, odds for non-concurrent blood stream infections (BSIs) in G-INJ infants were higher (OR 13.98, CI 10.289-19.01, P < 0.0001) than the remaining population without G-INJ. Forty-four percent of all episodes of fungemia, 32% of all episodes of BSIs occurred in G-INJ infants (P < 0.0001). Within the G-INJ group, there were no demographic differences between the DEB and non-DEB infants. Controlling for severity of G-INJ, odds for non-concurrent BSIs (OR 3.45, CI 1.04-11.36, P < 0.05) and for mortality (OR 3.35, CI 1-10, P < 0.05) among non-DEB infants were higher than in DEB infants. Infants with G-INJ suffered from a disproportionate number of all blood-stream infections in our intensive care nursery. Infants with severe G-INJ whose management includes DEB are more likely to survive and to incur less infectious morbidity.

Abstract
BACKGROUND It often takes several days or even weeks to establish full enteral feeds (FEFs) in preterm, especially extremely low birthweight neonates because of feed intolerance related to gastrointestinal hypomotility. Clinical trials of erythromycin as a prokinetic agent in preterm neonates have reported conflicting results. AIM To systematically review the efficacy and safety of erythromycin as a prokinetic agent in preterm neonates. METHODS Only randomised controlled trials in preterm neonates (gestation < or = 37 weeks) were considered eligible for inclusion. The primary outcome was the time to reach FEFs of 150 ml/kg/day. The secondary outcomes included the incidence of erythromycin related adverse effects such as diarrhoea, cardiac arrhythmias, and hypertrophic pyloric stenosis. No restrictions were applied on the dose (low: 3-12 mg/kg/day; antimicrobial: > or = 12 mg/kg/6-8 hours) and route (oral or intravenous) and mode (prophylactic or rescue) of administration. The standard methodology for systematic reviews was followed. A subgroup analysis was pre-planned based on the dose and mode of drug administration. RESULTS Seven trials (three prophylaxis, four rescue) with various doses, routes and modes of administration, and durations of erythromycin treatment and different results were found to be eligible for inclusion in the analysis. Meta-analysis could not be performed, as specific data were either inadequate or not available. CONCLUSION The conflicting trial results may be explained by differences in dose and route and mode of administration of erythromycin and in gastrointestinal motor responses in the presence of different feeding conditions-for example, fasting v fed state, intermittent v continuous feeds. Gestational and postnatal ages during erythromycin treatment are also important.
