Abstract
Introduction The diagnosis of biliary atresia (BA) remains challenging, and there is still uncertainty regarding the optimal time to perform a Kasai portoenterostomy (KPE). Little is known about the difficulties in the diagnosis and outcomes of BA in preterm infants (PBA). This study, which represents the first Italian report of preterm infants with BA, aims to describe a single-center experience of BA in preterm newborns. Methods We retrospectively reviewed all infants consecutively diagnosed with BA who underwent a Kasai procedure at the Bambino Gesù Children's Hospital between January 1998 and December 2021. Prematurity was defined as a gestational age (GA) of <37 weeks. Demographic, laboratory, and histology data were recorded, and the main outcomes considered were clearance of jaundice (COJ), native liver survival, and mortality. Results A total of 21 PBA were compared with 117 term BA controls (TBA). The median GA of PBA was 35.1 (32-36.1) weeks, with a mean birth weight of 2,100 (1,897-2,800) g. Age at first presentation was significantly lower in PBA patients: 46 (22-68) vs. 61 (44-72) days; p = 0.02. The median age at KPE was similar between the two groups: 70 days (33 corrected) for PBA vs. 67 in TBA; p = 0.8. At the time of surgery, median serum bilirubin was lower in the PBA group (7.7 vs. 8.6 mg/dl, p = 0.04). Similarly, the median APRi at the time of KPE was lower but not significant in the PBA group: 1.09 vs. 1.16; p = 0.8. No differences were found in terms of COJ between the PBA and TBA groups: n = 9 (43%) vs. 34 (35%); p = 0.2. Overall native liver survival was similar between the two groups: 8.6 (4.8-12.2) for the PBA group vs. 7.6 (5.6-9.5) years for the TBA group with no significant differences; p = 0.45. Post-KPE native liver survival was similar between the two groups: 38% vs. 52% at 5 years for the TBA and PBA groups, respectively; p = 0.54. Conclusion The PBA and TBA groups appear to have similar outcomes in terms of COJ, overall native liver survival, and 5-year liver survival. Considering the corrected GA, early KPE is related to lower cholestatic damage. Further multicenter studies are required.

Abstract
In preterm neonates unable to obtain sufficient oral nutrition, intravenous lipid emulsion is life-saving. The contribution of post-conceptional level of maturation to pathology that some neonates experience is difficult to untangle from the global pathophysiology of premature birth. In the present study, we determined fetal physiological responses to intravenous lipid emulsion. Fetal sheep were given intravenous Intralipid 20® (n = 4 females, 7 males) or Lactated Ringer's Solution (n = 7 females, 4 males) between 125 ± 1 and 133 ± 1 d of gestation (term = 147 d). Manufacturer's recommendation for premature human infants was followed: 0.5-1 g/kg/d initial rate, increased by 0.5-1 to 3 g/kg/d. Hemodynamic parameters and arterial blood chemistry were measured, and organs were studied postmortem. Red blood cell lipidomics were analyzed by LC-MS. Intravenous Intralipid did not alter hemodynamic or most blood parameters. Compared with controls, Intralipid infusion increased final day plasma protein (P=0.004; 3.5 ± 0.3 vs. 3.9 ± 0.2 g/dL), albumin (P = 0.031; 2.2 ± 0.1 vs. 2.4 ± 0.2 g/dL), and bilirubin (P<0.001; conjugated: 0.2 ± 0.1 vs. 0.6 ± 0.2 mg/dL; unconjugated: 0.2 ± 0.1 vs. 1.1 ± 0.4 mg/dL). Circulating IGF-1 decreased following Intralipid infusion (P<0.001; 66 ± 24 vs. 46 ± 24 ng/mL). Compared with control Oil Red O liver stains (median score 0), Intralipid-infused fetuses scored 108 (P=0.0009). Lipidomic analysis revealed uptake and processing of infused lipids into red blood cells, increasing abundance of saturated fatty acids. The near-term fetal sheep tolerates intravenous lipid emulsion well, although lipid accumulates in the liver. Increased levels of unconjugated bilirubin may reflect increased red blood cell turnover or impaired placental clearance. Whether Intralipid is less well tolerated earlier in gestation remains to be determined.

Abstract
BACKGROUND Reference guidelines for neonatal conjugated hyperbilirubinemia (cholestasis) management use a uniform approach regardless of gestational age (GA). We hypothesize that the clinical pattern of neonatal cholestasis is tightly related to GA. The aim of this study was to describe the effects of GA on neonatal cholestasis. METHODS A retrospective 4-year cohort study in a 70-bed neonatal care unit. Neonates with conjugated bilirubin≥34.2μmol/L (2 mg/dL) were identified. The incidence, clinical characteristics, etiology, treatment, and prognosis were compared between infants <32 and≥32 weeks GA. RESULTS Overall incidence of cholestasis was 4% (125/3402). It was >5 times higher and the mean duration was >1.5 times longer in neonates <32 weeks GA (10% versus 1.8%, p <0.01 and 49 versus 31 days, p <0.01, respectively). The onset of cholestasis was later in neonates <32 weeks (22 versus 10 days of life, p <0.001). This later onset of cholestasis was associated with parenteral nutrition, whereas the earlier onset was associated with other causes. Treatment using fish oil lipids was more frequently administrated to infants <32 weeks GA, whereas Ursodeoxycholic acid was administrated more frequently in≥32 weeks GA. Cholestasis resolved during hospitalization in 73% of <32 versus 38% in≥32 weeks GA infants (p <0.01). CONCLUSIONS The incidence, clinical presentation, etiology, treatment, and clinical evolution of neonatal cholestasis were all significantly affected by GA. Our results support the use of a GA-oriented approach for the management of neonatal cholestasis.

Abstract
BACKGROUND In neonates, uncontrolled pain and opioid exposure are both correlated with short- and long-term adverse events. Therefore, managing pain using opioid-sparing approaches is critical in neonatal populations. Multimodal pain control offers the opportunity to manage pain while reducing short- and long-term opioid-related adverse events. Intravenous (IV) acetaminophen may represent an appropriate adjunct to opioid-based postoperative pain control regimes. However, no trials assess this drug in patients less than 36 weeks post-conceptual age or weighing less than 1500 g. OBJECTIVE The proposed study aims to determine the feasibility of conducting a randomized control trial to compare IV acetaminophen and fentanyl to a saline placebo and fentanyl for patients admitted to the neonatal intensive care unit (NICU) undergoing major abdominal or thoracic surgery. METHODS AND DESIGN This protocol is for a single-centre, external pilot randomized controlled trial (RCT). Infants in the NICU who have undergone major thoracic or abdominal surgery will be enrolled. Sixty participants will undergo 1:1 randomization to receive intravenous acetaminophen and fentanyl or saline placebo and fentanyl. After surgery, IV acetaminophen or placebo will be given routinely for eight days (192 hours). Appropriate dosing will be determined based on the participant's gestational age. Patients will be followed for eight days after surgery and will undergo a chart review at 90 days. Primarily feasibility outcomes include recruitment rate, follow-up rate, compliance, and blinding index. Secondary clinical outcomes will be collected as well. CONCLUSION This external pilot RCT will assess the feasibility of performing a multicenter RCT comparing IV acetaminophen and fentanyl to a saline placebo and fentanyl in NICU patients following major abdominal and thoracic surgery. The results will inform the design of a multicenter RCT, which will have the appropriate power to determine the efficacy of this treatment.

Abstract
Cholestasis affects 2% of newborns admitted to the neonatal intensive care unit and 20% of premature infants and requires a thoughtful evaluation and diagnostic workup.There may be a single responsible etiology, or its development may be multifactorial. Premature neonates are especially predisposed because of their increased risk of infections and acute illness, need for parenteral nutrition, and exposure to certain medications. Clinically, an infant may present with jaundice, evidence of hepatic injury, or worsening hepatic function. Diagnosis may be made in consultation with various pediatric subspecialists including gastroenterology, genetics, and surgery. Treatment depends on the etiology but may include medications or surgical interventions. Timely recognition and intervention improve outcomes. [Pediatr Ann. 2023;52(8):e297-e302.].

Abstract
OBJECTIVE To describe the incidence and to analyze risk factors associated with cholestasis in neonates with gastroschisis. METHODS This is a retrospective cohort study in a tertiary single center analyzing 181 newborns with gastroschisis between 2009 and 2020. The following risk factors associated with cholestasis were analyzed: gestational age, birth weight, type of gastroschisis, silo closure or immediate closure, days of parenteral nutrition, type of lipid emulsion, days of fasting, days to reach a full diet, days with central venous catheter, presence of infections, and outcomes. RESULTS Among the 176 patients evaluated, 41 (23.3%) evolved with cholestasis. In the univariate analysis, low birth weight (p=0.023), prematurity (p<0.001), lipid emulsion with medium-chain triglycerides and long-chain triglycerides (p=0.001) and death (p<0.001) were associated with cholestasis. In the multivariate analysis, patients who received lipid emulsion with fish oil instead of medium chain triglycerides/long chain triglycerides (MCT/LCT) emulsion had a lower risk of cholestasis. CONCLUSIONS Our study shows that lipid emulsion with fish oil is associated with a lower risk of cholestasis in neonates with gastroschisis. However, this is a retrospective study and a prospective study should be performed to confirm the results.

Abstract
Necrotizing enterocolitis (NEC), spontaneous intestinal perforation (SIP) and meconium-related ileus (MI) requiring surgical intervention are associated with a high risk of severe short- and long-term complications in very-low-birth-weight (VLBW) infants including poor growth, cholestasis and neurodevelopmental impairment. This retrospective study aimed to identify risk factors for such complications in a cohort of 55 VLBW preterm infants requiring surgery with enterostomy creation due to NEC, SIP or MI. Long-term follow-up was available for 43 (78%) infants. Multiple regression analyses revealed that the duration of inflammation and longitudinal growth determined the risk of cholestasis and neurodevelopmental outcome at 2 years corrected age independent of the aetiology of the intestinal complication. Direct bilirubin increased by 4.9 μmol/L (95%CI 0.26-9.5), 1.4 μmol/L (95%CI 0.6-2.2) and 0.8 μmol/L (95%CI 0.22-1.13) with every day of elevated (Interleukin-6) IL-6, (C-reactive protein) CrP and parenteral nutrition. The mental development index at 2 years corrected age decreased by 3.8 (95%CI -7.3--0.36), 0.4 (95%CI 0.07-0.80) and 0.3 (95%CI 0.08-0.57) with every day of elevated IL-6 and every 1 point decrease in weight percentile at discharge and 2 years. These data stress the importance of optimal timing for the initial surgery in order to prevent prolonged inflammation and an early reversal of the enterostomy in case of poor growth or insufficient enteral nutrition.

Abstract
BACKGROUND The advantage of breast milk feeding, and supplementation of probiotics is well known and proven. However, the lack of reliable amounts of colostrum and/or transient breast milk during the first few postnatal days might inhibit timely enteral nutrition. METHODS The aim of this nationwide survey in German Level-1 neonatal intensive care units (NICUs) was to collect data regarding the management of feeding in the first days of life in very low birth weight infants (VLBWIs, birth weight<1500 g). In addition, we analyzed differences in the use of probiotics. An online survey was sent to all 163 Level-1 NICUs in Germany. RESULTS 110/163 (67.5%) hospitals participated in our study. One-fifth of all participants used exclusively breast milk. The reported incidence of necrotizing enterocolitis (NEC) was lower in NICUs that exclusively used breast milk in VLBWIs (p=0.08). Two-thirds start enteral feeding independent of gestational age during the first 12 hours postnatally with either breast milk or formula. 80% of all participants checked gastric residuals routinely. The use of probiotics differs widely concerning duration and interruption during antibiotic therapy. CONCLUSION The exclusive use of breast milk is associated with a lower incidence of NEC. The result of our survey emphasizes the paramount importance of nutrition with mother`s milk. In case of insufficient availability of mother`s milk, the use of human donor milk still appears to be superior to formula feeding. The implementation of human donor milk banks should therefore be promoted.

Abstract
Cholestasis refers to impaired bile flow from the liver to the intestine. In neonates, cholestasis causes poor growth and may progress to liver failure and death. Normal bile flow requires an intact liver-gut-microbiome axis, whereby liver-derived primary bile acids are transformed into secondary bile acids. Microbial bile salt hydrolase (BSH) enzymes are responsible for the first step, deconjugating glycine- and taurine-conjugated primary bile acids. Cholestatic neonates often are treated with the potent choleretic bile acid ursodeoxycholic acid (UDCA), although interactions between UDCA, gut microbes, and other bile acids are poorly understood. To gain insight into how the liver-gut-microbiome axis develops in extreme prematurity and how cholestasis alters this maturation, we conducted a nested case-control study collecting 124 stool samples longitudinally from 24 preterm infants born at mean 27.2 ± 1.8 weeks gestation and 946 ± 249.6 g, half of whom developed physiologic cholestasis. Samples were analyzed by whole metagenomic sequencing, in vitro BSH enzyme activity assays optimized for low biomass fecal samples, and quantitative mass spectrometry to measure the bile acid metabolome. In extremely preterm neonates, acquisition of the secondary bile acid biosynthesis pathway and BSH genes carried by Clostridium perfringens are the most prominent features of early microbiome development. Cholestasis interrupts this developmental pattern. BSH gene abundance and enzyme activity are profoundly reduced in cholestatic neonates, resulting in decreased quantities of unconjugated bile acids. UDCA restores total fecal bile acid levels in cholestatic neonates, but this is due to a 522-fold increase in fecal UDCA. A majority of bile acids in early development are atypical positional and stereo-isomers of bile acids. We report novel associations linking isomeric bile acids and BSH activity to neonatal growth trajectories. These data highlight deconjugation of bile acids as a key microbial function that is acquired in early neonatal development and impaired by cholestasis.

Abstract
Objective: To assess the risk of necrotizing enterocolitis (NEC) and explore the relationship between antibiotic overexposure and disease occurrence in a large prospective birth cohort.Methods: Based on a prospective birth cohort, the study collected hospitalization data of very preterm infants (VPIs) having gestational age of less than 32 weeks from January 1, 2018, to June 30, 2021 via the China Northern Neonatal Network. Infants diagnosed with NEC ≥ stage II were included in the case group, and each case was matched for GA and birth weight for the control group. Furthermore, the risk factors for NEC were determined by statistical analyses.Results: A total of 6425 VPIs were included in this study, and 167 (2.6%) of these subjects were diagnosed with NEC ≥ stage II. The study also included 984 extremely preterm infants (gestational age <28 weeks), including 50 (5.1%) infants diagnosed with NEC ≥ stage II. In the matched case-control study, subjects had a total of antibiotic days-of-therapy for 9015 days, of which broad-spectrum antibiotics (BSAs) accounted for 77%. The antibiotic spectrum index per antibiotic day in the case group was significantly higher and was an independent risk factor for the occurrence of NEC (p = 0.001, OR = 1.13).Conclusion: The cohort of VPIs was overexposed to antiboitics. Unreasonable combination of antibiotics and overexposure to BSAs may increase the risk of NEC in preterm infants.

Abstract
The accumulation of bile acids in the liver leads to the development of cholestasis and hepatocyte injury. Nuclear receptors control the synthesis and transport of bile acids in the liver. Among them, the farnesoid X receptor (FXR) is the most common receptor studied in treating cholestasis. The activation of this receptor can reduce the amount of bile acid synthesis and decrease the bile acid content in the liver, alleviating cholestasis. Ursodeoxycholic acid (UDCA) and obeticholic acid (OCA) have a FXR excitatory effect, but the unresponsiveness of some patients and the side effect of pruritus seriously affect the results of UDCA or OCA treatment. The activator of peroxisome proliferator-activated receptor alpha (PPARα) has emerged as a new target for controlling the synthesis and transport of bile acids during cholestasis. Moreover, the anti-inflammatory effect of PPARα can effectively reduce cholestatic liver injury, thereby improving patients’ physiological status. Here, we will focus on the function of PPARα and its involvement in the regulation of bile acid transport and metabolism. In addition, the anti-inflammatory effects of PPARα will be discussed in some detail. Finally, we will discuss the application of PPARα agonists for cholestatic liver disorders.

Abstract
BACKGROUND In the pediatric group, most cholestatic patients had disease onset at 0-3 months of age, and more and more are found to have specific genetic defects after failing to obtain a definite diagnosis by routine evaluation. To investigate the etiological diagnosis for the newborns with cholestasis during the neonatal period after emerging molecular tests comprehensively. METHODS We conducted a retrospective study to evaluate clinical characteristics, etiologies and outcomes in infants with neonatal cholestasis after emerging molecular diagnostics from January 1st to December 31st, 2019 in Children's Hospital of Fudan University. RESULTS There were 160 cases of neonatal cholestasis with mean gestational age (GA) 32.6±4.8 weeks and birth weight (BW) 1,880±991 g, composing 3.4% of total neonatal admissions in 2019. Overall 97.5% (n=156) patients had a definite diagnosis, including 9 obtaining a genetic diagnosis after adding molecular test in routine evaluation, which made the diagnosis rate for cholestasis increased by 5.6%. The most common etiology of cholestasis in the neonatal period was parenteral nutrition-associated cholestasis (PNAC) 48.8% (n=78), followed by cardiovascular and circulatory disorders 18.1%, biliary anatomic obstruction 12.5%, infection 8.7% and genetic disorders 5.6%. PNAC and biliary anatomic obstruction were the most common etiology of cholestasis for preterm and term infants respectively. The mortality rate is 2.5% (n=4) and 91.9% (n=147) patients totally recovery or improve in follow-up. CONCLUSIONS The causes of cholestasis in neonates are complicated, molecular diagnostics can improve the etiological diagnosis for newborns with cholestasis. But still, quite amount of causes are remediable and transient during the neonatal period, gene test may help to rule out genetic causes and enhance confidence in judging prognosis.

Providing the Best Parenteral Nutrition before and after Surgery for NEC: Macro and Micronutrients Intakes. Nutrients 2022; 14:nu14050919.

Abstract
Necrotizing enterocolitis (NEC) is the main gastrointestinal emergency of preterm infants for whom bowel rest and parenteral nutrition (PN) is essential. Despite the improvements in neonatal care, the incidence of NEC remains high (11% in preterm newborns with a birth weight <1500 g) and up to 20−50% of cases still require surgery. In this narrative review, we report how to optimize PN in severe NEC requiring surgery. PN should begin as soon as possible in the acute phase: close fluid monitoring is advocated to maintain volemia, however fluid overload and electrolytes abnormalities should be prevented. Macronutrients intake (protein, glucose, and lipids) should be adequately guaranteed and is essential in each phase of the disease. Composite lipid emulsion should be the first choice to reduce the risk of parenteral nutrition associated liver disease (PNALD). Vitamin and trace elements deficiency or overload are frequent in long-term PN, therefore careful monitoring should be planned starting from the recovery phase to adjust their parenteral intake. Neonatologists must be aware of the role of nutrition especially in patients requiring long-term PN to sustain growth, limiting possible adverse effects and long-term deficiencies.

Abstract
INTRODUCTION Glucocorticoids are currently used for the co-therapeutic management of autoimmune hepatitis and some cholestatic diseases. Thus far, we do not know the efficacy of glucocorticoids in the treatment of parenteral nutrition-associated cholestasis. We aimed to analyze whether the administration of late postnatal dexamethasone for treating bronchopulmonary dysplasia influence the occurrence of parenteral nutrition-associated cholestasis in preterm neonates. METHODS A retrospective study was conducted for 78 preterm neonates without major anomalies (gestational age was <30 weeks, and birthweight was ≤1000 g) hospitalized in a neonatal unit. Total and direct serum bilirubin levels were measured about every two weeks for all neonates. Data including the administration of dexamethasone, intravenous nutrition, and enteral feeding were collected by at least three audits. RESULTS A total of 15 preterm neonates were diagnosed with parenteral nutrition-associated cholestasis, and after stopping parenteral nutrition, the direct bilirubin value decreased to the normal level for no longer than 150 days. The prolonged duration of parenteral nutrition was a risk factor, and late postnatal dexamethasone treatment was a protective factor in reducing the incidence of parenteral nutrition-associated cholestasis. CONCLUSION Dexamethasone treatment may reduce the occurrence of parenteral nutrition-associated cholestasis in preterm neonates.

Abstract
Cholestatic jaundice is a common presenting feature of hepatobiliary and/or metabolic dysfunction in the newborn and young infant. Timely detection of cholestasis, followed by rapid step-wise evaluation to determine the etiology, is crucial to identify those causes that are amenable to medical or surgical intervention and to optimize outcomes for all infants. In the past 2 decades, genetic etiologies have been elucidated for many cholestatic diseases, and next-generation sequencing, whole-exome sequencing, and whole-genome sequencing now allow for relatively rapid and cost-effective diagnosis of conditions not previously identifiable via standard blood tests and/or liver biopsy. Advances have also been made in our understanding of risk factors for parenteral nutrition-associated cholestasis/liver disease. New lipid emulsion formulations, coupled with preventive measures to decrease central line-associated bloodstream infections, have resulted in lower rates of cholestasis and liver disease in infants and children receiving long-term parental nutrition. Unfortunately, little progress has been made in determining the exact cause of biliary atresia. The median age at the time of the hepatoportoenterostomy procedure is still greater than 60 days; consequently, biliary atresia remains the primary indication for pediatric liver transplantation. Several emerging therapies may reduce the bile acid load to the liver and improve outcomes in some neonatal cholestatic disorders. The goal of this article is to review the etiologies, diagnostic algorithms, and current and future management strategies for infants with cholestasis.

Abstract
Despite the recent advances involving molecular studies, the neonatal cholestasis (NC) diagnosis still relays on the expertise of medical teams. Our aim was to develop models of etiological diagnosis and unfavourable prognosis which may support a rationale diagnostic approach. We retrospectively analysed 154 patients born between January 1985 and October 2019. The cohort was divided into two main groups: (A) transient cholestasis and (B) other diagnosis (with subgroups) and also in two groups of outcomes: (I) unfavourable and (II) favourable. Multivariate logistic regression analysis identified the lower gestational age as the only variable independently associated with an increased risk of transient cholestasis and signs and/or symptoms of sepsis with infectious or metabolic diseases. Gamma-glutamyl transferase serum levels > 300 IU/L had a positive predictive value for both diagnosis of biliary atresia and for alpha-1-antitrypsin deficiency (A1ATD) and for unfavourable prognosis. A model of diagnosis for A1ATD (n = 34) showed an area under the ROC curve = 0.843 [confidence interval (CI): 0.773-0.912].Conclusion: This study identified some predictors of diagnosis and prognosis which helped to build a diagnostic decision algorithm. The unusually large subgroup of patients with A1ATD in this cohort emphasizes its predictive diagnostic model. What Is Known • The etiological diagnosis of neonatal cholestasis (NC) requires a step-by-step guided approach, and diagnostic models have been developed only for biliary atresia. • Current algorithms neither address the epidemiology changes nor the application of the new molecular diagnostic tools. What Is New • This study provides diagnostic predictive models for patients with A1ATD, metabolic/infectious diseases, and transient cholestasis, and two models of unfavourable prognosis for NC. • A diagnostic decision algorithm is proposed based on this study, authors expertise and the literature.

Abstract
OBJECTIVE Preterm infants receive long-term parenteral nutrition (PN) for gastrointestinal immaturity. This study aimed to determine if mixed lipid emulsions containing fish oil decrease the incidence of PN-associated cholestasis by reducing oxidative stress and providing an anti-inflammatory effect. METHODS This retrospective cohort study enrolled 399 very low birth weight premature infants (gestational age ≤32 weeks) between January 2009 and November 2017 at a single neonatal intensive care unit. Preterm infants received total PN with either mixed lipid emulsion including fish oil (SMOFlipid®, n = 195) or soybean oil-based lipid emulsion (Lipovenoes®, n = 204) for at least 7 days. We compared the outcomes of PN-associated cholestasis, comorbidities, and mortality between the groups. RESULTS The incidence of PN-associated cholestasis was significantly lower in the SMOFlipid group than in the Lipovenoes group. The duration to full feeding days was significantly shorter in the SMOFlipid group compared with the Lipovenoes group. Relevant complications, such as severe retinopathy of prematurity and bronchopulmonary dysplasia, were also significantly reduced in the SMOFlipid group compared with the Lipovenoes group. CONCLUSION In premature infants, PN with fish oil-based lipid emulsions is associated with a lower incidence of PN-associated cholestasis compared with soybean oil-based lipid emulsions.

Abstract
BACKGROUND In this study we sought to ascertain a critical threshold of the degree of prematurity and long-term digestive morbidity of the offspring. METHODS A population-based cohort analysis was conducted, comparing long-term incidence of digestive morbidity in infants born preterm. Cases were divided into four groups according to the extremity of prematurity. Digestive morbidity included hospitalizations involving a predefined set of ICD9 codes. A Kaplan-Meier survival curve was constructed to compare cumulative incidence of digestive morbidity. A Cox proportional hazards model was used to control for confounders. RESULTS During the study period 220,563 patients met the inclusion criteria. Offspring born preterm had significantly more hospitalizations due to digestive morbidity compared to term offspring. The Kaplan-Meier survival curve demonstrated significant higher cumulative incidence of long-term digestive morbidity of the offspring with decreasing gestational age (Log rank p < 0.001). The risk was highest at 28 weeks gestation. Using a Cox proportional hazards model, being born at very and moderate to late preterm birth was independently associated with long-term digestive morbidity. CONCLUSION Preterm delivery is an independent risk factor for long-term digestive morbidity of the offspring. In our population, 28 weeks gestation is the critical cut-off for pronounced digestive morbidity.

Abstract
The usefulness of serum alkaline phosphatase (ALP) and phosphorous in screening and monitoring of metabolic bone disease of prematurity (MBDP) still has some limitations, especially in preterm infants with concomitant conditions such as cholestasis. We aimed to assess a modification of serum ALP (M-ALP) as a biomarker for MBDP in preterm infants, and the use of ultrasound monitoring for the apparition of knee ossification centers as marker of bone mineralization. Biochemical and clinical registers were taken from 94 preterm newborns <32 weeks. A significant correlation existed between serum ALP and direct bilirubin (DB), expressed by the regression equation: M-ALP (IU/L) = 302.1 + 96.9 (DB (mg/dL)). The ratio ALP/M-ALP > 1 was demonstrated to be more specific (87.5%) in the diagnosis of MBDP than the cut-off value of serum ALP > 500 IU/L (62.5%). ALP/M-ALP > 1 showed 100% sensitivity and specificity for the diagnosis of MBDP, and a good correlation with specific bone ALP (B-ALP). Patients with the knee nucleus by post-menstrual week 37 had lower B-ALP compared to patients with no nucleus, and no patients with MBDP presented the nucleus by the 40th week. In the absence of reliable specific B-ALP, reinterpreting serum ALP values by M-ALP plus monitoring of knee ossification centers contribute to better management of MBDP in preterm infants with cholestasis.

METHODS VLBW infants receiving parenteral nutrition (PN) for at least 14 days were enrolled in a retrospective dual-centre study and divided into two groups chronologically: group A (2000-2007) and group B (2008-2015). The incidence of PNAC and related factors were investigated. We compared the differences between PNAC and non-PNAC groups. A multivariate binary logistic regression analysis was carried out to identify the potential risk factors of PNAC. RESULTS A total of 387 VLBW infants (53 in group A and 334 in group B) were enrolled in the study. The total incidence of PNAC was 6.7%, 9.4% in group A and 6.3% in group B. The dosage of amino acid (P = 0.009), glucose (P = 0.006), PN calories (P = 0.021) and the ratio of glucose/fat (P = 0.014) were significantly higher in group B than in group A. Non-protein energy to nitrogen ratio (P = 0.017) was lower in group B. Birthweight was significantly lower in the PNAC group than in the non-PNAC group (P = 0.021). Subgroup analysis showed that gestational age and duration of PN were significantly different between the PNAC and non-PNAC groups (P < 0.05). Logistic regression showed that prolonged duration of PN (≥43 days) (odds ratio 3.155, 95% confidence interval 1.009-9.861, P = 0.048) was an independent risk factor of PNAC. CONCLUSIONS For VLBW infants, prolonged duration of PN is a risk factor for the development of PNAC. PNAC may be prevented by weaning off PN as early as possible in VLBW infants.

[PMID: 33021740 DOI: 10.1002/jpen.2022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Revised: 09/03/2020] [Accepted: 09/20/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND The aim of the study was to assess the effects of computerized provider order entry (CPOE) for parenteral nutrition (PN) on selected clinical parameters of extremely low-birth-weight (ELBW) neonates in a tertiary neonatal intensive care unit. METHODS This study was a retrospective data analysis of preterm infants born over a 1-year period before and after introduction of CPOE. PN composition during the first 2 weeks of life, change in weight, head circumference and body length z-scores were assessed. Duration of PN and selected neonatal complications were compared. Logistic regression was used to adjust for confounding variables (sex, birth weight, and birth-gestational age). RESULTS Ninety-four patients in 2 equal groups were analyzed. Birth weight (median 810 vs 825 g) and gestational age (27 vs 27 weeks) were comparable. After adjustment for confounding variables, on the first and seventh day of life, significantly more energy (P < .001), protein (P < .001), lipid (P < .03), and carbohydrate (P < .02) were administered in the CPOE group than in the manually calculated (MC) prescriptions group. The CPOE group had lower weight loss (P < .001), a significant improvement in linear growth, and faster regain of birth weight (P < .01) compared with the MC group. CONCLUSION The CPOE positively influences the quality of PN in ELBW infants. It also significantly reduced initial weight loss, time to regain birth weight, and linear growth. It may also have beneficial effects on selected clinical outcomes, which requires further study.

Abstract
BACKGROUND Parenteral nutrition (PN) is crucial for the improvement of long-term outcomes in very low birth weight (VLBW) neonates. Lipid injectable emulsions are a key component of PN, as they contain essential fatty acids and provide energy critical for brain growth. Prolonged administration increases risk of intestinal failure-associated liver disease, including cholestasis, and other complications. METHODS This is a retrospective, quasi-experimental cohort study of 215 VLBW neonates. The primary outcome was a change in direct bilirubin concentration. Secondary outcomes included change in total bilirubin concentration and incidences of cholestasis and other disease states associated with PN and prematurity. Cholestasis was defined as direct bilirubin ≥ 1.0 mg/dL with total bilirubin < 5.0 mg/dL or direct bilirubin > 20% of total bilirubin with total bilirubin > 5.0 mg/dL. RESULTS Change in direct bilirubin concentration was not different between groups. Incidence of cholestasis was not different between groups per charted diagnosis or per study definition. Non-stage-0 retinopathy of prematurity, bronchopulmonary dysplasia, sepsis, and necrotizing enterocolitis were all lower in the mixed oil lipid emulsion group, which remained significant after adjustment for differences in gestational age, birth weight, and PN duration. CONCLUSIONS Although mixed oil lipid emulsion was not found to be associated with a lower risk of cholestasis, it may decrease risks of other disease states associated with PN therapy.

Abstract
Intestinal failure-associated liver disease (IFALD) is common in neonates who suffer from intestinal failure and rely on parenteral nutrition. The etiology is multifactorial, relating to the infant's underlying cause of intestinal failure and other infant factors such as prematurity. Management of the disease includes transitioning to enteral feedings as soon as is safe for the infant. In infants who continue to rely on parenteral nutrition, alternative lipid emulsions and other medications may be used. This article reviews the epidemiology and factors that contribute to IFALD in neonates, in addition to management strategies.

Abstract
Neonatal cholestasis is characterized by conjugated hyperbilirubinemia in the newborn and young infant and is a sign common to over 100 hepatobiliary and/or metabolic disorders. A timely evaluation for its etiology is critical in order to quickly identify treatable causes such as biliary atresia, many of which benefit from early therapy. An expanding group of molecularly defined disorders involving bile formation, canalicular transporters, tight junction proteins and inborn errors of metabolism are being continuously discovered because of advances in genetic testing and bioinformatics. The advent of next generation sequencing has transformed our ability to test for multiple genes and whole exome or whole genome sequencing within days to weeks, enabling rapid and affordable molecular diagnosis for disorders that cannot be directly diagnosed from standard blood tests or liver biopsy. Thus, our diagnostic algorithms for neonatal cholestasis are undergoing transformation, moving genetic sequencing to earlier in the evaluation pathway once biliary atresia, "red flag" disorders and treatable disorders are excluded. Current therapies focus on promoting bile flow, reducing pruritus, ensuring optimal nutrition, and monitoring for complications, without addressing the underlying cause of cholestasis in most instances. Our improved understanding of bile formation and the enterohepatic circulation of bile acids has led to emerging therapies for cholestasis which require appropriate pediatric clinical trials. Despite these advances, the cause and optimal therapy for biliary atresia remain elusive. The goals of this review are to outline the etiologies, diagnostic pathways and current and emerging management strategies for neonatal cholestasis.

Abstract
BACKGROUND Intravenous administration of parenteral nutrition (PN) admixtures containing 4-oil lipid injectable emulsion (ILE) in preterm neonates is usually prohibited because of limited clinical data. The authors evaluated the stability, safety, and efficacy of PN admixtures containing 4-oil ILE, for the first time, in preterm neonates. METHODS A series of PN admixtures were prepared for consecutive administration in preterm neonates over a period of 15 days. Admixture stability was assessed after 24 hours of storage at 25 and 37 °C via visual inspection and measurement of mean droplet size (MDS). Safety and efficacy of the admixtures in preterm neonates were assessed via serum triglyceride levels and body weight increase measurements, respectively. RESULTS PN admixtures were stable at 25 °C and had MDS ˂500 nm. After 15 days, there was a significant increase in body weight (P ≤ .0001) and level of serum triglycerides (P ≤ .0001), compared with the level before PN administration. CONCLUSIONS PN admixtures containing 4-oil ILE were stable at 25 °C and showed instability at 37 °C. Therefore, it is recommended to keep the temperature during administration of PN admixtures at 25 °C. PN admixtures were well tolerated and safe over a period of 8 days while providing a balanced fatty acid supply. Tight monitoring of serum triglyceride level is essential, particularly in neonates of low birth weight and/or young gestational age, to avoid hypertriglyceridemia. Hence, the use of these PN admixtures is expected to be beneficial in terms of being cost-effective and reducing the contamination risks.

Abstract
Background: The reasonable use of amino acids (AAs) in parenteral nutrition (PN) is very critical to the growth and development of premature infants. However, the appropriate dose of AAs has not been determined. Our study was designed to investigate the clinical effect of two different doses of AAs in PN for low birth weight premature infants. Materials and Methods: This randomized controlled study included 191 preterm infants who admitted to the neonatal intensive care unit of the First Affiliated Hospital of Nanjing Medical University from June 2015 to December 2016 and they were randomly divided into Group 1 (n = 81) and Group 2 (n = 110). In Group 1, the starting dose of AAs dose was 1.0–1.5 g/kg/day, which was increased by 0.5 g/kg with the maximum dose at 3.5 g/kg/day. In Group 2, the starting dose of AAs was 1.8–2.5 g/kg/day and was increased by 1.0 g/kg with the maximum dose at 4.0–4.5 g/kg/day. We analyzed the clinical characteristics, body weight, body length, total calorie intake, nonprotein calorie intake, total protein intake, liver and kidney function, and complications of the two groups of preterm infants. Results: The start of enteral feeding and the recovery of birth weight in Group 2 were earlier than those in Group 1 (3.83 ± 3.15 day vs. 5.53 ± 5.63 day, P = 0.016 and 6.36 ± 4.88 day vs. 8.48 ± 9.27 day, P = 0.043, respectively). The duration of PN and the time before total enteral nutrition were shorter in Group 2 than in Group 1 (16.46 ± 10.33 day vs. 21.41 ± 18.00 day, P = 0.029 and 15.47 ± 10.54 day vs. 19.47 ± 14.57 day, P = 0.038; respectively). The duration of mechanical ventilation (1.12 ± 2.62 day vs. 3.31 ± 8.13 day, P = 0.028) in Group 2 was shorter than that in Group 1. Conclusion: High doses of AAs in the early PN for preterm infants facilitate the promotion of early growth and development, advance recovery of birth weight, reduce the duration of PN, and reduce respiratory support without increasing the incidence of complications.

Abstract
BACKGROUND The early diagnosis of biliary atresia (BA) is associated with a better outcome after portoenterostomy. However, very early liver biopsy findings may appear atypical for BA and delay diagnosis. Repeat biopsy histology may change rapidly to show more typical features. METHODS Between 1997 and 2018, 6 babies with jaundice had more than one biopsy to establish diagnosis. Clinical and histologic data were collected. chi-Square was used for analysis (p < 0.05 significant). RESULTS Five patients had two biopsies, and one had three. Median age at first, second, and third biopsy was 40 (13-57), 68.5 (35-78), and 133 days, respectively. Biopsy readings showed no portal edema initially (0/6), but in all 6 on repeat biopsy (p = 0.001). Bile duct proliferation was seen in 6/6 final biopsies, but in only 1/6 initially (p = 0.003). All patients underwent a portoenterostomy (median age 75 days (43-113)). Median delay between initial biopsy and Kasai was 29 days (14-67). Transplant free survival (n = 5 patients) ranged from 184 to 716 days (median 309 days). One patient died before being transplanted. CONCLUSION Early biopsies may not display characteristic findings of BA, but these can appear quickly on subsequent evaluation. The interval needed to repeat a biopsy may have an adverse effect on bile drainage. LEVEL OF EVIDENCE IV.

Abstract
Parenteral nutrition-associated cholestasis (PNAC) causes serious morbidity in the neonatal intensive care unit. Infection with gut-associated bacteria is associated with cholestasis, but the role of intestinal microbiota in PNAC is poorly understood. We examined the composition of stool microbiota from premature twins discordant for PNAC as a strategy to reduce confounding from variables associated with both microbiota and cholestasis. Eighty-four serial stool samples were included from 4 twin sets discordant for PNAC. Random Forests was utilized to determine genera most discriminatory in classifying samples from infants with and without PNAC. In infants with PNAC, we detected a significant increase in the relative abundance of Klebsiella, Veillonella, Enterobacter, and Enterococcus (P < 0.05). Bray-Curtis dissimilarities in infants with PNAC were significantly different (P < 0.05) from infants without PNAC. Our findings warrant further exploration in larger cohorts and experimental models of PNAC to determine if a microbiota signature predicts PNAC, as a basis for future interventions to mitigate liver injury.

Abstract
Very preterm infants (VPI, born at or before 32 weeks of gestation) are at risk of adverse health outcomes, from which they might be partially protected with appropriate postnatal nutrition and growth. Metabolic processes or biochemical markers associated to extrauterine growth restriction (EUGR) have not been identified. We applied untargeted metabolomics to plasma samples of VPI with adequate weight for gestational age at birth and with different growth trajectories (29 well-grown, 22 EUGR) at the time of hospital discharge. A multivariate analysis showed significantly higher levels of amino-acids in well-grown patients. Other metabolites were also identified as statistically significant in the comparison between groups. Relevant differences (with corrections for multiple comparison) were found in levels of glycerophospholipids, sphingolipids and other lipids. Levels of many of the biochemical species decreased progressively as the level of growth restriction increased in severity. In conclusion, an untargeted metabolomic approach uncovered previously unknown differences in the levels of a range of plasma metabolites between well grown and EUGR infants at the time of discharge. Our findings open speculation about pathways involved in growth failure in preterm infants and the long-term relevance of this metabolic differences, as well as helping in the definition of potential biomarkers.

BACKGROUND Premature infants have a high concentration of conjugated bilirubin in their blood, although they have a poor glucuronide conjugation of bilirubin. This may be due to developmental changes in the function of adenosine triphosphate binding cassette subfamily C member 2, which is involved in the cellular export of conjugated bilirubin. In the present study, we examined the developmental changes in the urinary coproporphyrin I/(urinary coproporphyrin I+ urinary coproporphyrin III) ratio (UCP (I/ [I + III])), a known biomarker for adenosine triphosphate binding cassette subfamily C member 2 function, in premature infants. METHOD Twenty-one premature infants born between 25 and 32 weeks of gestation were included in the study. Urine samples were collected within 24 h of birth, and at 1 week and 3-4 weeks after birth. The samples were analyzed by high-performance liquid chromatography to calculate UCP (I/ [I + III]) to examine its association with postnatal age and corrected gestational age. Subjects were excluded if they had liver dysfunction, cholestasis, urinary tract infection, or chromosomal abnormalities. RESULTS The average UCP (I/ [I + III]) within 24 h of birth, at 1 week, and at 3-4 weeks after birth was 0.84, 0.61, and 0.65, respectively. The UCP (I/ [I + III]) within 24 h of birth was significantly higher than that measured at 1 week or 3-4 weeks after birth. There was no significant correlation between UCP (I/ [I + III]) and the corrected gestational age. CONCLUSION The UCP (I/ [I + III]) was higher within 24 h of birth. It decreased 1 week after birth and remained low without any significant changes for up to 4 weeks after birth.

Neonatal Cholestasis Over Time: Changes in Epidemiology and Outcome in a Cohort of 154 Patients From a Portuguese Tertiary Center. Front Pediatr 2020; 8:351. [PMID: 32695736 PMCID: PMC7338938 DOI: 10.3389/fped.2020.00351] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 05/27/2020] [Indexed: 01/23/2023] Open
Abstract
Introduction: In the last two decades there have been advances in the diagnosis and management of neonatal cholestasis, which may have changed its epidemiology, diagnostic accuracy, outcomes, and survival. Our goal was to characterize these changes over time in our setting. Methods: Retrospective cohort study in a tertiary center, enrolling patients born between January 1985 and October 2019. The cohort was divided into two periods, before (A; n = 67) and after (B; n = 87) the year 2000; and in two groups, according to patient's outcome (favorable, unfavorable). Overall survival and survival with and without orthotopic liver transplant (OLT) were evaluated in the two periods (A and B) and in different subgroups of underlying entities. Results: We found that the age of cholestasis recognition decreased significantly from period A to period B [median 43 days and 22 days, respectively, (p < 0.001)]; the changes in epidemiology were relevant, with a significant decrease in alpha-1-antitrypsin deficiency (p < 0.001) and an increase in transient cholestasis (p = 0.004). A next-generation sequencing (NGS) panel available since mid-2017 was applied to 13 patients with contributory results in 7, but, so far, only in 2 patients led to conclusive diagnosis of underlying entities. The number of cases of idiopathic cholestasis did not vary significantly. Over time there was no significant change in the outcome (p = 0.116). Overall survival and survival without OLT had no significant improvement during the period of observation (in periods A and B, 86 vs. 88%, and 85 vs. 87%, respectively). However, in period B, with OLT we achieved the goal of 100% of survival rate. Conclusions: Our data suggest that transient cholestasis became a very important subset of neonatal cholestasis, requiring specific guidance. The NGS panels can provide important inputs on disease diagnosis but, if applied without strict criteria and expertise, they can open a Pandora's box due to misinterpretation. Despite all the advances in accurate diagnosis and timely management-including early recognition of cholestasis-the improvement in patient outcomes and survival were still not significant.

Abstract
BACKGROUND Metabolic bone disease of prematurity (MBD) is a common problem among preterm infants. Our previous study identified cholestasis as an important risk factor for the development of MBD. We conducted this study to determine the vitamin D status in preterm infants with MBD and cholestasis. METHODS We retrospectively reviewed medical record of preterm infants evaluated in NICU at Holtz Children's/Jackson Memorial Hospital between June 2014 and May 2016. Demographic, biochemical data, and vitamin D intake were collected and analyzed. RESULTS We identified 58 preterm infants (median gestational age 25 weeks) with MBD during this period. Twenty five infants also developed cholestasis. Median serum 25-hydroxyvitamin D level at the time of diagnosis of MBD was similar in cholestasis (C), (29.1 ng/ml, IQR 24.4-33.5), and non-cholestasis (NC), (28.7 ng/ml, IQR 22.7-34.6), group (p = 0.41). At the second measurement, average 6 weeks after the first measurement; median serum 25-hydroxyvitamin D level was lower (p = 0.02) in the C group (31.2 ng/ml, IQR 23.0-38.8) than in the NC group (36.5 ng/ml, IQR 28-45). However, the actual percentage of infants with vitamin D deficiency was similar in both the groups. CONCLUSION Most preterm infants with cholestasis and MBD had normal vitamin D status.

Abstract
Neonatal cholestasis is a group of rare disorders of impaired bile flow characterized by conjugated hyperbilirubinaemia in the newborn and young infant. Neonatal cholestasis is never physiological but rather is a sign of hepatobiliary and/or metabolic disorders, some of which might be fatal if not identified and treated rapidly. A step-wise timely evaluation is essential to quickly identify those causes amenable to treatment and to offer accurate prognosis. The aetiology of neonatal cholestasis now includes an expanding group of molecularly defined entities with overlapping clinical presentations. In the past two decades, our understanding of the molecular basis of many of these cholestatic diseases has improved markedly. Simultaneous next-generation sequencing for multiple genes and whole-exome or whole-genome sequencing now enable rapid and affordable molecular diagnosis for many of these disorders that cannot be directly diagnosed from standard blood tests or liver biopsy. Unfortunately, despite these advances, the aetiology and optimal therapeutic approach of the most common of these disorders, biliary atresia, remain unclear. The goals of this Review are to discuss the aetiologies, algorithms for evaluation and current and emerging therapeutic options for neonatal cholestasis.

Abstract
BACKGROUND In an effort to mitigate the major morbidities and mortality associated with extreme prematurity, we have developed an EXTrauterine Environment for Neonatal Development (EXTEND) designed to provide physiologic support of extremely premature infants. OBJECTIVES We have previously shown that long-term, physiologic support of premature fetal lambs is possible with EXTEND, but in this study, we sought to demonstrate bioenergetic equipoise at the tissue level. METHODS Four premature fetal lambs were delivered by hysterotomy at gestational ages (GA) of 105-107 days (term ∼145 days), cannulated via the umbilical vessels, and transitioned to support on EXTEND for 3-4 weeks. Five control fetuses were age-matched to the GA of experimental fetuses at the time of study end (128-134 days GA) and immediately sacrificed after hysterotomy. Mitochondria were isolated from the heart, liver, kidney, and skeletal muscle of fetuses at the time of sacrifice, and oxygen consumption rates (OCRs) were measured. RESULTS There were no differences in basal mitochondrial OCR between EXTEND and control fetuses for heart, kidney, or skeletal muscle. For liver, the basal OCR was higher in EXTEND fetuses compared to controls. There were no differences in physiologic maximal OCR or reserve capacity for any tissue analyzed. CONCLUSIONS Fetal lambs supported by EXTEND demonstrate physiologic mitochondrial function as evidenced by adequate basal and physiologic maximal cellular respiration as well as preserved reserve capacity.

Abstract
BACKGROUND Patients with gastroschisis and prolonged total (or partial) parenteral nutrition (PN) commonly develop direct hyperbilirubinemia (DH). OBJECTIVE To quantify the prevalence and severity of DH in newborns with gastroschisis and characterize the diagnostic work-up for DH in this patient population. DESIGN/METHODS Retrospective chart review of patients born with gastroschisis between 2005 and 2015 for the first 6 months of life. RESULTS 29 patients were identified with gastroschisis. Mean gestational age and birthweight were 36.4 (± 1.8) weeks and 2.5 (± 0.6) kg. 41% were treated with primary reduction versus staged closure. Peak total and direct bilirubin (DB) levels were 10.17 ± 6.21 mg/dL and 5.58 ± 3.94 mg/dL, respectively. 23 patients (79.3%) were diagnosed with DH and 78.2% underwent additional work-up for hyperbilirubinemia consisting of imaging and laboratory studies, none of which revealed a cause for DH other than the presumed PN-associated cholestasis. In all patients, DB began to decline within 1-10 days of initiation of enteral feeds. CONCLUSION(S) DH is common in patients with gastroschisis and is unlikely to be associated with pathology aside from PN. Additional work-up may lead to unnecessary resource utilization. LEVELS OF EVIDENCE Case series with no comparison group, Level IV.

Abstract
OBJECTIVE To analyze safety, tolerance and efficacy of enteral omega-3 fatty acids (FAs) in the resolution of Parenteral Nutrition Associated Cholestasis (PNAC) and postnatal growth among preterm neonates. STUDY DESIGN This is a single center retrospective case-control study of all neonates born less than 32 weeks of gestation and developed PNAC (Direct bilirubin >2 mg/dl). Infants who received enteral omega-3 FAs supplementation (1 g/Kg/d) served as cases and were compared with gestational age, gender and direct bilirubin level matched controls who did not receive enteral omega-3 FAs supplementation. RESULTS A total of 48 infants were analyzed, 24 who received enteral omega-3 fatty acids were matched with 24 controls. The omega-3 FAs and control groups were similar in gestational age (weeks) and birth weight (gram). Overall there were no differences between the two groups in infants' demographics or clinical characteristics including risk factors for the development of PNAC. Infants who received enteral omega-3 FAs had significantly fewer days of cholestasis (p = 0.025) and a higher average daily weight gain (grams/day) (p = 0.011) than their controls. In a linear regression analysis with days of cholestasis as the dependent variable and Ursodeoxycholic acid (UDCA) and Omega-3 FAs as independent variables, enteral omega-3 FAs remained associated with a shorter duration of cholestasis, p < 0.001. CONCLUSION Enteral fish oil is inexpensive, safe & well tolerated in preterm neonates with no contraindications to enteral feeding. Enteral omega-3 FAs are easy to administer and help in rapid resolution of PNAC while promoting postnatal weight gain in preterm infants.

Abstract
Parenteral nutrition-associated cholestasis (PNAC) has been linked to plasma accumulation of phytosterols in infants receiving vegetable-oil-based lipid emulsions (LE). To date, information on the ability of infants with PNAC to metabolize intravenous (IV) phytosterols has been very limited. We characterized plasma phytosterol half-life in very low birth weight (VLBW) preterm infants with PNAC. As part of a prospective cohort study, VLBW infants with PNAC underwent serial blood sample measurements of sitosterol (Sito), campesterol (Camp), and stigmasterol (Stigma). Infants without PNAC served as controls (CTRL, control infants). Thirty-seven PNAC infants and 14 CTRL were studied. On PN day 7 and PN day 14, PNAC infants had higher plasma phytosterol concentrations compared to those of CTRL (p < 0.05). A significant and positive correlation was found between plasma Camp, Stigma, Sito concentrations, and IV phytosterol intake from birth to PN day 7 (p = 0.001, p = 0.001, and p = 0.005, respectively). Stigma concentration was positively correlated with conjugated bilirubin on PN day 7 (p = 0.012). After stopping IV LE, half-lives of Camp, Stigma, and Sito became significantly longer in PNAC infants than in CTRL (Camp: 18.8 ±6.2 vs 11.8 ±3.0 days, p = 0.001; Stigma: 13.8 ±5.8 vs 9.4 ±3.4 days, p = 0.023; Sito: 15.3 ±5.0 vs 9.8 ±3.0 days, p = 0.002). In conclusion, phytosterols increased earlier during PN and were eliminated slowly after stopping IV LE in PNAC infants than in CTRL. The Stigma concentration on PN day 7 could represent an early marker of cholestasis. Our results provide additional evidence on the relationship between IV phytosterols and PNAC.

Abstract
AIM OF STUDY The diagnosis of biliary atresia (BA) remains challenging and delay can lead to significant morbidity with time to surgery a key factor in determining outcome. Prematurity may impact on outcome potentially delaying diagnosis. We sought to assess whether the premature BA infants (PBA) have a delayed time to surgery and as such, worse outcomes? METHODS Review of a single-centre prospectively maintained database. Prematurity was defined as delivery < 37/40 gestation. PBA was compared with date-matched term biliary atresia controls on a 2:1 basis. Primary outcomes were clearance of jaundice (< 20 μmol/L) and native liver survival. A retrospective assessment of liver fibrosis was made on biopsies at diagnosis and at Kasai portoenterostomy (KPE) in both premature and term cohorts. Data are quoted as median (range) unless indicated. A P value of ≤ 0.05 was considered statistically significant. RESULTS 21 (female n = 14, 67%) premature infants with BA were treated in the period Jan. 1988-Dec. 2016 and compared with 41 contemporaneous term BA controls. Median gestation was 33 (29-36) weeks and birth weight 1930 (948-4230)g. Twin pregnancy (n = 10) was the leading cause for prematurity and significantly higher than the controls (48 vs. 0%; P < 0.0001). Maternal co-morbidity was high (n = 10, 48%) including pre-eclampsia (19%) and diabetes (14%). Liver biopsy was performed in 19 (90%) patients (all diagnostic) at a median of 57 (4-266) days. Delayed diagnosis (> 50 days) was seen in n = 13 but not associated with parenteral nutrition use (46 vs. 33%, P = 0.59) or phototherapy (50 vs. 83%, P = 0.19). Both BASM (33 vs. 7.5%; P = 0.01) and duodenal atresia (19 vs. 0%; P = 0.01) were seen more frequently in the PBA cohort. Mean fibrosis scores (Ishak) from diagnostic biopsies were lower in the premature group than the control group (2.71 vs. 3.53, P = 0.043) indicating less fibrosis but this equalized by time of subsequent KPE (P = 0.17). Primary surgery was Kasai portoenterostomy (n = 20) at an older median age than controls (65 vs. 56 days; P = 0.06). Liver transplantation was the primary procedure in one late-presenting child. There was an increased but non-significant clearance of jaundice in the PBA group [n = 12/20 (60%) vs 20/41 (48%); P = 0.23] post-KPE. Native liver survival and true survival were not different (P = 0.58 and 0.23). CONCLUSIONS PBA infants have similar outcomes to term infants, despite delayed diagnosis and higher frequency of the syndromic form. The high incidence of discordant twins supports the theory that epigenetic modifications could contribute to the pathogenesis of BA. LEVEL OF EVIDENCE IIIc Retrospective Matched Cohort Study.
