Neonatal hyperbilirubinemia

INTRODUCTION: Unconjugated hyperbilirubinemia is part of the everyday life of the neonatal period as it reflects the adaptation of the metabolism of bilirubin. The neonatal hyperbilirubinemia usually resolves spontaneously, but it can also be the cause of an acute or chronic encephalopathy known as kernicterus. Regardless of the cause, the goal of therapy is to prevent this neurotoxicity while not causing undue harm. Phototherapy and, if it is unsuccessful, exchange transfusion (ECT) remain the primary treatment modalities used to keep the maximal total serum bilirubin (TSB) below pathologic levels...

BACKGROUND: To investigate the association between late preterm antenatal corticosteroid treatment and outcome in late preterm neonates born to mothers with gestational diabetes mellitus, METHODS: All patients with gestational diabetes mellitus who had a late preterm delivery at Etlik Lady Zübeyde Hospital between 2017 and 2021 were included. Women who met the inclusion criteria and were not given antenatal corticosteroid treatment during current pregnancy before 34 0/7 weeks of gestation were divided into two groups according to whether or not they received late preterm antenatal corticosteroid treatment...

Background Some evidence indicates that maternal analgesia during labor may have adverse effects on neonates due to exposure to specific drugs or the potential effects of analgesia on the course of labor. We assessed the clinical outcome of term neonates born to mothers who received epidural analgesia (E) or systemic analgesia with remifentanil (R) during labor. Methods Data was collected retrospectively over one year. We have evaluated the medical records of 247 full-term neonates; 208 were born to mothers who received E and 39 to mothers who received R...

OBJECTIVES: To determine, among neonates at-risk for hyperbilirubinemia, whether measuring end-tidal carbon monoxide concentration (ETCOc) twice before 48 hours could identify those who would develop hyperbilirubinemia and differentiate hemolytic vs. non-hemolytic causes. METHODS: Prospective study on neonates meeting criteria "at-risk for hyperbilirubinemia." Routine bilirubin measurements and 10-day follow-up were used to categorize neonates as; (1) normal (no hyperbilirubinemia, all bilirubins <95th percentile of Bhutani nomogram), (2) having hemolytic hyperbilirubinemia (bilirubin ≥95th percentile, DAT+, elevated retic, or G6PD+), or (3) having non-hemolytic hyperbilirubinemia...

OBJECTIVES: Jaundice occurs in 60% of full-term and 80% of pre-term newborns. This study compared the effect of phototherapy with and without phenobarbital on icteric newborns. MATERIALS & METHODS: This study is a randomized clinical trial conducted from July until March 2018 at Imam Reza Hospital, Mashhad University of Medical Science, Iran. Full-term and near-term neonates with more than 2000 grams who were hospitalized in the mentioned period for jaundice were entered into the study...

OBJECTIVE: To simulate the outcomes of Boulvain's trial by using magnetic resonance imaging (MRI) for estimated fetal weight (EFW) as a second-line confirmatory imaging. STUDY DESIGN: Data derived from the Boulvain's trial and the study PREMACRO (PREdict MACROsomia) were used to simulate a 1000-patient trial. Boulvain's trial compared induction of labor (IOL) to expectant management in suspected macrosomia, whereas PREMACRO study compared the performance of ultrasound-EFW (US-EFW) and MRI-EFW in the prediction of birthweight...

Hemolytic disease of the fetus and newborn (HDFN) may cause severe cholestasis with direct bilirubin concentrations reaching up to 50 times the upper limit of normal. This case report describes twins whose highest direct bilirubin concentrations were 32.2 mg/dL and 50.2 mg/dL, with no significant signs of hepatic impairment. The index pregnancy was complicated by Rhesus factor immunization with anti-D antibodies present in maternal serum, which caused fetal anemia requiring intrauterine blood transfusions. Complementary tests demonstrated Rhesus D alloimmunization as the sole cause of cholestasis...

This comprehensive review thoroughly examines the historical evolution, physiological foundations, and contemporary advancements in the application of phototherapy for neonatal hyperbilirubinemia. Neonatal hyperbilirubinemia, a common condition resulting from the immature hepatic processes in newborns, poses potential risks, including neurotoxicity, if left untreated. The review traces the historical progression from early recognition of neonatal jaundice to the development of various phototherapy modalities, showcasing the dynamic landscape of neonatal care...

Measurement of transcutaneous bilirubin (TcB) is a non-invasive, widely used technique to estimate serum bilirubin (SB). However, its reliability in multiethnic populations during and after phototherapy is still controversial even in covered skin. The aim of this study was to determine the reliability of TcB in covered (cTcB) and exposed (eTcB) skin during and after phototherapy in a multiethnic population of term and preterm neonates according to Neomar's neonatal skin color scale. Prospective, observational study comparing SB and TcB...

BACKGROUND: The effect of vitamin E supplementation on bilirubin levels in infants was previously explored, but the results were inconclusive. PURPOSE: To examine the effect of vitamin E supplementation on bilirubin levels in term infants in the neonatal intensive care unit (NICU). METHODS: This interventional double-blind randomized clinical trial was conducted in the Sanandaj Besat Hospital NICU. Enrolled newborns were between 37 and 42 weeks and 6 days of gestation and required phototherapy according to American Academy of Pediatrics clinical guidelines...

Noninvoluting congenital hemangioma is an extremely rare congenital anomaly in newborn babies and may complicate life-threatening events, including hemorrhage. We present a very rare case of noninvoluting congenital hemangiomas in an Asian and Afghan six-day-old girl that was detected at birth. The noninvoluting congenital hemangiomas were accompanied by hypovolemic shock, anemia, and prolonged jaundice during the first two weeks of life. These diseases were diagnosed by medical history, physical examination, blood analysis, and doppler ultrasonography of the skin lesions...

INTRODUCTION: Recent evidence suggests that blue-light phototherapy impacts gut microbiota composition in jaundiced newborns, leading to disturbances closely related to the therapy's side effects. As a result, gut microbiota may serve as a potential intervention target to mitigate these side effects. In this study, we aim to examine the effects of AB-GG (Lactobacillus rhamnosus LGG), Bb-12 (Bifidobacterium animalis Bb-12) and M-16V (Bifidobacterium breve M-16V) and their combination on the intestinal microbiota, metabolomics and phototherapy-related side effects in neonates with jaundice...

Newborn hyperbilirubinemia during the first two weeks of life is one of most common problems requiring management decisions by a pediatrician. However, high bilirubin levels in the circulation have been associated with neurologic injury under a variety of conditions encountered in the newborn infant, such as hemolysis. The risk for developing dangerous hyperbilirubinemia is multifactorial and is determined by a complex set of factors related to a newborn infant's genetic capacities as well as intra- and extrauterine exposures...

BACKGROUND: To explore the optimal dosage of heparin in peripheral arteriovenous automatic synchronous exchange transfusion therapy for neonatal hyperbilirubinemia. METHODS: A total of 185 neonates received peripheral arteriovenous synchronous blood exchange transfusion for hyperbilirubinemia were enrolled from pediatric department of the Ganzhou People's Hospital between January 2018 and June 2020, which were randomly divided into four groups. On the basis of exchange transfusion, different dose of heparin was pumping at the bleeding site of artery (A: no heparin; B: 100 U/h heparin; C: 200 U/h heparin; D: 300 U/h heparin)...

BACKGROUND: Gestational diabetes (GDM) is associated with an increased risk of hypertensive disorders of pregnancy (HDP), but there are limited data on fetal growth and neonatal outcomes when both conditions are present. OBJECTIVES: We evaluated the risk of abnormal fetal growth and neonatal morbidity in pregnancies with co-occurrence of GDM and HDP. STUDY DESIGN: In a retrospective study of 47,093 singleton pregnancies, we compared the incidence of appropriate for gestational age birthweight (AGA) in pregnancies affected by GDM alone, HDP alone, or both GDM and HDP (GDM/HDP) to that in pregnancies affected by neither disorder using generalized estimating equations (covariates: maternal age, nulliparity, BMI, insurance type, race, marital status and prenatal care site)...

METHODS: Newborn infants who had a positive direct Coombs test and/or had a history of intrauterine transfusion (IUT) due to Rh hemolytic disease were included...

BACKGROUND: Neonatal hyperbilirubinemia (NHB) is one of the most common diseases in the neonatal period. Without timely diagnosis and treatment, it can lead to long-term complications. In severe cases, it may even result in fatality. The UGT1A1 gene and clinical risk factors play important roles in the development and progression of NHB. METHODS: In this study, we conducted a cohort study and analyzed 3258 newborns from the Jilin Women And Children Health Hospital in northern China, including 372 children with hyperbilirubinemia...

OBJECTIVE: To evaluate the association between intrapartum nitrous oxide use and adverse short-term neonatal outcomes. METHODS: This was a retrospective cohort study of individuals with singleton gestations at 35 or more weeks who attempted labor and delivered at an academic hospital between June 1, 2015, and February 28, 2020. Data were extracted from the electronic medical record using billing and diagnostic codes. Patients were classified based on whether they received no intrapartum analgesia or received nitrous oxide only...

BACKGROUND AND OBJECTIVES: Guidelines for the management of neonatal hyperbilirubinemia have helped to reduce rates of significant hyperbilirubinemia. However, recent evidence suggesting overtreatment and potential harms of phototherapy have informed the American Academy of Pediatrics clinical practice guideline revision and the accompanying increase in phototherapy thresholds. These changes are predicted to safely reduce overuse; however, to date, the exact effect of these guidelines has not been established...
