BACKGROUND AND OBJECTIVES: Bilirubin is routinely measured in neonates to avoid the irreversible effects of kernicterus. Grossly hemolyzed samples are routinely rejected under the assumption that bilirubin cannot be accurately measured in hemolyzed samples. The objective of this study was to determine the effect of hemolysis on bilirubin measurement in neonates. METHODS: Data included 2-years of paired bilirubin results (n=70) where hemolyzed and non-hemolyzed samples were collected and measured within 6h of each other...

INTRODUCTION: Hemolytic kernicterus, an indirect bilirubin-induced brain dysfunction, is associated with hyper-bilirubinemia in mammalian neonates. In this study, a new model of kernicterus has been developed using intra-peritoneal injections of phenyl hydrazine and subcutaneous injections of sulfisoxazole. These drugs can potentially induce kernicterus in neonatal through changes in hemolysis and hypo-albumin. METHODS: For this purpose, 7-day-old male Wistar rats (n=72; mean weight 11±1g) were used...

The clinical expression of bilirubin-induced neurological dysfunction varies according to severity and location of the disease. Definitions have been proposed to describe different bilirubin-induced neurological dysfunction subtypes. Our objective was to describe the severity and clinico-radiological-neurophysiological correlation in 30 consecutive children with bilirubin-induced neurological dysfunction seen over a period of 5 years. Thirty children exposed to acute neonatal bilirubin encephalopathy were included in the study...

Genetic-based susceptibility to bilirubin neurotoxicity and chronic bilirubin encephalopathy (kernicterus) is still poorly understood. Neonatal jaundice affects 60-80% of newborns, and considerable effort goes into preventing this relatively benign condition from escalating into the development of kernicterus making the incidence of this potentially devastating condition very rare in more developed countries. The current understanding of the genetic background of kernicterus is largely comprised of mutations related to alterations of bilirubin production, elimination, or both...

This article brings the choroid plexus into the context of health and disease. It is remarkable that the choroid plexus, composed by the monolayer of epithelial cells that lie in a highly vascularized stroma, floating within the brain ventricles, gets so little attention in major physiology and medicine text books and in the scientific literature in general. Consider that it is responsible for producing most of the about 150mL of cerebrospinal fluid that fills the brain ventricles and the subarachnoid space and surrounds the spinal cord in the adult human brain, which is renewed approximately 2-3 times daily...

Hyperbilirubinemia occurs frequently in newborns, and in severe cases can progress to kernicterus and permanent developmental disorders. Glucose-6-phosphate dehydrogenase (G6PD) deficiency, one of the most common human enzymopathies, is a major risk factor for hyperbilirubinemia and greatly increases the risk of kernicterus even in the developed world. Therefore, a novel treatment for kernicterus is needed, especially for G6PD-deficient newborns. Oxidative stress is a hallmark of bilirubin toxicity in the brain...

Jon F Watchko
Bilirubin-induced neurotoxicity in preterm neonates remains a clinical concern. Multiple cellular and molecular cascades likely underlie bilirubin-induced neuronal injury, including plasma membrane perturbations, excitotoxicity, neuroinflammation, oxidative stress, and cell cycle arrest. Preterm newborns are particularly vulnerable secondary to central nervous system immaturity and concurrent adverse clinical conditions that may potentiate bilirubin toxicity. Acute bilirubin encephalopathy in preterm neonates may be subtle and manifest primarily as recurrent symptomatic apneic events...

Several clinical guidelines for the management of infants with severe neonatal hyperbilirubinemia recommend immediate exchange transfusion (ET) when the risk or presence of acute bilirubin encephalopathy is established in order to prevent chronic bilirubin encephalopathy or kernicterus. However, the literature is sparse concerning the interval between the time the decision for ET is made and the actual initiation of ET, especially in low- and middle-income countries (LMICs) with significant resource constraints but high rates of ET...

This is the clinical history of a term baby born at home who presents a severe hyperbilirubinémia. The medical monitoring was assessed by a private midwife according to parental choice. On the third day of life, the newborn presented an icterus and was exposed to natural daylight in the familial greenhouse under the midwife recommandations. On that day, no laboratory test precised the bilirubin level. On the fifth day, a blood sampling revealed a very high blood bilirubinémia (31 mg/dl or 527 mmol/L), the baby is refered to our NICU and underwent an exchange transfusion...

Late presentation and ineffective phototherapy account for excessive rates of avoidable exchange transfusions (ETs) in many low- and middle-income countries. Several system-based constraints sometimes limit the ability to provide timely ETs for all infants at risk of kernicterus, thus necessitating a treatment triage to optimize available resources. This article proposes a practical priority-setting model for term and near-term infants requiring ET after the first 48 h of life. The proposed model combines plasma/serum bilirubin estimation, clinical signs of acute bilirubin encephalopathy and neurotoxicity risk factors for predicting the risk of kernicterus based on available evidence in the literature...

BACKGROUND: The enzyme, Glucose-6-phosphate dehydrogenase (G6PD), deficiency leads to impaired production of reduced glutathione and predisposes the red cells to be damaged by oxidative metabolites, causing hemolysis. Deficient neonates may manifest clinically as hyperbilirubinemia or even kernicterus. OBJECTIVE: This study was carried out to detect erythrocyte G6PD deficiency in neonatal hyperbilirubinemia. METHODS AND DESIGN: To determine the frequency and effect of G6PD deficiency, this study was conducted on 202 neonates with indirect hyperbilirubinemia...

Kernicterus is a neurological syndrome associated with indirect bilirubin accumulation and damages to the basal ganglia, cerebellum and brain stem nuclei particularly the cochlear nucleus. To mimic haemolysis in a rat model such that it was similar to what is observed in a preterm human, we injected phenylhydrazine in 7-day-old rats to induce haemolysis and then infused sulfisoxazole into the same rats at day 9 to block bilirubin binding sites in the albumin. We have investigated the effectiveness of human adiposity-derived stem cells as a therapeutic paradigm for perinatal neuronal repair in a kernicterus animal model...

BACKGROUND: Neonatal jaundice is a very frequent condition that occurs in approximately 50-70% of term or near-term (>35 GA) babies in the 1st week of life. In some cases, a high bilirubin blood level can lead to kernicterus. There is no consensus for the management of neonatal jaundice and few countries have published national clinical practice guidelines for the management of neonatal jaundice. The aim of this study was to assess the quality of these guidelines. METHODS: We conducted a systematic review of the literature for national clinical practice guidelines for the management of neonatal jaundice in term or near-term babies...

Computerized tomography (CT) and magnetic resonance (MR) are complementary in the imaging of the labyrinth, the internal auditory canal and the brain in children with sensorineural hearing loss who are being evaluated for cochlear implantation. An accurate anatomical description of the inner ear is essential in the preoperative work up. Computerized tomography visualizes the bony structures, whereas MR can discern soft-tissue components including intra labyrinthine fluid, cerebrospinal fluid (CSF), nerves, and vessels within the IAC...

X-linked ichthyosis (XLI) is an X-linked recessive skin disorder generally restricted to males, which arises from mutations in the steroid sulfatase (STS) gene located on Xp22.3. Crigler-Najjar syndrome (CN-I) is a rare autosomal recessive disease caused by the homozygous or compound heterozygous mutations in the UPD‑glucuronosyltransferase 1 family, polypeptide A1 (UGT1A1) gene on chromosome 2q37. A male patient was referred to the Department of Medical Genetics with of severe icterus and ichthyosis. The patient and his family members underwent genetic tests related to XLI and CN-I...

We describe an infant who was readmitted from home at 14 days of age with jaundice and a history of apnoea and episodes of retrocollis/opisthotonos. He had been only mildly jaundiced on discharge from the maternity clinic at 2 days of age. The total serum bilirubin (TSB) on admission was 542 µmol/L, and the infant was treated intensively with triple phototherapy and exchange transfusion. In contrast to what is recommended in Norwegian national guidelines for management of neonatal jaundice, the parents had apparently neither received oral nor written information about jaundice and its follow-up at the time of discharge from maternity...
