OBJECTIVE: ABO hemolytic disease occurs among neonates with blood groups A or B delivered to group O women. Extreme neonatal hyperbilirubinemia due to ABO disease has been reported, but its frequency is not well known. We sought to determine the odds of developing severe ABO hemolytic disease in the 13 years since adopting universal bilirubin screening/management in the Intermountain Healthcare system. STUDY DESIGN: We conducted a retrospective analysis of neonates born between 2004 and 2016, defining "severe hemolytic disease" as; (1) total serum bilirubin (TSB) >25 mg/dL, or (2) hospital readmission for jaundice, or (3) bilirubin encephalopathy...

Neurotoxic bilirubin is solely conjugated by UDP-glucuronosyltransferase (UGT) 1A1. Due to an inadequate function of UGT1A1, human neonates develop mild to severe physiological hyperbilirubinemia. Accumulation of bilirubin in the brain leads to the onset of irreversible brain damage called kernicterus. Breastfeeding is one of the most significant factors that increase the risk of developing kernicterus in infants. Why does the most natural way of feeding increase the risk of brain damage or even death? This question leads to the hypothesis that breast milk-induced neonatal hyperbilirubinemia might bring certain benefits to the body...

BACKGROUND: African-American (AA) infants are known to have, overall, lower bilirubin levels than infants of other ethnicities during their birth hospitalization. However, they are known to have a higher incidence of severe hyperbilirubinemia and are over represented in the US Kernicterus Registry. Heme oxygenase-1 (HO) is the rate limiting enzyme in heme metabolism leading to the equimolar production of bilirubin, carbon monoxide (CO) and free iron (Fe). Short (S) (GT)n repeats (<25) in the promoter region of the gene encoding the inducible HO-1 isozyme augment its expression, while long (L) repeats (>33) lead to an attenuation, modulating the production of bilirubin and CO...

A significant proportion of term and preterm infants develop neonatal jaundice. Jaundice in an otherwise healthy term infant is the most common reason for readmission to hospital. Jaundice is caused by an increase in serum bilirubin levels, largely as a result of breakdown of red blood cells. Bilirubin is conveyed in the blood as 'unconjugated' bilirubin, largely bound to albumin. The liver converts bilirubin into a conjugated form which is excreted in the bile. Very high levels of unconjugated bilirubin are neurotoxic...

Neonatal jaundice often occurs in the first week after birth. Early detection of neonatal jaundice can prevent kernicterus as a complication of high levels of bilirubin in neonates. Visual assessment is one of the examinations introduced by Kramer to assess the presence of neonatal jaundice. The purpose of this study was to determine the sensitivity, specificity, and accuracy of Kramer's visual assessment in the examination of neonatal jaundice. This study used cross-sectional design to examine 102 infants, with the sample selected by the convenience sampling method...

Neurotoxic bilirubin is the end product of heme catabolism in mammals. Bilirubin is solely conjugated by UDP-glucuronosyltransferase (UGT) 1A1, which is a membrane-bound enzyme that catalyzes a transfer of glucuronic acid. Due to low function of hepatic and intestinal UGT1A1 during the neonatal period, human neonates develop mild to severe physiological hyperbilirubinemia. The accumulation of bilirubin in the brain leads to the onset of irreversible brain damage, kernicterus. Breastfeeding is one of the most significant factors that increase the risk of developing kernicterus in infants...

Neonatal jaundice or hyperbilirubinemia is a common occurrence in newborns. It can progress to develop kernicterus unless intervention is initiated. Severity and decision for management are usually based on serum bilirubin which needs blood sampling. Transcutaneous bilirubin measurement is a noninvasive technique and correlates closely with serum bilirubin. This Cross sectional study was done in the Department of Neonatology, Bangabandhu Sheikh Mujib Medical University from March 2013 to August 2014 to evaluate the transcutaneous bilirubin in comparison to serum bilirubin...

Challenges in treating severe neonatal jaundice in low and middle-income country settings still exist at many levels. These include: a lack of awareness of causes and prevention by families, communities and even sometimes health care professionals; insufficient, ineffective, high quality affordable diagnostic and therapeutic options; limited availability of rehabilitation provision for kernicterus. Collectively these challenges lead to an unacceptably high global morbidity and mortality from severe neonatal jaundice...

Ornithine transcarbamylase deficiency (OTCD) is an X-linked urea cycle defect associated with severe and usually fatal hyperammonemia. This study describes a patient with early onset lethal OTCD due to a known pathogenic variant (c.298+1G>A), as well as the novel autopsy finding of kernicterus with relatively low blood concentration of unconjugated bilirubin (UCB) (11.55 mg/dL). The patient was a full-term male with a family history of two previous male siblings who died as newborns after acute neurologic deterioration...

Despite its lengthy history the study of benign jaundice, hyperbilirubinemia and kernicterus suffers from a lack of clarity and consistency in the key terms used to describe both the clinical and pathophysiological nature of these conditions. This has led to multiple terms being used to describe similar conditions (i.e. kernicterus and chronic bilirubin encephalopathy) or the same term being used to describe different concepts (i.e. BIND as a descriptor of the signs of bilirubin neurotoxicity, mild kernicterus, or as a scale to assess bilirubin toxicity)...

BACKGROUND: Neonatal hyperbilirubinaemia is a common problem which carries a risk of neurotoxicity. Certain infants who have hyperbilirubinaemia develop bilirubin encephalopathy and kernicterus which may lead to long-term disability. Phototherapy is currently the mainstay of treatment for neonatal hyperbilirubinaemia. Among the adjunctive measures to compliment the effects of phototherapy, fluid supplementation has been proposed to reduce serum bilirubin levels. The mechanism of action proposed includes direct dilutional effects of intravenous (IV) fluids, or enhancement of peristalsis to reduce enterohepatic circulation by oral fluid supplementation...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human erythrocyte enzyme defect, estimated to affect approximately 4 million people worldwide. It is associated with severe neonatal hyperbilirubinemia, which may lead to bilirubin encephalopathy and kernicterus, and with hemolytic crisis. G6PD deficiency is an X-linked enzymopathy affecting hemizygous males, homozygous females, and also a subset of heterozygous females via chromosome X inactivation. We report four cases of female newborns with neonatal hyperbilirubinemia related to a G6PD deficiency and followed by the Centre national de référence en hémobiologie périnatale (CNRHP) from November 2013 to July 2014...

Extreme hyperbilirubinemia and kernicterus, though rare, continue to occur despite the adoption of universal screening. Unless they are known to have glucose-6-phosphate dehydrogenase deficiency, infants who currently develop kernicterus in high resource countries are often otherwise healthy newborns discharged from the well-baby nursery. In this review, we highlight risk factors that increase the risk of a newborn ≥35 weeks gestational age developing severe hyperbilirubinemia, as well as the risk factors that increase the hyperbilirubinemic infant's risk of kernicterus...

BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD) deficiency triggered and low-bilirubin kernicterus persist despite current prevention strategies. OBJECTIVE: Efforts to eradicate bilirubin induced brain injury in these two conditions will require novel approaches to riskassessment and hyperbilirubinemia evaluation. METHOD: In the case of G6PD deficency, a heightenedawareness of populations at risk on who expanded kernicterus preventio strategies can befocused including intensified parental engagement, education and counselling on neonataljaundice...

Introduction: Acute bilirubin encephalopathy (ABE) is associated with long-term sequelae (kernicterus). It continues to be a significant issue in our region of Nigeria, accounting for much morbidity and mortality. Herein we report the outcome of neonates with ABE seen at our centre. Methodology: We established a surveillance of children who had ABE and returned to follow-up from prospective cases of ABE (2012-2014). ABE was diagnosed based on a bilirubin-induced neurologic dysfunction score of ≥ 1...

Crigler-Najjar syndrome is a hereditary unconjugated hyperbilirubinemia. Two forms of the disease are recognized. Type I is more severe and results in kernicterus if left untreated, and Type II is less severe and responds to phenobarbital. While Crigler-Najjar syndrome is thought by many to have normal liver histology, few reports of the liver pathology exist. Herein, we present a 19-year-old patient with Crigler-Najjar who underwent liver transplantation. The liver showed marked canalicular cholestasis with portal and variable, delicate, bridging fibrosis...
