Neonatal liver failure (NLF) is a rare diagnosis but carries with it significant risks of mortality and morbidity. Common etiologies for NLF include metabolic causes, gestational alloimmune liver disease (GALD or neonatal hemochromatosis), and viral infections. We report a case of liver failure in a premature infant with abnormal iron profile within 48 hours of birth. Lack of accepted guidelines for the initial management of severe jaundice with a high direct component in the first week after birth made treatment challenging...

REVIEW
Andrew D Clouston
The inherited diseases causing conjugated hyperbilirubinemia are diverse, with variability in clinical severity, histologic appearance, and time of onset. The liver biopsy appearances can also vary depending on whether the initial presentation is in the neonatal period or later. Although many of the disorders have specific histologic features in fully developed and classic cases, biopsies taken early in the disease course may be nonspecific, showing either cholestatic hepatitis or an obstructive pattern of injury requiring close correlation with the laboratory and clinical findings to reach the correct diagnosis...

To examine the origin of seizures induced by severe neonatal hyperbilirubinemia, The EEG characteristics of seizures were analyzed in newborns with and without severe neonatal hyperbilirubinemia. Fisher's exact test was used to determine the specificity. In total, 931 patients had a total serum bilirubin (TSB) level of 340-425 μmol/L, only 2 of whom had seizures. Compared to patients with hyperbilirubinemia and a TSB level of 340-425 μmol/L, those with a TSB level >425 μmol/L had a significant risk of seizure (OR = 213...

INTRODUCTION: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzymopathy in the human population affecting an estimated 8% of the world population, especially those living in areas of past and present malaria endemicity. Decreased G6PD enzymatic activity is associated with drug-induced hemolysis and increased risk of severe neonatal hyperbilirubinemia leading to brain damage. The G6PD gene is on the X chromosome therefore mutations cause enzymatic deficiency in hemizygote males and homozygote females while the majority of heterozygous females have an intermediate activity (between 30-80% of normal) with a large distribution into the range of deficiency and normality...

BACKGROUND: Some neonates develop idiopathic hyperbilirubinemia (INHB) requiring phototherapy, yet with no identifiable causes. We searched for an association between abnormal thyroid levels after birth and INHB. METHODS: Of 5188 neonates, 1681 (32.4%) were excluded due to one or more risk factors for hyperbilirubinemia. Total thyroxine (TT4) and thyroid stimulating hormone values were sampled routinely at 40-48 hours of age and measured in the National Newborn Screening Program...

Introduction: Severe neonatal hyperbilirubinemia can cause mortality and serious morbidities. When phototherapy fails, neonates with severe hyperbilirubinemia should undergo double volume blood exchange transfusion (BET). As this procedure carries a significant risk of mortality and morbidity, adopting guidelines for the treatment of neonatal hyperbilirubinemia is critical to avoid hyperbilirubinemia toxicity and also the complication of an unindicated procedure. Methods: This study investigated the causes, complications, and trend of BET rate in our unit over a 13-year period...

Hyperbilirubinemia is so common in newborns as to be termed physiological. The most common bacteria involved in early-onset neonatal sepsis are Streptococcus agalactiae, commonly called Group B Streptococcus (GBS). Whilst previous studies show bilirubin has antioxidant properties and is beneficial in endotoxic shock, little thought has been given to whether bilirubin might have antibacterial properties. In this study, we performed a transcriptomic and proteomic assessment of GBS cultured in the presence/absence of bilirubin...

BACKGROUND: The pathogenesis of allergic diseases in childhood may be attributed to influences of early environmental stimuli on fetal and neonatal immune regulation. Neonatal hyperbilirubinemia is common in the Asian population and up to 20% of infants require phototherapy. We examined the hypothesis that phototherapy for neonatal hyperbilirubinemia modulates the infant's risk of developing eczema, rhinitis and wheeze in the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort...

Pyruvate kinase deficiency (PKD) is the most common cause of congenital nonspherocytic chronic hemolytic anemia, and patients normally present with mild to severe anemia, unconjugated hyperbilirubinemia, and splenomegaly. Only a few reports of PKD have documented its association with severe, progressive liver failure. In all those cases, the patients died before liver transplant (LT) or immediately after transplant. We report 2 case patients with liver failure associated with PKD who successfully underwent LT and splenectomy: an infant who presented with neonatal cholestasis and a young adult with a severe form of PKD and having been transfusion dependent during childhood...

Neonatal hyperbilirubinemia (NH) is a common finding in newborn babies in Indonesia. Common and rare variants of UGT1A1 have been known to contribute to NH etiology. This study aims to identify UGT1A1 genetic variation and haplotype associated with NH in Indonesian population. DNA was isolated from 116 cases and 115 controls and a targeted-deep sequencing approach was performed on the promoter, UTRs, and exonic regions of UGT1A1 . Determining association of common variants and haplotype analysis were performed using PLINK and Haploview...

Cholestatic jaundice in the first few weeks of life may herald potentially life-threatening pathology. It is therefore incumbent upon the pediatric practitioner to have a high index of suspicion for severe disease when investigating jaundice in a young infant. This article outlines the epidemiology, pathophysiology, differential diagnosis, and diagnostic workup for both the most common and the most severe causes of cholestasis in the neonatal period.

BACKGROUND: Acute bilirubin encephalopathy (ABE) is an important cause of neonatal morbidity in Nigeria, accounting for 5-14% of neonatal deaths. Most newborns with severe ABE have irreversible damage before receiving treatment emphasizing the need for timely pre-admission monitoring and referral. There is limited evidence that educational interventions targeting mothers and health care providers will reduce delayed care. OBJECTIVE: To provide baseline data on the incidence of ABE and associated pre-admission risk factors in five centers of Nigeria in order to evaluate the effect of subsequent educational interventions on outcome...

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an inherited enzymatic disorder associated with severe neonatal hyperbilirubinemia and acute haemolysis after exposure to certain drugs or infections. The disorder can be diagnosed phenotypically with a fluorescent spot test (FST), which is a simple test that requires training and basic laboratory equipment. This study aimed to assess the diagnostic performances of the FST used on umbilical cord blood by locally-trained staff and to compare test results of the neonates at birth with the results after one month of age...
