Family conference Discussed the diagnosis of CMV hepatitis and hepatic failure Acquisition of CMV infection – Patient probably acquired infection via transmission transplacentally from the mother (1-3 mos of pregnancy) Plan – Confirm CMV infection (test mother) – Metabolic work-up: test liver parameters to monitor for prognostication purposes – Liver biopsy – cannot be done yet
Option: – Ultimately, liver transplant – Supportive treatment: Nutrition, Vitamins, UDCA, Spironolactone, Albumin transfusion, Lactulose Goals: – Decrease jaundice – Normalize PT, PTT Prognosis Prevalence Family conference

Treatable cause of acute liver failure in infancy Cytomegalovirus infection Petechiae or purpura (79%), hepatosplenomegaly (74%), jaundice (63%), prematurity and blueberry muffin spots consistent with extramedullary hematopoiesis. Laboratory abnormalities: elevated hepatic transaminase and bilirubin levels (as much as half is conjugated), anemia, and thrombocytopenia. Hyperbilirubinemia persists beyond the period of physiologic jaundice.
Treatable cause of acute liver failure in infancy Cytomegalovirus infection CMV (Patient) IgGPositive IgMPositive CMV (mother) IgGPositive IgM Negative CMV PCR: 298 copies/mL
Treatable cause of acute liver failure in infancy Hepatitis B – Mother and patient: HBsAg negative Galactosemia – newborn screen negative, no diarrhea on exclusive breastfeeding Hereditary fructose intolerance – no intake of fructose yet Congenital syphilis – Both mother and patient are VDRL negative
Treatable cause of acute liver failure in infancy Neuroblastoma – Ultrasound liver normal in size with homogenous parenchymal echopattern, smooth contour, no discrete focal mass lesion, no intrahepatic bile duct dilatation, portal vein normal in caliber, gall bladder partially contracted 2.6 x 0.62 cm, visualized common bile duct 0.26 cm in diameter
Treatable cause of acute liver failure in infancy Hereditary tyrosinemia – urine organic acid, succinylacetate screen negative Mitochondrial defects – serum lactate normal at 11.8 mg/dl (NV ) HIV – Mother negative in her IVF work up
Treatable cause of acute liver failure in infancy Neonatal hemochromatosis – serum ferritin slightly increased at 413 ng/ml (NV – Transferrin saturation 68% (NV 15-55%) – Reticulocyte count normal at 0.006( NV ) – Liver biopsy not done as INR has been >3.5 despite Vitamin K daily. – No active bleeding.
11th Hospital Day SUBJECTIVEOBJECTIVE Afebrile Good appetite and activity No vomiting Sleeps well Good urine output Awake and alert HR 118 RR 44 T 36.5 (+) generalized jaundice and icteric sclerae Clear breath sounds, Soft abdomen (+) splenomegaly (+) hydrocoele, right Full Pulses, (+) clubbing Discharged
Acute Liver Failure probably secondary to Severe Neonatal Hepatitis Hepatic Encephalopathy Final Diagnosis

Galactosemia Most common metabolic cause of liver disease in the neonate. Inherited as an autosomal recessive trait and develops because of the deficiency of galactose-1-phosphate uridyl transferase (GALT). Clinical manifestations: jaundice, hepatosplenomegaly, feeding difficulties and vomiting, hypoglycemia, lethargy, irritability, seizures, cataracts. Delayed diagnosis results in cirrhosis and mental retardation Management consists of substituting a lactose-free formula for breast-feeding or for a standard formula, and, later, a galactose-free diet. Cloherty J. Eichenwald E., Hansen A., Manual of Neonatal Care, 7 th edition
Hereditary Fructose Intolerance deficiency of the enzyme aldolase B asymptomatic until they ingest fructose, sucrose, or sorbitol Clinical manifestations: hypoglycemia, jaundice, hepatomegaly, vomiting, lethargy, irritability, seizures, and abnormal LFTs Management is done by elimination of sucrose, fructose, and sorbitol from the diet Cloherty J. Eichenwald E., Hansen A., Manual of Neonatal Care, 7 th edition
Hereditary Tyrosinemia A low protein diet may be required in the management of tyrosinemia. Recent experience with NTBC has shown to be very effective. The most effective treatment in patients with tyrosinemia type I seems to be full or partial liver transplant.
Hereditary hemochromatosis a common autosomal recessive disorder that results in excessive iron deposition in the liver as well as in extrahepatic sites Also known as neonatal iron storage disease frequently are premature or are small for gestational age features of liver failure with hypoalbuminemia, hypoglycemia, coagulopathy, low fibrinogen, and, frequently, thrombocytopenia and anemia.
Liver dysfunction. Galactosemia is the most common metabolic cause of liver disease in the neonate. Hepatomegaly with hypoglycemia and seizures suggest glycogenosis type I or III, gluconeogenesis defects, or hyperinsulinism. Hereditary fructose intolerance (when there is ingestion of fructose or sucrose, in the neonate usually a soy formula), tyrosinemia type I, neonatal hemochromatosis, and mitochondrial diseases can also present predominantly with liver dysfunction in the neonate. Cholestatic jaundice with failure to thrive is observed primarily in alpha-1-antitrypsin deficiency, Byler disease, and Niemann-Pick disease type C.
