Four children underwent living related liver transplantation because of Crigler-Najjar syndrome type 1. Three were infants aged 2, 8(1/2), and 15 months, and weighed 5, 8, and 10 kg, respectively. Pretransplantation unconjugated bilirubin concentration was 22 to 30 mg/dL despite 12 to 14 hours of phototherapy daily. Patient 1, the 2-month-old infant, with unconjugated bilirubin concentration of 30 mg/dL, had a high-pitched cry, suggestive of bilirubin encephalopathy; results of neurologic examination were normal. Plasmapheresis and urgent liver transplantation were performed. Patient 4, a 13-year-old girl, had learning difficulties at school and attended a special class. Three patients received left lateral liver segments, and 1 patient received a left lobe. Biliary reconstruction was completed with duct-to-duct anastomosis. Bile leakage developed at the anastomosis in 2 patients, which was treated successfully with cholangioplasty. In all patients, the unconjugated bilirubin concentration normalized by day 1 posttransplantation, and no phototherapy was necessary. After transplantation, the 2-month-old infant with suspected encephalopathy exhibited hypotonia, spasticity of the lower extremities, and lack of head control. He died after vomitus aspiration during sleep at 10 months posttransplantation. The other 3 patients are alive with normal neurodevelopmental milestones. Irreversible brain damage may occur early in the course of Crigler-Najjar syndrome type 1. Urgent treatment including plasmapheresis, exchange transfusion, phototherapy, and liver transplantation may not reverse brain damage. Young infants must be evaluated carefully for subtle signs and symptoms of bilirubin encephalopathy. Liver transplantation is curative if performed before development of neurologic dysfunction.

Crigler-Najjar syndrome type I is an autosomal recessive inherited disease and rarely seen in childhood. Bilirubin neurotoxicity is the morbidity of the disease due to the elevated unconjugated bilirubin levels. Mental retardation, seizures, cognitive dysfunction, oculomotor nerve palsy, ataxia, choreoathetosis, and spasticity may be seen. Due to the high bilirubin levels, alterations in the neurophysiological studies may be detected. In this study, we describe two siblings who were diagnosed with Crigler-Najjar syndrome type I who underwent a successful liver transplantation using a single cadaveric organ, together with their neurophysiological follow-up and review of the literature.

Crigler-Najjar syndrome (CNS) is described as severe infantile, nonhemolytic, unconjugated hyperbilirubinemia and is divided into type I and type II according to the patient's response to phenobarbital treatment. Patients with type I CNS usually require a liver transplant. These patients often have spasticity and dystonia, both of which can be treated with intrathecal baclofen therapy. We present the case of a patient with CNS type I who underwent a liver transplant followed years later by intrathecal baclofen therapy. To our knowledge, this article provides the first report of a patient with CNS being treated for dystonia with an intrathecal baclofen pump. Despite his complicated history, this patient has remained medically stable after both interventions.

Crigler-Najjar Syndrome is an uncommon genetic disorder characterized by the elevation of unconjugated plasmatic bilirubin secondary to deficiency of the enzyme uridine diphosphate glucuronyltransferase (UDP-GT). We report a 19-years-old woman with the syndrome diagnosed during the neonatal period, when she developed a severe jaundice in the first 10 days of life, reaching unconjugated bilirubin levels of 29 mg/dl, with normal liver function tests. After transient response to phototherapy, the patient was referred to a tertiary medical center in which an extensive work up ruled out other etiologies and the diagnosis of type I Crigler-Najjar syndrome was established. Currently, the patient has a mild mental retardation. She is receiving homemade phototherapy 18 h per day with acceptable control of bilirubin levels. Many mutations have been associated with UDP-GT dysfunction resulting in a broad spectrum of the disease. When bilirubin rises above physiological limits, it permeates the hematoencephalic barrier, inducing bilirubin impregnation of basal ganglia with secondary neuronal damage and necrosis. The worst outcome, kernicterus, is characterized by mental retardation, central deafness, ophthalmoplegia, ataxia, athetosis, spasticity, seizures and death. First line therapy includes phototherapy, but definitive therapy is liver transplantation before the occurrence of neurological damage.
