Xiang Kong, Yan Kong, Fangyuan Zhang, Tingting Wang, Jin Yan
BACKGROUND: Intrahepatic cholestasis of pregnancy (ICP) is a specific pregnancy-related disorder without standard medical therapies. Ursodeoxycholic acid (UDCA) is the most used medicine, but the efficacy and safety of UDCA remain uncertain. Several meta-analyses had been made to assess the effects of UDCA in ICP. However, the samples were not large enough to convince obstetricians to use UDCA. We conducted a meta-analysis to evaluate the effects and safety of UDCA in patients with ICP, which included only randomized controlled trials (RCTs)...

Most published cases of cytomegalovirus infection in pregnancy relate to congenital abnormalities in neonates infected in early pregnancy, while the mother remains asymptomatic. We describe a diagnostically challenging case of an immunosuppressed woman with scleroderma who developed deranged liver function tests attributed to intrahepatic cholestasis of pregnancy and haemolysis, elevated liver enzymes and low platelets syndrome but was ultimately found to have disseminated cytomegalovirus. Cytomegalovirus can present in a myriad of ways...

Aagenaes syndrome, also called lymphoedema cholestasis syndrome 1 (LSC1), is characterized by neonatal intrahepatic cholestasis, often lessening and becoming intermittent with age and severe chronic lymphoedema, mainly affecting the lower extremities. The condition is autosomal recessively inherited, and the gene is located on chromosome 15q. The locus, LCS1, was mapped to a 6.6 cM region on chromosome 15. Angioid streaks are visible irregular crack-like dehiscences in bruch's membrane that are associated with atrophic degeneration of the overlying retinal pigment epithelium...

Kabuki syndrome (KS) is a rare developmental disorder characterized by multiple congenital malformations, postnatal growth retardation, intellectual disability, and recognizable facial features. It is mainly caused by mutations in either KMT2D or KDM6A. We describe a 14-year-old boy with KS presenting with an unusual combination of bilateral microphthalmia with orbital cystic venous lymphatic malformation and neonatal cholestasis with bile duct paucity, in addition to the typical clinical features of KS. We identified the novel KMT2D mutation c...

In humans, mitochondrial DNA (mtDNA) depletion syndromes are a group of genetically and clinically heterogeneous autosomal recessive disorders that arise as a consequence of defects in mtDNA replication or nucleotide synthesis. Clinical manifestations are variable and include myopathic, encephalomyopathic, neurogastrointestinal or hepatocerebral phenotypes. Through clinical exome sequencing, we identified a homozygous missense variant (c.533C>T; p.Pro178Leu) in mitochondrial transcription factor A (TFAM) segregating in a consanguineous kindred of Colombian-Basque descent in which two siblings presented with IUGR, elevated transaminases, conjugated hyperbilirubinemia and hypoglycemia with progression to liver failure and death in early infancy...

PURPOSE OF REVIEW: Pituitary stalk interruption syndrome (PSIS) is characterized by a thin or absent pituitary stalk, hypoplasia of the adenohypophysis, and ectopic neurohypophysis. PSIS manifestations include a wide spectrum of clinical phenotypes and pituitary hormone deficiencies of variable degree and timing of onset. In this review, recent advances with respect to the cause of PSIS, clinical characteristics leading to earlier diagnosis, and management are outlined. RECENT FINDINGS: Diagnosis of PSIS is often delayed probably because clinical findings such as neonatal hypoglycemia, cholestasis, and/or micropenis as well as decreasing growth velocity are not appropriately and timely validated...

BACKGROUND AND AIMS: Biliary atresia (BA) is a severe neonatal cholestasis disease that is caused by obstruction of extra bile ducts. Liver fibrosis progresses dramatically in BA, and the underlying molecular mechanism is largely unknown. METHODS: Amino acids and biogenic amines were quantified by targeted metabolomic methods in livers of 52 infants with BA and 16 infants with neonatal hepatitis syndrome (NHS). Normal adjacent nontumor liver tissues from 5 hepatoblastoma infants were used as controls...

PURPOSE: Infants with Alagille syndrome (AGS) are occasionally misdiagnosed as biliary atresia and subsequently undergo Kasai operation. The purpose of this study was to investigate the outcome of patients with AGS who had previously received Kasai operation during infancy. METHODS: This retrospective study was conducted at the Department of Pediatrics, Samsung Medical Center. We compared the prognosis and mortality between those who had undergone Kasai operation during infancy (Kasai group) and those who had not (non-Kasai group)...

Biliary atresia (BA) is a severe chronic cholestasis disorder of infants that leads to death if not treated on time. Neonatal hepatitis syndrome (NHS) is another leading cause of neonatal cholestasis confounding the diagnosis of BA. Recent studies indicate that altered bile acid metabolism is closely associated with liver injury and cholestasis. In this study, we systematically measured the bile acid metabolome in plasma of BA, NHS, and healthy controls. Liver bile acids were also measured using biopsy samples from 48 BA and 16 NHS infants undergoing operative cholangiography as well as 5 normal adjacent nontumor liver tissues taken from hepatoblastoma patients as controls...

The association between Down syndrome and congenital portosystemic shunts, most commonly caused by patent ductus venosus, remains relatively unknown. The authors present a girl with Down syndrome with patent ductus venosus, pancreaticobiliary maljunction and paucity of interlobular bile ducts, presenting with neonatal cholestasis and transient abnormal myeloproliferative disorder. To the best of authors' knowledge, no report of the concurrent presence of the above in Down syndrome has been published.
