Maheshwari S. Case report of fetal liver cirrhosis due to gestational alloimmune liver disease in a primigravida female, in the northeast region of India. ULTRASOUND (LEEDS, ENGLAND) 2023; 31:52-55.

Abstract
Introduction Fetal liver failure is a major cause of neonatal morbidity and mortality, presenting as acute liver failure and/or congenital cirrhosis. Gestational alloimmune liver disease associated with neonatal haemochromatosis is a rare cause of fetal liver failure. Case report 24-year-old primigravida on Level II ultrasound scan showed intrauterine live fetus, with the fetal liver showing nodular architecture and coarse echotexture. Moderate fetal ascites were present. Scalp oedema was present with minimal bilateral pleural effusion. Suspicious fetal liver cirrhosis was raised, and the patient was counseled for a poor prognosis of pregnancy. Surgical termination of pregnancy was performed at 19 weeks through Cesarean section, and postmortem histopathological examination revealed haemochromatosis, hence gestational alloimmune liver disease was confirmed. Discussion The presence of a nodular echotexture of the liver, with ascites, pleural effusion, and scalp oedema suggested chronic liver injury. Gestational alloimmune liver disease-neonatal haemochromatosis is often diagnosed late and patients are therefore referred late to specialized centers, delaying treatment. Conclusion This case highlights the consequences of late diagnosis and treatment of gestational alloimmune liver disease-neonatal haemochromatosis and emphasizes the importance of a high grade of suspicion of this disease. Level II ultrasound scan should include scanning of the liver, as a part of the protocol. A high grade of suspicion is key for the diagnosis of gestational alloimmune liver disease-neonatal haemochromatosis, and early use of intravenous immunoglobulin should not be postponed to allow longer survival of the native liver.

Abstract
Gestational alloimmune liver disease (GALD) is a rare neonatal disorder with high mortality and morbidity. The patients come to caregivers' attention aged a few hours or days. The disease manifests as acute liver failure with or without siderosis. The differential diagnosis of neonatal acute liver failure (NALF) is broad, including mainly immunologic, infectious, metabolic and toxic disorders. The most common cause, however, is GALD followed by herpes simplex virus (HSV) infection. The best suited pathophysiological paradigm of GALD is that of a maternofetal alloimmune disorder. State of the art treatment combines intravenously administered immunoglobulin (IVIG) with exchange transfusion (ET). We report an infant born at 35 + 2 weeks' gestation in whom GALD had a favorable course, of interest because premature birth in our patient may have exerted protective aspects and lessened morbidity in that intrauterine exposure to maternal complement-fixing antibodies was shortened. The diagnosis of GALD was challenging and difficult. We suggest a modified diagnostic algorithm combining clinical findings with histopathologic findings in liver and lip mucosa and, if available, on abdominal magnetic resonance imaging-study focusing on the liver, spleen, and pancreas. This diagnostic workup must be followed by ET and subsequent administration of IVIG without delay.

Abstract
We describe the case of a newborn with the antenatal onset of hepatic failure, which has been investigated for all etiologies that can cause liver damage: infectious, metabolic, genetic, and immune. The lack of a clear answer regarding the etiology and the response to immunoglobulin therapy led us to the diagnosis of gestational alloimmune liver disease. Gestational alloimunne liver disease is an uncommon and very severe cause of neonatal acute liver failure (NALF). Initially, the therapeutic approach aimed at correcting the effects produced by iron loading, respectively, iron chelators and antioxidants. Since all aspects of this case indicated characteristic features typical for GALD, therapy with intravenous immunoglobulins (IVIG) was introduced. If such therapy alters the prognosis of newborns with GALD, the etiology and pathophysiology remain uncertain. However, in cases regarding severe hepatic failure with the perinatal onset and apparently unknown etiology, immunoglobulin or exchange transfusion therapy should be taken into account even before finalizing all the etiological investigations. The prognosis is uncertain and varies between clinical resolution, chronic hepatitis/cirrhosis, and the need for a hepatic transplant, and overall survival depends on prompt therapeutic intervention.

Abstract
Neonatal cholestasis (NC) starts during the first three months of life and comprises extrahepatic and intrahepatic groups of diseases, some of which have high morbimortality rates if not timely identified and treated. Prolonged jaundice, clay-colored or acholic stools, and choluria in an infant indicate the urgent need to investigate the presence of NC, and thenceforth the differential diagnosis of extra- and intrahepatic causes of NC. The differential diagnosis of NC is a laborious process demanding the accurate exclusion of a wide range of diseases, through the skillful use and interpretation of several diagnostic tests. A wise integration of clinical-laboratory, histopathological, molecular, and genetic evaluations is imperative, employing extensive knowledge about each evaluated disease as well as the pitfalls of each diagnostic test. Here, we review the difficulties involved in correctly diagnosing the cause of cholestasis in an affected infant.

Abstract
Paediatric acute liver failure (PALF) is defined as a biochemical evidence of acute liver injury in a child with no previous history of chronic liver disease characterised by an international normalised ratio (INR) of 1·5 or more unresponsive to vitamin K with encephalopathy, or INR of 2·0 or more with or without encephalopathy. PALF can rapidly progress to multiorgan dysfunction or failure. Although the transplant era has substantially changed the outlook for these patients, transplantation itself is not without risks, including those associated with life-long immunosuppression. Consequently, there has been an increased focus on improving medical management to prioritise bridging of patients to native liver survival, which is possible due to improved understanding of the underlying pathophysiology of multiorgan involvement in PALF. In this Review, we discuss recent advances in the medical management of PALF with an aim of reducing the need for liver transplantation. The Review will focus on the non-specific immune-mediated inflammatory response, extracorporeal support devices, neuromonitoring and neuroprotection, and emerging cellular and novel future therapeutic options.

Abstract
Gestational alloimmune liver disease resulting in neonatal haemochromatosis is a rare but often lethal neonatal and fetal condition and is the leading cause of fetal and neonatal liver injury. Chelation-antioxidant treatment, intravenous immunoglobulin therapy and exchange transfusions, as well as liver transplantation have been used as treatments for the affected newborn at birth. In the reported case, a woman with previous neonatal death at 34 weeks of gestation due to gestational alloimmune liver disease commenced weekly doses of intravenous immunoglobulin (1 mg/kg) from 15 weeks in a subsequent pregnancy. A healthy baby boy was delivered following induction of labour at 36 weeks and 5 days of gestation. Following the same protocol, another healthy baby boy was delivered at 37 weeks of gestation. This case report emphasises the clinical utility of antenatal prophylaxis with intravenous immunoglobulin in women at high risk of recurrent gestational alloimmune liver disease. Gestational alloimmune liver disease (GALD) is a rare but often lethal fetal and neonatal condition. Chelation-antioxidant treatment, intravenous immunoglobulin (IVIg) therapy and exchange transfusions, as well as liver transplantation have been used as treatment. This case report emphasises the clinical utility of antenatal prophylaxis with IVIg in women at high risk of recurrent GALD.

Abstract
The liver is responsible for many processes that maintain human metabolic homeostasis and can be affected by several pediatric systemic diseases. In this manuscript, we explore key pathological findings and imaging features across multiple modalities of a spectrum of congenital, metabolic and autoimmune disorders. Strengthening the radiologists' knowledge regarding potential hepatic manifestations of these systemic diseases will ultimately lead to improved care for pediatric patients.

Abstract
Neonatal hemochromatosis is a rare condition that causes neonatal liver failure, frequently resulting in fetal loss or neonatal death. It is thought that most cases of neonatal hemochromatosis are caused by gestational alloimmune liver disease (GALD), with neonatal hemochromatosis being a phenotype of GALD rather than a disease process. Extrahepatic siderosis in the pancreas, myocardium, thyroid and minor salivary gland is a characteristic feature of neonatal hemochromatosis. There is also sparing of the reticuloendothelial system with no iron deposition in the spleen. Hepatic and extrahepatic siderosis seen in neonatal hemochromatosis is from iron dysregulation secondary to liver damage rather than iron deposition causing the liver damage. The presence of extrahepatic siderosis in the pancreas and thyroid is diagnostic of neonatal hemochromatosis and can be detected noninvasively by multi-echo gradient recalled echo (GRE) T2*-weighted sequence of MRI within hours of birth. This helps to expedite the treatment in the form of intravenous immunoglobulin and exchange transfusion, which improves the survival in these babies. The finding of hepatic siderosis is nonspecific and does not help in the diagnosis of neonatal hemochromatosis because it is seen with other causes of advanced liver disease.

Abstract
Gestational alloimmune liver disease (GALD) is a materno-fetal alloimmune disorder that targets the fetal liver and often causes neonatal liver failure. GALD most commonly presents as neonatal hemochromatosis (NH), which is a severe neonatal liver injury confirmed by extra-hepatic iron accumulation at various sites. With the discovery of the alloimmune mechanism of GALD, exchange transfusion and intravenous immunoglobulin (IVIG) administration are being used as novel treatments. Here, we present a rare case of an 11-day-old female infant who presented with marked hyperbilirubinemia. Laboratory findings showed significantly elevated direct and indirect bilirubin, high ferritin and alpha fetoprotein levels, high transferrin saturation, and severe coagulopathy. Abdominal magnetic resonance imaging revealed markedly reduced T2 signal intensity in the liver and pancreas compared to the spleen, suggesting iron deposition. The infant was diagnosed with NH and successfully treated with exchange transfusion and four doses of IVIG.

Abstract
OBJECTIVE Neonatal acute liver failure (ALF) is a rare disease with high mortality for which no standard age-specific definition exists. To advance the understanding of neonatal ALF, we characterize the etiology, presenting features, treatment, and outcomes in infants within 1 month of life. METHODS We performed a single-center 11-year retrospective chart review of neonates ≤30 days of life with ALF as defined by an INR of ≥2.0. Comparisons were made by etiology and survival with native liver (SNL). Estimated survival was performed using the Kaplan-Meier method. RESULTS Forty-three patients met inclusion criteria for neonatal ALF. Etiologies included viral infection (23%), gestational alloimmune liver disease with neonatal hemochromatosis (GALD-NH) (21%), cardiac-associated ischemia (16%), other ischemia (14%), genetic etiologies (9%), Trisomy 21-associated myelodysplasia (TAM) (7%), hemophagocytic lymphohistiocytosis (HLH) (2%), and not identified (7%). Infants with viral etiologies had the highest alanine aminotransferase (ALT) at presentation (1179 IU/L, interquartile range [IQR] 683-1585 IU/L) in contrast to low levels in GALD-NH (23 IU/L, IQR 18-64 IU/L). Across all etiologies, only 33% were alive at 1 year. Overall median survival was 74 days; 17 days for viral infection and 74 days for GALD-NH. Among laboratory values at presentation, alpha-fetoprotein (AFP) was significantly higher in patients that survived with their native liver (P = 0.04). CONCLUSIONS Overall, outcome for neonatal ALF is poor. Although initial laboratory values can differentiate viral infection or GALD-NH, further studies are needed to identify laboratory parameters that predict SNL by etiology to ultimately improve patient outcomes.

Abstract
Background Neonatal hemochromatosis (NH) is a rare condition that was the main reason for liver transplantation in infants. With the realization that NH results from the fetal complement-mediated liver injury, intravenous immunoglobulins (IVIG) were successfully introduced for the treatment. Case Presentation We present two cases of NH from the same family to illustrate the role of antenatal treatment with IVIG in alleviation and possible prevention of this serious morbidity. Conclusion A prenatal treatment and early postnatal administration of IVIG are effective ways to manage NH that help to reduce the severity of the symptoms, prevent liver failure, and avoid the need for liver transplantation.

Background: Gestational alloimmune liver disease (GALD) is a rare but critical cause of neonatal liver failure. After discovering the maternal-fetal alloimmune mechanism, intravenous immunoglobulin (IVIG) with or without exchange transfusion (ET) has gradually replaced antioxidant cocktails as the first-line therapy. Whether such therapy changes the outcome of neonates with GALD is yet to be defined. Method: We reported a pair of twins with discordant presentations, mild and self-limited in the older, whereas liver failure in the younger, who was successfully rescued by ET and IVIG. To investigate the outcome after therapeutic alteration, 39 cases between 2005 and 2020 from literature research were collected. Results: Half of the collected cases (47.1%) were preterm. Common presentations were ascites, jaundice, respiratory distress, hepatomegaly, and edema. Leading laboratory abnormalities were coagulopathy, hypoalbuminemia, and elevated serum ferritin. Salivary gland biopsy and magnetic resonance imaging detected extrahepatic siderosis in 70% (14/20) and 56% (14/25), respectively. IVIG, ET, and liver transplantation were performed in 19 (48.7%), 15 (38.5%), and 8 (20.5%) patients, respectively. The overall survival (OS) rate and native liver survival (NLS) rate were 64.1% (25/39) and 43.6% (17/39), respectively. Although the compiled results did not support a significant benefit, the OS and NLS were higher in the IVIG with/without ET group compared with those treated with conventional therapy [OS (70 vs. 57.9%) and NLS (55 vs. 31.6%), respectively]. Conclusion: A high index of suspicion for GALD is crucial when facing a neonate with liver failure. Despite no significant influence on the outcome over conventional therapy in such a rare and detrimental disease, IVIG with or without ET can be worth trying before resorting to liver transplantation, which is resource-demanding and technique-challenging in small infants.

Abstract
Intravenous immunoglobulin (IVIG) was first administered to humans in the 1980s. The mechanism of action of IVIG is still a subject of debate but the pharmacokinetics have been well characterized, albeit outside of pregnancy. IVIG has been used in pregnancy to treat several nonobstetrical and obstetrical-related conditions. However, current evidence suggests that IVIG use during pregnancy can be recommended for 1) in utero diagnosis of neonatal alloimmune thrombocytopenia; 2) gestational alloimmune liver disease; 3) hemolytic disease of the fetus and newborn for early-onset severe intrauterine disease; 4) antiphospholipid syndrome (APS) when refractory to or contraindicated to standard treatment, or in catastrophic antiphospholipid syndrome; and 5) immune thrombocytopenia when standard treatment is ineffective or rapid increase of platelet counts is needed. All recommendations are based on case series and cohort studies without randomized trials usually because of the rare prevalence of the conditions, the high incidence of adverse outcomes if left untreated, and ethical concerns. In contrast, IVIG therapy cannot be recommended for recurrent pregnancy loss, and the use of IVIG in subgroups of those with recurrent pregnancy loss requires further investigations. For non-obstetrical-related conditions, we recommend using IVIG as indicated for nonpregnant patients. In conclusion, the use of IVIG during pregnancy is an effective treatment in some obstetrical-related conditions with rare serious maternal side effects. However, the precise mechanisms of action and the long-term immunologic effects on the fetus and neonate are poorly understood and merit further investigations.

Abstract
Intravenous immune globulin (IVIG) is made after processing plasma from healthy donors. It is composed mainly of pooled immunoglobulin and has clinical evidence-based applications in adult and pediatric populations. Recently, several clinical applications have been proposed for managing conditions in the neonatal population, such as hemolytic disease of the newborn, treatment, and prophylaxis for sepsis in high-risk neonates, enterovirus parvovirus and COVID-19 related neonatal infections, fetal and neonatal immune-induced thrombocytopenia, neonatal hemochromatosis, neonatal Kawasaki disease, and some types of immunodeficiency. The dosing, mechanism of action, effectiveness, side effects, and adverse reactions of IVIG have been relatively well studied in adults but are not well described in the neonatal population. This review aims to provide the most recent evidence and consensus guidelines about the use of IVIG in the fetus and neonate.

Abstract
Liver diseases affecting the mother and infant dyad may present in the perinatal period from 20 weeks of gestation to 28 days of life. This review will focus on the current approach to neonatal acute liver failure and the progress made in the diagnosis and management of gestational alloimmune liver disease. It will highlight mother-to-child transmission of viral hepatitis, both management and public health implications. Emerging concepts implicating maternal obesity and nutrition in the development of a rapidly progressive nonalcoholic steatohepatitis phenotype in the offspring will be discussed. Finally, the presentation and management of acute fatty liver of pregnancy and intrahepatic cholestasis of pregnancy, and their impact on the fetus, will be reviewed.

Abstract
OBJECTIVES Exchange transfusion (ET) and intravenous immunoglobulin are potentially life-saving treatment options in newborns with gestational alloimmune liver disease (GALD). Since 2008, early ET has been the standard of care for symptomatic neonates with suspected GALD in our unit. The present study's aim was to investigate the outcomes of this approach. METHODS From 2008 to 2018, all neonates who received ET for suspected GALD were identified, and their clinical course and outcomes were analyzed in a descriptive cohort study. In survivors, liver function parameters before ET and maximum values after ET and at discharge were compared. RESULTS During the 11-year period, 12 infants received ET for suspected GALD at a median (range) chronological age of 11 (1-23) days and gestational age of 38 (32-40) weeks. Signs of impaired liver function, most frequently postnatal hypoglycemia, hyperferritinemia, direct hyperbilirubinemia, and coagulopathy, were present in all infants. Survival without a liver transplant in the overall cohort was 10 of 12 (83.3%) and 7 of 9 (78%) in those fulfilling the criteria of acute liver failure. Two patients died, one of them after liver transplantation. Direct bilirubin typically increased after ET, even in survivors. All survivors recovered and were discharged from the pediatric hepatology outpatient clinic after 8 (3-11) months of follow-up. CONCLUSIONS In newborns with suspected GALD, a limited diagnostic work-up followed by early ET may lead to favorable outcomes. More data are required to develop an evidence-based clinical approach to GALD.

Abstract
Neonatal acute liver failure (NALF) is a rare disease with a few known primary causes: gestational alloimmune liver disease (GALD), viral infections, metabolic diseases, and ischemic injury. Many cases still do not have a known cause. Laboratory evaluation may suggest a diagnosis. Most of the known causes have disease-specific treatments that improve outcomes. Survival is improving with better knowledge about and treatment options for GALD; however, overall mortality for NALF is still 24%. Liver transplant remains an important option for neonates with an indeterminate cause of NALF and those who do not respond to established treatments.

Abstract
Single-ventricle pediatric patients, amongst other children waiting for OHT, are a vulnerable population, especially if candidacy is established before any palliation. NH is a rare disease with poor prognosis in the post-natal period. We present a case of sub-acute NH diagnosed in an infant with HLHS who was listed for OHT while bridged with a pulsatile paracorporeal VAD, with an emphasis on the evolution of the condition throughout the patient's clinical course and the ultimate decision for compassionate deactivation of VAD.

Abstract
Niemann-Pick disease type C (NPC) is a rare autosomal recessive inherited disease characterized by lysosomal accumulation of free cholesterol in macrophages within multiple organs. Infantile-onset NPC often presents with jaundice and hepatosplenomegaly from birth, but these symptoms usually improve during early childhood, and it rarely progresses to liver failure. We report three cases from different hospitals in Japan; the patients developed neonatal-onset NPC, and liver transplantation (LT) was performed as a life-saving procedure. LT was performed at 19 days, 59 days, and 4 months of age, respectively. The last patient was diagnosed with NPC before LT, while the first two patients were diagnosed with neonatal hemochromatosis at LT. In these two patients, the diagnosis of NPC was made more than a year after LT. Even though oral administration of miglustat was started soon after the diagnosis of NPC, all patients showed neurological regression and required artificial respiratory support. All patients survived more than one year after LT; however, one patient died due to tracheal hemorrhage at 4.5 years of age, and another one patient was suspected as recurrence of NPC in liver graft. In conclusion, while LT may be a temporary life-saving measure in patients with neonatal-onset NPC leading to liver failure, the outcome is poor especially due to neurological symptoms. A preoperative diagnosis is thus critical.

Abstract
OBJECTIVES Biliary atresia (BA) is a progressive neonatal fibroinflammatory cholangiopathy. We hypothesized that intravenous immunoglobulin (IVIg) would be safe, feasible, acceptable, and efficacious for the treatment of BA. The primary objective of this study was to establish the feasibility, acceptability, and safety profile of IVIg administration after hepatoportoenterostomy (HPE) in BA. The secondary objective was to determine the treatment efficacy of IVIg based on good bile drainage and survival with the native liver. METHODS A multicenter, prospective, open-labeled, phase I/IIA trial of IVIg was conducted, with 1 g/kg/dose of IVIg infused at 3-5, 30, and 60 days post-HPE, and subjects followed for 360 days post-HPE. Twenty-nine participants completed the study. RESULTS Administration of IVIg infusions was feasible and acceptable in 79%. None of the serious adverse events (SAEs) were directly related to IVIg infusions; however, 90% of participants had an SAE. Compared with a historical placebo-arm group, there was no significant increase in the proportion of IVIg participants with a serum total bilirubin <1.5 mg/dL at 90, 180, or 360 days post-HPE. Survival with the native liver in the IVIg participants showed no significant benefit over the historical placebo arm, with a difference at 360 days of -11.9% (IVIg: 58.6%, placebo: 70.5%; 90% UCB: 2.1%; P > 0.05). CONCLUSIONS Although IVIg infusions in infants with BA post-HPE were feasible, acceptable and safe, there was no trend to lower bilirubin levels or improved 360-day survival with the native liver.

Abstract
Biliary atresia is a progressive fibroinflammatory cholangiopathy of infancy that is associated with activation of innate and adaptive immune responses targeting bile ducts. A recently completed multicenter phase I/IIA trial of intravenous immunoglobulin in biliary atresia did not improve serum total bilirubin levels at 90 days after hepatoportoenterostomy or survival with the native liver at 1 year. A mechanistic aim of this trial was to determine if the peripheral blood immunophenotype was associated with clinical outcomes. Flow cytometry of peripheral blood cell markers (natural killer [NK], macrophage subsets, T‐ and B‐cell subsets, regulatory T cells), neutrophils, and activation markers (clusters of differentiation [CD]38, CD69, CD86, human leukocyte antigen‐DR isotype [HLA‐DR]) was performed on 29 patients with biliary atresia at baseline and at 60, 90, 180, and 360 days after hepatoportoenterostomy. Plasma cytokines and neutrophil products were also measured. Spearman correlations of change of an immune marker from baseline to day 90 with change in serum bilirubin revealed that an increase in total bilirubin correlated with 1) increased percentage of HLA‐DR+CD38+ NK cells and expression of NK cell activation markers CD69 and HLA‐DR, 2) decreased percentage of regulatory T cells, and 3) increased interleukin (IL)‐8 and associated neutrophil products (elastase and neutrophil extracellular traps). Cox modeling revealed that the change from baseline to day 60 of the percentage of HLA‐DR+CD38+ NK cells and plasma IL‐8 levels was associated with an increased risk of transplant or death by day 360. Conclusion: Poor outcomes in biliary atresia correlated with higher peripheral blood NK cells and IL‐8 and lower regulatory T cells. Future studies should include immunotherapies targeting these pathways in order to protect the biliary tree from ongoing damage.

Abstract
We report prenatal imaging features of four cases of neonatal hemochromatosis due to an alloimmune disease. All cases exhibited intra uterine growth restriction (IUGR) without arguments for a vascular etiology, associated with oligohydramnios. Placental hydrops was present in 75% of cases. Splenomegaly was identified in one case. Other causes of NH have been ruled out during diagnostic workup including karyotype, detection of IGFBP-1 to evaluate a premature rupture of membranes, maternal serologic tests. MRI was performed in two cases and showed an atrophic liver associated with a low signal intensity on T2-sequence in one case. Prenatal NH was suspected in this later case and the fetus was successfully treated with two IVIG (intravenous immunoglobulins) perfusions performed during pregnancy followed by exchange transfusion and IVIG after birth. The child is doing well with normal liver function tests after 17 months of follow up. Our aim was to highlight the importance of suggesting NH-GALD when facing IUGR with oligohydramnios, ascites, placental hydrops, splenomegaly on prenatal ultrasound with negative work up for placental vascular pathologies and infectious fetopathies. MRI might be of a good help, showing an atrophic liver but enhancing iron overload in hepatic and extrahepatic tissue is helpful but not constant.

A Learning Collaborative Approach Increases Specificity of Diagnosis of Acute Liver Failure in Pediatric Patients. Clin Gastroenterol Hepatol 2018; 16:1801-1810.e3. [PMID: 29723692 PMCID: PMC6197895 DOI: 10.1016/j.cgh.2018.04.050] [Citation(s) in RCA: 49] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Revised: 04/11/2018] [Accepted: 04/20/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND & AIMS Many pediatric patients with acute liver failure (PALF) do not receive a specific diagnosis (such as herpes simplex virus or Wilson disease or fatty acid oxidation defects)-they are left with an indeterminate diagnosis and are more likely to undergo liver transplantation, which is contraindicated for some disorders. Strategies to facilitate complete diagnostic testing should increase identification of specific liver diseases and might reduce liver transplantation. We investigated whether performing recommended age-specific diagnostic tests (AS-DTs) at the time of hospital admission reduces the percentage PALFs with an indeterminate diagnosis. METHODS We performed a multinational observational cohort study of 658 PALF participants in the United States and Canada, enrolled at 10 medical centers, during 3 study phases from December 1999 through December 2014. A learning collaborative approach was used to implement AS-DT using an electronic medical record admission order set at hospital admission in phase 3 of the study. Data from 10 study sites participating in all 3 phases were compared before (phases 1 and 2) and after (phase 3) diagnostic test recommendations were inserted into electronic medical record order sets. RESULTS The percentage of subjects with an indeterminate diagnosis decreased significantly between phases 1-2 (48.0%) and phase 3 (to 30.8%) (P = .0003). The 21-day cumulative incidence rates for liver transplantation were significantly different among phase 1 (34.6%), phase 2 (31.9%), and phase 3 (20.2%) (P = .030). The 21-day cumulative incidence rates for death did not differ significantly among phase 1 (17.9%), phase 2 (11.9%), and phase 3 (11.3%) (P = .20). CONCLUSIONS In a multinational study of children with acute liver failure, we found that incorporating diagnostic test recommendations into electronic medical record order sets accessed at time of admission reduced the percentage with an indeterminate diagnosis that may have reduced liver transplants without increasing mortality. Widespread use of this approach could significantly enhance care of acute liver failure in children.

Abstract
Acute liver failure (ALF) in neonates is rare. Although the incidence is reported to be rare, neonatal hemochromatosis (NH) has to be considered as one of the causes of neonatal ALF. We present a pair of dichorionic twin who had a diverse clinical presentation of NH. One twin passed away despite medical treatment with exchange transfusion and intravenous immunoglobulin (IVIg), whereas the other twin suffered from only mildly deranged liver function, which normalized spontaneously. Early identification of liver failure and clinical awareness of this disease entity are essential to its timely diagnosis and treatment. Antenatal management using IVIg prevents the recurrence of NH in subsequent pregnancies.

Abstract
Neonatal hemochromatosis (NH) has been defined as neonatal liver disorder accompanied by extrahepatic siderosis, and gestational alloimmune liver disease (GALD) is the main cause of NH. We report an atypical case of NH that may have gone underdiagnosed. A male infant was born at term after an uneventful antenatal period. At 7 h of life, he was noted to be tachypneic. Chest X-ray was normal and capillary blood gas analysis showed severe lactic acidosis. An extended blood test showed elevated levels of tyrosine and methionine that, after excluding an inborn error of metabolism, led to the diagnosis of acute liver failure. Hyperferritinemia and elevated transferrin saturation were suggestive of NH. Extrahepatic siderosis on MRI confirmed the diagnosis of NH, so even though the infant was in good general condition, a dose of intravenous immunoglobulin was administered and double volume exchange transfusion was performed. Treatment of a suspected case of GALD and prevention in subsequent gestations is imperative.

Abstract
OBJECTIVES To evaluate pregnancy outcomes in pedigrees of neonatal hemochromatosis to determine the spectrum of gestational alloimmune liver disease (GALD) in a large cohort. STUDY DESIGN We prospectively collected data from women with a prior offspring with proven neonatal hemochromatosis between 1997 and 2015 and analyzed pregnancy outcomes. RESULTS The pedigrees from 150 women included 350 gestations with outcomes potentially related to GALD. There were 105 live-born infants without liver disease, 157 live-born infants with liver failure, and 88 fetal losses. Fetal loss occurred in 25% of total gestations. Ninety-seven pedigrees contained a single affected offspring, whereas 53 contained multiple affected offspring. Analysis of these 53 pedigrees yielded a per-pregnancy repeat occurrence rate of 95%. Notably, the first poor outcome occurred in the first pregnancy in 60% of pedigrees. Outcomes of the 157 live-born infants with liver failure were poor: 18% survived, 82% died. Of the 134 live-born infants with treatment data, 20 received intravenous immunoglobulin with or without double-volume exchange transfusion of which 9 (45%) survived; 14 infants (10%) received a liver transplant of which 6 (43%) survived. CONCLUSIONS GALD is a significant cause of both fetal loss and neonatal mortality with a high rate of disease recurrence in untreated pregnancies at risk. Poor outcomes related to GALD commonly occur in the first gestation, necessitating a high index of suspicion to diagnose this disorder at first presentation.

Abstract
BACKGROUND There are limited data on utility of magnetic resonance imaging (MRI) in the assessment of suspected neonatal hemochromatosis (NH). OBJECTIVES The aim of the study was to present our experience with utilization of multi-echo sequence MRI technique in the evaluation of NH and to compare MRI findings in infants with and without NH. METHODS MRI performed for suspected NH were retrospectively reviewed to note the presence and severity of iron deposition (ID) in liver, spleen, pancreas, and kidneys on multi-echo sequences. Findings were compared in infants with and without NH. RESULTS Of 20 infants (9 boys and 11 girls; median age of 12.5 days) included in the study, 7 of 20 had NH and 13 of 20 were assigned to the non-NH group. Higher degree of pancreatic ID was seen in the NH group (P = 0.001) with 4 of 7 evaluable pancreas showing moderate-to-severe degree and 1 of 7 showing mild degree of ID whereas none of the 13 infants in non-NH group showed moderate or severe degree of pancreatic ID. Even though the severity of hepatic ID was higher in NH group (P = 0.033), variable severity of hepatic ID was seen in both groups with most infants in both groups showing moderate-to-severe degree of ID. The severity of splenic ID was not particularly associated with any group (P = 0.774) but there was no moderate or severe degree of ID in NH. Renal ID was seen in two infants in non-NH group. CONCLUSIONS A moderate-to-severe degree of pancreatic ID seen on MRI tends to be associated with NH and should be sought to establish a timely diagnosis of NH. Presence and severity of hepatic ID cannot be used for differentiation of NH from other causes of neonatal liver failure.

Abstract
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. The infant underwent intensive phototherapy along with four exchange transfusions (ET) and two courses of intravenous immunoglobulins (IVIG). The clinical goals were to keep total bilirubin values ≤ 20 mg/dL in this premature neonate and to minimize the risk of bilirubin-induced neurologic dysfunction and decompensated liver failure. Abnormal iron studies and later magnetic resonance imaging were suggestive of GALD. Liver functions improved over time with normal neurodevelopmental assessment at 3 years of age. To conclude, in infants with NLF soon after birth, earlier consideration of IVIG/ET in the first few days may be beneficial. Larger multicenter data analyses are required to formulate treatment guidelines and indications for phototherapy, ET, and IVIG in sick neonates with NLF.

Abstract
OBJECTIVES To describe the epidemiological features, clinical characteristics and outcomes of neonates diagnosed with liver failure, as well as determine prognostic factors. METHODS Cohort study conducted at a single tertiary referral and university-affiliated pediatric center. Hospital records of all neonates diagnosed with liver failure between January 2003 and December 2015 were retrospectively reviewed, and data on clinical and laboratory findings, treatment, and outcomes were collected. Survival analysis (Kaplan-Meier) and Cox regression were performed to identify prognostic factors at diagnosis. Liver failure diagnosis was established using the pediatric acute liver failure study group's diagnostic criteria for every patient with coagulopathy and biochemical pattern of liver disease. RESULTS Forty-five patients were included. In our series, most cases were secondary to ischemia (28.9%). Other causes were neonatal hemochromatosis (17.8%), viral infections (13.3%), and inborn errors of metabolism (13.3%). A total 55.6% (25/45) of the patients died (median age: 16 days; range 1-235 days). Alanine aminotransferase (ALT) at diagnosis was associated with higher mortality or the need for liver transplantation on day 21 after diagnosis (P = .006). For every 500 IU/L increase in ALT serum levels, the mortality/liver transplantation rate increased 1.3 times (hazard ratio 95% confidence interval: 1.1-1.6). Although ischemic neonatal acute liver failure presents with higher ALT levels, these cases appear to have better outcomes. Higher international normalized ratio tended to increase mortality/transplantation (hazard ratio 1.02; 95% confidence interval 0.91-1.2). CONCLUSIONS Neonatal liver failure should perhaps be considered in the differential diagnoses of any coagulopathy. ALT and international normalized ratio levels at diagnosis could predict prognosis in the short term. Ischemic liver failure appears to have a better prognosis.

Abstract
BACKGROUND Neonatal hemochromatosis caused by a gestational alloimmune mechanism or gestational alloimmune liver disease (GALD) is a rare perinatal disorder characterized by intra- and extrahepatic iron overload. It is believed to result from complement-mediated liver injury, in which the classical complement pathway is activated by maternal antibody/fetal antigen complexes, leading to hepatocyte lysis by the membrane attack complex C5b9. According to some authors, C5b9 expression in more than 75% of liver parenchyma is specific for GALD. METHODS We conducted a retrospective multicentric immunohistochemical study with anti-C5b9 in GALD cases (n = 25) and non-GALD cases with iron overload (n = 36) and without iron overload (n = 18). RESULTS C5b9 was expressed in 100% of GALD cases but involved more than 75% of the liver parenchyma in only 26% of the cases. C5b9 was detected in 26.75% of the non-GALD cases with more than 75% of positive parenchyma in maternal erythrocytic alloimmunization, herpes and enterovirus hepatitis, bile acid synthetic defect, DGUOK mutation, Gaucher disease, cystic fibrosis, and giant-cell hepatitis with autoimmune hemolytic anemia. CONCLUSION Diagnosis and therapeutic management of GALD cannot only be based on C5b9 expression in liver samples as it is not specific of this disease.

Abstract
Neonatal liver failure (NLF) is a major cause of neonatal morbidity and mortality, presenting as acute liver failure and/or congenital cirrhosis. Many affected patients show antenatal signs of fetal injury. There are several causes of NLF and early diagnosis is mandatory to elucidate the etiology and determine a specific treatment or the best management strategy. Gestational alloimmune liver disease associated with neonatal hemochromatosis (GALD-NH) is a rare but potentially treatable cause of NLF. It should be considered in any neonate with fetal signs of disease and postnatal signs of liver failure with no other identifiable causes. GALD-NH is often diagnosed late and patients are therefore referred late to specialized centers, delaying treatment. This case highlights the consequences of late diagnosis and treatment of GALD-NH and emphasizes the importance of a high grade of suspicion of this disease in order to refer the patient to a specialized center soon enough to perform the appropriate treatment.

Abstract
OBJECTIVE Acute liver failure (ALF) in early infancy is rare and challenging to recognize and manage. We aim to describe the presentation and outcome of infants with ALF according to their final aetiology to elucidate features to facilitate early recognition leading to prompt diagnosis and management. METHODS All infants presenting within 120 days from birth with liver failure were included in a retrospective review over a 19-year period. The aetiology, clinical features, presenting investigations, and outcome were collected. RESULTS Seventy-eight young infants presented with ALF. The aetiology was established in 94% and included metabolic disease (36%), hypoxic-ischaemic (HI) insult (19%), infection (17%), neonatal haemochromatosis (9%), and infiltrative disease (9%). Infections, infiltrative disease, and acute HI insult usually resulted in higher transaminases and international normalized ratio, whereas neonatal haemochromatosis and tyrosinaemia were characterized by lower or near normal transaminases. Overall jaundice was not visible in 24% of infants at presentation. Forty-five (58%) infants were alive at discharge from hospital. Survival at 1 year was 53% and survival with native liver 50%. Later deaths occurred in infants with mitochondrial disease. Six infants received a liver transplant and 4 subsequently died from their underlying disease. CONCLUSION ALF should be considered in any young infant with a coagulopathy as transaminases and/or bilirubin levels can be near normal at presentation. Better intensive care and the judicious use of liver transplantation may have contributed to the improved outcomes for this group compared with previous decades.

Abstract
Pediatric acute liver failure (ALF) is a complex and rapidly progressive syndrome that results from a variety of age-dependent etiologies. It is defined by the acute onset of liver disease with no evidence of chronic liver disease. There must be biochemical or clinical evidence of severe liver dysfunction as defined by an international normalized ratio (INR) ≥2. If hepatic encephalopathy is present, INR should be ≥1.5. Unfortunately, due to the rarity of ALF in pediatric patients, there is a paucity of diagnostic and management algorithms and each patient must have an individualized approach.

Abstract
Neonatal hemochromatosis (NH) is a severe neonatal liver injury that is confirmed by extra-hepatic iron accumulation. Although a recent study described treating NH with exchange transfusions and intravenous immunoglobulin, liver transplantation should be considered for patients with severe liver failure that does not respond to other medical treatment. Herein, we report the case of a two-month-old female infant who presented with persistent ascites and hyperbilirubinemia. Her laboratory findings demonstrated severe coagulopathy, high indirect and direct bilirubin levels, and high ferritin levels. Abdominal magnetic resonance imaging presented low signal intensity in the liver on T2-weighted images, suggesting iron deposition. The infant was diagnosed with NH as a result of the clinical findings and after congenital infection and metabolic diseases were excluded. The infant was successfully treated with a living-donor liver transplantation. Living related liver transplantation should be considered as a treatment option for NH in infants.

Abstract
Neonatal acute liver failure (NALF) is a rare disease about which there is little published data; however, NALF is an extremely important condition as it is distinct from acute liver failure seen in older children and adults. First, unlike acute liver failure in older patients, NALF can be diagnosed in an infant with cirrhosis. This is due to the fetal-neonatal continuum of liver disease, or the principle that neonatal liver failure may be the result of a liver disease that began in utero. Further differences exist in the mechanism of disease, diagnostic principles, and the common etiologies of NALF when compared with pediatric and adult acute liver failure. This review will address many of the distinguishing features of NALF and focus on the most common etiologies of NALF, including gestational alloimmune liver disease (GALD), the most common cause of NALF. Additionally, this review will provide insight into the pathogenesis, diagnosis, and treatment of this rare condition. Liver Transplantation 22 677-685 2016 AASLD.

Abstract
Neonatal acute liver disease is relatively rare, with multiple different aetiologies including congenital infections, metabolic disorders, gestational alloimmune liver disease, haemophagocytic lymphohistiocytosis, and ischaemic injury. We report a case of neonatal liver failure in a preterm, growth-restricted infant, who underwent extensive investigation and was clinically diagnosed with gestational alloimmune liver disease, which was confirmed on post-mortem examination. We then discuss management of neonatal liver failure and gestational alloimmune liver disease, including maternal management in future pregnancies.

Abstract
Neonatal hemochromatosis (NH) is a form of neonatal liver failure caused by maternal-fetal alloimmune injury to hepatocytes. The etiology of neonatal hemochromatosis is not exactly understood. However, according to one theory neonatal hemochromatosis is believed to be an alloimmune disorder causing liver injury in the fetus. In order to diagnose neonatal hemochromatosis there are some criteria that should be taken into account, such as positive family history, high serum ferritin levels, high serum alpha-fetoprotein levels and siderosis demonstrated by histology or with magnetic resonance.We present a case of a monochorionic newborn twin who applied to our hospital with sepsis clinical symptoms like clinics, was diagnosed with NH and immediately treated with antioxidant therapy while the other twin with same clinical symptoms did not respond to therapy and passed away. NH should be considered in the differential diagnosis of cases with sepsis-like clinical symptoms that do not respond to antibiotics; early antioxidant therapy in these cases is lifesaving.

Abstract
Although neonatal hemochromatosis (NH) is a well-known cause of liver failure during the neonatal period and iron deposition in extrahepatic tissues is considered essential in the diagnosis of NH, there is no consensus regarding the pathology or diagnostic criteria of NH. Recent studies of immunohistochemical assays have shown that the C5b-9 complex (the terminal membrane attack complement complex) is strongly expressed in the liver of NH cases, suggesting that a gestational alloimmune mechanism is the cause of liver injury. The patient was a low birthweight primiparous male born at 37 weeks of gestation by vaginal delivery. Blood tests 3 h after birth showed signs of liver failure, including high transferrin saturation, resembling the clinical characteristics of NH. However, magnetic resonance imaging and a lip biopsy showed no obvious iron deposition outside the liver. The patient was refractory to exchange transfusion and immunoglobulin therapy but was successfully treated by liver transplantation. Histologically, the explanted liver showed established cirrhosis, with large amounts of human C5b-9 in the residual hepatocytes, suggesting the alloimmune mechanism of liver injury was the cause of his liver failure. Liver failure caused by a gestational alloimmune mechanism should be considered in patients with antenatal liver failure, even without obvious extrahepatic siderosis.
