Xu S, Zhang P, Ge M, Shan Y, Cheng G. Clinical characteristics and outcomes of acute liver failure in neonates: a retrospective cohort in China. Eur J Pediatr 2024; 183:3211-3218. [PMID: 38689183 PMCID: PMC11263379 DOI: 10.1007/s00431-024-05567-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 03/28/2024] [Accepted: 04/09/2024] [Indexed: 05/02/2024]
Abstract
Neonatal acute liver failure (NALF), as a rare disease with high mortality, has limited relevant literature reports in China. We attempted to analyze a NALF cohort to improve the prognosis of this disease. We included all patients diagnosed with NALF at our institution between 2016 and 2021 and retrospectively reviewed their electronic records. NALF was defined as an INR ≥ 2.0 due to liver disease 28 days after birth. Comparisons were made according to etiology and outcome. The Kaplan-Meier method was used to estimate survival. Fifty-eight patients were included in this study. Etiologies included hypoxic/ischemic injury (29.3%), infection (27.6%), gestational alloimmune liver disease with neonatal hemochromatosis (GALD-NH) (10.3%), inherited metabolic diseases (5.2%), hemophagocytic lymphohistiocytosis (1.7%), other etiologies (12.1%), and unidentified causes (13.8%). Enteroviruses constituted 87.5% of the viral infections, whereas herpes simplex virus accounted for no infections. The median INR was significantly lower in the infection group than in the GALD-NH group (P < 0.05 for multiple comparisons). At the last follow-up, none of the patients had undergone liver transplantation, and the overall mortality rate was 50%. Liver function completely recovered in 31% of the patients, all of whom survived. The overall median survival time was 48 days; 26 days for hypoxic/ischemic injury and 43 days for GALD-NH. The incidence of cholestasis was significantly greater among surviving patients (P = 0.018). Conclusion: Hypoxic/ischemic injury and infection are the predominant etiologies of NALF in China. The overall prognosis of NALF is poor, but its short-term prognosis is determined by the etiology. What is Known: • Neonatal acute liver failure (NALF) is a rare disorder with limited cohort studies, especially in China. • Gestational alloimmune liver disease, viral infections (especially herpes simplex virus), metabolic diseases and ischemic insults are common etiologies of NALF, which are significantly different from other populations. • There are no reliable biochemical markers to predict the outcome of NALF. What is New: • In this first report on a Chinese NALF cohort, we demonstrate that hypoxic/ischemic injury and infection (excluding herpes simplex virus) are the predominant etiologies of NALF. • The overall prognosis of NALF is poor, and its etiology determines the short-term outcome.

Abstract
BACKGROUND Acute fulminant liver failure rarely occurs in the neonatal period. The etiologies include viral infection (15%), metabolic/genetic disease (10%), hematologic disorders (15%), and ischemic injury (5%). Gestational alloimmune liver disease usually manifests as severe neonatal liver failure, with extensive hepatic and extrahepatic iron overload, sparing the reticuloendothelial system. Empty liver failure is a rare cause of liver failure where a patient presents with liver failure in the neonatal period with no hepatocytes in liver biopsy. CASE SUMMARY A 5-week-old male presented with jaundice. Physical examination revealed an alert but deeply icteric infant. Laboratory data demonstrated direct hyperbilirubinemia, a severely deranged coagulation profile, normal transaminase, and normal ammonia. Magnetic resonance imaging of the abdomen was suggestive of perinatal hemochromatosis. Liver biopsy showed histiocytic infiltration with an absence of hepatocytes. No hemosiderin deposition was identified in a buccal mucosa biopsy. CONCLUSION Neonatal liver failure in the absence of hepatocellular regeneration potentially reflects an acquired or inborn defect in the regulation of hepatic regeneration.

Abstract
The prevailing concept is that gestational alloimmune liver disease (GALD) is caused by maternal antibodies targeting a currently unknown antigen on the liver of the fetus. This leads to deposition of complement on the fetal hepatocytes and death of the fetal hepatocytes and extensive liver injury. In many cases, the newborn dies. In subsequent pregnancies early treatment of the woman with intravenous immunoglobulin can be instituted, and the prognosis for the fetus will be excellent. Without treatment the prognosis can be severe. Crucial improvements of diagnosis require identification of the target antigen. For this identification, this work was based on two hypotheses: 1. The GALD antigen is exclusively expressed in the fetal liver during normal fetal life in all pregnancies; 2. The GALD antigen is an alloantigen expressed in the fetal liver with the woman being homozygous for the minor allele and the father being, most frequently, homozygous for the major allele. We used three different experimental approaches to identify the liver target antigen of maternal antibodies from women who had given birth to a baby with the clinical GALD diagnosis: 1. Immunoprecipitation of antigens from either a human liver cell line or human fetal livers by immunoprecipitation with maternal antibodies followed by mass spectrometry analysis of captured antigens; 2. Construction of a cDNA expression library from human fetal liver mRNA and screening about 1.3 million recombinants in Escherichia coli using antibodies from mothers of babies diagnosed with GALD; 3. Exome/genome sequencing of DNA from 26 presumably unrelated women who had previously given birth to a child with GALD with husband controls and supplementary HLA typing. In conclusion, using the three experimental approaches we did not identify the GALD target antigen and the exome/genome sequencing results did not support the hypothesis that the GALD antigen is an alloantigen, but the results do not yield basis for excluding that the antigen is exclusively expressed during fetal life., which is the hypothesis we favor.

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.

Laboratory results include the following: white blood cell count, 21,600/μL (21.6 × 109/L; reference range, 9,000-30,000/μL [9-30 × 109/L]); hemoglobin, 18.2 g/dL (182 g/L; reference range, 14.0-24.0 g/dL [140-240 g/L]); platelet count, 111 × 103/μL (111 × 109/L; reference range, 150-450 × 103/μL [150-450 × 109/L]); blood type, B+; direct antiglobulin test, negative; and reticulocyte count, 4% (reference range, 3%-7%). Comprehensive metabolic panel is significant for hyponatremia, with a sodium level of 132 mEq/L (132 mmol/L; reference range, 135-145 mEq/L [135-145 mmol/L]). Liver enzyme levels are normal (alanine aminotransferase, 41 U/L [0.68 μkat/L]; aspartate aminotransferase, 86 U/L [1.44 μkat/L]), as are total protein (5.4 g/dL [54 g/L]) and albumin (3.0 g/dL [30 g/L]) levels. Repeated bilirubin level is 12.4 mg/dL (212 µmol/L) at 14 hours after birth, with an elevated direct bilirubin level of 2.9 mg/dL (49.6 µmol/L). Direct or conjugated hyperbilirubinemia is defined as a direct bilirubin level greater than 2 mg/dL (34.2 mmol/L) or more than 20% of total bilirubin. γ-Glutamyl transferase level is normal. Coagulation studies show an elevated prothrombin time of 23.4 seconds (reference range, 11-17 seconds), with an international normalized ratio of 2.1 (reference range, 0.9-1.3); activated partial thromboplastin level is 49.5 seconds (reference range, 30-60 seconds). Fibrinogen level is decreased at 70 mg/dL (0.70 g/L) (reference range, 230-450 mg/dL [230-450 g/L]). Lactate level is 24.3 mg/dL (2.7 mmol/L; reference range, 2.0-26.9 mg/dL [0.22-2.98 mmol/L]). Ammonia level is 96.6 µg/dL (69 μmol/L; reference range, 89.6-149.9 µg/dL [64-107 μmol/L]). Cerebrospinal fluid studies are unremarkable. Magnetic resonance imaging (MRI) of the brain and echocardiography are normal. Ultrasonography of the abdomen shows diffuse hepatic echogenicity. Blood and cerebrospinal fluid cultures are negative. Further testing reveals the diagnosis.

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.

Dihydro-stilbene gigantol relieves CCl 4-induced hepatic oxidative stress and inflammation in mice via inhibiting C5b-9 formation in the liver. Acta Pharmacol Sin 2020; 41:1433-1445.

Abstract
In general, anti-inflammatory treatment is considered for multiple liver diseases despite the etiology. But current drugs for alleviating liver inflammation have defects, making it necessary to develop more potent and safer drugs for liver injury. In this study, we screened a series of (dihydro-)stilbene or (dihydro-)phenanthrene derivatives extracted from Pholidota chinensis for their potential biological activities. Among 31 compounds, the dihydro-stilbene gigantol exerted most potent protective effects on human hepatocytes against lithocholic acid toxicity, and exhibited solid antioxidative and anti-inflammatory effect in vitro. In mice with CCl4-induced acute liver injury, pre-administration of gigantol (10, 20, 40 mg· kg-1· d-1, po, for 7 days) dose-dependently decreased serum transaminase levels and improved pathological changes in liver tissues. The elevated lipid peroxidation and inflammatory responses in the livers were also significantly alleviated by gigantol. The pharmacokinetic studies showed that gigantol was highly concentrated in the mouse livers, which consisted with its efficacy in preventing liver injury. Using a label-free quantitative proteomic analysis we revealed that gigantol mainly regulated the immune system process in liver tissues of CCl4-treated mice, and the complement and coagulation cascades was the predominant pathway; gigantol markedly inhibited the expression of complement component C9, which was a key component for the formation of terminal complement complex (TCC) C5b-9. These results were validated by immunohistochemistry (IHC) or real time-PCR. Confocal microscopy analysis showed that gigantol significantly inhibited the vascular deposition of TCC in the liver. In conclusion, we demonstrate for the first time that oral administration of gigantol potently relieves liver oxidative stress and inflammation, possibly via a novel mechanism of inhibiting the C5b-9 formation in the liver.

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
Autopsy reports of 78 stillbirths and early infant deaths (up to age 8 weeks) were reviewed to investigate the prevalence of extrahepatic nonreticuloendothelial siderosis (EHNRS) in the context of neonatal liver failure. Of these, 10 liveborns (12.8%), M:F 3:2, with mean gestational age 37.6 weeks (range: 35-39) and mean age at the time of demise 19.1 days (range: 7-42), showed significant liver injury: infection (n = 7, viral > fungal), congenital malformations (n = 2), and ischemia (n = 1). None had maternal history of gestational alloimmune liver disease (GALD) or previous fetal/neonatal death due to liver failure. Seven of 10 cases (70%) showed EHNRS: pancreas (n = 6), kidneys (n = 4), thyroid and adrenal glands (n = 3), and bronchial glands and heart (n = 2). Iron deposition was most frequent in the pancreas (60%), most diffuse in the kidneys, and seen in at least 2 organs, with pancreas and kidney being the most frequent combination. Hepatic C5b-9 expression was variable (1+ to 4+) except 1 case (100% necrosis). The duration of illness and the mean age at the time of demise tended to be higher in those with EHNRS. In summary, hepatic and EHNRS, with or without C5b-9 expression, are not specific for GALD. Other causes of liver failure should be investigated as clinically and pathologically appropriate.

Abstract
Gestational alloimmune liver disease (GALD) is initiated by maternal antibodies that attack fetal hepatocytes. The fetal immune response to the antibodies causes liver damage. The incidence of GALD is four per 100,000 live births in the United States. Frequently, liver injury leads to fetal loss or neonatal demise; nonetheless, the presentation of GALD has a wide range of severity. Survival rates have increased from 20 to 80 percent changes in treatment and understanding of GALD. Current treatment is focused on supportive care with intravenous immunoglobulin (IVIG) and exchange transfusions. Mortality risk is positively associated with the timing of diagnosis. Although there has been an increase in understanding this disease, the discovery of the specific alloantigen is still needed. Relevant embryology, pathophysiology, clinical manifestations, diagnosis, medical treatment, and prognosis are discussed to aid health care professionals in the early identification and treatment for the neonate and family unit.

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.

Neonatal Liver Failure and Congenital Cirrhosis due to Gestational Alloimmune Liver Disease: A Case Report and Literature Review. Case Rep Pediatr 2017; 2017:7432859.

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
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
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.

Abstract
OBJECTIVE Deficiency of Δ(4) -3-oxosteroid 5β-reductase (5β-reductase), a bile acid synthesis disorder, presents findings of neonatal cholestasis and hyper-3-oxo-Δ(4) bile aciduria. The 5β-reductase enzyme participates in not only bile acid synthesis but also hepatic steroid metabolism. Deficiency of 5β-reductase includes 2 types: primary deficiency, with an SRD5B1 gene mutation; and secondary deficiency, lacking a mutation. Secondary deficiency is caused by fulminant liver failure from various aetiologies including neonatal hemochromatosis (NH). Distinguishing primary from secondary deficiency based on γ-glutamyltransferase (GGT), serum total bile acids (TBA), and urinary bile acid analysis using gas chromatography-mass spectroscopy (GC-MS) is very difficult. SRD5B1 gene analysis is the only reliable method. We examined urinary steroid analysis as a way to distinguish primary from secondary 5β-reductase deficiency. DESIGN, PATIENTS AND MEASUREMENTS We examined 12 patients with cholestatic jaundice, normal or slightly elevated GGT, and hyper-3-oxo-Δ(4) bile aciduria using urinary steroid analysis by GC-MS of both cortisol and cortisone compounds, such as 5β-tetrahydrocortisol (5β-THF) and 5β-tetrahydrocortisone (5β-THE). Patients previously were diagnosed with primary 5β-reductase deficiency (n = 3), deficiency secondary to NH (n = 3) and deficiency secondary to other liver disorders (n = 6). RESULTS Urinary steroid analysis in 3 primary deficiency and 3 NH patients showed low 5β-THE and elevated 5α/5β-THE ratios, making distinction difficult without also considering the clinical course and abdominal magnetic resonance imaging (MRI) findings, such as a very low signal intensity in liver and/or pancreas, especially in T2 -weighted images. In the six patients with other secondary deficiencies, urinary 5β-THF and 5α/5β-THF differed from those in primary deficiency (P < 0·05). CONCLUSIONS Urinary steroid analysis can distinguish primary and NH-related deficiencies from other secondary deficiencies.

Abstract
OBJECTIVE To define an algorithm to improve diagnosis of neonatal hemochromatosis (NH) related to gestational alloimmune liver disease (GALD), which is diagnosed by immunohistochemistry demonstrating activated complement at hepatocytes (IDACH). STUDY DESIGN We assessed 56 instances of fetal death or neonatal liver failure (NLF; 2006-2009), 29 (7 stillborns, 22 NLF) with NH, and 27 (5 stillborns, 22 NLF) without NH (non-NH). Immunohistochemistry was retrospectively performed in 21 cases. Cases were grouped as follows: (1) GALD as demonstrated by IDACH (n = 17); (2) indeterminate for GALD (n = 28); or (3) alternate diagnosis found (n = 11). We compared cases of immunohistochemically proven GALD with those with an alternate diagnosis. RESULTS Of the 12 stillborns, 7 had NH because of GALD (NH-GALD), one was undeterminate, and 4 had alternate diagnoses (GALD excluded). Of the 22 newborns with NH, 6 had NH-GALD, one had mitochondrial respiratory chain disorder (MRCD), and 15 were indeterminate for GALD. Of 22 non-NH newborns, extrahepatic siderosis (EHS) was not assessed in 13 (3 GALD, 1 alternate diagnosis [MRCD] and 9 indeterminate GALD) and excluded in 9 (5 alternate diagnoses and 4 indeterminate GALD). The only clinical features found to be associated with GALD were intrafamilial recurrence, prematurity, and EHS. CONCLUSIONS In unexplained fetal death or NLF, the diagnosis of subsets of NH requires tissue analysis (autopsy) to assess EHS. In patients with NH, if MRCD is ruled out, NH-GALD is likely. The rate of IDACH in the diagnosis of GALD in cases without NH requires further study.

Abstract
OBJECTIVES Neonatal haemochromatosis is a rare gestational disease that results in severe foetal liver disease with extrahepatic iron overload, sparing the reticuloendothelial system. Recurrence can be prevented with intravenous immunoglobulin (IVIG) infusions during pregnancy, supporting an alloimmune aetiology. The aim of the study was to assess the effect of antenatal treatment with IVIG infusion on the outcome of pregnancies in women with a history of documented neonatal haemochromatosis likely owing to gestational alloimmune disease and to analyse IVIG tolerance. METHODS From 2004 to 2012, 8 pregnant women were treated with IVIG at 1 g/kg body weight weekly from 18 weeks' gestation until birth in a prospective multicentre study. RESULTS All 8 neonates born to the treated women survived. Five developed mild neonatal liver disease with hepatomegaly (n = 1), hyperechogenic liver (n = 2), abnormal liver function tests (n = 1), raised serum ferritin (n = 3) and α-fetoprotein (n = 5) levels, or mild iron overload on liver magnetic resonance imaging (n = 1). Ferritin and α-fetoprotein levels normalised before 14 days and 2 months, respectively. A per-mother-basis analysis comparing outcomes of treated (n = 8) and untreated (n = 9) gestations showed a significant improvement in the survival of neonates with gestational IVIG therapy (survival 8/8 vs 0/9, P < 0.001). Adverse effects of IVIG infusion occurred in 5 mothers leading to discontinuation of treatment in 1 case. Preterm neonates born before 37 weeks' gestation had a decreased risk of neonatal liver disease (P = 0.04). CONCLUSIONS Antenatal treatment with IVIG infusion in women at risk for gestational alloimmune disease recurrence improves the outcome of pregnancies despite mild signs of transient neonatal liver disease.
