Neonatal jaundice and immunoglobulin

A term baby presented with cholestatic jaundice since birth. She was diagnosed as gestational alloimmune liver disease-neonatal haemochromatosis (GALD-NH) on evaluation. The baby received intravenous immunoglobulin (IVIG) and recovered gradually from the illness. She was also diagnosed with alpha thalassaemia during the course of evaluation, confirmed by genetic testing. NH is a very rare disorder that results in fetal loss or neonatal death due to liver failure. NH is now known to be a phenotypic expression of GALD...

INTRODUCTION: Raised serum bilirubin levels can cause kernicterus, and premature infants are at increased risk owing to metabolic immaturity. The standard treatment for neonatal jaundice is phototherapy, but probiotics alone can reduce the duration of phototherapy and hospitalisation. OBJECTIVES: To determine the effectiveness of phototherapy with and without probiotics for the treatment of indirect hyperbilirubinaemia in preterm neonates. PATIENTS AND METHODS: The open-labelled randomised controlled trial was conducted from January 2022 to January 2023 in the neonatal unit of the University of Lahore Teaching Hospital, Pakistan...

The patient was a male infant, born full-term, admitted to the hospital at 28 days of age due to jaundice for 20 days and abdominal distension for 15 days. The patient developed symptoms of jaundice, hepatosplenomegaly, massive ascites, and progressively worsening liver function leading to liver failure, severe coagulation disorders, and thrombocytopenia one week after birth. Various treatments were administered, including anti-infection therapy, fluid restriction, use of diuretics, use of hepatoprotective and choleretic agents, intermittent paracentesis, blood exchange, and intravenous immunoglobulin, albumin, and plasma transfusions...

BACKGROUND: Use of Direct Antiglobulin test (DAT) in management of neonatal hyperbilirubinemia is conflicting. OBJECTIVE: whether strength of positive DAT predicts the need for phototherapy, duration of phototherapy and need for major interventions. METHODS: We retrospectively collected data on all DAT positive neonates with birth gestational age ≥32 weeks over six years (2014-2019). Data regarding blood group, DAT and clinical details were obtained from a hospital database...

BACKGROUND: Intravenous immunoglobulin G (IVIG) is used to treat blood-type incompatibility hemolytic disease of newborns (BTHDN). Although IVIG's efficacy for treating BTHDN has been challenged, as an updated systematic review suggests, IVIG could significantly reduce exchange transfusions. We conducted a mail-in questionnaire survey to ascertain actual use of IVIG for BTHDN in Japan. METHODS: The survey, conducted in 2014, included infants born between January 1, 2009, and December 31, 2013...

BACKGROUND: One of the most prevalent illnesses in neonates that needs care and treatment is neonatal jaundice. Several drugs are used as pharmacological modalities for treating hyperbilirubinemia, like intravenous immunoglobulin, D-penicillamine, metalloporphyrin, phenobarbital, zinc sulfate and clofibrate. Previous studies suggest the usefulness of fenofibrate in the treatment of hyperbilirubinemia. OBJECTIVES: The study aims at assessing the effectiveness of oral fenofibrate in the treatment of indirect neonatal hyperbilirubinemia in full-term neonates...

Neonatal alloimmune thrombocytopenia (NAIT) is a condition in which maternal IgG antibodies are directed against fetal platelets and cross the placenta, destroying fetal thrombocytes. It is typically caused by maternal alloimmunization to human leukocyte antigens (HLA). ABO incompatibility, on the other hand, is a rare cause of NAIT due to the variable expression of ABO antigens on platelets. Here, we present the case of a first-time mother (O+) who delivered a 37-week 0-day gestation newborn (B+) that was anemic and jaundiced with critically high total bilirubin levels...

Neonatal haemolytic disease in the new-born remains of prime importance for paediatricians due to high perinatal morbidity and mortality rates. The Rh antigen family comprises several different antigens, out of which, D antigen incompatibility is well known for causing severe haemolytic disease in the foetus. Although the current literature shows anomalous cases where coexisting non-D-Rh and D-Rh antigens are the causative agents, there is very little information regarding post-natal outcomes in neonates bearing two different incompatibilities simultaneously...

Dia is a low-frequency member of the Diego blood group system, which is comprised of 23 antigens. The Diego blood group antigens are found on the erythroid membrane glycoprotein band 3, the red cell anion exchanger (AE1). The behavior of anti-Dia in pregnancy can only be surmised by rare, published case reports. This is a case report of severe hemolytic disease of the newborn due to a high-titer maternal anti-Dia immune response. The neonate's mother was monitored throughout pregnancy with Dia antibody titers...

BACKGROUND AND OBJECTIVES: Haemolytic disease of the newborn (HDN) is an immune haemolytic anaemia from maternal alloantibodies. Rh immunoglobulin (RhIg) prophylaxis can prevent alloimmunization to the D antigen. However, RhIg is not universally available in Uganda. ABO incompatibility also causes HDN. We determined the prevalence of HDN among newborn infants with jaundice in Uganda. MATERIALS AND METHODS: We conducted a prospective cross-sectional study at Kawempe National Referral Hospital, Kampala, Uganda...

BACKGROUND: ABO blood group incompatibility, neonatal sepsis, G-6-PD deficiency, thyroid dysfunction, and hereditary spherocytosis are all probable causes of neonatal hyperbilirubinemia. However, the etiology of some hyperbilirubinemia is extremely complicated, which may be caused by multiple factors, resulting in severe jaundice. We report a case of severe jaundice due to three causes, showing the significance for the investigation of the etiology of neonatal hyperbilirubinemia. CASE PRESENTATION: At 96 h of life, a full-term and vaginal delivery male infant with yellowish discoloration of body was transferred to our hospital...

BACKGROUND: Alloimmune hemolytic disease of the newborn (AIHDN) results in hemolysis, anemia, hyperbilirubinemia with the potential for brain damage. Intravenous immunoglobulin (IVIG) has been investigated as an alternative low-risk procedure for the treatment of AIHDN in addition to traditional treatment methods such as phototherapy and exchange transfusion (ET). AIM: To evaluate the effectiveness of IVIG therapy in decreasing ET needs based on risk factors and clinical outcomes...

To study the prevalence of direct antiglobulin test (DAT) positivity and outcomes in babies with ABO incompatibility and the role of DAT in predicting need for phototherapy. This was an analytical retrospective cohort study conducted in a tertiary care hospital in South India. DAT was performed routinely in cord blood of all neonates born to O positive mothers. The case records of neonates ≥ 35 weeks of gestation and birth weight > 2000 gm with ABO setting born between January 2019 and December 2020 were reviewed and outcomes were analyzed...

Introduction: SARS-CoV-2 infection during pregnancy and its impact on the newborn were, in the first months of the pandemic, unknown. Recent studies have provided information on the clinical involvement in the newborn and its evolution.This work shows how passive immunity varies in the newborn in relation to the moment of maternal SARS-CoV-2 infection during pregnancy. Population and method: Observational, prospective and longitudinal study in a third level hospital...

INTRODUCTION: Intravenous immunoglobulin (IVIG) has been widely used to treat the hemolytic disease of the newborn (HDN). Although it has been shown that IVIG treatment reduces the duration of phototherapy and hospitalization, the use of IVIG in hemolytic disease due to ABO incompatibility has been controversial in recent years. This study aimed to investigate the role of IVIG in the prevention of exchange transfusion in infants with ABO HDN who presented with bilirubin levels at or above the level of exchange transfusion...

Introduction Central congenital hypothyroidism (CCH) is a rare disorder that can be caused by X-linked mutations in the immunoglobulin superfamily member 1 (IGSF1) gene. Here, we describe four familial cases with a variable presentation due to a novel IGSF1 pathogenic variant. Case presentation In the index case, investigation at birth of suspected brain-lung-thyroid syndrome surprisingly revealed a central hypothyroidism. Next-generation sequencing (NGS) uncovered a novel IGSF1 pathogenic variant: a hemizygous single base duplication (G) resulting in a premature stop codon (NM_001555...

AIM: Social distancing guidelines implemented with the COVID-19 pandemic impacted health-care utilisation and disrupted critical social supports. Resurgence of highly transmissible strains has resulted in revisiting restrictions with potential impacts on newborn health. With concerns for inadequate post-partum support, we sought to determine if social distancing correlated with increased rates of readmission for hyperbilirubinaemia. METHODS: Retrospective chart review identified all readmissions for hyperbilirubinaemia between 1/18 and 4/20 in Western New York...

BACKGROUND: Neonatal jaundice occurs in more than 80% of newborn infants. Although mild jaundice is physiologic and possibly neuroprotective, severe hyperbilirubinemia can lead to neurologic dysfunction and death. Hyperbilirubinemia is due to an imbalance between bilirubin production and the developing excretory capacity in the first days of life. Management utilizes total serum bilirubin (TSB) levels, although recent advances suggest a role for unbound bilirubin. GOALS: The goal of this review is to examine bilirubin biology, toxicology, and clinical effects, discuss preventive and therapeutic measures, describe neurodevelopmental consequences, and propose that, with the advent of new technology, unbound bilirubin is the optimal measurement for the management...

Viral hepatitis in pregnancy may be caused by many types of viruses that cause systemic infection or target hepatocytes in their pathogenesis. Because viral hepatitis during pregnancy may represent acute or chronic infection or the reactivation of a prior infection, a high clinical suspicion, medical history review, and awareness of risk factors for the acquisition of infection are important management principles. The route of infection varies widely and ranges from fecal-oral transmission for the hepatitis A and E viruses to vertical transmission for hepatitis B, blood-borne transmission for hepatitis C, and sexual transmission for the herpes simplex virus...

BACKGROUND: Hyperbilirubinemia is one of the most common diagnosis in newborn nurseries in United States. Universal pre-discharge bilirubin screening decreased the incidence of extreme hyperbilirubinemia and risk of kernicterus. OBJECTIVES: We sought to assess temporal population trends of hyperbilirubinemia, kernicterus and usage of phototherapy, intravenous immunoglobulin (IVIG), and exchange transfusion. DESIGN/METHODS: Data from Healthcare Cost and Utilization Project (HCUP)-the Kids' Inpatient Database (KID) obtained for years 1997-2012...
