Hemolytic disease of the newborn, also known as hemolytic disease of the fetus and newborn, HDN, HDFN, or erythroblastosis fetalis, [1] [2] is an alloimmune condition that develops in a fetus at or around birth, when the IgG molecules (one of the five main types of antibodies) produced by the mother pass through the placenta.
Biliary atresia requires urgent surgical intervention with intraoperative cholangiography. [4] A hepatoportoenterostomy (HPE) procedure is performed to restore the flow of bile from the liver to small intestine. [12] Neonatal cholestasis caused by alpha-1 antitrypsin deficiency does not have any specific treatment. Instead, children with alpha ...
If the neonatal jaundice is not resolved with simple phototherapy, other causes such as biliary atresia, Progressive familial intrahepatic cholestasis, bile duct paucity, Alagille syndrome, alpha 1-antitrypsin deficiency, and other pediatric liver diseases should be considered. The evaluation for these will include blood work and a variety of ...
The biliary atresia phenotype caused by congenital aflatoxicosis in GST M1 deficient neonates is named Kotb disease. [5] Syndromic biliary atresia (e.g. Biliary Atresia Splenic Malformation (BASM)) has been associated with certain genes (e.g. Polycystic Kidney Disease 1 Like 1 - PKD1L1 [6]), and some infants with isolated biliary atresia may ...
Hemolytic disease of the fetus and newborn (HDN) is a condition where the passage of maternal antibodies results in the hemolysis of fetal/neonatal red cells. The antibodies can be naturally occurring such as anti-A, and anti-B, or immune antibodies developed following a sensitizing event. [ 11 ]
[citation needed] Diagnosis is usually made by investigation of a newborn baby who has developed jaundice during the first week of life. Testing. Coombs - after birth, the newborn will have a direct Coombs test run to confirm antibodies attached to the infant's red blood cells. This test is run from cord blood. [5]
Hemolytic disease of the fetus and newborn (HDN) is a condition where the passage of maternal antibodies results in the hemolysis of fetal/neonatal red cells. The antibodies can be naturally occurring such as anti-A, and anti-B, or immune antibodies developed following a sensitizing event. [ 38 ]
A red cell exchange transfusion is usually given to treat severe hyperbilirubinemia or anemia in babies with hemolytic disease of the newborn. It removes neonatal red cells coated with maternal antibody and reduces the level of bilirubin. A ‘double volume exchange’ (160–200 ml/kg) removes around 90% of neonatal red cells and 50% of bilirubin.
