Of the remaining instances, a few are due to sensitization of the mother against one of the other Rh antigens or against an antigen belonging to a different blood group system such as Kell. This still leaves a residue of unexplained cases, and in many of these incompatibility of the major ABO blood groups has been held responsible.

ABO incompatibility is the most common maternal-fetal blood group incompatibility and the most common cause of hemolytic disease of the newborn HDN. ABO incompatibility is more often seen in newborns who have type A blood because of the higher frequency of type A compared to type B in most populations.

Management of Pregnancy with ABO Incompatibility

Coronavirus Guidelines. Visit free Relief Central. Prime PubMed is provided free to individuals by: Unbound Medicine. Rh Incompatibility. The reason for reporting this case is to remind that some microorganisms may cause hemolysis leading to early and severe hyperbilirubinemia by secreting hemolysin in cases; where bilirubin levels cannot be successfully decreased despite effective phototherapy, intravenous immunoglobulin, and even exchange transfusion, or in cases of increased rebound bilirubin although urinary tract infection is associated with increased conjugated bilirubin fraction and prolonged jaundice. Anti-D is the most common cause of hemolytic disease of the newborn HDN in the developing countries even after the introduction of anti-D immunoprophylaxis. Still, ABO incompatibility and other alloantibodies against minor blood group antigens have emerged as significant causes of HDN.

Anti-D antibody is not the common cause of Rh-isoimmunization in Chinese neonatal jaundice. Recent change in national population policy has followed by an increase in Rh-isoimmunization related hemolytic disease of the newborn HDN. Unfortunately, regional status of Rh-HDN is unavailable. To investigate the prevalence of hemolytic disease of the newborn due to Rh-isoimmunization in Hefei City. Status of minor blood group antibody was studied in the corresponding mothers. Totally newborns with HDN admitted during the study period and 2.

Hemolytic disease of the newborn (ABO)

Correspondence Address : Dr. Context: ABO blood group antigens are inherited and specific to an individual. In pregnancy, active immunisation occurs when the foetus is of a different ABO blood group from the mother and may result in neonatal jaundice NNJ. Therefore, monitoring and evaluation of mothers at booking and throughout pregnancy and the postpartum period is important in management. Aim: The aim of this study is to determine the prevalence of neo-maternal ABO blood group incompatibility and to assess any relationship with NNJ among mother-neonate pairs in Nguru, Northeast Nigeria. ABO blood group antigens of both mothers and neonates were determined while direct Coomb's test DCT , full blood counts, reticulocyte counts and bilirubin assays were determined for neonates of ABO-incompatible neo-maternal pairs.

The ABO blood group system is the best known surface antigen system, expressed on a wide variety of human cells. In about a third of all ABO incompatible pregnancies maternal IgG anti-A or IgG anti-B antibodies pass through the placenta to the fetal circulation leading to a weakly positive direct Coombs test for the neonate's blood. The antibodies in ABO HDN cause anemia due to destruction of fetal red blood cells and jaundice due to the rise in blood levels of bilirubin a by-product of hemoglobin break down. If the anemia is severe, it can be treated with a blood transfusion, however this is rarely needed. On the other hand, neonates have underdeveloped livers that are unable to process large amounts of bilirubin and a poorly developed blood-brain barrier that is unable to block bilirubin from entering the brain.

The Rh Factor: How It Can Affect Your Pregnancy

Hemolytic disease of the newborn was first described in the medical literature , when it was diagnosed in one French housewife. In Diamond and colleagues described the mutual relationship of fetal hydrops, jaundice, anemia and erythoblastosis, which was later called fetal erytroblastosis. Immune alloantibodies were detected in vivo by indirect Coombs test ICT with serum mother and O test erythrocytes, by direct Coombs test DCT with erythrocytes of a newborn. Most of immune antibodies appear in mothers with O Rh D: negative blood type. In order to reduce the occurrence of alloimmunization of the mother to erythrocyte antigens of the newborn that can lead to major complications in subsequent pregnancies of Rh D: negative mothers and HDN constant monitoring in order to prevent them is necessary.

The Rh factor is a protein that can be found on the surface of red blood cells.
