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.


ABO incompatibility is one of the diseases which can cause jaundice. It happens when a mother's blood type is O, and her baby's blood type is A or B. The mother's immune system may react and make antibodies against her baby's red blood cells. The consequences and treatment are similar to Rhesus disease.

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.

The Rh Factor: How It Can Affect Your Pregnancy

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. By now a considerable number of instances of the disease attributed to maternal anti-A or anti-B antibodies has been recorded all over the world.

Management of Pregnancy with ABO Incompatibility

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.

ABO Incompatibility

Rh blood group system

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 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.

Начиная с этого момента его связь с Халохотом стала не только мгновенной, но и абсолютно неотслеживаемой. Первое послание, которое он отправил Халохоту, не оставляло места сомнениям, тем более что они это уже обсуждали: убить Энсея Танкадо и захватить пароль. Стратмор никогда не спрашивал у Халохота, как тот творил свои чудеса: тот просто каким-то образом повторял их снова и. Энсей Танкадо мертв, власти убеждены, что это сердечный приступ, прямо как в учебнике, кроме одного обстоятельства. Халохот ошибся с местом действия. Быть может, смерть Танкадо в публичном месте была необходимостью, однако публика возникла чересчур. Халохот был вынужден скрыться, не успев обыскать убитого, найти ключ.
