Article Abstract
Background: Blood group irregular antibody is a major factor that may cause adverse pregnancy outcomes. We aimed to emphasize the importance of prenatal blood antibody screening and popularize antenatal care knowledge by sharing a case of hydrops fetalis caused by anti-E and anti-c alloimmunization antibodies.
Methods: We retrospectively analyzed the clinical and laboratory data of a pregnant woman with repeated fetal edema caused by anti-E and anti-c irregular antibodies. Irregular antibody screening, antibody identification, and antibody titer detection were performed.
Results: A pregnant woman aged 30 years old, in whom hydrops fetalis was found by color Doppler ultrasound at 32 + 5 gestation weeks. Irregular antibody screening was positive and anti-E and anti-c were detected in plasma. The results were negative by saline method. Antibody titers of anti-E and anti-c were 1,024 and 128, respectively, and Rh blood group was CCDee (R1R1). Eventually, a fatal termination had to be chosen for serious hydrops fetalis.
Conclusions: Hydrops fetalis, stillborn fetus, and kernicterus are the severest outcomes of hemolytic disease of the fetus and newborn (HDFN). Anti-E and anti-c are common alloantibodies that lead to adverse fetal outcomes. Such adverse pregnancy outcomes can be minimized by improving pregnant women's awareness of HDFN and reinforcing the management of irregular blood group antibodies during pregnancy.

Background: Pregnancy causes immunisation when the fetal red cells, possessing a paternal antigen foreign to the mother, enter the maternal circulation, resulting in the production of alloantibodies. Maternal allo-immunisation, also known as iso-immunization, occurs when a woman's immune system is sensitised to foreign erythrocyte surface antigens, stimulating the production of immunoglobulin G (IgG) antibodies. This study was carried out to determine the frequency of maternal Red blood cell alloantibodies in Gwarimpa General Hospital, FCT, Abuja, and to evaluate the clinical utility of antibody screening.

Fetal hydrops can stem from immune or nonimmune causes. Immune causes often involve red cell alloimmunization, whereas nonimmune causes encompass structural malformations, aneuploidy, infections, lymphatic system disorders, genetic syndromes, and more. In a rare and complex case, we encountered a fetal hydrops presentation characterized by blended phenotypes, indicating both a genetic and an underlying immune etiology.

Introduction: Hemolytic disease of the fetus and newborn (HDFN) is a serious complication in pregnancy and still remains a cause of perinatal mortality, in developing countries. Antibodies to other red blood cell antigens, leading to hemolysis, are being recognized. The aim of the study is to report the outcomes in women undergoing intrauterine transfusions (IUT) for fetal anemia due to rhesus alloimmunization over the last two decades, over 3 time periods from 2002 to 2021 and to report the prevalence of minor antibodies at our center and their effect on perinatal and neonatal outcomes.

Background: Red cell antibodies of a certain specificity are produced following the immunization of a corresponding antigen-negative individual through pregnancy or transfusion, such as RhCcEe allogeneic infusion. The transfusion incompatibility of RhC/c and RhE/e can be estimated based on the proportion of the RhCcEe phenotype. DEL has been positively correlated with RhC and RhE phenotypes.
