BACKGROUND: Red blood cell (RBC) antigen matching policies to prevent alloimmunization in females of childbearing potential (FCP) vary between centers. To inform transfusion centers responsible for making decisions about matching policies for FCPs, the causal stimulus of the antibodies implicated in severe hemolytic disease of the fetus and newborn (HDFN) must be determined. STUDY DESIGN AND METHODS: We conducted a multinational retrospective study of women with offspring affected by severe HDFN requiring neonatal exchange transfusion and/or intrauterine transfusion...

BACKGROUND: Neonatal hyperbilirubinemia is influenced by a wide variety of factors, one of which is hemolysis. Serious hyperbilirubinemia may lead to a kernicterus with detrimental neurologic sequelae. Patients suffering from hemolytic disease have a higher risk of developing kernicterus. Carbon monoxide (CO), a byproduct of hemolysis or heme degradation, was described by Sjöstrand in the 1960s. It is transported as carboxyhemoglobin (COHb) and exhaled through the lungs. We were interested in a potential correlation between COHb and total serum bilirubin (TSB) and the time course of both parameters...

REVIEW
Shaun Lawicki, Randal B Covin, Amy A Powers
The Kidd blood group system was discovered in 1951 and is composed of 2 antithetical antigens, Jk(a) and Jk(b), along with a third high-incidence antigen, Jk3. The Jk3 antigen is expressed in all individuals except those with the rare Kidd-null phenotype. Four Kidd phenotypes are therefore possible: Jk(a+b-), Jk(a-b+), Jk(a+b+), and Jk(a-b-). The glycoprotein carrying the Kidd antigens is a 43-kDa, 389-amino acid protein with 10 membrane-spanning domains which functions as a urea transporter on endothelial cells of the renal vasa recta as well as erythrocytes...

BACKGROUND: To evaluate the incidence, the consequences, and the prevention strategy of anti-D alloimmunizations of D variant carriers in the obstetric population of Split-Dalmatia County, Croatia. METHODS: RhD immunization events were evaluated retrospectively for the period between 1993 and 2012. Women were tested for RhD antigen and irregular antibodies. Those with anti-D antibody who were not serologically D- were genotyped for RHD. They were evaluated for their obstetric and transfusion history and their titer of anti-D...

We report a case of dramatic outcome of severe hemolytic disease in a newborn due to RH1 incompatibility. A newborn with A RH1 blood group was admitted in the Mohammed V Military Teaching Hospital for the problem of hydrops fetalis associated with RH1 incompatibility. The blood group of his mother, aged 31, was AB RH1-negative and that of his 37 year old father was A RH1. The mother had a history of 4 term deliveries, 3 abortions, and 1 living child. There was no prevention by anti-D immunoglobulin postpartum...

BACKGROUND: The rare M(k) M(k) phenotype is the result of a deletion of the coding regions of both GYPA and GYPB. Red blood cells (RBCs) of individuals homozygous for the rare M(k) gene lack all MNS blood group antigens and have no glycophorin A or glycophorin B. This phenotype is extremely rare and only four families have been reported. CASE REPORT: A 28-year-old woman was referred for assessment of recurrent early neonatal deaths. She was found to be apparently homozygous for M(k) ...

Fiber enhanced resonance Raman spectroscopy (FERS) is introduced for chemically selective and ultrasensitive analysis of the biomolecules hematin, hemoglobin, biliverdin, and bilirubin. The abilities for analyzing whole intact, oxygenated erythrocytes are proven, demonstrating the potential for the diagnosis of red blood cell related diseases, such as different types of anemia and hemolytic disorders. The optical fiber enables an efficient light-guiding within a miniaturized sample volume of only a few micro-liters and provides a tremendously improved analytical sensitivity (LODs of 0...

BACKGROUND: Minor red blood cell antibodies are becoming a more common cause of hemolytic disease of the newborn. Anti-U are a rare alloantibody found almost exclusively in people of black descent. There is limited experience to guide the management of pregnancies complicated by anti-U. Furthermore, there is often no suitable cross-matched blood available for transfusion of a patient with anti-U. CASE REPORT: A 21-year-old P0G1 presented at 25 weeks' gestation with D- disease in pregnancy...

Fetal anemia and hydrops may be caused by parvovirus B19 infection and maternal alloimmunization to RhD with subsequent hemolytic disease of the fetus and newborn. The use of intrauterine transfusion over the last few decades has dramatically improved outcomes. Prior literature has extensively documented placental changes associated with untreated parvovirus infection and RhD HDFN in intrauterine fetal demises (IUFD) and pre-term births; however, histopathologic changes in term placentas from term infants treated with IUT have not been reported...

BACKGROUND: RhIG prophylaxis for D- pregnant women prevents hemolytic disease of the newborn and typically depends on results of serologic D typing. Interpretation and follow-up of weak D serology is variable. Recent recommendations promote genotyping for RHD status determination in those with weak D serology. Canadian Blood Services performs comprehensive serologic prenatal testing in four provinces. Genotyping is used to determine D typing in patients with weak D. STUDY DESIGN AND METHODS: A serologic algorithm identified which patients require genotyping for RHD determination...

Anti-M antibody, which is not reactive at 37°C, is not clinically significant. Reports of clinically significant anti-M antibodies causing hemolytic disease of the fetus and the newborn (HDFN) and delayed hemolytic transfusion reaction (DHTR) are available. We report 13 cases of anti-M antibodies reactive at room temperature (RT) and at 37°C. These were found in patients of varied age groups (11 months to 85 years) with varied clinical diagnosis. All the female patients were multigravida. In all cases, antibody screening was positive at RT as well as at the indirect antiglobulin test (IAT) phase...

INTRODUCTION: Hemolytic disease of the fetus and newborn (HDFN) is caused by the destruction of fetal red blood cells due to red cell antibodies produced by the mother. HDFN can cause fetal hydrops during pregnancy or neonatal jaundice after birth. Direct Antiglobulin Test (DAT) detects antibodies bound to red cells and is a valuable test aiding in the diagnosis of HDFN. In Iceland DAT is routinely performed on cord blood or newborn blood samples if the mother is Rhesus D negative or has non-A/B red cell alloantibodies...

Most adverse blood transfusion (BT) events are immune-mediated and in the majority of severe reactions antibodies can be identified as causal factors. Alloimmunization not only causes symptomatic reactions, transfused cells can also be (silently) destroyed. Immunization by BT can contribute to hemolytic disease of the newborn as well as to allograft rejection after transplantation. Reversely, pregnancy and transplantation may evoke immunity hampering transfusion therapy. Besides causing mortality and morbidity, alloimmunization has a huge economic impact...
