Molecular analysis of patients with weak D and serologic analysis of those with anti-D (excluding type 1 and type 2)

Whether or not patients whose red blood cells (RBCs) carry certain weak D types  produce anti-D, and if they do whether it is  allo- or autoanti-D, remains controversial. The aim of this study was to determine the serologic features of anti-D in individuals expressing a weak D other than type 1 or type 2 and to assess whether the anti-D was an allo- or autoantibody. Serologic D typing and molecular analyses were performed on 748 individuals. Serologic characterization of anti-D

Use of LOR-15C9 monoclonal anti-D to differentiate erythrocytes with the partial DVI antigen from those with other partial D antigens or weak D antigens

Historically, red blood cells (RBCs) with partial D antigens have been defined serologically by their pattern of reactivity with polyclonal and monoclonal anti-D. Although numerous variants have been described in tests with well-characterized monoclonal anti-D, definition remains difficult to ascertain serologically. RBCs of known partial D type were tested with LOR-15C9 (a monoclonal anti-D) and commercial anti-D by the tube indirect antiglobulin test (IAT), by micro typing system IgG gel

Alloimmunization to the D antigen by a patient with weak D type 21

Antibodies of apparent D specificity may be found in D+ patients. We report a D+, multi-transfused Caucasian woman with myelodysplasia who exhibited several alloantibodies. One antibody was a moderately strong (2+) anti-D that persisted for 9 months, until the woman died. Molecular analysis of the patient’s RHD gene identified the rare weak D type 21 (938C>T) allele. D alloantibodies do not occur in patients with most weak D types, but some patients with a weak D phenotype, including

Incidence of weak D in blood donors typed as D positive by the Olympus PK 7200

The incidence of weak D has been reported to be between 0.23 and 0.5 percent in Europe and 3.0 percent in the United States. All studies were performed before the introduction of monoclonal anti-D reagents. Using current commercial reagents, this study evaluated D+ samples for the presence of weak D. D+ donors, typed by the Olympus PK 7200, using diluted monoclonal blend anti-D and diluted polyclonal anti-D, were selected by sampling batches of 100 to 200 samples from the previous day’s

Reactivity of FDA-approved anti-D reagents with partial D red blood cells

Individuals whose RBCs are characterized as having a partial D phenotype may make anti-D if exposed to normal D+ RBCs;thus it is desirable that they be typed as D– should they require blood transfusion or Rh immune globulin (RhIG) prophylaxis. Further, use of different anti-D reagents by blood centers and transfusion services can account for FDA-reportable errors. For this study,antiD reagents for use in tube tests were obtained from three U.S. manufacturers. They included three examples

Serologic and molecular characterization of D variants in Brazilians: impact for typing and transfusion strategy

Rh discrepancies are a problem during routine testing because of partial D or weak D phenotypes. Panels of monoclonal antibodies (MoAb) are being developed to identify D variants such as partial D and weak D when there are anomalous D typing results; however, molecular characterization offers a more specific classification of weak and partial D. The weak D and partial D phenotypes are caused by many different RHD alleles encoding aberrant D proteins, resulting in distinct serologic phenotypes

Weak D type 42 cases found in individuals of European descent

Patient samples were referred to our immunohematology reference laboratory to investigate the presence of a weak D antigen. In the last 3 years, 26 samples were received. Serology and molecular analyses were performed to identify the weak D variant. RHD mRNA from all patients was reverse transcribed, and cDNA was sequenced. The results were compared with a normal RHD sequence to identify the polymorphisms causing the weak D phenotype. Five different already known RHD variants were observed

Discrepancies in Rh(D) typing of sensitized red blood cells using monoclonal/polyclonal anti-D reagents: case report and review

Instructions included with monoclonal Rh(D) typing reagents do not require routine use of an Rh control as immunoglobulin-coated red blood cells (RBCs) rarely yield falsely positive results with low protein reagents. However, the American Association of Blood Banks (AABB) Technical Manual recommends a concurrent control be performed on patients’ RBCs that type as group AB, D+.

Prevalence of DEL phenotype in D– blood donors in India

Since the identification of the Rh factor more than seven decades ago, individuals are categorized as either D+ or D– depending on the presence or absence of D. D, in the Rh blood group system, is the most immunogenic of all blood group antigens. As little as 0.1–1 mL of D+ red blood cells (RBCs) can induce anti-D formation in D– recipients, which is responsible for severe transfusion reactions and hemolytic disease of the fetus and newborn.1 Antigen expression in the Rh system is influenced by

Rh is a complex blood group system with diverse genotypes that may encode weak and partial D variants. Standard serologic analysis may identify clinically significant D variants as D+; nevertheless, individuals with these D variants should be managed as D– patients to prevent antibody formation to absent D epitopes.

Comparative testing for weak expression of D antigen: manual tube testing vs. a semiautomated IgG gel system

Donor RBCs nonreactive in initial tests for D must be tested further for evidence of weak expression of D antigen. Performing this test in test tubes is labor intensive and prone to inconsistencies in readings (relative strength of agglutination) and interpretation (positive versus negative). These inconsistencies can lead to repeat testing, additional documentation, and delay in releasing units. We evaluated use of the Tecan MEGAFlex-ID™ pipettor to perform this test in anti-IgG gel

Identifying obstetrics patients in whom RHD genotyping can be used to assess risk of D alloimmunization

The D antigen is different from many other blood group antigens in that the antigen is not derived from one or a few amino acids, but rather from the presence of the entire protein; thus it contains many epitopes. Genetic variation within the RHD gene can alter expression of the antigen both qualitatively and quantitatively. A D protein that lacks one or more of the epitopes is referred to as a partial D antigen, and loss of epitopes is associated with risk of alloimmunization from exposure to

The anti-D titer increased with a pattern that suggested it was stimulated by the 8-week pregnancy. Six years before this admission, the patient’s blood type changed from group O, D+ to group O, D– after a bone marrow transplant for aplastic anemia. Three years after transplant

Comparison of estimation of volume of fetomaternal hemorrhage using KleihauerBetke test and microcolumn gel method in D-negative nonisoimmunized mothers

In this study we assessed the efficacy of the microcolumn gel method in the detection and quantification of the volume of fetomaternal hemorrhage (FMH) in comparison with the Kleihauer-Betke test (KB) in nonisoimmunized D– mothers. We collected blood samples from 80 D– indirect antiglobulin test–negative mothers over a span of more than 1 year. FMH was determined by KB and microcolumn gel method, and the results were compared. FMH was recorded as less than 4 mL by KB if no

Quantitating fetomaternal hemorrhages of D+ red cells using an FITC-conjugated IgG monoclonal anti-D by flow cytometry: a case report

Several methods for quantitating fetomaternal hemorrhages (FMHs) have been described; these include the Kleihauer-Betke and red cell rosetting tests, and flow cytometry that uses an indirect antiglobulin technique, employing either FITC-conjugated IgG/unlabeled anti-D or streptavidin conjugates with biotinylated anti-D to enumerate D+ red cells in maternal blood.

Development of a flow cytometric test for the detection of D-positive fetal cells after fetomaternal hemorrhage and a survey of the prevalence in D-negative women

A sensitive test for the presence of D-positive fetal red blood cells (RBCs) in the maternal circulation of D-negative women has been developed. It was used to investigate the possibility that the occasional failure in preventing alloimmunization might be due to the administration of inadequate amounts of prophylactic anti-D Rh immune globulin. The standard dose in Australia contains 125µg of antibody, and can suppress immunization by an estimated 6 mL of packed D-positive RBCs. A

Four months after a D– male was transfused with four units of D– red blood cells (RBCs), the results of a standard pretransfusion antibody screen and alloantibody identification panel detected anti-C+D in his serum. This report was interpreted by his physician to be evidence of alloimmunization to the D antigen, which triggered concern that the patient had been transfused previously with D+ RBCs as the result of an error in blood typing or personal identification.

Description of Deladenus brevis n. sp. (Sphaerularioidea: Neotylenchidae) from Iran: a morphological and molecular phylogenetic study

The genus Deladenus was erected by Thorne (1941) with D. durus (Cobb, 1922) Thorne (1941) as its type species. Compared to other genera in the family Neotylenchidae (Thorne, 1941), the genus is characterized by its low cephalic region, small stylet, pharyngo-intestinal junction anterior to nerve ring, excretory pore at the level with, or immediately behind the nerve ring, pharynx lacking a median bulb, long overlap of the glands, no post-vulval uterine sac (PUS), and males with bursa. The genus

registration cancellations or production interruption. Oxamyl and aldicarb have been important products for control of stubby-root nematodes and CRS as they have provided good control of these pathogens; often better control than fumigants (Weingartner and Shumaker, 1990a, 1990b; Weingartner et al., 1993). This has left growers reliant on a limited number of nematicides, particularly the fumigant 1,3-dichloropropene (1,3-D), or a combination of 1,3-D and ethoprop when CRS is present. Therefore, it is

Blood group genotyping in a multitrauma patient: a case report

Currently DNA-based analysis of blood groups is mainly used to improve transfusion safety by reducing alloantibody formation in multiply transfused patients and by monitoring pregnancies at risk for hemolytic disease of the fetus and newborn. We present a case in which genotyping was performed after massive transfusion with unmatched group O, D– blood in a trauma setting. Our patient was genotyped as O1A1 and predicted to be D–, and we therefore transfused group A, D– red

An example of anti-LWa in a 10-month-old infant

Blood samples from a 10-month-old male infant requiring transfusion were found to contain an allomtibody reacting at 37°C in saline, by indirect antiglobulin test (IAT), and with a manual polybrene technique. Preliminary results suggested anti-D and another weaker reacting antibody, but the patient had been previously transfused with only D- blood. His serum reacted more weakly by IAT against red cells treated with 0.2M dithiothreitol (DTT), and one D+, LW(a-) sample was nonreactive. The

Update on HDFN: new information on long-standing controversies

from anti-D was a significant cause of perinatal mortality or long-term disability. Routine administration of RhIG to D– women during pregnancy and shortly after the birth of D+ infants effectively reduced the incidence of HDFN caused by anti-D. Maternal alloimmunization to other RBC antigens in the Rh, Kell, and other blood group systems can not be routinely prevented and these antibodies can also cause HDFN. Advances in prenatal care, noninvasive monitoring, and intrauterine transfusion

Case report: IgG1 Rh antibodies causing moderate hemolytic disease of the newborn

A gravida 3, para 1, 32-year-old black female presented at 27 weeks gestation for routine prenatal serologic tests. She typed as group A, D positive, category DIII mosaic. IgG1 anti-D, -hrB, and -E were identified in her serum. Ultrasound revealed an apparently normal fetus with no evidence of hydrops or ascites. Amniocentesis, performed at 30, 33, and 35 weeks, showed some evidence of hemolysis that did not increase over time. At 36 weeks of gestation, she delivered a full-term infant who

Effects of HCN channel blockade on the intensity-response function of electroretinographic ON and OFF responses in dark adapted frogs

is by recording electroretinogram (ERG). The most prominent ERG components in response to long-lasting stimuli are the b-wave (ON response) and the d-wave (OFF response). In the ERGs obtained with brief (flash) stimuli, the OFF response is small and merges with the preceding ON-response. The role of the HCN channels in generation of ERG responses to stepped light stimuli has been mainly assessed by studying the effects of pharmacological blockade or genetic ablation of HCN channels on the flash

Severe hemolytic disease of the fetus and newborn due to anti-C+G

Anti-G is commonly present with anti-D and/or anti-C and can confuse serological investigations. In general, anti-G is not considered a likely cause of severe hemolytic disease of the fetus and newborn (HDFN), but it is important to differentiate it from anti-D in women who should be administered anti-D immunoglobulin prophylaxis. We report one woman with three pregnancies severely affected by anti-C+G requiring intrauterine treatment and a review of the literature. In our case, the

Rh immune globulin: an interfering substance in compatibility testing

Introduction Rh immune globulin (RhIG) is administered routinely to Rh-negative,* pregnant women to prevent hemolytic disease of the fetus and newborn (HDFN), to Rh-negative patients who have received Rh-positive blood components, and to patients as a treatment for immune thrombocytopenic purpura (ITP). The result of RhIG administration may be the presence of anti-D in the plasma of antepartum and postpartum Rh-negative women, occasionally in their newborns, and in patients with ITP. The number
