Kong Y, Xiao J, Tian L, Xu Y. The influence of HLA allele and haplotype on RhE alloimmunization among pregnant females in the Chinese Han population. Vox Sang 2024. [PMID: 38637118 DOI: 10.1111/vox.13641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 03/26/2024] [Accepted: 04/05/2024] [Indexed: 04/20/2024]
Abstract
BACKGROUND AND OBJECTIVES Anti-E alloantibody is the most common and important red blood cell (RBC) alloantibody during pregnancy. The study aimed to determine the correlation between RhE alloimmunization and human leukocyte antigen (HLA) allele polymorphism, as well as haplotype diversity, among pregnant individuals in the Chinese Han population. STUDY DESIGN AND METHODS All individuals included in our study were RhE-negative pregnant women of Chinese Han ethnicity, confirmed through serological testing. Pregnancy could be the only potential stimulating factor in RBC alloimmunization. Given the serological testing, the participants were divided into anti-E (responders) and non-anti-E-producing group (non-responders). The class I and II classical HLA genotyping were determined using next-generation sequencing, and the HLA genotype and haplotype frequencies were compared between the responders and non-responders. RESULTS In total, 76 responders and 94 non-responders were enrolled in this study. Comparison results showed that all HLA class I alleles had no difference between the two groups. For HLA class II phenotypes, responders had higher frequencies of HLA-DRB1*09:01, HLA-DQA1*03:02 and HLA-DQB1*03:03 phenotypes than non-responders, and the differences were statistically significant (pc < 0.05). In addition, the haplotype frequency of HLA-DRB1*09:01-DQA1*03:02-DQB1*03:03 in the RhE responders was significantly higher than in the non-responders (31.58% vs. 12.77%; odds ratio, 3.154; 95% confidence interval, 1.823-5.456; pc value, 1.25 × 10-3). CONCLUSION Our findings indicated that HLA-DRB1*09:01, HLA-DQA1*03:02 and HLA-DQB1*03:03 might be susceptible alleles for RhE alloimmunization among Chinese Han pregnant females. These three susceptible alleles constituted the unique three-locus haplotype in the RhE responders and collaborated to RhE alloimmunization.

Abstract
RhD alloimmunization in pregnancy is still the main cause of hemolytic disease of the fetus and neonate (HDFN). Nevertheless, there are other antigens that may be associated with the occurrence of this phenomenon and that have been growing in proportion, given that current prevention strategies focus only on anti-RhD antibodies. Although not widespread, the screening and diagnostic management of the disease caused by these antibodies has recommendations in the literature. For this reason, the following review was carried out with the objective of listing the main red blood cell antigen groups described - such as Rh, ABO, Kell, MNS, Duffy, Kidd, among others - addressing the clinical importance of each one, prevalence in different countries, and recommended management when detecting such antibodies during pregnancy.

Abstract
BACKGROUND Anti-M antibodies are relatively common and naturally occurring. When anti-M antibodies cross the placenta, they may cause hemolytic disease of the fetus and newborn (HDFN). Anti-M antibodies account for less than 15 cases of HDFN reported in the published English literature. HDFN can lead to foetal anaemia, hydrops fetalis, hypoxia, heart failure, and even death. OBJECTIVE To review the general guidelines and propose a less intensive management approach of anti-M antibody during pregnancy through the context of a case report. METHODS We report a 25-year-old healthy pregnant G3P1011 woman presenting for antepartum care. At the time of delivery for the patient's second pregnancy, she was found to have a positive anti-M blood screen, though she birthed a healthy-term infant. For her current pregnancy, the initial and repeat testings for anti-M were positive. RESULTS Since multiple samples from this patient were of low levels extensive maternal and foetal monitoring were deemed unnecessary in reflection of further reading and research. The patient had a spontaneous vaginal delivery of her third pregnancy at 38 weeks without complications. CONCLUSION Anti-RBC antibodies, including anti-M, are frequently identified in blood type and screening for pregnant patients. Guidelines call for intensive surveillance during pregnancy; however, knowledge of the specific antibody can help to provide more nuanced and less intensive care. As primary care physicians, being familiar with the guideline and the ability to counsel patients on anticipated care during pregnancy can help with family planning, compliance with testing, and patient anxiety and decrease intensive use of services that may not affect outcomes.

Abstract
Background/Aim. Pregnancy-induced red blood cell (RBC) alloimmunization is important not only because of the possible negative effects on subsequent pregnancy outcomes in case the fetus carries the antigen but also because of the optimal trans-fusion management in cases of obstetric hemorrhage. Timely detection of RBC antibodies is part of testing, prevention, and treatment strategy, aimed at achieving better outcomes for alloimmunized mothers with an affected fetus. The aim of the study was to determine the frequency and specificity of alloantibodies among pregnant women from the South Backa District, Serbia, with special attention to the incidence of anti-D alloantibodies. Methods. A retrospective study was conducted in the Blood Transfusion Institute of Vojvodina and covered the period from January 1, 2010, to December 31, 2019. Screening and antibody identification were performed by an indirect antiglobulin test in gel-microcards (ID-Card Liss/Coombs) with two test RBC (ID-DiaCell I-II screening cells, Bio-Rad, Cressier, Switzerland) on an automated system (IH-500, Bio-Rad). Results. Among 25,694 tested pregnant women, 1.38% were actively immunized, while 1.12% of women acquired antibodies in the current pregnancy. Among 3,622 (14.09%) RhD-negative women, 1.77% produced anti-D antibodies during the ongoing pregnancy. Distribution of anti-body specificity was: anti-D 23.34%, anti-M 11.85%, anti-E 9.41%, anti-K 9.41%, anti-C 5.92%, anti-Fyb 5.92%, anti-c 3.13%, anti-S 3.13%, anti-Lea 3.13%, anti-Leb 3.13%, anti-Cw 1.75%, anti-Jka 1.40%, anti-P 1.05%, anti-Lub 0.70%, anti-Fya 0.35%, autoantibody of undetermined specificity 0.70%, and irregular antibodies of undetermined specificity 15.68%. Conclusion. Immunoglobulin prophylaxis has led to a significant reduction in the frequency of D-alloimmunization among pregnant women in the South Backa District over the last ten years. However, the incidence of anti-D antibodies is still significantly higher than in published data for developed countries. We also identified the other, less commonly present, clinically significant antibodies. There is a need to introduce uniform recommendations for immunohematological testing in pregnancy on the territory of the Republic of Serbia in accordance with modern requirements.

Abstract
BACKGROUND Red blood cell alloimmunisation during the pregnancy is a significant cause for neonatal mortality and morbidity. This study was planned to determine the prevalence and specificity of irregular erythrocyte antibodies in antenatal mothers and their neonatal outcome. METHODS In this observational study, blood grouping and red cell antibody screening of mothers were performed at first visit and after 28 weeks of gestation and positive cases were identified and followed up monthly till delivery by repeating antibody titre and middle cerebral artery-peak systolic velocity. After delivery of alloimmunised mothers, cord blood haemoglobin, bilirubin and direct antiglobulin tests (DAT) were analysed and further outcome of neonate was recorded. RESULTS Among 652 registered antenatal cases, 18 multigravida women were found to be alloimmunised, accounting to prevalence of 2.8%. Most common alloantibody identified was anti D (>70%) followed by anti-Lea, anti-C, anti-Leb, anti-E and anti-Jka. Only 47.7% Rh D negative women received anti-D prophylaxis during previous pregnancies or whenever indicated. DAT was positive in 56.2% of neonates. Among nine DAT positive neonates, two early neonatal deaths due to severe anaemia were observed following birth resuscitation. Four antenatal mothers required intrauterine transfusion in view of fetal anaemia while three neonates received double volume exchange transfusion and top up transfusions after birth. CONCLUSIONS This study emphasises importance of red cell antibody screening for all multigravida antenatal women at registration of pregnancy and additionally at 28 weeks or later in high-risk cases irrespective of RhD status.

Abstract
Hemolytic disease of fetus and newborn (HDFN) imposes great healthcare burden being associated with maternal alloimmunization against parental-inherited fetal red blood cell antigens causing fetal anemia or death. Noninvasive prenatal analysis (NIPT) provides safe fetal RHD genotyping for early identification of risk pregnancies and proper management guidance. We aimed to conduct systematic review and meta-analysis on NIPT's beneficial application, in conjunction with quantitative maternal alloantibody analysis, for early diagnosis of pregnancies at risk. Search for relevant articles was done in; PubMed/Medline, Scopus, and Ovid (January 2006April 2020), including only English-written articles reporting reference tests and accuracy data. Nineteen eligible studies were critically appraised. NIPT was estimated highly sensitive/specific for fetal RHD genotyping beyond 11-week gestation. Amplifications from ≥2 exons are optimum to increase accuracy. NIPT permits cost-effectiveness, precious resources sparing, and low emotional stress. Knowledge of parental ethnicity is important for correct NIPT result interpretations and quantitative screening. Cut-off titer ≥8-up-to-32 is relevant for anti-D alloantibodies, while, lower titer is for anti-K. Alloimmunization is influenced by maternal RHD status, gravida status, and history of adverse obstetrics. In conclusion, NIPT allows evidence-based provision of routine anti-D immunoprophylaxis and estimates potential fetal risks for guiding further interventions. Future large-scale studies investigating NIPT's non-RHD genotyping within different ethnic groups and in presence of clinically significant alloantibodies are needed.

Abstract
Unexpected anti-red blood cell (RBC) alloantibodies are routinely investigated in immunohematology and blood banking since their existence in pregnant women may induce haemolytic disease of the foetus and newborn, and their presence in donors may induce haemolytic transfusion reactions or hyperacute rejection in solid organ transplantation. Unexpected anti-RBC alloantibodies may target antigens of the most blood types excluding the expected antibodies targeting the ABO antigens. Their incidence in humans was originally linked to alloimmunization events such as blood transfusions, transplants, or pregnancies. But later, many findings revealed their existence in pathogenic processes such as malignancies, infections, and autoimmune diseases; and usually (but not always) associated to autoimmune haemolytic anaemia (AIHA). Nevertheless, unexpected anti-RBC autoantibodies are also occasionally found in healthy individuals in the absence of AIHA and with no history of alloimmunization or the associated pathologic processes. Hence, they are generally known as non-clinically significant, are excluded for typification and called "silent red blood cell autoantibodies (SRBCAA)". This review highlights evidence related to genetic predisposition, molecular mimicry, immune dysregulation, and immune tolerance loss surrounding the existence of anti-RBC antibodies, describing the presence of SRBCAA as possible early witnesses of the development of autoimmune diseases.

Abstract
Background Rhesus D (RhD) antigen alloimmunization has been a focus of concern for hematologists and obstetricians. It contributes to perinatal morbidity and mortality. The objectives of this study were to assess the awareness of pregnant women toward the clinical importance of blood group Rh(D)-negativity and anti-D immunoglobulin and to determine the prevalence of blood group Rh(D)-negativity among them. Methods and materials This cross-sectional study was conducted in a routine antenatal care clinic of King Abdullah Hospital in Bisha, Saudi Arabia from September 2018 to January 2019. The awareness of pregnant women toward the clinical importance of blood group Rh(D)-negativity and prophylaxis with anti-D immunoglobulin was assessed through a self-administered questionnaire. Samples were analyzed for ABO and Rh (D) blood groups using the microplate grouping method. The presence of anti-D alloantibodies was detected by the indirect antiglobulin test. Data were analyzed by IBM SPSS Statistics for Windows, Version 25.0 (Armonk, NY: IBM Corp.). A p-value ≤0.05 was considered statistically significant. Results A total of 108 respondents fulfilled the inclusion criteria and completed the survey. Forty-five pregnant women (41.7%) were observed to be aware of the blood group Rh(D)-negativity and anti-D immunoglobulin issue. The prevalence of the negative blood group was 11.1% (12/108). Awareness was found to be significantly associated with age, education, vaginal bleeding, blood groups, and previous administration of anti-D immunoglobulin (p-value ≤0.05). Conclusion The prevalence of blood group Rh(D)-negativity among respondents was found to be comparative with other populations, although the overall awareness was found to be suboptimal (41.7%). Structured health education programs by hematologists and obstetricians are needed to increase awareness and to address women at reproductive age.

Abstract
INTRODUCTION The objective of the analysis was to examine the epidemiological aspects of maternal alloimmunization and to determine the most common antibody specificities resulting in hemolytic disease of the newborn (HDN). MATERIALS AND METHODS The retrospective epidemiological study encompasses all pregnant women who underwent immunohematological screening and the newborn treated for HDN in the period from 2000 to 2013 in the Herzegovina region. RESULTS The indirect Coombs test (ICT) detected antibodies against antigens in 384 (2.4%) pregnant women of the 18 800 who were tested at the Department of Transfusion Medicine. The direct Coombs test (DCT) detected antibodies against antigens in 160 (0.8%) newborn treated for HDN. The results of our 13-year study, in which 60% of the pregnant women had non-RhD antibodies, confirms this finding. CONCLUSION However, we have reached the 21st century and the burden of alloimmunisation in pregnancy is still on our backs. The problem of immunization and HDN is still present in our region, which is a neonatal and public health problem.

Abstract
Background Alloimmunisation due to irregular erythrocyte antibodies is a recognised cause of hemolytic disease of the fetus and newborn (HDFN). Prior knowledge of red cell alloimmunisation in pregnant females guides the obstetrician to monitor the foetus for HDFN and if required for appropriated intervention. As limited data are available on prevalence of red cell alloimmunisation in pregnant females in India, the current study was carried out to know the prevalence of red cell alloimmunisation in pregnant females coming at our laboratory. Methods Screening for irregular erythrocyte antibodies was performed in 1960 pregnant females after obtaining informed consent between June 2015 and June 2016. MatrixTM screening and identification reagent red cells from Tulip Diagnostics (P) Ltd were used, and column agglutination technique was employed as a method for the test. Results Twenty antibodies (all of single specificity) were detected in 1960 samples giving a prevalence rate of alloimmunisation of 1.02%. Out of the 20 antibodies, 18 were identified to be anti-D, 1 was anti-c and 1 antibody was anti-H. The results obtained were then compared with those reported in the literature. Conclusion Red cell alloimmunisation is not uncommonly observed in pregnant females; the information gained can help the obstetrician to identify high-risk cases to timely start antenatal and post-natal treatment. Obstetricians should request screening for irregular red cell antibody desirably in all pregnant females; however, if limiting factors are there, it should be done at least in select group of pregnant females having bad obstetric history.
