“…Moreover, D– blood groups are uncommon among the Omani population. We report an ABO distribution in transfusion‐dependent β‐thalassemia patients that is consistent with other reports among Omani subjects . The prevalence of partial D genotypes in Omani and in the other populations in the Arabian Peninsula is unknown and worth further study.…”

“…Unlike published data of Egyptian, Iranian, and Indian populations, we report a very low rate of anti‐D alloimmunization in our patients. This is probably explainable by the existing transfusion policy of provision of D– blood to D– patients, the existing protocols in preventing D alloimmunization in Oman, and the fact that pregnant thalassemia patients were managed and continued to receive their transfusion support in our center. Moreover, D– blood groups are uncommon among the Omani population.…”

“…The prevalence of Rh(D)-negative blood groups varies in ethnic populations, with approximately 15.8% of Caucasians, 8% of Blacks, and 1% of Asians [6]. The prevalence of negative blood group revealed by this study is more than that reported by the Netherlands (8.9%), a previous Saudi study (7.5%), Nigeria (4.5%), and Oman (7.3%), and it is less than that reported by Pakistan (13.6%) [6][7][8][9][10]. This finding appears to be comparable with other ethnic groups.…”

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).

“…In Oman, the distribution of the blood groups and Rh-D factor among pregnant women at Sultan Qaboos University Hospital (2011 -2013) showed that blood group O represented 52.2%, followed by A (26.5%), B (16.3%) and AB (5.1%). The Rh positive was 92.8% while the Rh negative was 7.2% [21].…”

Blood groups are specific to individuals and are important laboratory investigations in transfusion medicine, tissue transplants and genetic disputes. They exhibit similar serological and physiological characteristics and are inherited according to specific pattern. Thus it was chosen to assess the blood group's awareness among the Omani people during the period of 2012-2016.The required information was collected from designed questionnaires that include several variables and based on similar previously conducted studies in different parts of the world. All the participants appeared to be healthy and educated. A total of 1800 questionnaires have been distributed in six different regions (willayates) in Oman. Nearly equal number of males and females were participated in the study.The results show that blood group O+ is the dominant blood group (49.1%), followed by A+ (19.7%), B+ (17.5) and AB+ (4.7%). In addition, ABO negative groups were only reported in one region and represented a total of 0.7%, although the blood group of 8.3% of the participant was not determined.In the present investigation, the majority of the participants seem to be familiar with the blood and its constituents and all of them were found aware of the blood donation, possible diseases transmitted by blood transfusion and the use of the donated blood. In addition, the majority (72%) were seemed familiar with the hereditary blood disorders. However, the association of the ABO blood groups with serious diseases reported in various studies was difficult to be assessed. All the findings are illustrated in a table and histograms using Microsoft Excel programs and the important, relevant, issues are discussed.

Red Cell Alloimmunization to Rhesus Antigen Among Pregnant Women Attending a Tertiary Care Hospital in Oman

Abstract: The prevalence of RhD negativity was comparable to other Asian countries. Previous RhD alloimmunization and history of miscarriages were the most common maternal medical history.
