Purpose: to assess the frequency of ABO and Rh blood groups among Saudi and non-Saudi healthy blood donors and to compare between them. Methods: A retrospective study was conducted; in Makkah City, Saudi Arabia. It included 15,365 participants of 44 nationalities who have attended the blood bank of King Abdul Aziz Hospital. The collected data were age, sex, nationality, ABO, and Rhesus blood groups.  Results: 46.8 % of the participants were O, 28.8 % A, 19.5 % B, and 4.9% AB. The nationalities with a higher frequency of blood group O were Saudi, Mauritanian, Yemeni, Thai, Malian, Sudanese, Jordanian, Indian, Moroccan, Somali, Malaysian, Indonesian, Myanmar, Nigerian, Pakistani, Bangladeshi, Algerian, Djibouti, Burkinabe, Eritrean, Ghanaian, Bahraini, Bosnian, Canadian, Gambian, Iraqi, and Sri Lankan. Those with a higher frequency of blood group A were Turkish, Palestinian, Syrian, Lebanese, Egyptian, Afghan, Chadian, French, Tunisian, Cameroonian, Ethiopian, and British.  Those with a higher frequency of B were Nigerien, American, Nepalese, and two nationalities with higher AB frequency Filipino and Chinese. 91.6 % of all populations were Rh-positive, and 8.4% were Rh-negative. The Saudi participants were like some nationalities and differed from others. Conclusion:  In Makkah city, the higher frequency of ABO blood group in Saudi and non -Saudi people is O followed by A, then B, and AB.  The Rh-positive is predominant, and 8.4% of the participants are negative. The ABO and Rh blood groups' identifications are essential for providing suitable blood storage for individuals in need.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are counted as a public health issue worldwide. The virus is transmitted to infect others through blood and blood products. Appointed blood groups and Rh-positive are more prone to the transmission of the infection by blood transfusion. The aim of this study is to find out the frequency of hepatitis B and C in apparently healthy blood donors and whether there is an association between ABO and Rh blood groups. ABO blood groups and their relationship with HBV and HCV infections were studied in 87,124 blood donors of both genders. Out of these donors, 353 individuals were found to be infected with HBV and HCV with a ratio of 1:250. The study was conducted between January to June 2018, which was presented to the Central Blood Bank in Baghdad and Al-Razi Medical Centre. It found that most hepatitis B and C blood donors were blood group O with a prevalence of 33.7 and 45.5%, respectively, while the results for those with blood group A showed 28.5 and 22.7% HBV and HCV infections, respectively. On the other hand, the incidence of HBV in individuals with blood group B was 29.8%, and HCV was 23.8%. AB blood group donors demonstrated the least incidence at 7.9% for both HBV and HCV. In conclusion, it has been found that there is a significant association between blood groups and Rh factor with hepatitis B and C infections.

ABO, Rhesus D and subgroups of ABO are highly immunogenic and are the common cause of antibody production in mismatched blood transfusions, haemolytic transfusion reaction and maternal alloimmunization. The aim of this study was to determine the occurrence of ABO, Rh D and subgroups of ABO among blood donors attending Specialist Hospital Sokoto, Nigeria. ABO, Rhesus D and subgroups of ABO antigen status of 176 blood donors with mean age of 30.44 ± 8.210 years attending Specialist Hospital Sokoto were determined using tile method for ABO and Rh D and conventional tube method for anti- A1, anti- H reagents for ABO subgroups respectively. Among the 176 subjects tested, blood group O+ was the most frequent group with 93 (52.8%), 39 (22.2%) were blood group B+, 37(21.0%) were blood group A+, 5 (2.8%) were blood group AB+, 2 (1.1%) were blood group O-. No data was obtained for A-, B- and AB- blood groups.  Out of 37 A blood groups obtained, 31 (83.8%) had A1 antigens and 6 (16.2%) had A2 antigens. Out of the 5 AB blood groups, all had A1B antigens. The study also shows that there was statistically significant difference between blood group A and ethnic groups (Hausa, Fulani and Yoruba) (p<0.05). Blood group O was found to be the most frequent followed by B, A and AB except among Hausa which revealed a pattern of O> A> B> AB. ABO, subgroups shows majority had A1 followed by A2 and A1B respectively.

To evaluate the relationship between ABO blood group and thrombosis, we studied 127 patients tak ing oral anti-vitamin K drugs for thromboembolism pro phylaxis and compared them with 700 voluntary blood donors. There were 68 patients with venous thrombosis (VT)—68 with deep vein thrombosis and 8 with pulmo nary embolism—and 51 patients with arterial embolism (AE). There were 61 men and 66 women. Mean age at diagnosis was lower for all women, regardless of if they had VT or AE (43 years) than for men (55 years; Kruskal- Wallis test, p < 0.01). There was an imbalance between blood group A and O frequencies in patients with VT versus blood donors, with a higher frequency of blood group A or a lower frequency of blood group O, repre sented by a high A/O ratio. A/O ratio for blood donors was 0.63; it was 1.50 for men (Fisher test, p = 0.028) and 1.44 for women (Fisher test, p = 0.010). Patients with AE showed the same discrepancy, but it was significant for women (A/O = 2.25; Fisher test, p = 0.026) and not for men (A/O = 0.86; Fisher test, p = 0.836), suggesting that men with AE might have other risk factors for thrombo sis. These data are not conclusive about the causes of the association between ABO blood groups and thrombosis, and prospective studies are needed to verify whether blood typing could have a predictive value for prophylatic measures in clinical and surgical patients.

Certain Rh positive blood groups showed a link between the ABO blood grouping and susceptibility to some infectious ailments. Study was carried out to find the association of ABO Blood Group System / Rh type with different viral infection. A retrospective observational study was carried in 7631 blood donors to find the association of ABO Blood Group System / Rh type with viral infection due to hepatitis B virus, hepatitis C virus, human immunodeficiency virus and Syphilis. Data of the study indicateF that the highest incidence of blood group in blood donor was B followed by O, A and AB. The incidence of HBsAg +ve, HCV Ab +ve and infection of Syphilis was also highest in donor with blood group B followed by O, A and AB. Blood group A were more susceptible to HIV Ab +ve followed by blood group B, O and AB. The group B donors had the greatest risk of viral infection with HBV, HCV, HIV, and Syphilis; followed by the groups O, A, and AB. Donors in group AB had the lowest incidence rate of all viral infection. The study revealed that blood group B is most prevalent among donors, followed by blood groups O, A, and AB. On the other side, the rate of HBV, HCV, HIV, and Syphilis infection was greatest among group B donors, followed by group O, group A, and group AB. Copyright(c) The Authors

Introduction: Conflicting evidences exist that ABO blood groups correlate with the susceptibility to COVID-19 and its clinical outcomes. This study aimed to pool available articles that assessed a possible relationship between COVID-19 and ABO blood groups. Materials and methods: A search was conducted in four databases comprising Pubmed/Medline, Google scholar, Journal storage (JSTOR) and African Journals Online (AJOL) for relevant studies available before 25th August 2020 and contained extractable data on ABO blood type distribution and COVID-19 disease. Search terms included a combination of “ABO blood group, and COVID-19, coronavirus, and SARS-COV-2”. Results: Fourteen articles that met study inclusion criteria were selected from a total of five hundred and eighty-five articles identified through database search. The fourteen articles reviewed comprised of a total of 73934 subjects (13189 SARS-COV-2 positive cases and 60745 controls). Overall, the risk of SARS-COV-2 infection was found to be significantly increased in patients with blood group A with ORs: 1.24 (95%Cl: 1.09-1.41, P = 0.001). Additionally, blood group O subjects were seen to have decreased odds of contracting COVID-19 infection (OR: 0.78, 95%Cl: 0.68 – 0.89, P=0.0003). No significant association was found between ABO blood groups and COVID -19 severity and mortality. Conclusions: Blood group A was associated with a higher risk of SARS-COV-2 infection whereas risk of infection was lower in blood group O subjects. No statistical significant association was found between ABO blood groups and COVID-19 severity and mortality. The precise role of ABO blood group in COVID-19 susceptibility, severity and mortality requires further research for clarification.

AbstractBackground and objectiveThe ABO blood group system has been associated with infectious and noninfectious disease, including dengue, hepatitis B virus (HBV), and severe respiratory syndrome coronavirus (SARS), etc. Coronavirus disease 2019 (COVID-19) is the ongoing pandemic with multitude of manifestations and association of ABO blood group in South-East Asian population needs to be explored.MethodsIt was a retrospective study of patients with real time polymerase chain reaction (RT-PCR) diagnosis of COVID-19 at Advanced Diagnostics and Liver Center between April 2020 to January 2021. Blood group A, B, O, and AB were identified in every participant, irrespective of their RH type and allotted groups 1, 2,3, and 4, respectively. Cox regression and logistic regression were used for inferential statistics.ResultsThe cohort included 1067 patients: 521 (48.8%) of blood group O, 295 (27.6%) of blood group B, 202 (18.9%) of blood group A, and 49 (4.5%) of blood group AB. The majority of the patients were males 712 (66.7%) with an average body mass index (BMI) of 27.45 ± 3.53. Patients with AB blood group stayed a median (IQR) of 14 (5, 27) days while A blood group cohort stayed 13 (6,27) days and overall 10.6% COVID-19-related mortality was observed at our center, with 13.9% in blood group A as the majority of COVID-19 deaths. Regarding severity of COVID-19 disease, there was a trend towards critical disease in blood group A and O (n=83, 41.1%; n=183, 35.1%; OR, 11.34 (95% CI, 46.79-53.22); p<0.001). Logistic regression demonstrates blood group O and AB as predictors for severe COVID-19 disease (O: OR: 0.438 (95% CI: 0.168-1.139) p=0.090; AB: OR: 0.415 (95% CI: 0.165-1.046) p=0.062) and cause-specific hazards ratio (HR) for survival function was 3.206 (p=0.361) among all blood groups.ConclusionAlthough the prevalence of blood group O was higher in this cohort, hospital stay, severity of disease, and mortality were associated with blood group A. Further studies are needed for understanding the underlying mechanism behind the association of blood groups with COVID-19.

Background and objectives: ABO blood group distribution defers with racial and geographic variations. They are related with diseases like cardiovascular diseases, cerebral thromboembolism. Prothrombin time may varies among ABO blood group system which may increase the future risk of thrombosis. The present study is to assess prothrombin time among ABO blood groups in healthy adults. Materials and methods: A prospective type of analytical cross-sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka from July 2019 to June 2020. After obtaining ethical clearance, a total 190 healthy adults were selected from different areas of Dhaka city based on inclusion and exclusion criteria, with age ranging from 18-45 years. The subjects were interviewed and detailed history regarding personal, family, medical and drug were taken. Prior to sample collection, informed written consent was taken from the participants. Individuals of blood group A was selected as group A, blood group B as group B, blood group AB as group AB and blood group O as group O. Prothrombin time was measured in the Department of Hematology and BMT Unit, Dhaka Medical College Hospital, Dhaka. Blood grouping was done in the Department of Physiology, Dhaka Medical College, Dhaka.For statistical analysis, One way ANOVA followed by Bonferroni test were considered using SPSS 25.0 version. Results: In this study, blood group B was most common (33.2%). Prothrombin time was lower in blood group A (12.93±0.30 sec), B (12.92±0.61 sec), AB (12.98±0.54 sec) than blood group O (13.08±0.39 sec) which was not statistically significant. Conclusion: It can be concluded that blood group A, B, AB individuals may have more chance of thrombosis due to lower prothrombin time than blood group O individuals.

AbstractIntroductionThe relationship between ABO blood group and the incidence of COVID-19 infection and death has been investigated in several studies. The reported results were controversial, so the objective of the present study is to assess the relationship between different blood groups and the onset and mortality of COVID-19 infection using meta-analysis method.MethodsWe searched the databases using appropriate MeSH terms. We screened articles on the basis of titles, abstracts, and full texts and the articles that met the inclusion criteria were selected. Quality assessment was done with the Newcastle-Ottawa Scale checklist. The estimated frequency of COVID-19 infection and death in terms of ABO blood group and the overall estimate of the odd ratio between blood group with COVID-19 infection and death was done with 95% confidence interval.ResultsThe pooled frequency of blood groups A, B, O, and AB among COVID-19 infected individuals was estimated as 36.22%, 24.99%, 29.67%, and 9.29% respectively. The frequency of blood groups A, B, O, and AB among the dead cases due to COVID-19 infection was estimated as 40%, 23%, 29%, and 8% respectively. The odd ratio of COVID-19 infection for blood group A versus the other blood groups was estimated 1.16 (CI 95%: 1.02-1.33). The corresponding figures for blood groups O and AB versus other blood groups were estimated as 0.73 (CI 95%: 0.60-0.88) and 1.25(CI 95%: 0.84-1.86) respectively.ConclusionThis meta-analysis showed that individuals with blood group A are at higher risk for COVID-19 infection while those with blood group O are at lower risk. Although the odds ratio of death for AB blood group was non-significant, it was considerable.

The clinical outcome of falciparum malaria in endemic areas is influenced by erythrocyte polymorphisms including the ABO blood groups. Studies have reported association of ABO blood group to resistance, susceptibility, and severity ofP. falciparummalaria infection. Individuals with blood group “A” have been found to be highly susceptible to falciparum malaria whereas blood group “O” is said to confer protection against complicated cases. We analyzed samples from 293 young children less than six years old with malaria in the Korle-Bu Teaching Hospital in Accra, Ghana. It was observed that group O was present in about 16.1% of complicated cases weighed against 40.9% of uncomplicated controls. Individuals with complicated malaria were about twice likely to be of blood groups A and B compared to group O (A versus O, OR = 1.90, 95% CI = 1.59–2.26,P<0.0001; B versus O, OR = 1.82. 95% CI = 1.57–2.23,P<0.0001). Blood group O participants with complicated diseases had low parasitaemia compared to the other blood groups (P<0.0001). This may give blood group O individuals a survival advantage over the other groups in complicated malaria as suggested. Participants with complicated falciparum malaria were generally anaemic and younger than those with uncomplicated disease.

BACKGROUND The association between antigens A and B and cardiovascular disease is still unclear. Several reports have suggested an important involvement of the ABO blood group system in the susceptibility to thrombosis. Assessing that non-O blood groups in particular A blood group confer a higher risk of venous and arterial thrombosis than group O. Epidemiologic data are typically not available for all racial and ethnics groups. The purpose of this observational study was to identify a probable link between ABO blood group and ischemic and non-ischemic disease in subjects from the province of Casablanca, Morocco and to analyze whether A blood group individuals were at higher risk of ischemic disease or not. METHOD An observational study had been conducted from the beginning of 2017 until the end of 2019 in the Department of Cardiology, University Hospital Centre, Ibn Rochd, Casablanca, Morocco. We recruited consecutive subjects (549 men and 544 woman) at our center between 2017 and 2019. We studied data on age, gender, past history of hypertension, diabetes, smoking, sedentarism, obesity, hyperlipidemia, use of estrogen-progestin contraceptives and blood group distribution. Their ABO blood groups were determined using standard agglutination techniques. In each blood group type, we evaluated the prevalence of ischemic and non-ischemic cardiovascular disease. RESULT Of the 1093 patients whose medical records were reviewed, 482 (44.1%) were carrying blood group A. Of the remaining 611 patients, 353 (32.3%) had blood group O, 212 (19.4%) blood group B, and 46 (4.3%) blood group AB. The diagnosis of ischemic disease (ID) was higher in patients with blood group O (63.3%) than in other blood groups, and the diagnosis of valvular disease was higher in patients with blood group A (48.7%) compared to other groups. In patients with blood group B or AB compared to non-B or non-AB, respectively there was no statistically significant difference in ID incidence. The incidence of ID in men was significantly higher in blood group O (63.2%, p = 0.015) compared with women, while there valvular disease was a statistically higher in women (54.5%, p = 0.035). This difference remains statistically significant after adjustment for common cardiovascular risk factors. CONCLUSION Our study suggests an association between ABO blood group and Ischemic disease and non-ischemic disease in Moroccan population. In African countries, where most of health facilities are understaffed, more rigorous studies with a larger population are needed to give high level of evidence to confirm this association in order to establish the need to be more aggressive in risk factor control in these individuals.
