Background. Determination of the various ABO/Rh blood group distributions and their association with malaria infection has paramount importance in the context of transfusion medicine and malaria control. Methods. Facility based cross-sectional study was conducted from February to June, 2015, to assess ABO/Rh blood groups distribution and their association with asymptomatic malaria. A structured questionnaire was used to collect data. Blood grouping was done using monoclonal antibodies. Thin and thick blood films were examined for Plasmodium parasites. Data were analyzed using SPSS version 20.0. Results. A total of 416 blood donors participated with median age of 22±0.29 (median ± standard error of the mean). Distribution of ABO phenotypes, in decreasing order, was O (175, 42.1%), A (136, 32.7%), B (87, 20.9%), and AB (18, 4.3%). Most of them were Rh+ (386, 92.8%). The overall malaria prevalence was 4.1% (17/416). ABO blood group is significantly associated with malaria infection (P=0.022). High rate of parasitemia was seen in blood group O donors (6.899, P=0.003) compared to those with other ABO blood groups. Conclusion. Blood groups O and AB phenotypes are the most and the least ABO blood groups, respectively. There is significant association between ABO blood group and asymptomatic malaria parasitemia.

Objective: The present study investigates the seroconversion time course of the IgG antibody against SARS-CoV-2 and ascertains whether its levels change according to the patient’s ABO blood group. Method: A total of 36,003-convalescent plasma (CP) donations of 12,315 Turkish Red Crescent CP donors were analyzed. The ABO blood group of the CP donors was determined by Gel Centrifugation; and IgG was measured using the Euroimmun anti-SARS-CoV-2 ELISA. The differences in the distributions of mean IgG ratios among the different ABO blood groups were analyzed with One-Way ANOVA and Independent Samples T-test. Results: Among the CP donors, 98.4% were male. An antibody response to SARS-CoV-2 was noted-although in a few CP donors- on the 244th day, and a significant association between the ABO blood groups and the mean IgG ratios was noted (p: 0.001). The highest (mean±SD) antibody level was observed in the AB blood group (39.5±15.7), followed by the B (37.9±11.5) and the A blood groups (36.6±10.7), while the lowest value was recorded in the O blood group (34.4±11.5). Significant differences between all paired groups were noted in pairwise comparisons. The Rh (-) blood group (37.4±13.6) had a significantly higher antibody level than the Rh (+) blood group (36.3±11.2) (p: 0.005). Conclusion: An antibody response to SARS-CoV-2 was noted in a CP donor on the 244th day. The average IgG ratios were higher in the CP donors with the AB blood group, but lower in the O blood group. These results may be considered a valuable indication of the effectiveness of CP therapy used for the treatment of COVID-19 patients with clinically relevant blood types.

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: Few studies focused on the study of blood groups in Gabon. This study aimed to determine the phenotypic frequency of ABO and Rhesus antigens in blood donors of Libreville and to assess the association between ABO blood groups and transfusion-transmitted infections.Materials and Methods: The study of ABO and Rhesus blood groups concerned 4,744 blood donors. ABO and Rhesus phenotyping were obtained using monoclonal monospecific antisera: anti-A, anti-B, anti-AB, anti-D, anti-E, anti-C, anti-c, and anti-e with an automate (QWALYS® 3, DIAGAST, France) or a card gel (ID Card, BIO-RAD) according to manufacturer’s instructions.Results: The phenotypic frequency of blood group antigens A, B, AB and O were respectively 21.0%; 17.6%; 2.6% and 58.9%. Those of rhesus antigens D, d, C, c, E and e were 97.7%; 2.3%; 15.9%; 99.9%; 17.6%; 99.3%, respectively. The prevalence of ABO and Rh antigens in Gabonese donors reported here are significantly different from those of neighboring countries. No association was found between the prevalence of HIV, HCV and syphilis and ABO blood groups. Instead, HBV seroprevalence was twice as high among non-O blood groups donors compared with blood group O donors [OR = 2 (CI 1.26 to 3.2), p = 0.003].Conclusions: This study provides new data on phenotypic frequency of ABO and Rh blood groups in a representative sample of the Gabonese blood donor population. It suggests a significant association between ABO blood group and HBV infection.

Introduction: Coronavirus disease 2019 (COVID-19) disease severity differs widely due to numerous factors including ABO gene-derived susceptibility or resistance. The objective of this study was to investigate the association of the ABO blood group and genetic variations of the ABO gene with COVID-19 severity in a heterogeneous hospital population sample from the United Arab Emirates, with the use of an epidemiological and candidate gene approach from a genome-wide association study (GWAS).Methods: In this cross-sectional study, a total of 646 participants who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were recruited from multiple hospitals and population-based (quarantine camps) recruitment sites from March 2020 to February 2021. The participants were divided into two groups based on the severity of COVID-19: noncritical (n = 453) and critical [intensive care unit (ICU) patients] (n = 193), as per the COVID-19 Reporting and Data System (CO-RADS) classification. The multivariate logistic regression analysis demonstrated the association of ABO blood type as well as circulating anti-A antibodies and anti-B antibodies as well as A and B antigens, in association with critical COVID-19 hospital presentation. A candidate gene analysis approach was conducted from a GWAS where we examined 240 single nucleotide polymorphisms (SNPs) (position in chr9: 136125788-136150617) in the ABO gene, in association with critical COVID-19 hospital presentation.Results: Patients with blood group O [odds ratio (OR): 0.51 (0.33, 0.79); p = 0.003] were less likely to develop critical COVID-19 symptoms. Eight alleles have been identified to be associated with a protective effect of blood group O in ABO 3'untranslated region (UTR): rs199969472 (p = 0.0052), rs34266669 (p = 0.0052), rs76700116 (p = 0.0052), rs7849280 (p = 0.0052), rs34039247 (p = 0.0104), rs10901251 (p = 0.0165), rs9411475 (p = 0.0377), and rs13291798 (p = 0.0377).Conclusion: Our findings suggest that there are novel allelic variants that link genetic variants of the ABO gene and ABO blood groups contributing to the reduced risk of critical COVID-19 disease. This study is the first study to combine genetic and serological evidence of the involvement of the ABO blood groups and the ABO gene allelic associations with COVID-19 severity within the Middle Eastern population.

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.

OBJECTIVE: To determine the frequency of ABO blood groups among patients with acute myocardial infarction in the Pakistani population STUDY DESIGN: Cross-sectional study PLACE AND DURATION OF STUDY : Department of Interventional Cardiology, Rawalpindi Institute of Cardiology, Rawalpindi, from May 2015 to November 2015. METHODOLOGY: A total of 250 subjects with acute myocardial infarction were included in the study. The study was explained to the patients and informed consent taken. All patients underwent 12 lead electrocardiography using Mortara instrument ELI 250 and were analyzed by a single trained reader unaware of the patients’ blood group. Cardiac troponin levels were assessed at least three hours after the onset of symptoms. The ABO blood group was assessed by using the standard slide agglutination method in the hospital pathology laboratory and verified by the principal investigator. The data was collected on a pre-tested questionnaire by the investigator after taking informed consent from the patient. RESULTS: In our study, the mean age of patients was 57.3 years. 36.4% were between 18-50 years of age while 63.6%were between 51-80 years of age. 79.2% were male and 20.8% were females. Frequency of ABO blood groups among patients with acute myocardial infarction in our study population was recorded as 28.8% with O +ve , 26% with B+ve, 18.4% with A+ve, 13.2% with AB +ve, 5.6% with A-ve, 4.4% with B-ve, 3.2% with O-ve and 0.4% with AB -ve CONCLUSION: We concluded that the frequency of acute myocardial infarction in our population is higher among patients having blood group O+ve followed by B+ve blood group.

1572 Background: The role of genetic factors in the development of cancer is widely accepted. ABO blood type is an inherited characteristic and previous studies have observed an association between ABO blood group and risk of certain malignancies, including pancreatic and gastric cancer. The data on the role of ABO blood group and Rh factor in breast cancer is inconclusive. Methods: All patients who had breast cancer (BC) and treated between 2000-2010 at the Departments of Medical Oncology of both Ankara and Hacettepe Universities (Ankara, Turkey) with defined ABO blood type and Rh factor were included in our retrospective reviews of tumor registry records. A group of volunteer healthy women donors of Turkish Red Crescent between 2004-2011 were identified as a control group, without any matching factors. The relationship of ABO blood types and Rh factor with various prognostic factors such as age at diagnosis, menopausal status, family history of breast cancer, and ER/PR/HER2 status were evaluated from 1740 BC patients. We compared the distributions of ABO blood types, Rh factors among 1740 patients and 204,553 healthy controls. Among BC patients, differences between each of aforementioned ABO blood groups and Rh factors with respect to various prognostic factors were explored, respectively. Results: Overall distributions of ABO blood groups as well as Rh factor were comparable between patients (44% A, 8% AB, 16% B, 32% O, 88% Rh+) and controls (41% A, 8% AB, 16% B, 35% O, 87% Rh+). However, there were statistically significant differences between patients and controls with respect to A vs. nonA (p=0.019) and marginal significance (p=0.051) for O vs. nonO. Among patients, there were statistically significant differences between A and nonA with respect to HER2 (p=0.0421), M stage (p=0.0447), T stage (p=0.0020). Only T stage (p=0.0337) were significantly different between O vs nonO. Grade (p=0.0227) and M stage (p=0.0107) were significantly different between Rh factors. Conclusions: In our study sample, ABO blood type was statistically significantly associated with breast cancer. Additional studies are necessary to determine the mechanisms by which ABO blood type may influence the risk of breast cancer.

Background and objectives: Blood screening is considered a compulsory procedure in health care services to reduce the occurrence of transfusion transmitted infections (TTIs). This study estimated the distribution rates of ABO and Rh blood group systems, prevalence rates of TTIs among blood donors and their association with the ABO blood group and Rh system. Materials and Methods: A retrospective study was conducted at the national blood bank, Amman, Jordan for a period of 6 years (from January 2013 to December 2018). For TTIs analysis, about 5 mL blood sample was collected from each volunteer. A total of 365,029 persons (346,048 (94.8%) males and 18,981 (5.2%) females) donated their blood at the national blood bank, Amman, Jordan from January 2013 to December 2018. Results: The results revealed that O and A were the most prevalent blood groups (37.44% and 36.82%, respectively), followed by B (18.62%) and AB (7.12%). The distribution of Rh + ve and Rh − ve among blood donors showed that Rh + ve donors were more prevalent (88.73%) compared with Rh − ve (11.27%). HBsAg was the most prevalent viral infection (0.38%) followed by HCV (0.13%), syphilis (0.02%), HIV (0.006%) and the male donors were highly infected when compared with female donors. The association between ABO/Rh blood groups and TTIs infections was nonsignificant. Conclusions: In conclusion, low frequency rates of TTIs among blood donors were detected in the current study, but improvements are still continuously required. Low percentages of female donors need to be managed via conducting health cultural education programs.
