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.

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.

Objective: The study investigated the possibility of using blood groups as predictive indices for diseases associated with lipid metabolism. Methods: Lipid profiles were examined in 100 apparently healthy male (40) and female (60) subjects of different ABO blood groups aged between 18-30 years from Imo State University.  Of these, 20 were blood group A, 30 were B blood type, 4 were  AB blood type, and 46 were blood group O. Lipid profile parameters were determined according to enzymatic assay using a commercial kit from Randox Laboratories, United Kingdom and calculation using Friedewald’s equation. Monoclonal ABO blood grouping reagent by CLAS Technology, United Kingdom was used to determine the blood group.  Results: Total Cholesterol (140.62 ± 21.66 mg/dl) and High-Density Lipoprotein (HDL)                      (96.20 ± 40.32 mg/dl) were highest in blood group B. Blood group A had the highest level of Triglyceride (80.84 ± 18.60 mg/dl) and Very Low-Density Lipoprotein (VLDL) (15.21 ± 6.24 mg/dl). Blood group O showed TC level of 130.60 ±34.76 mg/dl with the highest level of LDL (70.74 ± 20.15 mg/dl) and the lowest level of HDL (51.68 ± 20.50 mg/dl) compared to non- O blood types                    (P < 0.05).  Conclusion: The study revealed that blood group O might have a higher propensity for dyslipidemia, suggesting an increased risk for disease associated with lipid metabolism.

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.

Abstract Background There has been an interest in the relationship between ABO blood groups and infertility. Many studies have investigated the association of ABO blood groups with diminished ovarian reserve (DOR), ovarian hyperstimulation syndrome (OHSS), and outcomes of assisted reproductive technology (ART), with controversial results. Methods A systematic review and meta-analysis was conducted to evaluating the association of ABO blood groups with DOR, OHSS, and outcomes of ART. Results Thirteen studies performed between 2010 and 2018 were included in this meta-analysis. DOR, OHSS, live birth rate (LBR), clinical pregnancy rate (CPR), miscarriage rate (MR) were reported in 9, 2, 4, 3, 2 studies, respectively. The combined results showed similar risk of DOR among individuals with blood group A (RR, 0.98; 95% confidence interval [CI], 0.85, 1.13), B (RR, 0.96; 95% CI, 0.76, 1.20), AB (RR, 1.00; 95% CI, 0.76, 1.30), and non-O (RR, 0.94; 95% CI, 0.79, 1.11) as compared to those with blood group O. Meta-analysis showed that the incidences of OHSS were similar in women with blood group A (RR, 1.05; 95% CI, 0.66, 1.66), B (RR, 1.04; 95% CI, 0.46, 2.35), AB (RR, 0.51; 95% CI, 0.10, 2.56), non-O (RR, 1.02; 95% CI, 0.65, 1.57) with blood group O. As to the clinical outcomes, meta-analysis showed no difference in LBR among individuals with blood group A (RR, 1.27; 95% CI, 0.74, 2.17), B (RR, 1.47; 95% CI, 0.95, 2.29), AB (RR, 1.48; 95% CI, 0.76, 2.90), non-O (RR, 1.28; 95% CI, 0.83, 1.98) when compared to those with blood group O. Similarly, the results also found that there were no difference in CPR and MR between women with blood A (CPR: RR, 1.12), B (CPR: RR, 1.08), AB (CPR: RR, 1.05), non-O (CPR: RR, 1.05; MR: RR, 0.94) and blood group O. Conclusions ABO blood groups may not be associated with DOR, OHSS, LBR, CPR, and MR of ART. Infertility and ART outcomes are influenced by multiple factors. Blood groups should not be taken into account excessively during diagnosis and treatment of infertile women.

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.

Introduction 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. Methods It was a retrospective study of patients with COVID-19. 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. Correlation between blood group and lab parameters was presented as histogram distributed among the four groups. Multivariate regression and logistic regression were used for inferential statistics. Results The cohort included 1067 patients: 521 (48.8%) participants had blood group O as the prevalent blood type. Overall, 10.6% COVID-19-related mortality was observed at our center. Mortality was 13.9% in blood group A, 9.5% in group B, 10% in group C, and 10.2% in AB blood group (p = 0.412). IL-6 was elevated in blood group A (median [IQR]: 23.6 [17.5,43.8]), Procalcitonin in blood group B (median [IQR]: 0.54 [0.3,0.7]), D-dimers and CRP in group AB (median [IQR]: 21.5 [9,34]; 24 [9,49], respectively). Regarding severity of COVID-19 disease, no statistical difference was seen between the blood groups. Alteration of the acute phase reactants was not positively associated with any specific blood type. Conclusion In conclusion, this investigation did not show significant association of blood groups with severity and of COVID-19 disease and COVID-19-associated mortality.

ObjectiveNasopharyngeal carcinoma (NPC) is a common malignant tumour in Southeast Asia, especially in southern China. ABO blood groups have been proven to play an important role in many cancers. However, it is still controversial whether the ABO blood group has a definite relationship to susceptibility to NPC and the prognosis of NPC patients. This meta-analysis was performed to elucidate the correlation between ABO blood group and NPC to provide more data for clinical practice.MethodsA systematic search was performed of the Chinese National Knowledge Infrastructure (CNKI), Wanfang, Web of Science, EMBASE, and PubMed databases up to December 31, 2020. Stata 11.0 statistical software was used for this meta-analysis.ResultsAccording to the inclusion and exclusion criteria, a total of 6 studies including 6938 patients with NPC were selected. Blood group O was relevant to Chinese NPC patients, and patients with blood group O had a significantly lower incidence of NPC, while blood group A had no correlation with susceptibility to NPC. There was no difference in the 3-year overall survival (OS), locoregional relapse-free survival (LRRFS) or distant metastasis-free survival (DMFS) rates between patients with blood group O and those with non-O blood groups; worse 5-year OS, LRRFS and DMFS rates were found in patients with blood group O, whereas blood group A was not related to prognosis.ConclusionBlood group O in Chinese patients with NPC seems to be a protective factor for morbidity. However, once patients with blood group O are diagnosed with NPC, this blood group often indicates unfavourable OS, LRRFS and DMFS rates. It is recommended that more attention should be paid to the influence of blood group factor on patients in the treatment of NPC.

BACKGROUND: Inherited ABO blood group has been shown to play an important role in the pathogenesis of various gynecological cancers including endometrial carcinoma (EC). OBJECTIVE: Our study aimed to determine the prevalence of ABO blood groups in Iranian patients with EC and to investigate the relationship between the blood group and several clinicopathologic parameters in Imam Hossein Hospital. METHODS: One hundred and seventy-five EC patients were selected and analyzed for their clinicopathologic details including ABO blood group, age, menopausal status, body mass index (BMI), tumor grade, and stage of the International Federation of Obstetrics and Gynecology (FIGO). RESULTS: Endometrioid carcinoma was the most common histological type in this case study. Early stages (I and II) were present in 135 individuals (77.1%) and advanced stages (III and IV) appeared in 40 (22.9%) patients. Blood group A was prominent in patients with EC. There was a significant relationship between blood group A and cancer grade (P= 0.024). 23.1% of group A had grade III EC, while this grade appeared in 35.2% of the non-A blood group. There was no significant association between ABO blood groups and other EC clinic-pathological results (P> 0.05). CONCLUSION: Although there was no significant relationship between the ABO blood group and the patients’ clinicopathological characteristics, more studies could provide extensive information about any possible relation between the blood group, especially blood group A, EC, and the grade of the tumor.

Background Globally, studies have shown conflicting results regarding the association of blood groups with SARS CoV-2 infection. Objective To observe the association between ABO blood groups and the presentation and outcomes of confirmed COVID-19 cases. Design, setting, and participants This was a prospective cohort study of patients with mild-to-moderately severe COVID-19 infections who presented in the COVID-19 unit of Dhaka Medical College Hospital and were enrolled between 01 June and 25 August, 2020. Patients were followed up for at least 30 days after disease onset. We grouped participants with A-positive and A-negative blood groups into group I and participants with other blood groups into group II. Results The cohort included 438 patients; 52 patients were lost to follow-up, five died, and 381 completed the study. The prevalence of blood group A [144 (32.9%)] was significantly higher among COVID-19 patients than in the general population (p < 0.001). The presenting age [mean (SD)] of group I [42.1 (14.5)] was higher than that of group II [38.8 (12.4), p = 0.014]. Sex (p = 0.23) and co-morbidity (hypertension, p = 0.34; diabetes, p = 0.13) did not differ between the patients in groups I and II. No differences were observed regarding important presenting symptoms, including fever (p = 0.72), cough (p = 0.69), and respiratory distress (p = 0.09). There was no significant difference in the median duration of symptoms in the two group (12 days), and conversion to the next level of severity was observed in 26 (20.6%) and 36 patients (13.8%) in group I and II, respectively. However, persistent positivity of RT-PCR at 14 days of initial positivity was more frequent among the patients in group I [24 (19%)] than among those in group II [29 (11.1%)]. Conclusions The prevalence of blood group A was higher among COVID-19 patients. Although ABO blood groups were not associated with the presentation or recovery period of COVID-19, patients with blood group A had delayed seroconversion.
