The study was undertaken to assess the distribution of the ABO blood groups in Kaduna metropolis, Nigeria. Blood group types of forty-three thousand, nine hundred and nineteen (43,919) people were collected from eight different hospitals in Kaduna metropolis over a period of four years. These hospitals are easily accessible by all groups and classes of people because of their location. Phenotypic and allelic frequencies were determined to understand the distribution pattern of the ABO blood groups. A chi-square test was carried out to test whether the population was in Hardy-Weinberg equilibrium. The O blood group occurred with the highest frequency (44.13%), while the AB blood group had the lowest occurrence of 3.98%. Blood group A was more predominant (29.12%) than B blood group (22.77%). The O allele had the highest allelic frequency (0.67), while the A and B alleles were lower (0.19 and 0.14 respectively). The ABO blood group system was found to be in Hardy-Weinberg equilibrium.

Background: Transfusion transmitted infections (TTIs) involves several adverse consequences. Studies have shown that ABO blood groups have some association with various infectious and non-infectious diseases. Few blood groups even can act as a receptor and ligand for infectious agents. The objective of the study was to find out any significant association of TTIs with various ABO and Rh D blood group system.Methods: This retrospective study was conducted from July 2016 to October 2018. Blood donors’ blood was tested for ABO and Rh D grouping and five mandatory TTI markers as per Drugs and Cosmetics Act. Chi-square test was performed to look for any association of TTIs with ABO and Rh D blood group.Results: 10,510 healthy donors were screened for TTI and 199 (1.89%) were positive for various TTIs. Hepatitis B had maximum prevalence (102 cases, 0.97%) followed by Hepatitis C (44 cases, 0.41%) and HIV (37 cases, 0.35%). Maximum TTI seroreactive donors were found among ‘B’ blood group (2.21%, 77 cases) followed group ‘A’ donors (2.16%, 53 cases), ‘O’ donors (1.57%, 60 cases) and ‘AB’ donors (1.17%, 9 cases), respectively. However, the risk of association of TTI was not statistically significant with ABO and Rh D blood group.Conclusions: Although no significant association was observed between ABO and Rh D blood groups with TTIs, Hepatitis B was found to be most common infection in blood donors. This high prevalence points towards critical need of comprehensive public health approach to achieve elimination of TTI.

The present study is a retrospective analysis of allelic frequency of ABO and Rhesus (D) blood groups of donors attending the Deaprtment of Transfusion Medicine of Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM), Dhaka. BIRDEM IS a 625 bed hospital, where patients and blood donors come from all parts of Bangladesh. A total of 1, 28,506 blood donors of both genders were included in the study over fourteen years from June 1995 to June 2009 for analysis. Blood group was determined by performing the both tube and slide method blood grouping method. The distribution of blood groups in our population was B>O>A>AB in Rh positive groups donors and O>B>A>AB among Rh negative donors. Blood group B was more common among the males (37.42%) while O was predominant among female donors (33.83 %). On the other hand, blood group O negative was predominant in both genders (36.88%). In this study, Hardy- Weinberg equilibrium law was used to calculate the allelic frequency for ABO/ Rh system. Homozygous allelic frequency for Rh negative population was only 0.0007. Although phenotypically B group was dominant and AB was rare in our population, but according to Hardy- Weinberg equilibrium law the estimated allelic frequency of A (0.3694) and O (0.3040) showed higher frequency than B type (0.2300) in Bangladeshi population in both homozygous and heterozygous state. So, with increasing population of Bangladesh, this changing trend in estimated blood group in ABO system may play an important role in our genetic pattern.

The ABO blood group system was discovered by Karl Landsteiner in 1901. Since then, scientists have speculated on an association between different pathologies and the ABO blood group system. The aim of this pilot study was to determine the significance between different blood types of the ABO blood group system and certain pathologies. We included 237 patients with known diagnosis, blood group, sex, and age in the study. As a statistical method, the Chi-square test was chosen. In some cases, a significant association between the blood groups and defined diseases could be determined. Carriers of blood group O suffered from ulcus ventriculi and gastritis (X21 = 78.629, p <0.001), colitis ulcerosa and duodenitis (X21 = 5.846, p < 0.016), whereas male patients carrying blood group A tended to contract different types of tumours. In patients with intestinal tumours, females with blood group A were more likely to develop the pathology, whereas in males, the blood group O dominated. The development of cholelithiasis was found, above all, in patients with blood group O, which differed from other research where a correlation between this pathology and blood group A was found.

Background.Relationship between blood groups and dermatologic diseases remains controversial and was not yet fully elucidated nor explained clearly. The aim of this study was to examine if any relation exists between different types of pemphigoid diseases and ABO blood group.Methods.In this case-control study, 159 pemphigoid patients and 152 healthy matched-controls were evaluated. All blood group (including Rh status) data for the study was obtained from the hospital medical records. Statistical comparisons were completed with chi-square test and logistic regression.Results.Blood group “O” was found in 32.9% of patients and 38.2% of control group. Blood group “A” was found among 30.8% of patients and 34.2% of control group, while group “B” was reported in 27.4% of cases and 21.1% of controls and “AB” was identified among 8.9% of patients and 6.6% of control group. 84.9% of patients were Rh positive, while in the control group 86.2% of patients were Rh positive. No significant differences were found regarding ABO blood groups (P=0.46) or Rh (P=0.76) between pemphigoid patients and control group. Also, older females had the higher risk of developing bullous pemphigoid.Conclusion.We found no relationship between ABO blood groups and pemphigoid disease.

BackgroundABO and Rh blood group systems are associated with many diseases including cancerous, infectious, non-infectious, bacterial and viral diseases. Studies have shown association of blood groups A and O with higher and lower odds for coronavirus disease 2019 positivity, respectively.MethodsThis is a single-center, retrospective study conducted at Sir Ganga Ram Hospital, Delhi. We investigated the association of ABO and Rh blood groups with susceptibility to coronavirus disease 2019 infection, severity of disease, recovery period, and mortality of patients. Patients were enrolled from April 8, 2020 to October 4, 2020. A total of 2,586 real-time PCR (RT-PCR)-confirmed coronavirus disease 2019 (COVID-19) patients were recruited. Data was analyzed using chi-square test, odds ratio, and Mann–Whitney test to determine the association of blood groups.ResultsIn the 2,586 COVID-19-infected patients, the frequencies of A, B, O, and AB were 29.93%, 41.80%, 21.19%, and 7.98%, respectively. Of the patients, 98.07% were Rh positive. Blood group A (odds ratio, 1.53; CI, 1.40–1.66; p &lt; 0.001) and B (odds ratio, 1.15; CI, 1.06–1.24; p &lt; 0.001) is observed to be significantly associated with COVID-19 susceptibility, whereas blood group O (odds ratio, 0.65; CI, 0.59–0.71; p &lt; 0.001) and AB (odds ratio, 0.66; CI, 0.59–0.71; p &lt; 0.001) have low risk of COVID-19 infection.ConclusionA, B, and Rh+ are found to be more susceptible to COVID-19 infection, whereas blood groups O, AB, and Rh− are at a lower risk of COVID-19 infection. No association was found between blood groups and susceptibility to severity of disease and mortality.

Context: Distribution of blood groups varies among ethnic groups throughout the world. Blood groups of tribals should be determined as they are ethnically different from the main population of Bangladesh. Materials and Methods: To observe the distribution pattern of ABO and Rh blood groups and to compare the groups among Manipuris (1434) and Khasias (204), this descriptive crosssectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka, from July 2006 to June 2007. Manipuris were divided in Bishnupriya (658), Meitei (460) and Meitei-Pangan (316) according to their ethnic origin. Data were collected from Manipuri (12) and Khasia (2) localities selected by systematic random sampling. ABO and Rh blood groups of participants were determined by the antigen antibody agglutination test of slide method. Data from groups were compared by chi-square test with 95% confidence limit. Results: There are significant variations in the distribution of ABO (p<0.001) and Rh (p<0.001) blood groups among all study groups. Blood group A was more frequent among Meiteis (40%) and Meitei-Pangans (42.41%) whereas blood group O was more frequent in Bishnupriyas (47.72%) and Khasias (35.29%). In all tribal communities, AB blood group was least frequent. Rh positive participants (97.43%) were more than Rh negative (2.57%). In Khasias, no Rh negative group was found. Rh negativity was more in Bishnupriyas (4.9%) which was significantly higher than Meiteis (0.87%) and Meitei-Pangans. (1.94%) (X2=16.7; p<0.001). Conclusion: Distribution of ABO blood groups varies among the Manipuris and Khasias. Significant variation is also found in three groups of Manipuris and the distribution corresponds with the pattern of their ancestors.

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.

ABSTRACT Background: Blood group is a genetic characteristic which is associated with some diseases and deformities. Multifactorial characteristics of facial development make it difficult to predict a genetic pattern in a specific maxillofacial deformity, but epidemiological evaluations can reveal relationships between such deformities and some genetic characteristics or accompanied diseases, and this will help to recognise and treat them. The aim of this study is evaluation of the relationship between blood groups and maxillofacial deformities. Materials and Methods: In this study, blood groups of 190 patients with maxillofacial deformities who had had orthognathic surgery in Alzahra hospital, Isfahan, were compared with the general Iranian population. Results: Among 190 patients, 93 cases (49%) were men and 97 cases (51%) were women. Fifteen cases (8%) were < 20 years old, 130 cases (68%) were 20-30 years old, and the others (45 cases, 24%) were > 30 years old. The blood group distribution in our samples was as follows: blood group O = 76 cases (40%), blood group A = 58 cases (30%), blood group B = 41 cases (22%), and blood group AB = 15 cases (8%). Among these patients, 31 cases (16%) had maxillary deformities and 27 cases (14%) suffered from mandibular deformities while the other 132 cases (70%) had bimaxillary problems. The Chi-square test showed statistically significant differences between the blood group distribution of the patients of this study and the normal Iranian population ( P < 0.001). Conclusion: It was shown that among different blood groups; those with blood group B have a greater likelihood of association with maxillofacial deformities. On the other hand, the probability of the association of such deformities was the least with blood group A.

Abstract 1. A series of 1337 obstetric cases, of which 170 were instances of sensitized Rh negative women, were studied with regard to (a) the incidence of the ABO blood groups, and (b) the incidence of ABO compatibility between the mother and child. 2. The incidence of ABO compatibility between the mother and child was found to vary with the blood group of the mother. 3. ABO compatibility between the mother and child was found to be present in 80 per cent of an unselected obstetric population in contrast to 95 per cent in a group of sensitized Rh negative women who bore infants afflicted with hemolytic disease of the newborn. 4. ABO compatibility appears to be related to the occurrence of hemolytic disease of the newborn. 5. In 120 sensitized Rh negative women who bore afflicted infants, the incidence of group A mothers was greater than expected.
