Abstract Background A few people infected by the coronavirus become seriously ill, while others show little to no signs of the symptoms, or are asymptomatic. Recent researches are pointing to the fact that the ABO blood group might play an important role in a person’s susceptibility and severity of COVID-19 infection. Aim of the study: try to understand the relationship between ABO groups and COVID-19 (susceptibility and severity). Results A total of (507) patients were included in this study. The study population was divided based on the ABO blood group into types A+, A−, B+, AB, O+, and O−. Blood group A was associated with high susceptibility of infection: group A, 381 (75.1%); and less common in group O, 97 (19.2%), group B, 18 (3.5%), and group AB, 11 (2.2%). The severity of COVID-19 infection was common in non-blood group O where (20 (7.1%), 4 (26.7%), 2 (11%), and 1 (9%) in type A+, A−, B+, and AB, respectively), while in type O 3.1%. And mechanically ventilated patients were 22 (5.9%), 2 (13.4%), 2 (11.1%), and 1 (1%). Mortality was high in blood groups A and B, 16 (4.37%) and 1 (5.5%), respectively, while in blood group O, it was 1%. Conclusion The incidence, severity, and mortality of COVID-19 were common in non-blood group O. While blood group O was protected against COVID-19.

<p class="abstract"><strong>Background:</strong> Atrophic rhinitis is very common in India. All etiological factors are yet unknown.  Many studies have been conducted to find the relationship between ABO blood group and various systemic diseases but limited number of studies has been conducted to determine the association of ABO blood group with atrophic rhinitis. The present study therefore was performed to see the association between atrophic rhinitis and ABO blood group.</p><p class="abstract"><strong>Methods:</strong> 100 patients of both genders clinically diagnosed with atrophic rhinitis were included in this study. Patients with nasal obstruction, nasal discharge and foul smelling from causes other than the atrophic rhinitis were excluded from the study.  </p><p class="abstract"><strong>Results:</strong> Maximum number of cases 27 (27%) were between 21-30 years of age. The most common presenting symptom in our study was foul smell from nose in 100 cases (100%). Foetors, crusts and roomy nasal cavity were seen in majority of cases. Commonest organism identified in this study was <em>Pseudomonas aeruginosa</em> 37% followed by <em>Klebsiella</em> (31%). Out of 100 patients, 42 patients belonged to group O, 40 patients belonged to group B, 14 patients belonged to group A and only 4 patients belonged to group AB. Control population with blood group B comprises the maximum number of cases followed by blood group O. Percentage of patients with blood group O is higher in atrophic rhinitis as compared with control and the percentage of patients with blood group B is slightly higher in atrophic rhinitis as compared with control.</p><p class="abstract"><strong>Conclusions:</strong> Our study concluded that no correlation exists between the ABO blood group and atrophic rhinitis.</p>

Objective: This study aimed to examine the pathological changes in gastric mucosa of Helicobacter pylori-infected peptic ulcer patients carrying different ABO phenotypes and to study the response to the 14 days’ standard triple therapy and 10 days’ quadruple therapy in peptic ulcer patients according to their ABO phenotypes.Methods: Interventional prospective randomized-controlled open-label study was performed on newly diagnosed patients with PUD. The H. pylori-positive patients were allocated into two major study groups in which they are subdivided according to ABO blood group phenotypes: Group 1 received standard H. pylori eradication triple therapy and Group 2 received standard H. pylori eradication quadruple regimen. Patients were monitored after 2 months for successful H. pylori eradication.Results: Chronic active gastritis was significantly high in patients carrying blood Group O phenotype (81.25%), while the atrophic gastritis and intestinal metaplasia were significantly high in patients carrying blood Group A phenotype (25.00% and 16.67%), respectively. 14 days’ triple therapy showed significantly lower eradication rate in H. pylori-infected peptic ulcer patients carrying blood Group O phenotype (p<0.01), meanwhile higher response was found among patients with blood Group B. 10 days’ quadruple therapy produced a significant high eradication rate in H. pylori-infected patients carrying blood Group O than those with blood Group A (p<0.01), but still both showed lower response compared to that in patients carrying blood Group B and AB phenotypes. Elderly patients showed significantly less healing efficacy than younger patients (p<0.01), and the least healing rate was noticed in female patients after both regimens.Conclusion: Lower eradication rate in H. pylori-infected was noticed in peptic ulcer patients carrying blood Group O mainly than those with other blood groups and particularly those with duodenal Ulceri. 10 days’ quadruple therapy showed significant higher eradication rate in H. pylori infection and a better ulcer healing efficacy.

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.

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.

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.
