Abstract The main purpose of this study was to find out a possible association between ABO blood groups or Rh and diabetes mellitus (DM) in the local population of eight (8) different towns of Karachi, Pakistan. For this purpose a survey was carried out in Karachi to have a practical observation of these towns during the period of 9 months from June 2019 to Feb. 2020. Out of eighteen (18) towns of Karachi, samples (N= 584) were collected from only eight (8) Towns of Karachi and gave a code-number to each town. Diabetic group sample was (n1=432) & pre-diabetes sample was (n2 =152). A standard Abbot Company Glucometer for Random Blood Sugar (RBS) and Fasting Blood Sugar (FBS) tests, standard blood anti sera were used for ABO/Rh blood type. Health assessment techniques were performed ethically by taking informed consent from all registered subjects. Finally data was analyzed by SPSS version 20.0. In our current study, the comparison of ABO blood groups frequencies between diabetic and pre-diabetic individuals were carried out. The percentage values of blood Group-B as given as: (32% in DM vs. 31% in pre-diabetics), followed by blood Group-O as: (18% in DM vs. 11% in pre-diabetics). Contrary to Group-“B” & “O”, blood Group-A and Group-AB were distribution percentage higher pre-diabetic as compared to DM patients, as given as: Group-A (32% in pre-diabetics vs. 26% in DM) & Group-AB (26% in pre-diabetics vs. 24% in diabetic’s patients). In addition, percentage distribution of Rh system was also calculated, in which Rh+ve Group was high and more common in DM patients as compared to pre-diabetics; numerically given as: Rh+ve Group (80% in DM vs. 72% in pre-diabetics). Different views and dimensions of the research topic were studied through literature support, some have found no any association and some established a positive association still some were not clear in making a solid conclusion. It is concluded that DM has a positive correlation with ABO blood groups, and people with Group-B have increased susceptibility to DM disease.

Background: This study was conducted to determine whether type 1 diabetes mellitus (T1DM) is associated with ABO & Rhesus (Rh) blood groups. Materials and Methods: This analytical cross sectional study was carried out on 77 patients suffering from T1DM and 96 healthy children less than 18 years old referring to Yazd Diabetes Research Center from April 2018 to May 2019. The ABO blood group and Rh factor in both groups were determined. Fasting blood sugar (FBS) and hemoglobin A1C (HbA1c) were measured at baseline, 12 weeks, and 24 weeks in these patients, and the mean of FBS and HbA1C in three-time assessments were considered as the FBS and HbA1C variables. The statistical analysis was performed by SPSS software version 22. Results: About 46.8% in T1DM and 36.5% in the control groups were male. There was a significant difference between groups regarding blood groups (p-value: 0.042). Although the frequency of B+ was 33.8% and 19.8% in the T1DM and controls, respectively, AB+ and O+ were more prevalent in the controls. The mean of FBS was significantly different between groups (p-value: 0.023). Conclusions: The findings revealed that patients with blood group B are more likely to develop T1DM whereas those with blood group O showed a lower tendency towards diabetes.

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.

In 2014, the membrane-bound protein CD59 became a blood group antigen. CD59 has been known for decades as an inhibitor of the complement system, located on erythrocytes and on many other cell types. In paroxysmal nocturnal haemoglobinuria (PNH), a stem cell clone with acquired deficiency to express GPI-anchored molecules, including the complement inhibitor CD59, causes severe and life-threatening disease. The lack of CD59, which is the only membrane-bound inhibitor of the membrane attack complex, contributes a major part of the intravascular haemolysis observed in PNH patients. This crucial effect of CD59 in PNH disease prompted studies to investigate its role in other diseases. In this review, the role of CD59 in inflammation, rheumatic disease, and age-related macular degeneration is investigated. Further, the pivotal role of CD59 in PNH and congenital CD59 deficiency is reviewed.

Abstract Background. Previous studies have demonstrated an association between ABO blood groups and many types of disease. The present study primarily aimed to identify associations between ABO blood groups, RhD groups and mortality/morbidity outcomes in critically ill patients both in a main cohort and in six pre-defined subgroups. The secondary aim was to investigate any differences in transfusion requirement between the different ABO blood groups and RhD status.Methods. Adult patients admitted to any of the five intensive care units (ICUs) in Skåne, Sweden, between February 2007 and April 2021 were eligible for inclusion. The outcomes were mortality analysed at 28– and 90–days as well as at the end of observation and morbidity measured using days alive and free of (DAF) invasive ventilation (DAF ventilation) and DAF circulatory support, including vasopressors or inotropes (DAF circulation), maximum Sequential Organ Failure Assessment score (SOFAmax) the first 28 days after admission and length of stay. All outcomes were analysed in separate multivariable regression models (adjusted for age and sex), generating odds or hazard ratios for each blood group and RhD status using blood group O and RhD negative as reference. Transfusion requirements were also investigated.Results. In total, 29 512 unique patients were included in the analyses. There were no significant differences for any of the outcomes between non-O blood groups and blood group O, or between RhD groups. In five pre-defined subgroups (sepsis, septic shock, acute respiratory distress syndrome, cardiac arrest and trauma) there were no differences in mortality between non-O blood groups and blood group O or between the RhD groups. The Covid-19 cohort was not investigated given the low number of patients. Furthermore, we could not demonstrate any differences in the number of transfused patients between the ABO blood groups or between the RhD groups.Conclusions. ABO blood type and RhD status do not appear to influence mortality or morbidity in a general critically ill patient population. There were no differences in the number of transfused patients between the ABO blood groups or between the RhD status groups.

   The authors presented the results of experimental studies on the stress-resistant of pigs. The first group is a breed created in Sapphire Ltd. This breed is a breeding group (BG) in purebred breeding and their mixtures in two- and three-breed combinations with Landrace (L) and Duroc (D) boars under conditions of industrial farm technology in Siberia. Two methods assessed stress-resistant of piglets of different breed groups. The first method is “weaning crisis”. The second method is a com-parison of cortisol levels in the blood. Three-breed weanling piglets (SGxL)xD turned out to be the most stress-sensitive. Stress-resistant piglets had an effect on their growth during the rearing period. During this period, stress-resistant animals of all breed combinations had higher average daily gain than stress-sensitive animals (P < 0.001). Stress-resistant animals of the breeding group (SG) showed an average daily growth of 547.5 g during the fattening period. Also, the stress-resistant animals of the breeding group reliably surpassed the stress-sensitive pigs by 461.4 g (P < 0.01), the two-breed pigs by 455.9 g and 404.7 g and the three-breed pigs 451.8 g and 419.2 g, respectively. There was a statistically significant advantage in the indices of the average daily gain among the purebred young-sters of the breeding group (SG) (543 g) compared to the two-breed pigs (447g) and the three-breed pigs (402g), i. e., by 17.8 % and 26 % at P < 0.001. The authors found that the EAAcr/- genotype in stress-sensitive pigs was more common than EAA-/(0.71 ± 0.07 vs 0.48 ± 0.09). Stress-resistant pigs of the breeding group (SG) with EAE edg/edf blood group genotypes were characterized by increased growth intensity and reliable superiority over stress-sensitive pigs. The authors believe that these genotypes can be accepted as preliminary candidates for genetic markers of stress resistant. Blood cortisol levels appeared to be unrelated to stress-resistant compared to the “weaning crisis” method. This relationship (blood cortisol level with stress-resistant) applies to all studied breed combinations, both individually and as a whole.

Objective The aim of this study was to investigate the association between blood groups and severity of peripheral artery disease (PAD) using TASC II classification. Methods The patients who were diagnosed with PAD were retrospectively analyzed. The patients with 50% or more stenosis in the aorto-iliac or femoro-popliteal region detected by conventional or CT angiography were included in the study. These patients were divided into TASC II A, B, C, and D groups considering the severity of PAD. All patients’ blood groups were recorded and compared between TASC II groups. Results While 38% of the study population was O blood group, 61% were non-O group. On the other hand, 90% of the entire study population were RH positive and 10% were RH negative. Non-O blood ratio was found to be significantly higher in patients with higher TASC II groups. (TASC IIA 51.6% vs. TASC IIB 57.9% vs. TASC IIC 61.3% vs. TASC IID 76.6%, p< .001) However, the frequencies of Rh types were similar in all groups. Multiple logistic regression analysis was applied for determining the predictors of severity and complexity of PAD (TASC II C and TASC II D lesions) Conclusions Our study results revealed a clear association between ABO blood groups and severity of peripheral arterial disease. Non-O blood group was found to be the independent predictor of severe and complex PAD.
