The distribution of the ABO blood groups among diabetes mellitus patients in Qatar

Relationships of ABO and Rhesus blood groups with type 2 diabetes mellitus: a systematic review and meta-analysis

OBJECTIVES

The susceptibility to type 2 diabetes mellitus (T2DM) has been linked to blood type. We aimed to characterize the relationships of the ABO and Rhesus blood groups with T2DM.

METHODS

Literature searches were performed using the Medline, PubMed, Scopus, Cochrane, EMBASE, and Google Scholar databases to identify studies published up to 31 March 2022. The PRISMA guidelines were used for reporting. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were obtained using fixed-effects models.

RESULTS

Twenty-six studies of 6870 patients with T2DM and 11,879 controls were identified. Compared with the other ABO groups, people with blood type B were at higher risk of T2DM (OR: 1.30, 95% CI: 1.20-1.41), while group O was associated with a lower risk (OR: 0.92, 95% CI: 0.86-0.98). There were no significant associations of T2DM with blood types A or AB, or Rh factor.

CONCLUSION

Individuals with blood type B are at higher risk of developing T2DM. Therefore, they should be screened for T2DM on a frequent basis and be made aware of the importance of maintaining a balanced diet and regular exercise for the prevention of obesity and T2DM.

Association of blood groups/Rh and diabetes mellitus in Karachi city, Pakistan

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.

The Correlation Between Blood Group Type and Diabetes Mellitus Type II: A Case-Control Observational Study From Pakistan

Introduction

Adult-onset type 2 diabetes mellitus (T2DM) is defined as a chronic hyperglycemic state, characterized by insulin resistance and declining islet B-cell function, eventually leading to islet B-cell function failure. The present study evaluated the association of T2DM with the type of blood group. 

Methodology

A case-control study was conducted from April 2020 to September 2021 in Karachi, Pakistan. An electronic questionnaire was used to determine if there is an association between ABO blood groups and type 2 diabetes mellitus. Our study involved two groups with an equal number of participants. The patient group contained participants who had been diagnosed with type 2 diabetes mellitus, whereas the control group contained participants who had never been diagnosed with type 2 diabetes mellitus. Information was collected through a self-administered electronic questionnaire which was circulated through social media.

Results

The mean ± SD age was reported to be 25.98 ± 12 years. The study found a significant association between blood group B and type 2 diabetes mellitus (p=0.006), whereas a negative association was seen between the blood group O and type 2 diabetes mellitus (p=0.001). It should be noted, however, no significant association was found between the blood groups A and AB and type 2 diabetes mellitus (p>0.05).

Conclusion

The results of this study indicate that there is an association between type 2 diabetes mellitus and the ABO blood group system; a significant association was found between blood group B and risk of type 2 diabetes mellitus (T2DM). Nevertheless, we recommend regular screening for T2DM in individuals with a high-risk profile. Those at risk can adopt measures that are beneficial for them in the long run such as dietary control and physical exercise. Further studies using explorative techniques with a diversified population are recommended. 

Association of ABO and Rh Blood Group Phenotypes with Type 2 Diabetes Mellitus at Felege Hiwot Comprehensive Referral Hospital Bahir Dar, Northwest Ethiopia

BACKGROUND

ABO and Rh blood group antigens are thought to be among genetic determinants of type 2 diabetes mellitus. Identification of blood group phenotypes are more associated with type 2 diabetes mellitus. It will be helpful for individuals who are susceptible blood groups to take care of themselves by avoiding other predisposing factors and taking preventive measures.

METHODS

Hospital-based comparative cross-sectional study was carried out from February to April 2019 at Felege Hiwot Comprehensive Referral Hospital. Sociodemographic and clinical data were collected with a semistructured pretested questionnaire. ABO and Rh Blood group were determined by slide and test tube methods. Biochemical parameters were determined with Mindray BS-200E fully automated clinical chemistry analyzer. Data were analyzed by IBM SPSS version 20 statistical software. Chi-square test and logistic regression analysis were employed for data analysis. A P value of < 0.05 was considered statistically significant.

RESULTS

From a total of 424 participants included for this study, blood group O was found higher in frequency with 74 (34.9%) and 97 (45.75%) for cases and healthy controls, respectively. ABO blood groups showed significant association with T2DM, a chi-square value of 12.163 and P value of 0.007. However, the Rh blood group was not associated with T2DM. Binary logistic regression analysis revealed that blood group B had a higher risk (OR: 2.12, 95% CI: 1.33-3.32) and blood group O had decreased risk (OR: 0.636, 95% CI: 0.43-0.94) of T2DM as compared to other blood groups.

CONCLUSION

ABO blood group antigens showed significant association with type 2 diabetes mellitus. Blood group B was associated with an increased risk and O blood group with decreased risk of type 2 diabetes mellitus.

The epidemiological plateau of Corona virus in Gulf countries: a descriptive statistics study

The novel SARS-CoV-2 belongs to the beta coronaviruses and causes a severe pandemic disease named as COVID-19. In late December 2019. WHO situation reports on 11 March 2020, declared that COVID-19 a pandemic due to its global spread. All Arab countries have reported COVID-19 cases. The confirmed cases of COVID-19 pandemic in Arab gulf countries were reported in the United Arab Emirates, Iraq, Bahrain, Oman, Qatar, Kuwait, and Saudi Arabia, respectively. The fatality case rates in Gulf Countries are less than 1% in Oman, UAE, Kuwait, Bahrain, and Saudi Arabia, yet it hits 7.5% in Iraq. In this manuscript, we try to interpret the pandemic statistically in gulf countries, especially in Iraq. Additionally, the distribution of COVID-19 confirmed cases based on ABO blood groups were investigated. Epidemiological analyses revealed that a decreased risk of infection was attributed to blood group O compared to non-O blood groups, whereas people with the A and A.B. blood groups showed the highest risk for COVID-19 infection. Besides, high risk for diabetes, cardiovascular disease, blood clotting, and interleukin secretion was also related to blood groups in different orders. Accordingly, patients with a specific blood group that are associate with the above diseases should be under strict medical surveillance when infected with COVID-19 to reduce complications and severity. This study provides further confirmation for the previously reported correlation between the ABO blood groups and the susceptibility to COVID-19 infection.

Higher Odds of Type 2 Diabetes for Some Blood Groups

BACKGROUND

Diabetes is one of the most common metabolic diseases in humans that cause disruption in glucose and fat metabolism. The determination of the ABO blood group system is hereditary and both diabetes and blood groups have a genetic basis.

OBJECTIVES

The aim of this study was to investigate the odds of type 2 diabetes for some blood groups.

METHODS

This case-control study was conducted in hospitals of Kermanshah in 2018. The case group consisted of patients with diabetes admitted to hospital and the control group of nondiabetic patients hospitalized in the surgical ward. Information such as age, sex, BMI, family history of diabetes and blood group is collected and analyzed by the univariate and multivariate logistic regression method.

RESULTS

A total of 750 patients were enrolled in this study. The number of participants in both groups was 375. The average ages of the participants were 50.51 and 51.62 years, respectively. 67.5% of the patients in the case group were female in comparison with 73.6% of those in the control group. The value of Rh+ in the case and control groups was 94.4 and 93.6%, respectively (p = 0.645). The chance of having diabetes for patients with blood group A was 76% higher than for those with blood group O (p = 0.006).

CONCLUSION

According to the results of this study, the odds of type 2 diabetes for people in blood group A was higher than for those in other blood groups. It is recommended that blood group A be considered as a risk factor in the screening of type 2 diabetes.

Biologic roles of the ABH and Lewis histo-blood group antigens part II: thrombosis, cardiovascular disease and metabolism

The ABH and Lewis antigens were among the first of the human red blood cell polymorphisms to be identified and, in the case of the former, play a dominant role in transfusion and transplantation. But these two therapies are largely twentieth-century innovations, and the ABH and related carbohydrate antigens are not only expressed on a very wide range of human tissues, but were present in primates long before modern humans evolved. Although we have learned a great deal about the biochemistry and genetics of these structures, the biological roles that they play in human health and disease are incompletely understood. This review and its companion, which appeared in a previous issue of Vox Sanguinis, will focus on a few of the biologic and pathologic processes which appear to be affected by histo-blood group phenotype. The first of the two reviews explored the interactions of two bacteria with the ABH and Lewis glycoconjugates of their human host cells, and described the possible connections between the immune response of the human host to infection and the development of the AB-isoagglutinins. This second review will describe the relationship between ABO phenotype and thromboembolic disease, cardiovascular disease states, and general metabolism.
