AbstractThe presence or absence of blood group antigens has been associated with various diseases, with antigens also acting as receptors for infectious agents. There is paucity of literature available in assessing the relative liability of blood group phenotypes to periodontal diseases. The objective of this study was to determine the association of the ABO blood group and Rhesus factor with periodontal disease to assess whether they can behave as predictors of periodontal diseases. The data was collected from randomly selected 100 individuals who were referred to the Department of Periodontics & Implantology, Mahatma Gandhi Dental College & Hospital, Jaipur for periodontal ailment management or for other reasons related to dental health. The subjects were categorized into three groups according to Russel's Periodontal index: healthy periodontium, gingivitis & periodontitis. Blood samples were collected to identify the ABO blood group and Rh factor by the slide method. The effect of blood subgroups on periodontal health, gingivitis and periodontitis was investigated separately. Results & Conclusion: More number of healthy subjects in blood group A. Gingivitis and periodontitis were found more in blood group O and blood group AB, respectively. Rh positive subjects had higher distribution in all study groups.

AbstractHepatocellular carcinoma (HCC) is one of the most common types of cancer worldwide. There are many factors in the etiology of HCC such as hepatitis B virus (HBV), hepatitis C virus (HCV), alcohol, obesity, smoking and aflatoxin. Many types of cancer are assumed to be associated with ABO blood group and Rhesus factor (RH). In this study we aimed to evaluate the relationship between tumor characteristics and overall survival (OS), ABO blood group and RH factor in patients with HCC. A total of 507 patients with chronic liver disease (252 patients with HCC and 255 patients without HCC) were included in the study. All demographic, clinic and laboratory (biochemical parameters and blood type) features were collected retrospectively. The mean age of the patients was 54.50 ± 9.30. There was no significant difference in both ABO groups and RH factors between the two groups. We found that vascular invasion rate of the tumor was higher in the B blood group and multicentric localization of tumor was significantly higer in patients with positive RH but there was no difference between OS in ABO and RH blood groups. In addition, the tumor was less multicentric in the AB blood group. Blood groups and RH factor can be used to predict the prognosis in cirrhotic patients with HCC.

The Relationship

We have been experiencing a global pandemic with baleful consequences for mankind, since the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was first identified in Wuhan of China, in December 2019.  So far, several potential risk factors for SARS-CoV-2 infection have been identified. Among them, the role of ABO blood group polymorphisms has been studied with results that are still unclear. The aim of this study was to collect and meta-analyze available studies on the relationship between SARS-CoV-2 infection and different blood groups, as well as Rhesus state. We performed a systematic search on PubMed/MEDLINE and Scopus databases for published articles and preprints. Twenty-two studies, after the removal of duplicates, met the inclusion criteria for meta-analysis with ten of them also including information on Rhesus factor. The odds ratios (OR) and 95% confidence intervals (CI) were calculated for the extracted data. Random-effects models were used to obtain the overall pooled ORs. Publication bias and sensitivity analysis were also performed. Our results indicate that blood groups A, B and AB have a higher risk for COVID-19 infection compared to blood group O, which appears to have a protective effect. An association between Rhesus state and COVID-19 infection could not be estabished.
