Correlation of ABO Blood Group Phenotype and Rhesus Factor with Periodontal Disease: An Observational Study

Association of ABO phenotype, rhesus factor, platelet count and hemoglobin level with oral hygiene status and severity of chronic periodontitis

Background

The development of periodontal diseases has multifactorial causes including genetic factors. Limited investigations have been conducted to explore the association between ABO blood groups and the development and progression of periodontal diseases.

Aim

To evaluate and assess the association of ABO Phenotype and Rhesus factor with oral hygiene status, severity of chronic periodontitis and blood parameters like hemoglobin level and Platelet count in localized and generalized chronic periodontitis.

Material and methods

Study was carried out on 100 patients, out of which 80 patients of Generalized Chronic Periodontitis and 20 patients of Localized Chronic Periodontitis. Patients were categorized into Mild, Moderate and Severe Periodontitis.

Result

A highly significant association was found between severity of periodontitis and blood groups with blood group B and O were found to be at a greater risk to develop moderate to severe form of chronic periodontitis. Also subjects with blood group B and O showed worst oral hygiene among all the blood groups. Also patients suffering from chronic periodontitis showed a general trend towards lower limit of both hemoglobin level and platelet.

Conclusion

Genetic factors such as ABO blood group antigens may act as a risk influencer that plays a role in progression and severity of the chronic periodontitis, with blood group B and O being worst affected. Another observation was that a long standing case of chronic periodontitis can lead to anemia thus having systemic implications.

Correlation Between ABO Blood Grouping and Erythrocyte Sedimentation Rate (ESR) in Periodontal Diseases

This study investigates the relationship between erythrocyte sedimentation rate (ESR) and ABO blood grouping in the context of periodontal disorders. Periodontal diseases, chronic inflammatory conditions that damage the tissues supporting teeth, can lead to tooth loss if left untreated. ESR, a common hematological test indicating systemic inflammation, has been linked to the severity of periodontal disease. ABO blood grouping, a hereditary trait, is linked to a higher risk of various oral and systemic diseases. By synthesizing existing research, this study explores the potential of the connection between blood type ABO and ESR levels in individuals with periodontal disorders, examining studies that assess the distribution of ABO blood types and corresponding ESR values among periodontal patients.

Relationship of Blood Group with Level of Cooperation of Pediatric Dental Patients

Acquaintance with the behavior of children in dental office setting is highly important in treatment success. People with different blood groups often have different behaviors. Thus, the blood group may aid in prediction of behavior of pediatric dental patients. This study is aimed at assessing the relationship of the blood group with level of cooperation of pediatric dental patients. This cross-sectional study was conducted on 130 children between 4 and 6 years of age. The blood group of children was recorded according to their identification card or by collecting an intraoral blood sample during pulpotomy and using the respective kit. To assess the level of cooperation of children, their behavior was videotaped during the procedure, and the videos were assessed by two pedodontists. The behavior of children was scored according to the Venham scale. Data were analyzed by SPSS 26 and Chi-square, Fisher's exact test, and Mann–Whitney U test. The blood group was A in 35.7%, B in 5.8%, AB in 3.2%, and O in 53.5%. Children with blood group O had maximum cooperation (52.6) while those with blood group B had minimum cooperation. Pairwise comparisons of the groups regarding the Venham scale revealed significant differences between blood groups A and B (P = 0.0001) and also B and O (P = 0.005). Pairwise comparisons of the groups regarding the level of cooperation also revealed significant differences between blood groups A and B (P = 0.0001) and B and O (P = 0.019). Blood group B may be correlated with certain behavioral traits such as dental fear and anxiety and the resultant poor cooperation.

The Relationship Between Periodontal Disease and ABO Blood Groups: A Cross-Sectional Study

PURPOSE

The objective of this cross-sectional study was to evaluate the relationship between ABO blood groups and periodontal diseases.

MATERIALS AND METHODS

Four hundred sixteen subjects (223 females, 193 males) were recruited according to the eligibility criteria. Periodontal examination was performed, including full-mouth plaque index (PI), bleeding on probing (BOP), clinical attachment level (CAL), and interproximal bone loss (IBL). ABO blood group patterns were determined based on self-reports, confirmed by medical records. The chi-squared test was done to evaluate the data (p < 0.05).

RESULTS

Out of the 416 subjects, 52.2% were blood group O, whereas 27.8% were blood group A. 46.8% of patients with blood group O had gingivitis and 49.6% had periodontitis. 31.2% of patients with blood group A had gingivitis,while 29.5% had periodontitis. The blood group with the lowest percentage among patients with gingivitis was AB, with a rate of 6.2%; in this blood group, 8.1% had periodontitis.

CONCLUSIONS

There is no association between periodontal diseases and ABO blood group types.

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.

The Prevalence of Streptococcus Mutans with Different ABO Blood Groups Among Healthy College Students

Objective:

This study was conducted to determine the correlation between the occurrence ofStreptococcus mutans(S. mutans) which is considered as the main pathogen responsible for the initiation and development of dental caries with blood groups and Rhesus (Rh) factor that are considered as a genetic predictor of having dental caries among healthy students.

Methods:

Saliva and blood samples were taken from 40 healthy students whose ages were between 19-23 years old in the College of Dentistry/Al-Iraqia University in Baghdad, Iraq. Estimation of the flow rate and pH was done for all the collected saliva samples within 5 min of saliva collection. Then, 100 µL of saliva was cultured on Mitis salivarius bacitracin agar (MSBA) at 37 °C for 48 h. The colonies ofS. mutanswere identified by their morphology and biochemical tests. Later, 1 to 2 drops of blood were taken from each student’s thumb to determine the blood group.

Results:

This study showed there was a greater prevalence ofS. mutansamong students of blood group A in contrast to the blood group O. In addition, Rh+ groups were dominant than Rh- groups among the study samples.

Conclusion:

S. mutanslevels were higher in the blood group A followed by AB, B, O blood groups among the college students studied.

Lewis and AB0 blood group-phenotypes in periodontitis, cardiovascular disease, obesity and stroke

The AB0 blood group has been linked to ischaemic heart disease, stroke, and periodontal disease, while the Lewis blood group has been linked to ischaemic heart disease and obesity, all of which have been associated with periodontitis. AB0 or Lewis blood group phenotype may therefore constitute common hereditary components predisposing to these disorders. In this study, we investigated if blood group phenotype associated with periodontitis in a subpopulation consisting of 702 participants from a Danish cross-sectional cohort and, secondarily, attempted to confirm their association with hypertension, ischaemic heart disease, stroke, and obesity. No significant association between blood group phenotype and periodontitis was detected, nor were previously reported associations between blood group phenotype and hypertension, ischaemic heart disease, stroke, and obesity confirmed. This may, at least partly, be attributed to differences in study type, outcome definitions, cohort sizes, and population attributable factors. However, our results suggested a strong association between self-reported stroke and the Lewis (a−b−) phenotype (P = 0.0002, OR: 22.28; CI 95: 4.72–131.63).
