Abstract:Background and Purpose-The association between cerebrovascular events and periodontitis has been found in few studies based on clinical periodontal examinations. However, evidence on the association between periodontal pathogens and stroke is lacking. Therefore, the aim of the study was to investigate whether elevated levels of serum antibodies to major periodontal pathogens predict stroke in a case-control study. Methods-The study population comprised 6950 subjects (aged 45 to 64 years) who participated in th… Show more
“…These results are supported by recent studies showing that elevated serum anti-A. actinomycetemcomitans antibody levels predict stroke 28) and coronary heart disease. 29) A. actinomycetemcomitans possesses a number of putative virulence factors, including a leukotoxin that targets and destroys specific host immune cells (neutrophils and monocytes).…”
SUMMARYRecent epidemiological studies suggest that periodontitis is an important risk factor for coronary heart disease (CHD). The aim of this study was to evaluate the association between periodontitis and CHD, particularly acute coronary syndrome (ACS), focusing on microbiological and immunological features.Twenty-eight CHD patients, 15 with ACS and 13 with chronic CHD, were included in this study. Coronary angiography, periodontal examination, and dental radiography were performed in all patients. Subgingival plaque, saliva, and blood samples were analyzed for the periodontopathogens Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythensis, Treponema denticola, and Prevotella intermedia using polymerase chain reaction.Specific serum antibody titers to the 5 periodontal pathogens were determined by enzyme-linked immunosorbent assay. It was found that 33% of the ACS patients (5/15) harbored A. actinomycetemcomitans in oral samples, whereas no A. actinomycetemcomitans (0/13) was found in the chronic CHD patients (P < 0.05). Furthermore, ACS patients showed significantly higher serum IgG titers to A. actinomycetemcomitans (P < 0.05) compared with chronic CHD. More tooth loss and alveolar bone loss were noted in ACS patients than in chronic CHD patients, although the differences were not statistically significant.Periodontal pathogens, particularly A. actinomycetemcomitans, may play a role in the development of ACS.

“…In relation to CVD, increased levels of circulating antibodies towards periodontal bacteria, including both P. gingivalis and A. actinomycetemcomitans , have been associated with increased carotid intima-media thickness [18], and shown to be predictive of future myocardial infarction [19] and stroke [20]. Also, cross-sectional and case-control studies have reported positive associations between levels of antibodies against A. actinomycetemcomitans and P. gingivalis and the presence of coronary heart disease within large population-based cohorts [21–23].…”
Objectives: The aim was to elucidate whether levels of circulating antibodies to Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis correlate to loss of attachment, as a marker for periodontitis and cardiovascular disease (CVD).
Design: Sera were collected from 576 participants of the Danish Health Examination Survey (DANHES). Immunoglobulin G antibodies against lipopolysaccharide (LPS) and protein antigens from the a, b and c serotypes of A. actinomycetemcomitans and P. gingivalis were quantified by titration in ELISA plates coated with a mixture of antigens prepared by disintegration of bacteria.
Results: Levels of antibodies against P. gingivalis (OR = 1.48) and A. actinomycetemcomitans (1.31) associated with periodontitis, as determined by univariable logistic regression analysis. These antibody levels also associated with CVD (1.17 and 1.37), respectively, However, after adjusting for other risk factors, including age, smoking, gender, alcohol consumption, overweight, and level of education using multivariable logistic regression analysis, only increasing body mass index (BMI; 1.09), previous smoking (1.99), and increasing age (decades) (2.27) remained associated with CVD. Increased levels of antibodies against P. gingivalis (1.34) remained associated with periodontitis after adjusting for other risk factors.
Conclusions: CVD and periodontitis were associated with levels of IgG antibodies to P. gingivalis or A. actinomycetemcomitans in univariable analyses, but only the association of P. gingivalis antibody levels with periodontitis reached statistical significance after adjustment for common confounders. Age, in particular, influenced this relationship.
“…23 For the purpose of epidemiological studies, 3 clinical parameters are typically recorded to assess the prevalence of PD: (1) Bleeding on probing, (2) pocket depth, and (3) clinical attachment level, which reflects the amount of periodontal tissue loss. 3 Other markers of periodontitis include detection of subgingival microbial colonization by selected periodontal organisms [24][25][26][27] and evaluation of serum IgG or IgA antibodies to selected periodontal bacteria [28][29][30][31][32][33][34][35] . to 10-fold higher rates of myocardial infarction and death before the age of 40 years.…”
Coronary artery disease (CAD) is an increasingly important medical and public healthproblem, and is the leading cause of mortality in Bangladesh. Besides conventional risk factors and ethnicity, a number of emerging risk factors may explain the undue prevalence of CAD in this population. Periodontal disease (PD) is one of them, with prevalence of approximately 50%. As with many other diseases, PD is associated with CAD, and the association is independent of conventional risk factors. Low socioeconomic condition, illiteracy and ignorance, metabolic syndrome, nutritional deficiencies including hypovitaminosis D presumably contribute to the prevalence of PD in Bangladesh. In fact, PD and CAD share some cardiometabolic risk factors including diabetes mellitus, obesity and metabolic syndrome. Future research will hopefully explore different aspects of both public health problems, namely, PD and CAD in the country. The information gathered thereby, will help formulate policy to promote good oral health and tackle the deadly epidemic of CAD more efficiently.
