Antibiotics do not prevent recurrent myocardial infarcts in subjects with periodontitisJanuary 05, 2006Periodontitis, an infection of the gingiva and tooth-supporting tissues, may influence the effectiveness of antibiotics used for the prevention of recurrent cardiovascular events. A three-month course of treatment with antibiotics decreased recurrence of cardiovascular events in patients without periodontitis, while the medication was found to have no effect in patients with periodontitis. This is the first time dental infections have been linked to the effectiveness of long-term treatment with antibiotics designed to prevent myocardial infarcts. This information was the result of research partially funded by the Academy of Finland and conducted at the Institute of Dentistry, University of Helsinki, and at the Divisions of Cardiology and Infectious Diseases in the Hospital District of Helsinki and Uusimaa. The results of the research are published in the journal Atherosclerosis in January. According to the results, long-term antibiotic medication would prevent myocardial infarcts in patients that do not have periodontitis, or related signs of inflammation such as disease-causing bacteria or antibodies to those bacteria. Periodontitis appears to be such a significant chronic infection that the effect of antibiotic treatment in preventing cardiovascular events is lost in patients that suffer from it. During one year of observation, patients with no signs of periodontitis were more likely to avoid new cardiovascular events. A total of 79% survived without a new cardiovascular event compared with 74% of patients without teeth and 66% of those with periodontitis. The differences in patients under the age of 65 were even more noticeable: 90% of non-periodontitis subjects completed the year without a new cardiovascular event, compared with only 64% of those with periodontitis and 50% of those without teeth. In patients under the age of 65, periodontitis may cause a fivefold increase in the risk of recurrent, acute cardiovascular events in comparison with healthy people. The research material examined 141 patients that were hospitalised for acute cardiovascular events (myocardial infarct or unstable angina pectoris). The double-blind trial involved registering the recurrence of new cardiovascular events over one year of observation following the administration of a three-month course of clarithromycin/placebo. X-rays were used to evaluate the status of teeth and tooth-supporting tissues. The presence of Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis, the two most important periodontal pathogens, was studied in the saliva, and the serum antibodies for these bacteria were measured using a method developed and used only at the Institute of Dentistry, University of Helsinki. Periodontitis is an infection of the gingiva and tooth-supporting tissues that destroys the tissue fibres and alveolar bone that supports the teeth, and may eventually lead to loss of teeth. According to the Health 2000 study, up to 64% of the Finnish adult population has deepened periodontal pockets related to periodontitis and about 20% have a severe form of the disease.

Clarithromycin reduces recurrent cardiovascular events in patients without periodontitis is published online before print in the journal Atherosclerosis on the 4th of January. Academy of Finland |

This suggests the need for increased efforts to prevent and treat periodontitis as a possible means to reduce the risk of this form of cancer. Oral/Body Inflammatory Connection Explained Is your head where your heart is? It may be now. A strong connection between periodontal disease and cardiovascular disease (CVD) has been suggested in recent clinical studies. Patients with moderate to severe periodontitis need evaluation for heart disease risk Additional research is called for and patients with moderate to severe periodontitis should receive evaluation and possible treatment to reduce their risk of atherosclerotic cardiovascular disease (CVD). Over half of people with rheumatoid arthritis have periodontitis Over half (56%) of people with rheumatoid arthritis (RA) also have periodontitis (a chronic inflammatory disease of the gum and surrounding ligaments and bones that hold the teeth in place), displaying fewer teeth than healthy matched controls, high prevalence of oral sites presenting dental plaque and advanced attachment loss (the extent of periodontal support that has been destroyed around a tooth) (chi square p<0.05). Treating gum disease helps rheumatoid arthritis sufferers People, who suffer from gum disease and also have a severe form of rheumatoid arthritis, reduced their arthritic pain, number of swollen joints and the degree of morning stiffness when they cured their dental problems. Scientists find shared genetic link between the dental disease periodontitis and heart attack The relationship between the dental disease periodontitis and coronary heart disease (CHD) has been known for several years. Dental researchers ID new target in fight against osteoporosis, periodontitis Osteoporosis and periodontitis are common diseases whose sufferers must cope with weakness, injury and reduced function as they lose bone more quickly than it is formed. Examining TLR4 influences of B cell response Chronic inflammation, which is at the root of multiple diseases, links periodontal disease to increased incidence of cardiovascular disease. A healthy color About 80 percent of adults suffer from some form of periodontal, or gum disease, which can result in not just tooth loss, but has also been linked to heart disease, diabetes, blood infection, low birth-weight babies, cancer and most recently, obesity. Gene therapy effective treatment against gum disease Scientists at the University of Michigan have shown that gene therapy can be used to successfully stop the development of periodontal disease, the leading cause of tooth loss in adults.
