Systemic inflammation in cardiovascular and periodontal disease: comparative study

Area of Science:

• Immunology
• Cardiovascular Medicine
• Periodontology

Background:

• Epidemiological studies suggest periodontal disease (PD) is a risk factor for cardiovascular disease (CVD).
• The underlying mechanism may involve local infection triggering systemic inflammatory responses that promote atherosclerosis.

Purpose of the Study:

• To compare levels of systemic inflammatory mediators in individuals with PD, CVD, both, or neither condition.
• To investigate the association between periodontal disease, cardiovascular disease, and specific inflammatory markers.

Main Methods:

• Sera from subjects with PD, CVD, both, or neither were analyzed for C-reactive protein (CRP), serum amyloid A (SAA), ceruloplasmin, alpha(1)-acid-glycoprotein (AAG), alpha(1)-antichymotrypsin (ACT), sICAM-1, and sVCAM.
• Enzyme-linked immunosorbent assays and radial immunodiffusion assays were employed.
• Immunohistochemistry examined SAA and CRP deposition in carotid artery specimens.

Main Results:

• CRP levels were significantly elevated in subjects with PD, CVD, or both, with the highest increase in those with both conditions (threefold).
• SAA and ACT levels were significantly higher in subjects with both PD and CVD compared to those with only one condition or neither.
• Ceruloplasmin increased in subjects with CVD alone, and sVCAM increased in all subjects with CVD. SAA and CRP were found in atherosclerotic lesions.

Conclusions:

• The findings support the hypothesis that localized periodontal infection can influence systemic inflammatory mediator levels.
• Elevated inflammatory mediators may contribute to the development and progression of atherosclerosis.
• Periodontal disease is implicated as a significant contributing factor to cardiovascular disease risk through inflammatory pathways.
