Atherosclerosis: an infectious disease?
1University of Maryland School of Medicine, Baltimore, USA.
Insights
Infectious pathogens like Helicobacter pylori may contribute to atherosclerosis, a condition where arteries harden. Research suggests specific antibiotic treatments could impact outcomes in managing this cardiovascular disease.
Area of Science:
- Cardiovascular Science
- Infectious Disease
- Pathology
Background:
- Traditional risk factors inadequately explain the development of atherosclerosis.
- Emerging evidence implicates infectious agents in the atherosclerotic cascade.
Purpose of the Study:
- To explore the role of infectious pathogens in atherogenesis.
- To investigate potential mechanisms linking infection to atherosclerosis.
- To assess the impact of antibiotic therapy on outcomes.
Main Methods:
- Review of existing evidence on pathogens and atherosclerosis.
- Analysis of proposed pathogenetic mechanisms.
- Consideration of clinical implications of antibiotic interventions.
Main Results:
- Identified Helicobacter pylori, cytomegalovirus, and Chlamydia pneumoniae as potential contributors.
- Highlighted mechanisms including macrophage transformation, endothelial injury, inflammation, and thrombosis.
- Suggested a potential role for antibiotic therapy in managing atherosclerosis.
Conclusions:
- Infectious pathogens represent a significant, yet often overlooked, factor in atherogenesis.
- Understanding these infectious links may reveal novel therapeutic strategies.
- Targeting specific pathogens with antibiotics could be a viable approach to managing atherosclerotic disease.
Abstract:
Traditional risk factors do not fully account for atherogenesis. There is increasing evidence that infectious pathogens, such as Helicobacter pylori, cytomegalovirus, and Chlamydia pneumoniae, may promote the atherosclerotic cascade. Proposed mechanisms include macrophage transformation, endothelial injury, chronic inflammation, and thrombosis. Specific antibiotic therapy may affect outcome.
