Summary
Hepatitis C virus (HCV) RNA was found in carotid artery plaques, suggesting local infection and a potential role in atherosclerosis. This finding highlights a possible direct viral impact on cardiovascular disease progression.
Area of Science:
- Cardiovascular Research
- Hepatology
- Virology
Background:
- Hepatitis C virus (HCV) infection is linked to increased atherosclerosis risk.
- Studies suggest an association between HCV and carotid artery plaque development.
Purpose of the Study:
- To detect HCV genomic sequences in plaque tissues.
- To identify HCV replicative intermediates within atherosclerotic plaques.
Main Methods:
- Prospective recruitment of HCV-infected patients with chronic ischemic heart disease.
- Analysis of carotid plaque tissues for HCV RNA.
- Detection of HCV replicative intermediates and sequencing of viral RNA.
Main Results:
- HCV RNA detected in 7/16 carotid plaque samples from infected patients.
- HCV RNA found in plaque but not serum in 3 patients.
- HCV replicative intermediates identified in 3 plaque samples; genotypes 1 and 2 observed.
Conclusions:
- Presence of HCV RNA in plaque suggests active local infection.
- HCV may exert a direct local effect on carotid atherosclerosis.
- This finding supports a potential viral contribution to cardiovascular pathology.
