Tutkimuksen mukaan ateroskleroosi (rasvojen kertyminen valtimoiden seinämiin) on yhteydessä borrelia vasta-aineisiin eli tutkimus vahvistaa aiempia tutkimuksia infektioiden yhteydestä sydäntauteihin (tässä tapauksessa ateroskleroosiin):

BACKGROUND: Various infectious agents are associated with atherosclerosis. This analysis was performed to investigate relation between seropositivity for anti-Borrelia IgG and carotid atherosclerosis.

METHODS: The cross-sectional Study of Health in Pomerania was conducted in a general community living in a region with endemic Lyme disease. A random sample of 2483 individuals aged 45-79 years was available for the present analysis.

Carotid atherosclerosis was sonographically assessed as intima-media thickness of the common carotid artery and as prevalent atherosclerotic plaques in the extracranial carotid arteries. IgG antibodies to Borrelia were determined by ELISA. RESULTS: IgG antibodies to Borrelia were found positive (>10IU/mL) in 108 subjects (4.3%). Persons with and without positive anti-Borrelia IgG antibodies differed with respect to carotid
intima-media thickness values (0.863+/-0.017mm versus 0.792+/-0.004mm; p<0.001) and prevalent carotid plaques (odds ratio 2.65, 95% confidence interval 1.53-4.61; p=0.001), respectively.

Seropositivity for anti-Borrelia IgG was also associated with both atherosclerotic endpoints when age, sex and further atherogenic risk factors and confounders were included in multivariable statistical models.

CONCLUSIONS: In a region with endemic Lyme disease, seropositivity for anti-Borrelia IgG antibodies is independently associated with atherosclerosis. Our findings add support to the hypothesis that exposure to infectious pathogens increases the atherosclerosis risk.
