Metabolic and Metagenomic Effects of Intestinal Microbiome Repopulation in Unexplained Atherosclerosis

Summary

Patients with unexplained atherosclerosis (severe atherosclerosis not explained by traditional risk factors) will receive fecal microbial transplants (FMT) from patients with a Protected phenotype (patients who have high levels of risk factors but little or no carotid atherosclerosis). The objective is to determine what changes in the intestinal microbiome are associated with a decline in plasma levels of toxic metabolites of the itnestinal microbiome such as trimethylamine N-oxide (TMAO) and p-cresylsulfate. The intention is to develop an ecosystem therapeutic of cultured bacteria to treat atherosclerosis.
