Link between atherosclerosis and small intestinal bacterial overgrow

Link between atherosclerosis and small intestinal bacterial overgrow

This study evaluated whether there was a link between subclinical atherosclerosis (hardening of the arteries) and small intestinal bacterial overgrowth (SIBO).  Thirty nine patients were enrolled and received a glucose hydrogen breath test to assess for SIBO.  In the group 30.8% were positive for SIBO. Atherosclerosis was determined using  levels of dephosphorylated-uncarboxylated matrix Gla-protein and pulse-wave velocity. There existed a statistically significant correlation between SIBO and atherosclerosis leading the researchers to conclude that SIBO testing might be a good screening tool for early stage atherosclerosis.
