Abstract

It remains unclear whether or not human intestinal spirochetosis (HIS) has any associated symptoms or lesions. In this study, we assessed the prevalence of HIS in sessile serrated adenomas/polyps (SSA/Ps) and their possible association. Following identification of early cecal cancer with SSA/P accompanied by a colonization of HIS, we went on to conduct a retrospective case-control study using endoscopically resected SSA/P specimens to examine the frequency of HIS infection in SSA/Ps. Nineteen SSA/P cases and 172 controls were obtained. The rate of HIS infection was significantly higher at 52.6% (10/19) in the SSA/P cases compared to the controls at 8.1% (14/172). Our SSA/P series were associated with a remarkably higher rate of HIS than controls or than previously reported. This is the first report to provide evidence for potential association between HIS and SSA/Ps. (C) 2014 Elsevier GmbH. All rights reserved.
