The Role of Mucosal Microbiome in Recurrence of Clostridioides Difficile Infection
The Role of Mucosal Microbiome in Recurrence of Clostridioides Difficile Infection
The study is being done to identify types of bacteria associated with the lining of the large
 intestine in people who have recently been treated for C. difficile infection to determine if
 there are features associated with recurrent disease.
Patients who have recently been diagnosed with C. difficile infection and completed treatment
 will be enrolled to undergo evaluation of the colonic mucosa via sigmoid biopsies.
 Participants will also complete surveys, blood draw and stool collection. Overall goals are
 to identify whether C. difficile is persisting in the colon mucosa after treated infection,
 and whether this, and other clinical and microbiome factors may be playing a role in disease
 recurrence.
Inclusion criteria:

 -  Adults aged 18 and over

 -  Confirmed C. difficile infection based on positive C. difficile toxin PCR testing and
 clinical evidence of diarrhea

 Exclusion criteria:

 -  Known pregnancy

 -  Prior diagnosis of C. difficile infection within 2 months of this diagnosis

 -  Other known active gastrointestinal infectious process

 -  Known diagnosis of inflammatory bowel disease, microscopic colitis, celiac disease or
 other inflammatory conditions

 -  Vulnerable adults

 -  Any other disease(s), condition(s) or habit(s) that would interfere with completion of
 study, or in the judgment of the investigator would potentially interfere with
 compliance to this study or would adversely affect study outcomes.
