Study Overview
Brief Summary
To assess the differential expression of IBD-related microbiome-derived biomarkers including bacterial strains and peptides such as antimicrobial peptides (AMP) found in inner-colonic samples (HygiSample™) in comparison to home collected stool samples in patients with active IBD colonic disease.
The HygiSample will be collected during a defecation-inducing high-volume (>40 L) colon irrigation bowel prep (HygiPrepⓇ).
Detailed Description
This study is a preliminary study aimed to assess the ability to differentially detect IBD-related microbiome-derived biomarkers in colon effluent samples collected using the Hygieacare System. The proposed sample size of 20 patients (10 in the control arm, 10 in the IBD arm), where each patient provides both stool and three inner-colonic samples is sufficient to provide preliminary results for such an assessment.
Categorical variables will be summarized by frequencies and percentages, while quantitative variables will be summarized by descriptive statistics (mean, median, standard deviation, minimum, and maximum).
The investigators will compare taxonomy and phylogeny biodiversity between the control and the IBD arms and between stool and colon effluent samples.

Inclusion Criteria
- •The patient's age is between 18 and 80 years old
- •For study arm - patients with known colonic IBD based on colonoscopic findings - diagnosed with either Ulcerative Colitis or Crohn's Disease scheduled for surveillance colonoscopy.
- •For control arm - patients scheduled for routine colonoscopy without active IBD symptoms or IBD diagnosis
Exclusion Criteria
- •The patient has an underlying condition that in the opinion of the investigator may adversely affect the patient's ability to understand, comply with, or follow protocol instructions
- •History of intestinal resection (appendectomy allowed)
- •Active Clostridium difficile colitis
- •Antibiotic use for 2 months prior to colonoscopy
- •The patient has any of the contraindications listed below:
- •congestive heart failure, intestinal perforation, carcinoma of the rectum, fissures or fistula, severe hemorrhoids, abdominal hernia, renal insufficiency, cirrhosis, pregnancy, or recent colon, rectal, or abdominal surgery
Outcomes
Primary Outcomes
Detection of IBD-related microbiome-derived biomarkers in stool samples
Time Frame: analysis end of study enrollment
Each patient provides both stool (when possible) and inner-colonic samples. The samples will be analyzed to identify microorganisms' presence and abundance, diversity, and functional genomics. Specifically, we will look at the alpha and beta diversity of the microbiota (% of prediction on the most dominant vectors of the system) and the taxonomic differences between the samples - represented by percentages over taxonomic groups. If the data allows (based on our omics results), we will look at the potential abundance of calprotectin (IBD biomarker, % from control). We will analyze the data for the study participants by age, gender, BMI (average, median, standard deviation), and prevalence of underlying diseases. The questionnaires will be used to find correlations between the patient's overall health, exercise routine, nutritional habits, and diet. Results will be presented using R\^2 when applies.
unpaired T-test
Time Frame: analysis end of study enrollment
We will track the patients demographic and physiological parameters - age (years), gender (male/female), height (feet inches), weight (lbs), BMI. We will collect information about the patients eating, heath, and exercise habits using a questionnaire.
cox wilcoxon test
Time Frame: through study completion, an average of 1 year
We will track the patients demographic and physiological parameters - age (years), gender (male/female), height (feet inches), weight (lbs), BMI. We will collect information about the patients eating, heath, and exercise habits using a questionnaire
Secondary Outcomes
- Alpha diversity(through study completion, an average of 1 year)
- Differential abundance analysis(through study completion, an average of 1 year)
- Shannon index(through study completion, an average of 1 year)
- beta diversity(through study completion, an average of 1 year)
