Dietary Sugar Absorptive Phenotype for Prediction of Weight Loss Outcome
August 1, 2023 updated by: Dilhana S. Badurdeen, Mayo Clinic
Dietary Sugar Hyper-absorptive Intestinal Phenotype as a Predictor of Weight Loss Post-bariatric Surgery
This study is trying to determine whether the success of bariatric surgery can be predicted by evaluating the dietary sugar absorptive characteristics in the small intestine and if there is any gene expression change on the dietary sugar absorptive characteristics.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
16 years and older (Adult, Older Adult)
Accepts Healthy Volunteers
Yes
Sampling Method
Non-Probability Sample
Study Population
Obese patients scheduled for bariatric surgery (BS) (both men and women of any racial/ethnic background), or lean BS-naïve subjects presenting for surveillance/screening endoscopy procedure as part of their standard medical care (controls).
Description
Inclusion Criteria:
- Obese patients (BMI ≥ 30) scheduled for BS undergoing standard of care screening EGD, or lean BS-naïve individuals (BMI ≤ 25) subjected to EGD for routine clinical indications as part of standard care.
Exclusion Criteria:
- Adults unable to consent, including non-English speakers.
- Pregnant women because endoscopy is a risk factor. All patients of childbearing age undergo history as well as urine pregnancy test as a standard of care prior to undergoing endoscopy as the procedure is performed under anesthesia.
- Prisoners.
- Subjects with preexisting conditions (e.g., bleeding at the time of the procedure, suspected perforation during the standard-of-care procedure) will be excluded from the study at the time of the endoscopy.
- Have a contraindication to endoscopy.
- A history of surgery on the stomach or small intestine.
- Type 1 diabetes (clinical diagnosis and/or positive glutamic acid decarboxylase antibodies).
- Using weight loss medications.
- Active malignancy within the last 5 years.

---|---|
Obese patients scheduled for Bariatric surgery
Subjects scheduled for Bariatric Surgery (BS) and will receive pre-BS Esophagogastroduodenoscopy (EGD) as a part of your standard care will have biopsies from the small intestine taken during the EGD procedure for this study.
|
Upper small intestinal biopsies from patients undergoing BS will be collected during routine standard of care screening EGD and again from the same patients at 1 year during routine standard of care surveillance EGD (esophageal reflux screening/surveillance). Biopsy-derived enteroid cultures and tissue samples from pre- and one-year post BS will be examined for expression level of sugar transporters and gluconeogenic enzymes; glucose and fructose absorption
|
Lean controls naive to Bariatric surgery
Subjects presenting for surveillance/screening EGD procedure as part of their standard medical care will have biopsies from the small intestine taken during the EGD procedure for this study.
