This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
The goal of this clinical trial is to learn if a fiber (psyllium) can change the way bacteria use fructans (a type of sugar) and whether psyllium can help decrease childhood irritable bowel syndrome (IBS) symptoms when eating fructans. The main questions it aims to answer are: Aim 1: The effect of psyllium at two doses given with a fructan meal on microbial fructan fermentation (intracolonic pH; H2 gas production; gut microbiome composition; fecal short-chain fatty acids, lactate, glycomics). Aim 2: Determine the impact of psyllium given with a fructan meal on fructan-induced GI symptoms. Participants will first be asked to eat a specific diet over two three-day periods to determine if fructans worsen their IBS symptoms. Those with worsening symptoms with fructans will be asked to participate in the second part of the study. This includes two weeks of baseline (no change in diet) and two weeks of eating a specific diet with fructans with either psyllium or glucose. Participants will be asked to complete pain and stool diaries, submit stool specimens, swallow a pill to capture gut acid levels, and give breath samples.
Assessing Psyllium Given With Meals for Fructan Sensitivity in Children With Irritable Bowel Syndrome
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.
