Effects of a Probiotic Supplementation on Symptoms and Microbiome Characteristics in Patients With Non-celiac Gluten/Wheat Sensitivity.

Italy30 participantsStarted 2018-09-10

Plain-language summary

The aim of this randomized, double-blind, placebo-controlled clinical trial is to investigate the effects of probiotics on symptoms and gut microbiota composition following gluten reintroduction. The study included adults diagnosed with NCWS. Participants received a 6-week intervention with either probiotics or a placebo. For the first 4 weeks, all participants followed a gluten-free, low-FODMAP diet, after which gluten was reintroduced. Gastrointestinal symptoms (using the modified Gastrointestinal Symptom Rating Scale (GSRS)) and fecal samples were collected at baseline (T0), after 4 weeks (T1), and after 6 weeks (T2). Gut microbiome composition was assessed through whole-shotgun metagenomic sequencing and fecal volatile organic compounds (VOCs) were analyzed using gas chromatography-mass spectrometry (GC-MS).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion criteria: * age≥18 years * NCGWS demonstrated by the following self-reported conditions i) intestinal and extra intestinal symptoms associated within hours or days after the ingestion of gluten-containing food, ii) a clear benefit while on a gluten-free diet, iii) relapse of symptoms with the ingestion of gluten-containing foods, iv) a positive response to the double-blind placebo-controlled (DBPC) cross-over gluten challenge test, as previously described. Exclusion criteria: * presence of Crohn disease (CD), wheat allergy (WA), irritable bowel syndrome (IBS), and other gastrointestinal diseases, H. Pylori infection, lactose intolerance, history of gastrointestinal surgery, liver/pancreatic diseases, active or recent infection diseases, known psychiatric diseases, any systemic diseases * pregnancy or breastfeeding * active use of antibiotics, pre-probiotics, immunosuppressive drugs, non-steroidal anti-inflammatory drugs, or corticosteroids, * inability to give written informed consent.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Change in Symptoms Following Gluten Reintroduction

Timeframe: Symptoms were assessed at baseline (T0), after 4 weeks of a gluten-free diet (T1), and after 2 weeks of gluten reintroduction (T2).
