What this trial studies

This interventional trial gives the Symprove probiotic drink to adults with biopsy‑confirmed coeliac disease who are in histological remission but continue to have gastrointestinal symptoms. Eligible participants are aged 18–65, have a normal or near‑normal duodenal biopsy (Marsh 0 or I) within the past 12 months, and have followed a strict gluten‑free diet for at least six months. Participants will take the probiotic daily and symptom measures will be recorded before and after the treatment period to see if symptoms improve. Common exclusions include recent antibiotic or probiotic use, pregnancy or lactation, and other significant gastrointestinal disorders, and the trial is run at Sheffield Teaching Hospitals.

Who should consider this trial

Good fit: Adults 18–65 with biopsy‑confirmed coeliac disease in histological remission (Marsh 0 or I), on a strict gluten‑free diet for at least six months, and with persistent gastrointestinal symptoms for at least six months.

Not a fit: People who are pregnant or breastfeeding, recently used antibiotics or probiotics, have other major gastrointestinal diseases, are not adherent to a gluten‑free diet, or are outside the 18–65 age range are unlikely to qualify or benefit.

Why it matters

Potential benefit: If successful, Symprove could reduce persistent gut symptoms and improve day‑to‑day quality of life for people with coeliac disease who remain symptomatic despite a gluten‑free diet.

How similar studies have performed: Probiotic treatments have produced mixed results in small trials for IBS‑type symptoms and have not been definitively proven for persistent symptoms in coeliac disease.
