Efficacy of Probiotics in Patients With Functional Dyspepsia

A study published in The Lancet Gastroenterology & Hepatology shows that patients with refractory functional dyspepsia treated with spore-forming probiotics had a higher decrease in the postprandial distress syndrome (PDS) score than with placebo.

The analysis included 68 patients with functional dyspepsia and a baseline PDS score of one or greater, meaning they had at least mild symptoms. The participants were randomly assigned to receive eight weeks of treatment with probiotics (n=32) or placebo (n=36) twice per day, followed by an open-label extension phase of 8 weeks. The primary endpoint was a decrease of at least 0.7 in the PDS score.

The results show that the proportion of clinical responders was higher with probiotics (48%) than with placebo (20%). These beneficial effects were also maintained with probiotics during the open-label extension phase. The number of patients with adverse events was similar in both groups.

Despite the absence of major shifts in relative or quantitative faecal microbiota community composition, the proportional increase in Faecalibacterium was also associated with probiotic efficacy, the authors say.

The changes in immune activation were more pronounced in patients with functional dyspepsia on proton-pump inhibitors, suggesting additional beneficial effects of probiotics as an add-on therapy.
