Development of a Preparation for Supportive Supplementation of Probiotics in Patients With Reflux
A two-arm, double-blind, randomized, placebo-controlled study investigating the efficacy of a probiotic preparation developed as supportive supplementation of probiotics in patients with reflux.
The objective of this trial is to evaluate the effect of the probiotic dietary supplement on the diversity and composition of the gut microbiome in patients diagnosed with GERD who are on PPI therapy. The study will also monitor changes in the oral microbiome and the impact of probiotic supplementation on patient quality of life and GERD symptoms.
Patients will take the probiotic preparation, 2 tablets twice daily (morning before meals and evening after meals). The experimental phase will last 6 weeks. Patients in the control arm will receive placebo. Supplementation will be discontinued if adverse effects occur.
Oral and rectal swabs will be taken before and after administration of the preparation. Patients will monitor their symptoms using a questionnaire.
