Supplementation With L. Reuteri in H. Pylori Infected Adults

Lama Medical Care s.r.o.56 enrolled

Overview

To determine whether simultaneous use of L. reuteri ProGastria and proton pump inhibitors can eradicate H. pylori in humans in the absence of antibiotics.

Fifty-six (56) subjects, aged 18-70 years will be recruited from patients with dyspeptic symptoms referred to the clinic for consultation about H. pylori infection and who have not previously been treated for this infection. Patients in whom H. pylori infection is confirmed (by endoscopy with biopsy) and who fulfil the inclusion criteria, will be invited to enter the study. After written consent has been obtained subjects will be randomly allocated to one of two groups, one to receive omeprazole (2x20mg/day) + 1 tablet placebo per day and the other to receive omeprazole (2x20mg/day) + 1 tablet (2x108 CFU L. reuteri) ProGastria per day. After randomisation on Day 0 of the study, the subjects will also be asked to complete a gastrointestinal symptom rating score (GSRS) to determine baseline symptomology. Intervention will begin on Day 1 and last for 28 days after which therapy will be stopped. The subjects will be asked to complete the GSRS questionnaire on Day 14 and Day 28. At Day 14, the patients GSRS scores are monitored and the patients interviewed. In those patients where there is a marked deterioration of their condition or symptoms, these will be considered treatment failures and eradication therapy will then be started on Day 15. The day after therapy is stopped (Day 29), patients symptoms will be assessed. All patients will undergo gastroscopy to determine the presence of H. pylori or not. If H. pylori infection is confirmed (by endoscopy and biopsy staining), these subjects will be given triple therapy to eradicate the infection and followed up on Day 90 of the study. On Day 29, those patients that no longer complain of symptoms and are shown to be free of H. pylori infection by endoscopy (treatment success group), will continue with no further therapy until Day 90. On Day 90 all subjects will be given a UBT to determine the presence of H. pylori infection and symptoms will be again assessed using GSRS. Asymptomatic patients with negative breath test will be considered recovered. In those patients where persistent H. pylori infection is confirmed by breath test, second line therapy will be implemented as indicated.

Outcomes

Primary Outcomes

Increase in the number of subjects with treatment success after 28 days of treatment with omeprazole + L. reuteri compared to those given omeprazole + placebo.

Treatment success is defined as the absence of H. pylori infection as shown by a significant reduction in symptoms on Day 28 and by the absence of H. pylori on gastric biopsy at Day 28.

Time frame: 28 days

Secondary Outcomes

Fewer patients in the L. reuteri treatment success group with demonstrated presence of H. pylori infection, measured as UBT on Day 90 compared to the placebo treatment success group

Time frame: 3 months
