Low Dose Bismuth Versus Lactobacillus Reuteri for H. Pylori Eradication (LactoBismu)

April 24, 2019 updated by: Maria Pina Dore, Università degli Studi di Sassari

Twice-a-day PPI, Tetracycline, Metronidazolequadruple Therapy With Pylera® or Lactobacillus Reuteri for Treatment naïve or for Retreatment of H. Pylori: Two Randomized Pilot Studies

This study investigates the efficacy of a b.i.d. quadruple therapy containing Pylera® or L. reuteri for H. pylori infection.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Bismuth, metronidazole and tetracycline yielded high cure rates for H. pylori infection. Earlier studies suggested that the bismuth quadruple therapy may be effective when given twice-a-day rather than q.i.d. and that b.i.d. therapy was associated with fewer side effects. The addition of the probiotic Lactobacillus reuteri (Gastrus®) to Lactobacillus reuteri (Gastrus®) that has been shown to increase the cure rates by 10-14%. In another study bismuth supplementation with L. reuteri DSM 17938, in a modified low dose quadruple therapy provided good eradication rates (93.3%; 95% CI : 85-99%) in clinical practice.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Helicobacter pylori eradication rate
Time Frame: 30-40 days after the end of treatment
a negative 13C-urea breath test and/or a negative stool antigen test
30-40 days after the end of treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Compliance and side effects evaluation
Time Frame: 30-40 days
Patient interview at the end of treatment
30-40 days
