Lactobacillus GG in the Prophylaxis of Ventilator Associated Pneumonia

March 17, 2010 updated by: Creighton University

Lactobacillus GG in the Prophylaxis of Ventilator Associated Pneumonia: A Prospective, Randomized, Placebo-controlled, Double-blind Study

This study utilizes lactobacillus, or probiotics, delivered twice daily to the mouth and stomach, via feeding tube, in effort to determine whether the oral administration of a naturally occurring Lactobacillus species reduces the incidence of ventilator associated pneumonia therefore reducing intensive care unit(ICU)complications.

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

The long-term objective of this research is to determine the utility of altering the oral and gastric bacterial flora in mechanically ventilated patients in order to reduce intensive care unit (ICU)complications. Specifically, our goal is to determine whether the oral administration of a naturally occurring Lactobacillus species reduces the incidence of ventilator associated pneumonia (VAP). ICU admission is commonly accompanied by overgrowth of the natural gastrointestinal (GI) and oropharyngeal flor by pathogenic organisms. Patients requiring endotracheal intubation are predisposed to developing VAP, presumably via micro-aspiration of the altered oropharyngeal flora. By reducing VAP rates, we hope to improve ICU outcomes, minimize ICU expenses, and most importantly, decrease morbidity and mortality.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Placebo Comparator: 2
placebo
Dietary supplement: placebo
Every 12 hours, the contents of a single identical placebo capsule containing the inert plant carbohydrate inulin will be suspended in 3 ml of water-soluble jelly. This suspension will be applied to the oropharyngeal mucosa via sterile syringe. The contents of a second placebo capsule will be suspended in 10 ml of sterile water and pushed through eh NG tube followed by 10 mL of air to ensure complete administration
Active Comparator: 1
Lactobacillus
Dietary supplement: Lactobacillus GG
Every 12 hours, the contents of a single capsule containing Lactobacillus GG will be suspended in 3 ml of water-soluble jelly. The suspension will be applied to the oropharyngeal mucosa via sterile syringe. The contents of a second capsule will be suspended in 10 ml of sterile water and pushed through the NG tub followed by 10 mL of air to ensure complete administration.

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
Time Frame
To determine whether patients given oral Lactobacillus GG will have a smaller increase in the density of pathogenic bacterial in cultures from oral swabs, nasogastric aspirates, and minimally invasive bronchoalveolar lavage samples.
Time Frame: daily while intubated
daily while intubated

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
Time Frame
To assess whether administration of Lactobacillus GG to intubated patients reduces clinically diagnosed VAP,reduces microbiologically diagnosed VAP, affects mortality and duration of mechanical ventilation, and total antibiotic consumption.
Time Frame: daily while intubated
daily while intubated
