A Study of the Effect of Probiotics on Gastrointestinal Function During Pregnancy

August 7, 2023 updated by: University of California, Davis

The purpose as well as the aim of this project is to understand the effect of probiotics on gastrointestinal (GI) dysfunction such as nausea, vomiting, and constipation that are found during the first and second trimesters of pregnancy.

The primary objective of this project is to uncover whether probiotics have an effect on GI functional disorders.

The secondary objective is to identify the microbiota associated with probiotic intake.

The tested hypothesis is that gut microbiota influences the GI functions and may influence constipation, nausea, and vomiting during pregnancy.

Study Overview

Status

Status

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

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Definition of healthy or low risk pregnant women:

  • Systolic blood pressure < 140 mmHg and diastolic blood pressure < 90 mmHg
  • Hemoglobin ≥ 10.0 g/dL
  • Have immunity against rubella (German measles)
  • HIV negative

  • Urine test shows no sign of kidney or urinary tract infection

    • 27 weeks 6 days gestation or less with confirmed fetal heart beat

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.
Other: Probiotic 10 (Nature's Bounty)
The suggested dose will be two (2) pills of Probiotic 10 (Nature's Bounty) after dinner daily. Subjects will be asked to take probiotics for six (6) days after providing baseline fecal specimen. Subjects will self-report their daily GI function including the frequency of nausea, vomiting, and bowel movement(s). Then, the subjects will stop taking probiotics for two (2) days and resume taking probiotics for another six (6) days. This six (6)-day on and two (2)- day off cycle is repeated two (2) times.
Dietary supplement: Probiotic 10 (Nature's Bounty)
The Probiotic 10 (Nature's Bounty) that contains 20 billion live cultures of Lactobacillus plantarum 299v (Lp299v®), Lactobacillus bulgaricus Lb-87, Lactobacillus paracasei DSM 13434, Lactobacillus plantarum DSM 15312, Lactobacillus salivarius Ls-33, Lactobacillus brevis Lbr-35, Lactobacillus acidophilus La-14, Bifidobacterium lactis Bl-04, Lactobacillus paracasei Lpc-37, Lactobacillus casei Lc-11, which are under Lactobacillus and Bifidobacterium.

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
Number of vomiting and nausea per day
Time Frame: 16 days following baseline fecal sample collection
Using scale of 1-5, quantify the seriousness of sick to the stomach, dry heaves, fatigue, lack of energy, and feeling blue.
16 days following baseline fecal sample collection

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
The relative quantity of gut bacteria at phylum, family, and species level when patients take or do not take Probiotic-10.
Time Frame: 16 days following baseline fecal sample collection
To receive at least six (6) analyzable fecal specimens including one prior to taking probiotics from 33 subjects to identify the microbiota associated with probiotic intake.
16 days following baseline fecal sample collection
