Prenatal Probiotic Intervention

January 3, 2022 updated by: Arkansas Children's Hospital Research Institute

Probiotic Supplementation in Obese Pregnant Women. A Feasibility Study.

This study will assess the feasibility of a randomized control trial in which the effects of probiotic supplementation throughout pregnancy on maternal insulin sensitivity and inflammation, as well offspring gene expression and body composition are examined.

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.

Detailed Description

Maternal obesity leads to increased insulin resistance and inflammation which have been shown to induce fetal adaptations and greater risk of obesity in the offspring. Probiotic supplementation during pregnancy has been shown to improve insulin sensitivity in normal weight women. However, little is known on the effects of probiotic supplementation throughout pregnancy on maternal insulin sensitivity and inflammation as well as offspring gene expression and body composition. Long term nutritional supplementation, however, is associated with increased participant burden as well as lower compliance and retention rates. Thus, this study will assess the feasibility of a long term probiotic supplementation study in obese pregnant women. Acceptance and compliance with daily capsules throughout pregnancy and study procedures will be assessed.

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

Yes

Genders Eligible for Study

Female

Inclusion Criteria:

  • BMI ≥ 30
  • ≥ 18 years of age
  • Singleton pregnancy
  • Less than 12 weeks of gestation
  • Less than 1 serving of yoghurt with live cultures or cultured milk per week
  • Conceived without assisted fertility treatments

Exclusion Criteria:

  • • Women with pre-existing medical conditions (e.g., diabetes, hypertension, thyroid disorders, heart disease or immune disorders) as determined by the PI to affect the outcomes of interest

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.
EXPERIMENTAL: Probiotics
Each probiotic capsule contains 180 mg of a standardized white to light beige fine powder consisting of freeze-dried cultures. Specifically, Bifidobacterium BB-12® and Lactobacillus rhamnosus LGG® (50%:50%). This product has a minimum potency of 6.5 billion (6.5E+9) CFU (ColonyForming Units) per capsule. Other ingredients in the powder are: microcrystalline cellulose, maltodextrin, silicon dioxide and magnesium stearate. Participants in this group will take one daily capsule orally starting at the time of recruitment (gestation week 12) and until delivery.
Dietary supplement: Probiotics
Bifidobacterium BB12 and Lactobacillus Rhamosus LGG (50%:50%) capsules.
Other Names:
  • live cultures
PLACEBO_COMPARATOR: Placebo
Participants in this group will take one capsule containing microcrystalline cellulose, maltodextrin, silicon dioxide and magnesium stearate (all ingredients listed in the probiotic capsules except the culture) . Participants in this group will take one daily capsule orally starting at the time of recruitment (gestation week 12) and until delivery.
Dietary supplement: Placebo
capsule manufactured to mimic probiotic capsules.

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
