Pregnancy Complications - A Probiotic Interventional Study

June 1, 2022 updated by: Bo Jacobsson, Sahlgrenska University Hospital, Sweden

Investigators hypothesize that

a) probiotics decrease the overall inflammatory state in the pregnant woman, especially in women with high risk pregnancies.

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

The main of the Project is to determine if dietary supplementation intake of probiotics are associated with a decreased inflammatory response in pregnant women, especially those with a history of previous preterm birth or preeclampsia, in a randomized clinical trial. Investigators also want to further investigate the relationship between intake of probiotics and the degree of inflammation in different compartments during pregnancy to see how the probiotic components affect the inflammatory state in the women.

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

Active Comparator: PROBIOTIC in low-risk women
In low-risk women, probiotic group will be treated with the Active ingredient containing Lactobacillus rhamnosus (LGG) (> 10x8 CFU) during all pregnancy until delivery. Capsules contain maltodextrin, LGG and vegetal magnesium stearate.
Drug: probiotic
Low-risk women, women with prior preeclampsia and women with a prior preterm birth will be randomized to be treated with LGG during pregnancy. Effect on maternal and perinatal outcome as well as the effect of treatment on immunological and inflammatory biomarkers will be evaluated.
Other Names:
  • LGG
  • Lactobacillus rhamnosus
Placebo Comparator: PLACEBO in low-risk women

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.
