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.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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
In low-risk women, placebo group will be treated with the placebo ingredient during all pregnancy until delivery. The capsules of the placebo Group have similar content but lack the probiotic lactic acid bacteria which has been replaced by maltodextrin to make the mg amount equal.
Drug: placebo
Low-risk women, women with prior preeclampsia and women with a prior preterm birth will be randomized to be treated with placebo during pregnancy. Effect on maternal and perinatal outcome as well as the effect of treatment on immunological and inflammatory biomarkers will be evaluated.
Active Comparator: PROBIOTIC in women with a prior PTB
In women with a prior preterm birth (PTB), 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 women with a prior PTB
In women with a prior preterm birth (PTB), placebo group will be treated with the placebo ingredient during all pregnancy until delivery. The capsules of the placebo Group have similar content but lack the probiotic lactic acid bacteria which has been replaced by maltodextrin to make the mg amount equal.
Drug: placebo
Low-risk women, women with prior preeclampsia and women with a prior preterm birth will be randomized to be treated with placebo during pregnancy. Effect on maternal and perinatal outcome as well as the effect of treatment on immunological and inflammatory biomarkers will be evaluated.
Active Comparator: PROBIOTIC in women with a prior PE
In women with a prior preeclampsia (PE), 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 women with a prior PE
In women with a prior preeclampsia (PE), placebo Group will be treated with the placebo ingredient during all pregnancy until delivery. The capsules of the placebo Group have similar content but lack the probiotic lactic acid bacteria which has been replaced by maltodextrin to make the mg amount equal.
Drug: placebo
Low-risk women, women with prior preeclampsia and women with a prior preterm birth will be randomized to be treated with placebo during pregnancy. Effect on maternal and perinatal outcome as well as the effect of treatment on immunological and inflammatory biomarkers will be evaluated.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Inflammatory modulation of Lactobacillus Rhamnosus in low risk mothers.
Time Frame: at recruitment, week 25, week 35 of gestation
