Brief Summary

The PLANET Study aims to determine the impact of microplastics on intestinal inflammation and gut microbiome in order to understand the role of this pollutant on the risk of developing inflammatory bowel disease (IBD) as well as other diseases. With this information, the researchers hope to characterize better the role of environmental pollutants on IBD and develop novel strategies towards prevention.

Outcome Measures

Primary Outcomes (1)

  • Microplastics quantification

    Measuring the concentration, size and shape distributions of microplastics in the stool samples of women with CD, healthy controls and any relatives (spouses and siblings of the infant).

    1 year

Secondary Outcomes (2)

  • Alpha and beta diversity

    1 year

  • Fecal calprotectin analysis

    1 year

Study Arms (2)

Pregnant people with Crohns disease (Case)

Arm 1 is pregnant people with Crohns disease who enroll with the infant that they are pregnant with at the time.

Pregnant people without Crohns disease (Control)

Arm 2 is the control arm of pregnant people without Crohns disease and other inflammatory bowel diseases who enroll with the infant that they are pregnant with at the time.
