Microbiome and Immunosuppression: The Mission Study

The purpose of this research is to study immunosuppression drugs, certain foods, and how they can change the microbiome (the natural microorganisms inside the body) of the individual taking the immunosuppressive medications. The study team wants to study how the microbiome affects how the body processes the transplant medication.

Immunosuppression drugs, like antibiotics and certain foods, can change the microbiome (the natural micro-organisms inside the body) of the individual taking the drug. The study team wants to study what impact these changes to the microbiome have on the individual. The study team is specifically interested in how these changes to the microbiome may change the metabolism (breakdown) and action of medications. It is already known that individual genetics impact the metabolism, absorption, and toxicities of some medications. It is suspected that the microbiome will have similar impacts on medications. With a better understanding of how individual microbiome impacts immunosuppressant medications used to help transplant recipients from rejecting their new organs, providers can more accurately prescribe and dose these medications to better treat and care for transplant patients and their organs. It is expected that participants will be in this research study for up to 12 years. There will be periods of time that requires active participation (visits) and periods of time that will be more passive participation (allowing study staff to follow-up with medical records for outcomes).
