Functional GI Disease Registry (FGIDR)

May 6, 2022 updated by: Kyle Staller, MD, MPH, Massachusetts General Hospital
The goal of this study is to establish a prospective observational cohort of individuals with functional GI disorders (functional constipation, irritable bowel syndrome, chronic nausea, functional diarrhea, and functional dyspepsia, as well as a subset of these individuals starting neuromodulation for their functional GI disorder) and collect clinical information and specimens. This information will be used in order to establish a patient registry with detailed clinical data and a specimen repository for future research as well as to specifically identify environmental, genetic, physiological, and psycho-social factors associated with functional GI disorders.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Single Nucleotide Polymorphism (SNP) genotyping
Time Frame: Baseline visit
In this study, we anticipate identifying differential functional genomic profiles (metagenomes) and metabolites (metabolomes) between patients with different functional GI disorders, with detailed species-specific reconstruction of microbial metabolic pathways, their complement of gene orthologs, taxonomic distributions, and abundance profiles.
Baseline visit
Whole genome analysis
Time Frame: Baseline visit
In this study, we anticipate identifying differential functional genomic profiles (metagenomes) and metabolites (metabolomes) between patients with different functional GI disorders, with detailed species-specific reconstruction of microbial metabolic pathways, their complement of gene orthologs, taxonomic distributions, and abundance profiles.
Baseline visit
Proteomics
Time Frame: Baseline visit
