Study TitleLongitudinal Metabolomics of the Human Microbiome in Inflammatory Bowel Disease
Study SummaryA number of factors contribute to the complex array of small molecules that occur in stool; including diet, gut flora, and gut function. Comprehensive profiling of the stool metabolome therefore can provide detailed phenotypic information on health status, metabolic interactions between the host and the microbiome, and interactions among gut microbes. Here, we applied metabolomics to characterize stool samples collected longitudinally from inflammatory bowel disease (IBD) patients and non-IBD controls who participated in the Integrative Human Microbiome Project (iHMP). A total of 546 stool samples were analyzed using a platform comprised of four complementary liquid chromatography tandem mass spectrometry (LC-MS) methods designed to measure polar metabolites and lipids. Each method used high resolution/accurate mass (HRAM) profiling to measure both metabolites of confirmed identity and yet to be identified metabolite peaks. 81,867 de-isotoped LC-MS peaks were measured, out of which 597 were annotated based on confirmation with authentic reference standards. Pooled stool extracts inserted and analyzed throughout the analysis queues to evaluate analytical reproducibility showed a median coefficient of variation of 5.1% among known metabolites and 24.2% across all 81,867 features. Owing to differences in water content and heterogeneity among stool samples, total median scaling was used to standardize the metabolomics data. In addition to being accessible at the Metabolomics Workbench repository, these metabolomics data will be incorporated into a multi’omic database (https://www.hmpdacc.org/ihmp/) that will enable the study of associations between the gut microbiome and IBD.

Project Title:Longitudinal Multiomics of the Human Microbiome in Inflammatory Bowel Disease
Project Summary:The Inflammatory Bowel Disease (IBD) Multi'omics Database (IBDMDB) includes multi’omics measurements from over 100 subjects, sampled biweekly over up to a year in both adult and pediatric patients with IBD (Crohn’s disease and ulcerative colitis), along with non-IBD controls. Data types include fecal metagenomes, metatranscriptomes, metabolomes, and proteomes, as well as host genetics, intestinal biopsy transcriptomes, epigenetics, and 16S amplicon profiles. Subjects’ medical histories and demographics are collected at baseline and medication, diet, and disease activity profiled longitudinally.

Collection:

Collection ID:CO000955
Collection Summary:Stool samples were collected by subjects in tubes containing 5 ml of 100% Ethanol and shipped to collection sites. A portion of each stool sample (40-100 mg) and the entire volume of ethanol preservative were stored in 15 mL centrifuge tubes at -80 °C until all samples were collected.
Sample Type:Stool
Additives:Ethanol

Treatment:

Treatment ID:TR000975
Treatment Summary:NA

Sample Preparation:

Sampleprep ID:SP000968
Sampleprep Summary:Samples were thawed on ice and then centrifuged (4 ˚C, 5,000 x g) for 5 minutes. Ethanol was evaporated using a gentle stream of nitrogen gas using a nitrogen evaporator (TurboVap LV; Biotage, Charlotte, NC) and stored at -80 ˚C until all samples in the study had been dried. Aqueous homogenates were generated by sonicating each sample in 900 μl of H2O using an ultrasonic probe homogenizer (Branson Sonifier 250) set to a duty cycle of 25% and output control of 2 for 3 minutes. Samples were kept on ice during the homogenization process. The homogenate for each sample was aliquoted into two 10 μL and two 30 μL in 1.5mL centrifuge tubes for LC-MS sample preparation and 30 μL of homogenate from each sample were transferred into a 50 mL conical tube on ice to create a pooled reference sample. The pooled reference mixture was mixed by vortexing and then aliquoted (100 μL per aliquot) into 1.5 mL centrifuge tubes. Aliquots and reference sample aliquots were stored at -80 °C until LC-MS analyses were conducted. Pairs of pooled reference samples were inserted into the queue at intervals of approximately 20 samples in order to assess analytical variance and as a reference to standardize within and across batches by “nearest neighbor” scaling.

Chromatography:

Chromatography ID:CH001066
Chromatography Summary:LC-MS samples were prepared from stool homogenates (10 μL) via protein precipitation with the addition of nine volumes of 74.9:24.9:0.2 v/v/v acetonitrile/methanol/formic acid containing stable isotope-labeled internal standards (valine-d8, Isotec; and phenylalanine-d8, Cambridge Isotope Laboratories; Andover, MA). The samples were centrifuged (10 min, 9,000 x g, 4°C), and the supernatants injected directly onto a 150 x 2 mm Atlantis HILIC column (Waters; Milford, MA). The column was eluted isocratically at a flow rate of 250 μL/min with 5% mobile phase A (10 mM ammonium formate and 0.1% formic acid in water) for 1 minute followed by a linear gradient to 40% mobile phase B (acetonitrile with 0.1% formic acid) over 10 minutes.

Chromatography Summary:LC-MS samples were prepared from stool homogenates (30 μL) via protein precipitation with the addition of four volumes of 80% methanol containing inosine-15N4, thymine-d4 and glycocholate-d4 internal standards (Cambridge Isotope Laboratories; Andover, MA). The samples were centrifuged (10 min, 9,000 x g, 4°C) and the supernatants were injected directly onto a 150 x 2.0 mm Luna NH2 column (Phenomenex; Torrance, CA). The column was eluted at a flow rate of 400 μL/min with initial conditions of 10% mobile phase A (20 mM ammonium acetate and 20 mM ammonium hydroxide in water) and 90% mobile phase B (10 mM ammonium hydroxide in 75:25 v/v acetonitrile/methanol) followed by a 10 min linear gradient to 100% mobile phase A.

The supernatants (10 μL) were injected onto a 150 x 2.1 mm ACQUITY BEH C18 column (Waters; Milford, MA). The column was eluted isocratically at a flow rate of 450 μL/min with 20% mobile phase A (0.01% formic acid in water) for 3 minutes followed by a linear gradient to 100% mobile phase B (0.01% acetic acid in acetonitrile) over 12 minutes.

After centrifugation (10 min, 9,000 x g, ambient temperature), supernatants (10 μL) were injected directly onto a 100 x 2.1 mm ACQUITY BEH C8 column (1.7 μm; Waters; Milford, MA). The column was eluted at a flow rate of 450 μL/min isocratically for 1 minute at 80% mobile phase A (95:5:0.1 vol/vol/vol 10 mM ammonium acetate/methanol/acetic acid), followed by a linear gradient to 80% mobile-phase B (99.9:0.1 vol/vol methanol/acetic acid) over 2 minutes, a linear gradient to 100% mobile phase B over 7 minutes, and then 3 minutes at 100% mobile-phase B.
