Collection:

Collection ID:CO002554
Collection Summary:Pediatric UC patients (4-17 years of age) were recruited between July 2012 and April 2015 from 29 centers in the USA and Canada and monitored over the course of one year. Patients were treatment-naive at week 0 and received either 5-aminosalicylic acid (mesalamine) or oral/intravenous corticosteroids followed by mesalamine. Up to 4 samples were collected from each patient (week 0, 4, 12 and 52). In addition, metadata and clinical data were collected, including age, gender, ethnicity, treatment, Pediatric Ulcerative Colitis Activity Index (PUCAI), disease progression (colectomy and remission status) and fecal calprotectin (ELISA). Stool samples were frozen at -20 degrees at time of collection by study participants and transported back to the site via freezer gel packs and shipping containers to keep samples frozen during transport. Once at the site, samples were frozen at -80 degrees and batched-shipped with dry ice overnight to the biorepository.

Treatment Summary:NA

Sample Preparation:

Sampleprep ID:SP002567
Sampleprep Summary:Stool samples were homogenized in 10 μL of water per milligram stool sample weight using a bead mill (TissueLyser II; Qiagen) and the aqueous homogenates were aliquoted for metabolite profiling analyses. LC-MS samples were prepared for four profiling methods as follows: HILIC-pos: Metabolites were extracted by adding 90 μL 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) to a 10 μL aliquot of stool homogenate or plasma. Samples were vortexed and then centrifuged (10 min, 9,000 x g, 4°C) to pellet protein precipitates. Supernatants were transferred to glass autosampler vials containing inserts for LC-MS analysis. C8-pos: Lipids were extracted by adding 190 μL of isopropanol containing 1-dodecanoyl-2-tridecanoyl-sn-glycero-3-phosphocholine as an internal standard (Avanti Polar Lipids; Alabaster, AL) to a 10 μL aliquot of stool homogenate or plasma. Samples were vortexed and then centrifuged (10 min, 9,000 x g, ambient temperature) to pellet protein precipitates. Supernatants were transferred to glass autosampler vials containing inserts for LC-MS analysis. HILIC-neg: Metabolites were extracted by adding 120 μL of 80% methanol containing inosine-15N4, thymine-d4 and glycocholate-d4 internal standards (Cambridge Isotope Laboratories; Andover, MA) to a 30 μL aliquot of stool homogenate or plasma. Samples were vortexed and then centrifuged (10 min, 9,000 x g, 4°C) to pellet protein precipitates. Supernatants were transferred to glass autosampler vials containing inserts for LC-MS analysis. C18-neg: Metabolites were extracted by adding 90 μL of methanol containing PGE2-d4 as an internal standard (Cayman Chemical Co.; Ann Arbor, MI) to a 30 μL aliquot of stool homogenate or plasma. Samples were vortexed and then centrifuged (10 min, 9,000 x g, 4°C) to pellet protein precipitates. Supernatants were transferred to glass autosampler vials containing inserts for LC-MS analysis.
