Study Title | Linking bacterial metabolites to disease-associated microbes to uncover mechanisms of host-microbial interactions in intestinal inflammation. Human stool profiling |
Study Summary | Understanding the role of the gut microbiome in inflammatory and autoimmune diseases requires the identification of microbial molecular effectors and their link to host pathophysiology. Here, we present a framework to identify and characterize novel microbial metabolites in patient samples and to directly link their production to disease-associated microbes. We applied this approach to investigate the spectrum of disease severity and treatment response in ulcerative colitis (UC) using longitudinal metabolite and strain profiles combined with paired plasma profiles. |

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. |
