Impact of Intestinal Virome on Pediatric Inflammatory Bowel Disease

2019-06-03 23:49:14 | BioPortfolio


Over the last few years, dysbiosis has emerged as a possible trigger of gut inflammation in inflammatory bowel disease (IBD) and a promising therapeutic target. The complex diversity of microbiota was initially highlighted by the powerful new tools in genetics, including next-generation sequencing (NGS). NGS permitted to decipher the composition of bacterial intestinal communities, but also that of the gut virome. Since then, the evidence of a dynamic instability of the enteric virome in IBD has grown considerably. IBD patients present an expansion of bacteriophages (Caudovirales) associated with decreased bacterial diversity. Moreover, gut virome richness seems to differ between Crohn's disease (CD) and ulcerative colitis (UC) patients. These insights open the gate of new diagnostic, predictive, and therapeutic approaches. However, little is known about pediatric IBD gut virome in terms of variability and evolution under the influence of different treatments (exclusive enteral nutrition, immunosuppressive therapy and biologics). The aim of this study is to evaluate the gut family viral diversity and relative abundance of eukaryotes and prokaryotes in paediatric IBD patients

Medical and Biotech [MESH] Definitions

A gamma-emitting radionuclide imaging agent used in the evaluation of regional cerebral blood flow and in non-invasive dynamic biodistribution studies and myocardial imaging. It has also been used to label leukocytes in the investigation of inflammatory bowel diseases.

A species of Faecalbacterium, previously classified in the FUSOBACTERIUM genus, that is a major constituent of the GUT MICROBIOTA in healthy humans. It has anti-inflammatory activity and reduced numbers of this species occur in patients with INFLAMMATORY BOWEL DISEASES such as CROHN DISEASE.

Loss or absence of normal intestinal function due to nerve damage or birth defects. It is characterized by the inability to control the elimination of stool from the body.

Chronic, non-specific inflammation of the GASTROINTESTINAL TRACT. Etiology may be genetic or environmental. This term includes CROHN DISEASE and ULCERATIVE COLITIS.

A member of the S-100 protein family that is present at high levels in the blood and interstitial fluid in several infectious, inflammatory, and malignant disorders, including rheumatoid arthritis, inflammatory bowel disease, and cystic fibrosis. It is a complex of a light chain (CALGRANULIN A) and a heavy chain (CALGRANULIN B). L1 binds calcium through an EF-hand motif, and has been shown to possess antimicrobial activity.
