RT Journal Article SR Electronic T1 Big data in IBD: big progress for clinical practice JF Gut JO Gut FD BMJ Publishing Group Ltd and British Society of Gastroenterology SP 1520 OP 1532 DO 10.1136/gutjnl-2019-320065 VO 69 IS 8 A1 Nasim Sadat Seyed Tabib A1 Matthew Madgwick A1 Padhmanand Sudhakar A1 Bram Verstockt A1 Tamas Korcsmaros A1 Séverine Vermeire YR 2020 UL http://gut.bmj.com/content/69/8/1520.abstract AB IBD is a complex multifactorial inflammatory disease of the gut driven by extrinsic and intrinsic factors, including host genetics, the immune system, environmental factors and the gut microbiome. Technological advancements such as next-generation sequencing, high-throughput omics data generation and molecular networks have catalysed IBD research. The advent of artificial intelligence, in particular, machine learning, and systems biology has opened the avenue for the efficient integration and interpretation of big datasets for discovering clinically translatable knowledge. In this narrative review, we discuss how big data integration and machine learning have been applied to translational IBD research. Approaches such as machine learning may enable patient stratification, prediction of disease progression and therapy responses for fine-tuning treatment options with positive impacts on cost, health and safety. We also outline the challenges and opportunities presented by machine learning and big data in clinical IBD research.
