The GETAID: 40 years of a family story in IBD.

The Groupe d'Etude sur les Affections Inflammatoires Digestives (GETAID) was founded in Paris in 1983 by Professor R Modigliani and colleagues. From the beginning, the aim of this international (France, Belgium and Switzerland), multicentre, French-speaking group was to address clinical questions raised by patients or physicians in their daily practice or the inflammatory bowel diseases community, by focusing on clinical research on treatments through randomised controlled trials, prospective cohorts and cross-sectional studies, quantifying the severity of various facets of the disease when necessary for these studies. This approach very innovative has contributed to the advancement of knowledge in inflammatory bowel diseases by publishing more than 120 original articles in peer-reviewed journals throughout the GETAID 40-year history, most of them in top publications in gastroenterology and hepatology journals. In this paper, we will see what GETAID's contribution has been over the last four decades, review reasons for success and forthcoming challenges.
