Briefly noted: SC Shah, H Khalili et al. Gastroenterol 2018; 155: 1079-89.
This study evaluated pooled data with 207,600 incident cases of IBD from a population of 478 million. Key findings:
- Female patients had lower a lower risk of Crohn’s disease during childhood until 10-14 years of age, but then a risk afterwards
- For ulcerative colitis, there was a divergence in risk after 45 years of age, when men had a significantly higher incidence.
My take: the differences indicate that genetic factors (men with a Y chromosome and only one chromosome X) along with sex hormones play a role in the pathogenesis of IBD.
AGREE proceedings: Briefly noted: ES Dellon, CA Liacouras, J Molina-Infante, GT Furuta et al. Gastroenterology 2018; 155: 1022-33. This report provides updated recommendations from AGREE conference –which have been widely cited previously on this blog and elsewhere. One of the remarkable features on this report is the fact that there are 64 authors (by my count) –thus reading the affiliations and the conflict of interest disclosures alone would take some time.
