IBD Briefs: Upadacitinib in Children, Predicting Crohn’s Disease, and Autoimmune Diseases Associated with IBD

J Runde et al. J Pediatr Gastroenterol Nutr. 2025;80:133–140. Upadacitinib is associated with clinical response and steroid-free remission for children and adolescents with inflammatory bowel disease

In this single-center retrospective study, n=20 (3 CD, 13 UC, 4 IBD-U), steroid-free clinical remission (SF-CR) was seen in 75% (16/20) following induction and maintained in 65% (11/17) reaching Week 24 of therapy

J Gaifem et al. Nature Immunology 2024; 25: 1692-1703. Open Access! A unique serum IgG glycosylation signature predicts development of Crohn’s disease and is associated with pathogenic antibodies to mannose glycan.

“Analysis of preclinical serum samples, up to 6 years before IBD diagnosis (from the PREDICTS cohort), revealed the identification of a unique glycosylation signature on circulating antibodies (IgGs)…[which] elicits a proinflammatory immune pathway through the activation and reprogramming of innate immune cells.”

Using Danish registry and 50-fold matched controls, there was a significant increase for a large number of autoimmune diseases: The adjusted hazard ratio after full follow-up was 4.72 for psoriatic arthritis, 5.21 for spondyloarthritis, 2.77 for celiac disease, 2.15 for rheumatoid arthritis, 1.69 and 1.64 for type 1 and type 2 diabetes, respectively. For thyroid disease, it was 1.16.
