Article Synopsis
  • Ulcerative proctitis (UP) is a rare form of ulcerative colitis in children, with the study analyzing clinical features and outcomes of 196 diagnosed patients aged under 18 from 2016 to 2020.
  • Most patients presented with symptoms like bloody stools and abdominal pain, and the study found that higher initial disease activity scores (PUCAI) were linked to worse outcomes, including the need for more aggressive treatments.
  • By the end of the study, nearly half of the patients showed disease progression, and only a small percentage required colectomy, highlighting the challenges in managing UP in pediatric patients.

Background: Recent trials suggested that the Crohn's disease (CD) exclusion diet (CDED) plus partial enteral nutrition (PEN) is a safe and effective strategy in remission induction of paediatric-onset CD. However, real-world evidence regarding the safety and efficacy of the CDED plus PEN approach is still lacking. The present case-series study reported our experience with the outcomes of CDED plus PEN in the paediatric-onset CD at disease onset and after the loss of response to biologics.

Vitamin D deficiency is an environmental factor involved in the pathogenesis of inflammatory bowel disease (IBD); however, the mechanisms surrounding its role remain unclear.

A potential link between vitamin D deficiency and dysregulated autophagy is microRNA (miR)-142-3p, which suppresses autophagy.
