Outcomes Associated with Delayed Diagnosis in Pediatric Crohn’s Disease

A Ricciuto et al. Journal of Crohn’s and Colitis; 2020. jjaa197, https://doi.org/10.1093/ecco-jcc/jjaa197 Link: Diagnostic Delay Is Associated with Complicated Disease and Growth Impairment in Paediatric Crohn’s Disease

Methods: “We conducted a national, prospective multi-centre IBD inception cohort study, including 1399 children. Diagnostic delay was defined as time from symptom onset to diagnosis >75 th percentile.”

Key findings:

  • In CD, diagnostic delay was associated with a 2.5-times higher rate of strictures/internal fistulae (HR 2.53, 95% CI 1.41-4.56)
  • Every additional month of diagnostic delay was associated with a decrease in height-for-age z-score of 0.13 standard deviations
  • Diagnostic delay was more common in CD, particularly small bowel CD

My take: Delays in diagnosis in this study were associated with stricturing/internal fistulising complications and growth impairment in paediatric CD.  It is likely that inadequate treatment would increase the risk of these problems as well.
