The use of anti-tumour necrosis factor-α (anti-TNF) therapy has seen a rise over the last 15 years in paediatric inflammatory bowel disease (PIBD). Whether this has translated into preventing complications and avoiding surgery in childhood is less certain. Data from the Wessex PIBD cohort were analysed to assess for trends in anti-TNF therapy and surgical intervention.
All patients diagnosed with PIBD within Wessex from 1997–2017 were eligible. Prevalence of anti-TNF and yearly surgery rates (resection and perianal) during childhood ( < 18 years of age) were analysed by Pearson’s correlation, multiple linear regression and Fisher exact test.
825 children were included in the analysis (498 Crohn’s disease, 272 ulcerative colitis, 55 IBDU), mean age at diagnosis 13.62 years (1.59-17.64 years), 327 (39.6%) female. The prevalence of patients treated with anti-TNF therapy increased from 5.05% to 27.11% (2007–17),
The time from diagnosis to resection increased from 1.57 to 5.11 years,
The incidence of surgery in those treated (16.1%) or untreated (12.2%) with anti-TNF agents was no different (
There is an increase in the number of patients treated with anti-TNF therapy alongside a statistically significant decrease in the surgical resection rate. Despite this, children diagnosed at younger ages were still undergoing surgery during childhood. These data suggest that anti-TNF therapy may modify the natural history of IBD, reducing the need for surgical intervention.
