MA Aardoom et al. JCC 2021; https://doi.org/10.1093/ecco-jcc/jjab171 The incidence and characteristics of venous thromboembolisms in paediatric-onset inflammatory bowel disease; a prospective international cohort study based on the PIBD-SETQuality Safety Registry

Design: 2016-2020: paediatric gastroenterologists prospectively replied to the international Safety Registry, monthly indicating whether they had observed a VTE case in a patient <19 years with IBD. n=24,802 PIBD patients

Key findings:

• Twenty cases of VTE were identified (30% Crohn’s disease)
• The VTE incidence was 3.72 [95%CI 2.27 – 5.74] per 10,000 person-years, 14-fold higher than in the general pediatric population (0.27 [95%CI 0.18-0.38], p<0.001)
• All but one patient had active IBD, 45% were using steroids and 45% hospitalized.
• Cerebral sinus venous thrombosis was most frequently reported (50%) VTE

My take: The absolute risk of VTE is low in the pediatric population. In those with active disease, the presence of CVC and use of steroids are known risk factors and require consideration of, at minimum, nonpharmacologic interventions.
