Advantages of Proactive Therapeutic Drug Monitoring in a Prospective Cohort of Children With Inflammatory Bowel Disease Treated With Anti-Tumour Necrosis Factor

Abstract

Few studies have addressed whether proactive therapeutic drug monitoring (TDM) results in improved clinical outcomes in children with inflammatory bowel disease (IBD) treated with anti-tumour necrosis factor. The aim of this study was to investigate the impact of using proactive TDM in this patient group.Pilot single-centre observational study to accrue data on patients managed with proactive TDM.More patients in the proactive TDM cohort were managed by escalating the infliximab (IFX) regime (P < 0.001). The need for switching to different biologics was significantly lower in this patient group (P < 0.001).The introduction of proactive TDM resulted in a significant reduction of patients requiring switch of their primary biologic. The results of this study are indicators that proactive TDM offers a better method of managing children with IBD on IFX therapy.
