Iron Deficiency in Inflammatory Bowel Disease: The Use of Zincprotoporphyrin and Red Blood Cell Distribution Width

摘要

Objectives: Iron deficiency (ID) in children with inflammatory bowel disease (IBD) is either an absolute (depleted iron stores) or a functional deficiency (caused by chronic inflammation). Differentiating between these 2 types of ID is important because they require a different therapeutic approach. Zinc protoporphyrin (ZPP) and red blood cell distribution width (RDW) are parameters of functional ID. Studies using these parameters to differentiate are nonexistent. We aimed to evaluate the prevalence of and risk factors for absolute and functional ID in paediatric IBD patients while using ZPP and RDW.
