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 two 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 non-existent. We aimed to evaluate the prevalence of and risk factors for absolute and functional ID in paediatric IBD patients while using ZPP and RDW...
