Background And ObjectivesAnaemia and iron deficiency (ID) are common complications in inflammatory bowel disease (IBD). In patients undergoing iron therapy, intravenous iron supplementation is recommended in preference to oral therapy. This study evaluated routine practice in the management of IBD-associated anaemia and ID to verify implementation of international treatment guidelines.Materials And MethodsGastroenterologists from nine European countries (n=344) were surveyed about their last five IBD patients treated for anaemia (n=1404). Collected information included tests performed at anaemia diagnosis, haemoglobin (Hb) levels and iron status parameters, the anaemia treatment given and, if applicable, the iron administration route.ResultsSelection of diagnostic tests and treatment for IBD-associated anaemia varied considerably across Europe. Anaemia and iron status were mainly assessed by Hb (88%) and serum ferritin (75%). Transferrin saturation was only tested in 25% of patients. At diagnosis of anaemia, 56% presented with at least moderate anaemia (Hb<10 g/dl) and 15% with severe anaemia (Hb<8 g/dl). ID (ferritin<30 ng/ml) was detected in 76%. Almost all patients (92%) received iron supplementation; however, only 28% received intravenous iron and 67% oral iron. Management practice was similar in 2009 and 2011.ConclusionIn clinical practice, most IBD patients received oral iron even though this administration route may aggravate the disease, and despite international guidelines recommending intravenous administration as the preferred route. The high frequency of ID suggests insufficient monitoring of iron status in IBD patients. There is a need to increase awareness and implementation of international guidelines on iron supplementation in patients with IBD.
